Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and transformation lines, and in particular to a drone for deicing power transmission and transformation lines. Background Art

[0002] Transmission line deicing drones are devices that use drones to remove ice from transmission lines that are difficult to climb. For example, application No. 303111541916.4 provides a deicing system for high-voltage transmission lines, which includes a drone, a control system, and a deicing device, wherein the deicing device is installed at the bottom of the drone, and a controller is installed at the bottom of the drone. The drone and the controller establish remote communication with the control system, so that the control system can remotely control the operation of the drone and the controller.

[0033] In this embodiment, reference Figure 3 and Figure 6 The mounting mechanism 4 includes a fixing seat 401 fixedly connected to the bottom of the drone body 1, a connecting seat 402 is slidably connected to the outer wall of the fixing seat 401 at the position connected to the de-icing box 301, a positioning pin 403 is slidably connected to the inside of the fixing seat 401 and close to the connecting seat 402, a pushing plate 404 is fixedly connected to the outer wall of the positioning pin 403 and in the fixing seat 401, a return spring 405 is fixedly connected to the outer wall of the pushing plate 404 and at a position away from the positioning pin 403, an extrusion plate 406 is slidably connected to the outer wall of the pushing plate 404 and at a side away from the positioning pin 403, and a pushing screw 407 is rotatably connected to the outer wall of the extrusion plate 406 and at a side away from the pushing plate 404;

[0034] The fixing seat 401, the connecting seat 402 and the positioning pin 403 are all made of stainless steel, the connecting seat 402 is designed in a C-shaped structure, the positioning pin 403 penetrates the fixing seat 401 and extends to the connecting seat 402, the reset spring 405 and the fixing seat 401 as well as the connecting seat 402 and the de-icing box 301 are all fixedly connected, the pushing plate 404 and the extrusion plate 406 are all made of aluminum alloy, the positioning pin 403, the pushing plate 404 and the reset spring 405 are all provided with multiple groups, the pushing plate 404 and the extrusion plate 406 are both designed in a trapezoidal structure, the pushing screw 407 penetrates and extends outside the fixing seat 401, and the pushing screw 407 and the fixing seat 401 are connected by a threaded connection.

[0035] The working process of the present invention is as follows: when the deicing drone for power transmission and transformation lines designed by the present invention is in operation, the pushing screw 407 is rotated, and the rotating pushing screw 407 pulls the extrusion plate 406 to move outward, and the extrusion plate 406 moving outward no longer resists the pushing plate 404, and the reset spring 405 pulls the pushing plate 404 to move inward, and the pushing plate 404 moving inward drives the positioning pin 403 to exit the connecting seat 402 and enter the fixing seat 401, and the positioning pin 403 no longer blocks the connecting seat 402, and the deicing box 301 is pulled to be taken out from the bottom of the drone body 1, and then the deicing box 301 is pulled out. The liquid storage tank 314 is filled with liquid carbon dioxide, and then the de-icing box 301 is reinserted into the bottom of the drone body 1, the fixing seat 401 is inserted into the connecting seat 402, and the pushing screw 407 is rotated in the opposite direction. The pushing screw 407 that rotates in the opposite direction pulls the extrusion plate 406 to move inward, and the extrusion plate 406 that moves inward squeezes the pushing plate 404. The pushing plate 404 moves outward after being squeezed, and the pushing plate 404 that moves outward drives the positioning pin 403 to enter the connecting seat 402, and the positioning pin 403 re-locks the connecting seat 402, and the de-icing box 301 is installed at the bottom of the drone body 1;

[0036] The remote controller 2 starts the drone body 1, and the drone body 1 drives the de-icing box 301 to fly into the air. The remote controller 2 starts the driving motor 321 through the wireless controller 320. The driving motor 321 drives the worm wheel 315 to rotate through the worm 316. The rotating worm wheel 315 drives the de-icing plate 309 and the oscillating plate 306 to rotate upward to a horizontal state through the rotating shaft 305, thereby reducing the wind-receiving area of ​​the de-icing box 301. The drone body 1 drives the de-icing box 301 to fly above the power transmission and transformation line. The operator adjusts the flight path of the drone body 1 according to the image taken by the aerial camera of the drone body 1, so that the drone body 1 moves to the ice hanging position on the power transmission and transformation line. The driving motor 321 drives the worm wheel 315 to rotate in the opposite direction through the worm 316. The reversely rotating worm wheel 315 drives the de-icing plate 309 and the oscillating plate 306 to rotate downward to a vertical state through the rotating shaft 305.

[0037] The wireless controller 320 starts the electric slide rail 302, and the electric slide rail 302 drives the sliding seat 304 to move toward the center through the slide table 303. The sliding seat 304 drives the de-icing plate 309 and the vibration plate 306 to approach the ice hanging, so that the vibration plate 306 is close to the ice hanging. The wireless controller 320 starts the vibrator 307, and the vibrator 307 drives the vibration plate 306 to vibrate at a high frequency. When the vibration frequency of the vibration plate 306 is the same as the fixed frequency of the ice hanging, the ice hanging will vibrate together with the vibration plate 306. A large number of cracks will be generated inside the ice hanging due to the vibration. The wireless controller 320 turns off the vibrator 307, and the vibrator 307 no longer drives the vibration plate 306 to vibrate The wireless controller 320 starts the electromagnetic heating coil 311, and the electromagnetic heating coil 311 heats the cracking cone 310. The temperature of the cracking cone 310 rises, and the electric slide rail 302 drives the sliding seat 304 and the deicing plate 309 to continue to approach the ice hanging through the slide table 303. The deicing plate 309 drives the high-temperature cracking cone 310 to insert into the ice hanging. The high-temperature cracking cone 310 melts the ice layer in contact with it, and the cracking cone 310 can be easily inserted into the deep of the ice hanging. The wireless controller 320 turns off the electromagnetic heating coil 311, and the electromagnetic heating coil 311 no longer heats the cracking cone 310. The heat in the cracking cone 310 is absorbed by the ice hanging, and the temperature of the cracking cone 310 decreases.

[0038] The wireless controller 320 opens the solenoid valve 322, and the liquid carbon dioxide in the liquid storage tank 314 flows into the liquid outlet pipe 312 through the guide pipe 313. The liquid carbon dioxide in the liquid outlet pipe 312 will push the sealing plug 317 and spray out from the liquid outlet pipe 312. The sprayed carbon dioxide will rush into the ice hanging and flow along the cracks in the ice hanging. The wireless controller 320 starts the electromagnetic heating coil 311 again, and the electromagnetic heating coil 311 heats the liquid carbon dioxide in the ice hanging through the cracking cone 310. The liquid carbon dioxide is vaporized by the heat, and the pressure and volume of the vaporized carbon dioxide increase sharply. The expanded carbon dioxide gas will crack the ice hanging along the cracks in the ice hanging, and the cracked ice hanging will be detached from the power transmission and transformation line.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
