[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a fixing platform suitable for photovoltaic components and a photovoltaic support module. Background Art

[0002] Solar energy has been increasingly used as a clean and renewable energy source. Photovoltaic support modules use solar photovoltaic components as photoelectric conversion devices to convert solar energy into electrical energy. With the development of photovoltaic support modules, photovoltaic support modules have become more and more diverse. Conventional photovoltaic support modules are directly installed on the ground. This installation method has relatively high requirements on the soil quality of the installation location and also requires a relatively large installation space. Therefore, our company has applied for a patent with application number CN2023114919152, disclosing a dual-axis tracking photovoltaic bracket and photovoltaic device with folding and wind-resistant functions, wherein the disclosed photovoltaic device can be installed on a fixed column (for example: a street lamp pole or a pole).

[0003] The existing brackets are not sufficient to stably support photovoltaic panels, which will not only affect the accuracy of photovoltaic tracking and the power generation efficiency of photovoltaic panels, but also cause photovoltaic panels to loosen or fall off easily. How to stably support photovoltaic devices has become a technical problem that needs to be solved urgently. Utility Model Content

[0028] The utility model has the advantages of increasing the overall strength and stability of the fixed platform and improving the stability of the photovoltaic components connected to the fixed platform.

[0029] First, the first end of the first support rod and the first end of the second support are connected to the outside, and the photovoltaic assembly is connected to the outside through a fixed platform, and the fixed platform is supported by the extended end of the abutment rod below the connection between the first end of the first support rod and the first end of the second support and the outside, so as to prevent the fixed platform from turning around the connection between the first end of the first support rod and the first end of the second support and the outside;

When the fixed platform is connected to the fixed column, the contact area between the first connection part, the second connection part and the abutting part and the fixed column can be increased, thereby increasing the friction force, avoiding displacement of the fixed platform relative to the external fixed column, and making the fixed platform more stable in supporting the photovoltaic module.

[0032] Third, the first support rod and the second support rod are connected by a connecting rod, the proximal end of the first support rod is connected with the proximal end of the second support by the first connecting rod, and the proximal tail end of the first support rod is connected with the proximal tail end of the second support by the first connecting rod, so as to increase the strength between the first support rod and the second support rod, and prevent the first support rod and the second support rod from separating and slipping off the fixed column.

[0033] Fourth, since the first support rod, the second support rod, the connecting rod and the abutting rod are all square tubes, the overall deadweight of the fixed platform is reduced. At the same time, reinforcing ribs are provided on the inner wall of any end of the square tube to increase the strength of the first support rod, the second support rod, the connecting rod and the abutting rod, thereby increasing the overall strength of the fixed platform.

[0034] Fifth, by connecting the first reinforcement, the second reinforcement and the third reinforcement to the fixed column, the first connection part is connected to the first reinforcement, the second connection part is connected to the second reinforcement, and the abutment part is connected to the third reinforcement, so as to avoid displacement of the fixed platform when connecting to the photovoltaic module, and make the fixed platform support the photovoltaic module more stably.

[0051] As a first aspect of this embodiment, Figures 1 to 4 As shown, a fixing platform suitable for photovoltaic modules includes:

[0052] A first support rod 1, one end of which is a head end and the other end is a tail end;

[0053] The second support rod 2 has one end as the head end and the other end as the tail end, and forms an "eight" shape with the first support rod 1. The head end of the first support rod 1 is closer to the head end of the second support rod 2, and the tail end of the first support rod 1 is farther from the tail end of the second support rod 2. The head end of the first support rod 1 and the head end of the second support rod are both connected to the outside;

[0054] A connecting rod 3, used to connect the first supporting rod 1 and the second supporting rod 2;

[0055] An abutment rod 4, one end of which is connected to the first support rod 1 and / or the connecting rod 3, or one end of which is connected to the second support rod 2 and / or the connecting rod 3, and the other end of which extends below the connection between the head end of the first support rod 1 and the head end of the second support and the outside, and the extended end abuts against the outside.

[0056] It should be noted that, in this embodiment, in order to increase the friction between the first end of the first support rod 1 and the first end of the second support and the connection, the fixed platform further includes a first connection part 11, a second connection part 21 and a third connection part;

[0057] The first connection portion 11 is connected to the head end of the first support rod 1, and the first support rod 1 is connected to the outside through the first connection portion 11, and the connection between the first connection portion 11 and the outside is in close contact;

[0058] The second connection portion 21 is connected to the head end of the second support rod 2, and the second support rod 2 is connected to the outside through the second connection portion 21, and the connection between the second connection portion 21 and the outside fits together;

[0059] The abutment portion 41 is connected to the extended end of the abutment rod 4, and the abutment rod 4 abuts against the outside through the abutment portion 41, and the connection between the abutment portion 41 and the outside fits;

[0060] Thereby, the contact area between the first end of the first support rod 1 and the first end of the second support and the connection is increased, thereby increasing the friction force between the first end of the first support rod 1 and the first end of the second support and the connection.

