Bulk cargo ship cargo hold free liquid level control device

Abstract

The invention relates to the technical field of ships, in particular to a free liquid level control device for a cargo hold of a bulk cargo ship. The control device comprises a stop piece and a vertical rail which are arranged in the cargo hold, the stop piece comprises a vertical plate and a fixing part which are connected with each other, the fixing part is connected to the vertical rail in a sliding mode, and the stop piece can move up and down between an acting position and a preparation position. The vertical plate has a receding state folded at the fixing part and a stopping state extending in the longitudinal direction of the bulk cargo ship, when the stopping piece moves downwards to the acting position, the vertical plate in the stopping state cuts off the free liquid level in the horizontal direction, the bottom of the vertical plate is bent outwards and then bent upwards to form a flow guide part, and the flow guide part and the vertical plate define a flow guide groove. The control device further comprises a liquid storage piece arranged at the bottom of the cargo hold and a connecting pipeline connecting the liquid storage piece and the end of the diversion trench. The safety of the ship is greatly improved, and the control device is simple in structure, small in occupied space, convenient to operate and easy to install and maintain.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a control device for free liquid level in cargo tanks of bulk carriers. Background technique [0002] Bulk carrier is the abbreviation of bulk carrier specially used to transport unpacked goods, such as coal, ore, fertilizer, cement, grain, etc. In recent years, many ships transporting bulk cargo have capsized and sunk. The important reason is that a large amount of water is precipitated during the transportation of bulk cargo, and then the phenomenon of "liquefied flow" of cargo occurs when the ship shakes and bumps in strong winds and waves, and the stability of the ship disappears. overturned. For example, laterite nickel ore is a very special mineral, which is a mineral powder that has condensed moisture. When the water content of laterite nickel ore reaches 35.7%, it starts to flow, and 35.7% is also called the flow moisture point of laterite nickel ore. When the ore When th...

Problems solved by technology

[0005] In order to solve the problem of high fluidity of the free liquid surface when transporting bulk cargo in the cargo hold of the existing bulk carrier, the present invention provides a control device for the free liquid surface of the cargo hold of the bulk carrier, which can cut off the free liquid surface through the stopper And prevent the muddy water in the free liquid surface from impacting the side wall of the cargo hold, which greatly improves the safety of the ship. The control device has a simple structure, takes up little space, and does not affect the loading and unloading operations of the grab bucket. The control device is easy to operate, easy to install and maintain; Steps such as drying and testing are eliminated, which improves the transportation efficiency; the diversion groove can timely guide the moisture precipitated from the cargo into the liquid storage part through the connecting pipeline, reducing the fluidity of the free liquid surface
