Description

Technical Field

[0001] This utility model relates to the field of power engineering, and in particular to an easily detachable power insulator installation structure. Background Technology

[0002] Electrical insulators are crucial devices in power systems, used to support conductors and isolate live parts from grounded components. They are widely used in transmission lines, substations, and other similar locations. Their primary function is to withstand mechanical loads and prevent current leakage, ensuring the safe and stable operation of the power system. Insulators are typically made of ceramic, glass, or composite materials, possessing excellent insulation properties and mechanical strength.

[0003] Existing insulator installation structures typically use bottom bolts for fixing, connecting the insulator to the base with multiple bolts. This installation method not only requires aligning the bolt holes one by one, but also requires using tools to tighten them sequentially, making the process cumbersome and time-consuming. Utility Model Content

[0004] In view of this, the present invention provides an easily detachable power insulator installation structure. The main technical problem to be solved is that the existing insulator installation structure usually adopts the bottom bolt fixing method, which connects the insulator to the base by multiple bolts. This installation method not only requires aligning the bolt holes one by one, but also requires the use of tools to tighten them one by one. The operation process is cumbersome and time-consuming.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an easily detachable power insulator installation structure, including a base, a positioning block fixedly connected to the bottom of the base, and multiple positioning blocks; a main body provided on the top of the base; a connecting column fixedly connected to the bottom of the main body; the connecting column penetrating the base; an adjustment cavity provided inside the connecting column; a screw movably connected to the top of the inner wall of the adjustment cavity; a retaining ring provided at the bottom of the connecting column; the inner diameter of the retaining ring being smaller than the outer diameter of the bottom of the screw; an adjusting plate threadedly connected to the outer wall of the screw; and a rotating groove provided inside the adjusting plate, with multiple rotating grooves. There are multiple rotating slots, and connecting rods are movably connected to the inner walls of the multiple rotating slots. The outer wall of the connecting column has multiple telescopic slots. The top of the inner wall of the adjusting cavity has multiple communicating slots. Each of the multiple communicating slots communicates with multiple telescopic slots. A locking block is provided inside each of the multiple telescopic slots. One end of the locking block is fixedly connected to a spring, and one end of the spring is fixedly connected to the inner wall of the telescopic slot. One end of the locking block is located inside the positioning block. A protrusion is fixedly connected to the bottom of the locking block, and the protrusion penetrates the communicating slot. The bottom of the protrusion is movably connected to the top of the connecting rod.

[0006] By adopting the above technical solution, the inclined surface design allows the locking block and the positioning block to fit tightly together, enhancing the self-locking effect and facilitating the unlocking operation.

[0007] As a further description of the above technical solution: The ends of both the positioning block and the locking block away from the telescopic groove are triangular, and the mating surfaces of the positioning block and the locking block are inclined surfaces.

[0008] By adopting the above technical solution, the bottom of the screw is supported, so that the screw as a whole can be limited. By using the mutual compression of the two inclined surfaces, the main body can be firmly fixed on the base.

[0009] As a further description of the above technical solution: The outer wall of the adjusting plate is fixedly connected to a limiting block, and there are multiple limiting blocks. The inner wall of the adjusting cavity is provided with a limiting groove, and there are multiple limiting grooves. The multiple limiting blocks are respectively located inside the multiple limiting grooves.

[0010] By adopting the above technical solution, the cooperation between the limiting block and the limiting groove ensures the stability of the adjusting plate during movement and prevents deviation or jamming.

[0011] As a further description of the above technical solution: A gasket is provided on the top of the base, the gasket is fitted over the outside of the connecting column, and the gasket is located between the bottom of the base and the main body.

[0012] By adopting the above technical solutions, the gasket effectively buffers vibration and impact, and improves sealing performance.

[0013] As a further description of the above technical solution: The base has multiple positioning holes inside, and the bottom of the main body has multiple positioning posts, each of which is located inside a number of positioning holes.

[0014] By adopting the above technical solution, the positioning column and positioning hole work together to ensure accurate installation and avoid the main body from shifting or loosening.

