[0033] Specifically, the open end of the U-shaped ring 5 is connected to the lower left side of the bracket 6. When the device is hooked on the wire and the drone leaves the device, the claw rod 2 will slide vertically downward due to the action of gravity, and the lower end of the claw rod 2 will enter the ring of the U-shaped ring 5. At this time, the U-shaped ring 5 and the claw rod 2 form a closed loop to prevent the wire from escaping.

[0034] Furthermore, the lock tongue mechanism 7 includes a lock cylinder 701, a lock tongue 703, a spring 704 and a lock tongue frame 702. The lock cylinder 701 is embedded in the middle of the lower end of the bracket 6. The lock tongue frame 702 is arranged on the outer periphery of the lock cylinder 701. The lock tongue 703 is slidably nested on the lock tongue frame 702, and one end passes through the radial outer periphery of the lock cylinder 701. The spring 704 is sleeved on the lock tongue 703 to drive the lock tongue 703 to extend and retract along the radial direction of the lock cylinder 701 to lock the heavy hammer lock release mechanism 8.

[0035] Specifically, the lock bolt mechanism 7 is inserted into the lower end of the bracket 6, the upper end of the lock cylinder 701 is a cylinder with an inner circle and an outer square, and the lower end is a cylinder, the outer circumference of the cylinder is larger than the outer circumference of the cylinder, and the upper end of the cylinder has a through hole for the traction rope to enter and exit. The lock cylinder 701 is fixed in the bracket 6 by bolts, the outer circumference of the lock cylinder 701 is connected to a pair of opposite lock bolt frames 702, one end of the lock bolt 703 is sleeved in the lock bolt frame 702, a pair of relatively through lock bolt holes are opened in the radial direction of the outer circumference of the lock cylinder 701, and the other end of the lock bolt 703 passes through the lock bolt hole and extends into the outer circumference of the heavy hammer lock release mechanism 8 to lock the heavy hammer lock release mechanism 8, and the spring 704 is respectively sleeved on the lock bolt 703 to provide elastic force for the lock bolt 703.

[0036] Furthermore, the weight locking and releasing mechanism 8 includes a guide cone head 801, an unlocking cone ring 802, a weight 803 and a traction rope. The guide cone head 801, the unlocking cone ring 802 and the weight 803 are connected in sequence up and down. A traction rope guide rod is provided on the bracket 6 located above the weight locking and releasing mechanism 8. One end of the traction rope passes around the traction rope guide rod and extends out of the bracket 6. The other end of the traction rope is passed through the guide cone head 801 to form a knot.

[0037] Specifically, the guide cone head 801, the unlocking cone ring 802 and the weight 803 are threadedly connected in sequence, the lower end of the weight 803 is a cone structure, the outer peripheral surface of the unlocking cone ring 802 is an inverted cone ring surface, and the axial directions of the guide cone head 801, the unlocking cone ring 802 and the weight 803 are provided with through holes for the guide traction rope or the grounding wire to pass through. At least one pair of spaced traction rope guide rods are arranged above the lock cylinder 701, and the traction rope guide rods are fixed in the bracket 6 for guiding the traction rope connected to the weight 803. The traction rope is inserted from the opening on the rear side of the bracket 6, and is successively passed through the traction rope guide rods to the lock cylinder 701, and is inserted from the through hole on the guide cone head 801, and the traction rope is knotted inside the guide cone head 801 to form a knot to prevent the traction rope from coming out of the guide cone head 801.

[0038] When the switching weight 803 and the grounding wire need to be pulled by a traction rope, the traction rope always moves between the traction rope guide rods and does not get stuck in the gap of the bracket 6.

[0039] In the present invention, as a preference, the traction rope guide rods include two pairs, and each pair of traction rope guide rods are arranged at intervals to guide the traction rope from the vertical direction to the horizontal direction in sequence and then extend out of the bracket 6.

[0040] In order to pull the grounding wire, it is necessary to lower the weight 803 and replace it with a grounding wire connecting plate. The grounding wire is connected to the grounding wire connecting plate. An external thread is provided on the upper outer periphery of the weight 803, and an internal thread is provided on the lower inner periphery of the unlocking cone ring 802.

