Abstract

PURPOSE:To provide an emergency collision preventing device for a ship which is caused to effect turning-around of a ship hull occasioned by lateral movement and apply brake through a simple mechanical means by properly preventing the occurrence of collision when a ship under sailing is brought into a situation that collision with other ship is predictable. CONSTITUTION:Each of two ship's sides is provided with a working plate 2 the rear end of which is pivotally mounted on a ship hull 1 and revolvable to the outside, a ship hull recessed part 1a containing the working plate 2 to form a ship shape in a well-ordered shape, and a working plate holding means 5 capable of releasably holding the working plate 2 in the ship hull recessed part 1a. Each of conduits 3 through which external water dammed up at the front of the working plate 2 during revolving operation of the operating plate 2 is guided to the opposite ship's side is disposed to a portion ranging from an opening 1b formed in the ship hull recessed part 1a to an opening 1c formed in the ship hull outer board of the opposite ship's side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency collision for ships, which is capable of appropriately avoiding the collision when a ship in transit falls into an emergency situation where a collision with another ship is predicted. Regarding the avoidance device.

[0002]

2. Description of the Related Art As a conventional means for preventing collision of a ship, the main engine is rotated in the reverse direction or the blade angle of a variable pitch propeller is set to the reverse side to decelerate the ship. There was also an emergency measure to prevent the collision by turning the hull to the left or right to turn the hull.

[0003]

By the way, the conventional means as described above requires a power source for both the reverse rotation of the main engine, the blade angle control of the variable pitch propeller, and the emergency steering, and can be implemented in the case of a power failure. There is a problem that it disappears.

The present invention is intended to solve such a problem, and makes it possible for a hull in motion to turn or brake with lateral movement by a simple mechanical means. It is an object of the present invention to provide a marine emergency collision avoidance device capable of performing the above.

[0005]

In order to achieve the above-mentioned object, the marine vessel emergency collision avoidance device according to the present invention is provided with an operating plate which is pivotally attached to both sides of the ship and has its rear end pivotally attached to the hull. A hull recess for accommodating the actuating plate to adjust the ship shape, and actuating plate holding means capable of releasably holding the actuating plate in the hull recess. Is characterized in that a water conduit for guiding the outside water, which is stopped at the front surface of the ship, to the port side is provided from the opening provided in the recess of the hull to the opening in the outer plate of the ship on the port side.

[0006]

In the emergency collision avoidance system for a ship of the present invention described above, in the case of an emergency such as when another ship is approaching from the front during navigation, one of the operating plates on both sides of the port is selected. An operation for releasing the holding means of the operating plate is performed.

As a result, the actuating plate automatically turns around the pivotal attachment portion to the hull and is opened outward, so that the actuating plate is applied to the hull by an external force associated with the action of damming the outside water. A turning moment is generated and the hull is turned.

At the same time, a part of the external water dammed by the operating plate is discharged to the outside of the port through the water conduit provided from the recess of the hull for storing the operating plate to the opening of the port. As a result, the reaction force causes the hull to move laterally toward the turning side.

In this way, the turning of the hull and the lateral movement to the turning side can accurately avoid a collision with another ship.

Further, the actuating plates on both sides of the port can be simultaneously swung to actuate a braking action that suppresses the forward movement of the hull.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A ship emergency collision avoidance device as an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a ship equipped with the device, and FIG. ..

As shown in FIGS. 1 and 2, operating plates 2 each having a rear end pivoted by a hinge 6 are provided on both port sides of the hull 1 near the bow so that they can be swung outward. The operating plate 2 is normally stored in the hull recess 1a so that the ship shape is adjusted.

A link member 4 having a joint in the middle portion
Is mounted between the inner portion of the working plate 2 and the hull recess 1a so as to be foldable, and thereby the limit of the turning angle of the working plate 2 is set. Board 2
Other appropriate stoppers may be provided as a means for restricting the turning.

In a state where the operating plate 2 is stored in the hull recess 1a, the operating plate 2 serves as a holding means for the actuating plate 2 from the inside of the ship with respect to the hull recess 1a so that the operating plate 2 does not open unintentionally while the ship is traveling. A projecting and retractable stop pin 5 is provided so as to be engageable with the tip end portion of the operating plate 2.

In the forward state of the hull 1, the water pressure in the hull recess 1a is higher than the water pressure on the outer surface of the working plate 2 due to the action of the water flow along the outer surface of the working plate 2. Although the working plate 2 is automatically opened by releasing the stop pin 5, a driving means 7 such as a fluid pressure cylinder as shown in FIG. May be.

A tubular water conduit 3 is provided from an opening 1b provided in the hull recess 1a so that a part of the external water, which is retained on the front surface of the operating plate 2 when the operating plates 2 are swung, can be guided to the opposite port side. It is provided up to the opening 1c in the outer plate of the ship on the opposite side, and each water conduit 3 is provided with a valve 3a.

With the above-mentioned structure, in the case of an emergency in which another ship is approaching from the front during navigation of the ship, one of the operating plates 2 on both sides of the port is selected to perform the same operation. The operation of releasing the stop pin 5 as a holding means of the plate 2 is performed by remote control. Thereby, the operating plate 2
Automatically pivots around the hinge 6 and opens outward, so that a turning moment of the hull 1 is generated by the external force of the actuating plate 2 due to the external water damming action, and the turning of the hull 1 occurs. It will be done.

At the same time, a part of the external water dammed by the actuating plate 2 goes to the outer side of the port side through the water conduit 3 provided from the opening 1b of the hull recess 1a to the port side opening 1c. As it is discharged, the reaction force causes the hull 1 to move laterally toward the turning side.

In this way, by the turning of the hull 1 and the lateral movement to the turning side, a collision with another ship can be accurately avoided.

Further, the actuating plates 2 on both sides of the port can be simultaneously swung to actuate a braking action for suppressing the forward movement of the hull 1.

In this case, it is desirable to close each valve 3a.

[0022]

As described in detail above, according to the marine emergency collision avoidance device of the present invention, the hull in the course of traveling is turned or braked by lateral movement by a simple mechanical means. Therefore, in an emergency where a collision with drift ice or another ship is predicted, the collision can be accurately avoided.
