Description

Intelligent photovoltaic power generation panel cleaning system based on multi-level cleaning

Technical field

This utility model is in the field of photovoltaic panel cleaning, specifically an intelligent photovoltaic power generation panel cleaning system based on multi-level cleaning.

Background technique

At present, my country's photovoltaic modules are mostly cleaned by manual cleaning and high-pressure sprinkler truck flushing. Although it can effectively solve the problem of dust affecting photovoltaic power generation efficiency, the resulting high labor costs and water shortages restrict the development of enterprises. , at the same time, some experts and scholars have developed photovoltaic module cleaning robots, but they are not ideal in practical applications.

1. Manual cleaning: Since photovoltaic power plants in the west are generally built in deserts or Gobi deserts, the area is sparsely populated and lacks water resources. The disadvantages of manual cleaning are excessive labor costs, low cleaning efficiency, and poor light transmission of photovoltaic modules. rate and power generation efficiency have a certain impact.

2. Sprinkler truck cleaning: Some large-scale photovoltaic power stations use sprinkler truck flushing to clean photovoltaic modules. This method does not require a lot of manual participation, the cleaning speed is fast, and a large area of photovoltaic modules can be cleaned in a short time. However, The requirements for spacing between photovoltaic module arrays are relatively high, and a certain distance is required for the passage of sprinkler trucks. Moreover, the cost of sprinkler trucks is too high, and a large amount of water is required. Photovoltaic power stations in the northwest region inherently lack water resources. Therefore, it is not easy to clean with sprinkler trucks. Be applicable.

3. Photovoltaic module cleaning robot: At present, some companies have developed unattended photovoltaic module cleaning robots. This robot is placed at one end of each row of modules. It carries its own power supply and has a rotatable brush installed at the bottom. The upper and lower ends of the module As a cleaning robot walking track, scheduled automatic cleaning is realized through the main control. This cleaning method has been put into use in some power stations, but there are also some problems. For example, one robot needs to be placed for a row of components. The cost of the robot is too high, and a single cleaning machine is not available on the market. The price of the robot is about 10,000 yuan. According to the installation of 10 robots per megawatt, a 160-megawatt power station will require 1,600 robots. The initial investment is too large;

To this end, we propose an intelligent photovoltaic panel cleaning system based on multi-level cleaning.
