Cleaning device for solar panel

Abstract

The invention discloses a cleaning device for a solar panel. The cleaning device is mounted on the solar panel; guide rails are arranged on the solar panel in the length direction; the cleaning devicecomprises a long water pipe slidingly connected with the guide rails, and a cover positioned on the surface of the solar panel; the long water pipe communicates with first nozzles and a second nozzle; one first nozzle is arranged between every two adjacent guide rails; the first nozzles extend into the cover, and are fixedly connected with the cover; the two sides of the cover are slidingly connected with two adjacent guide rails; the long water pipe is connected with a water outlet of a water pump; and a water inlet of the water pump is connected with a water tank. One part of water enters the cover by the first nozzles to form vertical eddy currents for spraying to the surface of the solar panel, and an ultrasonic cleaning device is combined to achieve a better cleaning effect; the other part of the water enters the guide rails by the second nozzle to clean and lubricate the guide rails; and through sliding connection between the long water pipe and the guide rails, the cleaning ofeach position of the solar panel can be realized.

Description

technical field [0001] The present invention relates to the field of cleaning technology, more specifically, it relates to a cleaning device for solar panels. Background technique [0002] With the rapid development of the world's production economy and the continuous increase of the global population, the non-renewable energy mainly based on fossil energy is decreasing day by day. At the same time, the ecological pollution caused by fossil energy has caused serious damage to the environment on which human beings depend. However, new energy sources based on solar energy have become one of the mainstream renewable energy sources, and are favored because of their universality, longevity, and huge total amount. Among them, photovoltaic power generation is a technology of solar energy application, which converts solar energy into electrical energy. Distributed photovoltaic power stations established by photovoltaic power generation technology have emerged as the times require an...

Problems solved by technology

However, dust, impurities and some corrosive substances in the air are very easy to adhere to the surface of the solar panel. Once it is washed by rain and the water stains are not wiped off, a large number of water marks will be formed, which will seriously affect the photoelectric conversion efficiency of the solar panel.

If leaves, bird droppings, floating soil and other highly adhesive debris cover the solar panels and do not clean them for a long time, problems such as lower conversion efficiency and shorter service life of solar panels will occur.

If the solar panels are installed at high altitude or the roof is high, and there is heavy snow cover, and cannot be cleaned in time, it may bring serious safety hazards

[0003] In the prior art, for the cleaning device of the distributed photovoltaic power station, one is to use cleaning equipment, such as the patent name: multi-functional solar panel cleaning vehicle, the patent application number is: 201410196364.1, the patent for the array of solar panels There are certain restrictions on design and installation. At the same time, one solar panel is installed with one cleaning device, which is costly, complicated to install, and occupies a large area; the other is to use a cleaning robot. For example, the patent name is: solar panel cleaning robot, Application number: 201610495980.6, this method can be used for automatic cleaning without modifying any photovoltaic modules, which saves labor costs, and can set different working modes, and the cleaning work can be completed with a small amount of water, which can save water resources, but the cost is too high. The maintenance cost is also high, it is easy to damage the surface of the solar panel, and it is difficult to clean the sloped roof

In addition, there is nano-film self-cleaning technology, which applies self-cleaning coatings to solar cell glass coatings, typically titanium dioxide coating materials, which are conducive to the cleaning of solar panels, but the biggest problems with this method are transparency and photocatalytic activity. Low performance indicators and high cost have not been widely used

At present, manual cleaning is still used more in my country, which is labor-intensive and low-efficiency.
