Description
Affiliated technical field
The utility model relates to a kind of wind energy impeller, is mainly used in wind-power electricity generation or machine power is provided.
Background technique
At present, the device that extensively utilizes wind energy is that propeller-type wind energy impeller (for ease of difference, is called for short paddle wheel, as follows), its spin axis is parallel with wind direction, and several blades that utilize wind-force to promote on the paddle wheel make the paddle wheel rotation, pass through the external output torque of running shaft of paddle wheel then.Because the surface of revolution of paddle wheel must could obtain more wind energy over against wind direction, so need be installed in paddle wheel on the support greater than the paddle wheel radius, could normally rotate, but this bring many inconvenience must for direct transmission kinetic energy (not by the electric energy conversion process) and daily maintenance and repair.In addition, paddle need be used the method for adjustment " pitch ", reach under the situation of different wind speed can both the high efficiency running purpose; Paddle wheel also needs to increase a cover wind direction induction and a servo-system again, so that, allow the surface of revolution of paddle wheel align wind direction all the time according to the variation of wind direction, otherwise, when wind direction has greatly changed, stop operating to such an extent as to promptly cause the efficient of paddle wheel to descend significantly; Paddle wheel not only needs to increase above-mentioned two cover regulating devices, but also will provide certain energy for this two covers regulating device, and not only its construction and standing charges are high, and can only turn round in the environment of 2 dimension wind directions.
Summary of the invention
Can not in the environment of 3 dimension wind directions, work in order to overcome paddle wheel, and need be for adapting to the deficiency that wind direction and change of wind velocity are provided with two cover regulating devices, the purpose of this utility model provides a kind of wind energy impeller, handle the mode of blade rotation works with the wind-force rudder, it not only can rotate in the environment of 3 dimension wind directions, nor two above-mentioned cover regulating devices need be set.
The technological scheme that the utility model technical solution problem is taked is:
The running shaft of impeller is installed between two bearings, these two bearings are separately fixed on support or the base, in the axostylus axostyle stage casing of running shaft along circumference 4 spiral arms that evenly distribute, the inner segment of every spiral arm is installed a wind-force rudder by axle sleeve, then by another axle sleeve a blade is installed for outer section of spiral arm, by the speed change gear engagement, the velocity ratio of speed change gear is 2: 1 between two axle sleeves, if be wind-force rudderpost cover Rotate 180 degree, then the blade axle sleeve only revolves and turn 90 degrees.Therefore, not only wind-force rudder on every spiral arm and blade can rotate around this spiral arm respectively by axle sleeve separately, and whole 4 wind-force rudders and 4 blades of this wind energy impeller also rotate in the space that support comprises around running shaft together simultaneously.
The blade axle sleeve is divided into two-part that area equates, shape is identical with blade, and therefore, for the blade axle sleeve, no matter wind blows blade from which direction, and blade can not produce significantly, center on the moment that the outer section of spiral arm is rotated.The wind-force rudder then all is in a side of its axle sleeve, its area is 1/2 of a blade area, so, as long as angle of axial existence of wind direction and spiral arm (wind direction and spiral arm axially not parallel), the wind-force rudder promptly can be under aerodynamic effect, rotate around the spiral arm inner segment by wind-force rudderpost cover, the air pressure difference until wind-force rudder two sides is zero; In sum, under the effect of wind-force, the wind-force rudder only can occur and drive blade rotation by speed change gear and blade pass can not occur and cross speed change gear and drive the phenomenon that the wind-force rudder rotates conversely.
For this wind energy impeller (hereinafter to be referred as steering wheel) is rotated under the effect of wind-force continuously reposefully, a rudder point winglet is installed respectively on the top of every wind-force rudder, the area of this winglet is 1/10 of the wind-force area of rudder.Differ the established angle of 20 degree between the plane of winglet plane and corresponding wind-force rudder; Be installed in the adverse effect of a side of its axle sleeve in order to eliminate the wind-force rudder, put a side relative at each wind-force rudderpost a counterweight is installed, make the gravitational moment of wind-force rudderpost cover both sides reach balance with the wind-force rudder to the rotation generation.In addition, 4 blades are installed in the following order: when counterweights parallel with the horizon when the surface of revolution of steering wheel, 4 wind-force rudders were all pointed to counterclockwise direction (overlooking, i.e. the steering wheel sense of rotation that will have), the plane of 4 blades was parallel with the wind-force rudder plane.
