Technical Field

[0001] This application relates to the field of power auxiliary tools technology, and in particular to a high-altitude grounding wire installation device. Background Technology

[0002] When performing maintenance work on de-energized electrical equipment in a substation, it is essential to take protective measures to ensure the personal safety of the workers. Before starting the work, grounding wires must be installed on both sides of the equipment to be maintained, with one end of the grounding wire grounded and the other end connected to a conductor.

[0003] When installing grounding wires on high-voltage electrical equipment located at elevated positions, workers use ordinary insulated poles to support the grounding wires and complete the installation. Due to the considerable length of the insulated poles and the weight of the grounding wires, installing grounding wires at high locations is difficult for a single worker to complete. The difficulty is further increased in windy weather. During installation, if the insulated pole falls towards the live equipment, it could cause an accident.

[0004] Therefore, how to reduce the difficulty of installing grounding wires at high altitudes is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In some embodiments, a through hole is provided on one side wall of the snap-fit ​​groove, and the locking mechanism includes a locking link and a locking block. One end of the locking link passes through the through hole and is inserted into the snap-fit ​​groove. The locking block is connected to the end of the locking link located in the snap-fit ​​groove. The through hole has a support surface facing the snap-fit ​​groove. There is a force-bearing surface between the locking block and the locking link facing the through hole. A locking spring is provided on the outer periphery of the locking link. The locking spring is located between the support surface and the force-bearing surface to push the locking block to fit against the side wall of the snap-fit ​​groove away from the through hole.

[0008] In some embodiments, the locking block has a guide ramp on the side away from the bottom of the latching groove, and the distance between the guide ramp and the bottom of the latching groove gradually increases along the direction close to the through hole.

[0009] In some embodiments, the sidewall of the snap-fit ​​groove is provided with conductive springs for engaging with the wires, and the conductive springs on both sides of the snap-fit ​​groove are located below the through hole.

[0010] In some embodiments, the traction part is an insulated traction rope, which is connected to the top of the side wall of the snap-fit ​​groove away from the through hole.

[0011] In some embodiments, the device body has two parallel snap-fit ​​slots with a central partition wall between them, and a through hole is provided on the side wall of the snap-fit ​​slot away from the central partition wall.

The end of the directional push rod away from the downward push rod is hinged to a locking link. The downward push rod is movably connected to the device body. The end of the downward push rod away from the directional push rod is abutted against the lower side of the unlocking push block.

[0014] In some embodiments, the directional push rod is L-shaped, with the vertex of the included angle of the directional push rod connected to the device body, and both sides of the included angle of the directional push rod extending away from the device body.

[0015] In some embodiments, the unlocking push block is connected to an insulated pull-down cord.

[0025] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of a specific embodiment of the high-altitude grounding wire installation device provided in this application;

[0028] Figure 3 for Figure 1 Side view of the grounding wire installation device at mid-to-high altitude.

[0029] The high-altitude grounding wire installation device provided in this application has the following structure: Figure 1 As shown, the device includes a main body 1, a traction unit, a locking mechanism, and an unlocking mechanism. The main body 1 is a conductor, and a snap-fit ​​groove 11 is provided on one side of the main body 1, penetrating both side walls of the main body 1. Therefore, the snap-fit ​​groove 11 forms a three-sided open structure, allowing the wire to enter and adhere to the bottom of the snap-fit ​​groove 11. The side of the main body 1 away from the opening of the snap-fit ​​groove 11 is connected to the end of the ground wire 9 by welding or other means. A traction unit is provided at the top of the side wall of the snap-fit ​​groove 11. The traction unit can be a traction rope 7, which, after passing around the wire via an insulating rod, pulls the main body 1 upward, causing the wire to enter the snap-fit ​​groove 11. The locking mechanism is located on the side wall of the snap-fit ​​groove 11 at a preset distance from the bottom of the snap-fit ​​groove 11, a distance greater than the wire diameter. After the wire enters the snap-fit ​​groove 11, the locking mechanism closes the opening of the snap-fit ​​groove 11, thereby confining the wire within the snap-fit ​​groove 11. The device body 1 is also equipped with an unlocking mechanism, which is connected to the locking mechanism. After the operation is completed, the unlocking mechanism causes the locking mechanism to move, thereby releasing the lock on the wire and allowing the high-altitude grounding wire installation device to be installed.

