[0059] Embodiment 1

[0060] like Figures 1 to 4 As shown, this embodiment provides a wire insulation protection device, which can prevent electric shock during maintenance and repair, ensure operation safety, improve operation efficiency, and reduce maintenance and repair costs. The wire insulation protection device includes a mounting base 1, an elastic clamping member 2, a clamping structure 3, and an insulation cover 4.

[0061] Among them, see Figure 1 and Figure 2The elastic clamp 2 is arranged on the mounting base 1. The elastic clamp 2 has a clamping groove 23. The clamping groove 23 is used to clamp the wire 100 to be insulated. The clamping structure 3 is movably arranged on the mounting base 1. The clamping structure 3 includes a first clamping portion 31 and a second clamping portion 32 respectively arranged on both sides of the elastic clamp 2. When the clamping structure 3 moves toward the direction close to the elastic clamp 2, the first clamping portion 31 and the second clamping portion 32 can squeeze the elastic clamp 2 to clamp the wire 100 in the clamping groove 23. The insulating cover 4 is movably connected to the mounting base 1 and has a first position and a second position. In the first position, the insulating cover 4 avoids the conductive joint 101 (such as Figure 1 In the second position, the insulating cover 4 is disposed outside the conductive connector 101 of the wire 100 (as shown); Figure 2 shown).

[0062] The wire insulation protection device provided in this embodiment, when performing insulation protection on the wire 100 to be insulated, before removing the wire 100 (wire 100 to be insulated) connected to the equipment to be repaired (such as an electric meter), first ensure that the insulation cover 4 is in the first position, does not hinder the subsequent removal of the wire 100, and the first pressing part 31 and the second pressing part 32 of the pressing structure 3 do not press the elastic clamp 2, which is convenient for the subsequent fixing of the wire 100. Afterwards, the part of the wire 100 with the insulation layer is inserted into the clamping groove 23 of the elastic clamp 2, and the clamping structure 3 is driven to move in the direction close to the elastic clamp 2 until the first pressing part 31 and the second pressing part 32 squeeze the elastic clamp 2 to clamp the wire 100, so as to fix the position of the wire 100.

[0063] Then, the connection between the wire 100 and the equipment to be repaired is removed to expose the conductive joint 101 of the wire 100, and then the insulating cover 4 is operated to switch it from the first position to the second position. The insulating cover 4 covers and wraps the conductive joint 101 of the wire 100, thereby isolating the conductive joint 101 of the wire 100 from the outside world, thereby achieving insulation protection for the wire 100. At this time, when the maintenance personnel perform maintenance on the equipment to be repaired, electric shock can be prevented, thereby ensuring the personal safety of the maintenance personnel. At the same time, the existence of the insulating cover 4 can also prevent the wires 100 from contacting and short-circuiting with each other, thereby ensuring the stable operation of the power system.

[0064] After the inspection and maintenance is completed, the insulation cover 4 is adjusted from the second position to the first position to perform wiring operations. After the wiring is completed, the clamping structure 3 is driven to move in the opposite direction so that the first clamping portion 31 and the second clamping portion 32 release the elastic clamping member 2, and finally, the wire 100 is removed from the clamping groove 23 of the elastic clamping member 2. When the wire insulation protection device is used to perform insulation protection on the wire 100, only simple clamping and covering operations are required, and no other auxiliary tools are required. The operation is simple, and the inspection and maintenance efficiency can be improved, thereby reducing the inspection and maintenance costs.

[0065] Optionally, the mounting base 1, the elastic clamp 2, the pressing structure 3 and the insulating cover 4 are all made of insulating materials. This arrangement can improve the insulation performance of the entire device, effectively prevent electric shock, and improve the safety of use. Exemplarily, the insulating material is a plastic with a certain elasticity, which can not only ensure the insulation effect, but also make the overall structure strong, durable, and easy to produce and maintain.

