Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a buoy mooring device for a ship having a bulbous bow.

(Prior Art) Conventionally, when a ship or the like is moored to a buoy, the assistance of a support vessel is required to handle the mooring rope or chain, and a large amount of manpower is required.

However, in recent years, the development of automated ships or super-automated ships has progressed, and there is a growing demand for a device that can automatically moor to a buoy without the need for a support ship using equipment only on the ship or buoy side.

(Summary of the invention) The present invention was made in response to the above-mentioned requirements, and aims to provide a device capable of mooring a buoy without requiring a support vessel.

The buoy mooring device of the present invention includes a recess provided at the center of the bow, a mooring arm that fits into the recess, and a spherical bow fixed to the lower end of the mooring arm.

The recess is provided along the bow line and stores a mooring arm, which will be described later.

The upper end of the mooring arm that fits into the recess is pivotally supported by the hull for vertical rotation, and normally hangs downward and is stored in the recess, but when the mooring arm is moored, it is lifted forward of the bow by a drive device.

The spherical bow fixed to the lower end of the mooring arm is made detachable by separating the spherical bow from the hull structure, which was originally part of the hull structure, and is equipped with a buoy anchoring structure. According to the structure, when the vessel is moored, it is lifted from the hull by the mooring arm and anchored to the buoy.

(Example) Examples of the present invention will be described below based on the drawings. FIG. 1 is an explanatory diagram showing an embodiment of the present invention.

A recess 1 is provided along a bow line L at the center of the bow of the hull X.

The mooring arm 2 is configured to have a shape equal to the curve of the recess 1, and is normally fitted and stored within the recess 1, with its outer side forming the bow line L. As shown in FIGS. 2 and 3, this mooring arm 2 has an arm 20 attached to its upper end that protrudes toward the hull X side.
Hinge 21, 21 where 0 is attached to the hull
is supported by a shaft 22 passing through them,
It is designed to be able to rotate up and down. Various types of drive devices can be used to rotate this mooring arm 2, but in this embodiment, a rack hinge 23 is attached to the arm 20 and engages with a pinion gear 25 rotated by a motor 24, so that the pinion When the gear 25 rotates, the rack hinge 23 rotates accordingly, causing the mooring arm 2 to rotate vertically via the arm 20.

The spherical bow 3 forms a part of the hull structure during navigation, and in the present invention, it is made detachable and separate from other parts of the hull structure, and is fixed to the lower end of the mooring arm 2. It is configured so that it can be lifted forward to the bow of the ship or returned to the X side of the ship as it rotates. Further, this spherical bow 3 is provided with a buoy locking structure, and various types of structures can be used, but in this embodiment, a buoy locking structure is provided inside the surface in contact with the hull X as follows. There is. That is,
This buoy locking structure is illustrated in FIGS. 4 and 5. Contact side Y of the spherical bow 3 with the hull X
A hole 30 is provided inside, and a plurality of tapered holes 31 (four in this example) are provided in the circumferential direction on the outside.
A stopper 32 is loosely fitted therein. As shown in FIG. 5, when the stopper 32 is above the tapered hole 31, the stopper 32
0, and when it is on the lower side, it protrudes toward the hole 30 side and narrows the hole diameter. An electromagnet 33 is attached to the upper end of each tapered hole 31, and the stopper 32 can be moved up and down by operation from the hull X side. A hemispherical hole 34 with an enlarged diameter is connected above the hole 30. On the other hand, the buoy Z has a rod-shaped stud eye 35 erected on its head.
The stud eye 35 is formed with a tapered large diameter head 36, and when the stud eye 35 passes through the hole 30 and the tapered large diameter head 36 is inserted into the hemispherical hole 34, the stopper 32 moves downward. If it is lowered, it will not fall out.

Next, the mooring method will be explained.

During navigation etc., as shown in Figure 1, the mooring arm 2
is stored in the recess 1, and the spherical bow 3 is attached to the hull X side to be used as part of the hull structure. When mooring, the motor 24 is rotated to rotate the pinion gear 25 and rack hinge 23 to lift the mooring arm 2 toward the front of the ship. Then, move the hull X so that the bulbous bow 3 is located directly above the buoy Z and stop.
The motor 24 is reversed (or the motor 2
4 is stopped and the bulbous bow 3 is gradually lowered (by its own weight), and the stud eye 35 is inserted into the hole 30 of the bulbous bow 3. At this time, the stopper 32 is
3 may be raised to the upper side, but if it is loosely fitted as it is, it will be pushed upward by the tapered head 36 and will move downward by its own weight once the head 36 penetrates.

Stopper 3 with stud eye 35 penetrating
2 is at the bottom, this stud eye 35 will not come out, thereby completing the engagement and mooring. When unmooring, the electromagnet 33 is energized, the stopper 32 is raised, and the bulbous bow 3 is pulled out from the stud eye 35.

(Effects of the invention) As explained above, according to the mooring device of the present invention, mooring is possible only by operation from the hull side without the need for the help of a support vessel, so it has the effect of promoting automation and simplification of ships. There is.