When the traction rope is pulled up, the conical surface of the guide cone head 801 can push open the locking tongue 703 so that the locking tongue 703 is stuck in the lower part of the unlocking cone ring 802 to fix the weight 803. When the unlocking cone ring 802 is pulled down by the traction rope, the locking tongue 703 can be pushed open so that the weight 803, the unlocking cone ring 802 and the guide cone head 801 move down and disengage from the locking tongue mechanism 7.

[0042] Furthermore, a hook claw block 9 is provided at the front upper end of the bracket 6, and the hook claw rod 2 is slidably nested in the hook claw block 9.

The diameter of the flange 201 is larger than the outer diameter of the hook claw rod 2, and the flange 201 is used to clamp the hook claw rod 2 itself on the hook claw block 9, so as to prevent the hook claw 1 from being supported on the bracket 6 and limit the downward movement of the hook claw 1, so as to facilitate the installation and removal of the soft frame on the hook claw 1 and prevent the hook claw 1 from falling too low.

[0044] Furthermore, the angle between the wire guide rod 3 and the lower end of the hook rod 2 is 70-80°, preferably 75°.

[0045] Specifically, in order to facilitate the upper pressing tongue 401 and the lower pressing tongue 402 to quickly hook up the wire, a wire guide rod 3 is arranged in the opening direction of the wire of the upper pressing tongue 401 and the lower pressing tongue 402. When in use, the wire guide rod 3 is first placed on the wire, and then the drone is translated to move the openings of the upper pressing tongue 401 and the lower pressing tongue 402 to the wire, and the wire is stuck in the gap between the upper pressing tongue 401 and the lower pressing tongue 402. The wire guide rod 3 is a U-shaped ring, the open end is fixed to the upper left end of the bracket 6 with screws, and its length is about 150mm, and the closed end is tilted downward toward the outside of the bracket, and the end of the closed end is tilted to facilitate the entry of the wire.

[0046] Furthermore, a battery assembly is disposed in the bracket 6 , and the battery assembly is electrically connected to the electric telescopic assembly 403 .

[0047] Specifically, a battery compartment 10 is provided in the middle of the bracket 6, and the battery compartment 10 is located between the lock tongue mechanism 7 and the wire hanging mechanism 4, and the battery compartment 10 is used to store the battery assembly. The electric telescopic assembly 403 is powered by the battery assembly. The traction rope guide rod is arranged in the bracket 6 between the lock tongue mechanism 7 and the battery compartment 10, and the traction rope passes through the rear side of the opening of the bracket 6 between the lock tongue mechanism 7 and the battery compartment 10.

[0048] Furthermore, the bracket 6 includes a pair of support plates 601 , the pair of support plates 601 are connected with relative spacing, and the wire hanging mechanism 4 , the locking tongue mechanism 7 , the hook claw block 9 and the battery assembly are embedded between the pair of support plates 601 .

[0049] Specifically, the center of the lower end of the support plate 601 is slotted, the lock cylinder 701 is embedded in the slot, and the outer peripheral surface of the lock cylinder 701 is flush with the outer side surface of the support plate 601. In the utility model, the support plate 601 is an aluminum alloy plate with a thickness of 1 mm, and the support plate 601 is a hook-shaped structure. A pair of support plates 601 are connected at intervals by bolts.

[0050] The utility model provides a ground wire hanging and removing device for unmanned aerial vehicles, and the working process is as follows:

[0051] The assembly and disassembly soft frame is installed on the drone, and the hook 1 is connected to the assembly and disassembly soft frame. The traction rope is inserted from the opening below the battery compartment 10, and is successively inserted between the traction rope guide rods, and then is inserted into the lock cylinder 701 and inserted from the through hole on the guide cone head 801. The traction rope is knotted inside the guide cone head 801. The other end of the traction rope is held by the ground operator. As the drone rises, the traction rope is released. At this time, the electric telescopic assembly 403 is in an extended state, and the upper pressing tongue 401 and the lower pressing tongue 402 are separated.

