Description

Technical Field

[0001] The present invention relates to the field of power system working tools, and more particularly to a grounding wire capable of rotating at multiple angles. Background Art

[0002] 10kV overhead lines are often located in outdoor environments and are susceptible to environmental influences, leading to line failures. Frequent power outages and maintenance are required. To ensure the personal safety of construction workers and prevent the risk of sudden power-on, the overhead lines must be subjected to safety measures such as three-phase short-circuiting and grounding. In existing technologies, the grounding clamp is fixedly connected to the insulating rod, and the direction of the grounding clamp cannot be changed. When encountering tension, corner, terminal tower, or other non-horizontal conductors, the conductor hanging direction is perpendicular to the insulating rod. Maintenance personnel must reach the insulator to hang and remove the grounding wire. This operation method increases labor intensity and also poses many unsafe factors, posing hidden dangers to production safety. Summary of the Invention

[0003] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a grounding wire that can swing at multiple angles, adds components such as an adjustment seat and a flexible shaft, and adjusts the rotation angle between the adjustment seat and the grounding wire clamp. The grounding wire clamp can be rotated at multiple angles to adapt to the conditions of tension resistance, corners, terminal poles or other non-horizontal conductor grounding wires.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A grounding wire capable of rotating at multiple angles includes a grounding wire clamp, a drive screw, and an insulating rod. The insulating rod is connected to a clamp head via the drive screw. The grounding wire clamp includes a clamp head, a hook head, a hook arm, and a hook base. The grounding wire clamp is also provided with a terminal for connecting the grounding wire. The grounding wire clamp also includes an adjustment seat for adjusting the rotation angle of the grounding wire clamp. The adjustment seat is an L-shaped structure, one end of which is rotationally connected to the hook base and the other end is assembled and connected to the drive screw. A flexible shaft for accommodating angular rotation is also provided between the clamp head and the drive screw. The multi-angle rotation of the grounding wire clamp is achieved by rotating the adjustment seat and the hook base. The flexible shaft is used to connect the clamp head and the drive screw to accommodate the connection requirements for angular rotation of the grounding wire clamp.

[0006] Furthermore, the adjustment seat and the hook base are connected via a rotating shaft, which is mainly used to connect and fix the adjustment seat and the hook base.

[0007] Furthermore, the rotating shaft is a hexagonal bolt or a countersunk bolt.

[0008] Furthermore, the rotating shaft is also provided with a butterfly nut for locking. When a hexagonal bolt or a countersunk bolt is used as the rotating shaft for connection, a butterfly nut needs to be used on the threaded end of the bolt to lock and fix it to prevent the adjustment seat and the hook base from falling off.

[0009] Furthermore, the connection between the adjustment base and the hook base is equipped with a gear structure for mutual locking. The gear structures on the adjustment base and the hook base are each equipped with mutually cooperating gear structures, primarily to strengthen the locking and interlocking engagement between the adjustment base and the hook base. To adjust the angle of the grounding clamp, loosen the butterfly nut to disengage the gear teeth between the adjustment base and the hook base. Then, rotate the grounding clamp to the desired angle, reengage the gear teeth, and tighten the butterfly nut to fully lock the adjustment base and the hook base, preventing them from rotating on their own.

[0010] Furthermore, the flexible shaft is a universal flexible shaft. The wire clamp chuck and the drive screw are connected by a universal flexible shaft. When the grounding wire clamp is rotated, the universal flexible shaft can bend to adapt to the angular rotation. Then, the drive screw is twisted to tighten the universal flexible shaft, ensuring that the wire clamp chuck clamps the wire.

[0011] Furthermore, a threaded through hole is provided at the assembly position of the adjustment seat and the transmission screw, and the adjustment seat and the transmission screw are connected in a threaded manner. The upward and downward movement of the wire clamp chuck is controlled by the assembly connection between the transmission screw and the threaded through hole.

[0012] Furthermore, a guide head for guiding the wire clamp chuck is provided on one side of the wire clamp chuck.

[0013] Furthermore, the hook arm is provided with a guide groove for limiting the vertical linear motion of the guide head. The guide groove on the hook arm is used to cooperate with the guide head on the wire clamp chuck. Due to the uncertainty of the bending direction of the universal flexible shaft, the constraint between the guide head and the guide groove limits the vertical linear motion of the wire clamp chuck, ensuring that the wire clamp chuck can clamp the wire tightly.

[0014] Furthermore, the tooth profile of the gear tooth structure is rectangular.

[0015] Compared with the prior art, the beneficial effects of the invention are: the present invention includes components such as a grounding wire clamp, a transmission screw, an insulating rod, an adjustment seat and a universal flexible shaft. One end of the adjustment seat is rotatably connected to the grounding wire clamp, and the other end is assembled and connected to the transmission screw. By adjusting the rotation angle between the adjustment seat and the grounding wire clamp, the grounding wire clamp can be rotated at multiple angles to adapt to the conditions of tension resistance, corners, terminal poles or other non-horizontal conductor grounding wires, and has greater adjustment flexibility.

