DESCRIPTION OF THE EMBODIMENTS

An embodiment of the present invention will be described with reference to the drawings.FIG.1shows a portable facility1according to one embodiment of the present invention. The portable facility1includes a power generation unit3and a function unit5. The power generation unit3includes a first housing H1, and a wind power generation device7and a solar power generation device9attached to the first housing H1. The function unit5includes a second housing H2and an electric apparatus11disposed inside the second housing H2. The power generation unit3and the function unit5are connected by a power supply cable13, and the electric apparatus11of the function unit5is supplied with power from the power generation unit3to operate.

As shown inFIG.2, the first housing H1includes a substantially rectangular top wall15, a substantially rectangular bottom wall17, and four surrounding walls19disposed between the top wall15and the bottom wall17and has a substantially cube shape as a whole. The second housing H2also has the same configuration as that of the first housing H1. More specifically, in the present embodiment, freight containers having a same configuration are used as the first housing H1and the second housing H2. In the following description, the first housing H1and the second housing H2are collectively described with referring to a “housing H,” unless the distinction between them is necessary in particular.

The term “freight container” as used herein may preferably refer to a container having a standard dimension for freight transport, for example, a container having a dimension meeting a domestic standard for container transport. The container having a “standard dimension” as used herein may be, for example, a container having a dimension meeting a standard established by a domestic administrative body or international authorities such as the International Organization for Standardization (ISO), or a JR container which has been established as a de facto standard for rail freight containers in Japan.

Since the housing H is constituted by a freight container, the housing can be transported by different transportation equipments such as automobiles, railroad cars, ships, and airplanes. Since the freight container has excellent robustness, it is possible to prevent damage due to vibration and/or impact during transport. Because of the robustness, the freight container also has excellent crime prevention performance against intrusion from the outside. Therefore, it is possible to reduce the cost for operating the facility. In particular, since both housings H1, H2have a same configuration, i.e., are constituted by containers having a same size, it is possible to effectively use a freight space and an installation space in a case where a plurality of units of the containers are transported and installed.

As shown inFIG.1, the wind power generation device7of the present embodiment includes a wind turbine21and a power generator23which is driven by the wind turbine21to generate electric power. The wind turbine21is constructed as a vertical-axis wind turbine. Specifically, the wind turbine21includes a plurality of (two in this example) blades25and a blade support body27for supporting the blades25. The respective blades25extend in a vertical direction, and the blade support body27is supported at an upper end of a support column29through a non-illustrated bearing so as to be rotatable about a vertical axis. The two blades25are disposed at positions having a phase shift of 180° around the axis of the support column29. In this example, the support column29is fixed to an upper center part of one surrounding wall of the surrounding walls19of the first housing H1.

The power generator23of the wind power generation device7is disposed inside a power generator casing31attached to an upper portion of the support column29. A fixed ring of the bearing is attached to the power generator casing31, and a rotary ring of the bearing is coupled to the blade support body27. As the wind turbine21rotates, a rotor of the power generator23rotates along with the rotary ring inside the power generator casing31, so that the power generator23generates electric power. The power generator23may be, for example, an induction power generator or a synchronous power generator.

Since the vertical-axis wind turbine21can receive wind to generate electric power, albeit its relatively small configuration, it is suitable as a wind turbine21for the wind power generation device7provided to the portable facility1. It should be noted that the wind turbine21may be a horizontal-axis wind turbine.

The solar power generation device9of the present embodiment includes a solar panel33which receives sunlight to perform photoelectric conversion and a panel mount35for attaching the solar panel33to the housing H. In this example, the solar panel33is attached to an upper side15aof the top wall15of the housing H through the panel mount35. The solar panel33may be disposed on a surrounding wall19of the first housing H1depending on the direction of solar radiation and installation environment or may be deployed around the first housing H1. It should be noted that although the panel mount35of the illustrated example has a simple plate-like configuration, the panel mount35may include a mechanism capable of inclining the solar panel33in accordance with the direction of the sun.

