[0002] Photovoltaic power stations are a sustainable energy development project that my country attaches great importance to. They convert light energy into electrical energy through electronic components such as crystalline silicon panels and generate electricity using solar energy. They are one of the important sources of electricity in my country. In the autumn and winter seasons, the existing photovoltaic power stations have frost on the surface of the solar panels due to the temperature difference between day and night, which reduces the power generation efficiency. Therefore, defrosting devices are needed to defrost the solar panels.

[0003] According to a Chinese patent with publication number CN214184485U, a defrosting device for a photovoltaic power station is disclosed. The beneficial effects achieved by the utility model are: the defrosting plate glued on the surface of the roller cleans the frost layer on the surface of the solar panel by continuous rotation, so that the frost layer is separated from the solar panel, and the inclined air pipe can blow and wash the surface of the solar panel.

[0004] In response to the above-mentioned disclosed patent content, the inventor believes that when the frost layer is cleaned to one side of the top of the solar panel by the defrost plate, one can only wait for the frost layer to melt automatically, but it is difficult to push the frost layer pushed to one side off the solar panel, causing the frost layer to accumulate on the solar panel for a long time, thereby reducing the defrosting effect of the solar panel.

[0013] A further improvement of the technical solution of the utility model is that a collecting groove is provided on the upper surface of one end of the assembly frame away from the defrost assembly, and the collecting groove penetrates to the outer wall of the assembly frame.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] Example 1

[0029] like Figure 1-5 As shown, the utility model provides a defrosting device for power station detection, including a photovoltaic panel 1, a support frame 2, a defrosting assembly 3 and an assembly frame 4, wherein the defrosting assembly 3 includes a heating defrosting roller 5 and an arc scraper 6 for defrosting the upper surface of the photovoltaic panel 1.

[0030] The inner wall of the heating and defrosting roller 5 is rotatably connected to a built-in shaft ring 12, and the inner wall of the built-in shaft ring 12 is movably connected to a central support tube 15, and the outer wall of the central support tube 15 is fixedly connected to a heating resistor net 13 for heating the heating and defrosting roller 5, and the outer wall of the heating resistor net 13 is fixedly connected to a heat-conducting ring 14 for accelerating heat conduction, and the heat-conducting ring 14 is made of metal with good thermal conductivity, which facilitates the rapid transfer of heat to the heating and defrosting roller 5. By utilizing the built-in shaft ring 12, the heating resistor net 13 will not rotate during the heating process, thereby affecting normal operation. At the same time, the heat-conducting ring 14 is utilized to facilitate the rapid transfer of heat from the heating resistor net 13 to the heating and defrosting roller 5, thereby facilitating subsequent defrosting work, and the rolling defrosting effect of the heating and defrosting roller 5 will not cause hard scratches on the surface of the photovoltaic panel 1.

[0031] Both ends of the central support tube 15 are fixedly connected with the lateral movable frame 7, and both sides of the assembly frame 4 are provided with lateral slide grooves 8 for the sliding connection of the lateral movable frame 7. One side of the lateral movable frame 7 is fixedly connected to one end of the arc scraper 6 through a connecting column. The bottom end of the arc scraper 6 is rotatably connected with the scraper 16, and the bottom surface of the scraper 16 is fixedly connected with rubber scraping teeth 18.

[0032] Example 2

[0033] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the bottom surface of the rubber scraper 18 is movably connected to the upper surface of the photovoltaic panel 1, and the upper surface of the scraper 16 is fixedly connected with an auxiliary spring 17, and the other end of the auxiliary spring 17 is fixedly connected to the bottom surface of the arc scraper 6. The elastic force of the auxiliary spring 17 on the scraper 16 enables the rubber scraper 18 to fit more closely with the surface of the photovoltaic panel 1, thereby ensuring the water scraping effect and further improving the cleaning effect.

[0034] The bottom end of the lateral movable frame 7 is slidably connected to the inner wall of the lateral sliding groove 8 through a sliding block, and the bottom end of the lateral movable frame 7 is threadedly connected to a threaded rod 11 through a threaded groove provided thereon.

[0035] Example 3

[0036] like Figure 1-5As shown, based on Example 1, the utility model provides a technical solution: preferably, one end of the threaded rod 11 is fixedly connected to an auxiliary gear 10, the outer wall of the auxiliary gear 10 is meshed with a power gear 9, and one end of the power gear 9 is fixedly connected to a driving motor.

[0037] A collecting groove is formed on the upper surface of one end of the assembly frame 4 away from the defrost assembly 3 , and the collecting groove penetrates to the outer wall of the assembly frame 4 .

[0038] The bottom surface of the assembly frame 4 is fixedly connected to the top of the support frame 2 , and the outer wall of the heating and defrosting roller 5 is movably connected to the upper surface of the photovoltaic panel 1 .

[0039] The following is a detailed description of the working principle of the defrost device used for power station inspection.

[0040] like Figure 1-5 As shown, when in use, the heating resistor net 13 is started to generate heat, and then the heat is transferred to the heating defrost roller 5 through the heat conductive ring 14. Since the heating resistor net 13 is evenly distributed on the outer wall of the central support tube 15, the heating defrost roller 5 can quickly and evenly melt the frost on the photovoltaic panel 1 without any residual problem.

[0041] Then, the driving motor is started to drive the power gear 9 to rotate, and the power gear 9 uses the auxiliary gear 10 to drive the threaded rod 11 to rotate, and the threaded rod 11 drives the side moving frame 7 and the central support tube 15 to move to the surface of the photovoltaic panel 1. During the movement, the heating defrost roller 5 will rotate around the central support tube 15 through the built-in shaft ring 12, and gradually melt the frost on the photovoltaic panel 1. During the movement, the side moving frame 7 will drive the arc scraper 6 to move, and use the rubber scraping teeth 18 at the bottom of the scraper 16 to scrape the melted water towards the collection tank until the frost on the photovoltaic panel 1 is completely eliminated.

[0042] The heat-conducting ring 14 is made of metal with good thermal conductivity, so as to facilitate the rapid transfer of heat to the heating and defrosting roller 5 .

[0043] During the rotation of the heating and defrosting roller 5, the central support tube 15 and the heating resistor network 13 are in a non-rotating state. The heating and defrosting roller 5 can be moved to the top of the collection tank opening driven by the side movable frame 7 without affecting the scraping and drainage work of the scraper 16.

[0044] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
