Description

Technical Field

[0001] This utility model relates to the field of fixing components, and in particular to a novel clamping fixing bracket. Background Technology

[0002] In the construction of photovoltaic power plants, the stable fixing of photovoltaic modules is a crucial step in ensuring power generation efficiency and system safety. During the installation of photovoltaic modules, the stability and applicability of the fixing brackets are paramount. Currently, common photovoltaic module fixing brackets mainly use clamping structures to laterally press the edges of the modules, but this method has significant drawbacks.

[0003] The clamping force is applied in a single direction:

[0004] Existing bracket clamping structures can only provide lateral (i.e., parallel to the edge of the module) clamping force, while photovoltaic modules need to withstand multi-directional loads such as wind force and thermal stress caused by temperature changes in actual working conditions. A single lateral clamping force cannot effectively restrain the vertical displacement or deformation of the module. Especially in strong winds or snow accumulation scenarios, the module is prone to loosening or even falling off due to uneven vertical force, posing a safety hazard.

[0005] Based on this, we propose a novel clamping and fixing bracket. Utility Model Content

[0006] To address the technical problem of a single clamping force direction, this utility model provides a novel clamping and fixing bracket.

[0007] This utility model is achieved by the following technical solution: a novel pressing and fixing bracket, including a linear pressing mechanism and a multi-angle pressing mechanism. The linear pressing mechanism includes a fixed crossbeam, a first bracket arm is fixedly connected to the outer surface of the fixed crossbeam, and a second bracket arm is slidably connected to the outer surface of the fixed crossbeam.

[0008] The bottom of the first support arm is provided with a first support fixing block, which is fixedly sleeved on the fixed crossbeam. The bottom of the second support arm is provided with a second support slider, which is slidably sleeved on the fixed crossbeam. The top of the first support arm is integrally formed with a fastening sleeve, and a clamping screw is threaded through the surface of the fastening sleeve. One end of the clamping screw is fixedly connected to an adjusting handle, and the other end of the clamping screw is rotatably connected to a fixed beam. The bottom end of the fixed beam is welded to the second support arm, and a fixing bolt is threaded through the surface of the fixed beam. One end of the fixing bolt is connected to a first knob.

[0009] The multi-angle clamping mechanism includes a support base, on the outer surface of which a fixed connecting arm is welded; the fixed connecting arm extends downward and upward in an integrated manner to form a lower tilting arm and an upper tilting arm; the bolt position of the fixing bolt is located between the lower tilting arm and the upper tilting arm.

[0010] Both the lower and upper tilting arms are connected to connecting brackets. Supporting crossbeams are fixedly connected to both ends of the connecting brackets. Tilting clamping bolts are threaded through the surface of the supporting crossbeams, and a second knob is connected to one end of each clamping bolt. The supporting crossbeams are fixed to both ends of the connecting brackets, and the tilting clamping bolts threaded through the supporting crossbeams at both ends are installed at an angle.

[0011] The support base is fixed below the fixed beam of the linear clamping mechanism, and a fixed connecting arm is welded to its outer side, extending downward and upward to form a lower tilting arm and an upper tilting arm, constituting a V-shaped adjustable angle frame structure. By tightening the tilting clamping bolts, the tilting clamping bolts rotate on the supporting crossbeam column, thereby pressing the tilting clamping bolts towards the photovoltaic bracket. The V-shaped structure of the upper and lower tilting arms allows the tilting clamping bolts to provide clamping force (not just lateral) inclined to the surface of the photovoltaic module. Combined with the lateral force of the linear clamping mechanism, a composite force-bearing structure of "lateral positioning + tilting clamping" is formed, effectively constraining the displacement of the module under multi-directional loads such as wind force and gravity.

[0012] As a further optimization of this utility model, the lower tilting arm and the upper tilting arm are arranged in a relatively inclined V-shape, so that the multi-angle clamping mechanism can clamp and fix objects at different angles.

