Description

Technical Field

[0001] This invention is specifically for the connection of photovoltaic panels installed on roof structures, and particularly refers to a photovoltaic bracket. Background Technology

[0002] A photovoltaic (PV) mounting system refers to a support system used to support and secure solar panels. Solar panels are typically mounted on these systems and generate electricity by converting sunlight into electricity. PV mounting systems are usually made of materials such as aluminum alloy, steel, and stainless steel, and can be categorized into fixed mounting systems and single-axis, dual-axis, and tri-axis tracking mounting systems, depending on the specific requirements. Fixed mounting systems are typically fixed to the ground or roof, offering better stability and are suitable for smaller power generation systems. Tracking mounting systems, on the other hand, have single-axis, dual-axis, or tri-axis tracking capabilities, allowing for automatic tracking based on the sun's position and angle of illumination, thus increasing the power generation capacity of the PV system. The design of PV mounting systems needs to consider various factors, such as weight, wind resistance, corrosion resistance, and adaptability, to ensure their safe, reliable, and efficient operation.

[0003] There is a support mechanism specifically designed for corrugated steel roof tiles, patent number 202222087616.X, patent name: Locking Block for Connecting Photovoltaic Modules to the Roof. This locking block acts directly on the reinforcing ribs of the corrugated steel roof tile, replacing the method of fixing the photovoltaic module with connectors. This solves the problem that drilling holes in the corrugated steel roof tile would significantly reduce the rain-shielding effect (the purpose of the holes is to allow the connectors to be installed on the corrugated steel roof tile). However, the installation of this locking block structure is relatively complex, requiring the use of other tools, such as screwdrivers. In addition, it is necessary to ensure that the two hooks are matched with the purlins before screwing in the screws to lock the two hooks. In other words, during the screw-tightening stage, it is necessary to hold the two hooks on the purlins with one hand. Especially since this operation is on the roof, if you are not careful, the parts can fall directly off the roof, causing great damage. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a photovoltaic bracket designed to solve the issue of complex installation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a photovoltaic bracket, including a pair of clamping parts held on a purlin, characterized in that the clamping parts are slidably connected, and the slidable connection is achieved by mutually adapted sliding grooves and sliders on the clamping parts, wherein the groove spacing and the width of the slider gradually decrease along their own length in a single direction until a gap fit is formed between the slider and the groove.

[0006] The advantages of this invention lie in replacing the traditional method that relies on external instruments, and shortening the installation steps and time through sliding installation. Furthermore, the slider and groove eliminate the need for screws, further optimizing the overall structure. The reduction in the number of parts simplifies the entire installation process. The slider and groove, which replace screws, utilize a locking effect based on their gradually decreasing width and groove spacing, replacing screw fixation. Combined with the adaptability between the groove and the slider, the entire installation process is simpler and smoother. Attached Figure Description

[0014] like Figure 1-2 As shown, this embodiment is a photovoltaic support for positioning photovoltaic modules on a corrugated steel sheet. The photovoltaic support is configured such that a locking part 2 and a support part 3 forming a locking structure are disposed on the upstream and downstream sides of the photovoltaic module. A connecting part (not shown in the figure) passes through the locking part 2 in the direction X and is inserted into the interior of the support part 3 to press the photovoltaic module on the support part 3 to form a locked state. A clamping part is installed below the support part to hold the purlin 1 on the corrugated steel sheet. The support part 3 is hollow inside and is equipped with a positioning member 5 that is inclined relative to the connecting part, so that the through hole 9 (not shown in the figure) on the positioning member 5 is formed by the connecting part penetrating at a wedge-shaped slope.

[0015] It is understood that this locking method utilizes a wedge-shaped inclination to promote expansion and generate greater friction, thereby achieving a stronger locking effect. Compared with the existing vertical assembly method, the locking method of this invention uses a double-link locking mechanism, which not only retains the original through-hole fixing performance, but also changes the volume of the connection part by increasing internal energy to form expansion, thereby increasing the contact area and friction. This avoids the inconsistent wear levels mentioned in the prior art and solves the problem of photovoltaic panels becoming loose or shaking.

