Description

Technical Field [0001] The present invention relates to a system for removing fouling using a vibration generator,

The present invention relates to a system for removing fouls of a ship using a vibration generator, and more particularly, to a system for converting a vibration generated in a vibration generator into an in-plane wave and transmitting the vibration to a surface of a ship, To a foul removal system for a ship using a vibration generator in which marine life is removed.

The lower part of the water line below the water line where the hull is submerged is attached to various kinds of marine life. Such marine life increases the weight of the hull, increases the resistance and increases the fuel consumption, The shipbuilding industry is constantly making efforts to suppress the attachment of marine life below, and fuel consumption has increased exponentially in recent years due to the increase in size and speed of ships.

Ship hull contaminants may be removed using mechanical or chemical means when the ship is at berth. However, these alternatives can not be used frequently or can only be used after a long wait. When a ship hull or structure is being cleaned in place, it is common to use a diver, but there is a risk of intrinsic whenever the diver gets into the sea. Also, when the ship hull is cleaned in dry-dock, the ship must be delivered to the nearest available gun election, which is usually the cost of the work required, as well as the cost of the shutdown time Resulting in a disadvantageous financial result. Moreover, the elimination of external additives while in the election can cause considerable regulatory environmental problems. It is impractical to remove the fastening structure from a predetermined position for cleaning.

Conventionally, a technique has been used which uses toxic paints that release marine biosynthesis agents at low speeds or that makes it difficult for contaminated creatures to adhere to the surface of ship hulls using extremely smooth silicone-based paints. However, since the antifouling component is dissolved into the seawater by the reaction with the sea water, the durability of the coating film is lowered and the repair coating should be performed frequently. The antifouling component remains in the marine environment for a long time, You can.

Conventionally, when a piezoelectric element is used to remove marine life, if a voltage is applied to the upper and lower portions of a disk type piezoelectric element, a plate having a piezoelectric element attached thereto repeatedly expanding and contracting in a radial direction Plane mode, thereby causing a change in stress distribution in the thickness direction of the plate and delamination at the surface of the plate, thereby eliminating fouling of the surface. In this case, However, in the case of ships, the structure is relatively thick and heavy, so that there is a problem that sufficient excitation force can not be generated.

The vibration generator 110 may be a vibrator for a ship. Since the hull is made of a steel plate having a thickness of 1 cm or more, the vibration generated by the vibration generator 110 must be outputted over a certain range so as to be transmitted to the surface of the ship.

The vibration generated by the vibration generator 110 may be transmitted to the vibrating pad 120 attached to the surface of the ship and may transmit the vibration of the pad 120 to the surface of the ship.

The holding pad 120 may be formed integrally with the magnet 125. The magnet 125 may be a permanent magnet that can be attached to or detached from the hull by generating or dissipating magnetic force by a switch. So that the magnet can be firmly fixed to the hull so that the magnet does not separate from the hull.

The vibration transmission unit 180 may transmit the vibration to the pad 120 having the vibration generated by the vibration generator 110. The vibration transmission unit 180 may be connected to the lower portion of the vibration generator 110, A first cylinder device 130 and a first cylinder device 130 are fixed to the support 120.

The vibration transmission bar 150 is fixed to the first piston rod 132 of the first cylinder device 130 and the other end of the vibration transmission bar 150 by the vibration generated by the vibration generator 110, When one piston rod 132 reciprocates in the vertical direction, one end of the vibration transmission bar 150 moves upward and downward, and the other end of the vibration transmission bar 150 moves in the left and right direction.

That is, when the first piston rod 132 moves downward, one end of the vibration transmission bar 150 connected to the first piston rod 132 also moves downward. At the same time, the other end of the first piston rod 132 The connected vibrating pad 120 may be moved in a direction away from the vibration generator 110. At this time, the second cylinder device 140, which is connected to the supporting part 160 at one end and connected to the pad 120 at the other end, may also be relaxed.
