Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic installation technical field especially relates to a photovoltaic module quick installation guide rail structure. BACKGROUND

[0002] In the installation of distributed photovoltaic power generation system, especially when installing on the color steel tile roof, it is necessary to fix the photovoltaic module on the roof. Usually, the clamp is fixed on the corrugated color steel tile, and then the clamp and the photovoltaic module are connected through the guide rail. The clamp provides basic support and fixing point for the entire installation structure, while the guide rail is used to carry and fix the photovoltaic module and related cable bridge, operation and maintenance channel and other supporting facilities. Therefore, the clamp and the guide rail are the key components for carrying weight and achieving fixed installation in the photovoltaic installation of color steel tile roof.

[0003] In the prior art, the guide rail for fixing the photovoltaic module usually needs to be installed in steps. First, the clamp needs to be fixed on the corrugated color steel tile, which usually involves selecting a matching clamp according to the specifications and models of the corrugated color steel tile and preliminarily fixing it. Then, the guide rail is placed on the clamp that has been fixed, and a large number of fasteners (such as bolts, nuts, etc.) are used to fix the guide rail on the clamp one by one. Finally, the photovoltaic module is fixed on the guide rail by using the middle pressure plate and the side pressure plate in cooperation with the fasteners. This step-by-step installation and the use of a large number of fasteners make the entire installation process have many operation links and complicated steps. Especially when working on the roof, a large number of fasteners need to be frequently handled and tightened, which not only wastes time but also significantly increases the labor intensity of the installation personnel and reduces the installation efficiency.

[0004] In view of the above problems, the prior art needs to be improved. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at solving the problems existing in the prior art and provides a photovoltaic module quick installation guide rail structure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a photovoltaic module quick-installation guide rail structure, including a left clamp, on which an outer ring is symmetrically provided; a right clamp, on which an inner ring is provided, the inner ring being aligned with the outer ring, the left and right clamps being used to clamp corrugated steel sheets; a shaft, which passes through the inner and outer rings, and has a through hole on its surface; a pin, which is inserted into the through hole on the surface of the shaft, preventing the shaft from detaching from the inner and outer rings, the left and right clamps forming a clamp shape; a guide rail, which is integral with the left clamp, and has an inner groove, the guide rail being used to fix the photovoltaic panel; a trapezoidal strip, which is disposed between the left and right clamps, and has a threaded hole on its surface; and an adjusting bolt, which passes through the guide rail and is screwed into the threaded hole on the trapezoidal strip.

[0007] The photovoltaic module quick-installation guide rail structure of this application can be pre-assembled on the ground before use. Align the outer ring on the left clamp with the guide rail with the inner ring on the right clamp. Then, insert a shaft through the inner and outer rings, and insert a pin into the through hole on the shaft surface. The pin is elastically expandable, preventing the shaft from detaching from the inner and outer rings. At this point, the left and right clamps form a clamp, and the guide rail is integral with the left clamp. This pre-assembled structure can be easily carried to a corrugated steel roof. On the roof, move the pre-assembled installation structure to the designed installation point, aligning the jaws of the left and right clamps with the corrugated steel roof corrugations. Then, rotate the right clamp relative to the shaft to initially clamp the corrugated steel roof corrugations. Next, insert a trapezoidal strip between the left and right clamps. Insert an adjusting bolt through the guide rail and screw it into the threaded hole on the trapezoidal strip. The position of the trapezoidal strip is adjusted and positioned. Due to the wedge-shaped effect of the trapezoidal strip, its two sides abut against the inner walls of the left and right clamping parts, pushing the right clamping part to rotate further relative to the left clamping part. This allows the left and right clamping parts to effectively clamp the corrugated color steel sheet and fix the installation structure.

[0008] Furthermore, the structure also includes a central pressure plate or a side pressure plate placed on top of the guide rail. A fixing mechanism is provided between the central pressure plate or the side pressure plate and the guide rail. The fixing mechanism includes: a set bolt with a washer fitted on the shaft of the set bolt, the bolt head of the set bolt and the washer sliding into the inner groove of the guide rail; and a nut screwed into the thread of the set bolt. The central pressure plate or the side pressure plate is fixed to the guide rail by the set bolt, the washer and the nut.

[0009] Furthermore, the inner groove on the guide rail is used for the set bolt to slide against the washer.

[0010] Furthermore, the inclined surface on one side of the trapezoidal strip slides along the inner wall of the left part of the clamp, while the inclined surface on the other side abuts against the right part of the clamp.