[0066] Optionally, see Figure 1 , Figure 2 and Figure 3 The elastic clamp 2 includes a first clamping portion 21 and a second clamping portion 22 that are spaced apart, and a clamping groove 23 is formed between the first clamping portion 21 and the second clamping portion 22. When the clamping structure 3 moves relative to the mounting base 1, the first clamping portion 21 and the second clamping portion 22 approach or move away from each other. When the clamping structure 3 is driven to approach the elastic clamp 2, the first clamping portion 31 and the second clamping portion 32 jointly squeeze the elastic clamp 2, so that the first clamping portion 21 and the second clamping portion 22 approach each other, thereby clamping the wire 100. When the clamping structure 3 is driven to move away from the elastic clamp 2, the force of the first clamping portion 31 and the second clamping portion 32 on the elastic clamp 2 is reduced, and the first clamping portion 21 and the second clamping portion 22 can move away from each other, thereby releasing the wire 100, and facilitating the operation of the wire 100 to detach from the elastic clamp 2. By operating the clamping structure 3 to move forward or backward, the first clamping portion 21 and the second clamping portion 22 can clamp or release the wire 100, which can reduce the difficulty of operation, facilitate on-site operation of maintenance personnel, and improve work efficiency.

[0067] In this embodiment, the first clamping portion 21 and the second clamping portion 22 are both made of flexible materials and can produce elastic deformation. When the pressing structure 3 moves close to the elastic clamping member 2, the first clamping portion 21 and the second clamping portion 22 approach each other and produce elastic deformation, accumulating elastic potential energy. When the pressing structure 3 moves away from the elastic clamping member 2, the first clamping portion 21 and the second clamping portion 22 move away from each other under the action of their own elastic force, automatically releasing the wire 100 without additional operation, further simplifying the operation steps of the insulation protection of the wire 100.

[0068] Furthermore, the first clamping portion 21 and the second clamping portion 22 are integrally formed components, and the overall cross-sectional shape is C-shaped, which can simplify the structural design and reduce the processing cost. For example, the elastic clamping member 2 is made of rubber material as a whole, or the elastic clamping member 2 is made of elastically deformable plastic.

[0069] In other embodiments, the first clamping portion 21 and the second clamping portion 22 may also be formed separately, and one end of both are rotatably connected to the mounting base 1, and a torsion spring is installed. When the clamping structure 3 moves away from the first clamping portion 21 and the second clamping portion 22, the first clamping portion 21 and the second clamping portion 22 are moved away from each other under the elastic force of the torsion spring, thereby loosening the wire 100.

[0070] Optionally, see Figure 2 , Figure 3 and Figure 4 The first clamping portion 21 and the second clamping portion 22 are both provided with a push-up inclined surface 24 on the side facing away from each other, and the push-up inclined surface 24 is inclined in the direction facing away from the clamping groove 23. When the clamping structure 3 moves relative to the mounting base 1, the first clamping portion 31 slides with the push-up inclined surface 24 of the first clamping portion 21, and the second clamping portion 32 slides with the push-up inclined surface 24 of the second clamping portion 22. Since the push-up inclined surface 24 is inclined away from the clamping groove 23, when the clamping structure 3 moves close to the elastic clamping member 2, the first clamping portion 31 generates an inward thrust on the first clamping portion 21, and the second clamping portion 32 generates an inward thrust on the second clamping portion 22, so that the first clamping portion 21 and the second clamping portion 22 are brought close to each other, thereby clamping the wire 100.

[0071] In addition, the setting of the push slope 24 can adjust the moving distance of the clamping structure 3 according to the wire diameter of the wire 100, so as to change the distance between the first clamping part 21 and the second clamping part 22, thereby changing the clamping force of the first clamping part 21 and the second clamping part 22, and can adapt to clamping wires 100 with different wire diameters, expand the use range of the wire insulation protection device, and have stronger versatility.

[0072] Optionally, see Figure 2 and Figure 3 The first pressing portion 31 has a first pressing surface 311 on one side facing the second pressing portion 32, and the second pressing portion 32 has a second pressing surface 321 on one side facing the first pressing portion 31. Both the first pressing surface 311 and the second pressing surface 321 can contact the elastic clamping member 2. When the clamping structure 3 is driven to move relative to the mounting base 1, the first pressing surface 311 and the second pressing surface 321 work together to press the elastic clamping member 2, so that the elastic clamping member 2 clamps the wire 100 in the clamping groove 23.

