Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for live-line working, and specifically to a protective conduit for live-line working wires. Background Technology

[0002] In the process of power maintenance, most of the time it is necessary for operators to perform live work. In this process, how to insulate and shield the live wires is directly related to the personal safety of the operators. Therefore, it is necessary to use wire protection pipes to insulate and shield the live wires.

[0003] However, in the current design of conductor protection pipes, the length of a single section is usually fixed. This means that when the live conductor that needs to be shielded is long, such as an overhead conductor, a single section of conductor protection pipe may not be long enough and multiple sections may need to be spliced ​​together. When multiple sections of existing conductor protection pipes are spliced ​​together, there will be obvious gaps at the splice points, which will cause the insulation reliability to be compromised. Utility Model Content

[0004] The purpose of this utility model is to provide a protective conduit for live-line work in order to solve the above problems. By means of plugging and snapping the large end connector with the small end connector of another wire cover, the two wire covers can be quickly connected together and the obvious gap at the connection point can be avoided. See the following description for details.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a protective conduit for live-line work, including a conductor cover and a large-end connector. Both ends of the conductor cover are provided with small-end connectors. The large-end connector is sleeved and fixed to the outside of the small-end connector at one end. The two conductor covers can be connected together by inserting and snapping the large-end connector with the small-end connector of the other conductor cover.

[0007] Both the conductor cover and the large end connector have through slots along the axial direction. The conductor cover extends and is fixed to two sides of the through slot with a toothed part I that can interlock with each other on both sides. The large end connector extends and is fixed to two sides of the through slot with a toothed part II that can interlock with each other on both sides. This is to tighten the through slot and increase the creepage distance by interlocking the two toothed parts on both sides.

[0008] Preferably, the small end connector is an anti-detachment platform disposed on the periphery of the end of the conductor cover, and the inner circumference of the large end connector is provided with two slots. The large end connector is sleeved on the periphery of the end of the conductor cover by means of the slots and the anti-detachment platform. At the same time, the inner circumference of the large end connector and the periphery of the conductor cover are fixedly connected by welding.

[0009] Preferably, the outer periphery of the anti-detachment platform has a circumferentially formed bevel for easy insertion into the slot.

[0010] Preferably, the outer end of the large end connector is a flared sleeve, and the outer end opening of the flared sleeve is a flared guide port for guiding the small end connector of the other wire cover to be inserted into the connection.

[0011] Preferably, both the first and second meshing portions are provided with at least five layers staggered on both sides.

[0012] Preferably, the outer cover of the large end connector is provided with a reset cover, and both sides of the reset cover extend to the through-slit of the large end connector.

[0013] Preferably, the inner circumference of the reset cover is fixedly connected to the outer circumference of the large end connector by welding.

[0014] Preferably, auxiliary reset pieces are provided on both sides of the through-slit on the outside of the wire cover.

[0015] In practical application, the above-mentioned protective conduit for live-line work utilizes a small-end connector at both ends of the conductor cover. The large-end connector is fixed to the outside of the small-end connector at one end of the conductor cover by a locking mechanism between the anti-detachment plate at the end of the conductor cover and the slot within the large-end connector, and by welding. Furthermore, by inserting the large-end connector into the small-end connector of another conductor cover, two conductor covers can be quickly joined together without significant gaps. The connection and expansion operation for multiple conductor covers is simple and easy to implement, ensuring reliable insulation and shielding capabilities during use. Since both the conductor cover and the large-end connector have axially extending slots, and the conductor cover has a toothed portion (I) extending and fixed to both sides of the slot, capable of interlocking, and the large-end connector has a toothed portion (II) extending and fixed to both sides of the slot, capable of interlocking, the connection can be further facilitated by prying open the toothed portion (I) and... The second type of meshing part allows the through-slit to be opened, enabling the conductor cover and the large-end connector to be smoothly fitted over the conductor to be insulated. After the conductor is covered, the interlocking of both sides of the first and second meshing parts tightly tightens the through-slit of the conductor cover and the large-end connector, increasing the creepage distance. This achieves stable insulation protection for the live conductor. Furthermore, the opening, fitting, and tightening mechanism of the conductor cover and the large-end connector for the live conductor is simple and easy to operate. The large-end connector is fixed to the outside by welding with the reset cover, and both sides of the reset cover extend to the through-slit of the large-end connector. The wire cover is provided with auxiliary reset pieces extending to both sides of the through-slit. With the elastic tightening effect of the reset cover and the auxiliary reset pieces, the first and second meshing parts can be stably tightened and prevented from opening when they are interleaved, ensuring that the first and second meshing parts can reliably increase the creepage distance in use.

