DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Description of some embodiments of the present invention will be given below with reference to drawings. It should be noted that the illustration of the drawings are merely for the purpose of describing, and is not intended to limit the scope of the present invention.

In this disclosure, the term “coupled” may mean “directly coupled” or “indirectly coupled”. “Coupled” may further refer to the interoperation or interaction between two or more elements.

The arrangement of a system for providing dynamic force of an embodiment of the present invention is as shown inFIG.1. Refer toFIG.1, in one embodiment, the engine110operates as the source of dynamic force in the system for providing dynamic force100. The dynamic force generated by the engine110is transmitted to first motor141and second motor142through gear box120, first clutch131, and second clutch132, so as to drive the first motor141and the second motor142. As shown inFIG.1, the system for providing dynamic force100drives the first one-way fly wheel151and the second one-way fly wheel152by the first motor141and second motor142, so as to provide dynamic force through the rotation of the first one-way fly wheel151and the second one-way fly wheel152. In one embodiment, the engine110may be a diesel engine.

The description above is merely exemplary, and is not intended to limit the features of the present invention. For example, in this embodiment, the gear box120, the first clutch131and the second clutch132compose a transmission module1230that can control the first motor141and the second motor142to be driven by the dynamic force of the engine110, wherein the first clutch131and the second clutch132is disposed at a first output terminal and a second output terminal of the gear box120respectively. In other embodiments, a transmission module having an input terminal and a plurality of output terminals could be composed of other components. For example, in one embodiment, a transmission module may be composed of a flat belt drive mechanism and a plurality of clutches. In another embodiment, a transmission module may be composed of a chain drive mechanism and a plurality of clutches. In addition, the present invention is not limited to the arrangement of transmission module1230shown inFIG.1. For example, in another embodiment, the first clutch131and the second clutch132may be disposed inside the gear box120. It should be noted that in the embodiments described above, the transmission module1230comprises two output terminals, but the present invention is not limited thereto. In other embodiments, the transmission module may comprise any number of output terminals.

Refer toFIG.2, in another embodiment of the present invention, the transmission module2230may be composed of the bevel gear2231, the bevel gear2232, the clutch131, the bevel gear2233, and the clutch132. As shown inFIG.2, the transmission module2330has an input terminal (i.e. the shaft of the bevel gear2331), a first output terminal (i.e. the shaft of bevel gear2232) and a second output terminal (i.e. the shaft of the bevel gear2233), the input terminal may be connected to the engine110, the output terminals may be connected to two motors (not illustrated inFIG.2), and the transmission module2230may control the output terminals to drive the motors respectively through clutch131and clutch132.

In this embodiment, the gear box120has an input terminal and two output terminals, the input terminal of the transmission module1230is the input shaft of the gear box120. The two output terminals of the transmission module1230are the two output terminals of the gear box120. Moreover, in this embodiment, the transmission module1230comprises the first clutch131and the second clutch132. Accordingly, the first clutch131and the second clutch132can be used to control the dynamic force generated by the output shaft of the gear box120to be transmitted to the first motor141and the second motor142.

In this embodiment, due to the structure of one-way flywheel, when the rotational speed of the first motor141and the second motor142decreases or when the first motor141and the second motor142stop rotating, the first one-way fly wheel151and the second one-way fly wheel152may maintain their rotational inertia, so the reduction of the rotational speed of the first one-way fly wheel151and the second one-way fly wheel152is slower (in other words, compared with flywheels that can spin in two ways, the duration of one-way fly wheels in high rotational speed is longer). Accordingly, the efficiency of the provision of dynamic force may be improved. In another embodiment, the same effect may be achieved replacing one-way fly wheel with ratchet. As shown inFIG.1, the system for providing dynamic force100also comprises the solar panel170and the electrical energy storage device180. The arrows illustrated inFIG.1represent the power supply relationships between devices/components. In this embodiment, the solar panel170is electrically connected to the electrical energy storage device180, the first motor141, and the second motor142. The electrical energy storage device180is electrically connected to the first motor141and the second motor142. The electrical energy storage device180stores the electrical energy generated by the solar panel170. The first motor141and the second motor142are not electrically connected to each other. The contents of the Figures are merely exemplary, so the dimensions and proportions of each of the components/elements may not necessarily match the actual dimensions and proportions.

