Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, and in particular to an integrated structure of photovoltaic module clamping guide rail. Background Technology

[0002] In the installation of distributed photovoltaic systems on corrugated steel roofs, existing technologies typically employ separate clamps and guide rails. Specifically, firstly, matching aluminum alloy clamps must be selected based on the corrugated steel roof's specifications and fixed to the corrugations. Next, guide rails, used to secure the photovoltaic panels and associated cable trays, maintenance access channels, etc., are fixed to the installed clamps. Finally, the photovoltaic panels are secured to the guide rails using guide rails and pressure blocks (such as center pressure plates and side pressure plates).

[0003] This modular installation method results in a cumbersome operation process, requiring multiple positioning and tightening steps, and using a large number of fasteners. The large number of fasteners not only increases installation time and labor intensity, especially in the context of high-altitude rooftop work, but also increases the risk of loosening at connection points. Once a fastener loosens, it may affect the stability and safety of the entire photovoltaic module array. Therefore, the existing technology for installing photovoltaic modules on rooftop corrugated steel sheets suffers from technical problems such as cumbersome operation, numerous fasteners, high risk of loosening, and unfavorable conditions for rooftop work.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated structure for photovoltaic module clamping guide rails.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated structure of photovoltaic module clamping guide rail, including a guide rail, which is used to support the photovoltaic panel and provide an installation track;

[0007] The clamp has a left clamp and a right clamp, which cooperate to clamp corrugated steel sheets. The left clamp is slidably connected to the groove at the bottom of the guide rail.

[0008] Set bolt, which is used to securely connect the left and right parts of the clamp;

[0009] A limiting mechanism is provided between the left and right clamping parts to limit the left clamping part in the groove at the bottom of the guide rail;

[0010] A central pressure plate or a side pressure plate is placed on top of the guide rail. The central pressure plate or the side pressure plate is used to press and fix the photovoltaic panel. A positioning mechanism is provided between the central pressure plate or the side pressure plate and the top of the guide rail.

[0011] When installing photovoltaic modules using the integrated structure of the photovoltaic module clamping guide rail of this utility model, the length of the guide rail and the spacing of the clamps are first determined according to the installation requirements. The left clamp is pre-slidably connected to the groove at the bottom of the guide rail, but not fully fixed yet. Then, the installer moves the guide rail with clamps to the installation position and places the left clamp in the appropriate position on the corrugated steel sheet. Since the left clamp is slidable in the groove of the guide rail, its position can be easily adjusted to align with the corrugated steel sheet. After adjusting the position of the left clamp, the right clamp is connected to the left clamp and fixed with set bolts. During the process of fixing the left and right clamps to hold the corrugated steel sheet, the relative movement of the left and right clamps will trigger the limiting mechanism set between them. Once activated, the limiting mechanism generates a force that limits or locks the left clamp piece into the groove at the bottom of the guide rail, thus simultaneously fixing the clamp to the corrugated steel roof and to the guide rail. The guide rail, acting as a load-bearing component, is then securely fixed to the roof by the clamp. After fixing the clamp and guide rail, the photovoltaic panel is placed at the predetermined position on top of the guide rail. Finally, using a center pressure plate or side pressure plate in conjunction with the positioning mechanism, the photovoltaic panel is pressed and fixed to the guide rail.

[0012] Furthermore, the limiting mechanism includes:

[0013] A sliding cavity is formed through the top of the left part of the clamp, and an inner support rod is vertically slidably connected inside the sliding cavity;

[0014] A tapered rod is fixedly connected to the bottom of the inner support rod;

[0015] The limiting block is located at the top of the left part of the clamp and is fixedly connected to the upper end of the inner support rod.

[0016] More specifically, the top of the left part of the clamp is provided with a sliding plate that engages with the groove at the bottom of the guide rail.

[0017] Preferably, the left part of the fixture has a connecting groove on its side wall, and the right part of the fixture has an arc-shaped rod at its end. The arc-shaped rod is engaged in the connecting groove so as to attach the right part of the fixture to the left part of the fixture.

[0018] In addition, the set bolt passes through the left and right parts of the clamp, and together with the set nut, it fixes the right part of the clamp to the left part of the clamp.

[0019] Furthermore, a limiting groove is provided in the slide groove at the bottom of the guide rail to cooperate with the limiting block to complete the compression.

[0020] In addition, the top of the guide rail is provided with a mounting groove for fixing the middle pressure plate or the side pressure plate.

