Drawing mechanism is resetted in the present invention and the purpose of design of circumgyration stretch mechanism is to be with two adjacent electric poles Example；Two electric poles are followed successively by the first electric pole and the second electric pole；When covering very thick snow on cable, the first electric pole Cable between the second electric pole drops under the action of accumulated snow gravity；Cable between first electric pole and the second electric pole Both ends pull stretching disk and the second electric wire in the circumgyration stretch mechanism on the first electric pole in the first snow-removing mechanism respectively Stretching disk in circumgyration stretch mechanism on bar in the second snow-removing mechanism slides in opposition along corresponding round through slot.

For the first snow-removing mechanism on the first electric pole, the stretching disk in circumgyration stretch mechanism therein drives guidance It sells inner headed face in spiral chute along round through slot to spin sliding motion, two first reset bullets in the first snow-removing mechanism Spring is stretched simultaneously；Guidance pin drives the stretching disc rotary being attached thereto；Stretching disk in circumgyration stretch mechanism pulls electricity Cable is moved between the first electric pole and the second electric pole；Reset drawing mechanism in stretchings disk overcome limited block limitation and Stretching disk in circumgyration stretch mechanism slides together；At the same time, the stretching disk in circumgyration stretch mechanism drives cable slow Slow rotation.

For the second snow-removing mechanism on the second electric pole, the stretching disk in circumgyration stretch mechanism therein drives guidance It sells inner headed face in spiral chute along round through slot to spin sliding motion, two first reset bullets in the second snow-removing mechanism Spring is stretched simultaneously；Guidance pin drives the stretching disc rotary being attached thereto；Stretching disk in circumgyration stretch mechanism pulls electricity Cable is moved between the first electric pole and the second electric pole；Reset drawing mechanism in stretchings disk overcome limited block limitation and Stretching disk in circumgyration stretch mechanism slides together；At the same time, the stretching disk in circumgyration stretch mechanism drives cable slow Slow rotation；Since the structure of the first snow-removing mechanism on an electric pole and the structure of the second snow-removing mechanism are about electric pole center Face is symmetrical, so stretching the second snow removing on the direction of rotation and the second electric pole of disk on the first electric pole in the first snow-removing mechanism The direction of rotation that disk is stretched in mechanism is consistent.

When most of accumulated snow on cable due to cable rotation and moment fall after, the first snow breaker on the first electric pole Two first back-moving springs in structure stretch disk by two and the limitation of limited block are overcome to pull cable quick to initial position It shrinks and quickly rotates；Two first back-moving springs on second electric pole in the second snow-removing mechanism pass through two stretching disks gram The limitation for taking limited block pulls cable to initial position rapid desufflation and quickly rotates；Remaining residual snow is in rotating centrifugal on cable It is got rid of again under the action of power and falls a part；When the two stretching disks and the second electricity in the first snow-removing mechanism in the first electric pole After two stretching disks in the second snow-removing mechanism in line bar return to respective initial position；Stretch the motional inertia of disk not It is sufficient to make first back-moving spring to be compressed, stretches disk and be temporarily positioned in initial position stopping sliding and rotation；First electric pole And the second cable between electric pole；Shake is continued up under the action of inertia；During cable is shaken upwards, cable The stretching disk at its both ends is pulled to overcome the limitation of corresponding limited block and slide in opposition, the first snow-removing mechanism of the first electric pole In two first back-moving springs and the second electric pole the second snow-removing mechanism in two first back-moving springs be stretched simultaneously； The guidance pin of cable ends drives cable quickly to rotate again；When cable shake is to lowest point, the first electric pole and the second electricity First back-moving spring in line bar drives cable shrinkage by stretching disk accordingly, while being driven and being drawn by guidance pin accordingly Stretch disk reverse rotation；Stretching disk in first electric pole in the first snow-removing mechanism overcomes the limitation of corresponding limited block again Return to initial position；Stretching disk in second electric pole in the second snow-removing mechanism overcomes the limitation of corresponding limited block to return again To initial position；Cable continues to be less than the jitter amplitude of last time and shake；Stop after the shake several times and rotation of cable and so on It only moves and returns to initial position；In the whole process, cable is by first time rotation so that most accumulated snow is fallen, then Cable passes through the reciprocal shake of itself again and quickly rotates and get rid of remaining accumulated snow.

