Overhead wind power generator

Abstract

The invention relate to a wind power generator, in particular to a wind power generator and device combination equipment driven by the same. The overhead wind power generator comprises a balloon and a generating device, wherein the generating device is connected with the balloon and a draught fan; the draught fan comprises a draught fan support and two rotors, wherein the two rotors are bilaterally symmetrically arranged in the draught fan support; flexible blades are arranged on the two rotors; and the flexible blades on one rotor are arranged oppositely to the flexible blades on the other rotor. Two rotors for the draught fan are adopted to drive the overhead wind power generating device to generate power, thus the high efficiency of the system is ensured. Compared with the traditional known wind power generator which adopts a transmitting belt or chain to transmit power to the ground to drive the wind power generator to generate power, the overhead wind power generator has greatly simplified structure.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a combination device of a wind power generator and a device driven by it. Background technique [0002] Traditional power development using coal, oil, and natural gas as raw materials or resources has caused a lot of environmental burdens, such as environmental pollution, acid rain, abnormal weather, oil spills, and so on. Wind energy, as a renewable energy source, is characterized by its remarkable environmental friendliness and abundant production capacity. Therefore, the development and utilization of wind energy and the development of wind power are one of the effective ways to reduce greenhouse gas emissions, protect the ecological environment, and solve the current severe energy situation. [0003] In the past 30 years, near-ground wind power generation has rapidly developed from experimental research to a mature technology, and the cost of power generation has been greatly reduced...

Problems solved by technology

This device can utilize high-altitude wind energy, but its system is very complicated, especially controlling the attitude of the invisible airbag at high altitude

In addition, the recovery stage of the device needs to consume some energy, which affects the efficiency of the device

The Chinese patent announced on October 29, 2008, the publication number is CN201141339, which discloses a high-altitude wind energy utilization device, the upper part of the rotating wind wheel is connected with a traction kite through the kite traction line, and the upper drive wheel integrated with the wind wheel is passed through the traction drive belt, The chain is connected to the lower transmission wheel on the ground to drive the generator, etc. Although the structure of this device is relatively simple, it will affect the efficiency when the power is transmitted from high altitude to the ground through multi-stage

Although the device has the advantages of low starting wind speed and relatively simple structure, a single turbine rotor will generate a reverse torque under the action of wind force, which cannot be balanced, which will cause the instability of the power generation system
