Abstract
The utility model discloses an axial flow wind turbine. The axial flow wind turbine comprises a hub and a plurality of blades evenly distributed on the periphery of the hub. A plurality of grooves are formed in the positions, close to the roots of the blades, on the upper end surface of the hub. Reinforcing ribs matched with the grooves in shape are arranged at the front edges of the blades. When axial flow wind turbines are stacked, the grooves correspond to the reinforcing ribs in position. According to the axial flow wind turbine, the grooves are matched with the reinforcing ribs in shape and correspond to the reinforcing ribs in position when axial flow wind turbines are stacked, so that the axial flow wind turbines are easy to position and convenient for a worker to stack.
Description
Technical field
The utility model relates to a kind of axial-flow windwheel.
Background technique
During axial-flow windwheel vanning, a plurality of axial-flow windwheels need to be stacked.Existing axial-flow windwheel, owing to can forming and interfere between wheel hub and blade, cannot be located when stacking, stacking very inconvenient, and the height of heap poststack is higher.Therefore be necessary existing axial-flow windwheel to improve.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of location, stacking convenience, stacks as high is low, vanning amount is large axial-flow windwheel of being easy to.
In order to solve the problems of the technologies described above, technological scheme provided by the utility model is: a kind of axial-flow windwheel, comprises wheel hub, and be evenly distributed on a plurality of blades in wheel hub periphery; The upper-end surface of described wheel hub is provided with a plurality of grooves near blade root place; Described blade inlet edge place is provided with the stiffening rib that the shape with groove matches; When described axial-flow windwheel is stacking, groove is corresponding with the position of stiffening rib.
Groove on the blade root place end face of described wheel hub is arc, and the two ends of groove are provided with fillet; The cross section camber of the stiffening rib of described blade inlet edge.
The outside of described wheel hub is provided with diagonal bar near blade root place and strengthens structure; When described axial-flow windwheel is stacking, the upper-end surface of an axial-flow windwheel and the laminating of the lower end surface of another axial-flow windwheel; Ju Li≤4/5 of superstructure is strengthened to the distance/lower end surface of upper-end surface in described 1/2≤lower end surface to diagonal bar.
Adopted after technique scheme, the utlity model has following beneficial effect: the shape of (1) groove of the present utility model and stiffening rib has matched, and when stacking, position is corresponding, be easy to location, facilitated workman stacking.
(2) groove of the present utility model and stiffening rib are arc, and stacking time location is more prone to.
(3) outside of wheel hub of the present utility model is provided with diagonal bar reinforcement structure near blade root place, and the height of wheel hub is reduced; When stacking, the upper-end surface of an axial-flow windwheel and the laminating of the lower end surface of another axial-flow windwheel, reduced stacks as high, promoted vanning amount.
