Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a photovoltaic module surface cleaning device and a use method thereof. Background Art

[0002] In the application of solar energy, the power generation of photovoltaic modules depends on many factors. In addition to the influence of electrical components such as inverters and transformers, in snowy weather in winter, a large amount of snow will remain on the surface of photovoltaic modules, which will not only cause damage to the photovoltaic panel components, but also block the surface of the solar photovoltaic panels, affecting the efficiency of solar power generation.

[0003] The existing snow removal method uses a snowplow to directly shovel snow on the surface of the photovoltaic module. However, during the snowplow process, the snowplow directly contacts the photovoltaic module, which is easy to damage it. At the same time, some snow accumulates on the surface of the photovoltaic module for a long time and is easy to freeze. It is not suitable to clean the ice at this time. In addition, when shoveling snow, a small amount of snow is likely to remain on the surface, which makes it easy to clean incompletely. For this reason, we propose a photovoltaic module surface cleaning device and a method for use. Summary of the invention

[0018] Compared with the prior art, the advantages and positive effects of the present invention are: 1. The present invention proposes a photovoltaic module surface cleaning device and a method of using the device, which drives a sliding frame to slide through an electric slide rail, so that a first gear on the surface of a support rod contacts a first rack on the slide rail. At this time, the moving first gear drives a push rod on the surface to rotate through the support rod, and the push rod drives a rotating cylinder to rotate. At this time, the snow shovel at the bottom rotates, and at the same time, the sliding frame drives the cleaning frame to move through the rotating cylinder, so that the snow shovel on the surface of the cleaning frame can rotate while moving. The snow shovel is tilted to improve the efficiency of snow removal. At the same time, the snow shovel is at a distance from the photovoltaic module, and the snow shovel does not directly contact the photovoltaic module body, which can reduce the extra burden caused by friction and resistance, making the snow shoveling process easier, thereby improving work efficiency and avoiding damage to the surface of the photovoltaic module caused by the snow shovel when it contacts the photovoltaic module.

[0019] 2. The present invention proposes a photovoltaic module surface cleaning device and a method of using the device, which can start a fan during cleaning to suck the raised snow into the interior of a rotating drum. At the same time, a convex lens is provided on the surface of the rotating drum, which can focus external light and heat the internal heat-conducting rod. The convex lens rotates with the rotating drum, which can absorb the surrounding light more efficiently and focus it on the heat-conducting rod to speed up its heating speed. At this time, the accumulated snow can be heated and melted, and the melted snow water enters the connecting pipe and the water collecting box. During rotation, the heated snow water is thrown out by centrifugal force and contacts with the remaining thin snow on the top of the photovoltaic module body to melt it. In addition, by spraying water, snow and dust can be removed from some dead corners that are difficult to clean.

[0020] 3. The present invention proposes a photovoltaic module surface cleaning device and a method of using the device, which contacts the first guide groove through a guide rod, and when the fourth gear on the positioning column contacts the second, the fourth gear drives the positioning column to rotate half a circle, and the rotating frame drives the second gear to rotate half a circle. At the same time, the rotating frame drives the second gear to move upward and contact with the second gear ring, and the second gear ring can be used to drive the connecting tube to rotate, and the connecting tube drives the third gear on the surface of the cleaning frame to rotate half a circle through the first gear ring, and drives the soft plate on the surface of the cleaning frame to rotate half a circle. At this time, the soft plate is perpendicular to the photovoltaic module and contacts the surface of the photovoltaic module. In conjunction with the snow water sprayed from the water collection box, the melted snow water and less accumulated snow on the surface can be cleaned, which effectively improves the snow removal efficiency, and can timely clean the snow water on the surface to avoid the snow water freezing for too long, thereby improving the working effect of the device.

[0021] 4. The present invention proposes a photovoltaic module surface cleaning device and a method of use, which drives the soft plate at the bottom to rotate through a rotating cylinder. During the process of the soft plate cleaning the snow, water and dust on the surface of the photovoltaic module, the fan drives the air flow to the inside of the water collecting box through the connecting pipe, and the air inside the rotating cylinder can be heated by the heating of the heat conductive rod. At this time, the surface of the surrounding photovoltaic module body can be blown, which can effectively speed up the cleaning efficiency of dust and snow water, so that the surface of the photovoltaic module body can be quickly dried.

9. The photovoltaic module surface cleaning device according to claim 5, characterized in that: A plurality of sliding grooves are provided on the surface of the support frame (2).

10. A method for cleaning the surface of a photovoltaic module, applied to a photovoltaic module surface cleaning device and method of use as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1: When processing snow, the electric slide rail (4) drives the slide frame (5) to slide, and the push rod (16) drives the rotating cylinder (8) to rotate. At this time, the snow shovel (11) at the bottom of the rotating cylinder (8) rotates while moving, and the surface of the photovoltaic module body (3) is cleared of snow; S2: When processing thin snow, the fan (31) is started to suck the lifted snow into the interior of the rotating cylinder (8), the convex lens (30) focuses the external light, and the snow is heated and melted by the heat conducting rod (32), and the melted snow water is thrown out by centrifugal force and contacts the thin snow remaining on the top of the photovoltaic module body (3), thereby melting it; S3: When handling thin snow, the soft plate (21) is rotated so that the soft plate (21) is perpendicular to the photovoltaic module body (3) and in contact with the surface of the photovoltaic module, and the snow water sprayed from the water collection box (34) is used to clean the melted snow water and the small amount of snow on the surface of the photovoltaic module body (3); S4: After the accumulated snow is processed, the fan (31) drives the airflow to blow air to the surface of the surrounding photovoltaic module body (3), thereby accelerating the cleaning efficiency of dust and snow water.
