In the following description with reference to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, A description thereof will be omitted.

As described above, there is a need for a new mooring system capable of stably mooring the marine floating structure to the ship or the ship-to-ship or between the marine floating structure / ship to the mooring. Specifically, mooring availability may be significantly reduced if the drift difference between the marine floating structure and the ship is too great, for example, when the marine floating structure and the ship are side by side mooring. Therefore, there is a need for a new mooring system that can easily solve such a problem.

FIG. 1 is a view showing an example in which a mooring device according to an embodiment of the present invention is installed in a ship or a floating structure of a marine vessel. FIG. 2 is a cross- Fig. 2 is a cross-sectional view of a mooring device according to the present invention. 3 is a view schematically showing the operation principle of a mooring device according to an embodiment of the present invention. 4 is an enlarged view of a moving body and a rotating drum in a mooring apparatus according to an embodiment of the present invention.

1 to 4, a mooring apparatus 1000 according to an embodiment of the present invention may include a channel 100, a moving body 200, a rotary drum 300, and a first driving unit 400 have.

The channel 100 is configured to form a moving path so that the moving body 200, which will be described later, can move up and down as shown in FIG.

Referring to FIG. 2, the channel 100 may have an open shape. Specifically, the channel 100 may be a pipe-shaped member having a slot 110 opened at one side thereof. For example, the channel 100 may be a member having a cross-section of a "C" shape. In addition, if the channel 100 is provided with a slot 110 at one side thereof, the channel 100 may be a member having a cross-section of various shapes such as a polygon.

In addition, the channel 100 may be installed in a marine floating structure or a ship's side or quay's quay. Although the channel 100 is installed so as to protrude outward from the marine floating structure or side of the ship, the present invention is not necessarily construed to be construed as being limited thereto. The channel 100 may be a floating structure, Or may be installed to be recessed inward from the side wall or the quay wall.

The moving body 200 is arranged in the inner hollow portion of the channel 100 and is movable up and down. Referring to FIG. 2, the moving body 200 may have a cross-section corresponding to the cross-sectional shape of the channel 100. In this case, the mobile body 200 may have a circular cross-section corresponding to the circular channel 100. Further, a moire ring line 30 may be connected to the moving body 200.

According to the present embodiment, the movable body 200 may be constituted by a pair of support plates 210. A groove 220 may be formed at the edge of each support plate 210. The groove 220 may be engaged with the protrusion 120 provided on the inner side of the channel 100. Referring to FIG. 3, the protrusions 120 may extend up and down along the longitudinal direction of the channel 100. Therefore, even if the rotary drum 300 rotates to wind or unwind the mooring line 30, the supporting plate 210 of the moving body 200 having a circular cross-section is rotated by the rotary drum 300 to rotate .

The mooring apparatus 1000 may further include a second driving unit (not shown) for moving the moving body 200 up and down so that the moving body 200 can move up and down through the channel 100. For example, the second driving unit (not shown) includes a rack gear (not shown) provided in the longitudinal direction inside the channel 100; A pinion gear (not shown) provided outside the moving body 200 to be engaged with the rack gear; And a motor (not shown) for rotating the pinion gear.

In addition, if the movable body 200 can move up and down with respect to the channel 100, the second driving unit (not shown) can be variously modified.

As the moving body 200 connected to the mooring line 30 moves up and down through the channel 100 as described above, for example, even if there is a large difference in drift between the marine floating structure and the vessel or between the vessel and the vessel, The inclination of the mooring line 30 can be adjusted as needed, thereby greatly improving the mooring availability between the two structures (or vessels).

In this case, the mooring device 1000 may further include a tilt sensor (not shown) so that the degree of tilt of the mooring line 30 can be confirmed. Therefore, when the inclination of the moire ring line 30 is adjusted through the moving body 200, the information measured by the tilt sensor (not shown) is fed back to the controller (not shown) (Horizontal) can be maintained more accurately.

The rotary drum 300 is installed in the moving body 200 and is configured to wind, loosen or wind the mooring line 30.

4, the rotary drum 300 is interposed between the moving bodies 200 constituted by the pair of support plates 210, and can be rotated through a motor 410 fixed to the support plate 210. As shown in FIG. Accordingly, the rotary drum 300 can rotate around a virtual central axis with respect to the support plate 210 in a relatively fixed state, and by rotating the rotary drum 300, The mooring line 30 in a state of being released can be unwound or reversed outward as shown in Fig.

One end of the mooring line 30 may be wound on the outer side of the rotary drum 300 disposed inside the channel 100 and the other end of the mooring line 30 may be wound on the slot 110 of the channel 100. [ As shown in FIG. 1, the other end of the mooring line 30 may be secured to a mooring line fastening device (eg, Quick Release Hook) provided on an adjacent marine floating structure or ship 20.

As the mooring line 30 is loosened or rolled by using the rotary drum 300, for example, even if the mooring distance (spacing distance) between two ships (or structures) varies from time to time due to the external environment, 30) to maintain a certain level of tension at all times, so that it is possible to more stably and reliably moor the marine floating structure, the ship or the ship, or the marine floating structure / ship and the seashore.

Meanwhile, the first driving unit 400 provides a rotational force to rotate the rotary drum 300 relative to the moving body 200 in a relatively fixed state. For example, the first driving unit 400 may include a motor 410 fixed on a moving body 200 composed of a pair of support plates 210 as described above, (Not shown) for providing power and a control unit (not shown) for controlling the operation of the motor 410.

2, when the mooring line 30 is inserted into the channel 100 through the slot 110 or is discharged to the outside, the mooring line 30 is formed in the channel 100, A guide roller (not shown) may be installed adjacent to the slot 110 to prevent interference between the slot and the slot.

As described above, according to the embodiments of the present invention, the moving body is moved up and down so that the slope of the mooring line is horizontal, or the mooring line is loosened or rolled by using the rotating drum, And a mooring device capable of mooring more stably between the ship or the marine floating structure / ship and the seawall.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
