Device and method for reading water gauge of a static pressure liquid level gauge to assist ships

Abstract

The invention provides a static pressure type liquidometer auxiliary ship water gauge reading device and method, and relates to the technical field of ships. The static pressure type liquidometer auxiliary ship water gauge reading device includes an outer wall of a ship, above the water surface, and a water gauge on the surface of the outer wall of the ship, wherein a sucker is connected to the outer wall of the ship; a base is connected to the sucker; a platform is hinged to the base; a static pressure type liquidometer is connected to the platform; a measuring rod of the static pressure typeliquidometer is inserted under the water surface; the platform is connected with a pointer; the pointer is aligned with the scale X of the water gauge; the length of the measuring rod is set as L; and the static pressure type liquidometer measures the underwater depth as h, and the length of the measuring rod above the water surface is H, and H=L-h, and the reading of the water gauge is X-H. Thestatic pressure type liquidometer auxiliary ship water gauge reading device solves the technical problem that checking weight by a water gauge in the prior art has a big reading error due to manual reading by eyes, and the operation is inconvenient by the additional devices. The static pressure type liquidometer auxiliary ship water gauge reading device has the advantages of being safe and convenient in ship draught measurement, improving accuracy of water gauge reading, being simple and reasonable in structure, being convenient to carry, being simple in usage and operation, and being suitablefor promotion and application in ship water gauge measurement.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a device and method for reading water gauges for ship draft measurement. Background technique [0002] Water gauge weight measurement is a common practice for waterborne bulk solid goods. Draft weighing includes the measurement of ship draft, the measurement of ballast water tanks, the measurement of fresh water, sewage and marine fuel oil, the measurement of port water density and ballast water density, and data calculation. Among them, the measurement of ship draft, namely Water gauge reading is an important link in the water gauge weighing process. Usually, the readings of the water gauge are generally read with the naked eye, and the error is required to be within 10mm. However, when the wind and waves are strong, the accuracy of the water gauge readings will be seriously affected. Chinese patent application publication number CN103950519A, the application publication date is...
