bevel gear rotation；First bevel gear is flexible interior by second bevel gear, the first flexible housing and first Bar drives partial gear rotation；At this point, centrifugal force caused by the tooth block in centrifugal wheel is insufficient due to the effect of limit spring So that tooth block slides in and out along limiting slot；Centrifugal wheel does not interact with the first rack gear；First rack gear will not be along first Ladder chute slide downward；First rack gear will not drive partial gear by positioning plate, positioning ring and the first flexible interior bar It moves downward；Partial gear will not interact with the second rack gear；Second rack gear will not be along the second ladder chute and The sliding of three ladder chutes；The joining rod connecting with the second rack gear does not move；Pass through the second flexible housing, the second flexible interior bar It is not moved with the dedusting item that briquetting is connect with joining rod；Dedusting item does not play the effect of dedusting；It is driven when the wind of high speed pushes When dynamic fan rotation, driving fan drives centrifugal wheel and first bevel gear simultaneously and rapidly to rotate by transmission shaft；Positioned at centrifugal wheel On limiting slot in tooth block slid in and out under the influence of centrifugal force along limiting slot, limit spring is stretched；Centrifugal wheel is certainly A gear is formed during turning and is meshed with the first rack gear；The rotation of centrifugal wheel drives the first rack gear trapezoidal along first Sliding slot slide downward；First rack gear drives the first flexible interior bar in the first flexible housing to downslide by positioning plate and positioning ring It is dynamic；Meanwhile first bevel gear drives the first flexible interior bar rotation by second bevel gear and the first flexible housing；First is flexible interior While bar drives partial gear to move downward and rotate；Partial gear interacts with the second rack gear；Second tooth Item is slided along third ladder chute and the second ladder chute；Second rack gear is stretched interior by joining rod, the second flexible housing, second Bar and briquetting drive dedusting item to slide along lampshade bottom；The sliding of dedusting item has blown the dust of lampshade inner wall bottom off；It is same with this When, one end of dedusting item and the generation of wave rack gear act on, and wave rack gear and third reset spring make dedusting item along lampshade bottom It realizes and swings while portion's linear slide；So that dedusting item is more thorough to the dust cleaning in lampshade, reach preferably clear Except the purpose of dust；Since the periphery of partial gear has the teeth of 270 °~320 ° radians, so working as partial gear During rotation is turned around, after the teeth effect on the second rack gear and partial gear, the second rack gear and partial gear It is not acted in generation, the second rack gear moment under the action of second back-moving spring returns to initial position；In the mistake that dedusting item resets Cheng Zhong, under second back-moving spring and the collective effect of wave rack gear, dedusting item is along lampshade bottom linear slide and swings； The secondary of lampshade is cleared up again to realize in dedusting reseting procedure；When centrifugal wheel drives the first rack gear to be moved downwardly to pole When extreme position, first back-moving spring is stretched to extreme position, and entire second rack gear is crossed centrifugal wheel and no longer occurred with centrifugal wheel Effect, the second rack gear do not continue to move downward；At this point, centrifugal wheel just has rotated a circle, partial gear and the second rack gear Disengaging no longer interacts, and the second rack gear and dedusting item are eventually returned to initial position under the action of second back-moving spring, Dedusting item no longer reciprocatingly slides along lampshade inner wall bottom, and dust removal process terminates；Due to first bevel gear and second bevel gear Transmission ratio be 1:4, when centrifugal wheel and first bevel gear synchronous rotary one enclose, second bevel gear passes through flexible housing and first Flexible interior bar drives four circle of partial gear rotation；It is back and forth slided to ensure that dedusting item forms four times under the action of the forces of the wind It is dynamic, realize reciprocal four cleaning of the dedusting item to lampshade；When the speed of wind slows down gradually, partial gear continues to rotate, Tooth block in centrifugal wheel is shunk under the action of limit spring into limiting slot；Tooth block releases the limitation to the first rack gear；First Rack gear moves upwards along the first ladder chute under the action of first back-moving spring and returns to initial position；First rack gear passes through positioning Plate, positioning ring and the first flexible interior bar drive partial gear to move upwards and interact with the second rack gear；Not exclusively Gear drives dedusting item sliding along lampshade bottom by the second rack gear, joining rod, the second flexible housing, the second flexible interior bar and briquetting It is dynamic；Dedusting item swings under the action of wave rack gear；When dedusting item slides four times back and forth under the action of partial gear Afterwards, partial gear is detached from the second rack gear；Dedusting item is eventually returned to initial position under the action of second back-moving spring；In lampshade The dust that dedusting item takes up is fanned by dust discharge through convergence hole and excludes lampshade；Until the speed of wind slows down gradually and stops；Driving fan It stops rotating；Centrifugal wheel, first bevel gear, second bevel gear and partial gear stop rotating.

When the speed of wind is smaller, driving fan drives centrifugal wheel and first bevel gear to rotate by transmission shaft；First Bevel gear drives partial gear rotation by second bevel gear, the first flexible housing and the first flexible interior bar；At this point, due to limit The effect of position spring, centrifugal force caused by the tooth block in centrifugal wheel slide in and out insufficient for tooth block along limiting slot；Centrifugation Wheel does not interact with the first rack gear；First rack gear will not be along the first ladder chute slide downward；First rack gear will not lead to Crossing positioning plate, positioning ring and the first flexible interior bar does not drive partial gear to move downward；Partial gear will not be with the second tooth Item interacts；Second rack gear will not be slided along the second ladder chute and third ladder chute；It is connect with the second rack gear Joining rod does not move；It is not sent out by the dedusting item that the second flexible housing, the second flexible interior bar and briquetting are connect with joining rod Raw movement；Dedusting item does not play the effect of dedusting.

