Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel buckles, and in particular to a windproof buckle structure for a photovoltaic panel. Background Art

[0002] At present, there are a large number of mountain photovoltaic and rooftop photovoltaic stations on the market. Some photovoltaic areas have rich wind resources, which causes photovoltaic panels to be blown away, causing many problems. First, almost all the photovoltaic panels that are blown away are broken. Second, the photovoltaic panels that are blown away will hit other photovoltaic panels that are working normally, causing batch damage. Third, the photovoltaic panels themselves are heavy, and being blown away and falling may cause injuries to inspection personnel and surrounding residents or even more serious consequences, which not only affects the normal power generation of photovoltaic strings, but also poses a huge hidden danger to personal safety and equipment facilities.

[0003] At present, the existing photovoltaic panel clips still use the original simple clips in the plains. The advantages are low cost, less materials and simple installation, but the disadvantages are also particularly obvious. First, the aluminum clips are thin and easy to deform and bend inward, and cannot lock the photovoltaic panel; second, the clips have plastic accessories, and the site is hot all year round, so they are easy to soften and deform, and the temperature difference between day and night is large, so they are easy to weather and age; third, the contact surface between the clips and the photovoltaic panel is too smooth and the friction is small, so the photovoltaic panel is very easy to slip and lose stability. Therefore, in order to better improve the stability of the photovoltaic panel clip installation, and at the same time for the industry's technological progress and to improve the competitiveness of core technologies, this application proposes a new implementation plan that is different from the photovoltaic panel clip structure and application method in the prior art. Summary of the Invention

[0004] (1) Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a windproof clip structure for photovoltaic panels, which is mainly used to solve the problem that the photovoltaic panels are blown away and damaged due to poor stability of the clip installation.

[0005] (2) Technical solution To achieve the above object, the present invention provides the following technical solutions: A photovoltaic panel windproof buckle structure includes a card seat and a photovoltaic bracket, wherein upper buckle plates are integrally formed on both sides of the card seat, slide grooves are opened on both sides of the card seat, and the inner wall of the slide groove is slidably connected to the lower buckle plate, the top of the card seat is integrally formed with a sheath, and a fixing bolt is inserted into the sheath, the card seat and the top of the upper buckle plate are provided with a cover plate, and the bottom of the cover plate is rotatably connected to a rotating shaft, one side of the rotating shaft is fixedly connected to a connecting arm, and the bottom of the connecting arm is fixedly connected to a gear, and one end of the connecting arm is threadedly connected to an adjusting screw. The screw is threadedly connected to the mounting bracket at the bottom of the adjusting screw, and a gasket is fixedly connected to the bottom of the mounting bracket, which is a quartz wool pad. A groove is provided on the top of the upper buckle plate, and teeth are provided on the side walls of the groove. The teeth are engaged with the gear, and a plug hole is provided on the inner wall of the bottom of the groove, and a rotating shaft is inserted into the plug hole. The base, upper buckle plate and cover plate are integrally pressed from 6061-T6 aluminum alloy. The surfaces of the base, upper buckle plate and cover plate are micro-arc oxidized to form a ceramic layer with a thickness of 15-20µm.

[0006] Furthermore, anti-slip grooves are provided at the bottom of the upper buckle plate and the top of the lower buckle plate, and the anti-slip grooves are arc-shaped structures.

[0007] On the basis of the above-mentioned solution, the bottom of the liner is provided with anti-skid protrusions, and the anti-skid protrusions are semicircular in structure.

[0008] As a further solution of the present invention, fastening screws are inserted into the top of the cover plate and the base, and the fastening screws are threadedly connected to the lower buckle plate.

[0009] Furthermore, a reinforcing rib is fixedly connected to the inner side of the holder, and the reinforcing rib is a triangular structure.

[0010] On the basis of the above solution, an inner groove is provided on the top of the cover plate, and the inner groove is engaged with the top of the card seat.

[0011] As a further solution of the present invention, a frame is clamped between the upper and lower buckle plates, and a photovoltaic panel is clamped on the inner side of the frame, the gasket is in contact with the photovoltaic panel, and the mounting frame is in contact with the edge of the frame.

[0012] Furthermore, the photovoltaic bracket and the holder are threadedly connected via fixing bolts.

[0013] (3) Beneficial effects Compared with the prior art, the present invention provides a windproof buckle structure for photovoltaic panels, which has the following beneficial effects: 1. The buckle structure uses the teeth in the groove of the upper buckle plate to cooperate with the gear to provide locking force to the connecting arm, effectively preventing the movement of the connecting arm and increasing its stability. A quartz wool pad is provided at one end of the connecting arm. Its excellent heat resistance, weathering resistance and good friction coefficient ensure that the photovoltaic panel can remain stable even in extreme weather and prevent skidding.

[0014] 2. The buckle structure adopts 6061-T6 aluminum alloy material, and the surface is micro-arc oxidized to form a ceramic layer, which not only improves the strength and corrosion resistance, but also enhances the temperature resistance, so that it can maintain long-term stability in extreme temperature difference environments, abandoning traditional plastic accessories, and is not affected by the year-round high temperature and large temperature difference between day and night in the site, reducing weathering and aging.

[0015] 3. The buckle structure, by setting inner grooves on the cover plate, makes the bottom of the cover plate located on both sides of the top of the card holder, and the cover plate is located directly above the fixing bolts. This can not only prevent the card holder from deforming and bending inward, making it impossible to lock the photovoltaic panel, but also prevent the fixing bolts from slipping and detaching from the photovoltaic bracket, affecting its installation stability.

One end of 13 is threadedly connected to an adjusting screw 16, and the bottom of the adjusting screw 16 is threadedly connected to a mounting bracket 15. A gasket 17 is fixed to the bottom of the mounting bracket 15 by bolts. The gasket 17 is a quartz wool pad that can withstand extreme temperature environments of -40°C to 800°C, suitable for mountain photovoltaic scenes with large temperature differences between day and night. Its weathering resistance is better than that of ordinary organic materials, and its service life can reach more than 15 years. The fiber structure can effectively disperse impact force and reduce stress concentration between the photovoltaic panel and the buckle. The surface friction coefficient can reach μ ≥ 0.6, enhancing the anti-slip effect. A groove 8 is provided at the top of the upper buckle plate 2, and teeth 9 are provided on the side walls of the groove 8. The teeth 9 are engaged with the gear 14. A plug hole 10 is provided on the bottom inner wall of the groove 8, and a rotating shaft 12 is inserted into the plug hole 10. The base 1, the upper buckle plate 2 and the cover plate 11 are integrally pressed from 6061-T6 aluminum alloy. The surfaces of the base 1, the upper buckle plate 2 and the cover plate 11 are micro-arc oxidized to form a ceramic layer with a thickness of 15-20µm.

[0020] Among them, the bottom of the upper gusset plate 2 and the top of the lower gusset plate 4 are provided with anti-slip grooves 5, which are arc-shaped structures. The arc-shaped structure can disperse impact force, improve friction, and improve wind pressure resistance by more than 40%. The bottom of the gasket 17 is provided with anti-slip bumps 18, and the anti-slip bumps 18 are semicircular structures. The cover plate 11 and the top of the base 1 are plugged with fastening screws 19, and the fastening screws 19 are threadedly connected to the lower gusset plate 4. A reinforcing rib 20 is welded on the inner side of the base 1, and the reinforcing rib 20 is a triangular structure.
