Windshield wiper type photovoltaic module cleaning device

Abstract

The invention relates to a windshield wiper type photovoltaic module cleaning device. The windshield wiper type photovoltaic module cleaning device comprises a moving device, a hanging arm device, a cleaning hanging bracket, a cleaning brush device and a position detection system; the moving device comprises four rolling wheels, a support frame and a rotating disc; the hanging arm device comprisesa main servo hydraulic oil cylinder and a hanging arm, and the main servo hydraulic oil cylinder is installed on the rotating disc; the back end of the hanging arm is hinged to the cleaning hanging bracket, the back portion of the hanging arm is provided with an auxiliary servo hydraulic oil cylinder, and the cleaning hanging bracket is connected with the cleaning brush device; the cleaning brushdevice comprises a cleaning brush unit, a length adjusting unit and a local powerful brushing unit; the local powerful brushing unit comprises a wedge-shaped brush block installed on the side of themiddle of a second brush plate, a powerful brushing driving motor and a rack; and the position detection system comprises a central control unit, a front infrared distance sensor, a back infrared distance sensor and a pressure sensor. The windshield wiper type photovoltaic module cleaning device has the characteristics of being simple in structure, convenient to adjust, efficient, intelligent andgood in cleaning effect, can adapt to cleaning of photovoltaic modules with different specifications and can remove stubborn stains.

Description

technical field [0001] The invention belongs to the field of photovoltaic module cleaning, and in particular relates to a wiper type photovoltaic module cleaning device. Background technique [0002] Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy; photovoltaic modules (commonly known as solar panels) are made of solar cells or by laser cutting machines or steel Solar cells of different specifications cut by a wire cutting machine are combined together to form a solar cell. Since the current and voltage of a single solar cell are very small, then we first connect them in series to obtain a high voltage, and then connect them in parallel to obtain a high current, and then output it through a diode (to prevent current return).

Problems solved by technology

[0003] Since photovoltaic modules need to be placed in an open-air environment, they are easy to be stained with dust or stains, affecting light transmittance, which is not conducive to absorbing solar power generation; due to large-scale photovoltaic power plants occupying a large area and a large number of components, manual cleaning is inefficient Poor; in the prior art, mechanical equipment is also used for cleaning. Common photovoltaic cleaning devices are usually fixed or rail-mounted, with complex structures, and it is difficult to adjust the angle, and the cleaning effect is not good; Foreign objects such as dirt, bird droppings, and sticky objects, if not properly cleaned, will eventually affect the power generation effect