[0015] As a further description of the above technical solution: A top plate is fixedly connected to the top of the main body. A movable groove is opened inside the top plate. A bidirectional lead screw is movably connected to the inner wall of the movable groove. One end of the bidirectional lead screw passes through the top plate and is fixedly connected to a knob. A movable block is threadedly connected to the outer wall of the bidirectional lead screw. There are two movable blocks. A clamping plate is fixedly connected to the top of each of the two movable blocks. A support block is fixedly connected to the top of the top plate. There are two support blocks. The two support blocks are located at the front and rear ends of the movable groove, respectively.

[0016] By adopting the above technical solutions, the bidirectional lead screw and clamping plate design enables rapid clamping and release of the wire, and the support block enhances the clamping stability.

[0017] By employing the above technical solution, the easily detachable power insulator installation structure of this utility model has at least the following beneficial effects: 1. Compared with existing technologies, this easily detachable power insulator installation structure achieves rapid locking and unlocking of the insulator through the cooperation between the base and the positioning block, as well as the linkage design of the adjusting cavity, screw, adjusting plate, and locking block inside the connecting column. The adjusting plate drives the locking block to extend and retract via a connecting rod, and the inclined self-locking structure of the positioning block makes the installation process simple and reliable. Disassembly only requires rotating the screw to release the lock, avoiding the cumbersome operation of traditional bolt connections and significantly improving installation and maintenance efficiency. Furthermore, the cooperation between the limiting block and the limiting groove ensures the smooth movement of the adjusting plate, enhancing the stability and durability of the structure.

[0018] 2. Compared with existing technologies, this easily detachable power insulator installation structure effectively mitigates vibration and impact between the base and the main body through the use of gaskets, improving sealing performance and extending the insulator's service life. The precise fit between the positioning post and the positioning hole further ensures installation accuracy and prevents the main body from shifting or loosening. The clamping mechanism on the top plate, consisting of a bidirectional lead screw, a moving block, and a clamping plate, allows for quick fixing and release of the conductor via knob adjustment. The support block provides stable support for the clamping operation, making the entire installation structure more flexible and reliable, suitable for various working conditions.

[0021] Reference Figure 1-8 The present invention provides an easily detachable power insulator installation structure comprising: a base 1, a positioning block 2 fixedly connected to the bottom of the base 1 (multiple positioning blocks 2), a main body 3 on the top of the base 1, a connecting post 4 fixedly connected to the bottom of the main body 3, the connecting post 4 penetrating the base 1, an adjusting cavity 5 inside the connecting post 4, a screw 6 movably connected to the top of the inner wall of the adjusting cavity 5, a retaining ring at the bottom of the connecting post 4 (the inner diameter of the retaining ring is smaller than the outer diameter of the bottom of the screw 6), an adjusting plate 7 threadedly connected to the outer wall of the screw 6, a rotating groove 8 inside the adjusting plate 7 (multiple rotating grooves 8), a connecting rod 9 movably connected to the inner wall of the multiple rotating grooves 8, a telescopic groove 10 on the outer wall of the connecting post 4 (multiple telescopic grooves 10), and a connecting groove 11 on the top of the inner wall of the adjusting cavity 5 (multiple connecting grooves 11). Multiple connecting grooves 11 are connected to multiple telescopic grooves 10 respectively. Each telescopic groove 10 is provided with a locking block 12. The ends of the positioning block 2 and the locking block 12 away from the telescopic groove 10 are triangular, and the contact surfaces of the positioning block 2 and the locking block 12 are inclined. One end of the locking block 12 is fixedly connected to a spring 13. One end of the spring 13 is fixedly connected to the inner wall of the telescopic groove 10. One end of the locking block 12 is located inside the positioning block 2. The bottom of the locking block 12 is fixedly connected to a protrusion 14. The protrusion 14 passes through the connecting groove 11, and the bottom of the protrusion 14 is movably connected to the top of the connecting rod 9. The outer wall of the adjusting plate 7 is fixedly connected to a limit block 15, and there are multiple limit blocks 15. The inner wall of the adjusting cavity 5 is provided with a limit groove 16. The base 1 has multiple limit grooves 16, and the multiple limit blocks 15 are located inside the multiple limit grooves 16 respectively.

