[0002] With the rise of energy prices, the development and utilization of new energy has become the main research topic in the energy field today. Since solar energy has the advantages of no pollution, no regional restrictions, and inexhaustible, the study of solar power generation has become the main direction of the development and utilization of new energy. Using solar cells to generate electricity is a major way for people to use solar energy today.

[0003] Currently, when photovoltaics are installed on the roofs of industrial and commercial factories, the mounting structure of the solar photovoltaic device is fixed to the roof, and then the photovoltaic panel is clamped at a certain angle through the mounting structure of the solar photovoltaic device to complete the installation of the solar photovoltaic device.

Due to the capillary phenomenon between the clip-on components, water from the outside of the mounting structure seeps into the inside of the mounting structure through capillary phenomenon, which in turn causes water accumulation inside the mounting structure, affecting the working performance of the photovoltaic panel and even causing internal circuit short circuit.

[0048] Referring to Figures 1 to 3, Figure 1 shows a cross-sectional view of the structure of the solar photovoltaic device installation structure 100 in one embodiment of the present application. Specifically, it can be understood that the solar photovoltaic device installation structure 100 is in the shape of a long strip, arranged on one side of the photovoltaic panel 210, and is used to clamp the edge of the photovoltaic panel 210 on that side. The solar photovoltaic device is obtained by assembling a plurality of photovoltaic panels 210 and the solar photovoltaic device installation structure 100, wherein the solar photovoltaic device installation structure 100 can be between two photovoltaic panels 210, or at the edge of the entire solar photovoltaic device, such as the edge of any side of the four sides of the rectangle, as shown in Figure 3. The solar photovoltaic device installation structure 100 provided in one embodiment of the present application includes: a support 110, a first support assembly 120, a second support assembly 130, a clamping assembly 140, and a cover plate 150.

[0049] Referring to FIG. 1 , in the above-mentioned solar photovoltaic device installation structure 100, the support 110 includes a bottom plate 111 and a bracket member 112, and the bracket member 112 is connected to the bottom plate 111. The first support assembly 120 is connected to the bottom plate 111. The second support assembly 130 is connected to the bracket member 112 and is located on the side of the first support assembly 120 away from the support 110. One end of the clamping assembly 140 is clamped with the first support assembly 120, and the other end is clamped with the second support assembly 130. The clamping assembly 140 is used to clamp the photovoltaic panel 210, and a cavity 141 is provided on the side of the clamping assembly 140 away from the second support assembly 130. The cover plate 150 is covered on the side of the clamping assembly 140 away from the second support assembly 130 and covers the cavity 141.

[0050] During the actual installation process of the above-mentioned solar photovoltaic device installation structure 100, the base plate 111 is set at the location to be installed, such as a roof or a mountain. Since one end of the clamping assembly 140 is clamped with the first support assembly 120 and the other end is clamped with the second support assembly 130, and the cover plate 150 is set on the side of the clamping assembly 140 away from the second support assembly 130, a cylindrical cavity is formed between the cover plate 150, the first support assembly 120, the second support assembly 130 and the base. The cover plate 150 is set on the side of the clamping assembly 140 away from the second support assembly 130 and covers the cavity 141, so that when liquids such as rainwater seep into the cylindrical cavity formed between the cover plate 150, the first support assembly 120, the second support assembly 130 and the base through the gap between the cover plate 150 and the clamping assembly 140, due to the cavity 141, 1 and the cover plate 150 have a relatively large gap, so rainwater and other liquids will enter the space between the cavity 141 and the cover plate 150, and because the mounting structure 100 of the solar photovoltaic device is in the shape of a long strip, the space between the cavity 141 and the cover plate 150 is in the shape of a long strip parallel to the mounting structure 100 of the solar photovoltaic device and has openings at both ends, so the liquid entering the space between the cavity 141 and the cover plate 150 will be discharged from the openings on both sides, thereby preventing the liquid from entering the cover plate 150, the first support assembly 120, the second support assembly 130 and the base to form a cylindrical cavity due to capillary phenomenon, thereby affecting the working performance of the photovoltaic panel 210 and even causing an internal circuit short circuit.

The two first support legs 121 are respectively located on both sides of the support member 112, and the distance between the two first support legs 121 gradually expands in the direction away from the bottom plate 111. The two second support legs 131 are respectively located on both sides of the support member 112, and the distance between the two second support legs 131 gradually expands in the direction away from the bottom plate 111. The two clamping members 142 are respectively located on both sides of the support member 112, one end of the clamping member 142 is clamped with the first support leg 121, and the other end is clamped with the second support leg 131. The clamping member 142 is used to clamp the photovoltaic panel 210, and a cavity 141 is provided on one side of the clamping member 142 away from the second support leg 131.

[0052] Referring to Figure 1, in this embodiment, the distance between the two second supporting legs 131 gradually expands in the direction away from the bottom plate 111, and the distance between the two first supporting legs 121 gradually expands in the direction away from the bottom plate 111, so that the first supporting leg 121 and the second supporting leg 131 inclined to the same side of the bracket member 112 can clamp a clamping member 142, and the clamping member 142 will not be interfered with by the bracket member 112. The two clamping members 142 are respectively located on both sides of the bracket member 112, and the two clamping members 142 are respectively clamped by the second supporting legs 131 and the first supporting legs 121 located on both sides of the bracket member 112, so that a photovoltaic panel 210 can be clamped on both sides of the bracket member 112.

