[0059] Embodiment one

[0060] As shown in Figures 1 to 4 The present embodiment provides a wire insulation protection device, which can prevent electric shock during maintenance and repair, ensure job safety, improve job efficiency and reduce maintenance and repair cost. The wire insulation protection device comprises a mounting base body 1, an elastic clamping piece 2, a pressing structure 3 and an insulation cover 4.

[0061] Among them, refer to Figure 1 and Figure 2, the elastic clamping piece 2 is provided on the mounting base 1, the elastic clamping piece 2 is provided with a clamping groove 23 for clamping the electric wire 100 to be insulated. The compression structure 3 is movably arranged on the mounting base 1, the compression structure 3 comprises a first compression part 31 and a second compression part 32 arranged on both sides of the elastic clamping piece 2, when the compression structure 3 moves towards the elastic clamping piece 2, the first compression part 31 and the second compression part 32 can extrude the electric wire 100 clamped in the clamping groove 23 of the elastic clamping piece 2. The insulation cover 4 is movably connected to the mounting base 1 and has a first position and a second position, in the first position, the insulation cover 4 avoids the electrically conductive connector 101 of the electric wire 100 (as shown in Figure 1 ), and in the second position, the insulation cover 4 covers the electrically conductive connector 101 of the electric wire 100 (as shown in Figure 2 ).

[0062] The electric wire insulation protection device provided by the embodiment can ensure that the insulation cover 4 is in the first position before the electric wire 100 to be insulated is removed from the equipment to be maintained (for example, an electric meter), so that the subsequent removal of the electric wire 100 is not hindered, and the first compression part 31 and the second compression part 32 of the compression structure 3 do not compress the elastic clamping piece 2, thereby facilitating the subsequent fixing of the electric wire 100. Then, the part of the electric wire 100 with the insulation layer is clamped into the clamping groove 23 of the elastic clamping piece 2, the compression structure 3 is driven to move towards the elastic clamping piece 2, and the first compression part 31 and the second compression part 32 extrude the elastic clamping piece 2 to clamp the electric wire 100, so as to fix the position of the electric wire 100.

[0063] Then, the connection between the electric wire 100 and the equipment to be maintained is removed, the electrically conductive connector 101 of the electric wire 100 is exposed, and the insulation cover 4 is operated to switch from the first position to the second position, so that the electrically conductive connector 101 of the electric wire 100 is covered by the insulation cover 4, thereby isolating the electrically conductive connector 101 of the electric wire 100 from the outside, achieving the insulation protection of the electric wire 100, and preventing electric shock when the maintenance personnel maintain the equipment to be maintained, thereby ensuring the safety of the maintenance personnel. At the same time, the existence of the insulation cover 4 can also prevent the electric wire 100 from being in contact with the electric wire 100 and causing a short circuit, thereby ensuring the stable operation of the power system.

[0064] After the maintenance is completed, the insulation cover 4 is adjusted from the second position to the first position, and the wiring operation is performed. After the wiring is completed, the compression structure 3 is reversely moved to release the elastic clamping piece 2 by the first compression part 31 and the second compression part 32, and finally the electric wire 100 is removed from the clamping groove 23 of the elastic clamping piece 2. When the electric wire insulation protection device is used to insulate the electric wire 100, only clamping and covering operations are needed, without the need for other auxiliary tools, the operation is simple, the maintenance efficiency can be improved, and the maintenance cost can be reduced.

[0065] Optionally, the mounting base 1, the elastic holder 2, the pressing structure 3 and the insulating cover 4 are all made of insulating material. In this way, the insulation performance of the whole device can be improved, the electric shock can be effectively prevented, and the use safety can be improved. For example, the insulating material is plastic with certain elasticity, which can not only ensure the insulation effect, but also make the overall structure solid, durable, easy to produce and maintain.

[0066] Optionally, referring to Figure 1 , Figure 2 and Figure 3 , the elastic holder 2 includes a first clamping part 21 and a second clamping part 22 arranged at intervals, and a clamping groove 23 is formed between the first clamping part 21 and the second clamping part 22. When the pressing structure 3 moves relative to the mounting base 1, the first clamping part 21 and the second clamping part 22 move closer to or away from each other. When the pressing structure 3 is driven to move close to the elastic holder 2, the first pressing part 31 and the second pressing part 32 jointly press the elastic holder 2, so that the first clamping part 21 and the second clamping part 22 move close to each other, thereby clamping the electric wire 100. When the pressing structure 3 is driven to move away from the elastic holder 2, the force of the first pressing part 31 and the second pressing part 32 on the elastic holder 2 decreases, and the first clamping part 21 and the second clamping part 22 can move away from each other, thereby releasing the electric wire 100, and facilitating the operation of the electric wire 100 to move away from the elastic holder 2. By moving the pressing structure 3 forward or backward, the first clamping part 21 and the second clamping part 22 can clamp or release the electric wire 100, which can reduce the operation difficulty, facilitate the on-site operation of the maintenance personnel, and improve the operation efficiency.