[0030] In this embodiment, when setting a ground wire 9 for a high-altitude conductor, it is necessary to connect the high-altitude conductor to the ground wire 9. The connection process is difficult and carries significant safety risks. The ground wire setting device, through a locking mechanism that cooperates with the locking slot 11, directly confines the conductor within the locking slot 11, reducing the difficulty of connecting the conductor to the ground wire 9, and thus reducing the difficulty of setting a high-altitude ground wire 9.

[0031] In some embodiments, a through hole is provided on one side wall of the snap-fit ​​groove 11, through which it is connected to the device body 1. For example... Figure 1 As shown, the locking mechanism includes a locking link 3 and a locking block 2. One end of the locking link 3 passes through a through hole and is inserted into the locking groove 11. The locking block 2 is connected to the end of the locking link 3 located in the locking groove 11 and extends in a direction parallel to the locking link 3. The diameter of the locking link 3 is smaller than the diameter of the inscribed circle of the end face of the locking block 2, thus creating a force-bearing surface between the locking block 2 and the locking link 3 facing the through hole. The diameter of the section from the middle of the through hole to the locking groove 11 is larger than the diameter of the circumscribed circle of the cross-section of the locking block 2. The diameter of the end from the middle of the through hole to the outside of the device body 1 is larger than the diameter of the locking link 3 and smaller than the diameter of the circumscribed circle of the cross-section of the locking block 2, thereby forming a support surface facing the locking groove 11 within the through hole. A locking spring 4 is provided on the outer periphery of the locking link 3. The locking spring 4 is located between the support surface and the force-bearing surface. The spring force of the locking spring 4 can push the locking block 2, causing it to fit against the side wall of the locking groove 11 away from the through hole. When the lock is released, the locking block 2 can enter the through hole, thus making way for the wire to leave the snap hole.

[0032] In some embodiments, the latching groove 11 of the device body 1 is normally in a locked state, that is, the locking block 2 is in contact with the side wall of the latching groove 11 away from the through hole. The locking block 2 has a guide slope on the side away from the bottom of the latching groove 11, such as... Figure 1 As shown, the distance between the guide ramp and the bottom of the locking groove 11 gradually increases along the direction approaching the through hole. When the wire contacts the guide ramp, a force perpendicular to the ramp is applied to the guide ramp, causing the locking block 2 to move towards the through hole, thereby allowing the wire to enter between the locking block 2 and the bottom of the locking groove 11. The side of the locking block 2 near the bottom of the locking groove 11 is perpendicular to the side wall of the locking groove 11, further reducing the risk of the wire disengaging from the locking groove 11.

[0033] In some embodiments, the device body 1 has two snap-fit ​​slots 11 arranged in parallel, forming a "mountain" shaped structure. A central partition wall separates the two snap-fit ​​slots 11, and a side wall is formed on the side of each snap-fit ​​slot 11 away from the central partition wall. A through hole is provided on the side wall. Figure 3 As shown, the height of the central partition wall is higher than that of the side walls, and the width of the central partition wall is smaller than that of the side walls. The two sides of the side walls are arc-shaped. During the traction process, the central partition wall first contacts the wire, followed by the arc-shaped side walls. With further traction, the device body 1 rotates relative to the wire, causing the wire to fall into a snap-fit ​​groove 11.

[0034] In some embodiments, the sidewall of the snap-fit ​​groove 11 is provided with a conductive spring 13, which is electrically connected to the device body 1. For example... Figure 1 As shown, conductive springs 13 are provided on both sides of the snap-fit ​​groove 11, and the conductive springs 13 are located below the through hole. The missile springs can be made of arc-shaped copper sheets. Both ends of the conductive springs 13 are connected to the side walls of the snap-fit ​​groove 11, and the middle part of the conductive springs 13 protrudes for contact with the wire. Of course, users can also use conductive springs 13 with other structures as needed, which is not limited here.

[0035] In some embodiments, the traction part is an insulated traction rope 7, which may be made of materials such as polyester or nylon. The insulated traction rope 7 is connected to the top of the middle partition wall, and the connection method between the two can refer to the prior art, which will not be described in detail here.