Although the present embodiment is described with reference to an example in which the power generation unit3of the portable facility1includes the wind power generation device7and the solar power generation device9, the power generation unit3may include a hydraulic power generation device (not illustrated), in addition to these power generation devices. The hydraulic power generation device includes a water turbine which is placed in water of a water channel and is rotated by flow of the water and a power generator which is driven by rotation of the water turbine. Where the portable facility1includes a hydraulic power generation device, for example, the housing H is placed by the side of the water channel, and the hydraulic power generation device is supported by a surrounding wall19of the housing H which is located on the side of the water channel.

It is sufficient that the power generation unit3includes at least one power generation device, namely, the wind power generation device7, the solar power generation device9, and/or the hydraulic power generation device. Where the portable facility1includes all of the wind power generation device7, the solar power generation device9, and the hydraulic power generation device, however, the power generation amount is less likely to be limited by natural environment such as weather conditions and topographical features, and/or time of the day or night, so that the facility can be set up and be operated with a greater applicability to a wide range of areas.

The power generation unit3may further include a system power source connection part for receiving power supply from a system power source. Provision of the system power source connection part in the power generation unit3makes it possible, when the facility is set up at a site where the facility can be connected to a system power source, to use the power generation unit3as a main power source for the function unit5, while using the system power source to compensate for a temporary shortage of power generation when it occurs, or to use the system power source as a main power source for the function unit5, while using the power generation unit3as a backup power source in case of power outage.

As described above, the function unit5of the portable facility1includes an electric apparatus11which is powered by the power generation unit3to operate. A plurality of electric apparatuses11having different functions may be disposed inside the second housing H2of the function unit5. When the function unit5is constituted as a mobile shop (or a mobile store), for example, the function unit may include a lighting apparatus for illuminating the interior of the second housing H2, a refrigerator, and a cash register as the electric apparatuses11.

The function unit5of the portable facility1having the above construction can be used as, for example, a shop for selling food and/or convenience goods in a depopulated area. Further, the function unit5of the portable facility1can be constituted as a unit having various functions as described later to be used as a shop for other applications than selling goods. Furthermore, the portable facility1according to the present embodiment may include a plurality of function units5for a single power generation unit3. In such a case, the respective function units5may have a same function or different functions.

In the present embodiment, the power generation unit3includes a storage battery37and a control device39inside the first housing H1. As shown inFIG.3, the storage battery37stores electric power P1generated by the wind power generation device7and the solar power generation device9and supplies the stored electric power P2to the electric apparatus11of the function unit5as needed. The control device39controls an input of the electric power P1generated by the power generation devices7,9to the storage battery37and an output of the electric power P2from the storage battery37to the function unit5(electric apparatus11). For example, the control device39includes an AC/DC converter for converting alternating current (AC) electric power generated by the power generation devices7,9into electric power having a voltage which can be stored in the storage battery37as well as an inverter for converting the electric power stored in the storage battery37into sine wave AC similar to commercial AC power or into square wave AC.

The control device39may further include: a power generation monitoring section for monitoring a power generation amount of each power generation device7,9in the power generation unit3; a power consumption monitoring section for monitoring a power consumption amount of each electric apparatus11in the function unit5; a storage battery monitoring section for monitoring a residual capacity of the storage battery37; an operation estimating section for estimating an operable time of the function unit5on the basis of power generation amount data D1, power consumption amount data D2, and residual capacity data D3obtained by these monitoring sections; and an operable time displaying section for displaying the operable time estimated by the operation estimating section. Where a plurality of function units5are provided for a single power generation unit3as described above, the control device39of the power generation unit3may be capable of adjusting proportions of power supplies to the respective function units5as needed.

The following describes examples of the functions and applications of the function unit5of the portable facility1. The functions and applications of the function unit5of the portable facility1, however, are not limited to these examples.

When a natural disaster (such as earthquakes and floods) occurs, the portable facility1may be transported to an affected area and serve as food service equipment including electric apparatuses11such as a water purification device, a kitchen appliance, and a cooking device in the function unit5. In such a case, electricity generated in the power generation unit3may be used to supply power to a lighting in that area, to charge a mobile device, or to power a disaster relief device such as the water purification device.

