Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a wire shielding tube with a hanging function. Background Art

[0002] The safety precautions for live wires stipulate that the minimum safe distance between operators and live wires should be no less than 0.4 meters, and no less than 0.6 meters from adjacent phases. If the distance is not enough, insulation shielding should be done. For live wire disconnection and connection operations on 10kV distribution networks without power outages, operators should be 2m away from live wires. Use an insulating operating rod to insulate and shield the locations that are easily connected to the grounding body and may short-circuit during the operation. The insulation shielding tools are mainly shielding (tube) covers. For large-span live wire disconnection and connection operations, there are no shielding tools for the leads, and live wire operations cannot be performed. For insulated boom truck operations, leads of 2m or more in length cannot be fixed at all, and two or more ordinary The wire shielding tube of the general type is used for shielding. The lead wire has no fixed fulcrum and the operator cannot tighten it. Therefore, it is necessary to design a wire shielding tube with a lifting function. After searching the publication number (CN205377165U), a wire shielding tube with a lifting function is disclosed. The two ends of the wire shielding tube are smooth parts, the middle is a corrugated part, and there is an opening along the length direction. The center line of the length direction of the wire shielding tube is taken as the center. Two pull ring bodies are provided at the outer end of the corrugated part symmetrical to the opening, and two hanging ring bodies are provided at the outer end of the corrugated part in a direction perpendicular to the center line of the length direction of the wire shielding tube. The pull ring body has the same structure as the hanging ring body, and the two hanging ring bodies are provided with insulating hooks.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: the corrugated part in the above-mentioned existing patent is used to place the wire, and the hook is fixed on the outside of the corrugated part. Due to the problem of weak supporting capacity of the material of the corrugated part, when the wire is located inside the corrugated part and is in a hanging state, the wire is very easy to fall off from the notch of the corrugated part, and there is a problem of poor stability when the wire is hung, which needs to be improved. Therefore, we propose a wire shielding tube with a hanging function. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1, as Figure 1-3 As shown, the utility model provides a technical solution: a wire shielding tube with a hanging function, comprising an insulating sleeve 1, a fixed ring 2, a movable ring 3 and a hanging ring 4, the insulating sleeve 1 is provided with a notch 101 for accommodating the entry of the wire, the fixed ring 2 is provided with an opening 206 consistent with the notch 101, the surface of the fixed ring 2 is provided with three hanging holes 203 of the same size, the three hanging holes 203 are respectively hung with a hanging ring 1 204, a hanging ring 205, and a hanging ring 3 207, the hanging ring 205 and the hanging ring 3 207 are respectively arranged at the upper and lower ends of the opening 206, the fixed ring 2 is clamped on the outside of the insulating sleeve 1, the opening 206 of the fixed ring 2 is horizontally aligned with the notch 101 of the insulating sleeve 1, the hanging ring 4 is fixedly connected to the movable ring 3, and the movable ring 3 is connected to the fixed ring 2.

[0020] In a specific embodiment of the present invention, after the insulating sleeve 1 and the fixing ring 2 are installed, the fixing ring 2 and the insulating sleeve 1 are fastened by bonding and the opening 206 of the fixing ring 2 is horizontally aligned with the notch 101 of the insulating sleeve 1. The material of the fixing ring 2 is glass fiber reinforced plastic (FRP), which has excellent strength, rigidity and insulation. The three hanging rings are made of aluminum alloy with high strength and toughness. The movable ring 3 is provided with a buckle that can be elastically opened (such as Figure 1 As shown), pressing the buckle makes the buckle rotate, and the movable ring 3 opens a notch for passing the ring, and the hanging ring is hung with any surrounding object that can be hung.

[0021] In the preferred technical solution, when the notch 101 of the insulating sleeve 1 is aligned with the horizontal line, the movable ring 3 is connected to the hanging ring 1 204, and when the notch 101 of the insulating sleeve 1 is vertically upward, the movable ring 3 is connected to the hanging ring 205 and the hanging ring 3 207. This switching method not only facilitates the entry of the wire into the insulating sleeve 1, but also ensures the stability of the lifting process after the wire enters the insulating sleeve 1.

The weight-reducing holes are provided to reduce the overall mass of the fixing ring 2, and the frame structure is conducive to uniform force.

[0023] In the preferred technical solution, the thickness of the fixing ring 2 is set to 50 mm. A thicker fixing ring 2 is beneficial for improving the supporting performance.

[0024] Working principle: When the wire is not inserted into the insulating sleeve 1, the movable ring 3 cooperates with the hanging ring 204 and the notch 101 is in a horizontal state, so that the wire is smoothly embedded in the insulating sleeve 1, and then the movable ring 3 is separated from the hanging ring 204, so that the movable ring 3 cooperates with the hanging ring 205 and the hanging ring 3 207 at the same time. At this time, the notch 101 of the insulating sleeve 1 is facing upward, and the hanging ring 4 is hung with a nearby hanging object. There is no need to worry about the wire falling off from the notch 101 of the insulating sleeve 1 during the hanging process.
