Description

Technical Field

[0001] The present invention relates to the field of grounding wire hanging and removing, and in particular to a grounding wire device based on unmanned aerial vehicle hanging and removing and a grounding method thereof. Background Art

[0002] In order to ensure the personal safety of construction workers who are performing power outage maintenance on transmission lines, grounding wires must be installed at all ends of the work area and at branch lines that may supply power to the power outage maintenance transmission lines. The existing 500kV transmission line grounding line installation and removal usually adopts the throwing and hanging method, which requires workers to climb to the crossarm exit, hold the insulating rope and lower the opened wire clamp, use gravity to hit the wire so that the wire clamp fastens the wire, and pull the insulating rope hard when removing it so that the wire breaks free from the wire clamp and detaches.

[0003] Although this method is commonly used, it also has several disadvantages: First, it requires construction workers to climb the tower to operate. The higher the voltage level, the higher the tower. Construction workers need to expend great physical strength in the process of climbing up and down the tower, and there is a risk of falling from a height. Second, the transmission line towers are often located outdoors on high mountains. Operators have to climb mountains and wade through water to reach the bottom of the tower, which takes a long time, which invisibly shortens the power outage maintenance operation time and affects the work efficiency of the transmission maintenance operation.

[0022] When using the device, first open the grounding terminal clamp 3 and the wire end clamp 4, hang the grounding terminal clamp 3 and the wire end clamp 4 on the left hanging plate 21 and the right hanging plate 22 respectively, and use the drone 1 to drive the takeoff to change the position; first fly to the vicinity of the iron tower to complete the connection of the grounding terminal clamp 3, then fly to the vicinity of the wire end clamp 4 operation, complete the hanging of the wire end clamp 4, after the inspection is completed, the drone 1 is operated to take off, remove the grounding terminal clamp 3 and the wire end clamp 4, complete the dismantling, and then use the drone 1 to fly to other operation areas to continue the operation, thereby improving the operation efficiency.

[0023] like Figure 3 and Figure 4As shown, as a preferred embodiment, the grounding terminal fixture 3 includes a first hanging iron frame 31, a round hook 32, an embedded spring 33, a first fixing pile 34, a second fixing pile 35, a third fixing pile 36, a baffle 37, a clamping plate 38, a protruding module 39 and a second spring 310; the first hanging iron frame 31 is hung on the left hanging plate 21; the round hook 32 is vertically arranged, and the right end is lower than the left end, and is connected to the lower end of the first hanging iron frame 31 through a hanging shaft, and the left bottom end of the round hook 32 is provided with a first connecting hole 321; the first fixing pile 34 is arranged on the left part of the round hook 32, and the second fixing pile 35 is arranged on the left part of the round hook 32. It is placed at the upper right end of the circular hook 32, and the third fixing pile 36 is set at the lower right end of the circular hook 32; after the left end of the embedded spring 33 bypasses the lower end of the first fixing pile 34, the right end is wrapped around the upper end of the second fixing pile 35; the baffle 37 is vertically set at the right end of the embedded spring 33; the right part of the clamping plate 38 is hinged to the right part of the circular hook 32, and the left end is provided with a second connecting hole 381 matching the first connecting hole 321; the protruding module 39 is set at the right end of the clamping plate 38; the upper end of the second spring 310 is connected to the right end of the clamping plate 38, located on the left side of the protruding module 39, and the lower end is connected to the third fixing pile 36. In this embodiment, the grounding terminal clamp 3 is opened in the initial state, the first hanging iron frame 31 is fixed on the round hook 32 through the hanging shaft, the round hook 32 is welded by two layers of aluminum alloy, and has an embedded baffle 37, one end of the baffle 37 is connected to the embedded spring 33, and the other end is placed on the second fixing pile 35; the baffle 37 is fixed on the inner hollow of the round hook 32 through the embedded spring 33, the first fixing pile 34 and the second fixing pile 35. If there is resistance, the baffle 37 can move up and down briefly on the inner hollow of the round hook 32, and the front end of the baffle 37 is in a vertical folded state. When the clamp 38 is opened, it can be used to resist the protruding module 39 located at the front end of the clamp 38 at this time, so that the clamp 38 is embedded in the round hook 32 and remains motionless. The clamp 38 can rotate in the round hook 32 through bolts, and the width of the clamp 38 is consistent with the width of the hollow tube of the round hook 32. When the clamping plate 38 is retracted, the clamping plate 38 can be completely embedded in the round hook 32. The gasket of the clamping plate 38 has a triangular protrusion module 39. The distance from the bottom end of the protrusion module 39 to the bolt is consistent with the distance from the front end of the baffle 37 to the bolt, so that when the clamping plate 38 is opened, the protrusion module 39 can lift the front end of the baffle 37. After the protrusion module 39 passes, the baffle 37 then drops to clamp the clamping plate 38 and tightens it under the force of the embedded spring 33. At this time, the grounding terminal clamp 3 is opened, and the opening width is slightly larger than the width of the crossarm crossbar.

