DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Specific examples are given below.

[0023] Please refer to Figure 1 - Figure 5 , the present invention provides a photovoltaic panel with hail protection and impact resistance, including a photovoltaic panel; the photovoltaic panel includes a protective housing 1; a battery cell 11 is fixedly connected to the bottom of the inner side wall of the protective housing 1; a reflective layer 12 is fixedly connected to the top of the battery cell 11; an EVA film layer 13 is fixedly connected to the top of the reflective layer 12; a surface glass 14 is fixedly connected to the top of the EVA film layer 13; a plurality of through holes 15 are opened on the top of the surface glass 14; the through holes 15 penetrate through the protective housing 1, the battery cell 11, the reflective layer 12 and the EVA film layer 13; a fixing tube 16 is fixedly connected to the inner side wall of the through hole 15; a spring 17 is fixedly connected to the inner side wall of the fixing tube 16; a support column 18 is fixedly connected to the end of the spring 17; a tempered glass protective cover 19 is fixedly connected to the end of the support column 18. During operation, in order to achieve energy conservation and reduction, China is vigorously developing clean energy. In the north of China, where the sunlight duration is long, photovoltaics can be vigorously developed. Electricity is generated through photovoltaic panels. The surface of the photovoltaic panel is the surface glass 14. When encountering hail weather, hailstones fall from a high altitude, with a large impact force and great destructiveness. If the hailstones hit the photovoltaic panel, it will cause irreparable damage to the photovoltaic panel. By opening the through holes 15 in the middle of the photovoltaic panel, a fixing tube 16 is installed in the through hole 15, and the support column 18 is supported by the spring 17 inside the fixing tube 16. By setting the tempered glass protective cover 19 on the top of the support column 18, the tempered glass protective cover 19 covers the surface of the photovoltaic panel, and the tempered glass protective cover 19 is made of a transparent material, so that light can directly pass through the tempered glass protective cover 19 and irradiate the surface of the photovoltaic panel. When encountering hail weather, the hailstones will directly hit the surface of the tempered glass protective cover 19, and the generated impact force will be transmitted to the support column 18, causing the support column 18 to move downward, thereby squeezing the spring 17. After being squeezed, the spring 17 will generate a reaction force for restoration, and then push the support column 18 back to its original position. Since force will be lost during transmission, the impact force is consumed in this process. By setting the tempered glass protective cover 19, the impact of hail on the photovoltaic panel is effectively reduced, and the situation of the photovoltaic panel being damaged by hail is effectively reduced, thereby reducing the impact of natural disasters on the equipment and reducing the loss of the equipment when encountering natural disasters.

[0024] Furthermore, asFigure 1 - Figure 3 As shown, a metal protection box 2 is fixedly connected to the side wall of the protection housing 1; a first magnet 21 is fixedly connected to the bottom of the inner side wall of the metal protection box 2; a second magnet 22 is fixedly connected to the end of the support column 18. During operation, when hailstones fall from a high altitude, their impact force is strong and the destructive power is large. As the hailstones continuously impact the tempered glass protection cover 19, the impact force will be transmitted to the support column 18 through the support column 18, thereby compressing the spring 17. By arranging the second magnet 22 and the first magnet 21 at the bottom of the support column 18, and the two poles of the first magnet 21 and the first magnet 21 are opposite to each other, that is, there is a repulsive force between the first magnet 21 and the second magnet 22. When the impact force of the hailstones is transmitted to the second magnet 22, the second magnet 22 will approach the first magnet 21, and under the action of the repulsive force, the second magnet 22 will be pushed back to its original position. By transmitting the impact force of the hailstones twice, a large amount of impact force can be consumed, thereby achieving the effect of using softness to overcome hardness and reducing the impact of hailstones on the equipment.

[0025] Furthermore, as Figure 2 and Figure 3 shown, a sponge plate 3 is provided at the bottom of the second magnet 22; the sponge plate 3 is fixedly connected to the bottom of the second magnet 22. During operation, after the tempered glass protection cover 19 is continuously impacted by hailstones, the impact force will be transmitted to the second magnet 22, causing the second magnet 22 to approach the first magnet 21. By arranging the sponge plate 3, the first magnet 21 and the second magnet 22 are effectively separated, thereby reducing the situation where the first magnet 21 and the second magnet 22 come into contact with each other and are damaged, and effectively increasing the service life of the equipment.

[0026] Furthermore, as Figure 1 - Figure 3 shown, a transparent protective film 4 is provided on the top of the tempered glass protection cover 19; the transparent protective film 4 is fixedly connected to the top of the tempered glass protection cover 19. During operation, by arranging the transparent protective film 4 on the top of the tempered glass protection cover 19, when encountering smaller hailstones, the hailstones will impact on the surface of the transparent protective film 4, and the transparent protective film 4 itself is a consumable. When the transparent protective film 4 is broken, the staff can replace the transparent protective film 4, so that the small hailstones cannot damage the tempered glass protection cover 19, thereby effectively increasing the service life of the tempered glass protection cover 19 and reducing the cost of replacing the tempered glass protection cover 19. By arranging the transparent protective film 4, the transparent protective film 4 can resist smaller hailstones, and when encountering larger hailstones that the transparent protective film 4 can no longer resist, it can also provide a certain degree of resistance and reduce the pressure on the tempered glass protection cover 19.

