[0002] A photovoltaic panel is a power generation device that generates direct current when exposed to sunlight. It converts solar energy into electrical energy with high photoelectric conversion efficiency. It is composed of solid photovoltaic cells made almost entirely of semiconductor materials. Photovoltaic panels are generally installed outdoors in an environment where they can be directly exposed to sunlight. When it snows in winter, snow will accumulate on the photovoltaic panels, which affects the use of the photovoltaic panels and increases the surface load. Snow removal equipment is usually used to remove the snow.

[0003] According to the Chinese patent application number: CN219697596U, a snow removal structure that can be used for photovoltaic panels includes a mounting frame, the inner side of the mounting frame is movably connected to a photovoltaic panel, sleeves are fixedly installed at both ends of the upper bottom end of the mounting frame, the outer side of the sleeve is movably connected to a spring, the bottom of the sleeve is fixedly connected to a connecting frame, and the lower end of the connecting frame is hinged to the lower end of the mounting frame. The utility model is provided with a sleeve, a spring, a connecting frame, etc. When there is too much snow on the surface of the photovoltaic panel, the weighted compression spring drives the sleeve to contract, so that the bottom surface of the photovoltaic panel contacts the trigger switch to turn on the heating coil to heat the photovoltaic panel, so that the snow on the top of the photovoltaic panel is melted by the heat, and then the large pieces of snow slide obliquely from the photovoltaic panel to achieve the effect of snow removal, which is less damage to the surface of the photovoltaic panel than the traditional brushing or scraping method of snow removal.

[0004] However, in the above scheme, the bottom of the photovoltaic panel is heated by a heating coil to melt the snow on the surface of the photovoltaic panel. However, there are still the following shortcomings: the surface of the photovoltaic panel cannot be heated directly, which makes the melting speed of the snow slow and the cleaning efficiency low. Utility Model Content

[0005] The purpose of the utility model is to provide a snow removal structure that can be used for photovoltaic panels, so as to solve the problem that the surface of the photovoltaic panel cannot be directly heated, resulting in a slow melting speed of the accumulated snow and a low cleaning efficiency.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a snow removal structure that can be used for photovoltaic panels, comprising two hot air blowers, the two hot air blowers are fixedly installed on both sides of the mounting frame, the photovoltaic panel is fixedly installed inside the mounting frame, an air duct is fixedly installed at the air outlet of the hot air blower, two blowing bins are fixedly installed on the top surface of the mounting frame, a connecting hole begins to be provided on one side of the blowing bin, the air duct is fixedly installed inside the connecting hole, a number of blowing outlets are provided on the other side of the blowing bin, and two sliding grooves are provided on the top surface of the mounting frame, a sliding rod is fixedly installed inside one of the two sliding grooves, and a scraper is slidably inserted into the outer wall of the sliding rod.

[0007] Preferably, a driving motor is fixedly installed inside another of the two sliding grooves, a threaded rod is fixedly installed at one end of the rotating shaft of the driving motor, a threaded hole is formed on one side of the scraper, and the threaded hole is threadedly connected to the outer wall of the threaded rod.

[0008] Preferably, a thermistor sensor is fixedly installed inside the blowing bin.

[0009] Preferably, a filter is fixedly installed at one end of the air supply pipe.

[0010] Preferably, a connecting plate is provided on the bottom surface of the mounting frame, a plurality of vibration motors are fixedly mounted on the top surface of the connecting plate, and the output ends of the vibration motors are fixedly mounted to the bottom surface of the mounting frame.

[0011] Preferably, a guide block is fixedly mounted on one side of the scraper.

[0012] Compared with the prior art, a snow removal structure for photovoltaic panels using the above technical solution has the following beneficial effects:

[0013] 1. When in use, it can directly heat the surface of the photovoltaic panel, so that the snow melts faster, making it difficult for the snow to remain on the surface for a long time, effectively preventing the snow from condensing into ice and being difficult to sweep away. At the same time, it can directly heat the snow, reduce energy consumption, avoid heating through heat conduction of other objects, increase heat utilization rate, and improve snow removal effect;

[0014] Second, through the drive motor, when the drive motor is started, it drives the scraper to move along the outer wall of the sliding rod, so as to scrape the snow on the surface of the photovoltaic panel. Through the thermistor sensor, the temperature inside the blowing chamber can be detected. When the temperature is too high, the hot air blower can be controlled to shut down or reduce the output to avoid overheating;

[0015] 3. The filter can filter the air entering the blowing chamber through the air duct to prevent dust from entering and keep the inside of the blowing chamber and the surface of the photovoltaic panel clean. The connecting plate can connect the mounting frame to the photovoltaic support frame. The vibration motor can drive the mounting frame to vibrate and accelerate the sliding rate of snow. The guide block can guide the scraped snow when the scraper is scraping the snow, so that part of the snow can be pushed out from both sides of the mounting frame to the top of the mounting frame, thereby reducing residual snow and improving the efficiency of snow removal.
