Patent Description:
Along with the increase of awareness of environmental protection, those pollution-free green energies such as solar energy and wind power have been widely applied to various fields in modern life. A conventional solar photovoltaic device is capable of converting sunlight into electrical energy. In general, the solar photovoltaic device has multiple solar panels securely arranged in predetermined positions directed to the sun for maximally receiving sunlight. For lowering the cost for setting up these solar panels, the solar panels generally are not equipped with any movable mechanism so that the solar panels cannot be moved as necessary. As a result, the existing solar photovoltaic device can hardly achieve optimal power generation efficiency to meet the principle of economical benefit. In order to increase the power generation capability of the solar photovoltaic device, generally the number of the solar panels and the sunshine area of the solar photovoltaic device are increased. In practice, the solar panels are fixed panels for receiving sunshine. In this case, the fixed panels will block the sunlight from a great area of ground and space under the solar panels. Due to long-term lack in sunshine, the ground under the solar panels can be hardly utilized for farming, planting or culture. This leads to waste of land resource.

<CIT> discloses a green artistic pavilion. The pavilion has a solar roof, (that is, a solar panel), and a wind-driven power generation device for generating power to provide necessary electrical energy for illumination device of the pavilion. In such structure, the solar roof and the wind-driven power generation device respectively operate to generate power. A controller disposed in a battery device serves to integrate and store the electrical energy.

<CIT> discloses a hybrid solar wind power generation cabinet with vehicle speed alert function. The hybrid solar wind power generation cabinet has a cabinet main body, in which a wind-driven power generation module and a speed alerter are disposed. In addition, a solar panel is disposed on outer side of the cabinet main body. The solar panel and the wind-driven power generation device complementarily generate power to provide necessary electrical energy for the speed alerter. In addition, according to the change of the power generation capability of the wind-driven power generation module, the speed alerter can judge the moving speed of the cabinet main body. In such structure, the solar panel and the wind-driven power generation module also respectively operate to generate power and a power control module is used to integrate and store the electrical energy.

In addition, <CIT> discloses a hybrid solar wind power generation device. The hybrid solar wind power generation device includes a wind-driven power generation assembly and a solar panel connected therewith. The wind-driven power generation assembly is drivable by wind to drive a power generation unit to generate power. The solar panel serves to cooperatively convert solar energy into electrical energy. In such structure, the solar panel and the wind-driven power generation assembly also respectively operate to generate power. The wind-driven power generation assembly serves to drive the power generation unit to generate power, while the solar panel directly converts sunlight into electrical energy (without driving the power generation unit to generate power). Then all the electrical energy (generated by the power generation unit and the solar panel) is integrated and stored for successive reuse.

<CIT> is another relevant example of prior art.

In practical application of the above conventional structures, the electrical energy converted from the sunlight by the solar panel and the electrical energy generated by the power generator driven by the wind-driven power generation assembly (the wind-driven power generation module) respectively have different voltaic specifications and current properties. Therefore, it is necessary to further use a power control module (or controller) to integrate the electrical energy so as to meet the requirement for reuse or storage. The complicated electronic circuit structure of such power control module (or controller) not only increases the cost for setting up the entire device, but also leads to increase of possibility of failure. Therefore, the above conventional hybrid solar wind power generation devices have many shortcomings in application.

It is therefore tried by the applicant to provide a hybrid solar wind power generation device to eliminate the shortcomings of the conventional hybrid solar wind power generation devices in practical application.

