AI Technical Summary

Technical Problem

Existing vent pipes are prone to damage, allowing seawater or rainwater to enter the emergency diesel fuel tank, affecting the normal operation of the emergency generator.

Method used

A ventilated structure was designed, including a first ventilator and a second ventilator. The vertical section of the first ventilator extends out of the deck and is covered with a rain cover, while the inclined section is connected to the drain pipe. The second ventilator is bent and connected to the first ventilator. The drain pipe is equipped with an S-shaped water trap and a water storage tray to prevent seawater or rainwater from entering the day-use cabinet.

Benefits of technology

It effectively prevents seawater or rainwater from entering the daytime cabinet, ensuring the stable operation of the emergency generator. It has a simple structure, is easy to maintain, and is low in cost.

Abstract

This utility model relates to the field of marine emergency equipment technology, and in particular to a ventilated structure for an emergency diesel fuel tank. The structure includes a first vent pipe, a second vent pipe, and the emergency diesel fuel tank. The vertical section of the first vent pipe extends vertically upwards and exits the deck above the emergency generator room. A rain cover is installed at the top opening of the vertical section of the first vent pipe. The inclined section of the first vent pipe extends downwards within the emergency generator room and connects to a drain pipe. Both the second vent pipe and the emergency diesel fuel tank are located within the emergency generator room. The second vent pipe connects to the emergency diesel fuel tank and extends upwards. At its extended end, the second vent pipe bends downwards and connects to the inclined section of the first vent pipe. Even if seawater and rainwater enter the first vent pipe through the damaged section, they cannot flow into the emergency diesel fuel tank, thus better ensuring the stable operation of the emergency generator.
