Description

Technical Field

[0001] This invention belongs to the field of hydropower equipment, specifically to a photovoltaic and hydropower integrated power generation device and power generation method. Background Technology

[0002] In the field of river-based renewable energy generation, traditional technical solutions are mostly concentrated on turbine units in large hydropower stations or small run-of-river turbine generators. These devices are usually complex in structure, expensive, and have high requirements for river flow velocity, water depth, and topography, making them difficult to deploy effectively in vast plains or irrigation canals with low flow velocity and shallow water levels. In addition, low-water-head power generation devices, such as waterwheels, generally have low energy conversion efficiency and rely on the continuous propulsion of water flow. During dry seasons or when flow fluctuates, the impact force carried by the unidirectional flow of water is small, resulting in a small impact force on the energy conversion components in the power generation device, leading to poor power generation stability. On the other hand, in order to compensate for the intermittent nature of a single energy source, existing technologies have developed systems that combine photovoltaic power generation with turbine units. However, the integration method is usually loose, with photovoltaic panels often independently mounted on the bank or floating platforms on the water surface, failing to form a compact integrated structure with the hydropower generation unit. This separate design not only increases the footprint and overall cost but also fails to make full use of the space above the river. Summary of the Invention

[0003] To address the issues that power generation devices cannot continuously generate electricity in vast plains, rivers, or irrigation canals with low flow rates and shallow water levels, and that photovoltaic panels and hydropower devices require large installation spaces when installed independently, this invention provides an integrated photovoltaic and hydropower power generation device and method.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention proposes a photovoltaic and hydropower integrated power generation device, including a connecting base plate fixed in a river channel, a hydropower generation component disposed on the connecting base plate, and a photovoltaic panel installed on the top of the hydropower generation component;

[0006] The hydroelectric power generation component includes a circular sliding rail fixed to the connecting base plate. A generator is installed on one end of the circular sliding rail away from the connecting base plate. The photovoltaic panel is installed on the circular sliding rail and located above the generator.

The multiple guide members are evenly distributed on the circular sliding rail.

[0007] A transmission rack is provided on the circular sliding rail between two adjacent guide members. The end of the transmission rack is connected to the power generation traction rope. The transmission rack is connected to an impeller through a transmission assembly.

[0013] A U-shaped connecting plate is provided on the outer wall of the first sliding sleeve. The transmission component is installed on one end face of the U-shaped connecting plate opposite to the first sliding sleeve.

[0014] Preferably, the transmission assembly includes a transmission shaft rotatably mounted on the U-shaped connecting plate, and the impeller is fixedly mounted on the end of the transmission shaft away from the circular sliding rail;

[0015] A drive gear and a mating gear are installed on the end of the U-shaped connecting plate near the circular sliding rail. A mating gear is provided between the drive gear and the mating gear. The mating gear is fixed on the U-shaped connecting plate by an L-shaped fixing plate. The mating gear meshes with the drive gear or the mating gear.

[0016] Wherein, the length of the multiple teeth in the driving gear arranged at equal intervals is half the circumferential length of the driving gear, and the length of the multiple teeth in the mating gear disk arranged at equal intervals is half the circumferential length of the mating gear disk.

[0017] A turbine is coaxially connected to the mating gear, and a worm gear that meshes with the turbine is connected to the U-shaped connecting plate. The worm gear meshes with the transmission rack.

[0018] The U-shaped connecting plate is provided with a sliding stage, on which the transmission rack is slidably mounted.

[0019] Preferably, an outer connecting shaft is provided on the end of the drive shaft away from the circular sliding rail, and a sprocket is provided on the outer connecting shaft. A cooperating chain is connected between the multiple sprockets on one of the circular sliding rails.

[0023] The other two ends of the cross-shaped connecting plate are provided with second fixed clamps, and two second limit wheels are rotatably mounted on the second fixed clamps. The power generation traction rope is threaded between the two second limit wheels.

[0024] Preferably, the first connecting base plate is provided with a second flange plate parallel to the first flange plate, a web plate is provided between the second flange plate and the first flange plate, and a first diagonal brace is provided between the second flange plate and the first connecting base plate. One end of the first diagonal brace is fixed to the end face of the second flange plate away from the first flange plate, and the other end of the first diagonal brace is fixed to the first connecting base plate at a position away from the second flange plate.

