[0018] Example 1 like Figure 1-5 As shown, the integrated water-photovoltaic energy storage and power generation device includes: two diversion plates 2 with their ports inclined relative to each other; two water collection tanks with their tops located at the ports of the diversion plates 2, one of which is used to prevent rainwater overflow, and the two water collection tanks are connected to each other; the top of the power generation tank and the lower end of the side wall of the other water collection tank are connected in series, the power generation tank is equipped with a filter and a water turbine generator 13, the filter is spaced at the bottom of the power generation tank, the water turbine generator 13 is used to generate electricity under the flushing of water, and the inner walls of the power generation tank are respectively equipped with fixing plates 560, the fixing plates 560 are detachably connected to the filter; the upper end of the side wall of the pressure water supply tank 14 and the lower end of the side wall of the power generation tank are connected in series, the pressure water supply tank 14 is used to store filtered water, and a conveying system 15 is provided inside it.

[0019] Furthermore, two relatively inclined diversion plates 2 effectively expand the water collection area and guide rainwater to flow in a concentrated manner. Two collection tanks are located below the outlet of the diversion plates to collect rainwater. One collection tank prevents rainwater overflow during heavy rainfall. The lower ends of the side walls of the two collection tanks are connected by pipes to achieve water level balance and capacity complementarity. The lower end of the side wall of one of the collection tanks is connected to the top of the power generation tank. Water flows into the power generation tank through a pipe and drives the turbine generator 13. The water driven by the turbine generator 13 is filtered by a filter. The filter is installed inside the tank and connected to the bottom of the power generation tank at intervals by fixing plates 560. It effectively intercepts sediment and impurities, allowing the water to smoothly enter the next stage after passing through the filter. The filter is bolted to the fixing plates 560, allowing for easy replacement of the filter when damaged. The lower end of the side wall of the power generation tank is connected to the upper end of the pressure water supply tank 14, and the filtered water flows into the pressure water supply tank 14. The container is equipped with a conveying system 15, which can pressurize and deliver water to irrigation, flushing, and other water use points or to another container for storage, as needed. The entire system integrates diversion, water collection, filtration, hydropower generation, and pressurized water supply. Through a multi-stage series design, it achieves efficient collection, purification, utilization, and energy recovery of rainwater, improving resource utilization efficiency and providing good energy-saving and environmental benefits.

[0020] Two diversion plates 2 are inclined at their ports and mounted on a support frame 101. A photovoltaic panel 1 is fixed at an incline on the top of the support frame 101. Each diversion plate 2 is provided with a diversion groove 201.

[0021] Furthermore, the two drainage plates 2 are fixedly installed via support frames 101, with their outlet ports arranged at relative inclinations to form a converging and guiding structure. This facilitates the centralized guidance of rainwater to the collection area, improving drainage efficiency and preventing overflow. Each drainage plate 2 has a drainage groove 201 extending along its length. The groove design conforms to fluid mechanics principles, efficiently collecting rainwater or snowmelt and guiding it to the designated drainage area, preventing lateral overflow or dust accumulation. The photovoltaic panel 1 is fixedly installed at an inclined angle on the support frame 101, facilitating exposure to sunlight and the conversion of light into electricity for storage.

[0022] The water collection tank includes a first water collection tank 3 and a second water collection tank 4 arranged side by side. The lower end of the side wall of the first water collection tank 3 is provided with a pipe that communicates with the second water collection tank 4. The bottom of the second water collection tank 4 is inclined towards the pipe connection.

[0023] Furthermore, the water collection tank consists of a first water collection tank 3 and a second water collection tank 4 arranged side by side. The two are connected by a pipe located at the lower end of the side wall of the first water collection tank 3, facilitating water flow from the first water collection tank 3 to the second water collection tank 4. To improve drainage efficiency, the bottom of the second water collection tank 4 is designed with a sloping structure that slopes towards the pipe connection, allowing accumulated water to naturally collect at the pipe inlet under gravity, effectively preventing water stagnation. This structure optimizes the water collection and drainage process, enhances the system's self-cleaning capability, and is suitable for applications with high drainage performance requirements, ensuring stable and reliable operation.

[0024] The power generation tank includes a first power generation tank 5 and a second power generation tank 6 arranged in a staggered manner. The lower end of the side wall of the first power generation tank 5 and the upper end of the side wall of the second power generation tank 6 are connected in series. The top of the first power generation tank 5 and the lower end of the side wall of the first water collection tank 3 are connected in series.

