Description
Technical Field
The utility model relates to a power generation facility's technical field, concretely relates to aerogenerator.
Background
A vertical axis wind turbine refers to a wind turbine in which the axis of rotation of the rotor is perpendicular to the ground or the direction of the wind flow. The vertical axis wind driven generator does not need to face the wind when the wind direction changes, and the vertical axis wind driven generator is a great advantage compared with a horizontal axis wind driven generator, so that the structural design is simplified, and the gyroscopic force of a wind wheel when facing the wind is reduced, and the vertical axis wind driven generator has a very good development prospect.
The traditional vertical axis wind driven generator adopts an inner rotor generator, and because the wind wheel part (blades, a transmission shaft and a connecting wing) of the vertical axis wind driven generator is heavier, a bearing of a motor shaft is subjected to larger axial load, so that the rotating torque of the motor is increased, the blades cannot be started at lower wind speed, and the generating efficiency of the vertical axis wind driven generator is reduced.
The above problems are urgently needed to be solved.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of background art, the utility model provides a aerogenerator, the technical problem of solution is torque when how effectively reducing the generator electricity generation, improves the generating effect.
For solving the technical problem, the utility model provides a following technical scheme:
the wind driven generator comprises a supporting seat, a disc type generator and a rotating shaft, wherein the supporting seat, the disc type generator and the rotating shaft are arranged from bottom to top, the supporting seat is fixedly connected with a stator of the disc type generator, the rotating shaft is fixedly connected with a rotor of the disc type generator, and the rotating shaft is fixedly connected with a plurality of fan blades.

fig. 2 is a sectional view of the connection structure of the rotating shaft and the disc generator of the present invention.
Detailed Description
As shown in the figures, the wind power generator in this embodiment includes a supporting seat 1, a disc generator 2 and a rotating shaft 3 arranged from bottom to top, wherein the supporting seat 1 is fixedly connected to a stator 21 of the disc generator 2, the rotating shaft 3 is fixedly connected to a rotor 22 of the disc generator 2, and the rotating shaft 3 is fixedly connected to a plurality of blades 4.
In this embodiment, the fan blade 4 is fixedly connected to the rotating shaft 3 in the following manner: the rotating shaft 3 is provided with a connecting rod 5 vertical to the rotating shaft, and the fan blade 4 is connected with the connecting rod 5.
In the embodiment, the shape of the fan blade is spiral H-shaped in the vertical direction, so that the wind energy is utilized better, and the power generation efficiency is improved.
The utility model has the advantages of simple structure, the fan blade drives the pivot and then directly drives rotor 22 of disk generator and rotates for its stator 21 to the generating efficiency is higher. Furthermore, the utility model discloses a disc motor starting torque light, the rotational speed is slow, small, and the load acts on the shell of motor, and the pressure that pivot 3 received reduces greatly, when promoting wind power generation efficiency, has prolonged the life of pivot.
The working principle of the embodiment is as follows: the supporting seat 1 of the wind driven generator is fixedly arranged on the ground, the stator of the disc type generator 2 is fixedly connected to the supporting seat 1, when the wind blows the fan blades 4 to rotate, the fan blades 4 drive the rotating shaft 3 directly connected with the connecting rods 5 to rotate through the connecting rods 5 directly connected with the fan blades 4, and the rotating shaft 3 is fixedly connected to the rotor 22 of the disc type generator 2, so that the rotor of the disc type generator 2 is synchronously driven by the rotating shaft 3 to rotate, and the rotor 22 of the disc type generator 2 rotates relative to the stator 21 of the disc type generator 2, and a power generation effect is. In the whole process, the fan blades drive the rotating shaft 3 to directly drive the rotor 22 of the disc type generator 2 to rotate relative to the stator 21, so that the torque generated by the disc type generator 2 is small, the wind driven generator can generate more electricity under the same wind power compared with the traditional vertical axis wind driven generator, the power generation effect is effectively improved, and the power generation cost is reduced.
