In the present embodiment, the adjusting mechanism includes a first fixing ring 14, a second fixing ring 10, a connecting plate 11, a positioning ring, a first spring telescopic rod 12 and a plurality of articulated connecting rods 13. The first fixing ring 14 is movably installed in the outer regulation case 3 in the left-right direction and is slidably provided in the front-rear direction, and the outer peripheral wall of the wire barrel 5 is connected to the inner ring of the first fixing ring 14 through a first one-way bearing arranged only to enable the counterclockwise rotation of the wire barrel 5 with respect to the first fixing ring 14. The second fixing ring 10 is disposed at the rear side of the first fixing ring 14, movably mounted to the outer adjustment case 3 in the left-right direction, and disposed coaxially with the second fixing ring 10. The connection plate 11 is provided inside the second fixed ring 10 by a second one-way bearing arranged to allow only counterclockwise rotation of the connection plate 11 with respect to the second fixed ring 10. The positioning ring is arranged on the rear end face of the second fixing ring 10, and the connecting plate 11 is arranged on the inner side of the positioning ring in an initial state; the first spring telescopic rod 12 and the first fixing ring 14 are coaxially arranged, one end of the first spring telescopic rod is connected to the connecting plate 11, and the other end of the first spring telescopic rod is connected to the wire connecting cylinder 5.

When the wind power received by the cable 4 is small, the swing amplitude is small, at this time, the cable 4 pulls the wiring cylinders 5 at the two ends to move forwards so as to be close to each other, and the wiring cylinders 5 drive the connecting plate 11 to move forwards through the plurality of hinged connecting rods 13, so that the second one-way bearing is in contact with the second fixing ring 10. Because the effect of articulated connecting rod 13, wire barrel 5 has anticlockwise rotation's trend when the outer lane of the one-way bearing of second contacts the back with the solid fixed ring 10 of second, and connecting plate 11 has clockwise rotation's trend, and at this time because the effect of the one-way bearing of second, connecting plate 11 can not clockwise rotate, so wire barrel 5 can anticlockwise rotation, and it twists reverse to drive cable 4, gets rid of the ice and snow on the cable 4.

When wind power disappears, the first spring telescopic rod 12 can pull the first fixing ring 14 to move backwards, in the process, due to the effect of the first one-way bearing, the wire connecting cylinder 5 cannot rotate, and the connecting plate 11 can rotate anticlockwise.

In the present embodiment, the ratchet mechanism includes the adjustment block 15, the first ratchet plate 22, the adjustment slider 18, and the ratchet bar 21. The adjustment block 15 is slidably provided in the circumferential direction of the first fixing ring 14. The first ratchet plate 22 is disposed on a side wall of the mounting groove. The adjusting slide block 18 is disposed on the front side of the adjusting block 15 and abuts against the rear end of the power storage spring 16, and the adjusting block 15 abuts against the rear end surface of the adjusting slide block 18 in the initial state. The ratchet bar 21 extends in the front-rear direction, the front end is fixedly connected to the adjusting slider 18, and the left and right sides are respectively provided with a second ratchet plate 23 and a third ratchet plate 24. The second ratchet plate 23 and the first ratchet plate 22 are configured to allow only the ratchet bar 21 to move forward along the mounting groove. The adjustment block 15 is provided with a latch, the latch and the third ratchet plate 24 being configured to only allow the adjustment block 15 to slide backwards relative to the ratchet bar 21. When the adjusting block 15 moves forward along with the first fixing ring 14, the adjusting block 15 pushes the adjusting slide block 18 to slide forward relative to the mounting groove, and the power storage spring 16 is pressed to store power of the power storage spring 16. When the adjusting block 15 moves backward with the first fixing ring 14, the first and

second ratchet plates

22 and 23 limit the movement of the ratchet bar 21, so that the adjusting block 15 moves backward with respect to the adjusting slider 18, preventing the power accumulating spring 16 from being restored.

In this embodiment, the rear end of the power storage spring 16 is connected to the striking rod 6, the upper portion of the striking rod 6 is provided with a limiting strip 612 extending along the length direction thereof, the adjusting slider 18 is slidably mounted to the striking rod 6 along the left-right direction, a sliding groove with a downward opening is formed in the adjusting slider 18, the limiting strip 612 is located in the sliding groove, the right side of the limiting strip 612 is in contact with the groove wall of the sliding groove in the initial state, and a gap is formed between the left side of the limiting strip 612 and the groove wall of the sliding groove. The resetting mechanism comprises a first telescopic plate 17, a fixture block 101, a fixed plate 25 and a second telescopic plate 19. The first expansion plate 17 is mounted on the other side wall of the mounting groove through a plurality of springs.

When the power storage spring 16 is compressed to the limit position, the adjusting slider 18 moves to the front end of the mounting groove, the fixture block 101 is pushed forward, the fixture block 101 is separated from the gap between the first expansion plate 17 and the groove wall of the mounting groove, and the first expansion plate 17 can move left and right.

At this time, if the wind power is increased, the first fixing ring 14 is pulled forwards, and the first fixing ring 14 is also pulled towards the left side surface and the right side surface, so that the cable 4 drives the first fixing ring 14 to move left and right through the cable connecting cylinder 5. When the first fixing ring 14 drives the adjusting block 15 to extrude the second expansion plate 19, the clamping block 101 of the adjusting block 15 is separated from the third ratchet plate 24, and then the second expansion plate 19 drives the fixing plate 25 to move rightwards through the plurality of springs when the adjusting block 15 continues to move, the fixing plate 25 drives the adjusting slider 18 and the ratchet bar 21 to move rightwards, so that the second ratchet plate 23 is separated from the first ratchet plate 22, the power storage spring 16 is released, and the adjusting slider 18 and the striking rod 6 are pushed to move backwards. When the striking rod 6 has a large speed, the adjusting slide block 18 is made to strike the adjusting block 15, then the first fixing ring 14 is struck to the initial position, and the second one-way bearing is separated from the second fixing ring 10 and moves to the positioning ring, at which time the twisting of the cable 4 is released, and the ice and snow on the cable are removed again. At this time, the first fixing ring 14 rotates at the center of the circular track, and the second one-way bearing rotates integrally relative to the positioning ring, so that the reset is completed.