The purpose of design of position-limit mechanism is in the present invention, by taking adjacent the first electric pole and the second electric pole as an example；When two When the accumulated snow on cable between a electric pole reaches certain limit, the gravity of accumulated snow makes the cable between two electric poles Tenesmus, cable pull on stretching disk and the second electric pole on the first electric pole in the first snow-removing mechanism in the second snow-removing mechanism Stretching disk sliding.

For the first snow-removing mechanism on the first electric pole, the tenesmus of the cable between two electric poles is so that wherein reset Stretching disk in drawing mechanism acts on the limit inclined-plane of corresponding limited block, so that limited block moves downward, while second Reset spring is compressed；Limited block releases the limitation to disk is stretched；Cable, which drives, resets drawing mechanism and circumgyration stretch mechanism In stretching disk continue to slide；Stretching disk in circumgyration stretch mechanism is under the action of corresponding guidance pin is with spiral chute Rotation；The rotation of stretching disk in circumgyration stretch mechanism drives electric cable rotary in turn.

For the second snow-removing mechanism on the second electric pole, the tenesmus of the cable between two electric poles is so that wherein reset Stretching disk in drawing mechanism acts on the limit inclined-plane of corresponding limited block, so that limited block moves downward；Limited block solution Except the limitation to disk is stretched, while second back-moving spring is compressed.

Rib during limited block moves downward, below the first notch with the first reseting groove of the lower slideway of friction block Have an effect and be swung up around pin shaft center line, therewith friction block lower slideway swing 45 degree and completely with limiting slot inner wall Contact；Meanwhile scroll spring deforms and reaches maximum and energy storage；Since the lower slideway on friction block is smooth bevel, under The friction very little of slideway and limiting slot inner wall, as long as stretching disk breaches limited block upper limit inclined-plane to the pressure of limited block It is self-locking, then limited block accordingly stretch disk under the action of by sharp downward movement, no longer to reset drawing mechanism in Stretching disk form substantive obstruction；When resetting the stretching disk in drawing mechanism by the top of limited block, limited block Downward movement reach capacity；Friction block enters the second reseting groove, and the lower slideway on friction block is detached from limiting slot inner wall；? Under the action of scroll spring, friction block backswing to initial position；When reset drawing mechanism in stretching disk after limited block, Limited block moves upwards under the action of second back-moving spring；Rib above the upper slideway of friction block and the second reseting groove notch It interacts and around pin shaft central axis to lower swing；As limited block continues up；The upper slideway of friction block is with rubbing Cleaning block swings 45 degree and contacts completely with limiting slot inner wall；At this point, the deformation of scroll spring reaches maximum and energy storage；Due to upper cunning The coefficient of friction on inclined-plane is very big, so the frictional force between friction block and limiting slot inner wall makes in limited block uphill process The rate of climb of limited block is very slow；When the stretching disk in reset drawing mechanism slides to initial position and encounters limited block, The current inclined-plane of the first of limited block and the second current inclined-plane just expose；It resets the stretching disk in drawing mechanism and acts on the Two current inclined-planes, so that limited block moves downward again and releases the limitation to disk is stretched；In the process, since first is logical The gradient on row inclined-plane and the gradient on the second current inclined-plane are easy to dash forward much smaller than the gradient on limit inclined-plane so resetting drawing mechanism The limitation of broken limited block continues to slide；Disk is being stretched to when initial position sliding, limited block is not formed stretching disk substantially It hinders；When resetting top of the stretching disk in drawing mechanism by limited block, limited block is moved downwardly to again the limit, Friction block backswing to initial position, upper slideway is detached from limiting slot inner wall；When in reset drawing mechanism and circumgyration stretch mechanism When two first back-moving springs restore to the original state, stretch disk and cross limited block, limited block under the action of second back-moving spring to Upper movement, the upper slideway on friction block contact with limiting slot inner wall again and generate friction；Cable between two electric poles Shake is continued up under the action of inertia；When cable shake is to certain altitude, cable is pulled again in reset drawing mechanism Disk is stretched along round through slot sliding；At this point, the current inclined-plane of the first of limited block and the second current inclined-plane just expose limiting slot； It resets the stretching disk in drawing mechanism and acts on the first current inclined-plane and cross limited block and continue to slide；In circumgyration stretch mechanism Guidance pin by accordingly stretch disk drive electric cable rotary；It stretches sliding laterally for disk and is necessarily accompanied with rotation；In electricity During the reciprocal shake and rotation of cable, the speed of limited block upward sliding is slow；Whenever the reset in two electric poles is drawn The stretching disk resetted in drawing mechanism when stretching the stretching disk in mechanism and meeting with corresponding limited block, in two electric poles Reciprocally act on the first current inclined-plane and the second current inclined-plane of corresponding limited block；So that limited block is to two electric poles In reset drawing mechanism in reciprocatingly sliding for disk of stretching do not constitute substantial obstacle so that the reciprocal shake of cable It is excessively lasting with rotational energy；When tending to calmness after cable is back and forth shaken several times, the stretching disk and first in two electric poles are multiple Position spring returns to initial position；The second snow removing on limited block and the second electric pole on first electric pole in the first snow-removing mechanism Limited block in mechanism will slide to initial position movement in unobstructed ground under the action of corresponding second back-moving spring；It is limiting During position block moves upwards, the upper slideway on corresponding friction block is released and is rubbed completely with limiting slot inner wall； When limited block moves upward to initial position, the upper slideway of friction block is detached from limiting slot inner wall；In the recovery of scroll spring Under the action of power, friction block backswing to initial position simultaneously enters in the first reseting groove；The limit inclined-plane of limited block is again to reset Stretching disk in drawing mechanism limits and plays self-locking function.

