3, described second driving mechanism is: the gear that actuating motor axle head is installed and servo motor transmission gears meshing, servo motor transmission gear to be arranged on actuating motor fitting seat and to be coaxially connected with a small pulley, the transverse arm drive pulley be coaxially connected with transverse arm drive bevel gear transverse arm is equipped with, connecting cross arm driving belt between small pulley and transverse arm drive pulley.
The utility model provides a kind of liter resistance combined type vertical axis aerogenerator of ACTIVE CONTROL, make wind-driven generator have the feature of lift-type and resistance type blower fan by changing blade folding form simultaneously, and the shortcoming of both lift-type and resistance type blower fan can be avoided by ACTIVE CONTROL, have complementary advantages.Be applicable to any wind regime apparatus for lower wind generating place.
During low wind speed, wind wheel remains static, be installed on having between brush conducting slip ring and tower bar in wheel hub and there is no relative movement, PLC servomotor controller receives slow-speed of revolution signal, PLC servomotor controller sends rotating forward instruction to actuating motor, actuating motor rotates forward and is passed on the leading screw of transverse arm termination by gear, V band by moment, this leading screw is two-way leading screw (left side left-handed, right side dextrorotation), leading screw is arranged symmetrically with two nuts to coordinate with it, leading screw rotates forward two nut spacing and increases, and leading screw two nut spacing of reversing reduce.Minor axis is welded with on the downside of nut, nut is hinged by the perforate on the upside of minor axis and blade, blade profile chooses symmetrical airfoil, and (lift-type wind-driven generator majority adopts this kind of aerofoil profile, this airfoil structure is simple, lift is large, aeroperformance is good), blade is symmetrical dimidiation from middle face, and hinged in large termination, such two halves blade, two nuts, two-way leading screws just constitute an open-and-close mechanism.Two-way leading screw rotates forward, and blade is opened gradually by closed state, and at this moment blade form is C shape, even if its resisting moment of low wind speed is also enough to make wind wheel rotate.
When conducting slip ring detects that wind speed round exceedes the minimum wind speed of lift-type wind-driven generator startup, PLC servomotor controller will pass to actuating motor reverse signal, actuating motor reversion drives the reversion of two-way leading screw, blade closes gradually, wind-driven generator is converted to lift-type fan condition by resistance type fan condition, improves wind energy utilization to greatest extent.
At very high wind speeds, lift-type wind-driven generator may produce stall, tip speed ratio is excessive, the aerofoil profile angle of attack exceedes optimum range, ratio of lift coefficient to drag coefficient reduces, now lift-type wind turbine power generation efficiency can reduce greatly, so when exceeding rated wind speed, PLC servomotor controller also will send positive rotaring signal and blade be opened (resistance type blower fan is due to the large reason of blade windage, wind wheel rotational speed has limit speed, and this limit speed can not be too high, this is also the reason that resistance type wind-driven generator wind energy utilization is low), when wind speed round drops in nominal speed range, blade closes again again.
The utility model makes full use of lift-type wind-driven generator and resistance type wind-driven generator advantage separately, the two is combined, is reached the object of the highest wind energy utilization by PLC ACTIVE CONTROL fan blade form.
Meaning of the present utility model and advantage are:
The utility model is different from prior art, is not structurally resistance type wind-driven generator and lift-type wind-driven generator simply to be superposed, but fixed blade is in the past become mechanical structure.The utility model has the following advantages:
1. can ACTIVE CONTROL leaf morphology, making this vertical axis aerogenerator be lift-type wind-driven generator, is again resistance type wind-driven generator;
2. utilize resistance type wind-driven generator starting torque large, the advantage that threshold wind velocity is low, the minimum work wind speed range of wind-driven generator can be made to reduce;
3. utilize lift-type wind-driven generator aeroperformance good, the advantage that wind energy utilization is high, improves the energy utilization rate of overall wind-driven generator;
4. under utilizing resistance type wind-driven generator height rotating speed, resistance increases the feature that wind speed round is reduced, make up the too high unmanageable shortcoming of lift-type wind-driven generator rotating speed under strong wind, under strong wind, utilize resistance type wind-driven generator form to control in nominal speed range by rotating speed, the band-type brake deceleration system of lift-type wind-driven generator is more reliable than ever.
Compared with vertical axis aerogenerator in the past, the utility model belongs to function and structure innovation, novel in design, and structure is simple, reliable, and control simple, improve work wind speed range and the wind energy utilization of vertical axis aerogenerator, practicability is very strong.
