Description

Technical Field

[0001] This utility model relates to the field of grounding wire technology, and in particular to an adjustable angle grounding wire. Background Technology

[0002] Grounding wires are critical protective devices in power systems used to ensure the safety of workers. Their main function is to reliably connect the conductive parts of electrical equipment to the earth during power outages for maintenance, releasing residual charges and preventing electric shock accidents caused by unexpected power surges. They are widely used in high-voltage electrical work scenarios such as substations, transmission lines, and distribution cabinets. A reliable grounding wire clamping device ensures a low-resistance path is formed between the grounding terminal and the conductor, which is the core element for achieving effective grounding.

[0003] Specifically, existing grounding wire devices generally suffer from limited functionality in practical use. Most only have clamping structures with fixed angles or limited opening and closing functions, lacking flexible angle adjustment mechanisms. The grounding wire is not easily rotated for adjustment, and the connection between the clamp and the rod is usually rigid, making it impossible to adjust the clamping angle according to actual space requirements after clamping the conductor. This results in ineffective grounding in complex working conditions or confined spaces, severely limiting its application range. Because it cannot perform grounding work at different angles, operators often need to carry multiple specifications or types of grounding wires to cope with different scenarios, increasing tool management costs and the complexity of on-site operations. Therefore, in response to the many shortcomings of existing technologies, we urgently need an innovative adjustable-angle grounding wire to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable angle grounding wire, which solves the problem that existing grounding wires are not easy to rotate and adjust, and the clamp and rod are usually rigidly connected, making it impossible to adjust the clamping angle according to actual space requirements after clamping the conductor. This results in the inability to achieve effective grounding in complex working conditions or confined spaces, which seriously limits the scope of application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-angle grounding wire includes a protective frame, a bearing frame fixedly connected to the inner side of the protective frame, and a bearing plate rotatably connected to the inner side of the bearing frame. Rotating rods are fixedly connected to both sides of the bearing plate, with one end of one of the two rotating rods rotatably connected to the inner wall of the bearing frame, and one end of the other rotating rod penetrating through the side wall of the bearing frame. A set of clamping plates is slidably connected to both sides of the bearing plate, with two clamping plates in each set, and the two clamping plates in each set are elastically connected to each other. Top plates are fixedly connected to both sides of the top of the protective frame, and protective nets are fixedly connected to the bottom of the two top plates by bolts.

[0006] Preferably, one end of one of the two rotating rods is rotatably connected to the inner wall of the support frame via a rotating shaft, and one end of the other rotating rod passes through the side wall of the support frame via a bearing sleeve.

[0007] Preferably, a limiting plate is fixedly connected to one end of one of the two rotating rods, and a limiting rod is provided on one side of the limiting plate. A limiting groove for use with the limiting rod is provided on both the limiting plate and the side wall of the bearing frame. Several limiting grooves are provided on the limiting plate.

[0008] Preferably, a handle is fixedly connected to one side of the limiting plate, and a base plate is fixedly connected to both sides of the lower part of the bearing frame, with one side of each base plate fixedly connected to the inner wall of the protective frame.

[0009] Preferably, all the clamps are fixedly connected to the top of the slider, and all the sliders are slidably connected to the support plate through the slide groove.

[0010] Preferably, all sliders are fixedly connected to a handle at the top, all clamps are fixedly connected to an anti-slip plate on one side, and the two clamps in each set are elastically connected by a tension spring.

