Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel installation, and in particular to a spring-loaded snap-on fixing structure for photovoltaic panel installation. Background Technology

[0002] In the construction of photovoltaic power plants and the installation of distributed photovoltaic systems, the fixing of photovoltaic panels is one of the core aspects of ensuring the stable operation of the power generation system. Currently, the mainstream methods for fixing photovoltaic panels in the industry mainly rely on bolt connections, metal block welding, or traditional snap-fit ​​structures. These methods have many problems that urgently need to be solved in practical applications: Traditional bolted connections require tightening each bolt individually, which is especially time-consuming and labor-intensive in large-scale photovoltaic array installations. Furthermore, the installation efficiency is low due to the skill level of the installers and the availability of appropriate tools. Additionally, adjustments cannot be made beforehand, and the limited space during installation when splicing two photovoltaic panels makes it inconvenient for workers and also affects installation efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a spring-clip type fixing structure for photovoltaic panel installation, which can effectively solve the problems of low installation efficiency and large limitations caused by the need to use tools to rotate bolts in traditional installation, as well as the problem of multiple operation steps affecting installation efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A spring-loaded snap-on fixing structure for photovoltaic panel installation includes a rectangular clip, a fixing base fixedly mounted on the top of the rectangular clip, a fixing rod fixedly mounted on the top of the fixing base, a pressing component on the outer wall of the fixing rod, and a tension spring and a compression spring sleeved thereon, the pressing component including a central pressure block, which compresses the compression spring and pulls the tension spring when it moves vertically upward, the inner wall of the fixing base is provided with a pressing component, and the outer wall is provided with a locking component, a protective cover fixedly mounted on the top of the fixing rod, the bottom of the protective cover having an annular groove, an annular plate fixedly mounted on the top of the central pressure block, the annular plate being completely fitted and slidingly engaged with the inner wall of the annular groove, and the top of the fixing base having several guide grooves.

[0005] Preferably, the clamping assembly further includes a plurality of guide rods, each of which is fixedly connected to the bottom of the intermediate pressure block and slidably engaged with the corresponding guide groove. The intermediate pressure block is slidably sleeved on the fixed rod. The two ends of the compression spring are respectively connected to the top of the intermediate pressure block and the inner wall of the protective cover, and the two ends of the tension spring are respectively connected to the bottom of the intermediate pressure block and the inner wall of the fixed base.

[0006] Preferably, the extrusion assembly includes a rotating shaft, an extrusion block, two torsion springs, and a lever. The rotating shaft is rotatably connected to the inner wall of the fixed base. The extrusion block is fixedly sleeved on the outer wall of the rotating shaft and abuts against the bottom of the intermediate pressure block. The two torsion springs are respectively sleeved at both ends of the rotating shaft, and both ends are respectively connected to the extrusion block and the inner wall of the fixed base. The lever is fixedly connected to the extrusion block.

[0007] Preferably, the extrusion assembly further includes a crossbar, which is fixedly connected to the lever, and one end of the crossbar has an insertion hole that passes through the crossbar.

[0008] Preferably, the locking assembly includes two fixed seats, two insertion rods, and four limiting blocks. The two fixed seats are respectively fixedly connected to one end of the fixed base. The two insertion rods are slidably engaged with the two fixed seats and can be inserted into the insertion hole when moving horizontally. The diameter of the insertion rod is the same as the inner diameter of the insertion hole. The four limiting blocks are respectively fixedly sleeved on the two insertion rods, and their diameter is larger than that of the insertion rods.

[0009] Preferably, the locking assembly further includes an arc-shaped plate, which is fixedly installed at the bottom of the two fixed seats. An arc-shaped groove is provided on the top of the arc-shaped plate. When the rotating shaft rotates at a certain angle, the lever matches the arc-shaped groove.

[0010] Preferably, a protective plate is fixedly installed on the inner wall of the fixed base, and a limiting groove is formed at one end of the protective plate, and the lever slides in cooperation with the limiting groove.

[0011] Preferably, the bottom of the intermediate pressure block is provided with a slot, the extrusion block slides in the slot, the inner wall of the slot is an inclined surface, when the extrusion block rotates, its end slides along the inclined surface of the slot, and pushes the intermediate pressure block to move vertically upward along the fixed rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the cooperation of tension spring, compression spring and two torsion springs, a certain force can be applied to the middle pressure block, so that when the middle pressure block is no longer locked, it can slide vertically upward and squeeze the two photovoltaic panels, thus achieving rapid installation.

