Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation technology, specifically a wind-resistant photovoltaic module clamping block. Background Technology

[0002] With the increasing global demand for renewable energy, photovoltaic (PV) modules play an important role in the current energy transition, promoting global environmental protection and the development of green energy. In coastal areas with high wind speeds, wind may exert significant uplift force on PV modules. Therefore, when installing PV modules in coastal areas, wind factors need to be considered during the design and installation process to ensure the stability of the structure.

[0003] The existing fixing blocks for photovoltaic modules, which serve as intermediate components connecting the photovoltaic modules and the profiles, can slide and adjust their position on the profiles. In environments with high wind speeds, this can easily cause the photovoltaic modules to sway back and forth relative to the profiles, potentially leading to them falling off. Furthermore, if the connection between the two parts of the fixing block that connect the photovoltaic modules and the profiles is not stable, it can increase the risk of the photovoltaic modules being lifted off their own, which can not only damage the photovoltaic modules but also pose a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a wind-resistant photovoltaic module clamping block to solve the problems mentioned in the background art. The existing clamping blocks for fixing photovoltaic modules, which are intermediate components connecting photovoltaic modules and profiles, can slide and adjust their position on the profile. In environments with high wind speeds, these clamping blocks can easily cause the photovoltaic modules to sway back and forth relative to the profiles, leading to their detachment. At the same time, if the connection stability between the two parts of the clamping block connecting the photovoltaic module and the profile is poor, it will increase the risk of the photovoltaic module being lifted, which will not only damage the photovoltaic module but also pose a safety hazard.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-resistant photovoltaic module clamping block, comprising a profile, a middle clamping block assembly, and a side clamping block assembly. The profile is used to fix the photovoltaic module by installing the middle clamping block assembly and the side clamping block assembly. The module also includes a profile clamping block connecting assembly and an outer ring connecting assembly. The profile clamping block connecting assembly is connected above the profile. The profile clamping block connecting assembly and the profile have two states: sliding connection and fixed connection. The middle clamping block assembly and the side clamping block assembly are both fixedly connected above the profile clamping block connecting assembly. The middle clamping block assembly and the side clamping block assembly are both connected to the outer ring connecting assembly to form a ring structure. The profile passes through the inside of the ring and is limited in position.

[0006] Preferably, the profile surface is grooved to provide a track, the profile pressure block connecting assembly includes a movable block, the movable block is embedded inside the track, the movable block is slidably connected to the profile, a first screw hole is provided in the middle of the movable block from top to bottom, and the middle pressure block assembly and the side pressure block assembly are both threadedly connected to the first screw hole of the movable block by vertical bolts.

[0007] Preferably, the profile pressing block connecting assembly further includes a bending piece and a positioning member. One end of the bending piece is fixedly connected to the top of the movable block, and the other end is bent at a position parallel to the side facade of the profile. The positioning member is movably connected to the bending piece. When the profile pressing block connecting assembly and the profile are in a relatively fixed state, the positioning member abuts against the side facade of the profile.

[0008] Preferably, the positioning element includes a horizontal bolt, a pressing block, and a washer. The bent piece has a second threaded hole, the horizontal bolt is threaded to the second threaded hole of the bent piece, the pressing block is provided at the end of the horizontal bolt screw, and the washer is provided on the surface of the pressing block.

[0009] Preferably, the middle pressure block assembly includes a first horizontal plate and a first recessed part, with the first recessed part connected below the opening position of the first horizontal plate. The side pressure block assembly includes a second horizontal plate and a second recessed part, with the second recessed part connected below the notch position of the second horizontal plate. The bottom of the first recessed part and the second recessed part have slots, and the vertical bolt passes through the slots from top to bottom.

[0010] Preferably, the first horizontal plate has first external connecting holes on both sides of the first recessed part perpendicular to the longitudinal direction of the profile, and the second horizontal plate has second external connecting holes on both sides of the second recessed part perpendicular to the longitudinal direction of the profile. The outer ring connecting assembly includes a limiting plate, a U-bolt, and a nut. The U-bolt connecting the middle pressure block assembly has its end sleeved over the profile from bottom to top, passes through the first external connecting hole of the first horizontal plate, and connects to the nut. The U-bolt connecting the side pressure block assembly has its end sleeved over the profile from bottom to top, passes through the second external connecting hole of the second horizontal plate, and connects to the nut. The limiting plate is fitted with connecting U-bolts located at the bottom of the profile.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a profile pressing block connecting component to fix the positions of the middle pressing block component and the side pressing block component. The fixed connection between the component and the profile makes it difficult for the middle pressing block component and the side pressing block component to shift away from the profile. Moreover, the positions of multiple middle pressing block components and side pressing block components are fixed, and the distance between them is not easy to change. Therefore, in windy weather, even if the photovoltaic module is affected by the wind, it can reduce the back-and-forth swaying of the photovoltaic module in the profile track direction. It can also prevent the photovoltaic module from detaching due to the increased distance between the middle pressing block component and the side pressing block component that limits the same photovoltaic module. This improves the stability of the photovoltaic module, protects the photovoltaic module and reduces safety hazards.

