The smart harbor system has a space in which cargo C can be loaded and floats on the sea, and is installed on the bottom of the sea to be in contact with the bottom of the float 100, Foundation 200 to prevent rocking, the docking unit 120 and the docking unit 120, which is installed on the floating vessel 100 and the container ship (S), is installed on the floating body 100 between the container ship (S) It may be configured to include a crane 110 for performing the loading and unloading of the cargo (C).

Floating body 100 may be a vessel provided with a propulsion device to be able to move itself, a floating body of various forms such as a general barge can be used. In this case, the floating body 100 may move to perform cargo unloading between the pier or other container ship of the land. On the other hand, the floating body 100 may have its own propulsion device or may not have power to move by itself. One or more sides of the floating body 100 may be formed in a structure capable of unloading the cargo (C) between the shuttle barge 300 and docked with the shuttle barge (300). Shuttle barge 300 is to move in the sea to perform the cargo unloading between the pier or other container ships of the land.

The foundation 200 reduces the fluctuation of the floating body 100 due to an external force such as wind, blue, or algae, in particular the rolling and pitching movement of the floating body 100, thereby reducing the amount of the floating body 100. The stable cargo unloading between container ships S is enabled, and the specific structure is mentioned later.

The docking unit 120 is installed in plural on the side of the floating body 100 to enable a stable docking despite the curved surface of the container ship (S).

In addition, as the crane 110, a suitable one can be selected and used from various types of cranes, such as a pedestal crane, a portal crane, and a gantry crane, for example.

On the other hand, the smart harbor system may further include a power hookup 140 for supplying power to the floating body 100 from the land and the oil hookup 150 for supplying oil to the container ship (S). Here, the power hook-up 140 functions to supply electricity to the propulsion device and the crane 110 of the floating body 100 and to supply a fluid such as compressed gas to the foundation 200.

Hereinafter, the configuration of the foundation 200 according to the present invention will be described in detail with reference to FIG. 3.

The foundation 200 is basically provided on the base 210 of a plate-like structure which is fixedly installed on the bottom of the sea floor, and is provided on the base 210, and when fluid is supplied therein, the foundation 200 extends toward the sea surface to form the bottom of the float 100. A plurality of jig element (220) to be in contact with, and a fluid supply pipe 230 for supplying a fluid to each jig element 220 is configured.

The jig element 220 has a structure such as a bar antenna that can be freely stretched by stacking several metal pipes of different diameters one after another. The jig element 220 increases in length when a fluid (for example, compressed air) is supplied therein. It is configured to reduce the length when the fluid is discharged. In addition, when the amount of the fluid supplied to each jig element 220 is adjusted individually to adjust the amount of extension or contraction of each jig element 220, the height from the base 210 to the tip of each jig element 220 is adjusted. Can be controlled.

On the other hand, one embodiment of the present invention has a total of 25 jig elements 220 arranged in five rows on the base 210, each jig element 220 is connected to the fluid supply pipe 230, each fluid The supply pipes 230 are all connected to the fluid supply pipe integration connector 240. The fluid supply pipe integration connector 240 connects the fluid supplied from the fluid supply (eg, the air compressor) provided in the floating body 100 to the respective jig elements 220 through the fluid supply pipe 230. To distribute.

When fluid is supplied from the fluid supply, each jig element 220 extends below sea level to a predetermined height depending on the amount of fluid supplied. For example, if the floating body 100 is a barge and the bottom thereof is flat, the height of all the jig elements 220 may be the same, but the floating body 100 may be an oil tanker or a container ship having a streamlined bottom. In this case, the amount of extension of each jig element 220 may be set differently according to the shape of the bottom of the float 100. For example, in FIG. 4, the jig element 220-1 corresponding to the center portion of the floating body 100 sets the elongation amount to be the smallest, and the jig element 220-2 located on both sides of the jig element 220-2 further extends the elongation amount. The jig element 220-3, which is set larger and located farthest from the center of the float 100, sets the elongation amount to the largest so that the curve connecting the distal end of the jig element 220 is increased. It can be made to form a gentle curve corresponding to the bottom of.

On the other hand, in one embodiment of the present invention, as shown in Figure 5, the distance measuring sensor for measuring the distance between the bottom surface of the floating body 100 and the jig element 220 at the tip of each jig element 220 By providing 225, it is possible to feedback-control the amount of elongation of each jig element 220 based on the measured value, so that it is possible to more stably prevent the floating body from floating. On the other hand, instead of the distance measuring sensor 225 as a component installed at the front end of the jig element 220, a pressure sensor is used to measure the pressure applied to each jig element 220 from the bottom of the floating body 100. It may be.

On the other hand, as shown in Figure 2, the smart harbor system of the present invention is a configuration for supplying electricity to the propulsion device and the crane 110, etc. of the floating body 100 and the foundation 200, power hook-up 140 and various cables connected thereto (ie, fluid supply hoses and power supply cables, etc.) 270. Here, the power hook-up 140 is preferably a buoy (buoy) that can be connected to the various cables 270 and floating on the sea surface using buoyancy. In addition, the various cables 270 are divided into a portion connecting the power hook-up 140 and the foundation 200, and a portion connecting the power hook-up 140 to a land power supply / fluid supply source (not shown). For reference, these cables 270 need not always be connected to the power hook-up 140 and / or the foundation 200 and the like, and may be separated from them as necessary.

When the cargo is unloaded between the smart harbor system and the container ship using the smart harbor system having the foundation 200 according to the present invention configured as described above, the jig element 220 supplied with the fluid is raised to When contacted with the bottom of the float 110, the foundation 200 is in contact with the bottom of the float 100 during the unloading operation of the cargo (C) and prevents the swing of the float 100, stable cargo Unloading is possible. In addition, since the foundation 200 according to the present invention can control the rising amount of each jig element 220 differently from each other corresponding to the shape of the bottom of the floating body 100, the bottom shape of the various floating body 100 Can be easily responded to.