[0073] See also Figure 3The first pressing surface 311 and the second pressing surface 321 each include a first inclined surface 3111, a pressing plane 3112 and a second inclined surface 3113 connected in sequence. The two first inclined surfaces 3111 are inclined in a direction away from the pressing plane 3112 and in a direction away from each other, and the two second inclined surfaces 3113 are inclined in a direction away from the pressing plane 3112 and in a direction close to each other. The two first inclined surfaces 3111 can contact the push inclined surface 24 of the first clamping part 21 and the push inclined surface 24 of the second clamping part 22 respectively. By adjusting the moving distance of the pressing structure 3, the contact position of the first inclined surface 3111 and the push inclined surface 24 can be changed, thereby changing the clamping force of the first clamping part 21 and the second clamping part 22, so as to adapt to clamping wires 100 of different wire diameters. In addition, the two first inclined surfaces 3111 are arranged so that the opening of the space formed between the first pressing part 31 and the second pressing part 32 is a bell mouth, which can make it easier for the elastic clamping member 2 to be inserted between the first pressing part 31 and the second pressing part 32, thereby reducing the resistance during operation. Moreover, when the pressing structure 3 moves away from the elastic clamping member 2, the two first inclined surfaces 3111 can gradually release the first clamping part 21 and the second clamping part 22, thereby preventing the wire 100 from suddenly bouncing off, thereby improving the safety of operation.

[0074] When the two pressing planes 3112 cooperate to press the first clamping portion 21 and the second clamping portion 22, the force bearing area can be ensured, and the clamping stability of the wire 100 can be improved. Since the two second inclined surfaces 3113 are inclined close to each other in a direction away from the pressing planes 3112, the root structure strength of the first pressing portion 31 and the second pressing portion 32 is higher, thereby ensuring the pressing stability.

[0075] In some other embodiments, it can also be designed that the first pressing surface 311 and the second pressing surface 321 are inclined toward each other in the direction away from the elastic clamping member 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 approach or move away from the elastic clamping member 2, the first clamping portion 21 and the second clamping portion 22 can also be pressed or loosened to achieve clamping or loosening of the wire 100. At the same time, by adjusting the moving distance of the pressing structure 3, the clamping force of the first clamping portion 21 and the second clamping portion 22 can be changed to adapt to clamping wires 100 of different wire diameters.

[0076] Optionally, see Figure 1 , Figure 2 and Figure 3The clamping structure 3 also includes a connecting portion 33, a first clamping portion 31 and a second clamping portion 32 are arranged at intervals on the connecting portion 33, and the connecting portion 33 is slidably connected to the mounting base 1. An adjusting screw 5 is rotatably connected to the mounting base 1, and the adjusting screw 5 extends along the sliding direction of the clamping structure 3, and the adjusting screw 5 passes through the connecting portion 33 and is threadedly matched with the connecting portion 33. When the adjusting screw 5 is screwed, the clamping structure 3 can be driven to slide relative to the mounting base 1. Since the adjusting screw 5 is threadedly matched with the connecting portion 33, and the connecting portion 33 is slidably connected to the mounting base 1, the clamping structure 3 as a whole can only move in a straight line. Therefore, when the adjusting screw 5 is screwed, the adjusting screw 5 can drive the clamping structure 3 to slide, so that the first clamping portion 31 and the second clamping portion 32 can clamp or loosen the first clamping portion 21 and the second clamping portion 22. In addition, the setting of the adjusting screw 5 can make the clamping structure 3 stay at any position on its sliding path and maintain the current position, without the need for additional fixing operation of the clamping structure 3, thereby simplifying the operation process. At the same time, the position of the clamping structure 3 can be steplessly adjusted according to the size of the wire 100, which has strong flexibility in use and a wide range of applications.

[0077] See also Figure 4 The connection part 33 is provided with a threaded hole 332, and the adjusting screw 5 is threadedly matched with the connection part 33 through the threaded hole 332. One end of the adjusting screw 5 passing through the threaded hole 332 is rotatably connected to the mounting base 1. Furthermore, an operating part 51 is provided on the adjusting screw 5, and the maintenance personnel can screw the adjusting screw 5 through the operating part 51, which saves time and effort.

