Description

[Technical Field]

[0001] This utility model relates to the field of photovoltaic technology, specifically to an improved photovoltaic clamp and photovoltaic bracket. [Background Technology]

[0002] Currently, the installation of traditional photovoltaic modules on corrugated steel roofs typically relies on traditional photovoltaic support systems, as shown in the attached document. Figure 1-5 As shown, a photovoltaic support system typically includes multiple components such as a clamp 300, a track 400, and a center-side pressure block 200. The bottom of the clamp 300 is used to clamp the corrugated steel roof 500, and the top of the clamp 300 is connected to the track 400. The track 400 supports the photovoltaic modules 600, which are mounted on the track 400 and pressed firmly by the center-side pressure block 200. However, this structure has the following problems:

[0003] 1. It has many parts, a complex installation process, and takes a long time;

[0004] 2. High track costs increase the overall system cost;

[0005] 3. When clamp 300 is tightened using bolt assembly, the bolt head is at the bottom. One end of the wrench must be used to fix it and the other end to lock it. However, the bolt is easy to rotate during the tightening process, which affects the construction efficiency.

[0006] 4. The fixtures have poor versatility and are difficult to adapt to different tile types.

[0007] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. [Utility Model Content]

[0008] The present invention aims to solve the technical problems existing in the existing photovoltaic support system by providing an improved photovoltaic clamp and photovoltaic support. The improved photovoltaic clamp has the advantages of simple structure, convenient installation, low cost and strong applicability. The photovoltaic support is composed of the improved photovoltaic clamp and the middle side pressure block, which eliminates the traditional track structure and significantly reduces material cost and installation complexity.

[0009] This utility model is implemented as follows: An improved photovoltaic clamp includes a first clamp, a second clamp, and a bolt assembly. The first clamp and the second clamp are detachably connected by the bolt assembly. The first clamp includes a first upper top plate, a first support plate, and a first clamping plate, all integrally formed in a C-shape. The second clamp includes a second upper top plate, a second support plate, and a second clamping plate, all integrally formed in a C-shape. After assembly, the first and second clamps form a clamping cavity, with the second upper top plate abutting against the bottom surface of the first upper top plate. The bolt assembly includes polygonal bolts. The bottom surface of the second upper top plate is provided with a first hook portion and a second hook portion to restrict the rotation of the polygonal bolts. The first hook portion includes a first vertical limiting section and a first hook located at the bottom of the first vertical limiting section. The second hook portion includes a second vertical limiting section and a second hook located at the bottom of the second vertical limiting section.

[0010] Furthermore, a first abutting step is formed between the first vertical limiting segment and the first hook, and a second abutting step is formed between the second vertical limiting segment and the second hook; a groove for the bolt head of a polygonal bolt to be inserted is formed between the first vertical limiting segment and the second vertical limiting segment.

[0011] Furthermore, the side of the first hook facing the second hook is a first guide slope; the side of the second hook facing the first hook is a second guide slope.

[0012] Furthermore, a first through hole is formed in the middle of the first upper top plate for a polygonal bolt to pass through, and a second through hole is formed in the middle of the second upper top plate for a polygonal bolt to pass through.

[0013] Furthermore, the first perforation is a strip-shaped perforation, and the extension direction of the strip-shaped perforation is the width direction of the first upper top plate.

[0014] Furthermore, the first clamp and the second clamp are rotatably connected via a hinge unit.

[0015] Furthermore, the shaft unit includes a rotating semi-enclosing body and a rotating shaft. The rotating semi-enclosing body is located on the bottom surface of the first upper top plate at the end away from the first support plate, and the rotating shaft is located on the top of the second support plate.

[0016] Furthermore, the second support plate and the second top plate are connected by a connecting inclined plate, so that a clearance space is formed between the second support plate and the second top plate for the rotating semi-enclosed body to enter.

[0017] Furthermore, the polygonal bolt is a hexagonal bolt, and the bolt assembly also includes a first nut, a spring washer, and a flat washer.

[0018] On the other hand, a photovoltaic bracket includes a central pressure block and the improved photovoltaic clamp, wherein a third through hole is formed in the center of the central pressure block for a hexagonal bolt to pass through.

[0019] The advantages of this utility model are:

[0020] 1. Embodiment 1 provides an improved photovoltaic clamp, which, through innovative designs such as an integrated C-shaped clamp (first clamp, second clamp), an anti-rotation hook structure (first hook part and second hook part), a rotatable connection method (shaft unit), and strip-shaped perforations, can be used for edge or center fixing of photovoltaic modules. It realizes the multi-functionality, ease of installation, low cost, and wide applicability of photovoltaic clamps; it is particularly suitable for photovoltaic systems on industrial and commercial color steel tile roofs, significantly improving installation efficiency, reducing overall costs, and has good market promotion value.

