Abstract

PURPOSE: An automatic drainage system for a ship is provided to prevent flooding accident in a ship or a ship sinking accident in advance by automatically draining inflow water to the outside when a great quantity of rainwater or seawater is flowed into the bottom of the ship at unexpected time. CONSTITUTION: An automatic drainage system for a ship comprises a submerged pump(100) and a control device(210). The submerged pump is arranged at the bottom of a ship where flooding is expected, and comprises first to third water level sensors(111,112,113) having each different length. The control device supplies power to a second control unit(322) when inflow water flowed into the bottom of the ship and the first water level sensor are electrically electrified. If the electricity is disrupted, the control device cuts off the power supplied to the second control unit. If the first and second water level sensors are electrically electrified by the inflow water, the control device continuously supplies the power to the second control unit. The inflow water and the second and third water level sensors are electrically electrified, the second control unit supplies the power to a third control unit to operate a submerged pump by the third control unit, thereby draining the inflow water to the outside of the ship. The second control unit supplies the power to the third control unit until the inflow water and the second water level sensor are electrically disrupted. If the inflow water is electrically disrupted with the second water level sensor according to descending the water level of the inflow water, the second control unit cuts off the power supplied to the third control unit to stop operation of the submerged pump.

Description

Automatic Drainage System for Ships {AUTOMATIC DRAINAGE SYSTEM OF SHIP}

The present invention relates to an automatic drainage system for a ship for automatically draining the inflow water introduced into the bottom when a large amount of rainwater or seawater is introduced into the bottom of the small vessel such as a fishing boat or a yacht.

Small vessels defined in the present invention means a vessel of less than 50 tons, such as marine fishing vessels, fishing vessels or leisure yachts.

In addition, the first level sensor among the first to third level sensor defined in the present invention means that the position is located closest to the bottom surface of the bottom, the third level sensor is to prevent the flooding or sinking accident of the ship The sensor is installed at a critical water level, and the second water level sensor refers to a sensor located between the first and third water level sensors.

However, rainwater that can lead to flooding or sinking accidents, or the amount of water inflow and the water level depends on the spatial size of the bottom, such as the height and size of the vessel, so that the description of the installation position of the first to third level sensor is not described It will be, but if you have a basic knowledge of the vessel there will be no difficulty in installing the position of the first to third level sensor.

At present, small ships may be lifted to land and stored in a separate place when they are not sailing for a long time, but they are usually anchored at a ship's mooring, port or wharf. There is a problem that a large amount of sea water is introduced into the ship by the tsunami or rough waves.

In addition, since the ship generates excessive frictional heat in the joint portion of the shaft that transmits power to the screw during operation, seawater is introduced into the joint of the shaft to protect the shaft, thereby cooling the joint. Sea water may also flow into the bottom.

Therefore, the owner or crew frequently checks the inflow of the seawater flowing into the bottom of the ship during the operation of the ship or the vessel which has been anchored for a long time and, if necessary, pumps the inflow out of the ship by hand.

However, when an unexpected time, for example, at night or in the distance, a large amount of rainwater enters the bottom due to a heavy rain or a large amount of seawater enters the bottom due to heavy storms, There has been a problem that accidents that invade the ship or the ship sinks due to excessive inflow water sometimes occurs.

The present invention has been invented to solve the problem as described above, the object of the present invention by automatically draining the influent water even if a large amount of rainwater or seawater flows into the bottom of the small ship due to sudden heavy rain or coarse storm or tsunami The present invention provides an automatic drainage system for ships that can prevent ship flooding and sinking accidents and eliminate the hassle caused by the inflow of water.

Implementation means of the automatic drainage system for ships according to the present invention;

An underwater pump including first to third water level sensors having different lengths and disposed on the bottom of the submerged vessel;

When the inflow water introduced to the ship bottom and the first water level sensor are electrically energized, the power is supplied to the second control unit, and if the water supply is indirectly turned off, the power supplied to the second control unit is cut off, and the first to second water level detection is performed by the inflow water. When the sensor is energized, the power supplied to the second controller is continuously supplied. When the inflow water is electrically connected to the second water level sensor and the third water level sensor, the second controller supplies power to the third control unit to supply the third power. The control unit drives the submersible pump to drain the influent out of the vessel, but the second controller supplies power to the third controller until the influent and the second water level sensor are electrically disconnected, and the level of the influent is lowered. When the electrical connection with the second water level sensor is cut off, the second controller cuts off the power supplied to the third controller to stop the driving of the submersible pump. It can be implemented by a control control unit.

According to the present invention, when a large amount of rainwater or seawater flows into the bottom at an unexpected time, the inflow water is automatically drained to the outside to prevent flooding or fatal ship sinking in advance. Since there is no need to search or dig out, it is very convenient in terms of management of the ship.

Submersible pump 100 is not shown in the figure, but there is an impeller (not shown in the figure) that is rotated by a motor (not shown in the drawing) therein to suck water into the bottom of the pump when driving the motor outlet 101 To be discharged. The outlet 101 is connected to a connecting hose (not shown) extending out of the ship.

The submersible pump 100 has first to third water level sensors 111, 112, and 113 attached to its outer wall 102.

The first to third water level sensors 111, 112 and 113 are attached to the bracket 103 attached to the submersible pump 100 so that the height can be adjusted so that the height of each level sensor can be adjusted. The installation position of each sensor can be adjusted according to the height or size.

