Embodiment 1
A kind of novel blade, such as Fig. 1 to 3, including upright bar 1, big blade 2, swivel becket 3, the swivel becket 3 is actively set on vertical
On bar 1, the big blade 2 has several, and even circumferential branch is arranged on swivel becket 3, and the big blade 2 is by upper and lower two wind
Leaf frame 21 and several rotatable vanelets 22 being mounted between upper and lower two fan blade frames 21 form, and the fan blade frame 21 is solid
It is scheduled on swivel becket 3, the underside of swivel becket 3 is provided with eccentric wheel 4 in the upright bar 1, the lower section of eccentric wheel 4 in upright bar 1
It is fixed with fixed ring gear 5, is vertically and fixedly provided with wind direction board 6 on the eccentric wheel 4.
The vanelets 22 are connect by connecting rod 23 with the push rod 24 for being located at downside 21 side of fan blade frame, the push rod 24 1
End is connected with push-rod wheel 26, the central axes of the push-rod wheel 26 and the axis parallel of eccentric wheel 4, push rod by push the spring 25
Wheel 26 is close together under the action of push the spring 25 with 4 edge of eccentric wheel.23 one end activity of connecting rod is inserted in vanelets
22 it is following on, 23 other end activity of connecting rod is inserted on push rod 24.24 activity of push rod, which is located at, to be arranged on 21 side wall of fan blade frame
Fixing groove 27 in.Fixing groove 27 at 21 external end head of fan blade frame be " [", remaining is L shape.On the wind direction board 6
Level is equipped with spring pin 7, and the cone-shaped end level of the spring pin 7 is inserted in the tooth socket of fixed ring gear 5.The vanelets
22 shaft is arranged on side elevationally outward, and the shaft upper and lower ends activity is inserted on two fan blade frames 22 up and down.The wind direction board 6
Under push-rod wheel 26.
A kind of application method of the novel blade are as follows: when wind direction board is vertical with the direction of wind, wind blows wind direction board,
Wind direction board band movable eccentric wheel turns to that wind direction board is parallel with wind direction, on the tip and fixed ring gear of the spring pin on wind direction board
Tooth socket occlusion, eccentric wheel is fixed, and when the wind-force on wind direction board, which reaches, is enough that spring pin is allowed to bounce, wind direction board drives eccentric
Wheel is rotated to suitable position；Push-rod wheel is close together under the action of push rod spring with eccentric wheel, and can be around eccentric rotation
Dynamic, when big blade is rotated around upright bar, push rod is also rotated with it, and the vanelets on that face big blade rotated with the wind are by push rod
The vanelets on that face big blade for pushing and spelling knot together, and rotate against the wind are pushed by push rod to be separated from each other, and is formed
Gap.
Use principle of the invention are as follows: each big blade is made of several vanelets, and vanelets can be in the work of push rod
With appropriate angle rotating folding under, there is push-rod wheel in push rod one end, and push-rod wheel is close under the action of push rod spring with eccentric wheel
Together, it and can be rotated around eccentric wheel, when big blade is rotated around upright bar, the leaflet on that face big blade that rotates with the wind
Piece spells knot together, and the vanelets on that face big blade rotated against the wind are separated from each other, and forms gap, reduces resistance.In order to
Adapt to wind direction, devise wind direction board, the farthest point and closest approach line vertical welding knot of wind direction board and eccentric wheel, so no matter wind direction
How to change, the farthest point of eccentric wheel and closest approach line are laterally vertical with wind direction always, it is ensured that big blade is in wind direction cross section
Small upper blade just merges or just opens.It does not prevent low-angle from disorderly putting to adapt to wind direction again, and designs fixed ring gear and be located at
Below eccentric wheel, design has spring pin on wind direction board, and pin tip is engaged with tooth socket, is enough to allow when the power on wind direction board reaches
When spring pin bounces, wind direction board band movable eccentric wheel is rotated to suitable position, achievees the purpose that adapt to wind direction.The structure maximum limit
Degree ground utilizes the kinetic energy of wind, hereby theoretical according to shellfish, if V1It is the wind speed of wind wheel upstream, V is the wind speed by wind wheel, V2It is wind wheel
The wind speed in downstream, the flow area by wind wheel are S, and ρ is atmospheric density, since wind wheel energy obtained is by wind energy transformation
It obtains, so V2It is necessarily smaller than V1.By the equation of momentum, the aerodynamic force on wind wheel can must be acted on are as follows:
F=ρ SV (V1-V2)
So the power that wind wheel absorbs is
P=FV=ρ SV2(V1-V2)
Therefore the variation of upstream to downstream kinetic energy is △ E=0.5 ρ SV (V1 2-V2 2)
By law of conservation of energy, it is known that
V=0.5 (V1+V2)
Therefore, the power of the aerodynamic force and offer that act on wind wheel can be written as
F=0.5 ρ S (V1 2-V2 2)
P=0.25 ρ S (V1 2-V2 2)(V1+V2)
For given upstream speed V1, can be written with V2For the changed power relationship of function, above formula differential can be obtained into V2=
V1When/3, power P reaches maximum value, i.e. Pmax=8/27 ρ SV13
So controlling in fan operation by intelligent speed changing, make fan blade rotation close to V1When/3, so that transfer power P
Reach maximum value.This equipment is used cooperatively with intelligent transmission, so that fan blade revolving speed is kept reasonably stability, to obtain maximum efficiency.
Embodiment 2
Such as Fig. 4, the present embodiment is to make a pair of of the big blade the being oppositely arranged vertical view be in the production camber on one side of fan blade frame
Serpentine installs edge additional around fan blade frame arc-shaped side, and small fan blade is arranged along the edge of fan blade frame arc-shaped side, connects shape
At circular hood, wind energy transformation rate is improved.
Embodiment 3
Such as Fig. 5, the present embodiment is several small fan blades replaced on each big blade with canvas, the fan blade frame of each big blade
On be respectively mounted canvas reel, principle is such as steel tape, and vertical edges are equipped with fixed upright bar, fixed upright bar upper and lower ends on the inside of canvas
It is fixed on fan blade frame, canvas reel is arranged in activity upright bar, and activity upright bar upper and lower ends are located at the loose slot on fan blade frame
Interior, activity upright bar lower end is connect with connecting rod, and the activity of connecting rod one end is inserted on push rod.So canvas can be under the action of push rod
Open or crispatura, with the rotation of big blade, under the action of eccentric wheel, push rod moves back and forth, such cloth sail with the wind when
It opens, when contrary wind crispaturas, and can get maximum wind-force in this way.
Embodiment 4
Such as Fig. 6, the present embodiment is that several apertures are opened on every big blade, and minor flaps are arranged by hinge on aperture,
Guarantee to blow afloat when contrary wind when fan blade rotation, with the wind when Natural closure under gravity, such fan blade obtains maximum forward power
Square, natural adaptation wind direction, the present embodiment do not need wind direction board, eccentric wheel, fixed ring gear, spring pin, connecting rod, push rod, promotion
Spring, push-rod wheel, fixing groove, structure is simply direct, high conversion rate.
