Subway tunnel wind power generating device with double-wind wheel wind energy capture and spring energy storage structure

Abstract

The invention discloses subway tunnel wind power generating device with a double-wind wheel wind energy capture and spring energy storage structure. The device comprises double-wind wheel wind turbines, a speed reducing gearbox, a spring energy storage box, a mechanical energy sustained release device, a permanent magnet generator, a direct current converter and a direct current bus which are connected in series in a staggered manner. Double-wind wheel wind energy capture is realized through the double-wind wheel wind turbines which are connected in series in the staggered manner, and the windenergy utilization rate and the output torque are increased; high rotating speed of the wind turbines is converted into low rotating speed high torque output through the speed reducing gearbox, whichis beneficial for energy storage of a spring; the captured wind energy is stored as mechanical energy through the spring energy storage box; the conversion from the mechanical energy to electric energy is realized by the permanent magnet generator; and alternating current is converted into direct current and the direct current is output to the direct current bus through the direct current converter. The subway tunnel wind power generating device with the double-wind wheel wind energy capture and spring energy storage structure can realize the functions of tunnel wind energy capturing, mechanical energy storage and power generating, has the advantages of safety, high wind energy utilization rate and the like, and fills the technological gap of mechanical energy storage and renewable powergeneration of tunnel wind energy.
