Efficient double-wind wheel differential self-balancing wind power generator

Abstract

The invention discloses an efficient double-wind wheel differential self-balancing wind power generator, belonging to the field of wind power generators, and aims to solve the problems in rotation speed balance and coordination efficiency of two wind wheels and to implement rotation speed balance of the double wind wheels and improve efficiency by adopting a differential reduction gear box of the automobile rear axle. The speed of the wind machine is increased by reversely applying the reduction gear box of the automobile rear axle. As the diameter of the front wind wheel is small and the mounting attack angle of the wind blades is big while the diameter of the rear wind wheel is large and the mounting attack angle of the wind blades is small, organic combination between the low-speed wind machine and the high-speed wind machine is realized (the functions of the low-speed large-torque wind machine and high-speed small-torque wind machine are obtained at the same time). As the diameter of an impeller of the rear wind wheel is large and the mounting attack angle of the wind blades is small, the total windward area of the rear impeller is larger than the total windward area of the wind blades of the front wind wheel so as to realize automatic wind search of the wind machine.

Description

Technical field: [0001] The invention belongs to the field of wind power generators, in particular to a high-efficiency double wind wheel differential self-balancing wind power generator. technical background: [0002] The principle of wind power generation is to use wind pills to drive the wind rotor blades to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. According to the current wind wheel technology, three-blade horizontal axis wind turbines are generally used, and most of them use a single wind wheel. If high efficiency is obtained, a large-diameter wind wheel is required, which makes manufacturing difficult and expensive. And the balance problem of three blades is not easy to solve. [0003] By retrieving information and referring to existing patents: "horizontal orthogonal differential speed type co-rotating double-sided impeller wind power generator set", "a low-cost kilowatt-class wind pow...
