The stability and buoyancy of the ship can change along with the change of the water inflow. After a ship is damaged, the ship body inclines due to asymmetric distribution of water on two side sides, and crews can continue to maintain stability only by performing damage management operations such as leaking stoppage, drainage and the like at the first time, so that the irreversible effect is avoided. Therefore, how to delay water inflow and control the water inflow after the ship breaks has important significance for damage management operation and personnel escape.
The ship breaking cabin is divided into three states according to the cabin water inlet condition: in the first situation, a ship body is damaged under the action of explosive impact load, seawater flows into a cabin through a crevasse, but the crevasse is below the horizontal plane and the cabin top is not damaged, the cabin is completely immersed by water, and the water inlet volume is only the cabin volume; when the seawater flows into the cabin through the break opening, the water in the water inlet cabin is not related to the seawater outside the ship, and the free liquid level in the damaged cabin is the second condition; the third is the most common water inlet mode of the cabin breaking, the top of the break is above the water surface, the bottom of the break is below the water surface, the water line in the cabin and the sea level outside the naval vessel are kept at the same horizontal plane, the water inlet amount can also change along with the inclination of the naval vessel, finally the water line is inclined to a new balance position, and the liquid level in the cabin is kept consistent with the sea level outside the cabin. When a ship sails in the sea, the ship can be detected and prevented from striking reefs and colliding through communication equipment such as radars and sonars, but the research on how to keep the ship stable and sinking resistance under the condition that the ship is damaged by underwater weapon attack is of great significance.

FIG. 1 is a schematic view of the installation location of the present application;
fig. 2 is a schematic diagram of the working principle of the present application.
Detailed Description
The first embodiment is as follows: the embodiment is described with reference to fig. 1-2, and the control device for delaying water inflow and inhibiting sinking of the explosion cabin of a ship comprises a controller 13, a monitoring device 3 and a ventilation device 1, wherein the monitoring device 3 comprises a plurality of sensors 4 which are sequentially arranged on the inner wall of a watertight cabin 2 from high to low, and the plurality of sensors 4 are electrically connected with the controller 13;
the ventilation equipment 1 comprises an air pump 9, a ventilation pipeline 6 and a ventilation valve 7, wherein the air pump 9 is fixedly connected with a deck 8 and is arranged at the upper part of the watertight cabin 2, the ventilation pipeline 6 penetrates through the deck 8 and is communicated with an inlet of the air pump 9, the ventilation valve 7 is arranged on the ventilation pipeline 6, and the ventilation valve 7 and the air pump 9 are respectively electrically connected with a controller 13.
Several sensors 4 are arranged at different heights to feed back different water level information. The controller 13 adjusts its operating position according to the information transmitted by the various sensors 4 to control the intensity of operation of the ventilator 1. The low position sensor 4 corresponds to the low gear of the controller 13, the high position sensor 4 corresponds to the high gear of the controller 13, each gear corresponds to the corresponding ventilation flow and ventilation rate, the higher the water level is, the higher the gear is, the higher the ventilation speed is, and the ventilation volume is larger. When the sensors 4 with different heights all feed back water level information, the priority of the high gear is higher than that of the low gear. If the water level is submerged to the highest sensor 4, the ventilation device 1 automatically changes to the ventilation volume corresponding to the highest sensor 4; similarly, when the water level is lowered to the next sensor 4, the gear is lowered to the corresponding gear. Therefore, the water level can be ensured to fluctuate at a stable height under the condition that the explosion breach is not known to be large and the highest point is high.
The splashing of the liquid drops does not trigger the sensor 4 at the high position, the controller 13 needs the free liquid level to exceed the sensor 4 to trigger, and the sensor 4 feeds back a signal to the controller 13 due to the change of the ambient pressure.
The connection part of the air pump 9 and the deck 8 is watertight.
The controller 13 receives the signal of the sensor 4 to control the ventilation valve 7 to be opened, and the air pump 9 also receives the signal of the controller 13 to directly transmit the outside air to the watertight compartment 2. The air pump 9 works to directly deliver the outside air into the watertight compartment 2 through the ventilation duct 6 without additionally arranging an air generator. The introduced gas is gathered above the watertight cabin 2, the seawater inflow amount is reduced, the shaking damping of the ship body is increased, the water inflow rate is delayed, and the ship is effectively prevented from heeling or even sinking.
The electric coupling mode between each structure in this application is waterproof wire 14. And the entire device requires full waterproofing.
In the case of no breach of water, the vent valve 7 is closed and the vent line 6 is not open. The cabin is completely watertight when the ship safely sails.
The ship is exploded to damage and brings the topside breach to the naval vessel, and the sea water gushes into the cabin section condition of intaking, therefore the device of this application arranges in watertight cabin 2.
The outlet of the air pump 9 is communicated with a plurality of air outlet pipes 11, and the air outlet pipes 11 are arranged in an umbrella shape. So design, a plurality of outlet ducts 11 of umbelliform arrangement can make the gas outlet dispersion, and then make the area of ventilating bigger, more even extrusion free liquid level. Avoid because of the gas vent undersize, the gas rate of ventilating is too fast leads to under the high water level condition that gas directly strikes free liquid level, aggravates the disturbance of free liquid level.
The plurality of outlet pipes 11 are externally covered with a bell-shaped protection cover 15.
An alarm 10 is arranged on the air pump 9. By the design, the air pump 9 works to drive the alarm, so that a crew can know the position of the damaged cabin at the first time, and the subsequent damage management work is facilitated.
The bottom of the air pump 9 is provided with a camera 12. So design, alarm and camera all link to each other with the controller, can make the crew of the ship can observe the condition of intaking in the cabin without getting into the cabin, can manually adjust the operating gear of air pump 9. The camera 12 may be a night vision camera 12 or a lighted camera 12 for easy viewing.
The outside of every sensor 4 all is equipped with safety cover 5, safety cover 5 covers the outside of establishing at sensor 4, and sealed the setting. So design, can prevent shock wave and detonation product and high-speed fragment direct action on sensor 4 through setting up safety cover 5, and then prevent sensor 4's malfunctioning. The protective cover 5 is welded with the bulkhead of the watertight cabin 2.
The protective cover 5 is of an arc structure. By the design, the sensor 4 is protected from being damaged by the bending resistance of the arc-shaped structure, and the flight tracks of detonation products and fragments are influenced and changed.
The outer wall of the protective cover 5 is coated with a waterproof layer.
When a large crevasse is generated on the side or the bottom of a board to cause water to enter the watertight cabin 2, the controller 13 controls the ventilation valve 7 and the air pump 9 to start according to signals fed back by the sensor 4 with different height positions submerged by the water level, the air pump 9 introduces outside air into the water level of the watertight cabin 2 through the ventilation pipeline 6, and along with the accumulation of introduced air above the water level, the seawater inflow amount is reduced, the shaking damping of a ship body is increased, and the cabin water inlet speed is delayed.
