Description

Step-by-step management and growth rate prediction management system for vessel fouling organisms through the removal of small and medium-sized vessel fouling organisms and artificial intelligence technology {ACTIVE ANTI-FOULING SYSTEMS AND PROCESSES FOR MARINE VESSELS}

The present invention is optimized for small and medium-sized ships and builds an independent power source other than the engine to continuously remove ship fouling organisms and manage status information of anti-fouling equipment, and to manage ship fouling organisms step by step and predict their growth rate through artificial intelligence technology. It's about the system.

And it relates to a ship anti-fouling device that removes fouling from ship parts through an ultrasonic system using a renewable energy source. More specifically, it generates ultrasonic waves on the surface of the hull to prevent marine life from entering the hull. It relates to a ship anti-fouling device (corresponding to an anti-fouling device) that prevents adhesion to the ship.

In general, a portion of the hull of a ship, offshore structure, yacht, or floating hull structure may be submerged in seawater. The sea is rich in nutrients, and the area below the surface of the hull floating in the sea is filled with unknown clams, seaweed, and hard substances.

Numerous lumps that have hardened and turned into stones can become conditions for vegetation.

Organic substances attached to the body of the ship below sea level are called hull contaminants, or fouling. Therefore, in the case of hulls used in the sea, it is necessary to suppress the generation of fouling and protect the hull skin below the water surface.

A protective layer can be provided for.

Fouling and adhesion of marine life to the ship's hull can increase ship resistance, thereby reducing planned ship operating performance (e.g. speed or power) and resulting in excessive additional expenditure on fuel costs.

In an effort to combat anti-fouling, paint companies are developing new anti-fouling paints such as copper-based anti-fouling paints and silicone paints.

Additionally, from a ship management perspective, underwater vessel cleaning and management operations may also be fouling removal and deterrence efforts.

According to the prior art, there are cases where an antifouling system using ultrasonic waves was applied to personal yachts and small ships.

The ultrasonic device of the prior art may be a device that can be placed under the water by separate personnel while loaded on a personal yacht or small ship, or can be lifted and stored after use.

However, in terms of production economy and maintenance costs, the ultrasonic devices of the prior art are so expensive that they cannot actually be applied to large merchant ships, and it is very difficult to cover the entire area of large merchant ships.

In other words, in the case of small ships, a spherical and expensive ultrasonic generator device is used after inserting it near the hull below the sea level, so it can cover large ships with a larger outer hull surface area than small ships, and is also economical. There is an urgent need to develop technology that can demonstrate satisfactory anti-fouling effects.

And registration number 10-2414515 is that since the paint color of marine life and ships is usually different, the color of the paint changes over time. A color sensor that reacts to this color change is attached, and the color sensor detects and sends an alarm. When displayed, it provides an alarm system and method for monitoring marine life on ships that allows managers to access remotely through monitoring in the office and check the marine life adhesion status in real time through cameras.

The problem with the prior art is that images are collected by taking images of the bottom of the ship in an image processing system, and it is impossible to collect the images of the entire bottom of the ship.

In other words, it is impossible to install an image processing system on the entire bottom of the ship, and if the water depth is turbid, it is impossible to identify ship-attached plants.

After being equipped with a fuel level sensor (a100) that detects the ship's fuel consumption, a sailing distance measuring unit (a110) that measures the ship's operating distance, a control unit (a120), an operation processing unit, a monitoring unit (a130), and a communication unit, the fuel After sailing the ship with the tank (not shown) initially filled with fuel, the fuel level is detected through the fuel level sensor (a100) linked to the fuel tank, and the operating distance is measured through the operating distance measuring unit (a110). The fuel consumption is measured for the sailing distance, and if the measured value of fuel consumption meets the set standard value, the sailing ship is judged to have current and friction resistance corresponding to the set value, and it is determined that no ship-attached plants are attached to the bottom of the ship.

After sailing the ship with the fuel tank initially filled with fuel, the fuel level is detected through the fuel level sensor (a100) linked to the fuel tank, the navigation distance is measured through the navigation distance measuring unit (a110), and then sailed. Fuel consumption is measured for distance, and if the measured value of fuel consumption is greater than the set value, the sailing ship is judged to have current and friction resistance greater than the set value, and it is determined that ship-attached plants are attached to the bottom of the ship. This is a configuration that communicates to the administrator through a communication network.

Furthermore, if it is determined as above that a ship-attached plant is attached to the bottom of the ship, the ultrasonic generator is operated through the control unit.

The present invention is optimized for small and medium-sized ships and builds an independent power source other than the engine to continuously remove marine organisms and manage status information of anti-fouling equipment, and to manage marine organisms by stage and predict their growth rate through artificial intelligence technology. It's about the system.

The purpose is to provide a ship anti-fouling device to prevent marine life from attaching to the hull by generating ultrasonic waves on the surface of the hull.

Another problem that the present invention aims to solve is to provide a ship anti-fouling device that can easily install an ultrasonic generator for antifouling on the surface of the hull and install the ultrasonic generator in parts of the hull where marine life is likely to attach. It's in what it provides.

The ultrasonic generator 110 generates ultrasonic waves in a horizontal direction parallel to the surface of the hull 11 through the ultrasonic tips 111 and 112 provided on both sides of the lower part to prevent marine organisms from attaching to the surface of the hull 11. .

That is, the ultrasonic waves generated by the ultrasonic generator 110 create vibrations in the water, and this vibration prevents marine organisms such as barnacles from attaching to the surface of the hull 11.

