Fuel supply device {FUEL SUPPLY DEVICE}

The present invention relates to a fuel supply device, and more particularly, to a fuel tube provided to a crane in a port; an injection part formed at one end of the fuel tube; a fuel injection unit formed on one side of the deck of the unmanned surface boat, while receiving the injection unit; and a fuel tank in which fuel is stored, wherein the injection unit is accommodated inside the fuel input unit to supply fuel so that a crew member does not need to board the unmanned surface boat to connect the fuel supply unit, and the fuel supply unit It is an invention to increase the efficiency of work and prevent injuries to crew members by combining them collectively.

As ship unmanned technology develops, it can be used for various military operations such as anti-submarine warfare, anti-mine warfare, surveillance, reconnaissance, maritime information investigation, and information operation. The development of unmanned surface vehicles is actively progressing to carry out the field.

The unmanned surface boat has an engine for operation in the sea, and fuel for driving this engine is stored and used.

Since the unmanned surface boat is operated unmanned, a crew member moves and mounts it directly from the port or mother ship to connect the supply device for fuel supply.

In addition, unmanned surface craft for navigating fast and narrow areas are small in size and cannot store a lot of fuel, so frequent fuel supply is required.

For this reason, there are frequent cases in which the crew members board the unmanned surface craft and connect a device for supplying fuel.

Due to the characteristics of unmanned surface boats operated in the ocean, an accident in which a crew member falls due to being shaken by waves occurs, or it is difficult to connect a fuel supply device to unmanned surface boats due to wind and reefs.

These problems reduce work efficiency and cause injuries to crew members, resulting in safety problems.

Therefore, there is a need for a fuel supply device capable of connecting the fuel supply devices collectively at a port or mother ship without the need for crew members to board the unmanned surface craft.

The fuel supply device according to the present invention is a device for supplying fuel to an unmanned surface boat 20 in a port 10 or a mother ship, and the unmanned surface boat 20 described in the present invention is unmanned through a mounted engine and remote control. It is possible to operate, and preferably includes an electronic module for remote control, a control circuit, and various sensor devices.

In addition, it is preferable that the mother ship carries the unmanned watercraft 20 and carries out the work by launching the unmanned watercraft 20 when necessary, and recovers and operates the unmanned watercraft 20 again after the work is finished. Do.

A fuel supply device according to the present invention includes a crane 100, a fuel input unit 200 and a fuel tank 30.

First, referring to FIGS. 1 and 2, a fuel tube 110 through which fuel moves along the crane 100 installed in the harbor 10 is formed, and the fuel tube 110 is preferably a flexible material such as rubber, It is not limited to the material, and various materials may be used. Here, the crane 100 installed in the port 10 may be installed on a mother ship that carries and moves the unmanned watercraft 20.

One end of the fuel tube 110 is formed with a disc-shaped injection unit 120 through which fuel is discharged. Here, the injection part 120 is preferably a metal material having ferromagnetism.

Next, a fuel injection unit 200 is formed on one surface of the deck of the unmanned watercraft 20 and is formed in a shape inserted into the inside of the deck from one surface of the deck.

Referring to FIG. 2 , the injection unit 120 is accommodated into the fuel input unit 200 to supply fuel.

Referring to FIG. 3 to describe the fuel input unit 200 , the fuel input unit 200 includes an opening/closing unit 210 , an inlet unit 220 and a flow pipe 230 .

First, the opening/closing unit 210 is formed on the upper side of the fuel input unit 200 and serves as a lid for the fuel input unit 200 .

In addition, the opening/closing unit 210 is formed to be openable to receive the injection unit 120, and the opening/closing unit 210 includes a pair of opening/closing doors 211 and hinges 212.

Assuming that there is a center line crossing the center of the opening and closing unit 210, the pair of opening and closing doors 211 are formed to be opened and closed respectively based on the center line, so that they can be opened and closed in both sides.

For this reason, when the injection unit 120 is accommodated in the fuel input unit 200, a pair of opening and closing doors 211 can be opened and closed, respectively, depending on the position where the injection unit 120 is accommodated.

