Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, in particular to a photovoltaic cleaning robot suitable for the petrochemical industry. Background Technique

[0002] In the process of petrochemical production, many devices require a large amount of power supply. However, traditional energy supply methods often have problems such as high energy consumption and serious environmental pollution. Therefore, introducing a photovoltaic inverter can convert solar energy into electrical energy, providing clean and renewable energy for the petrochemical industry, reducing dependence on traditional energy, and reducing carbon emissions and environmental pollution.

[0003] The existing Chinese utility model patent with the reference publication number: CN220682518U discloses a photovoltaic cleaning robot suitable for cleaning photovoltaic modules. The photovoltaic cleaning robot includes a frame and walking wheels, guide wheels, and cleaning components arranged on the frame. The walking wheels are located on the upper surface of the photovoltaic module, the guide wheels are located on both sides of the photovoltaic module along its length direction, and the cleaning components clean the upper surface of the photovoltaic module; the length of the guide wheel along the direction perpendicular to the frame is greater than the thickness of the photovoltaic module. The guide wheel includes a cylindrical part and a conical part fixedly connected to the cylindrical part. The conical part is farther away from the frame relative to the cylindrical part, and the diameter of the conical part is smaller than the diameter of the cylindrical part. This photovoltaic cleaning robot improves the anti - detachment function, reduces the operation and maintenance costs solved by humans, and enhances the endurance ability.

[0004] Existing cleaning robots generally drive a brush to rotate through a motor to clean the photovoltaic panel, and adjust their own positions while cleaning to achieve the effect of cleaning the photovoltaic panel. Since the movement of the cleaning robot is synchronized with the rotation of the brush, this method will cause the brush to displace during rotation, resulting in a decrease in the relative friction force between the brush and the surface of the photovoltaic panel, affecting the cleaning effect. Moreover, existing cleaning robots may slip off the surface of the photovoltaic panel under the influence of wind during use. Content of the Utility Model
