Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and more specifically, to a photovoltaic bracket that facilitates fixing photovoltaic panels. Background Technology

[0002] A photovoltaic (PV) panel is a power generation device that directly converts sunlight into direct current (DC). Its core component is a photovoltaic cell made of semiconductor materials, which generates current through the photovoltaic effect. When using PV panels, a PV support system is often needed for support and fixation. For example, application number "CN202411052775.3" proposes a PV support system comprising: a load-bearing module for fixed connection to a wall; a support module for installing the PV panel, the support module having at least three connecting parts; and a transition module including a first connecting part and a second connecting part. Two connecting parts; the first connecting part includes a rotating rod, one end of which is rotatably connected to the load-bearing module, and the other end of which is rotatably connected to the first connecting part; the second connecting part is fixedly connected to the load-bearing module, and can be detachably connected to the second connecting part or the third connecting part; when the second connecting part is detachably connected to the second connecting part, the distance between the first connecting part and the load-bearing module is a first distance, and when the second connecting part is detachably connected to the third connecting part, the distance between the first connecting part and the load-bearing module is a second distance, and the first distance is greater than the second distance;

[0003] However, in the above-mentioned technical solutions, the installation of photovoltaic panels requires not only aligning each screw hole and tightening the bolts one by one, which is a complicated process, but also the bolts are prone to rusting due to environmental corrosion after long-term use. This makes the disassembly process very difficult when replacing photovoltaic panels later, often requiring the use of tools to forcibly disassemble them, which is time-consuming, laborious, and may also damage the bracket body. Therefore, we propose a photovoltaic bracket that is easy to fix photovoltaic panels to solve the above problems. Utility Model Content

[0028] like Figures 4 to 10As shown, in another embodiment of this utility model, connecting frames 6 are bolted to the front and rear ends of the lower surface of the vertical beam 1. Columns 5 are movably installed inside the connecting frames 6, and fixing rods 7 are installed inside the connecting frames 6, with the rods of the fixing rods 7 movably penetrating inside the columns 5. Second engaging blocks 14 are installed at both ends of the lower surface of the cover plate 11, and second engaging grooves 13 are provided at both ends of the upper surface of the crossbeam 2.

A knob block 317 is respectively installed on the opposite ends of the transmission rod 315. The surfaces of the knob block 317 and the movable block 302 are in contact. On the side of the movable block 302 near the knob block 317, a number of second positioning holes 319 are arranged in a circle around the axis of the rotating shaft 310. A number of second positioning rods 318 are arranged in a circle around the side of the knob block 317 near the movable block 302. The second positioning rods 318 are engaged and installed inside the second positioning holes 319.

[0029] The user connects the connecting frame 6 and the vertical beam 1 with bolts. Then, the user arranges the vertical beams 1 according to the number of photovoltaic panels 4 to be installed. The user then removes the horizontal beam 2. After removing the horizontal beam 2, the user installs the second threaded rod 10 on the slider 9 into the through hole 12 of the horizontal beam 2 according to the spacing between each vertical beam 1, and installs the nut by thread. The user then inserts the slider 9 into the slide groove 8 to complete the installation of the horizontal beam 2. After the position of the horizontal beam 2 is adjusted, the user rotates the nut to allow the slider 9 to clamp and fix the vertical beam 1 and the horizontal beam 2 with the nut. After the bracket is completed, the user places the movable block 302 at the lower end of the horizontal beam 2 and inserts the first threaded rod 303 at the upper end of the movable block 302 into the through hole 12 in the horizontal beam 2. The user then fixes the first threaded rod 303 with bolts to complete the installation of the movable block 302.

