Definitions
- the present invention relates to a sail wing type windmill and operation method of same, and more particularly, a sail wing type windmill to convert the wind power into the mechanical power, and its operation method.
- a horizontal shaft windmill composed of three or four vaned wing with fly wheels is coupled to the generator shaft to drive the generator with the windmill.
- the rotating power of the windmill comes from upwards and downwards wind flow attacking the wing blades of the windmill, whereas the flywheel is for storing the kinetic energy ' and governing the rotational speed of the windmill.
- the conventional technique used to convert the wind power (mechanical power) into the electric power described above has several shortcomings, namely:
- Another obj ect of the present invention is to provide a sail wing type windmill which can work in all direction without the need of tracing the wind direction from time to time, and the windmill can be fabricated and assembled with reduced cost while it can be operated securely.
- Another obj ect of the present invention is to provide the method of the operation of this sail wing type wind mill.
- a vertical shaft is provided for the windmill instead of the conventional horizontal shaft so as to reduce the engineering cost.
- a sail type wing blade is adopted to replace the propeller type wing blade thereby eliminating the windage loss arising from cutting the wirid strata to improve energy conversion efficiency as high as possible.
- a rudder is designed to turn freely about the windmill shaft by a turn table which has a twin vaned tail wing at its rear end which can automatically turn the rudder to face against the wind direction by the turn table with a concave upwardly curved lead rail.
- the wing blade and the lead rail is connected with a connecting ; rod which is movable on the lead rail with an end roller and j ointed with the wing blade at its front portion.
- fly wheels are provided radially extended from a fly wheel hub.
- Each fly wheel is configurated into a stream saucer (or spherical) form so as to reduce the wind resistance.
- Each fly wheel is filled with a weighty substance to improve its fly wheel effect.
- Fig. 1 is a perspective view of the present invention
- Fig. 2 is a schematic view showing the connection of the wing blade and the fly wheel according to the present invention
- Fig. 3 is a schematic view illustrating how the lead rail of the wing blades is operated according to the present invention
- Fig. 4 is a schematic view of the rotating wing blades looked downwards.
- a shaft 5 of the windmill is vertically erected to be conj oined with the rotating shaft of a generator.
- a fly wheel hub 1 is coupled to the shaft 1 and several centrifugal fly wheels 1 1 are radially extended from the hub 1 each with a supporting brace so that the fly wheels 1 1 are disposed circularly.
- Each fly wheel 1 1 is configurated into a stream saucer ( or spherical) form so as to reduce the windage resistance.
- Each fly wheel 1 1 is filled with a weighty substance to improve its fly wheel effect.
- each supporting brace of the fly wheel 1 1 is provided with a jaw 12 proximate to the hub 1 to hook each of fan blades 21 , 22, 23 , 24 onto a recess hole formed onto the brace so that the fan blades 21 , 22, 23 , 24 are rotatable along with the fly wheels 1 1.
- a rudder 4 is designed to turn freely about the shaft 5 by a turn table 42 which has a twin vaned tail wing 41 at its rear end to divide the window stream flowing in the two directions along each of the two symmetrically arranged vanes with respect to the rudder lever.
- the rudder 4 can be constantly turned to face against the wind direction by the turn table 42 so as to trace the wind direction automatically.
- the turn table 42 is provided with a concave upwardly curved lead rail 43 offset of the wind direction.
- Each of the wing blades 21 , 22, 23 , 24 is connected to the lead rail 43 with a connecting rod 31 which is movable on the lead rail 43 with an end roller, while its front portion is jointed to the wing blade 21.
- a connecting rod 31 which is movable on the lead rail 43 with an end roller, while its front portion is jointed to the wing blade 21.
- the wing blade 21 develops its blade surface to accept the wind flow.
- the wind pressure is exerted normal to its blade surface such that the windmill is ready to work with maximum efficiency.
- the velocity of the air molecules flowing along the surface of the wing blade 21 is approximately equal to the wind velocity.
- the velocity of the air molecules gradually slows down as the air molecules approaches the rear surface of the wing blade 21 so that there appears a wind pressure difference between the two surfaces of the wing blade 21 , and this difference is further enlarged by the air viscosity to the rear surface of the wing blade 21 arising from the random air current passing therealong.
- a clockwise rotating torque see Fig.
- the centrifugal fly wheel 1 1 filled with a weighty, substance contributes to serving the fly wheel effect wit L h its improved rotational inertia by adjusting the non-uniform rotating torque of the windmill arising from the unstably varying wind pressure and governing the windmill to operate under constant rotational speed as well,
