Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a wear-resistant cable fixing clip for photovoltaic power stations. Background Technology

[0002] As the global energy structure transitions towards a low-carbon model, photovoltaic power generation has become an important part of the energy system due to its cleanliness and sustainability. The large-scale construction and long-term operation of photovoltaic power plants have placed higher demands on the reliability and maintenance efficiency of system components. Among them, cable fixing technology, as a key link to ensure the safety of power transmission, has its technological evolution directly related to the overall performance of the power plant.

[0003] An existing patent (publication number: CN208386086U) discloses a cable clamp, including two lower clamping strips and two upper clamping strips for wrapping around the cable. The upper and lower clamping strips are spaced apart and connected end-to-end to form four connecting corners. Each connecting corner has a fixing part for fixing two adjacent connecting corners at both ends of the upper clamping strip. The clamp also includes fixing strips for supporting and fixing the cable, with each end of the fixing strip connected to one of the two upper clamping strips. Fixing strips are also provided on both sides of each upper clamping strip. This invention avoids the problem of reduced service life due to the formation of a circular magnetic field path; it has a simple structure, is easy to install, and reduces construction difficulty; it can more firmly fix the cable, has strong resistance to wind loads, effectively protects the cable and auxiliary equipment, and extends its own service life.

[0004] During use, the aforementioned fixing clamp can securely fix the cable and improve wind load resistance to protect the cable and auxiliary equipment. However, during use, the cable will swing violently under the action of wind force and frequently rub against the edge of the upper clamp. Frequent friction will cause the outer sheath of the cable to wear down gradually. Once the outer sheath is damaged, the insulation layer inside the cable will be exposed, thus affecting the insulation performance of the cable. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-wear cable clamp for photovoltaic power plants, which has advantages such as reducing cable wear and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant cable fixing clip for a photovoltaic power station, including a mounting bracket, the mounting bracket having an L-shaped structure, two fixing members being provided on the side of the mounting bracket, both fixing members having a V-shaped structure and being symmetrically arranged, and both fixing members being hollowed out, one of the fixing members being connected to the mounting bracket through a buffer component, and the two fixing members being connected by bolts; Two inclined surfaces at the included angle of the two fasteners are fixedly connected with rubber plates, and each rubber plate extends out of a corresponding fastener; One of the fasteners has a support rod fixedly connected to its inclined surface. The bottom end of the support rod contacts the upper surface of the mounting bracket. An auxiliary component is fixedly connected to the upper surface of the mounting bracket, and the support rod contacts the auxiliary component.

[0007] Furthermore, the buffer assembly includes a fixed member and a movable ball connected to the side of the mounting bracket. The two movable balls are symmetrically arranged. One movable ball has a sliding cavity on its circumferential surface, and the other movable ball has a sliding rod fixedly connected to its circumferential surface. The sliding rod is slidably connected to the sliding cavity.

[0008] The above scheme, through the buffer structure design of the movable ball, sliding cavity and sliding rod, allows the movable ball to rotate flexibly at the ball joint when the fixed part is subjected to the force of the cable, while the sliding rod slides in the sliding cavity and squeezes the air inside the sliding cavity, thereby buffering the force and providing the fixed part with a multi-directional buffer space, which can effectively absorb and disperse the impact force from different directions.

[0009] Furthermore, the buffer assembly also includes a first spring that is fixedly connected between the mounting bracket and the mounting component, with both movable balls located inside the first spring.

[0010] Through the above scheme, the setting of the first spring further enhances the overall buffering performance of the buffer assembly. When the fixing part is subjected to the force of the cable, the first spring will undergo elastic deformation, absorbing and storing energy.

[0011] Furthermore, the first spring has a conical structure.

[0012] Through the above scheme, when the conical spring is subjected to pressure, the spring coils of different diameters can deform sequentially. As the pressure increases, the spring coils with larger diameters gradually participate in the deformation, further absorbing and dispersing the impact force.

[0013] Furthermore, the auxiliary component includes a fixed frame fixedly connected to the upper surface of the mounting bracket, a swing plate slidably connected inside the fixed frame, the bottom end of the support rod contacting the side of the swing plate, a connecting rod hinged to the side of the swing plate, the connecting rod slidably inserted into the central area of ​​the fixed frame, and a second spring sleeved on the connecting rod fixedly connected between the connecting rod and the fixed frame.

