Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to an outdoor photovoltaic dust cleaning device. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It mainly consists of three parts: solar panels, controllers, and inverters. Solar panels, often simply called photovoltaic panels, accumulate dust on their outer surfaces under long-term outdoor use, affecting the solar energy absorption rate and reducing solar power generation efficiency. Therefore, regular cleaning or rinsing of the photovoltaic panel surface is necessary.

[0003] Currently, most photovoltaic (PV) modules are cleaned manually using tools such as rags and mops, which is time-consuming, labor-intensive, and inefficient. CN219124162U discloses a PV module dust cleaning device, in which multiple sprayers are arranged around the perimeter of the PV module, each sprayer connected to a water pump and an air pump, with the water pump housed in a water tank. Two track grooves are located on either side of the PV module, each track groove containing a slider, which is driven synchronously by a first motor. The cleaning components are fixed at both ends to the sliders in the two track grooves. However, this method requires configuring track grooves and corresponding sprayers on each PV module daily, necessitating modifications to the PV system. Large-scale modifications would be costly.
