Patent publication No. CN102493964A discloses a kind of moving blade regulating device for axial flow fan, comprises worm gear, worm screw, leading screw, nut shaft, tie-plate and tooth bar.When rotary worm, worm gear drives leading screw rotation, and nut shaft moves axially along leading screw, and tie-plate band carry-over bar makes sharf rotation, thereby the variation of the whole blade angles of disposable synchronous realization, can realize after parking and can one subsynchronous vaned institute established angle to be overturn 180 °.The shortcoming of this structure is to realize the adjusting by a small margin of blade angle.
Patent publication No. CN103206392A discloses a kind of adjustable shutter ventilator, comprise air duct, drive motor, impeller, multiple drive motor supporting foots around that are distributed on, one end of supporting foot is fixed on drive motor, the other end is fixed on the base plate of air duct, drive motor is in air duct central authorities, the axis of drive motor and the dead in line of air duct, on the output shaft of drive motor, form multiple grooves, on the sidewall of the center hole of the center fixed block of impeller, form multiple projections, output shaft sleeve is in the center hole of center fixed block, projection sleeve is in groove, center fixed block is bolted to connection the end at output shaft.By fixing bolt is unscrewed, then by blade assembly and fixed plate pull-out, rotor blade assembly, adjust to desired angle, and then coupling shaft is inserted in internal gear piece, external tooth is meshed with the internal tooth of internal gear piece, then by fixing bolt tighten complete adjusting can realize air quantity regulate.The shortcoming of this structure is that loaded down with trivial details, the consuming time length of adjustment process, can not realize quick adjustment.
Summary of the invention
The object of this invention is to provide a kind of movable vane adjustable axial-flow ventilator,
Technology solution of the present invention is as follows: a kind of movable vane adjustable axial-flow ventilator, comprise air duct, drive motor, wheel disc, blade, locking sleeve, cowling, blade is distributed on wheel disc, dunnage is weldingly fixed on air duct inwall, drive motor is fixed in dunnage, drive motor is in air duct central authorities, the axis of drive motor and the dead in line of air duct, wheel disc is fixed on drive motor axle by key, described drive motor is positioned at wheel disc front end, blade pass is crossed nut and is fixed on wheel disc, gear is connected with blade petiole, on locking sleeve, cover has sleeve, sleeve bottom is fixed with tooth bar, this rack and pinion interlock.
Preferably, lobe numbers is greater than three.
Preferably, gear is fixed on blade petiole by key and nut.
Preferably, the tooth bar number of the number of blade of blade, the number of gears of gear, tooth bar, three equates.
Preferably, tooth bar can be fixed on sleeve by the Placement of screw, bolt, welding or riveted joint.
Preferably, described sleeve and locking sleeve are slidably connected.
Beneficial effect of the present invention is: (1) the present invention directly adjusting vane established angle reaches the effect that regulates air quantity, the adjusting of air quantity is become simply, facilitate; (2) stop after without dismounting, only need loose nut, move axially sleeve, and drive the tooth bar that is fixedly connected with it, moving horizontally of tooth bar drives and its meshed gears rotation, thereby change the rotation of the blade bottom petiole being fixedly connected with gear, thereby can complete fast the synchronization regulation of blade angle; (3) the present invention is simple and practical, cheap, has greatly market popularization value.