[0078] Of course, in other embodiments, a snap-fit ​​structure, a magnetic structure, etc. may be provided between the clamping structure 3 and the mounting base 1 to fix the position of the clamping structure 3 so that the clamping structure 3 remains at the position of the clamping elastic clamp 2 .

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

[0080] Optionally, see Figure 1 , Figure 2 , Figure 3 and Figure 4A limiting rod 41 is provided at one end of the insulating cover 4, and an end of the limiting rod 41 away from the insulating cover 4 is rotatably connected to the mounting base 1. 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 limited to the first limiting groove 111, and when the insulating cover 4 is in the second position, the limiting rod 41 is limited to the second limiting groove 121. Before disassembling the wire 100, the limiting rod 41 is limited by the first limiting groove 111, so that the insulating cover 4 can be stably maintained in the first position to avoid interference with the wire removal operation. After the wire 100 is disassembled, the insulating cover 4 is rotated to make the limiting rod 41 disengage from the first limiting groove 111 and snap into the second limiting groove 121, so that the insulating cover 4 can be stably maintained in the second position, so as to cover the conductive joint 101 of the wire 100, so that the conductive joint 101 is insulated and isolated from the outside, and the maintenance personnel can ensure the safety of the operation. After the inspection is completed, the insulating cover 4 is rotated back to the first position, and the limiting rod 41 is separated from the second limiting groove 121 and inserted into the first limiting groove 111, so as to facilitate the wiring operation. The method of rotating and adjusting the position of the insulating cover 4 is simple to operate and has high working efficiency.

[0081] See also 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 respectively arranged on opposite sides of the first base 11, the pressing structure 3 is slidably connected to the first base 11, the elastic clamping member 2 and the second limiting groove 121 are respectively 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 structural design has a reasonable layout, which can ensure that the screwing operation of the adjusting screw 5 will not interfere with the rotation operation of the insulating cover 4, and can reduce the overall volume of the wire insulation protection device as much as possible.

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

[0083] Further, see Figure 4 One end of the second base body 12 is protruded on a side of the first base body 11 facing away from the first limiting groove 111 , and the adjusting screw rod 5 is rotatably connected to the protruding portion of the second base body 12 .

[0084] Optionally, a first elastic block is provided on the first base 11 of the mounting base 1, and the first elastic block is provided with the above-mentioned first limiting groove 111, and a second elastic block is provided on the second base 12 of the mounting base 1, and the second elastic block is provided with the above-mentioned second limiting groove 121. With such a configuration, when the limiting rod 41 is inserted into the first limiting groove 111 or the second limiting groove 121, the first elastic block and the second elastic block can generate elastic deformation accordingly, so that the limiting rod 41 is clamped in the first limiting groove 111 or the second limiting groove 121, further ensuring that the insulating cover 4 is firmly fixed in the first position and the second position.

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

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

[0087] In this embodiment, the rotation axis of the limit rod 41 is located at the intersection of the extension line of the first limit groove 111 and the extension line of the second limit groove 121. In this way, when the insulating cover 4 rotates to the first position or the second position, the limit rod 41 can be completely inserted into the first limit groove 111 or the second limit groove 121 accordingly, ensuring that the insulating cover 4 is firmly fixed in the first position and the second position.

[0088] Optionally, see Figure 1 and Figure 2 The insulating cover 4 has a cover cavity 40, one end of the cover cavity 40 is closed, and the other end is open to form an end opening 401, and the cover cavity 40 has a side opening 402 connected to the end opening 401, and the wire 100 is inserted into the cover cavity 40 through the end opening 401 and the side opening 402. When the insulating cover 4 is rotated from the first position to the second position, the wire 100 automatically enters the cover cavity 40 through the end opening 401 and the side opening 402 of the insulating cover 4, completing the insulation isolation of the conductive joint 101, and the operation is convenient.