[0027] Furthermore, as Figure 2 、 Figure 3 and Figure 5As shown, a hydrogel film 5 is provided on the top of the surface glass 14; the hydrogel film 5 is fixedly connected to the top of the surface glass 14. During operation, after the transparent protective film 4 and the tempered glass protective cover 19 are broken by hail, the hydrogel film 5 provided on the white surface of the surface glass 14 can effectively protect the photovoltaic panel to a certain extent. At the same time, the hydrogel film 5 has a certain flexibility, which can effectively reduce the situation that the broken tempered glass protective cover 19 scratches the surface glass 14. Moreover, the hydrogel film 5 is attached to the surface of the surface glass 14, which is convenient for the staff to replace the hydrogel film 5.

[0028] Working principle: In order to achieve energy conservation and reduction, China is vigorously developing clean energy. In the northern part of China, where the sunlight duration is long, photovoltaics can be vigorously developed to generate electricity through photovoltaic panels. The surface of the photovoltaic panel is surface glass 14. When hail weather occurs, hail falls from a high altitude with a large impact force and great destructiveness. If the hail hits the photovoltaic panel, it will cause irreparable damage to the photovoltaic panel. By opening through holes 15 in the middle of the photovoltaic panel, fixing tubes 16 are installed in the through holes 15. Support columns 18 are supported inside the fixing tubes 16 by springs 17. A tempered glass protective cover 19 is provided at the top of the support column 18, and the tempered glass protective cover 19 covers the surface of the photovoltaic panel. The tempered glass protective cover 19 is made of a transparent material, and light can directly pass through the tempered glass protective cover 19 and irradiate onto the surface of the photovoltaic panel. When hail weather occurs, the hail will directly hit the surface of the tempered glass protective cover 19, and the generated impact force will be transmitted to the support column 18, causing the support column 18 to move downward, thereby squeezing the spring 17. After being squeezed, the spring 17 will generate a reaction force for restoration, and then push the support column 18 back to its original position. Since force will be lost during transmission, the impact force is consumed in this process. By setting the tempered glass protective cover 19, the impact of hail on the photovoltaic panel is effectively reduced, and the situation where the photovoltaic panel is damaged by hail is effectively reduced, thereby reducing the impact of natural disasters on the equipment and reducing the loss of the equipment when encountering natural disasters. When hailing, since the hail falls from a high altitude with a strong impact force and great destructiveness, as the hail continuously hits the tempered glass protective cover 19, the impact force will be transmitted to the support column 18 through the support column 18, and then compress the spring 17. By providing a second magnet 22 and a first magnet 21 at the bottom of the support column 18, and the first magnet 21 and the first magnet 21 have the same poles facing each other, that is, there is a repulsive force between the first magnet 21 and the second magnet 22. When the impact force of the hail is transmitted to the second magnet 22, the second magnet 22 will be close to the first magnet 21, and under the action of the repulsive force, the second magnet 22 will be pushed back to its original position. By transmitting the impact force of the hail twice, a large amount of impact force can be consumed, thereby achieving the effect of using softness to overcome hardness and reducing the impact of hail on the equipment. After the tempered glass protective cover 19 is continuously impacted by hail, the impact force will be transmitted to the second magnet 22, causing the second magnet 22 to be close to the first magnet 21. By providing a sponge plate 3, the first magnet 21 and the second magnet 22 are effectively separated, thereby reducing the situation where the first magnet 21 and the second magnet 22 come into contact with each other and are damaged, and effectively increasing the service life of the equipment. By providing a transparent protective film 4 at the top of the tempered glass protective cover 19, when encountering smaller hail, the hail will hit the surface of the transparent protective film 4, and the transparent protective film 4 itself is a consumable. When the transparent protective film 4 is broken, the staff can replace the transparent protective film 4 so that small hail cannot damage the tempered glass protective cover 19.Furthermore, the service life of the tempered glass protective cover 19 is effectively increased, and the cost of replacing the tempered glass protective cover 19 is reduced. By providing the transparent protective film 4, the transparent protective film 4 can resist small hailstones. When encountering larger hailstones that the transparent protective film 4 can no longer resist, it can still provide a certain degree of resistance, reducing the pressure on the tempered glass protective cover 19. After the transparent protective film 4 and the tempered glass protective cover 19 are broken by hailstones, the hydrogel film 5 applied to the white surface of the surface glass 14 can effectively protect the photovoltaic panel to a certain extent. At the same time, the hydrogel film 5 has a certain degree of flexibility, which can effectively reduce the situation where the broken tempered glass protective cover 19 scratches the surface glass 14. Moreover, the hydrogel film 5 is attached to the surface of the surface glass 14, which facilitates the staff to replace the hydrogel film 5.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
