Description
Technical Field
[0001] The invention belongs to the technical field of foreign matter removal from power transmission lines, and in particular relates to a foreign matter removal device for power transmission lines. Background Art
[0002] With the rapid development of power networks, the coverage of transmission lines continues to expand, and line maintenance work faces huge challenges. Transmission lines are often exposed to the natural environment and foreign objects (such as kite strings, plastic films, branches, bird nests, etc.) are attached. These foreign objects may cause line short circuits, insulation damage, and even power outages. Traditional foreign object removal methods mainly rely on manual tower climbing or insulated boom truck assistance, which has problems such as low efficiency, high risk, and high cost. In recent years, the development of drone technology has provided new ideas for transmission line inspection and maintenance, but the removal devices carried by existing drones generally have the following defects: 1. Insufficient adaptability: It is difficult to adapt to cables of different diameters or complex structures (such as isolation rods), and the cleaning effect is limited; 2. Single function: Most devices can only remove light foreign matter, and have poor handling capabilities for tightly entangled or hard foreign matter; 3. Poor stability: The device is prone to deviation or jamming during the cleaning process, affecting the balance of the aircraft; 4. Low degree of automation: It relies on frequent manual intervention and cannot achieve efficient and continuous operation.

[0032] A motor mounting plate 22 is mounted on the front side of the lower end face of the lifting plate 3, sliding in the front-to-back direction. A T-block is fixedly mounted on the upper end face of the motor mounting plate 22. A T-slot extending horizontally front to back is provided on the front side of the lower end face of the lifting plate 3, and the T-block slides and engages within the T-slot. An electric push rod 23 is fixedly mounted on the lower end face of the lifting plate 3.

The electric push rod 23 drives the motor mounting plate 22 to slide back and forth. A second motor 24 is fixedly mounted on the lower end face of the motor mounting plate 22. The output shaft of the second motor 24 points horizontally and rearward, and the output shaft of the second motor 24 slides and engages within the support groove 9 of the left-side cleaning half ring 4.
[0033] A square engaging groove 25 is provided at the front end of the left rotating shaft 17. This engaging groove 25 communicates with the through groove 21 of the left cleaning half ring 4.

