Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to an adaptive plastic photovoltaic panel fixing component. Background Technology

[0002] With the continuous growth of photovoltaic (PV) system installations, PV panel fasteners, as key components connecting PV panels to support frames, directly affect the installation efficiency, operational stability, and economical maintenance of PV systems. Currently available PV panel fasteners still have significant technical shortcomings. For example, most fasteners are non-detachable, requiring replacement of the entire unit if a part is damaged, significantly increasing maintenance costs and workload. Furthermore, the adaptability of these fasteners is also poor. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adaptive plastic photovoltaic panel fastener, specifically achieved through the following technical solution: An adaptive plastic photovoltaic panel fastener includes a fixing component, a locking component, and a supporting component; The fixing component includes a connecting plate, and at least one pair of first connecting blocks are fixedly installed on the top of the connecting plate; each pair of first connecting blocks is located on the same straight line and has a gap between them; A fixing component is fixedly installed at the bottom of the connecting plate. The supporting component includes a supporting block, a second connecting block is fixedly installed on the bottom of the supporting block, and a second limiting groove is provided on one side of the supporting block along its length. The second connecting block is located between a pair of first connecting blocks and is detachably connected to the first connecting blocks; The locking component is located on the side of the support block where the second limiting groove is opened, and is detachably connected to the support block; The locking component has a first limiting groove facing the second limiting groove.

[0004] The fixing component is a fixing plate, which is perpendicular to the connecting plate, and the fixing plate has several first through holes.

[0005] The fastener is a fastening sleeve.

[0006] The length of the fixing sleeve is the same as the length of the connecting plate.

[0007] The connecting plate has a clearance groove that matches the second connecting block.

[0008] There are two pairs of first connecting blocks, and the two pairs of first connecting blocks are respectively fixedly installed on both sides of the top of the connecting plate; a supporting component is installed between each pair of first connecting blocks, and the second limiting grooves of the two supporting components are arranged back to back.

[0009] It also includes a gasket, which is installed between the locking member and the supporting member.

[0010] Both sides of the fixing plate are fixedly installed with protrusions corresponding to the first through hole, and the first through hole passes through the corresponding protrusion.

[0011] The connecting plate has a sixth through hole, and the length direction of the sixth through hole is consistent with the length direction of the connecting plate.

[0012] A positioning groove is provided on the bottom wall of the first limiting groove, a positioning plate is slidably installed in the positioning groove, a vertical positioning column is fixedly installed on the top of the positioning plate, and a receiving groove matching the positioning column is provided on the top wall of the first limiting groove.

[0013] The technical solution of this utility model has the following advantages: The adaptive plastic photovoltaic panel fastener disclosed in this utility model effectively solves the technical defects of existing photovoltaic panel fasteners, such as complex structure, low installation efficiency, limited applicable scenarios, and high maintenance costs, through the structural design and optimized cooperation relationship of the fastening component, locking component, and supporting component.

[0014] All components are detachably connected using bolts. No special connecting tools or complex assembly procedures are required, simplifying the assembly process.

[0015] The top of the fixing component can be designed with two pairs of first connecting blocks. One or two supporting components can be flexibly selected to be installed according to the position requirements of the photovoltaic array. When two supporting components are installed, the profiles of two adjacent photovoltaic panels can be fixed at the same time. When one supporting component is installed, this utility model is used at the edge of the photovoltaic array, and only one photovoltaic panel needs to be fixed.

[0016] The detachable connection structure between components means that if a single component malfunctions later, only the corresponding bolt needs to be removed to replace the individual component, without having to replace the entire set of fasteners, which greatly reduces maintenance costs and workload.

[0017] This utility model, through its replaceable components and elongated hole design, breaks through the limitations of existing fasteners on the single adaptability to bracket type, profile specifications, and installation scenario, and can be widely applied to different photovoltaic installation environments, significantly improving its versatility.