[0016] The beneficial effects are as follows: 1. Both ends of the wire cover of this utility model are provided with small end connectors. By using the anti-detachment platform at the end of the wire cover to engage with the slot of the inner circumference of the large end connector and by welding to fix it, the large end connector can be limited and fixed outside the small end connector at one end of the wire cover. Then, by using the large end connector to engage with the small end connector of another wire cover, the two wire covers can be quickly connected together and avoid obvious gaps at the connection position. The connection and expansion operation of multiple wire covers is simple and easy to implement, ensuring that the wire cover has reliable insulation and shielding capabilities when in use.

[0017] 2. Both the conductor cover and the large-end connector have through slots along the axial direction. The conductor cover has teeth that can interlock on both sides of the through slot. The large-end connector has teeth that can interlock on both sides of the through slot. The through slot can be opened by prying open the teeth and teeth, so that the conductor cover and the large-end connector can be smoothly put on the outside of the conductor to be insulated. After the conductor is covered, the through slot of the conductor cover and the large-end connector can be tightly tightened by the interlocking of the teeth and teeth, and the creepage distance can be increased. This can achieve stable insulation protection for the live conductor. The opening and closing of the conductor cover and the large-end connector for the live conductor is simple and easy to operate.

[0018] 3. A reset cover is fixed to the outside of the large end connector by welding, and both sides of the reset cover extend to the through seam of the large end connector. Auxiliary reset pieces are extended on both sides of the through seam outside the conductor cover. With the elastic tightening effect of the reset cover and the auxiliary reset pieces, the first and second teeth can be stably tightened and prevented from opening when they are interleaved, ensuring that the first and second teeth can reliably increase the creepage distance under the use condition.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] See Figures 1-8 As shown, this utility model provides a protective conduit for live-line work, including a conductor cover 2 and a large-end connector 3. Both ends of the conductor cover 2 are provided with small-end connectors 1. A large-end connector 3 is fixedly sleeved on the outside of the small-end connector 1 at one end. With this arrangement, the two conductor covers 2 can be connected together by inserting and snapping the large-end connector 3 with the small-end connector 1 of another conductor cover 2, and obvious gaps can be avoided at the connection position. The connection and expansion operation of multiple conductor covers 2 is simple and easy to implement.

[0032] See Figures 1-8 As shown, both the conductor cover 2 and the large-end connector 3 have through slits 7 along the axial direction. At the same time, the conductor cover 2 has teeth 5 extending and fixed to both sides of the through slit 7, which can interlock with each other on both sides. The large-end connector 3 has teeth 6 extending and fixed to both sides of the through slit 7, which can interlock with each other on both sides. The purpose of this arrangement is to tighten the through slit 7 and increase the creepage distance by interlocking the teeth 5 and teeth 6 on both sides. This can achieve stable insulation protection for the live conductor. At the same time, the opening and closing of the conductor cover 2 and the large-end connector 3 for the live conductor is simple and easy to operate.

[0033] See Figures 1-3As shown, the conductor cover 2, small end connector 1, and large end connector 3 have been optimized as follows. Specifically, the small end connector 1 is an anti-detachment platform 102 set on the outer periphery of the end of the conductor cover 2. The inner periphery of the large end connector 3 is provided with two slots 304. The large end connector 3 is fitted onto the outer periphery of the end of the conductor cover 2 by snapping the anti-detachment platform 102 into the slots 304. At the same time, the inner periphery of the large end connector 3 and the outer periphery of the conductor cover 2 are fixed together by welding. With this setting, the small end connector 1 and the large end connector 3 are prevented from accidentally separating from each other after insertion by the anti-detachment platform 102 snapping into the slots 304. At the same time, welding can also make the large end connector 3 stably fixed to the outside of one end of the conductor cover 2. Furthermore, the periphery of the anti-detachment platform 102 is provided with a circumferentially circumferentially opening for easy insertion and snapping into the slot 304, so that when the anti-detachment platform 102 is snapped into the slot 304, the anti-detachment platform 102 can have good passability with the help of the circumferential opening 101.

