Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel splicing technology, and in particular to a detachable photovoltaic panel splicing device. Background Technology

[0002] With the rapid development of solar energy technology, photovoltaic (PV) power generation systems have been widely applied in various fields. As a core component of the system, the installation method of PV panels directly affects the system's stability, maintenance efficiency, and lifespan. Traditional PV panel installations often use direct bolt fixing or integral welding, which presents problems such as inconvenience in disassembly and replacement of damaged panels. Especially in large-scale PV arrays, multiple PV panel frames need to be modularly spliced, and there is also a need for rapid disassembly and replacement later on. Existing installation structures often lack flexibility and are difficult to achieve efficient and reliable unitized maintenance.

[0003] To address the aforementioned issues, some modular photovoltaic (PV) panel installation solutions have emerged in the market. However, these still involve fixing multiple PV panel frames in a rectangular array onto a steel frame, and then securing them with sheet metal welding or bolts. This results in low efficiency for disassembling and reassembling the PV panel joints. While some simple plug-in or snap-fit ​​designs can achieve quick assembly and disassembly at the joints, these joints are prone to loosening under long-term wind vibration and other external environments, affecting the overall structural reliability and safety.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] This utility model provides, for example Figures 1-5 The detachable photovoltaic panel splicing device shown includes a support mechanism 100, photovoltaic panel frames 200, mounting components 300, a second mounting plate 400, and a snap-fit ​​mechanism 500. Multiple photovoltaic panel frames 200 are spliced ​​on the top of the support mechanism 100. Multiple mounting components 300 are installed at the bottom of the splicing point of one of the photovoltaic panel frames 200. The second mounting plate 400 is disposed opposite to one end of the mounting component 300 and is installed at the bottom of the splicing point of adjacent photovoltaic panel frames 200. The snap-fit ​​mechanism 500 is installed between the mounting component 300 and the second mounting plate 400. The snap-fit ​​mechanism 500 is used for assembling and disassembling two adjacent photovoltaic panel frames 200 on the mounting component 300 and the second mounting plate 400, so that the photovoltaic panel frames 200 spliced ​​opposite each other can be quickly assembled and disassembled on the support mechanism 100.

[0047] The support mechanism 100 includes a fixed frame 101, a support plate 102, and a connector 103. The fixed frame 101 has a rectangular welded frame structure. The support plate 102 is fixed in the middle of the fixed frame 101 in a cross-shaped frame. The connector 103 is fixed in the inner corner frame formed by the fixed frame 101 and the photovoltaic panel frame 200. The connector 103 is used to fix the position of the photovoltaic panel frame 200 at the non-splicing part to the fixed frame 101, which helps to improve the stability of the position of multiple photovoltaic panel frames 200 on the support mechanism 100.

[0048] In addition, the mounting assembly 300 includes a first mounting plate 301 and a limiting assembly 302. The first mounting plate 301 is fixedly connected to the lower surface of the photovoltaic panel frame 200 by screws. The limiting assembly 302 is fixed to the bottom of the first mounting plate 301. The limiting assembly 302 is used to support and limit the connection between the snap-fit ​​mechanism 500 and the first mounting plate 301 and the second mounting plate 400, so that the mounting assembly 300, the second mounting plate 400 and the snap-fit ​​mechanism 500 can be stably supported at the bottom of the relatively spliced ​​photovoltaic panel frame 200. This facilitates the multiple photovoltaic panel frames 200 to form a whole and be stably placed on the top of the fixed frame 101 and the support plate 102, thereby improving the stability of the position of the multiple spliced ​​photovoltaic panel frames 200.

