Each blade unit 32 is connected to corresponding installation portion 312, and with it is several around horizontal axis H and each other The blade module 33 at angle interval.Each blade module 33 extends generally towards a radial direction of the rotating shaft 31, and has One grid 34 for connecting the rotating shaft 31, and several blades 35 for being installed on the grid 34.The blade module 33 of the present embodiment Quantity is three, and the grid 34 of the blade module 33 is in 120 degree of angle intervals to each other, but in implementation, the blade module 33 quantity also can be two, four or more than five.In addition, the quantity of the blade unit 32 also can be four or more than six even number number Amount, and the installation portion 312 is respectively arranged at symmetrically to each other, it is not limited with the present embodiment.

There is each grid 34 several radial directions along the rotating shaft 31 to be spaced and all along the one of the rotating shaft 31 The airfoil cascade bar 36 of axial direction extension, and several auxiliary for being spaced along the axial direction and all extending along the radial direction Grid bar 37, the airfoil cascade bar 36 are interweaved with the hack lever and define the blade space 38 of several matrix arrangements jointly.

Each airfoil cascade bar 36 is extended with one in the cross section 361 of wing shape.The cross section 361 is included along this radially The spaced medial extremity 362 in direction and an outboard end 363, one are by the linear extension of medial extremity 362 to the outside The flat side 364 at end 363, and one by the medial extremity 362, smoothly curved arc extends to the outboard end 363 and towards the rotation direction The convex side 365 of arc of T protrusions.There is the convex side 365 of the arc one to be increasingly towards the extension of rotation direction T curved arcs by the outboard end 363 To the outer arc segments 366 of a turning point 367, and an inner arc that the medial extremity 362 is extended to by the 367 gradual curved arc of turning point Section 368.The turning point 367 is farthest of the convex side 365 of the arc relative to the flat side 364.The interior segmental arc 368 is along the radial direction side To development length L1 be more than the outer arc segments 366 development length L2.

The blade 35 is arranged in arrays and corresponds to the blade space 38 respectively, and each blade 35 is remote with one The rotating shaft 31 and the connection end 351 for connecting the grid 34, and the swinging end 352 of a neighbouring rotating shaft 31, each blade 35 The blade space 38 can be covered at one and the swinging end 352 is reclined the closed position of the grid 34, and one makes the pendulum Moved between open position away from the grid 34 moved end 352.

Refering to Fig. 2, Fig. 4 and Fig. 5, the utility model stream power blade apparatus is in use, to pass through the trunnion axis of the rotating shaft 31 Line H makees to demarcate, and two blade modules 33 of the lower section of rotating shaft 31 are then located at the reverse blast side of lee face, at the same time, The blade module 33 of the top of rotating shaft 31 is in the forward blast side of windward side blast.The blade module 33 of top is by edge During one flow direction F1 fluid forces, because the blade 35 of the blade module 33 is located at the windward side of grid 34, meeting Blown and abutted on the grid 34, and positioned at the closed position and cover blade space 38, the blade 35 so that with this Grid 34 is arranged in pairs or groups, and a complete surface windward is collectively formed in the windward side, and underlying two blade modules 33, then The grid 34 can be pushed away by fluid, and be located at the open position, enable fluid via the blade space 38 by by described The keying of blade 35 is engaged, and can be produced larger torsion rotation, be enable the utility model by Wind power propelling and together with this turn Axle 31 rotates towards rotation direction T together.

Meanwhile the airfoil cascade bar 36 of each blade unit 32, ad-hoc location by flow of fluid by when, meeting Producing one makes corresponding installation portion 312 towards the biasing force deflected in contrast to flow direction F1, as shown in figure 5, the airfoil cascade When bar 36 is located at lower left position, the blade 35 of the blade module 33 can be moved to the open position, pass through the airfoil cascade The shape design of bar 36, it is very fast to flow through the rate of flow of fluid of the convex side 365 of arc of the airfoil cascade bar 36, flows through the airfoil cascade bar 36 Flat side 364 rate of flow of fluid it is slower, and can be known according to Bernoulli law, the faster pressure of rate of flow of fluid is smaller, therefore the wing Type grid bar 36 can produce one towards upper left lift, also can just form the biasing force P toward opposite flow direction F1.

Refering to Fig. 5 and Fig. 6, when the airfoil cascade bar 36 produces biasing force P, the installation portion of the both sides of rotating shaft 31 can be driven 312 scratch relative to the fulcrum 311 towards in contrast to flow direction F1 is curved, make the rotating shaft 31 that curved arc shape be presented, by above-mentioned Shape, the blading 3 can be made to be stably maintained at the wind-swept place.

Refering to Fig. 5, Fig. 6 and Fig. 7, when fluid is converted into flow direction F2 by flow direction F1, the meeting of deflector 22 By fluid forces, and produce one and drive the rotation seat 1 to drive the deflecting force R that the blading 3 turns to the wind-swept place, Turn to solid line position of the blading 3 from Fig. 7 imaginary line position along arrow A directions toward Fig. 7, with the blading 3 Turning to, the contact area of the blade module 33 and fluid can increase, and by the drag with deflecting force R opposite directions, connect , the airfoil cascade bar 36 with the contact area of fluid as can increase, and produce toward opposite flow direction F2's Biasing force P, and the deflecting force R of the deflector 22 is aided in by biasing force P, drag caused by fluid can be overcome, to drive The rotation seat 1 rotates, and the blading 3 is turned to such as the wind-swept place of Fig. 7 solid lines, consequently, it is possible to pass through biasing force P's Auxiliary, can aid in the blading 3 to turn to the wind-swept place.

Supplementary notes, in the present embodiment, the quantity of the airfoil cascade bar 36 of each grid 34 is three, but is implemented The quantity of the upper airfoil cascade bar 36 also can be two, four or more than five, and each grid 34 also can only have an airfoil cascade Bar 36, is not limited with the present embodiment.

In summary, the utility model stream power blade apparatus, designed by the shape of the airfoil cascade bar 36, can be in fluid By when, produce the biasing force P toward opposite flow direction F1, whereby, the deflecting force R that the deflector 22 is provided is with regard to energy Reduce, and being engaged by deflecting force R and biasing force P, the blading 3 is turned to the wind-swept place, such one Come, the size with regard to the deflector 22 can be reduced, to save the material cost of the group stream power blade apparatus.

Further, since the airfoil cascade bar 36 is exactly the grid 34 of the blade module 33 originally so that the airfoil cascade bar 36 Dimensions length can with the blade module 33 size increase and increase, therefore, when user increases institute in order to improve torsion When stating the size of blade module 33, the dimensions length of the airfoil cascade bar 36 can also increase, and can provide larger biasing force, come The deflecting force of the deflector 22 is aided in, can reduce increase the material needed for the deflector 22 so as to reduce cost whereby, really can Reach the purpose of this utility model.

As described above, embodiment only of the present utility model, when can not be limited with this utility model implementation Scope, i.e., all simple equivalent changes and modificationss made according to the utility model claims book and description, all still belongs to The scope of the utility model.
