Description

Technical Field

[0001] This utility model relates to the field of electrical equipment insulation construction technology, specifically to a flexible portable insulating curtain for live-line work. Background Technology

[0002] During the inspection, maintenance, or installation of electrical equipment, there is often a need to disconnect all electrical equipment from power for the inspection work. For other energized electrical equipment besides the target equipment, insulating materials are needed to isolate the live parts to ensure the safety of the workers. Traditional insulating materials, such as insulating boards, can provide necessary insulation protection, but they are often bulky, inconvenient to carry, and not flexible enough to be adjusted to adapt to complex and changing working environments.

[0003] The utility model patent CN209001450U discloses an insulating isolation baffle for live-line work, including an insulating plate, an adsorption device, and a connector. The adsorption device and the connector are located on both sides of the insulating plate. The connector passes through the insulating plate and connects to the adsorption device. After the adsorption device adsorbs the insulating plate, it fixes the insulating plate. Multiple insulating plates can be combined and expanded with the adsorption device and the connector. In this patent, the insulating plate isolates the live electrical equipment. However, during the isolation process, it can only block and isolate from one direction, limiting the isolation area. At the same time, the adsorption device relies on strong magnetic force to attract the columns or electrical beams on both sides of the distribution cabinet. The insulating plate comes into contact with the live electrical equipment, posing a safety hazard. The strong magnetic force makes it very difficult to remove the insulating plate, and it is also easy to attract the vehicle body or other objects during transportation, making it inconvenient to use.

Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example 1, see Figure 1 The present invention relates to a flexible portable insulating curtain for live-line work, comprising an insulating component and a supporting component.

[0022] The insulation assembly includes multiple sets of insulation plates 1 and a flexible insulation layer 2 connecting the multiple sets of insulation plates 1. The flexible insulation layer 2 has mounting cavities 3 spaced apart, and the insulation plates 1 are located in the mounting cavities 3. The support assembly includes multiple sets of support rods 4 respectively set on the multiple sets of insulation plates 1 and a bottom support member 5 detachably connected to the support rods 4. The multiple sets of support rods 4 are respectively provided with connectors 6 in the vertical direction. The connectors 6 move upward under the action of external force to connect adjacent support rods 4, thereby making the adjacent insulation plates 1 in a vertical state. The bottom support member 5 is detachably provided with an auxiliary support member 7. The auxiliary support member 7 unfolds under the action of external force to form a triangular stable support with the insulation plates 1 and the bottom support member.

[0023] Preferably, the insulation board 1 is made of FR-4 fiberglass board. The insulation board 1 is a rectangular board with a width ranging from 25cm to 35cm, a length ranging from 30cm to 50cm, and a thickness of 0.5cm.

[0024] Preferably, the flexible insulation layer 2 is made of polyurethane roll sheet with a thickness of 0.5cm.

[0025] Furthermore, the flexible insulating layer 2 is in the shape of a cross grid, and the grid of the flexible insulating layer 2 is hollow to form an installation cavity 3. A tightening layer 8 is provided on the inner wall of the installation cavity 3. The side wall of the insulating plate 1 abuts against the inner wall of the installation cavity 3, and the end face of the insulating plate 1 is connected to the tightening layer 8.

[0026] Preferably, the tightening layer 8 is also made of polyurethane roll, and the end face of the insulating board 1 is bonded to the tightening layer 8.

[0027] In the above configuration, the cross-shaped flexible insulating layer 2 forms multiple sets of mounting cavities 3. The tightening layer 8 is located on the front and rear end faces of the insulating plate 1. After the insulating plate 1 is placed in the mounting cavity 3, the tightening layer 8 on the front and rear sides of the insulating plate 1 is connected to the end face of the insulating plate 1 by adhesive bonding. This allows multiple sets of insulating plates 1 to be connected and folded at the flexible insulating layer 2. They are connected to each other in the vertical direction by the support rod 4, allowing the insulating plate 1 to be unfolded in the vertical direction for easy storage and unfolding. At the same time, the relative position between adjacent insulating plates 1 in the vertical direction can be adjusted to adjust the overall position to shield and isolate live electrical equipment. Storage and unfolding are convenient and quick, and disassembly is also convenient.

[0028] Furthermore, the connector 6 includes a connecting rod 601, on which a push handle 602 is provided; the upper end of the support rod 4 is provided with a sliding cavity 9, and the lower end of the support rod 4 is provided with an abutment cavity 10; the outer wall of the support rod 4 is provided with a sliding groove 11 that penetrates the sliding cavity 9, and a snap-fit ​​groove 12 is provided on the side of the sliding groove 11; the connecting rod 601 is slidably located in the sliding cavity 9, and the push handle 602 is located in the sliding groove 11.

[0029] Preferably, the support rod 4 is a cylindrical rod structure, and the two ends of the support rod 4 are hollow to form a sliding cavity 9 and an abutment cavity 10, respectively.

