Abstract

The invention discloses an air-lock structure for civil air defense engineering safety. The air-lock structure for civil air defense engineering safety comprises a passage body and an exhaust mechanism arranged at a top plate of the passage body and used for pumping and exhausting poison gas; and the exhaust mechanism comprises a gas suction mechanism and a lifting mechanism which is connected with the gas suction mechanism and drives the gas suction mechanism to ascend and descend. According to the gas defense passage structure, by arranging the lifting mechanism comprising connecting rods, the two-way lead screw, moving blocks, a worm wheel, a worm, a telescopic rod, a full-width gear, a first half-width gear, a second half-width gear, a second transmission shaft and a reduction gearbox, periodic up-down movement of the gas suction mechanism is achieved, the quantity of driving mechanisms and control mechanisms is decreased, periodic pumping and exhausting of poison gas at different heights in the passage body are achieved, and a good poison gas pumping and exhausting effect is achieved.

Description

technical field [0001] The invention relates to the field of anti-virus equipment for civil defense passages, in particular to an anti-virus passage structure for the safety of civil defense projects. Background technique [0002] Better exhaust effect is required in civil air defense passages. In the case of fire or other poisonous gas, it is necessary to exhaust the poisonous gas. The traditional exhaust device has a fixed structure and a fixed position. Different poisonous gases have different densities and suspension heights. Different, the traditional exhaust device can't exhaust the poisonous gas at different suspension heights well, and the extraction efficiency is not high. [0003] The application provides an anti-virus channel structure for civil air defense engineering safety. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned in the above-mentioned background technology, the present invention provides an anti-virus channel ...