[0021] More specifically, the positioning mechanism includes a large-headed bolt, a flat washer, and a nut. The bolt head of the large-headed bolt is located in the mounting groove on the guide rail, and the shank of the large-headed bolt passes through the middle pressure plate or the side pressure plate. The flat washer and the nut are connected to the large-headed bolt to fix the middle pressure plate or the side pressure plate to the guide rail.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] By integrating the guide rail and clamp (including the left and right clamp parts) into a single design, the clamp can be directly slidably connected to the groove at the bottom of the guide rail. During the clamping and fixing of the corrugated steel roof, a limiting mechanism between the left and right clamp parts simultaneously limits and fixes the left clamp part in the groove at the bottom of the guide rail. This integrated and synchronous fixing mechanism significantly simplifies the installation process of photovoltaic modules on corrugated steel roofs, avoiding the step-by-step operation of first fixing the clamp and then fixing the guide rail to the clamp in existing technologies, thus reducing installation steps and the number of fasteners required. The reduction in fasteners not only lowers material costs and installation labor intensity, but more importantly, it significantly reduces the risk of loosening at connection points, improving the stability and safety of the entire photovoltaic module array. Therefore, this invention effectively solves the technical problems of cumbersome photovoltaic module installation operations, numerous fasteners, high risk of loosening, and unfavorable conditions for rooftop operations in existing technologies, improving installation efficiency and system reliability.

[0030] 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.

[0031] Photovoltaic power generation, as a clean energy source, is increasingly widely used, especially in the field of distributed photovoltaics, where corrugated steel roofs have become an important installation platform due to their widespread distribution. However, installing photovoltaic modules on corrugated steel roofs faces many challenges. Existing technologies typically employ separate clamp and guide rail systems. During installation, the clamps must first be fixed to the corrugated steel roof, then the guide rails are connected and fixed to the clamps, and finally the photovoltaic panels are secured using the guide rails. This step-by-step installation method is not only complex and time-consuming, but also requires numerous fasteners due to the many connection points, increasing installation costs and the potential risk of loosening, while also making high-altitude operations more difficult and dangerous. To overcome these shortcomings of existing technologies, this invention proposes an integrated structure for photovoltaic module clamps and guide rails.

[0032] like Figures 1 to 5 The photovoltaic module clamp guide rail integrated structure shown includes:

[0033] Guide rail 1 is used to support photovoltaic panel 16 and provide an installation track;

[0034] The left clamp 7 and the right clamp 8 are used to clamp the corrugated color steel sheet. The left clamp 7 is slidably connected to the groove at the bottom of the guide rail 1.

[0035] Set bolt 11 is used to fix the left part 7 of the clamp to the right part 8 of the clamp.

[0036] A limiting mechanism is provided between the left clamp 7 and the right clamp 8 to limit the left clamp 7 in the groove at the bottom of the guide rail 1;

[0037] The medium pressure plate 2 or the side pressure plate 3 is placed on the top of the guide rail 1. The medium pressure plate 2 or the side pressure plate 3 is used to press and fix the photovoltaic panel 16. A positioning mechanism is provided between the medium pressure plate 2 or the side pressure plate 3 and the top of the guide rail 1.

[0038] Compared with the separate clamp and guide rail installation methods in existing technologies, the integrated structure of the photovoltaic module clamp and guide rail of this utility model has significant advantages. In existing technologies, the clamp needs to be fixed separately to the corrugated steel sheet first, and then the guide rail needs to be aligned and fixed to the clamp. This process requires multiple positioning and tightening, which is cumbersome, and the connection between the clamp and the guide rail is an additional connection point, increasing the risk of loosening. In this utility model, the left clamp piece 7 is directly slidably connected to the bottom of the guide rail 1. During installation, simply place the guide rail 1 with the clamp on the roof, slide the left clamp piece 7 to the appropriate position, and then connect and fix the right clamp piece 8 to the left clamp piece 7. While the left and right clamp pieces are holding the corrugated steel sheet, the limiting mechanism inside the clamp automatically locks the left clamp piece 7 in the groove of the guide rail 1, realizing the simultaneous fixation of the clamp to the roof and the clamp to the guide rail. This integrated design and synchronous fixing mechanism greatly simplifies the installation process, reduces the number of fasteners required, and lowers installation time and labor intensity. Especially in high-altitude working environments, it improves installation efficiency and safety and effectively reduces the risk of connection loosening.

