Abstract

The invention provides an inner cabin ventilation device for a ship. The inner cabin ventilation device comprises a ventilation vertical pipe, a ventilation bent pipe, bolt fixing seats, eye bolts, adjusting seats, fixing nuts, a plug plate and a sealing plate, wherein the ventilation bent pipe is arranged at the top of the ventilation vertical pipe; the bolt fixing seats are arranged on the bottom side of one end of the ventilation bent pipe; two ends of each bolt rotating shaft are fixedly connected with each bolt fixing seat; the eye bolts and the bolt rotating shafts are rotatably connected; each adjusting seat rotationally sleeves the outer side of one corresponding eye bolt; the fixing nuts are arranged at the bottom ends of the eye bolts; the plug plate is arranged at the bottom end of the ventilation bent pipe; and the sealing plate is arranged at the bottom end of the plug plate. The switchover among various working states of the inner cabin ventilation device provided by the invention can be achieved, thereby adjusting the ventilation amount; and the switchover process and the operation process are simple, convenient and rapid.

Description

technical field [0001] The invention relates to the field of ventilation, in particular to an interior cabin ventilation device for ships. Background technique [0002] Ventilation is a building environment control technology that controls the spread and harm of air pollutants and realizes the quality assurance of indoor and outdoor air environments by means of ventilation dilution or ventilation removal. For the purpose of ventilation, it is necessary to use ventilation ducts to transport the airflow at a distance to achieve the purpose of air flow and replacement. Usually, the shape of ventilation ducts is round, square or spiral, etc.; according to the use of ventilation ducts, it is divided into air purification and air conditioning systems. Pipes, air ducts for central air-conditioning systems, air ducts for environmental control systems, air ducts for industrial ventilation systems and air ducts for special occasions. [0003] In the field of ships, the ventilation du...
