Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for live-line work, and specifically to a conductor insulation shield. Background Technology

[0002] When performing live-line maintenance on overhead power distribution lines, strict insulation shielding of the main line being worked on is required under safety regulations to meet the required operational safety standards. Traditionally, operators use insulating blankets to shield the lines. However, arranging these blankets is complex, as a single blanket can only cover a limited length of line, requiring multiple blankets to meet the insulation shielding requirements of the work area. This results in low overall work efficiency and high labor intensity.

[0003] Patent application CN201420258823.X discloses a conductor insulation shielding tube, which includes a shielding tube body and an overlapping sleeve for connecting two shielding tube bodies. The shielding tube body includes an annular sleeve and two protective wing plates. The annular sleeve has a notch along its length. The two protective wing plates are respectively fixed to two free ends of the annular sleeve along the length of its notch. This insulation shielding tube is simply fitted onto the outer periphery of the line, and adjacent shielding tube bodies are connected by the overlapping sleeve. It is more convenient to use than insulating blankets, but the notch for inserting or removing conductors reduces the insulation effect somewhat. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a conductor insulation shield, which is more convenient to use than insulation blankets, improves work efficiency, and offers better overall insulation and higher safety.

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

[0006] A conductor insulation shield includes an insulating tube with a notch extending along its length on its radial side. The insulating tube has two free ends located on either side of the notch, and each free end is connected to a first encapsulation strip. The first encapsulation strip includes a first encapsulation plate connected to the outside of the insulating tube. The length direction of the first encapsulation plate is perpendicular to the diameter section of the insulating tube. A plurality of first encapsulation teeth arranged along the width direction of the first encapsulation plate are connected to the side of the first encapsulation plate near the notch. A first encapsulation groove is formed between adjacent first encapsulation teeth, and two corresponding first encapsulation strips can engage with each other through the first encapsulation teeth and the first encapsulation groove.

[0007] This invention achieves insulation and shielding by using an insulating tube fitted around the outer periphery of the conductor. The conductor can be inserted into the insulating tube through a notch on the side of the insulating tube, making operation convenient and efficient. Each of the two free ends of the insulating tube is connected to a first sealing strip, which has alternating first sealing teeth and first sealing grooves. The two first sealing strips can mesh with each other through the tooth and groove structure, so that the notch of the insulating tube is closed. Furthermore, the creepage distance from the inside of the insulating tube to the radial outside of the insulating tube is greatly increased, effectively improving operational safety.

[0008] Furthermore, the conductor insulation shield also includes a support strip, which includes a support plate connected to the outside of the insulation tube. The end of the support plate away from the insulation tube is in movable contact with the side of the first encapsulation plate away from the notch in the insulation tube.

[0009] Furthermore, the support bar also includes support teeth connected to the side of the support plate near the first encapsulation plate, and the support teeth movably abut against the side of the first encapsulation plate away from the insulating tube notch.

[0010] Furthermore, the conductor insulation shield also includes a connecting sleeve, the two ends of which form connecting ports for the insertion of the insulating tube in the axial direction, the radial side of the connecting sleeve is provided with a sleeve notch extending along its own length direction, and the connecting sleeve has two sleeve free ends located on both sides of the sleeve notch respectively.

[0011] Furthermore, the connecting sleeve also includes a second encapsulation strip. Each free end of the sleeve is connected to a second encapsulation strip. The second encapsulation strip includes a second encapsulation plate connected to the outside of the connecting sleeve. The side of the second encapsulation plate near the sleeve notch is connected to a plurality of second encapsulation teeth. A second encapsulation groove is formed between adjacent second encapsulation teeth. Two opposing second encapsulation strips can engage with each other through the second encapsulation teeth and the second encapsulation groove.

[0012] Furthermore, the conductor insulation shield also includes a protective outer shell, which is movably fitted onto the outside of the connecting sleeve.

[0013] Furthermore, a protruding limiting block is connected to the outer side of the insulating tube, and the limiting block is located near the end of the insulating tube.

[0014] Furthermore, the connection port has a radially inward protruding limiting notch that mates with the outer wall of the insulating tube.

[0015] Furthermore, the connection port also includes a guide flare disposed at the outer end of the limiting constriction, the inner diameter of the guide flare gradually increasing in the direction away from the limiting constriction.

[0016] Furthermore, a partition is provided in the middle of the connecting sleeve, and a through hole is provided in the middle of the partition. The end of the insulating tube can abut against the partition and make the through hole communicate with the opening of the insulating tube.

[0017] The following beneficial effects can be achieved by applying this utility model:

[0018] 1. This utility model achieves insulation and shielding effect by using an insulating tube fitted around the outer periphery of the conductor. The conductor can be inserted into the insulating tube through the notch on the side of the insulating tube, which is convenient to operate and has high work efficiency.

