Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and specifically relates to a snow-blocking clamp for photovoltaic modules. Background Technology

[0002] Photovoltaic power generation is one of the most widely used methods for producing clean electricity, and photovoltaic (PV) mounting systems are an important component in the construction of PV power plants. Because the surfaces of PV arrays on rural rooftops are relatively smooth, snow can easily slide off during snowfall, posing a risk of injury to people or property on the ground. Therefore, snow-blocking clamps for PV modules have been designed to reduce the hazards caused by snow sliding off the modules. However, current research on PV modules is limited, and the types and styles of designs are relatively simple, with low installation and fixing strength. Existing PV module snow-blocking clamps have weak load-bearing capacity between the vertical snow-blocking section and the horizontal support section. Under high snow loads, the bending moment is large, easily causing bending deformation, which affects the fixing effect between the snow-blocking clamp and the PV module frame. Furthermore, the clamping thickness of the snow-blocking clamp is relatively fixed, resulting in low applicability to module frames of different thicknesses, requiring readjustment of the clamping height.

[0003] Therefore, in order to address the above-mentioned technical problems, designing a snow-blocking clamp for photovoltaic modules to ensure the supporting strength of the snow-blocking clamp and to adapt to photovoltaic modules with different frame thicknesses, thereby improving the applicability of the device, is a technical problem that needs to be solved by those skilled in the art.

[0011] Preferably, the vertical snow shield is arranged perpendicularly to the upper horizontal fixing plate.

[0012] Preferably, the protruding slot extends toward the upper transverse fixing plate.

[0013] Preferably, the component frame includes a first mating surface that mates with the upper horizontal fixing plate, and a second mating surface that mates with the lower horizontal fixing plate and abuts against the outwardly protruding slot, wherein the first mating surface and the second mating surface are connected by a vertical partition.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide a snow-blocking clamp for photovoltaic modules, ensuring the support strength of the snow-blocking clamp and adapting to photovoltaic modules with different frame thicknesses, thereby improving the applicability of the device.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] refer to Figures 1-3 The photovoltaic module snow-blocking clamp disclosed in this embodiment of the utility model includes at least a module frame 11 for fixing the photovoltaic panel, an upper horizontal fixing plate 1 and a lower horizontal fixing plate 2 for clamping the module frame 11. The ends of the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 are simultaneously connected to a vertical snow-blocking plate 3. Fasteners are provided on the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2. The fasteners can adjust the distance between the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2. By setting the fasteners, the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 can clamp the module frame 11 of different thicknesses, improving the applicability of the snow-blocking clamp. Furthermore, by setting the module frame 11, the direct clamping of the photovoltaic panel can be avoided, ensuring the service life of the photovoltaic panel.

[0027] It should be noted that the main profiles of the upper horizontal fixing plate 1, the lower horizontal fixing plate 2, the component frame 11, and the vertical snow barrier plate 3 can be made of aluminum alloy. The profile mold of the main body of the snow barrier clamp can be designed and manufactured in the factory. The profile of the main body of the snow barrier clamp can be directly produced by extrusion through a casting machine. By cutting the produced profile to a fixed length, multiple snow barrier clamp bodies can be made. Then, bolt holes are made on a drilling machine to complete the production of the snow barrier clamp.

[0028] refer to Figure 1-2 In one embodiment, the fastener is a fixing bolt 6 that passes through the upper transverse fixing plate 1 and the lower transverse fixing plate 2. The upper transverse fixing plate 1 and the lower transverse fixing plate 2 are respectively provided with upper fixing plate bolt holes 8 and lower fixing plate bolt holes 5 that cooperate with the fixing bolt 6. The fixing bolt 6 cooperates with the nut to adjust the distance between the upper transverse fixing plate 1 and the lower transverse fixing plate 2.

[0029] It should be noted that the fixing bolt 6 can be a galvanized bolt or a stainless steel bolt. The bolt includes a nut, a screw, two flat washers, and a spring washer. The clamping height between the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 can be adjusted to a certain extent, which can be used for components with different frame thicknesses. Finally, just tighten the fixing bolt 6.

