The present invention relates to a canal flow energy conversion device, in particular to a canal flow energy conversion device that can be used for hydroelectric power generation.

One of the existing canal flow energy conversion devices is to use the top-down momentum of the water flow to impact the turbine, so as to convert the potential energy difference of the water flow into kinetic energy to drive the generator to operate and generate electricity. In order to allow the water flow to have a sufficient potential energy difference, the existing canal flow energy conversion device must be built at a place with an obvious height difference in the river to provide sufficient impulse for the operation of the turbine. However, rivers in the natural environment have variable landforms, and it is often not suitable to build canal flow energy conversion devices without river regulation. In addition, due to the influence of seasons and weather, rivers often have insufficient flow due to lack of rain, causing generators to be unable to generate electricity.

In some embodiments, the shortest distance in the width direction of the water channel from one edge of the water guide vortex to one edge of the water collecting port is one quarter of the inner diameter of the water collecting port.

In some implementations, the canal flow energy conversion device further includes a guide impeller. The guide impeller is located in the water guide vortex and aligned with the water collection port, and is pivotally connected to the transmission component. The guide impeller has a plurality of guide blades. The length of each guide vane is greater than half of the inner diameter of the water collection port. The water guide vortex can allow the water in the water channel to be introduced from the water inlet to the water collection port to drive the guide wheel paddle to rotate.

In some implementations, the canal flow energy conversion device further includes a guide impeller. The guide impeller is located in the water guide vortex and aligned with the water collection port, and is pivotally connected to the transmission assembly. The guide impeller has a plurality of guide blades. Each guide vane has a connecting portion pivotally connected to the transmission component, and a water-repellent portion connected to an end of the connecting portion away from the transmission component. The water-repelling part is arc-shaped and has a facing surface. The angle between the extending direction of the facing surface and the extending direction of the connecting portion is 30 degrees. The water guide vortex can allow the water in the water channel to be introduced from the water inlet to the water collection port to drive the guide wheel paddle to rotate.

In some implementations, the kinetic energy conversion structure includes a plurality of turbine blades. The turbine blades are spaced apart in the extending direction of the pipeline.

In some implementations, the channel flow energy conversion device further includes a gate unit.

As shown in Figure 2, when the door panel 12 is operated and moves to the bottom of the door frame 11, the door panel 12 blocks the bottom of the gate channel 111 and restricts the water 81 of the water channel 8 from flowing through the bottom of the gate channel 111. At this time, the water 81 of the water channel 8 will collect on the side of the gate unit 1 adjacent to the upstream side of the water channel 8 , so that the water level in the water channel 8 gradually increases. When the water level in the water channel 8 is higher than the top edge of the door panel 12 , the water 81 in the water channel 8 will pass through the top of the gate channel 111 and fall downward from a high place, forming a water flow with a height difference.

The pipe 411 can allow the water 81 of the water channel 8 to pass from top to bottom (as shown by the small and medium arrows) to drive the turbine blades 42 to rotate. The turbine blades 42 can be driven by the water flow to rotate, and drive the transmission assembly 43 to operate. The turbine blades 42 are, for example, but not limited to propellers, and are arranged at intervals in the extension direction of the pipe 411 . In this embodiment, the number of the turbine blades 42 is two, but the number of the turbine blades 42 may also be three or more or only one, depending on the depth of the waterway 8 .

The transmission assembly 43 has a transmission shaft 431 , a transmission gear plate 432 and a transmission member 433 . The transmission shaft 431 is vertically pivoted on the axis center of the turbine blades 42 . The transmission gear plate 432 is pivotally connected to the transmission shaft 431 , and the heights of the transmission gear plate 432 , the generator gear plate 24 and the water pump gear plate 32 are equal. The transmission member 433 is, for example, a chain or a flexible transmission chain belt, but is not limited thereto. The transmission member 433 is sleeved on the transmission gear plate 432 , the generator gear plate 24 and the water pump gear plate 32 . When the transmission shaft 431 is driven by the turbine blades 42 to pivot, the transmission shaft 431 will drive the transmission gear plate 432 to rotate, thereby causing the generator gear plate 24 and the water pump gear plate 32 to rotate synchronously, and The generator 2 is allowed to generate electric energy and the water pump 3 is allowed to carry out water pumping operation.