[0067] In this embodiment, the first clamping part 21 and the second clamping part 22 are both made of flexible material and can be elastically deformed. When the pressing structure 3 moves close to the elastic holder 2, the first clamping part 21 and the second clamping part 22 move close to each other and are elastically deformed, thereby accumulating elastic potential energy. When the pressing structure 3 moves away from the elastic holder 2, the first clamping part 21 and the second clamping part 22 move away from each other under the action of their own elastic force, thereby automatically releasing the electric wire 100 without additional operation, and further simplifying the operation steps of the electric wire 100 insulation protection.

[0068] Further, the first clamping part 21 and the second clamping part 22 are integrally formed members, and the overall cross-sectional shape is C-shaped, which can simplify the structure design and reduce the processing cost. For example, the elastic holder 2 is made of rubber material, or the elastic holder 2 is made of plastic that can be elastically deformed.

[0069] In other embodiments, the first clamping part 21 and the second clamping part 22 can also be separately processed and formed, one end of each of which is rotationally connected to the mounting base 1 and a torsion spring is installed, and when the pressing structure 3 moves away from the first clamping part 21 and the second clamping part 22, the first clamping part 21 and the second clamping part 22 move away from each other under the elastic force of the torsion spring, thereby releasing the electric wire 100.

[0070] Optionally, referring to Figure 2 、 Figure 3 and Figure 4 , the side of the first clamping part 21 and the second clamping part 22 away from each other is provided with a pushing inclined surface 24, which is inclined away from the clamping groove 23, and when the pressing structure 3 moves relative to the mounting base 1, the first pressing part 31 and the pushing inclined surface 24 of the first clamping part 21 are in sliding cooperation, and the second pressing part 32 and the pushing inclined surface 24 of the second clamping part 22 are in sliding cooperation. Due to the inclination of the pushing inclined surface 24 away from the clamping groove 23, when the pressing structure 3 moves close to the elastic clamping part 2, the first pressing part 31 generates an inward pushing force on the first clamping part 21, and the second pressing part 32 generates an inward pushing force on the second clamping part 22, so that the first clamping part 21 and the second clamping part 22 move close to each other, thereby clamping the electric wire 100.

[0071] In addition, the setting of the pushing inclined surface 24 can adjust the distance of the movement of the pressing structure 3 according to the size of the wire diameter of the electric wire 100, so as to change the distance of the first clamping part 21 and the second clamping part 22 moving close to each other, thereby changing the clamping force of the first clamping part 21 and the second clamping part 22, which can adapt to clamp electric wires 100 of different wire diameters, expand the use range of the electric wire insulation protection device, and have stronger universality.

[0072] Optionally, referring to Figure 2 and Figure 3 , the side of the first pressing part 31 facing the second pressing part 32 has a first pressing surface 311, and the side of the second pressing part 32 facing the first pressing part 31 has a second pressing surface 321, and the first pressing surface 311 and the second pressing surface 321 can contact the elastic clamping part 2. When the pressing structure 3 is driven to move relative to the mounting base 1, the first pressing surface 311 and the second pressing surface 321 jointly press the elastic clamping part 2, so as to clamp the electric wire 100 in the clamping groove 23.

