[0001] The invention relates to the technical field of electric wire maintenance, in particular to a double-clamp ground grounding wire device. Background Art

[0002] In recent years, with the development of economy and the improvement of people's living standards, higher requirements have been put forward for the reliability of power supply. In order to ensure that users do not have power outages, it is necessary to increase the maintenance of power transmission and distribution lines. During the maintenance process, the power transmission and distribution lines need to be grounded.

[0003] However, in the process of maintaining the grounding wire of the power transmission and distribution lines in the existing technology, workers need to climb the tower to install the grounding wire, which has a high risk of falling from a height, causing personal injury accidents, and is time-consuming and labor-intensive to install and remove. In addition, the grounding wire operating rod is long, and storage and transportation take up a lot of space. When the grounding wire is disassembled and installed, it is necessary to climb the tower twice, which greatly reduces the maintenance work efficiency.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0005] The purpose of the present invention is to provide a double-clamp ground grounding wire device to solve the problems of high risk of falling and low maintenance work efficiency in the process of maintaining grounding wires of power grid transmission and distribution lines in the prior art proposed in the above background technology.

[0011] Furthermore, the lifting unit comprises:

[0012] An extension rod, fixedly connected to the middle of the upper end of the wiring rod;

[0013] A lifting block is fixedly connected to the middle of the upper end of the extension rod, and inclined surfaces are provided on both sides of the lifting block, which are used to guide the wires into the locking assembly along the inclined surfaces when the side of the lifting block contacts the wires;

[0014] A rotating rod, rotatably connected to one end of the lifting block;

[0015] The first pull line has one end connected to the rotating rod and the other end connected to the drone, and is used to drive the extension rod to lift through the drone.

[0016] Furthermore, the locking assembly comprises:

[0017] A bent rod fixedly connected to the upper end of the lifting block;

[0018] An arc-shaped groove is provided on the inner side of the top of the curved rod and is used to accommodate the wires;

[0026] A baffle, fixedly connected to one end of the telescopic rod opposite to the limit block, the baffle being slidably connected to the retreat groove;

[0027] The return spring is sleeved on the outside of the telescopic rod and located between the U-shaped frame and the baffle plate, and is used for driving the baffle plate to return to its original position.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention connects one end of the first pull wire to the drone, and a staff member standing on the ground controls the drone to fly upward and bypass the high electric wires through a remote control. The drone drives the rotating rod to lift upward through the first pull wire, and the rotating rod drives the first ground wire and the second ground wire to lift upward synchronously through the extension rod under the action of the connecting rod. At the same time, the extension rod drives the lifting block to one side of the electric wire, and the lifting block drives the bending rod to lift upward until the height of the bending rod is higher than the height of the electric wire. At this time, the drone is controlled to fly in the direction perpendicular to the extension of the electric wire, so that the electric wire transitions to the arc groove along the inclined surface of the side of the lifting block through the inner side of the bending rod. By arranging bending rods on both sides of the upper end of the lifting block, it is ensured that when the lifting block is lifted to the height of the electric wire, the side of the lifting block corresponding to the electric wire can transition to the arc groove along the inclined surface of the lifting block, and there is no need to make a secondary adjustment to the direction of the lifting block.

[0036] 2. The present invention remotely starts the electric cylinder through a remote controller, and the electric cylinder drives the top column to move downward, so that the second pull wire is relaxed. At this time, the return spring that was originally in a compressed state drives the baffle to move along the retreat groove to the position directly below the arc groove under the action of the contact force between the U-shaped frame, so that the wires in the arc groove are locked, and the grounding work of the wires through the first ground wire and the second ground wire is completed. The entire grounding work does not require manual climbing of the tower to work at high altitudes, and the operation is safe and the work efficiency is high.

[0037] 3. The present invention remotely starts the electric cylinder through a remote control, and the electric cylinder drives the top column to move upward, and the top column drives the telescopic rod to move through the second pull wire, and the telescopic rod drives the baffle to move along the retreat groove and gradually compresses the reset spring, so that the baffle moves out from the wire under the arc groove. At this time, the staff pulls the second ground wire downward from the ground, and the second ground wire drives the extension rod to move downward through the wiring rod, and the extension rod drives the bending rod to move downward through the lifting block, so that the wire in the arc groove is separated from the arc groove. Subsequently, the drone is controlled to drive the first pull wire to gradually move downward to the ground, and the disassembly of the ground wire is completed. There is no need for the staff to climb the tower twice, which greatly improves the work efficiency of wire maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The wire fixing mechanism 217 is disposed inside the retreat groove 2131 and is used to lock the wire 100 in the arc groove 212 .

