Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line maintenance, and in particular to a foreign body detection and cleaning device for a power transmission line. Background Art

[0002] The transmission line is realized by using a transformer to boost the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. Moreover, the transmission line is divided into overhead transmission lines and cable lines. When there are foreign objects in the transmission line, a foreign object detection and cleaning device is required to detect and clean it. However, the existing foreign object detection and cleaning device generally needs to adjust itself to different angles when detecting foreign objects in the line. When foreign objects need to be cleaned, it is impossible to detect the surrounding conditions, so foreign objects need to be cleaned only after the detection is completed, which increases the inspection time and reduces the detection efficiency. Moreover, when clamping the wires of the line, it is generally not easy to move along the line, so manual operation of the drone is required, which increases the labor burden and reduces the work efficiency of the staff. Moreover, it is generally not easy to clean foreign objects on the wires, and the staff needs to go to high altitude to clean them, which increases the cleaning burden and reduces the cleaning effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figures 1 to 4 A foreign body detection and cleaning device for a power transmission line includes a drone body 1, a foreign body detection component 2, a clamping component 3, and a cleaning component 4. The foreign body detection component 2 is installed on the outside of the drone body 1, the clamping component 3 is installed on the top of the drone body 1, and the cleaning component 4 is installed above the drone body 1; feet 5 are distributed and fixed on the outer wall of the bottom end of the drone body 1, and handles 6 are symmetrically fixed on the outer wall of the top end of the drone body 1. The drone body 1 is placed under the line tower by means of the handles 6, and then the drone body 1 is balanced by means of the feet 5; wings 7 are distributed and installed on the outer wall of the drone body 1 to control the drone body 1 and make the drone body 1 fly high in the air by means of the wings 7;

[0026] The foreign body detection assembly 2 includes a connecting plate 201, a first guide rail 202, a support plate 203, an arc-shaped protrusion 204, a first motor 205, a rotating frame 206, a slip ring 207, an ear block 208, a rotating shaft 209, a torsion spring 2010, a detection probe 2011 and an adjustment arc plate 2012. The outer side of the drone body 1 is fixedly connected to the connecting plate 201, the first guide rail 202 is fixedly connected to the outer wall of one side of the connecting plate 201, the first guide rail 202 is slidably connected to the slip ring 207, and the outer wall of the bottom end of the slip ring 207 is fixed to the outer wall of the bottom end of the slip ring 207. The rotating frame 206 is fixedly connected, and the first motor 205 is embedded and installed on the outer wall of the bottom end of the drone body 1, and the bottom end of the output shaft of the first motor 205 is fixed to the outer wall of the rotating frame 206. The outer side of the slip ring 207 is fixed with ear blocks 208, and the outer wall between the ear blocks 208 is installed with a detection probe 2011. The outer side of the detection probe 2011 is symmetrically fixed with a rotating shaft 209, and the other end of the rotating shaft 209 is rotatably connected to the outer wall of the ear block 208. A torsion spring 20 is fixed to the outer wall of one side of the ear block 208. 10, and the other end of the torsion spring 2010 is fixed to the outer wall of the detection probe 2011; an adjusting arc plate 2012 is fixed to the top outer wall of the detection probe 2011, and a support plate 203 is fixed to the top outer wall of the connecting plate 201. An arc-shaped protrusion 204 is fixed to the outer wall of one side of the support plate 203 at a position corresponding to the adjusting arc plate 2012. The first motor 205 is started to make the rotating frame 206 rotate back and forth in a small range. At this time, the detection probe 2011 and the adjusting arc plate 2012 are rotated along the arc on the support plate 203. The protrusion 204 moves, so that the rotating shaft 209 on the detection probe 2011 is adjusted up and down along the ear block 208, which is convenient for video detection of the wires on both sides of the equipment when cleaning foreign objects; the torsion spring 2010 is internally sleeved on the outer wall of the rotating shaft 209, and the number of torsion springs 2010 is six. When the adjustment arc plate 2012 is separated from the arc-shaped protrusion 204, then under the action of the torsion spring 2010, the rotating shaft 209 on the detection probe 2011 is reset along the ear block 208.