Due to the feature that each of the opening and closing doors 211 can be opened and closed, since the injection part 120 is opened only at the location where the opening and closing part 210 is accommodated, the entire opening and closing part 210 is not opened, so that sea water flows in, causing internal corrosion and a large amount of sea water flowing into the fuel tank. It has the effect of significantly reducing what can be.

The hinge 212 is formed across the center of the opening and closing unit 210 so that the pair of opening and closing doors 211 can be moved in an opening and closing structure on both sides based on the center line of the opening and closing unit 210 .

A plurality of inlets 220 are formed inside the fuel inlet 200, and the inlet 120 abuts and is connected to supply fuel.

Here, the shape of the inlet part 220 is formed to correspond to the shape of the injection part 120, and it is preferable that the diameter of the inlet part 220 and the injection part 120 be the same.

Referring to FIGS. 5 to 7 , the inlet portion 220 includes a magnetic portion 221 having magnetism and an inlet opening/closing portion 222 .

In detail, the magnetic part 221 is formed on the outer surface of the inlet part 220 and comes into contact with the injection part 120 with magnetic force.

Due to this, the injection part 120 and the inlet part 220 come into contact with each other by magnetic force and are fixed. Since the injection part 120 and the inlet part 220 come into contact with each other by magnetic force, there is no need for a separate fastening member for fastening, thereby reducing costs.

In addition, since the injection part 120 and the inlet part 220 come into contact with each other with strong magnetic force, the fixing force increases.

In addition, since the injection part 120 and the inlet part 220 come into contact with each other by magnetic force, there is no need for a crew member to board the unmanned watercraft 20, thereby preventing the unmanned watercraft 20 from overturning and falling due to air volume. This has an increasing effect. A detailed description will be given later.

Next, referring to the inlet opening/closing portion 222, the inlet opening/closing portion 222 accepts the fuel discharged from the inlet portion 120 when the inlet portion 220 and the inlet portion 220 come into contact with each other and are fixed by magnetic force. open for

In detail, the inlet opening 222 is maintained in a closed state until the inlet 120 and the inlet 220 come into contact with each other and are connected by magnetic force. There is an effect of increasing durability by preventing possible seawater and various contaminants from entering the internal fuel tank 30 to prevent failure of the unmanned floating boat 20.

In addition, when the injection part 120 and the inlet part 220 come into contact with each other and are fixed, the inlet opening/closing part 222 is opened to accommodate the fuel discharged from the injecting part 120, so that the fuel passes through a flow path to be described later ( 230) so that it can be stored in the fuel tank 30.

When a predetermined amount of fuel is stored in the fuel tank 30, the inlet opening 222 is closed again, and when the connection between the inlet 120 and the inlet 220 is released, seawater and contaminants that may be introduced has the effect of preventing the inflow of

The flow pipe 230 will be described with reference to FIGS. 2 and 3 .

The flow pipe 230 is formed by extending from the plurality of inlets 220 and is formed in a pipe shape through which fuel flows, so that the fuel moves along the flow pipe 230 and moves along the flow pipe 230. Fuel is received and stored in the fuel tank 30 .

The flow pipe 230 is branched according to the configuration of the plurality of inlets 220 and is formed into a plurality of pieces, but even if fuel flows into any one of the plurality of flow pipes 230, the fuel is moved and the same The plurality of flow pipe 230 branched so that the fuel can be accommodated in the fuel tank 30 is formed as a single flow pipe 230 as it gets closer to the fuel tank 30 .

As a result, fuel can be stored in the fuel tank 30 even when fuel is accommodated in any one of the plurality of flow pipes 230 . A detailed description will be given later.

Hereinafter, the operation method and effect of the fuel supply device according to the present invention will be described in detail.

First, referring to FIGS. 1 and 2, the fuel tube 110 and the injection part 120 provided in the crane 100 of the harbor 10 are formed in the unmanned watercraft 20 using the crane 100 It is located near the fuel input unit 200.