Similarly, when a natural disaster occurs, the portable facility1may be transported to an affected area and serve as housing equipment (temporary dwelling) including electric apparatuses11necessary for daily life such as a lighting device, a water purification device, a cooking device, and an air conditioning device in the function unit5.

When a temporary railroad station is opened during a tourist season, the portable facility1including an automatic ticket gate as an electric apparatus11in the function unit5may be transported to and set up in the temporary station.

The portable facility1including a desk, a chair, a personal computer, a projector, a monitor, or the like in the function unit5may be used as a meeting room or a study room.

It should be noted that the function of the function unit5which is set at the time of setting up the portable facility1may be changed depending on the needs in the area of demand later on. That is, the function of the function unit5can be changed by suitably changing various electric apparatuses11disposed inside the function unit5and/or other accessories.

The portable facility1according to the present embodiment can be separated into the power generation unit3and the function unit5so as to be easily transported by logistics or transportation equipments such as automobiles, railroad cars, ships, and airplanes. Where they are transported by transportation equipments other than automobiles (i.e. railroad cars, ships, airplanes, or the like), the power generation unit3and the function unit5may be transported to a railroad station, a port, or an airport located near an installation site of the facility, and then be transported by an automobile to the installation site of the facility. In a case where the respective units are transported by an automobile, for example, the automobile is a unic vehicle UV (crane truck) as shown inFIG.4. After the respective units3,5is transported by a unic vehicle UV to an installation site, the respective units are unloaded from the vehicle by a crane of the unic vehicle UV. The operation of unloading the respective units of the portable facility1from different transportation equipments may be carried out by using a forklift or a gantry crane.

Next, a portable facility1according to another embodiment of the present invention will be described. This embodiment is the same as the embodiment shown inFIG.1except that when the first housing H1of the power generation unit3is a freight container, and the power generation unit3includes a solar power generation device9, the solar power generation device9is attached to the first housing H1in a different manner. Therefore, the following description will only describe how the solar power generation device9is attached to the first housing H1with reference toFIG.5toFIG.22, and description of other features will be omitted.

As shown inFIG.5andFIG.22, the solar power generation device9according to the present embodiment includes a plurality of (eight in this example) solar panels33which can be accommodated in the first housing H1, which is a freight container, and are configured to be disposed on the upper side15aof the top wall15, which is a roof of the first housing H1, to perform solar power generation. That is, the solar power generation device9is constituted as a container-accommodated mobile power generation device.

As shown inFIG.9,FIG.10andFIG.12, in each solar panel33, the rollers55aat the frontward positions in the movement direction and the large-diameter rollers55bare guided inside the rail grooves Rm of the internal rails59, and the rollers55cat the rearward positions in the movement direction are guided along outer surfaces of one flanges Fg of the respective internal rails59which are located in lower sides of the internal rails.

Connecting Rail Member

As shown inFIG.11toFIG.13, the connecting rail members60are so-called retrofit rail members for connecting the external rails57and the internal rails59with the doors53of the first housing H1opened, and are provided in a connection-releasable manner. For example, each connecting rail member60may be detachably coupled to attachment metal fittings56,58located above and below. Alternatively, each connecting rail member may be detachably coupled to an external rail57and an internal rail59located above and below.

FIG.12is an enlarged view of part XII ofFIG.11.FIG.13Ais a front view of a connecting rail member60as viewed from the side of the rail groove Rm, andFIG.13Bis an end view along line XIIIB-XIIIB ofFIG.13A. As shown inFIG.12andFIG.13A, each connecting rail member60has a groove-shaped cross section so as to define a rail groove Rm therein and includes a web Wb and flanges Fg, Fg extending in a bending manner from opposite edge portions of the web Wb so as to define the rail groove Rm. The connecting rail member60is constituted by channel steel or the like. For example, the connecting rail member60can be easily produced by fixing three pieces of channel steel by welding or the like. The connecting rail members60are arranged in pairs such that opened surfaces of the rail grooves Rm of each pair face each other, and the pluralities of rollers55(FIG.10) attached in pairs to the two sides of each solar panel33are guided in the facing rail grooves Rm, Rm.

