Description

Technical Field

[0001] The utility model relates to the field of overhead lines, in particular to a clamp for reducing the bottle-falling rate of overhead conductors of distribution lines. Background Art

[0002] In overhead lines, the connection between conductors and insulators is an important link to ensure the safe operation of the line. If the connection is poor or aging, it may cause the connection between the conductors and insulators to loosen or fall off, thus affecting the electrical performance and mechanical strength of the line. Therefore, the bottle-off rate is an important indicator reflecting the line operation status and equipment quality.

[0003] The overhead wires of distribution lines are an important part of the power system, and their stable operation is directly related to the safety and reliability of the power system. However, the phenomenon of overhead wire debonding brings great safety hazards to the stable operation of the power system. Once the insulators are loosened from the fixed wires, the wires will float in the air, which may easily cause line short circuits, power outages and other accidents, and even cause casualties and property losses in severe cases.

[0004] At present, insulators and conductors are usually fixed by bundling them with lines, such as wires. There is a problem that insulators of overhead conductors may become loose from the conductors due to factors such as breeze vibration, and further improvements are needed.

[0005] Therefore, it is necessary to invent a fixture that reduces the bottle-off rate of overhead wires in distribution lines. Utility Model Content

[0010] Preferably, the protection component comprises two arc-shaped rubber pads, and the surfaces of the two arc-shaped rubber pads are respectively bonded to the inner surfaces of two arc-shaped clamps.

[0011] Preferably, the second fixing assembly includes two connecting plates, which are respectively fixed to the middle of the outer surfaces of the two arc-shaped clamps, second threaded holes are provided at both ends of the connecting plates, and a clamping protrusion for clamping the wire is provided in the middle of the connecting plates.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Please refer to the attached Figure 1-5 The utility model provides a clamp for reducing the de-bottle rate of overhead wires in distribution lines, comprising two symmetrically arranged arc clamps 1, an insulator 2 and a required overhead wire 3. The insulator 2 and the wire 3 are both well-known technologies to those skilled in the art, and will not be described in detail. The wire 3 is preferably set as a 10KV distribution line overhead wire. The two arc clamps 1 are detachably mounted on the surface of the insulator 2 through a first fixing component, and the wire 3 is detachably connected to the two arc clamps 1 through a second fixing component, that is, the clamp can have the function of convenient disassembly and assembly, and the inner surfaces of the two arc clamps 1 are provided with protective components;

[0023] The first fixing assembly includes four end plates 4, which are respectively arranged at the opposite ends of the two arc-shaped clamps 1. The end plates 4 and the arc-shaped clamps 1 are an integrated structure. A first threaded hole 5 is opened in the center of each end plate 4. The hole wall of the first threaded hole 5 is threadedly connected with a first fixing bolt 6, that is, under the action of the first fixing bolt 6, the end plates 4 can be fixedly connected, so that the opposite ends of the two arc-shaped clamps 1 are fixedly connected, so that the two arc-shaped clamps 1 can be detachably installed on the insulator 2. The first fixing assembly also includes a first anti-loosening gasket 7, which is sleeved on the surface of the first fixing bolt 6, that is, under the action of the first anti-loosening gasket 7, the stability of the first fixing bolt 6 when fixedly connecting the end plates 4 can be effectively improved;

[0024] The protection component includes two arc-shaped rubber pads 8, and the surfaces of the two arc-shaped rubber pads 8 are respectively bonded to the inner surfaces of the two arc-shaped clamps 1. Therefore, under the action of the two arc-shaped rubber pads 8, not only can the surface of the insulator 2 be protected, that is, the arc-shaped clamp 1 is prevented from clamping the insulator 2, but also the friction between the insulator 2 and the arc-shaped clamp 1 can be effectively increased, and the arc-shaped rubber pads 8 can also play a certain buffering role;

[0025] The second fixing assembly includes two connecting plates 9, which are respectively fixed to the middle of the outer surfaces of the two arc-shaped clamps 1, and the connecting plates 9 and the arc-shaped clamps 1 are an integral structure. Second threaded holes 10 are provided at both ends of the connecting plates 9, and a clamping protrusion 11 for clamping the wire 3 is provided in the middle of the connecting plates 9. The clamping protrusion 11 and the connecting plates 9 are an integral structure. The second fixing assembly also includes two arc-shaped pressing sheets 12, and the two arc-shaped pressing sheets 12 correspond to the two connecting plates 9 one by one. It should be noted that the middle part of the arc-shaped pressing sheet 12 is arc-shaped (such as Figure 3-4 As shown), in conjunction with the use of the positioning protrusion 11, it can be used to limit the position of the wire 3 to prevent the wire 3 from being offset. A third threaded hole 13 is opened at both ends of the arc-shaped pressing piece 12, and the second threaded hole 10 corresponds to the third threaded hole 13 one by one. The hole wall of the second threaded hole 10 and the corresponding hole wall of the third threaded hole 13 are both threadedly connected with a second fixing bolt 14, so under the action of the second fixing bolt 14, the arc-shaped pressing piece 12 can be fixedly connected to the connecting plate 9, so that the arc-shaped pressing piece 12 clamps the wire 3 in the positioning protrusion 11 in the middle of the connecting plate 9, and it is also convenient for disassembly and assembly, that is, the clamp can effectively clamp the required overhead wire on the insulator, thereby effectively reducing the probability of the overhead wire insulator loosening from the wire due to factors such as vibration;

[0026] The second fixing bolts 14 are sleeved with second anti-loosening washers 15 on their surfaces, that is, under the action of the second anti-loosening washers 15 , the stability of the second fixing bolts 14 when fixedly connected to the connecting plate 9 can be effectively improved.

[0027] The use process of the utility model is as follows: a technician in this field first aligns and places the two arc clamps 1 on the surface of the insulator 2, and then threadably connects the first fixing bolt 5 with the first threaded hole 6 on the end plate 4, so that the two arc clamps 1 can be clamped and fixed on the insulator 2, and then the required overhead wire 3 is placed in the clamping protrusion 11 in the middle of the two connecting plates 9, and the second threaded hole 10 and the third threaded hole 13 are threadably connected by the second fixing bolt 14, and the arc pressing piece 12 is fixedly connected to the connecting plate 9, so that the wire 3 placed in the clamping protrusion 11 is clamped and fixed. Similarly, the reverse operation can disassemble the wire 3 and the arc clamp 1, that is, the clamp can effectively clamp the required overhead wire on the insulator, thereby effectively reducing the probability of the overhead wire insulator loosening from the wire due to factors such as vibration, and it is convenient to disassemble and assemble, and has good flexibility.

[0028] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
