Description

Stream-type power generation device

The present invention relates to a hydroelectric power generation technology, and particularly to a stream-type power generation device.

With the increasing demand for green energy, more and more green energy power generation equipment has been developed. In particular, various types of power generation equipment for hydropower generation are currently widely discussed. However, traditional hydropower is nothing more than tidal, ocean current or river power. In this regard, since the construction cost of tidal power generation and ocean current power generation equipment is relatively high, and the construction range of tidal power generation and ocean current power generation equipment is large, it is easy to cause ecological pollution. Therefore, the tidal power generation and ocean current power generation methods are not practical and difficult Promotion. In addition, traditional river power generation uses horizontal or vertical blades to collect water flow to generate electricity. However, the traditional river power generation needs to be further provided with a deflector and a deflector, which seriously affects the amount of discharged water and easily destroys the ecology of the underwater biosphere. In view of this, how to propose a hydroelectric power generation device with good power generation efficiency, and can reduce the ecological damage to the aquatic biosphere and the image of the amount of water discharged, the solutions of several embodiments will be proposed below.

The invention provides a stream-type power generation device, which can effectively utilize the single direction characteristic of a river to generate electricity.

The stream-type power generation device of the present invention includes a power generation module and two movable mechanisms. The two movable mechanisms are arranged in the flowing water. The two movable mechanisms are connected to the power generation module via a cable. One of the two movable mechanisms is connected to one end of the cable, and the other of the two movable mechanisms is connected to the other end of the cable. When one of the two movable mechanisms is in the expanded mode and the other of the two movable mechanisms is in the collapsed mode, one of the two movable mechanisms follows the The water flow direction moves, and the other of the two movable mechanisms moves against the water flow direction, so that the power generation module obtains driving force through the cable to generate electricity.

In an embodiment of the present invention, the above two movable mechanisms are arranged in parallel in the flowing water area, and move linearly in opposite directions respectively.

In an embodiment of the invention, the above two movable mechanisms alternately switch between the expanded mode and the collapsed mode.

In an embodiment of the present invention, the above-mentioned power generation module includes a generator, a rotatable mechanism, and a speed increaser. The cable is sheathed on the rotatable mechanism. The speed increaser is coupled to the generator and is provided on the rotatable mechanism. When the two movable mechanisms are linked, the speed increaser provides the rotating power obtained by the rotatable mechanism via the cable to the generator to generate electricity.

In an embodiment of the invention, the above two movable mechanisms include a main board, two wings, two guide rails, and a deployment mechanism. The main board has a main board surface perpendicular to the direction of water flow. The two guide rails are provided on the upper and lower sides of the main board, so that the main board moves along the two guide rails. The two wings are swingably arranged on both sides of the main board. The unfolding mechanism is set on the main board, and the cable is connected. The deployment mechanism determines whether to fold or deploy the two wings according to the pulling force provided by the cable.

In an embodiment of the invention, the above two movable mechanisms each further include a main spring. The main spring is sheathed on the cable. One end of the main spring is arranged on the main board, and the other end is fixed to the cable. When the cable provides a pulling force greater than the elastic force of the main spring, the main spring stretches and provides a cushioning distance.

In an embodiment of the present invention, the above two movable mechanisms respectively further include a prop and a secondary spring. The top support member is inserted into the gap between the main board and the unfolding mechanism, and is connected with the cable. The secondary spring is sleeved on the top brace. One end of the secondary spring is pressed against the top supporting piece, and the other end is pressed against the main board. When the pulling force provided by the cable is greater than the elastic force of the primary spring, and the compression of the secondary spring displaces the prop, the deployment mechanism is loosened to swing and collapse the two wings.

In an embodiment of the present invention, when the pulling force provided by the above-mentioned cable is less than the elastic force of the main spring, the secondary spring returns to the prop, so that the deployment mechanism is clamped, and the two wings are swung and deployed .

In an embodiment of the present invention, each of the above-mentioned two unfolding mechanisms of the two movable mechanisms further includes two sliders that can reciprocally move relative to each other. The prop member penetrates or pulls away from the gap provided between the two sliders, so that the two sliders are away from or close to each other.

In an embodiment of the present invention, when the two wings of one of the above two movable mechanisms are swung to be deployed, one of the two movable mechanisms passes through the two The two wings receive the thrust of the flowing water to move in the direction of the water flow, and the two wings of the other of the two movable mechanisms simultaneously swing to collapse. The other of the two movable mechanisms moves against the direction of water flow according to the pulling force of the cable.

