Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a locking and anti-loosening structure and installation method for a photovoltaic support in mountainous areas. Background Technology

[0002] With the growth of global energy demand and the improvement of environmental awareness, photovoltaic power generation has been widely used as a clean and renewable energy source. Photovoltaic power generation mainly consists of three parts: solar panels (modules), controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. Mountainous and hilly areas are the main installation areas for photovoltaic power generation equipment.

[0003] In practical applications, due to the complex surfaces of mountainous and hilly terrains, existing flat-ground photovoltaic installation brackets cannot effectively adapt to these surfaces. It is necessary to weld installation brackets on-site to accommodate the undulating terrain, resulting in low installation efficiency. To address this issue, Chinese Patent Publication No. CN223859095U discloses "A Photovoltaic Bracket Adapted to Mountainous Slopes." This bracket, after fixing the support rod to the mountain surface, rotates the first adjusting block to push the support screw upwards, adjusting four sets of fixing plates to the same horizontal plane. This facilitates the rapid installation and fixing of the support beam and mounting plates, making it adaptable to different mountainous and hilly surfaces and effectively improving photovoltaic panel installation efficiency.

[0004] However, in actual use, when clamping and fixing photovoltaic modules, conventional bolt fastening or simple clipping methods are used. Due to the complex environment of mountainous terrain, the modules are easily loosened by vibration, which can lead to the photovoltaic modules not being firmly fixed, shifting or falling off. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing photovoltaic module clamping and fixing structures, such as susceptibility to vibration and loosening in complex mountainous environments, poor locking reliability, and high maintenance costs. This invention proposes a locking and anti-loosening structure and installation method for mountain photovoltaic brackets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A locking and anti-loosening structure for a mountain photovoltaic support is designed, including a mounting plate and limiting components. A driving component is provided on the mounting plate, and the driving component is poweredly connected to multiple limiting components. A positioning component is provided on the mounting plate. One side of the mounting plate is connected to the support frame, the support frame is provided with a positioning plate, and the positioning plate is equipped with a fixing component that cooperates with the drive component.

[0007] Furthermore, the driving component includes: A drive ring is rotatably mounted on the mounting plate. The mounting plate is fixedly provided with multiple anti-detachment parts, all of which are slidably connected to the drive ring.

[0008] Furthermore, the driving component also includes An L-shaped plate is disposed on the mounting plate, and an clearance groove is provided on the mounting plate to cooperate with the L-shaped plate. One end of the L-shaped plate passes through the clearance groove and is fixedly connected to the limiting member.

[0009] Furthermore, each of the L-shaped plates is fixedly provided with a drive column, and the drive ring is provided with multiple guide arc-shaped grooves, and the drive column is movably inserted into the arc-shaped grooves.

[0010] Furthermore, the positioning component includes: A positioning ring is fixedly mounted on the drive ring, and the mounting plate is provided with a positioning structure that cooperates with the positioning ring in a one-way limiting manner.

[0011] Furthermore, the positioning structure includes: A guide frame is fixedly mounted on the mounting plate, and a positioning block is movably inserted into the guide frame. The positioning block is connected to the guide frame through an elastic element.

[0012] Furthermore, one end of the positioning block extends out of the guide frame and contacts the positioning ring; The positioning ring has a circumferential array of ratchet teeth, and the positioning block has a plug-in part corresponding to the ratchet teeth.

[0013] Furthermore, the fixing component includes: The positioning pin mechanism is installed on the positioning plate, and the drive ring has an initial groove and a termination groove. The positioning pin mechanism includes a sleeve, and a positioning pin that cooperates with the initial groove and the termination groove is connected inside the sleeve by a spring.

[0014] Furthermore, a slot is formed on the sleeve, a threaded post is fixedly connected to the positioning pin, and a wing nut is threaded onto the threaded post.

[0015] The present invention also proposes an installation method for a mountain photovoltaic support structure, including the above-mentioned locking and anti-loosening structure, and further including the following steps: S1. First, connect the mounting plate to the pre-embedded support frame, and adjust the angle of the mounting plate by connecting it to the purchased support frame; S2. Loosen the wing nut, move the threaded post and the locating pin to separate the locating pin from the initial groove, and rotate the drive ring to make the initial groove and the locating pin misalign. S3. Place the photovoltaic module on the mounting plate, rotate the drive ring to move multiple limiting parts simultaneously, clamp and fix the photovoltaic module. During this process, the positioning structure limits the drive ring in one direction to prevent the limiting parts and the drive ring from moving in opposite directions. S4. When the drive ring rotates to the point where the positioning pin corresponds to the termination groove, that is, when the limiting component fully clamps the photovoltaic module, the spring drives the positioning pin to insert into the termination groove to fix the drive ring. At the same time, the wing nut is tightened to fix the positioning pin and prevent the drive ring from loosening.