Because steering wheel can be worked in the environment of any wind direction (principle aftermentioned), so the installation direction of its running shaft without limits, in other words, between the height of the radius of steering wheel and its support, there is not inevitable corresponding relation, no matter the steering wheel of much diameters can be placed in overhead less than just running well on 1 meter the height; In addition, steering wheel has automatic adaptive capacity to different wind speed and directions, does not have adjustment " pitch " or aligns the problem of wind direction, so long as in common wind speed range, no matter be wind, can promote steering wheel and enter normal rotation status automatically from that direction.
The beneficial effects of the utility model are, can in the environment of 3 dimension wind directions, run well, it is very low that its support height can be built, not only shortened the transmitting range of kinetic energy output, and convenient daily maintenance and repair, also saved fully to adapting to the two cover regulating devices that wind direction and change of wind velocity are provided with, reduced the expense of building and keeping on the go; It can also be applied on the kickboard of sea, on the ship, among the particular surroundings greater than 2 dimension wind directions such as ridge, mansion top except can working in the environment of general 2 dimension wind directions.

Specific implementation method
In Fig. 1, the two ends of steering wheel running shaft (3) are installed on support (1) and the base (8) by bearing (2) respectively, support is that the steel pipes of 120 degree are formed by 3 mutual angles, and in order to the bearing on the fixing running shaft, the lower end of 3 steel pipes fixes on the ground.Base is used for fixing the bottom end bearing of running shaft, and bears the gravity of steering wheel.4 cover spiral arm combinations (4) are evenly distributed on the stage casing of running shaft, 4 blades (5) the then axle sleeve (13) by separately are installed in respectively on outer section of 4 spiral arms, and 4 wind-force rudders (7) the then axle sleeve (12) by separately are installed in respectively on the inner segment of 4 spiral arms.So 4 wind-force rudders and blade not only can rotate in the space that support comprises around the steering wheel running shaft together, simultaneously also can be respectively axle sleeve by separately rotate around corresponding spiral arm.If this steering wheel is used for generating, then the running shaft of steering wheel drives generator (9) rotation by accelerating gear.
In Fig. 2, the situation that wind-force rudder and blade are rotated a circle when being in diverse location is respectively described below:
＜1〉in the spiral arm combination of A point direction (steering wheel corner 0 degree): when steering wheel is static when not changeing, which kind of angle blade (5) and wind-force rudder (7) that no matter this spiral arm makes up on (4) are in, as long as wind-force is enough big, the wind comes from and to blow the wind-force rudder and make its counterweight (10) align the direction of the wind comes from, driving the blade rotation simultaneously makes its blade face parallel with wind direction, at this moment the blade on this spiral arm makes up, wind-force rudder and rudder point winglet (6) is totally 3 blade faces all parallel with wind direction (promptly the elevation angle to wind direction is zero), so resistance of air minimum, at this moment can be considered the zero point that steering wheel begins to rotate, the starting point (zero point) of also rotating around spiral arm as wind-force rudder and blade simultaneously is with convenient statement hereinafter.
＜2〉spiral arm in orientation, A-B district (steering wheel corner 0-90 degree) makes up: under the moment of rotation that other blade produces promotes, steering wheel begins counterclockwise direction and rotates, the rudder point winglet outer side surface in this orientation begins to meet to the wind comes from, the elevation angle of the side of facining the wind is for just, generation makes the clockwise moment of [for spiral arm, from A-B district to running shaft (3) direction] rotation of wind-force rudder, along with the increase of rotation angle, the elevation angle of the side of facining the wind of rudder point winglet also increases, so this moment increases synchronously; But, in a single day the wind-force rudder clockwise rotates, its windward side promptly produces under the effect of wind-force and stops the counter-clockwise moment (because of the elevation angle is negative) that self is rotated further, because its wind-exposuring area is far longer than the outside wind-exposuring area of rudder point winglet, so the counter-clockwise moment that it produces plays the effect that limits the speed that self clockwise rotates, the rotation angle of self is only increased with extremely slow speed, therefore, blade clockwise rotates around spiral arm with slower speed (2: 1) thereupon, makes up near the B district until this spiral arm.