The coefficient of friction of upper slideway is greater than the coefficient of friction of lower slideway in the present invention, the gradient on the first current inclined-plane and The purpose of design that the gradient on the second current inclined-plane is respectively less than the gradient for limiting inclined-plane is, when limited block moves downward, glides oblique Face is contacted with limiting slot inner wall；When limited block moves upwards, upper slideway is contacted with limiting slot inner wall；Upper slideway and limit The frictional force that the frictional force of slot inner wall is greater than lower slideway and limiting slot inner wall is big, is easy upper slide to realize limited block and glide Slow purpose；When the stretching disk resetted in drawing mechanism in the first snow-removing mechanism or the second snow-removing mechanism is in cable The limit inclined-plane of limited block is acted under pulling for the first time, so that limited block glides and releases the sliding to disk is stretched；When When stretching disk reset, the first current inclined-plane and the second current inclined-plane on limited block just expose limiting slot；Disk is stretched to make For the second current inclined-plane, so that limited block moves downward；When cable is shaken downwards and drives the stretching resetted in drawing mechanism Disk acts on the first current inclined-plane of limited block, limits so that limited block moves downward to release the sliding for stretching disk；? During stretching disk in reset drawing mechanism reciprocatingly slides, stretches disk and the first current inclined-plane and the second current inclined-plane is past Multiple effect；Due to the gradient very little on the first current inclined-plane and the second current inclined-plane, limited block to the limitation very little for stretching disk, with Guarantee reciprocatingly sliding not by substantive obstruction for stretching disk.

By taking two adjacent electric poles as an example, two electric poles are followed successively by the first electric pole and the second electric pole；Work as cable On when covering very thick snow, the cable between the first electric pole and the second electric pole drops under the action of accumulated snow gravity；The The both ends of cable between one electric pole and the second electric pole pull the rotation on the first electric pole in the first snow-removing mechanism respectively The stretching disk edge in the circumgyration stretch mechanism stretched on disk and the second electric pole in the second snow-removing mechanism in drawing mechanism Corresponding circle through slot slides in opposition.For the first snow-removing mechanism on the first electric pole, in circumgyration stretch mechanism therein Stretching disk drives inner headed face of the guidance pin in spiral chute along round through slot to spin sliding motion, in the first snow-removing mechanism Two first back-moving springs be stretched simultaneously；Guidance pin drives the stretching disc rotary being attached thereto；In circumgyration stretch mechanism Stretching disk pull cable moved between the first electric pole and the second electric pole；Reset the stretching disk gram in drawing mechanism The limitation for taking limited block is slided together with the stretching disk in circumgyration stretch mechanism；At the same time, the drawing in circumgyration stretch mechanism Stretching disk drives cable slowly to rotate.For the second snow-removing mechanism on the second electric pole, in circumgyration stretch mechanism therein Stretching disk drives inner headed face of the guidance pin in spiral chute along round through slot to spin sliding motion, in the second snow-removing mechanism Two first back-moving springs be stretched simultaneously；Guidance pin drives the stretching disc rotary being attached thereto；In circumgyration stretch mechanism Stretching disk pull cable moved between the first electric pole and the second electric pole；Reset the stretching disk gram in drawing mechanism The limitation for taking limited block is slided together with the stretching disk in circumgyration stretch mechanism；At the same time, the drawing in circumgyration stretch mechanism Stretching disk drives cable slowly to rotate.

