Abstract

The invention relates to the technical field of marine machine ventilation systems, in particular to a side opening type ventilation device with a weather tight mechanism.The side opening type ventilation device is provided with a ventilator with a top opening and an oval-shaped hood covering the top of the ventilator.A lead screw is installed in the middle of the ventilator.A hand wheel is installed at one end of the lead screw.Two connecting rods and two cover plates are installed in the middle of the lead screw.The other end of each connecting rod is hinged to the middle of the corresponding cover plate.The hand wheel drives the lead screw to rotate and drives each connecting rod to drive the corresponding cover plate to open the top opening of the ventilator or close the top opening of the ventilator.The ventilation device is novel in structure, remarkable in ventilation effect and low in using cost.

Description

technical field [0001] The invention relates to the technical field of marine mechanical ventilation systems, in particular to a side-opening ventilation device with a weathertight mechanism. Background technique [0002] The ship's ventilation system is a piping system that uses machinery or relies on natural air circulation to ventilate the ship's cabins. The ship's ventilation system is divided into two types: mechanical ventilation and natural ventilation. Mechanical ventilation is mainly composed of axial fans, ventilation ducts, and air distributors. Natural ventilation is mainly composed of openings (doors, windows, hatches, ventilation funnels) of the ship itself and natural ventilation ducts. [0003] At present, the ship ventilation system mainly adopts the mechanical ventilation method, and a drain butterfly valve is usually installed at the bottom of the ventilator, which greatly increases the user's use cost. Contents of the invention [0004] The technical ...
