A cable electric test ring that is easy to install

Abstract

The utility model discloses a cable electric test ring that is easy to install, including an electric test grounding ring body and a clamping seat. The utility model adopts an insert rod and a limit rod. After the wire is clamped, the second spring can be deformed and reset by loosening the pull plate, and then the insert rod can be pushed downward to achieve the locking operation of the adjustment disk, so as to prevent the adjustment disk from rotating when the subsequent wire rotates, and can effectively prevent the clamping plate from being loosened. In addition, after the rotation of the bidirectional screw rod is completed, the limit rod can be inserted through the bidirectional screw rod by the deformation reset of the first spring, which can further perform the locking and limiting operation on the bidirectional screw rod. The installation directions of the insert rod and the limit rod are different, so it is necessary to generate forces in two different directions at the same time to cause the movement of the clamping plate, which can effectively ensure the stability of the fixation and prevent the wire from detaching. The overall advantages are multiple limits, strong stability, and good anti-detachment effect.

Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a cable electric test ring which is easy to install. Background Art

[0002] The lightning protection and electricity detection grounding ring is a very efficient line lightning protection, electricity detection and grounding equipment. It is installed on the overhead wire near the insulator of the distribution network line. When the wire is struck by lightning and the overvoltage exceeds a certain value, a flashover is caused between the hemispherical head of the lightning protection and electricity detection grounding ring and the metal at the root of the insulator, forming an overvoltage release channel to protect the wire from burns. The lightning protection and electricity detection grounding ring also has the functions of grounding protection and electricity detection.

[0003] The publication number in the existing public technology is: CN211017454U. A lightning protection and electrical testing grounding ring includes a grounding ring and a clamping mechanism arranged on the grounding ring. The clamping mechanism includes a clamping body, a pressure block matched with the clamping body, a bolt arranged on the clamping body, and a nut arranged on the bolt. The clamping body is provided with a clamping groove, the head of the bolt extends in the clamping groove and is connected to the pressure block, and a wire clamping cavity is formed between the pressure block and the clamping body. The upper end of the grounding ring is connected to the clamping body, the outside of the grounding ring is wrapped with an insulating sleeve, and the lower end of the grounding ring is provided with a connecting portion exposed outside the insulating sleeve. The utility model has the advantages of simple structure, stable performance, reliable connection, strong versatility and easy installation.

[0004] However, the above patent still has certain disadvantages when in use: the bolt is fixed only by a nut, and the overall fixing and limiting measures are relatively simple. It is easy to transmit the vibration force to the bolt when the subsequent wire vibrates, causing the bolt to vibrate synchronously and then causing the bolt and nut to move upward, thereby causing the pressure block to detach from the wire, affecting the use effect of the structure, and the overall stability and anti-detachment effect are not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] According to an embodiment of the utility model, a cable electrical testing ring which is easy to install is provided.

[0030] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, according to an embodiment of the utility model, a cable electric test ring that is easy to install includes an electric test grounding ring body 1 and a clamping seat 5. The clamping seat 5 is installed at the middle position on the top of the electric test grounding ring body 1. An adjustment groove 16 is opened in the middle position of the inner surface of one side of the clamping seat 5. A bidirectional screw rod 7 is rotatably connected to the middle position of the adjusting groove 16. The top of the bidirectional screw rod 7 passes through one side of the clamping seat 5 and is connected to the adjusting disk 12. The two sides of the top of the adjusting disk 12 are symmetrically slidably connected with the plug rod 11. The top position of the plug rod 11 is installed with a pull plate 13. The plug rod 11 is provided with a pull plate 13. A second spring 14 is provided around the sleeve, and the two ends of the second spring 14 are respectively connected to the bottom position of the pull plate 13 and the top position of the adjusting disk 12; a plurality of positioning holes 15 are provided around the top surface of the clamping seat 5 below the adjusting disk 12, and the insertion rod 11 and the positioning holes 15 are plugged into each other; a limiting rod 9 is slidably connected to the surface of one side of the clamping seat 5; a first spring 10 is provided around the outer periphery of the limiting rod 9, and the first spring 10 is respectively fixed to the surface of the limiting rod 9 and the surface of the clamping seat 5, and one end of the limiting rod 9 passes through one side of the bidirectional screw 7.

[0031] In one embodiment, a movable seat 8 is sleeved on the outer periphery of both ends of the bidirectional screw 7, a clamping plate 6 is welded to one end of the movable seat 8, and the movable seat 8 is slidably connected to the adjustment slot 16, and the clamping plate 6 is provided to clamp and fix the wire.

[0032] In one embodiment, the exterior of the test grounding ring body 1 is wrapped with an insulating sleeve 2 , and the lower end of the test grounding ring body 1 is provided with a connecting portion 3 exposed outside the insulating sleeve 2 .

[0033] In one embodiment, a hemispherical head 4 exposed outside the insulating sleeve 2 is provided on one side of the surface of the electrical testing grounding ring body 1 corresponding to the connecting part 3. The hemispherical head 4 is a high-voltage electrode used for lightning protection discharge, which can generate discharge with the metal at the root of the insulator to protect the wire from being burned.

[0034] In one embodiment, a groove for clamping the wire is provided on the surface of the clamping plate 6 .

[0035] In one embodiment, a plurality of through holes are provided around the surface of the bidirectional screw 7 for the limiting rod 9 to pass through.

[0036] In one embodiment, a passage is provided inside the clamping seat 5 for inserting the limiting rod 9 .

[0037] In one embodiment, the length of the limiting rod 9 is greater than the diameter of the bidirectional screw 7. The length of the limiting rod 9 is set to ensure that it can smoothly penetrate the bidirectional screw 7, thereby ensuring that it can accurately perform a limiting operation on it.

[0038] Working principle: In actual use, personnel can place the wire on the surface of the clamping plate 6 below, and then rotate the adjusting disk 12 on the top. The rotation of the adjusting disk 12 can drive the rotation of the bidirectional screw 7 connected thereto, so that the two sets of clamping plates 6 connected on its surface can move relatively, thereby effectively clamping and fixing the wire in the middle position. After the wire is clamped, the second spring 14 can be deformed and reset by loosening the pull plate 13, and then the insertion rod 11 can be pushed downward. At this time, the insertion rod 11 can be inserted into the positioning hole 15 to realize the locking operation of the adjusting disk 12, so as to prevent the adjusting disk 12 from rotating during the subsequent wire. It rotates when it moves, thereby avoiding the twisting of the two-way screw 7, which can effectively prevent the clamping plate 6 from loosening and ensure the fixing effect of the wire. In addition, after the two-way screw is rotated, the limit rod 9 can be inserted through the two-way screw 7 through the deformation reset of the first spring 10, which can further lock and limit the two-way screw 7. The installation direction of the insertion rod 11 is different from that of the limit rod 9. Therefore, it is necessary to generate forces in multiple directions at the same time to cause the movement of the clamping plate 6, which can effectively ensure the stability of the fixation and prevent the wire from detaching. The device as a whole has the advantages of multiple limits, strong stability and good anti-detachment effect.
