Movable cleaning photovoltaic module

Abstract

The invention provides a movable cleaning photovoltaic module. A photovoltaic module is included. Two sides of the lower portion of the photovoltaic module are connected with a roof through a telescopic device. The telescopic device is connected with a motor; the motor can drive the telescopic device to alternately stretch out and draw back to rotate the photovoltaic module; the two sides of an upper surface of the photovoltaic module are provided with sliding grooves respectively; a balancing weight is arranged in each sliding groove; the balancing weights are connected with the two ends of acleaning device respectively; the cleaning device comprises a water collector at an upper part and a cleaning cotton strip at a lower part, and the bottom of the cleaning cotton strip is just in contact with the top of the photovoltaic module; and when the photovoltaic module rotates, the balancing weight slides in each sliding groove due to the action of a gravity and drives the cleaning deviceto move to clean the upper surface of the photovoltaic module. According to the movable cleaning photovoltaic module, an angle can be adjusted according to an irradiation angle of sunlight, a utilization rate of solar energy is increased, meanwhile, the cleaning device can automatically move under the action of the gravity to clean the surface of the photovoltaic module while the angle is adjusted, the surface of the photovoltaic module is prevented from being polluted, and battery efficiency is improved.

Description

technical field [0001] The invention belongs to the field of photovoltaic equipment, in particular to a movable cleaning photovoltaic module. Background technique [0002] Photovoltaic modules are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy and send it to the battery for storage, or to promote the load to work. Photovoltaic modules are composed of solar cells or a combination of solar cells of different specifications cut by a laser cutting machine or a steel wire cutting machine. Since the current and voltage of a single solar cell are very small, 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. And they are packaged on a stainless steel, aluminum or other non-metal frame, the glass on the top and the back plate on the back are installe...

AI Technical Summary

Problems solved by technology

[0003] Ordinary photovoltaic modules are fixed, but the angle of sunlight is different in a day, the utilization rate of solar energy is not high enough for fixed photovoltaic modules, and the photovoltaic modules are exposed to the outside for a long time, and are susceptible to various pollution, such as bird droppings , dust and other dirt, if not cleaned in time, will further affect the battery efficiency
