Description

Technical Field

[0001] The utility model relates to a height-adjusting bracket device for an offshore photovoltaic grid frame. Background Art

[0002] With the development of the global economy and the growth of the population, the energy demand continues to rise. Traditional fossil energy not only has limited reserves, but also causes serious pollution to the environment during the exploitation and use process.

[0003] Therefore, as a new type of clean energy, offshore photovoltaic has gradually attracted global attention with its unique advantages.

[0004] As one of the structures of the offshore photovoltaic grid frame design, the square pyramid bolted spherical photovoltaic grid frame is increasingly favored by the current society due to its advantages such as relatively simple structure and short installation period;

[0005] However, for the bolted spherical grid frame structure recorded in the patent document such as Chinese Patent Publication No. CN201936897U, during the design process, considering the influence of force factors and economy, etc., there are different structure size selections for the upper chord members, resulting in height deviations of the upper chord members on the plane.

[0006] The installation of photovoltaic panels requires being on the same upper chord plane. Now, affected by the height deviation of the upper chord members, it is difficult to meet the requirement of the same plane height during the installation of photovoltaic panels. Content of the Utility Model

[0007] The purpose of the utility model is to provide a technical solution of a height-adjusting bracket device for an offshore photovoltaic grid frame aiming at the deficiencies of the existing technology, which can raise the photovoltaic panel components corresponding to the upper chord members with smaller sizes, so that the photovoltaic panel components can be kept on the same plane.

[0008] To solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A height-adjusting bracket device for an offshore photovoltaic grid frame includes

[0010] an upper chord member for installing photovoltaic panel components;

[0011] It further includes a transverse connecting plate and a longitudinal fixing plate. The transverse connecting plate is located below the photovoltaic panel components. The transverse connecting plate is used to support the photovoltaic panel components and is fixedly connected to the photovoltaic panel components; the longitudinal fixing plate is connected between the transverse connecting plate and the upper chord member. The longitudinal fixing plate is used to establish the connection between the transverse connecting plate and the upper chord member and fix them to each other, and at the same time can increase the distance between the transverse connecting plate and the upper chord member.

[0012] By adopting the above technical solution, the transverse connecting plate can be fixedly connected to the photovoltaic panel assembly. The longitudinal fixing plate increases the distance between the transverse connecting plate and the upper chord, causing the photovoltaic panel assembly corresponding to the smaller-sized upper chord to be lifted upward, so that the photovoltaic panel assembly can be kept on the same plane.

[0013] Further, an extension plate is formed on one side of the transverse connecting plate, and mounting holes are formed through the surface of the extension plate. The mounting holes are used to cooperate with bolts to achieve the fitting and fixing of the transverse connecting plate and the photovoltaic panel assembly.

[0014] Further, the mounting holes are strip-shaped holes.

[0015] Further, the longitudinal fixing plate and the transverse connecting plate are connected by welding.

[0016] Further, a groove adapted to the upper chord is formed at the bottom of the longitudinal fixing plate. The upper chord is embedded in the bottom of the longitudinal fixing plate through the groove, and the groove is used to increase the contact area between the longitudinal fixing plate and the surface of the upper chord.

[0017] Further, the longitudinal fixing plate and the surface of the upper chord are connected by welding.

[0018] Further, a first triangular structure is connected between the longitudinal fixing plate and the transverse connecting plate.

[0019] Further, a second triangular structure is connected between the longitudinal fixing plate and the upper chord.

[0020] Further, two longitudinal fixing plates are connected between the transverse connecting plate and the upper chord.

[0021] Further, a gap is formed between the two longitudinal fixing plates.

[0022] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0023] 1. The utility model can lift the photovoltaic panel assembly corresponding to the smaller-sized upper chord upward, so that the photovoltaic panel assembly can be kept on the same plane;

[0024] 2. The transverse connecting plate of the utility model is connected to the photovoltaic panel assembly by bolts, which is convenient for installation;

[0025] 3. The mounting holes of the transverse connecting plate in the utility model are strip-shaped holes, which increases the adjustable range during bolt connection, and the photovoltaic panel assembly can be flexibly adjusted according to its position deviation during actual installation;

[0026] 4. The bracket device of the utility model includes a first triangular structure and a second triangular structure, which are used to enhance the structural stability of the overall bracket device. Description of the Drawings

[0041] Embodiment 1

[0042] A height-adjusting bracket device for an offshore photovoltaic grid frame is applied between a photovoltaic panel assembly 7 and the upper chord 5 of the photovoltaic grid frame;

[0043] This height-adjusting bracket device includes a transverse connecting plate 1 and a longitudinal fixing plate 2;

