Description

{Marine structure including wave generating device for preventing pirate invasion}

The present invention relates to a pirate intrusion prevention offshore structure.

Sometimes news is reported that pirates have been abducted by vessels operating on Somalia offshore. The intrusion of these pirates can occur not only in ships but also in floating offshore structures that stay in a fixed position.

A pirate usually approaches a side of a main body by using a small boat such as a rubber boat, and then raises the rope on the deck to take the ship. While the crew onboard the ship do not have weapons such as rifles, pirates have firearms, so once a pirate is on board, it is virtually impossible to prevent the ship from being abducted. Therefore, there is a need for a method that can prevent pirates from entering the main body.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, do.

FIG. 1 is a view showing a right side surface of an offshore structure including a wave device according to an embodiment of the present invention. FIG. 2 is a right side view of a section taken along the line AA in FIG. 1, 1 is a view of a part of a wave device according to an embodiment viewed from the right side.

Referring to FIG. 1, an offshore structure 1 includes a main body 10 and a wave device 100. Here, the offshore structure 1 may include, but is not limited to, floating offshore structures such as FPSO or the like.

On the right side surface of the main body 10, a plurality of holes 11 spaced from each other in the front-rear direction are formed. These holes 11 are also formed on the left side of the body 10, though not shown.

The hole (11) is located below the water surface and is immersed in water. A wave is generated in the lateral direction of the main body 10 when the wave device 100 described later repeatedly pushes the water inside the hole 11 to the outside.

Referring to FIGS. 2 and 3, the wave device 100 generates waves with a time difference in mutually adjacent holes 11 among the plurality of holes 11. FIG. The mechanism by which the wave generated by the time difference prevents pirate intrusion will be described later.

In this embodiment, the wave device 100 includes a cylinder portion 110, a piston portion 120, and a driving portion 130.

A plurality of cylinder portions 110 are provided corresponding to the respective holes 11. Each cylinder portion 110 is formed to extend in the vertical direction inside the side wall of the main body 10. For example, each of the cylinder portions 110 may be disposed in the internal space of the double partition wall structure of the main body 10. [

Each cylinder portion 110 is connected to each corresponding hole 11. The water introduced into each of the holes 11 can be introduced into the lower portion of each cylinder 110.

A plurality of piston portions 120 are provided corresponding to the respective cylinder portions 110. Each piston portion 120 reciprocates in each cylinder portion 110. In this embodiment, when the piston 120 moves downward, water in the cylinder 110 is pushed out through the hole 11 to generate waves. When the piston 120 moves upward, the external water flows into the cylinder 110 through the hole 11.

The piston portion 120 can reciprocate in a state of being in close contact with the cylinder portion 110. In this case, the water introduced into the cylinder 110 does not flow into the interior of the main body 10, for example, the internal space of the double partition wall structure. Alternatively, it may be used in various apparatuses and methods for preventing the water introduced into the cylinder unit 110 from flowing into the body 10.

The driving unit 130 reciprocates the neighboring piston units 120 of the plurality of piston units 120 with a time difference from each cylinder unit 110.

In this embodiment, the driving unit 130 includes a crankshaft 131 and a driving motor 133. [

The crankshaft 131 is connected to each piston 120. The crankshaft 131 includes a plurality of pairs of counterweight 1312 coupled by crank pins 1311 and has a structure in which they are mutually coupled by journals 1313. Each piston portion 120 is coupled to the crank pin 1311 of the crankshaft 131 by a connecting rod 132. [ When the crankshaft 131 is rotated, the respective piston parts 120 can reciprocate with a time difference by varying the engaging positions of the respective crank pins 1311 with respect to the counterweight 1312.

The drive motor 133 is connected to the crankshaft 131 to provide a rotational force. For example, the drive gear 134 is coupled to the motor shaft of the drive motor 133, and the driven gear 135, which engages with the motor shaft, may be coupled to one end of the crankshaft 131. The driving motor 133 can be fixedly installed inside the main body 10. [

When the drive motor 133 is operated to rotate the crankshaft 131, each piston 120 connected to the crankshaft 131 can reciprocate with the other piston 120 adjacent to the other.

The driving unit 130 constructed as described above has a simple structure and is easy to manufacture and install.

According to another embodiment, the driving portion may include a plurality of actuators (not shown) corresponding to each piston portion 120. At this time, each of the actuators reciprocates each of the piston parts 120. Then, each of the actuators operates so that mutually adjacent piston parts 120 reciprocate with a time difference.

In the wave device 100 having the above structure, the water is pushed in the neighboring cylinder part 110 with a time difference in the process of reciprocating the neighboring piston part 120 with a time difference, Generate waves with time difference.

4 is a diagram illustrating a mechanism for preventing a pirate intrusion according to an embodiment of the present invention.

Referring to Fig. 4, the pirate ship approaches from the right side of the offshore structure (1). At this time, the wave device 100 according to the present embodiment generates waves in the right direction of the main body 10 with a time difference in the neighboring holes 11.

The waves (indicated by long arrows and small arrows) generated with a time difference impact the pirate ship approaching the right side of the main body 10 with a time difference to weight the yawing of the pirate ship P. [

The pirate ship P having the weighted yawing is unbalanced and thus pirates aboard the pirate ship P are prevented from intruding into the main body 10