[0034] See Figures 1-8 As shown, the outer end of the large-end connector 3 is a flared sleeve 301, and the outer opening of the flared sleeve 301 is a flared guide port 303 for guiding the small-end connector 1 of another conductor cover 2 to be inserted into the large-end connector 3. With this configuration, the small-end connector 1 of the other conductor cover 2 can be smoothly inserted into the large-end connector 3 by means of the flared guide port 303. Optionally, both the first toothed part 5 and the second toothed part 6 are staggered with at least five layers on both sides so that both the first toothed part 5 and the second toothed part 6 have creepage distances that meet the insulation class requirements. Furthermore, the outer cover of the large end connector 3 is provided with a reset cover 302, and both sides of the reset cover 302 extend to the through slot 7 of the large end connector 3. The inner circumference of the reset cover 302 is fixedly connected to the outer circumference of the large end connector 3 by welding. The outer side of the wire cover 2 is provided with auxiliary reset pieces 4 on both sides of the through slot 7. Preferably, the reset cover 302 and the auxiliary reset pieces 4 are in a spring-loaded and tightened state in their natural state. With this arrangement, the reset cover 302 can be stably fixed to the outside of the large end connector 3 by welding. At the same time, the elastic tightening effect of the reset cover 302 and the auxiliary reset pieces 4 can be used to achieve stable tightening and prevent opening when the first tooth and the second tooth 6 are interlocked.

[0035] With the above structure, in practical use, since both ends of the conductor cover 2 are provided with small end connectors 1, and the anti-detachment platform 102 at the end of the conductor cover 2 is engaged with the slot 304 inside the large end connector 3 and fixed by welding, the large end connector 3 can be limited and fixed outside the small end connector 1 at one end of the conductor cover 2. Then, by inserting and engaging the large end connector 3 with the small end connector 1 of another conductor cover 2, the two conductor covers 2 can be quickly connected together without obvious gaps at the connection point. The connection and expansion operation of multiple conductor covers 2 is simple and easy to implement, ensuring that the conductor cover 2 has reliable insulation and shielding capabilities during use. Since both the conductor cover 2 and the large end connector 3 have through slots 7 along the axial direction, and the conductor cover 2 has toothed parts 5 that can interlock on both sides of the through slot 7, and the large end connector 3 has toothed parts 6 that can interlock on both sides of the through slot 7, then by prying open the toothed parts 5 and 6, the conductor cover 2 can quickly connect the two conductor covers together without obvious gaps at the connection point. This method allows the through-slit 7 to be opened, enabling the conductor cover 2 and large-end connector 3 to be smoothly fitted over the conductor to be insulated. After the conductor is covered, the through-slit 7 of the conductor cover 2 and large-end connector 3 is tightly tightened by the interlocking of both sides of the toothed parts 5 and 6, increasing the creepage distance. This achieves stable insulation protection for the live conductor. Furthermore, the opening, fitting, and tightening mechanism of the conductor cover 2 and large-end connector 3 is simple and easy to operate. A reset cover 302 is fixed to the outside of the large end connector 3 by welding, and both sides of the reset cover 302 extend to the through slit 7 of the large end connector 3. Auxiliary reset pieces 4 are provided on both sides of the through slit 7 on the outside of the wire cover 2. With the elastic tightening effect of the reset cover 302 and the auxiliary reset pieces 4, the first toothed part 5 and the second toothed part 6 can be stably tightened and prevented from opening when they are interleaved, ensuring that the first toothed part 5 and the second toothed part 6 can reliably increase the creepage distance in use.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
