Leaked liquid cargo collecting device suitable for low-temperature liquid cargo tank

Abstract

The invention discloses a leaked liquid cargo collecting device suitable for a low-temperature liquid cargo tank, and belongs to the technical field of liquid cargo tank leaked liquid cargo treatment. The leaked liquid cargo collecting device comprises a fluid director, a fluid guiding cavity is formed in the fluid director, and a liquid inlet and a liquid outlet which communicate with the fluid guiding cavity are formed in the fluid director; the liquid collecting container is arranged below the fluid director and is provided with an upper opening matched with the liquid outlet; the plugging head is arranged in the flow guide cavity; and the elastic reset mechanism is arranged in the flow guide cavity, connected with the plugging head and used for driving the plugging head to move or enabling the plugging head to plug the liquid inlet. Leaked liquid goods in the leakage channel can be drained into the liquid collection container through the fluid director, and collection of the leaked liquid goods is achieved; the acting force of the elastic reset mechanism on the plugging head drives the plugging head to move and plug the liquid inlet of the fluid director, sealing of the leakage channel is achieved, a dry non-combustible environment is formed in the leakage channel, and the use safety of the liquid cargo tank is improved.

Description

technical field [0001] The invention relates to the technical field of handling liquid cargo leaked from a liquid cargo tank, in particular to a leaking liquid cargo collection device suitable for low-temperature liquid cargo tanks. Background technique [0002] A liquefied gas carrier is a ship used to transport cryogenic liquefied gas cargo. When a liquefied gas ship is sailing at sea, there may be unforeseen leakage of low-temperature liquid cargo in the cargo tank. The leaked low-temperature liquid cargo (referred to as leaked liquid cargo) will greatly reduce the local temperature of the hull, resulting in failure of the hull structure, thereby affecting the safety of the ship. Therefore, it is necessary to divert the leaked liquid cargo to a designated area for collection and safe disposal. [0003] The patent document with the notification number CN109204709A discloses a leaking liquid collection device for a liquid cargo tank. The collecting device guides the leaked...