[0011] This utility model has the following beneficial effects: By setting a rotating connection structure between the support plate and the support frame, combined with the rotation drive of the rotating rod, the overall angle of the support plate and its clamping plates is continuously adjustable. This overcomes the shortcomings of traditional grounding wire clamps that are rigidly connected to the rod, making it impossible to adjust the clamping angle according to actual space requirements. This allows for flexible adjustment of the grounding wire connection direction in confined spaces or complex wiring environments, effectively improving the adaptability and operational efficiency of the device. By setting two sets of clamping plates on both sides of the support plate, each set consisting of two clamping plates connected elastically, not only is adaptive clamping of cables of different diameters achieved, improving the reliability and versatility of clamping, but also avoiding additional locking operations, simplifying the work process, and solving the problem of limitations in clamping structure functionality. The availability of grounding wires in various specifications reduces the types of tools and management costs on site. The combined structure of the protective frame and protective net effectively isolates the external environment from interference with the internal rotation and clamping mechanisms, improving the durability and safety of the equipment in outdoor or industrial environments. The top plate and protective net are bolted together, facilitating later maintenance and cleaning and extending the overall service life of the device. The overall structure maintains a compact structure and ease of operation while achieving angle adjustment. Angle setting and cable clamping can be completed without complex auxiliary tools, significantly improving the flexibility and safety of grounding operations. It effectively solves the problem of limited application scope caused by structural rigidity and inconvenient adjustment in existing technologies, and has good practical value and promotion prospects.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Reference Figure 1-5 An adjustable angle grounding wire includes a protective frame 1, a bearing frame 5 fixedly connected to the inner side of the protective frame 1, and a bearing plate 6 rotatably connected to the inner side of the bearing frame 5. Rotating rods 9 are fixedly connected to both sides of the bearing plate 6, and one end of one of the two rotating rods 9 is rotatably connected to the inner wall of the bearing frame 5, while one end of the other rotating rod 9 passes through the side wall of the bearing frame 5. A set of clamping plates 7 are slidably connected to both sides of the bearing plate 6, and each set of clamping plates 7 has two clamping plates, and the two clamping plates 7 in each set are elastically connected to each other. Top plates 3 are fixedly connected to both sides of the top of the protective frame 1, and a protective net 2 is fixedly connected to the bottom of each of the two top plates 3 by bolts.

[0017] First, the adjustable-angle grounding wire is moved to the vicinity of the electrical equipment to be operated on. The internal structure is protected by the protective frame 1 to prevent external foreign objects or mechanical damage from affecting safe use. When it is necessary to adjust the clamping angle of the grounding wire, the operator can manually rotate the rotating rod 9 that passes through the side wall of the support frame 5. Since the rotating rod 9 is rotatably connected to the support frame 5, and the rotating rod 9 on the other side also forms a rotating pair with the inner wall of the support frame 5, the support plate 6 can be driven to rotate as a whole around the axis of the two rotating rods 9 during the rotation. The two sides of the support plate 6 are fixedly connected to the two rotating rods 9 respectively to ensure the stability and synchronization during the rotation. As the support plate 6 rotates, the two sets of clamping plates 7 installed on it also change their spatial orientation, thereby realizing the overall angle adjustment of the grounding clamping direction. After adjusting to the required angle, stop rotating the rotating rod 9. At this time, the support plate 6 is held in the set position. Then, place the conductor cable or metal part to be grounded into two of the clamping plates 7. Between the clamping plates 7, since the two clamping plates 7 in each set of clamping plates 7 are elastically connected, that is, there are springs or other elastic elements inside, when the cable is inserted, the two clamping plates 7 are opened by force. After the cable is in place, the elastic elements return to their deformation, so that the two clamping plates 7 form a clamping force on the cable, achieving reliable clamping. This clamping method can automatically adapt to cables of different diameters without the need for an additional locking mechanism. After clamping is completed, the other end of the grounding wire is connected to the grounding stake or earth connection point to form a complete grounding circuit. Throughout the process, the two top plates 3 at the top of the protective frame 1 are fixedly connected to the protective net 2 by bolts. The protective net 2 covers the top of the bearing frame 5 to prevent foreign objects from falling into the bearing plate 6 area during operation and affecting the normal operation of the rotating rod 9 or the clamping plates 7. At the same time, the bolt connection method facilitates disassembly and maintenance. When it is necessary to clean or replace internal parts, the bolts can be loosened and the protective net 2 can be removed for operation. The entire device coordinates the operation between adjusting the angle, clamping the cable, and the protective structure, meeting the flexible use needs under complex working conditions.

[0018] Furthermore, one end of one of the two rotating rods 9 is rotatably connected to the inner wall of the support frame 5 via a rotating shaft, and one end of the other rotating rod 9 passes through the side wall of the support frame 5 via a bearing sleeve. The rotating rods 9 on both sides of the support plate 6 are rotatably connected to the support frame 5 via rotating shafts and bearing sleeves, respectively. During the operation, when the operator rotates the rotating rod 9 that passes through the side wall, the bearing sleeve provides stable support and a low-friction rotation environment to ensure smooth rotation. At the same time, the rotating shaft at the other end keeps the other side of the support plate 6 rotating stably. The two work together to make the support plate 6 rotate smoothly around the axis of the two rotating rods 9, thereby improving the stability and smoothness of the rotation process of the support plate 6 and reducing the difficulty of adjustment or angle deviation caused by loose connection or excessive friction.

