[0018] The detailed description disclosed below, together with the attached drawings, is intended to describe exemplary embodiments of the present invention and is not intended to represent the only embodiment in which the present invention can be practiced.

[0019] In order to clearly explain the invention in the drawings, parts unrelated to the explanation may be omitted, and the same reference numerals may be used for identical or similar components throughout the specification.

[0020] In embodiments of the present invention, expressions such as “or”, “at least one”, etc. may represent one of the words listed together or a combination of two or more.

[0021] In the embodiments of the present invention below, the size, thickness, and shape of each component are illustrated in an exaggerated manner for convenience of explanation, and the actual mooring device may have different sizes and shapes.

[0022] Additionally, the connection structure of the illustrated wiring is depicted in a simplified manner for convenience, and different connection forms may be applied. Although the upper, lower, and side parts are indicated based on specific components, this is for the convenience of explanation and may be interpreted as a direction different from the designated direction depending on the rotation or arrangement of the device.

[0023] FIG. 1 is a side view of a mooring device according to one embodiment of the present invention.

[0024] Referring to FIG. 1, the mooring device of the present invention may include a moving means (110) and a bit member (120) connected to the moving means (110).

[0025] The means of movement (110) is provided on the hull (30) and can be positioned to move vertically along the outer surface of the hull (30) by means of a driving force provided from a motor (not shown).

[0026] The form of the means of movement (110) can be provided in a form that moves along a rail as in the drawing, and can be implemented in a rack-pinion manner.

[0027] For example, it may be provided in a form including a rack gear (not shown) provided longitudinally on the outer surface of the hull (30), a pinion gear provided inside the hull (30) to mesh with the rack gear, and a motor (not shown) for rotating the pinion gear.

[0028] Next, the bit member (120) is connected to the aforementioned moving means (110) and is provided on the outside of the hull (30), and a mooring line extending from the port mooring device (51) can be connected.

[0029] In the drawing, the bit member (120) is depicted as a hook shape protruding upward, but it is not limited to this shape; any shape that can securely fasten the mooring line is applicable.

[0030] As the bit member (120) of the present invention is connected to the moving means (110), it is possible to move vertically along the outer surface of the hull (30), and accordingly, even if the height of the port mooring device (51) of the dock (50) does not match the height of the bit member (120) provided on the hull (30), the height of the bit member (120) can be easily adjusted so that the mooring line can be formed stably.

[0031] Above, we have examined the basic configuration of the mooring device of the present invention.

[0032] However, the configuration of the means of movement of the present invention may be provided in the following form.

[0033] FIG. 2 is a perspective view of a moving means according to one embodiment of the present invention, and FIG. 3 is a plan view of the moving means of FIG. 2.

[0034] Referring to FIGS. 2 and 3, the moving means (110) may be provided to include a first member (113) movably disposed along a first rail (111) provided in a vertical direction on the hull (30) and a second member (117) movably disposed along a second rail (115) provided in a horizontal direction on the first member (113).

[0035] Referring to the drawing, a slit or groove may be formed in a vertical direction on the outer surface of the hull (30), and a first rail (111) may be provided in a vertical direction inside the slit or groove so that a first member (113) can move vertically along it.

[0036] At this time, the first part (1131) of the first member (113) can be embedded inside the groove or slit described above and arranged to allow vertical movement.

[0037] The second part (1132) of the first member (113) may be provided in a plate shape that protrudes horizontally from the first part (1131) and is positioned on the outer surface of the hull (30), with the horizontal direction being the longitudinal direction.

[0038] A second rail (115) is provided along the longitudinal direction of the second part (1132) on the second part (1132), and the second member (117) is arranged to be horizontally movable along the second rail (115), and a bit member (120) can be arranged to be connected on the second member (117).

[0039] As the moving means (110) of the present invention is provided in such a shape, it becomes possible to easily form a mooring line by moving the bit member (120) of the hull (30) in vertical and horizontal directions to match the mooring conditions of the port.