[0024] like Figure 5 and Figure 6As shown, as a preferred embodiment, the wire end clamp 4 includes a second hanging iron frame 41, a shell 42, a left clamp 43 and a right clamp 44; the second hanging iron frame 41 is hung on the right hanging plate 22; the shell 42 is inverted U-shaped and is arranged at the lower end of the second hanging iron frame 41 through a hanging shaft; the left clamp 43 includes a fourth fixed pile 431, a first movable pile 432, a second movable pile 433, a third spring 434, a first connecting rod 435, a second connecting rod 436, a third connecting rod 437 and a semicircular clamp 438; the fourth fixed pile 431 is arranged at the middle end of the left part of the shell 42; the upper end of the first connecting rod 435 is connected to the hanging The lower end of the shaft is hinged to the first movable pile 432; the upper end of the second connecting rod 436 is hinged to the first movable pile 432, and the lower end is connected to the fourth fixed pile 431; the upper end of the third connecting rod 437 is connected to the fourth fixed pile 431, and the lower end is connected to the second movable pile 433, and the second movable pile 433 is connected to the lower end of the semicircular clamp 438 through the third spring 434; the middle part of the semicircular clamp 438 is rotatably connected to the shell 42; the right clamp 44 and the left clamp 43 have the same structure and are symmetrically arranged on the right side of the left clamp 43, and the semicircular clamp 438 of the left clamp 43 and the semicircular clamp of the right clamp 44 jointly clamp the wire. In this embodiment, when the wire end clamp 4 is used, the second hanging iron frame 41 is fixed to the hanging shaft and moved up and down together. The upper end of the first connecting rod 435 is connected to the lower end of the hanging shaft, and the lower end is hinged to the first movable pile 432; the upper end of the second connecting rod 436 is hinged to the first movable pile 432, and the lower end is connected to the fourth fixed pile 431; the upper end of the third connecting rod 437 is connected to the fourth fixed pile 431, and the lower end is connected to the second movable pile 433.

[0025] like Figure 5 As shown, the fourth fixed pile 431 and the middle part of the semicircular clamp 438 are both connected to the shell 42. When the second hanging iron frame 41 is lifted, the first connecting rod 435 is lifted accordingly, driving the second connecting rod 436 and the third connecting rod 437 to move upward, and the first movable pile 432 and the second movable pile 433 also move with it. At this time, since the third spring 434 connects the second movable pile 433 and the lower end of the semicircular clamp 438, the lower end of the semicircular clamp 438 is pulled to the left; at this time, the right clamp 44 makes the same action to jointly complete the opening of the semicircular clamp 438. The opening width is greater than the diameter of the power outage maintenance wire, which is convenient for the flexible entry of the wire and realizes the clamping of the wire; when closing is required, the downward reverse operation can be performed to achieve closing.

[0026] like Figure 2As shown, as a preferred embodiment, the left hanging plate 21 is V-shaped, and the opening is upward, and the first hanging iron frame 31 is hung at the lowest point of the left hanging plate 21. In this embodiment, the left hanging plate 21 is V-shaped, and when the first hanging iron frame 31 is hung on the left hanging plate 21, it is at the lowest point of the left hanging plate 21, and there is a height difference between the left and right sides. It can be stably hung at the lowest point during the rising and falling process, ensuring the stability of the device.

[0027] like Figure 2 As shown, as a preferred embodiment, the right hanging plate 22 is V-shaped, with the opening facing upward, and the second hanging iron frame 41 is hung at the lowest point of the right hanging plate 22. In this embodiment, the right hanging plate 22 and the left hanging plate 21 have the same structural shape, and can also ensure that the second hanging iron frame 41 is always at the lowest point of the right hanging plate 22 during the rising and falling process, thereby ensuring the stability of the device.

[0028] When in use, the operator opens the clamp of the grounding end clamp in advance, rotates it to the baffle to fix it, completes the opening of the grounding end clamp, and facilitates the entry of the cross-arm tower material. Then the grounding end clamp and the wire end clamp connected to the grounding wire are placed on both sides of the lifting device respectively, and the drone is operated to take off, and the grounding end clamp and the wire end clamp are flown to the vicinity of the tower, and the grounding end clamp is lowered to the cross-arm to fix it in a suitable position. The cross-arm tower material touches the baffle, and the baffle rises slightly. The clamp protrusion module loses its restraint and rotates under the action of the second spring to form a closure, completing the hanging of the grounding end of the grounding wire. The drone flies to the appropriate position of the wire, aligns the position and lowers the wire end clamp, and the wire is fixed by the semicircular clamp to complete the hanging of the wire end of the grounding wire. After the belt maintenance is completed, the drone operator takes off with the lifting device, lifts the wire end fixture to hang the iron frame through the flat plate, and the hanging shaft rises to drive the coupling shaft to rotate, the upper part of the circular half fixture closes, and the lower part opens, completing the separation of the wire and the wire end fixture. The grounding end fixture is separated in the same principle, thus completing the removal of the wire end fixture and the grounding end fixture. The device is simple to operate, highly safe, and time-saving. It only needs to be operated by a ground drone, which can avoid the safety risks of workers on the tower and has high promotion value.