At spiral arm during near B district (steering wheel corner about 75 degree), though the wind-exposuring area of wind-force rudder does not change, but since the effect that its relies on wind-force to produce counterclockwise direction moment progressively lose (because of the spiral arm center line progressively parallel with wind direction, promptly progressively lose its wind direction rudder face effect), thereby the counterclockwise direction moment that produces obviously reduces, the wind-force rudder that makes that produces at rudder point winglet clockwise rotates under the promotion of moment, and the wind-force rudder drives blade to begin to quicken to clockwise rotate.
In this orientation, the blade on this spiral arm does not produce and promotes the moment that the steering wheel inhour is rotated.
＜3〉spiral arm of (the about 90-95 degree of steering wheel corner) direction combination in the B district: (the wind-force rudder is pairing air-flow when rotating for the center line of spiral arm and relative wind, the direction of this air-flow be wind direction and the rotation the rightabout direction of closing) direction parallel, blade and wind-force rudder all are zero degree to the elevation angle of relative wind, the wind-force rudder has lost the wind direction effect fully, promptly can not produce the moment of rotation of any direction because of relative wind, the wind-force rudder is under the promotion of rudder point winglet, only need overcome air to the resistance that wind-force rudder and blade are produced when rotating, drive blade and continue to quicken to clockwise rotate.
＜4〉spiral arm in B-C (steering wheel corner 90-180 degree) orientation makes up: the spiral arm combination is in case crosses B district (the about 90-95 degree of steering wheel corner) direction, the wind-force rudder has promptly recovered the wind direction effect of rudder face, but the wind-force rudder changed over the another side and met to the wind comes from this moment, thereby the moment of rotation that produces also becomes clockwise (for spiral arm, from the B-C district to the running shaft direction) direction, the wind-force rudder is under the effect of this moment, beginning to promote self jointly with rudder point winglet clockwise rotates at faster speed, until the rudder face of wind-force rudder with (this moment, the wind-force rudder rotated 180 degree till wind direction is parallel, blade rotation 90 the degree, the steering wheel corner be about 105 the degree); If continue to clockwise rotate under the promotion of wind-force rudder after this because of rotator inertia and rudder point winglet, then the windward side because of the wind-force rudder also will change thereupon, the moment of rotation that produces will become counterclockwise direction, and the wind-force rudder can be got back to the position substantially parallel with wind direction rapidly under the effect of this counterclockwise direction moment.
Since blade rotation 90 the degree, the plane of blade begins to meet to the wind comes from, and blade outer rim (23) elevation angle is just (for wind direction), so raise in the windward side of this blade one side air pressure, this blade is begun to produce the active force of counterclockwise direction (to the running shaft of steering wheel), this active force is vertical with spiral arm all the time, forms to promote the moment that the steering wheel inhour is rotated.Along with the rotation of steering wheel, the outer rim elevation angle of blade progressively increases, so the moment that the promotion steering wheel of this blade generation rotates also increases thereupon.
＜5〉spiral arm in C point (steering wheel corner 180 degree) direction makes up: the outer rim elevation angle of blade is that 90 degree are [for wind direction, the elevation angle of blade inner edge (24) also is 90 degree], this moment, the wind-force rudder was all parallel with wind direction with the blade face of rudder point winglet, and blade plane is vertical with the direction of the wind comes from, the wind-exposuring area of blade reaches maximum value, blade facing the wind the pressure of a side rise to the highest, so the moment of the promotion steering wheel counterclockwise rotation that this blade produces also reaches maximum value.
＜6〉spiral arm in (steering wheel corner 180-270 degree) orientation combination in the C-D district: along with the rotation of steering wheel, the blade outer rim begins the subtend opposite direction of the wind comes from, the blade inner edge then begins the direction that subtend be the wind comes from, the counterclockwise direction moment that the promotion steering wheel that produces on the blade rotates also reduces gradually along with reducing of the blade inner edge elevation angle.
