Technical Field

[0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to an adjustable grounding wire and a use method thereof. Background Art

[0002] As one of the key measures for the safe operation of power equipment, the grounding wire has the core function of ensuring that the equipment casing is not electrified, thereby effectively preventing electric shock accidents. By connecting the equipment to the ground, the grounding wire can quickly conduct the fault current or residual charge on the equipment into the ground, providing safety protection for power equipment and personnel.

[0003] In the actual working environment, the challenges faced by power workers are particularly complex. The dense interweaving of equipment lines and the limitations of the working space require each grounding operation to be precise and efficient. The grounding wire, as an important link between the equipment and the earth, is of self-evident importance. It must not only be able to quickly conduct the fault current on the equipment to the earth to ensure the safety of equipment and personnel, but also have good conductivity and durability.

[0004] However, traditional grounding rods, such as double-spring, spiral and clamp types, are often too fixed in design and lack sufficient flexibility and adjustability. This means that in complex and changeable equipment lines, workers may need to spend more time and energy to find a suitable grounding position, and sometimes even cannot perform effective grounding operations due to space limitations. This not only affects work efficiency, but also increases safety hazards during the operation process. Therefore, it needs to be improved and optimized. Summary of the invention

The rotating rod 2 and the worm are designed to be cross-designed in a vertical direction. The top end of the rotating rod 2 extends out of the installation bin and is rotatably connected to the installation bin. A worm wheel and a gear 2 are fixedly sleeved on the outer wall of the rotating rod 2, and the worm wheel is meshed with the worm.

[0008] A limiting groove is arranged on the outer wall of the fixing block 1 for installing the fixing block, a limiting plate is slidably installed inside the limiting groove, and the outer wall of the limiting plate is in contact with the outer wall of the limiting rod.

[0012] An outer screw is rotatably mounted on the inner wall of the wiring hook, and an inner screw is threadably mounted on the inner wall of the outer screw.

[0013] A clamping block is installed at one end of the inner screw, and the middle of the clamping block is designed as a groove.

[0014] Preferably, a metal hose is installed on the top of the insulating screw rod, and the top end of the metal hose is connected to the bottom end of the external screw rod.

[0015] A method for using an adjustable grounding wire, the method specifically comprising the following steps: S1, preliminary adjustment and limit: pull the limit plate to separate it from the limit rod, press the limit rod, the spring damping rod assembly is compressed, the triangular convex block is away from the inner slot of the inner tooth disc, rotate the knob one, drive the rotating rod one to rotate, and then drive the connecting rod to rotate and adjust, after the adjustment is completed, release the limit rod, the spring damping rod assembly rebounds, the triangular convex block is inserted into the inner slot of the inner tooth disc, and the preliminary limit is performed, and the limit plate is pulled to slide along the limit groove and contact the limit rod to limit again; S2, angle adjustment: rotate knob 2 to drive the worm to rotate, the worm meshes with the worm wheel, drives the rotating rod 2 and gear 2 to rotate, gear 2 meshes with gear 1, drives gear 1 to rotate, and then drives the wiring hook to rotate.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides an adjustable grounding wire, including an insulating rod 1, a circular ring block 101 is installed on the top outer wall of the insulating rod 1, a hand-held rubber handle 102 is installed on the bottom outer wall of the insulating rod 1, an insulating screw rod 2 is rotatably installed inside the insulating rod 1, a rotating handle 201 is fixedly sleeved on the bottom outer wall of the insulating screw rod 2, the top of the rotating handle 201 is rotatably connected to the bottom of the insulating rod 1, and the rotating handle 201 is located below the hand-held rubber handle 102, two fixed blocks 103 are installed on the outer wall of the circular ring block 101, and rotating rods 7 are rotatably installed on the outer walls of the two fixed blocks 103, respectively, and the two rotating rods 7 penetrate the two fixed blocks 103, and the two rotating rods 7 penetrate the two fixed blocks 103. Connecting rods 3 are respectively installed on the outer walls, and mounting blocks 4 are installed on the inner walls of the two connecting rods 3. Two fixing blocks 6 are installed on the outer wall of one of the fixing blocks 103. The two fixing blocks 6 are hingedly installed with a limiting rod 8 on one side close to each other. The limiting rod 8 is elastically connected to the outer wall of the adjacent fixing block 103 through a spring damping rod assembly 9. A knob 701 and an inner tooth disc 702 are fixedly sleeved on the outer wall of a rotating rod 7 close to the limiting rod 8. A triangular protrusion 801 is installed on the side of the limiting rod 8 close to the inner tooth disc 702. The triangular protrusion 801 is adapted to and fits with the inner tooth groove of the inner tooth disc 702, and a wiring hook 5 is rotatably installed inside the mounting block 4.

[0021] The limit rod 8 is elastically connected to the outer wall of the adjacent fixed block 103 through the spring damping rod assembly 9, so that the limit rod 8 can be elastically moved within a certain range, and a knob 701 and an inner tooth disk 702 are fixedly mounted on the outer wall of the rotating rod 7 close to the limit rod 8, so that the operator can drive the rotating rod 7 and the inner tooth disk 702 to rotate synchronously by rotating the knob 701, and a triangular protrusion 801 is installed on the side of the limit rod 8 close to the inner tooth disk 702, and the triangular protrusion 801 is adapted to and tightly fits with the inner tooth groove of the inner tooth disk 702. When the operator rotates the knob 701, the angle of the wiring hook 5 can be accurately adjusted. At the same time, the elastic force of the spring damping rod assembly 9 can keep the limit rod 8 in a stable position after the adjustment is completed.

