An exhaust and anti-wave anti-water device

Abstract

The invention provides a device for preventing waves and water for exhaust, which can prevent waves and stop water for exhaust pipes, and prevent water from entering equipment from the exhaust pipes. The device includes an exhaust elbow, an anti-wave shell, a hinge, a sliding mechanism, a water baffle and a float, and the peripheral equipment is an exhaust pipe. An installation hole for connecting with the exhaust port of the exhaust pipe is processed on the right side of the shield; an exhaust hole is processed on the arc surface, and one end of the exhaust hole is connected to the water baffle through a hinge. The float and guide mechanism are located inside the shield, and one side end surface of the float closely fits the end surface A of the shield. When water enters the shield from the opening on the bottom of the shield, the float floats up along the sliding mechanism to block 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