[0025] A flow straightener is provided on the second flange.

[0026] This invention proposes a method for integrated photovoltaic and hydropower generation based on the aforementioned integrated photovoltaic and hydropower generation device, comprising the following steps:

[0027] The connecting base plate is fixed in the river channel. The water flow in the river channel impacts the impeller in the hydroelectric power generation component, driving the impeller to rotate. The impeller drives the transmission rack to reciprocate on the circular sliding rail in a direction perpendicular to the axis of the circular sliding rail through the transmission component.

[0028] During the reciprocating movement of the transmission rack, with the cooperation of the guide member, the rack pulls the generator traction rope, which in turn pulls the generator's pull rope, thus enabling the generator to move.

[0029] Meanwhile, the photovoltaic panel captures solar energy to generate photovoltaic power.

[0030] Compared with the prior art, the present invention has the following beneficial technical effects:

[0031] This invention proposes an integrated photovoltaic and hydropower generation device. In this device, photovoltaic panels and hydropower generation are integrated on a circular sliding rail, realizing the integration of photovoltaic and hydropower generation. There is no need to plan separate installation areas for photovoltaic panels and hydropower devices. It is especially suitable for narrow spaces such as rivers and irrigation canals, which greatly saves land or water area. At the same time, in the hydropower generation component of this device, the impeller is in direct contact with the river water flow. Even at low flow velocities, the impact force of the water flow can still drive the impeller to rotate. The rotation is transmitted to the power generation traction rope through the transmission rack, which then drives the generator to work, without relying on high water level differences or high flow velocities.

[0032] Furthermore, this device incorporates multiple sets of hydroelectric power generation components along the width of the river channel, increasing the contact area between the device and the water flow, as well as the number of power generation units, thereby improving power generation efficiency. Simultaneously, the multiple hydroelectric power generation components arranged in the same row are connected in series via flexible connectors. When the water flow velocity is high, i.e., when the impact force is large, the flexible connectors can mitigate the impact force, preventing multiple sets of components from pulling and damaging each other due to rigid connections, thus extending the service life of the equipment.

[0033] Furthermore, this device achieves layered positioning of the guide and sliding components through the first and second flexible connectors, enabling the guide and sliding components to operate independently and stably, avoiding mutual interference between the sliding components and guides, which would affect the power generation efficiency of the device. Simultaneously, in this device, guides located at the same height among multiple hydroelectric power generation components are connected in series by a first steel rope in the first flexible connector, and sliding components at the same height are connected in series by a second steel rope. This simplifies the fixing structure and, through the first and second flexible connectors, buffers some of the water flow impact force received by the device, avoiding stress concentration caused by rigid connections, thus improving the durability of the device. It also facilitates rapid disassembly of the device, improving assembly and disassembly efficiency and shortening assembly and disassembly time.

[0034] Furthermore, in this device, the sliding assembly uses a first sliding sleeve to fix the transmission assembly on a circular sliding rail, while a second sliding sleeve, in conjunction with a second steel rope, flexibly fixes the transmission assembly. This makes the device more resistant to long-term water erosion and corrosion, increasing its service life in river channels. It also facilitates quick disassembly, improving assembly and disassembly efficiency and shortening assembly and disassembly time. At the same time, the U-shaped connecting plate provides a sufficiently large installation space for the transmission assembly, reducing malfunctions caused by mechanical interference.

[0035] Furthermore, in this device, the transmission assembly connects the impeller, drive gear, and mating gear disc via a drive shaft. A planetary gear transmission structure is formed between the drive gear and the mating gear disc, which, in conjunction with a turbine and worm gear, stably drives the transmission rack. The transmission rack then drives the generator traction rope, enabling the generator to generate electricity stably. In the transmission assembly, the length of multiple equally spaced teeth on the drive gear is half the circumferential length of the drive gear, and the length of multiple equally spaced teeth on the mating gear disc is half the circumferential length of the mating gear disc. This allows the mating gear to alternately mesh with the drive gear and the mating gear disc. When meshing with the drive gear, it drives the transmission rack to move in one direction; when meshing with the mating gear disc, it drives it to move in the opposite direction. This reciprocating motion allows the impeller to output power twice per revolution, improving the generator's efficiency. Even if the water flow drives the impeller at a relatively slow speed, the reciprocating motion still accumulates tension through bidirectional superposition, ensuring the generator traction rope continuously receives driving force and improving the energy conversion efficiency per unit time.