[0022] like Figure 8As shown, a mounting bin 401 is mounted on the outer wall of the mounting block 4, and a rotating rod 12 and a worm 15 are rotatably mounted inside the mounting bin 401. The rotating rod 12 and the worm 15 are cross-designed in a vertical direction, and the top of the rotating rod 12 extends out of the mounting bin 401 and is rotatably connected to the mounting bin 401. A worm wheel 13 and a gear 14 are fixedly sleeved on the outer wall of the rotating rod 12, and the worm wheel 13 is meshed with the worm 15.

[0023] The rotating rod 12 and the worm 15 are rotatably installed inside the installation chamber 401, and the rotating rod 12 and the worm 15 are designed to be cross-designed in a vertical direction, so that the rotating rod 12 can simultaneously drive the worm wheel 13 and the gear 14 to move synchronously when rotating. The precise engagement of the worm wheel 13 and the worm 15 can efficiently transmit the rotational power of the worm 15 to the rotating rod 12, thereby realizing precise control of the entire grounding wire adjustment mechanism.

[0024] like Figures 5 to 7 As shown, a limiting groove 1031 is provided on the outer wall of the fixing block 103 for installing the fixing block 6, and a limiting plate 10 is slidably installed inside the limiting groove 1031. The outer wall of the limiting plate 10 fits with the outer wall of the limiting rod 8, and springs 11 are elastically installed on the side where the limiting plate 10 and the two fixing blocks 6 are close to each other, and the two springs 11 are designed to be symmetrically distributed.

[0025] By setting the limiting groove 1031, the limiting plate 10 can slide freely within a limited range, which ensures both the flexibility of adjustment and the compactness of the structure. At the same time, springs 11 are elastically installed on the side where the limiting plate 10 and the two fixed blocks 6 are close to each other, so that the reset ability of the limiting plate 10 is realized and the whole adjustment process is smoother and more stable. The two springs 11 are symmetrically distributed, which makes the structure more balanced and ensures the stability of the limiting plate 10 during the sliding process.

[0026] like Figure 8 As shown, one end of the worm 15 extends out of the installation chamber 401 and is rotatably connected to the installation chamber 401 , a knob 2 16 is fixedly sleeved on the outer wall of the worm 15 , and a gear 1 501 is installed at the bottom of the wiring hook 5 , and the gear 1 501 is meshed with the gear 2 14 .

[0027] One end of the worm 15 is cleverly extended out of the installation chamber 401 and is rotatably connected to the installation chamber 401, which not only ensures that the worm 15 can rotate smoothly, but also makes the entire structure more compact and reasonable. By rotating the knob 2 16, the angle of the wiring hook 5 can be accurately adjusted through the transmission of the worm 15, which effectively simplifies the operating steps. The gear 1 501 is precisely engaged with the gear 2 14 in the transmission system of the worm 15. The mutual engagement between the gears ensures the stability and reliability of the wiring hook 5 during the rotation process, making the adjustment process more stable and smooth, and greatly extending the service life of the equipment.

[0028] like Figure 3 to Figure 4 As shown, an outer screw 17 is rotatably mounted on the inner wall of the wiring hook 5, an inner screw 18 is threadedly mounted on the inner wall of the outer screw 17, a clamping block 19 is mounted at one end of the inner screw 18, the middle of the clamping block 19 is designed as a groove, a metal hose 20 is mounted on the top of the insulating wire rod 2, and the top end of the metal hose 20 is connected to the bottom end of the outer screw 17.

[0029] By threading the outer screw 17 and the inner screw 18, the stable movement of the inner screw 18 in the outer screw 17 is ensured. By setting the clamping block 19, not only the clamping force is enhanced, but also the wire can be clamped more firmly. The middle of the clamping block 19 is designed with a groove, which can better adapt to wires of different thicknesses, further improving the wide range of use and practicality. In addition, a metal hose 20 is installed on the top of the insulating screw rod 2, thereby enhancing the stability of the entire structure, and allowing the metal hose 20 to be flexibly bent and rotated to adapt to wires at different angles and positions. The top end of the metal hose 20 is connected to the bottom end of the outer screw 17 to ensure the continuity and stability of the rotation action, thereby further improving the effect of clamping the wire.

[0030] During operation of the present invention, first, the limit plate 10 is pulled to release the locking state between it and the limit rod 8, and then the limit rod 8 is pressed, so that the spring damping rod assembly 9 is compressed, so that the triangular protrusion 801 is disengaged from the inner groove hole of the inner tooth disk 702, and then the knob 1 701 is rotated, and the connecting rod 3 starts to be rotated and adjusted through the transmission of the rotating rod 1 7. After adjusting to the required position, the limit rod 8 is released, the spring damping rod assembly 9 rebounds, and pushes the triangular protrusion 801 to reinsert into the inner groove hole of the inner tooth disk 702 to complete the initial limit. After that, the limit plate 10 is pulled again to slide along the limit groove 1031 until it contacts the limit rod 8 to achieve secondary limit. Next, the knob 2 16 is rotated to The meshing transmission drives the rotating rod 2 12 and the gear 2 14 to rotate. The meshing of the gear 2 14 and the gear 1 501 drives the gear 1 501 to rotate, thereby driving the wiring hook 5 to rotate to a suitable angle. After hanging the wiring hook 5 on the wire, the staff holds the rubber hand grip 102 with one hand and rotates the handle 201 with the other hand. The rotation of the rotating handle 201 drives the insulating screw 2 to rotate, and the insulating screw 2 further drives the metal hose 20 to rotate. The rotation of the metal hose 20 drives the outer screw 17 to rotate. Through the threaded connection between the outer screw 17 and the inner screw 18, the inner screw 18 moves horizontally along the axis of the outer screw 17, pushing the clamping block 19 to move toward the wiring hook 5 until the wire is firmly clamped between the clamping block 19 and the wiring hook 5.
