A marine deck flexible cabin passing device

Abstract

The invention relates to the technical field of ship auxiliary equipment, a marine deck flexible cabin passing device including a rigid base fixedly attached to the deck of the ship, the center of thebase is provided with a central through hole, the upper end of the base is provided with an upper flange of the base, the central through hole of the base passes through a rigid pipeline connected with the equipment in the cabin below the deck, a line flange is arrange on an outer circle of that rigid line at a position above the upper flange of the base, a flexible connecting assembly is connected between the upper flange of the base and the pipeline flange, the flexible connecting assembly comprises a silicone rubber pipe made of silicone rubber and provided with connecting flanges at bothends, wherein the connecting flanges at the two ends are respectively connected with the upper flange of the base and the pipe flange, and the rigid pipe passes through the inner hole of the siliconerubber pipe of the flexible connecting assembly. The invention improves the reliability and safety of the pipeline connection between the ship cargo compartment and the deck.

Description

technical field [0001] The invention relates to the technical field of ship auxiliary equipment, in particular to a ship deck flexible cabin opening device. Background technique [0002] An asphalt carrier is a liquid cargo ship that mainly transports asphalt (petroleum asphalt, coal tar asphalt, etc.) high-temperature liquid cargo. Usually, asphalt ships have to heat the asphalt to a temperature of 160°C or higher during loading and unloading, so the temperature range of the hull and the asphalt equipment installed in the cabin is relatively large during use. [0003] Generally, independent cargo tanks are installed in the cabin of an asphalt ship, and the pipelines connecting the independent cargo tanks need to be arranged on the deck, and the asphalt injection, delivery and monitoring systems need to pass through the deck to connect to the independent cargo tanks. In the prior art, a rigid connection is used between the pipeline connecting the independent cargo tank and ...

AI Technical Summary

Problems solved by technology

In the prior art, a rigid connection is used between the pipeline connecting the independent cargo tank and the hull deck. This rigid connection is prone to the following disadvantages: due to thermal expansion and contraction of the asphalt equipment in the hull and the cabin, the independent cargo tank in the cabin The position of the tank is easy to shift under the action of thermal deformation, which will cause damage to the weld between the pipeline and the hull deck, and damage the tightness of the cabin, thus bringing certain risks to the safe use of the ship