[0052] The UAV takes off and lifts the device. At this time, because the claw rod 2 is movable in the claw plug block 9, under the action of gravity, the tail of the claw rod 2 is stuck in the bottom of the claw plug block 9, and there is no closed loop between the U-shaped ring 5, the claw rod 2 and the bracket 6. As the UAV reaches the working position, the wire guide rod 3 is placed on the wire, and then the UAV is translated to move the gap between the upper pressure tongue 401 and the lower pressure tongue 402 to the wire, and the wire is hung in the gap.

[0053] When the device is hooked on the wire and the drone leaves the device, the hook rod 2 will slide vertically downward due to gravity, and the lower end of the hook rod 2 will enter the U-shaped ring 5. At this time, the U-shaped ring 5 and the hook rod 2 form a closed ring when viewed from the side, which is used to prevent the wire from falling out.

[0054] The ground personnel pull the traction rope connected to the guide cone head 801 to lift the guide cone head 801. At this time, the unlocking cone ring 802 is connected to the lower part of the guide cone head 801 until the unlocking cone ring 802 pushes open the two locking tongues 703. The position of the unlocking cone ring 802 is lifted above the locking tongues 703. Since the unlocking cone ring 802 is an inverted cone, it is sleeved on the tail of the guide cone head 801 and can slide up and down in the vertical direction. Before falling from the highest point, the unlocking cone ring 802 is supported above the two locking tongues 703. Under the action of gravity, the unlocking cone ring 802 and the guide cone head 801 fit tightly and will not separate. At this time, the traction rope is loosened, and the unlocking cone ring 802 pushes the two locking tongues 703 apart, causing the unlocking cone ring 802 and the guide cone head 801 to fall at the same time. The two come out from the locking tongues 703 one after another and are not supported by the locking tongues 703, so that they are lowered to the ground along the traction rope. On the ground, the heavy hammer 803 is twisted off from the tail of the guide cone head 801 and replaced with a grounding wire connecting plate, and the grounding wire is connected to the grounding wire connecting plate.

[0055] When the ground personnel lift the guide cone head 801 with the replaced grounding wire into the locking tongue mechanism 7, since the guide cone head 801 is vertical at this time, the unlocking cone ring 802 slides away from the end of the guide cone head 801 under the action of gravity. At this time, when the guide cone head 801 is lifted upward again under the action of the traction rope, it pushes open the locking tongue 703, but the unlocking cone ring 802 does not push open the locking tongue 703. At this time, the traction rope is loosened, and the guide cone head 801 will not work together with the unlocking cone ring 802 to lower the guide cone head 801, so that the guide cone head 801 is stuck on the locking tongue 703 and does not fall off.

[0056] After the grounding wire is installed, the ground personnel use the remote control to control the electric telescopic assembly 403 to retract, and the upper pressing tongue 401 and the lower pressing tongue 402 to shrink and clamp the wire.

[0057] When the operation is completed and the grounding wire is removed, the ground personnel pull the traction rope connected to the guide cone head 801 to lift the guide cone head 801. At this time, the unlocking cone ring 802 is inserted from the bottom of the guide cone head 801, and the grounding wire connecting plate is connected to the grounding wire. The grounding wire connecting plate is connected to the grounding wire. The grounding wire is lowered using the same principle as lowering the weight 803, and then the grounding wire is removed from the grounding wire connecting plate, and then the grounding wire connecting plate is removed from the guide cone head 801 and the weight 803 is installed on the tail of the guide cone head 801; then the traction rope is pulled, and the weight 803 is pulled up into the locking tongue mechanism 7 and locked using the same principle as locking the grounding wire.

[0058] After the ground wire is removed, the ground personnel use the remote control to control the electric telescopic assembly 403 to extend, the upper pressing tongue 401 and the lower pressing tongue 402 to open, and the wire is released.

[0059] The drone lifts the device again. During the lifting, the hook claw rod 2 can slide in the vertical direction in the hook claw plug block 9, so the hook claw rod 2 is pulled out, but it will not fall out of the hook claw plug block 9. At this time, the closed loop composed of the U-shaped ring 5, the hook claw rod 2 and the bracket 6 is opened, and the hanging and removing grounding wire device can leave the wire without being blocked by the closed loop composed of the U-shaped ring 5, the hook claw rod 2 and the bracket 6. The drone lowers the device to the ground to complete the operation.
