Description

Technical Field

[0002] Solar photovoltaic power generation is a new type of green renewable resource that is widely used in production and life. However, outdoor dust, sand and other debris will pollute and cover the photovoltaic panels, affecting the power generation efficiency of photovoltaic modules. Severe local coverage will also lead to the "hot spot effect", which greatly affects the conversion efficiency of photovoltaic modules. Dust will have a negative impact on the performance of photovoltaic modules, and even local shadows on photovoltaic modules will cause a significant reduction in output power, so photovoltaic panels need to be cleaned regularly.

The solar photovoltaic panel cleaning device drives the driving gear to rotate by the motor. Since the outer edge of the driving gear is meshed with the driving rack, the driving gear drives the cleaning roller to move up and down when the driving gear rotates, and the surface of the photovoltaic panel is cleaned to prevent dust from accumulating on the surface of the photovoltaic panel, thereby ensuring the power generation efficiency of the photovoltaic panel. At the same time, when the cleaning roller moves up and down, the cleaning roller is driven to rotate by the motor, which further improves the cleaning effect.

[0004] However, the above-mentioned device needs to be fixedly installed in one position, and generally there are a large number of photovoltaic panels installed, so a large number of such photovoltaic panel cleaning devices need to be installed.

This may increase the overall investment cost of the photovoltaic system, affect the economic efficiency of the project, and the subsequent maintenance and repair costs are even greater. In view of the above problems, a photovoltaic power generation panel cleaning device is proposed to solve them. Utility Model Content

[0024] Specifically, the telescopic assembly 14 includes a first fixed plate 1401 and a second fixed plate 1402 , and second cleaning rollers 1403 are rotatably connected at both front and rear ends between the first fixed plate 1401 and the second fixed plate 1402 .

[0025] Specifically, a third motor 1404 is fixedly installed in the middle of the left side of the second fixed plate 1402, and the output end of the third motor 1404 passes through the second fixed plate 1402 and is fixedly connected to a threaded rod 1405.

[0026] Specifically, the surface of the threaded rod 1405 is threadedly connected to a threaded seat 1409, and the threaded seat 1409 is fixedly connected to the top plate inside the shell 1. The threaded seat 1409 is fixedly installed so that when the threaded rod 1405 rotates, the second cleaning roller 1403 is extended from the inside of the shell 1 through threaded cooperation.
