Embodiment
The purpose of this invention is to provide a kind of simple in structure, with low cost and flow energy collection method and device, therefore, technological scheme related in the existing technology is improved and improved with greater efficiency.In existing wind power generating set with vertical shaft, not only the angle of blade is changeless, and sharf also is perpendicular to the ground; Like this, along with the rotation of blade may receive negative moment, in addition; Since wind speed with the distance dependent apart from ground is set, so overhead high more then available effective wind speed is just big more; That is to say, more effective in the eminence lower of blower fan.For fear of the generation of this situation, adopt the technological scheme of improving and optimizing in the present embodiment, please refer to accompanying drawing 2, arrow is depicted as the direction of the wind comes among the figure; This wind is to wind energy plant, and this device is a kind of aluminium bamboo structure vertical shaft wind energy device, and main structure is still comparatively similar with existing technology, is made up of main shaft 1, main shaft wheel 11, blade 3, sharf 4, blade arbor wheel 41; Blade 3 is a main structure with bamboo structure, and support and cross bar are that aluminum alloy material is a main structure, and main shaft 1 promptly is the line shaft that drives generator; The main shaft wheel 11 in addition that is connected with main shaft 1, main shaft wheel 11 is fixed rotatable, with the main shaft concentric; Blade arbor wheel 41 is connected with sharf 4, but 41 rotations of blade arbor wheel with around main shaft 1 revolution, blade 3 is connected on the blade arbor wheel 41; The effect of blade 3 is that being used for wind energy transformation is mechanical kinetic energy, and blade 3 is fixed on the sharf 4, the blade arbor wheel 41 in addition that is connected with blade 3; Have cross bar 2 between main shaft 1 and the sharf 4 and carry out structure and be connected, can directly be in transmission connection between main shaft wheel 11 and the blade arbor wheel 41, also can be in transmission connection with transmission part 42; When 3 last times of wind active force blade, will produce a moment, if resultant couple is non-vanishing; Whole device will rotate, and like this, whole device can get into smooth under wind action power.
In order to illustrate in greater detail working principle; Defined the position of four blades 3; As shown in Figure 2, defined the position of four blades 3, be respectively position A, position B, position C, position D with respect to the direction of the wind comes from; Wherein position A is the most approaching position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 0 degree with the angle of the wind comes from; So, position B is approaching position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 90 degree with the angle of the wind comes from; Position C is away from the position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 180 degree with the angle of the wind comes from; And position D is approaching position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 270 degree with the angle of the wind comes from.
In order to make blade bring into play maximum effect as far as possible, utilize wind energy more fully, make the main shaft wheel 11 and the girth ratio of blade arbor wheel 41 be 1:2; Like this, when main shaft 1 rotated, blade wheel shaft 41 formed revolution around main shaft wheel 11 at blade 3; Simultaneously, owing to be in transmission connection with transmission part 42 between main shaft wheel 11 and the blade arbor wheel 41, or directly be in transmission connection; So; Blade arbor wheel 41 can produce rotations, because the girth of main shaft wheel 11 and blade arbor wheel 41 is than being 1:2, so the angular velocity of rotation is 1/2nd of revolution angular velocity.
Like this, blade in different positions just with the different angles that facing the wind of the wind comes from, below with regard to blade 3 respectively in the position situation of A, position B, position C, position D explain; It is as shown in Figure 2,, and can clearly see among Fig. 3, Fig. 4, Fig. 5, Fig. 6; Position A is the most approaching position of the wind comes from; This moment, the cross bar 2 of blade 3 was 0 degree with the angle of the wind comes from, and blade 3 is 45 degree with the angle of the wind comes from, and is as shown in Figure 3; Position B is near the position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 90 degree with the angle of the wind comes from, and blade 3 also is 90 degree with the angle of the wind comes from, and is as shown in Figure 4; Position C is away from the position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 180 degree with the angle of the wind comes from, and blade 3 is 135 degree with the angle of the wind comes from, and is as shown in Figure 5; And position D is near the position of the wind comes from, and this moment, the cross bar 2 of blade 3 was 270 degree with the angle of the wind comes from, and blade 3 is 180 degree with the angle of the wind comes from, and is as shown in Figure 6.
Like this, blade 3 can produce positive moment except D can not produce the positive moment in the position in other position, and particularly in the position during B, the positive moment of generation is maximum.
