Gyro rotating vertical shaft type wind driven generator

Abstract

The invention provides a gyro rotating vertical shaft type wind driven generator, which comprises a supporting column fixedly arranged on the ground; a base plate is fixed to the top of the supportingcolumn; a generator body is fixedly installed on the base plate; a rotating shaft composed of a rotor connecting section, a lower section, a middle section and an upper section extends out of the topof the generator body; the rotor connection section is connected with a generator rotor; a rotating shaft shell is arranged on the periphery of the surface of the lower section; the lower end of therotating shaft shell is fixed to a generator shell; upper and lower tapered roller bearings are fixedly embedded in the rotating shaft shell; and center holes of the upper and lower tapered roller bearings are fixedly connected to the surface of the lower section in a sleeved mode; a circular gyro rotary cake that gradually thins from the center to the edge is fixed at the middle section; the periphery of the gyro rotary cake is connected with four cross-shaped orthogonal connecting pieces; each connecting piece is connected with a scallop-shaped blade with the thickness gradually reduced fromthe fan center to the fan edge; and the upper section is connected with a top cover. According to the gyro rotating vertical shaft type wind driven generator provided by the invention, the frictionalresistance of a gyro principle to the rotating shaft is small, so that the generator rotor can obtain faster and more continuous effective torque, and more power is generated.

Description

Technical field[0001]The invention relates to the technical field of wind power generation, in particular to a gyro-rotating vertical axis wind power generator.Background technique[0002]A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. The inventors of the present invention have discovered through research that the current prevailing slender blade horizontal axis wind turbines on the market require a higher level of wind power, such as level four or more, to start, and the speed is slower at 10-20r / min. Only 50~150r / min, the frictional resistance is large, so that the effective torque obtained by the generator rotor is not large, and the efficiency of the wind generator is not high. All kinds of vertical axis wind turbines (ie vertical axis wind turbines) increase the torque by increasing the blades. As the dead weight of the blades increases, the friction and air resistance inc...

Problems solved by technology

[0003] In view of the large frictional resistance of the rotating shaft connected to the generator rotor when the existing wind power generator generates electricity, the effective torque obtained by the generator rotor is not large, and the generator rotor speed is naturally not fast, and the power generation is not much , which in turn leads to the technical problem that the efficiency of the wind power generator is not high. The present invention provides a gyro-rotating vertical axis wind power generator
