Bulk carriers are specially used for transporting non-bandaged goods, such as coal, ore, wood, livestock, grains, and the like. A ship for bulk transportation of bulk dry bulk cargoes such as grains, coal, sand, salt, cement, etc. The whole cargo area of the bulk carrier is provided with large ballast tanks from the fore to the aft to coordinate with adjusting the sailing draft state of the ship. The ballast tanks of large bulk cargo vessels are divided into top and bottom ballast tanks. Because ocean going vessels have long voyage times, large fuel tanks are required to be equipped to load fuel for fuel supply, and in order to facilitate pipeline laying, a top pressure cargo tank near the tail end is generally selected as the fuel loading tank. The loading capacity of the cabin is currently measured by adopting two modes of a liquid level telemetry system and a sounding pipe, the liquid level telemetry system is provided with an induction signal in the cabin, and the induction signal is transmitted to a computer terminal through an electric signal, so that the loading number of the cabin can be generally judged, and the accurate measurement can not be realized. And the fuel oil buying and selling relates to economic traffic, more accurate measurement results are needed, and currently, the accepted mode of the buyers and sellers is to measure through a sounding pipe by adopting a sounding ruler. Due to the special nature of the vessel structure, the normal draft condition of the vessel is a tail tilt, so the arrangement of the sounding pipe needs to be arranged as far as possible at the tail end. The lowest points in the cabin are all in the same height value under the influence of the ship body structural form, so that certain liquid level accumulation exists in the cabin all the time, and the liquid level measured by the sounding ruler cannot be accurately and practically fed back to an actual liquid level value in the cabin. Therefore, there is a need for a depth gauge to be positioned below the lowest position within the cabin.
The ship top cabin structure is divided into a main deck, a top cabin sloping plate and an outer plate. Wherein, the lowest point of the cabin is the intersection point of the outer plate and the sloping plate of the top side cabin. The depth measuring pipe is affected by the outer plate aggregate and is arranged on the inner side of the outer plate aggregate, and a certain blind area is formed at the position, away from the lowest point of the cabin, of the low point of the depth measuring pipe, so that the depth measuring pipe cannot be measured.