In this embodiment, a guiding ring groove is formed on the outer peripheral wall of the second fixing ring 10, the adjusting block 15 is T-shaped, and the upper end of the adjusting block is located in the guiding ring groove and slidably disposed along the guiding ring groove, so as to drive the adjusting block 15 to horizontally move when the first fixing ring 14 horizontally moves.

In this embodiment, a positioning ring groove is formed in the inner peripheral wall of the outer adjusting shell 3, the first fixing ring 14 is located at the positioning ring groove in an initial state, a guide sliding groove is formed in the front end of the outer adjusting shell 3, and the rear end of the guide sliding groove is communicated with the positioning ring groove; the outer end of the first fixing ring 14 is provided with a limiting block 9 capable of sliding along the guide sliding groove, so that the first fixing ring 14 can slide back and forth along the outer adjusting shell 3 conveniently. The left and right sides of the first fixing ring 14 and the second fixing ring 10 are provided with positioning openings, second spring telescopic rods 102 are inserted into the positioning openings, and one ends of the second spring telescopic rods 102 are connected with the outer adjusting shell 3, so that the first fixing ring 14 and the second fixing ring 10 can move left and right under stress conveniently.

In the present embodiment, a weight 611 is connected to the rear end of the striker 6 to increase the inertia of the striker 6.

In the embodiment, the number of the ice and snow removing mechanisms 1 of the self-cleaning cable ice and snow removing device is two, and the two ice and snow removing mechanisms 1 are arranged in parallel and in reverse; the ice and snow removing device for the self-cleaning type cable further comprises a connecting piece 20, wherein the connecting piece 20 is connected with the two cables 4 connected with the connecting cylinder 5.

When in use, the self-cleaning cable ice and snow removing device is applied to the environment with larger wind power. When wind power is small, the swing amplitude of the cable 4 is small, at this time, the cable 4 pulls the cable barrels 5 at the two ends to move forwards to be close to each other, the cable barrels 5 drive the connecting plate 11 to move forwards through the plurality of hinged connecting rods 13, and the connecting plate 11 drives the second one-way bearing to slide forwards to be in contact with the second fixing ring 10. When a wire barrel 5 continues to move forward after the unidirectional bearing slides forward and contacts with the second fixing ring 10, the wire barrel 5 tends to rotate counterclockwise, the connecting plate 11 tends to rotate clockwise, at this time, due to the effect of the second unidirectional bearing, the connecting plate 11 cannot rotate clockwise, so the wire barrel 5 can rotate counterclockwise, the cable 4 is driven to twist, ice and snow on the cable are removed, the first fixing ring 14 can drive the adjusting block 15 to move forward when the wire barrel 5 rotates counterclockwise, the adjusting block 15 pushes the adjusting slide block 18 to slide forward relative to the mounting groove, the force storage spring 16 is squeezed, and the force storage spring 16 stores force. When wind power disappears, the first spring telescopic rod 12 can pull the first fixing ring 14 to move backwards, in the process, due to the effect of the first one-way bearing, the wire connecting cylinder 5 cannot rotate, and the connecting plate 11 can rotate anticlockwise. When the first fixing ring 14 moves backwards, the adjusting block 15 is driven to move backwards synchronously, the adjusting slide block 18 will not move backwards under the action of the first ratchet plate 22, so the energy stored in the power storage spring 16 will not be released. Further, even at the time of a strong wind, the adjusting slider 18 does not move backward, so that the power storage spring 16 is not released.

When the power storage spring 16 is compressed to the limit position, the adjusting slide block 18 moves to the front end of the mounting groove, pushes the fixture block 101 forwards, and enables the fixture block 101 to be separated from a gap between the first expansion plate 17 and the groove wall of the mounting groove, so that the first expansion plate 17 can move left and right.

If the wind power is increased, the first fixing ring 14 can be pulled forwards, the first fixing ring 14 can also be pulled towards the left side surface and the right side surface, and the cable 4 drives the first fixing ring 14 to move left and right through the cable connecting cylinder 5. When the first fixing ring 14 drives the adjusting block 15 to extrude the second expansion plate 19, the fixture block 101 of the adjusting block 15 is separated from the third ratchet plate 24, and then the second expansion plate 19 drives the fixing plate 25 to move rightwards through the plurality of springs when the adjusting block 15 continues to move, the fixing plate 25 drives the adjusting slider 18 and the ratchet bar 21 to move rightwards, so that the second ratchet plate 23 is separated from the first ratchet plate 22, the power storage spring 16 is released, the adjusting slider 18 and the impact rod 6 are pushed to move backwards, when the impact rod 6 has a high speed, the adjusting slider 18 is made to impact the adjusting block 15, then the first fixing ring 14 is made to impact the positioning ring groove on the inner side of the outer adjusting shell 3, until the second one-way bearing is separated from the second fixing ring 10 and moves to the positioning ring, at this time, the cable 4 is released, and the ice and snow on the cable are removed again. At this time, the first fixing ring 14 rotates at the center of the positioning ring groove, and the second one-way bearing rotates relative to the positioning ring in its entirety, so that the resetting is completed.
