The balancing part 5 is arranged on the driving part, and the balancing part 5 is connected to the mounting part 1, and the balancing part 5 is used to keep the crushing part 3 horizontal. The battery 6 is connected to the cleaning part 2, the crushing part 3, the driving part 4 and the balancing part 5, and provides power.

[0050] The beneficial effects of the cable cleaning device for power grid operation provided by this embodiment are as follows: compared with the prior art, the cable cleaning device for power grid operation provided by this embodiment is provided with an installation part 1, so that the cable cleaning device for power grid operation of the present invention can be installed on the cable, and by providing a driving part 4, the cable cleaning device for power grid operation of the present invention can be moved on the cable, and by providing a cleaning part 2, ice in the forward direction of the installation part 1 can be cleaned. Compared with manual cleaning, the cable cleaning device for power grid operation of the present invention does not require staff to walk on the cable during cleaning, and can clean automatically, which greatly reduces the difficulty of removing ice on the cable. In addition, by providing a balancing part 5 and a crushing part 3, the cable cleaning device for power grid operation of the present invention can crush the cleaned and removed ice, and discharge it into powder to prevent injury to people or vehicles under the cable.

[0051] Combine Figure 2 and Figure 3 As shown, the mounting portion 1 is box-shaped, including an upper box body 101 and a lower box body 104, which facilitates the mounting portion 1 to be set on the cable. During installation, the mounting portion 1 can be installed on the cable by simply snapping the upper box body 101 and the lower box body 104 together on both sides of the cable.

[0052] Specifically, the upper box body 101 is in the shape of a rectangular parallelepiped, and is provided with an upper half groove 102 with a semicircular cross section. Upper first fixing ears 103 are provided on both sides of the upper box body 101. The lower box body 104 is in the shape of a rectangular parallelepiped, and is provided with a lower half groove 105 with a semicircular cross section. Lower first fixing ears 106 are provided on both sides of the lower box body 104.

[0053] When the upper case 101 and the lower case 104 are fastened together, bolts are screwed onto the corresponding upper first fixing ears 103 and lower first fixing ears 106, securing the upper case 101 and the lower case 104. The upper half slot 102 and the lower half slot 105 are fastened together to form a through hole. The diameter of the through hole is not less than the diameter of the cable, and the cable is passed through the through hole. The provision of the upper first fixing ears 103 and the lower first fixing ears 106 facilitates the mutual fixation between the upper case 101 and the lower case 104.

[0054] Combine Figure 1 and Figure 7 As shown, the cleaning unit 2 comprises two cleaning halves 201, a driven gear, a first drive member 203, a first active feed gear, and multiple ice-breaking blades 205. The two cleaning halves 201 interlock to form a cleaning barrel. The inner diameter of the barrel is the same as the diameter of the cable. The barrel is sleeved over the cable and rotatably mounted on the mounting unit 1. Ice-breaking blades 205 are located at one end of the barrel, which is connected to the mounting unit 1. As the mounting unit 1 moves forward, the rotating barrel drives the ice-breaking blades 205, breaking any ice trapped on the cable.

[0055] The first driven teeth 202 are evenly arranged on the outer wall of the cleaning barrel along the circumference of the cleaning barrel. The first driving member 203 is disposed on the mounting portion 1. The first driving gear 204 is connected to the power output end of the first driving member 203. The first driving gear 204 meshes with the first driven teeth 202, enabling the first driving member 203 to drive the cleaning barrel to rotate. In this embodiment, the first driving member 203 is selected to be a motor, but other suitable components may also be used.

[0056] In addition, upper housing 101 is provided with an upper half-slot 107, which has a T-shaped cross section and is in contact with upper half-slot 102. Lower housing 104 is provided with a lower half-slot 108, which has a T-shaped cross section and is in contact with lower half-slot 105. When upper housing 101 and lower housing 104 are fastened together, upper half-slot 107 and lower half-slot 108 snap together to form a stopper.

[0057] A stopper 206 is provided on the outer wall of the cleaning half-tube 201. When the two cleaning tubes are fastened together, the stopper 206 is fastened to form a stopper ring. The stopper ring is adapted to the stopper groove and inserted into the stopper groove, allowing the cleaning tube to rotate relative to the mounting portion 1 while preventing the cleaning tube from being separated from the mounting portion 1. This arrangement also facilitates installation and removal.

[0058] Combine Figure 1 、 Figure 5 and Figure 6 As shown, the drive unit 4 is annular and is mounted on the cable. It includes two drive half-rings 401. Second fixing ears 402 are provided on either side of the drive half-rings 401. When the two drive half-rings 401 are fastened together to form the drive unit 4, bolts are screwed onto the corresponding second fixing ears 402 to secure the two drive half-rings 401. The provision of the drive half-rings 401 facilitates mounting the drive unit 4 on the cable.

[0059] Furthermore, the inner wall of the drive half ring 401 is provided with a plurality of mounting grooves 403. A second drive member 404 is disposed within each of these grooves. A first drive shaft 405 is disposed at the power output end of the second drive member 404. A drive wheel 406 is disposed on the first drive shaft 405. Partial portions of the drive wheel 406 extend outside the mounting grooves 403 and abut against the cable. When the second drive member 404 rotates, the drive unit 4 can move along the cable's axis. While the second drive member 404 is preferably a motor, other suitable components may also be employed.

[0060] Combine Figure 1 、 Figure 6 and Figure 8As shown, the balancing part 5 includes a detection mechanism and a driving mechanism 508, wherein the detection mechanism is provided on the mounting part 1 and is used to detect whether the mounting part 1 is kept level. The driving mechanism 508 is provided on the driving part, and the driving mechanism 508 is electrically connected to the detection mechanism, and the driving mechanism 508 is fixedly connected to the mounting part 1.