[0040] In addition, a moving means according to one embodiment of the present invention may further separately provide a fixing means (not shown).

[0041] According to one embodiment, the fixing means may be provided as a magnetic member.

[0042] Referring further to FIGS. 2 and FIGS. 3, a magnetic member is provided on one side of both ends of the first member (113) to selectively fix the first member (113) to the outer surface of the hull (30), and a magnetic member may also be provided inside the second member (117).

[0043] When the vertical or horizontal movement of the bit member (120) is completed, a controller to be described later may be configured to control the magnetic members of the first member (113) and the second member (117) to fix the first member (113) and the second member (117) to the outer surface of the hull (30).

[0044] According to one embodiment, the fixing means may be provided as an electromagnet, and by applying or cutting off current to the electromagnet, the fixing of the moving means (110) can be controlled.

[0045] Since the hull (30) is generally made of steel which is a ferromagnetic material, the aforementioned moving means (110) can be easily fixed to the outer wall of the hull (30) through a magnet.

[0046] The flow of current is configured to be controlled through a controller, so that when current is applied, the fixing means can be magnetized and fixed to the outer wall of the hull (30), and when the current is cut off, the moving means (110) can be moved again on the hull (30).

[0047] As the moving means (110) of the present invention further comprises a fixing means, the mooring line can be maintained more stably through the fixing means during mooring operations.

[0048] In addition to this, a mooring device according to one embodiment of the present invention may further include the following components.

[0049] A mooring device according to one embodiment of the present invention may further include a sea level sensor and a receiver.

[0050] Referring again to FIGS. 1 to 3, a sea level sensor (not shown) is provided on the hull (30) and functions to measure the sea level height by determining the degree to which the hull (30) is submerged in water.

[0051] The degree to which the hull (30) is submerged in water varies depending on the load of the vessel, and a sea level sensor is provided to measure the degree to which the vessel is submerged in water in order for this sea level height to satisfy the waterline.

[0052] The controller of the present invention can determine the sea level height received from the sea level sensor, that is, the extent to which the hull (30) is submerged from the sea level.

[0053] By utilizing this, the distance from the sea level to the bit member (120) can be calculated, making it possible to move the bit member (120) to a desired height.

[0054] Next, a receiver (not shown) is provided inside the hull (30) and functions to receive port information.

[0055] Port information may include at least one of the height of the pier (50) of the target port where the hull (30) is to dock, the height of the port mooring (51), and the distance from the sea level to the port mooring (51).

[0056] Although not shown in the drawing, the receiver may be provided to be wirelessly connected to the management module of the target port where the hull (30) is to dock.

[0057] The receiver may be configured to enable communication with a management module provided in the port by including a communication module that is embedded in or controlled by a central processing unit (CPU), microprocessor, ASIC, etc., to support WPAN, WiFi, 3G / 4G / LTE, Bluetooth, Ethernet, BcN, satellite communication, Microware, serial communication, PLC local ad-hoc network, the Internet, etc.

[0058] In addition to this, the receiver may be configured to receive additional location information of the port mooring device (51).

[0059] The management module equipped in the port receives GPS coordinate signals from a GPS satellite to receive location information of the port mooring device (51), and the receiving unit likewise receives GPS coordinate signals from a GPS satellite to receive real-time location information of the bit member (120) equipped in the hull (30).

[0060] In addition, the receiving unit receives location information from the port management module and transmits it to the controller described later, along with the location information of the hull (30).

[0061] The sea level height received from the aforementioned sensor and the port information and location information of the port mooring device (51) received from the receiver are used as information based on the controller when controlling the vertical and horizontal movement of the bit member (120).

[0062] In addition, a mooring device according to one embodiment of the present invention may further include a controller (not shown).

[0063] The controller functions to increase the mooring stability of the mooring line by controlling the vertical movement of the bit member (120) according to the measured sea level height and received port information, and may be configured to control the horizontal movement of the bit member (120) based on the position information of the received port mooring device (51).

