An ear plate 311 is fixedly connected to one side of the conveyor belt 308, and a first circular arc plate 312 is fixedly connected to the side of the ear plate 311 away from the conveyor belt 308. Connection holes 313 are opened on both sides of the first circular arc plate 312, and the inner walls of the two connection holes 313 are rotatably penetrated with a rotating shaft 314, and the circular arc surface of the rotating shaft 314 is fixedly connected to the second circular arc plate 315, and the circular arc surface of the rotating shaft 314 is sleeved with two coil springs 316. The two ends of the coil spring 316 are fixedly connected to the second arc plate 315 and one side of the inner wall of the connecting hole 313 respectively. When the second arc plate 315 is not subjected to external force, the first arc plate 312 is coaxial with the center of the second arc plate 315. The outer wall of the annular hose 319 is fixedly connected with a plurality of first fixing columns 317 and a plurality of second fixing columns 318. The end of the first fixing column 317 away from the annular hose 319 is fixedly connected to the inner wall of the first arc plate 312, and the end of the second fixing column 318 away from the annular hose 319 is fixedly connected to the inner wall of the second arc plate 315.

[0045] When it is necessary to spray protective coating on the repaired part of the overhead ground wire, start the hydraulic cylinder 303 to drive the support frame 304, the support frame 304 drives the connecting frame 305, and the connecting frame 305 drives the first arc plate 312 to move in the direction close to the overhead ground wire. When the first arc plate 312 drives the two second arc plates 315 to abut against the overhead ground wire, the overhead ground wire will squeeze the two second arc plates 315, so that the two second arc plates 315 rotate along the inner wall of the connecting hole 313, so that the two second arc plates 315 are opened, so that the overhead ground wire can enter the space formed by the first arc plate 312 and the two second arc plates 315, and the overhead ground wire can be located inside the annular hose 319, so that the multiple nozzles 320 can be aimed at the overhead ground wire, and then start The conveying pump in the storage box 301 is driven to allow the protective coating to flow into the nozzle 320 along the storage box 301, the bellows 321, and the annular hose 319, so that the nozzle 320 sprays the protective coating to the repair position of the overhead ground wire. At the same time, the servo motor 310 is started to drive the driving wheel 307 to rotate, so that the conveyor belt 308 rotates in the limit of the driving wheel 307 and the driven wheel 306, and the conveyor belt 308 drives the ear plate 311, and the ear plate 311 drives the first circular plate 312 and the second circular plate 315 to rise or fall, and the first circular plate 312 and the second circular plate 315 drive the annular hose 319 and the nozzle 320 to rise or fall, so that the nozzle 320 can be raised and lowered during the process of spraying the coating, so that the protective coating can be evenly sprayed on the repair position of the overhead ground wire.

[0046] The spray repair mechanism 300 also includes a screw rod 322, which is rotatably connected to the inner wall of the connecting frame 305, and the arc surface of the screw rod 322 is provided with a bidirectional thread. The lower surface of the connecting frame 305 is fixedly connected to a drive motor 323, and the output end of the drive motor 323 is fixedly connected to the lower end of the screw rod 322. The arc surface of the screw rod 322 is threadedly connected to two drive plates 324, and the surface of the drive plate 324 is provided with a rectangular hole 326. The bellows 321 is slidably penetrated in the inner wall of one of the rectangular holes 326. The drive plate 324 is fixedly connected to a fixed seat 327 on the side away from the support frame 304. The inner wall of the fixed seat 327 is rotatably penetrated with a threaded rod 328, and the arc surface of the threaded rod 328 is provided with a bidirectional thread. The fixed seat 327 A motor 329 is fixedly connected to one side of the motor 329, and the output end of the motor 329 is fixedly connected to one end of the threaded rod 328. The arc surface of the threaded rod 328 is threadedly connected to two connecting plates 330. A guide rod 331 is slidably passed through one side of the two connecting plates 330. The guide rod 331 is fixedly connected to the fixed seat 327. A clamping plate 332 is fixedly connected to the side of the connecting plate 330 away from the fixed seat 327. The two clamping plates 332 are centrally symmetrical, and the center of symmetry of the two clamping plates 332 is coaxial with the center of the first circular arc plate 312. By setting the above structure, before spraying the protective coating on the repaired part of the overhead ground wire, the clamping plate 332 can be used to clamp the upper and lower parts of the sprayed position, thereby improving the stability of the protective coating spraying process.

[0047] The four clamps 332 are divided into two groups, one group of which has a receiving groove 334 on its upper surface. By opening the receiving groove 334 on one group of the clamps 332, when the nozzle 320 is used to spray the protective coating on the repaired part of the overhead ground wire, the receiving groove 334 can absorb the dripping protective coating, thereby minimizing the amount of coating dripping onto the ground and polluting the surrounding environment.

[0048] The inner wall of the clamping plate 332 is fixedly connected with a rubber pad 333 , and the rubber pad 333 is adapted to the size of the inner wall of the clamping plate 332 . The rubber pad 333 can increase the friction and softness of the inner wall of the clamping plate 332 , thereby improving the limiting effect of the clamping plate 332 on the overhead ground wire.

[0049] A plurality of positioning rods 325 are slidably provided on the surface of the driving plate 324, and the positioning rods 325 are fixedly connected to the inner wall of the connecting frame 305.

[0050] The outer wall of the first arc plate 312 is fixedly connected with a positioning ring 335, and the inner wall of the positioning ring 335 fits the arc surface of the screw rod 322. When the ear plate 311 drives the first arc plate 312 to rise and fall, the positioning ring 335 fixed on the first ear plate 311 will move along the arc surface of the screw rod 322, thereby achieving the effect of improving the stability of the first arc plate 312 during the lifting process.

[0051] The two drone brackets 200 are fixedly connected to a limit plate 336 on one side close to each other, and a limit rod 337 is slidably penetrated through the side of the limit plate 336. One end of the limit rod 337 is fixedly connected to a side of the support frame 304 away from the connecting frame 305. When the hydraulic cylinder 303 drives the support frame 304 and the connecting frame 305 to move, the limit rod 337 on the fixed support frame 304 will move through the limit plate 336, thereby achieving the effect of improving the stability of the support frame 304 and the connecting frame 305 during the movement process.

[0052] Reference Fig. 9 and Fig.10 As shown, in the present embodiment: the mounting mechanism 400 comprises two rotating seats 401, the two rotating seats 401 are respectively fixedly connected to the two sides of the storage box 301, the inner wall of the rotating seat 401 is rotatably connected with a rotating plate 402, the side of the rotating plate 402 is provided with a screw hole 403, the lower surface of the UAV body 100 is fixedly connected with two welding seats 404, the inner wall of the welding seat 404 is fitted with the rotating plate 402, the side of the welding seat 404 is threaded with a screw 405, the screw 405 is adapted to the size of the screw hole 403, by setting the mounting mechanism 400, the spray repair mechanism 300 can be easily disassembled and assembled, thereby facilitating personnel to clean or maintain the spray repair mechanism 300, and improving the service life of the spray repair mechanism 300.

[0053] The arc surface of the screw 405 is provided with a plurality of anti-skid patterns 406 , which are evenly distributed on the arc surface of the screw 405 . A person can rotate the screw 405 with the help of the anti-skid patterns 406 , thus achieving the effect of facilitating the rotation of the screw 405 .

[0054] One end of the screw rod 405 is fixedly connected with a guide block 407 , which has a conical structure. Since the guide block 407 fixed on one end of the screw rod 405 is relatively small, the connection between the screw rod 405 and the screw hole 403 can be easily adjusted.
