Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and specifically to a photovoltaic clamp for color steel plate building roofs. Background Technology

[0002] With the global energy structure shifting towards cleaner energy, the photovoltaic industry has developed rapidly. Distributed photovoltaic power generation systems, due to their strong adaptability, are increasingly widely used in various corrugated steel roofing scenarios, such as industrial plants, warehouses, and residential buildings. In this system, the photovoltaic support frame, as a core structural component, connects the corrugated steel roof and the photovoltaic modules, playing a crucial role in supporting and fixing the photovoltaic modules. It is necessary to achieve a parallel or inclined connection between the photovoltaic modules and the roof, and its stability directly determines the long-term effective operation capability and power generation efficiency of the photovoltaic power generation system.

[0003] Currently, the mainstream connection methods between color steel roofing and photovoltaic brackets include angle-lock type, standing seam type, trapezoidal bolt fixing, and strong adhesive. Among these, to enhance the stability of the connection, the industry generally adopts the "penetration connection" solution: holes are drilled on the top and side surfaces of the bracket clamps and the color steel plate, and bolts are used to penetrate the color steel plate and fasten it to the roof purlins. However, this solution has significant technical drawbacks: Firstly, drilling directly damages the structural integrity of the color steel plate. Over long-term use, rainwater can easily seep into the roof through the drilled holes, causing roof leaks, affecting the normal performance of the building, and leading to corrosion and damage to the brackets, significantly shortening the service life of the roof and brackets, and increasing later maintenance costs. Secondly, the penetration connection requires extremely high precision in the relative position of the bolt holes. If drilling deviation occurs during construction, it can easily lead to insufficient installation accuracy, requiring repeated inspection, correction, or even re-drilling, severely reducing construction efficiency. Furthermore, custom processing of bolt holes is required when adapting to different corrugated color steel plates, further increasing application costs.

[0004] In summary, existing photovoltaic support solutions for corrugated steel roofs suffer from problems such as damaging the roof structure, easy leakage, low construction efficiency, and high cost. These issues make it difficult to meet the requirements of distributed photovoltaic systems for ease of installation, structural stability, and economy. A better connection technology solution is urgently needed to address these pain points. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic clamp for color steel plate building roofs to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution: A photovoltaic clamp for a color steel plate building roof is installed on the color steel plate and supports the photovoltaic modules. It includes two sets of corresponding guide rail assemblies, and the guide rail assemblies are fixed above the color steel plate by steel rib clamp assemblies. Both sets of guide rail assemblies are equipped with a low-position lower pressure block assembly; A high-position lower pressure block assembly is provided on the lower-position lower pressure block assembly; One end of the photovoltaic module is mounted on a high lower pressure block assembly on one of the guide rail assemblies via a pressing mechanism, and the other end is mounted on a low lower pressure block assembly on another guide rail assembly.

[0008] Furthermore, the guide rail assembly includes a profile guide rail and a first rectangular boss; The profile guide rail is divided into upper and lower guide rail sections, and each of the two guide rail sections is provided with a limiting groove; the two side walls of the profile guide rail are provided with a locking groove. The bottom panel of the L-shaped mounting section of the inner positioning corner piece is provided with a positioning slot hole, and the side panel of the L-shaped mounting section of the inner positioning corner piece is provided with a limit key. The first rectangular protrusion is provided with a first limiting protrusion, and the first rectangular protrusion is provided with a first limiting platform on both sides of the first limiting protrusion; A first threaded countersunk hole is provided at the position of the first limiting boss, and a second screw is screwed into the first threaded countersunk hole. The first rectangular boss is engaged in the guide rail section below the profile guide rail, the first limiting platform is abutted against the limiting groove, and the second screw passes through the positioning slot hole opened on the profile guide rail and the inner positioning corner piece in sequence, and is screwed with the second nut. The limiting key on the inner positioning corner piece engages with the slot of the profile guide rail.

[0009] Furthermore, the lower pressure block assembly includes a lower pressure code and a second rectangular boss; The low-position pressure code includes a pressure block installation section, a connecting section, and a pressure code installation section in sequence; The connecting section has a limiting slot and a positioning screw hole. The limiting slot on the connecting section is fitted with the guide rail flat section above the profile guide rail. The second rectangular protrusion is provided with a second limiting protrusion, and the second rectangular protrusion is provided with a second limiting platform on both sides of the second limiting protrusion; A second threaded countersunk hole is provided at the position of the second limiting boss, and a fourth screw is screwed into the second threaded countersunk hole; The second rectangular boss is engaged in the guide rail section above the profile guide rail, the second limiting platform is abutted against the limiting groove, and the fourth screw passes through the positioning screw holes of the profile guide rail and the connecting section in sequence, and is screwed with the fourth nut. The pressing block installation section is provided with a pressing block installation groove, and a high-position lower pressing block assembly is rotatably installed in the pressing block installation groove; The pressing code installation section has a pressing code installation slot, and an integral pressing code is rotatably installed in the pressing code installation slot.

