Vortex ring jet flow and negative pressure regulation and control method for crawling type photovoltaic cleaning robot

Abstract

The invention discloses a vortex ring jet flow and negative pressure regulation and control method for a crawling type photovoltaic cleaning robot. The method is characterized by comprising the steps:determining the lowest negative pressure value of each vortex ring jet-negative pressure adsorption system when a crawling type photovoltaic cleaning robot works normally according to the parametersof the crawling type photovoltaic cleaning robot and the inclination angle parameters of the photovoltaic array to be cleaned; determining a negative pressure set value of each vortex ring jet-negative pressure adsorption system when the crawling type photovoltaic cleaning robot normally works on the premise of keeping a certain safety margin; collecting an actual negative pressure value of each vortex ring jet-negative pressure adsorption system by utilizing an air pressure sensor, and carrying out fuzzy control and constant value control according to a difference value between a negative pressure set value of the vortex ring jet-negative pressure adsorption system and the actual negative pressure value of the vortex ring jet-negative pressure adsorption system; and on the basis that thecrawling type photovoltaic cleaning robot can reliably walk on a large-inclination-angle photovoltaic panel, the functions of strengthening cleaning and crossing the photovoltaic panel to move are achieved by adjusting the negative pressure set value of each vortex ring jet flow-negative pressure adsorption system, the power of an induced draft fan and the power of a dust suction fan.

Description

technical field [0001] The invention relates to the control field of an anhydrous cleaning device for photovoltaic panels, and relates to a vortex ring jet flow and negative pressure control method for a crawling photovoltaic cleaning robot. Background technique [0002] As a zero-pollution, zero-emission, renewable energy source, solar energy is an ideal energy source to solve the energy crisis. In view of the characteristics of photovoltaic power generation, large-scale photovoltaic power plants in my country are generally built in desert areas such as northeast or northwest, and these areas are often high dustfall areas. A large amount of dust deposited on the photovoltaic panel will reduce the radiant energy obtained by it and reduce the output power of the system. At the same time, the deposited dust will also change the thermal balance of photovoltaic panels, causing local heating, and in severe cases, a hot spot effect will be formed, threatening the safety of photov...

AI Technical Summary

Problems solved by technology

Existing literature query analysis shows that there is no relevant report on the control method of the negative pressure adsorption system of the photovoltaic cleaning robot using the principle of vortex ring jet flow, and the use of the walking mechanism plus negative pressure adsorption walking mode causes the cleaning robot to cross the photovoltaic panel. There is no proper solution to the problems of negative pressure failure and insufficient adsorption force
