Solar panel cleaning trolley with mechanical sweeping and electrostatic dust removing functions

Abstract

A solar panel cleaning trolley with mechanical sweeping and electrostatic dust removing functions is characterized in that four wheels are mounted on a box body; a cleaning and dust removing mechanismmounted in an outer box body is that a power wheel and a big belt pulley are coaxial; the big belt pulley is in transmission connection with a small belt pulley through a synchronous belt; a rollingbrush is mounted on a shaft of the small belt pulley; a gearwheel on a shaft of the big belt pulley drives a pinion in an engaging manner; two driving bevel gears are mounted on a shaft of the pinion,and each driving bevel gear drives a driven bevel gear in an engaging manner, and a disc brush is mounted on a shaft of each driven bevel gear. An electrostatic dust removing mechanism is that a cathode plate, a first filtering net, a second filtering net and an anode plate are sequentially mounted in the box body from bottom to top; the lower end of a hose communicates with the box body, and theupper end of the hose communicates with the outer box body through a flat sucker. The cleaning trolley has the advantages of being convenient to move, capable of mechanically sweeping and electrostatically removing dust, high in cleaning effect, free from secondary flying dust, low in energy consumption, and long in service life.

Description

technical field [0001] The invention belongs to a mechanical cleaning device for solar panels, in particular to a mobile solar panel cleaning vehicle with brush dust removal and electrostatic dust removal. Background technique [0002] In recent years, with the continuous expansion of the scale of photovoltaic power plants in my country, the cleaning problem of dust on the surface of solar panels has become increasingly prominent. According to NASA research, only 4.05 grams of dust per square meter will reduce the proportion of solar energy converted to electricity by up to 40%. At the same time, dust coverage will also cause problems such as local corrosion, reduced insulation and hot spot effect, which will bring the solar panel itself. Great adverse effects, so it is particularly important to regularly clean the surface of the solar panel. However, most of the photovoltaic power plants in my country are built in remote areas with harsh natural environments, where there a...

Problems solved by technology

According to NASA research, only 4.05 grams of dust per square meter will reduce the proportion of solar energy converted to electricity by up to 40%. Great adverse effects, so it is particularly important to clean the surface of solar panels regularly

However, most of my country's photovoltaic power stations are built in remote areas with relatively harsh natural environments, where there are many dusty weather, and they are far away from water sources, precipitation is scarce, and groundwater is scarce. Using conventional water washing will face the disadvantage of difficult water supply. Therefore, the development of high-efficiency and energy-saving dry cleaning equipment Can better deal with the cleaning problem of large-scale photovoltaic modules

[0003] According to the search, there have been technologies related to artificial dry cleaning devices. For example, the Chinese patent application number 201320103762.5 discloses "a photovoltaic module surface cleaning and sunshade integrated cleaning brush". The device is fixed with a cleaning shovel and dust removal Multi-layer dust removal mechanisms such as brushes and dust removal brushes consume a lot of energy and will cause great wear and tear on the surface of photovoltaic modules

Another example is "a dust removal device with a transparent thin-film solar cell" disclosed in Chinese Patent Application No. 201110279080.5. short life

[0004] The solar panel cleaning devices described in the above two patents are not suitable for cleaning large-scale photovoltaic modules