[0025] Furthermore, the first collection tank 3 and the first power generation tank 5 are connected in series. The power generation tank consists of the first power generation tank 5 and the second power generation tank 6, which are arranged in a staggered manner to optimize space utilization and water flow path. The lower end of the side wall of the first power generation tank 5 and the upper end of the side wall of the second power generation tank 6 are connected in series by a pipe, so that the water flows from the bottom of the first power generation tank 5 into the upper part of the second power generation tank 6 naturally, forming a step-by-step flow guide, effectively utilizing the water level difference, improving water energy utilization efficiency, and ensuring the stable operation of the power generation system.

[0026] The conveying system 15 includes an electromagnetic hydraulic rod 1502 with a push plate 1501 fixedly connected to the top and an electromagnetic valve 1503 fixedly connected to the bottom. The top of the electromagnetic hydraulic rod 1502 and the push plate 1501 are located in the pressure water tank 14, and the sides of the push plate 1501 are provided with sealing sleeves.

[0027] Furthermore, the conveying system 15 mainly consists of an electromagnetic hydraulic rod 1502, a push plate 1501, and a solenoid valve 1503. The push plate 1501 is fixedly connected to the top of the electromagnetic hydraulic rod 1502 and extends into the pressure water tank 14. A sealing sleeve is provided on the side of the push plate 1501 to ensure a tight fit with the inner wall of the tank, preventing leakage and pressure loss. The solenoid valve 1503 is connected to the bottom of the electromagnetic hydraulic rod 1502 for precise control of hydraulic movements. This structure drives the push plate to reciprocate through electronic control, achieving stable pressurization and quantitative delivery of water, improving the system's automation level and operating efficiency. A water level sensor is installed at the upper end of the inner wall of the pressure water tank 14. When the water level reaches a certain height, the water level sensor transmits a signal to the central controller, which then transmits the signal to the solenoid valve 1503.

[0028] The upper side wall of the pressure water tank 14 is provided with a first connecting pipe 701 and a second connecting pipe 1401, and both the first connecting pipe 701 and the second connecting pipe 1401 are provided with a one-way check valve 16.

[0029] Furthermore, the upper side wall of the pressure water tank 14 is respectively equipped with a first connecting pipe 701 and a second connecting pipe 1401, both of which are equipped with one-way check valves 16 to ensure unidirectional flow of the medium. The one-way check valves 16 can prevent backflow caused by pressure fluctuations or system shutdown, ensuring the stability of the delivery. The first connecting pipe 701 and the second connecting pipe 1401 are respectively connected to different functional units.

[0030] The other end of the first connecting pipe 701 is connected to the high-level water storage tank 7, and the other end of the second connecting pipe 1401 is connected to the second power generation water tank 6.

[0031] Furthermore, the other end of the first connecting pipe 701 is connected to the high-level water storage tank 7. When the water level sensor detects that the water in the pressure water supply tank 14 is full, the solenoid valve 1503 is activated, causing the electromagnetic hydraulic rod 1502 to drive the push plate 1501 upward, thereby transporting the water in the pressure water supply tank 14 to the high-level water storage tank 7 for later use. The one-way check valve 16 provided on the first connecting pipe 701 can prevent the water in the high-level water storage tank 7 from flowing back. The one-way check valve 16 provided on the second connecting pipe 1401 can prevent the water in the pressure water supply tank 14 from flowing back into the second power generation water tank 6. The two connections respectively undertake the functions of replenishment and water storage, optimize the overall energy efficiency of the system, realize the cascade utilization of water resources and energy recycling, and improve the stability and sustainability of equipment operation.

[0032] Both the first power generation water tank 5 and the second power generation water tank 6 are equipped with inclined diversion panels 8, with the downward inclined end of the diversion panels 8 aligned with the turbine generator 13.

[0033] Furthermore, both the first power generation tank 5 and the second power generation tank 6 are equipped with inclined diversion panels 8. The first water collection tank 3 is connected to the first power generation tank 5 via a pipe. Water flowing out of the pipe passes through the diversion panels 8 in the first power generation tank 5, which guide the water flow to concentrate and directionally impact the turbine generator 13. The water then passes through a filter and flows into the second power generation tank 6. The first power generation tank 5 is connected to the second power generation tank 6 via a pipe, and the structure of the second power generation tank 6 is the same as that of the first power generation tank 5. Therefore, the water passes through the turbine generator 13 and the filter twice, improving the water utilization rate and purity.

[0034] The first power generation water tank 5 and the second power generation water tank 6 are inclinedly provided with a flow guiding and accelerating plate 9. The flow guiding and accelerating plate 9 and the flow guiding inclined plate 8 are arranged at intervals and form an included angle.