The first to third water level detection sensors 111, 112, and 113 may include first and third controllers of the control circuit device 210 (see FIG. 3) embedded in the control box 200 to be described later. It is electrically connected.

Therefore, the first to third controllers 321, 322 and 323 of the first to third water level detection sensors 111, 112, 113 and the electric circuit according to the presence or absence of energization between the inflow water are provided. Is delivered. This will be described in more detail below.

In FIG. 1, reference numeral 110 is a power line connected to the power line 204 (see FIG. 2) of the control box 200.

The control box 200 as shown in FIG. 2 is attached to a specific place of the ship, such as an engine room entrance or a steering room, and is attached to a specific place of the ship, and the first to third water level sensors 111 and 112 described above. It is electrically connected to the 113 and the submersible pump 100.

In the figure, reference numeral 205 is a power line connected to the power applied to the ship, 204 is a power line connected to the submersible pump 100, 202 is a main power switch, 203 is a display lamp that is turned on when the underwater pump is operated.

The first to third water level detection sensors 111, 112 and 113 are coated with an insulating material except for both ends.

The control circuit device 210 is built in the control box 200 as shown in FIG.

In FIG. 3, the control circuit device 210 includes first to third controllers 321, 322, and 323 that are circuitly connected to the first to third water level sensors 111, 112, and 113. Doing.

The first control unit 321 controls the on / off of the power supplied to the second control unit 322 in accordance with the electrical connection between the first water level sensor 11 and the influent.

For example, when the water level of the inflow water rises to a certain height on the bottom of the ship, the end of the first water level sensor 111 is energized with the inflow water, so that an electric circuit by energization is transmitted to the first control unit 321, thereby providing a first control unit. 321 is connected in a circuit so that power is supplied to the second control unit.

The second controller 322 is supplied with power to the third controller 323 when the third water level sensor 113 and the inflow water are electrically connected while the presence of power is controlled by the control circuit of the first controller 321. To control.

That is, when the water level of the influent flowing into the bottom rises to the position of the third level sensor 113, the second level sensor 112 and the third level sensor 113 are electrically connected by the inflow water, As a result, the second controller 322 forms a circuit to supply power to the third controller 323.

The third control unit 323 is electrically connected to the submersible pump 100 and the display lamp 203 so that the submersible pump 100 is driven by power supplied to the third control unit, and the display lamp 203 is turned on at the same time.

When the water level falls below the second water level sensor 112 by the driving of the water pump 100, the second control unit 322 shuts off the power supplied to the third control unit 323 and stops the water pump 100. At the same time, the display lamp 203 is also turned off.

As described above, the marine automatic drainage system according to the present invention repeatedly performs the operation of automatically draining the water pump while the water pump is driven according to the level of the inflow water introduced into the ship bottom.

That is, when rainwater or seawater continues to flow to the bottom while the inflow water introduced to the bottom by the submerged pump is drained, the level of the inflow water rises again to the third level sensor 113 as described above. The driving circuit of the submersible pump 100 and the display lamp 203 are turned on by the energization circuit of the detection sensor 113 and the first water level detection sensor 111 to drain water or seawater introduced into the vessel to the outside.

Reference numeral 401 of FIG. 4).

When rainwater or seawater is introduced into the vessel and the water level starts to rise, the first water level sensor 111 first detects the water level by the first water level sensor 111 (see reference numeral 402 of FIG. 4). The first control unit 321 forms a circuit to supply power to the second control unit 322 by the connection circuit with the influent (see reference numeral 402a of FIG. 4), and conversely, the first water level sensor 111 and the influent When the connection is blocked, the first control unit 321 cuts the power supplied to the second control unit 322 by circuit (see reference numeral 402b of FIG. 4).

On the other hand, when the level of the influent continues to rise so that the first level sensor 111 and the second level sensor 112 are disconnected from the electrical circuit by the influent, that is, the first level as shown in FIG. In the state in which the inflow water is located between the detection sensor 111 and the second water level detection sensor 112 (see reference numeral 4034 in FIG. 4), the second control unit 322 by energizing the first water level detection sensor 111 and the inflow water. ) Is maintained (see reference numeral 404 in FIG. 4).

If the water level reaches the third water level sensor 113, that is, the second and third water level sensors 112 and 113 are electrically energized with each other by the influent (see reference numeral 405 in FIG. 4), and the power is supplied thereto. By the circuit, the second control unit 322 forms a circuit so as to supply power to the third control unit 323 (see reference numeral 406 in FIG. 4).

The third controller 323 supplies the supplied power to the submersible pump 100 and the display lamp 203 to drive the submersible pump 100 to drain the inflow water to the outside, and at the same time, the display lamp 203 is turned on ( 4, reference numeral 407).

When the water level is lowered below the second water level sensor 112 while the drainage operation is performed by the driving of the water pump 100, that is, the third water level sensor 113 and the second water level sensor 112 are electrically connected. The second control unit 322 controls the third control unit 323 such that power is supplied to the submersible pump until disconnection (see reference numeral 408 of FIG. 4).

In FIG. 4, reference numeral 409 denotes a first level detecting unit 1 when the water level is located between the first level sensor 111 and the second level sensor 112 in a drainage work process in which influent is drained. Power is supplied to the second control unit 322 by the energizing circuit of the sensor 111 and the influent.