[0022] During installation, the main body 3 is inserted into the base 1 via the connecting post 4. After the connecting post 4 is fully inserted, the screw 6 is rotated to move the adjusting plate 7 upward, which pushes the protrusion 14 through the connecting rod 9, forcing the locking block 12 to move outward of the telescopic groove 10. Its triangular end is inserted into the positioning block 2 and fits against the inclined surface of the positioning block 2, achieving self-locking fixation. During disassembly, the screw 6 is rotated again to move the adjusting plate 7 downward, releasing the pushing force of the connecting rod 9 on the protrusion 14. Under the elastic force of the spring 13, the locking block 12 retracts back into the telescopic groove 10, disengaging from the positioning block 2, thus easily separating the main body 3 from the base 1.

[0023] A gasket 17 is provided on the top of the base 1. The gasket 17 is fitted over the outside of the connecting post 4. The gasket 17 is located between the bottom of the base 1 and the main body 3. The gasket 17 provides cushioning and sealing. The base 1 has multiple positioning holes 18 inside. The bottom of the main body 3 has multiple positioning posts 19. The multiple positioning posts 19 are located inside the multiple positioning holes 18. The positioning posts 19 ensure the precise alignment of the Sog locking block 12 with the multiple positioning blocks 2.

[0024] A top plate 20 is fixedly connected to the top of the main body 3. A movable groove 21 is opened inside the top plate 20. A bidirectional lead screw 22 is movably connected to the inner wall of the movable groove 21. One end of the bidirectional lead screw 22 passes through the top plate 20 and is fixedly connected to a knob 23. A movable block 24 is threadedly connected to the outer wall of the bidirectional lead screw 22. There are two movable blocks 24. A clamping plate 25 is fixedly connected to the top of each movable block 24. A support block 26 is fixedly connected to the top of the top plate 20. There are two support blocks 26. The two support blocks 26 are located at the front and rear ends of the movable groove 21, respectively. The bidirectional lead screw 22 on the top plate 20 is controlled by the knob 23 to drive the movable block 24 so that the clamping plate 25 can clamp or release the wire, realizing the clamping and release of the line. The support block 26 provides stable support for the clamping mechanism.

[0025] Working principle: In the initial state, multiple locking blocks 12 are kept in a retracted state under the elastic force of spring 13, and are completely housed in the telescopic groove 10 of connecting post 4. During installation, the main body 3 is inserted into the base 1 through the connecting post 4. At this time, since multiple positioning posts 19 are respectively located in multiple positioning holes 18, after the connecting post 4 is fully inserted, rotating the screw 6 causes the adjusting plate 7 to move upward, which pushes the protrusion 14 through the connecting rod 9, forcing the locking block 12 to move outward of the telescopic groove 10. Its triangular end is inserted into the interior of the positioning block 2 and fits against the inclined surface of the positioning block 2 to achieve self-locking fixation. During disassembly, rotating the screw 6 again causes the adjusting plate 7 to move upward. As 7 moves downward, the pushing force of the connecting rod 9 on the protrusion 14 is released, and the locking block 12 retracts back into the telescopic groove 10 under the elastic force of the spring 13, disengaging from the positioning block 2. This allows the main body 3 to be easily separated from the base 1. During this process, the cooperation between the limiting block 15 and the limiting groove 16 ensures that the adjusting plate 7 moves smoothly. The gasket 17 provides buffering and sealing, and the positioning post 19 and the positioning hole 18 ensure precise alignment. The bidirectional lead screw 22 on the top plate 20 is controlled by the knob 23, which drives the moving block 24 to enable the clamping plate 25 to clamp or release the wire, thus achieving the clamping and release of the line. The support block 26 provides stable support for the clamping mechanism.
