Description

Technical Field

[0001] The invention relates to the technical field of high-voltage power grids, and in particular to a split conductor anti-falling grounding wire device. Background Art

[0002] During the maintenance and overhaul of the power system, in order to ensure the safety of the staff, the equipment or lines in the high-voltage power grid will be connected to the ground to form a low-impedance path, reduce the fault current and voltage, and prevent electric shock accidents. The existing high-voltage grounding wire generally uses a U-shaped hook-type grounding hook body to directly hang on the copper busbar of the wire or cable, and then the grounding hook body is connected to the grounding wire to complete the grounding operation of the wire.

[0003] Generally, a single grounding device can only connect one wire and has no locking function. If there is a strong wind, it may be blown and shaken, and then fall out of the wire, and the wire cannot be grounded. The falling off of the grounding wire can easily lead to safety accidents of electrical equipment. The fault tolerance rate is low, which is an extremely serious safety hazard for the staff. Moreover, the power supply lines are generally split into multiple wires or branches arranged up and down. Therefore, when the staff performs maintenance, multiple wires or branches need to be grounded, but the grounding device can only connect one wire, so grounding a single wire is an extremely tedious task and takes a lot of time. Therefore, there is an urgent need for a split wire anti-falling grounding wire device to solve the above problems. Summary of the invention

[0004] The main purpose of the present invention is to provide a split conductor anti-falling grounding wire device. After the two grounding structures are connected to the two conductors, the distance between the two conductors can be shortened. After the two conductors are shortened, a reaction force will be applied to the grounding structure due to deviation from a predetermined layout path, thereby improving the connection stability between the grounding structure and the conductor, preventing the grounding structure from falling from the conductor, and connecting the two conductors at one time to improve the grounding efficiency of the conductor.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A split conductor anti-falling grounding wire device comprises a grounding wire and two groups of insulating rods, both groups of insulating rods are fixed with grounding structures connected to the conductors, the grounding wire is connected to the two grounding structures, the two groups of insulating rods are connected by an elastic telescopic device, and the elastic telescopic device is used to shorten the distance between the two groups of conductors after the two groups of grounding structures are connected to the conductors.

[0006] Furthermore, the elastic telescopic device comprises a telescopic rod and an elastic member, the elastic member is sleeved on the periphery of the telescopic rod, and both ends of the telescopic rod and the elastic member are respectively fixed in the cavities of the two groups of insulating rods.

[0007] Furthermore, the telescopic rod comprises a sleeve and a sleeve rod, the sleeve rod is sleeved in the sleeve, and ends of the sleeve and the sleeve rod that are far away are respectively fixed in the cavities of the two groups of insulating rods through fixing seats.

[0008] Furthermore, the elastic member is a cylindrical spring, and the elastic member is located between two groups of fixing seats.

[0009] Furthermore, the two groups of insulating rods are respectively threadedly connected with fixing screws for fixing the elastic member.

[0010] Furthermore, the grounding structure is a U-shaped structure, wherein an elastic pressing piece is fixed to one inner side of a group of the grounding structures, and a terminal end of the elastic pressing piece is in contact with the other inner side wall of the grounding structure.

[0011] Furthermore, a guide plate is installed at the end of the U-shaped opening of another group of the grounding structures by bolts.

[0012] Furthermore, the grounding wire has three connection ends, two of which are connected to two groups of grounding structures through grounding pressure heads respectively.

[0013] Furthermore, an insulating rope is fixed on the grounding structure having the elastic pressing piece.

[0014] Furthermore, a slot is provided on the grounding structure having the elastic pressing sheet, and one end of the elastic pressing sheet is located in the slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects: After the two grounding structures of the present invention are connected to the two wires, the distance between the two wires can be shortened. After the two wires are shortened, a reaction force will be applied to the grounding structure due to deviation from the predetermined layout path, thereby improving the connection stability between the grounding structure and the wires and preventing the grounding structure from falling from the wires. In addition, the device connects two wires at one time, thereby improving the grounding efficiency of the wires.

