Photovoltaic module cleaning device and cleaning method thereof

Abstract

The invention discloses a photovoltaic module cleaning device which comprises a traveling mechanism and a cleaning mechanism. The traveling mechanism comprises a main body framework, a transverse power assembly and a longitudinal power assembly; the main body framework is limited on an upper frame and a lower frame of a photovoltaic module through an upper positioning wheel set and a lower positioning wheel set, the transverse power assembly comprises a transverse motor, a transmission shaft connected with the transverse motor, driving wheels and driven wheels, the driving wheels and the driven wheels are arranged on the transmission shaft, the longitudinal power assembly comprises a longitudinal motor, a double-groove rope-winding wheel connected with the longitudinal motor, a tensioning device, a fixed pulley and a tow rope, the tow rope is connected with the bottom end of a cleaning mechanism, the tow rope is arranged on the double-groove rope-winding wheel in a winding mode after the direction of the tow rope is changed by the fixed pulley, and the tow rope comes out of the double-groove rope-winding wheel in a winding mode to be connected with the top end of the cleaning mechanism; the outer wall of the cleaning mechanism is in contact connection with the inner wall of the main body framework through universal balls and is support on the main body framework reversely through rolling wheels. According to the photovoltaic module cleaning device, the traveling mechanism can drive the cleaning mechanism to walk transversely and longitudinally, and the cleaning mechanism can conduct sectional type cleaning on the photovoltaic module.

Description

technical field [0001] The invention belongs to the field of photovoltaic power plants, in particular to a cleaning device and a cleaning method for cleaning photovoltaic modules. Background technique [0002] With the development of the photovoltaic industry, the installed capacity of solar power plants around the world is constantly increasing. How to improve the power generation efficiency of photovoltaic power plants under the condition of the same installed capacity is particularly important. Since solar panels are generally installed on roofs or even in desert areas, there is a lot of dust and dirt, and the accumulation of dust and dirt on the solar panels will block the sunlight, resulting in a decrease in the power generation efficiency of the solar panels. Therefore, if the solar panel can be effectively cleaned, the power generation efficiency of the photovoltaic power station can be further improved under the same installed capacity. [0003] At present, the equ...

Problems solved by technology

A large amount of water is required for cleaning, so it is not suitable for water-scarce areas in the west

However, if water cleaning is not used, the dust raised by the roller brush during cleaning is difficult to deal with, and the dust will fall on the modules again, causing secondary pollution and greatly reducing the cleaning efficiency. The traditional roller brush is not clean when cleaning, and it is difficult to walk, which will cause damage to the entire equipment

The traditional traveling mechanism adopts the method of rack and pinion or synchronous wheel and synchronous belt, which is not only expensive but also needs regular maintenance, which is difficult to apply to the harsh outdoor working environment