Thereafter, when the fuel tube 110 and the injector 120 are brought close to the opening and closing part of the fuel input unit 200 using the crane 100, the opening and closing door 211 of the opening and closing unit is formed across the center of the opening and closing unit Hinge 212 is opened to the inside of the fuel input unit 200, and the injection unit 120 and the fuel tube 110 are accommodated inside the fuel input unit 200.

Here, referring to FIG. 4 , the injection part 120 comes into contact with magnetic force due to the magnetic part 221 of the inlet part 220 formed in plurality inside the fuel injection part 200 .

At this time, the injection unit 120 can supply fuel when it comes into contact with and is connected to any one of the plurality of inlet units 220 by magnetic force (see FIG. 2 ).

Here, the reason why the inlet 220 is composed of a plurality is to supply fuel unmanned without a crew member boarding the unmanned surface boat 20, and among the inlet 120 and the plurality of inlets 220 The connection between the injection part 120 and the inlet part 220 is handled collectively by allowing it to come into contact with any one inlet part 220 and be fixed, thereby supplying fuel to the unmanned surface boat 20 by the crew This is to prevent the crew member from falling and being injured in the unmanned surface boat (20) by omitting the boarding process for the purpose.

In addition, since the inlet portion 220 is composed of a plurality of pieces, the probability of injecting fuel by contacting the injection portion 120 is increased, thereby facilitating the supply of fuel.

Therefore, when the injection unit 120 is simply accommodated inside the fuel input unit 200, since it can be fixed in contact with the inlet unit 220 by its own force, the fastening work is easy and the work efficiency is increased. there is.

In addition, even if the injection part 120 and the inlet part 220 do not come into contact with each other and are located, simply by operating the crane 100 to move the injection hole inside the fuel input part 200, one of the plurality of inlet parts 220 It is possible to supply fuel by being connected to one of the inlets 220 by magnetic force.

Next, referring to FIGS. 5 to 7 , when the injection part 120 and the inlet part 220 come into contact with each other by magnetic force, the inlet opening and closing part 222 of the inlet part 220 is opened, as shown in FIG. 2 . The fuel is stored in the fuel tank 30 along the fuel pipe.

At this time, the inlet opening/closing part 222 operates only when the inlet part 220 and the injection part 120 are correctly fastened, and the fuel counts in the gap that may occur between the incorrect inlet part 220 and the injection part 120. It has the effect of preventing contamination.

In addition, it is opened only when fuel is input to prevent the inflow of sea water or contaminants into the fuel tank 30, thereby preventing corrosion and contamination of the fuel.

Here, a control unit (not shown) for controlling the opening and closing of the inlet opening and closing unit 222 may be included, and the opening and closing of the inlet opening and closing unit 222 may be controlled depending on whether or not the inlet unit 220 and the injection unit 120 are fastened. there is.

In addition, since the fuel input unit 200 is frequently exposed to sea water, a coating layer is formed on the surface of the fuel input unit 200 to prevent corrosion and contamination by sea water.

The coating layer (not shown) is coated using a coating composition, and the coating layer using the coating composition may exhibit an anti-corrosion effect. Specifically, a coating layer is formed on the surface of the fuel inlet 200 by the coating layer to prevent the fuel inlet from being exposed to the outside, and contains metal having a higher ionization tendency than the fuel inlet to prevent corrosion of the fuel inlet. can

More specifically, the coating composition of the present invention is a siloxane-based compound represented by Formula 1; organic solvents, metal compounds and amine compounds;

[Formula 1]

Here, n is an integer from 1 to 100.

When a coating layer is formed on the surface of the fuel inlet using the coating composition of the present invention, the adhesion to the fuel inlet is excellent, the coating layer is not easily peeled off by external force, and a metal compound having a higher ionization tendency than the fuel inlet is included. Accordingly, an excellent anti-corrosion effect can be exhibited.

Specifically, since the siloxane-based compound contains a mercapto group as a substituent, it exhibits excellent adhesion to the fuel inlet and maintains the viscosity of the coating composition at a certain level to increase formability and stability.

