Description

ANTI-FOULING APPARATUS OF SHIP}

The present invention relates to a marine anti-fouling device, and more particularly to a marine anti-fouling device that generates ultrasonic waves on a surface of a marine vessel to prevent marine life from adhering to the marine vessel.

When a marine creature such as a barnacle attaches to the bottom of a ship at a low speed operation or anchorage of the ship, the frictional resistance of the bottom part increases, thereby reducing the operational efficiency of the ship and increasing fuel efficiency. Therefore, there is a need to prevent marine organisms from adhering to the hull, which is called anti-fouling. For example, in order to prevent marine life from adhering to the hull, an antifouling coating is coated on the bottom of the ship. However, the antifouling coating is peeled off over time or the film thickness is thinned, and the antifouling performance is deteriorated. Therefore, it is necessary to repaint the antifouling paint after a certain period of time. In addition, in the case of an antifouling paint having excellent antifouling performance, there is also a problem that the antifouling cost is increased because it is expensive. In addition, since marine organisms adhering to the bottom of the vessel during the drying operation while the vessel is anchored before the antifouling paint is formed on the bottom of the vessel must be removed by using a diver, labor costs are increased, .

An object of the present invention is to provide a marine anti-fouling device capable of easily installing an ultrasonic wave generating device for preventing marine life from adhering to a hull.

The problems to be solved by the present invention are not limited to the above-mentioned problems. Other technical subjects not mentioned will be apparent to those skilled in the art from the description below.

The marine anti-fouling device may further include a buoy provided on the ultrasonic wave generator.

The marine anti-fouling device comprises: a guide body coupled to the buoy; And a guide bar formed on the guide body. The guide bar may be coupled to a guide groove formed in the distal-side guide member.

The ship anti-fouling device may further include a winch provided on a deck of the ship, and a winch for adjusting a position of the ultrasonic generator by winding or loosening a wire connected to the ultrasonic generator.

The marine anti-fouling apparatus 100 generates ultrasonic waves from the ultrasonic wave generator 140 attached to the hull 11 toward the surface of the hull 11 to prevent the marine creature from adhering to the hull 11. The ultrasonic generator 140 generates ultrasonic waves in a horizontal direction parallel to the surface of the hull 11 through the ultrasonic tips 140a provided on both sides to prevent the marine organisms from adhering to the surface of the hull 11. That is, the ultrasonic waves generated by the ultrasonic wave generating device 140 form vibrations in water, and the vibration prevents the attachment of marine life such as a barnacle to the surface of the ship 11.

In this embodiment, the anti-fouling system 100 includes a rotating plate 123, a guide unit 130, and an ultrasonic generator 140. The guide part 130 is provided to guide the ultrasonic generator 140 to the hull 11 to an antifouling position expected to attach marine life. The guide portion 130 can be rotatably installed on the deck side hull of the ship 10.

In one embodiment, a support plate 111 is provided on the upper side of the hull 11 and a case 121 is provided on the support plate 111. A rotating plate 123 is rotatably installed on the case 121 on the upper edge side of the hull. In the case 121, a bearing 122 for rotatably supporting the rotating plate 123 on the case 121 is provided. The guide portion 130 is connected to the side surface of the rotary plate 123 by a hinge shaft 130a so as to be vertically rotatable with respect to the rotary plate 123. [ The guide portion 130 is supported on the case 121 before being mounted on the hull 11. Reference numeral 112 denotes a guide plate for supporting the marine anti-fouling apparatus 100 on the upper side of the ship 11 in contact with the side surface of the marine vessel 11.

The guide portion 130 includes a plurality of guide members 131, 132, and 133 coupled in a telescopic structure. In the illustrated embodiment, the guide unit 130 includes first to third guide members 131, 132, and 133. A second guide member 132 is inserted into the first guide member 131 and a third guide member 133 is inserted into the second guide member 132. In the illustrated embodiment, the guide member 130 is composed of three guide members 131, 132, and 133, but the number of the guide members may be variously changed according to the size of the ship 10, marine environment conditions, and the like.

Guide grooves 131a, 132a, and 133a are formed in both sides of the guide members 131, 132, and 133 in the insertion direction of the guide members 131, 132, and 133. The guide protrusions 132b formed on both side end sides of the second guide member 132 are installed to be movable in the guide grooves 131a by being engaged with the guide grooves 131a of the first guide member 131. The guide protrusions 133b formed on both side end sides of the third guide member 133 are installed to be movable in the guide groove 132a by being engaged with the guide groove 132a of the second guide member 132. [

The ultrasonic wave generator 140 is installed on the distal end side of the guide portion 130, that is, on the third guide member 133. The ultrasonic generator 140 generates ultrasonic waves to prevent the marine creatures from adhering to the hull. The ultrasonic wave generator 140 is connected to the wire W. The wire W is connected to a winch (not shown) provided on the deck. The winch can be rotated to unwind or loosen the wire W to adjust the position (height) of the ultrasonic wave generator 140 or to hoist the ultrasonic wave generator 140 to the deck side

2, when the guide part 130 is rotated, the guide part 130 is rotated about the hinge shaft 130a by the gravity so as to be directed downward, and the guide parts 130, 132, As shown in Fig. 3, and is provided on the side of the hull 11 as shown in Fig. The guide portion 130 may be manually rotated by an operator, or may be provided to be rotated by a driving means such as a motor / speed reducer. In one embodiment, the anti-fouling system 100 may include a hoist (not shown). The hoist may be provided to unfold the wire to unfold the guide portion 130 and to fold the guide portion 130 by winding the wire.

FIG. 4 is a perspective view showing the interior of the 'B' portion shown in FIG. 3, FIG. 5 is a plan view showing the 'B' portion shown in FIG. 3, and FIG. 6 is a side view showing the 'B' portion shown in FIG. 4 to 6, the ultrasonic generator 140 may be provided with a buoy 150 to float on the sea surface. The buoy 150 is provided to adjust the position of the ultrasonic generator 140 according to the draft of the ship 10.

A guide body 141 is provided at the upper portion of the buoy 150. Guide bars 142 each having a rod shape are coupled to both sides of the guide body 141. Both ends of the guide bar 142 are engaged with guide grooves 133a formed in the longitudinal direction on both side portions of the third guide member 133 of the guide portion 130 so as to be movable in the guide groove 133a do. Thus, according to the present embodiment, when the buoy 150 floats on the sea surface, the ultrasonic tip 140a of the ultrasonic generator 140 is located at a depth where the marine life below the sea surface is well adhered to improve the antifouling performance. Even if the sea level fluctuates due to waves, the guide body 141 can be stably guided in the vertical direction by the guide bar 142 coupled to the guide groove 133a of the guide member 133, .

As described above, the anti-fouling system 100 according to the present invention can easily install or remove the ultrasonic generator 140 from the deck of the ship on the surface of the ship 11. Therefore, when marine life is likely to adhere to the surface of the ship, such as at the time of anchorage or low-speed navigation, the guide portion 130 is lowered to the side portion of the ship 11 to prevent the marine life, It is possible to increase the operating efficiency of the ship by hoisting the guide unit 130 and the ultrasonic generator 140 with a deck so that the frictional resistance of the ship's anti-fouling apparatus is prevented from increasing.