[0064] The controller may be provided to enable wireless communication with a worker terminal by including a wireless transmission unit that wirelessly transmits the measured value of a load cell to a remote location according to at least one communication protocol among ZigBee communication, CDMA communication, RF communication, infrared communication, and Bluetooth.

[0065] Below, the mooring method using the aforementioned controller is explained in more detail.

[0066] FIG. 4 illustrates a method for adjusting the vertical position of a bit member using a mooring device according to an embodiment of the present invention.

[0067] Referring to FIG. 4, when a receiver receives port information from a port and a sea level sensor measures the height of the sea level and transmits it to a controller, the controller can determine the vertical movement distance of the bit member (120) based on the port information and control the vertical movement.

[0068] In one embodiment, when the distance from the sea level to the port mooring device (51) is provided, the bit member (120) can be moved by the difference value compared with the sea level height measured by the sea level sensor to control the height to correspond to the height of the port mooring device (51).

[0069] In another embodiment, when the height of the pier (50) of the target port to which the hull (30) is to dock and the height value of the port mooring device (51) are provided, the bit member (120) can be moved to a height corresponding to the sum of the two height values ​​and controlled to a height corresponding to the height of the port mooring device (51).

[0070] Next, FIG. 5 illustrates a method for adjusting the horizontal position of a bit member using a mooring device according to an embodiment of the present invention.

[0071] Referring to FIG. 5, a receiver may be provided to receive location information of a port mooring device (51), and a controller may determine this to control the location of a bit member (120) on a horizontal plane.

[0072] When the receiver transmits location information of the port mooring device (51) and the location information of the hull (30) bit member (120), the controller can compare the location and arrangement spacing of the port mooring device (51) and the hull (30) bit member (120) based on this.

[0073] Afterwards, by individually controlling the horizontal movement direction and distance of the bit member (120), it is possible to move the bit member (120) to a position corresponding to the position of the port mooring device (51).

[0074] At this time, as the hull (30) moves toward the port, the position information of the bit member (120) may change moment by moment, so the horizontal movement control of the bit member (120) can be performed in real time along with the movement of the hull (30).

[0075] In addition, the aforementioned vertical and horizontal movement control can be performed simultaneously, and the horizontal movement can be implemented to be controlled in detail after the vertical movement is completed.

[0076] In this way, as the mooring device of the present invention includes a sea level sensor, a receiver, and a controller together, it becomes possible to more accurately measure and compare port conditions and mooring conditions of the hull (30).

[0077] Accordingly, the height and spacing of the bit member (120) most suitable for port conditions can be set, thereby improving the stability and efficiency of mooring operations.

[0078] Furthermore, a mooring device according to one embodiment of the present invention may be provided in various forms as follows.

[0079] According to one embodiment of the present invention, at least one bit member may be disposed on the hull.

[0080] At this time, a corresponding motor (not shown) may be disposed in each bit member so that the controller can independently select and control it.

[0081] FIG. 6 illustrates a mooring method using a mooring device according to an embodiment of the present invention, showing an embodiment in which only the 1st, 3rd, 5th, and 7th bit members from the left are used for mooring operations so as to correspond to the spacing between port mooring devices.

[0082] Referring to FIG. 6, if the spacing of the port mooring device (51) installed on the dock (50) does not correspond to the bit member (120) provided on the hull, it is possible to select and independently control only the bit member (120) suitable for mooring work, rather than using all bit members (120).

[0083] In the drawing, for the 3rd bit member (120) and the 5th bit member (120), the angle of the mooring line from the hull to the port mooring device (51) is controlled to be vertical.

[0084] In the case of the 1st and 7th bit members (120), the mooring angle is widened to secure a stable mooring line so as to prevent the hull from drifting away in the flow of seawater.

[0085] That is, the first bit member (120) can move the second member (117) horizontally to the leftmost position on the first member (113) of the moving means (110), and in the case of the seventh bit member (120), conversely, the second member (117) can be moved to the rightmost position on the first member (113).

