The principle of the invention is as follows:
when the automatic dust removing device is used, by arranging the offset wheel 14, the linkage mechanism 22, the pull rope 33, the moving frame 34 and the butt plate 35, when the asynchronous motor 2 is started, the output shaft of the asynchronous motor 2 drives the offset wheel 14 to rotate, because the offset wheel 14 rotates in an oval shape, the offset wheel 14 pushes the two rolling balls 29 with the left side wall surface and the right side wall surface mutually attached back and forth on the motor box 1, the two rolling balls 29 moving left and right on the motor box 1 drive the two corresponding pushing frames 27 to move synchronously, the two pushing frames 27 drive the corresponding pull rope 33 to alternately pull the two moving frames 34 to move up and down in the butt groove 36, at the moment, the two moving frames 34 moving up and down back and forth drive the two corresponding groups of cleaning rings 40 to move up and down in a staggered manner, through the different rotating speeds of the asynchronous motor 2, the two groups of cleaning rings 40 indirectly wipe up and down with the outer cylindrical wall surface of the asynchronous motor 2 back and forth, and dust outside the asynchronous motor 2 is automatically removed, simultaneously when corresponding butt plate 35 from up removing down, correspond two 38 springs of butt plate 35 and correspond a set of clearance ring 40 owing to the elasticity deformation of self and remove with higher speed, upwards remove with higher speed clearance ring 40 can clear up the adnexed stubborn dust that adheres to asynchronous machine 2 outer wall, improve the dust removal to asynchronous machine 2.
By arranging the push rod 26, the sleeve ring 25, the first rolling ball 23 and the extruding device 30, when the rotating deflection pulley 14 drives the corresponding second rolling ball 29 to move towards the direction of the adjusting block 19, in the process, the second rolling ball 29 pushes the push rod 26 through the pushing frame 27 to drive the first rolling ball 23 to move upwards along the inclined plane in the adjusting groove 20, at the moment, the first rolling ball 23 drives the roller first 24 to extrude the bouncing ball 31 and the spring first 32, at the moment, the spring first 32 is continuously contracted to generate elastic deformation, when the other side of the rotation of the deflection pulley 14 is rotated, the second rolling ball 29 rolls towards the direction far away from the adjusting block 19, at the moment, the spring first 32 recovers the elastic deformation and accelerates the pushing frame 27 to move towards the output shaft direction of the asynchronous motor 2 together with the downward rolling inertia of the first rolling ball 23 in the adjusting groove 20 due to the self gravity, at the moment, the accelerating movement of the pushing frame 27 accelerates to pull the pull rope 33 downwards, the accelerating downward pull rope 33 drives the corresponding cleaning ring 40 to rapidly wipe the outer wall surface of the asynchronous motor 2 downwards, improve the promotion effect to asynchronous machine 2's outer wall cleaning strength, grounder 23 drives the inside air of adjustment tank 20 and flows downwards in the inside downstream of adjustment tank 20 simultaneously with higher speed, and the inside air that flows of adjustment tank 20 is the dust that drops with higher speed motor case 1 inside wall downwards quick landing, and the dust of landing is to the inside of the 6 discharge motor casees of air vent 6, plays the guide to the dust of the inside whereabouts of motor case 1 downwards.
When the asynchronous motor 2 is started to drive the fan blade 3 to rotate, when the fan blade 3 drives the two lower side plates 4 and the two upper side plates 8 to vertically correspond to each other, the distance between the first magnetic sheet 5 and the second magnetic sheet 11 is closest, the repulsion force of the first magnetic sheet 5 to the second magnetic sheet 11 is the largest, the repulsion force of the first magnetic sheet 5 to the second magnetic sheet 11 drives the guide plate 10 to violently move upwards in an accelerating manner, the guide plate 10 drives the guide rod 12 to move upwards, the two guide rods 12 drive the dredging needle plate 13 and the air outlet holes 6 to mutually approach each other, when the dredging needle plate 13 moves upwards to the highest position, the cylindrical needle of the dredging needle plate 13 is extruded into the corresponding air outlet holes 6, and when the lower side plates 4 and the upper side plates 8 are far away from each other, the dredging needle plate 13 drives the first magnetic sheet 5 to upwards exert the repulsion force of the second magnetic sheets 11, dredge faller 13 and do free fall downstream this moment, when lower plate 4 has once more removed under 8 side plates again, dredge faller 13 rebound again, along with the continuous rotation of flabellum 3, the cylinder needle of dredge faller 13 constantly dredges the effect to 6 insides of venthole, and the inside condition that has the dust granule to block up of prevention venthole 6 takes place.
Be provided with downside board 4 simultaneously, magnetic sheet one 5, venthole 6, dust discharging device 7, guide board 10, magnetic sheet two 11, guide rod 12 and mediation faller 13, keep away from with upside board 8 each other along with flabellum 3 is rotatory constantly when magnetic sheet one 5, repulsive force and magnetic sheet two 11 of magnetic sheet one 5 pair magnetic sheet two 11, gravity alternates each other downwards between guide rod 12 and the mediation faller 13, guide board 10 constantly reciprocates in the inside of guide chamber 9 this moment, guide board 10 has constantly reciprocated in guide chamber 9 inside and has played similar air exhauster effect, guide board 10 that reciprocates is guiding chamber 9 inside air flow with higher speed, guide board 10 discharges from venthole 6 at the inside heat of guide chamber 9 inside constantly downward movement acceleration motor case 1 simultaneously, play the promotion to 2 inside heat dissipations of asynchronous machine.
When being provided with inlet port 15 and filter screen 16 simultaneously, when outside air flows into motor case 1 inside from inlet port 15, the inside filter screen 16 of inlet port 15 has played preliminary interception effect to the dust granule in the outside air, simultaneously when outside dust granule is blocked by filter screen 16, the dust granule that is blocked has played good interception effect to outside dust granule because self gravity and the inclined plane of inlet port 15 slide down, the trapezoidal internal channel of two inlet ports 15 simultaneously, when outside cold air gets into motor case 1 inside from inlet port 15, because the internal channel of inlet port 15 narrows down gradually, according to the narrow tube effect, the cold air that flows into motor case 1 inside is compressed and is accelerated motion, play the promotion to motor case 1 inside heat dissipation.
By arranging the moving frame 34, the vibrating brush 39, the spring two 38, the linkage mechanism 22, the pull rope 33 and the offset wheel 14, when the output shaft of the asynchronous motor 2 drives the offset wheel 14 to rotate, the offset wheel 14 drives the rolling balls two 29 on the left and right linkage mechanisms 22 to roll back and forth, the rolling balls two 29 which roll back and forth drive the push frame 27 to pull the moving frame 34 back and forth to swing up and down on the butt plate 35, the up and down swinging butt plate 35 drives the corresponding vibrating brush 39 and two filter screens 16 to rub against each other, when the moving frame 34 moves up, the spring two 38 promotes the sliding friction between the vibrating brush 39 and the filter screens 16 through automatic elastic deformation, the mutual friction between the vibrating brush 39 and the filter screens 16 does not influence the external compressed cold air to enter the asynchronous motor 2, and the vibrating brush 39 continuously conducts the filter holes of the filter screens 16, thereby avoiding the occurrence of the condition that the external dust is attached to the filter screens 16 to block and the flow rate of the cold air flowing into the asynchronous motor 2 is reduced, the automatic dust cleaning is also performed on the filter screen 16.
Through being provided with clearance ring 40, when motor case 1 is inside to be overhauld and maintain, can take out motor case 1 from indoor top through the rotatory fastener on the clearance ring 40 of instruments such as screwdrivers, simple structure, the dismouting is convenient.
