Embodiment 1

[0053] Such as Figure 1-10 As shown, a quick recovery device for liquid cargo of a sunken ship includes: a disengagement device composed of a quick recovery valve for liquid cargo of a sunken ship and a docking quick connector. The road system is connected with the liquid cargo tank, and the liquid cargo inside the liquid cargo tank is discharged as soon as possible by relying on the effective cooperation of the underwater robotic arm in the underwater environment with high pressure and low visibility. The two ends of the docking quick connector are respectively connected with the wreck liquid cargo quick recovery valve and the rescue ship liquid cargo recovery pipeline (rescue ship liquid cargo recovery pipeline is the prior art, not shown in the figure), the docking quick connector and the underwater mechanical arm connected (the underwater robotic arm adopts the existing structure, not shown in the figure), and the fast docking and disengagement of the docking quick connec...

Embodiment 2

[0063] On the basis of Embodiment 1, the present invention also provides a recovery method of a sunken ship liquid cargo fast recovery device, comprising the following steps:

[0064] Step 1. Before the rapid recovery of the liquid cargo of the sunken ship, the quick recovery valve of the liquid cargo of the sunken ship forms an absolute seal under the force of the internal liquid cargo and the first return spring 10, and the docking quick connector is also formed under the action of the second return spring 14 Absolutely sealed; when the rapid recovery of liquid cargo from a sunken ship starts, the quick docking joint will be brought to the vicinity of the guide mechanism 5 of the quick recovery valve for liquid cargo on a sunken ship under the action of the underwater mechanical arm. Since the guide mechanism 5 has a certain The arc-shaped guide does not need to be carried by the underwater robot arm to accurately send the docking quick connector into the wreck liquid cargo q...

Abstract

The invention provides a quick recovery device for sunken ship liquid cargoes and a recovery method thereof. The device comprises a disengaging device composed of a sunken ship liquid cargo quick recovery valve and a butt joint quick connector, wherein the sunken ship liquid cargo quick recovery valve is arranged at the position of a liquid cargo tank of a liquid cargo ship, the two ends of the butt joint quick connector communicate with the sunken ship liquid cargo quick recovery valve and a rescue ship liquid cargo recovery pipeline correspondingly, and the butt joint quick connector is connected to an underwater mechanical arm. Quick butt joint and disengagement of the butt joint quick connector and the sunken ship liquid cargo quick recovery valve are operated through the underwater mechanical arm; during butt joint, the liquid cargo tank and the rescue ship liquid cargo recovery pipeline are connected, so that quick recovery of the sunken ship liquid cargos is achieved; and return springs are arranged inside the sunken ship liquid cargo quick recovery valve and the butt joint quick connector correspondingly, the butt joint quick connector is automatically and quickly disengaged from the sunken ship liquid cargo quick recovery valve under the action of the underwater mechanical arm when unclear severe conditions are met in deep sea work, and after disengagement, the sunken ship liquid cargo quick recovery valve and the butt joint quick connector are sealed autonomously under the action of the return springs of the sunken ship liquid cargo quick recovery valve and the butt joint quick connector.

Description

technical field [0001] The invention relates to the technical field of ship design, in particular to a fast recovery device for liquid cargo of a sunken ship and a recovery method thereof. Background technique [0002] Nowadays, the maritime transportation industry is constantly developing, and with it, the problems caused by ships to the environment are becoming more and more serious. China is currently the country with the largest total demand for sea transportation in the world. More than 50% of domestic trade transportation and more than 90% of foreign trade transportation tasks are completed by ocean transportation. Due to abnormal climate changes, frequent extreme natural disasters, and human factors, This will greatly increase the probability of major marine accidents and major oil spill pollution risks. The damage caused by oil pollution to the marine environment is more prominent and serious. In addition, marine pollution caused by accidents such as ship collision,...
