Vertical-axis wind turbine

Abstract

The invention discloses a vertical-axis wind turbine which comprises blades, a spindle and a main motor base. The blades are fixed to the spindle through a connecting support. The connecting support comprises a first connecting body and a second connecting body which are vertically and fixedly connected; spindle holes communicating with each other are formed in the first connecting body and the second connecting body; connecting rods are arranged on the right side of the first connecting body and the left side of the second connecting body; first threaded holes are formed in the left side of the first connecting body and the right side of the second connecting body; and second threaded holes are formed in the top ends of the connecting rods. The two ends of the blades are fixedly connected through the first threaded holes and the second threaded holes in the connecting support through bolts. The spindle penetrates through the spindle holes to be fixedly connected with the connecting support. The spindle is connected with a drive shaft on the main motor base through a coupler. The vertical-axis wind turbine is stable in structure and long in service life. Protection coatings sprayed on the blades have excellent weather resistance, are resistant to abrasion, corrosion and ageing and high in self-cleaning capacity, and can greatly prolong the service life of the blades.

Description

technical field

[0001] The invention belongs to the field of wind power generation, in particular to a vertical axis wind power generator. Background technique

[0002] At present, the survey found that most of the structures of vertical axis generator sets sold on the market are fan blades connected to the upper and lower flanges of the generator through connecting rods. On the upper and lower flanges, the service life of the generator set is reduced. Another structure is to wrap the generator in the welded frame, and the deep groove ball bearings at both ends play a supporting role. The whole weight is shared by the frame. However, due to the selection of Deep groove ball bearings, while the generator set is installed on a vertical shaft, so during operation, the axial force on the bearing is much greater than the radial force, which reduces the service life of the bearing. At the same time, the outer rotor motor needs to be used during installation. As far as the fan mou...
