Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to an insulator with detachable and replaceable components. Background Art

[0002] An insulator is a special insulating control device that plays an important role in overhead transmission lines. It is mostly used on utility poles and gradually developed to be hung on high-voltage wire connection towers. Its purpose is to increase the creepage distance. The difference in its creepage distance is mainly manifested in the different sizes of the insulator umbrella skirts. Most of the existing insulator umbrella skirts and the insulator body are integrally arranged, with a fixed size of the umbrella skirt and a fixed creepage distance. If it is necessary to increase the creepage distance of the insulator, the entire insulator needs to be disassembled and completely replaced, and the entire disassembly and assembly process is cumbersome, time-consuming and laborious.

[0003] In addition, there are also umbrella skirts that are detachable from the insulator body. The umbrella skirts and the insulator are connected by clamping or other means. It should be noted that for such insulators, there are relatively exposed gaps between the umbrella skirts and the insulator. When it rains, rainwater is likely to seep into the space between the insulator body and the umbrella skirt from the gaps. After a long period of heavy rain, rainwater will accumulate between them, seriously affecting the use of the insulator and posing a safety hazard.

[0004] Therefore, how to design an insulator with detachable and replaceable components that can solve the above technical problems is a technical problem that needs to be solved. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide an insulator with detachable and replaceable components, which solves the problems that the size of the existing insulator umbrella skirt is fixed, the creepage distance is fixed, the disassembly and assembly are cumbersome when the creepage distance needs to be increased, and the connection gap between the insulator and the umbrella skirt is exposed.

[0022] The following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments:

[0023] See Figures 1-4 As shown, the solution includes an insulator body 1, a plurality of connecting umbrella skirts 2 detachably connected to the insulator body 1, and a plurality of extended arc edge groups 3 arranged circumferentially along the connecting umbrella skirts 2; preferably, the connecting umbrella skirts 2 and the extended arc edge groups 3 are made of silicone rubber material and have a certain elasticity.

[0024] The insulator body 1 is provided with annular connectors 11 arranged at equal intervals along its height direction. Preferably, the annular connectors 11 and the insulator body 1 are integrally formed. A gap 12 matching the shape and size of the top of the connecting umbrella skirt 2 is left between the inner side surface of the annular connector 11 and the insulator body 1. A connecting groove 111 is formed along the circumferential direction at the bottom of the inner side surface of the annular connector 11. A connecting buckle 21 is correspondingly arranged at the position of the outer side surface of the connecting umbrella skirt 2 corresponding to the connecting groove 111. A connecting card slot 22 is formed along the circumferential direction on the inner side surface of the connecting umbrella skirt 2. A connecting buckle 13 matching the connecting ring groove 23 is fixedly arranged on the insulator body 1 at the position corresponding to the connecting ring groove 23. The connecting groove 111 and the connecting buckle 21, and the connecting card slot 22 and the connecting buckle 13 are all connected by interference fit. In order to increase the friction between them and prevent them from falling off, the roughness of the contact surfaces between the connecting groove 111 and the connecting buckle 21, and the connecting card slot 22 and the connecting buckle 13 can be increased to increase the friction force. When the connecting umbrella skirt 2 is connected to the annular connector 11, the top of the connecting umbrella skirt 2 is placed at the position of the gap 12 between the annular connector 11 and the insulator body 1. Since the bottom of the connecting ring body is arranged on the outer side surface of the connecting umbrella skirt 2, covering the gap between the top of the connecting umbrella skirt 2 and the outer peripheral wall of the insulator, when it rains, the rainwater directly drips onto the outer side surface of the connecting umbrella skirt 2 along the annular connector 11, as much as possible avoiding the rainwater dripping and accumulating between the connecting umbrella skirt 2 and the outer peripheral wall of the insulator.

[0025] A connecting ring groove 23 is also formed at the outer bottom edge of the connecting umbrella skirt 2; each of the extended arc edge groups 3 includes a number of connecting arc edges 31 with adjacent edges connected; the innermost connecting arc edge 31 is attached to the outer edge of the connecting umbrella skirt 2 and a connecting ring block 32 matching the connecting ring groove 23 is provided on the inner side surface of the connecting arc edge 31. A connecting ring groove 23 is also formed along the circumferential direction on the outer side surface of the connecting arc edge 31; the outer side of the connecting arc edge 31 and the inner side of its adjacent connecting arc edge 31 are connected by clamping the connecting ring block 32 with the connecting ring groove 23. By increasing the roughness of the direct contact surface between the connecting ring groove 23 and the connecting ring block 32, the friction force is increased to make the connection between the two more stable. By increasing the number of connecting arc edges 31, the length range is increased to achieve an increase or decrease in the creepage distance of the umbrella skirt, enhancing the practicality.

[0026] A notch 24 is formed on the connecting umbrella skirt 2 to facilitate the passage of the connecting umbrella skirt 2 through the insulator body 1. A sliding groove 25 is formed on one side of the connecting umbrella skirt 2 close to the notch 24, and a second sliding groove 26 is formed on the other side close to the notch 24. The sliding groove 25 and the second sliding groove 26 are spliced to form a slideway 27. A connecting slider 28 matching the shape and size of the slideway 27 is slidably arranged on the connecting umbrella skirt 2, facilitating the passage of the connecting umbrella skirt 2 through the insulator body 1 and fixing it to the outer peripheral wall of the insulator body 1, so that the left and right side edges of the notch 24 of the connecting umbrella skirt 2 are connected. In order to prevent rainwater from dripping from the notch 24, an arc-shaped water guide block 281 is integrally provided on the upper end surface of the connecting slider 28.

[0027] Further, the upper end surface of the connecting arc edge 31 is flush with the upper end surface of the connecting umbrella skirt 2.

[0028] The working principle is generally as follows:

[0029] When installing the insulator body 1, first connect the connecting umbrella skirt 2 with the annular connecting body 11, and connect the connecting arc edge 31 with the connecting umbrella skirt 2 as needed.

[0030] The above is only the specific implementation manner of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