[0044] The transverse connecting plate 1 is located below the photovoltaic panel assembly 7, as Figure 6 shown, and the transverse connecting plate 1 is used to support the photovoltaic panel assembly 7;

[0045] The transverse connecting plate 1 is fixedly connected to the photovoltaic panel assembly 7;

[0046] The longitudinal fixing plate 2 is located below the transverse connecting plate 1 and is perpendicular to it, as Figure 3 、 Figure 6 shown;

[0047] One end of the longitudinal fixing plate 2 is welded to the bottom of the transverse connecting plate 1;

[0048] The longitudinal fixing plate 2 is connected between the transverse connecting plate 1 and the upper chord 5, and is used to establish the connection between the transverse connecting plate 1 and the upper chord 5 and fix the two to each other, as Figures 1 to 3 shown;

[0049] The bottom end of the longitudinal fixing plate 2 is fixedly connected to the upper chord 5;

[0050] The longitudinal fixing plate 2 has a certain length, which can increase the distance between the transverse connecting plate 1 and the upper chord 5;

[0051] When the photovoltaic panel assembly 7 is actually laid out, due to different structural size selections of the upper chord 5, there are height deviations on the laying plane. The increased length distance of the longitudinal fixing plate 2 is adapted to the actual existing height deviations, so as to compensate for the height deviations of the laying plane and enable the laid photovoltaic panel assembly 7 to be on the same plane.

[0052] In this embodiment, an extension plate 11 is formed on one side of the transverse connecting plate 1, as Figure 2 、 Figure 3 shown;

[0053] The surface of the extension plate 11 is penetrated with mounting holes 12, as Figure 4 、 Figure 5 shown;

[0054] A hole corresponding to the mounting hole 12 is provided on the edge frame of the photovoltaic panel assembly 7, and the screw 13 can pass through the hole and then correspondingly pass through the mounting hole 12, as Figure 6 shown;

[0055] The photovoltaic panel assembly 7 and the horizontal connecting plate 1 are fixed by the cooperation of the bolts 13, as Figure 6 shown.

[0056] In this embodiment, the mounting hole 12 is a slotted hole, as Figure 4 , Figure 5 shown;

[0057] Designing the mounting hole 12 as a slotted hole can increase the adjustable range during the connection of the bolt 13, and the photovoltaic panel assembly 7 can be flexibly adjusted according to the deviation of its position during actual installation.

[0058] In this embodiment, a total of two longitudinal fixing plates 2 are provided at the bottom of the horizontal connecting plate 1, as Figure 3 , Figure 4 shown;

[0059] Establishing the connection between the horizontal connecting plate 1 and the upper chord 5 through the two longitudinal fixing plates 2 can further increase the structural stability of this height-adjusting bracket device;

[0060] A gap 22 is formed between the two longitudinal fixing plates 2, and air can flow through the gap 22. By setting the gap 22, the windward area of this height-adjusting bracket device is reduced to a certain extent, thereby improving the stability of the device;

[0061] In this embodiment, a groove 21 adapted to the upper chord 5 is formed at the bottom of the longitudinal fixing plate 2, as Figure 4 , Figure 5 shown;

[0062] When the longitudinal fixing plate 2 is connected to the upper chord 5, the upper chord 5 is embedded in the groove 21, as Figure 2 shown. By setting the groove 21, the contact area between the longitudinal fixing plate 2 and the upper chord 5 is increased;

[0063] The longitudinal fixing plate 2 and the surface of the upper chord are connected by welding.

[0064] In this embodiment, a first triangular structure 3 is connected between the longitudinal fixing plate 2 and the horizontal connecting plate 1, as Figure 3 , Figure 4 shown;

[0065] The two right-angle sides of the first triangular structure 3 are respectively welded to the lower surface of the horizontal connecting plate 1 and the side wall of the longitudinal fixing plate 2;

[0066] The structural stability of the present height-adjustable bracket device can be improved by setting the first triangular structure 3.

[0067] In this embodiment, a second triangular structure 4 is connected between the longitudinal fixing plate 2 and the upper chord 5, as Figure 3 , Figure 5 shown;

[0068] The two right-angled sides of the second triangular structure 4 are respectively welded to the side wall of the longitudinal fixing plate 2 and the surface of the upper chord 5;

[0069] The structural stability of the present height-adjustable bracket device can be improved by setting the second triangular structure 4;

[0070] In this embodiment, an arc-shaped groove adapted to the upper chord 5 is formed on the right-angled side of the second triangular structure 4 that is attached to the surface of the upper chord 5. Through this arc-shaped groove, the contact area between this side right-angled side and the upper chord 5 can be increased, and the connection stability between the second triangular structure 4 and the upper chord 5 can be improved.

[0071] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present utility model to achieve substantially the same technical effects are all covered within the protection scope of the present utility model.