[0013] As a further optimization of this utility model, after the fixed beam is adjusted to the correct position, the first knob is rotated to drive the fixing bolt to move. The fixing bolt then fixes and locks the photovoltaic bracket clamped on its inner side to ensure stable lateral clamping force.

[0014] As a further optimization of this utility model, the first bracket fixing block and the second bracket slider are connected through a clamping screw. When the adjustment handle is rotated, the clamping screw rotates synchronously, driving the fixed beam connected to the top of the clamping screw to move synchronously, adjusting the lateral position of the fixed beam, and realizing the adaptation to the lateral spacing of the photovoltaic module.

[0015] As a further optimization of this utility model, a through hole matching the clamping screw is provided on the fixed beam. The rod body of the clamping screw is installed inside the through hole through a bearing, and the clamping screw can rotate around its own axis. By rotating the adjustment handle, the clamping screw can be driven to push the fixed beam to move, thereby adjusting the clamping force.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model provides lateral positioning and pre-tightening force through a linear clamping mechanism and a clamping screw. The multi-angle clamping mechanism applies a clamping force inclined to the surface of the photovoltaic module through inclined clamping bolts installed at an angle, forming a composite force structure of "lateral constraint + inclined clamping". This avoids the problem of module warping and loosening caused by a single lateral clamping force and significantly improves the fixation stability.

[0018] 2. The linear clamping mechanism of this novel clamping and fixing bracket provides a stable lateral clamping force to the photovoltaic module through the clamping screw, effectively preventing it from moving horizontally. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example 1:

[0026] Please combine Figures 1-3 This embodiment proposes a novel clamping and fixing bracket, including a linear clamping mechanism 1 and a multi-angle clamping mechanism 2. The linear clamping mechanism 1 includes a fixed crossbeam 10, a first bracket arm 11 is fixedly connected to the outer surface of the fixed crossbeam 10, and a second bracket arm 12 is slidably connected to the outer surface of the fixed crossbeam 10.

[0027] The bottom of the first support arm 11 is provided with a first support fixing block 13, which is fixedly sleeved on the fixed crossbeam 10. The bottom of the second support arm 12 is provided with a second support slider 14, which is slidably sleeved on the fixed crossbeam 10. The top of the first support arm 11 is integrally formed with a fastening sleeve 17. The surface of the fastening sleeve 17 is threaded through a clamping screw 15. One end of the clamping screw 15 is fixedly connected to an adjusting handle 16, and the other end of the clamping screw 15 is rotatably connected to a fixing beam 18. The bottom end of the fixing beam 18 is welded to the second support arm 12. The surface of the fixing beam 18 is threaded through a fixing bolt 19, and one end of the fixing bolt 19 is connected to a first knob 110.

[0028] In a further specific embodiment, the fixed beam 18 has a through hole that matches the clamping screw 15. The rod of the clamping screw 15 is installed inside the through hole through a bearing, and the clamping screw 15 can rotate around its own axis. By rotating the adjusting handle 16, the clamping screw 15 can be driven to push the fixed beam 18 to move, thereby adjusting the clamping force.

[0029] In the specific technical solution, the first bracket fixing block 13 and the second bracket slider 14 are connected through a clamping screw 15. When the adjusting handle 16 is rotated, the clamping screw 15 rotates synchronously, driving the fixing beam 18 connected to the top of the clamping screw 15 to move synchronously, adjusting the lateral position of the fixing beam 18, and realizing the adaptation to the lateral spacing of the photovoltaic module.

[0030] More specifically, after the fixed beam 18 is positioned, the first knob 110 is rotated to drive the fixing bolt 19 to move. The fixing bolt 19 then fixes and locks the photovoltaic bracket clamped inside it, ensuring stable lateral clamping force.

[0031] The multi-angle clamping mechanism 2 includes a support base 21, and a fixed connecting arm 22 is welded to the outer surface of the support base 21; the fixed connecting arm 22 extends downward and upward in an integrated manner to form a downward tilting arm 23 and an upward tilting arm 24.

