Description

Photovoltaic panel cleaning method
Technical Field
The invention relates to the technical field of photovoltaic panel cleaning, in particular to a photovoltaic panel cleaning method.
Background
With the gradual exhaustion of traditional fossil energy and the increasing concern of people on the problem of environmental pollution, solar photovoltaic power generation is increasingly applied as one of main green energy, and the scale of a solar power station reaches an unprecedented degree. However, in the actual operation process of the photovoltaic power station, because the photovoltaic power station is exposed outdoors for a long time, dust particles in the air are easy to accumulate on the surface of the photovoltaic panel to form accumulated dust, so that the power generation efficiency of the photovoltaic module is reduced, and huge economic loss is brought to photovoltaic power generation enterprises. Therefore, cleaning of the solar photovoltaic panel becomes an important issue for operation and maintenance of the photovoltaic power station.
Most of photovoltaic cleaning equipment in the current market adopts a fixed rail type to keep the equipment to stay on an inclined plane, and the equipment cannot be moved away, and the same equipment needs to be additionally arranged on each photovoltaic array, so that the cost is increased, and the defects are more; because the photovoltaic array is large in area and long in distance, the robot cannot clean the photovoltaic panel in time after being stained with dust; once the robot is transferred, the fixed track of the robot needs to be reinstalled; on the other hand, the cleaning robot does not collect dust, and can easily cause secondary pollution.
In order to solve the problems, for example, the patent document with the Chinese patent application number of 201921791080.1 and the publication number of 2020.06.12 discloses a solar photovoltaic panel cleaning robot, which comprises a walking mechanism and a climbing mechanism; the travelling mechanism comprises a rectangular frame, a roller brush support is respectively connected to the front frame and the rear frame of the rectangular frame, a roller brush and a roller brush driving device are arranged on the roller brush support, a dust suction nozzle is arranged on the inner side of the roller brush, and the dust suction nozzle is connected with a dust suction pump arranged on the rectangular frame; a transverse travelling wheel is fixedly arranged below the rectangular frame and is connected with a transverse travelling driving device; the gantry is fixedly arranged on the rectangular frame, the climbing mechanism is arranged below the gantry and on the inner side of the rectangular frame, the gantry is connected with the climbing mechanism through a lifting device, the climbing mechanism comprises a longitudinal traveling driving device, a longitudinal traveling wheel and a sucker, and the sucker is connected with a vacuum pump arranged on the rectangular frame. The cleaning robot can automatically clean dust on the surface of the photovoltaic panel, is flexible to move, high in working efficiency, and capable of being effectively applied to various photovoltaic power generation places, and is an intelligent photovoltaic panel cleaning device.
The structure of this document, it is only through the rotatory dust that cleans of roller brush in inhaling the dust storage bag through the dust absorption mouth, it does not do the collection to the dust that cleans, consequently, the size of dust absorption mouth just need adjust the dust that will clean that can be better according to the length of roller brush inhales, this has just also increased the size control degree of difficulty to the dust absorption mouth man-hour, and simultaneously, the dust of inhaling in the dust storage bag does not do further processing yet, consequently, the large granule dust in the dust storage bag still all exists same place for the tiny particle dust, thereby it often changes the clearance dust storage bag to lead to easily storing up the dirt bag like this and fill up easily, finally influence the cleaning efficiency of photovoltaic board.
