Abstract

The invention discloses a movable-wing type windmill, which is a device for generating electricity with wind power and hydraulic power. The device is formed by connecting a plurality of frames (2) to a mandrel (1) in a surrounding way, wherein the frames are provided with small doors (3) forming movable wings; small door shafts (4) are longitudinally arranged on the upper and lower edges of the frames (2); and the width (5) of the small door is greater than a distance (6) between every two small door shafts (4). When the device is windward, the small doors are closed when the movable wings are in downwind areas, and are opened when the movable wings are in upwind areas, and door surfaces are parallel to wind current. Therefore, the device has the characteristics of high working force and low recoil. Due to the structure where the planes of the movable wings are parallel to the mandrel and rotate around the mandrel, the device has no requirement on the direction of the wind current.

Description

Movable-wing type windmill

[technical field]

The present invention relates to a kind of wind-force, waterpower acting, device of generating of utilizing.

[background technique]

So far, the device of wind-power electricity generation is still " spiral windmill " in the world.This windmill efficient is low, and recoil is big, could turn round over against distinguished and admirable again.At its shortcoming, done tall and big support to it, add wind plant, but powerless to its low this shortcoming of power.

[summary of the invention]

The objective of the invention is to provide a kind of " movable-wing type windmill " device, the high recoil of its power is little, and its running is to the no requirement (NR) that flows to of wind, water.

The object of the present invention is achieved like this: this device be by several framework solderless wrapped connections on an axle, this axle is perpendicular to horizontal line, the angle between framework equates, constitutes a few fan wickets of the wing of living, it vertically is connected in the last bottom of framework; Also can laterally be connected on the around side, just a kind of weak effect in back.The wide distance of being a bit larger tham between the door-hinge of wicket can only can not be crossed framework in one side of framework opening and closing when making the wicket facing the wind.Wicket can be placed on the front or the back side of framework, the identical switched in opposite of principle.During " movable-wing type windmill " facing the wind, the wing of living whenever circles and half cycle is all arranged with the wind, and half cycle against the wind.Wicket front wind-engaging when with the wind changeing, wind pushes away wicket and closes; Wicket back side wind-engaging when changeing against the wind, wind pushes away wicket and opens, wicket and distinguished and admirable keeping parallelism.The little shop front was kept out the wind when the wing of living changeed with the wind, the power that is produced is made as F, wicket axle bumper wind when changeing against the wind, the power that is produced is made as (f), the cross-section area of little door-hinge is very little, be again cylindrical body, so, | f | very little, | f | with | F | ratio can be little to some thousandths of, if one one " movable-wing type windmill " is to be made of 4 wings alive, as calculated: its sine and mean value be 0.9, thus: the efficient height of " movable-wing type windmill ", the recoil of movable-wing type windmill windmill be 2 (f)+the suffered wind-force of framework, because of framework also is a cylindrical body, the resistance that is produced is also as | f | and little, this recoil is the 1-2% of F at most." movable-wing type windmill " is the structure in wing plane parallel alive axle center, makes its running to wind-force requirement be arranged, to the wind direction no requirement (NR).

Compare with " spiral shell slurry formula windmill " with " movable-wing type windmill ", establish that the slurry of " spiral windmill " is long to be R, then its running track is a spheroid, and with the space of this spheroid running track as " movable-wing type windmill ", then the area of the every wing alive is 1/2 π R ², " movable-wing type windmill " suffered wind-force is F (wing of living)=1/2 π R ^{2f (wind-force) 0.9}(4 wing sines alive and mean value), the suffered wind-force of propeller windmill is F (propeller)=π R ^{2f (wind-force)}Sinacosa has done preferably in practicality to the strength of doing power, various resistance, recoil, propeller of " propeller windmill " etc., the area of getting propeller usually only reaches 1/4 π R ^{2f (wind-force)}Sin32 ° .cos32 °, calculate: F (wing of living): F (spiral shell practicality)=4: 1, (spiral shell recoil) calculates if the recoil of propeller windmill is F: F (spiral shell recoil): (spiral shell practicality)=62%, comparative result is known: the efficient of " movable-wing type windmill " is bigger 3 times than the efficient of " propeller windmill ", " propeller windmill " recoil is 62% with the ratio of doing power, and this ratio of " movable-wing type windmill " is 1-2%.The structure that makes " movable-wing type windmill " is support greatly not; Device must not facing the wind.Construction not hard to imagine " movable-wing type windmill " is easily simple.Cheap, can obtain high-power again.

[description of drawings]

Fig. 1 proposes " movable-wing type windmill " device sectional drawing according to the present invention.

[embodiment]

This device comprises 1 axle center 1, the framework 2 of several solderless wrapped connections on axle sleeve 11, and angle equates between the framework.Axle center 1 vertical water horizontal line, a few fan wickets 3 of the formation wing alive are vertically installed in door-hinge 4 in the last bottom of framework 2, or are horizontally installed in the around side of framework 2.A kind of weak effect in back.Press Fig. 1 axle center 1 on a left side, framework 2 is on the right side.Wicket 3 is placed on the here positive of framework 2, and this just constitutes the example of the wing alive that changes counterclockwise; If wicket 3 is placed on the back side (not drawing among the figure) of framework 2, just constitute the example of the wing alive that changes clockwise.

It shown in Fig. 1 arrow 7 flow direction of wind, the wing of living rotates along the counter clockwise direction shown in the arrow 10 under distinguished and admirable 7 promotion, when the wing forwards distinguished and admirable 7 point 8 to if a slice is lived, framework 2 and wicket 3 are all with distinguished and admirable parallel, therefore, wicket 3 is fitted on the framework 2 in turn, after the wing of living leaves a little 8, distinguished and admirable 7 blow in the front of wicket 3, because of wicket 3 wide 5 greater than the distance between the door-hinge 46, so, wicket 3 can not forward the back side of framework 2 to, still fit on framework 2, this sheet is lived wing when rotate half cycle, just in time be in distinguished and admirable 7 another put on 9.After the wing of living leaves a little 9, the distinguished and admirable back side that just blows to wicket 3, wicket 3 is opened because of the back side is subjected to the promotion of wind-force, 180 ° of wicket 3 counterclockwise rotations are to reach parallel with distinguished and admirable 7, and keep this parallel half cycle of covering, return initial point 8, the power that the wing facing the wind of living produces has been finished wind-power electricity generation by axle sleeve 11 by transmission, speed change gear 12 motor 13 that linked.When power was excessive, iron ball 14 can obtain enough big centrifugal force, made clutch 16 coupling axle sleeves 11 realize the automatic control generating by transmission device 12 motor 13 that linked by connecting rod 15.

Claims

1. a movable-wing type windmill is characterized in that by axle center (1), around the axle center (1) and framework (2) that changes and the wicket (3) that is contained on the framework (2) constitute.
