Abstract

The invention relates to a dust extraction device for a photovoltaic cell panel based on an ultrasonic motor, and the dust extraction device belongs to the field of renewable energy sources. The dust extraction device comprises an external frame arranged around the photovoltaic cell panel, wherein the external frame is formed by connecting a pair of parallel guide rails to a pair of parallel frame connection rods; a sliding rod is arranged between the two guide rails; the ultrasonic motor connected with the first guide rail is arranged at one end of the sliding rod; a sliding block connected with the second guide rail is arranged at the other end of the sliding rod; and a cleaning brush is arranged on a rod body of the sliding rod. According to the dust extraction device, the cleaning brush is driven by the ultrasonic motor to move on the surface of the solar cell panel, so that dust falls from the surface of the solar cell panel; negative effects of the surface dust on the power supply capability of the solar cell panel are reduced; the dust extraction device is light and compact in structure; the power supply capability is improved; and the maintenance cost is lowered.

Description

technical field [0001] The invention relates to a dust removal device for a photovoltaic battery panel, belonging to the field of renewable energy. Background technique [0002] After the solar panel is used for a period of time, dust will accumulate on its photosensitive surface, reducing the power supply capacity of the solar panel. This problem is especially serious in places that lack rain and in space. Solar power plants in the desert usually have a large number of panels, and the workload and cost of manual dust removal are large; household solar panels are usually installed on the roof, which is inconvenient for manual dust removal; Technical issues to be resolved. [0003] Ultrasonic motor is a new type of actuator that uses the inverse piezoelectric effect of piezoelectric ceramics to excite ultrasonic vibrations and is driven by friction. Compared with traditional electromagnetic motors, ultrasonic motors have a large torque-to-mass ratio and a light and compact...