[0013] 2. By setting the outer ring connecting components, this utility model makes the connection between the profile and the middle pressure block assembly and the side pressure block assembly more stable, and can further enhance the stability of the connection between the middle pressure block assembly and the side pressure block assembly and the profile pressure block connecting assembly, as well as the connection between the profile and the profile pressure block connecting assembly. On the other hand, the U-bolt can also restrict the profile from shifting and separating from the middle pressure block assembly and the side pressure block assembly in the lateral direction. Its unique ring-shaped wrapping structure generates a strong radial clamping force through the U-bolt, making it hug the profile like a hoop, which can effectively improve the wind resistance, connection strength and stability of the entire support system, and reduce the core risk of photovoltaic modules being lifted.

[0024] 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.

[0025] One embodiment of this utility model provides: a wind-resistant photovoltaic module clamping block, such as... Figure 1 and Figure 2 As shown, it includes profile 1, middle pressure block assembly 2, side pressure block assembly 3, profile pressure block connecting assembly 4, vertical bolt 5, and outer ring connecting assembly 6.

[0026] like Figures 1 to 4 As shown, the profile 1 fixes the photovoltaic module 7 by installing the middle pressure block assembly 2 and the edge pressure block assembly 3. The middle pressure block assembly 2 is installed between the edges of two photovoltaic modules 7, and the edge pressure block assembly 3 is installed on one side edge of a single photovoltaic module 7 located at the edge position. The side of the photovoltaic module 7 is limited by the middle pressure block assembly 2 and the edge pressure block assembly 3, and the bottom of the photovoltaic module 7 is supported on the profile 1.

[0027] Both the middle pressure block assembly 2 and the side pressure block assembly 3, which are required to be fixed in position for the photovoltaic module 7, are connected to the profile 1 via the profile pressure block connecting assembly 4. Before installing and fixing the middle pressure block assembly 2 and the side pressure block assembly 3 of the photovoltaic module 7 on the profile 1, the connecting component profile pressure block connecting assembly 4 is first installed onto the profile 1.

[0028] like Figure 5As shown, the profile pressing block connecting assembly 4 is connected above the profile 1. The profile pressing block connecting assembly 4 includes a movable block 41. A track 11 is grooved on the surface of the profile 1, and the movable block 41 is embedded in the track 11, and the movable block 41 is slidably connected to the profile 1. The movable block 41 embedded in the track 11 can move along the track 11. According to the size and arrangement of the photovoltaic module 7, the positions of the middle pressing block assembly 2 and the side pressing block assembly 3 to be installed can be determined. The movable block 41 is moved to this position. The connection method between the movable block 41 and the track 11 makes it easy to gradually adjust the position of the components connecting the middle pressing block assembly 2 and the side pressing block assembly 3 according to the process of determining the position of the photovoltaic module 7 until the precise position is determined, ensuring that the spacing between the photovoltaic modules 7 is uniform, the edges are aligned, and adapting to photovoltaic modules 7 of different sizes and specifications.

[0029] There are two states between the profile pressing block connecting assembly 4 and the profile 1: sliding connection and fixed connection. During the process of determining the installation position of the middle pressing block assembly 2 and the side pressing block assembly 3, the profile pressing block connecting assembly 4 is slidably adjusted. When the installation position of the middle pressing block assembly 2 and the side pressing block assembly 3 is determined, the profile pressing block connecting assembly 4 and the profile 1 are changed to a relatively fixed connection method. The profile pressing block connecting assembly 4 also includes a bending piece 42 and a positioning member 43. One end of the bending piece 42 is fixedly connected to the top of the movable block 41, and the other end is bent at a position parallel to the side facade of the profile 1. The positioning member 43 is movably connected to the bending piece 42. The positioning member 43 includes a horizontal bolt 431, a pressing block 432, and a washer 433. The bending piece 42 has a second threaded hole 421. The horizontal bolt 431 is threaded to the second threaded hole 421 of the bending piece 42. The pressing block 432 is provided at the end of the horizontal bolt 431. The washer 433 is provided on the surface of the pressing block 432. When the profile pressing block connecting assembly 4 and the profile 1 are adjusted to a relatively fixed state, the horizontal bolt 431 is tightened so that the pressing block 432 of the positioning member 43 abuts against the side facade of the profile 1. The flexible material washer 433 increases the friction between the pressing block 432 and the profile 1, improving the stability of the profile pressing block connecting assembly 4 when it is fixed to the profile 1. As a profile pressing block connecting component 4 that can fix the middle pressure block component 2 and the side pressure block component 3, its fixed connection with the profile 1 makes it difficult for the middle pressure block component 2 and the side pressure block component 3 to shift from the profile 1. Moreover, the positions of multiple middle pressure block components 2 and side pressure block components 3 are fixed, and the distance between them is not easy to change. Therefore, in windy weather, even if the photovoltaic module 7 is affected by the wind, it can reduce the back-and-forth swaying of the photovoltaic module 7 in the direction of the track 11 of the profile 1. It can also prevent the phenomenon that the distance between the middle pressure block component 2 and the side pressure block component 3 that limit the same photovoltaic module 7 increases, causing the photovoltaic module 7 to detach. This improves the stability of the photovoltaic module 7, protects the photovoltaic module 7, and reduces safety hazards.

