Abstract
The utility model relates to a windmill with backward oblique oar blades, which belongs to the improvement of a windmill structure. The utility model provides a windmill with backward oblique oar blades, which has small volume of an upright post and thinness of root parts of oar blades. The utility model comprises an upright post provided with a generator. The utility model has the essential structure that the top end of the upright post is provided with pull wires connected with the ground; oar blades are arranged on a shaft of a supporting plate at the end of a generator shaft, and the root parts of the oar blades are in contact with a sliding plate at one side of a spring of the generator shaft; bevel gears on the upright post are engaged with bevel gears on a shell body of the generator, and the side parts of gears which are coaxial with the bevel gears are provided with springs, and are engaged with gears on the generator shaft; one end of a wind blocking plate is fixed to the shell body of the generator through a pin shaft, and the wind blocking plate is in contact with the gears.
Description
Technical field:
The utility model is the improvement that belongs to windmill structure.
Background technique:
The column volume of present windmill is bigger, and the root of blade is thicker, gives to install and use and brings a little inconvenience.
The model utility content:
The utility model is exactly at the problems referred to above, provides a kind of column volume little, but the windmill of the thin rear-inclined blade of propeller shank.
The utility model adopts following technological scheme: the utility model comprises the column with generator, and its structure outline is that the column top is provided with the backguy that connects with ground; Have blade on the axle of the dunnage of generator axle head, the root of blade contacts with the slide plate of spring one side of generator shaft; Umbrella gear on the column is meshed with umbrella gear on the housing of generator, side with the coaxial gear of umbrella gear has spring, also can be meshed with the gear on the generator shaft, one end of barge board is fixed on the generator housing by bearing pin, and can contact with gear.
The beneficial effects of the utility model:
Because backguy is adopted on the column top, the root of blade is provided with adjusting device, and the root of column, blade is attenuated, and provides convenience for installing and using;
In addition, the utility model is provided with barge board, can adjust the operation with the wind all the time of the utility model blade, has guaranteed that backguy plays effect should be arranged.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment:
The utility model comprises the column 1 with generator 8, and column 1 top is provided with the backguy 2 that connects with ground; Have blade 3 on the axle 6 of the dunnage 5 of generator shaft 15 ends, the root of blade 3 contacts with the slide plate 7 of spring 17 1 sides of generator shaft 15; Umbrella gear 4 on the column 1 is meshed with umbrella gear 9 on the housing of generator 8, have spring 14, and can be meshed with the side of the gear 12 of umbrella gear 9 coaxial 16 with the gear on the generator shaft 15 13, one end of barge board 10 is fixed on generator 8 housings by bearing pin 11, and can contact with gear 12.
The surface of blade 3 is provided with the corner angle 18 of projection, can increase the resistance of wind, improves using effect of the present utility model.
Descend and an accompanying drawings course of action of the present utility model:
During use, at first fixture is gone up in the backguy 2 on column 1 top with ground and linked to each other, blade 3 (promptly flowing to the wind of blade 3) normal operation under situation with the wind by generator 8.When wind-force bigger, but the root push skateboard 7 of blade 3 move, then blade 3 hypsokinesis can reduce the resistance of wind.When with the wind direction (promptly being flowed to the wind of blade 3 by generator 8) changes, the bearing pin 11 of barge board 10 on generator 8 housings moves, promotion gear 12 moves (pressure spring 14 simultaneously) and is meshed with the gear on the generator shaft 15 13, just umbrella gear 4 rotations on column 1 of generator shaft 15, promptly entire blade 3 is just rotated towards downwind.
Claims (2)