[0039] When installing photovoltaic modules using the integrated structure of the photovoltaic module clamp guide rail of this utility model, the length of the guide rail 1 and the spacing of the clamps are first determined according to the installation requirements. The left clamp 7 is pre-slidably connected to the groove at the bottom of the guide rail 1, but not completely fixed yet. Then, the installer moves the guide rail 1 with clamps to the installation position and places the left clamp 7 in the appropriate position on the corrugated steel sheet. Since the left clamp 7 is slidable in the groove of the guide rail 1, its position can be easily adjusted to align with the corrugated steel sheet. After adjusting the position of the left clamp 7, the right clamp 8 is connected to the left clamp 7 and fixed with the set bolt 11. During the process of fixing the left clamp 7 and the right clamp 8 to clamp the corrugated steel sheet, the relative movement of the left and right clamps will trigger the limiting mechanism set therebetween. Once activated, the limiting mechanism generates a force that limits or locks the left clamp 7 into the groove at the bottom of the guide rail 1, thus simultaneously fixing the clamp to the corrugated steel roof and the clamp relative to the guide rail 1. The guide rail 1, acting as a load-bearing component, is then securely fixed to the roof by the clamp. After fixing the clamp and guide rail, the photovoltaic panel 16 is placed at a predetermined position on top of the guide rail 1. Finally, using the center pressure plate 2 or side pressure plate 3, in conjunction with the positioning mechanism, the photovoltaic panel 16 is pressed and fixed onto the guide rail 1.

[0040] In this process, guide rail 1 provides a stable installation foundation and track; left clamp 7 and right clamp 8 are responsible for reliable connection with the corrugated steel roof tiles; set bolt 11 ensures tight fit between the left and right clamps; the limiting mechanism is key to achieving synchronous fixation of the clamps to the guide rail, automatically locking the clamps on the guide rail when they clamp the roof; the central pressure plate 2 or side pressure plate 3 and the positioning mechanism are responsible for firmly fixing the photovoltaic panels to the guide rail. The entire process is significantly simplified compared to existing technologies, reducing installation steps and the use of fasteners, improving installation efficiency and system reliability, and effectively solving the problems of cumbersome installation and high risk of loosening in existing technologies.

[0041] As one embodiment of this utility model, the limiting mechanism includes:

[0042] A sliding cavity is formed through the top of the left part 7 of the fixture, and an inner support rod 14 is vertically slidably connected inside the sliding cavity;

[0043] The tapered rod 13 is fixedly connected to the bottom of the inner support rod 14;

[0044] The limiting block 15 is located at the top of the left part 7 of the clamp and is fixedly connected to the upper end of the inner support rod 14. The guide rail 1 has a limiting groove in the slide groove at the bottom to cooperate with the limiting block 15 to complete the extrusion.

[0045] In practice, the sliding cavity is a channel located inside the left clamp 7, its shape and size matching the inner support rod 14, allowing the inner support rod 14 to slide vertically within it. The inner support rod 14 is a moving component in the limiting mechanism, with a tapered rod 13 connected to its bottom and a limiting block 15 connected to its top. The tapered rod 13 has a tapered or inclined structure designed to interact with the wedge block 12 on the right clamp 8. When the right clamp 8 approaches and is secured to the left clamp 7, the wedge block 12 squeezes or pushes the tapered rod 13. Since the tapered rod 13 is connected to the bottom of the inner support rod 14, this squeezing or pushing force is converted into an upward thrust, driving the inner support rod 14 to move upward within the sliding cavity. The limiting block 15 is fixed to the upper end of the inner support rod 14, and as the inner support rod 14 moves upward, the limiting block 15 also moves upward. The shape and position of the limiting block 15 are designed to make contact and rub against the limiting groove on the inner wall of the slide groove at the bottom of the guide rail 1.

[0046] As one embodiment of this utility model, the top of the left clamp 7 is provided with a sliding plate that cooperates with the groove at the bottom of the guide rail 1.

[0047] In practice, the sliding plate serves as the specific structure for the sliding connection between the left clamp 7 and the guide rail 1, allowing the left clamp 7 to easily engage in the groove at the bottom of the guide rail 1 and slide along the direction of the groove. This mating structure ensures that the movement of the left clamp 7 on the guide rail 1 is stable and smooth, while also providing reliable support and a working basis for the subsequent limiting mechanism.

[0048] As one embodiment of this utility model, a connecting groove 10 is provided on the side wall of the left clamp 7, and an arc-shaped rod 9 is provided at the end of the right clamp 8. The arc-shaped rod 9 is inserted into the connecting groove 10 to splice the right clamp 8 onto the left clamp 7.