[0014] The above scheme, which combines a fixed frame, a swing plate, a connecting rod, and a second spring, provides effective cushioning for the support rod. When the support rod is subjected to force from a cable or external factors, the support rod will contact the swing plate and push the swing plate to slide within the fixed frame. At the same time, the connecting rod slides in the central area of ​​the fixed frame and compresses the second spring. The elastic deformation of the second spring can absorb and dissipate the force.

[0015] Furthermore, the auxiliary component also includes two elastic metal sheets fixedly connected to the side of the swing plate. Both elastic metal sheets are arc-shaped and symmetrically arranged, and the other end of each elastic metal sheet is fixedly connected to the inner wall of the fixed frame.

[0016] The above scheme further enhances the buffering and stability performance of the auxiliary components by setting up two elastic metal sheets. The elastic metal sheets are arc-shaped and symmetrically arranged. When the swing plate is subjected to a force and swings, the elastic metal sheets will undergo elastic deformation, absorb some energy, and reduce the swing amplitude of the swing plate.

[0017] Furthermore, there are gaps between the swing plate and the inner wall of the fixed frame on both sides along its length.

[0018] The above scheme, with its adjustable gap, allows the swing plate to swing more freely when subjected to force, without being restricted by the inner wall of the fixed frame.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This wear-resistant cable clamp for photovoltaic power stations utilizes a V-shaped fastener made of elastic metal. When clamping the cable, it undergoes slight deformation, providing a stable clamping force to prevent cable loosening while also creating a flexible contact to avoid damage to the cable sheath and internal conductors due to excessive rigid compression. Extended rubber plates at the clamping angles ensure constant contact with the cable during its swing, effectively isolating the cable from direct collisions and friction with the metal fastener's edge. Furthermore, the combined design of buffer and auxiliary components effectively absorbs and disperses impact forces and vibrations from different directions, reducing mechanical stress transmitted to the cable. By buffering the cable's swing, it protects the cable. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figures 1-6 The wear-resistant cable fixing clip for photovoltaic power stations in this embodiment includes a mounting bracket 1. The mounting bracket 1 has an L-shaped structure. Two fixing parts 2 are provided on the side of the mounting bracket 1. Both fixing parts 2 have a V-shaped structure and are symmetrically arranged. Both fixing parts 2 are hollowed out. One of the fixing parts 2 is connected to the mounting bracket 1 through a buffer component 3. The two fixing parts 2 are connected by bolts.

[0024] Rubber plates 4 are fixedly connected to the two inclined surfaces at the included angle of the two fixing parts 2. Each rubber plate 4 extends out a corresponding fixing part 2. The two fixing parts 2 are made of elastic metal. When the two fixing parts 2 clamp the cable, they can produce slight deformation, achieving a stable and flexible clamping of the cable. This ensures the clamping force to prevent the cable from loosening and avoids damage to the cable due to excessive compression. At the same time, the fixing parts 2 extending from the rubber plate 4 can keep the rubber plate 4 in contact with the cable during the cable swinging process, preventing the cable from directly colliding with the edge of the fixing part 2 and causing friction during the cable swinging process. This avoids wear on the cable sheath and damage to the internal conductors, effectively extending the service life of the cable.

[0025] One of the fasteners 2 has a support rod 5 fixedly connected to its inclined surface. The bottom end of the support rod 5 contacts the upper surface of the mounting bracket 1. An auxiliary component 6 is fixedly connected to the upper surface of the mounting bracket 1. The support rod 5 is in contact with the auxiliary component 6.

