Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic fixing equipment technology, and in particular relates to a fixing device for fixing photovoltaic modules. Background Technology

[0002] Currently, metal roofs are commonly used as the supporting surface for photovoltaic modules in building-integrated photovoltaic (BIPV) systems. M-shaped water channels are a common roof system component, and their fixing method directly affects the safety and reliability of the entire photovoltaic system. Existing technology typically uses U-bolt clamps to tighten the M-shaped water channel onto the purlins, with pressure blocks pressed against the top of the purlins to compress the two wings on the sides, thus fixing the M-shaped water channel to the roof purlins. While this method has some application, it has several inherent drawbacks: First, U-bolts are expensive to manufacture, typically costing more than 50 times more than self-tapping screws, significantly increasing overall installation costs and hindering large-scale application. Second, U-bolts rely on the shape of the purlin for clamping and fixing, making them unsuitable for irregular cross-sections like Z-shaped steel purlins. They can only be used with C-shaped purlins or a limited range of support structures, restricting their application in diverse building structures. Third, their installation process is complex, requiring additional washers, nuts, and other accessories, resulting in low construction efficiency, high labor intensity, and increased installation difficulty and safety hazards, especially at heights. More seriously, this fixing method relies on the friction between the U-bolt and the pressure block, as well as the friction between the pressure block and the trough's flanges, to tighten the trough. If the U-bolt is not fully tightened, the pressure block is not properly pressed in place, or vibration occurs during use causing it to loosen, the trough flanges may slip or even detach entirely, leading to serious safety accidents.

[0016] 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.

[0017] Reference Figures 1-3 This utility model provides a fixing device for fixing photovoltaic modules, including a purlin 1, a water tank 2 provided on the purlin 1, and further including: Two sets of clamping plates 6, the bottom of the clamping plates 6 are fixedly connected to the purlin 1 by the first locking component, and the tops of the two clamping plates 6 are respectively pressed against the top sides of the water tank 2. The second locking component is disposed on both sides of the bottom of the water tank 2. The second locking component is used to directly fix the water tank 2 to the purlin 1. The connecting plate 3 is fixedly connected to the top of the water tank 2 by a third locking component. Bolts 4 are detachably connected to the connecting plate 3. An anchoring component is installed through the photovoltaic module. The bolts 4 fix the photovoltaic module to the connecting plate 3 through the anchoring component.

[0018] The main function of the first locking component is to directly fix the clamping plate 6 to the top of the purlin 1; the main function of the clamping plate 6 is to press the water tank 2 onto the purlin 1; the main function of the second locking component is to directly fix the water tank 2 onto the purlin 1, improving the firmness of the water tank 2; the main function of the anchoring component is to facilitate the connection of the photovoltaic module and the connecting plate by the bolt 4, ultimately achieving the fixation of the photovoltaic module. Overall, this utility model, by setting a clamping plate that can be directly locked onto the top of the purlin to press the water tank onto the purlin, not only serves to fix the purlin, but also, because it does not require structures such as U-bolts, can be applied to purlins of various structures. Since the two wings of the water tank no longer need to be squeezed by pressure blocks, they can be directly fixed to the purlin by the second locking component, improving the connection stability of the water tank and effectively preventing the water tank from sliding. The solution of this utility model has the characteristics of simple and reliable structure, low cost, and convenient installation.

[0019] Further optimization of the scheme: the clamping plate 6 includes an L-shaped connecting plate 63. The bottom edge of the L-shaped connecting plate 63 is vertically fixedly connected to an abutment plate 61, which abuts against the purlin 1. The top of the L-shaped connecting plate 63 is fixedly connected to an arc-shaped bent plate 62, which faces away from the abutment plate 61 and abuts against the top of the water tank 2. The bottom of the L-shaped connecting plate 63 is provided with several through holes 64, and the first locking component is correspondingly set with several through holes 64.

[0020] In a further optimized design, the first locking component includes several second self-tapping screws 7, which pass through several through holes 64 and are screwed onto the top wall of the purlin 1.

[0021] like Figure 2 and Figure 3As shown, by setting abutment plates 61 and arc-shaped bending plates 62 on both sides of the clamping plate 6, during installation, the arc-shaped bending plates 62 of the clamping plate 6 are pressed against the top of the water tank 2, while the abutment plates 61 are abutted against the top of the purlin 1. Then, the second self-tapping screw 7 is passed through the through hole 64 and directly threaded onto the purlin 1. The second self-tapping screw is used to press down the L-shaped connecting plate 63 to fix the clamping plate 6 between the purlin 1 and the water tank 2, forming a clamped state.

[0022] Further optimization of the scheme: the second locking component includes several third self-tapping screws 8. The bottom of the two opposite side walls of the water tank 2 is fixedly connected to a pressure plate. Several third self-tapping screws 8 pass through the pressure plate and fix the pressure plate to the top wall of the purlin 1.

[0023] like Figure 2 As shown, due to the structure of the abutment plate 61, there is a gap between the L-shaped connecting plate 63 and the side wall of the water tank 2, which can effectively avoid positional interference and facilitate the third self-tapping screw 8 to pass through the pressure plates on both sides of the water tank 2, that is, the two wings of the water tank 2 and fix them to the top of the purlin 1, further fixing the water tank 2.

[0024] Further optimization of the scheme: the third locking component includes several first self-tapping screws 5, and connecting plates are fixedly connected to both ends of the connecting plate 3. The connecting plates are attached to the two opposite side walls of the water tank 2. Several first self-tapping screws 5 pass through the connecting plates and fix the connecting plates to the side walls of the water tank 2.

[0025] like Figure 1 and Figure 2 As shown, the first self-tapping screw 5 passes through both sides of the connecting plate 3 and is fixed to the side wall of the water tank 2, thereby realizing the connection between the connecting plate 3 and the water tank 2.

[0026] The scheme is further optimized. The anchoring component includes a snap-fit ​​seat 9 and a through hole opened on the photovoltaic module. The top of the outer wall of the snap-fit ​​seat 9 is provided with an annular groove. The inner wall of the through hole is snapped into the annular groove. The bottom of the snap-fit ​​seat 9 abuts against the connecting plate 3. A through groove is vertically opened in the middle of the snap-fit ​​seat 9. The threaded end of the bolt 4 passes through the through groove and is fixedly connected to the connecting plate 3. The head of the bolt 4 is fixedly connected to the top of the snap-fit ​​seat 9 through a pressing member.

[0027] Further optimization of the scheme: the extrusion part includes a pressure cap 10, the top edge of the pressure cap 10 is fixedly connected to a pressure lip, the pressure cap 10 is located in the through groove, and the pressure lip abuts against the top of the snap-fit ​​seat 9, the bolt 4 passes through the pressure cap 10 and the head of the bolt 4 abuts against the top of the pressure cap 10.

[0028] like Figure 2As shown, the top of the snap-fit ​​base 9 has an annular groove. The snap-fit ​​base 9 is snapped into the photovoltaic module through the annular groove. During installation, after the photovoltaic module is placed on the water tank 2, the pressure cap 10 is inserted into the through groove of the snap-fit ​​base 9. The bolt 4 is then tightened onto the connecting plate 3 through the pressure cap 10 to complete the fixing of the photovoltaic module.

[0029] In a further optimized design, a sealing cap 11 is detachably connected to the top of the pressure cap 10.

[0030] like Figure 2 As shown, a conventional locking block and slot structure is provided between the sealing cap 11 and the pressure cap 10. By locking the sealing cap 11 onto the top of the pressure cap 10, the corrosion of the bolt 4 by rainwater and other factors can be avoided.