[0049] In practice, the connection groove 10 and the arc-shaped rod 9 provide a convenient and quick way to connect the left and right clamp parts. During installation, the arc-shaped rod 9 of the right clamp part 8 can be aligned and snapped into the connection groove 10 of the left clamp part 7, thus achieving the initial connection and positioning of the right clamp part 8 to the left clamp part 7. This connection method allows the left and right clamp parts to maintain their relative positions before final bolt fixing, facilitating subsequent operations by installers. By adopting the snap-fit ​​structure of the connection groove and arc-shaped rod, the assembly process of the left and right clamp parts is simplified, improving the efficiency of on-site installation.

[0050] In one embodiment of this utility model, the set bolt 11 passes through the left clamp 7 and the right clamp 8, and together with the set nut, fixes the right clamp 8 and the left clamp 7.

[0051] In practice, the left clamp 7 and the right clamp 8 are provided with through holes for the set bolt 11 to pass through. After the right clamp 8 and the left clamp 7 are spliced ​​together (for example, by the engagement of the arc rod 9 and the connecting groove 10) and the position is adjusted, the set bolt 11 is passed through these through holes and the set nut is screwed on the other side for tightening.

[0052] As one embodiment of this utility model, the top of the guide rail 1 is provided with a mounting groove for fixing the middle pressure plate 2 or the side pressure plate 3.

[0053] In practice, the mounting groove is one or more channels extending along the length of the guide rail 1 and formed on the top of the guide rail 1. The cross-sectional shape of the mounting groove is designed to accommodate the head of the positioning mechanism used to fix the center pressure plate 2 or the side pressure plate 3, for example, a T-slot, a square slot, or other groove-shaped structure suitable for the bolt head to slide into and be locked in.

[0054] As one embodiment of this utility model, the positioning mechanism includes a large-headed bolt 4, a flat washer 5, and a nut 6. The bolt head of the large-headed bolt 4 is located in the mounting groove on the guide rail 1, and the shaft of the large-headed bolt 4 passes through the middle pressure plate 2 or the side pressure plate 3. The flat washer 5 and the nut 6 are connected to the large-headed bolt 4 to fix the middle pressure plate 2 or the side pressure plate 3 to the guide rail 1.

[0055] In implementation, after placing the photovoltaic panel 16 on the guide rail 1, the intermediate pressure plate 2 or side pressure plate 3 is placed above the edge of the photovoltaic panel 16 and aligned with the mounting groove at the top of the guide rail 1. The bolt head of the large-headed bolt 4 is slid into the mounting groove of the guide rail 1, and its position is adjusted so that its shaft passes through the pre-drilled hole on the intermediate pressure plate 2 or side pressure plate 3. Then, the flat washer 5 is placed on the shaft of the large-headed bolt 4, and the nut 6 is tightened. By tightening the nut 6, the intermediate pressure plate 2 or side pressure plate 3 is pressed against the edge of the photovoltaic panel 16, and at the same time, the head of the large-headed bolt 4 is pulled tight and locked into the mounting groove of the guide rail 1, thereby firmly fixing the intermediate pressure plate 2 or side pressure plate 3 and the pressed photovoltaic panel 16 to the guide rail 1. This positioning mechanism uses standard fasteners to achieve reliable fixing of the photovoltaic panel on the guide rail, and is simple to operate and easy to adjust.

[0056] Working principle of this utility model:

[0057] When installing photovoltaic modules using the integrated structure of the photovoltaic module clamp guide rail of this utility model, the length of the guide rail 1 and the spacing of the clamps are first determined according to the installation requirements. The left clamp 7 is pre-slidably connected to the groove at the bottom of the guide rail 1, but not completely fixed yet. Then, the installer moves the guide rail 1 with clamps to the installation position and places the left clamp 7 in the appropriate position on the corrugated steel sheet. Since the left clamp 7 is slidable in the groove of the guide rail 1, its position can be easily adjusted to align with the corrugated steel sheet. After adjusting the position of the left clamp 7, the right clamp 8 is connected to the left clamp 7 and fixed with the set bolt 11. During the process of fixing the left clamp 7 and the right clamp 8 to clamp the corrugated steel sheet, the relative movement of the left and right clamps will trigger the limiting mechanism set therebetween. Once activated, the limiting mechanism generates a force that limits or locks the left clamp 7 into the groove at the bottom of the guide rail 1, thus simultaneously fixing the clamp to the corrugated steel roof and the clamp relative to the guide rail 1. The guide rail 1, acting as a load-bearing component, is then securely fixed to the roof by the clamp. After fixing the clamp and guide rail, the photovoltaic panel 16 is placed at a predetermined position on top of the guide rail 1. Finally, using the central pressure plate 2 and side pressure plate 3, in conjunction with the positioning mechanism, the photovoltaic panel 16 is pressed and fixed onto the guide rail 1.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