[0010] Furthermore, the high-position lower pressure block assembly includes a positioning column, one end of which is disposed in the pressure block mounting groove and is rotatable; The positioning column is provided with several L-shaped limiting grooves arranged along its column body direction; The clamping mechanism includes an edge clamping block assembly, which includes an edge clamping code, and each of the positioning columns is provided with one edge clamping code.

[0011] Furthermore, the clamping mechanism also includes a central clamping block assembly, which includes a central clamping code, and each of the positioning columns is provided with a side clamping code or a central clamping code; The central pressure code includes a second upright U-shaped slot and two second horizontal U-shaped slots respectively connected to the two side walls of the second upright U-shaped slot; The second upright U-shaped slot is inserted into the L-shaped limiting slot, the inclined side end of the photovoltaic module is inserted into the first or second inclined U-shaped slot, and the inclined bottom end of the photovoltaic module is engaged in the pressing U-shaped slot.

[0012] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows: Most existing technologies employ "penetrating connections," requiring drilling into the top and sides of the corrugated steel sheet, directly compromising the structural integrity of the steel sheet. Over time, this leads to roof leaks due to rainwater seepage, and also causes corrosion and damage to the support structure, increasing future maintenance costs. This invention achieves a non-penetrating connection through the mechanical interlocking structure of the steel frame clamp assembly (the inner clamping section of the inner positioning corner piece fits against the inner surface of the corrugated steel sheet, and the outer clamping section of the outer positioning corner piece abuts against the bottom of the corrugated steel sheet, combined with the rotational engagement of the limiting opening ring and the limiting shaft, and the fixing with threaded components). This completely avoids drilling, fully preserves the original waterproof structure of the corrugated steel sheet, eliminates leakage problems at the source, significantly extends the service life of the corrugated steel sheet roof and photovoltaic support structure, and reduces future maintenance costs.

[0013] Existing technologies require custom-made bolt holes or special clamps for different waveforms of color steel sheets, resulting in poor adaptability and high costs. In this invention, the inner clamping section of the steel frame clamp assembly can match the waveform of the color steel sheet, and the outer positioning corner piece rotates freely within the limiting opening ring via a limiting shaft, flexibly adapting to color steel sheets of different waveforms. Simultaneously, the guide rail assembly, through the cooperation of the limiting key and the profile guide rail slot, and the engagement of the rectangular boss and the guide rail flat section, eliminates the need to adjust the core component structure for different roofs and requires no customized processing, significantly reducing production and application costs.

[0014] In existing technologies, the tilt angle of photovoltaic modules is mostly a fixed value, or the adjustment structure is complex, making it difficult to optimize the angle according to different regional sunshine conditions, thus affecting power generation efficiency. This invention, through the cooperation of low-position pressure codes and L-shaped limiting slots on the positioning column, enables a wide range of free tilt angle adjustment for photovoltaic modules: the low-position pressure codes provide angular space for the rotation of the positioning column, multiple sets of L-shaped limiting slots on the positioning column can lock different tilt angle heights, and the edge and center pressure block components clamp the sides of the photovoltaic module through U-shaped slots, ensuring stable fixation after tilt angle adjustment. By optimizing the tilt angle, it can fully adapt to different regional sunshine conditions, significantly improving photovoltaic power generation efficiency. Attached Figure Description

