Double-roll-brush cleaning device for photovoltaic panels

Abstract

The invention provides a double-roll-brush cleaning device for photovoltaic panels. The cleaning device comprises a first main-roll-brush cleaning device and a second main-roll-brush cleaning device. The first main-roll-brush cleaning device is connected with the second main-roll-brush cleaning device through a connecting component. The first main-roll-brush cleaning device comprises a first subsidiary-roll-brush device, a second subsidiary-roll-brush device and a driving device. The first subsidiary-roll-brush device and the second subsidiary-roll-brush device are arranged in a parallel and staggered manner, wherein the first subsidiary-roll-brush device is located in front, and the second subsidiary-roll-brush device is located at the back. The driving device is located between the first subsidiary-roll-brush device and the second subsidiary-roll-brush device. The double-roll-brush cleaning device for the photovoltaic panels aims to achieve the effects that the device is simple in structure and convenient to disassemble and assemble; the two ends of the roll-brush device are stressed in a balanced manner; and cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the fields of solar power generation, power station operation and maintenance, and photovoltaic modules, in particular to a double-roller brush cleaning device for photovoltaic panels. Background technique [0002] In the practical application of solar photovoltaic power generation, photovoltaic modules are the most important unit of power generation, and their output power is directly affected by the intensity of sunlight. When sand, dust, and snow fall on the surface of photovoltaic modules, the light transmittance will be reduced, resulting in a significant decrease in photoelectric conversion efficiency. If the surface of solar photovoltaic panels is not cleaned, the accumulated dust will stay for a long time, thus blocking sunlight, which greatly reduces the efficiency of photovoltaic power generation. [0003] The photovoltaic panel roller brush cleaning device in the prior art is generally a single-roller brush structur...

AI Technical Summary

Problems solved by technology

[0003] The photovoltaic panel roller brush cleaning device in the prior art is generally a single-roller brush structure, which cannot thoroughly clean the long-term residual dust on the photovoltaic panel surface, and requires the cleaning device to perform multiple cleanings on the photovoltaic panel, which reduces the work efficiency. Moreover, the current motor is generally installed at one end of the overall device, which easily leads to the phenomenon that one end is heavy and the other end is light when the roller brush device is working, and the force on both ends is unbalanced and the foot is light, which may easily lead to the instability of the overall structure of the roller brush device.