Based on the above, the stream-type power generation device of the present invention can be alternately switched between the expansion mode and the collapse mode by two movable mechanisms, so that the two movable mechanisms are pulled and displaced in the flowing water area to produce Driving force to the power generation module to generate electricity. Therefore, the stream-type power generation device of the present invention can provide good and stable power generation efficiency.

In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below and described in detail in conjunction with the accompanying drawings.

In order to make the content of the present invention easier to understand, the following specific embodiments are taken as examples on which the present invention can indeed be implemented. In addition, wherever possible, elements/components/steps using the same reference numbers in the drawings and embodiments represent the same or similar components.

FIG. 1 is a schematic top view of a stream-type power generation device according to an embodiment of the invention. Referring to FIG. 1, the stream power generation device 100 includes a power generation module 110 and two movable mechanisms 120 and 130. The movable mechanisms 120 and 130 are provided in the flowing water 200. In this embodiment, the movable mechanisms 120 and 130 are connected to the power generation module 110 via the cable 140, and are connected to each other via the cable 140. The movable mechanism 120 is connected to one end of the cable 140, and the movable mechanism 130 is connected to the other end of the cable 140. In this embodiment, the water flow WD of the flowing water area 200 fixedly flows in the direction of a single water flow, wherein the water flow WD of the flowing water area 200 may, for example, flow in the second direction P2. The first direction P1, the second direction P2, and the third direction P3 are perpendicular to each other. In the present embodiment, the movable mechanisms 120, 130 are arranged in parallel in the flowing water 200, and move linearly in opposite directions, respectively. The moving path of the movable mechanisms 120 and 130 may be parallel to the flowing water area 200 or the water flow WD of the flowing water area 200.

For example, first, when the movable mechanism 120 is in the expanded mode and the movable mechanism 130 is in the collapsed mode, the movable mechanism 120 moves in the direction of the water flow WD, and the movable mechanism 130 counters the water flow of the water flow WD Move in the direction so that the power generation module 110 obtains a driving force via the cable 140 to generate power. In other words, the movable mechanism 120 moves away from the power generation module 110 (moves along the second direction P2), and the movable mechanism 130 moves toward the direction closer to the power generation module 110 (moves against the second direction P2) . Then, after the movable mechanism 120 moves to the farthest movable distance, the movable mechanism 120 switches to the collapsed mode, and the movable mechanism 130 can be switched to the expanded mode, so that the movable mechanism 130 follows the flow direction of the water flow WD It moves, and the movable mechanism 120 moves against the water flow direction of the water flow WD. By analogy, the movable mechanisms 120 and 130 of this embodiment can utilize the characteristic that the water flow WD of the flowing water area 200 continuously flows in a single direction to alternately move back and forth alternately. Therefore, the power generation module 110 of the present embodiment can further utilize the reciprocating movement of the movable mechanisms 120 and 130 repeatedly to obtain the rotational power obtained through the cable 140 to efficiently generate power.

FIG. 2 is a top structural view of a stream power generator according to an embodiment of the invention. Referring to FIG. 2, the stream power generation device 300 includes a power generation module 310, two movable mechanisms 320 and 330 and a cable 340. In the present embodiment, the movable mechanisms 320 and 330 are connected to the power generation module 310 via the cable 340, and are linked by being pulled by the cable 340 to each other. The movable mechanism 320 is connected to one end of the cable 340, and the movable mechanism 330 is connected to the other end of the cable 340. In this embodiment, the water flow WD may, for example, be fixedly flowing toward the second direction P2 to push the movable mechanism 320 in the expanded mode away from the power generation module 310, and the movable mechanism 330 is pulled by the cable 340 and pulled Move toward the power generation module 310.

Specifically, the movable mechanism 320 includes a main board 321, two wings 322, 323, a deployment mechanism 324, and a main spring 325. The main spring 325 is sheathed on the cable 340, and one end is disposed on the main board 321, and the other end away from the main board 321 is fixed to the cable 340. The main board surface of the main board 321 is disposed perpendicular to the water flow direction of the water flow WD. The wings 322 and 323 are swingably disposed on both sides of the main board 321. The deployment mechanism 324 is provided on the main board 321 and connects the cable 340. The movable mechanism 330 includes a main board 331, two wings 332, 333, a deployment mechanism 334, and a main spring 335. The main spring 335 is sheathed on the cable 340, and one end is disposed on the main board 331, and the other end away from the main board 331 is fixed to the cable 340. The main board surface of the main board 331 is disposed perpendicular to the water flow direction of the water flow WD. The wings 332 and 333 are swingably disposed on both sides of the main board 331. The deployment mechanism 334 is provided on the main board 331 and connects the cable 340. In this embodiment, when the movable mechanism 320 is in the unfolding mode, the wings 322 and 323 are unfolded after swinging to form a large area plane with the main board 321. When the movable mechanism 330 is in the collapsed mode, the flap 332 swings counterclockwise, and the flap 333 swings clockwise and then collapses to be perpendicular to the main board 321, respectively.

