Louvered fluid power plant of the present utility model can be horizontally disposed with according to axle axial (as shown in Figure 1 to Figure 2) while use, maybe can stand vertically setting (not providing diagram) according to axle axial.But no matter be horizontally disposed with or vertically arrange, the structure of louvered fluid power plant is identical, and work principle be also identical, window leaf 3 is articulated with window outer rim 5.In the time that louvered fluid power plant of the present utility model is positioned in fluid, if any air-flow exist atmosphere in or have current exist waters in, fluid flow direction is crossing with axle axis has formed steering surface 13, described steering surface 13 spatial division following current district 11 and countercurrent zone 12, window leaf 3 on wheel blade 1 in following current district 11 can covered window 4 because of fluid impetus, window leaf 3 on wheel blade 1 in countercurrent zone 12 can open and open window 4 because of fluid impetus, while making the wheel blade 1 adverse current revolution in countercurrent zone 12, reduce resistance, make to be subject to fluid flow function to drive wheel shaft to rotate with outwards continuous outputting power at the wheel blade 1 in following current district 11 simultaneously.

In addition, in the time that wheel shaft 2 is vertically placed, the structure of louvered fluid power plant of the present utility model when adopting with wheel shaft 2 horizontal positioned is identical, can also adopt structure as shown in Figure 12 and Figure 13.As shown in Fig. 1 and Figure 12, both differences are only that window leaf 3 is hinged on the position difference on window 4, and other structures are identical.Continue in conjunction with Figure 12, window leaf 3 is rotatably connected on the side margin of window 4 perpendicular to axle axial, that is, as shown in figure 13, in the time that wheel shaft 2 is vertically placed, window leaf 3 is hinged on the upper window edge 18 of window 4.

Being horizontally placed to working principle and the working procedure of example to louvered fluid power plant of the present utility model below in conjunction with accompanying drawing with wheel shaft briefly introduces as follows:

When use, louvered fluid power plant of the present utility model is placed in to fluid, as the mode of Fig. 1 is placed.

As example describes, as shown in Figure 14 and Figure 15, now these four wheel blades are defined as respectively to wheel blade 1a, wheel blade 1b, wheel blade 1c and wheel blade 1d taking four wheel blades 1 wherein below, and the direction of arrow in Figure 14 and Figure 15 indicates the flow direction of fluid.

As shown in figure 14, wheel blade 1a in following current district 11 turns to while approaching steering surface 13, if a little the convex surface of the window leaf 3 of evagination be still subject to fluid impetus and closing window 4(window leaf 3 not evagination be also the same), wheel blade 1a is rotated further and crosses steering surface 13 and enters countercurrent zone 12, and then as shown in figure 15, the concave surface of the window leaf 3 of wheel blade 1b, in face of mobile fluid, is subject to fluid impetus and naturally opens and open window 4.

Substantially, when wheel blade 1a does not also cross middle vertical plane 14 entering following current district 11, the active force that suffered fluid promotes is the most remarkable, wheel blade 1a crosses after middle vertical plane 14, the active force that promoted by fluid has just weakened, now fluid still can flow according to former flow direction, except gravity, do not have again other masterpiece to be used on window leaf 3, if be placed in water, the material manufacture that window leaf 3 can adopt proportion or effective percentage and water to work as, the suffered gravity of wheel blade 1a and buoyancy of water have been offseted, so wheel blade 1a is crossing after middle vertical plane 14, window leaf 3 still can be by pasting window 4, after all under actual conditions, fluid flow direction perhaps slightly changes, but because window leaf 3 is hinged on freely activity of window outer rim 5, enter countercurrent zone 12 although also do not cross steering surface 13 at wheel blade 1a, window leaf 3 may be because being opened by the fluid force that actual conditions change a little, but can not form the resistance that wheel blade 1a is rotated yet.If be placed in atmosphere, window leaf 3 can be with lighter material manufactures, and window leaf 3 perhaps can open and also can not form the resistance that wheel blade 1a is rotated a little not crossing before steering surface 13 enters countercurrent zone 12.

Again as shown in figure 14, wheel blade 1c in countercurrent zone 12 turns to while approaching steering surface 13, if a little the convex surface of the window leaf 3 of evagination be subject to fluid impetus and semi-closed window 4(window leaf 3 not evagination be also the same), wheel blade 1c is rotated further and crosses steering surface 13 and enters following current district 11, and then as shown in figure 15, the convex surface of the window leaf 3 of wheel blade 1d, in face of mobile fluid, is subject to fluid impetus and is closing window 4.

Because fluid dynamic effect, fluid, constantly like this through louvered fluid power plant of the present utility model, constantly drives wheel blade 1 and then drives wheel shaft 2 to rotate, and seething, to produce kinetic energy, the kinetic energy that wheel shaft 2 produces can outwards be exported for generating.

The energy loss of louvered fluid power plant of the present utility model is mainly in four parts: 1) the mechanical friction power of wheel shaft 2; 2) when wheel blade 1 enters countercurrent zone 12, open the energy that window leaf 3 consumes; 3) when wheel blade 1 turns round in countercurrent zone 12, the real area of wheel blade skeleton 7 stops the energy that fluid consumes; 4) power consumption of the own institute of louvered fluid power plant of the present utility model tool total quality in rotation.

Above four portion of energy losses approach fixing, according to reason, in the air-flow of high wind or under the huge energy active force of river or ocean current, fluid drives wheel blade 1 to rotate produced energy through louvered fluid power plant of the present utility model, far exceed energy loss, offset after energy loss, also have a large amount of dump energies, to drive generator set generating.

That the energy that louvered fluid power plant of the present utility model is produced describes by preresearch estimates below:

The radial length of supposing wheel blade 1 is R, and the axial length of supposing wheel blade 1 is L, and the area of wheel blade 1 is RL.Suppose that the distance time used that fluid flows through r according to steering surface 13 directions is t, liquid speed v=r/t.Fluid density is ρ.

Preresearch estimates power P=(1/2) mv ²/ t=(1/2) ρ rRLv ²/ t=(1/2) ρ RLv ³.

If be placed in current, water density ρ=1000Kg/m ³.

Suppose that R is 1 meter, the long L=1000 rice of wheel blade, water velocity v is 1 meter per second, power P=(1/2) × 1000 × 1 × 1000 × 1 ³=0.5 megawatt.Same device, the current that water velocity v is 3 meter per seconds if be placed in, power P=(1/2) × 1000 × 1 × 1000 × 3 ³=13.5 megawatts.

If be placed in high wind, air density ρ=0.225Kg/m ³.

Suppose that R is 1 meter, the long L=100 rice of wheel blade, when wind speed v is 10 meter per second, power P=(1/2) × 0.225 × 1 × 100 × 10 ³=11.2 kilowatts.Same device, the high wind that wind speed v is 20 meter per seconds if be placed in, power P=(1/2) × 0.225 × 1 × 100 × 20 ³=90 kilowatts.
