Low-flow-resistance water cannon preventing device for chimney exhaust pipe

Abstract

The invention discloses a low-flow-resistance water cannon preventing device for a chimney exhaust pipe. The low-flow-resistance water cannon preventing device comprises a top water retaining cover, alateral annular water retaining shell, an exhaust drainage shell, a water drain pipe, a structural skeleton and an exhaust pipe opening cover ring. The exhaust drainage shell is connected with the top water retaining cover and shielded by the top water retaining cover; the top water retaining cover is mounted on the structural skeleton; the lateral annular water retaining shell is mounted on thestructural skeleton; the structural skeleton is mounted on a base at an outlet of the chimney exhaust pipe, and the outlet of the chimney exhaust pipe is shielded by the top water retaining cover; thewater drain pipe is connected with the exhaust drainage shell; and the exhaust pipe opening cover ring is mounted on the chimney exhaust pipe to shield a gap between a chimney sealing plate and the chimney exhaust pipe. According to the low-flow-resistance water cannon preventing device for the chimney exhaust pipe, sprayed water can be effectively blocked from being injected into the exhaust pipe while normal exhaust of a diesel engine is guaranteed.

Description

technical field [0001] The invention relates to the design of official ships, in particular to a low-flow resistance water cannon device for chimney exhaust pipes. Background technique [0002] China has nearly 3 million square kilometers of "marine land", including the exclusive economic zone under China's jurisdiction and a continental shelf area of ​​2.6 million square kilometers. The task of safeguarding maritime rights and interests is increasingly heavy. [0003] In recent years, local maritime disputes and frictions between our country and ships from neighboring countries have been increasing. Law enforcement and confrontation by official ships on the sea have become normalized. Ships from various countries have begun to equip non-lethal weapons with low-intensity confrontation—water cannon devices. . During the confrontation, the ships of both sides sprayed each other with water cannons to avoid it. [0004] At present, the range of water cannons equipped on ships ...

AI Technical Summary

Problems solved by technology

The water cannon is aimed at the outlet of the exhaust pipe to spray, and the concentrated and super-large flow of water injection far exceeds the original water-repelling capacity of the exhaust pipe. Once the water injection enters the exhaust pipe, it is easy to cause the main engine to stall and shut down, and in severe cases, it may even flow back into the body inside, resulting in problems such as cylinder chilling damage, cylinder scuffing and corrosion