[0018] This invention significantly improves installation efficiency and economy while ensuring the reliability of photovoltaic panel fixing. It also expands the scope of application of the product, has high practical value and market application prospects, and fully meets the photovoltaic industry's technical requirements for "efficient, universal and reliable" fixing components.

[0025] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] This utility model provides an adaptive plastic photovoltaic panel fixing component, with attachment Figure 1 and attached Figure 5 The structures shown represent two different embodiments of this utility model.

[0027] The adaptive plastic photovoltaic panel fastener is used to fix the frame of the photovoltaic panel. The frame is composed of profile 3, which is existing technology and will not be described in detail here.

[0028] Appendix Figure 1 This is one embodiment of the present utility model.

[0029] The structure of the adaptive plastic photovoltaic panel fastener in this embodiment is shown in the attached figure. Figure 1 As shown, it includes a first fixing component 1, a locking component 2, and a supporting component 4. The first fixing component 1 is fixed to the bracket by bolts, the supporting component 4 is installed on the first fixing component 1 by bolts, and the locking component 2 is installed on one side of the supporting component 4 by bolts. The profile 3 is clamped between the locking component 2 and the supporting component 4.

[0030] In this embodiment, the first fixing component 1, the locking component 2, and the supporting component 4 are all injection molded.

[0031] Each component is injection molded from plastic material, which significantly reduces weight compared to traditional metal fasteners, greatly reducing the load pressure on the photovoltaic bracket and lowering the strength design requirements and cost of the bracket.

[0032] The structure of the first fixing component 1 is shown in the attached figure. Figure 2 As shown, it includes a plate-shaped first connecting plate 108, and a fixing plate 101 is fixedly installed at the bottom middle position of the first connecting plate 108. The fixing plate 101 is perpendicular to the first connecting plate 108, that is, the top of the fixing plate 101 is fixedly connected to the bottom of the first connecting plate 108.

[0033] In this embodiment, the width of the fixing plate 101 is smaller than the width of the first connecting plate 108, but it can be adjusted according to the actual situation.

[0034] The fixing plate 101 has four first through holes 103 arranged in a rectangular array. These first through holes 103 are oblong holes. The number of first through holes 103 can also be set according to requirements.

[0035] Both sides of the fixing plate 101 are fixedly installed with protrusions 102 corresponding to the first through hole 103, and the first through hole 103 passes through the corresponding protrusions 102.

[0036] The protrusion 102 is used to strengthen the structure and ensure that the structure is more stable when the fixing plate 101 is installed on the bracket; to avoid loosening of the fixing due to wind and vibration during long-term use.

[0037] The protrusion 102 on the fixing plate 101 is integrated with the first through hole 103, which enhances the structural strength of the fixing plate 101 without the need for additional reinforcing parts.

[0038] The fixing plate 101 has a first through hole 103 in the shape of an elongated oval. During installation, it is not necessary to precisely align the mounting holes of the bracket. The position of the fixing component can be slightly adjusted along the length of the elongated oval hole to compensate for the positional deviation of the bracket during installation and avoid repeated disassembly and reassembly due to errors.

[0039] Two cylindrical first connecting blocks 104 are fixedly installed on both sides of the top of the first connecting plate 108, and the axes of the two first connecting blocks 104 coincide. A gap is left between the two first connecting blocks 104 located on the same side.

[0040] A second through hole 106 is provided on the first connecting block 104, and the axis of the second through hole 106 coincides with the axis of the first connecting block 104.

[0041] The length direction of the first connecting block 104 is consistent with the length direction of the first connecting plate 108.

[0042] As attached Figure 2As shown, each of the two first connecting blocks 104 has a countersunk hole 107 at one end that is far apart from each other, and the axis of the countersunk hole 107 coincides with the axis of the second through hole 106.

[0043] The countersunk hole 107 on the first connecting block 104 is coaxial with the second through hole 106, which not only hides the bolt head but also eliminates the need for additional processing of the hidden structure, further simplifying the overall structure.

