Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stern funnel device for securing additional container bays,

The present invention relates to a stern funnel device for securing a container bay. More particularly, the present invention relates to a stern funnel device for securing a container bay, and more particularly, to a stern funnel device for securing a container bay, ≪ / RTI >

When cargoes such as natural gas, automobiles, containers, and petroleum are transported, they are generally transported by ship considering transportation efficiency such as transportation cost and transportation time.

In order for the ship to move, a propelling device is required. The propeller plays the same role as above, and a diesel engine connected to the propeller and the shaft drives the propeller.

However, since the exhaust gas is generated during the operation of the diesel engine, a discharge pipe for discharging the exhaust gas to the outside of the hull must be formed.

In addition, when the cargo is transported to a ship, it usually takes more than a few months to cross the ocean.

Therefore, boarding passengers of the vessel should settle for accommodation in the ship for several months. In order to solve the problem, a generator for supplying electricity is required to solve the problem of the room and a discharge pipe for discharging the exhaust gas to the outside of the hull because the exhaust gas is generated during operation of the generator.

1 is a side view showing a stern portion of a conventional ship.

An engine room (10) is located below the stern section, and an upper deck (11) is located above the engine room (10). The residence (12) in which the ship 's boarders reside is located on the upper deck (11).

The residence port 12 has a total of six layers including a wheel house 13 which is located at the uppermost position and in which the traveling direction of the ship is controlled. The stern side partition wall of the cargo space 15 located at the rear end, Lt; / RTI >

A radar mast 14 for facilitating communication with the outside is located at an upper portion of the wheel house 13, and the radar mast 14 can be folded. This is to lower the height of the ship when it passes through a bridge or the like.

The engine compartment casing 16 is located on the aft side of the housing 12, and a variety of equipment such as a boiler and an exhaust device may be installed in the engine compartment casing 16.

A funnel casing 20 is disposed at an upper portion of the engine room casing 16 and is discharged from a power supply generator and a diesel engine (or steam turbine) located inside the engine room 10 of the ship at an upper portion of the funnel casing 20 A funnel 21 for discharging the exhaust gas to the outside of the hull is located. The funnel 21 is not vertically positioned but is inclined in the stern direction.

The reason why the funnel 21 is inclined in the stern direction is as follows. Firstly, the exhaust gas does not reach the residence 12 and the wheel house 13 as much as possible, thereby creating a pleasant living environment for the passengers, . Secondly, the height of the ship should be minimized so that the ship can easily pass through the bridge.

Conventionally, the funnel is disposed at the center of the upper part of the hull of the ship or slightly offset to the stern side. In this case, since the funnel is installed at a high height above the hull for smooth discharge of exhaust gas, There is a problem that the space utilization can not be reduced because it can not be stacked.

The exhaust gas injecting apparatus 300 injects exhaust gas, which is provided at an end of the funnel exhaust pipe 200 and discharged through the funnel exhaust pipe 200.

The exhaust gas injecting apparatus 300 is installed in the funnel exhaust pipe 200 and is installed between the space 400 and the funnel exhaust pipe 200 to be described later.

The exhaust gas injection device 300 blows the exhaust gas discharged through the funnel exhaust pipe 200 into the space part 400.

In addition, the exhaust gas injecting apparatus 300 has a function of preventing air or water from flowing back toward the funnel exhaust pipe 200.

The space portion 400 is connected to the exhaust gas injection device 300 and collects the exhaust gas injected into the exhaust gas injection device 300 through the funnel exhaust pipe 200.

A pressure sensor S is installed in the space 400 to sense the inflow and pressure of water flowing into the space 400 through the discharge port 500.

At this time, the pressure sensor S is electrically connected to the controller 700, and the controller 700 controls the signal sensed by the pressure sensor S.

A water tight opening / closing door 410 for preventing reverse flow is installed at the side of the space 400 in order to prevent the water flowing into the outlet 500 from flowing back to the air suction unit 600 through the outside air pipe 610 .

The water-tight opening / closing door 410 for blocking the backflow senses the amount and pressure of water flowing into the space 400 through the outlet 500 from the pressure sensor S, and when the quantity and pressure are high, The controller 700 receives the signal and closes the check valve 410 to prevent the water from flowing back to the outside air pipe 610.

The exhaust port 500 is installed on a side surface of the space portion 400 to exhaust the exhaust gas to the outside of the hull.

The discharge port (500) is installed outside the stern (100) and installed near the water surface.

Also, the outlet 500 is installed to be inclined downward so that the water can be discharged naturally smoothly even if water flows in.

That is, since the discharge port 500 is not parallel to the water surface and is inclined downward, when the water flows into the inside of the discharge port 500, water flowing into the discharge port 500 can be discharged to the outside.

The outlet (500) is provided with a pressure sensor (S) for sensing inflow and pressure of water.

A watertight opening / closing door 510 is installed between the discharge port 500 and the space 400 in accordance with the inflow of the water sensed by the pressure sensor S and the pressure.

The watertight opening and closing door 510 senses the amount and pressure of the water flowing into the discharge port 500 from the pressure sensor S when the amount and pressure of the water flowing into the discharge port 500 becomes high, (S), and closes the watertight opening / closing door (510).

The air sucking and blowing device 600 is connected to the space part 400 and the outside air pipe 610.

The air sucking and blowing device 600 is connected to the space part 400 and controls the air sucking and blowing device 600 so that the exhaust gas flowing into the space part 400 can be discharged to the discharge port 500 under the control of the controller 700. [ (400).

