Description

[0002] At present, when a distribution live operation project is carried out by using a full insulation operation method, the conductors in the operation range need to be shielded by using an insulation shielding tool to ensure the safety of the operation. However, in the actual operation scene, the problems of low shielding efficiency and difficult simultaneous guarantee of operation safety are particularly prominent: on the one hand, the single length of the traditional insulation shielding tool is fixed (≥1.5 meters), and in the actual installation, the operation personnel reach the first operation position, complete the installation of the insulation shielding tool of one operation point, and then move to the adjacent other operation position to install the second insulation shielding tool.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0021] Reference will now be made to Figures 1-2 The stretchable and adaptive insulation shielding cover 100 according to one embodiment includes an insulation shielding outer cover 10 and an insulation shielding inner cover 20. In use, the insulation shielding outer cover 10 and the insulation shielding inner cover 20 are both used to be sleeved to the outer circumferential portion of a conductor wire, so as to isolate the live or possibly live conductor wire from the operator, and avoid the operator from being too close to the conductor wire or accidentally touching the conductor wire, and thus causing a safety accident of electric shock.​

[0022] For example, the insulating material used for the insulating shielding outer cover 10 and the insulating shielding inner cover 20 can be glue, resin, etc.

[0023] Please refer to Figure 3 and Figure 4 In the present scheme, the inside of the insulating shielding outer cover 10 is formed with a receiving cavity 11, and one end of the insulating shielding outer cover 10 is provided with an inlet and outlet 12 which communicates with the receiving cavity 11; one end of the insulating shielding inner cover 20 is slidably arranged in the receiving cavity 11 through the inlet and outlet 12, so that the insulating shielding inner cover 20 and the insulating shielding outer cover 10 can be adjusted in extension and contraction, and the other end of the insulating shielding inner cover 20 is provided as an operating end 21 which extends to the outside of the inlet and outlet 12.

[0024] It can be understood that the telescopic sleeve structure design of the insulating shielding outer cover 10 and the insulating shielding inner cover 20 has the advantages that, on the one hand, when not in use, the two are contracted and matched, the structure is compact, which not only saves installation space and packaging materials, but also makes it more convenient for workers to carry and transport; on the other hand, the insulating shielding outer cover 10 and the insulating shielding inner cover 20 shell are adjusted in stepless extension and contraction, so that the insulating shielding device 100 can flexibly obtain different lengths to meet the needs of different use scenarios, and the versatility of the insulating shielding device 100 is improved.

[0025] The implementation of the embodiment of the present application has the following beneficial effects: the insulating shielding device 100 of the present scheme is particularly applied in the occasion of power distribution live working, and is used for shielding the wires in the working range when in use to achieve protection of the workers; specifically, in the initial state, the insulating shielding inner cover 20 is contracted and accommodated in the inside of the insulating shielding outer cover 10, at this time, the volume of the insulating shielding device 100 is small, the structure is compact, and it is convenient for workers to carry and perform installation operation; when in use, first, the insulating shielding inner cover 20 is installed to the outside of the wire segment in the first working position area, and after the working content of the wire segment is completed, the insulating shielding outer cover 10 can be directly pulled out, so that the insulating shielding outer cover 10 is extended relative to the insulating shielding inner cover 20, so that the insulating shielding outer cover 10 can shield another wire segment in the second working position area adjacent to the first working position area, thus, it is convenient for workers to perform the operation of the working content; then, the insulating shielding inner cover 20 is pushed into the receiving cavity 11 of the insulating shielding outer cover 10, and the insulating shielding outer cover 10 is pulled, so that the insulating shielding device 100 can continuously peristaltic on the wires, and the effect of continuously shielding and protecting different parts of the wires is achieved. Compared with the prior art, the continuous shielding mechanism design of the telescopic sliding of the insulating shielding device 100 not only saves the use of a boom truck, reduces the installation difficulty, improves the working efficiency, but also eliminates the problem of electric shock safety hazard caused by the lack of shielding and protection of the wire segment, greatly improves the safety and reliability of the power distribution live working.

[0026] Please refer to Figures 5 to 7 In one embodiment, the outer peripheral wall of the insulation shielding inner cover 20 protrudes at one end away from the operating end 21 to form a first annular protrusion 22, which is in slidable abutment with the side wall of the accommodation cavity 11, so that the outer peripheral wall of the insulation shielding inner cover 20 is in clearance fit with the side wall of the accommodation cavity 11.

[0027] By virtue of the abutment of the first annular protrusion 22 with the side wall of the accommodation cavity 11, a guiding and limiting effect is achieved when the insulation shielding outer cover 10 and the insulation shielding inner cover 20 are relatively extended and retracted, while the outer peripheral wall of the insulation shielding inner cover 20 is in clearance fit with the side wall of the accommodation cavity 11, greatly reducing the contact area between the insulation shielding inner cover 20 and the insulation shielding outer cover 10, and further greatly reducing the frictional resistance of the relative sliding, improving the smoothness and convenience of the extension and retraction, and reducing the work burden of the operator.

[0028] Further, in one embodiment, the inner peripheral wall of the insulation shielding outer cover 10 protrudes near the inlet and outlet 12 to form a second annular protrusion 13. When the insulation shielding outer cover 10 and the insulation shielding inner cover 20 are relatively extended to the limit position, the first annular protrusion 22 and the second annular protrusion 13 abut each other. When the insulation shielding outer cover 10 and the insulation shielding inner cover 20 are extended to the limit position, i.e., the insulation shielding device 100 is at the maximum extension length, the first annular protrusion 22 automatically abuts the second annular protrusion 13, forming a mechanical limiting and locking, preventing the insulation shielding inner cover 20 from falling off the insulation shielding outer cover 10.

