Abstract
The present invention relates to a kind of water generating impeller, including impeller axle and impeller blade, pass through the shape to impeller blade, reduction of speed plate and the setting except dry part, do not shaken so that the water conservancy generator impeller is stable in rotation process, and stabilization of speed, so that the collision between impeller axle and bearing, axle and axle greatly reduces, the steadiness and durability degree of single unit system are significantly improved.
Description
Technical field
The invention belongs to water conservancy equipment and water generating field, and in particular to a kind of water generating impeller.
Background technology
Waterpower（Water conservancy）The turbine blade of generating can be divided into two major classes, and a class is lateral（Similar to lateral wind
Motor blade）, a class is turbine type, can be applied to large-scale water-power plant.But with the development of water generating, it is small-sized
Moveable hydroelectric generator it is more and more, if the blade of this kind of generator also use large hydropower station similar blade,
Because its deadweight is smaller, easily by current individual direction impact and rotate when double swerve, so as to cause impeller each
The problem of individual part is produced due to shock, so as to cause the single unit system life-span shorter, maintenance rate is high.
The content of the invention
A kind of water generating impeller of proposition of the present invention.
Realized by following technological means：
A kind of water generating impeller, including impeller axle and impeller blade；
Described impeller axle one end is set and is connected with top bearing, and the other end is connected with end bearing, and same with power transmission shaft in end
Axle is connected.
The impeller blade is multiple, and using whole impeller shaft length as contact site, arc stretches out, and each institute
The width for stating impeller blade is started to step up at the top of impeller axle, extremely most wide with impeller axle end position width.
Reduction of speed plate is inversely provided with inside each impeller blade arc, the reduction of speed plate includes reduction of speed plate root
With reduction of speed wrench portion, the reduction of speed plate root and the impeller blade be affixed, and the reduction of speed plate root width is more than the reduction of speed
Plate head width and the width for being less than fixing position impeller blade, reduction of speed plate root material is high-strength rubber, and reduction of speed wrench portion is
High-strength stainless steel, the reduction of speed plate width is identical in the width of its fixing position with the impeller blade；The reduction of speed plate and institute
The angle for stating impeller blade is δ, and δ angle is chosen for 15 ~ 32 °.
It is provided with each impeller blade sidepiece except dry part, it is described to remove dry part and head except dry part includes root
Portion removes dry part, and the root is arranged on impeller blade close to one end of impeller axle except dry part, is many unidirectional rubber materials
The bar of matter, the head is arranged on the one end of impeller blade away from impeller axle except dry part, is many multidirectional rubber materials
The bar of matter.
Preferably, the impeller blade is 3-8, more preferably 3.
Preferably, the angle except dry part and impeller blade sidepiece is 80 ~ 100 °.
Preferably, the head is two-way setting, the angle of both direction except the bar of the quality of rubber materials of dry part
For 100 ~ 120 °.
Preferably, the head is except 2.5 ~ 3.5 times that the dense degree of dry part is the root noise-reducing components.
Preferably, the position that sets of the reduction of speed plate is to the impeller blade and the distance of impeller axle Fixed Division：It is described
Position to distance=1 of impeller blade top widest part that reduction of speed plate is set：（2~3）.
Preferably, each a diameter of 2 ~ 3mm for removing dry part, length is 8 ~ 10mm.
Preferably, the generally trapezoidal plate construction of reduction of speed plate.
Preferably, the high-strength rubber material is calculated as by quality parts ratio：Natural rubber：50 ~ 58 parts, butyl rubber
Glue：3 ~ 5 parts, epoxy resin：2 ~ 2.5 parts, carbon black：11 ~ 12 parts, plasticizer：2 ~ 3 parts, polyethylene glycol：1 ~ 2 part, calcium sulfate：1~3
Part.
Effect of the invention is that：
1, by impeller blade sidepiece（The especially downward upper lateral part of arc）It is provided with except dry part so that impeller blade exists
Rotation when do not shake substantially so that avoid impeller blade to miscellaneous part produce lateral pressure, cause part too early
The generation of damaged condition.Due to often producing local eddy currents due to the temperature difference in current, so that current flowing is not very steady
It is fixed, it can all produce non-radial power to impeller blade in flow process, and the size and Orientation of this power and unstable,
So as to be easy to that shake is caused to impeller blade, and by being provided with villous rubber strip on the impeller vanes, this is broken up
Plant each to power, it is achieved thereby that the effect of impeller blade stable rotation.
Because the whole plane stress of the impeller blade of rotation is not uniform（End portion width is wide, more walks width toward tip
It is smaller）, therefore by different parts set except dry part different density so that differentiation pressure effect strengthened and
Optimization, is especially being provided with two-way rubber strip so that the effect of differentiation pressure is more strengthened close to end.Closed by choosing
Suitable angle is set so that the effect is optimal.
2, by being provided with the reduction of speed plate inversely set in impeller blade privileged site so that the rotating speed of impeller blade is more
It is stable.Due to current flow velocity not necessarily, when water velocity is excessive when, impeller blade rotates too fast, not only makes
It is unstable into speed, can also be too fast due to rotating speed so that miscellaneous part overheats and causes the lost of life.The reverse drop by setting
Fast plate, and reduction of speed plate different parts material is specifically limited by rationally setting angle, and rationally so that its is existing
Certain elasticity also has certain rigidity, in water flow process, when current enter the region between reduction of speed plate and blade, water
The collision of first and blade is flowed, is then collided again with reduction of speed plate, formation is vortexed, meeting blade again is vortexed when water velocity is excessive
Reverse-impact, so that blade velocity is moderately reduced, and when water velocity is not very big, current can't be obvious
Carry out secondary reverse-impact with blade so that the speed that stabilizer vane is rotated.
3, dry part and reduction of speed plate are removed due to being provided with, therefore by rationally being set to impeller shape so that one
It is 0 to hold width reduction, is then gradually increased, until other end width is maximum.After so setting, it can cause except dry part exists
It is configured on one inclined-plane（And it is the inclined-plane of bending curvature）, so that it removes dry effect（Remove various each to non-master
The water flow dynamic energy of stream）It is more obvious.Set simultaneously reduction of speed plate can also width it is appropriate, but will not have larger difference with length of blade
Not so as to cause larger noncontrolled area.
