Description

HALF SUBMERGED TYPE HULL REPAIRING APPARATUS [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-submerged hull repainting apparatus, and more particularly, to a semi-submerged hull repainting apparatus, in which a repainting operation is performed on a flooded area of a hull in a state where a painting surface is isolated from water, Submerged hull re-coating apparatus.

A hull is a structure that refers to a ship. The main hull has a frame or beam as a skeleton, and its outer surface has a box-like structure with an outer plate or a deck.

The shell and deck in the hull are located on the outer surface of the vessel and continuously receive the physico-chemical effects of the external environment such as rainwater, seawater, impacts by foreign bodies or objects, and the painting characteristics and conditions have a close relationship with the corrosion progress of the hull. Accordingly, it is necessary to continuously check the paint condition and periodically repaint the shell and deck.

In case of damage of painting surface in the non-immersion area of the hull, the non-immersion area is comparatively easy to repaint because the non-immersion area is a portion not exposed to water. However, when the paint is peeled off due to fender damage, The water repellency is difficult because the water is directly contacted when the coating surface damage occurs in the submergence area of the submerged area.

Background Art [0002] Conventionally, there is a coating apparatus using air pressure for a painting apparatus in a flood area. The painting device using air pressure is formed in a shape of a pistol combined with a handle case and a stirring case so that the epoxy and the curing agent are stirred inside the stirring case through the rotational force generated by the pressure of air introduced from the lower part of the handle case The brush is rotated and applied to the surface of the water immersion area to improve the water resistance and durability of the facility as well as to use it conveniently and safely in water and to apply it deeply and densely on the surface.

However, according to the conventional air pressure applying apparatus, only the moment when the flooded coating surface is coated is isolated from the water contact by the brush only, and as soon as the brush moves to another part, the painted coating comes into contact with water, There is a problem that a considerable amount of the paint is dissolved in water and disappears.

In addition, since the coating apparatus using the conventional air pressure is applied by the pressure of the paint which is applied in a state in which the painted part of the hull is wetted with water, the tackiness of the paint on the painting surface is inevitably reduced, There is a problem that re-peeling of the coated surface takes place in a short time in the portion where it is peeled off.

In addition, in the painting apparatus using the conventional air pressure, there is a problem that the swirling flow of water occurs around the painting apparatus by the brush rotating in the water, and the view of the worker submerged in the water is blurred and the working time is delayed. There has been a problem that it is difficult to confirm the visual field of the coated surface when the repainting operation is performed.

In addition, a conventional painting apparatus using air pressure has a problem in that a worker submerged in water is directly exposed to foreign substances adhering to painting surfaces or particles of paint floating in water, and a worker located in the water, It is difficult to secure the safety of the worker because the work is easily swept away in the direction away from the surface.

It is an object of the present invention to provide a method of re-coating a flooded area of a hull in a state where a painting surface is isolated from water, securing an operator's view on the painting surface even in a cloudy water, So that the worker can be isolated from foreign objects on the surface of the workpiece.

It is another object of the present invention to provide a semi-submerged hull re-coating apparatus which prevents an operator located in the water from swirling in a direction away from the painting surface due to the fluid force of waves even when the waves are hit.

The housing may include a transmissive portion through which light is transmitted so that the hull is observed from outside the housing.

A removable transparent film may be attached to the inner surface of the transmissive portion.

The glove includes: a first glove in which an operator's left hand is inserted; And a second glove into which the right hand of the operator is inserted. The housing is provided with a partition wall which forms a flow boundary of the worker floated on both the first glove and the second glove have.

The amphibious module may include: a pumping pump installed in the housing; A connection hose having an inlet connected to a discharge port of the amphibious pump; And a floating body coupled to the outlet side of the connecting hose.

A weight may be additionally provided at a lower portion of the housing to prevent conduction of the housing due to buoyancy.

A heater for heating the hull is installed in the housing and an exhaust port for discharging water vapor evaporated by the heater is formed on the housing.

According to the present invention, the housing is detachably attached to the hull along the periphery of the opening by the attaching / detaching means, whereby the re-coating of the hull is carried out in a state in which the painting surface is isolated from the water, It is possible to provide a semi-submerged hull re-coating apparatus in which a worker's view is secured against the coating material sprayed during the re-coating process and the worker is isolated from the foreign matter on the coating surface.

The submergence area of the hull (S) refers to the lower part of the water line which is the limit line where the hull (S) is immersed in water, and in a broad sense it is understood to include the part of the hull beyond the water line .

As shown in Figs. 1 and 2, the housing 110 is formed in a box shape having an opening on one side for isolating a painting part of the water immersion area of the hull from water.

The housing 110 is formed with a transmissive portion 112 through which light is transmitted so that an external worker can observe a painting region of the hull S. [ The transmissive portion 112 is formed of a transparent acrylic plate or a glass plate.

As shown in FIGS. 1 and 3, it is preferable that the transmissive portion 112 is formed over the entire surface of the housing 110 so that natural light from the outside flows into the interior of the housing 110 to secure a field of view.

