CRYSTALLIZATION TYPE ARTIFICIAL SNOWFALL MECHANISM, ITS ASSEMBLY AND CRYSTALLIZATION TYPE ARTIFICIAL SNOWFALL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a crystallization type artificial snowfall mechanism, its assembly and a crystallization type snowfall device with a not-complicated structure that can generate uniform and high quality crystallization snow in stable manner and can continuously fall a large amount of snow over a wide range.;SOLUTION: A crystallization type artificial snowfall mechanism comprises: a bag-like crystallization type snow collector 31 having an inverse circular truncated cone-shape peripheral surface of which a width becomes narrow from its upper part toward its lower part and having at least a peripheral surface constituted by an air permeation type porous film; a plurality of horizontally tight-contacted circular frames 21 at the inner surface of the peripheral surface of the collector 31; an air supplying passage spaced apart at the outside of the peripheral surface of the collector 31 and having air supplying ports for snowfall air; an air passage 410 passed through the upper part of the collector 31 and having, at the inside of the collector 31, air discharging ports 411 for air permeated through perforated films; and a tension member 51 connected to each of the circular frames 21, straining each of the circular frames 21 and/or vibrating it.;COPYRIGHT: (C)2015,JPO&INPIT
