Deep stirring ship self-balancing system and method

Abstract

The invention discloses a deep stirring ship self-balancing system and method. The system comprises a pipeline system and an automatic control system, wherein the pipeline system comprises tilt-adjustable water ballast spaces, a tilt-adjustable pump unit, a pipeline and valves; the automatic control system comprises a draft sensor, a tilt meter, a liquid level switch and a PLC control system. The liquid level of each tilt-adjustable water ballast space is adjusted by virtue of the obtained draft levels at four corners of the bottom of the deep stirring ship measured by the draft sensor, the liquid level of each tilt-adjustable water ballast space detected by the liquid level switch and the inclination angle and inclination direction detected by the tilt meter, so that the liquid level reaches a liquid level set value enabling the deep stirring ship to restore to a balancing position. With the adoption of the system or method disclosed by the invention, when the ship transversely tilts and longitudinally tilts, rapid, accurate and automatically adjustable ship balancing can be realized, so that the ship can be automatically kept balanced under influences of stormy waves and construction operations, and the case that the ship construction safety is threatened due to too large transverse and longitudinal inclination angles is avoided.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an autonomous balancing system and method for a deep mixing ship. Background technique [0002] In the submarine soft foundation reinforcement treatment project, the traditional offshore replacement and filling construction operation is not only difficult to dredge and spoil the soil, but also has a serious impact on the marine environment and the marine aquaculture industry. The deep mixing ship uses cement as the main curing agent. The deep mixing processor installed on the ship will forcefully mix the soft soil and the curing agent in the deep part of the seabed, and form a columnar body with a certain strength through the hydrolysis and hydration reaction of the cement. , the columns and the soil between them jointly support the load to form a composite foundation. [0003] During the construction process, the ship will be affected by the wind and waves, causing heel and trim ...

AI Technical Summary

Problems solved by technology

[0003] During the construction process, the ship will be affected by the wind and waves, causing heel and trim and other swaying; at the same time, when the processor is working underwater, it will also be subject to the reaction force of the seabed, causing the ship to heel and trim; In addition, the mixing piles of deep mixing ships are generally long, poor in rigidity, and generate large moments after being stressed, and are prone to deformation or even damage under alternating loads; these will seriously affect the maneuverability, safety and economy of the ship. big threat