It is therefore a primary object of the present invention to provide a hybrid solar wind power generation device, which includes at least one wind-driven module and at least one solar module drivingly connected with a drive shaft of one single preset power generator. The wind-driven module is drivable by external wind power to drive the drive shaft to rotate for making the power generator generate power. The solar module has a solar panel set and a motor. The solar panel set has multiple solar panels arranged at intervals and multiple hollow sections defined between the solar panels. The solar panel set serves to convert sunlight into electrical energy to drive the motor for driving the solar panel set and the drive shaft to rotate so as to make the power generator generate power. During the process of power generation, both the wind-driven module and the solar module are continuously rotated along with the drive shaft. Therefore, sunlight can intermittently pass through the hollow sections between the wind-driven module and the solar panels in rotation and project onto the ground (or the space under the wind-driven module and the solar module) for sunshine or illumination. Therefore, the sunlight is prevented from being blocked from the ground or the space under the wind-driven module and the solar module, whereby the ground or the space can be still utilized for farming, planting or culture without wasting land resource.

It is a further object of the present invention to provide the above hybrid solar wind power generation device, in which both the wind-driven module and the solar module serve to drive the drive shaft for driving the power generator to generate necessary power. Therefore, in the entire structure, it is unnecessary to use any power control module for integrating different voltaic specifications and current properties. This not only lowers the cost for setting up the entire mechanism, but also minimizes the possibility of failure of the mechanism. Therefore, the quality of the product is enhanced.

It is still a further object of the present invention to provide the above hybrid solar wind power generation device, in which an assembly of multiple wind-driven modules and multiple solar modules is disposed on the drive shaft of one single power generator so as to satisfy the necessary drive power requirement of various application environments or power generator sets. In addition, a transmission gear set can be connected between the power generator and the drive shaft so as to change the rotational speed of the drive shaft into a proper rotational speed for properly driving the power generator to generate power.

It is still a further object of the present invention to provide the above hybrid solar wind power generation device, in which the wind-driven modules, the solar modules and the power generators are disposed on a seat body. The width and structure of the seat body are varied with the volume and size of the wind-driven modules and the solar modules. Accordingly, the seat body has a minimal shade ratio so as to provide better sunlight penetration effect. In addition, the seat body can be designed with different forms and structures in accordance with the numbers of the wind-driven module, the solar modules and the power generators so as to satisfy different power generation requirements of different sites.

The present invention can be best understood through the following description and accompanying drawings, wherein:.

Please refer to <FIG>. According to a first embodiment of the present invention, the hybrid solar wind power generation device of the present invention includes a power generator <NUM>, a wind-driven module <NUM> and a solar module <NUM>. The power generator <NUM> is connected with a drive shaft <NUM>, which is drivable by external force. As necessary, a transmission gear set (not shown) can be further connected between the power generator <NUM> and the drive shaft <NUM>, whereby the rotational speed of the drive shaft <NUM> can be changed into a proper rotational speed for driving an internal mechanism of the power generator <NUM> to generate power. In practice, two power generators <NUM> can be alternatively respectively assembled with two ends of the drive shaft <NUM> to vary the application for satisfying different power generation requirements of different sites and enhancing the power generation performance as a whole.

The wind-driven module <NUM> is connected with the drive shaft <NUM> (directly or via a connection member) and disposed between the drive shaft <NUM> and a solar panel set <NUM> of the solar module <NUM>. The wind-driven module <NUM> is drivable by external wind power to rotate the drive shaft <NUM> for driving the power generator <NUM> to generate power. In a preferred embodiment, the wind-driven module <NUM> has a wind-driven blade set <NUM> disposed around the drive shaft <NUM> (as shown in <FIG>).

As shown in the drawings, the wind-driven blade set <NUM> is composed of multiple wind-driven blades <NUM> each having an arcuate cross section. Inner edges of the wind-driven blades <NUM> are adjacent to or connected with the drive shaft <NUM>, while outer edges of the wind-driven blades <NUM> are positioned at equal intervals and extend in an axial direction of the drive shaft <NUM> in parallel to each other.

