Description

Device for rapidly separating wind flow Technical Field The utility model relates to the technical field of coal mine operation protection equipment, in particular to a device for rapidly isolating wind flow. Background In the operation of coal mine tunnel, in order to prevent the diffusion of harmful gas caused by fire, gas explosion and other accidents, a wind flow partition structure needs to be quickly constructed, and the traditional partition device mainly adopts a pneumatic partition door which is driven by compressed air to close a door body. However, the fire disaster needs to be rapidly completed in the early stage, the traditional device cannot meet the requirements due to mechanical transmission delay or manual operation lag, and the pneumatic partition door of the traditional device is of a one-way opening structure, trapped personnel cannot rapidly break through from the partition side, and self-rescue opportunity may be delayed. Therefore, to above-mentioned problem, the present provides a cut off wind flow device rapidly, adopts electromagnetic structure like magnetic pole mutually exclusive principle, realizes automatic upset closure, adopts two-sided openable structure simultaneously, and stranded personnel only need light handle can push away magnetism and inhale the connecting plate, shortens unilateral escape time, and magnetic force automatic re-setting after the closure, ensures the separation effect, in colliery conflagration emergency scene, satisfies the demand of cutting off fast and urgent escape simultaneously, is showing and is promoting the operation security. Disclosure of utility model In order to overcome the in-process that daily use traditional cuts off the work of windage device, there is traditional device because of mechanical transmission delay or manual operation lag can't satisfy the requirement, and traditional device's pneumatic partition door is one-way open structure, and stranded personnel can't break through from cutting off the side fast, probably delay the problem of saving oneself the opportunity.
