Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of photovoltaic frame assembly clamps, and in particular to an assembly clamp for reinforcing the frame of a photovoltaic module. Background Technology
[0002] The installation of rooftop photovoltaic (PV) modules has become an important practice in promoting green energy. However, the diversity of roof structures, such as ceramic tiles, asphalt shingles, and metal roofs, presents challenges for PV system installation. Especially in large-scale PV projects, a single project often encompasses multiple roof types, which undoubtedly increases the complexity of the installation work.
[0003] Current photovoltaic (PV) module installation and fixing technologies primarily rely on traditional fixing methods. However, these methods reveal significant shortcomings under harsh weather conditions such as high wind pressure and typhoons. Due to the lack of reinforcement in the frame cross-section, the frames of large-sized modules lack stability under strong wind loads, easily leading to deformation, loosening, or even detachment. This severely impacts the safety and reliability of the PV system. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a combined clamp for reinforcing the frame of photovoltaic modules with strong wind resistance and stable connection.
[0005] The technical solution adopted by this utility model is as follows: This utility model includes a purlin for supporting the photovoltaic frame; a reinforcing beam fixedly connected to one side of the photovoltaic frame; a pressing member, one end of which forms a sliding groove that cooperates with the reinforcing beam, and the other end of which forms a limiting groove; and a locking member, the upper part of which cooperates with the limiting groove, and the lower part of which is locked and fixed to the purlin.
[0006] Furthermore, the opening side of the limiting groove faces upward, and a support foot that fits snugly against the purlin is formed on one side of the limiting groove. A stress-relieving hole is formed between the limiting groove and the sliding groove, and a reinforcing rib for enhancing rigidity is provided in the stress-relieving hole.
[0007] Furthermore, the sliding groove is a "T" shaped groove.
[0008] Furthermore, the locking component includes a U-bolt, a locking plate, and two connecting nuts. The middle part of the U-bolt is limited and engaged with the limiting groove. Both ends of the U-bolt pass through the purlin. Both ends of the locking plate have openings that engage with the ends of the U-bolt. Each connecting nut is threadedly engaged with the corresponding U-bolt. The locking plate is tightly fitted to the lower surface of the purlin.
[0009] Furthermore, the locking plate is a U-shaped groove.
[0010] Furthermore, grooves are formed on both sides of the reinforcing beam, and the grooves are guided and engaged with the sliding groove. Several mounting holes are formed on the upper surface of the reinforcing beam to be fixedly connected to the photovoltaic frame.
[0011] The beneficial effects of this utility model are as follows: This utility model uses a reinforcing beam connected to a pressure bracket via a sliding groove. Under the action of external forces such as high wind pressure, the load borne by the photovoltaic frame is first transferred to the reinforcing beam. The reinforcing beam, through its connection with the pressure bracket, transfers the load to the purlins, and then to the entire photovoltaic support structure. The reinforcing beam significantly improves the strength and rigidity of the photovoltaic frame, effectively resisting the action of external forces such as wind loads, avoiding problems such as deformation and loosening, thus forming a stable fixed support system.

[0018] like Figures 1 to 4 As shown, in this embodiment, the present invention includes a purlin 2 for supporting the photovoltaic frame 1; a reinforcing beam 3 fixedly connected to one side of the photovoltaic frame 1; a pressing member 4, one end of which forms a sliding groove 41 that cooperates with the reinforcing beam 3, and the other end of which forms a limiting groove 42; and a locking member 5, the upper part of which cooperates with the limiting groove 42, and the lower part of which is locked and fixed to the purlin 2.
[0019] Specifically, the reinforcing beam 3 is made of 6005-T5 aluminum alloy with an oxide film thickness reaching the AA15 standard. It is fixed to the photovoltaic frame 1 by bolts and connected by the sliding groove 41 of the pressure piece 4. The grooves 31 on both sides of the reinforcing beam 3 cooperate with the sliding groove 41, so that the pressure piece 4 can move back and forth along the direction of the reinforcing beam 3, which facilitates the installation and adjustment of the reinforcing beam 3. It can also form an effective force transmission between the reinforcing beam 3 and the pressure piece 4 when the photovoltaic frame 1 is subjected to external force, so as to jointly bear the load.
[0020] The clamping component 4 serves as a connecting structure, with one end connected to the reinforcing beam 3 and the other end clamped and fixed to the purlin 2 in conjunction with the locking component 5. It is used to transmit the external force received by the photovoltaic frame 1, allowing the external force to be transmitted to the purlin 2 along the locking component 5.
[0021] The reinforcing beam 3 is connected to the clamping component 4 via a sliding groove. Under the action of external forces such as high wind pressure, the load borne by the photovoltaic frame 1 is first transferred to the reinforcing beam 3. The reinforcing beam 3, through its connection with the clamping component 4, transfers the load to the purlin 2, and then to the entire photovoltaic support structure. The reinforcement effect of the reinforcing beam 3 significantly improves the strength and stiffness of the photovoltaic frame 1, effectively resisting the action of external forces such as wind loads, avoiding problems such as deformation and loosening, thus forming a stable fixed support system.
[0022] like Figure 4 As shown, in this embodiment, the opening side of the limiting groove 42 faces upward, and a support leg 43 is formed on one side of the limiting groove 42 to fit snugly with the purlin 2. A stress relief hole 44 is formed between the limiting groove 42 and the sliding groove 41, and a reinforcing rib 45 for enhancing rigidity is provided in the stress relief hole 44.
[0023] Specifically, the limiting groove 42 has a circular structure and is used for the middle section connection of the U-bolt to improve the connection stability. The stress relief hole 44 is set between the limiting groove 42 and the sliding groove 41. The stress relief hole 44 is located close to the sliding groove 41, so that the end of the pressure piece 4 close to the sliding groove 41 has a certain amount of force displacement. The reinforcing rib 45 set in the stress relief hole 44 improves the overall bending strength of the pressure piece 4. At the same time, the stress relief hole 44 reduces the amount of material used and effectively reduces the production cost.
[0024] In this embodiment, the sliding groove 41 is a "T" shaped groove.
[0025] like Figure 3As shown, in this embodiment, the locking component 5 includes a U-bolt, a locking plate 52, and two connecting nuts 53. The middle part of the U-bolt is limited and engaged with the limiting groove 42. Both ends of the U-bolt pass through the purlin 2. The two ends of the locking plate 52 are formed with openings that engage with the ends of the U-bolt. Each connecting nut 53 is threadedly engaged with the corresponding U-bolt. The locking plate 52 is tightly fitted to the lower surface of the purlin 2.
[0026] Specifically, the U-bolt is made of stainless steel. One end of the clamping piece 4 is pressed and fixed onto the purlin 2 by the connecting nut 53. The locking plate 52 is a U-shaped groove used to connect the two ends of the U-bolt, so that the U-bolt and the purlin 2 are locked and fixed.
[0027] In this embodiment, the locking plate 52 is a U-shaped groove.
[0028] like Figure 5 As shown, in this embodiment, grooves 31 are formed on both sides of the reinforcing beam 3, and the grooves 31 are guided and engaged with the sliding groove 41. A plurality of mounting holes are formed on the upper surface of the reinforcing beam 3 to be fixedly connected to the photovoltaic frame 1.
[0029] The working principle of this utility model:
[0030] The reinforcing beam 3 is connected to the pressure plate 4 through a groove. Under the action of external forces such as high wind pressure, the load borne by the photovoltaic frame 1 is first transferred to the reinforcing beam 3. The reinforcing beam 3 transfers the load to the purlin 2 through the connection with the pressure plate 4, and then to the entire photovoltaic support structure.
[0031] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