[0036] Furthermore, the guide component of this device is connected to the circular sliding rail via the second sliding sleeve. The second sliding sleeve is connected to the first fixed ring via the cross-shaped connecting plate. The cross-shaped connecting plate flexibly fixes the generator traction rope through the cooperation of two second limiting plates and the second limiting wheel, thereby flexibly limiting the generator traction rope connected to the generator's pull rope. This allows the transmission rack to stably pull the generator traction rope during movement, increasing the stability of hydropower generation.

[0037] Furthermore, this device has a second flange plate connected to the first flange plate via a web plate. The second flange plate blocks debris in the river flow, preventing it from flowing directly towards the impeller and causing damage. At the same time, the web plate and the second flange plate increase the stability of the first flange plate when mounted on the first connecting base plate. A first diagonal brace is provided between the second flange plate and the first connecting base plate, which increases the connection stability between the second flange plate and the first connecting base plate. This allows the device to withstand the impact of large water flows in the river and extends its service life.

[0038] Furthermore, the device is equipped with a flow straightening port on the second flange plate. The flow straightening port helps to regulate the water flow from the river to the impeller, preventing the water flow from forming eddies at the impeller and causing damage to the impeller.

[0057] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0059] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0060] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0062] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0063] This invention proposes an integrated photovoltaic and hydropower generation device, such as... Figures 1-17 As shown, it includes a connecting base plate fixed in the river channel. The connecting base plate includes a first connecting base plate 1. A concrete base plate is provided on the lower end face of the first connecting base plate 1. The first connecting base plate 1 is stably fixed in the river channel by the concrete base plate. The first connecting base plate 1 is arranged along the direction of water flow in the river channel. A hydropower generation component is provided on the first connecting base plate 1. A photovoltaic panel 36 is installed on the top of the hydropower generation component. After the photovoltaic panel 36 is installed, the bottom position of the photovoltaic panel 36 is higher than the water surface of the river channel.

[0064] The hydroelectric power generation component includes a first connecting base plate 1, a second connecting base plate 20 is provided at one end of the first connecting base plate 1, a circular sliding rail 11 is fixed on the upper end face of the second connecting base plate 20, the circular sliding rail 11 is vertically installed on the upper end face of the first connecting base plate 1, a Y-shaped connecting plate 6 is installed at the end of the circular sliding rail 11 away from the first connecting base plate 1, a connecting ring 35 is provided at the Y-shaped opening of the Y-shaped connecting plate 6, and a generator 34 is installed inside the connecting ring 35, that is, two generators 34 are installed at the top end of one circular sliding rail 11. The pull ropes of the two generators 34 are set vertically downwards. The photovoltaic panel 36 is installed on the circular sliding rail 11 and is located above the generator 34. The height at which the generator 34 is installed on the circular sliding rail 11 is higher than the height that the water surface on the circular sliding rail 11 can reach. The pull rope of the generator 34 is connected to the generator traction rope 7. The generator traction rope 7 is connected to multiple guide members. The multiple guide members are evenly distributed on the circular sliding rail 11, and the guide members near the first connecting base plate 1 are fixedly connected to the end of the generator traction rope 7 away from the generator 34.

[0065] A transmission rack 16 is provided on the circular sliding rail 11 between two adjacent guide members. The end of the transmission rack 16 is connected to the generator traction rope 7. The transmission rack 16 is connected to the impeller 14 through the transmission assembly. The impeller 14 rotates under the action of the water flow in the river, driving the transmission assembly to work and pulling the generator traction rope 7 to make the generator 34 generate electricity. This device integrates photovoltaic and hydropower generation on a circular sliding rail 11, reducing the area occupied by the equipment installation. Furthermore, a transmission assembly is installed on the circular sliding rail 11 between two adjacent guide members. An impeller 14 is connected to this transmission assembly, directly harnessing the power of the river flow. Even at low flow velocities, the impact force of the water flow can still drive the impeller 14 to rotate. The impeller 14 rotates under the impact of the river flow, and the torque generated by its rotation is transmitted to the generator traction rope 7 via a transmission rack 16. The generator traction rope 7 then pulls the generator 34 to operate. This eliminates the need for high water level differences or high flow velocities. Moreover, the direct connection between the transmission rack 16, impeller 14, and generator traction rope 7 results in a short transmission path and stable mechanical contact, reducing energy loss in intermediate stages, lowering the probability of component failure, and extending the device's service life.

