Description

Technical Field

[0001] The utility model relates to a polycrystalline silicon insulator, belonging to the technical field of power transmission. Background Art

[0002] An insulator is a special insulating control component, and its main function is to provide mechanical fixation and electrical insulation for electrical equipment and conductors in power transmission and supply lines. It can support the conductors of transmission lines and power equipment, prevent discharge between the wire and the bracket, and thus ensure the insulation state of power equipment. As disclosed in the Chinese utility model patent with the authorization announcement number CN214588247U, the existing insulator includes an insulator body. A plurality of umbrella skirt sleeves are arranged on the insulator body along its length direction. One end of the insulator body is provided with a mounting member for detachably mounting the insulator body on a fixed object in the use state. The other end of the insulator body is provided with a fixing member. A fixing hole for the cable to pass through is formed between the fixing member and the end of the insulator body for fixing the cable in the use state. The mounting member, the insulator body, and the fixing member are all made of polycrystalline silicon material and integrally formed. For this kind of insulator, the fixing member at the top and the insulator body are of an integral structure. When fixing the cable, one end of the cable needs to be inserted into the fixing hole on the insulator. When the length of the cable is relatively long, it is rather inconvenient to fix the cable with this kind of structure. Summary of the Invention

[0003] The purpose of the utility model is to provide a polycrystalline silicon insulator to solve the technical defect that it is inconvenient to fix the cable at the top of the polycrystalline silicon insulator in the prior art.

[0004] To solve the above problems, the technical solution adopted by the present utility model is as follows: A polycrystalline silicon insulator includes an insulator body. A plurality of umbrella skirt sleeves are arranged on the insulator body at intervals from top to bottom. An installation part is provided at the bottom end of the insulator body for fixing the insulator body on the cross arm of a utility pole or a tower in the use state. A cable fixing part is provided at the top end of the insulator body for fixing a cable line in the use state. The cable fixing part includes a limiting part and a locking part. A lower groove penetrating both sides of the insulator body is provided at the top end of the insulator body. One end of the limiting part is rotatably connected to one side of the top of the insulator body located in the lower groove. The locking part is arranged on the other side of the lower groove at the top of the insulator body. When the limiting part is flipped to one side of the lower groove, it is used to place the cable line in the lower groove. When the limiting part is flipped above the lower groove, it is used to fix the cable line in the lower groove. The locking part is used to lock the end of the limiting part to prevent the limiting part from rotating in the use state. The present utility model provides a cable fixing part at the top end of the polycrystalline silicon insulator. By flipping the limiting part, the cable line is placed in the lower groove, and then the limiting part is flipped again, and the limiting part is fixed by the locking part, thus completing the fixation of the cable line and the polycrystalline silicon insulator. Compared with the prior art, the present utility model is more convenient for fixing the cable line.

[0005] As a further improvement of the present utility model, two first connecting ear plates protrude upward on one side of the top of the insulator body located in the lower groove, and a first connecting hole is provided in each of the two first connecting ear plates. A connecting protrusion protrudes from each of the two sides of one end of the limiting part, and the two connecting protrusions are respectively arranged in the two first connecting holes and can rotate in the first connecting holes for the flipping of the limiting part relative to the insulator body. The present utility model enables the limiting part to flip relative to the polycrystalline silicon insulator by providing the first connecting ear plates and matching the connecting protrusions on the limiting part with the first connecting holes on the first connecting ear plates.

[0006] As a further improvement of the present utility model, the locking part includes a locking screw and a locking nut. One end of the locking screw is provided with a rotating shaft perpendicular to it. Two second connecting ear plates are provided on one side of the top of the insulator body located in the lower groove, and a second connecting hole is provided in each of the two second connecting ear plates. The two ends of the rotating shaft are respectively arranged in the two second connecting holes. A through hole penetrating the upper and lower parts is provided at the end of the limiting part. The locking screw passes through the through hole and is in threaded cooperation with the locking nut. The locking nut presses the limiting part for the fixation of the limiting part. The present utility model can fix the limiting part or disengage the limiting part from the locking screw through the threaded cooperation of the locking screw and the locking nut, which is more convenient for fixing the cable line.

[0007] As a further improvement of the present utility model, it further includes a spring sleeved on the locking screw. In the use state, the top end of the spring abuts against the limiting member, and the bottom end abuts against the rotating shaft. The spring is provided in the present utility model. In the use state, the spring abuts against the limiting member, which can effectively prevent the locking nut from loosening.

[0008] As a further improvement of the present utility model, an upper groove is formed on the limiting member. In the state where the limiting member presses the cable, the top of the cable is located in the upper groove. The upper groove is provided on the limiting member in the present utility model to increase the contact area between the limiting member and the cable, thereby playing a role in protecting the cable.

[0009] In summary, the beneficial effects of the present utility model are as follows: Compared with the prior art, the present utility model facilitates fixing the cable to the end of the insulator body through the flipping of the limiting member and the cooperation between the locking member and the limiting member.

[0014] The following further describes the specific embodiments of the present utility model with reference to the drawings.

