DETAILED DESCRIPTION

[0046] 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.

[0047] See also Figure 1-8 The present invention provides a technical solution: a spacer device for installing power on a drone, comprising:

[0048] Three sets of fastening units 1, used for fastening three wires;

[0049] A plurality of connecting devices 2 are arranged between two adjacent groups of the fastening units 1, and are used to form a triangular support structure with the three groups of the fastening units 1. The three groups of the fastening units 1 are arranged in an isosceles triangle shape, and the two groups of the fastening units 1 at the lower end of the isosceles triangle are symmetrically arranged.

[0050] Wherein, the fastening unit 1 comprises:

[0051] A fastening top block 11 is connected to the connecting unit 3, one side of the fastening top block 11 is provided with three wire inlets 12, and a V-shaped groove 13 is provided at the lower end of the fastening top block 11;

[0052] A pressing block 14 is slidably disposed in the fastening top block 11;

[0053] A threaded screw 15 is threadedly connected to the fastening top block 11. One end of the threaded screw 15 is rotatably connected to the pressing block 14, and the other end is detachably sleeved with a connecting unit 3. The connecting unit 3 is used to connect to the drone body and drive the threaded screw 15 to rotate.

[0054] After the three wires enter the fastening top block 11 from the three wire inlet 12, the threaded screw 15 is driven to rotate through the connecting unit 3, so that the pressing block 14 will move downward, thereby driving the three wires to be pressed against the V-shaped groove 13, thereby realizing three-point pressing and fixing. At the same time, in order to prevent the three wires from detaching from the pressing block 14 when being pressed downward, the pressing block 14 will be arranged in an arc shape, and rubber pads will be arranged on the surfaces of the pressing block 14 and the V-shaped groove 13 to protect the three wires from wear when being pressed and fixed. Among them, the end of the threaded screw 15 and the pressing block 14 are arranged to rotate, so that when the threaded screw 15 rotates and drives the pressing block 14 to move downward, it will not drive the pressing block 14 to rotate.

[0055] In addition, the connection unit 3 includes:

[0056] A cross clamping bar 31 is fixed to the end of the threaded screw 15 away from the pressing block 14;

[0057] A sleeve 32 is detachably sleeved on the cross clamping strip 31, wherein a stopper strip 33 for cooperating with the cross clamping strip 31 is arranged in the sleeve 32;

[0058] A rotating motor 34 is connected to the sleeve 32 and is used to drive the sleeve 32 to rotate. The rotating motor 34 is connected to the drone body;

[0059] The bell mouth 35 is arranged at the mouth of the sleeve 32. In actual use, the sleeve 32 is inserted into the cross clamping bar 31 and is connected to the sleeve 32 by threads to achieve a detachable connection.

[0060] At the same time, the connecting device 2 includes:

[0061] Two insulating rods 21, the ends of the two insulating rods 21 being remote from each other and being hinged to the two adjacent fastening top blocks 11, and the ends of the two insulating rods 21 being close to each other are clamped by a clamping piece 22;

[0062] The clamping member 22 includes an upper clamping plate 221 and a lower clamping plate 222. The upper clamping plate 221 and the lower clamping plate 222 are provided with a clamping groove for the insulating rod 21 to be clamped in. The upper clamping plate 221 and the lower clamping plate 222 are fastened by bolts.

[0063] In actual use, the total length between the two insulating rods 21 can be adjusted according to the actual spacing between the three wires, and fastened by the clamping piece 22. In the specific setting, the inside of the card slot will be set to be corrugated, so as to increase the friction after the insulating rod 21 is fastened, thereby increasing the clamping effect. At the same time, when the bolts are used to fasten the upper clamping plate 221 and the lower clamping plate 222, two connected threaded holes are provided on the outer, middle and inner sides of the upper clamping plate 221 and the lower clamping plate 222 to facilitate the insertion and fastening of the bolts.

