The characteristics of the technical program includes following aspect；One, which is selected, folds maple leaf mechanism to substitute common fan blade, further Reduce windage；Two, are become air in compressed air indentation storage filling by making-up air device, to realize pushing turbine high speed Rotation drives electrical power generators；Three, use tower air accumulator, and storage energy extends the working time of steam turbine, improves wind energy Utilization rate；Four, steam turbines use the direct-firing steam turbine of single blade, and the direct-firing steam turbine of single blade is different from common steam turbine, it Using single blade blow-through structure, structure is simple, saves the energy, and torque is big, and revolving speed is high；Five, generators use wind energy turbine generator Machine, issue electricity be standard three phase sine alternating current, without any power transformation conversion process can be used directly with it is grid-connected.

In the technical scheme, using fan blade mechanism is folded, main purpose is to eliminate the wind wheel rotation of vertical axis windmill When contrary wind period apoplexy resistance.(blowing wind into the resistance abbreviation windage that fan blade is encountered).In the operational process of wind energy conversion system, wind speed The front and back of fan blade can be blown into simultaneously, and positive wind speed is named as with the wind, and can generate motive force with the wind makes fan blade around wind Wheel shaft rotation, and the fan blade back side can also generate an equal amount of power opposite direction wind speed, be named as against the wind, generate power against the wind As windage, the resistance in blade rotary motion is formed, the power of the bigger wind energy conversion system of resistance is inversely proportional with regard to smaller, just should be this Sample, blade design are concave surfaces at front, and the back side is the resistance that smooth convex surface reduces wind, and wind wheel motion principle is that front wind pressure subtracts (back side wind pressure is multiplied by air resistance coefficient 0.5) is gone to be equal to difference, so wind wheel can be to power under the conditions of establishment both sides fan blade power is uneven Big direction rotates, and the power of difference more big blade is bigger, and power size is related with wind speed pressure and fan blade size.For Reduction windage is selected and folds fan blade mechanism, and two panels leaf is of different sizes, inner sheet leaf is more longer than outer plate leaf, fan blade rotate to from When opening the contrary wind period, wind blows longer fan blade, and longer leaf natural can be pivoted, and two gears of blade shaft drive another survey Vanelets open simultaneously fan blade.It, can be on longer blade rotor in order to avoid blade opening is not in place since the power of opening is small Disc spring is set, has disc spring that longer blade auxiliary is assisted to open.Fan blade is logical by ac motor when rotating to before the contrary wind period Crossing screw rod pushes position-limited rack so that fan blade is closed, and the area at the diminution fan blade back side, the whole basic streamlining of fan blade body hinders Force coefficient reaches the optimum efficiency for reducing contrary wind resistance less than 0.2, this structure reduces resistance and increases power.Since fan blade closes Disc spring generation property becomes when closing, so fan blade can be in wind-force and disc spring when ac motor driving position-limited rack moves back and decontrols fan blade Double action under open, to effectively evade windage, reduce air resistance coefficient.By original fan blade arc convex surface resistance coefficient 0.5 Be reduced to 0.2, reduce the loss of contrary wind period windage, the power of wind wheel can be improved 30%, the utilization rate of wind energy reach 80% with On.In order to preferably reduce from force coefficient, folding fan blade mechanism speed regulation can be used electrical control method, by ac motor and The cooperation of screw rod drives position-limited rack mobile, and then controls fan blade opening and closing movement.The controllable wind-engaging of fan blade opening degree The size of area, fan blade opens larger folding fan blade mechanism revolving speed will be quicker, opens a little bit smaller folding fan blade mechanism and turns Speed is just slow, and speed regulation effect is reached under the wind of varying strength.Fan blade movement is controlled by ac motor, so as to root Make to fold fan blade mechanism realization variable speed according to actual needs, the utilization rate 15-20% of wind energy can be improved.It is drawn by motor threaded rod Dynamic limiting bracket adjusts fan blade opening degree, and the safe condition that wind wheel stops braking being played when thoroughly closing.All motors of fan blade Power control circuit is parallel, and 220V two-phase 150-200W decelerator [26] is easy to operate, securely and reliably, Loading onto remote control device can be compared with far distance control.This structure is suitble to H resistance-type high-power vertical shaft wind-force wind-driven generator to make With.

In the technical scheme, making-up air device will fold fan blade mechanism large torque power and be transmitted by crankshaft and crankshaft wheel hub Air compression cylinder is given, so that the connecting rod piston of air compression cylinder be driven to move reciprocatingly, piston is pushed ahead compressed air and reached Exhaust check valve is opened when authorized pressure, and compressed air extrusion cylinder is passed to tower air accumulator.The characteristics of making-up air device is It is concentrated use in after air trapping being got up to reach regulation air pressure at several revs/min of the wind wheel slow-speed of revolution.Tower air accumulator Compressed air enters vacuum tank by pipeline when interior compressed air reaches 0.2MPa, is formed subsequently into flow control valve stable High pressure draught finally enters steam turbine drive rotor high speed rotation.

In the technical scheme, steam turbine uses the direct-firing steam turbine of single blade.The reason is that the steamer that conventional formula is common Machine is to be not suitable for the unstable area of wind speed and pressure using the steam turbine of heavy caliber, large flow-rate gas stream.And the direct-firing vapour of single blade The compressed air of 4.1m3/h can be discharged in turbine in the case where several turns when 0.1MPa, its advantage is that gas consumption is small, self resistance is small Loss is few, and structure is simple, and lightweight is small, and the big revolving speed of torque is high, and the steady less energy-consuming of revolving speed, low pressure can work normally, and needs 0.1MPa compressed air revolving speed can reach 750 revs/min, and revolving speed reaches 1546 revs/min and reaches normal operating conditions when 0.2MPa, supply Revolving speed required for atmospheric pressure can be controlled when high by vacuum tank and flow control valve, the direct-firing steam turbine energy band of single blade The three-phase synchronous AC generator of dynamic 10kw issues normal voltage 400V, electric current 18.1A, 50HZ simple alternating current electric energy directly makes With it can drive 3 3kw motor to work at the same time.Suitable rural household electricity utilization, which is heated up water, cooks, warms oneself, and farmland water lift pours field filling It irrigates.Herdsman cuts up with a hay cutter grass, crushed feed etc..When steam turbine does not need power generation, other power can also be done and directly used.

In the technical scheme, wind energy is stored using tower body formula air accumulator, can effectively extends the working time of steam turbine, The compressed air of about 1MPa/1m3 drives the power generation function of 10kw to extend 1 hour and works normally, and the air accumulator of 10m3 can extend It works within generator 10 hours, if making several air accumulators, strong wind day stores a large amount of compressed air, and calm day can continuously be sent out more Electricity, it is economical, improve the utilization rate of wind energy.

In the technical scheme, generator has many advantages, such as that high revolving speed, revolving speed are steady, and adaptable standard three-phase alternating current is synchronous Common generator, price are the 1/10 of low-speed permanent-magnet exchange wind turbine, and high speed alternator torque is small, and revolving speed is high, is applicable in pressure Contracting air steam turbine matches power.Cost of electricity-generating reduces, and big small-sized wind power generator can issue the sinusoidal ac of standard, electricity The alternating current for pressing 400V, frequency 50HZ directly uses and simultaneously completely without complex processes, the electric energy of sending such as power transformation conversions Net.Whole compare than old-fashioned wind energy conversion system frequency conversion with novel wind power turbine generator saves cost 1/10th.

Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art The principle of the present invention is embodied to some variations that some of them part may be made, belongs to the scope of protection of the present invention it It is interior.