[0015] Such as Figures 1 to 3The shown polycrystalline silicon insulator includes an insulator body 1. A plurality of umbrella skirt sleeves 2 are arranged at equal intervals from top to bottom on the insulator body 1. The diameters of the plurality of umbrella skirt sleeves 2 are equal, and the edges of the umbrella skirt sleeves 2 incline downward. In the present utility model, the umbrella skirt sleeve 2 and the insulator body 1 are integrally formed. At the bottom end of the insulator body 1, there is an installation part 3 for fixing the insulator body 1 on the cross arm of a utility pole or a tower in the use state. The installation part 3 in the present utility model is cylindrical and integrally formed with the insulator body 1. The installation part 3 coincides with the central axis of the insulator body 1, and the diameter of the installation part 3 is smaller than that of the insulator body 1. External threads are provided on the installation part 3. During use, the installation part 3 is inserted into the installation hole on the cross arm, and a nut is arranged on the installation part 3, thereby fixing the insulator body 1 on the cross arm. At the top end of the insulator body 1, there is a cable fixing part 4 for fixing a cable line in the use state. The cable fixing part 4 in the present utility model includes a limiting part 5 and a locking part 6. At the top end of the insulator body 1, there is a lower groove 7 penetrating both sides of the insulator body 1, that is, the lower groove 7 is a horizontal groove. The limiting part 5 is a long strip with a rectangular longitudinal section. One end of the limiting part 5 is rotatably connected to one side of the top of the insulator body 1 where the lower groove 7 is located. The locking part 6 is arranged on the other side of the top of the insulator body 1 where the lower groove 7 is located. When the limiting part 5 is flipped to one side of the lower groove 7, the top of the lower groove 7 is unobstructed, and the cable line can be placed downward into the lower groove 7 from above the lower groove 7. When the limiting part 5 is flipped above the lower groove 7, the limiting part 5 prevents the cable line from sliding out of the lower groove 7 from above the lower groove 7, and the cable line can be fixed in the lower groove 7. The locking part 6 in the present utility model is used to lock the end of the limiting part 5 to prevent the limiting part 5 from rotating in the use state.

[0016] As Figures 1 to 3 shown, in order to facilitate the rotational connection between the limiting part 5 and the insulator body 1, in the present utility model, two first connection ear plates 8 protrude upward on one side of the top of the insulator body 1 where the lower groove 7 is located. The two first connection ear plates 8 are parallel, and a first connection hole 9 is formed in each of the two first connection ear plates 8. The central axes of the first connection holes 9 on the two first connection ear plates 8 are collinear. On both sides of one end of the limiting part 5, a connection protrusion 10 protrudes respectively. The longitudinal section of the connection protrusion 10 is circular, and the diameters of the two connection protrusions 10 are slightly smaller than the aperture of the first connection hole 9. The two connection protrusions 10 are respectively arranged in the two first connection holes 9 and can rotate in the first connection holes 9. The rotation of the connection protrusion 10 in the first connection hole 9 is used for the flipping of the limiting part 5 relative to the insulator body 1.

[0017] As Figures 1 to 3As shown in the figure, the locking member 6 in the present utility model includes a locking screw 11 and a locking nut 12. One end of the locking screw 11 is provided with a rotating shaft 13 perpendicular thereto. The locking screw 11 and the rotating shaft 13 are integrally formed and made of metal. On the top of the insulator body 1, two second connecting ear plates 14 are provided on one side of the lower groove 7. The two second connecting ear plates 14 are parallel. Each of the two second connecting ear plates 14 is provided with a second connecting hole 15. The center lines of the second connecting holes 15 on the two second connecting ear plates 14 are collinear. The two ends of the rotating shaft 13 are respectively arranged in the two second connecting holes 15 and can rotate in the second connecting holes 15. In the present utility model, a through hole 16 penetrating up and down is provided at one end of the limiting member 5 away from the connecting protrusion 10. The through hole 16 is an oblong through hole (i.e., a waist-shaped hole) to facilitate the top end of the locking screw 11 to extend into the through hole 16. The locking screw 11 passes through the through hole 16 and is in threaded cooperation with the locking nut 12. The locking nut 12 presses the limiting member 5 for fixing the limiting member 5.

[0018] As Figures 1 to 3 shown in the figure, the present utility model is provided with a spring 17. The spring 17 is sleeved on the locking screw 11. In the use state of tightening the locking nut 12, the top end of the spring 17 abuts against the limiting member 5, and the bottom end of the spring 17 abuts against the rotating shaft 13. In the present utility model, an upper groove 18 is provided on the limiting member 5. In the state where the limiting member 5 presses the cable, the top of the cable is located in the upper groove 18.

[0019] When fixing the cable in the present utility model, first unscrew the locking nut 12, turn over the limiting member 5, place the cable in the lower groove 7, then turn over the limiting member 5, and at the same time rotate the locking screw 11 to make the top end of the locking screw 11 extend into the through hole 16 on the limiting member 5, and then install the locking nut 12 on the locking screw 11 and press the limiting member 5.

[0020] Parts not specifically described in the above description are all prior art or can be realized through prior art. Moreover, the specific implementation cases described in the present utility model are only the preferred implementation cases of the present invention and are not used to limit the implementation scope of the present utility model. That is, equivalent changes and modifications made according to the content of the patent scope of the present utility model should all be regarded as the technical scope of the present utility model.