[0016] The invention proposes a locking and anti-loosening structure and installation method for mountain photovoltaic supports, which has the following advantages: In this invention, by rotating the drive ring, the arc groove on the drive ring cooperates with the drive columns on multiple L-shaped plates to convert the rotational motion into the linear translational motion of multiple limiting components. Only one person needs to operate once to drive multiple limiting components to extend simultaneously to clamp and fix the photovoltaic module, thereby improving the installation efficiency of photovoltaic panels in mountainous environments and ensuring that the photovoltaic module is subjected to uniform clamping force around its perimeter. Secondly, in this invention, during the process of the rotating drive ring clamping the photovoltaic module, the one-way limiting structure composed of the positioning ring, ratchet, positioning block and elastic element allows the drive ring to rotate in the forward direction to push the limiting element throughout the entire clamping drive process, preventing the photovoltaic module from loosening midway and reducing the installation difficulty. Furthermore, in this invention, the drive ring is limited to its initial and final states by a spring-driven positioning pin, thereby locking the drive ring and preventing it from rotating accidentally before installation or loosening after installation. Finally, the drive ring is locked by the threaded tightening structure of the threaded column and the wing nut. The entire installation process basically does not require the use of installation tools, making it suitable for harsh mountain environments without electricity. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1-7 A locking and anti-loosening structure for a mountain photovoltaic support includes a mounting plate 1 and a limiting member 2. The limiting member 2 has an L-shaped cross-section, which can limit and prevent the photovoltaic module frame from falling off. A driving component 3 is provided on the mounting plate 1. The driving component 3 is poweredly connected to multiple limiting members 2. A positioning component 4 is provided on the mounting plate 1. One side of the mounting plate 1 is connected to the support frame 6, the support frame 6 is provided with a positioning plate 7, and the positioning plate 7 is equipped with a fixing component 8 that cooperates with the drive component 3.

[0021] In this invention, the driving component 3 enables the synchronous linkage clamping of multiple limiting components 2, thereby fixing the photovoltaic module in multiple directions; the positioning component 4 provides unidirectional limiting to prevent backing during the clamping process; the fixing component 8 cooperates with the positioning plate 7 to lock the initial standby state and the final clamping state of the driving component 3, preventing accidental activation of the driving component 3, and also solving the problem of easy loosening after installation of photovoltaic systems in mountainous areas.

[0022] Furthermore, in this embodiment, the driving component 3 includes: A drive ring 31 is rotatably mounted on the mounting plate 1. The mounting plate 1 is fixedly provided with a plurality of anti-detachment parts 32. The anti-detachment parts 32 are all slidably connected to the drive ring 31. The anti-detachment parts 32 play a radial and axial limiting role for the drive ring 31, ensuring that the drive ring 31 maintains a stable track when subjected to rotational force and will not detach from the mounting plate 1. In some embodiments, a handle is installed on the drive ring 31 to facilitate the application of force.

[0023] Specifically, in this embodiment, the driving component 3 further includes An L-shaped plate 33 is disposed on the mounting plate 1. The mounting plate 1 has a clearance groove 34 that cooperates with the L-shaped plate 33. One end of the L-shaped plate 33 passes through the clearance groove 34 and is fixedly connected to the limiting member 2. The clearance groove 34 provides a linear guide for the translational movement of the L-shaped plate 33, so that the L-shaped plate 33 can only slide along the radial direction of the clearance groove 34, avoiding deflection when subjected to force, thereby ensuring the stability of the limiting member 2 in clamping the photovoltaic module.

[0024] Furthermore, in this embodiment, each of the L-shaped plates 33 is fixedly provided with a drive column 35, and the drive ring 31 is provided with multiple guide arc-shaped grooves 36. The drive column 35 is movably inserted into the arc-shaped grooves 36. When the drive ring 31 is rotated, the inner wall of the arc-shaped groove 36 squeezes the drive column 35, converting the rotational motion of the drive ring 31 into the linear translational motion of the L-shaped plate 33. Only one person needs to operate the drive ring 31 once to drive multiple limiting members 2 to extend simultaneously to clamp and fix the photovoltaic module, ensuring that the photovoltaic module is subjected to a uniform clamping force around it. Preferably, before fixing the photovoltaic module, it is best to adjust the mounting plate 1 to be horizontal with the ground to prevent the photovoltaic module from falling off.

