Ship-sinking-preventing expansion device

Abstract

The invention provides a ship-sinking-preventing expansion device which includes a ship body, an outer ship plate and an inner ship plate, the outer ship plate and the inner ship plate are both weldedto the bottom of the ship body, and the outer ship plate is welded to the outer side of the inner ship plate, a first box, a second box, a third box and a high-pressure water pump are welded to the inner ship plate, a spray pipe is welded to one end of the high-pressure water pump, a return pipe is welded to the top of the inner ship plate, and first solenoid valves are installed at the two endsof the return pipe; and support rods are welded to the outer ship plate, a vibration sensor is installed on the outer ship plate through bolts, a three-way valve is installed on the return pipe, an intelligent processor is installed on one side of the high-pressure water pump through bolts, an impeller is installed on the inner side of the high-pressure water pump, a connecting pipe is welded to one side of the third box, and an inlet pipe is welded to the other side of the high-pressure water pump. The ship-sinking-preventing expansion device is reasonable in design and more convenient to useand is suitable for installation on the inner side of the ship body to prevent the ship body from water leakage and sinking.

Description

technical field [0001] The invention relates to the field of anti-wreck expansion devices, in particular to an anti-wreck expansion device. Background technique [0002] The hull is the basic part of the ship, which can be divided into the main part and the superstructure part. The main part generally refers to the part below the upper deck. It is a hollow body with a specific shape surrounded by the hull (bottom and side) and the upper deck. It is a key part to ensure that the ship has the required buoyancy, navigating performance and hull strength. . The hull is generally used for arranging power plants, loading cargo, storing fuel oil and fresh water, and arranging various other compartments. In order to ensure navigation safety, the existing hull structure mostly adopts a double-layer structure, so that after the outer plug is damaged by collision, the inner one The hull can still protect the safety of people and cargo on board, and has the characteristics of simple st...

Problems solved by technology

The hull is generally used for arranging power plants, loading cargo, storing fuel oil and fresh water, and arranging various other compartments. In order to ensure navigation safety, the existing hull structure mostly adopts a double-layer structure, so that after the outer plug is damaged by collision, the inner one The hull can still protect the safety of people and cargo on board, and has the characteristics of simple structure, convenient processing, firm structure, high safety, strong durability, and low equipment cost, and can meet the existing safety requirements for ship navigation. As far as the anti-sinking device of the double hull of the existing ship is concerned, on the one hand, after the collision, water will be poured into between the two layers of hull through the hole of the collision, thereby greatly increasing the weight of the hull, and this At the same time, the inner ship plate bears the pressure of the bottom of the water, which makes it difficult for the hull to continue sailing. On the other hand, in the process of transporting the water-blocking material, it is necessary to mix the expansion agent and the hydrogel evenly. The ordinary transport shaft does not It can effectively mix the expansion agent and the hydrogel evenly, which is not conducive to the function of the water-blocking material. On the other hand, after the delivery of the hydrogel is completed, some residual liquid is easy to remain in the pipeline, which is easy to block the pipeline , is not conducive to reuse