[0073] Referring to Figure 3, the first pressing surface 311 and the second pressing surface 321 each comprise a first inclined surface 3111, a pressing flat surface 3112 and a second inclined surface 3113 connected in sequence, the two first inclined surfaces 3111 are inclined towards each other in a direction away from the pressing flat surface 3112, and the two second inclined surfaces 3113 are inclined towards each other in a direction away from the pressing flat surface 3112. The two first inclined surfaces 3111 can be in contact with the abutting inclined surface 24 of the first clamping part 21 and the abutting inclined surface 24 of the second clamping part 22 respectively, and by adjusting the moving distance of the pressing structure 3, the position of the first inclined surface 3111 in contact with the abutting inclined surface 24 can be changed, so as to change the clamping force of the first clamping part 21 and the second clamping part 22, and adapt to clamping electric wires 100 of different diameters. In addition, the two first inclined surfaces 3111 make the opening of the space formed between the first pressing part 31 and the second pressing part 32 a horn mouth, so that the elastic clamping piece 2 can be more easily clamped between the first pressing part 31 and the second pressing part 32, and the resistance during operation is reduced. Moreover, when the pressing structure 3 moves away from the elastic clamping piece 2, the two first inclined surfaces 3111 can gradually release the first clamping part 21 and the second clamping part 22, so as to prevent the electric wire 100 from suddenly bouncing off and improve the operation safety.

[0074] The two pressing flat surfaces 3112 can ensure the stress area when pressing the first clamping part 21 and the second clamping part 22, and improve the clamping stability of the electric wire 100. Since the two second inclined surfaces 3113 are inclined towards each other in a direction away from the pressing flat surface 3112, the root structure strength of the first pressing part 31 and the second pressing part 32 is higher, so as to ensure the pressing stability.

[0075] In some other embodiments, the first pressing surface 311 and the second pressing surface 321 can also be designed to be inclined towards each other in a direction away from the elastic clamping piece 2. That is, the first pressing surface 311 and the second pressing surface 321 are both inclined surfaces, and by driving the pressing structure 3 to move close to or away from the elastic clamping piece 2, the first clamping part 21 and the second clamping part 22 can be pressed or released, so as to clamp or release the electric wire 100. At the same time, by adjusting the moving distance of the pressing structure 3, the clamping force of the first clamping part 21 and the second clamping part 22 can be changed, and the electric wire 100 of different diameters can be clamped.

[0076] Optionally, referring to Figure 1 , Figure 2 and Figure 3The compression structure 3 further comprises a connecting portion 33, the first compression portion 31 and the second compression portion 32 are arranged at the connecting portion 33 in a spaced manner, and the connecting portion 33 is in sliding connection with the mounting base 1. An adjusting screw 5 is rotatably connected to the mounting base 1, extends along the sliding direction of the compression structure 3, and penetrates through the connecting portion 33 and is in threaded connection with the connecting portion 33. When the adjusting screw 5 is screwed, the compression structure 3 can be driven to slide relative to the mounting base 1. Since the adjusting screw 5 is in threaded connection with the connecting portion 33 and the connecting portion 33 is in sliding connection with the mounting base 1, the compression structure 3 can only move linearly as a whole. Therefore, when the adjusting screw 5 is screwed, the adjusting screw 5 can drive the compression structure 3 to slide, so as to compress or release the first clamping portion 21 and the second clamping portion 22. In addition, the adjusting screw 5 can make the compression structure 3 stop at any position on the sliding path and remain at the current position, without the need for additional fixing operation of the compression structure 3, which simplifies the operation process, and can steplessly adjust the position of the compression structure 3 according to the size of the electric wire 100, has strong flexibility in use, and has a wide application range.

[0077] Referring to Figure 4 The connecting portion 33 is provided with a threaded hole 332, the adjusting screw 5 is in threaded connection with the connecting portion 33 through the threaded hole 332, and one end of the adjusting screw 5 penetrating through the threaded hole 332 is rotatably connected to the mounting base 1. Further, the adjusting screw 5 is provided with an operation portion 51, and the maintenance personnel can screw the adjusting screw 5 through the operation portion 51, which saves time and effort.

[0078] Of course, in other embodiments, a clamping structure or a magnetic attraction structure can be arranged between the compression structure 3 and the mounting base 1 to fix the position of the compression structure 3, so that the compression structure 3 remains at the position of the compression elastic clamping piece 2.

[0079] In the embodiment, the first compression portion 31, the second compression portion 32 and the connecting portion 33 are integrally formed, which simplifies the processing procedure and reduces the production cost. In other embodiments, the first compression portion 31, the second compression portion 32 and the connecting portion 33 can be separately formed and then assembled together.