[0030] The user can then place the photovoltaic panel body 4 into the frame constructed by the vertical beams 1 and the horizontal beams 2. The parallel arrangement of the vertical beams 1 and the upper and lower limits of the horizontal beams 2 provide basic support space for the photovoltaic panel. After the photovoltaic panel is installed, the user can place the cover plate 11 and then install the fixing frame 301. The lower end of the fixing frame 301 is inserted into the through hole 12 that coincides with the cover plate 11 and the horizontal beam 2, so that the fixing frame 301 is in contact with the upper surface and both sides of the photovoltaic panel body 4. The user can then insert the first locking block 305 into the first locking groove 304 of the fixing frame 301, and at the same time, the first positioning rod 307 is inserted into the first positioning hole 306. After the first locking block 305 and the first positioning rod 307 are installed, the user can first pull the knob block 317 outward. The knob block 317 drives the second positioning rod 318 out of the second positioning hole 319, and at the same time drives the transmission rod 315 and the turntable 313 to move outward, so that the turntable 313 squeezes the spring 316. Then, the user can control the rotating shaft 310 and the winding rod 311 to start winding the pull rope 308 through the knob block 317 and the turntable 313 in conjunction with the guide rod 314. Then, the pull rope 308 pulls the fixing frame 301 through the first locking block 305, and finally achieves the clamping and fixing of the photovoltaic panel body 4. Then, the user can push the knob block 317 to reset, and at the same time, the spring 316 will also push the turntable 313 and the transmission rod 315 to reset, so that the knob block 317 drives the second positioning rod 318 to insert into the second positioning hole 319 again, realizing the positioning of the rotating shaft 310.

[0031] Then, when it is necessary to replace the photovoltaic panel body 4, simply pull the knob block 317 outward again, and then reverse the knob block 317 to loosen the pull rope 308. After the tension of the pull rope 308 disappears, the user can take out the first locking block 305 and the fixing bracket 301, and then take out the photovoltaic panel body 4 for replacement.

[0032] The working principle of this photovoltaic bracket that facilitates fixing photovoltaic panels:

[0033] In use, the user first connects the connecting frame 6 and the vertical beam 1 with bolts. Then, the user arranges the vertical beams 1 according to the number of photovoltaic panels 4 to be installed. Then, the user takes out the horizontal beam 2. After the horizontal beam 2 is taken out, the user installs the second threaded rod 10 on the slider 9 into the through hole 12 of the horizontal beam 2 according to the spacing between each vertical beam 1, and installs the nut with the thread. Then, the user can insert the slider 9 into the inside of the slide groove 8 to realize the installation of the horizontal beam 2. After the position of the horizontal beam 2 is adjusted, the user can rotate the nut to make the slider 9 cooperate with the nut to clamp and fix the vertical beam 1 and the horizontal beam 2. After the bracket is completed, the user places the movable block 302 at the lower end of the horizontal beam 2 and inserts the first threaded rod 303 at the upper end of the movable block 302 into the through hole 12 in the horizontal beam 2. Then, the user fixes the first threaded rod 303 with bolts to complete the installation of the movable block 302.

[0034] The user can then place the photovoltaic panel body 4 into the frame constructed by the vertical beams 1 and the horizontal beams 2. The parallel arrangement of the vertical beams 1 and the upper and lower limits of the horizontal beams 2 provide basic support space for the photovoltaic panel. After the photovoltaic panel is installed, the user can place the cover plate 11 and then install the fixing frame 301. The lower end of the fixing frame 301 is inserted into the through hole 12 that coincides with the cover plate 11 and the horizontal beam 2, so that the fixing frame 301 is in contact with the upper surface and both sides of the photovoltaic panel body 4. The user can then insert the first locking block 305 into the first locking groove 304 of the fixing frame 301, and at the same time, the first positioning rod 307 is inserted into the first positioning hole 306. After the first locking block 305 and the first positioning rod 307 are installed, the user can first pull the knob block 317 outward. The knob block 317 drives the second positioning rod 318 out of the second positioning hole 319, and at the same time drives the transmission rod 315 and the turntable 313 to move outward, so that the turntable 313 squeezes the spring 316. Then, the user can control the rotating shaft 310 and the winding rod 311 to start winding the pull rope 308 through the knob block 317 and the turntable 313 in conjunction with the guide rod 314. Then, the pull rope 308 pulls the fixing frame 301 through the first locking block 305, and finally achieves the clamping and fixing of the photovoltaic panel body 4. Then, the user can push the knob block 317 to reset, and at the same time, the spring 316 will also push the turntable 313 and the transmission rod 315 to reset, so that the knob block 317 drives the second positioning rod 318 to insert into the second positioning hole 319 again, realizing the positioning of the rotating shaft 310.

[0035] Then, when it is necessary to replace the photovoltaic panel body 4, simply pull the knob block 317 outward again, and then reverse the knob block 317 to loosen the pull rope 308. After the tension of the pull rope 308 disappears, the user can take out the first locking block 305 and the fixing bracket 301, and then take out the photovoltaic panel body 4 for replacement.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