In this embodiment, the first motor141and the second motor142may be respectively driven by the engine110and the transmission module1230. The first motor141and the second motor142may also be respectively driven by the solar panel170and/or the electrical energy storage device180. For example, in some scenarios, the engine110may rotate at a speed in the range of 150-250 rpm, and drive the first motor141and the second motor142to rotate at the same speed, and the rotational speed of first motor141and the second motor142may reach 850-1000 rpm when driven by the solar cell170or the electrical energy storage device180. Accordingly, in these scenarios, the first motor141and the second motor142may be respectively driven by the engine110and the transmission module1230when there is no need for the first motor141and the second motor142to be rotating at a high rotational speed; while the first motor141and the second motor142may be respectively driven by the solar panel170or the electrical energy storage device180to increase the rotational speed of the first motor141and the second motor142when there is a need for the first motor141and the second motor142to be rotating at a high rotational speed. Moreover, in this embodiment, because the first motor141and the second motor142are driven respectively, various speeds may be provided for various needs. For example, the first motor141may be driven to rotate at a rotational speed of 850 rpm, while at the same time the second motor142may be driven to rotate at a rotational speed of 1000 rpm. The values of rotational speed are merely exemplary and is not intended to limit the present invention. In other scenarios, the first motor141and the second motor142may be driven to rotate at any rotational speed(s) of different or same value(s) to each other.

It should be noted that in this embodiment, the system for providing dynamic force100comprises a solar panel170, but the present invention is not limited thereto, in other embodiments, the system for providing dynamic force100may comprise a plurality of solar panels.

The system for providing dynamic force100of this embodiment comprises a plurality of motors, so dynamic force may be provided flexibly. Moreover, the arrangement of a plurality of motors may increase the stability of provision of dynamic force, details will be described below.

FIG.3illustrates the system for providing dynamic force200of another embodiment of the present invention. Refer toFIG.3, in this embodiment, the solar panel170of the system for providing dynamic force200is disposed on top of the sound insulation container190, other devices/components of the system for providing dynamic force200are disposed inside the sound insulation container190. As shown inFIG.3, the sound insulation container190comprise a roll-up door191to provide convenient access to the system for providing dynamic force200.

FIG.4illustrates a cross-sectional view taken along line A-A ofFIG.3. Refer toFIG.4, in this embodiment, the arrangement of the system for providing dynamic force200is substantially the same as the arrangement of the system for providing dynamic force100illustrated inFIG.1, but the system for providing dynamic force200of this embodiment comprises four electrical energy storage devices181-184. Moreover, the first one-way fly wheel151drives the pump161, and the second one-way fly wheel152drives the generator162.

The description above is merely exemplary and is not intended to limit the scope of the present invention. For example, in other embodiments, the system for providing dynamic force of the present invention may drive two pumps or two generators. Or, depending on the needs, the system for providing dynamic force of the present invention may comprise a larger number of terminals (e.g. the gear box120may comprise a larger number of output shafts) to drive more motors and in turn drive more pumps or generators. For example, in some embodiments the system for providing dynamic force may comprise a terminal that drives a pump for aeration, a terminal that drives another pump for fire fighting, and one or more terminals that drive one or more generators. Moreover, in other embodiments, the system for providing dynamic force of the present invention may comprise different numbers of electrical energy storage devices.

Refer toFIG.3andFIG.4, in this embodiment, aside from storing electrical energy generated by the solar panel170, the electrical energy storage devices181-184may also store electrical energy generated by the generator162(the power supply relationships between the devices/components are not illustrated for the sake of conciseness). For example, in one scenario, the engine110may be operated to rotate at 150 rpm to drive the first one-way fly wheel151to provide dynamic force to the pump161, and drive the second one-way fly wheel152to provide dynamic force to the generator162. Electrical energy generated by the generator162and the solar panel170may be stored in the electrical energy storage devices181-184. When larger dynamic force is needed, the axes of the first motor141and the second motor142may be disconnected from output shaft(s) of the gear box120, and the first motor141and/or second motor142may be driven by the solar panel170and/or the electrical energy storage devices181-184instead to increase the rotational speed of the first motor141and/or the second motor142to 850-1000 rpm. In some embodiments where the first motor141and the second motor142are motors with one-way bearing, the first motor141and/or the second motor142need not to be disconnected from output shaft(s) of the gear box120by the first clutch131and the second clutch132when the first motor141and/or the second motor142is driven by the solar panel170and/or the electrical energy storage devices181-184. When there is no need for the first motor141and/or the second motor142to rotate at high rotational speed, the first motor141and/or the second motor142may stop being driven by electrical energy of the solar panel170and/or the electrical energy storage devices181-184, and the first motor141and/or the second motor142may be connected to output shaft(s) of the gear box120by the first clutch131and/or the second clutch132, so the rotational speed of the first motor141and/or the second motor142may fall back to 150 rpm. During the fall of the rotational speed, the first one-way fly wheel151and the second one-way fly wheel152will lose speed at a lower rate than the first motor141and the second motor142. Accordingly, during the fall of the rotational speed, the second one-way fly wheel152may keep driving the generator162at rotational speed higher than 150 rpm to generate electrical energy for the electrical energy storage devices181-184to store.

