Abstract

A system for improving stability of a port ship based on coupling of wave diaphragm devices and waves is characterized in that two water bursting pipes and diaphragm boxes form the wave diaphragm devices, the multiple wave diaphragm devices are arranged at intervals along the lower portion of a ship side of the ship, an electric push rod is connected with the diaphragm boxes and a rotation driving device, and the rotation driving device is connected with the ship side; the residual pressure detector and the distance sensor are electrically connected with an attitude system of the ship, the gas pressure sensor is electrically connected with a water pressing system of the ship, the electric push rod is electrically connected with a draught system of the ship, and the rotation driving device is electrically connected with an observation system of the ship. The water pressing system carries out water pressing on the corresponding cabin section according to the triggering direction of the gas pressure sensor, the sensing frequency of the distance sensor and the set value of the residual pressure detector are coupled, the posture of the ship is adjusted, the ship is in the top wave or forward wave state, and therefore loading and unloading stability of the ship under the heavy storm wave condition is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of port ship stabilization, and relates to a system and method for improving the stabilization of port ships based on a wave diaphragm device coupling waves. Background technique [0002] After entering the port, large ships are faced with the problem of loading or unloading, and it is necessary to ensure the stability of the ship to facilitate the loading and unloading of goods. Although some ships use lower anchors to enter the bottom of the water body to stabilize the hull, but during the loading and unloading process, With the increase or decrease of the cargo, the draft of the ship is constantly changing, resulting in a free surface, that is, the draft fluctuates. [0003] In order to ensure the consistency of the ship's draught during loading and unloading, the ship's pressurized water system is used to adjust the double bottom ballast water. The free liquid level is monitored by the ship's draft syst...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a system and method for improving the stability of ships in the port based on the coupling wave of the wave diaphragm device, which consists of two gushing pipes and a diaphragm box Wave diaphragm device, two water inrush pipes are located on the same side of the diaphragm box and communicate with it, the upper and lower water inrush pipes and the diaphragm box are respectively equipped with gas pressure sensors, distance sensors and residual pressure detectors, and multiple wave diaphragm devices are installed along the lower part of the ship's side Arranged at intervals, the electric push rod is connected with the diaphragm box and the rotary drive device, the rotary drive device is connected with the ship's side, the residual pressure detector and the distance sensor are electrically connected with the ship's attitude system, and the gas pressure sensor is electrically connected with the ship's pressurized water system , the electric push rod is electrically connected to the draft system of the ship, and the slewing drive device is electrically connected to the observation system of the ship. In the case of excessive wind and waves, the pressurized water system performs water pressurization in the corresponding cabin according to the trigger position of the gas pressure sensor. And couple the induction frequency of the distance sensor and the setting value of the residual pressure detector, adjust the attitude of the ship to make it in the state of partial top sea or partial sea, so as to ensure the stability of the ship's loading and unloading in the case of strong wind and waves