Since the structure of the first snow-removing mechanism on an electric pole and the structure of the second snow-removing mechanism are about in electric pole Heart face is symmetrical, so the direction of rotation for stretching disk on the first electric pole in the first snow-removing mechanism is removed on the second electric pole second The direction of rotation that disk is stretched in snow mechanism is consistent；When most of accumulated snow on cable is due to the rotation of cable and moment is fallen Fall behind, two first back-moving springs on the first electric pole in the first snow-removing mechanism overcome limited block by two stretching disks Limitation pulls cable to rotate to initial position rapid desufflation and quickly；Two first on second electric pole in the second snow-removing mechanism Reset spring overcomes the limitation of limited block to pull cable to initial position rapid desufflation and quickly rotates by two stretching disks； Remaining residual snow is got rid of again under the action of rotary centrifugal force on cable falls a part；When the first snow breaker in the first electric pole Two stretching disks in two the second snow-removing mechanisms stretched in disk and the second electric pole in structure return to respective initial Behind position；The motional inertia for stretching disk is compressed insufficient for first back-moving spring, is stretched disk and is temporarily positioned in initial bit Set stopping sliding and rotation；Cable between first electric pole and the second electric pole；Shake is continued up under the action of inertia； During cable is shaken upwards, cable pulls the stretching disk at its both ends to overcome the limitation of corresponding limited block and slide in opposite directions It is dynamic, in the second snow-removing mechanism of two first back-moving springs and the second electric pole in the first snow-removing mechanism of the first electric pole Two first back-moving springs are stretched simultaneously；The guidance pin of cable ends drives cable quickly to rotate again；When cable shake is arrived When lowest point, the first back-moving spring in the first electric pole and the second electric pole drives cable to receive by stretching disk accordingly Contracting, while disk is stretched by guidance pin drive accordingly and is reversely rotated；Stretching in first electric pole in the first snow-removing mechanism Disk overcomes the limitation of corresponding limited block to return to initial position again；Stretching circle in second electric pole in the second snow-removing mechanism Disk overcomes the limitation of corresponding limited block to return to initial position again；Cable continues to be less than the jitter amplitude of last time and shake；Electricity Stop motion and initial position is returned to after cable shake several times and so on and rotation；In the whole process, cable passes through first Secondary rotation is so that most accumulated snow is fallen, and then cable passes through the reciprocal shake of itself again and quickly rotates and get rid of surplus Coproduct snow.

Relative to traditional high-tension bus-bar snow-removing device, covered in the present invention when on the cable between two adjacent electric poles When having covered a large amount of snow, on first electric pole on the first snow-removing mechanism and second electric pole on first electric pole The second adjacent snow-removing mechanism of one snow-removing mechanism makes the cable between two electric poles drop downwards together；Meanwhile cable is sent out Raw rotation；Snow on cable slides from cable because of the rotation of cable；After most snow slides, first electric pole On the first snow-removing mechanism and second electric pole on the second snow-removing mechanism respective two first back-moving springs effect Down while resetting；So that the cable between two electric poles is moved to original state rapidly；Electricity between two electric poles Cable moment obtains certain acceleration；Under the action of inertia, cable continues up；Then it falls again；Cable goes out Now shake up and down reciprocatingly, so that the accumulated snow on cable slides；Meanwhile the shake of cable also drive the first snow-removing mechanism and Stretching disk transverse reciprocating in second snow-removing mechanism is slided and is rotated；Cable continues to generate reciprocating rotary, so that on cable Accumulated snow is further fallen under the influence of centrifugal force；The shake of cable and the reciprocating rotary of cable remove cable to the maximum extent The accumulated snow fallen thereon reaches preferably snow removing purpose, provides reliable guarantee for the power Transmission in cold season, saves A large amount of human cost；The configuration of the present invention is simple has preferable using effect.