Meanwhile, the inner side surface of this orientation rudder point winglet begins to meet to the wind comes from, the elevation angle of the side of facining the wind is for just, generation makes wind-force rudder inhour (for spiral arm, from the C-D district to the running shaft direction) moment of rotating, along with the increase of rotation angle, rudder point winglet also increases at the elevation angle of a side down with the wind, so this moment increases synchronously; But, the wind-force rudder is in case the inhour rotation, its windward side promptly produces under the effect of wind-force and stops the clockwise moment that self is rotated further, because its wind-exposuring area is far longer than the inboard wind-exposuring area of rudder point winglet, so the clockwise moment that its produces plays the effect that limits self counter-clockwise rotation speed, the rotation angle of self is only increased, therefore with extremely slow speed, blade rotates with slower speed (2: 1) inhour thereupon, makes up near the D district until this spiral arm.
When spiral arm makes up near D district (about 255 degree of steering wheel corner), though the wind-exposuring area of wind-force rudder does not change, but since the effect that its relies on wind-force to produce clockwise moment progressively lose (because of the spiral arm center line progressively parallel with wind direction, promptly progressively lose its wind direction rudder face effect), thereby the clockwise moment that produces obviously reduces, under the promotion that makes wind-force rudder counterclockwise rotation braking torque that rudder point winglet produces, the wind-force rudder drives blade and begins to quicken the inhour rotation.
＜7〉spiral arm of (the about 265-270 degree of steering wheel corner) direction combination in the D district: (the wind-force rudder is pairing air-flow when rotating for spiral arm center line and relative wind, the direction of this air-flow be wind direction and the rotation the rightabout direction of closing) direction parallel, the blade face of blade and wind-force rudder is all parallel with the direction of relative wind, the wind-force rudder has lost the wind direction effect fully, promptly can not produce the moment of rotation of any direction because of relative wind, this moment, the wind-force rudder was under the promotion of rudder point winglet, the resistance that produces in the time of only need overcoming air to wind-force rudder and blade rotation drives blade and continues to quicken counter-clockwise the rotation.
＜8〉spiral arm in (steering wheel corner 270-360 degree) orientation combination in the D-A district: the spiral arm combination is in case cross D district (the about 265-270 degree of steering wheel corner) direction, the wind-force rudder has promptly recovered the wind direction effect of rudder face, but the wind-force rudder changed over the another side and met to the wind comes from this moment, thereby the moment of rotation that produces also becomes inhour (for spiral arm, from the D-A district to the running shaft direction) direction, the wind-force rudder is under the effect of this moment, begin to promote jointly self inhour rotation at faster speed with rudder point winglet, until the rudder face of wind-force rudder with (the wind-force rudder rotated 180 degree and got back to zero degree this moment till wind direction is parallel, blade rotation 90 the degree, the blade face of blade returns to parallel with wind direction again, and the steering wheel corner is about 285 degree); If after this wind-force rudder continues the inhour rotation down because of the promotion of rotator inertia and rudder point winglet, then the windward side because of the wind-force rudder also will change thereupon, the moment of rotation that produces will become clockwise direction, and the wind-force rudder can be got back to the position substantially parallel with wind direction rapidly under the effect of this clockwise moment.
Since blade rotation 90 degree, the plane of blade is substantially parallel with wind direction, resistance of air is very little, blade does not produce the moment that promotes the counter-clockwise rotation of steering wheel in orientation, D-A district.And along with the rotation of steering wheel, the wind-exposuring area of rudder point winglet also progressively reduces, and the moment that the promotion wind-force rudder counterclockwise direction that it produced is rotated reduces thereupon, is reduced to zero until in A point direction the time.
＜9〉spiral arm of getting back to A point (steering wheel corner 360 degree) direction makes up: totally 3 blade faces are all parallel with wind direction for the blade in this spiral arm combination, wind-force rudder and rudder point winglet, so the resistance of air minimum; After A point direction is crossed in the combination of this spiral arm, promptly begin to repeat above-mentioned＜2 〉-＜9 movement process.
In Fig. 3,4 spiral arms (11) are evenly distributed on the stage casing of running shaft (3), and the center line of each spiral arm is vertical with the rotating shaft center line.On the inner segment of spiral arm, wind-force rudderpost cover (12) is installed by one group of tappered roller bearing (seeing E and F district), one side of this axle sleeve is fixed a wind-force rudder (7), a slice rudder point winglet (6) is installed on the top of wind-force rudder, its area is 1/10 of a wind-force rudder, and becomes 20 degree angles with the wind-force rudder plane (has lifted up outside the page on the long limit of outer rim that is winglet on this figure); Opposite side at wind-force rudderpost cover is fixed a counterweight (10).Blade axle sleeve (13) is installed in by one group of cone and cup bearing (seeing F and G district) on outer section of spiral arm, and this axle sleeve is divided into two-part that area equates, shape is identical with blade (5), and the area of wind-force rudder is 1/2 of a whole blade area.
