Abstract

The invention aims to provide a turnover water-inflow-preventing ventilator device which is compact in structure, good in ventilation quality and capable of meeting the ventilation requirement duringnormal operation, automatically closes for water prevention during turnover and automatically keeping ventilation after turnover is recovered. The turnover water-inflow-preventing ventilator device comprises an air duct and a protection assembly, the bottom of the air duct communicates with a cabin, the protection assembly is arranged at one end of the air duct, a check valve is arranged between the air duct and the protection assembly, and a gravity valve disc matched with the check valve is hinged to the end, close to the protection assembly, of the check valve; a sealing washer is arrangedbetween the gravity valve disc and the check valve, an opening is formed in the bottom of the protection assembly, and the cross section of the opening is parallel to the horizontal plane. The invention is applied to the technical field of ventilator waterproof structures.

Description

technical field [0001] The invention relates to the technical field of a ventilator waterproof structure, in particular to an overturning anti-water entry ventilator device. Background technique [0002] For special ships with self-righting requirements, they can be self-righting after capsizing, that is, in special circumstances such as ship overturning, it is necessary to maintain the safety and normal operation of the ship. The ventilator commonly used on board, although the opening is only provided with a weathertight cover or a manual closing device, it needs to be closed manually. In the normal open working state, when the ventilator turns over with the ship, it cannot be automatically closed and cannot block the external sea water Enter the relevant ventilation cabin from the fan cylinder. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a compact structure, ...
