Twin-turbo supercharging and speed-increasing vertical shaft wind driven generator

Abstract

The invention discloses a twin-turbo supercharging and speed-increasing vertical shaft wind driven generator which comprises an outer turbo, an inner turbo and a hollow shaft. The outer turbo comprises wind concentrating guide plates fixedly connected with a foundation. The hollow shaft is fixedly connected with the foundation. Annular guide rails are mounted on the periphery of the hollow shaft. The inner turbo is mounted on the annular guide rails. The wind concentrating guide plates are uniformly distributed on the periphery of the inner turbo. A generator is mounted on the hollow shaft. A transmission device is connected between the generator and the inner turbo. The twin-turbo supercharging and speed-increasing vertical shaft wind driven generator has the advantages of large windward area, large effective windward angle, high wind energy utilization rate 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...