[0035] Furthermore, both the first power generation tank 5 and the second power generation tank 6 are equipped with inclined flow-guiding and accelerating plates 9, which are arranged at intervals with the flow-diverting inclined plates 8 and form a certain angle. This structure can guide and accelerate the water flow in multiple stages, causing the water to generate a focusing effect as it passes through, further increasing the flow velocity and impact force. The flow-guiding and accelerating plates 9 and the flow-diverting inclined plates 8 work together to optimize the water flow direction, reduce energy loss, effectively enhance the driving effect on the impeller of the hydro-generator 13, and significantly improve the water energy utilization efficiency and the overall power generation performance of the system.

[0036] The filter element includes a filter layer 12 located between a first filter plate 10 and a second filter plate 11, and a water turbine generator 13 and the first filter plate 10 are spaced apart.

[0037] Furthermore, the filter element consists of a first filter plate 10, a second filter plate 11, and a filter layer 12 sandwiched between them, forming a multi-layer composite filtration structure that effectively intercepts suspended solids and impurities in the water, ensuring the cleanliness of the system water. The filter layer 12 can be made of porous materials, fiber media, activated carbon, or other chemical substances to improve filtration efficiency.

[0038] Example 2 The flow-guiding and accelerating plate 8 and the flow-inducing inclined plate 8 form a funnel-shaped space, with the larger opening facing upstream of the water flow and the smaller opening facing downward towards the special water turbine generator 13. This design can concentrate the water flow. According to V=Q / A, it can be deduced that the speed of the water flow increases sharply when it passes through the flow-guiding and accelerating plate 9, and the kinetic energy increases accordingly. The water flow flowing out from below the flow-guiding and accelerating plate 9 impacts the impeller of the water turbine generator 13 at high speed, achieving high-efficiency power generation.

[0039] Rainwater passes through two filtration devices. Both stages of the power generation tanks employ two different filtration methods. This two-layer filtration avoids the inherent surface clogging and limited filtration speed of heterogeneous filter beds. The device uses two filter plates: the first filter plate 10 has large pores, and the second filter plate 11 has small pores. The first filter plate 10 primarily filters larger particles. Activated carbon and other porous materials are placed between the first filter plate 10 and the second filter plate 11 to facilitate water purification.

[0040] The pressure water supply tank 14 mainly consists of a push plate 1501, an electromagnetic hydraulic rod 1502, and a solenoid valve 1503. Filtered water flows into the pressure water supply tank 14 through a pipe. The push plate 1501, the same size as the inner wall of the tank, is placed inside. A sealing sleeve is added around the push plate 1501 to prevent water from seeping downwards. The electromagnetic hydraulic rod 1502 is connected below the push plate 1501. The telescopic part of the electromagnetic hydraulic rod 1502 passes through the bottom of the pressure water supply tank 14 and connects to a three-way water pipe below. Two load solenoid valves are installed at its other two ends to control the water flow direction. The solenoid valve 1503 is a load solenoid valve. When the pressure water tank 14 is collecting water, both solenoid valves 1503 are closed. When the water tank is full, the valve connecting the pressure water tank 14 to the generator water tank is closed. When the load solenoid valve at the left end of the three-way water pipe is open and the unloading solenoid valve at the right end is closed, tap water or other water sources are introduced, causing the push plate 1501 to rise, lifting the water stored in the pressure water tank 14 and allowing it to flow into the high-level water storage tank 7 through the one-way check valve pipeline for storage. When the load solenoid valve at the left end of the three-way pipe is closed and the unloading solenoid valve at the right end is open, the electromagnetic hydraulic rod 1502 drives the push plate 1501 to descend, returning to its initial position. The high-level water storage tank 7 is where water is delivered to the pressure water tank 14 by the electromagnetic hydraulic rod 1502 and the push plate 1501 for storage, and can be used for agricultural and livestock production or daily life.

[0041] The implementation principle of this embodiment is as follows: Rainwater flowing over the photovoltaic panel 1 is effectively collected by the diversion plate 2, and then diverted into the first collection tank 3 and the second collection tank 4 through a diversion structure, achieving efficient collection of initial rainwater. The collected rainwater flows into the first power generation tank 5 and the second power generation tank 6, and passes sequentially through the inclined diversion plate 8 and the flow acceleration plate 9, achieving water flow guidance and kinetic energy enhancement, concentrating the impact on the impeller of the water turbine generator 13, driving it to rotate and generate electricity. The generated electricity is transmitted through cables and stored in lithium batteries, achieving energy recovery and utilization. After flowing through the water turbine generator 13, the rainwater undergoes multi-stage purification treatment through filters (including the first filter plate 10, the second filter plate 11, and the intermediate filter layer 12) to remove impurities, ultimately realizing the collection, power generation, filtration, and resource storage of rainwater, constructing an efficient and sustainable rainwater energy integrated utilization system.

The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
