When needing to divulging information in tunnel, pushing block 53 is pushed, the driven spur gear 18 of high speed is driven by catch bar 65, is moved
Dynamic connecting shaft 19 is slided with the driven spur gear 21 of low speed, when the driven spur gear 21 of low speed is engaged with low speed active spur gear 17,
Upper card slot 68 is right against fixture block 75, and then 75 left end of fixture block enters in upper card slot 68 and blocks catch bar 65 under the effect of 74 elastic force,
The driven spur gear 18 of high speed does not engage with high speed active spur gear 15 at this time, starts motor 12 at this time, and then pass through motor shaft 13
It drives high speed active spur gear 15 to rotate, and then drives low speed active spur gear 17 to rotate by fixed connection shaft 16, Jin Ertong
It crosses between low speed active spur gear 17 and the driven spur gear 21 of low speed and engages the driven rotation of spur gear 21 of mating connection drive low speed,
And then deceleration active spur gear 25 is driven to rotate by sliding axle 22, and then straight with reduction driven by deceleration active spur gear 25
Engagement, which is cooperatively connected, between gear 26 drives 26 underdrive of reduction driven spur gear, and then is driven and turned to by low speed shaft 27
Drive bevel gear 30 rotates, and then engages mating connection band between drive bevel gear 30 and steering driven wheel of differential 31 by turning to
Turn is rotated to driven wheel of differential 31, and then long shaft 35 is driven to rotate, and then driving pulley 36 is driven to rotate, and then by same
Walking band 37 drives driven pulley 39 to rotate, and then drives the rotation of rotor 54 to drive fan by fixed block 62 by rotation axis 41
Rachis 51 rotates, and then flabellum 52 is driven to rotate, and at this time to being aerated in tunnel, while passing through long shaft 35 drive differential master
Dynamic spur gear 43 rotates, and then drives transmitting tooth by engaging mating connection between differential active spur gear 43 and transmission gear 44
44 rotation of wheel, and then the driven straight-tooth of differential is driven by engaging mating connection between transmission gear 44 and the driven spur gear 45 of differential
45 underdrives are taken turns, and then drives and turns to the rotation of shaft 50, and then mounting blocks 56 is driven to rotate, due to turning to shaft 50 and rotating
There are rotational speed differences between axis 41, therefore there are rotational speed differences between mounting blocks 56 and rotor 54, between contact block 57 and steering block 59
There are rotational speed difference, and then the promotion steering block 59 that contact block 57 is irregular, and then the irregular rotation of flabellum axle 51 is driven, and then band
The dynamic irregular rotation of flabellum 52 generates irregular wind direction, revolution can be driven so that steering block 59 with flabellum axle 51 by torsional spring 64
Again it offsets with contact block 57, when generation wind speed is too small, stops motor 12, pull block 82, and then pass through 79 band of bracing wire
Dynamic fixture block 75 slips away upper card slot 68, continues to press on pushing block 53, makes high speed active spur gear 15 and high speed by catch bar 65
Driven spur gear 18 is meshed, and the spur gear of low speed active at this time 17 is disengaged from the driven spur gear 21 of low speed, at this time lower bayonet slot
67 are right against fixture block 75, and 75 left end of fixture block, which enters in lower bayonet slot 67, blocks catch bar 65, start motor 12, the wind speed of generation at this time
Increase.
The beneficial effects of the present invention are: the configuration of the present invention is simple, easy to operate, and when needing to divulging information in tunnel, selection
Starter after wind speed reduces revolving speed by deceleration device, while driving rotational structure and steering structure, and rotational structure drives wind
Fan structure rotation and to being aerated in tunnel, while steering structure slows down by second and generates rotational speed difference with rotational structure,
And control flabellum direction and can change wind direction, make to generate irregular wind in tunnel, apparatus of the present invention are not only able to manually adjust
