Abstract

The invention relates to a dust collection device, in particular to a photovoltaic panel surface dust collection device suitable for multiple forms of supports. The device comprises a long-strip brush mechanism crossing over the surface of a photovoltaic panel, and the long-strip brush mechanism is connected with a steel wire rope closed loop and comprises a long-strip brush rod and a steel wire rope pull rod, wherein the length of the long-strip brush rod is larger than the width of the photovoltaic panel. The steel wire rope closed loop comprises an extension rod, a tension pulley block and a turning pulley block, and each pulley block comprises a steel wire rope drive wheel. The photovoltaic panel surface dust collection device is easy to achieve, low in cost, small in power consumption, long in service life and suitable for multiple forms of supports and does not affect light ray receiving, and the dust collection span can be larger than 20 m.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a photovoltaic panel surface dust removal device suitable for supports in various forms. Background technique [0002] Because the earth's available energy is less and less, solar energy is an inexhaustible energy source. As a clean and pollution-free new energy source, solar energy has received widespread attention and use around the world in recent years, especially photovoltaics. generate electricity. [0003] However, solar photovoltaic panels will accumulate dust and gray spots when exposed to the atmosphere, which will reduce the solar conversion efficiency by 20%-40%. Partial coverage of photovoltaic panels by bird droppings and falling objects will cause spot thermal effects and damage photovoltaic panels. NASA and Boston University are researching self-cleaning technology developed for Mars missions for photovoltaic panel dust removal, which may not yet be commercialized due to ...