Device among this embodiment can also be horizontal, that is to say that main shaft 1 is parallel to the ground, and vertical with the direction of the wind comes from, and so at this moment can also utilize ground effect to produce lift.
In addition, can find out that when this embodiment received the wind-force rotation, sense of rotation was rotation counterclockwise by Fig. 2; And the sense of rotation of blade 3 is clockwise, again because in the suffered wind-force maximum of the outermost edge of blade 3, so blade 3 itself receives an anticlockwise moment; In the opposite direction with turning clockwise of blade 3, just, may produce the possibility that a moment is offset in this case; So just might reduce the Wind Power Utilization efficient of whole device, produce for fear of this situation, in the present invention; Make blade 3 have a curved surface wind-guiding face, like Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, and the main axis rotation of the summit sense of rotation of the curved surface wind-guiding face of blade 3 and wind energy plant is in the opposite direction; Like this, in the present embodiment, the suffered wind-force of the outermost edge of blade 3 can be less than the wind-force of inward flange; Just the situation of moment can not occur, and can produce a clockwise running torque, make device move balance and efficient more.
Can find out that thus blade 3 is revolution counterclockwise, rotation clockwise in this case, and is opposite each other, and do not have negative moment; If blade 3 revolution sense of rotation are clockwise, then blade 3 rotation sense of rotation also are to become on the contrary counterclockwise, and are opposite each other.Thereby blade 3 presents centrosymmetric structure for main shaft 1 axle center and distributes.
Simultaneously, for efficient more be suitable for manufacturing, described blade 3 has curved surface wind-guiding face, and is the curved surface of quadratic curve structure, this curved surface wind-guiding face is with respect to the horizontal section structural distribution that is centrosymmetric.
In addition, under normal circumstances, the cross bar 2 between each main shaft 1 and the sharf 4 is two; Such structure is comparatively stable, but also comparatively complicated, and can have influence on Wind Power Utilization efficient; Thereby, also can be that the cross bar 2 between each main shaft 1 and the sharf 4 is one, cross bar 2 is connected in the central region of sharf 4; This spline structure is simpler, and Wind Power Utilization efficient is higher, and outward appearance is also more good-looking.
Directly transmission between aforesaid main shaft wheel 11 and blade arbor wheel 41 also can connect through transmission part 42, and transmission part 42 is for flexibility is in transmission connection, and this flexible transmission part is chain or belt, in particular for Timing Belt.
Simultaneously, described main shaft wheel 11 also can be positive drive with transmission part 42 between the blade wheel shaft 41 and is connected, and these positive drive parts are gear, when adopting the geared parts Placement, can have middle equipment gear.
Like this, the angle that facings the wind of this Wind Power Utilization device is changing always, blade 3 through sharf 4, blade arbor wheel 41 by transmission part 42 and main shaft 1, main shaft wheel 11 drives; Make blade 3 when main shaft 1 rotates a circle, blade 3 is around the sharf 4 rotation half cycles of self, like this; In all positions; Blade 3 is in the state of doing positive work all the time, forms positive moment of torsion, and it can be farthest in face of wind direction; The blade that overcomes existing blower fan is done the state of negative work in some position, improve wind energy utilization.
In addition, this device can reach same even better effect when horizontal use, as shown in Figure 7.
And, because blade 3 has curved-surface structure, can avoid the generation of negative moment, very useful to improving Wind Power Utilization efficient.
Again because blade 3 is to be processed by bamboo material; Have good toughness, the life-span is long, cost is low and the characteristics of environmental protection; So can satisfy goal of the invention of the present invention and reach expection and produce effect, and have simple in structure, start the characteristics that wind-force is little, efficient is high, be easy to safeguard.
The above embodiments are not only a kind of wind-driven generator, more can be wind-driven devices, can be that wind energy water pump, wind energy air pump, wind energy grinding machine, wind energy refrigeration machine, wind energy heat various power plant such as machine, wind energy mechanical energy machine.
Though part preferred embodiment of the present invention only has been described, its meaning and unrestricted scope of the present invention, applicability and configuration here.On the contrary, the detailed description to embodiment can make those skilled in the art be able to implement.Will be understood that not departing under the definite spirit and scope of the invention situation of appended claims, can make suitable change and modification some details.
