Embodiment

The power plant of the rectilinear wind gathering cover wind-power electricity generation powerplant module shown in Fig. 1 and Fig. 2 comprise main shaft 1, wind wheel and wind gathering cover, and main shaft 1 bottom connects speed changing structure 2 and generator set 3.

Wind wheel comprises multi-layer impeller, every 3 layers of impeller are a repetition superpositing unit, 4 identical blades 4 and circular clamping plate 5 between layers that every layer of impeller arranged by equilibrium form, blade 4 is fixing by the clamping plate 5,6 of its above and below, 90 of angle degree between blade 4, blade 4 between the adjacent impeller layer 30 degree angles of staggering, alter wind and reduce operation noise thereby make not produce between impeller layer by clamping plate 5,6.The number of plies of impeller and diameter can be according to size and the generating make out the scales of fabricating yard.Every 1-2 the circular clamping plate 8 of top and circular clamping plate 9 of below that repeat superpositing unit are connected a

unilateral bearing

14,15, and the inner of unilateral bearing 14,15 connects main shaft 1.Impeller passes to main shaft 1 by unilateral bearing 14,15 by rotating power, make the rotation of main shaft 1 produce motive force, in the situation that any one impeller hierarchical element breaks down, other repeats superpositing unit and generator set still can run well, and does not also affect other hierarchical element and run well during maintenance.

Blade 4 is for being parallel to the cambered surface of main shaft, its cross section is semi-cylindrical shaped or L shaped preferably, if the blade profile of Fig. 2 is semi-cylindrical shaped, the blade profile of Fig. 3 is shaped as L shaped, the blade profile of Fig. 4 is that corner is the L shaped of circular arc, this selection of blade can make the center of effort of wind-force near outer end, thereby utilizes to greatest extent wind-force, makes main shaft produce larger torsion.

Larger in the situation that, can increase rotor diameter, select wind wheel as shown in Figure 5 and Figure 6, each impeller layer consists of 6 blades, and its blade shape is consistent with the impeller of Fig. 2, Fig. 3, Fig. 4 respectively; When wind-powered electricity generation is larger, can select larger rotor diameter, use as the wind wheel of Fig. 7 and Fig. 8, each impeller layer consists of 8 blades, and its blade shape is consistent with the impeller of Fig. 2, Fig. 3, Fig. 4 respectively; Can also use by that analogy each impeller layer by 8 wind wheels that form with upper blade, its blade shape is consistent with the impeller of Fig. 2, Fig. 3, Fig. 4 respectively.

Wind gathering cover is 4

wind deflectors

16, 17, 18, 19, each wind deflector 4 comprises two wind-guiding

faces

20, 21, two wind-guiding

faces

20, 21 are plane shape, wherein the first wind-guiding face 20 is positioned at wind wheel radially, its the inner 22 is near the running orbit of the outer end of blade 4, the outer end 23 of the second wind-guiding face 21 connects the outer end 23 of the first wind-guiding face 20, its the inner 24 is near the running orbit of the outer end of blade 4, center line between the first wind-guiding face 25 of two the first wind-guiding faces 20 and another wind deflector, the inner 22 of the first wind-guiding face 20 and the inner 24 of the second wind-guiding face 21 can be by 26 sealings of circular arc panel, 4 wind deflector equiblibrium mass distributions are in the outside of wind wheel.

Shown in Fig. 9, in the situation that there is no the utility model wind gathering cover, wind direction as shown by arrows, the blowing area that blows to wind wheel is less than half and can be able to promotes wind wheel rotation and become power wind b, being greater than in addition half can stop wind wheel rotation to become resistance wind a, the utility model wind gathering cover just hides resistance wind position, and resistance wind guiding is become to power wind.Simultaneously, because wind gathering cover air port area is far longer than the wind-exposuring area of wind wheel, wind gathering cover forms and is subject to wind-tunnel to become pressure wind regime on wind wheel, and the outputting power of wind wheel is increased considerably, and therefore only needs 1-2 level wind just can make wind wheel have enough power to drive generator set.

Wind gathering cover is fixed by fixed support, and four pin land, very firm, can according to wind-powered electricity generation scale need and place situation by stretching wind deflector, to change wind gathering cover big or small.Main shaft 1 supports and is fixed on the support bracket fastened upper and lower of wind gathering cover by bearing 27,28, middle part can be used a plurality of bearings 29 main shaft 1 to be fixed on to the fixed support (shown in Fig. 1) of wind gathering cover, prevent that swinging from appearring in main shaft 1 rotation process, make wind wheel work definitely firm, a wire netting or nonmetal net 30 can be wrapped up in the outside of wind gathering cover and top, prevent that birds, people and animals from entering wind wheel, the utility model is safe and reliable thus.The utility model needs to increase rotor diameter according to scale, increases wind wheel blade, and extends stretching, extension wind gathering cover increase wind-receiving face, improves and reaches required moment of torsion.Wind wheel material selection stainless steel materials or hot galvanizing plate connect combination with screw, and wind wheel support is Steel Support.Wind gathering cover material, small-sized sheet metal or the plastic plate selected made wind gathering cover by support, large and medium generator group can civil structure or reinforced concrete construction make wind gathering cover.