[0017] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] Example 1 See Figure 1-13 As shown, the photovoltaic clamp for the roof of a color steel plate building provided in this embodiment is installed on the color steel plate 1 and supports the photovoltaic module 8. Specifically, it includes: Two sets of corresponding guide rail assemblies 3 are fixed above the color steel plate 1 by steel rib clamp assembly 2; Both sets of guide rail assemblies 3 are equipped with low-position lower pressure block assemblies 4; A high-position lower pressure block assembly 5 is provided on the low-position lower pressure block assembly 4; One end of the photovoltaic module 8 is mounted on the high lower pressure block component 5 on one of the guide rail components 3 through a pressing mechanism, and the other end is mounted on the low lower pressure block component 4 on another guide rail component 3. The steel rib clamp assembly 2 includes an inner positioning corner piece 2-1 and two sets of outer positioning corner pieces 2-2; The inner positioning corner piece 2-1 is divided into an L-shaped mounting section 2-17, an inner abutment section 2-15, and an inner clamping section 2-16 from top to bottom; Limiting opening rings 2-13 are provided on both sides of the connection between the L-shaped installation section 2-17 and the inner abutment section 2-15; The outer positioning corner piece 2-2 is divided into an outer abutment section 2-23 and an outer clamping section 2-24 from top to bottom; The top of the outer abutment section 2-23 is provided with a limiting shaft 2-21; The limiting shaft 2-21 of each set of external positioning corner pieces 2-2 is rotatably locked inside the limiting open ring 2-13; The inner clamping section 2-16 of the inner positioning corner piece 2-1 is fitted to the inner concave surface of the color steel plate 1; The inner abutting section 2-15 of the inner positioning corner piece 2-1 abuts against the outer abutting section 2-23 of the outer positioning corner piece 2-2; The outer clamping section 2-24 of the outer positioning corner piece 2-2 abuts against the bottom of the wave band of the color steel plate 1; The guide rail assembly 3 is connected to the L-shaped mounting section 2-17 of the inner positioning corner piece 2-1.

[0019] Specifically, the inner clamping section 2-16 of the inner positioning corner piece 2-1 fits against the inner surface of the color steel plate 1 wave, and the outer clamping section 2-24 of the outer positioning corner piece 2-2 abuts against the bottom of the color steel plate 1 wave. No drilling is required on the color steel plate 1 throughout the process, and the original waterproof layer and structural integrity of the color steel plate 1 are completely preserved, achieving non-penetrating mechanical interlocking fixation.

[0020] The limiting shaft 2-21 of the outer positioning corner piece 2-2 can rotate freely within the limiting opening ring 2-13, which can flexibly adjust the relative angle between the outer positioning corner piece 2-2 and the inner positioning corner piece 2-1, so that the inner clamping section 2-16 and the outer clamping section 2-24 can fit the color steel plate 1 band with different curvature and different width.

[0021] One end of the photovoltaic module 8 (such as a photovoltaic panel) is mounted on the high lower pressure block component 5 on one of the guide rail components 3 through a pressing mechanism, and the other end is mounted on the low lower pressure block component 4 on another guide rail component 3, so as to realize the inclined installation of the photovoltaic module 8.

[0022] Further optimization of the above scheme is carried out by providing an inner limiting screw hole 2-14 on the inner abutting section 2-15 of the inner positioning corner piece 2-1 and an outer limiting screw hole 2-22 on the outer abutting section 2-23 of the outer positioning corner piece 2-2. The inner limiting screw hole 2-14 corresponds to the outer limiting screw hole 2-22 and is fixed with threaded parts.

[0023] Specifically, see Figure 2 As shown, the threaded component consists of a first bolt 2-3 and a first nut 2-4 that mate with each other. The inner positioning corner piece 2-1 and the outer positioning corner piece 2-2 are fastened by bolt connection, so that they are reliably fastened to the color steel plate 1 and are easy to disassemble.

[0024] Further optimization of the above plan is needed; please refer to [link / reference]. Figure 5 , 6 As shown, the guide rail assembly 3 includes a profile guide rail 3-1 and a first rectangular boss 3-2; The profile guide rail 3-1 is divided into two guide rail sections 3-11, upper and lower. Each of the two guide rail sections 3-11 of the profile guide rail 3-1 is provided with a limiting groove 3-13; and slots 3-12 are provided on both sides of the profile guide rail 3-1. The bottom panel of the L-shaped mounting section 2-17 of the inner positioning corner piece 2-1 is provided with a positioning slot 2-12, and the side panel of the L-shaped mounting section 2-17 of the inner positioning corner piece 2-1 is provided with a limit key 2-11. The first rectangular boss 3-2 is provided with a first limiting boss 3-22, and the first rectangular boss 3-2 is provided with a first limiting platform 3-21 on both sides of the first limiting boss 3-22; A first threaded countersunk hole 3-23 is provided at the position of the first limiting boss 3-22, and a second screw 3-3 is screwed into the first threaded countersunk hole 3-23. The first rectangular boss 3-2 is fitted into the guide rail flat section 3-11 below the profile guide rail 3-1. The first limiting platform 3-21 is abutted against the limiting groove 3-13. The second screw 3-3 passes through the positioning slot 2-12 opened on the profile guide rail 3-1 and the inner positioning corner piece 2-1 in sequence, and is screwed with the second nut 3-4. The limiting key 2-11 on the inner positioning corner piece 2-1 is inserted into the slot 3-12 of the profile guide rail 3-1.