21 band of stretching disk for the second snow-removing mechanism 5 on the second electric pole 1, in circumgyration stretch mechanism 25 therein Dynamic guidance pin 23 is spinned sliding motion in spiral chute 8 along the inner headed face of round through slot 7, and two in the second snow-removing mechanism 5 A first back-moving spring 22 is stretched simultaneously；Guidance pin 23 drives the stretching disk 21 being attached thereto to rotate；Circumgyration stretch mechanism Stretching disk 21 in 25 pulls cable 3 to move between the first electric pole 1 and the second electric pole 1；It resets in drawing mechanism 24 Stretching disk 21 overcome the limitation of limited block 26 to slide together with the stretching disk 21 in circumgyration stretch mechanism 25；It is same with this When, the stretching disk 21 in circumgyration stretch mechanism 25 drives cable 3 slowly to rotate；Due to the first snow removing on an electric pole 1 The structure of mechanism 4 and the structure of the second snow-removing mechanism 5 are symmetrical about 1 median plane of electric pole, so first removing on the first electric pole 1 Avenge the rotation side for stretching disk 21 on the direction of rotation and the second electric pole 1 that stretch disk 21 in mechanism 4 in the second snow-removing mechanism 5 To being consistent.

When most of accumulated snow on cable 3 due to cable 3 rotation and moment fall after, first removes on the first electric pole 1 Snow mechanism 4 in two first back-moving springs 22 by two stretch disks 21 overcome limited block 26 limitation pull cable 3 to Initial position rapid desufflation simultaneously quickly rotates；Two first back-moving springs 22 on second electric pole 1 in second snow-removing mechanism 5 are logical Crossing two stretching disks 21 overcomes the limitation of limited block 26 to pull cable 3 to initial position rapid desufflation and quickly rotate；Cable 3 Upper remaining residual snow is got rid of again under the action of rotary centrifugal force falls a part；When the first snow-removing mechanism 4 in the first electric pole 1 In two the second snow-removing mechanisms 5 stretched in disks 21 and the second electric pole 1 in two stretching disks 21 return to it is respective After initial position；The motional inertia for stretching disk 21 is compressed insufficient for first back-moving spring 22, and it is temporary to stretch disk 21 Stop sliding and rotation positioned at initial position；Cable 3 between first electric pole 1 and the second electric pole 1；Under the action of inertia Continue up shake；During cable 3 upwards shake, cable 3 pulls the stretching disk 21 at its both ends to overcome corresponding limit Position block 26 limitation and slide in opposition, two first back-moving springs 22 and second in the first snow-removing mechanism 4 of the first electric pole 1 Two first back-moving springs 22 in second snow-removing mechanism 5 of electric pole 1 are stretched simultaneously；The guidance pin 23 at 3 both ends of cable is again The secondary quickly rotation of drive cable 3；When lowest point is arrived in the shake of cable 3, first in the first electric pole 1 and the second electric pole 1 is multiple Position spring 22 drives cable 3 to shrink by stretching disk 21 accordingly, while being driven by guidance pin 23 accordingly and stretching disk 21 reversely rotate；Stretching disk 21 in first electric pole 1 in first snow-removing mechanism 4 overcomes the limit of corresponding limited block 26 again System returns to initial position；Stretching disk 21 in second electric pole 1 in second snow-removing mechanism 5 overcomes corresponding limited block 26 again Limitation return to initial position；Cable 3 continues to be less than the jitter amplitude of last time and shake；The shake several times of cable 3 and so on With stop motion after rotation and return to initial position；In the whole process, cable 3 is by rotation for the first time so that most product Snow is fallen, and then cable 3 is shaken off by the reciprocal shake of itself and quickly rotation again and gets rid of remaining accumulated snow.

The purpose of design of position-limit mechanism 44 is in the present invention, by taking adjacent the first electric pole 1 and the second electric pole 1 as an example； When the accumulated snow on the cable 3 between two electric poles 1 reaches certain limit, the gravity of accumulated snow make two electric poles 1 it Between cable 3 drop, cable 3 pulls the stretching disk 21 and the second electric pole 1 on the first electric pole 1 in first snow-removing mechanism 4 Stretching disk 21 in upper second snow-removing mechanism 5 slides.

