Muffling detachable ventilator for ship

Abstract

The invention discloses a ship noise reduction detachable ventilator, and relates to the technical field of ship ventilators, the ship noise reduction detachable ventilator comprises a fixed cylinder, an air cap cylinder arranged on the top of the fixed cylinder and an air cap cover arranged on the top of the air cap cylinder, the bottom of the air cap cylinder is connected with a vertical air inlet pipe, the top of the air cap cover is provided with a ventilation pipe, and the upper part of the fixed cylinder is internally provided with a fan; a silencing assembly is arranged in the fixing cylinder, and a ventilation mechanism is arranged on the outer wall of the stabilizing cylinder. A plugging mechanism for closing the air inlet pipe is arranged in the middle of each ventilation opening; through cooperation of the sealing cover, the plugging mechanism and the ventilation mechanism, the ship can have two different ventilation operation modes during ventilation operation, different ventilation operations can be switched conveniently according to different weather conditions, the protection effect of the ship during ventilation operation is effectively improved, double sealing operation can be conducted, and the ventilation effect of the ship is improved. And through the arrangement of the silencing assembly and the silencing cotton, the quietness of the device during use is effectively improved.

Description

technical field [0001] The invention relates to the technical field of ventilators for ships, in particular to a sound-absorbing detachable ventilator for ships. Background technique [0002] Ship is the general term for all kinds of ships. In the era of rapid development of science and technology, people's requirements for the internal environment of ships are also gradually increasing. Generally speaking, in order to ensure the circulation of air, it is necessary to install an appropriate number of ventilators on ships. Traditional ship ventilators can basically meet people's needs; [0003] However, there are still certain problems in the use of the existing ventilators for ships. When running into bad weather at sea, the ventilators on the ships need to be closed, causing the ventilators to fail to perform normal ventilation operations. The ventilator of this structure has poor ventilation effect; and in the event of bad gas gathering weather, the existing ventilator ca...

Problems solved by technology

[0003] However, there are still certain problems in the use of the existing ventilators for ships. When running into bad weather at sea, the ventilators on the ships need to be closed, causing the ventilators to fail to perform normal ventilation operations. The ventilator of this structure has poor ventilation effect; and in the event of bad gas gathering weather, the existing ventilator can only perform single-layer sealing operation, resulting in poor sealing performance of the ventilator when it is completely closed , and most of the ship ventilators currently on the market are equipped with power fans inside in order to improve the ventilation effect, but the power fans will generate certain vibrations when they are working, and then transmit them to the ventilators and generate relatively loud noises. Thus affecting the normal rest of the ship's staff; therefore, it is necessary to solve the above problems
