Description

TECHNICAL FIELD

[0001] The utility model relates to the field of solar photovoltaic, especially to a dry type solar panel cleaning robot without water. BACKGROUND

[0002] At present, the photovoltaic power generation industry has developed to a large scale. Solar power generation is to convert light into electricity through the form of light-heat-electricity, that is, to absorb and convert solar radiation through crystalline silicon materials. In the process of using solar energy, the photoelectric conversion efficiency is an important indicator of solar energy utilization, and the dust on the surface of the cell panel will affect the absorption of light radiation by the solar panel, thereby affecting the photoelectric conversion efficiency. Since solar power stations are generally built in remote areas with few people, even in harsh natural desert areas, the cleaning problem of solar panels has become a new research topic.

[0003] The cleaning methods of solar panels in photovoltaic power stations mainly include manual cleaning, mechanical cleaning vehicles and intelligent solar panel cleaning robots. Manual cleaning of solar panels not only wastes water resources, but also has low automation degree and requires a large amount of labor cost. Although the mechanical cleaning vehicle has high automation degree, the vehicle has large size and is not convenient to move, and is easy to damage the photovoltaic panel during cleaning. The existing solar panel cleaning robots are not popular, and the reason is that the design of the cleaning robot's moving range, cleaning efficiency and flexibility does not meet the actual cleaning requirements of the photovoltaic power station.

[0012] 1. The air in the negative pressure cavity is extracted by the rotation of the propeller, thereby generating negative pressure for adsorption, and the thrust generated by the rotation of the propeller is used to attach the robot to the inclined solar panel to move forward, backward, left and right and complete a relatively complete cleaning operation, the fiber soft down material is selected for the roller brush, and the cleaning process of the cleaning robot is to use the roller brush installed in front of the device to preliminarily clean the dust, then use the negative pressure generated by the propeller to suck the cleaned dust into the dust collection box through the dust suction port to complete dust collection, and finally use the bottom cloth to clean the solar panel again, which not only ensures the cleaning efficiency, but also realizes the function of waterless automatic cleaning.

[0013] 2. To ensure that the cleaning robot can move on the solar panel with a certain slope and not damage the solar panel, the power system mainly drives the Mecanum wheel steering by a large torque DC motor, and realizes the climbing ability of 45° slope. BRIEF DESCRIPTION OF DRAWINGS