[0013] 2. Through the cooperation of the extrusion component and the locking component, the lever can easily drive the extrusion block to rotate, and the extrusion block pushes the intermediate pressure block when rotating, reducing the difficulty of adjusting the intermediate pressure block. At the same time, the two plug rods can lock the lever and the crossbar, and the position of the intermediate pressure block can be adjusted in advance before installation and then locked. During installation, the two plug rods are slid horizontally out of the plug hole, which can quickly make the intermediate pressure block extrude and lock the photovoltaic panel, further improving the installation efficiency.

[0014] 3. Through the cooperation between the crossbar and the arc groove, when the crossbar is rotated into the arc groove, the worker can press the crossbar with one hand and slide the insertion rod with the other hand. This allows for quick adjustment and installation by a single person, further reducing installation difficulty, improving work efficiency, and making it highly applicable.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Example 1 like Figure 1-2As shown, a spring-loaded snap-on fixing structure for photovoltaic panel installation includes a rectangular clip 1. A fixing base 2 is fixedly installed on the top of the rectangular clip 1. A fixing rod 5 is fixedly installed on the top of the fixing base 2. A pressing component 3 is provided on the outer wall of the fixing rod 5, and a tension spring 501 and a compression spring 502 are sleeved thereon. The pressing component 3 includes a middle pressure block 301. When the middle pressure block 301 moves vertically upward, it squeezes the compression spring 502 and pulls the tension spring 501. A pressing component 4 is provided on the inner wall of the fixing base 2, and a locking component 7 is provided on the outer wall. A protective cover 6 is fixedly installed on the top of the fixing rod 5. An annular groove 601 is opened at the bottom of the protective cover 6. An annular plate 302 is fixedly installed on the top of the middle pressure block 301. 2. The fixed base 2 is completely fitted to the inner wall of the annular groove 601 and slides in fit. The top of the fixed base 2 is provided with several guide grooves 203. The pressing assembly 3 also includes several guide rods 304. The guide rods 304 are all fixedly connected to the bottom of the middle pressure block 301 and slide in fit with the corresponding guide grooves 203. The middle pressure block 301 is slidably sleeved on the fixed rod 5. The two ends of the compression spring 502 are respectively connected to the top of the middle pressure block 301 and the inner wall of the protective cover 6. The two ends of the tension spring 501 are respectively connected to the bottom of the middle pressure block 301 and the inner wall of the fixed base 2. The inner wall of the fixed base 2 is fixedly installed with a protective plate 201. One end of the protective plate 201 is provided with a limit groove 202. The lever 404 slides in fit with the limit groove 202.

[0019] In this embodiment, the compression spring 502 and the tension spring 501 apply force to the middle pressure block 301, so that after the middle pressure block 301 moves vertically upward a certain distance, it can be squeezed downward without the interference of external forces, thereby squeezing and locking the two photovoltaic panels. At the same time, the protective cover 6, the annular plate 302, and the protective plate 201 can protect the tension spring 501, the compression spring 502, and the torsion spring 403 respectively, reducing the probability of the structure being damaged by long-term exposure to the outside and extending the service life of the equipment.

[0020] Example 2 like Figure 2-5As shown, in one embodiment, the extrusion assembly 4 includes a rotating shaft 401, an extrusion block 402, two torsion springs 403, and a lever 404. The rotating shaft 401 is rotatably connected to the inner wall of the fixed base 2. The extrusion block 402 is fixedly sleeved on the outer wall of the rotating shaft 401 and abuts against the bottom of the intermediate pressure block 301. The two torsion springs 403 are respectively sleeved on both ends of the rotating shaft 401, and both ends are respectively connected to the extrusion block 402 and the inner wall of the fixed base 2. The lever 404 is fixedly connected to the extrusion block 402. The locking assembly 7 includes two fixed seats 701, two insert rods 704, and four limiting blocks 705. The two fixed seats 701 are respectively fixed to the inner wall of the fixed base 2. One end of the fixed base 2 is fixedly connected, and two insertion rods 704 are slidably engaged with two fixed seats 701 respectively. They can be inserted into the insertion hole 406 when moving horizontally. The diameter of the insertion rod 704 is the same as the inner diameter of the insertion hole 406. Four limiting blocks 705 are fixedly sleeved on the two insertion rods 704 respectively, and their diameter is larger than that of the insertion rods 704. The bottom of the middle pressure block 301 is provided with a slot 303. The pressing block 402 is slidably engaged with the slot 303. The inner wall of the slot 303 is an inclined surface. When the pressing block 402 rotates, its end slides along the inclined surface of the slot 303 and pushes the middle pressure block 301 to move vertically upward along the fixed rod 5.

