Description

Technical Field

[0001] This utility model relates to a marine photovoltaic rainwater collection and cleaning device. Background Technology

[0002] Photovoltaic modules are installed outdoors, and fine dust particles and snow adhering to their surfaces can affect light transmittance, thus affecting the amount of radiation received by the module surface and impacting power generation efficiency. Stains, bird droppings, and other localized obstructions can cause hot spots on the photovoltaic modules, reducing power generation efficiency or even burning them out. To improve the power generation efficiency of photovoltaic modules, regular cleaning is necessary.

[0003] Traditional methods for cleaning photovoltaic (PV) modules include manual cleaning, high-pressure water gun cleaning, automatic spray system cleaning, professional cleaning vehicle cleaning, and robotic cleaning. These methods are all used in onshore PV module cleaning, but their application at sea presents the following problems: seawater is corrosive and cannot be used directly for module cleaning; obtaining water for offshore cleaning is difficult; offshore PV modules are at higher elevations, making manual cleaning dangerous; offshore PV areas are large and have many arrays, resulting in a large workload, and manual or ship-based cleaning is time-consuming and expensive; robotic cleaning is limited by the robot's own battery capacity, limiting its cleaning capabilities; PV module cleaning needs to be carried out at night or during periods of low sunlight, making ship-based and manual cleaning difficult and the cleaning effect unreliable.

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, a marine photovoltaic rainwater collection and cleaning device includes a water collection tank 1, a water collection pipe 2, a water storage tank 3, a fixed water supply pipe 4, an operation and maintenance platform 5, a water pump 6, a turntable 7, a water supply hose 8, and a cleaning robot 9. The water collection tank 1 is connected to the lower end of an inclined photovoltaic panel support 10. The water collection tank 1 is located below the photovoltaic panel support 10, with an open upper end and a certain slope at the bottom. The upper end of the photovoltaic panel support 10 is connected to the operation and maintenance platform 5. A slope 15 is provided between the operation and maintenance platform 5 and the photovoltaic panel support 10 for the cleaning robot 9 to move onto the operation and maintenance platform 5. When the cleaning robot 9 is not working, it moves onto the operation and maintenance platform 5 via the slope 15.

[0024] Specifically, a water pump 6 is installed on the maintenance platform 5. One end of the water pump 6 is connected to the cleaning robot 9 via a water supply hose 8, which is wound around a turntable 7. The turntable 7 is rotatably connected to the maintenance platform 5, and a return spring is connected to its lower end, which can automatically rotate and retract the water supply hose 8. The water storage tank 3 is connected to the lower end of the photovoltaic panel bracket 10, and the water collection tank 1 is connected to the water storage tank 3 via a water collection pipe 2. The lower end of the water collection tank 1 is provided with a water outlet, which is connected to the water collection pipe 2 via a three-way water collection pipe valve 11. The other end of the water storage tank 3 is connected to the water pump 6 via a fixed water supply pipe 4.

[0025] Specifically, the operation and maintenance platform 5 is also equipped with a power supply device 14, and the water pump 6 and the cleaning robot 9 are electrically connected to the power supply device 14 to drive the water pump 6 and the cleaning robot 9 to work.

[0026] Specifically, a water supply connector 12 is connected to the water storage tank 3. When the water in the water storage tank 3 is insufficient to meet the needs of the next cleaning, the ship will fill the water storage tank 3 with water through the water supply connector 12 on the side of the water storage tank 3.

[0027] Specifically, there can be two or more water storage tanks 3. Each of the two water storage tanks 3 is connected to a fixed water supply pipe 4. The water pump 6 is connected to two fixed water supply pipes 4 through a three-way water supply valve 13. In use, the three-way water supply valve 13 can open the valve corresponding to the water storage tank with sufficient water and close the valve corresponding to the water storage tank with insufficient water.

[0028] Specifically, during rainfall, rainwater falling on the photovoltaic panel support 10 will collect in the water collection trough 1 on the underside of the photovoltaic modules due to the tilt slope of the modules, and then enter the water collection pipe 2 through the outlet hole. Initially, the valve (three-way water collection pipe valve 11) of the water collection pipe 2 is open, and rainwater carrying some dirt from the photovoltaic modules will be directly discharged into the sea. When the sewage discharge reaches a certain flow rate, the outward drainage valve is closed, and the valve leading to the water storage tank 3 is opened. At this time, the rainwater flowing into the water storage tank 3 is relatively clean rainwater. When the water volume in the water storage tank is insufficient to meet the next cleaning needs, water can be supplied to the side of the water storage tank 3 through the water inlet 12 from the ship. Water is added to the water storage tank. When the components need cleaning, the water pump 6 on the maintenance platform 5 starts working, pumping the water in the water storage tank 3 to the maintenance platform 5 through the fixed water supply pipe 4. After the cleaning robot 9 is connected to the water supply hose 8 through the reserved interface, it runs from the reserved slope 15 of the maintenance platform 5 to the top of the components and begins to clean them. As the cleaning robot 9 moves, the turntable 7 automatically retracts and extends the water supply hose 8 to ensure that the cleaning robot 9 can clean the entire array, while the water supply hose 8 does not obstruct the movement of the cleaning robot 9. After cleaning is completed, the cleaning robot 9 returns to the maintenance platform 5, and the turntable 7 retracts the water supply hose 8.

[0029] This offshore photovoltaic rainwater collection and cleaning device integrates functions such as water collection, storage, supply, and cleaning. It can collect and store rainwater and use it for the cleaning work of the photovoltaic cleaning robot, solving the problem of difficulty in obtaining water sources for cleaning offshore photovoltaic modules. The three-way water collection pipe valve 11 prevents dirty rainwater from directly entering the water storage tank 3. The water supply connector 12 of the water storage tank 3 can serve as an overflow outlet when the tank is full, or as an interface for external water replenishment in the event of a long period without rain. The turntable 7 on the maintenance platform 5 can adjust the length of the water supply hose 8 according to the position of the cleaning robot 9 to ensure the cleaning range while ensuring that the water supply hose does not affect the operation of the cleaning robot. The power supply device 14 on the maintenance platform can utilize the electricity stored in the photovoltaic array to power the cleaning robot and water pump.