When the wind of high speed pushes driving fan rotation, driving fan drives centrifugal wheel and first bevel gear by transmission shaft Simultaneously and rapidly rotate；Tooth block in the limiting slot on centrifugal wheel slides in and out along limiting slot under the influence of centrifugal force, limit Position spring is stretched；Centrifugal wheel forms a gear during rotation and is meshed with the first rack gear；The rotation of centrifugal wheel Drive the first rack gear along the first ladder chute slide downward；First rack gear is flexible interior by positioning plate and positioning ring drive first Bar slide downward in the first flexible housing；Meanwhile first bevel gear drives the by second bevel gear and the first flexible housing One flexible interior bar rotation；While first flexible interior bar drives partial gear to move downward and rotate；Partial gear and Two rack gears interact；Second rack gear is slided along third ladder chute and the second ladder chute；Second rack gear passes through linking Bar, the second flexible housing, the second flexible interior bar and briquetting drive dedusting item to slide along lampshade bottom；The sliding of dedusting item is blown off The dust of lampshade inner wall bottom；At the same time, one end of dedusting item and the generation of wave rack gear act on, and wave rack gear and third reset Spring realizes dedusting item while along lampshade bottom linear slide to swing；So that dedusting item is to the dust in lampshade Cleaning is more thorough, achievees the purpose that preferably to remove dust；Since the periphery of partial gear has 270 °~320 ° radians Teeth, so when partial gear rotation turn around during, the second rack gear on partial gear teeth act on terminate Afterwards, the second rack gear and partial gear are not acted in generation, and the second rack gear moment under the action of second back-moving spring returns to just Beginning position；During dedusting item resets, under second back-moving spring and the collective effect of wave rack gear, dedusting item is along lampshade Bottom linear slide simultaneously swings；The secondary of lampshade is cleared up again to realize in dedusting reseting procedure；Work as centrifugal wheel When the first rack gear being driven to be moved downwardly to extreme position, first back-moving spring is stretched to extreme position, and entire second rack gear is got over It crosses centrifugal wheel no longer to have an effect with centrifugal wheel, the second rack gear does not continue to move downward；At this point, centrifugal wheel just has rotated one Circle, partial gear no longer interact with the disengaging of the second rack gear, and the second rack gear and dedusting item are in second back-moving spring Initial position is eventually returned under effect, dedusting item no longer reciprocatingly slides along lampshade inner wall bottom, and dust removal process terminates；Due to The transmission ratio of first bevel gear and second bevel gear is 1:4, when centrifugal wheel and the circle of first bevel gear synchronous rotary one, the second cone Gear drives four circle of partial gear rotation by flexible housing and the first flexible interior bar；To ensure that dedusting item in wind-force Lower formed four times of effect reciprocatingly slides；Dedusting item is initial to stopping returning to after reciprocal four cleanings of lampshade in short temporal duration Position stop motion avoids influence of the reciprocating motion of dedusting item to street lamp light, ensure that the illuminating effect of street lamp not by It influences.

When the speed of wind slows down gradually, partial gear continues to rotate, work of the tooth block in centrifugal wheel in limit spring It is shunk with lower into limiting slot；Tooth block releases the limitation to the first rack gear；First rack gear edge under the action of first back-moving spring First ladder chute, which moves upwards, returns to initial position；First rack gear is driven by positioning plate, positioning ring and the first flexible interior bar Partial gear is moved upwards and is interacted with the second rack gear；Partial gear passes through the second rack gear, joining rod, second Flexible housing, the second flexible interior bar and briquetting drive dedusting item to slide along lampshade bottom；Dedusting item is under the action of wave rack gear It swings；After dedusting item slides four times under the action of partial gear back and forth, partial gear is detached from the second rack gear；It removes Dirt item is eventually returned to initial position under the action of second back-moving spring；The dust that dedusting item takes up in lampshade is arranged through convergence hole Dirt fan excludes lampshade；Until the speed of wind slows down gradually and stops；Driving fan is stopped rotating；Centrifugal wheel, first bevel gear, Two bevel gears and partial gear stop rotating；To cleaning again so that the illuminating effect of street lamp is more preferable for lampshade.

Relative to traditional street lamp, street lamp is realized using wind energy automatic dust removing in the present invention, greatly reduces street lamp dimension The cost of shield；It does not need to repair at the top of worker's climbing to lamp stand, avoids what maintenance personal may occur because of ascending a height It is dangerous；Centrifugal wheel can identify wind speed size, if wind speed is smaller, centrifugal wheel does not interact with the first rack gear, dedusting Item does not move, and dedusting item does not play dustproof function；If wind speed is very big, centrifugal wheel interacts with the first rack gear, So that dedusting item is in lampshade by reciprocal four times movements, cleaning of the completion to lampshade inner wall；When wind speed slows down, incomplete tooth During wheel resets, dedusting item carries out primary reciprocal cleaning to lampshade again, so that the dust removing effects of lampshade are more preferable；Dedusting item It swings while under the second rack drives along lampshade inner wall basal sliding, so that dust more obstinate in lampshade obtains Cleaning, so that the dust removing effects in lampshade reach dust removal requirement to the maximum extent, using effect of the lampshade again after dedusting is more preferable；This Inventive structure is simple, has preferable using effect.
