Problems solved by technology

[0004] The purpose of the present invention is to provide a photovoltaic power station operation and maintenance device to solve the problem that most of the existing maintenance devices in the above background technology use scrapers or simple soft bristle structures to clean the photovoltaic panels. It needs to move back and forth on the photovoltaic panel, so when a single scraper or brush cleans the surface of the panel, it is easy to cause dust to leave a certain area of ​​the panel and then accumulate in other areas, which will lead to excessive accumulation of dust and affect the quality of the photovoltaic panels. The photoelectric conversion efficiency of the photovoltaic panel area where dust is accumulated, the actual maintenance and cleaning effect cannot meet the needs of use

Embodiment 1

[0036] In this embodiment, in order to solve the problem of low dust cleaning efficiency in the prior art, such as figure 1As shown, the operation and maintenance device includes a casing 1 and a cleaning brush 3. A solar module 2 is installed on the top of the casing 1. The cleaning brush 3 is installed on the horizontally distributed horizontal axis 4. The bottom end of the cleaning brush 3 and the upper end of the photovoltaic panel 5 The surfaces are in contact with each other, and the left end of the horizontal shaft 4 is connected to the vertical shaft 8 through the mutually meshing first bevel teeth 6 and the second bevel teeth 7, and the top end of the vertical shaft 8 is connected to the motor installed on the housing 1, and the vertical shaft is connected. The bottom end of 8 is connected to the roller 9 attached to the edge of the frame of the photovoltaic panel 5, and also includes a one-way bearing. Two second bevel teeth 7 are arranged symmetrically up and down, a...

Embodiment 2

[0041] In order to reduce the overall weight of the maintenance device and reduce the pressure on the photovoltaic panel 5 caused by unnecessary equipment, the difference between this embodiment and the first embodiment is that, such as Image 6 The shown suction device includes a fan blade 23. The fan blade 23 is rotated and installed on the side wall of the casing 1 through the fan shaft 22. The small diameter gear 21 installed on the fan shaft 22 meshes with the large diameter gear 21 on the right end of the horizontal shaft 4. , and the inner space where the fan blade 23 is located is communicated with the top end of the trachea 12. When the horizontal shaft 4 is in a rotating state, the horizontal shaft 4 will drive the fan shaft 22 and the fan blade 23 through two mutually meshing gears 21 to be able to synchronize relative to each other. The high-speed rotation causes the space on the right side of the fan blade 23 to generate a negative pressure effect, and the dust acc...

Abstract

A photovoltaic power station operation and maintenance device disclosed by the present invention comprises a shell and a cleaning brush, a solar assembly is installed at the top end of the shell, the cleaning brush is installed on a horizontally distributed transverse shaft, the top end of a vertical shaft is connected with a motor installed on the shell, and two second conical teeth are symmetrically arranged up and down. The edges of the two second conical teeth are engaged with the first conical teeth, and the two second conical teeth are rotationally installed on the vertical shaft through one one-way bearing. According to the operation and maintenance device for the photovoltaic power station, two groups of cleaning brushes rotate in different directions, so that surface dust is prevented from being sprung to other board areas in the maintenance process, the dust is gathered in the device, air pressure is generated by using rotating power to thoroughly discharge the dust, and meanwhile, the operation and maintenance device has the functions of hot spot detection and hot spot marking; the characteristic that the surface temperature of the hot spot is high is utilized to drive the memory alloy material to deform and generate driving force to complete marking of the position of the hot spot, and faster overhauling is achieved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power stations, in particular to an operation and maintenance device for photovoltaic power stations. Background technique [0002] The photovoltaic panels are arranged and used in large quantities in the area, and the method of collecting sunlight energy and converting it into electric energy is the photovoltaic power station in modern technology. More efficient use of solar energy, but because such areas often contain a lot of dust in the air, if regular maintenance is not carried out, the dust accumulation on the surface of the photovoltaic panel will greatly limit the photoelectric conversion performance. Therefore, in the prior art A maintenance device that moves on the photovoltaic panel will be used to clean the surface of the photovoltaic panel, but the existing similar maintenance devices have the following problems in actual use: [0003] Most of the existing maintenance devices of...
