Description

Technical Field

[0001] This utility model belongs to the technical field of photovoltaic module cleaning devices, specifically relating to a water-saving intelligent cleaning device for photovoltaic modules. Background Technology

[0002] Photovoltaic modules are exposed to the outdoors for a long time, and their surfaces are prone to accumulating dust, dirt and other impurities, which affects power generation efficiency. Therefore, they need to be cleaned regularly. When cleaning the dust on the inclined surface of photovoltaic modules using a cleaning device, the cleaning disc along with the cleaning liquid is flushed onto the surface of the module and wiped clean by the cleaning disc to achieve the cleaning effect. However, there are the following defects: (1) In the existing photovoltaic module cleaning device, clean water is usually used directly to rinse and clean the surface of the photovoltaic module during the cleaning process. Most of the wastewater generated during cleaning is directly discharged without effective recycling, which leads to the problem of water waste. Therefore, we propose a water-saving intelligent photovoltaic module cleaning device. Utility Model Content

[0003] The purpose of this invention is to provide a water-saving intelligent cleaning device for photovoltaic modules to solve the problem of water waste in cleaning devices mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water-saving intelligent cleaning device for photovoltaic modules, comprising a cleaning chamber, wherein a water tank and a machine compartment are respectively arranged inside the cleaning chamber, and a first water pump and a second water pump are respectively installed inside the machine compartment. The water inlet of the second water pump is connected to a water injection rod through a pipe, and a cleaning disc is installed at the water outlet of the water injection rod. A connecting component is fixed to the surface of the water injection rod, and a recycling box is fixed to one end of the connecting component. One end of the recycling box is connected to the water inlet of the first water pump through a pipe. The water outlet of the first water pump and the water inlet of the second water pump are respectively connected to the interior of the water tank, and water collection plates are fixed on both sides of the recycling box.

[0005] Preferably, the connecting assembly consists of a connecting cylinder and a connecting column. The connecting cylinder is sleeved on the outer wall of the connecting column, one end of the connecting column is fixed to the recycling box, and one end of the connecting cylinder is fixed to the surface of the water injection rod.

[0006] Preferably, the side wall of the connecting column is provided with a limiting groove, and a limiting block is provided inside the limiting groove. The limiting block is fixed on the inner wall of the connecting cylinder.

[0007] Preferably, a top spring is provided at the other end of the connecting column, and the top spring is located inside the connecting cylinder.

[0008] Preferably, a filter plate is installed at the port of the recycling box.

[0009] Preferably, the water collection plate has an arc-shaped cross-section, and the height of the water collection plate is equal to the height of the recycling box.

[0010] Preferably, a rubber pad is fixed to the end face of the water collection plate and the recycling box, and the cross-section of the rubber pad is an arc-shaped structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) Through the designed recycling box, water collection plate, connecting components, and first water pump, wastewater generated by washing and cleaning the surface of the tilted photovoltaic module flows along the tilted surface. During the flow, the water collection plate intercepts and collects the wastewater, which then flows into the recycling box. The first water pump then pumps the wastewater in the recycling box into the water tank, achieving water recycling and water saving. The designed limiting blocks and limiting grooves limit the movement of the connecting column, preventing the integrated structure of the recycling box and water collection plate from detaching from the water injection rod. The designed top spring controls the movement of the connecting column. The column applies elastic compression, which in turn pushes the integrated structure consisting of the recycling box and the water collection plate to fit more tightly against the surface of the photovoltaic module. This prevents the cleaning wastewater from flowing out from the gaps between the two surfaces when it is concentrated, thus reducing the amount of wastewater recycled. The designed filter plate filters the recycled water, filtering out impurities and preventing blockage of the recycling pipeline that would affect the water recycling efficiency. The designed rubber pad ensures that the water collection plate and recycling box fit more tightly against the surface of the photovoltaic module when cleaning the photovoltaic module, further improving the water collection and recycling effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a water-saving intelligent cleaning device for photovoltaic modules, including a cleaning housing 1. The cleaning housing 1 has a water tank 2 and a machine compartment 5 inside. A first water pump 3 and a second water pump 4 are installed inside the machine compartment 5. The water inlet of the second water pump 4 is connected to a water injection rod 6 via a pipe. A cleaning disc 9 is installed at the water outlet of the water injection rod 6. A connecting component 11 is fixed to the surface of the water injection rod 6. A recycling box 7 is fixed to one end of the connecting component 11. One end of the recycling box 7 is connected to the water inlet of the first water pump 3 via a pipe. The water outlet of the first water pump 3 and the water inlet of the second water pump 4 are both connected to the interior of the water tank 2. Both sides of the recycling box 7 are fixed... A water collection plate 8 is provided. The connecting component 11 consists of a connecting cylinder 13 and a connecting column 12. The connecting cylinder 13 is sleeved on the outer wall of the connecting column 12. One end of the connecting column 12 is fixed to the recycling box 7. Through the designed recycling box 7, water collection plate 8, connecting component 11 and first water pump 3, the wastewater generated by washing and cleaning the surface of the tilted photovoltaic module flows along the tilted surface. During the flow, the water collection plate 8 intercepts and collects the wastewater, which then flows into the recycling box 7. The first water pump 3 works to transport the wastewater in the recycling box 7 to the water tank 2, realizing water recycling and achieving water saving. One end of the connecting cylinder 13 is fixed to the surface of the water injection rod 6.