[0030] Preferably, two sets of "L"-shaped fixing rods 13 are provided on the outer walls of both ends of the support rod 4. The short side of the fixing rod 13 is fixedly connected to the support rod 4, and the long side is set opposite to it.

[0031] In the above configuration, the insulating plate 1 is installed in the space between the two sets of "L"-shaped fixing rods 13 and the support rods 4. The insulating plate 1 and the support rods 4 are fixedly connected by the "L"-shaped fixing rods 13. When the adjacent support plates are unfolded in the vertical direction, the connecting rod 601 located below is pushed upward from bottom to top by the push handle 602 and moved into the abutment cavity 10 of the upper support rod 4. The push handle 602 is rotated to enter the snap-fit ​​groove 12, so that the adjacent insulating plates 1 are unfolded and connected and fixed in the vertical direction.

[0032] Furthermore, the bottom support 5 includes a bottom connecting frame 501 and two sets of bottom support plates 502 that are rotatably and symmetrically arranged on the bottom connecting frame 501. The bottom plate connecting frame is provided with a plug groove 14, and one set of insulating plates 1 is fixed in the plug groove 14. The auxiliary support 7 includes an auxiliary support rod 701, which is movably connected to the bottom support plate 502. The insulating plate 1 is provided with a fixing block 15 that is connected to the end of the auxiliary support rod 701 away from the bottom support plate 502.

[0033] Preferably, the bottom connecting frame 501 is a hollow rectangle with one end open, and the hollow interior of the bottom connecting frame 501 forms an insertion groove 14.

[0034] Preferably, the bottom support plate 502 is U-shaped, with rotating holes 16 at both ends, and a rotating shaft 17 at the bottom end of the bottom connecting frame 501. The bottom support plate 502 is rotatably connected to the rotating shaft 17 through the rotating holes 16.

[0035] Preferably, the fixing block 15 is provided with fixing holes 18, which are inclined; the bottom support plate 502 is provided with an abutment plate 19 at one end away from the bottom support frame, and the abutment plate 19 is provided with an abutment hole. One end of the auxiliary support rod 701 is connected to the abutment hole, and the other end is inserted into the fixing hole 18 on the fixing block 15.

[0036] In the above configuration, the auxiliary support rod 701 can be pulled out from the fixing hole 18, flipped over and attached to the bottom support plate 502, and then the bottom plate support rod 4 is flipped over and attached to the insulating plate 1, so that the bottom support plate 502 and the auxiliary support rod 701 can be folded together to reduce the space occupied. In the process of unfolding the insulating plate 1 to form an insulating protective layer to isolate live electrical equipment, the bottom support plate 502 is first flipped to be perpendicular to the insulating plate 1, and then the auxiliary support rod 701 is flipped to be tilted to the bottom support plate 502 and inserted into the fixing hole 18. At this time, a stable triangular support is formed between the auxiliary support rod 701, the bottom support plate 502 and the insulating plate 1, and the bottom support plate 502 and the auxiliary support rod 701 are provided on both sides of the insulating plate 1 to provide stable support for the insulating plate 1.

[0037] In this embodiment, multiple sets of insulating plates 1 connected by flexible insulating layers 2 can be folded to each other, reducing the space occupied, facilitating transportation, and making them easy to carry. Stable support is provided by unfolding the bottom support plate 502 and auxiliary support rods 701. Multiple sets of support rods 4 in the vertical direction are connected and fixed by connecting rods 601 and push handles 602 on the support rods 4, so that multiple insulating plates 1 in the vertical direction are fixed to form an insulating curtain, which can shield the periphery of live electrical equipment. By adjusting the position between adjacent insulating plates 1 in the vertical direction, the insulating plates 1 originally on the same surface can be adjusted to form a polygonal structure, which can wrap around the live electrical equipment. The shape of the insulating curtain can be adjusted to shield the live electrical equipment and form isolation.

[0038] In embodiment 2, the insulating plates 1 on both sides of the insulating curtain are respectively provided with a first connecting part 20 and a second connecting part 21. The first connecting part 20 and the second connecting part 21 are connected to each other so that multiple sets of insulating curtains can be connected to each other.

[0039] Preferably, the first connecting part 20 is a first connecting nut 22 disposed on the insulating plate 1, and the second connecting part 21 includes a second connecting nut 23 disposed on the insulating plate 1 and a connecting stud 24 disposed inside the second connecting nut 23.

[0040] In the above configuration, the same insulating curtain or different insulating curtains can be connected to the first connecting nut 22 by rotating the connecting stud 24 to form a closed polygonal structure, thereby completely surrounding the entire live electrical equipment and providing more comprehensive isolation. At the same time, the insulating curtain is divided into multiple groups, which is convenient for disassembly, carrying and assembly.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
