Ship ballast water exchange device with mobile and telescopic snap-in barrier airbag

Abstract

The invention discloses a ship ballast water exchange device with clamping type preventing an air bag from moving and stretching function, which comprises a sail, a hull, a water treatment device, a sail fixed column, a water carrying chamber; the sail fixed column is fixed to the hull; the sail fixed column is provided with the sail; the sail fixed column is fixed to the sail; the water carryingchamber is formed in the bottom of the hull and is integrated with the hull; the water treatment device is installed in the water carrying chamber. The device has the advantages of separating the newballast water from the original ballast water through the air bag plate, thus effectively avoiding the mixing of the new ballast water and the original ballast water; using the amount of the new ballast water to push the air bag plate to the direction of discharge so as to achieve the gradual replacement of the ballast water, thereby solving the problem that the original ballast water and the newballast water mix so as to result in some of the original ballast water cannot be discharged.

Description

technical field [0001] The invention relates to the field of ship water treatment equipment, in particular to a ship ballast water exchange device with movable and telescopic snap-in barrier airbags. Background technique [0002] The ship needs to carry ballast water in the process of transportation. Through the cooperation of ballast water pump, ballast water pipeline, ballast tank and related valves, according to the needs of ship operation, the ballast tank of the whole ship is injected or discharged to achieve adjustment. The draft of the ship and the longitudinal and lateral stability of the hull and the safe metacentric height; reduce the deformation of the hull, so as not to cause excessive bending moment and shear force, and reduce the vibration of the hull; the purpose of improving the seaworthiness of the empty cabin, the current ship Water treatment equipment has the following defects: [0003] Properly add or discharge the ballast water in the ship according to ...

AI Technical Summary

Problems solved by technology

[0003] Properly add or discharge the ballast water in the ship according to actual needs to ensure the normal operation of the ship. When the ballast water in the ship needs to be replaced, the drain valve and the water inlet valve need to be opened at the same time. It can ensure the stable transportation of the ship, but when the traditional replacement method opens the drain valve and the water inlet valve at the same time, it is easy to mix the original ballast water with the new ballast water, resulting in part of the original ballast water not being discharged