[0049] Specifically, the limiting component 302 includes a fixing block 321, a limiting post 322, a support block 323, wear-resistant pads 324, and chamfered edges 325. The fixing block 321 is fixed to the bottom of the first mounting plate 301, the limiting post 322 is fixed to one end of the fixing block 321, the support block 323 is rotatably inserted through one end of the limiting post 322, and multiple wear-resistant pads 324 are relatively fixed to both ends of the support block 323. The wear-resistant pads 324 are used to increase the frictional resistance between the snap-fit ​​mechanism 500 and the mounting component 300 and the second mounting plate 400. The wear-resistant pads 324 are made of wear-resistant rubber with a certain elasticity. Two chamfered edges 325 are diagonally opened on one side of the two wear-resistant pads 324. By rotating the support block 323, the support block 323 can support the bottom of the opposite end of the first mounting plate 301 and the second mounting plate 400, and the bottom of the support block 323 can support the snap-fit ​​mechanism 500. The 00 is pressed to further improve the stability of the snap-fit ​​mechanism 500, and the support block 323 can stably support the first mounting plate 301 and the second mounting plate 400, so that the splicing side of the two photovoltaic panel frames 200 can be stably supported on the support plate 102. The chamfered edge 325 makes it easy for the support block 323 to rotate on the first mounting plate 301, the second mounting plate 400 and the snap-fit ​​mechanism 500. The wear-resistant elasticity of the wear-resistant pad 324 allows the support block 323 to be squeezed and rotated between the first mounting plate 301, the second mounting plate 400 and the snap-fit ​​mechanism 500. By forcefully pushing one end of the support block 323, it is easy for the support block 323 to rotate between the support block 323 and the limiting post 322, so that the support block 323 is in a lateral state, and the disassembly and assembly of the snap-fit ​​mechanism 500 are not affected, which facilitates the disassembly and assembly between the two adjacent photovoltaic panel frames 200.

[0050] Furthermore, the locking mechanism 500 includes a first locking component 501, a second locking component 502, a compression spring 503, and a sliding rod 504. The first locking component 501 is fixed to the bottom of the first mounting plate 301. The second locking component 502 is horizontally slidably locked into the inner cavity of the first locking component 501, and the second locking component 502 can slide vertically out of the inner cavity of the first locking component 501. When the support block 323 is in a horizontal state, the second locking component 502... The top is unrestricted; pushing the second snap-fit ​​component 502 allows for the assembly and disassembly of the first snap-fit ​​component 501 and the second snap-fit ​​component 502. Multiple compression springs 503 are equidistantly fixed to the top of the second snap-fit ​​component 502. A sliding rod 504 is sleeved in the inner cavity of the compression spring 503. The sliding rod 504 is slidably inserted and connected to the bottom of the second mounting plate 400. The elasticity of the compression spring 503 facilitates the upward pulling of the second snap-fit ​​component 502 to achieve assembly and disassembly with the first snap-fit ​​component 501.

[0051] Furthermore, the first snap-fit ​​assembly 501 includes a snap-fit ​​piece 511 and protrusions 512. The snap-fit ​​piece 511 is fixed to the bottom of the first mounting plate 301, and one end of the snap-fit ​​piece 511 has an open annular structure. Multiple protrusions 512 are fixed to the inner wall of the opening at one end of the snap-fit ​​piece 511. Meanwhile, the second snap-fit ​​assembly 502 includes a snap-fit ​​block 521 and a groove 522. One end of the snap-fit ​​block 521 has a blunt triangular structure, and the snap-fit ​​block 521 is slidably connected to the inner cavity of the snap-fit ​​piece 511. The groove 522 is formed on both sides of the outer wall of the snap-fit ​​block 521, and the groove 522 is connected to the protrusions 512. The outer wall is movable and snap-fitted, making it easy for the snap-fit ​​block 521 to extend into the inner cavity of the snap-fit ​​piece 511, but difficult to pull the snap-fit ​​block 521 out of the inner cavity of the snap-fit ​​piece 511 horizontally. The compression spring 503 is fixed between the second mounting plate 400 and the snap-fit ​​block 521, and the bottom of the sliding rod 504 is fixedly connected to the top of the snap-fit ​​block 521. With the setting of the compression spring 503, when the bottom of the support block 323 does not press against the opposite end of the snap-fit ​​piece 511 and the protrusion 512, the snap-fit ​​block 521 can be pulled out of the inner cavity of the snap-fit ​​piece 511, which facilitates the quick disassembly between two adjacent photovoltaic panel frames 200.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
