The present invention is fit to be installed in the abundant place of wind energy resources, avoid disastrous region,, safe and reliable lightning arrester and earthed system are installed near national grid and load centre, safe and reliable windproof backguy is installed, to prevent the attack of strong wind, strong storm to wind energy turbine set.Described each air duct 6 and internal structure thereof are a cell cube, and each cell cube is pressed workload demand and adopted tower collection formula to install, and form generating field by several, tens or even tens cell cubes; Can be by electric motor power, setting every generator set 15 rated power is 50-1000W, wind wheel blade 1602 diameters are below 1.6 meters, set up into the small power generation field by N micro wind turbine generator group 15; Also can set every generator set 15 rated power is 1-10KW, and wind wheel blade 1602 diameters are 1.6-7 rice, sets up into medium-sized generating field by N small-sized wind power generator group 15; Or to set every generator set 15 rated power be 10-100KW, and rotor diameter is a 7-16 rice, sets up into large-scale generating field by N medium-sized wind power generating set 15; Even can be built into more large-scale generating field by demand.

In order to effectively utilize wind energy, and make wind-force bring into play the big usefulness of wind, output is higher than dropping into, can be in N air duct 6 according to wind power generating set 15 and axial-flow blower were installed in 2: 1 or 4: 1, promptly from bottom to top in two adjacent air ducts 6, a generator set 15 is installed respectively, promptly in the 3rd air duct 6 axial-flow blower is installed thereon then, perhaps in four adjacent air ducts 6, a generator set 15 is installed respectively, promptly in the 5th air duct 6 axial-flow blower is installed thereon then, by that analogy, be assembled into a wind power plant.Axial-flow blower is a prior art, and its effect is to play the effect of blowing that sucts down in air duct 6, to strengthen the wind energy in the air duct 6.

Working principle of the present invention: having under the situation of wind, the flow through wind on ground, through the becalm obstruction in storehouse 10 of rice word or * shape, enter each air duct 6 after the rectification successively, for N wind power generating set 15 in each air duct 6 provides wind energy, the wind wheel blade 1602 that blows wind wheel 16 rotates, and drives generator set 15 generatings; Wind speed reduced when the wake flow of generation was at the space chamber 1301 of flowing through gradually wide after wind is through first wind power generating set 15, blast increases, wake flow is after current plate 12 rectifications, can reduce turbulence intensity, by the air-flow that makes progress in the air duct 6, to upper strata generator set 15 diffluences repeat acting after wind rallies here, repeat to integrate; Simultaneously the surface wind after storehouse 10 rectifications of becalming utilizes toroidal overlay 3 to absorb the cold and heat air that solar energy produce to flow, can increase the wind energy in the air duct 6, and cooperates the 10 pairs of air-flow rectifications set in storehouse of becalming of rice word or * shape, sends into air duct; Blow down the wind of suction on after wind wheel 16 turns round, and after flowing through air duct 6 top cowlings 7 aloft, the wind that the intake grill 601 of air duct 6 enters to produce eddy current, the air-flow that utilizes air swirl to drive in the air duct 6 upwards flows, add the wind that blower 18 blows afloat, can make N the generator set of installing in N the air duct 6 15 be subjected to enough wind energy powers, simultaneously, the wind energy power that the air flows that hour also can utilize each air duct 6 high height that stand and temperature difference to produce at weak wind or wind generates, the auxiliary wind energy of above multichannel can make the present invention reach electricity generation efficiency steady in a long-term.

Because 15 responsible generatings of described wind power generating set according to Bernoulli's law, increase the blast in the air duct 6 of flowing through by force along with the reduction of wind speed, reduce along with the increase of wind speed; And the wind speed of axial-flow blower in air duct 6 is under weak wind or the calm situation, rotate wind wheel blades 1602 through blower 18 running wind wheels 16, electric energy be transformed into mechanical energy regeneration wind energy, by on blow down suction, make to form man-made airflow in the air duct 6, drive 15 generatings of N wind power generating set; When the wind speed that flows through in the air duct 6 reaches and can satisfy the wind speed of wind power generating set 15 stable electric generations in the air duct 6, axial-flow blower is with regard to this changing function, be transformed into wind turbine power generation by the air blast blowing, therefore axial-flow blower also can be substituted by induction generator, induction generator utilizes the external electrical network power supply, start induction generator and rotate wind wheel, be transformed into the wind-driven generator function by motor function, thereby carry out wind-power electricity generation, in the wind speed in the air duct 6 can be kept air duct 6 during other wind turbine power generations, induction generator can cut off the external electrical network power supply, at this moment, induction generator becomes generator by motivation, dual-use, can improve the big efficient of wind of complete equipment operation, improve output usefulness then.