[0086] In this way, when using the mooring device (100) according to one embodiment of the present invention, the angle of the mooring line can be adjusted more finely by selecting whether to use the bit member (120) according to the requirements of the target port where the hull (30) is to dock, thereby having the advantage of improving mooring work efficiency and stability.

[0087] In addition, according to one embodiment of the present invention, the bit member may be provided to have a rotating drum.

[0088] FIG. 7 is a perspective view of a bit member according to one embodiment of the present invention.

[0089] Referring to FIG. 7, the rotating drum (121) may be configured to rotate around a virtual axis of rotation, and may be provided to wind or unwind the mooring line by controlling the direction of rotation during rotational movement.

[0090] In one embodiment, the rotating drum (121) may be provided to wind the mooring line after the mooring operation of the hull is completed, retrieve it to the hull side, and store it.

[0091] When the rotating drum (121) of the present invention is used in conjunction with the sea level sensor described above, it has the advantage of preventing the rotating drum (121) from going below the sea level, thereby minimizing corrosion by seawater.

[0092] Here, a bit member according to one embodiment of the present invention may be provided to further include a tension sensor together with a rotating drum.

[0093] The tension sensor functions to measure the tension of the mooring line connected to the bit member.

[0094] Accordingly, the mooring device of the present invention can be configured to independently adjust the tension of each mooring line applied to the bit member based on the tension value received from the tension sensor.

[0095] At this time, if the measured tension value of the mooring line deviates from a preset range, the controller can control the moving means to move the bit member horizontally or left and right so that the measured tension satisfies the preset range.

[0096] As the bit member is moved in this manner, the formation of the mooring line is completed when the tension value applied to the mooring line satisfies a preset range.

[0097] If the measured tension does not satisfy a preset range within a preset time, it may be determined that there is a bit absence or an operating error of the tension sensor, and the controller may be configured to notify the operator by transmitting this to the operator terminal.

[0098] As the mooring device of the present invention includes the tension sensor and controller described above, when the hull moves or the distance from the dock changes due to external environmental conditions during the formation of mooring lines, the real-time tension of each mooring line can be checked by the tension sensor.

[0099] In this case, when a rotating drum is provided in the bit member of the present invention, the tension applied to the mooring line can always be maintained constant by adjusting the winding and unwinding of each mooring line according to the measured tension, thereby providing the advantage of performing mooring operations more stably.

[0100] In addition, since the present invention includes a controller, real-time monitoring is possible through a worker terminal without the worker having to manually manage multiple bit members, and the controller can be controlled via the worker terminal, thereby improving mooring work efficiency.

[0101] In addition, it has the effect of preventing potential accidents by immediately notifying the operator of any malfunction in the mooring device.

[0102] As described above, using a mooring device according to one embodiment of the present invention can provide the following advantages.

[0103] Conventionally, when a hull berths at a port, there was a difficulty in easily adjusting the angle of the mooring line if mooring conditions, such as the height of the pier, the height of the port mooring equipment, and the spacing between mooring equipment, did not match the bit members of the hull.

[0104] Consequently, when the inclination and angle of the mooring line are formed abruptly, there has been a problem in that it is difficult to stably support the hull, as the mooring line cannot withstand the tension and becomes damaged.

[0105] However, by using the mooring device of the present invention, it becomes possible to move bit members in vertical and horizontal directions according to the mooring conditions of the port, and the spacing between bit members can be easily adjusted.

[0106] Accordingly, it is possible to satisfy mooring conditions suitable for the port situation, thereby having the advantage of improving mooring efficiency and stability.

[0107] Although the mooring device of the present invention described so far in this specification has been explained with the example of berthing at a port, the berthing target is not limited thereto and can also be utilized for mooring between marine structures or between ships.

[0108] The embodiments of the invention disclosed in this specification and drawings are provided merely as specific examples to facilitate the explanation of the technical content of the invention and to aid in understanding the invention, and are not intended to limit the scope of the invention.

[0109] Accordingly, the scope of the present invention should be interpreted as including all modifications or variations derived based on the technical concept of the present invention, in addition to the embodiments disclosed herein. Explanation of the symbols