[0021] 2. The improved photovoltaic clamp uses a first and second hook section as an anti-rotation hook structure, effectively limiting the rotation of the polygonal bolt during tightening. This facilitates installation, improves installation efficiency, avoids installation difficulties caused by bolt rotation, and enhances the stability and reliability of the clamp. By creating a groove between the first and second vertical limiting sections for the polygonal bolt head to engage, the clamp not only prevents the bolt head from rotating during tightening but also provides deformation capability. When the bolt head is pressed into the groove, it compresses the first and second hooks, causing the first and second vertical limiting sections to deform and open to both sides, widening the opening and facilitating the bolt head's insertion into the groove.

[0022] 3. Embodiment 2 provides a photovoltaic bracket, including a central pressure block and an improved photovoltaic clamp. The improved photovoltaic clamp and the central pressure block are combined to form a photovoltaic bracket, eliminating the traditional track structure and significantly reducing material costs and installation complexity.

Detailed Implementation Methods

[0044] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] Please see Figures 6 to 9 As shown, this embodiment provides an improved photovoltaic clamp 100, including a first clamp 1, a second clamp 2, and a bolt assembly 3. The first clamp 1 and the second clamp 2 are detachably connected by the bolt assembly 3. The first clamp 1 includes a first upper top plate 11, a first support plate 12, and a first clamping plate 13, all integrally formed in a C-shape. The second clamp 2 includes a second upper top plate 21, a second support plate 22, and a second clamping plate 23, all integrally formed in a C-shape. The opening of the first clamp 1 faces the second clamp 2, and the opening of the second clamp 2 faces the first clamp 1, so that after the first clamp 1 and the second clamp 2 are assembled, a clamping cavity 4 is formed, and the second upper top plate 21 abuts against the bottom surface of the first upper top plate 11. The clamping cavity 4 can adapt to various specifications of color steel tile roofs. The bolt assembly 3 includes polygonal bolts 31. The bottom surface of the second upper top plate 21 is provided with a first hook portion 24 and a second hook portion 25 that restrict the rotation of the polygonal bolts 31. Preferably, the first clamp 1 and the second clamp 2 are made using an aluminum alloy extrusion process.

[0047] The improved photovoltaic clamp 100 of this embodiment effectively restricts the rotation of the polygonal bolt 31 during the tightening process by setting the first hook part 24 and the second hook part 25 as an anti-rotation hook structure. This makes installation convenient, improves installation efficiency, avoids installation difficulties caused by bolt rotation, and enhances the stability and reliability of the clamp.

[0048] In this embodiment, the first hook portion 24 includes a first vertical limiting section 241 and a first hook 242 disposed at the bottom of the first vertical limiting section 241, and a first abutting step 243 is formed between the first vertical limiting section 241 and the first hook 242; the second hook portion 25 includes a second vertical limiting section 251 and a second hook 252 disposed at the bottom of the second vertical limiting section 251, and a second abutting step 253 is formed between the second vertical limiting section 251 and the second hook 252; a groove 26 for the bolt head of the polygonal bolt 31 to be inserted is formed between the first vertical limiting section 241 and the second vertical limiting section 251, and a locking opening 29 is formed between the first hook 242 and the second hook 252. By setting a groove 26 between the first vertical limiting section 241 and the second vertical limiting section 251 for the head of the polygonal bolt to be inserted, not only is it possible to prevent the head of the polygonal bolt 31 from rotating during tightening, but it also provides deformation capability. Specifically, when the head of the polygonal bolt 31 is pressed into the groove 26, the bolt head squeezes the first hook 242 and the second hook 252, causing the first vertical limiting section 241 and the second vertical limiting section 251 to deform and open to both sides, making the opening 29 larger and facilitating the insertion of the bolt head into the groove 26. By setting the first abutting step 243, the second abutting step 253, and the groove 26 to form a mechanical interlocking structure, the rotation of the polygonal bolt 31 is effectively prevented during tightening, further optimizing the bolt head limiting method, making its installation more convenient and accurate, and improving assembly precision. The three technical means of slot 26, hook part and top step work together to form multiple limits, making the improved photovoltaic clamp 100 more resistant to vibration and loosening.

[0049] In this embodiment, the side of the first hook 242 facing the second hook 252 is a first guide slope 2421; the side of the second hook 252 facing the first hook 242 is a second guide slope 2521. The guide slope is designed to guide the bolt head to easily engage with the slot 26 for automatic locking, reducing friction and resistance during installation and improving installation efficiency.

