Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning, and in particular to a self-cleaning photovoltaic panel. Background Technology

[0002] Currently, during long-term use, photovoltaic panels easily accumulate dust, leaves, and other debris on their surface. This debris affects the absorption of light energy by the photovoltaic panels and reduces power generation efficiency, thus requiring regular cleaning. Traditional cleaning methods are costly and inefficient. While automatic cleaning equipment can reduce labor costs, it usually consumes additional water resources, making it difficult to promote in water-scarce areas. Most existing photovoltaic equipment lacks effective utilization of rainwater, using rainwater only as a natural flushing method, and cannot collect, filter, or store rainwater, let alone recycle it for cleaning photovoltaic panels.

[0003] This self-cleaning photovoltaic panel can collect rainwater, filter it initially, and store it. When the surface of the photovoltaic panel needs cleaning, a high-pressure water pump is activated to rinse and clean the surface. Some of the water from the rinsing can be filtered again and returned to the circulating water tank, effectively solving the above problems. Utility Model Content

[0023] In the preferred embodiment, the circulating water tank 4 includes an outer shell 402, and an inlet pipe 401 is provided on one side of the outer shell 402. The inlet pipe 401 is connected to the water guide channel 105. The outer casing 402 has a water tank inside, and a removable fine sieve plate 405 is provided above the water tank. The fine sieve plate 405 has a high-density filter screen for filtering fine sand particles.

[0024] In the preferred embodiment, a water inlet plate 406 is provided at the bottom of the water tank, which guides the water flow to the outlet. A high-pressure water pump 407 is provided below the outlet, which pumps water to the outlet pipe 403. The outlet pipe 403 is connected to the spray pipe 404.

[0025] In the preferred embodiment, the water spray pipe 404 has multiple small holes on the side facing the photovoltaic panel 2, and the water spray pipe 404 is used to spray water onto the photovoltaic panel 2 for cleaning the photovoltaic panel 2.

[0027] The detailed operation mode of a self-cleaning photovoltaic panel is as follows: When the background monitoring system detects that the power generation efficiency of the upper photovoltaic panel 201 is lower than the preset threshold due to sand and dust covering it, it sends a cleaning command to the controller. The controller activates the high-pressure water pump 407 at the bottom of the circulating water tank 4. The high-pressure water pump 407 draws water from the bottom of the water tank through the water inlet plate 406, increases the water pressure, and pumps it into the outlet pipe 403. The water flow is transported along the outlet pipe 403 to the spray pipe 404 on the top of the upper photovoltaic panel 201. The spray pipe 404 forms a fan-shaped water curtain through the small holes, which washes the surface of the upper photovoltaic panel 201. The sand and dust mixed with water flow downwards along the surface of the upper photovoltaic panel 201. When it passes through the intermediate sieve hopper 3, the sieve holes 305 of the sieve plate 304 intercept large particles of debris such as leaves. The water that has been initially filtered continues to flow through the surface of the lower photovoltaic panel 202 and finally flows into the water guide trough 105 below the lower photovoltaic panel 202. The stainless steel mesh 107 at the top of the water guide trough 105 performs secondary interception, and the slope 108 guides the water flow into the inlet pipe 401. After water flows through the inlet pipe 401 into the circulating water tank 4, it undergoes fine filtration via the fine screen plate 405 above the tank. The filtered clean water then re-enters the tank to complete the circulation process. The entire process is automated, from monitoring to cleaning to recycling, effectively improving the cleaning effect and power generation efficiency of the photovoltaic panels.
