The present invention relates to a compressed air tank to prevent sinking. When a pressure in the compressed air tank is equal to or lower than a predetermined pressure by a pressure gauge; a switch is operated and the compressed air tank and air are compressed by an air compressor at a fixated pressure. A water sensor with a float switch or a water sensor without the float switch detects water flowing in to a ship such that the switch is turned on when the water flows into the ship as the ship crashes into a rock and sinks. Moreover, a servomotor and the like of a valve rotates such that a valve of a compression tank is opened by the servomotor and the like of the compressed air tank; and the air in the compressed tank is sprayed to a sinking cabin to provide buoyancy by filling air to an air bag which prevents sinking. An outer cover formed of a carbon nanotube and the like is formed on the outside of the air bag to prevent the air bag from being damaged due to the inner goods, objects, and the like. When the water sensor senses the water flowing in, the switch of the air compressor is turned off such that the air compressor cannot operate in a pressure change in the compressed air tank.

Air compressor

[air compressor, air compressor]

A machine that pressurizes air in a tightly closed container to increase its pressure. Electric motors, steam engines, internal combustion engines are used. The mechanism is a reciprocating type by the reciprocating motion of the piston, a rotary type by the rotation of the rotor, a centrifugal type using the centrifugal force of the high speed rotating blades, and a rotary type.

Compressed air

[compressed air, compressed air]

summary

Pressure is applied to reduce the volume of air to high pressure. The high pressure air is used for various works by using the force when the pressure is low, and it is widely used in everyday life. For example, compressed air with a pressure of 0.1 kg / cm 2 is used for subways, mines, and buildings.

The high pressure air is used for various works by using the force when the pressure is low, and it is widely used in everyday life. The pressure is 0.1kg / ㎠ for the subway, the tunnel of the mine and the ventilation of the building, 0.5 ~ 1kg / ㎠ for the coke combustion of the ironworks furnace or casting factory, powder such as cement or pulverized coal, It is about 7kg / ㎠ for air hammer, air drill, rivet hammer, etc., 7kg / ㎠ for braking of railway car or for door engine. / Cm 2, and compressed air of about 50 kg / cm 2 is used for the fuel of the diesel engine.

In addition, the compressed air of 100 to 150 kg / cm 2 is used for submersible suspension of the submarine. A prime mover using compressed air is not used in coal mines or chemical plants where there is a risk of explosion because it does not ignite. Types include steam engine type, star type crank type, forming cylinder type, gear type, and rotary movable blade type.

The sensor that detects water is called Leak Sensor.

A sensor that detects the presence of leaks.

The Leak Sensor has a frequency that is normally

We detect that the frequency is different when there is water.

It's the principle that generates the signal.

Servo Motor

[servomotor]

summary

An apparatus for driving a load (load) by a control signal (control signal) as an operating unit of a servo mechanism.

There are electric (servo motor), pneumatic (air servo motor), and hydraulic (hydraulic motor) according to the power source of the servomotor. In many cases, a servo motor is often referred to as a servo motor.

Servo motor is a control motor with a range of speed response and wide speed control. It is classified as DC servomotor and AC servomotor according to the power source. Most of the AC servo motors are three-phase servo motors.

These are repeatedly operated such as stop, start, reverse, and the like, so that the heat radiating effect is improved and the change of operation is considered in design. The servo motor is operated according to the control signal. To do so, a device for receiving the control signal and amplifying it to drive the servo motor is required, which is called a servo amplifier.

pressure gauge

[manometer, pressure meter]

summary

Instrument for measuring gas or liquid pressure.

Gauge of pressure gauge

There are many kinds of barometers, pressure gauges, high pressure gauges, and vacuum gauges.

The principle of measurement is as follows: ① Measuring the pressure by balancing with the weight of an object (eg liquid column) ② Measuring its size to the extent that the elastic body under pressure is bent, ③ Pressure And to use some kind of physical property that is changed by.

Liquid pressure gauge

A U-shaped pressure gauge with water, mercury, alcohol, etc. in its glass tube is a typical example. When one end of the pipe is connected to the pressure part to be measured, the liquid surface goes up and down to a place where it is balanced with the pressure difference at both ends of the pipe. At this time, The difference in pressure between the tubes can be measured. There are open type (closed type) and closed type (closed type). The range of pressure that can be measured is wide.

The mercury barometer is not a U-shaped tube, but is in principle a closed-tube type liquid pressure gauge like this. In the industrial sector, it is also possible to float a buoy on the surface of the liquid, to extend the movement of the buoy to the machine, or to convert it into an electric quantity (electric quantity).