[0050] In this embodiment, a first through hole 111 for the polygonal bolt 31 to pass through is formed in the middle of the first upper top plate 11, and a second through hole 211 for the polygonal bolt 31 to pass through is formed in the middle of the second upper top plate 21. By providing through holes in the first upper top plate 11 and the second upper top plate 21, it is convenient for the polygonal bolt 31 to pass through and for the first clamp 1 and the second clamp 2 to be fastened. The structure is simple and the operation is convenient.

[0051] In this embodiment, the first perforation 111 is a strip-shaped perforation. The width direction is defined as the direction from near the first support plate 12 to away from the first support plate 12, and the extension direction of the strip-shaped perforation is the width direction of the first upper top plate 11. The strip-shaped perforation design, in conjunction with the hinge unit 5, allows the polygonal bolts 31 to be adjusted within a certain range, enhancing the adaptability of the improved photovoltaic clamp 100 to different installation environments.

[0052] In this embodiment, the first clamp 1 and the second clamp 2 are rotatably connected by a hinge unit 5. The hinge unit 5 enables the improved photovoltaic clamp 100 to adapt to roofs with different tile types, thereby improving versatility and installation flexibility.

[0053] In this embodiment, the shaft unit 5 includes a rotating semi-enclosing body 51 and a rotating shaft 52. The rotating semi-enclosing body 51 is disposed on the bottom surface of the first upper top plate 11 at the end away from the first support plate 12, and the rotating shaft 52 is disposed on the top of the second support plate 22. The mating structure of the rotating semi-enclosing body 51 and the rotating shaft 52 is simple and reliable, easy to manufacture and assemble, and reduces production costs. Preferably, the rotating semi-enclosing body 51 is formed with a semi-circular groove for the rotating shaft 52 to be inserted.

[0054] In this embodiment, the second support plate 22 and the second upper top plate 21 are connected by a connecting inclined plate 27, forming a clearance space 28 between the second support plate 22 and the second upper top plate 21 for the rotating semi-enclosed body 51 to enter. The design of the clearance space 28 ensures the smooth operation of the shaft page unit 5, avoids interference, and improves the rationality of the structure.

[0055] In this embodiment, the polygonal bolt 31 is a hexagonal bolt, and the bolt assembly 3 further includes a first nut 32, a spring washer 33, and a flat washer 34. Using standard hexagonal bolts and matching nuts and washers facilitates procurement and replacement, reduces maintenance costs, and enhances the product's market applicability.

[0056] The improved photovoltaic clamp 100 of this embodiment, through innovative designs such as an integrated C-shaped clamp (first clamp 1, second clamp 2), an anti-rotation hook structure (first hook part 24 and second hook part 25), a rotatable connection method (shaft unit 5), and strip-shaped perforations, can be used for edge or center fixing of photovoltaic modules 600 (see attached diagram). Figure 13 As shown in the figure, it realizes the multi-functionality, ease of installation, low cost and wide applicability of photovoltaic clamps; it is especially suitable for photovoltaic systems on industrial and commercial color steel tile roofs, which significantly improves installation efficiency, reduces overall cost and has good market promotion value.

[0057] Example 2

[0058] Please see Figures 6 to 13As shown, this embodiment provides a photovoltaic bracket, including a central pressure block 200 and the improved photovoltaic clamp 100 described in Embodiment 1. The central pressure block 200 has a third through hole 201 in its center for a hexagonal bolt to pass through. Combining the improved photovoltaic clamp 100 and the central pressure block 200 constitutes a photovoltaic bracket, eliminating the need for a traditional track structure and significantly reducing material costs and installation complexity.

[0059] The installation steps of the photovoltaic bracket in this embodiment are as follows:

[0060] Step 1: Assemble the first clamp 1 and the second clamp 2, insert the rotating shaft 52 into the rotating semi-enclosed body 51, and abut the second upper top plate 21 against the bottom surface of the first upper top plate 11; then the polygonal bolts 31 pass through the second through hole 211 and the first through hole 111 from bottom to top in sequence;

[0061] Step 2: The first clamping plate 13 and the second clamping plate 23 clamp the corrugated steel roof 500. Flat washers 34 and spring washers 33 are sequentially placed on the polygonal bolts 31. The improved photovoltaic clamp 100 is locked with the first nut 32 to simultaneously clamp the corrugated steel roof 500.

[0062] Step 3: Place the photovoltaic module 600 (photovoltaic panel) on the first upper top plate 11 of the first clamp 1. The polygonal bolt 31 passes through the third through hole 201 of the middle side pressure block 200. The middle side pressure block 200 presses down on the photovoltaic module 600. Finally, use the second nut 35 and washer to lock it.

[0063] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