The solar module <NUM> has the solar panel set <NUM>, which is rotatable with the drive shaft <NUM> and connected with a motor <NUM> of the drive shaft <NUM> (directly or via a connection member). The solar panel set <NUM> has multiple solar panels <NUM> arranged at intervals. Multiple hollow sections <NUM> are defined between the solar panels <NUM> for sunlight to pass through. The solar panel set <NUM> serves to convert sunlight into electrical energy for driving the motor <NUM> to drive the solar panel set <NUM> and the drive shaft <NUM> to rotate. When the drive shaft <NUM> rotates, the drive shaft <NUM> drives the power generator <NUM> to generate power. Also, during the rotation of the solar panel set <NUM>, the sunlight can intermittently pass through the hollow sections <NUM> to project onto the ground or space under the solar panel set <NUM> and the wind-driven blade set <NUM> for sunshine or illumination.

In a preferred embodiment, the drive shaft <NUM> can be connected with a support assembly <NUM> as necessary. The support assembly <NUM> has two movable seats <NUM> secured on the drive shaft <NUM> at an interval (and rotatable with the drive shaft <NUM>). Two fixed seats <NUM> are coaxially disposed beside the movable seats <NUM>. The movable seats <NUM> are rotatable relative to the fixed seats <NUM>. In addition, multiple grid supports <NUM> are disposed between the two movable seats <NUM> at equal intervals. The grid supports <NUM> are annularly arranged and centered at the axis of the drive shaft <NUM>. As necessary, the grid supports <NUM> can extend linearly or be curved. In the case that the grid supports <NUM> are curved, two end sections of the grid supports <NUM> can be respectively connected with outer circumferences of the two movable seats <NUM> and positioned around the drive shaft <NUM>. The solar panels <NUM> are flexible (soft) solar panels (sheets) attached to outer faces of the grid supports <NUM>, whereby the hollow sections <NUM> are naturally formed between the solar panels <NUM> (grid supports <NUM>). The solar panel set <NUM> can surround the wind-driven blade set <NUM>. Alternatively, each grid support <NUM> has a wind-driven blade <NUM> extending from the grid support <NUM> to the drive shaft <NUM> (as shown in <FIG> and <FIG>). The wind-driven blade <NUM> is disposed in a position in adjacency to a back face of the solar panel <NUM> (such as a back face of the grid support <NUM>). The wind-driven blades <NUM> are also coaxially and synchronously rotatable with the solar panel set <NUM>.

In this embodiment, the power generator <NUM>, the wind-driven module <NUM> and the solar module <NUM> are assembled on a seat body <NUM>. The seat body <NUM> has two support sections <NUM> respectively connected with the two fixed seats <NUM>. The power generator <NUM> is disposed on an outer side of at least one of the support sections <NUM>. The wind-driven module <NUM> and the solar module <NUM> are disposed between the two support sections <NUM>. The motor <NUM> has multiple magnetic bodies <NUM> arranged in the fixed seats <NUM> and multiple winding members <NUM> arranged in the movable seats <NUM> corresponding to the magnetic bodies <NUM> respectively. A drive circuit (not shown) is used to drive the respective winding members <NUM> to generate interactive magnetic force effect relative to the magnetic bodies <NUM>, whereby the drive shaft <NUM> is driven as a brushless direct current (BLDC) motor. Accordingly, the drive shaft <NUM> can be pivotally rotated relative to the fixed seats <NUM> (as the power generator <NUM>). However, in practice, the winding members <NUM> and the magnetic bodies <NUM> of the motor <NUM> can be alternatively designed with different forms of various other motors so as to provide different driving means for driving the drive shaft <NUM> to rotate.

In practice, the width and structural design of the seat body <NUM> are varied with the volume and size of the wind-driven module <NUM> and the solar module <NUM>. The seat body <NUM> has a minimal shade ratio so as not to unnecessarily block the sunlight passing through the wind-driven module <NUM> and the solar module <NUM>.