[0025] Specifically, the first rectangular boss 3-2 engages with the guide rail flat section 3-11 below the profile guide rail 3-1, and the first limiting platforms 3-21 on both sides directly abut against the limiting grooves 3-13 of the guide rail flat section 3-11, limiting the displacement of the guide rail; the limiting key 2-11 on the side panel of the inner positioning corner piece 2-1 engages with the groove 3-12 of the profile guide rail 3-1, further limiting the offset of the profile guide rail 3-1; the second screw 3-3 passes through the positioning slots 2-12 of the profile guide rail 3-1 and the inner positioning corner piece 2-1 in sequence and is screwed into the second nut 3-4, "tightening and fixing" the profile guide rail 3-1 and the inner positioning corner piece 2-1, preventing them from separating relative to each other. The triple structure works together to form a "three-dimensional constraint", which significantly improves the connection strength between the guide rail and the steel rib clamp, prevents loosening caused by vibration and external force, ensures the long-term safe operation of the photovoltaic module 8, and facilitates disassembly.

[0026] By cleverly utilizing the structural features of the profile guide rail 3-1, it is not necessary to make holes in the profile guide rail 3-1, thus avoiding damage to the overall strength of the profile guide rail 3-1. Moreover, the structural features of the profile guide rail 3-1 can enhance the structural strength, achieving two goals at once.

[0027] Further optimization of the above plan is needed; please refer to [link / reference]. Figure 7-10 As shown, the lower pressure block assembly 4 includes a lower pressure code 4-1 and a second rectangular boss 4-7. The low-position pressure code 4-1 includes sequentially pressure block installation section 4-16, connecting section 4-17, and pressure code installation section 4-18; A limiting slot 4-13 is provided on the connecting section 4-17, and a positioning screw hole 4-14 is provided on the connecting section 4-17. The limiting slot 4-13 on the connecting section 4-17 fits into the guide rail flat section 3-11 above the profile guide rail 3-1. The second rectangular boss 4-7 is provided with a second limiting boss 4-71, and the second rectangular boss 4-7 is provided with a second limiting platform 4-72 on both sides of the second limiting boss 4-71. A second threaded countersunk hole 4-73 is provided at the position of the second limiting boss 4-71, and a fourth screw 4-5 is screwed into the second threaded countersunk hole 4-73. The second rectangular boss 4-7 is engaged in the guide rail flat section 3-11 above the profile guide rail 3-1. The second limiting platform 4-72 is abutted against the limiting groove 3-13. The fourth screw 4-5 passes through the positioning screw hole 4-14 of the profile guide rail 3-1 and the connecting section 4-17 in sequence, and is screwed with the fourth nut 4-6. The block mounting section 4-16 is provided with a block mounting groove 4-19, and a high-position lower block assembly 5 is rotatably installed in the block mounting groove 4-19. The pressing and mounting section 4-18 has a pressing and mounting slot 4-20, and a whole-position pressing and mounting code 4-2 is rotatably installed in the pressing and mounting slot 4-20.

[0028] It should be noted that the second rectangular boss 4-7 has the same structure as the first rectangular boss 3-2.

[0029] Specifically, by engaging the limiting slot 4-13 onto the profile guide rail 3-1 and securing it with screws via the second rectangular boss 4-7, it is easy to disassemble. The lower pressure block assembly 4 can provide an installation base for the upper pressure block assembly 5 and the positioning pressure code 4-2, forming a height difference, thereby enabling the photovoltaic module 8 to be installed at an angle.

[0030] Specifically, see Figure 10-12 As shown, the high-position lower pressure block assembly 5 includes a positioning column 5-1, one end of which is set in the pressure block mounting groove 4-19 and can rotate; The entire column 5-1 is provided with several L-shaped limiting grooves 5-11 arranged along its column body direction; The clamping mechanism includes an edge clamping block assembly 6, which includes an edge clamping code 6-1. Each upright column 5-1 is provided with an edge clamping code 6-1. The edge pressing code 6-1 includes a first horizontal U-shaped slot 6-11 and a first vertical U-shaped slot 6-14 connected to the first horizontal U-shaped slot 6-11; The first upright U-shaped slot 6-14 is inserted into the L-shaped limiting slot 5-11, and the inclined side end of the photovoltaic module 8 is inserted into the first upright U-shaped slot 6-11; The whole-position pressing code 4-2 is provided with a pressing code U-shaped slot 4-21, and the inclined bottom end of the photovoltaic module 8 is inserted into the pressing code U-shaped slot 4-21.

