Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mooring device for a ship, and more particularly to a mooring device particularly suitable for mooring a small ship.

When mooring a small vessel to a quay, conventionally, one person disembarks first with either the stern or the bow attached to the quay, and this person receives a rope thrown from the vessel and hangs it on a bit on the quay. Alternatively, one person waits on the quay side and receives the rope thrown from the ship. With conventional mooring methods, the work requires manpower, and the hull of the ship may collide with the quay wall and be damaged during the work or mooring. In order to prevent damage to the ship's hull, rubber air fenders are installed between the ship's hull and the quay, but in this case, the gap between the ship's hull and the quay becomes wide, and this has the disadvantage that people cannot disembark the ship. be.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ship mooring device that is robust and has a simple structure that solves the above problems.

The ship mooring device according to the present invention has an opening on the ship side, and has an opening inside the ship so that the base end of the main cylinder extending in the width direction of the ship can rotate around a vertical axis and a horizontal axis in the bow and stern direction. The tip of this cylinder is attached to the hull slightly inside the opening on the ship's side via the cylinder for moving the main cylinder in the fore and stern direction and the cylinder for moving the main cylinder in the vertical direction, and is attached to the outside of the hull through the opening on the ship's side. A fender that fits into the opening when the rod retracts is attached to the tip of the rod of the main cylinder that can be advanced, and a plurality of connecting pins are provided on the outer periphery of the fender that are moved forward and backward by a cylinder for advancing and retracting the connecting pins. A concave portion is provided on the inner peripheral surface into which the connecting pin of the fender can enter, and an operation panel is used to remotely control the main cylinder, the cylinder for moving the main cylinder in the bow and stern direction, the cylinder for moving the main cylinder in the vertical direction, and the cylinder for advancing and retracting the connecting pin. is installed on the hull of the ship, and the mooring floating body, which can adjust its water intake, is attached to the quay and floats on the water surface so that it can move freely in the vertical direction but hardly move horizontally. A fender recess into which the fender fits is provided on the side surface, and a connecting pin recess into which the fender's connecting pin can enter is provided on the inner peripheral surface of the fender recess.

The fender was connected to the mooring floating body by advancing the rod of the main cylinder from the hull and fitting the fender into the fender recess of the mooring floating body, and by advancing the connecting pin of the fender and fitting it into the connecting pin recess of the fender recess. Later, by retracting the rods and bringing the hull closer to the quay, the vessel can be berthed.Conversely, after extending the rods and moving the hull a certain distance from the quay, the connecting pins are retracted and the fender can be moored. By retracting the rod while separated from the floating body, the ship can be moved away from the shore. These operations can be easily performed by one person from the ship by operating the operation panel. In addition, by moving the rod forward and backward with the fender connected to the mooring floating body, the distance between the hull and the quay can be adjusted appropriately, and this distance can be maintained almost constant by the rod.
There is no risk of the hull colliding with the quay while moored. Furthermore, even when the hull approaches the quay, if the rod is advanced from the hull to a certain extent, only the fender will hit the quay, and there is no risk of the hull colliding with the quay. Furthermore, the height (vertical position) of the ship's rod
Even if the mooring float changes, the fender can always be connected to the fender recess of the mooring float by adjusting the water intake of the mooring float, and if the height relationship between the mooring float and the rod is matched at the start of mooring. Even if the tide level changes during mooring, the mooring floating body and rod both follow the tide level and move up and down, so their height relationship will not change.

According to the ship mooring device of the present invention, as described above, the ship mooring operation does not require manpower and the ship can be safely moored. Since the fender is connected to the fender recess provided on the sea side side of the water-adjustable mooring floating body floating on the water surface of the quay, the main cylinder to which the fender is attached needs to be moved significantly in the vertical direction. Also, since the base end of the main cylinder is attached to the hull, the main cylinder alone can receive the force. Therefore, the structure is simple and the strength is high. Furthermore, since the fender is attached to the tip of the rod extending outward from the ship's side, the fender can prevent the ship's body from colliding with the quay.

Embodiments of the present invention will be described below with reference to the drawings.
