In this embodiment, a plurality of matching rods 210 uniformly distributed along the circumferential direction of the ice melting ring 310 are arranged in the outer shell 200; the matching rods 210 are arranged along the ice melting ring 310 in the radial direction, the outer ends of the matching rods are fixed with the outer shell 200, and the inner ends of the matching rods are in sliding fit with the ice melting ring 310 through the annular grooves, so that the ice melting ring 310 can be detached more conveniently.
With the above embodiments, the usage principle and working process of the present invention are as follows: when the ice melting device is used, the motor 520 is started, the motor 520 drives the power cone pulley 510 to rotate, the power cone pulley 510 drives the two driving cone pulleys 530 to rotate in the opposite directions, and the driving cone pulleys 530 drive the corresponding ice melting rings 310 to rotate through the second telescopic rods. On one hand, the first guide wheel 611 is driven to rotate on the surface of the ice layer when the ice melting ring 310 rotates, because an included angle is formed between the axis of the rotating shaft of the first guide wheel 611 and the axis of the power transmission line 100, the ice melting ring 310 moves forward spirally when rotating, and the axis of the rotating shaft of the first guide wheel 611 on the two ice melting rings 310 is symmetrical front and back in the initial state, so that when the ice melting ring 310 moves forward when rotating, the corresponding ice melting rods 320 on the two ice melting rings 310 respectively melt the spiral ice seams 630 with opposite spiral directions when moving forward on the ice layer, thereby dividing the ice layer into a grid shape. When the thickness of the ice layer is increased, the ice layer drives the first guide wheel 611 to drive the ice-melting sliding column to move outwards along the radial direction of the ice-melting ring 310, and under the sliding fit of the ice-melting sliding block and the ice-melting spiral groove 612, the ice-melting sliding column moves outwards and simultaneously drives the first guide wheel 611 to rotate, so that the included angle between the rotating shaft axis of the first guide wheel 611 and the axis of the power transmission line 100 is increased, and the forward movement speed of the ice-melting ring 310 is reduced. When the forward speed of the ice melting ring 310 becomes slow, the ice melting ring 310 drives the pitch of the spiral ice gaps 630 formed by the ice melting rods 320 on the surface of the ice layer to become small. Similarly, when the ice layer becomes thinner, the ice melting ring 310 drives the ice melting rod 320 to melt the spiral ice seam 630 on the surface of the ice layer, and the pitch of the spiral ice seam becomes larger.
On the other hand, the ice melting ring 310 on the rear side drives the ice knocking ring 410 to rotate synchronously through the first telescopic rod. The ice knocking ring 410 is driven to rotate on the surface of an ice layer when rotating, an included angle is formed between the axis of the rotating shaft of the second guide wheel 621 and the axis of the transmission line 100, so that when the thickness of the ice layer is increased, the ice layer drives the second guide wheel 621 to drive the ice knocking sliding column to move outwards along the radial direction of the ice knocking ring 410, the ice knocking sliding block and the ice knocking spiral groove are in sliding fit, the ice knocking sliding column is driven to rotate while moving outwards, the included angle between the axis of the rotating shaft of the second guide wheel 621 and the axis of the transmission line 100 is increased, the forward moving speed of the ice knocking ring 410 is reduced, and the pitch of a track of the ice knocking rod 420 for knocking the ice layer is reduced by the ice knocking ring 410. Similarly, when the ice layer becomes thinner, the pitch of the trajectory of the ice knocking ring 410 driving the ice knocking rod 420 to knock the ice layer becomes larger. Because the axis of the rotating shaft of the second guide wheel 621 is parallel to the axis of the rotating shaft of the first guide wheel 611 on the adjacent ice-melting ring 310 in the initial state, the pitch of the track of the ice-knocking ring 410 driving the ice-knocking rod 420 to knock the ice layer is the same as the pitch of the spiral ice seam 630 formed by the ice-melting ring 310 driving the ice-melting rod 320 to melt on the surface of the ice layer at the same position of the ice layer thickness, that is, the ice-knocking ring 410 driving the ice-knocking rod 420 to knock the ice layer on the ice layer along the spiral ice seam 630. That is, when the ice layer is thicker, the slower the spiral advancing speed of the ice melting ring 310 and the ice knocking ring 410 is, the smaller the pitch of the spiral ice gap 630 is, the smaller the grid into which the ice layer is divided is, the more the ice knocking rod 420 hits the ice layer within the same displacement, when the ice layer is thinner, the faster the spiral advancing speed of the ice melting ring 310 and the ice knocking ring 410 is, the larger the pitch of the spiral ice gap 630 is, the larger the grid into which the ice layer is divided is, the less the ice knocking rod 420 hits the ice layer within the same displacement, the self-adaptive adjustment of the advancing speed on the power transmission line 100 according to the thickness of the ice layer is realized, and the deicing efficiency on the ice layer on the surface of the power transmission line 100 is improved.
Further, when the number of the ice melting rods 320, the number of the ice knocking rods 420 and the number of the guide grooves 430 on each ice melting ring 310 are two, the position where the ice knocking rod 420 strikes the ice layer is located at the intersection point of the two spiral ice gaps 630 with opposite spiral directions, so that the ice removing effect on the ice layer on the transmission line 100 is better.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
