Background technique

Whether it is a horizontal axis or a vertical axis, whether it is a large machine or a small machine, the power generation efficiency of wind turbines is closely related to the speed. The speed of wind turbines is generally only a few to several hundred revolutions, so in order to increase the speed of the mainframe, a gear speed increase device is used.

The present invention takes a disc motor as an example to illustrate, and the two wind turbines respectively drive the rotor armature disk and the excitation magnet disk to rotate in opposite directions.

The first rotary rod is connected with the generator casing, and the excitation magnet is fixed on the generator casing. Through the different installation arrangements of the blades, the rotation directions of the two wind turbines are opposite, so that the first wind turbine is just opposite to the second wind turbine. The sum of the rotational speeds of the two, the first wind turbine drives the generator housing to rotate, that is, drives the excitation magnet to rotate, and the second wind turbine drives the rotor armature disc to rotate, increasing the rotational speeds of the two wind generators.

Further, the rotor of the generator is an armature disc, and the stator is a field magnet.

Further, the armature disc is connected to the collector ring provided at the end of the fixing rod through wires.

Further, the rotor armature disc is connected to the second rotary rod and arranged perpendicular to each other.

Further, the excitation magnets on the upper and lower end covers of the generator are fixed on the upper and lower end covers of the generator, and the magnets are separated from the armature disc by a set distance.

Further, the first rotary rod is fixed to the outside of the second rotary rod through a bearing.

Further, the number of blades of the first wind turbine and the second wind turbine is the same.

Further, the top of the second rotary rod passes through the top of the first rotary rod.

The specific steps of the manufacturing method of the double-speed vertical axis wind power generator are as follows:

1) A plurality of blades are arranged symmetrically on the periphery of the lower half of the second rotary rod of the second wind turbine;

2) Fix the bottom of the fixed rod, fix the collector ring at the top, and put it in the second rotary rod of the second wind turbine;

6) Fix the casing of the generator so that the position of the rotor is set between the upper and lower magnets.

Further, the steps 1) and 3) can be performed simultaneously, or the order of the steps 1) and 3) can be changed.

The working principle of the present invention is:

According to the basic formula of the generator, the formula of power P can be derived:

m---Number of phases. electromotive force and current They are:

Among them, k _d is the winding factor, k _p is the pitch factor, N _c is the number of coil turns per phase, f is the rated frequency of the disc motor,

p is the number of pole pairs of the motor, n is the speed of the motor, Bv is the maximum value of the air gap magnetic flux, and _Sc is the area of the coil.

Among them, K is the structural coefficient of the motor. It can be seen from the above formula that the output power of the generator is proportional to the square of the generator speed.

Two wind turbines respectively drive the rotor armature disk and the excitation magnet disk to rotate relative to each other. Since the rotation directions of the two wind turbines are facing each other, the relative rotational speed is doubled, so the speed at which the generator cuts the magnetic field line is increased, and the power generation of the generator increases with the With the increase of the relative speed, the power generation efficiency is improved at the same time.

The beneficial effects of the present invention are:

1) Through the two wind turbines arranged up and down, one wind turbine drives the armature disk to rotate, and the other wind turbine drives the magnet to rotate in the other direction, making full use of the relative movement between the excitation magnet and the armature disk to improve the generator Rotating speed.

2) The structure of the whole generator is simple, no synchronous reverse mechanism is needed, the torque is balanced, the rotating speed of the generator is increased, and the power generation efficiency is further improved.
