Abstract

The invention discloses a device and a method for measuring ship draught. The measuring device comprises an organic glass tube with scales, wherein a handle is connected with the upper part of the organic glass tube; the handle is located in a horizontal position; a moveable hand shank is mounted on the handle; a steel wire rope is fixedly connected with the moveable hand shank; a steel wire rope entering hole is formed in the top of the organic glass tube; the steel wire rope enters the organic glass tube through the steel wire rope entering hole and is connected with a water inlet valve device arranged at the bottom end of the organic glass tube. The measuring method comprises the following steps: selecting a water gauge mark on the water surface as a standard; inserting the organic glass tube into water; holding the moveable hand shank; after water in the organic glass tube is aligned with the water surface, releasing the moveable hand shank; taking the measuring device out of the water and reading the number; calculating the ship draught value. According to the invention, the problems of complex work, low precision and limitation from objective conditions, such as, sea waves, weather, of the ship draught measurement are effectively solved.

Description

technical field [0001] The invention relates to a device for ship draft measurement. Background technique [0002] With the continuous development of the shipbuilding industry, various new technologies and new equipment are continuously introduced into the shipbuilding process, making the speed of shipbuilding faster and faster. How to ensure safety at a faster pace of production is becoming more and more popular. Pay attention to. [0003] As we all know, before the delivery of the ship, it is necessary to measure the draught of the ship with bare ship. At present, the traditional visual method is still widely used in the world and at home. There are many defects and limitations in this method. The staff, the shipowner and the ship inspector ride on the small boat, which is limited by the angle of view, line of sight, weather conditions, wave conditions and other conditions, so the accuracy of observation is difficult to be accurate, which leads to the postponement of the ...