Each connecting rail member60includes an upper rail part60ahaving a rail groove Rm to be connected to a rail groove Rm of a corresponding external rail57(FIG.8), a lower rail part60bhaving a rail groove Rm to be connected to a rail groove Rm of a corresponding internal rail59(FIG.9), and a middle rail part60chaving a rail groove Rm connected to tip end portions of the rail grooves Rm of these rail parts60a,60b.

Of the plurality of rollers55, the rollers55aat the frontward positions in the movement direction are guided into the rail grooves Rm of the lower rail parts60b. Each middle rail part60chas a cutout62formed in a lower portion of one flange Fg of that middle rail part which is located outside, and the cutout62allows a roller55aat the frontward position in the movement direction to exit the rail groove Rm of that middle rail part, so that a posture of the solar panel33can be changed. As shown inFIG.13AandFIG.19, of the plurality of rollers55, the rollers55cat the rearward positions in the movement direction are guided into the rail grooves Rm of the upper rail parts60a. Each middle rail part60chas a cutout61formed in an upper portion of one flange Fg of that middle rail part which is located outside, and the cutout61allows a roller55cat the rearward position in the movement direction to be inserted into the rail groove Rm of that middle rail part. The respective cutouts61,62are formed as rectangular holes and are sized so as to allow the small-diameter rollers55a,55cto exit and be inserted but not to allow the large-diameter roller55b(FIG.11) to exit.

Placement Procedure of Solar Panel

Next, a procedure for placing the solar panels33on the upper side15aof the top wall15, which is a roof of the first housing H1(i.e., freight container), will be described. The following process may be performed using human effort, or using a machine such as a motor, or in automated operation. Of course, the solar panels33may be placed using a motor or the like.

As shown inFIG.10toFIG.12, with the doors53of the first housing H1opened, the external rails57and the internal rails59are connected by the connecting rail members60. Next, a solar panel33supported by the internal rails59is guided and moved by the rollers55sequentially through the internal rails59and the connecting rail members60. Then, as shown inFIG.12toFIG.14, the small-diameter rollers55aat the frontward positions in the movement direction are brought out from the cutouts62in the lower portions of the connecting rail members60.

When the small-diameter rollers55aare brought out, the large-diameter rollers55bin the middle are not brought out from the cutouts62, so that the posture of the solar panel33is changed to a desired angle around the large-diameter rollers55bas fulcra to raise up the solar panel as shown inFIG.15. Next, as shown inFIG.16, the large-diameter rollers55bare moved into the connecting rail members60, and the solar panel33is brought up to the upper side15aof the top wall15(FIG.17). Then, as shown inFIG.18andFIG.19, the small-diameter rollers55cat the rearward positions in the movement direction are inserted into the connecting rail members60from the cutouts61in the upper portions of the connecting rail members60.

Then, as shown inFIG.20, the respective rollers55are guided along the external rails57, and the solar panel33is moved to a predetermined position. In this case, a stopper member63for restricting movement of the solar panel33is provided at an end of each external rail57, and the stopper member63prevents the solar panel33from moving out of the external rail57. As shown inFIG.21, the same process is repeated to place a second solar panel33on the upper side15aof the top wall15in every row, and the connecting rail members are removed.FIG.22shows a final configuration in which eight solar panels33in total are placed on the upper side15aof the top wall15.

Such a constitution makes it possible to facilitate a deployment operation of the solar panels33on site and to shorten a time required to place the solar panels33. When the solar panels33are attached in advance to the metal fittings which serves as mounts for the panels, and wiring for the panels is completed before placement of the solar panels33, it is only necessary to connect a connector to a non-illustrated connection box to generate electricity by solar power generation. The electricity generated by solar power generation is applied to a non-illustrated controller to be stored in the storage battery or is supplied to power a load device which requires electricity, such as a lighting device or communication equipment.

