Description
Technical field
The utility model relates to a kind of novel wind power generating set, and specifically a kind of wind power generating set with the gradually expansion type wind gathering cover belongs to the technical field of wind power generation of new energy.
Background technique
In recent years; Domestic more options annual mean wind speed is that the above high wind speed district of 6m/s sets up large-scale MW class wind turbine group; And average annual wind speed is the low wind speed district of 3-5m/s; Wind speed is little and unstable, does not reach large-scale wind field addressing requirement, and the fine occasion of middle-size and small-size wind power generating set is used in these zones just.
General three blade blower fans and the efficient permanent magnet low-speed generator of adopting of small capacity wind power generating set is equipped with the direction of yaw system with the adjustment blower fan again at present high performance.
The wind power generating set of wind gathering cover form; Its wind gathering cover is tapering type design, and the windward side size is big, and impeller is contained in exhaust outlet; It requires the wind gathering cover longitudinal size longer; And must be equipped with driftage machinery and control system thereof, structure is complicated, and the entire work process yaw system must real-time working.This wind power generating set starts wind speed higher (3m/s or more than), and impeller diameter is bigger, complex structure, and economic benefit is lower.
Summary of the invention
The utility model provides a kind of wind power generating set of novel band gradually expansion type wind gathering cover, and this generator set can breeze wind, from motion tracking wind direction, the operation of wide wind speed range, and possesses high wind energy utilization and reliability.
The technological scheme that provides according to the utility model; The wind power generating set of band gradually expansion type wind gathering cover comprises turning axle, controller, blower fan pylon, cabin, efficient permanent magnet low-speed generator, mechanical brake; Efficient permanent magnet low-speed generator and mechanical brake are installed in the cabin, and turning axle is installed on the blower fan pylon top, and controller is installed on blower fan pylon bottom or indoor; Characteristic is: impeller is installed on wind gathering cover and facings the wind mouthful and be fixed on the cabin; Be connected with the wind gathering cover support on the cabin, the wind gathering cover support is in order to fixing gradually expansion type wind gathering cover, and the gradually expansion type wind gathering cover is installed on the supporting frame; Lightning conductor is installed in the top of blower fan apical support frame, and the center bearing bracket that stretches out from the cabin is installed on the turning axle.
As the further improvement of the utility model, said gradually expansion type wind gathering cover is shaped as flaring circular cone annular.
As the further improvement of the utility model, said gradually expansion type wind gathering cover exhaust outlet is provided with a ring wind gathering ring.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can adapt in the work of low wind speed district, can be used for the low wind speed district that large-scale megawatt wind power generating set can not be moved; Also can be installed on simultaneously between the wind power generating set of existing wind field, and not influence the normal operation that has the wind field unit now, thereby can improve the wind-power electricity generation amount of wind field unit area, further improve wind energy utilization; Can breeze wind, from motion tracking wind direction, the operation of wide wind speed range (2.5m/s～25m/s), and possess high-conversion rate and high reliability; Power range is from 10KW～500KW; Improve wind energy utilization; Reduce the fan starting wind speed less than 3m/s; Reduce impeller diameter with comparing with the power level blower fan, the noise that has produced when the existence of wind gathering cover has reduced blade rotation simultaneously, unit operation is quiet.
Through the wind-collecting type blower fan is studied, utilize wind gathering cover to increase the wind speed that blade facings the wind and distinguishes, not only can improve wind energy utilization, and have the effect that increases wind speed, increase scooter 80%; In low wind speed section, the conversion efficiency of flaring type wind gathering cover is particularly evident.

Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
Fig. 1～shown in Figure 3 comprises lightning conductor 1, gradually expansion type wind gathering cover 2 (wind gathering ring 2-1), impeller 3, turning axle 4, controller 5, blower fan pylon 6, center bearing bracket 7, cabin 8 (efficient permanent magnet low-speed generator 8-1, mechanical brake 8-2), wind gathering cover support 9.
The utility model adopts impeller 3 to be installed on wind gathering cover 2 and facings the wind mouthful and be fixed on the cabin 8; Efficient permanent magnet low-speed generator 8-1 and mechanical brake 8-2 are installed in the cabin 8; Turning axle 4 is installed on blower fan pylon 6 tops, and controller 5 is installed on blower fan pylon 6 bottoms or indoor, is connected with wind gathering cover support 9 on the cabin 8; Wind gathering cover support 9 is in order to fixing gradually expansion type wind gathering cover 2; Gradually expansion type wind gathering cover 2 is installed on the supporting frame 9, and lightning conductor 1 is installed in the top of blower fan apical support frame 9, and the center bearing bracket 7 that stretches out from cabin 8 is installed on the turning axle 4.Said gradually expansion type wind gathering cover 2 is shaped as flaring circular cone loop type, and wind gathering cover 2 exhaust outlets are provided with a ring wind gathering ring 2-1; On the mouth that facings the wind of said gradually expansion type wind gathering cover 2 impeller 3 is housed.
The utility model is because wind gathering cover adopts the ring-like form (principle is seen Fig. 4) of flaring, and young down with the wind, exhaust outlet is big, and exhaust outlet is provided with a ring wind gathering ring, and impeller is contained in the mouth that facings the wind.Wind from wind gathering cover facing the wind mouthful (osculum) get into, exhaust outlet (big mouthful) flows out.The wind gathering cover longitudinal size is less, simultaneously since gradually expansion type wind gathering cover structure than tapering type speedup better effects if to wind speed.So under equal power condition, its blade diameter little (be) with below 1/2nd of power level blower fan, the startup wind speed is low, can breeze wind, the wind energy conversion efficiency can be brought up to more than 40%.The gradually expansion type wind gathering cover also can make blower fan from the motion tracking wind direction, thereby has saved complicated driftage equipment and control system thereof.Owing to the existence of gradually expansion type wind gathering cover, its influence to wind speed field around the blower fan is less, thereby can be installed between the wind power generating set of existing wind field in addition.
Because gradually expansion type wind gathering cover speedup principle, the wind energy utilization of blower fan can bring up to 40%, thus the rotor diameter of blower fan with compare with power Fan and can reduce, half the less than with power level; If under the condition of identical blade dimensions, gradually expansion type wind gathering type wind power generating set output power rises to more than 3 times;
Because gradually expansion type wind gathering cover speedup principle, gradually expansion type wind gathering type wind power generating set starts wind speed and can reduce, and can be applied to low wind speed district.
Because the effect of gradually expansion type wind gathering cover, the minimizing that influences each other in flow field between unit, and the blower fan rotor diameter is less, so with compare with the power level blower fan, the blower fan floor space is little; Wind gathering cover can block the blade that flies out when leaf destruction under the blower fan rotation status, so the Security of gradually expansion type wind gathering type wind power generating set further improves.
