They generally include transformers, inverters, photovoltaic arrays, and related auxiliary facilities. In daily use, photovoltaic panels of photovoltaic power stations need to be protected from wind, hail, and dust. Especially in hail weather, if hail hits the photovoltaic panels, it will damage the photovoltaic panels, so anti-hail devices will be used to protect them.

[0026] refer to Figure 1-6 , now an anti-hail device for photovoltaic panels of a photovoltaic power station provided by an embodiment of the utility model is described. An anti-hail device for photovoltaic panels of a photovoltaic power station comprises a support frame 1, a mounting plate 2 is fixedly connected to the upper end of the support frame 1, a photovoltaic panel 8 is fixedly connected to the upper end of the mounting plate 2, a protective frame 3 and a fixing component 4 are arranged on the upper end of the mounting plate 2, the mounting plate 2 is connected to the protective frame 3 through the fixing component 4, the photovoltaic panel 8 is located inside the protective frame 3, a protective plate 5 and a buffer component 6 are arranged inside the protective frame 3, the protective frame 3 is slidably connected to the protective plate 5, and the protective plate 5 is made of a transparent material.

[0027] Specifically, the protection frame 3 is fixed to the upper end of the mounting plate 2 by the fixing component 4. When encountering hail weather, hail falls on the protection frame 3 and the protection plate 5, which can prevent hail. At the same time, hail falls on the protection plate 5, which can also play a buffering role with the cooperation of the buffer component 6, and can protect the protection plate 5. When the photovoltaic panel 8 needs to be replaced, the fixing component 4 is used to release the fixing of the protection frame 3, so as to facilitate the removal of the protection frame 3 from the mounting plate 2, and then facilitate the replacement of the internal photovoltaic panel 8, thereby improving work efficiency.

[0028] The fixing assembly 4 includes a limit seat 401, an insertion rod 402, a telescopic rod 403, a first spring 404, a positioning plate 405 and a positioning hole 406. Both sides of the front end of the protective frame 3 are fixedly connected to the limit seat 401, and the inner sliding connection of the limit seat 401 is connected to the insertion rod 402, and the telescopic rod 403 is fixedly connected between the two insertion rods 402. The circumferential surface of the telescopic rod 403 is provided with a first spring 404, and the two ends of the first spring 404 are respectively fixedly connected to the insertion rod 402; the upper end of the mounting plate 2 is fixedly connected to the positioning plate 405, and the side end surface of the positioning plate 405 is provided with a positioning hole 406, the positioning hole 406 cooperates with the insertion rod 402, and the end of the insertion rod 402 close to the positioning hole 406 is provided with a downward inclined surface; the front end of the insertion rod 402 is fixedly connected to the auxiliary rod 9, and the auxiliary rod 9 is located at the end of the insertion rod 402 away from the positioning plate 405. During operation, the two insertion rods 402 are pulled toward each other by the auxiliary rod 9, so that the telescopic rod 403 contracts, thereby compressing the first spring 404, which helps to reset the insertion rod 402. As the insertion rods 402 move toward each other, the insertion rods 402 are separated from the positioning holes 406 of the positioning plate 405, thereby releasing the restriction on the protective frame 3, and then facilitating the removal of the protective frame 3 from the mounting plate 2, thereby improving work efficiency.

[0029] A square hole 10 is formed on the front face of the protection frame 3, and the positioning plate 405 is located inside the square hole 10 and is slidably connected to the square hole 10. The square hole 10 is provided to facilitate installation of the protection frame 3.

[0030] The upper end of the mounting plate 2 is fixedly connected to a limit frame 7, which is slidably connected to the protection frame 3, and the limit frame 7 is located inside the protection frame 3. By setting the limit frame 7, the installation of the protection frame 3 can be limited during operation, so that the protection frame 3 can be accurately fixed on the mounting plate 2.

[0031] The buffer assembly 6 includes a fixed plate 601, a second spring 602 and a limiting column 603. The inner wall of the protection frame 3 is fixedly connected with the fixed plate 601. The second spring 602 is arranged between the fixed plate 601 and the protection plate 5. One end of the second spring 602 is fixedly connected with the fixed plate 601, and the other end of the second spring 602 is fixedly connected with the protection plate 5. The side of the protection plate 5 close to the fixed plate 601 is fixedly connected with the limiting column 603, and the limiting column 603 is located inside the second spring 602. When working, when hail falls on the upper end of the protection plate 5, the protection plate 5 will be squeezed to slide inside the protection frame 3. With the cooperation of the fixed plate 601, the second spring 602 can be compressed, thereby playing a buffering role, protecting the protection plate 5, and helping to extend the service life of the protection plate 5; at the same time, with the cooperation of the limiting column 603, the second spring 602 can be prevented from deflecting during the compression process, so that the second spring 602 can work stably.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