The metal compound serves as an erosion and corrosion inhibitor that blocks contact with moisture, salt or oxygen. Here, as the metal compound, a metal having a higher ionization tendency than iron may be used to act as an erosion and corrosion inhibitor. That is, metals or alloys such as aluminum (Al), magnesium (Mg), and zinc (Zn) may be used, and zinc (Zn) is mainly used.

A particle size of the metal compound may be 0.1 to 10 μm. If the particle size of the metal compound is 0.1 μm or more, the manufacturing cost of the metal compound can be reduced, and if the particle size of the metal compound is 10 μm or less, the metal particles can be uniformly dispersed.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited to the above examples.

The amine compound may include a modified aliphatic amine or tertiary amines, and specifically, trimethylamine or aniline may be used. The amine compound may be included in the coating composition to prevent cracking or peeling of the coating film. That is, the effect of preventing cracks or peeling of the coating film due to use by increasing the adhesive strength of the coating layer is excellent.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, and the like, but is not limited to the above examples and may be used without limitation.

For forming the coating layer, the coating composition is more specifically a siloxane-based compound represented by Formula 1; organic solvents, metal compounds and amine compounds.

The coating composition may include 40 to 60 parts by weight of the siloxane-based compound represented by Formula 1, 20 to 40 parts by weight of a metal compound, and 5 to 15 parts by weight of an amine compound, based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component is of critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost nonexistent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when applied to the surface of the fuel input unit 200, there is a problem that it is not easy to form a coating layer because it flows down, and the coating composition exceeds 1800 cP. In this case, there is a problem in that it is not easy to form a uniform coating layer.

[Preparation Example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with a siloxane-based compound represented by Formula 1, zinc, and trimethylamine:

[Formula 1]

Here, n is an integer from 1 to 100.

A more specific composition of the coating composition is shown in Table 1 below.

(unit weight parts)

2. Preparation of coating layer

Typically, the experiment was conducted using aluminum, which is a metal material that easily corrodes, instead of the material of the fuel input unit 200.

After applying the coating composition of DX1 to DX5 on one surface of aluminum of 10 × 10 cm, the coating layer was formed by curing.

Experimental Example

1. Evaluation of surface appearance

Due to the difference in viscosity of the coating composition, after preparing the coating layer, a sensory evaluation was conducted on whether a uniform surface was formed. Evaluation was conducted on whether or not a uniform coating layer was formed, and the evaluation was conducted according to the following criteria.

○: uniform coating layer formation

×: Formation of non-uniform coating layer

TX1 TX2 TX3 TX4 TX5 sensory evaluation × ○ ○ ○ ×

When forming the coating layer, when the viscosity is less than a certain amount, flow occurs on the surface of the fuel inlet, and it is difficult to form a uniform coating layer after the curing process in many cases. Accordingly, a problem of lowering the production yield may occur. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition and it is impossible to form a uniform coating layer.

2. Measurement of corrosion properties

In order to confirm the corrosion characteristics, a corrosion resistance test was conducted using an aluminum plate without a coating layer as a control and an aluminum plate with a coating layer of TX1 to TX5.

The aluminum plate was immersed in a beaker containing 10% by weight of CuCl2 aqueous solution, and the degree of corrosion was checked over time.

If the generation of hydrogen gas is confirmed with the naked eye, it will be said to mean that corrosion has occurred, and it was confirmed whether or not corrosion occurred until 24 hours had elapsed.

○: Corrosion occurs

×: no corrosion

TX1 TX2 TX3 TX4 TX5 control group corrosion occurs ○ × × × × ○

As a result of the experiment, it was confirmed that hydrogen gas was generated shortly after the aluminum plate, which was a control group, was placed in a beaker, and copper was precipitated in less than 1 hour. In the case of TX1, hydrogen gas was generated after 3 hours, and copper precipitation was confirmed after 6 hours.

In the case of other coating layers, corrosion did not occur even after 24 hours, and it was confirmed that there was an excellent effect in preventing corrosion.
