[0002] As an important component of clean energy, photovoltaic power generation systems play a crucial role in the global energy structure transformation. Their installation scale and application scope continue to expand. As the supporting structure of the entire power generation system, the photovoltaic panel mounting bracket not only undertakes the functions of fixing the components and transferring loads, but also directly affects the system's wind and earthquake resistance, component heat dissipation efficiency, and long-term operational reliability. The rational design of the bracket can effectively reduce the mechanical stress of the photovoltaic panels, reduce power generation efficiency loss, and extend the service life of the system. It is a key link in ensuring the safe and stable operation of photovoltaic power plants.

This necessitates overall system adjustments when replacing or upgrading PV modules, increasing construction and maintenance costs. Furthermore, PV panels are susceptible to wind vibration, mechanical vibration, and external impacts during operation. Prolonged vibration can lead to loose bolts, structural fatigue, and even module damage, affecting system safety and power generation efficiency. Utility Model Content

[0026] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0027] Figures 1-6In one embodiment of this utility model, a photovoltaic panel mounting bracket includes a base 1 and a mounting frame 2 located above the base 1. The mounting frame 2 is provided with a clamping mechanism 4, and the base 1 is provided with a vibration damping and protection mechanism 3. The clamping mechanism 4 includes two sets of mounting rods 401 vertically distributed on the mounting frame 2. Two sets of symmetrically distributed telescopic rods 402 are slidably installed in the mounting rods 401. Clamping rods 403 are slidably installed in both sets of telescopic rods 402. A bidirectional screw is rotatably installed in the mounting rods 401. 404. A screw tube 406 is rotatably installed inside each of the two sets of telescopic rods 402. A first bevel gear 415408 is sleeved on the bidirectional screw 404. A second bevel gear 415409 is provided inside the mounting rod 401, and the second bevel gear 415409 meshes with the first bevel gear 415408. The second bevel gear 415409 is rotatably connected to the mounting rod 401 via a handle 410. Two sets of symmetrically distributed ratchet wheels 411 are sleeved on the handle 410. Two sets of ratchet wheels 411 are provided inside the mounting rod 401. The ratchet 411 and the corresponding pawl 412, through the coordinated design of the clamping mechanism 4 and the vibration damping protection mechanism 3, effectively solve the problems of poor adaptability and insufficient vibration resistance of the traditional photovoltaic bracket 301. The clamping mechanism 4 adopts a linkage structure of driving the telescopic rod 402 and the clamping rod 403 with the bidirectional screw 404. With the self-locking mechanism of the ratchet 411 and pawl 412, it can realize the quick clamping and fixing of photovoltaic panels of different sizes, which significantly improves the versatility and installation efficiency of the bracket 301. The vibration damping protection mechanism 3, through the combination of the cross bracket 301 and the spring damping system, converts vertical vibration into horizontal sliding of the slider 302. By using the bidirectional first spring 304, the second spring 306 for reset and the damping energy dissipation of the damping rod 305, the impact of wind vibration and mechanical impact on the photovoltaic panel is greatly reduced. This design not only ensures the structural stability of the mounting bracket 2, but also extends the life of the photovoltaic module through multi-level buffering, while simplifying the maintenance process and reducing the total life cycle cost, which has significant practical value and economic benefits.