[0011] Furthermore, the inner wall of the guide rail is provided with a slot.

[0012] Furthermore, the structure also includes a limiting sleeve that is fastened to the adjusting bolt. The limiting sleeve has circumferentially arranged retaining teeth that engage with the grooves on the inner wall of the guide rail.

[0013] Furthermore, the limiting sleeve is provided with a crossbar, and two horizontal grooves are formed in a circular array on the inner wall of the guide rail, and the crossbar rotates and is engaged in the horizontal groove.

[0014] Preferably, the end of the crossbar is made of an elastic material.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By designing the guide rail and the left clamp as a single unit, and incorporating a trapezoidal strip and adjusting bolts between the left and right clamps, rapid pre-assembly of the clamp and guide rail, and quick fixing on the roof, are achieved. Compared to the existing technology, which requires first fixing the clamp to the corrugated steel sheet, then securing the guide rail to the clamp with numerous fasteners, and finally fixing the photovoltaic panel, this invention significantly reduces the number of fasteners and operational steps required for on-site installation. It simplifies the installation process, reduces the labor intensity of high-altitude operations, and improves installation efficiency. It effectively solves the technical problems of cumbersome and labor-intensive photovoltaic module guide rail installation in existing technologies, offering advantages such as simple structure, rapid installation, and reliable fixing.

Detailed Implementation

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] During the installation of distributed photovoltaic (PV) power generation systems, especially on corrugated steel roofs, it is crucial to securely fix the PV modules to the roof structure. Traditional installation methods typically involve first fixing clamps to the corrugated steel roof, then connecting guide rails to the clamps using numerous fasteners, and finally fixing the PV modules to the guide rails. This step-by-step installation method, relying heavily on fasteners, results in numerous and cumbersome on-site operations, especially in high-altitude environments, which is not only time-consuming but also significantly increases the labor intensity of installers. To address the problems of cumbersome and labor-intensive PV module guide rail installation in existing technologies, this application proposes a rapid PV module installation guide rail structure. This structure integrates the guide rail 5 with the left clamp 1 and employs a unique hinged clamping mechanism using trapezoidal bars 14 and adjusting bolts 15. This enables rapid pre-assembly of the clamp and guide rail 5 and rapid fixation on the roof, simplifying the installation process, reducing the use of on-site fasteners, and lowering labor intensity.

[0027] like Figures 1 to 7 The photovoltaic module quick-installation guide rail structure shown includes: a left clamp 1, and an outer ring 2 symmetrically provided on the left clamp 1;

[0028] The right clamp 3 is provided with an inner sleeve 4, which is aligned with the outer sleeve 2. The left clamp 1 and the right clamp 3 are used to clamp the corrugated color steel sheet.

[0029] Shaft 6, which passes through inner ring 4 and outer ring 2, and has through holes on its surface;

[0030] Pin 7 is inserted into the through hole on the surface of shaft 6, so that shaft 6 cannot be separated from inner ring 4 and outer ring 2. The left clamp 1 and the right clamp 3 form a clamp shape.

[0031] Guide rail 5 is an integral part of the left clamp 1. Guide rail 5 has an inner groove 11 and is used to fix photovoltaic panel 16.

[0032] Trapezoidal bar 14 is disposed between the left part 1 and the right part 3 of the fixture, and the trapezoidal bar 14 is provided with threaded holes;

[0033] Adjusting bolt 15 passes through guide rail 5 and is screwed into the threaded hole on trapezoidal bar 14.

[0034] Compared to existing technologies where the clamp and guide rail are separate and require numerous fasteners, this application integrates the guide rail 5 with the left clamp component 1, significantly reducing the connection points and required fasteners between the clamp and guide rail. Furthermore, this application employs a hinged clamp with a trapezoidal bar 14 and adjusting bolts 15 as the clamping mechanism, replacing the direct bolt tightening method often used in traditional clamps, making the clamping process more efficient and convenient. This integrated and optimized clamping structure allows for extensive pre-assembly of the entire installation structure on the ground; upon arrival at the roof, only simple positioning and clamping operations are needed for fixation, greatly simplifying the on-site installation process and reducing the difficulty and labor intensity of high-altitude operations.

