Vertical-axis wind driven generator

Abstract

The invention provides a vertical-axis wind driven generator comprising a chassis, a strut, a motor, a main shaft, a plurality of supporting wings, resistance blades and lift force blades, wherein the motor is fixed on the strut; the main shaft is axially connected with the motor; the supporting wings, the resistance blades and the lift force blades are horizontally installed on the main shaft; the supporting wings are distributed around the main shaft at equal distance; the resistance blades are fixedly installed on the main shaft; the lift force blades are installed on the outer end parts of the supporting wings; the longitudinal section of each lift force blade is vertical to the horizontal plane; and the supporting wings are made of carbon fiber material. The vertical-axis wind driven generator adopts the design of complementary lift force and resistance, the supporting wings are made of the carbon fiber material with the advantages of high strength, low density and the like, and the invention provides a vertical-axis wind driven generator which has the advantages of light weight, low working noise, high reliability and high working efficiency.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a vertical axis wind power generator adopting a lift-drag complementary design. Background technique [0002] With the improvement of people's consumption level, the demand for energy is increasing, and the resulting lack of energy has attracted attention from various fields, and they have devoted themselves to improving energy utilization and developing various new energy sources, especially green Energy has become a goal that people are constantly pursuing, such as hydropower, solar energy, and wind power. Wind energy is one of the most promising, most practical, fastest-growing and relatively mature renewable energy sources, but its application as power generation energy accounts for only a small part. Difficult to install and difficult to maintain. Vertical axis wind turbines are known as a new generation of wind turbines. Compared with traditional horizontal axis wind turbines, th...

Wind energy is one of the most promising, most practical, fastest-growing and relatively mature renewable energy sources, but its application as power generation energy accounts for only a small part. Difficult to install and difficult to maintain

Vertical axis wind turbines are known as a new generation of wind turbines. Compared with traditional horizontal axis wind turbines, they have the advantages of low cost and high efficiency, and are more suitable for our living environment. Vertical axis wind turbines are divided into resistance Type and lift type, the resistance type generator uses resistance type blades, good starting performance, but the power generation efficiency is relatively low, the lift type generator uses lift type blades, high power generation efficiency, but relatively poor starting performance