Elastic pressure gauge

It is relatively widely used for industrial use. Pressure is measured by mechanically expanding deformation of a pressure receiving body made of metal or the like. Bourdon tube type pressure gauges, diaphragm type pressure gauges, bellows type pressure gauges, hollow type pressure gauges (a kind of aneroid barometer). Generally, it is easy to handle and the measurement range is wide. However, the elasticity of the pressure-receiving material is somewhat hysteresis, the deformation is not constant with respect to the pressure, the deformation increases under the same pressure when the pressure is applied for a long time There are common drawbacks.

vacuum gauge

It is a pressure gauge for measuring pressure lower than atmospheric pressure. In addition to liquid pressure gauges and elastic pressure gauges, measurement of particularly high degree of vacuum (1 mmHg or less) requires a gas such as a cloak gauge, a piranha gauge, an ionization vacuum meter, A special pressure gauge is used to measure the change in the thermal conductivity and the ionization degree.

Pressure gauge

It is a kind of high-pressure meter which measures the pressure by weight (minute copper). Pressure gauges, pressure gauges, bourdons, etc., are also available for measuring high pressure fluid.

Measuring is done by balancing the weight of the piston and the weight placed on the piston with the pressure of pushing up the bottom of the piston by drawing oil such as kerosene into the cylinder with the piston. The liquid pressure gauge not only measures high pressure that can not be measured, but also calibrates the scale of other pressure gauge.

A problem to be solved by the present invention is to provide one of the fundamental alternatives to such a cause when there are various causes when a passenger ship sinks.

In the case of Seewal, which sank on April 16, 2014,

According to the story of the accident ship, it started to lean from the left, and then it was completely overturned. What kind of accident do I have to tell you? Is this big ship overturned this way?

There are three possible causes. Once I obtained the drawing, the space beyond this line is divided into several watertight bulkheads. So, in fact, only one space does not lose its stability even when water is submerged. However, in order for an accident to occur, it is possible that several spaces were ripped at once and many spaces were flooded .

1) To provide a fundamental solution to the case where space is torn at one time,

Another condition is that there is a space where there is a passage through which water can move from one space to the other. Now, as for the drawing, several places are connected by stairs. Such a space can cause water to rise up when such space is damaged.

2) To provide a fundamental alternative when there is a passage through which water can move from upper space to upper space

The third is that there is such a space where the reef hits the side, and the vehicle is mounted on a slight upper deck on the side. Such a space is very large and is not divided into any partitions. In such a case, even small damage can lead to a large loss of resilience.

3) To suggest a fundamental alternative in the case of not being divided into bulkheads

Of course, because we have not yet entered deeply, even if turned upside down, if the air is pushed upwards, there will be room for people to survive. However, the fact that most people suffered from this injury was suddenly tilted, which seems to be the reason why some people did not have time to evacuate .

4) To propose a fundamental alternative to allow time for evacuation

The reason for this is that most of the passenger ships and passenger ships are not divided into different categories, and the space is spread widely. Also, the space for loading cargo and cargo is also wide open, so if the water is flooded there, it can be tilted more quickly than other commercial ships and lose balance and become overturned.

3) To suggest a fundamental alternative in the case of not being divided into bulkheads

Such 1), 2), 3) and 4) are problems to be solved by the present invention.

Water sensors, such as compressed air, air compressors, float switches, etc., or water sensors without float switches, air bags, carbon nanotubes, servo motors, etc., The compressed air in the compressed air tank is injected, and the compressed air injected into the air bag is floated without being sunk by the buoyancy formed by the air in the air bag.

The effects of the present invention are as follows: 1) when the space is torn at a time and a lot of space is submerged; 2) there is a passage through which the space can move water to the upper layer; and 3) Can be a fundamental alternative.

1 is a perspective view of the present invention.

FIG. 1 is a perspective view of the present invention. FIG. 1 is a perspective view of the present invention, in which a switch is operated when a pressure gauge is applied to a compressed air tank by a pressure gauge, When the water starts to fill the ship due to the reason that it is sunk due to the reason that the ship is compressed and stored at a constant pressure and the boat strikes the reef, the water sensor by the float switch or the water sensor without the float switch detects water The switch is turned on and the servomotor of the valve opened by the servomotor of the compressed air tank is rotated so that the valve of the compression tank is opened and the air in the compression tank is sprayed and the jetted air fills the air pocket To provide buoyancy to the cabin immersed in the vessel to prevent sinking. The outer surface of the air bag is formed with a casing made of carbon nanotubes or the like, so that the air bag is prevented from being damaged by an inner instrument or a thing. On the other hand, when the water sensor senses that water is flowing, the switch of the air compressor is turned off, thereby preventing the air compressor from operating against the pressure change of the compressed air tank, and the net is formed outside the air bag or outside the carbon nanotube, So that the user can grasp the net and move it.