Effects and Advantages

According to the container-accommodated mobile power generation device as described above, the connecting rail members60for connecting the external rails57and the internal rails59with the doors53of the first housing H1(i.e., freight container) opened are provided in a connection-releasable manner, so that the first housing H1can be transported with the connecting rail members60removed from the external rails57and the internal rails59to release the connections and with the doors53of the first housing H1closed. When the first housing H1is transported, the first housing H1can be easily transported to an area of demand with the solar panels33supported by the internal rails59which are supported by the top wall15inside the first housing H1. Since the solar panels33are housed in the first housing H1during transport of the first housing H1, the solar panels33are not subjected to impact from outside and thus can be easily transported.

When solar panels33are to be placed on the upper side15aof the top wall15, which is a roof of the first housing H1, the connecting rail members60are placed to connect the external rails57and the internal rails59with the doors53of the first housing H1opened. Thus, the solar panels33are guided and moved by the rollers55from the internal rails59sequentially to the connecting rail members60and then to the external rails57, so that the solar panels are easily placed on the upper side15aof the top wall15of the first housing H1. This makes it possible to facilitate a deployment operation of the solar panels33on site and to shorten a time required to place them. In a reverse procedure to the above-described procedure, the solar panels33can be easily received into the first housing H1, which is a freight container.

Further Embodiments

In the following description, the same reference numerals are used to denote parts that correspond to those previously described in the respective embodiments, and overlapping description is omitted. Where only a part of a configuration is described, the rest of the configuration is to be construed as being the same as the previously described embodiments unless otherwise indicated. The same configurations provide the same effects. It is possible not only to combine the parts that have been particularly described in the respective embodiments but also to partly combine the embodiments unless there is any hindrance to such a combination.

As shown inFIG.23, each connecting rail member60A may be formed in a circular arc shape. In this case, the pluralities of rollers55attached to the solar panels33can be smoothly and speedily guided along the connecting rail members60A having the circular arc shape. In this case, it is not necessary to provide the cutouts or the like which allow the rollers55to be inserted into or exit the connecting rail members60A, and it is not necessary to form the rollers55having large and small diameters to differentiate them, so that all the rollers can be constituted by rollers having a same configuration. Thus, the cost of the entire apparatus can be reduced.

As shown inFIG.24, one or both of the wind power generation device7and the hydraulic power generation device65may be housed in the first housing H1(i.e., freight container) which houses the solar panels33(solar power generation device9). In this case, transport efficiency can be improved as compared to a case where the wind power generation device7and the hydraulic power generation device65are housed in another container or the like to be transported. This constitution is also advantageous in securing electric power.

The freight container constituting the first housing H1is not limited to a 12-ft container and may be, for example, a container meeting an ISO standard for 20-ft dry containers, 40-ft dry containers, 45-ft dry containers, or the like.

As described above, according to the portable facility1of the present embodiment, the respective housings H are capable of being transported, so that the portable facility has high transportability. Further, since the power generation unit3includes a natural energy power generation device such as the wind power generation device7, the solar power generation device9, and/or the hydraulic power generation device, it is possible to use the electric apparatus11even in areas where it is difficult to secure power supply such as unelectrified areas and disaster areas, so that the facility1can be more easily operated. In particular, where the facility includes all of the wind power generation device7, the solar power generation device9, and the hydraulic power generation device, the power generation amount is less likely to be limited by natural environment such as weather conditions and topographical features, and/or time of the day or night, so that the facility1can be set up and be operated with a greater applicability to a wide range of areas.

According to the container-accommodated mobile power generation device of the application configuration, the following effects can also be obtained. Since the connecting rail member for connecting the external rail and the internal rail with the door of the freight container opened is provided in a connection-releasable manner, the container can be transported with the connecting rail member removed from the external rail and the internal rail to release the connection and with the door of the container closed. When the container is transported, the container can be easily transported to an area of demand with the solar panel supported by the internal rail disposed on a ceiling inside the container. Since the solar panel is housed in the container during transport of the container, the solar panel is not subjected to impact from outside and thus can be easily transported.