[0044] The structure of locking component 2 is shown in the attached figure. Figure 3 As shown, it includes a body 201, and a first limiting groove 202 is provided on one side wall of the body 201 along the length direction of the body 201.

[0045] The main body 201 is also provided with three third through holes 203, which are arranged in a linear array along the length of the main body 201.

[0046] The third through hole 203 extends through the body 201 along the width direction of the body 201.

[0047] The three third through holes 203 are all located below the first limiting groove 202.

[0048] The structure of the supporting component 4 is shown in the attached figure. It includes a supporting block 401. A cylindrical second connecting block 402 is fixedly installed at the bottom of the supporting block 401. The length direction of the second connecting block 402 is consistent with that of the supporting block 401, and the connection between the supporting block 401 and the second connecting block 402 is smoothly transitioned.

[0049] The second connecting block 402 has a fourth through hole 403, the axis of which coincides with the axis of the second connecting block 402.

[0050] A second limiting groove 405 is provided on one side wall of the support block 401 along the length direction of the support block 401.

[0051] The support block 401 is also provided with three fifth through holes 404, which are arranged in a linear array along the length of the support block 401.

[0052] The fifth through hole 404 and the third through hole 203 are in one-to-one correspondence.

[0053] All three fifth through holes 404 are located below the second limiting groove 405.

[0054] The number of the fifth through hole 404 and the third through hole 203 can also be different from three; there can be two, four, or other numbers.

[0055] The distance from the center of the fifth through hole 404 to the bottom wall of the second limiting groove 405 is equal to the distance from the center of the third through hole 203 to the bottom wall of the first limiting groove 202.

[0056] The second connecting block 402 is located between two first connecting blocks 104 on the same side of the top of the first connecting plate 108. The first connecting bolt passes through one first connecting block 104, the second connecting block 402, and the other first connecting block 104 in sequence before installing the nut, thus completing the connection between the supporting component 4 and the first fixing component 1.

[0057] The locking component 2 is located on the side of the support block 401 where the second limiting groove 405 is opened, and the first limiting groove 202 faces the second limiting groove 405. The second connecting bolt passes through the second limiting groove 405 and the third through hole 203 in sequence, and then the nut is installed to complete the connection between the locking component 2 and the support block 401.

[0058] The first limiting groove 202 faces the second limiting groove 405.

[0059] The top of the locking component 2 is located below the top wall of the second limiting groove 405.

[0060] The bottom wall of the second limiting groove 405 is flush with the bottom wall of the first limiting groove 202.

[0061] The first limiting groove 202 and the second limiting groove 405 are arranged opposite to each other, and their bottom walls are flush. When clamping the profile 3, the profile 3 can be subjected to uniform force, avoiding local stress concentration in the profile 3 caused by misalignment of the two limiting grooves.

[0062] The first connecting plate 108 is provided with a clearance groove 105 that matches the second connecting block 402. The clearance groove 105 is located between the two first connecting blocks 104 on the same side of the top of the first connecting plate 108.

[0063] Usage status as shown in the attached figure. Figure 1 As shown, the main body of profile 3 is engaged in the second limiting groove 405, and the extension plate of profile 3 is engaged in the first limiting groove 202; the limiting members on the bracket clamp the fixing plate 101 from both sides, and the fixing plate 101 is fixed by the third connecting bolt.

[0064] In this embodiment, two cylindrical first connecting blocks 104 are fixedly installed on both sides of the top of the first connecting plate 108, so two supporting components 4 can be installed. At this time, the second limiting grooves 405 on the two supporting components 4 are arranged facing away from each other. In this case, the present invention is used between two adjacent photovoltaic panels.

[0065] When this invention is used at the edge of a photovoltaic panel array, only one supporting component 4 needs to be installed.

