Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic assembly devices, and in particular to a wind pressure resistant block structure for a solar photovoltaic assembly. Background Art

[0002] With the in-depth implementation of the national dual-carbon strategy, photovoltaic new energy has been widely developed and constructed. China's terrain is complex and diverse, with five types of terrain: plains, plateaus, mountains, hills, and basins. The complex and diverse terrain has formed complex and diverse wind pressures, especially on the roofs of super-high-rise buildings and in the seaside areas. The wind is very strong, which poses a challenge to the wind resistance and stability of photovoltaic brackets. In the entire photovoltaic bracket structure, the connection between the component and the guide rail is a weak area. As long as the stability of the connection is guaranteed under the action of wind, the entire bracket structure can be stable; conventional components and guide rails are connected by pressing blocks and rectangular nuts. This structure is easy to install and can remain stable under conventional wind.

[0003] The shortcoming of the existing technology is that under wind speeds of 10 or above, this connection structure is prone to instability and cause the component to be overturned. The main reason is that under the action of strong wind force, especially under the repeated action of wind load in two directions, the rectangular nut is easy to rotate. When the rectangular nut is rotated to a certain angle, the rotation radius of the rectangular nut is smaller than the size of the guide rail slot, and the entire pressure block, nut and upper component will be overturned. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art. To achieve the above purpose, a wind-resistant block structure for a solar photovoltaic module is used to solve the problems raised in the above background technology.

[0005] A wind pressure resistant block structure for a solar photovoltaic module, comprising:

[0006] Limiting guide rails;

[0007] A locking assembly disposed inside the limiting guide rail; and

[0008] A photovoltaic panel fastener disposed on the outside of the limiting guide rail;

[0009] The positioning assembly is arranged inside the limiting guide rail to form an integrated structure with the photovoltaic panel fastener, and when sliding to the position to be fixed, the photovoltaic panel fastener is fixedly fastened and constrained. This design makes the installation and fixation of the photovoltaic panel fastener more accurate and efficient, reduces errors during the installation process, and improves the stability and safety of the entire photovoltaic system.

[0010] As a further technical solution of the present invention: the position-limiting guide rail includes a guide rail groove and at least one guide rail vertical plate arranged in the guide rail groove. The design of the guide rail groove and the guide rail vertical plate enhances the structural strength of the position-limiting guide rail, enables it to withstand greater external force and pressure, and can be used for subsequent structural position limiting.

[0011] As a further technical solution of the present invention: the positioning assembly includes a circular nut, a slot provided in the circular nut, and a buckle provided outside the circular nut. This design enables the positioning assembly to be firmly fixed on the limiting guide rail, and the design of the buckle makes the installation and removal process more convenient and quick.

[0012] As a further technical solution of the present invention: the diameter of the circular nut is greater than the width of the guide rail groove. This design ensures the stability of the circular nut in the guide rail groove and prevents it from falling off or loosening due to external force.

[0013] As a further technical solution of the present invention: the buckle is made of an elastic plastic part. The use of the elastic plastic part enables the buckle to better adapt to photovoltaic panel fasteners of various shapes and sizes during the fixing process, thereby improving the flexibility and adaptability of the installation.

[0014] As a further technical solution of the present invention: the photovoltaic panel fastener includes a screw rod arranged on a circular nut, and a photovoltaic panel pressing block arranged on the outside of the limiting guide rail. The design of the screw rod and the photovoltaic panel pressing block enables the photovoltaic panel to be firmly fixed on the limiting guide rail, preventing the photovoltaic panel from loosening or falling off due to wind or other external factors.

[0015] As a further technical solution of the present invention: the position limiting guide rail and the photovoltaic panel pressing block are both U-shaped structures. The design of the U-shaped structure enhances the strength and stability of the position limiting guide rail and the photovoltaic panel pressing block, so that they can better withstand various external forces and pressures.

[0016] As a further technical solution of the present invention: the photovoltaic panel pressing block is provided with a protrusion for fixing the photovoltaic panel. The design of the protrusion enables the photovoltaic panel to be more firmly fixed on the photovoltaic panel pressing block, thereby improving the stability and safety of the entire photovoltaic system.

