Description

Portable wave-avoiding draft mark accurate reading cylinder measuring scale

Technical Field

The utility model relates to the technical field of ship appliances, in particular to a portable wave-avoiding draft mark accurate reading cylinder measuring scale.

Background

New vessels are built, and when a series of vessels are built, they are also called series of bow vessels, including bulk carriers (BC vessels), container vessels (cargo), car carriers (PCTC vessels), floating liquefied natural gas vessels (FPSO vessels), etc., which are hereinafter collectively called pilot vessels. Before the construction of the pilot ship is completed to the ship, the pilot ship needs to be subjected to a tilting experiment and a loading capacity test, so that the empty ship weight and the gravity center position of the pilot ship are obtained through calculation. In the load capacity test process, an experimenter is required to accurately read six draft values of a pilot ship, namely, a port side and a starboard side, which are close to a bow, a midship and a stern, and in order to improve the calculation accuracy of pitching and transversely tilting of the pilot ship in an ideal experimental water area (enclosed water area space) still water ship state, the draft values are required to be accurate to two decimal places. The draft scale of the experimental ship is mainly read by naked eyes, only one decimal place later, and the read reading has larger deviation from the actual draft value and larger influence of human factors because the sight line of an experimenter is difficult to be horizontal to the draft position. Two experimenters and a class society personnel in a general draft reading link can reach about 0.5 m through the draft ruler error read by naked eyes, and the readings cannot be used for calculating parameters for reference, so that measurement is needed by a measuring ruler with higher accuracy, when the accurate measuring ruler is adopted for measurement, the experimenters need to be carried by a small working boat to be close to draft rulers on outer plates on two sides of the experimental boat, and then the measurement is carried out through a straight ruler, so that a plurality of difficulties are encountered in the measurement process: 1. the ship outer plate is generally provided with radian, and the hard ruler cannot be completely attached to the ship outer plate for measurement; 2. the position of the datum point is difficult to fix, although the position is in a relatively ideal experimental water area, the experimental ship and the small working boat can generate small heave and roll motions, the hard measuring scale is difficult to be parallel to the water surface, and the draft reading obtained under the condition is inaccurate; 3. at the position where the ruler body is contacted with the water surface, irregular small waves exist in the water, the water surface is fluctuated up and down, the period of the test staff for confirming the reading is prolonged, and the obtained reading still cannot meet the accuracy of calculation requirements.
