Description

Technical Field

[0001] This utility model belongs to the field of grounding device technology, and more specifically, it relates to a grounding device for overhead lines. Background Technology

[0002] When performing maintenance or other construction work on overhead lines, a grounding rod must be installed on the overhead line, and the current is conducted to the ground through an oxygen-free copper wire on one side to ensure construction safety. The grounding rod is equipped with a clamp, which is usually manually rotated to clamp the transmission line and prevent the clamp from separating from the transmission line.

[0003] Existing grounding rods typically use a screw-driven rotation method to move a clamping plate and secure the grounding ring installed on the overhead line. During this rotation, the numerous rotations increase the time spent working at heights, potentially leading to worker fatigue, increased risk of falls, or even the grounding rod falling during operation. Therefore, this paper researches and improves upon the existing structure and its shortcomings to provide a grounding device for overhead lines, aiming to achieve greater practical value.

A bottom cover is threaded to the bottom of the hollow pole, and a handle is provided at the bottom of the bottom cover. A top cover is threaded to the top of the hollow pole, and a fixing clamp is provided at the top of the top cover. A movable clamping plate is slidably connected inside the fixing clamping plate. A connecting hole is provided on one side of the handle, bottom cover, hollow pole, top cover, and fixing clamping plate. A handle is slidably connected inside the handle, and a connecting rod is connected to one end of the handle. The connecting rod passes sequentially through the connecting hole of the handle, bottom cover, hollow pole, top cover, and fixing clamping plate, and is fixedly connected to the movable clamping plate.

A limiting ring is provided on the outside of the connecting rod and directly above the fixing ring. A spring is fitted on the outside of the connecting rod, and the two ends of the spring are respectively abutted against the limiting ring and the fixing ring.

[0007] As a preferred technical solution of this utility model, the inner sides of the handle are provided with sliding grooves, and the sides of the grip are provided with guide blocks that slide corresponding to the sliding grooves.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a grounding device for overhead lines, including a hollow pole 1, wherein the hollow pole 1 is made of insulating material, a bottom cover 2 is threadedly connected to the bottom end of the hollow pole 1, a handle 3 is provided at the bottom end of the bottom cover 2, a top cover 4 is threadedly connected to the top end of the hollow pole 1, a fixing clamp 5 is provided at the top end of the top cover 4, and a movable clamp 6 is slidably connected inside the fixing clamp 5. A connecting hole is opened on one side of the handle 3, the bottom cover 2, the hollow pole 1, the top cover 4 and the fixing clamp 5, and a handle 7 is slidably connected inside the handle 3. A connecting rod 8 is connected to one end of the handle 7, and the connecting rod 8 passes through the connecting hole of the handle 3, the bottom cover 2, the hollow pole 1, the top cover 4 and the fixing clamp 5 in sequence, and is fixedly connected to the movable clamp 6.

[0026] The hollow rod 1 has a fixing ring 9 inside, and the connecting rod 8 is slidably connected inside the fixing ring 9. A limit ring 10 is provided on the outside of the connecting rod 8 and directly above the fixing ring 9. A spring 11 is fitted on the outside of the connecting rod 8, and the two ends of the spring 11 are respectively abutted against the limit ring 10 and the fixing ring 9. The cooperation of the fixing ring 9, the limit ring 10 and the spring 11 can push the connecting rod 8 and the movable clamp 6 to automatically reset, so that the movable clamp 6 can be tightly fitted and installed on the grounding ring on the outside of the overhead line, which improves the convenience and reliability of the device.

[0027] The handle 3 has grooves on both sides, and the handle 7 has guide blocks 17 on both sides that slide corresponding to the grooves. Both the handle 7 and the handle 3 are made of plastic, and both have anti-slip textures on one side. The guide blocks 17 guide the movement of the handle 7 and prevent it from deviating during movement. The plastic material of the handle 7 and the handle 3 maintains the overall insulation properties of the device, further ensuring the safety of the operator. The anti-slip textures on the surface increase the friction between the hand and the handle 3 and handle 7, improving the stability of operation.

[0028] The fixed clamp 5 has two sets of sliding grooves on one side of its vertical section, and the movable clamp 6 has a slider 12 on one side that slides in accordance with the two sets of sliding grooves. This provides a stable track for the sliding of the movable clamp 6, restricts the direction of movement of the movable clamp 6, and ensures that the movable clamp 6 can slide smoothly and steadily within the fixed clamp 5.

[0029] The handle 3 has a threaded hole on one side, and a wing bolt 13 is threaded into the threaded hole. The handle 7 has a guide ring 14 corresponding to the wing bolt 13 on one side. One end of the wing bolt 13 extends into the guide ring 14 and fits against its inner wall. After the grounding ring is clamped, the handle 7 can be further fixed by rotating the wing bolt 13 to ensure the reliability and stability of the grounding connection.

[0030] The fixed clamp 5 and the movable clamp 6 each have corresponding arc-shaped limiting grooves on opposite sides. The top of the movable clamp 6 is integrally formed with anti-slip protrusions. One side of the fixed clamp 5 is threaded with an oxygen-free copper wire 15, which can increase the contact area between the two and the grounding ring and provide a more stable fixing effect. The oxygen-free copper wire 15, with its excellent conductivity, can ensure that the grounding current is quickly and stably introduced into the ground. The threaded connection method facilitates the installation and replacement of the oxygen-free copper wire 15 and makes it easy for later maintenance.

[0031] The handle 7 and the movable clamping plate 6 are each provided with a stud 16 on one side, and the two ends of the connecting rod 8 are provided with threaded holes. Both sets of studs 16 are threaded into the threaded holes. When the device needs maintenance, the handle 7, the movable clamping plate 6 and the connecting rod 8 can be quickly separated, which facilitates the inspection or replacement of individual components and improves the maintainability of the device.

[0032] The working principle of this embodiment:

[0033] When using the grounding device, the operator first grasps the handle 3 and pulls the handle 7. The handle 7 moves the connecting rod 8 to one side of the handle 7. At the same time, since the connecting rod 8 is fixedly connected to the movable clamp 6, the movable clamp 6 moves towards the handle 7 within the groove of the fixed clamp 5. During the movement, the spring 11 is compressed, increasing the distance between the movable clamp 6 and the fixed clamp 5. Then, the grounding ring installed on the outside of the overhead line is placed in the arc-shaped limiting groove between the two. Then, the handle 7 is released. Under the action of the spring 11, the connecting rod 8 moves the movable clamp 6 upward, so that the grounding ring fits tightly against the arc-shaped limiting groove between the movable clamp 6 and the fixed clamp 5. Then, the wing bolt 13 on one side of the handle 3 is rotated to change the position of the handle 7 within the handle 3, thereby firmly clamping the grounding ring. At the same time, the oxygen-free copper wire 15 threaded on one side of the fixed clamp 5 can introduce the generated current into the ground, realizing the grounding protection function and ensuring the normal operation of the operator.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