[0029] Please refer to Figure 1 and Figure 2 In one embodiment, the other end of the insulation shielding outer cover 10 is also provided with a first opening 14 which is in communication with the accommodation cavity 11, and the first opening 14 and the inlet and outlet 12 are respectively located at the axially opposite ends of the insulation shielding outer cover 10.

[0030] The side wall of the insulation shielding outer cover 10 is also provided with a first strip-shaped hole 15, which is arranged in a penetrating structure from the inlet and outlet 12 to the first opening 14.

[0031] With the above structure design, the insulation shielding outer cover 10 is equivalent to a circumferentially semi-closed circular structure, at this time the insulation shielding outer cover 10 has a certain expansion and contraction deformation capability, so as to flexibly change the size of the accommodation cavity 11, and further meet the installation needs of different diameter wires, and improve the applicability of the insulation shielding outer cover 10.

[0032] Please refer to Figure 2 and Figure 4Further, in the above embodiment, the first strip-shaped hole 15 has opposite first and second hole walls, the first hole wall is provided with a first extension plate 16 outward protruding towards the outside of the insulation shielding cover 10, the second hole wall is provided with a second extension plate 17 outward protruding towards the outside of the insulation shielding cover 10, and the first and second extension plates 16 and 17 are arranged side by side. The outward protruding first and second extension plates 16 and 17 are arranged side by side, have a larger fitting area compared with the first and second hole walls, extend the diameter of the first strip-shaped hole 15, can form a better locking effect on the wire, prevent the wire from being accidentally pulled out of the first strip-shaped hole 15, and improve the reliability of the assembly of the insulation shielding cover 10 and the wire.

[0033] Similarly, in one embodiment, the insulation shielding inner cover 20 is provided with a second opening 23 and a third opening 24 at opposite axial ends, respectively, and a wire accommodating cavity is formed in the inside of the insulation shielding inner cover 20 for accommodating the wire. Thus, the wire accommodating cavity is equivalent to a cavity structure penetrating through both ends, so as to meet the installation requirement of the wire passing through the inside of the insulation shielding inner cover 20, so as to realize the shielding of the wire by the insulation shielding inner cover 20, and further provide protection for the operator.

[0034] Further, in one embodiment, the sidewall of the insulation shielding inner cover 20 is further provided with a second strip-shaped hole 25 arranged in a penetrating structure from the second opening 23 to the third opening 24.

[0035] With the above structure, the insulation shielding inner cover 20 is equivalent to a circumferentially semi-closed circular structure, and at this time, the insulation shielding inner cover 20 has a certain expansion and contraction deformation capability, so as to flexibly change the size of the accommodation cavity 11, and further meet the installation requirement of the wire with different diameters, and improve the applicability of the insulation shielding inner cover 20.

[0036] It should be noted that the size of the insulation shielding inner cover 20 and the size of the insulation shielding outer cover 10 can be selected according to the size of the wire, so as to meet the installation requirement of the wire by the insulation shielding inner cover 20 and the insulation shielding outer cover 10, and at the same time, ensure the normal assembly of the insulation shielding inner cover 20 and the insulation shielding outer cover 10.

[0037] In one embodiment, the second strip-shaped through hole has opposite third and fourth hole walls, the third hole wall is provided with a third extension plate 26 outward protruding towards the outside of the insulation shielding inner cover 20, the fourth hole wall is provided with a fourth extension plate 27 outward protruding towards the outside of the insulation shielding inner cover 20, the third and fourth extension plates 26 and 27 are arranged side by side, and are slidably arranged in the guide groove spaced by the first and second extension plates 16 and 17.

[0038] On one hand, the third extension plate 26 and the fourth extension plate 27 are arranged side by side and protrude outward, and have a larger fitting area compared with the third hole wall and the fourth hole wall, thereby extending the diameter of the second slot 25, forming a better locking effect on the wire, preventing the wire from accidentally coming out of the second slot 25, and improving the reliability of the assembly of the inner shield 20 and the wire; on the other hand, the third extension plate 26 and the fourth extension plate 27 form a guide rail structure, which is then slid in the guide groove formed by the first extension plate 16 and the second extension plate 17, thereby playing a good wire guiding and limiting role when the inner shield 20 and the outer shield 10 relatively stretch and contract, and improving the stability of the stretching and contraction of the two.

[0039] Please refer to Figure 1 and Figure 3 In addition, in one embodiment, the outer wall of the operation end 21 is formed with a first stepped structure 211 and a second stepped structure 212, and the first stepped structure 211 and the second stepped structure 212 are arranged in sequence along the axial direction of the inner shield 20.

[0040] Specifically, the first stepped structure 211 is arranged closer to the outer shield 10 than the second stepped structure 212, and when the outer shield 10 and the inner shield 20 are contracted to the limit position, the first stepped structure 211 abuts against the end wall of the outer shield 10 for enclosing the inlet and outlet 12, thereby achieving contraction positioning.

[0041] The second stepped structure 212 has a ring-shaped protruding structure, so it is convenient to be installed and matched with the hands of the operator or tools such as pull rods, tongs, etc., thereby facilitating the operator to drive the inner shield 20.

[0042] In one embodiment, the inner shield 20 is made of soft material, and the outer shield 10 is made of soft material; or the inner shield 20 is made of soft material, and the outer shield 10 is made of hard material; or the inner shield 20 is made of hard material, and the outer shield 10 is made of hard material; or the inner shield 20 is made of hard material, and the outer shield 10 is made of soft material.

[0043] Considering that the wire may not be completely flat in actual operation scenarios, and the line direction has a certain curvature, the outer shield 10 and the inner shield 20 are respectively made of different types of insulating materials, and this design enables the insulation shielding device 100 to shield the wire with a curved arc within a certain range, thereby greatly enhancing its versatility under different working conditions.

[0044] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