[0030] refer to Figures 1-3 In one implementation, the upper horizontal fixing plate 1 is provided with an upper fixing plate arc 7, with the upper fixing plate arc 7 located away from the vertical snow baffle 3. The lower horizontal fixing plate 2 is provided with an outwardly protruding groove 4 for limiting the component frame 11 at the end away from the vertical snow baffle 3. By setting the upper fixing plate arc 7 to cooperate with the top surface of the component frame 11, and by setting the outwardly protruding groove 4 to limit the component frame 11 with the bottom surface of the component frame 11, the component frame 11 is locked and the support strength is guaranteed.

[0031] refer to Figures 1-3 In one embodiment, the upper horizontal fixing plate 1 and the component frame 11 are provided with upper fixing plate corrugations 10, and the lower horizontal fixing plate 2 and the component frame 11 are provided with lower fixing plate corrugations 9. By providing upper fixing plate corrugations 10 and lower fixing plate corrugations 9, the friction between the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 and the component frame 11 can be increased, further enhancing the firmness of the snow-blocking clamp and the component frame 11.

[0032] refer to Figures 1-3 In one embodiment, the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 are arranged in parallel, and the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 are connected by an inclined plate. The upper horizontal fixing plate 1, the lower horizontal fixing plate 2, the inclined plate and the vertical snow baffle 3 are integrally formed structures, which are easy to process.

[0033] refer to Figures 1-3 As one implementation method, the vertical snow shield 3 is set perpendicular to the upper horizontal fixing plate 1, which can improve the snow blocking effect.

[0034] refer to Figures 1-3As one implementation, the protruding slot 4 extends toward the upper transverse fixing plate 1. By setting the protruding slot 4, the fixing and anti-slip performance of the upper transverse fixing plate 1 and the lower transverse fixing plate 2 to the component frame 11 can be further improved when the upper transverse fixing plate 1 and the lower transverse fixing plate 2 are installed with the component frame 11.

[0035] refer to Figures 1-3 In one embodiment, the component frame 11 includes a first mating surface that cooperates with the upper horizontal fixing plate 1, and a second mating surface that fits with the lower horizontal fixing plate 2 and abuts against the outward protruding slot 4. The first mating surface and the second mating surface are connected by a vertical partition. The component frame 11 is an integrally formed structure. By setting the component frame 11, the photovoltaic panel can be fixed without directly clamping the photovoltaic panel, thus avoiding damage to the photovoltaic panel.

[0036] refer to Figures 1-3 As one implementation method, the first bonding surface is provided with an arc-shaped surface that fits with the upper fixing plate's curved arc 7. By setting the upper fixing plate's curved arc 7 to cooperate with the arc-shaped surface, the contact between the upper horizontal fixing plate 1 and the component frame 11 can be made more closely fitted, while increasing the anti-slip performance between the upper horizontal fixing plate 1 and the component frame 11, and further improving the firmness between the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 and the component frame 11.

[0037] refer to Figures 1-3 As one implementation method, the first bonding surface is inclined toward the second bonding surface, which can further ensure the clamping effect on the component frame 11.

[0038] During on-site installation, the fixing bolts 6 are first loosened to allow easy adjustment of the height between the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 of the snow-blocking clamp, which are then attached to the component frame 11. Next, the protruding groove 4 at one end of the lower horizontal fixing plate 2 of the snow-blocking clamp is engaged with the second contact surface at the bottom of the component frame 11. Simultaneously, the curved arc 7 of the upper fixing plate 1 of the upper horizontal fixing plate of the snow-blocking clamp is aligned with the curved surface of the component frame 11. Finally, the fixing bolts 6 are tightened with a wrench to ensure that the tightening force between the upper horizontal fixing plate 1 and the lower horizontal fixing plate 2 and the component frame 11 meets the design requirements. Thus, a complete snow-blocking clamp and component installation is completed.

[0039] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
