Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to a photovoltaic panel cleaning robot. Background Technology

[0002] Photovoltaic power generation, as one of the main forms of solar energy utilization, has developed rapidly in recent years. With the continuous expansion of the construction scale of photovoltaic power plants, the number of photovoltaic panels has increased dramatically. How to ensure the efficient and stable operation of photovoltaic panels to improve power generation efficiency has become a key issue that the photovoltaic industry urgently needs to solve.

[0003] During long-term operation, photovoltaic (PV) panels are inevitably affected by various environmental factors, with the accumulation of dirt such as dust, bird droppings, and leaves being the most common problem. This dirt obstructs the surface of the PV panels, hindering direct sunlight and significantly reducing the efficiency of light energy absorption and conversion. Therefore, regular surface cleaning of PV panels is necessary. However, traditional manual cleaning methods are inefficient, and for large-scale PV power plants, they require a significant investment of manpower and time, with long cleaning cycles, making it difficult to meet the demand for timely cleaning of PV panels.

[0004] Therefore, it is necessary to invent a photovoltaic panel cleaning robot to solve the above problems. Utility Model Content

[0029] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-7 When using this utility model, first, inject an appropriate amount of cleaning water into the water tank 13, then place the entire device onto the photovoltaic panel, and ensure that the robot chassis 1 can move along the preset track on the surface of the photovoltaic panel. Then, the robot chassis 1 is started by the controller 15, which moves along the surface of the photovoltaic panel. While moving, the controller 15 starts the motor 4 and the water pump 14. The motor 4 rotates intermittently in both directions. Through the meshing of the gear 5 and the rack 6, the rack 6 moves back and forth in the guide groove 8 of the guide plate 7. This design enables the brushing assembly 3 to perform sawing brushing operations on the surface of the photovoltaic panel, which is different from the traditional centrifugal brush roller operation and effectively reduces the possibility of sewage splashing. During the brushing process, the water pump 14 draws water from the water tank 13 through the water pipe 17 and delivers it to multiple nozzles 19 arranged in a straight array through the water outlet pipe 18. The water is then sprayed onto the brush bristles 11 through the nozzles 19 to promptly wash away the dirt brushed off, ensuring the cleaning effect. As the robot chassis 1 continues to move, when the wiping component 20 passes over the already swept area, the sponge roller 23 on it wipes away the residual moisture on the surface of the photovoltaic panel, further improving the cleanliness of the photovoltaic panel surface. This series of actions work together to achieve efficient and automatic cleaning of the photovoltaic panel.