[0089] In this 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 rotates to the second position, the wire 100 is just 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 of the cover cavity 40 is greater than the diameter of the wire 100. In this way, it can be ensured that the conductive connector 101 of the wire 100 can be completely hidden in the cover cavity 40, and there is a certain safety distance between the conductive connector 101 and the outer edge of the insulating cover 4, so as to prevent the arms and other parts of the maintenance personnel from touching the side opening 402 of the cover cavity 40 and contacting the conductive connector 101, thereby improving the insulation isolation performance of the insulating cover 4 and making it safer.

[0091] Furthermore, the limiting rod 41 and the covering cavity 40 are staggered to ensure that in the second position, the covering cavity 40 and the clamping groove 23 are in the same straight line, so that the wire 100 can be completely inserted into the covering cavity 40 to ensure the insulation effect.

[0092] See also Figure 2 and Figure 3 A sliding space is formed between the first pressing part 31 and the second pressing part 32, and the mounting base 1 is at least partially located in the sliding space. This arrangement makes the structure of the wire insulation protection device more compact, can reduce the size of the device, and is convenient for maintenance personnel to carry and use.

[0093] See also Figure 4 , one of the mounting base 1 and the clamping structure 3 is provided with a slide groove 112, and the other is provided with a slider 331, and the slider 331 is slidably matched with the slide groove 112. In this embodiment, the slide groove 112 is provided on the first base 11 of the mounting base 1, and the slider 331 is provided on the connecting portion 33 of the clamping structure 3. The sliding match between the slider 331 and the slide groove 112 can limit the moving direction of the clamping structure 3, and ensure the clamping effect of the first clamping portion 31 and the second clamping portion 32 on the elastic clamping member 2. Further, the slide grooves 112 are provided on both the upper and lower sides of the first base 11, and two sliders 331 are arranged at intervals on the connecting portion 33. The two sliders 331 are slidably matched with the two slide grooves 112 in a one-to-one correspondence, thereby improving the sliding stability of the clamping structure 3.

[0094] In other embodiments, a long strip slider 331 extending along the sliding direction of the clamping structure 3 may be provided on the first base 11 of the mounting base 1, and a slide groove 112 may be provided on the connecting portion 33 of the clamping structure 3, and the slider 331 may slide in cooperation with the slide groove 112.

[0095] Embodiment 2

[0096] like Figure 5As shown, this embodiment provides a wire insulation protection method, which uses the wire insulation protection device as described in the first embodiment to perform insulation treatment on the wire 100 to be insulated, including the following steps:

[0097] S1, adjusting the pressing structure 3 to a state where the elastic clamping member 2 is not pressed, and placing the insulating cover 4 in the first position;

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

[0099] S3, driving the clamping structure 3 to move toward the direction close to the elastic clamping member 2, so that the first clamping portion 31 and the second clamping portion 32 squeeze the elastic clamping member 2 to clamp the wire 100;

[0100] S4, disconnecting the electric wire 100 from the equipment to be repaired to expose the conductive connector 101 of the electric wire 100;

[0101] S5 , adjusting the insulating cover 4 to the second position, so that the insulating cover 4 covers the conductive connector 101 of the electric wire 100 .

[0102] The wire insulation protection method fixes the wire 100 before removing the wire 100. At this time, the maintenance personnel operate the part of the wire 100 with the insulation layer, which can avoid contacting the live part, thereby preventing electric shock accidents. In addition, when the conductive connector 101 of the wire 100 is covered, the maintenance personnel only need to touch the insulation cover 4, further reducing the risk of electric shock. The existence of the insulation cover 4 can also prevent the wires 100 from short-circuiting due to contact, thereby ensuring the stable operation of the power system.

[0103] In the wire insulation protection method provided in this embodiment, when the wire 100 is insulated by the wire insulation protection device, the maintenance personnel only need to clamp the wire 100, screw the adjustment screw 5, and rotate the insulation cover 4 to complete the insulation isolation of the wire 100. The operation is very convenient and no other professional tools are required, which improves the work efficiency. In addition, the wire insulation protection device can be applied to wires 100 of different specifications, and the clamping force of the elastic clamp 2 can be adjusted by screwing the adjustment screw 5, so it has a wide range of applications.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