Detailed Implementation

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0028] Reference Figures 1-5 This embodiment provides a conductor insulation shield, which includes an insulating tube 1. The insulating tube has a notch 11 extending along its length on its radial side. The insulating tube has two free ends 12 located on either side of the notch 11. Each free end 12 is connected to a first encapsulation strip 13. The first encapsulation strip 13 includes a first encapsulation plate 131 connected to the outside of the insulating tube. The length direction of the first encapsulation plate 131 is perpendicular to the diameter of the insulating tube. A plurality of first encapsulation teeth 132, arranged along the width direction of the first encapsulation plate 131, are connected to the side of the first encapsulation plate 131 near the notch 11. A first encapsulation groove 133 is formed between adjacent first encapsulation teeth 132. (Refer to...) Figure 2 and Figure 3 The insulating tube is made of elastic material. When the two first encapsulation strips 13 are manually pried apart, the notch 11 of the insulating tube is in an open state. At this time, the insulating tube 1 can be fitted onto the outer circumference of the conductor through the notch 11. After the two first encapsulation strips 13 are loosened, the two first encapsulation strips approach each other and mesh with each other through the first encapsulation teeth 132 and the first encapsulation groove 133, so that the notch 11 of the insulating tube is in a closed state, which plays an insulating role. The design of multiple first encapsulation teeth and first encapsulation grooves greatly increases the creepage distance of the insulating tube from the inside to the outside, further enhancing the insulation effect and improving construction safety.

[0029] To prevent deformation of the two first encapsulation strips from causing loosening of the meshing structure, in a further embodiment of this utility model, the insulating tube 1 further includes a support strip 14. The support strip 14 is disposed on the side of the first encapsulation strip 13 away from the insulating tube notch 11. The support strip 14 includes a support plate 141 connected to the outer wall of the insulating tube and a support tooth 142 connected to the side of the support plate near the first encapsulation plate 131. The ends of the support plate 141 and the support tooth 142 are in movable contact with the side of the first encapsulation plate 131 away from the insulating tube notch 11. Under the action of the support strip 14, the first encapsulation strip 13 is subjected to a supporting force in the direction of the insulating tube notch 11, making the meshing structure formed by the two first encapsulation strips tighter.

[0030] To address the issue of seams when multiple insulating tubes are connected, in a further embodiment of this invention, the conductor insulation shield also includes a connecting sleeve 2. Both ends of the connecting sleeve 2 form connecting ports 21 into which the ends of the insulating tube 1 can be inserted. The radial side of the connecting sleeve has a sleeve notch 22 similar in structure to the insulating tube notch 11. The connecting sleeve has two free ends located on either side of the sleeve notch 22. Each free end is connected to a second sealing strip 23. The second sealing strip includes a second sealing plate 231 connected to the outside of the connecting sleeve. Several second sealing teeth 232 are connected to the side of the second sealing plate closest to the sleeve notch, and a second sealing groove 233 is formed between adjacent second sealing teeth. Similar to the working principle of the first sealing strip, when the two second sealing strips are opened, the sleeve notch 22 is in an open state, allowing the conductor to enter the connecting sleeve. When the two second sealing strips approach each other and engage through the second sealing teeth and the second sealing groove, the sleeve notch is in a closed state. A partition 24 is provided in the middle of the connecting sleeve, with a through hole 241 in the middle of the partition.

[0031] Reference Figure 4 and Figure 5 After the end of the insulating tube 1 is inserted into the connecting sleeve 2 through the connecting port 21, the end of the insulating tube will abut against the partition 24. The through hole 241 in the middle of the partition is connected to the opening of the insulating tube, forming a wiring channel for the wire to pass through. By inserting the first insulating tube 1a and the second insulating tube 1b into the connecting sleeve 2 from both sides, the coverage length of the wire insulation shield can be extended to twice. Similarly, by setting more insulating tubes 1 and connecting sleeves 2, the complete coverage of the working area can be achieved. In some embodiments, the connection port 21 is provided with a limiting constriction 211 that protrudes radially inward. The limiting constriction can abut against the outer wall of the insulating tube to improve the connection stability between the insulating tube and the connecting sleeve. In other embodiments, a guide flare with an gradually increasing inner diameter can be provided on the outer side of the limiting constriction 211 in a direction away from the limiting constriction 211. The guide flare facilitates the insertion of the insulating tube. In addition, to improve the connection stability, a protruding limiting block 15 can be provided on the outer wall of the insulating tube 1. The limiting block is close to the end of the insulating tube and can prevent the insulating tube from detaching from the connecting sleeve.

[0032] In the specific construction process of this utility model, an insulating tube 1 and a connecting sleeve 2 can be inserted and welded together to form an integrated shielding unit. Subsequently, only the shielding units need to be connected one by one. Compared to directly installing the insulating tube and connecting sleeve onto the conductor, the formation of the shielding unit significantly reduces the workload. Furthermore, after the shielding unit is welded together, a protective outer shell 25 can be fitted around the connecting sleeve and welded to it, thereby improving the structural strength and insulation effect of the connecting sleeve.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