Of course, since the operator performs the repainting operation while holding the glove 130 to be described later, the transparent portion 112 may be formed only on the upper portion of the glove 130 according to the eye level of the operator.

When the particles of the sprayed paint are floating and are buried in the permeable portion 112, it is difficult to observe the coated region through the permeable portion 112 .

As shown in FIG. 1, a removable transparent film FL is attached to the inner surface of the transmissive portion 112. The transparent film FL is attached to the inner surface of the transparent portion 112 before the painting operation. Particles of the paint sprayed during the painting operation are floated, but are buried in the transparent film FL instead of the transparent portion 112. The transparent film (FL) on which the paint is applied is removed after the painting operation and discarded.

One side of the housing 110, which is open, is detachably coupled to the hull (S). The opening of the housing 110 is provided with a detachment means 111 along the circumference thereof.

The frame F is formed of a hard synthetic resin and is bonded to the housing 110 by an industrial adhesive or bolt connection. A plurality of electromagnets M are provided inside the frame F and the frame F surrounds the electromagnet M to prevent water from flowing into the electromagnet M. [

2, the electromagnet M is installed toward the direction in which the housing 110 is opened in the frame F and has a magnetic line of force concentrated in the direction toward the hull S when power is applied. ). The electromagnet M forms a coupling force by the magnetic force with the hull (S) with the elastic member (111A) therebetween.

1 and 2, the elastic member 111A is configured to block the movement of water through the space between the magnetic portion 111B and the hull S. The elastic member 111A is a rectangular frame, And is coupled to a surface of the frame F facing the hull S.

The elastic member 111A is formed of a material such as rubber or silicone that can be easily expanded and contracted by an external force and is capable of moving between the magnetic portion 111B and the hull S when the electromagnet M is powered, (S), the gap between the frame (F) and the hull (S) is removed.

1 and 2, the painting means 120 includes a spray gun 121 and a flexible hose 122 as a structure for painting the hull S,

The spray gun 121 is configured to spray the paint, and various known spray guns 121 may be used. The spray gun 121 is supplied with paint through the flexible hose 122. Although not shown, a container containing a paint is connected to the spray gun 121.

The flexible hose 122 is configured to supply compressed air from the outside of the housing 110 to the spray gun 121. One end of the flexible hose 122 is connected to the spray gun 121 and the other end is connected to the hole formed in the housing 110 do.

Although not shown, the hull S is provided with an air pump, and the compressed air of the air pump communicates with the flexible hose 122 through the external hose. Of course, the air pump may be provided inside the housing 110.

1 to 3, the glove 130 is configured to operate the painting means 120 from the outside of the housing 110. The glove 130 is coupled to the housing 110 through a hole formed in the housing 110, do.

The glove 130 is formed of a material such as rubber or silicone that is elastically deformable and does not allow water to pass therethrough, and the rim of the end portion where the hand is fitted is coupled along the perimeter of the hole of the housing 110.

1 and 3, the glove 130 includes a first glove 131 to which the left hand is inserted and a second glove 132 to which the right hand is inserted. The operator has the first glove 131 and the second glove 132, Both hands are used to operate the painting means 120 in a state in which both hands are put on the second glove 132. [

1 to 3, the amphibious module 140 has a structure for discharging the water inside the housing 110 to the outside, and includes a water pump 141, a connection hose 142 and a floating body 143, .

A pumping pump 141 is provided inside the housing 110. Although not shown, the power source of the amphibious pump 141 is supplied from the hull S via a separate electric wire. The amniotic pump 141 may be of any known variety of positive amputation types.

2, the suction port 141A of the amphibious pump 141 is provided at the lower end of the housing 110 so as to completely discharge the water inside the housing 110. [ A hole for discharging water to the outside is formed in the housing 110 and a discharge port 141B of the pump 131 communicates with the outside through a hole formed in the housing 110.

There is a risk that the water outside the housing 110 flows into the housing 110 by the water pressure when the discharge port 141B of the amphibious pump 141 is immersed in water. The water discharged from the discharge port 141B of the amphibious pump 141 is discharged to the outside of the water surface through the connection hose 142 and the floating body 143. [

The connection hose 142 is extended to the outside of the housing 110 in a state in which the inlet communicates with the discharge port 141B of the amphibious pump 141. [

The floating body 143 is configured to float the outlet of the connection hose 142 out of the water surface, and is made of a material having a specific gravity smaller than that of water, such as an air tube or styrofoam. The lifting body 143 is coupled to the outlet side of the connecting hose 142 and the outlet of the connecting hose 142 is positioned above the water surface together with the floating body 143.

Conventionally, there is a painting apparatus using air pressure. However, as soon as the flooded painting surface is temporarily separated from the contact of water by the brush only when the painting is performed, As the paint comes into contact with water, there is a problem that a significant amount of the painted paint is dissolved in water and is lost.

In the semi-submerged hull repainting apparatus 100 of the present invention, when the lower portion of the housing 110 is immersed in water, the opening portion of the housing 110 is coupled to the hull S by the desorption means 111, The water inside the housing 110 is discharged using the amniotic fluid module 140 and then the diver outside the housing 110 hands the glove 130 and the inside of the housing 110 By operating the painting means 120, painting is performed in a state in which water contact with the painting area of the hull S is blocked, thereby solving the above-mentioned problems.