[0061] Furthermore, the line fixing mechanism 217 includes:

[0062] A U-shaped frame 2171, fixedly connected to one side of the fixing block 213 and located below the bracket 214;

[0063] The telescopic rod 2172 is slidably inserted into the U-shaped frame 2171;

[0064] A limit block 2173 connected to one end of the telescopic rod 2172, used to limit the movement of the telescopic rod (2172), and one end of the limit block 2173 relative to the telescopic rod 2172 is connected to a second pull wire 21731;

[0066] The return spring 2175 is sleeved on the outside of the telescopic rod 2172 and located between the U-shaped frame 2171 and the baffle 2174, and is used to drive the baffle 2174 to return to its original position.

[0067] The lower end of the bracket 214 is provided with a guide block 216 for guiding the second pull wire 21731;

[0068] One end of the bracket 214 is provided with a second guide roller 215 for guiding the second pull wire 21731;

[0070] In addition, if Figure 3 As shown, the lifting assembly 22 includes:

[0071] The electric cylinder 221 is installed on the upper end of the lifting block 11;

[0072] The top column 222 is connected to the driving end of the electric cylinder 221 , and one end of the second pull wire 21731 is connected to the outer side of the top column 222 .

[0073] It should be noted that: Figure 1As shown, in the specific implementation process of the present invention, when it is necessary to connect the first ground wire 16 and the second ground wire 17 to the high wire 100 from the ground, one end of the first pull wire 15 is connected to the drone, and the staff standing on the ground controls the drone to fly upward and bypass the high wire 100 through the remote control. The drone drives the rotating rod 14 to rise upward through the first pull wire 15, and the rotating rod 14 drives the first ground wire 16 and the second ground wire 17 to rise synchronously upward through the extension rod 12 under the action of the connection rod 13. At the same time, the extension rod 12 drives the lifting block 11 to rise to one side of the wire 100, and the lifting block 11 carries The movable bending rod 211 is lifted upward until the height of the bending rod 211 is higher than the height of the wire 100. At this time, the drone is controlled to fly in the direction perpendicular to the extension of the wire 100, so that the wire 100 transitions to the arc groove 212 along the inclined surface of the side of the lifting block 11 through the inner side of the bending rod 211. By arranging the bending rods 211 at both sides of the upper end of the lifting block 11, it is ensured that when the lifting block 11 is lifted to the height of the wire 100, the side of the lifting block 11 corresponding to the wire 100 can transition to the arc groove 212 along the inclined surface of the lifting block 11, and there is no need to adjust the direction of the lifting block 11 for a second time.

[0074] like Figure 2-4 As shown, after the wire 100 transitions to the arc groove 212, the electric cylinder 221 can be remotely started by the remote control, and the electric cylinder 221 drives the top column 222 to move downward, so that the second pull wire 21731 is relaxed. At this time, the return spring 2175, which was originally in a compressed state, drives the baffle 2174 to move along the retreat groove 2131 to the position directly below the arc groove 212 under the action of the pressing force between the return spring 2175 and the U-shaped frame 2171, so that the wire 100 in the arc groove 212 is locked, and the grounding work of the wire 100 through the first ground wire 16 and the second ground wire 17 is completed. The entire grounding work does not require manual work at a height by climbing the tower, and the operation is safe and the work efficiency is high.

[0075] like Figure 1 , Figure 4-5As shown, when the first ground wire 16 and the second ground wire 17 need to be removed from the height of the wire 100, the electric cylinder 221 is remotely started through the remote control, and the electric cylinder 221 drives the top column 222 to move upward, and the top column 222 drives the telescopic rod 2172 to move through the second pull wire 21731, and the telescopic rod 2172 drives the baffle 2174 to move along the retreat groove 2131 and gradually compresses the reset spring 2175, so that the baffle 2174 moves out from the wire 100 located below the arc groove 212. At this time, the staff pulls the second ground wire 17 downward from the ground, and the second ground wire 17 drives the extension rod 12 to move downward through the wiring rod 13, and the extension rod 12 drives the bending rod 211 to move downward through the lifting block 11, so that the wire 100 located in the arc groove 212 is separated from the arc groove 212. Subsequently, the drone is controlled to drive the first pull wire 15 to gradually move downward to the ground, and the disassembly of the ground wire is completed. There is no need for the staff to climb the tower twice, which greatly improves the work efficiency of the maintenance of the wire 100.