[0025] It should be noted that, in this embodiment, the positioning component 4 includes: A positioning ring 41 is fixedly mounted on the drive ring 31. The mounting plate 1 is provided with a positioning structure 42 that cooperates with the positioning ring 41 in a one-way limiting manner. The positioning ring 41 rotates synchronously with the drive ring 31. Through the one-way limiting cooperation of the positioning structure 42, the drive ring 31 is only allowed to rotate in the forward direction during the clamping process to push the limiting member 2, thereby achieving anti-loosening during clamping.

[0026] Specifically, in this embodiment, the positioning structure 42 includes: A guide frame 421 is fixedly mounted on the mounting plate 1. A positioning block 422 is movably inserted into the guide frame 421. The positioning block 422 is connected to the guide frame 421 through an elastic element 425.

[0027] One end of the positioning block 422 extends out of the guide frame 421 and contacts the positioning ring 41; The positioning ring 41 has a circumferential array of ratchet teeth 423, and the positioning block 422 has a corresponding insertion part 424. The guide frame 421 provides sliding guidance for the positioning block 422, while the elastic element 425 continuously provides the positioning block 422 with a pushing force towards the positioning ring 41, ensuring that the positioning block 422 can always be in close contact with the positioning ring 41. When the drive ring 31 rotates clockwise, the inclined surface of the ratchet teeth 423 smoothly slides over the insertion part 424, and the elastic element 425 is compressed. When the drive ring 31 has a tendency to rotate counterclockwise, the insertion part 424 directly abuts against the right angle surface of the ratchet teeth 423 and is blocked, thereby locking the counterclockwise path.

[0028] Furthermore, in this embodiment, the fixing component 8 includes: The positioning pin mechanism 81 is installed on the positioning plate 7, and the drive ring 31 is provided with an initial groove 82 and a termination groove 83. The positioning pin mechanism 81 includes a sleeve 811, and a positioning pin 813 that cooperates with the initial groove 82 and the termination groove 83 is connected inside the sleeve 811 by a spring 812. Before installation, the spring 812 drives the positioning pin 813 to insert into the initial groove 82 to prevent the drive ring 31 from rotating accidentally before transportation or installation. When clamped in place, the positioning pin 813 automatically springs into the termination groove 83 under the action of the spring 812 to realize the mechanical limit of the drive ring 31 and prevent it from loosening due to vibration.

[0029] More specifically, in this embodiment, a slot 814 is formed on the sleeve 811, and a threaded post 815 is fixedly connected to the positioning pin 813. A wing nut 816 is threadedly connected to the threaded post 815. When the positioning pin 813 is inserted into the termination slot 83, the wing nut 816 is tightened, and the self-locking characteristic of the threaded tightening structure is used to completely press the positioning pin 813 into the sleeve 811, forming a rigid anti-loosening deadlock. The wing nut 816 can be operated completely by hand, basically without the need for wrenches or other installation tools, perfectly adapting to the harsh environment of mountainous areas without electricity and inconvenient transportation.

[0030] The present invention also proposes an installation method for a mountain photovoltaic support structure, including the above-mentioned locking and anti-loosening structure, and further including the following steps: S1. First, connect the mounting plate 1 to the pre-embedded support frame 6, and adjust the angle of the mounting plate 1 by connecting it to the pre-embedded support frame 6. S2. Loosen the wing nut 816, move the threaded post 815 and the locating pin 813 to separate the locating pin 813 from the initial groove 82, and rotate the drive ring 31 to make the initial groove 82 and the locating pin 813 misaligned. S3. Place the photovoltaic module on the mounting plate 1, rotate the drive ring 31 to move multiple limiting parts 2 at the same time, clamp and fix the photovoltaic module. During this process, the positioning structure 42 limits the drive ring 31 in one direction to prevent the limiting parts 2 and the drive ring 31 from moving in opposite directions. S4. When the drive ring 31 rotates to the point where the positioning pin 813 corresponds to the termination groove 83, that is, when the limiting member 2 fully clamps the photovoltaic module, the spring 812 drives the positioning pin 813 to insert into the termination groove 83 to fix the drive ring 31. At the same time, the wing nut 816 is tightened to fix the positioning pin 813 and prevent the drive ring 31 from loosening.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