[0027] Working principle: First, place the drone body 1 under the line tower through the handle 6, and then use the footrest 5 to balance the drone body 1. At this time, control the drone body 1 to make it fly high in the air. At this time, start the detection probe 2011 to detect the surroundings, and then start the first motor 205 to rotate the rotating frame 206, so that the slip ring 207 rotates along the first guide rail 202 on the connecting plate 201, and expand the detection range through the detection probe 2011. When a foreign object is detected, the clamping component 3 is clamped to the wire. When cleaning the foreign object on the wire, the first motor 205 is started again to make the rotating frame 206 rotate back and forth in a small range. When the arc plate 2012 is adjusted away from the arc bulge 204, the rotating shaft 209 on the detection probe 2011 is adjusted up and down along the ear block 208, and then the detection probe 2011 is used to detect the wires on both sides of the device. When the arc plate 2012 is adjusted away from the arc bulge 204, the rotating shaft 209 on the detection probe 2011 is reset along the ear block 208 under the action of the torsion spring 2010. When cleaning foreign objects from the line, the surrounding conditions can also be detected. There is no need to clean foreign objects after the detection is completed, which reduces the detection time and improves the detection efficiency.

[0029] See also Figures 4 and 5 The clamping assembly 3 includes a first slide groove 301, a second motor 302, a bidirectional screw rod 303, a slider 304, a threaded hole 305, a vertical plate 306, a clamping arc plate 307 and an electromagnetic adsorption plate 308. The top of the drone body 1 is provided with a first slide groove 301, and the second motor 302 is embedded and installed on the inner wall of one side of the first slide groove 301. One end of the output shaft of the second motor 302 is fixedly connected to the bidirectional screw rod 303, and the other end of the bidirectional screw rod 303 is rotatably connected to the inner wall of the first slide groove 301. The slider 304 is symmetrically slidably connected in the first slide groove 301, and a threaded hole 305 is provided on the slider 304 corresponding to the position of the bidirectional screw rod 303. The top outer wall of the slider 304 is fixedly connected with a vertical plate 306, the top outer wall of the vertical plate 306 is fixedly connected with a clamping arc plate 307, and the top outer wall of the clamping arc plate 307 is installed with an electromagnetic adsorption plate 308.

[0030] When a foreign object is detected on the wire, the drone body 1 is first controlled to fly under the wire. At this time, the second motor 302 is started to rotate the bidirectional screw rod 303. Then, under the action of the threaded hole 305, the two sliders 304 are moved closer to each other along the first slide groove 301, so that the clamping arc plate 307 on the vertical plate 306 performs a preliminary clamping of the wire, and the clamping force is not high. Then, the electromagnetic adsorption plates 308 are started to adsorb each other, so that the upper part of the clamping arc plate 307 is adsorbed to avoid the clamping arc plate 307 falling off from the wire. The line can be clamped more loosely and a cleaning route is provided for the drone, thereby simplifying the operation process of the drone, reducing the labor burden, and improving the work efficiency of the staff.

[0031] Example 3

[0032] See also Figures 4 and 5 The cleaning component 4 includes a fixed plate 401, a third motor 402, a gear 403, a second guide rail 404, a rotating arc plate 405, a second slide 406, an arc-shaped rack 407 and a foreign matter crushing block 408.

The outer side of the rotating arc plate 405 is fixedly connected with an arc-shaped rack 407, and a meshing arrangement is arranged on the outer wall of one side of the arc-shaped rack 407. It is equipped with a gear 403, and a fixed plate 401 is symmetrically fixed to the outer side of the clamping arc plate 307. A third motor 402 is embedded and installed on the fixed plate 401, and one end of the output shaft of the third motor 402 is fixed to the outer wall of the gear 403. Foreign matter crushing blocks 408 are distributed and fixed on the outer wall of one side of the rotating arc plate 405; one side of the foreign matter crushing blocks 408 is provided with a chamfer, and the number of foreign matter crushing blocks 408 is twelve. By rotating the foreign matter crushing blocks 408 on the arc plate 405, foreign matter on the wires is rotated and crushed, making it convenient to clean foreign matter from the wires.

[0033] After the wire is clamped, the clamping arc plate 307 on the drone body 1 is controlled to move along the wire. When encountering foreign objects, the third motor 402 on the four fixed plates 401 is started to rotate the gear 403, and then a gear ring is formed by the spliced ​​arc rack 407. Then, with the cooperation of the two arc racks 407, the second slide groove 406 on the rotating arc plate 405 is rotated along the second guide rail 404. Then, the foreign object crushing block 408 on the rotating arc plate 405 is rotated and crushed to remove the foreign objects from the wire. This can clean the foreign objects on the wire without the need for staff to go to high altitudes for cleaning, which reduces the cleaning burden and improves the cleaning effect.