[0035] The photovoltaic module quick-installation guide rail structure of this application can be pre-assembled on the ground before use. The outer ring 2 on the left clamp 1 with guide rail 5 is aligned with the inner ring 4 on the right clamp 3. Then, a shaft 6 passes through the inner ring 4 and outer ring 2, and a pin 7 is inserted into the through hole on the surface of the shaft 6. The pin 7 can elastically expand, preventing the shaft 6 from disengaging from the inner ring 4 and outer ring 2. At this point, the left clamp 1 and right clamp 3 form a clamp shape, and the guide rail 5 is integral with the left clamp 1. This pre-assembled structure can be easily carried to a corrugated steel roof. On the roof, the pre-assembled installation structure is moved to the designed installation point, and the jaws of the left clamp 1 and right clamp 3 are aligned with the corrugated steel roof. Then, the right clamp 3 is rotated relative to the shaft 6, so that the left clamp 1 and right clamp 3 initially clamp the corrugated steel roof. Next, a trapezoidal strip 14 is placed between the left clamp 1 and right clamp 3. The adjusting bolt 15 is passed through the guide rail 5 and screwed into the threaded hole on the trapezoidal strip 14. The position of the trapezoidal strip 14 is adjusted and positioned. Due to the wedge-shaped action of the trapezoidal strip 14, its two sides abut against the inner walls of the left clamp 1 and the right clamp 3, pushing the right clamp 3 to rotate further relative to the left clamp 1. This allows the left clamp 1 and the right clamp 3 to effectively clamp the corrugated steel sheet, thus fixing the installation structure.

[0036] During this process, the left clamp 1 and the right clamp 3 achieve relative rotation through the hinge point formed by the shaft 6 and the pin 7 to adapt to the shape of the corrugated steel and generate clamping force. The guide rail 5, as an integral part of the left clamp 1, completes its installation and positioning after the clamp is fixed, providing a stable foundation for the subsequent fixing of the photovoltaic panel 16. The trapezoidal strip 14 and the adjusting bolt 15 work together to convert the rotational force of the adjusting bolt 15 into the linear movement and wedging action of the trapezoidal strip, thereby generating a strong clamping force and ensuring that the structure is firmly fixed to the corrugated steel sheet.

[0037] As one embodiment of this utility model, it also includes a central pressure plate 9 or a side pressure plate 10 placed on top of the guide rail 5. A fixing mechanism is provided between the central pressure plate 9 or the side pressure plate 10 and the guide rail 5. The fixing mechanism includes:

[0038] Set bolt 8 has a washer 12 fitted on its shaft, and the bolt head of set bolt 8 and washer 12 slide into the inner groove 11 of guide rail 5;

[0039] Nut 13 is screwed into the screw of set bolt 8. The middle pressure plate 9 or side pressure plate 10 is fixed to the guide rail 5 by set bolt 8, washer 12 and nut 13. The inner groove 11 on the guide rail 5 is used for sliding between set bolt 8 and washer 12.

[0040] In practice, this fixing mechanism is a conventional structure used to fix the photovoltaic panel 16 to the guide rail 5, and its importance lies in providing reliable support and fixation for the photovoltaic panel. The set bolt 8, washer 12, and nut 13 are standard components for achieving clamping fixation. The inner groove 11 on the guide rail 5 provides space for the bolt head of the set bolt 8 and the washer 12 to slide in and be positioned, allowing the set bolt 8 to move freely along the length of the guide rail 5 to adjust the position of the center pressure plate 9 or the side pressure plate 10, accommodating photovoltaic panels 16 of different sizes or for layout adjustments. The center pressure plate 9 is typically used to fix the middle portion of the photovoltaic panel 16, while the side pressure plate 10 is used to fix the edge portion of the photovoltaic panel 16.

[0041] As one embodiment of this utility model, the inclined surface on one side of the trapezoidal strip 14 slides along the inner wall of the left clamp 1, while the inclined surface on the other side abuts against the right clamp 3.

[0042] In practice, the shape of the trapezoidal strip 14 and its mating relationship with the left clamp 1 and the right clamp 3 are key to achieving effective clamping. The inclined surface of the trapezoidal strip 14, in conjunction with the inner wall of the clamp, forms a wedge-shaped structure. As the trapezoidal strip 14 moves up along the inclined surface of the inner wall of the left clamp 1, its width gradually increases, and the inclined surface on its side wall exerts an outward pushing force on the right clamp 3. Since the left clamp 1 and the right clamp 3 are hinged by the shaft 6, this outward pushing force causes the right clamp 3 to rotate inward, thereby clamping the corrugated steel sheet located at its jaws. One side of the trapezoidal strip 14 slides along the inner wall of the left clamp 1, while the other side abuts against the right clamp 3, ensuring that the trapezoidal strip 14 can stably apply force to both sides of the clamp during movement, thus effectively converting the rotational force of the adjusting bolt 15 into a clamping force on the corrugated steel sheet.

