Description

Technical Field

[0001] The utility model relates to the technical field of power transmission lines, in particular to a ground wire auxiliary device for hanging a power transmission line. Background Art

[0002] A ground wire, also known as a ground wire, ground conductor, or ground spike, is a conductive connection used in power systems, electrical equipment, and buildings to conduct electrical current to the ground for electrical safety and protection.

[0003] When power workers are repairing transmission lines, they often use ground rods, which are auxiliary devices for hanging ground wires, to hang on the transmission lines. When the faulty transmission line suddenly receives power during the repair process, the current is led to the ground through the ground wire connected to the ground rod to ensure the safety of the workers. However, most of the existing ground rods on the market are of fixed length. When the hanging position is too high, it is difficult for workers to hang them. In addition, the ground rods are often clamped on the transmission line by rotating the threaded rod to move the clamping block, which is very cumbersome to operate.

[0004] For example, Chinese patent publication number CN214378895U discloses a grounding rod including a grounding rod body and a grounding rod head. An impact joint is welded on the top of the grounding rod body, and the impact joint is provided with an internal thread; handles are welded on both sides of the grounding rod body below the impact joint, and insulating sleeves are connected to the handles on both sides, and the two insulating sleeves are connected to a first luminous strip and a first reflective strip; a transverse screw is welded on the grounding rod body below the handle, a washer is provided on the screw and a nut is threadedly connected, and a stop nut is connected to the screw outside the nut. An impact joint is added at the top to facilitate the connection of the impact head. A handle is added to facilitate operation, avoid hitting the hands of construction workers, and easily pull out the grounding rod. An insulating sleeve is provided on the handle, which has luminous and reflective functions at night to improve safety. The design of the screw and nut is convenient for connecting the ground wire, and the design of the stop nut can prevent the nut from moving outward and falling. However, there are still problems such as "the length is fixed, and it is difficult for workers to hang it when the hanging position is too high, and the grounding rod is clamped on the transmission line by rotating the internal thread of the impact joint, which is very cumbersome to operate."

[0005] Therefore, we proposed a transmission line grounding wire auxiliary device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] Reference Figure 1-Figure 3 The auxiliary device for hanging a ground wire on a power transmission line comprises a sleeve 1, a rotating handle 2 is rotatably connected to the lower end of the sleeve 1, a threaded rod 3 is fixedly connected to the upper end of the rotating handle 2, a connecting rod 4 is threadedly sleeved on the upper end of the threaded rod 3, and two rectangular sliders 5 are fixedly connected to the cylindrical surface of the connecting rod 4, and two sliding grooves correspondingly arranged in front and back are provided on the inner wall of the cylindrical surface of the sleeve 1, and the two rectangular sliders 5 are slidably connected in the corresponding sliding grooves. The staff can hold the sleeve 1 with one hand and rotate the rotating handle 2 with the other hand to rotate the threaded rod 3, so that the connecting rod 4 threadedly sleeved on the upper end of the threaded rod 3 moves up or down, thereby extending above the sleeve 1 or shrinking into the sleeve 1. The two rectangular sliders 5 slide up or down in the sliding groove in the sleeve 1, and play a limiting role on the connecting rod 4. A hanging component is provided on the connecting rod 4, and the hanging component includes a hook block 6 and a clamping block 8, which are used to clamp the power transmission line.

[0023] The outer wall of the cylindrical surface of the sleeve 1 is fixedly connected with two first rectangular blocks 9 correspondingly arranged on the left and right, and a telescopic rod 10 is connected to the two first rectangular blocks 9 by common rotation. The upper end of the connecting rod 4 is fixedly connected with a hook block 6, and two movable openings 7 are provided on the rear inner wall of the hook block 6. A clamping block 8 is provided above the connecting rod 4, and an opening is provided on the side of the clamping block 8. The clamping block 8 passes through the two movable openings 7 and is slidably connected therewith. A spring 11 is provided in the opening provided on the side of the clamping block 8, and one end of the spring 11 is fixedly connected to the front inner wall of the clamping block 8 and the other end is fixedly connected to the rear inner wall of the hook block 6. The rear end of the clamping block 8 is fixedly connected with two second rectangular blocks 12 correspondingly arranged on the left and right, and the telescopic end of the telescopic rod 10 is connected to the two second rectangular blocks 12 by common rotation. The front inner wall of the hook block 6 and the front end of the clamping block 8 are both provided with wavy patterns composed of several correspondingly arranged arc surfaces. A pressing handle 13 is fixedly connected to the lower end of the telescopic rod 10. In the initial state, the front end of the clamping block 8 is fitted with the hook block 6 due to the elastic force of the spring 11, and the front end of the clamping block 8 is arranged corresponding to the wavy texture of the front inner wall of the hook block 6. When the pressing handle 13 is pressed in the direction of the rotating handle 2, the telescopic rod 10 is tilted, and the clamping block 8 is pulled backward along the movable opening 7 by the telescopic end of the telescopic rod 10, and the spring 11 is squeezed backward by the clamping block 8. At this time, the position between the front inner wall of the hook block 6 and the front end of the clamping block 8 can be used to hook the wire. When the wire fits with the front end of the clamping block 8 or the arc surface of the wavy texture of the front inner wall of the hook block 6, the pressing handle 13 is released, and the clamping block 8 moves forward due to the elastic reset of the spring 11, thereby clamping the transmission wire, so that the device is hung on the transmission wire.

[0024] A connection port 14 is provided at the rear end of the hook block 6 above the clamping block 8. The connection port 14 is fixedly connected to the ground wire, and the clamping block 8, the hook block 6, and the connection port 14 are all made of copper or aluminum, and have good conductivity. If there is a sudden current transported through the transmission line, it is transmitted to the ground wire through the clamping block 8, the hook block 6, and the connection port 14, thereby safely guiding the current to the ground. The connecting rod 4 is made of ceramic material, and the sleeve 1, the first rectangular block 9, the second rectangular block 12, and the telescopic rod 10 are all made of carbon fiber composite materials. Both ceramics and carbon fiber composite materials have good insulation effects to prevent workers from getting electric shock when using the device.

[0025] When using the utility model, the operator can first adjust the device to an appropriate length by rotating the rotating handle 2 to raise or lower the connecting rod 4, and then press the pressing handle 13 in the direction of the rotating handle 2 to separate the clamping block 8 and the hook block 6 from the fitted state, and then hook the hook block 6 on the position where the ground wire needs to be hung on the transmission line. When the transmission wire fits with the arc surface of the hook block 6 or the clamping block 8, the pressing handle 13 is released, and the clamping block 8 is reset due to the effect of the spring 11 to clamp the transmission wire, thereby hanging the device on the transmission line. If the transmission wire suddenly has an electric current transported to the ground wire fixedly connected through the connecting port 14, it will be safely guided to the ground to prevent it from causing electric shock hazards to the operator, thereby protecting the operator's safety.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