[0028] In this embodiment, reference Figure 4 , Figure 5 , Figure 6As shown, the two ends of the bidirectional screw 404 pass through two sets of telescopic rods 402 and are threadedly connected to the two sets of telescopic rods 402 respectively. The two sets of screw tubes 406 pass through two sets of corresponding clamping rods 403 and are threadedly connected to the corresponding clamping rods 403 respectively. The bidirectional screw 404 has two sets of symmetrically distributed keyways 405. Each of the two sets of screw tubes 406 has two sets of symmetrically distributed key blocks 407, with the key blocks 407 corresponding to the keyways 405. Both sets of screw tubes 406 slide against the bidirectional screw 404 through the key blocks 407 and the keyways 405. The two sets of ratchet pawls 412 are rotatably connected to the mounting rod 401 via a rotating rod. A torsion spring 414 is sleeved on the rotating rod, and both ends of the torsion spring 414 are fixedly connected to the ratchet pawl 412 and the mounting rod 401, respectively. A gear 415 is sleeved on the rotating rod. A rack 416 is slidably installed inside the mounting rod 401, and the rack 416 meshes with the gear 415. A pull bracket 417 is slidably installed inside the mounting rod 401, and the pull bracket 417 is fixedly connected to the two sets of racks 416. Two sets of pull brackets 417 are fixedly installed inside the mounting rod 401. The corresponding fixed rods 418 and the pull brackets 417 are slidably sleeved with the two sets of fixed rods 418 respectively. Two sets of symmetrically distributed third springs 419 are sleeved on the fixed rods 418. The two ends of the third springs 419 are fixedly connected to the pull brackets 417 and the mounting rods 401 respectively. The clamping mechanism 4 drives the second bevel gear 415409 to mesh with the first bevel gear 415408 by rotating the handle 410, thereby driving the bidirectional screw 404 to rotate synchronously. Since the bidirectional screw 404 adopts a reverse thread design at both ends, its rotation is achieved by pushing through the thread engagement. The two sets of telescopic rods 402 slide synchronously towards or away from each other along the mounting rod 401. At the same time, the bidirectional screw 404 drives the two sets of screw tubes 406 to rotate synchronously through the keyway 405 and the key block 407. The screw tubes 406 then drive the clamping rod 403 to move axially along the telescopic rod 402 through the threaded transmission, thereby realizing four-way synchronous clamping of photovoltaic panels of different sizes. The ratchet 411 and pawl 412 mechanism engages with the bidirectional ratchet 411 through the pre-tightened pawl 412 of the torsion spring 414, forming a self-locking at any stop position to prevent reverse loosening.
[0029] In this embodiment, reference Figure 2 and Figure 3As shown, the vibration damping protection mechanism 3 includes two sets of cross-distributed brackets 301 between the base 1 and the mounting frame 2. The upper ends of both sets of brackets 301 are rotatably connected to the mounting frame 2 via rotating shafts. The lower ends of both sets of brackets 301 are rotatably mounted with sliders 302, which are slidably connected to the base 1. A damping rod 305 is fixedly installed between the slider 302 and the base 1, and a second spring 306 is fitted on the damping rod 305. A sliding rod 303 is fixedly installed inside the base 1, and the slider 302 is slidably sleeved with the sliding rod 303. Two sets of symmetrically distributed first springs 304 are sleeved on the sliding rod 303. Both ends are fixedly connected to the slider 302 and the base 1 respectively. When the vibration damping protection mechanism 3 is working, the external vibration is transmitted to the cross bracket 301 through the mounting bracket 2, which forces the bracket 301 to change its included angle and pushes the slider 302 to slide horizontally along the slide rod 303. At this time, the first spring 304 provides primary buffering, and the second spring 306 in the damping rod 305 performs secondary vibration damping. At the same time, the damping medium converts kinetic energy into heat energy dissipation, forming a three-level energy dissipation system. This linkage mechanism converts vertical vibration into horizontal reciprocating motion, and achieves multi-dimensional vibration damping through spring reset and damping energy dissipation, ultimately ensuring the stable operation of the photovoltaic panel under dynamic load.
[0030] In this embodiment, during operation, the clamping mechanism 4 drives the second bevel gear 415409 to mesh with the first bevel gear 415408 by rotating the handle 410, thereby driving the bidirectional screw 404 to rotate synchronously. Since the bidirectional screw 404 has reverse threads at both ends, its rotation pushes the two sets of telescopic rods 402 to slide synchronously towards or away from each other along the mounting rod 401 via threaded engagement. Simultaneously, the bidirectional screw 404 drives the two sets of screw tubes 406 to rotate synchronously via the keyway 405 and key block 407. The screw tubes 406 then cause the clamping rod 403 to move axially along the telescopic rod 402 via threaded transmission, thus achieving four-way synchronous clamping of photovoltaic panels of different sizes. Furthermore, the ratchet 411 and pawl 412 mechanism... The pawl 412, pre-tightened by the torsion spring 414, engages with the bidirectional ratchet 411, forming a self-locking mechanism at any stop position to prevent reverse loosening. When the vibration damping protection mechanism 3 is working, external vibration is transmitted to the cross bracket 301 through the mounting bracket 2, forcing the bracket 301 to change its angle and pushing the slider 302 to slide horizontally along the slide bar 303. At this time, the first spring 304 provides primary buffering, and the second spring 306 in the damping rod 305 performs secondary vibration damping. At the same time, the damping medium converts kinetic energy into heat energy dissipation, forming a three-level energy dissipation system. This linkage mechanism converts vertical vibration into horizontal reciprocating motion, and achieves multi-dimensional vibration damping through spring reset and damping energy dissipation, ultimately ensuring the stable operation of the photovoltaic panel under dynamic load.