For the first snow-removing mechanism 4 on the first electric pole 1, the tenesmus of the cable 3 between two electric poles 1 is so that wherein The limit inclined-plane 28 that the stretching disk 21 in drawing mechanism 24 acts on corresponding limited block 26 is resetted, so that limited block 26 is downward Movement, while second back-moving spring 43 is compressed；Limited block 26 releases the limitation to disk 21 is stretched；Cable 3 drives to reset and draw The stretching disk 21 stretched in mechanism 24 and circumgyration stretch mechanism 25 continues to slide；Stretching disk 21 in circumgyration stretch mechanism 25 exists It is rotated under the action of corresponding guidance pin 23 and spiral chute 8；The anti-mistake of rotation of stretching disk 21 in circumgyration stretch mechanism 25 To drive cable 3 to rotate.

For the second snow-removing mechanism 5 on the second electric pole 1, the tenesmus of the cable 3 between two electric poles 1 is so that wherein The limit inclined-plane 28 that the stretching disk 21 in drawing mechanism 24 acts on corresponding limited block 26 is resetted, so that limited block 26 is downward Movement；Limited block 26 releases the limitation to disk 21 is stretched, while second back-moving spring 43 is compressed.

During limited block 26 moves downward, the lower slideway 39 of friction block is first and under the notch of the first reseting groove 10 Side rib have an effect and be swung up around 41 center line of pin shaft, therewith friction block lower slideway 39 swing 45 degree and completely with The contact of 9 inner wall of limiting slot；Meanwhile scroll spring 42 deforms and reaches maximum and energy storage；Due to the lower slideway on friction block 39 be smooth bevel, the friction very little of lower slideway 39 and 9 inner wall of limiting slot, as long as stretching disk 21 to the pressure of limited block 26 The self-locking of 26 upper limit inclined-plane 28 of limited block is breached, then limited block 26 will be quick under the action of stretching disk 21 accordingly It moves downward, no longer forms substantive obstruction to the stretching disk 21 resetted in drawing mechanism 24；When reset drawing mechanism 24 In stretching disk 21 by 26 top of limited block when, the downward movement of limited block 26 reaches capacity；Friction block enters second Reseting groove 11, the lower slideway 39 on friction block are detached from 9 inner wall of limiting slot；Under the action of scroll spring 42, friction block backswing To initial position；When resetting the stretching disk 21 in drawing mechanism 24 after limited block 26, limited block 26 resets bullet second It is moved upwards under the action of spring 43；Above 11 notch of upper slideway 38 and the second reseting groove of friction block rib interaction and around 41 central axis of pin shaft is to lower swing；As limited block 26 continues up；The upper slideway 38 of friction block is put with friction block It moves 45 degree and is contacted completely with 9 inner wall of limiting slot；At this point, the deformation of scroll spring 42 reaches maximum and energy storage；Since upper cunning is oblique The coefficient of friction in face 38 is very big, so the frictional force between 9 inner wall of friction block and limiting slot makes in 26 uphill process of limited block The rate of climb for obtaining limited block 26 is very slow；When the stretching disk 21 in reset drawing mechanism 24 is slided to initial position and encounters limit When the block 26 of position, the current inclined-plane 29 of the first of limited block 26 and the second current inclined-plane 30 just expose；It resets in drawing mechanism 24 Stretching disk 21 act on the second current inclined-plane 30 so that limited block 26 is moved downward again and is released to stretching disk 21 Limitation；In the process, since the gradient on the first current inclined-plane 29 and the gradient on the second current inclined-plane 30 are much smaller than limit inclined-plane 28 gradient, so the limitation that reset drawing mechanism 24 is easy to break through limited block 26 continues to slide；Disk 21 is being stretched to first When beginning position is slided, limited block 26 is not formed stretching disk 21 substantially to be hindered；Stretching disk in reset drawing mechanism 24 When the top of 21 process limited blocks 26, limited block 26 is moved downwardly to again the limit, friction block backswing to initial position, upper cunning Inclined-plane 38 is detached from 9 inner wall of limiting slot；Two first back-moving springs 22 in reset drawing mechanism 24 and circumgyration stretch mechanism 25 When reinstatement, stretches disk 21 and cross limited block 26, limited block 26 is moved upwards under the action of second back-moving spring 43, rubbed Upper slideway 38 in cleaning block contacts with 9 inner wall of limiting slot again and generates friction；Cable 3 between two electric poles 1 is used Shake is continued up under the action of property；When certain altitude is arrived in the shake of cable 3, cable 3 pulls again to be resetted in drawing mechanism 24 Disk 21 is stretched to slide along round through slot 7；At this point, the current inclined-plane 29 of the first of limited block 26 and the second current inclined-plane 30 just reveal Limiting slot 9 out；The stretching disk 21 in drawing mechanism 24 is resetted to act on the first current inclined-plane 29 and cross the continuation of limited block 26 Sliding；Guidance pin 23 in circumgyration stretch mechanism 25 drives cable 3 to rotate by stretching disk 21 accordingly；Stretch disk 21 It slides laterally and is necessarily accompanied with rotation；During the reciprocal shake and rotation of cable 3, the speed of 26 upward sliding of limited block Slowly；When the stretching disk 21 in the reset drawing mechanism 24 in two electric poles 1 meets with corresponding limited block 26, two The first passage that the stretching disk 21 in reset drawing mechanism 24 in a electric pole 1 reciprocally acts on corresponding limited block 26 is oblique Face 29 and the second current inclined-plane 30；So that limited block 26 is to the stretching resetted in drawing mechanism 24 in two electric poles 1 Reciprocatingly sliding for disk 21 does not constitute substantial obstacle, so that the reciprocal shake of cable 3 and rotational energy are excessively lasting；Work as cable When tending to calmness after 3 reciprocal shakes several times, stretching disk 21 and first back-moving spring 22 in two electric poles 1 return to initial bit It sets；The limit in the second snow-removing mechanism 5 on limited block 26 and the second electric pole 1 on first electric pole 1 in first snow-removing mechanism 4 Position block 26 will slide to initial position movement in unobstructed ground under the action of corresponding second back-moving spring 43；In limited block 26 During moving upwards, the upper slideway 38 on corresponding friction block is released and is rubbed completely with 9 inner wall of limiting slot；When When limited block 26 moves upward to initial position, the upper slideway 38 of friction block is detached from 9 inner wall of limiting slot；In scroll spring 42 Under the action of restoring force, friction block backswing to initial position simultaneously enters in the first reseting groove 10；The limit inclined-plane 28 of limited block 26 Again the stretching disk 21 resetted in drawing mechanism 24 is limited and plays self-locking function.