The distance between the first support leg 121 and the bracket member 112 gradually expands in a direction away from the bottom plate 111, and the distance between the second support leg 131 and the bracket member 112 gradually expands in a direction away from the bottom plate 111. One end of the clamping member 142 is clamped with the first support leg 121, and the other end is clamped with the second support leg 131. The clamping member 142 is used to clamp the photovoltaic panel 210, and a cavity 141 is provided on the side of the clamping member 142 away from the second support leg 131.

[0054] Referring to FIG. 2 , in this embodiment, the distance between the first support leg 121 and the bracket member 112 gradually expands in the direction away from the bottom plate 111, and the distance between the second support leg 131 and the bracket member 112 gradually expands in the direction away from the bottom plate 111, so that the first support leg 121 and the second support leg 131 inclined to the same side of the bracket member 112 can clamp a clamping member 142, and the clamping member 142 will not be interfered by the bracket member 112. The clamping member 142 is clamped by the second support leg 131 and the first support leg 121 located on the same side of the bracket member 112, respectively, so that a photovoltaic panel 210 can be clamped on one side of the bracket member 112, and the edge of the other side, i.e. The bracket member 112 is a bracket member 112. The mounting structure 100 of the solar photovoltaic device of this embodiment is located at the edge of the solar photovoltaic device, that is, the edge edging portion, which is equivalent to the external skeleton structure of the solar photovoltaic device. From the installation position to the photovoltaic panel 210 and then to the cover plate 150, the side that does not clamp the photovoltaic panel 210 is the outer side of the solar photovoltaic device. The bracket member 112 serves as a wall to enclose the gap on the side of the photovoltaic panel 210 of the solar photovoltaic device close to the base, thereby preventing wind from blowing through the gap between the photovoltaic panel 210 and the base, avoiding the wind from exerting force on the photovoltaic panel 210 to separate from the base, thereby enhancing the stability of the solar photovoltaic device.

The two clamping members 142 are respectively located on both sides of the bracket member 112, one end of the clamping member 142 is clamped with the first support leg 121, and the other end is clamped with the second support leg 131. The clamping member 142 is used to clamp the photovoltaic panel 210, and a cavity 141 is provided on the side of the clamping member 142 away from the second support leg 131; in the second installation structure, the first support assembly 120 includes a first support leg 121, the second support assembly 130 includes a second support leg 131, and the clamping assembly 140 includes a clamping member 142, the first support leg 1 21. The second supporting leg 131 and the clamping member 142 are located on the same side of the bracket member 112. The distance between the first supporting leg 121 and the bracket member 112 gradually expands in the direction away from the bottom plate 111. The distance between the second supporting leg 131 and the bracket member 112 gradually expands in the direction away from the bottom plate 111. One end of the clamping member 142 is clamped with the first supporting leg 121, and the other end is clamped with the second supporting leg 131. The clamping member 142 is used to clamp the photovoltaic panel 210. A cavity 141 is provided on the side of the clamping member 142 away from the second supporting leg 131.

[0072] 3 , the edge of the photovoltaic panel 210 at the edge of the solar photovoltaic device away from the center of the solar photovoltaic device is clamped by at least one second mounting structure; any two photovoltaic panels 210 are clamped by the first mounting structure.

[0073] During the actual installation of the solar photovoltaic device, the base plate 111 is set at the location to be installed, such as a roof or a mountain. Since one end of the clamping assembly 140 is clamped with the first support assembly 120 and the other end is clamped with the second support assembly 130, and the cover plate 150 is set on the side of the clamping assembly 140 away from the second support assembly 130, a cylindrical cavity is formed between the cover plate 150, the first support assembly 120, the second support assembly 130 and the base. The cover plate 150 is set on the side of the clamping assembly 140 away from the second support assembly 130 and covers the cavity 141, so that when liquids such as rainwater seep into the cylindrical cavity formed between the cover plate 150, the first support assembly 120, the second support assembly 130 and the base through the gap between the cover plate 150 and the clamping assembly 140, due to the cavity 141, 1 and the cover plate 150 have a relatively large gap, so rainwater and other liquids will enter the space between the cavity 141 and the cover plate 150, and because the mounting structure 100 of the solar photovoltaic device is in the shape of a strip, the space between the cavity 141 and the cover plate 150 is in the shape of a strip parallel to the mounting structure 100 of the solar photovoltaic device and has openings at both ends, so the liquid entering the space between the cavity 141 and the cover plate 150 will be discharged from the openings on both sides, avoiding the liquid from entering the cylindrical cavity formed between the cover plate 150, the first support assembly 120, the second support assembly 130 and the base due to capillary phenomenon, thereby affecting the working performance of the photovoltaic panel 210 and even causing a short circuit in the internal circuit. The bracket members 112 of the multiple second mounting structures serve as a wall to enclose the space on the side of the photovoltaic panel 210 of the solar photovoltaic device close to the base, thereby preventing wind from blowing through the space between the photovoltaic panel 210 and the base, avoiding the wind from generating a force to separate the photovoltaic panel 210 from the base, thereby enhancing the stability of the solar photovoltaic device.
