Observation device for water gauge of ship

Abstract

The invention provides an observation device for a water gauge of a ship. The observation device comprises a transparent pipe, wherein a curve-shaped wave resistant pipe is connected to the tail part of the transparent pipe, and the diameter of the curve-shaped wave resistant pipe is smaller than that of the transparent pipe; an electromagnet, a camcorder lens and magnifying glass are sequentially arranged at the upper part of the transparent pipe from top to bottom, the electromagnet is electrified through a power supply device on the ship, and the camcorder lens is connected with an image display system on the ship. Through the adoption of the observation device disclosed by the invention, a measurer does not need to go down to the water surface, so that the draught depth of the ship can also be observed, interference of waves on the water surface is avoided, the safety of observing the draught situation of the ship is greatly improved, and besides the accuracy of reading the water gauge is improved.

Description

technical field [0001] The invention relates to a ship appliance, in particular to a ship water gauge observation device. Background technique [0002] The transportation of bulk cargo such as coal, iron ore, grain, etc. is an important part of water transportation, and the accuracy of measurement is directly related to the economic interests of all parties; method of measurement. [0003] Water gauge weight measurement is to calculate the draft of the ship by observing and reading the water gauge at multiple parts of the carrier ship, calculate the buoyancy of the ship, and then obtain the weight of the cargo loaded on the ship. The traditional method of visually reading the water gauge has the following disadvantages. First, it is limited by the size of the waves on the water surface. The larger the waves, the lower the accuracy of the readings. For example, for a 50,000-ton bulk carrier, the TPC of the ship (per cm displacement) is generally about 60 tons / cm, and an err...

Problems solved by technology

The traditional method of visually reading the water gauge has the following disadvantages. First, it is limited by the size of the waves on the water surface. The larger the waves, the lower the accuracy of the readings. For example, for a 50,000-ton bulk carrier, the TPC of the ship (per cm displacement) is generally about 60 tons / cm, and an error of 1 cm in the reading of the water gauge will cause an error of about 60 tons in the weight of the cargo

The second is that it is very inconvenient to visually measure the water gauge. Generally, small boats are hired, and the surveyors take the small boat close to the water gauge to observe and read.