As shown in FIGS. 1 and 2, the weight 150 is provided below the housing 110 to prevent conduction of the housing 110 by buoyancy.

When the water in the housing 110 is discharged by the pumping module 140 in a state where the housing 110 is immersed in water, buoyancy of the housing 110 increases as the water is discharged, There is a risk of being released.

When the weight 150 is installed on the lower portion of the housing 110, a balance between the increased buoyancy and the load of the repainting apparatus 100 after the water in the housing 110 is discharged by the pumping module 140, The conduction of the housing 110 is prevented during the repainting operation.

As shown in FIG. 2, the weight 150 includes a fixed weight 151 and a detachable weight 152.

The fixed weight 151 is made of a material having a high density and is fixedly coupled to the lower end of the housing 110. When the fixed weight 151 is coupled to the lower end of the housing 110, the load of the fixed weight 151 prevents the housing 110 from being conducted during the repainting operation, Breakage of the housing 110 against impact is prevented.

The detaching weight 152 is detachably coupled to the lower end of the fixing weight 151 to adjust the total weight of the weight 150 in accordance with the buoyancy of the housing 110 depending on the depth of immersion in the water. Although not shown in detail, the fixed weight 151 is formed at its lower end with a threaded portion to which the weight 152 is screwed.

The desorption weight 152 is selectively coupled according to the depth at which the housing 110 is immersed in water. That is, when the housing 110 is deeply immersed in water, the buoyant force is formed to a volume that is submerged in water, so that a larger number of the desorption weights 152 are coupled than when the housing 110 is submerged in shallow water.

The desorption weight 152 also serves as a bridge for storing the hull repainting apparatus 100 in a state where the hull repainting apparatus 100 is placed on the bottom surface of the storage warehouse when the hull repainting apparatus 100 is stored.

As shown in FIG. 2, a heater 170 for applying heat to the hull S may be installed inside the housing 110.

The heater 170 is provided as an underwater electric heater, and is formed in a square frame shape and is coupled to the inner side surface of the opening of the housing 110.

The heater 170 couples the opening of the housing 110 to the hull S so that the inside of the housing 110 is isolated from the outside and the water inside the housing 110 is discharged using the amphibious module 140 And the heat is released. Although not shown, the power source of the heater 170 is supplied from the hull S via a separate electric wire.

The heater 170 generates heat for a certain period of time after the water in the housing 110 is drained from the housing 110 to complete the repainting operation by the painting means 120 to dry the painted portion of the hull S. [

That is, before the paint is sprayed, the heat of the heater 170 is dried to remove the moisture in the painting area, and after the re-painting, the evaporation component of the paint painted on the painting area is rapidly evaporated, Thereby prolonging the life of the battery.

An exhaust port 113 through which water vapor evaporated by the heater 170 is discharged is formed in the upper portion of the housing 110. The gas component evaporated by the heat generated by the heater 170 is discharged to the outside through the exhaust port 113. When the use of the heater 170 is completed, the stopper is covered to prevent the foreign matter from flowing.

2 and 3, a partition wall 160 may be provided on both the first glove 131 and the second glove 132 to form a flow boundary of the worker floating on the first glove 131 and the second glove 132.

As described above, in the semi-submerged hull repainting apparatus 100 of the present invention, when the diver on the outside of the housing 110 puts the hand on the glove 130, the painting means 120 inside the housing 110 is operated The following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings, hereinafter referred to as the drawings, when the water flow rate around the hull S is high. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

As shown in Figs. 1 and 2, the housing 110 is formed in a box shape having an opening on one side, for isolating a painted portion of a water immersion area from water.

As described above, in the semi-submerged hull repainting apparatus 100 of the present invention, when the diver on the outside of the housing 110 puts the hand on the glove 130, the painting means 120 inside the housing 110 is operated When the flow rate of water around the hull S is high, the worker is pushed by the flow energy of the water, so that the hand may fall off the glove 130. When the wave hits, And the inside of the housing 110 may be difficult to observe.

When the first partition 161 and the second partition 162 are formed on both the first glove 131 and the second glove 132, a flow boundary of the floated operator is formed, And the wave is weakened or lost by colliding with the first and second diaphragms 161 and 162, so that the operator's view is not disturbed.

According to the present invention, the housing 110 is detachably attached to the hull S along the periphery of the opening by means of the attaching / detaching means 111, so that the coating surface is separated from the water in the water immersion area of the hull (S) A recoating operation is carried out on the coated surface of the hull, the view of the operator is secured to the coated surface even in a cloudy water, and a semi-submerged hull re-coating apparatus 100 for isolating the operator from the foreign matter .

In addition, the housing 110 is provided with the partition wall 160 that forms the flow boundary of the worker floating, so that even if the wave is hit, the worker located in the water sweeps away from the painting surface by the fluid force of the wave It is possible to provide a semi-submerged hull repainting apparatus 100 which is constructed so as to be prevented from being damaged.