The coefficient of friction of upper slideway 38 is greater than the coefficient of friction of lower slideway 39 in the present invention, the first current inclined-plane 29 The purpose of design that gradient and the gradient on the second current inclined-plane 30 are respectively less than the gradient for limiting inclined-plane 28 is, when limited block 26 is transported downwards When dynamic, lower slideway 39 is contacted with 9 inner wall of limiting slot；When limited block 26 moves upwards, upper slideway 38 and 9 inner wall of limiting slot Contact；The frictional force that the frictional force of upper slideway 38 and 9 inner wall of limiting slot is greater than lower slideway 39 and 9 inner wall of limiting slot is big, from And it realizes the downslide of limited block 26 and is easy upper sliding slow purpose；When answering in the first snow-removing mechanism 4 or the second snow-removing mechanism 5 Stretching disk 21 in the drawing mechanism 24 of position acts on the limit inclined-plane 28 of limited block 26 for the first time under the pulling of cable 3, thus So that limited block 26 glides and releases the sliding to disk 21 is stretched；When stretching disk 21 and resetting, on limited block 26 first Current inclined-plane 29 and the second current inclined-plane 30 just expose limiting slot 9；It stretches disk 21 and acts on the second current inclined-plane 30, so that Limited block 26 moves downward；When cable 3 is shaken downwards and the stretching disk 21 in reset drawing mechanism 24 is driven to act on limit The current inclined-plane 29 of the first of block 26 limits the sliding for stretching disk 21 so that limited block 26 moves downward to release；It is drawn resetting It stretches during the stretching disk 21 in mechanism 24 reciprocatingly slides, stretches disk 21 and the first current inclined-plane 29 and the second passage inclined-plane 30 reciprocatings；Due to the gradient very little on the first current inclined-plane 29 and the second current inclined-plane 30,26 pairs of stretching disks 21 of limited block Limitation very little, to guarantee to stretch the reciprocatingly sliding not by substantive obstruction of disk 21.

Specific embodiment: by taking two adjacent electric poles 1 as an example, two electric poles 1 are followed successively by the first electric pole 1 and Two electric poles 1.