[0016] The elastic member of the present invention will not bend significantly under the constraint of the telescopic rod, thereby ensuring that the movement paths of the two grounding structures are approximately located on the same straight line.

[0017] One end of the elastic pressing piece of the present invention is located in the slot, so that the wire cannot pass through the elastic pressing piece and enter the closed space formed by the elastic pressing piece and the grounding structure, which is convenient for personnel to separate the grounding structure and the wire later.

[0018] The two grounding structures of the present invention are connected by an elastic telescopic device, and the elastic force of the elastic telescopic device itself is used to lock the wire and prevent it from falling off. One of the grounding structures is combined with an elastic pressing sheet structure to further lock the wire, thereby playing a double protection role and effectively ensuring that the grounding structure will not fall off the wire due to shaking.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figure 1-4 As shown, a split conductor anti-falling grounding wire device includes a grounding wire 8 and two groups of insulating rods 2, both groups of insulating rods 2 are fixed with grounding structures 3 connected with conductors 13, the grounding wire 8 is connected to the two grounding structures 3, and the two groups of insulating rods 2 are connected by an elastic telescopic device, which is used to shorten the distance between the two groups of conductors 13 after the two groups of grounding structures 3 are connected to the conductors 13.

[0027] In this embodiment, if Figure 1 As shown, the grounding structure 3 is a U-shaped structure. When grounding two conductors 13, one of the grounding structures 3 can be hooked on the conductor 13 first, and then the other grounding structure 3 can be stretched by the elastic expansion device. Figure 5As shown, the distance between the two grounding structures 3 is increased, so that the other grounding structure 3 can hook the other wire 13. At this time, no external force is applied to the grounding structure 3, so that the two grounding structures 3 are reset under the action of the elastic expansion device, thereby shortening the distance between the two wires 13. After the two wires 13 are shortened, a reaction force is applied to the grounding structure 3 due to deviation from the predetermined layout path, thereby improving the connection stability between the grounding structure 3 and the wire 13, preventing the grounding structure 3 from falling off the wire 13, and connecting the two wires 13 at one time, thereby improving the grounding efficiency of the wire 13.

[0028] Among them, Figure 2 As shown, the elastic telescopic device includes a telescopic rod 1 and an elastic member 9. The elastic member 9 is sleeved on the outer periphery of the telescopic rod 1. The two ends of the telescopic rod 1 and the elastic member 9 are respectively fixed in the cavities 201 of the two groups of insulating rods 2. The telescopic rod 1 includes a sleeve 101 and a sleeve rod 102. The sleeve rod 102 is sleeved in the sleeve 101, so the sleeve rod 102 can be inserted into the sleeve 101. The ends of the sleeve 101 and the sleeve rod 102 that are far away from each other are respectively fixed in the cavities 201 of the two groups of insulating rods 2 through a fixing seat 103. When the distance between the two groups of insulating rods 2 changes, the distance of the sleeve rod 102 inserted into the sleeve 101 will change, so the distance between the two groups of grounding structures 3 can be adjusted, so that after the distance increases, the two groups of grounding structures 3 can respectively hook the two upper and lower arranged wires 13, and after the distance between the two groups of grounding structures 3 is shortened, the two wires 13 can be pulled closer, so that the force applied by the wires 13 to the grounding structure 3 is utilized to improve the connection stability between the grounding structure 3 and the wires 13.

[0029] like Figure 2 As shown, the elastic member 9 is a cylindrical spring. The elastic member 9 is located between the two groups of fixing seats 103 and contacts the fixing seats 103. The two groups of insulating rods 2 are respectively threaded with fixing screws 10 for fixing the elastic member 9. When the distance between the two groups of grounding structures 3 increases, the distance between the two groups of insulating rods 2 will also increase. Since the two ends of the elastic member 9 are respectively connected and fixed to the two groups of insulating rods 2, the elastic member 9 will be stretched. When the grounding structure 3 is not stretched by external force, the elastic member 9 will be reset, thereby shortening the distance between the two groups of insulating rods 2, and then shortening the distance between the two groups of grounding structures 3.