An arc-shaped pressing strip 28 is mounted on the front and rear sides of the fixing plate 27. The cross section of the pressing strip 28 is an L-shaped structure. The front and rear pressing strips 28 press the front and rear edges of the fixing plate 27. The front and rear pressing strips 28 are fixedly connected to the front and rear end faces of the cleaning half-ring 4 by screws, thereby fixing the fixing plate 27 to the cleaning half-ring 4. A plurality of fixing rods 29 are fixedly mounted on the inner arc surface of the fixing plate 27. The axis of the fixing rod 29 is arranged along the radial direction of the cleaning half-ring 4. The cleaning scraper 6 is rotatably mounted on the end of the fixing rod 29 away from the fixing plate 27.
[0035] A semi-circular filter plate 30 is fixedly arranged on the rear end faces of the two cleaning half rings 4 .
[0036] A mounting plate is fixedly mounted on the lower end face of the right cleaning half ring 4, on which are disposed a plurality of cleaning hooks 31. A clearance groove is provided on the lower end face of the left cleaning half ring 4. When the left and right cleaning half rings 4 are combined into a circular ring structure, the mounting plate and cleaning hooks 31 on the right cleaning half ring 4 are located within the clearance groove on the left cleaning half ring 4.
[0037] Two symmetrical vertical drive rods 12 are fixed to the rear end of the lower end of the lifting plate 3. A spherical protrusion 32 is fixed to the front of the lower end of each drive rod 12. The two spherical protrusions 32 respectively abut the rear end surfaces of the two power half rings 5. A circular arc-shaped support plate 33 is fixed to the side of the lower ends of the two drive rods 12 that are close to each other. The two support plates 33 are in sliding contact with the inner side of the rear end of the two power half rings 5.
[0038] Multiple groups of fixed cylinders 34 are provided on the inner arc surface of each power half-ring 5. The multiple fixed cylinders 34 within each group are equidistantly arranged along the axial direction of the power half-ring 5. The fixed cylinder 34 is a cylindrical structure with one end open. The axis of the fixed cylinder 34 is arranged along the radial direction of the power half-ring 5. The end of the fixed cylinder 34 away from the opening is fixedly connected to the inner arc surface of the power half-ring 5. The connecting rod 7 is slidably arranged inside the opening of the fixed cylinder 34. The driving wheel 8 is rotatably arranged on the outer end of the connecting rod 7. A circular connecting plate 35 is fixedly provided on the inner end of the connecting rod 7. The connecting plate 35 is slidably arranged inside the fixed cylinder 34. A pressure spring 36 is fixedly provided on the inner end of the fixed cylinder 34. The pressure spring 36 is fixedly connected to the connecting plate 35.
[0039] The working principle of the present invention is: When the device is in the initial state, the two cleaning half rings 4 and the two power half rings 5 are in a closed state, and the chain 15 is wound onto the reel 14, so that the lifting plate 3 and the cleaning half rings 4 and the power half rings 5 are all located inside the fixed box 2.
[0040] When foreign matter on the cable needs to be removed, aircraft 1 is controlled to take off. After takeoff, first motor 13 is controlled to drive reel 14 in reverse rotation, releasing chain 15 from reel 14 and causing spring 16 to rebound, causing lift plate 3 to descend within fixed box 2, moving both power half ring 5 and cleaning half ring 4 outside fixed box 2. Then, electric push rod 23 is controlled to retract, causing engaging block 26 on the output shaft of second motor 24 to engage within engaging groove 25 at the end of left rotating shaft 17. Second motor 24 is controlled to rotate, driving left rotating shaft 17 and left cleaning half ring 4 to rotate. Since the left and right rotating shafts 17 are connected by meshing driving gear 18 and driven gear 19, this also causes right rotating shaft 17 and right cleaning half ring 4 to rotate, causing the two cleaning half rings 4 to open, which in turn drives the two power half rings 5 to open.
[0041] When the aircraft 1 flies over the cable that needs to be cleared of foreign objects, it is controlled to gradually descend, positioning the cable between the two open power half-rings 5 and the two open clearing half-rings 4. The second motor 24 is then controlled to rotate in the opposite direction, gradually closing the two clearing half-rings 4 and the two power half-rings 5 so that they are positioned around the cable. Simultaneously, the piston rod of the electric push rod 23 is controlled to extend, causing the engaging block 26 on the output shaft of the second motor 24 to disengage from the engaging groove 25 on the left rotating shaft 17. The disengaged engaging block 26 then resides within the through groove 21 of the clearing half-ring 4.
[0042] When the closed cleaning half-ring 4 and the power half-ring 5 are placed over the cable, the drive wheels 8 inside the power half-ring 5 abut against the cable's outer surface. The aircraft 1 then flies along the cable's extension direction. The spherical protrusions 32 at the lower ends of the drive rods 12 propel the two power half-rings 5 forward, driving the cleaning half-ring 4 forward with them. Because the drive wheels 8 abut against the cable's outer surface, and the axes of the drive wheels 8 and the power half-ring 5 are angled, the power half-ring 5 rotates as it moves forward, driving the cleaning half-ring 4 forward as it also rotates. This allows the cleaning scraper 6 inside the cleaning half-ring 4 to rotate as it moves forward, shredding foreign matter from the cable's outer surface. A filter plate 30 is positioned between the power half-ring 5 and the cleaning half-ring 4, allowing the shredded foreign matter to accumulate on the filter plate 30, preventing interference with the normal operation of the power half-ring 5. The filter plate 30 is provided with a tearable adhesive, and the shredded foreign matter can be adhered to the adhesive to prevent it from being directly scattered after the two cleaning half rings 4 are opened.
[0043] During the rotation of the power half-ring 5, the two rear support columns 11 slide within the support grooves 9 of the two power half-rings 5, thereby supporting the rotating power half-ring 5. During the rotation of the cleaning half-ring 4, the front support column 11 slides within the support groove 9 of the cleaning half-ring 4. Simultaneously, the output shaft of the second motor 24 also slides within the support groove 9 of the cleaning half-ring 4, thereby supporting the rotating cleaning half-ring 4. During the rotation of the cleaning half-ring 4, the clamping block 26 is located within the through grooves 21 of the two cleaning half-rings 4, ensuring that the rotation of the cleaning half-ring 4 is not interfered with.
[0044] Because the cable is equipped with a spacer rod, when the aircraft 1 encounters the spacer rod, the aircraft 1 stops flying forward, and the piston rod of the electric push rod 23 retracts again, causing the clamping block 26 on the output shaft of the second motor 24 to engage with the inside of the clamping groove 25 of the rotating shaft 17. The second motor 24 is then controlled to rotate, causing the two cleaning half-rings 4 and the two power half-rings 5 to open. After passing the spacer rod, the two cleaning half-rings 4 and the two power half-rings 5 close again, wrapping around the outside of the cable, and the electric push rod 23 is controlled to extend, disengaging the clamping block 26 from the clamping groove 25. When the two cleaning half-rings 4 are opened, the cleaning hook 31 at the lower end of the right cleaning half-ring 4 can hook and remove foreign objects on the spacer rod.
[0045] The device is also equipped with displacement sensors, cameras and other supporting equipment to monitor the status of the cleaning half ring 4 so that it can be restored to its initial state when its rotation stops, so that the clamping block 26 on the output shaft of the second motor 24 can be inserted into the clamping groove 25.
[0046] After the cleaning is completed, the first motor 13 is controlled to rotate forward, so that the chain 15 is wound onto the reel 14, and the lifting plate 3 and the cleaning half ring 4 and the power half ring 5 are retracted into the fixing box 2. Then the aircraft 1 lands, and the support frames on both sides land smoothly.
[0047] To accommodate cables of varying diameters, the fixing rods 29 of varying lengths can be replaced within the cleaning half ring 4. Simultaneously, when the drive wheel 8 contacts the outer surface of the cable, the pressure spring 36 is compressed. The compressed pressure spring 36 ensures that the drive wheel 8 always maintains close contact with the outer surface of the cable, allowing the power half ring 5 to accommodate cables of varying diameters.
[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
