Abstract
The utility model discloses a vertical-axis impeller pitch varying device comprising an impeller rotating shaft, blade supports, blades, a blade pitch variation pusher and a tail wing. The blade supports rotate around the impeller rotating shaft. The blades are fixed to the ends of the blade supports. The blade pitch variation pusher and the tail wing are arranged at the top of the impeller rotating shaft. The blade pitch variation pusher is connected with the impeller rotating shaft through a bearing and is movably connected with the blades through variable pitch links. An intersection of the outline of the blade pitch variation pusher and a spanwise line of the tail wing and another intersection of the outline of the blade pitch variation pusher and a spanwise reverse extension line of the tail ring are equally away from a center of the impeller rotating shaft. Under the action of wind force, the tail wing drives the blades to deflect through the blade pitch variation pusher and the variable pitch links, and acting capability of a maximum acting area is given to full play; meanwhile, acting capability of a minimum acting area is substantially improved, and the effect is improved significantly.
Description
Technical field
The utility model relate to a kind of can be for the vane change device of for example wind energy conversion system or energy by ocean current power generating equipment.
Background technique
The problem that existing feather lifting upright shaft impeller exists is: originally exert oneself local because the pneumatic angle of attack is larger preferably, in feather process, continue to increase, easily there is stall phenomenon and do not reach the object of feather, because feather is less in the weak part feather of exerting oneself, do not reach to improve yet and exert oneself compared with the power efficiency of weak part blade simultaneously.
Therefore, the performance of existing upright shaft wind motor impeller is not good, needs to redesign.
Model utility content
Model utility object: provide a kind of vertical shaft impeller to become oar device, to address the above problem.
Technological scheme: a kind of vertical shaft impeller becomes oar device, comprises impeller shaft, the blade rack rotating around impeller shaft, and the blade that is fixed on blade rack end, is arranged on vane propeller-changing pusher and the empennage at impeller shaft top; Vane propeller-changing pusher connects with impeller shaft by bearing, and is actively coupled by becoming oar connecting rod and blade; Described empennage is fixedly connected with becoming oar pusher, the outer contour of described change oar pusher and empennage exhibition to, empennage open up to two intersection points of reverse elongation line apart from the distance of spindle central, equate.
Described change oar pusher outer contour is into being heart.Described blade and blade rack are by sharf chain connection; Described change oar connecting rod is divided into the two-part that are actively coupled, and a part is hinged with blade; Another part and blade rack are collinear fixes and produces by Returnning spring the reposition force stretching to the impeller shaft heart.
Beneficial effect: under the effect of wind-force, empennage, by vane propeller-changing pusher, change oar connecting rod drive blade deflection, is given full play to the acting ability in maximum acting region, makes minimum acting ability of doing work region obtain the improvement of essence simultaneously, effect improved obvious.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Wherein, 1, blade; 2, become oar pusher; 3, impeller shaft; 7, blade rack, 8, Returnning spring; 9, become oar connecting rod; 10, steamboat; 11, empennage.
Embodiment
As shown in Figure 1, vertical shaft impeller of the present utility model becomes oar device and comprises impeller shaft 3, the blade rack rotating around impeller shaft 3, and the blade 1 that is fixed on blade rack end, is arranged on vane propeller-changing pusher 2 and the empennage 11 at impeller shaft 3 tops; Vane propeller-changing pusher connects with impeller shaft by bearing, and is actively coupled with blade 1 by becoming oar connecting rod 4; Empennage is fixedly connected with becoming oar pusher, the outer contour that becomes oar pusher and empennage exhibition to, empennage open up to two intersection points of reverse elongation line apart from the distance at rotating shaft 3 centers, equate.Become oar pusher outer contour into being heart.Blade and blade rack are by sharf chain connection; Become oar connecting rod and be divided into the two-part that are actively coupled, a part is hinged with blade; Another part and blade rack 7 are collinear to be fixed and passes through the reposition force that Returnning spring 8 generations stretch to the impeller shaft heart, and the change oar connecting rod of this part is contacted at and become oar pusher by steamboat 10.
Under the drag effect of wind, empennage 11 is all the time in downwind position, and empennage is opened up to consistent with wind direction all the time, and empennage drives variable pitch driver 2, change oar connecting rod to push away, make blade when 0 ° of azimythal angle and 180 ° of azimythal angles, not become oar, when 90 ° and 270 °, become vane angle maximum.And Returnning spring promote to become the power of oar pusher to axis, the steamboat 10 that makes to become oar connecting rod one end is close to all the time the surface of variable pitch driver 4 and is moved.
Blade of the present utility model can all have the higher pneumatic angle of attack at one week any one azimythal angle of rotation, higher raising the effect of whole aeroperformance of lifting upright shaft impeller.The novel feather vertical shaft impeller unit of this impeller is also applicable in low-head hydraulic generating and marine tidal-current energy water turbine.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple equivalents to the technical solution of the utility model, these equivalents all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