Referring to Figures 2 and 3, the water guide plate 5 is in the shape of a rectangular plate, but is not limited thereto, and extends along the water flow direction X. The width of the water guide plate 5 is equivalent to the width of the gate unit 1 . And the water guide plate 5 is located on the downstream side of the gate unit 1 adjacent to the water channel 8 . The water guide plate 5 is disposed above the standpipe 41 and includes a water guide vortex 51 . The water guide vortex 51 is in a vortex shape and has a curved portion 511 and a water collecting portion 512 farther away from the gate unit 1 than the curved portion 511 . The water guide vortex 51 can allow the water 81 in the water channel 8 to flow from the curved portion 511 to the water collection portion 512 . The curved portion 511 has a water inlet 513 facing upstream of the water channel 8 . The water inlet 513 is connected to the top of the gate channel 111 and can guide the water 81 from the top of the gate channel 111 into the curved portion 511 . The water collection part 512 has a water collection port 514 that opens downward and communicates with the pipe 411 . The water collection port 514 is adjacent to the downstream of the water channel 8 than the water inlet 513 and can guide the water 81 from the bend 511 to the pipe 411 .

The water guide vortex 51 is centered around the water collecting port 514 and extends outward to the water inlet 513 . And the diameter of the water inlet 513 in the width direction Y of the water channel 8 tapers along the water flow direction X. Specifically, the curved portion 511 extends from the water inlet 513 to the water collecting portion 512 along a gentle curve (not shown) similar to a Clothoid curve. The shortest distance L1 from the side edge of the water guide vortex 51 away from the water inlet 513 to the side edge of the water collection port 514 is half of the inner diameter d1 of the water collection port 514 . The shortest distance L2 in the width direction Y of the water channel 8 from one side edge of the water guide vortex 51 to one side edge of the water collection port 514 is one-quarter of the inner diameter d1 of the water collection port 514 . In this way, the cross-section perpendicular to the flow direction of the water 81 in the water-guiding vortex groove 51 will decrease gently, and the water 81 in the water-guiding vortex groove 51 will flow smoothly and quickly along the groove wall in the water-guiding vortex groove 51 It flows into the pipe 411 to impact the turbine blades 42 to cause them to rotate rapidly.

The guide impeller 6 is located in the water guide vortex 51 and aligned with the water collection port 514 , and is pivotally connected to the transmission assembly 43 . The guide blade 6 has a plurality of guide blades 61 . The guide vanes 61 respectively extend in different directions on the horizontal plane from the transmission shaft 431 . The length d2 of each guide vane 61 is greater than half of the inner diameter d1 of the water collection port 514 . Specifically, the length d2 of each guide vane 61 is 5 cm longer than half of the inner diameter d1 of the water collection port 514 . In this way, when any two of the guide vanes 61 are respectively disposed on two opposite sides of the transmission shaft 431, the overall outer diameter of the guide blade 6 will be larger than the inner diameter d1 of the water collection port 514, and can The water 81 from the periphery of the water collection port 514 is brought into the water collection port 514 to effectively concentrate the water flow. In addition, each guide vane 61 has a connecting portion 611 pivotally connected to the transmission component 43, and an end of the connecting portion 611 away from the transmission component 43 curvedly extends in a direction close to the adjacent guide vane 61. The water repellent part 612. The water-repelling portion 612 is arc-shaped and has a facing surface 613 for horizontally repelling the water 81 . The included angle θ between the extension direction of the facing surface 613 and the extension direction of the connecting portion 611 is 30 degrees, so that when the deflector paddle 6 moves the water 81 horizontally, it can also convert part of the fluid kinetic energy. This generates kinetic energy to drive the transmission shaft 431 to pivot, thereby improving the power generation efficiency of the generator 2 .