[0030] like Figure 6 and Figure 7As shown, the middle pressure block assembly 2 includes a first horizontal plate 21 and a first recessed member 22. The first recessed member 22 is connected below the opening position of the first horizontal plate 21. The side pressure block assembly 3 includes a second horizontal plate 31, a second recessed member 32, and a vertical plate 33. The second recessed member 32 is connected below the notch position of the second horizontal plate 31. The bottom of the first recessed member 22 and the second recessed member 32 have slots. The vertical plate 33 is connected below the second recessed member 32 on the side of the notch position of the second horizontal plate 31. The two sides of the first horizontal plate 21 extending beyond the first recessed member 22 press on two photovoltaic modules 7 respectively; the edges of the second horizontal plate 31 extending beyond the second recessed member 32 press on a single photovoltaic module 7 on one side. Since the edge pressure block assembly 3 presses the edge of the photovoltaic module 7 on one side, the setting of the vertical plate 33 can support its bottom on the profile 1, improve the balance and stability of the edge pressure block assembly 3 in limiting the photovoltaic module 7, and the height of the edge pressure block assembly 3 is consistent with the height of the photovoltaic module 7 that is tightly attached to the bottom of the profile 1.

[0031] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, both the middle pressure block assembly 2 and the side pressure block assembly 3 are fixedly connected to the movable block 41 of the profile pressure block connecting assembly 4 by vertical bolts 5. A first screw hole 411 is provided in the middle of the movable block 41 from top to bottom. The vertical bolt 5 passes through the slots at the bottom of the first recessed part 22 and the second recessed part 32 from top to bottom, and is threaded into the first screw hole 411 of the movable block 41. After the middle pressure block assembly 2 and the side pressure block assembly 3 are respectively connected to the corresponding movable blocks 41, and the photovoltaic modules 7 are arranged in the correct positions, the vertical bolts 5 are tightened. A stable mechanical connection is formed between the photovoltaic modules 7 and the profile 1, which is the most direct guarantee against wind uplift forces.

[0032] Both the middle pressure block assembly 2 and the side pressure block assembly 3 are connected to the outer ring connecting assembly 6 to form a ring structure, with the profile 1 passing through the inside of the ring and being limited. The first horizontal plate 21 has first external connecting holes 211 on both sides of the first recessed part 22 perpendicular to the longitudinal direction of the profile 1, and the second horizontal plate 31 has second external connecting holes 311 on both sides of the second recessed part 32 perpendicular to the longitudinal direction of the profile 1. The outer ring connecting assembly 6 includes a limiting plate 61, a U-bolt 62, and a nut 63. The U-bolt 62 connecting the middle pressure block assembly 2 has its end sleeved from bottom to top through the profile 1, through the first external connecting hole 211 of the first horizontal plate 21, and connected to the nut 63. The U-bolt 62 connecting the side pressure block assembly 3 has its end sleeved from bottom to top through the profile 1, through the second external connecting hole 311 of the second horizontal plate 31, and connected to the nut 63. The limiting plate 61 is fitted with the connecting U-bolt 62 and is located at the bottom of the profile 1. Adding an outer ring connecting component 6 at the installation locations of the middle pressure block assembly 2 and the side pressure block assembly 3, and tightening the nut 63 at the end of the U-bolt 62, on the one hand, makes the connection between the profile 1 and the middle pressure block assembly 2 and the side pressure block assembly 3 more stable, and further strengthens the connection between the middle pressure block assembly 2 and the side pressure block assembly 3 and the profile pressure block connecting component 4, as well as the connection between the profile 1 and the profile pressure block connecting component 4. On the other hand, the U-bolt 62 can also restrict the profile 1 from shifting and separating from the middle pressure block assembly 2 and the side pressure block assembly 3 in the lateral direction. Its unique ring-shaped wrapping structure generates a strong radial clamping force through the U-bolt 62, making it hug the profile 1 like a hoop, which can effectively improve the wind resistance, connection strength and stability of the entire support system, and reduce the core risk of the photovoltaic module 7 being lifted.

[0033] Two sets of positioning components 43 are provided, symmetrical about the bending piece 42. On the one hand, this can increase the stability of the fixed connection, and on the other hand, it can prevent interference with the U-bolt 62 located in the middle.

[0034] Based on the vertical bolt 5 fixing the middle pressure block assembly 2 and the side pressure block assembly 3, an outer ring connecting assembly 6 is added. This not only further increases the stability, but also changes the single-hole single-nail connection method of the vertical bolt 5 to a multi-hole multi-nail connection method. The middle pressure block assembly 2 and the side pressure block assembly 3 are less likely to have angular displacement relative to the profile 1, and the positioning of the photovoltaic module 7 by the middle pressure block assembly 2 and the side pressure block assembly 3 can be more accurate.

[0035] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics in the solutions has not been described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