[0026] The buffer assembly 3 includes two movable balls 301 that are ball-jointed with the sides of the fixing member 2 and the mounting bracket 1, respectively. The two movable balls 301 are symmetrically arranged. One of the movable balls 301 has a sliding cavity 302 on its circumferential surface, and the other movable ball 301 has a slide rod 303 fixedly connected to its circumferential surface. The slide rod 303 is slidably connected to the sliding cavity 302. Through the buffer structure design of the movable ball 301, the sliding cavity 302 and the slide rod 303, when the fixing member 2 is subjected to the force of the cable, the movable ball 301 can rotate flexibly at the ball joint, while the slide rod 303 slides in the sliding cavity 302 and squeezes the air inside the sliding cavity 302, thereby buffering the force and providing a multi-directional buffer space for the fixing member 2, which can effectively absorb and disperse the impact force from different directions. The buffer assembly 3 also includes a first spring 304 that is fixedly connected between the mounting bracket 1 and the mounting part 2. Both movable balls 301 are located inside the first spring 304. The setting of the first spring 304 further enhances the overall buffering performance of the buffer assembly 3. When the fixing part 2 is subjected to the force of the cable, the first spring 304 will undergo elastic deformation to absorb and store energy. The first spring 304 has a conical structure. When the conical spring is subjected to pressure, its spring coils of different diameters can deform in sequence. As the pressure increases, the spring coils with larger diameters gradually participate in the deformation, further absorbing and dispersing the impact force.

[0027] The auxiliary component 6 includes a fixed frame 601 fixedly connected to the upper surface of the mounting bracket 1. A swing plate 602 is slidably connected inside the fixed frame 601. The bottom end of the support rod 5 contacts the side of the swing plate 602. A connecting rod 603 is hinged to the side of the swing plate 602. The connecting rod 603 is slidably inserted into the central area of ​​the fixed frame 601. A second spring 604, sleeved with the connecting rod 603, is fixedly connected between the connecting rod 603 and the fixed frame 601. The combined design of the fixed frame 601, swing plate 602, connecting rod 603, and second spring 604 provides effective cushioning for the support rod 5. When the support rod 5 is subjected to force from a cable or external factors, the support rod 5 contacts the swing plate 602 and pushes the swing plate 602 to slide within the fixed frame 601. Simultaneously, the connecting rod 603 slides in the central area of ​​the fixed frame 601 and compresses the second spring 604. The second spring 604... The elastic deformation can absorb and dissipate the force; the auxiliary component 6 also includes two elastic metal plates 605 fixedly connected to the side of the swing plate 602. The two elastic metal plates 605 are both arc-shaped and symmetrically arranged. The other end of the two elastic metal plates 605 is fixedly connected to the inner wall of the fixed frame 601. The arrangement of the two elastic metal plates 605 further enhances the buffering and stability performance of the auxiliary component 6. The elastic metal plates 605 are arc-shaped and symmetrically arranged. When the swing plate 602 is subjected to a force and swings, the elastic metal plates 605 will undergo elastic deformation, absorb some energy, and reduce the swing amplitude of the swing plate 602. There are gaps between the swing plate 602 and the inner wall of the fixed frame 601 on both sides along its length direction. The setting of the gaps allows the swing plate 602 to swing more freely when subjected to a force, without being restricted by the inner wall of the fixed frame 601.

[0028] The working principle of the above embodiment is as follows: When fixing the cable, the cable is placed between the two fixing parts 2 and in contact with the rubber plate 4. Then, the two fixing parts 2 are fixed with bolts. After the two fixing parts 2 are installed, the two fixing parts 2 will produce elastic deformation. At this time, the rubber plate 4 tightly fits the cable with its own elasticity and works in synergy with the elastic deformation of the fixing parts 2 to achieve a stable and flexible clamping of the fixing parts 2. This ensures the clamping force to prevent the cable from loosening and avoids damage to the cable due to excessive squeezing.

[0029] When an external force is applied to the cable, the cable will swing. Since the rubber plate 4 extends into the fixing member 2, the bending point of the cable during the swing will always be in contact with the rubber plate 4, thereby reducing the friction on the cable. At the same time, the slide rod 303 can slide in the sliding cavity 302 and squeeze the air inside to buffer the swing force of the cable. The support rod 5 will contact the swing plate 602 and apply force to the swing plate 602, pushing the swing plate 602 to slide in the fixing frame 601. Through the deformation force of the second spring 604 and the elastic metal sheet 605, the swing force of the cable can be buffered to prevent the cable from swinging violently, thereby improving the stability of the cable in complex stress environments.