[0066] like Figure 1 and Figure 2As shown, multiple hydroelectric power generation components are arranged to maximize the use of water flow energy at the same cross-section of the river. Multiple hydroelectric power generation components are arranged in rows along the width of the river. In this embodiment, the row of hydroelectric power generation components is arranged in two or more positions along the direction of water flow in the river. Photovoltaic panels 36 are installed on the top of the multiple rows of hydroelectric power generation components. Multiple hydroelectric power generation components in the same row along the width of the river are connected in series by flexible connectors. This allows the device to flexibly cope with the non-standard shape of the river and the instability of the water flow. When the water flow velocity is high, i.e., the impact force is large, the flexible connectors can buffer the impact force and prevent multiple groups of components from being pulled and damaged by each other due to rigid connection, thus extending the service life of the equipment. The two ends of the flexible connectors are respectively fixed with side fixing plates 4. The side fixing plates 4 are vertically fixed to the side of the river and are parallel to the circular sliding rail 11. The two side fixing plates 4 further increase the stability of the device installed in the river.

[0067] Preferably, a transition connecting plate 37 is provided on the upper end face of the Y-shaped connecting plate 6 among the multiple hydropower generation components. A photovoltaic mounting frame is connected to the top end of the transition connecting plate 37, and a photovoltaic panel 36 is installed in the photovoltaic mounting frame. In this embodiment, the generator 34 is a pull-out generator.

[0068] like Figure 1 , Figure 2 , Figure 12 , Figure 14 and Figure 15 As shown, the flexible connector includes a first flexible connector and a second flexible connector.

[0069] The first flexible component includes a first steel rope 5, the end of which is connected to a side fixing plate 4, i.e., the first steel rope 5 is connected between two side fixing plates 4 to taut the first steel rope 5. Multiple first fixing rings 31 are provided on the first steel rope 5. The first fixing rings 31 are fixed on the outside of the guide component, and the guide component corresponds to the first fixing ring 31 one by one. The guide components located at the same height in multiple hydroelectric power generation components are connected in series by a first steel rope 5 to flexibly limit the guide component.

[0070] The second flexible connector includes a second steel rope 40, the end of which is connected to a side fixing plate 4, i.e., the second steel rope 40 is connected between two side fixing plates 4. The second steel rope 40 is taut and connected to multiple second fixing rings 15. Each second fixing ring 15 is connected to a sliding component, and the sliding components correspond one-to-one with the second fixing rings 15. The sliding components are installed on a circular sliding rail 11, and a transmission rack 16 and a transmission component are installed on the sliding components. Among the multiple hydroelectric power generation components, the sliding components located at the same height are connected in series by a second steel rope 40 to flexibly limit the sliding components on the circular sliding rail 11, restricting the movement range of the sliding components to the horizontal plane of the corresponding height, and allowing them to float in a small range with the impact of water flow, thereby increasing the hydroelectric power generation components' ability to resist water flow impact.

[0071] like Figures 1-14 As shown, the sliding assembly includes a first sliding sleeve 12 slidably mounted on a circular sliding rail 11, and two first sliding sleeves 12 are provided on the circular sliding rail 11 between two adjacent guide members. A first limiting plate 121 is provided on the first sliding sleeve 12, and a first flange plate 9 is provided on the circular sliding rail 11 along its axial direction. The first limiting plate 121 is parallel to the first flange plate 9, and the opposite end faces of the first limiting plate 121 and the first flange plate 9 are in contact with each other. The contact between the first limiting plate 121 and the first flange plate 9 prevents the first sliding sleeve 12 from rotating on the circular sliding rail 11.

[0072] Preferably, intercepting nets should be installed at intervals in the direction of the water flow to intercept larger sand, gravel, and garbage, so as to prevent sandpaper, garbage, etc. from frequently colliding with the device and affecting its operation.