In other words, when the movable mechanism 320 is in the unfolded mode, since the main board 321 and the wings 322 and 323 form a large-area flat surface, this large-area flat surface can receive more water flow WD thrust and make it movable The mechanism 320 moves in the direction of the water flow WD. At the same time, when the movable mechanism 330 is in the collapsing mode, since the wings 332 and 333 are pushed perpendicular to the main board 331 by the water flow WD, the movable mechanism 330 receives only the water flow WD received by the main board 331 with a small water flow thrust ( The water resistance is small) and is less than the pulling force provided to the cable 340 via the moving mechanism 320, so that the movable mechanism 330 moves against the water flow direction of the water flow WD.

It is worth noting that when the movable mechanism 320 moves to the farthest movable distance, if the cable 340 provides a pulling force greater than the elastic force of the main spring 325, the main spring 325 is stretched and provides a buffer distance. And, at the next alternate time point, when the main spring 325 is fully stretched, the flaps 322, 323 of the movable mechanism 320 will swing and collapse to switch to the collapsed mode. At the same time, the movable mechanism 330 moves to the power generation module 310 to abut against the stop portion (not shown) by the main spring 335, and switches to the deployment mode. Therefore, at the next alternate time point, the wings 332, 333 of the movable mechanism 330 can receive the water flow thrust to the water flow WD after being deployed to move away from the power generation module 310, and the wings 322, 323 of the movable mechanism 320 are folded, It is pulled toward the power generation module 310 by being pulled by the cable 340. By analogy, at the next alternate time point, the movable mechanisms 320, 330 will alternate round trips again. Therefore, the power generation module 310 of the present embodiment can obtain rotary power via the cable 340 based on the reciprocating and reciprocating movement of the movable mechanisms 320 and 330 to efficiently generate power.

In addition, in an embodiment, the stream power generation device 300 may further include a guide (not shown) disposed along the second direction P2, such as a guide rail or a slide rail. That is, the movable mechanisms 320, 330 can be combined with the guide so that the movable mechanisms 320, 330 move linearly along the guide without offset.

FIG. 3 is a side structural view of the stream power generator of the embodiment of FIG. 2 according to the present invention. 2 and 3, the stream power generation device 300 may further include a cable 340' and guide rails 350, 350', 360, 360'. The movable mechanism 320 may further include a main spring 325'. The movable mechanism 330 may further include a main spring 335'. The power generation module 310 may include a rotatable mechanism 311, a speed increaser (speed increaser) 312, and a generator 313. The generator 313 may include, for example, a rotor and a stator, where the rotor may receive the rotational power described in the embodiments of the present invention, so that the rotor may rotate corresponding to the stator, thereby generating electricity.

In this embodiment, the upper and lower sides of the main board 321 of the movable mechanism 320 may be installed in the guide rails 350, 350' so that the main board 321 of the movable mechanism 320 can move along the guide rails 350, 350'. The upper and lower sides of the main board 331 of the movable mechanism 330 may be installed in the guide rails 360, 360' so that the main board 331 of the movable mechanism 330 can move along the guide rails 360, 360'. Moreover, in this embodiment, the two ends of the main board 321 of the movable mechanism 320 can be connected with cables 340, 340', and the main springs 325, 325' are sleeved so that the movable mechanism 320 can follow the guide rail 350, 350' and move linearly steadily. Similarly, the two ends of the main board 331 of the movable mechanism 330 can be connected with cables 340, 340', and the main springs 335, 335' are sleeved so that the movable mechanism 330 can be stably along the guide rails 360, 360' Move straight. In other words, the cables 340, 340' are synchronously stretched and simultaneously provide rotational power to the power generation module 310.

Furthermore, in this embodiment, the rotatable mechanism 311 can have, for example, two turntables and a rotating shaft, so that the cables 340 and 340' can be individually sleeved on a turntable of the rotatable mechanism 311, and The rotation mechanism 311 can rotate correspondingly as the cables 340, 340' are stretched. In this embodiment, the speed increaser 312 is coupled to the generator 313 and is provided on the rotatable mechanism 311. Therefore, when the movable mechanisms 320, 330 are linked, the speed-increasing gear 312 supplies the rotational power obtained by the rotatable mechanism 311 via the cables 340, 340' to the generator 313 to generate electricity. Therefore, the movable mechanisms 320 and 330 of this embodiment can automatically and smoothly move back and forth repeatedly, and accordingly the generator 313 can generate electricity stably and continuously.

