JPH03286190A - Wind power generating device for magnetic levitation vehicle - Google Patents

Abstract

PURPOSE:To efficiently supply power except for propulsion consumed in a vehicle by providing a wind passage having a sound absorbing means with an uneven cross section inside a structure of a car body of a magnetic levitation vehicle, by arranging a turbine in the wind passage and by arranging a stationary blades on the upper stream side and/or the lower stream side of the turbine. CONSTITUTION:The air sucked from an opening 10 provided at the tip end lower part of a cowling of a first vehicle 1 is made to pass a wind passage 11 of a required length and then, exhausted from an exhaust port 12 opened at a ceiling part of the vehicle 1. A turbine 13 in the wind passage 11 is arranged at such a required position that is selected so that the air sucked into the passage is appropriately compressed and then, made to work, and a driving force of the shaft of the turbine 13 is transmitted by a transmission mechanism to a generator 14 provided outside the wind passage 11. Stationary blades 22 and 24 are arranged at front and rear positions of the turbine 13, and either or both of pitch of the stationary blades 22 and 24 are controlled according to speed of the vehicle 1 or wind speed introduced into the wind passage so as to optimize the attack angle of the turbine 13 all the time. A sound absorbing means 30 is provided on all the inner walls of a wind passage arranged in the vehicle, for instance, the wind passage 11.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an on-vehicle auxiliary power supply device for supplying electrical energy consumed inside a vehicle other than the propulsion of a high-speed railway such as a maglev railway. The ram air obtained by propulsion is used as a wind power generation device to drive an axial flow turbine whose stationary blade q pitch can be changed.A wind path with a non-uniform cross section with sound absorption means is installed inside the car body structure, and the air The present invention relates to a wind power generation device for a magnetic levitation vehicle, which increases the efficiency of intake and exhaust of air into the wind tract and reduces noise outside the vehicle.

Conventional technology Currently, the development of magnetic levitation railways is underway as a means of mass transportation for the future, providing high speed, safety, and non-pollution. The mechanism works with the superconducting magnets above to levitate the vehicle and propel it without contacting the orbit.

Due to this propulsion principle, it is possible to achieve a running speed as high as 500 km/h. Therefore, it is difficult to supply electrical energy for lighting, air conditioning, etc. consumed inside a vehicle by using contact methods such as Pandagraph, which is a typical conventional method, because it is expected to be difficult due to the high speed mentioned above. A contact type method is desired.