[0043] As one embodiment of this utility model, a slot is provided on the inner wall of the guide rail 5.

[0044] As one embodiment of this utility model, it also includes a limiting sleeve 20, which is fastened to the adjusting bolt 15. The limiting sleeve 20 is provided with a circumferentially arranged locking tooth 17, which engages with the locking groove on the inner wall of the guide rail 5.

[0045] In practice, the limiting sleeve 20 and its engagement with the adjusting bolt 15 and the groove on the inner wall of the guide rail 5 constitute a locking mechanism to prevent the adjusting bolt 15 from loosening. After the adjusting bolt 15 is tightened to the correct position, allowing the trapezoidal strip 14 to clamp the corrugated steel sheet, the limiting sleeve 20 is fastened onto the adjusting bolt 15. The engagement of the retaining teeth 17 on the limiting sleeve 20 with the groove on the inner wall of the guide rail 5 effectively restricts the rotation and axial movement of the limiting sleeve 20 within the guide rail 5. Since the limiting sleeve 20 is fastened onto the adjusting bolt 15, its fixation indirectly limits the adjustment bolt 15, preventing it from loosening due to vibration or other reasons during use. Loosening of the adjusting bolt 15 may cause displacement of the trapezoidal strip 14, thereby affecting the clamping effect of the fixture on the corrugated steel sheet, leading to loosening or even detachment of the installation structure. Therefore, setting the limiting sleeve 20 can significantly improve the long-term stability and safety of the installation structure.

[0046] As one embodiment of this utility model, the limiting sleeve 20 is provided with a crossbar 19, and two horizontal grooves 18 are arranged in a circular array on the inner wall of the guide rail 5. The crossbar 19 rotates and is inserted into the horizontal grooves 18.

[0047] In practice, the engagement of the crossbar 19 with the transverse groove 18 serves as a locking structure to further secure the limiting sleeve 20 and prevent its rotation and axial movement. When the crossbar 19 is engaged in the transverse groove 18, the vertical movement of the limiting sleeve 20 is restricted, thereby more reliably preventing the adjusting bolt 15 from loosening.

[0048] As one embodiment of this utility model, the end of the crossbar 19 is made of an elastic material.

[0049] In practice, the elastic design of the end of the crossbar 19 makes it easier to insert the crossbar 19 into the transverse groove 18 on the inner wall of the guide rail 5. The elastic end can deform during insertion, making it easier to enter the transverse groove 18, and returns to its original shape after being inserted, thus forming a tighter fit with the transverse groove 18. This elastic fit not only makes the insertion process smoother and reduces installation difficulty, but also provides a certain preload after insertion, making the crossbar 19 more firmly fixed in the transverse groove 18 and less prone to loosening due to vibration. At the same time, when disassembly is required, the elastic end is also easier to remove from the transverse groove 18, improving the convenience of maintenance and disassembly.

[0050] Working principle of this utility model:

[0051] The photovoltaic module quick-installation guide rail structure of this application can be pre-assembled on the ground before use. The outer ring 2 on the left clamp 1 with guide rail 5 is aligned with the inner ring 4 on the right clamp 3. Then, a shaft 6 passes through the inner ring 4 and outer ring 2, and a pin 7 is inserted into the through hole on the surface of the shaft 6. The pin 7 can elastically expand, preventing the shaft 6 from disengaging from the inner ring 4 and outer ring 2. At this point, the left clamp 1 and right clamp 3 form a clamp shape, and the guide rail 5 is integral with the left clamp 1. This pre-assembled structure can be easily carried to a corrugated steel roof. On the roof, the pre-assembled installation structure is moved to the designed installation point, and the jaws of the left clamp 1 and right clamp 3 are aligned with the corrugated steel roof. Then, the right clamp 3 is rotated relative to the shaft 6, so that the left clamp 1 and right clamp 3 initially clamp the corrugated steel roof. Next, a trapezoidal strip 14 is placed between the left clamp 1 and right clamp 3. The adjusting bolt 15 is passed through the guide rail 5 and screwed into the threaded hole on the trapezoidal strip 14. The position of the trapezoidal strip 14 is adjusted and positioned. Due to the wedge-shaped action of the trapezoidal strip 14, its two sides abut against the inner walls of the left clamp 1 and the right clamp 3, pushing the right clamp 3 to rotate further relative to the left clamp 1. This allows the left clamp 1 and the right clamp 3 to effectively clamp the corrugated steel sheet, thus fixing the installation structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