4 is a structural diagram of a movable mechanism according to an embodiment of the present invention. Referring to FIG. 4, the movable mechanism 420 of FIG. 4 is an embodiment of the movable mechanism applicable to the embodiments of the present invention, but the present invention is not limited thereto. In this embodiment, the movable mechanism 420 includes a main board 421, wings 422, 423, a deployment mechanism 424 and a main spring 425. The main spring 425 is sheathed on the cable 440, and one end is disposed on the main board 421, and the other end away from the main board 321 is fixed to the cable 440. In this embodiment, the deployment mechanism 424 further includes a prop 427 and a secondary spring 428. The top brace 427 passes through the main board 421 and the unfolding mechanism 424, and connects one end of the cable 440. The end of the cable 440 is fixed to the main spring 425 at the buffer section 441 of the cable 440. The linear length is greater than the free length of the main spring 425, and the difference between the linear length of the buffer section 441 and the free length of the main spring 425 is the buffer length. The prop 427 may be, for example, a bolt. The secondary spring 428 is sleeved on the top support member 427. One end of the secondary spring 428 is pressed against a radial flange (not shown) of the top support member 427, and the other end is pressed against the main board 421. In this embodiment, the deployment mechanism 424 further has two sliders 426, 426' that can reciprocally move relative to the first direction P1. The prop member 427 can penetrate into or pull out of the gap provided in the two sliders 426, 426' to move the sliders 426, 426' away from or close to each other. In this embodiment, the main board surface of the main board 421 is disposed perpendicular to the water flow direction of the water flow WD. The wings 422 and 423 can be combined with the main board 421 by a rotatable element (not shown) to be swingably disposed on both sides of the main board 421. In this embodiment, the deployment mechanism 424 determines whether to collapse or deploy the wings 422 and 423 according to the tensile force of the cable 440.

In detail, the movable mechanism 420 shown in FIG. 4 is in the expanded mode. In the deployment mode, when the pulling force provided by the cable 440 is less than an elastic force of the main spring 425, and the buffer section 411 of the cable 440 is not straightened. The pulling force provided by the cable 440 to the secondary spring 428 is less than the elastic force of the secondary spring 428 against the supporting member 427. Therefore, as shown in FIG. 4, the prop 427 is pushed to the position of clamping the deployment mechanism 424 via the secondary spring 428, and the sliders 426, 426' are away from each other, so that the wings 422, 423 are supported and deployed. However, during the movement of the movable mechanism 420, when the cable 440 provides a greater pulling force than the main spring 425, and the movable mechanism 420 has moved to the farthest movable distance, the main spring 425 may be stretched and the cable The buffer section 441 of the wire 440 is completely straightened. When the cable 440 provides a pulling force greater than the elastic force of the main spring 425, and the secondary spring 428 is compressed, the prop 427 is displaced in a direction opposite to the second direction P2, so that The prop 427 is loosened from the gap of the deployment mechanism 424. Moreover, the sliders 426, 426' are brought close to each other by a return element (such as a spring, not shown), and no longer support the wings 422, 423, so that the wings 422, 423 swing and collapse. In this regard, the movable mechanism 420 can be switched to the collapsed mode.

In other words, after the top brace 427 is pulled by the cable 440, if the top brace 427 no longer clamps the deployment mechanism 424, the wings 422, 423 will automatically collapse. By analogy, when the pulling force provided by the cable 440 is less than the elastic force of the secondary spring 428 against the prop 427, the secondary spring 428 resets the prop 427 to tighten the deployment mechanism 424 again, and the sliders 426, 426' Away from each other, the wings 422, 423 swing and expand. In this regard, the movable mechanism 420 can be switched to the expanded mode again. Therefore, the movable mechanism 420 of this embodiment can be repeatedly operated in the expanded mode and the collapsed mode to generate an automatic continuous movement effect.

In summary, the stream-type power generation device of the present invention can place two movable mechanisms in a flowing water area with a single water flow direction, and the two movable mechanisms can automatically and repeatedly switch between the deployment mode and the In the combined mode, the two movable mechanisms are pulled and displaced in the flowing water to continuously generate driving force to the power generation module, so that the power generation module can provide good and stable power generation efficiency. In addition, from another point of view, since the stream-type power generation device of the present invention does not require complicated mechanism installation (no need to install a diversion plate and a deflector), the river-type power generation device of the present invention can also effectively avoid damage The biosphere ecology of flowing waters has the characteristics of not easily affecting the drainage flow of flowing waters.
