Embodiment

[0060] The twin-turbocharged speed-increasing vertical shaft wind power generator of the present embodiment is as figure 1 , figure 2 and image 3 As shown, it consists of two parts: a fixed outer turbine and a rotating inner turbine 2. The fixed outer turbine is a wind gathering deflector 3 evenly distributed on the outer periphery of the inner turbine 2, fixed on the foundation 4, and its function is to gather Wind and diversion. The airflow blowing laterally to the outer turbine area changes the flow direction through the curved surface a and the plane b of the wind gathering deflector 3, plays the role of diversion, boosting and speeding up, and pushes the inner turbine 2 to rotate around the hollow shaft 1. The hollow shaft 1 is fixed on the foundation, and when the outer diameter of the inner turbine 2 is a certain value, the diameter of the hollow shaft 1 changes the width of the inner turbine 1, which also plays a role in boosting and speeding up. The wind-gatheri...

Abstract

The invention discloses a twin-turbocharged speed-increasing vertical-shaft wind power generator, which comprises an outer turbine, an inner turbine and a hollow shaft. An annular guide rail is installed on the outer periphery of the shaft, and the inner turbine is installed on the annular guide rail; the wind gathering deflector is evenly distributed on the outer periphery of the inner turbine, and a generator is installed on the hollow shaft, and a transmission device is connected between the generator and the inner turbine. The invention has the advantages of large wind-receiving area, large effective wind-receiving angle, high utilization rate of wind energy and the like.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a twin-turbocharged speed-increasing vertical shaft wind power generator. Background technique [0002] New energy power generation, especially wind power generation, is generally highly valued by the energy strategies of countries all over the world. Energy supply and environmental protection are the basic conditions for sustainable economic development. Wind energy is a clean, environmentally friendly, economical, and practical renewable energy source, which is inexhaustible and inexhaustible, and has attracted more and more attention from people. The United Nations Environment Program reported in 2010: "In the past 20 years, the world's energy consumption has increased by 50%, and from now to 2020, global energy consumption will increase by 50% to 100% compared with the present, resulting in greenhouse gas emissions. It will increase by 45% to 90%, which will bring catastrop...
