Surface ultrasonic scale prevention and removal system for solar photovoltaic panel

Abstract

The invention relates to a surface ultrasonic scale prevention and removal system for a solar photovoltaic panel. The system comprises the solar photovoltaic panel which is fixed on an inclined photovoltaic panel bracket. The system is characterized by further comprising an ultrasonic generator, an ultrasonic signal transmission cable and an ultrasonic energy converter, wherein the ultrasonic generator is used for generating ultrasonic waves along the surface of the solar photovoltaic panel; the ultrasonic signal transmission cable is used or transmitting ultrasonic signals generated by the ultrasonic generator to the ultrasonic energy converter; and the ultrasonic energy converter is used for converting the ultrasonic signals transmitted by the ultrasonic signal transmission cable into high-frequency mechanical shocks to be transmitted in dust accumulated on the solar photovoltaic panel. The surface ultrasonic scale prevention and removal system is simple in structure, convenient to install, low in manufacturing and use costs and long in service life, the all-day continuous working can be realized, and accumulation and scaling of dust can be inhibited in the earlier stage of the formation of dust; and mechanical action is applied to the accumulated dust scale, so that the accumulated dust scale can be loosened and peeled by virtue of natural wind.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic equipment, in particular to an ultrasonic anti-scaling and descaling system on the surface of a solar photovoltaic panel. Background technique [0002] With the depletion of primary energy, new energy has attracted more and more attention. As a new, clean and non-polluting energy, solar energy is developing rapidly. Solar photovoltaic power generation has the advantage of being able to convert into electrical energy only through one energy conversion. Therefore, solar photovoltaic power generation is widely constructed and utilized in my country, especially in the eastern and western regions. However, the wind, sand and dust pollution in the eastern and western regions of my country is relatively large, and dirt is easy to form on the surface of photovoltaic panels. These dust and dirt block the incident light, seriously affecting power generation efficiency and the service life of photo...

AI Technical Summary

Problems solved by technology

[0004] In summary, the above three methods for cleaning the dust on the surface of photovoltaic panels all have certain limitations.

At the same time, the cleaning frequency is restricted by seasons, water sources, personnel and technical maturity.

First: The method of water washing requires a large amount of water supply, and the continuous supply of water resources in areas with high light intensity is a big problem; Second: Water washing is greatly affected by the seasons, winter is cold, and the temperature is below zero. Too realistic; third: the disadvantage of using photovoltaic panel cleaning robots is that the cost of making guide grooves for photovoltaic panels in the early stage is high, the price of cleaning robots is high and the cost of maintenance and repairs in the later period is also high, and the acceptance of practical applications is limited; fourth: the above three technical methods are all It is to consider the cleaning of dust accumulation on the surface of photovoltaic panels, and does not consider how to prevent the formation of dust accumulation on the surface of photovoltaic panels
