Multifunctional hatch cover and ship

Abstract

The invention relates to the technical field of ships, in particular to a multifunctional hatch cover and a ship. The multifunctional hatch cover comprises a cover plate and a steam hose switching assembly, wherein the cover plate is detachably arranged on the opening of a cargo tank in a detachable mode, so that a tank washing machine can enter the cargo tank from the opening of the cargo tank; the steam hose switching assembly comprises a transferring part and a blowing part which are connected with each other, the transferring part is located outside the cargo space and can be connected with a steam hose of the tank washing machine, the blowing part is configured to penetrate the cover plate and is in sealed connection with the cover plate, steam provided by the tank washing machine canenter the cargo tank through the steam hose and the transferring part in sequence, so that the escape of oil gas or high-temperature steam in the tank can be avoided, and the harm to a human body isreduced. According to the ship, by applying the multifunctional hatch cover, the multifunctional hatch cover can be simultaneously suitable for cleaning in the cargo tank and steam cleaning outside the cargo tank; and when the steam is adopted to clean the cargo tank, the escape of oil gas or high-temperature steam in the tank can be avoided, and the harm to the human body is reduced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a multifunctional hatch cover and a ship. Background technique [0002] All compartments of the ship need to be equipped with hatch covers for easy cleaning. For cargo tanks containing chemicals / oil tankers, in order to ensure the safety of operations in the tanks, reduce and prevent marine hazards, reduce hull corrosion and improve operational efficiency, it is usually necessary to use tank cleaning machines to clean the cargo tanks. [0003] Cleaning the cargo hold with a tank washing machine usually includes the following cleaning methods: 1) Place the tank washing machine in the cargo tank and use high-pressure washing liquid for cleaning. This scheme should ensure that the tank washing machine can enter the cargo tank, so the hatch cover of the cargo tank The size is generally large; 2) Place the tank washing machine on the deck outside the cargo hold and use high-temperature...