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] By adopting the above technical solution, an innovative fixing method for photovoltaic panel installation is realized by designing a limit rail, setting a positioning component on the inner side thereof, and configuring photovoltaic panel fasteners on the outer side. In specific operation, the positioning component is arranged on the inner side of the limit rail and combined with the photovoltaic panel fasteners into an integrated structure. After sliding to a predetermined fixed position, the positioning component can effectively perform fixed-point fastening constraints on the photovoltaic panel fasteners. This solution provides a more convenient and stable photovoltaic panel installation and fixing method, enhances the structural safety and installation efficiency of the photovoltaic system, simplifies the installation process, and reduces maintenance costs.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to Figure 1 and Figure 2 In an embodiment of the present invention, a wind pressure resistant block structure for a solar photovoltaic module includes:

[0025] Limiting guide rail 1;

[0026] A locking assembly 2 disposed inside the limiting guide rail 1; and

[0027] A photovoltaic panel fastener 3 disposed on the outer side of the limiting guide rail 1;

[0028] The positioning assembly 2 is arranged on the inner side of the limiting guide rail 1 to form an integrated structure with the photovoltaic panel fastener 3 , and when sliding to the position to be fixed, the photovoltaic panel fastener 3 is fastened and constrained at a fixed point.

[0029] In this embodiment, the position-limiting guide rail 1 includes a guide rail groove 11 and at least one guide rail vertical plate 12 disposed in the guide rail groove 11 .

[0030] In a specific embodiment, the cross-sectional form of the guide rail groove 11 is slightly changed, and two vertical plates are added to the cross section;

[0031] In this embodiment, the locking assembly 2 includes a circular nut 21 , a locking groove 22 disposed on the circular nut 21 , and a buckle 23 disposed on the outer side of the circular nut 21 .

[0032] The diameter of the circular nut 21 is greater than the width of the guide rail groove 11 , and the buckle 23 is made of an elastic plastic part.

[0033] In a specific embodiment, the rectangular nut is changed into a circular nut 21, and a sliding slot 22 is provided at the corresponding position of the guide rail vertical plate 12. The circular nut 21 is placed in the guide rail slot 11 with a specially matched plastic buckle 23;

[0034] In this embodiment, the photovoltaic panel fastener 3 includes a screw rod 31 disposed on the circular nut 21 , and a photovoltaic panel pressing block 32 disposed on the outer side of the limiting guide rail 1 .

[0035] In this embodiment, the limiting guide rail 1 and the photovoltaic panel pressing block 32 are both U-shaped structures.

[0036] In this embodiment, the photovoltaic panel pressing block 32 is provided with a protrusion 320 for fixing the photovoltaic panel.

[0037] In a specific embodiment, the photovoltaic panel pressing block 32, the plastic buckle 23, the round nut 21 and the screw 31 are assembled into a whole, which is specifically: after installation, the original fixed-point installation design at the photovoltaic component is changed to an integral sliding installation, and after the assembly is completed, it slides from both ends of the limit guide rail 1 to the photovoltaic component position;

[0038] The above whole slides from the end of the limiting guide rail 1 along the middle to the corresponding position of the photovoltaic module;

[0039] Tighten the screw 31 so that the protrusion 320 of the photovoltaic panel pressing block 32 presses the photovoltaic assembly;

[0040] Beneficial effects:

[0041] Through the above design, under extreme wind speed;

[0042] Since the circular nut 21 is circular, the radius of rotation in all directions is the same and is greater than the width of the guide rail groove 11. No matter how the nut rotates under the action of wind force, the limit guide rail 1 always has a downward constraint on it, and the node can remain stable under the action of wind suction;

[0043] Due to the presence of the slot 22 on the nut, the slot 22 and the guide rail vertical plate 12 can be well engaged. Under the action of wind suction, the vertical plate also has a downward constraint on the nut, further increasing the stability of the node under the action of wind suction;

[0044] Through the above two analyses, it can be seen that this structure can resist extreme wind forces very well.

[0045] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