[0019] Furthermore, a limiting plate 14 is fixedly connected to one end of one of the two rotating rods 9, and a limiting rod 15 is provided on one side of the limiting plate 14. A limiting groove 17 for use with the limiting rod 15 is provided on both the limiting plate 14 and the side wall of the bearing frame 5. Several limiting grooves 17 are provided on the limiting plate 14. When the bearing plate 6 rotates to the required angle, the limiting rod 15 is inserted into the limiting groove 17 aligned with the side wall of the bearing frame 5. In the working process, after the angle adjustment is completed, the limiting rod 15 is inserted into the corresponding limiting groove 17 to fix the position of the limiting plate 14, thereby locking the rotational degree of freedom of the rotating rod 9. This achieves the effect of accurately fixing the rotation angle of the bearing plate 6 after the adjustment is completed, preventing angle deviation due to vibration or external force, and improving the stability of the clamping structure during the grounding operation.

[0020] Furthermore, a handle 16 is fixedly connected to one side of the limiting plate 14, and base plates 4 are fixedly connected to both sides of the lower part of the bearing frame 5. One side of each base plate 4 is fixedly connected to the inner wall of the protective frame 1. The operator can easily rotate the limiting plate 14 by holding the handle 16, thereby driving the rotating rod 9 and the bearing plate 6 to adjust the angle. At the same time, the base plate 4 firmly connects the bearing frame 5 to the inside of the protective frame 1. In the working process, the handle 16 serves as a force application point to facilitate manual angle adjustment, while the base plate 4 ensures that the bearing frame 5 does not shift or deform when subjected to force. This achieves the effect of improving the convenience of operation while enhancing the overall structural support strength, ensuring that the angle adjustment mechanism maintains structural stability during repeated use.

[0021] Furthermore, all clamping plates 7 are fixedly connected to the top of a slider 11, and all sliders 11 are slidably connected to the support plate 6 through a slide groove 12. The clamping plate 7 moves linearly along the surface of the support plate 6 by sliding the slider 11 in the slide groove 12. During the operation, when the clamping plate 7 is subjected to the force of cable insertion or elastic element, the slider 11 slides synchronously in the slide groove 12 to ensure that the movement direction of the clamping plate 7 is stable and will not deflect or jam. This achieves the effect of constraining the movement trajectory of the clamping plate 7, improving the guidance and reliability of the clamping action, and preventing poor contact or clamping failure due to misalignment during the clamping process.

[0022] Furthermore, a handle 10 is fixedly connected to the top of all sliders 11, and an anti-slip plate 8 is fixedly connected to one side of all clamping plates 7. The two clamping plates in each group are elastically connected by a tension spring 13. The operator can pull the handle 10 to separate the clamping plates 7 along the slide groove 12, thereby opening the clamping opening to insert the cable. The anti-slip plate 8 increases the friction between the clamping plates 7 and the cable, and the tension spring 13 provides the reset pull force. In the working process, the clamping plates 7 are first pulled open by the handle 10, the cable is inserted and then released. The tension spring 13 drives the clamping plates 7 to return to their original position and clamp the cable. The anti-slip plate 8 effectively prevents the cable from slipping off, achieving the effects of facilitating manual operation of clamping and releasing, enhancing clamping stability, preventing the cable from loosening and falling off, and improving clamping adaptability and safety.