[0061] It should be noted that, in this embodiment, the fixed platform applicable to the photovoltaic module (hereinafter referred to as the fixed platform) disclosed in this embodiment can be connected to a plane such as a wall, or can be connected to a fixed column;

[0062] When the fixed platform is connected to a plane such as a wall, the first support rod 1 of the fixed platform is directly connected to the plane such as the wall through the first connection part 11 by bolts, and the second support rod 2 of the fixed platform is directly connected to the plane such as the wall through the second connection part 21 by bolts.

[0063] When the fixed platform is connected to the fixed column, the following methods can be used, for example:

[0064] First, a U-shaped bolt is used to sleeve the U-shaped bolt on the fixing column, and the two ends of the U-shaped bolt are respectively connected to the first connecting end 111 of the first connecting part 11 and the second connecting end 211 of the second connecting part 21, and the fixing platform is clamped on the fixing column through the U-shaped bolt, the first connecting part 11 and the second connecting part 21;

[0065] Second, using a connecting block with an arc-shaped groove, one end of the connecting block is connected to the first connecting end 111 of the first connecting part 11 by bolts, and then the other end of the connecting block is connected to the second connecting end 211 of the second connecting part 21 by bolts. The fixed platform is clamped on the fixed column through the connecting block, the first connecting part 11 and the second connecting part 21.

[0066] Further, in this embodiment, when the fixed platform is connected to the fixed column, the contact surface between the first connecting portion 11 and the outside is the first abutting surface, the contact surface between the second connecting portion 21 and the outside is the second abutting surface, and the contact surface between the abutting portion 41 and the outside is the third abutting surface; Figures 1 to 4 As shown, the first abutting surface, the second abutting surface and the third abutting surface are all arc surfaces.

[0067] Since the first abutting surface and the second abutting surface are both arc surfaces for fitting with the fixing column, when the fixing platform is connected to the fixing column without damaging the fixing column, one end of the first connecting portion 11 away from the second connecting portion 21 extends radially along the first abutting surface to form a first connecting end 111, and one end of the second connecting portion 21 away from the first connecting portion 11 extends radially along the second abutting surface to form a second connecting end 211; the first connecting portion 11 is conveniently connected to the matching parts on the fixing column through the first connecting end 111, and the second connecting portion 21 is conveniently connected to the matching parts through the second connecting end 211, and the matching parts include but are not limited to U-bolts and connecting blocks with arc-shaped grooves.

[0068] It should be noted that the first connection part 11 and the second connection part 21 can be set separately, or the end of the first connection part 11 close to the second connection part 21 can extend toward the second connection part 21 to be connected to the second connection part 21. The first connection part 11 and the second connection part 21 are used to form a whole. This can prevent the first connection part 11 and the second connection part 21 from separating from the fixed column and slipping off the fixed column when the fixed platform is connected to the fixed column, thereby preventing the first support rod 1 and the second support rod 2 from being stretched apart and damaging the fixed platform.

[0069] Further, in this embodiment, when the number of the connecting rods 3 is more than two, preferably, Figures 1 to 4 As shown, the connecting rod 3 includes at least two, the first connecting rod 3 is connected to the proximal end of the first support rod 1 and the proximal end of the second support, and the second connecting rod 3 is connected to the proximal end of the first support rod 1 and the proximal end of the second support. The strength between the first support rod 1 and the second support rod 2 can be greatly increased to prevent the first connecting portion 11 and the second connecting portion 21 from being separated from the fixing column due to the first support rod 1 and the second support rod 2 being stretched apart.

[0070] To facilitate the connection between the first support rod 1 and the second support rod 2 and the fixing column, Figures 1 to 4 As shown, the first end of the first support rod 1 is provided with a first connection portion 11, and the first support rod 1 is connected to the outside through the first connection portion 11; the first end of the second support rod 2 is provided with a second connection portion 21, and the second support rod 2 is connected to the outside through the second connection portion 21;

[0071] In order to facilitate the abutment of the abutment rod 4 with the fixed column, as Figures 1 to 4 As shown, an abutment portion 41 is provided at the extended end of the abutment rod 4 , and the abutment rod 4 abuts against the outside through the abutment portion 41 .