As described above, in this embodiment, dynamic force may be flexibly provided by each of the motors. For example, the system for providing dynamic force200may be used in aeration of culture pond. During regular times of aeration, the first motor141and the second motor142may be driven by the engine110through the transmission module1230, so as to drive the pump161to aerate a culture pond and drive the generator162to generate electrical energy for the electrical energy storage devices181-184to store. When there is need for the first motor141to rotate at a high rotational speed (e.g. when there is a need for fire fighting, the pump161may be used to provide water jets for fire fighting), the axis of the first motor141may be disconnected from a output shaft of the gear box120by the first clutch131, and the first motor141may instead be driven by the solar panel170and/or the electrical energy storage devices181-184, so as to increase the rotational speed of the first motor141. At the same time, the second motor142may still be driven by the engine110through the transmission module1230and keep driving the generator162to generate electrical power. Since the first motor141and the second motor142may rotate at different rotational speeds, the system for providing dynamic force of the present invention may satisfy different needs for dynamic force at one time. It should be noted that the needs given above are merely exemplary and are not intended to limit applications of the present invention. In another embodiment, the first motor141and the second motor142may drive two pumps respectively. With this arrangement, when there is a need for fire fighting and electrical energies of the solar panel170and the electrical energy storage devices181-184are not sufficient to drive the first motor141and the second motor142, the rotational speed of the engine may be increased, and the waterpipes of the two pumps may be connected to provide the amount of water required by a water jet.

In some embodiments, two one-way fly wheels of the system for providing dynamic force may be used to drive two pumps so as to contribute to stability of the provision of dynamic force. For example, if the system for providing dynamic force of these embodiments is applied in aeration of aquaculture pond, when one of the two pumps fails and requires maintenance or replacement, the other pump may remain in operation, so the aeration would not break off. Hence the stability and anti-risk capability of the system for providing dynamic force of the present invention. In these embodiments, during the replacement of the failed pump, and the axis of the failed motor may be disconnected from an output terminal of the gear box, and the engine may remain in operation, so the other motor may also remain in operation. Accordingly, maintenance of these embodiments is nimble.

FIG.5illustrates the flow chart of a method for providing dynamic force of one embodiment of the present invention. Refer toFIGS.3-5, in one embodiment, the method for providing dynamic force300shown inFIG.5may be carried out by the system for providing dynamic force200shown inFIGS.3-4.

In step S201, electrical energy generated by the solar panel170may be stored by the electrical energy storage devices181-184. In step S202, in a low rotation period where the need for dynamic force is low, the first motor141and the second motor142may be driven by the engine110through the transmission module1230. In step S203, in a high rotation period where the need for dynamic force is high, the first motor141and the second motor142may be driven by the solar panel170. In step S204, in the high rotation period, when the electrical energy generated by the solar panel170is not sufficient to drive the first motor141and the second motor142, the first motor141and the second motor142may be respectively driven by electrical energy generated by electrical energy storage devices181-184. In step S205, the first one-way fly wheel151and the second one-way fly wheel152may be respectively driven by the first motor141and the second motor142, so as to provide dynamic force with the first one-way fly wheel151and the second one-way fly wheel152.

It should be noted that the steps described above are merely exemplary. In other embodiments, the order of the steps may be altered. The method for providing dynamic force of the present invention is not limited to the order of steps described above.