[0021] In this embodiment, preferably, a limiting groove 15 is provided on the side wall of the connecting column 12, and a limiting block 16 is provided inside the limiting groove 15. The limiting block 16 and the limiting groove 15 are designed to limit the movement of the connecting column 12, preventing the integrated structure composed of the recycling box 7 and the water collection plate 8 from detaching from the water injection rod 6. The limiting block 16 is fixed on the inner wall of the connecting cylinder 13. A top spring 17 is provided at the other end of the connecting column 12. The top spring 17 is designed to apply elastic squeezing force to the movable connecting column 12, thereby pushing the contact surface of the integrated structure composed of the recycling box 7 and the water collection plate 8 to fit more tightly with the surface of the photovoltaic module, preventing the wastewater from flowing out from the gap between the two surfaces when the cleaning wastewater is concentrated, thus reducing the amount of wastewater recovered. The top spring 17 is located inside the connecting cylinder 13.

[0022] In this embodiment, preferably, a filter plate 14 is installed at the port of the recycling box 7. The designed filter plate 14 filters the recycled water and filters out the impurities contained in the recycled water, so as to avoid clogging the recycling pipeline and affecting the water recycling efficiency.

[0023] In this embodiment, preferably, the cross-section of the water collecting plate 8 is an arc-shaped structure, and the height of the water collecting plate 8 is equal to the height of the recycling box 7. Rubber pads 10 are fixed to the end faces of the water collecting plate 8 and the recycling box 7. The designed rubber pads 10 ensure that the water collecting plate 8 and the recycling box 7 are more closely attached to the surface of the photovoltaic module when cleaning the surface of the photovoltaic module, thereby further improving the water collection and recycling effect. The cross-section of the rubber pads 10 is an arc-shaped structure.

[0024] The working principle and usage process of this utility model are as follows: The recycling box 7 is installed onto the water injection rod 6 of the cleaning structure via the connecting component 11. A first water pump 3 and a second water pump 4 are installed inside the engine compartment 5. Both the first water pump 3 and the second water pump 4 are model 25SFX4-8-0.25D. The working principle is as follows: When the water pumps start running, the centrifugal force generated by the high-speed rotation of the impeller inside the pumps throws the water in the impeller channel to the surroundings and presses it into the volute. A vacuum is formed at the impeller inlet, and water in the water chamber is drawn in along the suction pipe under external atmospheric pressure to fill this space. The drawn-in water is then thrown out by the impeller, passes through the volute, and enters the outlet for water delivery. When the cleaning device cleans dust and impurities on the surface of the photovoltaic panels of the photovoltaic module, the water injection rod 6 equipped with the cleaning disc is removed... The system starts by placing the cleaning disc 9 on the tilted lower end of the photovoltaic module and reciprocating to clean it. During cleaning, the second water pump 4 operates, delivering the cleaning water in the water tank 2 to the water injection rod 6, and spraying it onto the surface of the photovoltaic module through the outlet of the water injection rod 6, thereby cleaning the photovoltaic module. At the same time, during the cleaning process, the wastewater generated on the tilted photovoltaic module surface after water washing flows along the tilted surface. During the flow, it is intercepted and collected by the water collection plate 8 and flows into the recycling box 7. The filter plate 14 at the port of the recycling box 7 filters the recycled wastewater, filtering out the impurities contained in the recycled water. The first water pump 3 operates to deliver the wastewater in the recycling box 7 to the water tank 2, realizing water recycling and achieving water saving effect.