[0021] In this embodiment, the limiting groove 202 and the slot 303 limit the movement of the lever 404, which improves the rotational stability of the lever 404. At the same time, by rotating the lever 404, the pressing block 402 is driven to move the intermediate pressure block 301, which effectively reduces the adjustment difficulty of the intermediate pressure block 301, thereby reducing operation time and improving work efficiency. Furthermore, by locking the crossbar 405 with the two insert rods 704, it can be adjusted in advance before installation. During installation, the intermediate pressure block 301 can be pressed against the photovoltaic panel by simply sliding the two insert rods 704, which further reduces the installation difficulty and improves applicability.

[0022] Example 3 like Figure 3 and Figure 5 As shown, the extrusion assembly 4 also includes a crossbar 405, which is fixedly connected to the lever 404. One end of the crossbar 405 has an insertion hole 406 through which the crossbar 405 passes. The locking assembly 7 also includes an arc plate 702, which is fixedly installed at the bottom of the two fixed seats 701. The top of the arc plate 702 has an arc groove 703. When the rotating shaft 401 rotates at a certain angle, the lever 404 matches the arc groove 703.

[0023] In this embodiment, the crossbar 405 is limited by the arc groove 703, which makes it easier for the staff to insert the insertion rod 704 into the insertion hole 406, reducing the difficulty of positioning the crossbar 405. In addition, the insertion rod 704 is L-shaped, which makes it easier for the staff to hold the short end of the sliding insertion rod 704, further improving the installation efficiency and applicability.

[0024] Working principle: Before installation, the operator presses down on the crossbar 405. When the crossbar 405 is pressed, it drives the lever 404, the rotating shaft 401, and the pressing block 402 to rotate. As the lever 404 rotates, it disengages from the slot 303 and slides within the limiting groove 202. When the pressing block 402 rotates, it pushes the bottom of the middle pressure block 301, allowing the middle pressure block 301 to move vertically upwards under the limiting action of the guide rod 304 and the guide groove 203. As the middle pressure block 301 slides, it compresses the compression spring 502 and pulls the tension spring 501, causing both the tension spring 501 and the compression spring 502 to deform. When the rotating shaft 401 rotates, it causes the two torsion springs 403 to deform. When the crossbar 405 rotates to a certain angle and aligns with the inner wall of the arc-shaped groove 703, the operator horizontally pulls the two insertion rods 704, causing them to insert into both ends of 706 respectively. The limiting block 705 is used to limit the position, and then the rectangular clamping block 1 is installed inside the C-shaped steel. After installation, the rectangular clamping block 1 is rotated so that both ends of the rectangular clamping block 1 abut against the inner wall of the C-shaped steel. At this time, the rectangular clamping block 1 can slide inside the C-shaped steel. Then, one end of the middle pressure block 301 abuts against a photovoltaic panel, and then the other photovoltaic panel to be installed abuts against the other side of the middle pressure block 301. Finally, the two insertion rods 704 are pulled in the opposite direction so that the insertion rods 704 no longer limit the limiting block 705. At this time, the two torsion springs 403 release pressure and cause the rotating shaft 401, the pressing block 402 and the lever 404 to reverse. At the same time, the tension spring 501 and the compression spring 502 release force to apply a certain downward pressure to the middle pressure block 301, so that the middle pressure block 301 presses the top of the two photovoltaic panels after moving vertically downward, and the installation is completed quickly. When the medium pressure block 301 moves, it can synchronously drive the annular plate 302 to move. When the annular plate 302 moves, it slides in conjunction with the annular groove 601, resulting in a strong protection effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