[0073] A U-shaped connecting plate 13 is provided on the outer wall of the first sliding sleeve 12, and a U-shaped connecting plate 13 is connected between two first sliding sleeves 12 located between two adjacent guide members. The U-shaped connecting plate 13 is connected to the first sliding sleeve 12 at its U-shaped opening. The U-shaped connecting plate 13 makes the two first sliding sleeves 12 spaced at a certain distance, leaving enough space for the installation and operation of the transmission component and the transmission rack 16, reducing maintenance costs and extending service life. The two first sliding sleeves 12 form a double-point support structure through the U-shaped connecting plate 13, ensuring the stability of the sliding component on the circular sliding rail 11. The transmission component is installed on one end face of the U-shaped connecting plate 13 opposite to the first sliding sleeve 12, and a second fixing ring 15 is fixedly connected to the end face of the U-shaped connecting plate 13 away from the first sliding sleeve 12.

[0074] like Figures 1-14As shown, the transmission assembly includes a transmission shaft rotatably mounted on the U-shaped connecting plate 13. The axial direction of the transmission shaft is perpendicular to the axial direction of the circular sliding rail 11. An impeller 14 is fixedly mounted on the end of the transmission shaft away from the circular sliding rail 11. The impeller 14 drives the transmission shaft to rotate under the action of the flowing water.

[0075] A drive gear 21 and a mating gear disk 19 are mounted on the end of the drive shaft near the circular sliding rail 11. The mating gear disk 19 includes a connecting disc, with an internal gear ring mounted on one end face of the connecting disc. The connecting disc has mounting holes through which the drive shaft passes. The connecting disc and the drive shaft are fixed by limit screws, ensuring synchronous rotation of the connecting disc during drive shaft rotation. The mating gear disk 19 is sleeved on the outside of the drive gear 21, meaning the drive gear 21 and the internal gear ring are located on the same side of the connecting disc. The drive shaft simultaneously drives the drive gear 21 and the mating gear disk 19 to rotate synchronously. A mating gear 22 is positioned between the drive gear 21 and the mating gear disk 19, and a mounting shaft is connected to the mating gear 22. The mounting shaft rotates to install... The L-shaped fixing plate 24 supports the mounting shaft and is fixed on the end face of the U-shaped connecting plate 13 opposite to the mating gear disk 19, and is located above or below the mating gear disk 19. The mating gear 22 meshes with the driving gear 21 or the mating gear disk 19. The length of the multiple teeth of the driving gear 21 arranged at equal intervals is half of the circumferential length of the driving gear 21, and the length of the multiple teeth of the mating gear disk 19 arranged at equal intervals is half of the circumferential length of the internal gear ring. When the mating gear 22 meshes with the driving gear 21, the mating gear 22 disengages from the mating gear disk 19. When the mating gear 22 meshes with the mating gear disk 19, the mating gear 22 disengages from the driving gear 21.

[0076] A turbine 25 is connected to the end of the mounting shaft furthest from the mating gear 22. The turbine 25 rotates synchronously with the mating gear 22, and their rotation directions are the same. A connecting rod 23 is connected to the U-shaped connecting plate 13, with connecting rods 23 on both sides of the turbine 25. A worm gear 26, meshing with the turbine 25, is rotatably mounted between the two connecting rods 23. The worm gear 26 meshes with the transmission rack 16. That is, when the impeller 14 drives the drive gear 21 and the mating gear disc 19 to rotate via the transmission shaft, if the mating gear 22 meshes with the drive gear 21, the impeller 14 drives the mating gear 22 to rotate via the drive gear 21. The mating gear 22 rotates synchronously with the turbine 25, and the turbine 25 drives the worm gear 26 to rotate. When the impeller 14 moves, the worm gear 26 drives the transmission rack 16 to move in one direction. When the mating gear 22 meshes with the mating gear disk 19, the impeller 14 drives the mating gear disk 19 to rotate through the drive gear 21. The mating gear 22 and the turbine 25 rotate synchronously. The turbine 25 drives the worm gear 26 to rotate. The worm gear 26 drives the transmission rack 16 to move in another direction. This direction of movement is opposite to the direction of movement of the transmission rack 16 driven by the meshing of the mating gear 22 and the drive gear 21. That is, when the water flow in the river pushes the impeller to rotate once, the transmission rack 16 moves back and forth once. In turn, the transmission rack 16 pulls the power generation traction rope 7 connected to its end. That is, when the impeller 14 rotates once, the transmission rack 16 moves back and forth once.