[0072] It should be noted that, in this embodiment, when the connecting rod 3 is connected to the lower part of the first support rod 1 and the second support rod 2, the first support rod 1 and the second support rod 2 constitute a mounting portion, and when the connecting rod 3 is connected to the ends of the first support rod 1 and the second support rod 2, the first support rod 1, the second support rod 2 and the connecting rod 3 constitute a mounting portion. Preferably, as shown in FIG. Figure 4 As shown, the connecting rod 3 is connected above the first support rod 1 and the second support rod 2, and the connecting rod 3 constitutes a mounting portion, and the photovoltaic assembly can be connected to the mounting portion.

[0073] It should be noted that, in this embodiment, the abutment rod 4 is used to support the bottom end of the fixed platform when the first connection part 11 and the second connection part 21 are hooped on the fixed column. Under the gravity of the photovoltaic module, the fixed platform has a tendency to flip downward around the first connection part 11 and the second connection part 21. The abutment rod 4 is used to support the bottom of the first connection part 11 and the second connection part 21, so as to improve the stability of the fixed platform.

[0074] At the same time, under the action of gravity of the photovoltaic module, the friction force of the extended end of the abutment rod 4 relative to the fixed column is increased, preventing the fixed platform proposed in this embodiment from sliding downward along the fixed column, ensuring that the fixed platform supports the photovoltaic module more stably.

[0075] Furthermore, in this embodiment, in order to increase the stability of the abutment rod 4, as Figures 1 to 4 As shown, two abutment rods 4 are provided, the two abutment rods 4 are respectively connected to the first support rod 1 and the second support rod 2, and are respectively located directly below the first support rod 1 and the second support rod 2, and the extended ends of the two abutment rods 4 can abut against the vertical rods.

[0076] It should be noted that more than two abutment rods 4 may be provided. When the number of abutment rods 4 is greater than two, two of them preferably adopt the aforementioned Figures 1 to 4 The remaining abutment rods 4 can be directly connected to the connecting rod 3.

[0077] It should also be noted that, in the present embodiment, the abutment rod 4 is described as being connected to the first support rod 1 and the second support rod 2. In fact, the abutment rod 4 may also be directly connected to the connecting rod 3 without being connected to the first support rod 1 and / or the second support rod 2; one abutment rod 4 may also be connected to both the connecting rod 3 and the first support rod 1, and another abutment rod 4 may be connected to both the connecting rod 3 and the second support rod 2.

[0078] It should be noted that, in this embodiment, in order to increase the overall strength of the fixed platform, the first support rod 1, the second support rod 2, the connecting rod 3 and the abutting rod 4 are all pipe fittings, and reinforcing ribs are provided on the inner walls thereof.

[0079] It should be noted that, in this embodiment, in order to reduce the deadweight of the fixed platform, the first support rod 1, the second support rod 2, the connecting rod 3 and the abutting rod 4 are all key, preferably, as Figures 1 to 4 As shown, the first support rod 1, the second support rod 2, the connecting rod 3 and the abutting rod 4 are all square tubes. At the same time, in order to increase the strength of the first support rod 1, the second support rod 2, the connecting rod 3 and the abutting rod 4, reinforcing ribs are provided on the inner wall of any end of the square tube, thereby increasing the overall strength of the fixed platform.

[0080] As a second aspect of this embodiment, Figure 2 and Figure 4 As shown, a photovoltaic support module comprises two sets of fixing platforms suitable for photovoltaic modules as described above, and the two sets of fixing platforms are relatively connected to fixing columns;

[0081] The head end of the first support rod 1 of the first fixed platform is connected to the head end of the second support rod 2 of the second fixed platform;

[0082] The head end of the second support rod 2 of the first fixed platform is connected to the head end of the first support rod 1 of the second fixed platform, and the two fixed platforms are clamped on the fixed column through the first support rod 1 and the second support rod 2.

[0083] It should be noted that, in this embodiment, in order to increase the stability of the photovoltaic support module, Figure 2 and Figure 4 As shown, a first reinforcement member 5 is provided between the first connection portion 11 of the first group of fixed platforms and the second connection portion 21 of the second group of fixed platforms, and the first reinforcement member 5 is connected to the fixed column. The connection method of the first reinforcement member 5 includes but is not limited to: bolts are sequentially passed through the first connection portion 11 of the first group of fixed platforms, the first reinforcement member 5 and the second connection portion 21 of the second group of fixed platforms, and connected and fixed.