[0020] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0021] Example 1

[0022] like Figure 1 As shown, this embodiment provides a grounding wire that can be rotated at multiple angles, including a grounding wire clamp 1, a transmission screw 2 and an insulating rod 3. The insulating rod 3 is connected to the wire clamp chuck 11 through the transmission screw 2. The grounding wire clamp 1 includes the wire clamp chuck 11, a hook head 12, a hook arm 13 and a hook base 14. The grounding wire clamp 1 is also provided with a terminal 15 for connecting the ground wire. This embodiment also includes an adjustment seat 4 for adjusting the rotation angle of the grounding wire clamp 1. The adjustment seat 4 is an L-shaped structure, one end of which is rotatably connected to the hook base 14, and the other end is assembled and connected to the transmission screw 2. A flexible shaft for adapting to angular rotation is also provided between the wire clamp chuck 11 and the transmission screw 2. Among them, the multi-angle rotation of the grounding wire clamp 1 is achieved by the rotation between the adjustment seat 4 and the hook base 14. At the same time, the flexible shaft is used to connect the wire clamp chuck 11 and the transmission screw 2 to meet the connection requirements of the angular rotation of the grounding wire clamp 1.

[0023] Specifically, the adjusting seat 4 and the hook base 14 are connected via a rotating shaft 6. The rotating shaft 6 is mainly used for connecting and fixing the adjusting seat 4 and the hook base 14.

[0024] Specifically, the rotating shaft 6 is a hexagonal bolt or a countersunk bolt.

[0025] Specifically, the rotating shaft 6 is also provided with a butterfly nut 7 for locking. When the rotating shaft 6 is connected with a hexagonal bolt or a countersunk bolt, it is necessary to use a butterfly nut 7 to lock and fix it at the threaded end of the bolt to prevent the adjustment seat 4 and the hook base 14 from falling off.

[0026] Specifically, the connection between the adjustment seat 4 and the hook base 14 is provided with a gear structure 8 for clamping each other. The adjustment seat 4 and the hook base 14 are respectively provided with a gear structure 8 that can cooperate with each other, mainly to strengthen the clamping engagement between the adjustment seat 4 and the hook base 14.

[0027] Specifically, the flexible shaft is a universal flexible shaft 5. The universal flexible shaft 5 is used to connect the wire clamp chuck 11 and the transmission screw 2. When the grounding wire clamp 1 is rotated, the universal flexible shaft 5 can bend to adapt to the angular rotation. Then, the transmission screw 2 is twisted to tighten the universal flexible shaft 5, ensuring that the wire clamp chuck 11 clamps the wire.

[0028] Specifically, a threaded through hole 41 is provided at the assembly position of the adjustment seat 4 and the transmission screw 2, and the connection mode of the adjustment seat 4 and the transmission screw 2 is a threaded connection. Through the assembly connection between the transmission screw 2 and the threaded through hole 41, the clamp chuck 11 is controlled to move up and down.

[0029] Specifically, a guide head 111 for guiding the wire clamp chuck 11 is further provided on one side of the wire clamp chuck 11 .

[0030] Specifically, the hook arm 13 is provided with a guide groove 131 for limiting the vertical linear motion of the guide head 111. The guide groove 131 on the hook arm 13 is used to cooperate with the guide head 111 on the wire clamp chuck 11. Since the bending direction of the universal flexible shaft 5 is uncertain, the constraint between the guide head 111 and the guide groove 131 limits the vertical linear motion of the wire clamp chuck 11, ensuring that the wire clamp chuck 11 can clamp the wire.

[0031] Specifically, the tooth profile of the gear tooth structure 8 is rectangular.

[0032] When grounding a tension, corner, terminal tower, or other non-horizontal conductor, the specific steps are as follows: First, loosen the butterfly nut 7 to disengage the gear teeth between the adjustment seat 4 and the hook base 14. Then, rotate the grounding clamp 1 to the appropriate angle, re-engage the gear teeth, and tighten the butterfly nut 7 until the adjustment seat 4 and the hook base 14 are completely locked and cannot rotate on their own, completing the angular rotation. Next, hang the hook head 12 on the corresponding conductor. As the grounding clamp 1 rotates, the universal flexible shaft 5 bends to accommodate the angular rotation. Twist the drive screw 2, which pushes the clamp head 11 upward through the universal flexible shaft 5 until the clamp head 11 is pressed against the conductor. Due to the constraint between the guide slot 131 on the hook arm 13 and the guide head 111 on the clamp head 11, the clamp head 11 always maintains a straight line movement up and down, ensuring that the clamp head 11 and the hook head 12 cooperate to press the conductor, completing the grounding operation.

[0033] Example 2

[0034] like Figure 1 As shown, embodiment 2 provides a grounding wire that can rotate at multiple angles. The structure is similar to that in embodiment 1, but the difference lies in different application conditions.

[0035] When grounding a standard horizontal conductor, loosen the butterfly nut 7 to disengage the gear teeth between the adjustment base 4 and the hook base 14. Keeping the grounding clamp 1 vertically upward, tighten the butterfly nut 7 to fully engage the adjustment base 4 and the hook base 14. Next, hook the hook head 12 onto the corresponding conductor. Since the universal flexible shaft 5 remains vertically upward, twist the drive screw 2 to push the universal flexible shaft 5 and the wire clamp chuck 11 upward until they are both compressed, completing the grounding operation.

[0036] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