[0030] Among them, Figure 3As shown, an elastic pressing piece 6 is fixed to one side of the inner side of one group of grounding structures 3. The elastic pressing piece 6 is made of spring steel and has good elasticity. The end of the elastic pressing piece 6 contacts the other side wall of the grounding structure 3 to form a limiting angle. When the grounding structure 3 is connected to the wire 13, the wire 13 will enter the limiting angle, thereby contacting the elastic pressing piece 6 and the inner wall of the grounding structure 3, so that the elastic pressing piece 6 and the inner wall of the grounding structure 3 limit the wire 13, further improving the connection stability between the wire 13 and the grounding structure 3. A slot 301 is provided on the grounding structure 3 with the elastic pressing piece 6, and one end of the elastic pressing piece 6 is located in the slot 301, so that the wire 13 cannot pass over the elastic pressing piece 6 and enter the enclosed space formed by the elastic pressing piece 6 and the grounding structure 3, which is convenient for personnel to separate the grounding structure 3 and the wire 13 later.

[0031] An insulating rope 7 is fixed on the grounding structure 3 having the elastic pressing piece 6 , and a person can use the insulating rope 7 to operate the two sets of grounding structures 3 .

[0032] The U-shaped opening end of another set of grounding structures 3 is installed with a guide plate 5 through a bolt 11. The guide plate 5 enlarges the U-shaped opening angle of the grounding structure 3, so that the wire 13 can enter the U-shaped structure more easily.

[0033] Among them, the grounding wire 8 has three connection ends, two of which are connected to two groups of grounding structures 3 through grounding pressure heads 12 respectively. The grounding structure 3 is a U-shaped structure (the U-shaped structure, the grounding pressure head 12 and the grounding wire 8 are existing technologies and will not be described in detail here), which can hook the wire 13, and the remaining connection end of the grounding wire 8 can be connected to the ground wire, thereby completing the grounding operation of the wire 13.

[0034] Working principle: before use, the grounding pressure heads 12 at both ends of the device of the present invention are connected to the grounding wire 8 in advance, and then the staff holds the insulating rope 7 and throws the rest outward. Because the U-shaped hook body without the elastic pressing piece 6 is equipped with a guide plate 5, the angle of the U-shaped hook body is expanded, and because of the weight of the guide plate 5 itself, the U-shaped hook body will be opened downward by gravity, which improves the success rate of the U-shaped hook body at this end to hang the wire 13 when pulling the insulating rope 7; after the wire 13 is hung at this end with the guide plate 5, the staff Tighten the insulating rope 7, and under the action of the elastic member 9, the two insulating rods 2 are slowly separated. The elastic member 9 will not bend significantly under the constraint of the telescopic rod 1, which is convenient for the staff to better control the direction. The staff pulls the insulating rope 7, moves the U-shaped hook body with the end of the insulating rope 7 close to the wire 13 to be hung, and then slowly loosens the insulating rope 7. Relying on the elastic force of the elastic member 9 itself, the two insulating rods 2 are tightened inward, and the end with the insulating rope 7 is tightened on the wire 13 to complete the grounding work.

[0035] When it is necessary to dismantle the device, the staff pulls the insulating rope 7 by hand, separates the section with the insulating rope 7 from the conductor 13 by pulling force, swings it to change direction, and then slowly loosens the insulating rope 7. At this time, the grounding structure 3 with one end of the guide plate 5 will automatically fall off according to the loosening of the insulating rope 7 because there is no elastic pressing piece 6. Then the insulating rope 7 is manually dragged to retract the device, and the recycling is completed.

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
