Abstract

An integrated multifunctional device is provided for grid-connected/off-grid wind-turbine generation and electric drive, with easy start. The shaft of motor is hollow cylindrical shaft having a diameter several times of or tens of times of that of the conventional motor shaft. Huge wind wheel is directly installed in the driving shaft of the motor. Booster engine is installed within the body of the motor, so as to shorten the transmission distance. Ratchet wheel mechanism is disposed between the wheel spider of generator wind wheel and the driving shaft. When the wind wheel is failed, the generator can support the load-free grid connection of electromotor until the rotation speed of wind wheel is enough for power generation. The most important is that the utility model overcomes the power oscillation due to wind change. The generator shafts different in diameter can be sheathed together and a group of wind wheel and motor rotor can be provided homocentrically in each shaft different in diameter. Permanent magnet pole combines excitation pole to suit for the operation of herdsman, fishermen and army in off-grid power net or small power net.

Description

The starting of one multifunction simple is incorporated into the power networks from the dual-purpose machine of net wind power generation electric

Affiliated technical field

The utility model relates to the starting of a kind of one multifunction simple and is incorporated into the power networks from the dual-purpose machine of net wind power generation electric, and a kind of unit need not add auxiliary equipment connects installation with electrical network after, the dual-purpose machine that just closes a main switch and can be electronic or to generate electricity.

Background technology

At present, known wind-driven generator will assemble complicated acceleration equipment outside generator, the cost of wind-driven generator is improved, also increased the complexity of installing, the wind wheel wheel hub and the generator drive axle of wind-driven generator are fixed together simultaneously, wind direction sudden change or moment are during stop, wind-driven generator has become the motor with huge wind wheel load, consume a large amount of electric power of electrical network suddenly, cause the electrical network vibration, in addition, the axle of present wind-driven generator is a solid shafting, the thin intensity of axle is low, can not bear the moment of torsion of huge wind wheel separately.

Summary of the invention

In order to overcome the deficiency that existing generator and motor exist, the utility model provides a kind of one multifunction simple starting to be incorporated into the power networks from the dual-purpose machine of net wind power generation electric, this machine has not only overcome the deficiency of existing generator, and the cost of wind power generation is reduced greatly, and fail safe improves greatly;

The technical scheme that its technical problem that solves the utility model adopts is: 1, the axle of motor is designed to the hollow cylinder profile shaft, the diameter of axle can be several times or several ten times of original motor shaft diameter, huge wind wheel can be directly installed on the motor transmission shaft, the weight and the manufacturing cost of motor have been reduced simultaneously greatly, 2 booster engines are installed in the body of motor, have shortened the transmission distance, have reduced the transmission energy loss, reduced manufacturing cost, the installation and maintenance of being more convenient for; 3, between generator wind wheel wheel hub and power transmission shaft, assemble ratchet mechanism, generator not can be used as the zero load starting of motor yet and is incorporated into the power networks when wind wheel did not change, wait for that wind wheel drives generator for electricity generation when reaching the generating rotating speed again, the most important thing is, overcome the vibration that the complicated variation of wind-force causes to electrical network; 4, the axle of generator is the hollow cylinder profile shaft, the axle of different-diameter can be sleeved on together, on each axle concentric, different-diameter, all can assemble one group of wind wheel and rotor respectively, promptly in a motor multistage wind wheel and multipolar dynamo rotor can be arranged, form the magical function of a plurality of sub-motors whiles, concentric operation in a long motor body; 5, the utility model motor bearings adopts radial-axial magnetic suspension sliding bearing, can improve electric efficiency.6, the utility model multipolar dynamo adopts permanent magnetism magnetic pole to load in mixture with excitation pole to be in the same place, and the environment that makes it to adapt to any there is electric power or not all can generate electricity, work, and is more suitable for herdsman, fisherman, army and is independently finishing the work in net or minor scale power net.For example certain individual (such as on a ship) has two such motors, and one can stand in the generating of ship top, and one can be used as motor rotating screw slurry and promotes the hull operation.

The beneficial effects of the utility model are to have simplified the program of generating greatly, for generation of electricity by new energy, wind energy, water energy, ocean current, tidal power generation provide the motor that is suitable for.
