[0049] In order to show the experimental data and embodiments of the present invention, the following are some experimental tables and embodiment contents:

[0050]

[0051]

[0052] The photovoltaic panel cleaning robot of the present invention combines a precise adjustment mechanism, an intelligent cleaning function and efficient water source control, and can clean different types of photovoltaic panels in a variety of environments, and ensure that the cleaning process is efficient, uniform and damage-free. Although slight scratches may appear on some heavily contaminated photovoltaic panels, the overall cleaning effect is still excellent, and the high degree of automation of the robot significantly reduces manual intervention and maintenance costs, and improves the overall cleaning efficiency and maintenance effect of the photovoltaic panels.

[0053] The following is an example to illustrate how to implement the invention in practical applications.

[0054] Example 1.1

[0055] Scenario description: The robot arm of the present invention is used to clean the monocrystalline silicon photovoltaic panel installed on the roof. The photovoltaic panel is installed at a height of about 5 meters on the roof, and the surface is covered with dust and a small amount of water stains. The operator makes appropriate adjustments according to the surface condition of the photovoltaic panel and uses the robot arm to clean the photovoltaic panel.

[0056] Operation steps: The operator moves the manipulator body to the side of the photovoltaic panel, adjusts the position of the cleaning roller brush by adjusting the sleeve to ensure that the roller brush can fit the surface of the photovoltaic panel, and uses the electric adjustment rod and electric push rod to accurately adjust the height and tilt angle of the mounting frame through the adjustment mechanism to adapt to the different heights and tilt angles of the photovoltaic panel. The cleaning roller brush starts to rotate, and the gear and rack mesh to drive the transmission rod to rotate, thereby driving the cleaning roller brush to clean. Water drips to the cleaning roller brush through the transmission pipe to reduce friction and avoid damage to the surface of the photovoltaic panel. After 10 minutes of cleaning, the dust and water stains on the surface of the photovoltaic panel are completely removed, and there are no scratches or other damage on the surface.

[0057] Example 1.2

[0058] Scenario description: The robot arm of the present invention is used to clean the polycrystalline silicon photovoltaic panels on the roof of a commercial building. There are oil stains and pollutants on the surface of the photovoltaic panels, and the cleaning is required to be efficient and damage-free.

[0059] Operation steps: The robot body moves to the top of the photovoltaic panel, and the electric adjustment rod is used to adjust the height of the cleaning roller brush and ensure that it is in good contact with the surface of the photovoltaic panel. The electric push rod drives the limiter to rotate to ensure that the inclination angle of the mounting frame adapts to the angle of the photovoltaic panel. Water drips onto the surface of the cleaning roller brush through the water tank and the transmission pipe, and the cleaning roller brush starts to rotate. When the robot moves on the photovoltaic panel, the cleaning roller brush effectively removes the oil on the surface. After cleaning, the oil and pollutants on the surface of the photovoltaic panel are completely removed without any scratches or damage.

[0060] Working principle: The working principle of the present invention is that the cooperation of the precise cleaning mechanism 2 and the adjustment mechanism 3 enables the manipulator body 4 to efficiently and stably complete the cleaning task of the photovoltaic panel body 1. First, the user can adjust the position of the manipulator body 4, move it to the photovoltaic panel body 1, and then adjust the position of the cleaning roller brush 206 by adjusting the sleeve 208. The adjusting sleeve 208 drives the transmission plate 208 to rotate, and then adjusts the position of the adjustment plate 215. The adjustment plate 215 drives the return spring 211 and the fixed plate 207 to move, so as to adjust the cleaning pressure according to the surface shape of the photovoltaic panel body 1 to ensure that the cleaning process is uniform and avoid excessive cleaning to cause damage to the surface of the photovoltaic panel body 1. During cleaning, the manipulator body 4 drives the mounting frame 202 to move along the top of the photovoltaic panel body 1. When the gear 204 is engaged with the rack 201, it drives the transmission rod 213 to rotate. The cleaning roller 206 is driven to rotate, thereby driving the cleaning roller brush 206 to rotate. The water in the water tank 203 drips onto the surface of the cleaning roller brush 206 through the transmission pipe 205, reducing friction and avoiding scratching the surface of the photovoltaic panel body 1. At the same time, the adjustment mechanism 3 accurately adjusts the height of the mounting frame 202 through the electric adjustment rod 302 to adapt to photovoltaic panel bodies 1 of different heights, and drives the limit member 301 to rotate through the electric push rod 304 to adjust the inclination angle of the mounting frame 202 and optimize the cleaning effect. The connection between the limit frame 306 and the rotating shaft 305 enhances the stability during the adjustment process and avoids the influence of instability on the cleaning effect. The overall design improves the adaptability, stability and cleaning efficiency of the manipulator body 4, reduces manual intervention, ensures the quality and accuracy of each cleaning, thereby improving the automation level of the cleaning process and optimizing the maintenance effect of the photovoltaic panel body 1.