[0077] A sliding platform 27 is provided on the U-shaped connecting plate 13. A second inclined support plate 30 is provided between the bottom end face of the sliding platform 27 and the U-shaped connecting plate 13. The second inclined support plate 30 enables the sliding platform 27 to be stably fixed on the U-shaped connecting plate 13. A sliding groove is provided on the sliding platform 27, and a transmission rack 16 is slidably installed in the sliding groove. The sliding platform 27 provides a stable support platform for the transmission rack 16 and limits the sliding path of the transmission rack 16, thereby providing stability for the operation of the transmission rack 16.

[0078] like Figures 1-5 , Figure 7 As shown, an outer connecting shaft 38 is provided on the end of the drive shaft away from the circular sliding rail 11. A sprocket is provided on the outer connecting shaft 38. A coordinating chain 39 is connected between multiple sprockets located on a circular sliding rail 11. Through the cooperation of the coordinating chain 39 and the sprocket, multiple impellers 14 installed on the same circular sliding rail 11 can rotate synchronously. In turn, the impellers 14 drive the transmission components to move synchronously, thereby improving the efficiency of hydropower generation.

[0079] like Figures 1-14 As shown, two first fixed clamping plates 28 are symmetrically arranged on the end of the transmission rack 16, and two first limiting wheels 29 are arranged in parallel between the two first fixed clamping plates 28. The power generation traction rope 7 is threaded between the two first limiting wheels 29, and the power generation traction rope 7 is limited and fixed by the two first limiting wheels 29.

[0080] like Figure 1 , Figure 4 , Figure 5 , Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 14 , Figure 15 and Figure 16 As shown, the guide includes a second sliding sleeve 17 slidably mounted on a circular sliding rail 11. The second sliding sleeve 17 can slide along the circular sliding rail 11. A second limiting plate 171 is provided on the outer wall of the second sliding sleeve 17. The second limiting plate 171 is parallel to the first flange plate 9, and the end faces of the second limiting plate 171 and the first flange plate 9 are in contact with each other. The second limiting plate 171 limits the second sliding sleeve 17 to prevent the second sliding sleeve 17 from rotating on the circular sliding rail 11, which would affect the hydropower generation efficiency.

[0081] A cross-shaped connecting plate 18 is connected to the outer wall of the second sliding sleeve 17 at a position away from the circular sliding rail 11. A first fixing ring 31 is fixedly connected to one end of the cross-shaped connecting plate 18 away from the circular sliding rail 11. The first fixing ring 31 cooperates with the first steel rope 5 to limit the axial displacement of the second sliding sleeve 17 along the circular sliding rail 11, so as to prevent the second sliding sleeve 17 from moving a long distance on the circular sliding rail 11. The first fixing ring 31, the first steel rope 5, the cross-shaped connecting plate 18 and the second sliding sleeve 17 form a flexible limiting structure, which increases the ability of the device to withstand water flow impact.

[0082] Two second fixing plates 32 are provided on the other two ends of the cross-shaped connecting plate 18 located on both sides of the first fixing ring 31. The two second fixing plates 32 are arranged in parallel. Two second limiting wheels 33 are rotatably arranged on the second fixing plates 32. The power generation traction rope 7 is passed through the two second limiting wheels 33, and the power generation traction rope 7 is partially fixed so that the power generation traction rope 7 can be stretched. Even if the transmission rack 16 moves within a small range, the power generation traction rope 7 can still undergo a large amount of deformation.

[0083] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, a second flange plate 3 parallel to the first flange plate 9 is provided on the first connecting base plate 1. The top end face of the second flange plate 3 is flush with the top end face of the first flange plate 9. A web plate 10 is provided between the second flange plate 3 and the first flange plate 9, connecting the second flange plate 3 and the first flange plate 9 through the web plate 10, so that the second flange plate 3 and the first flange plate 9 are stably connected together, increasing the strength of the device. A first diagonal brace plate 2 is provided between the second flange plate 3 and the first connecting base plate 1. One end of the first diagonal brace plate 2 is fixed on the end face of the second flange plate 3 away from the first flange plate 9, near its top end face. The other end of the first diagonal brace plate 2 is fixed on the upper end face of the first connecting base plate 1, away from the second flange plate 3. The first diagonal brace plate 2 increases the connection strength between the second flange plate 3 and the first connecting base plate 1, thereby increasing the overall stability of the device, so that the device can withstand the impact of large water flow in the river and extend the service life of the device.