[0023] In summary: First, the adjustable-angle grounding wire is transported as a whole to the work site where the power equipment is shut down for maintenance. The protective frame 1 provides basic protection for the internal load-bearing structure, preventing damage from external impacts or foreign objects during transportation and placement. The top plates 3, fixedly connected to both sides of the top of the protective frame 1, are bolted to the protective netting 2. This protective netting 2 covers the load-bearing frame 5, effectively preventing tools, dust, or rainwater falling from above from entering the interior and affecting the mechanism's operation. When grounding is required, the operator holds the lever 16 fixed to one side of the limit plate 14 and rotates the rotating rod 9 that passes through the side wall of the load-bearing frame 5. The bearing sleeve achieves a rotatable connection with the side wall of the support frame 5, providing low-friction and high-stability rotational support. Simultaneously, the rotating rod 9 on the other side of the support plate 6 is rotatably connected to the inner wall of the support frame 5 via a rotating shaft, forming a stable double-pivot rotational structure. As the handle 16 rotates, it drives the entire support plate 6 to rotate synchronously around the axes of the two rotating rods 9, achieving spatial angle adjustment of the support plate 6 and its mounted components. During adjustment, a set of clamping plates 7 is provided on each side of the support plate 6, each set including two clamping plates 7. A slider 11 is fixedly connected to the top of each clamping plate 7. The slider 11 is embedded in a groove 12 opened on the support plate 6 and can slide along it. The movement ensures that the clamping plate 7 maintains linear motion during opening and closing, preventing offset or jamming. After the bearing plate 6 rotates to the required angle, the limiting rod 15 is inserted into the alignment position of a limiting groove 17 on the limiting plate 14 with the corresponding limiting groove 17 on the side wall of the bearing frame 5, achieving angle positioning and locking to prevent angle offset due to vibration during subsequent clamping or operation. After the angle is fixed, the operator pulls the handle 10 fixed at the top of the slider 11 to slide the two clamping plates 7 outward along the slide groove 12, overcoming the tension of the tension spring 13, opening the clamping jaws, inserting the conductor cable or metal conductor to be grounded between the two clamping plates 7, and releasing the handle 10. Afterwards, the tension spring 13 returns to its original deformation, pulling the two clamping plates 7 inward to close, applying clamping force to the cable. At the same time, the anti-slip plate 8 fixed on one side of the clamping plate 7 contacts the cable surface, increasing friction and preventing slippage. After clamping is completed, the other end of the grounding wire is connected to the grounding stake or grounding busbar to form a reliable grounding path. The entire bearing structure is supported by the bottom plates 4 on both sides of the lower part of the bearing frame 5 and the inner wall of the protective frame 1, ensuring that the bearing frame 5 does not deform or shift when subjected to force. All components operate stably under the coordinated structure of the protective frame 1, the protective net 2, the bearing frame 5, and the bearing plate 6, meeting the flexible grounding requirements under different spatial conditions.The combination of the protective frame 1, top plate 3, protective net 2, and bolts provides comprehensive protection for the internal rotation and clamping mechanism, effectively isolating external environmental interference and improving the durability and safety of the equipment in outdoor or complex industrial environments. The bolted connection also facilitates disassembly and maintenance. The rotating rods 9 on both sides of the bearing plate 6 are connected to the bearing frame 5 via shafts and bearing sleeves, ensuring the smoothness and low friction of the bearing plate 6's rotation, improving the smoothness of adjustment operations and long-term reliability. The combination of the limiting plate 14, limiting rod 15, and limiting groove 17 enables precise locking of the bearing plate 6 at multiple preset angle positions, solving the problem of traditional grounding wires being unable to fix the adjustment angle and prone to displacement due to external forces, significantly enhancing the stability of the clamping structure during operation. The connection between the handle 16 and the limiting plate 14 provides a convenient force application point for angle adjustment, improving the ergonomics of operation. Combined with the reinforcing connection of the base plate 4 to the bearing frame 5, the overall structural rigidity is enhanced. The anti-deformation capability ensures the structural integrity of the adjustment mechanism during repeated use. The sliding cooperation between the slider 11 and the slide groove 12 constrains the movement trajectory of the clamping plate 7, ensuring that its opening and closing action is carried out in a straight line, avoiding poor contact or uneven clamping force due to misalignment during clamping, thus improving the reliability and consistency of clamping. Through the coordinated setting of the handle 10, anti-slip plate 8 and tension spring 13, the clamping plate 7 achieves manual quick opening and closing, automatic clamping and anti-slip functions, which is easy to operate and adapts to the clamping needs of cables of different diameters. No additional locking tools are required, which improves work efficiency and safety. The overall structure has formed a systematic improvement in terms of multi-angle adjustment, stable clamping, convenient operation and reliable protection, effectively overcoming the technical defects of existing grounding wires such as single function, inconvenient adjustment, weak clamping and poor adaptability. It has the characteristics of reasonable structure, flexible use and safety and reliability, and is suitable for various high-voltage operation scenarios such as substations, transmission lines, and distribution cabinets. It has good practical value and application prospects.
