A kind of ship draft measuring tool and measuring method using the same

Abstract

The invention discloses a ship draft measuring tool, which comprises a scale tube made of transparent material, two ends of the scale tube are open and one end of the scale tube is provided with a water inlet cover. There is a screw rod, the two ends of the screw rod are arranged beyond the two ends of the scale tube, and the end of the screw rod close to the water inlet cover is fixedly arranged with a sealing assembly. The invention is flexible in on-site operation, which is convenient and quick to read the draft depth during the ship tilting test, and the tool is easy to carry, and the measuring tube can be moved to any position for reading when reading. Because the tool has good sealing performance, it can be used when the tool is moved out of the water surface will not affect its value.

Description

technical field [0001] The invention relates to a ship draft measuring tool and a measuring method using the same. Background technique [0002] In order to regulate the use of ship measuring instruments, the quality department has strengthened the improvement of some inspection instruments, on the one hand, to meet the relevant process specification standards, and on the other hand, to meet the convenience of on-site operation of various inspection instruments. The ship needs to read the draft when doing the inclination test. The wind and waves are small, and the draft size can be read intuitively and accurately. The wind and waves are large, and the reading of the draft is difficult and the error is large. It is necessary to take the average value after multiple readings. Some shipowners It was not approved. Later, a transparent plastic tube was placed next to the water gauge, and the reading was relatively accurate. The shipowner's ship inspection was more acceptable, but...

Problems solved by technology

The ship needs to read the draft when doing the inclination test. The wind and waves are small, and the draft size can be read intuitively and accurately. The wind and waves are large, and the reading of the draft is difficult and the error is large. It is necessary to take the average value after multiple readings. Some shipowners Not approved. Later, a transparent plastic tube was placed next to the water gauge, and the reading was relatively accurate. The shipowner's ship inspection was more acceptable, but because the tooling was clumsy, it was not easy to operate flexibly on site.