[0080] Optionally, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4, one end of the insulating cover 4 is provided with a limiting rod 41, the limiting rod 41 is rotatably connected to the mounting base 1 away from the one end of the insulating cover 4, the mounting base 1 is provided with a first limiting groove 111 and a second limiting groove 121, when the insulating cover 4 is in the first position, the limiting rod 41 is clamped and limited in the first limiting groove 111, when the insulating cover 4 is in the second position, the limiting rod 41 is clamped and limited in the second limiting groove 121. Before the wire 100 is disassembled, the limiting rod 41 is limited in the first limiting groove 111, so that the insulating cover 4 can be stably kept in the first position, avoiding interference with the wire disassembly operation. After the wire 100 is disassembled, rotate the insulating cover 4 to make the limiting rod 41 disengage from the first limiting groove 111 and clamp into the second limiting groove 121, so that the insulating cover 4 can be stably kept in the second position, covering the conductive connector 101 of the wire 100, so that the conductive connector 101 is isolated from the outside, ensuring the safety of the maintenance personnel. After the maintenance is completed, rotate the insulating cover 4 back to the first position, the limiting rod 41 disengages from the second limiting groove 121 and clamps into the first limiting groove 111, facilitating the wiring operation. The rotating adjustment of the position of the insulating cover 4 is simple in operation mode and high in working efficiency.

[0081] Referring to Figure 3 and Figure 4 , the mounting base 1 includes a first base 11 and a second base 12 arranged at an angle, the adjusting screw 5 and the first limiting groove 111 are separately arranged on opposite sides of the first base 11, the pressing structure 3 is slidingly connected to the first base 11, the elastic clamping piece 2 and the second limiting groove 121 are separately arranged on opposite sides of the second base 12, and the opening of the first limiting groove 111 is opposite to the opening of the second limiting groove 121. The above structure design is reasonable in layout, which can ensure that the screwing operation of the adjusting screw 5 will not interfere with the rotating operation of the insulating cover 4, and can minimize the overall volume of the wire insulation protection device as much as possible.

[0082] In the embodiment, the first base 11 and the second base 12 are perpendicular, and the insulating cover 4 can be switched from the first position to the second position by rotating 90°. In other embodiments, the angle between the first base 11 and the second base 12 can be set according to actual needs.

[0083] Further, referring to Figure 4 , one end of the second base 12 protrudes on the side of the first base 11 away from the first limiting groove 111, and the adjusting screw 5 is rotatably connected to the protruding part of the second base 12.

[0084] Optionally, the first base 11 of the mounting base 1 is provided with a first elastic block, and the first elastic block is provided with the first limiting slot 111. The second base 12 of the mounting base 1 is provided with a second elastic block, and the second elastic block is provided with the second limiting slot 121. In this way, when the limiting rod 41 is clamped into the first limiting slot 111 or the second limiting slot 121, the first elastic block and the second elastic block can be elastically deformed correspondingly, so that the limiting rod 41 is clamped in the first limiting slot 111 or the second limiting slot 121, and the fixing of the insulating cover 4 in the first position and the second position is further ensured.

[0085] Optionally, the first base 11, the second base 12, the first elastic block and the second elastic block are integrally formed, for example, can be integrally injection molded, the processing technology is simple, and the overall structure is stable and has a long service life.

[0086] Referring to Figure 3 and Figure 4 , the limiting rod 41 is provided with an adapter 42 away from one end of the insulating cover 4. The mounting base 1 is provided with a rotating groove 15, and the adapter 42 is rotatably installed in the rotating groove 15 through a rotating shaft 421, so as to realize the rotating connection of the limiting rod 41 and the mounting base 1. Specifically, the connecting part of the first base 11 and the second base 12 is provided with a first connecting plate 13 and a second connecting plate 14 at intervals, and the rotating groove 15 is formed between the first connecting plate 13 and the second connecting plate 14. The first connecting plate 13 and the second connecting plate 14 are both provided with a rotating hole 16, and the rotating shaft 421 is fixedly arranged on the adapter 42.

The rotating shaft 421 is rotatably matched with the rotating hole 16.

[0087] In this embodiment, the rotating axis of the limiting rod 41 is located at the intersection of the extension line of the first limiting slot 111 and the extension line of the second limiting slot 121. In this way, when the insulating cover 4 is rotated to the first position or the second position, the limiting rod 41 can be completely clamped into the first limiting slot 111 or the second limiting slot 121 correspondingly, so as to ensure the fixing of the insulating cover 4 in the first position and the second position.

The electric wire 100 is clamped into the cover cavity 40 through the end opening 401 and the side opening 402. During the process of rotating the insulating cover 4 from the first position to the second position, the electric wire 100 automatically enters the cover cavity 40 from the end opening 401 and the side opening 402 of the insulating cover 4, and the insulation isolation of the conductive joint 101 is completed, which is convenient to operate.