The body portion 120 supports the ultrasonic generator 110 at its lower side.

The body portion 120 may be provided to guide the ultrasonic generator 110 to an anti-fouling position where marine life is expected to attach to the hull 11.

In one embodiment, the body portion 120 may be made of body guides 121 and 122 combined in a telescopic structure.

The ultrasonic generator 110 may be fixed to the body guide 122 on the distal side.

In the illustration, the body portion 120 consists of a first body guide 121 and a second body guide 122 inserted into the first body guide 121.

In the illustrated embodiment, the body 120 consists of two body guides 121 and 122, but the number of body guides may vary depending on the size of the ship 10 or marine environmental conditions.

Guide grooves (not shown) are formed on both side surfaces of the body guides 121 and 122 in the vertical direction.

Guide protrusions (not shown) formed on both side ends of the second body guide 122 are coupled to the guide groove of the first body guide 121 and are installed to be movable within the guide groove.

The body portion 120 may be designed so that the ultrasonic generator 110 is located at the target antifouling point with the body guides 121 and 122 extending downward.

The ultrasonic generator 110 is installed at the distal end of the body 120, that is, the second body guide 122.

The ultrasonic generator 110 generates ultrasonic waves to prevent marine life from attaching to the hull.

The ultrasonic generator 110 is connected to the wire 161.

The wire 161 may be provided to lift the ultrasonic generator 110 for repair when a problem occurs in the ultrasonic generator 110.

Alternatively, it is also possible to lift the ultrasonic generator 110 by connecting the wire 161 to the distal end of the body 120.

The ultrasonic generator 110 can receive power through the power cable 162. The power cable 162 can receive power through a power supply provided on the quay wall side and supply power to the ultrasonic generator 110.

The body portion 120 has body guides 121 and 122 of a telescopic structure spread downward and extend long downward.

Accordingly, the ultrasonic generator 110 may be placed near an anti-fouling area on the surface of the hull 11 where marine life is likely to attach.

Although not shown, the body portion 120 may be provided to be folded or unfolded by a driving means such as a hoist.

The hoist may be provided to, for example, unfold the body 120 by unwinding the wire and fold the body 120 by winding the wire.

The floating body 130 can be installed on the body 120 to float the body 120 on the sea.

In the city, the floating body 130 consists of a cylindrical floating plate,

Therefore, according to this embodiment, the ultrasonic tips 111 and 112 of the ultrasonic generator 110 are positioned by the floating body 130 at a depth where marine life is easily attached to the sea surface.

The support portion 220 is provided to support the body portion 120 to the hull 11.

In one embodiment, one end of the support part 140 is connected to the body part 120, and the other end is fixed to the hull in a vacuum manner, so that it can be provided as a vacuum shaft for fixing the body part 120 to the hull 11. .

In this embodiment, the ship anti-fouling device 100 can be easily installed by the operator pressing and attaching the vacuum shaft to the hull.

In addition, the ultrasonic generator 110 can be installed on the outer surface of the hull while preventing damage to the coating film installed on the hull surface, and the ship anti-fouling device 100 can be easily removed when the ship is in operation.

In addition, the support rod 141 is installed so that the movement of the end side is flexible in the up and down direction, so that it can respond to changes in sea level due to waves or tidal differences.

Figure 2 is a diagram showing a plurality of ship anti-fouling devices 100 installed on the hull according to an embodiment of the present invention. Referring to FIG. 2, a plurality of ship anti-fouling devices 100 may be installed at regular intervals on the hull.

In the ship anti-fouling device 100 according to an embodiment of the present invention, the ultrasonic generator device 110 can be easily installed or removed from the surface of the hull 11 on the deck of the ship.

Therefore, in cases where marine life is likely to attach to the surface of the hull, such as when the ship is anchored, the ship anti-fouling device 100 can be easily installed on the quay wall to the side of the hull to prevent fouling, and the marine life can be easily installed on the side of the ship, such as when the ship is sailing. In cases where there is little possibility of organisms attaching to the hull, the ship's operating efficiency can be increased by removing the ship anti-fouling device 100 to prevent an increase in frictional resistance caused by the ship anti-fouling device.

A motor (not shown) is provided inside the second body guide 122 and the rotation axis of the motor is a vertical stand 230 that supports the propeller motor 210 perpendicularly to the lower end of the second body guide 122. (not shown), the lower end of the vertical stand 230 supports the propeller motor 210, and the propeller 200 is connected to the rotation axis of the propeller motor 210, with an ultrasonic generator 110 in front of the propeller. ) is configured to be located,

Simultaneously with the operation of the ultrasonic generator 110, the propeller 200 is rotated by the propeller motor 210 to move the ultrasonic waves generated from the ultrasonic generator 110 far away.

When the rotation speed of the propeller motor 210 is varied, the ultrasonic wave moving distance is varied, so that the ultrasonic wave can be moved throughout the longitudinal direction of the hull 11.

In general, the ultrasonic travel distance is 20 to 30 meters, but to send it over a longer distance, an expensive ultrasonic device must be used, making it uneconomical.

However, the present invention can travel farther than 30 meters through a propeller.

When the vertical stand 230 is rotated by a connected motor (not shown), the center of the circumference of the vertical stand 230 becomes a rotation axis and rotates to form a propeller motor 210,

There is an advantage that the propeller 200 and the ultrasonic generator 110 can generate ultrasonic waves throughout the front and rear sides of the hull while rotating.

The power of the ship anti-fouling device 100 of the present invention is generated from renewable energy sources by using electric power generated from solar power generation and wind power generation.
