Description
Technical Field
The utility model relates to a cabin capacity curve survey system for measure the cabin capacity curve of boats and ships oil tank.
Background
When a ship is built, because of the restriction of various factors such as building conditions, manufacturing process and the like, the actual oil tank capacity curve of the ship and a design tank capacity curve provided by a design unit often have large deviation; even the initial data design drawing of some ships in the long-term age is lost, so that the hold capacity curve cannot be obtained; and part of designed cabin capacity curves of the ship are designed into a left cabin and a right cabin, but the left cabin and the right cabin are completely communicated in actual use, and the designed cabin capacity curves are combined and have larger deviation with the actual cabin capacity curves. In the prior art, the calculation of the oil tank inventory is converted on the basis of a designed tank capacity curve, so that errors exist between the calculated ship inventory and the actual inventory, and the maximum error number of part of ships exceeds 1 ton. Therefore, if the actual tank capacity curve of the oil tank cannot be grasped, the fuel stock in the oil tank cannot be accurately obtained.
In the prior art, a document with publication number CN105270579A discloses a ship tank stability measurement system and a measurement method, but one of basic data for calculating measurement stability is a tank capacity curve, and if there is no tank capacity curve, the measurement cannot be completed.
Publication No. CN204548469U discloses a monitoring device for marine seawater replenishment type fuel oil system, which also needs to be further analyzed and calculated by combining known cabin volume curves of each fuel oil cabin. The automatic measurement system and the measurement method for the fuel oil storage of the oil tank of the ship with the publication number of CN111238598A have the defects that the process of calculating and drawing the fuel oil curve is very complicated, even sample data needs to be collected on the land, and the inclination of the oil tank is realized by arranging a rotary inclination machine to train a neural network model, which is unrealistic for ships which are built and run on the water surface for many years.
The automatic capacity calibrating device for the irregular ship cabin is disclosed as CN203203650U, and is used for measuring by injecting water into the cabin, but for the ship which is launched, the injected water cannot be allowed in the fuel oil cabin, the measuring efficiency is low, only one ship can be measured at a time, a plurality of ships cannot be measured simultaneously, and the requirements of efficient and rapid measurement cannot be met.
In addition, although a method of calculating a tank capacity curve is also mentioned in the research paper of "tank capacity measurement correction study when a ship is inclined" in the capacity comparison method, this method also requires water injection, and also cannot be actually performed when measurement is performed by the capacity comparison method.
In order to accurately master the inventory number of the oil tanks of the ship, the hold capacity curve of the oil tanks of the ship needs to be accurately mastered. The oil tank capacity curve of most ships is not simple and linear, so that conversion can not be carried out only through the lowest liquid level and the highest liquid level, and a set of channel maintenance ship oil tank capacity curve measuring device needs to be designed to accurately measure the oil tank capacity curve.