[0032] The technical solution that needs to be explained is that the bolt position of the fixing bolt 19 is located between the lower tilting arm 23 and the upper tilting arm 24.

[0033] Both the lower tilting arm 23 and the upper tilting arm 24 are connected to connecting brackets 25. Supporting crossbeams 26 are fixedly connected to both ends of the connecting brackets 25. Inclined clamping bolts 27 are threaded through the surface of the supporting crossbeams 26, and a second knob 28 is connected to one end of each inclined clamping bolt 27. The supporting crossbeams 26 are fixed to both ends of the connecting brackets 25, and the inclined clamping bolts 27 threaded through the supporting crossbeams 26 are installed at an angle.

[0034] In a further technical solution, the lower tilting arm 23 and the upper tilting arm 24 are arranged in a relatively inclined V-shape, so that the multi-angle clamping mechanism 2 can clamp and fix objects at different angles.

[0035] More specifically, the support base 21 is fixed below the fixed beam 18 of the linear clamping mechanism 1, and a fixed connecting arm 22 is welded to its outer side, extending downward and upward to form a lower tilting arm 23 and an upper tilting arm 24, constituting a V-shaped adjustable angle frame structure. By tightening the tilting clamping bolt 27, the tilting clamping bolt 27 rotates on the supporting crossbeam column 26, thereby pressing the tilting clamping bolt 27 towards the photovoltaic bracket. The V-shaped structure of the upper and lower tilting arms allows the tilting clamping bolt 27 to provide a clamping force (not just lateral) inclined to the surface of the photovoltaic module. Combined with the lateral force of the linear clamping mechanism 1, a composite force-bearing structure of "lateral positioning + tilting clamping" is formed, effectively constraining the displacement of the module under multi-directional loads such as wind force and gravity.

[0036] This patent achieves lateral positioning and multi-directional clamping of photovoltaic modules through the modular cooperation of a linear clamping mechanism 1 and a multi-angle clamping mechanism 2. The linear clamping mechanism provides pre-tension in the horizontal direction, while the multi-angle clamping mechanism provides clamping force and angle adaptation when tilted to the module surface. The combination of the two solves the problem of "single lateral force" in traditional brackets. The specific working principle is as follows:

[0037] Working principle of linear clamping mechanism:

[0038] Basic positioning and lateral adjustment

[0039] The first bracket fixing block 13 and the second bracket slider 14 are connected by a clamping screw 15. When the adjusting handle 16 is rotated, the clamping screw 15 rotates synchronously, driving the fixing beam 18 connected to the top of the clamping screw 15 to move synchronously, adjusting the lateral position of the fixing beam 18 to adapt to the lateral spacing of the photovoltaic modules. After the fixing beam 18 is adjusted to the correct position, the first knob 110 is rotated to drive the fixing bolt 19 to move. The fixing bolt 19 then fixes and locks the photovoltaic bracket clamped inside it, ensuring stable lateral clamping force.

[0040] Working principle of multi-angle clamping mechanism

[0041] Tilt angle adjustment

[0042] The support base 21 is fixed below the fixed beam 18 of the linear clamping mechanism 1. A fixed connecting arm 22 is welded to its outer side, extending downward and upward to form a lower tilting arm 23 and an upper tilting arm 24, forming a V-shaped adjustable angle frame structure. By tightening the tilting clamping bolt 27, the tilting clamping bolt 27 rotates on the supporting crossbeam column 26, thereby pressing the tilting clamping bolt 27 towards the photovoltaic bracket. The V-shaped structure of the upper and lower tilting arms allows the tilting clamping bolt 27 to provide a clamping force (not just lateral) inclined to the surface of the photovoltaic module. Combined with the lateral force of the linear clamping mechanism 1, a composite force structure of "lateral positioning + tilting clamping" is formed, effectively constraining the displacement of the module under multi-directional loads such as wind and gravity.
