Dust removal device for solar panel

Abstract

The invention provides a dust removal device for a solar panel. The dust removal device comprises a first rail and a second rail, a worm, an ultrasonic vibration device, a brush, a fan and an ultrasonic sensor, wherein the first rail and the second rail are configured to be arranged on two sides of the solar panel; the worm is connected with the first rail and the second rail; the ultrasonic vibration device is fixed on a stepping motor on a frame capable of moving along the worm to swing bilaterally; the brush is fixed on the frame, and configured to move in the direction of the worm througha second driving mechanism and clean the solar panel; the fan is fixed on the frame capable of moving along the worm and blows away dust brushed by the brush; and the ultrasonic sensor is configured to detect the distance between the frame and the first rail or the second rail, and enables the frame to return to the first rail or the second rail when the distance is lower than a preset threshold.The dust removal device cleans the dust on the solar panel by the brush after ultrasonic vibration, and finally blows away the dust brushed by the brush by the fan.

Description

technical field [0001] The present invention relates to the field of machinery, in particular, to a dust removal device for solar panels. Background technique [0002] At present, in China, the dust on the solar panel has an important impact on solar power generation. Take the 180-watt solar panel as an example. After testing, when the dust coverage on the surface of the solar panel reaches 4.05 grams per square meter, the power generation will drop by about 40%, which is equivalent to a 72 watt drop in power generation, that is, the actual usable power is only 108 watts, which is much lower than the installed power. 180 watt panels behind this unit. [0003] There are two traditional methods of dust removal on the surface of solar panels: one is to use water washing, which will consume a lot of manpower and water resources, and this method can only be applied to solar panels installed in low positions, such as solar lawn lights , solar floor lamps, etc., for solar panels ...

Problems solved by technology

[0003] There are two traditional methods of dust removal on the surface of solar panels: one is to use water washing, which will consume a lot of manpower and water resources, and this method can only be applied to solar panels installed in low positions, such as solar lawn lights , solar floor lamps, etc., for solar panels installed in higher positions, such as solar street lights and roof solar power supply devices, it is extremely inconvenient to remove dust; the other is to remove dust from the surface of solar panels through pneumatic dust removal, and the structure of such devices is complex. Poor reliability, improper operation will damage the solar panels, and the initial investment and later maintenance costs are high, which greatly increases the cost of power generation and is not easy to popularize and apply

[0004] It can be seen that the current dust removal device requires a lot of water resources and manpower. Generally, solar panels are installed in arid areas and high mountain areas. It is difficult to obtain water and the cost is high.

In addition, due to the limited bearing capacity of solar panels, the current dust removal device is too heavy, which will damage the solar panels when they are working.

In addition, the current dust removal device does not consider the problem of sand prevention, it will not work after a period of time, and the reliability is poor

When the dust removal robot finishes cleaning one set of solar panels, it is inconvenient to move, which is not conducive to cleaning another set of solar panels