At this time, according to the control of the controller 700, the watertight door 410 for preventing the backflow is opened and the air sucking and blowing device 600 is operated and the outside air flows into the space part 400 through the outside air pipe 610 Respectively.

As described above, the air suction and air blowing device 600 can keep the state where the exhaust gas is being compressed in the space part 400 when the discharge port 500 is long filled with water, 600 are operated to introduce air into the space portion 400.

That is, when the watertight opening / closing door 510 is opened for a predetermined time or more, the air sucking and blowing device 600 is actuated to quickly send the outside air to the space portion 400 to increase the pressure, 500).

According to another aspect of the present invention, a funnel device for discharging the exhaust gas generated in the engine 110 is installed outside the stern 100 in parallel with the water surface, and prevents backflow of air and water toward the funnel exhaust pipe 200 It is possible to smoothly discharge the exhaust gas, thereby maximizing the container loading space on the ship and increasing the amount of shipment. Also, the ship having a stern funnel device for securing additional container bay to prevent the exhaust gas from entering the hull .

That is, a funnel device is installed outside the lower part of the stern 100, and a funnel exhaust pipe 200 is connected to the main exhaust pipe 120, and the exhaust gas injected into the funnel exhaust pipe 200 is collected A water tight opening and closing door 410 for preventing backflow and a watertight opening and closing door 410 for preventing reverse flow are provided in the space part 400 and the discharge opening 500, respectively, while a space part 400 is provided in the space part 400, (510) is installed to block the inflow of water according to the detection of the pressure sensor (S), air is sucked into the space part (400) by the air suction and air blowing device (600) It is possible to apply the present invention to all ships where the crew can live comfortably because the exhaust gas does not flow into the inside.

The operating state of the stern funnel device for securing the container bay according to the present invention having the above-described structure will be described below.

The watertight opening and closing door 510 is opened and the watertight opening and closing door 410 for blocking the backflow is closed so that the exhaust gas generated in the engine 110 flows through the main exhaust pipe 120, Is introduced into the exhaust pipe 200 and discharged to the discharge port 500 through the exhaust gas injection device 300 and the space part 400 to be discharged to the outside of the hull.

Since water is not introduced into the discharge port 500, no pressure is generated in the discharge port 500, so that the exhaust gas flows into the exhaust gas injection device 300 and the space part 400, 500, respectively.

When water is introduced into the discharge port 500, the pressure sensor S installed in the discharge port 500 senses the inflow of water and receives a signal from the controller 700 to close the watertight door 510 .

At this time, even when the watertight door 510 is closed, the exhaust gas is continuously introduced into the space portion 400 through the exhaust gas injection device 300, and the exhaust gas is compressed into the space portion 400.

In addition, since the outlet 500 is inclined downward when the watertight opening / closing door 510 is closed when a predetermined time has elapsed, the water introduced into the outlet 500 is naturally re- The watertight opening and closing door 510 opens according to the control of the controller 700 and the exhaust gas compressed in the space portion 400 is normally discharged through the discharge port 500. [

Meanwhile, when the water in the discharge port 500 is locked, the pressure sensor S installed at the discharge port 500 detects the inflow of water, and the watertight door 510 is closed under the control of the controller 700, The exhaust gas flowing out of the funnel exhaust pipe 200 in a state where the opening / closing door 510 is closed is continuously discharged to the space portion 400 through the exhaust gas injecting device 300.

If the outlet 500 is full of water even after a certain period of time, the pressure of the space portion 400 is increased to push the exhaust gas.

The watertight opening / closing door 410 for preventing backflow is opened when the watertight opening / closing door 510 is closed, and the outside air is strongly introduced into the space part 400 according to the operation of the air suction and air blowing device 600.

At this time, as the external air is introduced into the space part 400 by the operation of the air suction and blower device 600, the pressure in the space part 400 increases.

When the pressure in the space part 400 increases, the pressure sensor S installed in the space part 400 senses the pressure in the space part 400 and the pressure sensor S installed in the discharge port 500 When the pressure in the discharge port 500 is sensed, the controller 700 controls the signals sensed by the respective pressure sensors S and compares the pressure in the space part 400 with the pressure in the discharge port 500, The watertight opening / closing door 510 is opened.

As the watertight opening / closing door 510 is opened, the exhaust gas is pushed toward the discharge port 500 by the pressure in the space portion 400 and discharged to the outside of the hull.

When the exhaust gas is discharged through the outlet 500 after a predetermined time, the watertight door 410 for blocking the backflow is closed to block the inflow of the outside air.

At the same time, when the pressure in the space portion 400 and the pressure difference in the discharge port 500 are removed, water can be introduced into the discharge port 500 again.

In this case, as described above, the pressure sensor S provided at the discharge port 500 senses the inflow of water, closes the watertight door 510 again and opens the watertight door 410 for preventing the reverse flow to operate the air suction and blower 600 When the pressure in the space portion 400 becomes higher than the pressure in the discharge port 500, the watertight opening / closing door 510 is opened to discharge the exhaust gas to the discharge port 500 at a high pressure .

On the other hand, if water is not introduced again into the discharge port 500, the watertight opening and closing door 510 is operated normally as it is opened without being closed.

As described above, the present invention is not limited to the above-described specific preferred embodiments, and any person skilled in the art can make various modifications without departing from the gist of the present invention. It is to be understood that such changes and modifications are intended to fall within the scope of the appended claims.