Referring to Figures 1 and 2, when the water depth of the water channel 8 is sufficient, as long as the channel flow energy conversion device is installed in the water channel 8, and the direction of the water collection port 514 is toward the upstream of the water channel 8, the water channel 8 can be Water 81 in the water channel 8 is introduced into the water collection port 514 from the water inlet 513 to drive the guide wheel paddle 6 to rotate. However, when the water depth of the water channel 8 is lower than the water guide plate 5 as shown in Figure 1, the door panel 12 of the gate unit 1 can be moved downward as shown in Figure 2 to cover the bottom of the gate channel 111, so that the water channel 8 The water level in the water guide plate 5 rises to a level higher than the bottom of the water guide plate 5 . At this time, as shown by the middle arrow, the water 81 in the water channel 8 will naturally flow into the water guide vortex 51 along the water flow direction X, and the water guide vortex 51 will allow the water 81 in the water channel 8 to flow from the water inlet. 513 flows into the pipe 411 to impact the turbine blades 42 to cause them to rotate rapidly. When the turbine blades 42 are impacted and rotate rapidly, the impact force of the water flow is converted into the torsion of the transmission shaft 431, thereby driving the transmission gear plate 432 to rotate, and the transmission member 433 is used to drive the water pump 3 The water pump gear plate 32 or the generator gear plate 24 of the generator 2 . By converting the high torque of the transmission gear plate 432 into the high rotation speed of the water pump gear plate 32 or the generator gear plate 24, the water pump 3 or the generator 2 is driven to operate.

Specifically, the channel flow energy conversion device is a multifunctional device that can convert the kinetic energy of the water flow in the water channel 8 into mechanical energy. The canal flow energy conversion device can not only be used as a hydroelectric power generation system, but also allow the turbine blades 42 to drive the transmission shaft 431 to drive the water pump 3 through the transmission member 433 (flexible transmission chain belt). The water pump 3 can pump water from a low place to a high place, thereby realizing the function of a water pump.

The working principle of the canal flow energy conversion device is: the water in the water channel 8 passes through the standpipe 41 and drives the turbine blades 42 to rotate, thereby driving the transmission assembly 43 to operate. The transmission assembly 43 drives the water pump 3 through the transmission member 433 (flexible transmission chain belt). When the transmission shaft 431 rotates, the water pump 3 starts to operate, pumping water from a low place to a high place. The water guide plate 5 is located above the standpipe 41 and includes the water guide vortex 51 , and the water guide vortex 51 has the water inlet 513 to allow water in the water channel 8 to flow into the standpipe 41 . The water inlet 513 is tapered along the direction of water flow, so that the water flow in the water channel 8 can be concentrated and the water flow rate is increased, thereby increasing the efficiency of the channel flow energy conversion device for hydropower generation.

The multi-functional feature of the canal flow energy conversion device allows the canal flow energy conversion device to be used in the water channel 8 with a small flow rate to convert the water flow energy in the water channel 8 into mechanical energy to realize the functions of hydropower generation and water pumping. The use of the canal flow energy conversion device can improve the utilization efficiency of water resources and reduce the impact on the environment, and has broad application prospects.

To sum up, through the design of the tapered diameter of the water inlet 513, the water flow flowing into the water inlet 513 can be concentrated, thereby increasing the water flow rate and flow speed that drives the turbine blades 42 to rotate, and converting the flow energy of the canal. The device can be installed in the water channel 8 where the water flow is small or the slope is gentle. In addition, because the water-guiding vortex groove 51 is in a winding and expanded shape or extends along the gentle curve, the water flow in the water-guiding vortex groove 51 can flow along the groove wall of the water-guiding vortex groove 51, thereby preventing the water-guiding vortex groove 51 from flowing along the wall of the water-guiding vortex groove 51. The water flow in the vortex groove 51 generates turbulent flow due to the impact on the groove wall of the water-guiding vortex groove 51, so that the water 81 in the water-guiding vortex groove 51 maintains a constant flow speed while being collected, and is better suitable for the water-guiding vortex groove 51. The channel flow energy conversion device is installed in the water channel 8 where the water flow is small or the slope is gentle. On the other hand, by disposing the guide impeller 6 above the water collection port 514, the water flow in the water guide vortex 51 can enter the pipe 411 along a spiral path to avoid turbulence. The impeller 6 is driven and rotated by the water flow in the water guide vortex 51 and will also drive the transmission assembly 43 to operate, thereby improving the power generation efficiency of the generator 2, so the purpose of the present invention can indeed be achieved.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the contents of the patent specification are still included in the scope of the present invention.