[0016] In other words, the photovoltaic module is fixed by being clamped, and the photovoltaic module is positioned by the gap between the locking part 2 located above the photovoltaic module and the support part 3 located below the photovoltaic module.

[0017] Furthermore, the tilt of the through hole 9 can further enhance the suppression of shaking of the connection.

[0018] Therefore, in conjunction with the elongated shape of the support part 3, it has a stronger anti-bending effect when facing the wind.

[0019] In the embodiment, the locking part 2 and the supporting part 3 are arranged to be connected to each other through the connecting part. The locking part 2 is a rectangular body with a wing 4 at its upper edge. After the locking part 2 is installed on the supporting surface through the connecting part, the area between the wing 4 and the supporting surface forms a locking area for pressing the photovoltaic module.

[0020] In this embodiment, the connecting part can be either a self-tapping screw or a connecting screw. The above is only an illustrative example and is not a further limitation on the connecting part. Further selection of the type of connecting part can be made according to the actual situation.

[0021] It should be noted that the X direction is from top to bottom, and the self-tapping screws pass sequentially through the locking part 2, the support part 3, and the support member 5 within the support part 3. The through hole 9 is formed by the self-tapping screw passing through the support member 5. Multiple positioning members 5 are provided within the support part 3, and the positioning members 5 are installed in a crisscross manner. In this embodiment, there are eight positioning members 5, which form a mesh structure. This structure aims to increase the transmission path of axial force, guiding the axial force to the entire support part 3 and enhancing the stability of the connection within the support part.

[0022] Specifically, the locking part 2 is provided with a screw hole 21.

[0023] It should also be noted that the length of the support part 3 is 3-5 meters. The above is only an example, and the specific length can be selected according to the requirements.

[0024] exist Figure 2In this context, the position of the through hole 9 is not unique. Depending on the setting position of the screw hole 21, the through hole 9 can be located in the middle part of the positioning member 5, or in other areas of the positioning member 5.

[0025] The clamping part 6 and the support part 3 are slidably connected. The clamping part 6 is provided in a set. The clamping part 6 is adapted to the purlin 1 to clamp and fix the purlin 1. The side of the clamping part 6 and the side of the support part 3 are provided with mutually parallel slots 7. The two ends of the retaining ring 8 can be inserted into the slots 7 to make the connection between the clamping part 6 and the support part 3 more stable.

[0026] The retaining ring 8 is C-shaped. For example... Figure 3-4 As shown, the clamping between the two clamping parts 6 is achieved through a sliding connection, specifically:

[0027] The first clamping part is provided with a sliding groove 61, and the second clamping part is provided with a slider 62. The slider 62 and the sliding groove 61 are mutually adapted. The slider 62 is embedded in the sliding groove 61. At the same time, the groove spacing in the sliding groove 61 and the width of the slider 62 gradually decrease along their own length in a single direction. Therefore, after the slider 62 moves a certain distance in the sliding groove 61, the two sides of the slider 62 form a clearance fit with the sliding groove 61.

[0028] Therefore, this sliding installation method can reduce labor costs and prevent the slider 62 from detaching from the groove 61.

[0029] Specifically, a slide rail 10 is provided on the top surface of the second clamping part, and a protrusion 63 is provided on the top surface of the first clamping part. The support part 3 moves to the protrusion 63 via the slide rail 10 and squeezes the protrusion 63, so that the second clamping part presses down on the purlin 1 in a staggered manner to increase the contact area between the clamping part 6 and the purlin 1. In addition, the clamping ends of the clamping part 6 are approximately "V" shaped by rotating 45° counterclockwise and 45° clockwise, respectively. Therefore, the staggered clamping effect can fully contact all surfaces of the purlin 1.

[0030] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
