Exhausting wave-resistant water stop device

Abstract

The invention provides an exhausting wave-resistant water stop device. The wave-resistant and water stop functions on an exhausting pipeline can be achieved and water can be prevented from entering equipment from the exhausting pipeline. The exhausting wave-resistant water stop device comprises an exhaust elbow, a wave-resistant shell, a hinge, a sliding mechanism, a water baffle and a floater, and peripheral equipment is an exhaust pipe. A mounting hole used for being connected with an exhaust port of the exhaust pipe is formed in the right side surface of a protective cover, an exhaust hole is formed in the arc surface, and one end of the exhaust hole is connected with the water baffle through the hinge. The floater and a guiding mechanism are located in the protective cover, and the end face of one side of the floater is tightly attached to the end face A of the protective cover. When water enters the protective cover from an opening in the bottom surface of the protective cover, the floater floats along the sliding mechanism so as to block off the exhaust port.

Description

technical field [0001] The invention relates to a water stop device, in particular to an exhaust wave anti-water stop device. Background technique [0002] In order to safeguard national marine interests and explore marine resources, it is imperative to develop marine high-tech equipment. From the analysis of the development situation at home and abroad in recent years, the marine development of various countries in the world has gradually advanced to the far sea and deep sea areas, and developed a kind of underwater detection capability at a certain depth, long sailing time, and used to identify detected targets. Underwater vehicles are a very important aspect to be invincible in international competition. [0003] The underwater vehicle is driven by a diesel engine. During normal operation, a part of the exhaust pipe is located underwater and a part is exposed to the water surface. Rainwater enters the exhaust pipe, and if it is submerged in an accident, the seawater wil...

AI Technical Summary

Problems solved by technology

[0003] The underwater vehicle is driven by a diesel engine. During normal operation, a part of the exhaust pipe is located underwater and a part is exposed to the water surface. Rainwater enters the exhaust pipe, and if it is submerged underwater, the seawater will directly pour into the exhaust pipe, causing the high-temperature diesel engine to blow up, damage, and the aircraft to sink, resulting in major safety accidents and economic losses

Considering that on the one hand, the exhaust port is located at the highest point of the water surface of the aircraft, the weight has a great influence on the heavy buoyancy center, and the weight should be as small as possible; The rubber sealing structure cannot be realized, and the harsh working conditions bring certain difficulties to the design

At present, there is no effective solution for the protection device of high temperature exhaust port in China
