Triangular soft-wing vertical axis offset wind turbine with headwind output

Abstract

The invention discloses a triangular soft wing type vertical axis offset distance wind turbine with headwind force. The triangular soft wing type vertical axis offset distance wind turbine comprises a vertical axis, transverse beams, ventilating nets and one light soft blade, wherein the transverse beams are symmetrically fixed on the vertical axis; two ventilating nets and the light soft blade which are in a right triangle shape are arranged below the outer end of each transverse beam; the light soft blade and the two ventilating nets share one inclined side and extend outside the outer lower side; the two ventilating nets are perpendicular to each other, and one ventilating net is vertically arranged; and the light soft blade is arranged between the two ventilating nets. When wind comes from any direction, the light soft blade in following wind direction is shielded on the vertically arranged ventilating net and has a large wind catching surface, so that the vertical axis is driven to rotate; when being rotated to the headwind direction, the blade is blocked on the obliquely arranged ventilating net, the vertical axis is continuously driven to rotate, the blade is gradually separated from the obliquely arranged ventilating net to wave along with wind, and the wind resistance is avoided; and moreover, all the materials are in light design, and the triangular soft wing type vertical axis offset distance wind turbine is low in starting wind speed, high in solidity and torque, low in cost, rapid in state change and high in practicality.

Description

technical field [0001] The invention relates to an offset vertical axis wind turbine, in particular to a triangular soft-wing type vertical axis offset wind turbine with headwind output. Background technique [0002] Today, non-renewable energy sources such as oil, coal, and natural gas are facing depletion of reserves, rising prices, and even serious pollution of the earth's environment. The danger of nuclear fission power generation is high, and nuclear waste pollutes the environment and is difficult to deal with; it is not feasible to use nuclear fusion energy to generate electricity. However, solar energy and wind energy are renewable energy sources that do not pollute the environment. Therefore, all countries are vigorously developing clean and renewable energy represented by wind energy and solar energy. [0003] In the current field of wind energy utilization, most of the existing wind turbines with large installed capacity are mostly in standby or shutdown state, a...