[0036] In some embodiments, the unlocking mechanism includes an unlocking pusher 8 and a linkage assembly. For example... Figure 1As shown, the device body 1 has a strip-shaped hole 12, which is located below the central partition wall and extends in a direction parallel to the central partition wall. The unlocking push block 8 is inserted into the strip-shaped hole 12. A guide groove can be provided on the side wall of the strip-shaped hole 12, and the unlocking push block 8 can be provided with a guide protrusion that cooperates with the guide groove, thus allowing the unlocking push block to move along the strip-shaped hole 12. Alternatively, the user can use a bolt to engage with the outer periphery of the strip-shaped hole 12 for limiting, or use other limiting methods in the prior art to restrict the movement direction of the unlocking push block 8. The connecting rod assembly is connected to the locking connecting rod 3 at one end located outside the locking groove 11, and also cooperates with the unlocking push block 8. When the unlocking push block 8 moves downward, the connecting rod assembly drives the locking connecting rod 3 to move away from the central partition wall, thereby creating a gap between the locking block 2 and the central partition wall, releasing the locking state.

[0037] In some embodiments, the linkage assembly includes a directional push rod 5 and a downward push rod 6. For example... Figure 1 and Figure 2 As shown, the downward push rod 6 is positioned perpendicular to the central partition wall and below the unlocking push block 8. The reversing push rod 5 connects the locking link 3 and the downward push rod 6. The middle part of the reversing push rod 5 is hinged to the device body 1 via a rotation axis, the lower end of the reversing push rod 5 is hinged to one end of the downward push rod 6, and the upper end of the reversing push rod 5 is hinged to the locking link 3. The downward push rod 6 is also movably connected to the device body 1, and remains perpendicular to the central partition wall during movement. The connection method between the downward push rod 6 and the device body 1 is similar to that of the unlocking push block 8 and will not be described further here. The end of the downward push rod 6 away from the reversing push rod 5 is in contact with the lower side of the unlocking push block 8. When the unlocking push block 8 moves downward, it pushes the downward push rod 6 downward, causing the downward push rod 6 to rotate around the rotation axis, thereby moving the reversing push rod away from the central partition wall and thus converting the locking mechanism to the unlocked state. Additionally, since the diameter of the through hole is larger than the diameter of the locking link 3, when the locking link 3 moves away from the central partition wall, the locking block 2 will also tilt, such as... Figure 2 As shown, the end of the locking block 2 near the central partition wall is larger than the end of the locking block 2 away from the central partition wall at the bottom of the locking groove 11. The lower side of the locking block 2 can serve as a guide for the wire, thus facilitating the wire's disengagement from the locking groove 11. Of course, users can also use other unlocking mechanisms as needed, such as using a micro motor and gears to drive the locking linkage 3 to complete the unlocking, which is not limited here.

[0038] In some embodiments, the deflector push rod 5 is L-shaped. For example... Figure 1 As shown, the included angle of the directional push rod 5 is located in the middle of the directional push rod 5, and the vertex of this included angle is hinged to the device body 1 through a rotation axis. Both sides of the included angle of the directional push rod 5 extend away from the device body 1, and the ends of the two sides are respectively hinged to the down push rod 6 and the locking link 3.

[0039] In some embodiments, the unlocking push block 8 is connected to an insulated pull-down rope. When the high-level grounding device is connected to the conductor, the grounding wire 9 is usually located below the device body 1. The operator can pull the insulated pull-down rope to move the unlocking push block 8 downwards. Of course, the user can also use other methods to move the unlocking push block 8 downwards, such as by pushing the unlocking push block 8 with an electric telescopic rod, etc., which is not limited here.

[0040] In this embodiment, in the high-altitude grounding wire installation device, the unlocking push block 8 pushes the downward push rod 6 to move downward, and the reversing push rod 5 converts the downward movement into horizontal movement, thereby unlocking the high-altitude grounding wire installation device. The high-altitude grounding wire installation device has a simple structure, is easy to assemble and disassemble, and reduces the difficulty of connecting the grounding wire 9 to the high-altitude conductor, thus reducing the safety risks of the operation.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application.
