Problems solved by technology
Each ballast tank needs to be connected through pipelines. When arranging ballast pipelines, the ballast pipes need to run through the closed compartments at the bottom of the ship, and ro-ro passenger ships have high requirements on the safety of the ship. The safety requirements are also relatively stringent. In order to meet the damage stability requirements, additional protective elements need to be added to the ballast pipeline. The configuration of these elements will lead to an increase in the construction cost of the ship; Therefore, it is necessary to install a ballast water treatment device, which will also lead to an increase in the cost of ship construction

The invention belongs to the technical field of ships and discloses a ship body ballast structure, a ship and a stern inclination angle adjusting method. The ship body ballast structure comprises an oil tank, a sliding rail, a fresh water tank and a weight detection assembly; the oil tank is configured to load fuel oil providing power for a ship; the sliding rail is arranged in a ship body in thelength direction of the ship body; the fresh water tank is configured to load fresh water used and ballasted on the ship; and the fresh water tank can move along the sliding rail; the weight detectionassembly is configured to detect the weight of the fuel oil in the oil tank and the weight of the fresh water tank. According to the ship body ballast structure, the gravity center of the ship can beflexibly adjusted; according to the ship, the ship body ballast structure is arranged on the ship body; the stern inclination angle of the ship body can be flexibly adjusted; and construction cost islow. With the stern inclination angle adjusting method adopted, the floating state of the ship body can be adjusted in real time, and normal operation of the ship is guaranteed.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to a ballast structure of a ship hull, a ship and a method for adjusting the stern inclination angle of the ship body. Background technique [0002] Generally, when a ship is in normal operation, it is necessary to ensure a certain stern angle (the draft at the stern of the ship is greater than the draft at the bow), but with the consumption of fuel and fresh water, the floating state of the ship will change, resulting in the ship not being able to meet the reasonable stern angle. Therefore, a ballast structure needs to be installed on the ship to adjust the floating state of the ship. [0003] For ro-ro passenger ships, the amount of ballast water required to adjust the floating state is generally not large, so the number of ballast tanks is small, but the arrangement is scattered along the length of the ship. Each ballast tank needs to be connected through pipelines. When arranging...