[0089] In the embodiment, the extension direction of the second limiting groove 121 is consistent with the extension direction of the clamping groove 23, so that when the insulating cover 4 is rotated to the second position, the electric wire 100 is completely hidden in the cover cavity 40 of the insulating cover 4.

[0090] Optionally, the insulating cover 4 has a cover cavity 40, and the depth dimension of the cover cavity 40 is greater than the wire diameter dimension of the electric wire 100. In this way, it can be ensured that the conductive joint 101 of the electric wire 100 can be completely hidden in the cover cavity 40, and the conductive joint 101 has a certain safety distance from the outer edge of the insulating cover 4, preventing the arm or other parts of the maintenance personnel from contacting the conductive joint 101 when the side opening 402 of the cover cavity 40 is touched, improving the insulation isolation performance of the insulating cover 4, and being safer.

[0091] Further, the limiting rod 41 is arranged in a staggered manner with the cover cavity 40, so that when the insulating cover 4 is in the second position, the cover cavity 40 is on the same straight line as the clamping groove 23, so that the electric wire 100 can be completely clamped into the cover cavity 40, and the insulation effect is ensured.

[0092] Referring to Figure 2 and Figure 3 , the sliding space is formed between the first pressing part 31 and the second pressing part 32, and the installation base body 1 is at least partially located in the sliding space. In this way, the structure of the electric wire insulation protection device is more compact, the volume of the device can be reduced, and the device is convenient for the maintenance personnel to carry and use.

[0093] Referring to Figure 4 , one of the installation base body 1 and the pressing structure 3 is provided with a sliding groove 112, and the other is provided with a sliding block 331, and the sliding block 331 and the sliding groove 112 are in sliding cooperation. In the embodiment, the first base body 11 of the installation base body 1 is provided with the sliding groove 112, and the connecting part 33 of the pressing structure 3 is provided with the sliding block 331, and the sliding block 331 and the sliding groove 112 are in sliding cooperation to limit the movement direction of the pressing structure 3, so as to ensure the pressing effect of the first pressing part 31 and the second pressing part 32 on the elastic clamping piece 2. Further, the upper and lower sides of the first base body 11 are both provided with the sliding groove 112, and the connecting part 33 is provided with two sliding blocks 331 which are in one-to-one sliding cooperation with the two sliding grooves 112, so as to improve the sliding stability of the pressing structure 3.

[0094] In other embodiments, a long strip-shaped sliding block 331 extending along the sliding direction of the pressing structure 3 can be arranged on the first base body 11 of the installation base body 1, and a sliding groove 112 can be arranged on the connecting part 33 of the pressing structure 3, and the sliding block 331 and the sliding groove 112 are in sliding cooperation.

[0095] Embodiment two

[0097] S1, adjust the compression structure 3 to the state of not compressing the elastic clamping piece 2, and make the insulation cover 4 in the first position;

[0098] S2, clamp the wire 100 to be insulated into the clamping groove 23 of the elastic clamping piece 2;

[0099] S3, drive the compression structure 3 to move towards the elastic clamping piece 2, so that the first compression part 31 and the second compression part 32 extrude the elastic clamping piece 2 to clamp the wire 100;

[0100] S4, disconnect the connection between the wire 100 and the equipment to be repaired to expose the conductive connector 101 of the wire 100;

[0101] S5, adjust the insulation cover 4 to the second position to cover the conductive connector 101 of the wire 100.

[0102] The wire insulation protection method first fixes the wire 100 before disassembling the wire 100, at this time the maintenance personnel operate the part of the wire 100 with an insulation layer, which can avoid contacting the live part, thereby preventing electric shock accidents. And when covering the conductive connector 101 of the wire 100, the maintenance personnel only need to touch the insulation cover 4, which further reduces the risk of electric shock. The existence of the insulation cover 4 can also prevent the contact short circuit between the wire 100 and the wire 100, and ensure the stable operation of the power system.

[0103] The wire insulation protection method provided by the embodiment can complete the insulation isolation of the wire 100 by clamping the wire 100, screwing the adjusting screw 5, and rotating the insulation cover 4, which is very convenient to operate and does not require other professional tools, thereby improving the work efficiency. Moreover, the wire insulation protection device can be applied to wires 100 of different specifications, and the clamping force of the elastic clamping piece 2 can be adjusted by screwing the adjusting screw 5, so the application range is wide.
