AI Technical Summary

Benefits of technology

This new technology allows for precise measurements on ships' bottoms during different stages such as loading or unloading cargo from trucks at sea ports without affecting their navigation capabilities. It uses multiple levels of liquids (liquid) with specific properties that help determine how deep they sink underwater when loaded onto boats. By dividing these levels separately, we aim to improve accuracy over traditional methods like sonar systems used earlier times.

Problems solved by technology

This patented describes how it works for ships navigating through sea areas with varying levels of water depths due to factors like weight or slope angle. However, there are limitations that affect this method' ability to accurately determine important parameters such as boat loads and vessel movements during navigation.

Embodiment 1

[0030] A method for measuring and correcting a ship's draft depth measuring device in this embodiment is characterized in that the depth measuring device includes a plurality of liquid level sensors, and is divided into two groups, which are respectively installed at the bow 3 and the stern 4 of the ship, They are the bow liquid level sensor 1 and the stern liquid level sensor 2 respectively. The number of the bow liquid level sensors 1 is multiple, at least 2, and they are arranged vertically from top to bottom. The number of position sensors 2 is multiple, at least 2, and they are arranged vertically from top to bottom;

[0031] The measurement and correction method of the depth measurement device is as follows:

[0032] (1) Assuming that the ship does not tilt;

[0033] (1-1) Measurement of ship's bow draft:

[0034] Choose two bow liquid level sensors with different heights, and record them as Am and An from top to bottom. It is known that the measured value of Am is Pm,...

Embodiment 2

[0051] Based on Embodiment 1, a method for measuring and correcting a ship’s draft depth measuring device in this embodiment selects multiple groups of bow liquid level sensors, and the number of each group of bow liquid level sensors is 2. After conversion, multiple Pressure data, take the average value, get The average value is the measured bow average draft; multiple sets of stern liquid level sensors are selected, and the number of stern liquid level sensors in each group is 2, and converted to obtain multiple pressure data, and the average value is taken. have to The average value is the measured mean draft of the stern;

[0052] Under this scheme, even if a small number of liquid level sensors fail, accurate draft data can be obtained.

[0053] In summary, the present invention is simple in structure, reasonable in design, and is used for the measurement of the draft of a boat. Compared with the measurement data obtained by conventional measurement, the measurement d...

Abstract

According to a measuring and correcting method of a ship draft measuring device, the depth measuring device comprises a plurality of liquid level sensors which are divided into two groups, and the twogroups of liquid level sensors are respectively mounted at the bow and stern positions of a ship and are respectively the bow liquid level sensor and the stern liquid level sensor, so that the measuring method is simple, quick and reasonable in design; compared with measurement data obtained through conventional measurement, the measurement data of the device eliminates the influence of the density of water in a water area on the measurement data, the measured draught depth measurement data is more accurate, and meanwhile, the draught depth can be effectively and accurately measured in the inclined state of the ship.