In Fig. 4, whole running shaft (3) is divided into 3 sections, connects into an integral body with bolt, and 4 fitting seats that are used for fixing spiral arm (11) are arranged on its stage casing.
In Fig. 5, spiral arm (11) is fixed on the fitting seat of running shaft (3), and left side one end of wind-force rudderpost cover (12) is installed on the spiral arm by tappered roller bearing (19).
In Fig. 6, right side one end of wind-force rudderpost cover (12) is installed on the spiral arm (11) by another tappered roller bearing (20).Left side one end of blade axle sleeve (13) is installed on the spiral arm by cone and cup bearing (21).Speed change gear mounting disc (18) is fixed on the spiral arm, the internal gear (14) of wind-force rudderpost cover right-hand member and speed changer gearwheel (15) engagement, the internal gear (17) of blade axle sleeve left end and speed changer small gear (16) engagement.
In Fig. 7, right side one end of blade axle sleeve (13) is installed on the spiral arm (11) by another cone and cup bearing (22).
In Fig. 8, go up fix either ratio gear mounting disc (18) at spiral arm (11), along this dish 8 pairs of speed change gear groups are installed evenly, form by a gearwheel (15) and a small gear (16) for every group, internal gear (14) while of wind-force rudderpost cover (12) outer end meshes with 8 speed changer small gears (16) with 8 gearwheels (15) engagement of speed changer, the inner internal gear (17) of blade axle sleeve (13) simultaneously.
In Fig. 9, erect under (surface of revolution is perpendicular to the ground) setting at this steering wheel surface of revolution, except the structure shape difference that does not have base and steering wheel support (1), other parts are identical.If wind direction (25) is when the front, left side blows to steering wheel, 4 wind-force rudders (7) are blown to the right side of surface of revolution entirely, 4 counterweights (10) are all pointed to the direction of the wind comes from left side, 4 blades (5) are 45 degree with the angle of wind direction, and true dip direction unanimity, this moment, the working forms of steering wheel was identical with paddle wheel, and the sense of rotation of steering wheel is constant.
In Figure 10, when wind direction (25) vertically blows to steering wheel surface of revolution in the page outside the page (this moment is identical with the steering wheel working condition that Fig. 9 shows), 4 wind-force rudder counterweights (10) are all pointed to the outer direction of the wind comes from of the page, 4 blades (5) all are in the position with the direction 45 degree elevations angle of the wind comes under the drive of corresponding wind-force rudder (7), and every blade towards the edge of counterclockwise direction one side also outside the page, therefore, every blade all produces the moment of counterclockwise direction (for the steering wheel running shaft), the promotion steering wheel rotates, at this moment, the working forms of steering wheel is identical with paddle wheel.If the Vertical direction of the direction of wind outside the page begin to around any deviation in driction miter angle when blowing to the surface of revolution of steering wheel, then the wind-force rudder drives the working forms that separately blade is adjusted to half paddle wheel and half steering wheel, the sense of rotation of steering wheel is constant; If wind continues to be offset to 90 degree when blowing to the side of steering wheel surface of revolution from above-mentioned miter angle, then the wind-force rudder drives separately blade and adjusts to the working forms of pure steering wheel (this moment, rotating shaft center's line was vertical with wind direction, the steering wheel working condition of showing with Fig. 2 is identical), the sense of rotation of steering wheel remains constant.
In sum, if wind is from the direction vertical with the page, progressively to around any deviation in driction to 90 degree when blowing to steering wheel in the page, steering wheel then experiences one and is progressively become half paddle wheel and half steering wheel, become the process of pure steering wheel working forms again by paddle wheel, this process also can Back Up.Wind blows in the page that situation outside the page is identical with this process (can be with reference to figure 9, but wind direction become blow to the left side from the right side), the sense of rotation of steering wheel is also constant, so, no matter wind blows to steering wheel from which direction, it can continuously rotate toward the direction, and talk about with another sentence: the steering wheel running shaft is on the mounting point of any angle, and it can both proper functioning.