In practical operation of the above structure, when air convection takes place in the external environment, the wind power can directly push the wind-driven blade set <NUM> of the wind-driven module <NUM>, whereby the drive shaft <NUM> and the solar panel set <NUM> synchronously or asynchronously drivingly rotate. At this time, the drive shaft <NUM> drives the power generator <NUM> to generate power. In an environment with sunshine, the solar panel set <NUM> of the solar module <NUM> receives sunlight to generate electrical energy for driving the motor <NUM> to drive the solar panel set <NUM> and the drive shaft <NUM> to rotate. Accordingly, the power generator <NUM> is further driven to generate power. During the above process of power generation, the wind-driven blade set <NUM> of the wind-driven module <NUM> and the solar panel set <NUM> of the solar module <NUM> are both rotated along with the drive shaft <NUM>. Therefore, the sunlight can intermittently pass through the hollow sections <NUM> between the solar panels <NUM> by different angles and project onto the ground under the hollow sections <NUM> (or the space under the solar panel set <NUM> and the wind-driven blade set <NUM>) for sunshine or illumination. Accordingly, the space or the ground under the solar panel set <NUM> and the wind-driven blade set <NUM> can utilize the sunshine to keep the operation of farming, planting or culture without wasting land resource. Moreover, in an environment lacking wind power or sunlight, the solar panel set <NUM> and the wind-driven blade set <NUM> are drivingly connected with each other and complementary to each other so as to keep rotating for generating power without shading sunlight. Therefore, the wind power and the solar energy are complementary and assistant to each other to keep operating for generating power.

Please refer to <FIG>. According to a second embodiment of the present invention, the hybrid solar wind power generation device of the present invention includes a power generator <NUM>, a wind-driven module <NUM> and a solar module <NUM>, which are identical to those of the first embodiment and further includes a transverse seat body 4a. The seat body 4a has multiple vertical support sections 41a arranged at intervals. The power generator <NUM> is disposed on an outer side of a support section 41a of at least one end section of the seat body 4a. An assembly of multiple wind-driven blade sets <NUM> of multiple wind-driven modules <NUM> and multiple solar panel sets <NUM> of multiple solar modules <NUM> is arranged between the support sections 41a and supported thereby. The multiple wind-driven blade sets <NUM> and the multiple solar panel sets <NUM> are disposed on one single drive shaft <NUM> to apply greater driving force to the drive shaft <NUM> for driving the power generator <NUM> to generate power. Accordingly, the application of the hybrid solar wind power generation device of the present invention is variable.

Please refer to <FIG>. According to a third embodiment of the present invention, the hybrid solar wind power generation device of the present invention includes a power generator <NUM>, a wind-driven module <NUM> and a solar module <NUM>, which are identical to those of the first embodiment and further includes a vertical seat body 4b. The seat body 4b has multiple checker-like support sections 41b. The power generator <NUM> is disposed on a lateral (outer) side of a support section 41b of each of upper and lower ends of the seat body 4b. In addition, multiple leg sections 42b downward protrude from the seat body 4b to support and keep the power generator <NUM> under the seat body 4b at a proper height or in a proper position so as to avoid damage of the power generator <NUM> due to compression or collision.

An assembly of multiple wind-driven blade sets <NUM> and multiple solar panel sets <NUM> is supported between the checker-like support sections 41b. In addition, the assembly of the wind-driven blade sets <NUM> and the solar panel sets <NUM> is vertically arranged and disposed on one single vertical drive shaft <NUM>. Accordingly, the multiple vertically arranged wind-driven blade sets <NUM> and the multiple vertically arranged solar panel sets <NUM> together form a large-scale vertical hybrid solar wind power generator set, in which the multiple wind-driven blade sets <NUM> and the multiple solar panel sets <NUM> drive the drive shafts <NUM> for driving the power generators <NUM> on the upper and lower sides (or in adjacency to each other) to operate and generate power. Accordingly, the application of the hybrid solar wind power generation device of the present invention is variable. In conclusion, the hybrid solar wind power generation device of the present invention can truly respectively utilize wind power and solar energy to drive the power generator. Moreover, in operation, the sunlight can intermittently downward pass through the wind-driven blade set and the solar panel set to project onto the ground thereunder. The hybrid solar wind power generation device of the present invention is inventive and advanced and the application range of the hybrid solar wind power generation device of the present invention is widened.
