Description

Technical Field

[0001] The present application relates to the field of photovoltaic panel cleaning, and in particular to a photovoltaic cleaning robot. Background Art

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). In order to ensure the power generation efficiency of the photovoltaic panel, the surface needs to be kept clean. Dust accumulated over a long period of time will affect the power generation efficiency of the photovoltaic panel. Related technologies use a method of installing cleaning robots on the photovoltaic panels in sequence to regularly clean the surface of the photovoltaic panels.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the cleaning robot can only clean a single photovoltaic panel. The cost of setting up a cleaning robot for a single photovoltaic panel is high. At the same time, the cleaning robot will affect the normal lighting of the photovoltaic panel when it stops working.

[0007] By adopting the above technical solution, the operator arranges the device at the gap position of a single row of photovoltaic panels close to another row of photovoltaic panels. When the device is in the initial state, the second support frame finally corresponds to the axis of the first support frame, and the cylinder contracts so that the device is lower than the position of the photovoltaic panel. When the cleaning roller brush is needed for cleaning, the first drive component drives the sliding seat to move to the position of the photovoltaic panel that needs to be cleaned, and the first control component drives the first support frame to rotate along the connection between it and the sliding seat so that the second support frame is parallel to the photovoltaic panel, and then the second drive component drives the second support frame to move so that the second support frame and the cleaning roller brush move to the top of the photovoltaic panel, and the third drive component drives the mounting seat to move, and the mounting seat moves so that the cleaning roller brush moves to clean the surface of the photovoltaic panel; by setting the sliding seat and the second support frame, when the cleaning roller brush is not working, the second support seat moves to the gap position of the photovoltaic panel to prevent the device from affecting the lighting of the photovoltaic panel. At the same time, the sliding seat can drive the cleaning roller brush to move at multiple photovoltaic panel positions, thereby achieving the effect of a single cleaning roller brush responsible for the cleaning of multiple photovoltaic panels. The first control component helps the second support frame change its angle to help the cleaning roller brush adapt to photovoltaic panels of different angles.

[0015] By adopting the above technical solution, when it is necessary to adjust the moving angle of the second support frame and the cleaning roller brush, the second motor is started, and the second motor drives the first spur gear to rotate. The rotation of the first spur gear causes the crown gear to rotate.

[0047] The implementation principle of a photovoltaic cleaning robot in an embodiment of the present application is as follows: an operator arranges the device at a gap position between a single row of photovoltaic panels and another row of photovoltaic panels.

The support frame 23 and the cleaning roller brush 1 move to the top of the photovoltaic panel, and the third driving component 5 drives the mounting seat 24 to move. The movement of the mounting seat 24 allows the cleaning roller brush 1 to move to clean the surface of the photovoltaic panel. By setting the sliding seat 21 and the second support frame 23, when the cleaning roller brush 1 is not working, the second support frame moves to the gap position of the photovoltaic panel to prevent the device from affecting the lighting of the photovoltaic panel. At the same time, the sliding seat 21 can drive the cleaning roller brush 1 to move at multiple photovoltaic panel positions, thereby achieving the effect of a single cleaning roller brush 1 being responsible for the cleaning of multiple photovoltaic panels.
