Description

TECHNICAL FIELD

[0002] In recent years, photovoltaic power generation has developed rapidly at home and abroad, and in the near future, it will occupy an important position in world energy consumption, not only replacing part of conventional energy, but also becoming the main body of world energy supply. However, large-scale solar photovoltaic power stations are greatly affected by the natural environment. In winter, a large amount of snow will remain on the surface of the solar photovoltaic panel, not only causing damage to the photovoltaic panel assembly, but also blocking the surface of the solar photovoltaic panel, affecting the solar power generation efficiency. The existing common snow removal method is to set a snow removal device on the photovoltaic panel or on the photovoltaic panel mounting bracket, or to use a snow removal vehicle to remove the snow on the photovoltaic panel. The method of setting a snow removal device on the photovoltaic panel or on the photovoltaic panel mounting bracket requires setting a snow removal device on each photovoltaic panel. This structure is mostly used for photovoltaic panels installed on the roof or the top of the factory building, and the number of photovoltaic panels is generally small. Photovoltaic power plants have a large number of photovoltaic panels. Using this method to remove snow not only has a high cost, but also the snow removal device is only used after snowfall, and is idle at ordinary times, so the utilization rate of the snow removal device is low. Therefore, large-scale photovoltaic power plants generally use snow removal vehicles to remove snow.

[0003] The existing snow removal vehicles, such as the utility model patent with application number 202020226900.9, the utility model patent with application number 202221205223.8, and the utility model patent with application number 202220270393.8, respectively use a blowing mechanism to blow off the snow, a snow plate to scrape off the snow, and flexible bristles to sweep off the snow, to remove the snow on the photovoltaic panel. The snow removal method by blowing is only suitable for thin snow, and cannot be used for thick snow. The snow removal methods by scraping with a snow plate and by sweeping with flexible bristles both act on the working surface of the photovoltaic panel, which can easily damage the working surface of the photovoltaic panel.

[0004] In summary, there is a lack of a snow removal device in the prior art that is suitable for large-scale photovoltaic power plants, can be used to remove thick snow, and will not damage the working surface of the photovoltaic panel. SUMMARY

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

A snow removal method using the vehicle-mounted photovoltaic panel snow removal device according to any one of claims 3-7, comprising the following steps: S1: driving the vehicle body to one side of the starting position of a group of photovoltaic panels, adjusting the distance between the vehicle body and the photovoltaic panel group, so that the rotating radius of the telescopic arm arranged on the vehicle body is not less than the distance between the rotating shaft of the telescopic arm and the non-working surface of the photovoltaic panel, and then keeping the position of the vehicle body unchanged; S2: starting the constant pressure cylinder and the oil cylinder arranged on the vehicle body, driving the telescopic arm to rotate until the vibration snow removal mechanism at the front end of the telescopic arm is placed on the non-working surface of the photovoltaic panel, and then closing the oil cylinder so that the vibration snow removal mechanism only works under the action of the constant pressure cylinder; S3: keeping the distance between the vehicle body and the photovoltaic panel group unchanged, driving the vehicle body to move at a constant speed along the arrangement direction of the photovoltaic panel group, and starting the vibration snow removal mechanism to transmit excitation force to the photovoltaic panel to start snow removal; S4: when the vehicle body drives to the end position of the group of photovoltaic panels, the oil cylinder is started, and under the joint action of the oil cylinder and the constant pressure cylinder, the telescopic arm is pulled up to separate the vibration snow removal mechanism from the previous group of photovoltaic panels, and then the vehicle body continues to drive until the vehicle body drives to the starting position of another group of photovoltaic panels; S5: repeating S1 to S4 until all the snow on the photovoltaic panel group is removed, and then driving the vehicle body away from the area where the photovoltaic panel group is located to complete the snow removal work.