[0064] A guide rod 16 is provided between the fastening top block 11 and the pressing block 14, so that the three-phase electric wires can enter the fastening top block 11 from the guide rod 16 through the three-phase electric wire inlet 12;

[0065] A first ring 17 is disposed on the guide rod 16;

[0066] The second ring 18 is arranged on the sleeve 32, and the first ring 17 and the second ring 18 are connected by a connecting rope;

[0067] During actual assembly, one end of the guide rod 16 will be inserted between the upper end of the fastening top block 11 and the pressing block 14, and the height of the pressing block 14 will be adjusted by the threaded screw 15, so that the guide rod 16 will be clamped between the fastening top block 11 and the pressing block 14. During actual operation, the sleeve 32 connected to the drone body will be connected to the fastening unit 1 through the first ring 17 and the second ring 18 through the connecting rope, and the drone body will enter the three-wire position from under the three-wire, and then the fastening unit 1 at the upper end will be installed first to control the flight position of the drone, and then the three-wire conductor at the upper end will be moved from the guide rod 16 into the When the sleeve 32 is inserted into the fastening top block 11, when it is on the ground, the sleeve 32 has been docked with the cross clip 31 on the upper fastening unit 1. When the rotating motor 34 drives the sleeve 32 to rotate, the thread is driven to move, so that the three-wire conductor at this location will be clamped and fixed. At the same time, since the guide rod 16 at this location loses its clamping and is clamped, it will be separated from the fastening unit 1, and then the drone body will drive the sleeve 32 to move to the other two three-wire conductors in turn, and dock with the cross clip 31 through the bell mouth 35. Repeat the above operations, install the other two three-wire conductors in turn, and finally the three guide rods 16 are all lowered to the ground as the drone body descends.

[0068] In addition, the sleeve 32 is also provided with an auxiliary unit 4 for assisting the three-way guide to enter the fastening top block 11 from the guide rod 16;

[0069] The auxiliary unit 4 comprises:

[0070] A third collar 41 is mounted on the sleeve 32;

[0071] A tripping device, arranged on the third ring 41;

[0072] The three groups of traction ropes 42 are provided with rope buckles 43 at one end, and the rope buckles 43 are sleeved on the release device.

[0073] Finally, the tripping device comprises:

[0074] A bracket 44 is fixedly mounted on the third ring 41;

[0075] A slide plate 45, on which three release baffles 46 are sequentially arranged at intervals, each of which is slidably arranged on the bracket 44 along the axial direction of the sleeve 32, and the rope buckle 43 is sleeved on the bracket 44 in two adjacent release baffles 46 and blocked by the release baffles 46;

[0076] The power unit 47 is disposed on the bracket 44 and is used to drive the slide plate 45 to slide back and forth along the axis direction of the sleeve 32, so that each release baffle 46 and each rope buckle 43 are separated from the bracket 44 from one end of the bracket 44 in sequence;

[0077] Before the UAV body carrying the fastening unit 1 flies to the three-way electric wire, the traction rope 42 is firstly set on the three-way electric wire through the release device in cooperation with the UAV body, so as to pull the traction rope 42 from the ground, thereby pulling the three-way electric wire in the air, so that the three-way electric wire can better enter the fastening top block 11 from the guide rod 16;

[0078] First, one end of the three sets of traction ropes 42 with rope buckles 43 is respectively mounted on the bracket 44 located in the release baffle 46, and then, Figure 6 As shown, the drone body will drive the traction rope 42 to move above the three-wire A and to the side of the three-wire B and C. At this time, the power unit 47 works to drive the sliding plate 45 to move outward on the bracket 44. When the first release baffle 46 is detached from the bracket 44, the rope buckle 43 at the end of the traction rope 42 will also be detached from the bracket 44, so that the rope buckle 43 will fall to the ground. A counterweight block can be set at the end of the traction rope 42 to drive the traction rope 42 to fall with the three-wire A as a fulcrum. Then the drone body continues to rise to above the three-wire B, and then continues to rise until the lower end of the traction rope 42 is higher than the three-wire A and passes over the three-wire. Then repeat the above operation to avoid the influence of the traction rope 42 and the previous traction rope 42. Finally, the drone body drives the installation of the last traction rope 42. As described above, the traction line is put on the three-wire C to complete the traction rope 42 of the entire auxiliary unit 4.

[0079] When the fastening unit 1 is installed, the drone drives the fastening unit 1 to move toward the three wires. When it moves under the three wires, the manual operation from the ground will be as follows: Figure 7As shown, the three guides A and C are pulled apart to both sides by the traction rope 42, so that the main body of the drone drives the fastening unit 1 to fly to the bottom of the three wires B, and the drone is continued to be controlled to fly to the guide rod 16 close to the three wires B, and then the traction rope 42 is pulled to make the three wires B slide into the fastening top block 11 and be fixed, and then the three wires A and C are installed into the fastening top block 11 in turn, thereby completing the live installation of the entire spacing device.