[0066] Of course, when this utility model is used on the edge of a photovoltaic panel array, two first connecting blocks 104 can be installed only on the top of the first connecting plate 108. These two first connecting blocks 104 can be installed on one side of the first connecting plate 108 or in the middle of the first connecting plate 108.

[0067] This utility model also provides another embodiment of the adaptive plastic photovoltaic panel fastener, the structure of which is shown in the attached figure. Figure 5 As shown.

[0068] The adaptive plastic photovoltaic panel fastener in this embodiment includes a locking component 2, a supporting component 4, and a second fixing component 5. The structures of the locking component 2 and the supporting component 4 are exactly the same as those in Embodiment 1.

[0069] In this embodiment, the locking component 2, the supporting component 4, and the second fixing component 5 are all injection molded.

[0070] The structure of the second fixing component 5 is shown in the attached figure. Figure 6 As shown, it includes a second connecting plate 502, and a cylindrical fixing sleeve 501 is fixedly installed at the bottom of the second connecting plate 502. The length of the fixing sleeve 501 is the same as the length of the second connecting plate 502.

[0071] The fixing sleeve 501 is cylindrical.

[0072] Two first connecting blocks 104 are fixedly installed on the top of the second connecting plate 502. The structure of the first connecting block 104 is exactly the same as that of the first connecting block 104 in Embodiment 1.

[0073] The top of the second connecting plate 502 is also provided with a clearance groove 105, which is located between the two first connecting blocks 104.

[0074] The second connecting plate 502 has a sixth through hole 503, and the length direction of the sixth through hole 503 is consistent with the length direction of the second connecting plate 502.

[0075] In this embodiment, the connection method between the locking component 2 and the supporting component 4 is exactly the same as the connection method in Embodiment 1; the connection method between the supporting component 4 and the second fixing component 5 is the same as the connection method between the supporting component 4 and the first fixing component 1 in Embodiment 1.

[0076] The fixing sleeve 501 in this embodiment can also be applied to Embodiment 1 to replace the fixing plate 101. In this case, at least one sixth through hole 503 needs to be opened on the first connecting plate 108.

[0077] The aforementioned fixing sleeve 501 is used to fit onto the round tube that makes up the bracket, and then the fixing sleeve 501 is clamped from both ends by the limiting member on the bracket and fixed by bolts.

[0078] Of course, the fixing sleeve 501 can also be directly fixed to the corresponding bracket by heat fusion. In this case, no other limiting parts are needed on the bracket, and no bolts are needed in the sixth through hole 503. It only serves to reduce weight.

[0079] In actual use, the length of the extension plate of different profiles 3 will vary, as shown in the attached figure. Figure 7 As shown, when the extension plate is long, at least one gasket 6 is installed between the locking component 2 and the supporting component 4. The gasket 6 has a seventh through hole corresponding to the third through hole 203. The gasket 6 can be used in all embodiments of this utility model.

[0080] This utility model also provides another embodiment of the locking component 2, as shown in the attached figure. Figure 8 As shown, in this embodiment, the main structure of the locking component 2 is the same as in the previous embodiment. The difference is that a positioning groove is provided on the bottom wall of the first limiting groove 202, and a positioning plate 205 is slidably installed in the positioning groove. A vertical positioning post 206 is fixedly installed on the top of the positioning plate 205. A receiving groove 204 matching the positioning post 206 is provided on the top wall of the first limiting groove 202. That is, after the positioning plate 205 is installed in place, a part of the positioning post 206 will be in the receiving groove 204. Of course, the receiving groove may not be provided. In this case, the positioning post 206 can abut against the top wall of the first limiting groove 202 or have a clearance fit.

[0081] The positioning plate 205 and the positioning post 206 constitute a complete positioning component. When the extension plate of the profile 3 has positioning holes, this positioning component is used to insert the positioning post 206 into the positioning holes, facilitating the installation of the locking component 2. When the extension plate of the profile 3 does not have positioning holes, this positioning component is not used.

[0082] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