[0031] Specifically, by changing the installation height of the edge clamp 6-1, the tilt angle of the photovoltaic module 8 can be adjusted.

[0032] Specifically, the first vertical U-shaped slot 6-14 is also provided with a connecting plate 6-12 and a first engagement plate 6-13. When the first vertical U-shaped slot 6-14 engages with the L-shaped limiting groove 5-11, the connecting plate 6-12 is pushed forward, and the first engagement plate 6-13 touches the vertical section of the L-shaped limiting groove 5-11 to achieve docking.

[0033] Specifically, the upright column 5-1 and the pressure block mounting groove 4-19 are rotated together by the following connection method: See Figure 8 , 10 As shown in Figure 11, arc-shaped holes 4-11 and limiting holes 4-12 are provided on both sides of the pressure block mounting groove 4-19, and the two arc-shaped holes 4-11 correspond to each other, and the two limiting holes 4-12 correspond to each other. A limit screw hole 5-12 and a rotation through hole 5-13 are provided at the bottom end of the positioning column 5-1; Align the limiting screw hole 5-12 and the arc-shaped hole 4-11, insert the fifth bolt 5-3, and tighten the fifth nut 5-2 to complete the connection; Align the rotating through hole 5-13 and the limiting hole 4-12, insert the sixth bolt 5-5, and tighten the sixth nut 5-4 to complete the connection.

[0034] The arc-shaped hole 4-11 allows the entire column 5-1 to rotate, thereby changing its tilt angle.

[0035] Specifically, the mounting slot 4-20 and the full-position pressing code 4-2 are rotated together by the following connection method: See Figure 7 , 8 As shown in Figure 9, rotating holes 4-15 are provided on both side walls of the pressure code mounting groove 4-20; A rotating screw hole 4-22 is opened on the integral pressure code 4-2; Align the rotating screw hole 4-22 and the rotating hole 4-15, insert the third bolt 4-4, and tighten the third nut 4-3 to achieve connection, so that the positioning pressure code 4-2 can be rotated and adjusted to adjust the angle of the pressure code U-shaped slot 4-21 to adapt to different tilt angles of the photovoltaic module 8.

[0036] Specifically, see Figure 13 As shown, the clamping mechanism also includes a central clamping block assembly 7, which includes a central clamping code 7-1. Each upright column 5-1 is provided with a side clamping code 6-1 or a central clamping code 7-1. The central pressure code 7-1 includes a second upright U-shaped slot 7-13 and two second horizontal U-shaped slots 7-11 respectively connected to the two side walls of the second upright U-shaped slot 7-13; The second U-shaped slot 7-13 is inserted into the L-shaped limiting slot 5-11, the inclined side end of the photovoltaic module 8 is inserted into the first U-shaped slot 6-11 or the second U-shaped slot 7-11, and the inclined bottom end of the photovoltaic module 8 is inserted into the pressing U-shaped slot 4-21.

[0037] Specifically, the central pressure code 7-1 can simultaneously support the sidewalls of two photovoltaic modules 8, and the tilt angle of the photovoltaic modules 8 can be adjusted by the installation height of the central pressure code 7-1.

[0038] Specifically, a second interlocking plate 7-12 is also provided inside the second upright U-shaped slot 7-13. When the second upright U-shaped slot 7-13 engages with the L-shaped limiting groove 5-11, the second interlocking plate 7-12 touches the vertical section of the L-shaped limiting groove 5-11 to achieve docking.

[0039] Specifically, see Figure 1 , 12 As shown in Figure 13, when multiple photovoltaic modules 8 need to be arranged side by side between two sets of guide rail assemblies 3, the edge clamping code 6-1 and the middle clamping code 7-1 can be used together. The outermost inclined sidewalls of the two outermost photovoltaic modules 8 are clamped by the edge clamping code 6-1, and the inclined sidewalls between the two sets of adjacent photovoltaic modules 8 in the middle are supported by the middle clamping code 7-1. This can shorten the distance between the two photovoltaic modules 8 and increase the number of photovoltaic modules 8.

[0040] like Figure 1 As shown, multiple photovoltaic modules 8 are arranged between two sets of guide rail assemblies 3. In actual installation, no fewer than two sets of guide rail assemblies 3 can be set, with multiple sets of guide rail assemblies 3 arranged side by side. The inclined sidewall of the photovoltaic module 8 in the first row is connected to the high lower pressure block assembly 5 on the low lower pressure block assembly 4 of the guide rail assembly 3 in the first row. The bottom end of the photovoltaic module 8 in the first row is connected to the full position pressure code 4-2 on the low lower pressure block assembly 4 of the guide rail assembly 3 in the second row.
