Photovoltaic panel frame with cleaning and protecting functions

Abstract

The invention discloses a photovoltaic panel frame with cleaning and protecting functions. The photovoltaic panel frame comprises a base plate, a bracket, a mounting panel and a photovoltaic panel. The photovoltaic panel frame is characterized in that a cleaning assembly is rotatably mounted on the mounting panel and comprises a mounting block, a first pipeline is fixedly connected to the end surface of the mounting block, a water pump is mounted on the base plate, a water outlet of the water pump is connected with one end of the first pipeline, and a first valve is arranged at the joint of the water outlet and the first pipeline; a plurality mounting grooves are formed in the mounting block, worm wheels are mounted in the mounting groove, and nozzles are radially and fixedly connected to the side walls of the worm wheels; worm rods matched with the worm wheels are rotatably mounted on the mounting block and coaxially connected with a second electric motor mounted on the mounting block; and the photovoltaic panel frame further comprises a hose, one end of the hose is communicated with inner cavities of the nozzles, and the other end of the hose is communicated with an inner cavity of the first pipeline. According to the photovoltaic panel frame with the cleaning protecting function, the photovoltaic panel can be cleaned completely with no dead angle, accumulated dust, impurities, accumulated snow and ice on the photovoltaic panel can be effectively cleaned, and the photovoltaic panel can be protected under bad weather environments.

[0002] Photovoltaic power generation system is a power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. Its main components are photovoltaic modules, batteries, controllers and inverters. It is characterized by high reliability, long service life, no pollution to the environment, and energy Independent power generation and grid-connected operation are favored by enterprises and organizations in various countries, and are widely used in the field of clean energy. For photovoltaic modules that have been used for a long time, dust accumulation on the surface of photovoltaic panels is very common. After dust accumulation on photovoltaic panels, the power generation efficiency decreases, and timely At present, the main method of cleaning is manual cleaning. Manual cleaning takes a long time, is expensive, and has low efficiency. Especially for ground photovoltaic power stations, if manual cleaning is performed, the manpower invested will be too large. The efficiency is obviously reduced, and water needs to be sprayed to cool down. In winter, snow will cover the surface of the photovoltaic panel, which is difficult to clean. At present, the main method is to build a sprinkler device near the photovoltaic module. Waste of resources, the accumulated water remaining on the photovoltaic panel components in cold conditions will freeze and affect the normal use of photovoltaic panels