[0061] When the detection mechanism detects that the mounting portion 1 is deflected, the driving mechanism 508 drives the mounting portion 1 to rotate in the opposite direction to keep the crushing portion horizontal, thereby allowing the crushing portion 3 to be received under the cleaning barrel to receive and crush the ice crushed by the cleaning barrel.

[0062] As a preferred technical solution, the detection mechanism includes a detection box 501, a forward rotation circuit 503, a reverse rotation circuit 504, a forward rotation contact 505, a reverse rotation contact 506, and mercury 507. The detection box 501 is located on top of the mounting portion 1 and includes a housing 502 therein. When the forward rotation circuit 503 is in the off state and is on, a drive mechanism 508 drives the mounting portion 1 in forward rotation. When the reverse rotation circuit 504 is in the off state and is on, a drive mechanism 508 drives the mounting portion 1 in forward rotation. The forward rotation contact 505 is located on a side wall of the detection box 501. The reverse rotation contact 506 is located on a side wall of the detection box, and the forward rotation contact 505 and the reverse rotation contact are located on two opposing side walls of the detection box 501. The side walls of the detection box 501 where the forward rotation contact 505 and the reverse rotation contact 506 are located are parallel to the axis of the cable. Mercury 507 is disposed in the accommodating cavity 502 and is connected to the forward circuit 503 and the reverse circuit.

[0063] When the detection box 501 is in a horizontal state, the liquid level of the mercury 507 is below the forward contact 505 and the reverse contact 506. When the detection box 501 is deflected in the forward direction, the mercury 507 contacts the reverse contact 506, making the reverse circuit 504 conductive; when the detection box 501 is deflected in the reverse direction, the mercury 507 contacts the forward contact 505, making the forward circuit 503 conductive, so that when the detection box 501 is deflected, the driving mechanism 508 can drive the mounting part 1 to rotate back to a horizontal state.

[0064] In addition, the drive mechanism 508 includes two mounting half rings 509, two driving half cylinders 511, two connecting rods 512, a plurality of second driven gears 513, a third driving gear, and a second driving gear 514. The two mounting half rings 509 are used to buckle together to form a mounting ring. The mounting ring is sleeved on the outside of the driving unit 4. The inner wall of the mounting half ring 509 is provided with a positioning block 510. When the two mounting half rings 509 are buckled together to form the mounting ring, the positioning block 510 is buckled into a positioning ring. The outer wall of the driving half ring 401 is provided with a positioning half groove 407. When the two driving half rings 401 are buckled together to form the driving unit 4, the positioning half groove 407 is buckled into a positioning groove, and the positioning ring is located in the positioning groove. The two mounting half rings 509 are provided to facilitate the mounting ring to be sleeved on the driving unit 4. At the same time, the provision of the positioning ring and the positioning groove allows the mounting ring to be both fixed axially relative to the driving unit 4 and rotatable relative to the driving unit 4.

[0065] The two driving half cylinders 511 are used to buckle together to form a driving cylinder, one end of which is fixedly connected to the mounting portion 1. The two driving half cylinders 511 correspond one to one with the two mounting half rings 509. There are two driving half cylinders 511, which can facilitate the driving cylinder to be sleeved on the cable.

[0066] Two connecting rods 512 are N-shaped and connected between the corresponding mounting half-rings 509 and the driving half-cylinders 511. This allows the mounting rings to be fixed relative to the driving cylinder. When the driving unit 4 moves, it can drive the mounting rings, which in turn drives the driving cylinder, thereby driving the mounting unit 1. In addition, the second fixing ears 402 are provided with avoidance grooves that cooperate with the N-shaped connecting rods 512 to prevent the second fixing ears 402 from interfering with the rotation of the connecting rods 512 with the mounting ring.

[0067] In this embodiment, a plurality of second driven teeth 513 are arranged on the inner wall of the drive cylinder uniformly along the circumference of the drive cylinder. A mounting groove 403 is provided at the end of one driving half ring 401, and the third driving member is disposed in the mounting groove 403. A second driving gear 514 is connected to the power output end of the third driving member, and the second driving gear 514 meshes with the second driven teeth 513. The third driving member is simultaneously connected to the forward rotation circuit 503 and the reverse rotation circuit 504. When the forward rotation circuit 503 is connected, the third driving member rotates forward; when the reverse rotation circuit 504 is connected, the third driving member rotates reversely. Here, the third driving member is selected to be a motor.

[0068] Finally, the crushing unit 3 comprises two mounting plates 301, two crushing rollers 302, two fourth drive members, two first guide plates 303, and two second guide plates 304. The two mounting plates 301 are located at the bottom of the mounting unit 1 and are spaced apart. The two crushing rollers 302 rotate between the two mounting plates 301. The two crushing rollers 302 are parallel and spaced apart. The two crushing rollers 302 rotate in opposite directions, crushing the ice between them. Two fourth drive members are located on one of the mounting plates 301, corresponding one to each crushing roller 302. The crushing rollers 302 are connected to the power output of their respective fourth drive members, which drive the crushing rollers 302 to rotate.

[0069] Two first guide plates 303 are located at the bottom of the mounting portion 1, one on each side of the crushing rollers 302. The first guide plates 303 are used to guide material between the crushing rollers 302 for crushing. The second guide plates 304 are arranged at an angle, with their front ends extending outside the mounting portion 1 and located below the cleaning barrel. The second guide plates 304 are used to receive crushed ice and guide it between the crushing rollers 302.