[0084] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, rectifier ports 8 are symmetrically arranged on both sides of the second flange plate 3. The rectifier ports 8 are used to straighten the water flow to the impeller 14, so as to prevent the water flow from forming eddies at the impeller 14 and causing damage to the impeller 14. At the same time, the rectifier ports 8 can also guide the mud, sand and small stones in the water flow to avoid them accumulating in front of the second flange plate 3, affecting the water flow rate through the impeller 14, and ensuring that the impeller 14 continuously obtains a stable water flow.

[0085] This invention proposes a photovoltaic and hydropower integrated power generation method, implemented based on the aforementioned photovoltaic and hydropower integrated power generation device, comprising the following steps:

[0086] The first connecting base plate 1 and the second connecting base plate 20 are fixed in the river channel. The water flow in the river channel impacts the impeller 14 in the hydroelectric power generation component, pushing the impeller 14 to rotate. The impeller 14 drives the transmission rack 16 to move repeatedly on the circular sliding rail 11 in a direction perpendicular to the axial direction of the circular sliding rail 11 through the transmission component.

[0087] During repeated movements, the transmission rack 16, with the cooperation of the guide, pulls the generator traction rope 7, which in turn pulls the pull rope of the generator 34, thus enabling the generator 34 to move.

[0088] Meanwhile, the photovoltaic panel 36 captures solar energy for photovoltaic power generation.

[0089] Specifically, the first connecting base plate 1 and the second connecting base plate 20 are fixed on the concrete base plate set in the river channel. The water in the river channel is filtered by the second flange plate 3 first, blocking the debris in the water flow. Some water flows to the impeller 14 after passing through the rectifier port 8. The water flow drives the impeller 14 to rotate. Multiple impellers 14 on the same circular sliding rail 11 also rotate synchronously under the cooperation of the chain 39 and the sprocket on the outer connecting shaft 38.

[0090] During the rotation of impeller 14, impeller 14 drives drive gear 21 and mating gear disk 19 to rotate in the same direction via drive shaft. If mating gear 22 meshes with drive gear 21 first and then with mating gear disk 19, or if mating gear 22 meshes with mating gear disk 19 first and then drive gear 21 meshes, the drive gear 21 drives turbine 25 to rotate a certain number of revolutions around its axis in one direction, and then the rotation direction switches, and turbine 25 rotates a certain number of revolutions around its axis in the other direction. In both rotation directions, turbine 25 rotates around... The number of rotations in its axial direction is determined by setting the gear ratio of the driving gear 21, the mating gear disk 19, and the mating gear 22. After the worm gear 25 drives the worm shaft 26 to rotate a certain number of times around its axial direction, the worm shaft 26 then rotates a certain number of times in another direction (opposite to the previous rotation direction) around its axial direction. The number of rotations of the worm shaft 26 around its axial direction is the same in both rotation directions. The worm shaft 26 drives the transmission rack 16 to reciprocate on the sliding table 27. The end of the transmission rack 16 is pulled... The generator traction rope 7 reciprocates to pull the pull rope of the generator 34, enabling the generator 34 to continuously generate electricity. During the power generation process, the second limiting plate 171 connected to the cross-shaped connecting plate 18 cooperates with the second limiting wheel 33 to form a stable support point, allowing the generator traction rope 7 to stably pull the pull rope of the generator 34. When the transmission rack 16 pulls the pull rope of the generator 34 out in one direction through the generator traction rope 7, the meshing relationship between the drive gear 21 or the meshing gear 19 and the meshing gear 22 changes, causing the transmission rack 16 to move in another direction (this direction is opposite to the previous direction in which the transmission rack 16 pulled the generator traction rope 7, so the position of the transmission rack 16 changes to: first returning to the initial position, and then continuing to move along the direction of movement when returning to the initial position). During this process, the pull rope of the generator 34 will be retracted to the initial state under its own structural action, and then pulled out again by the transmission rack 16 through the generator traction rope 7. This process repeats, enabling the generator 34 to continuously generate electricity.
