本発明は、船体の向きの変更又は船体の横方向移動を緊
急に行う時に用いて好適な船舶の緊急回頭装置に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an emergency turning device for a ship suitable for use when changing the direction of a ship or moving the ship in a lateral direction in an emergency.
従来船体の向きの変更又は船体の横方向への並行移動を
行うだめの装置としてサイドスラスタがある。サイドス
ラスタは通常船首、船尾部の吃水面以下に船体を横切っ
て海水の流出入をにより船体の右舷側若しくは左舷側に
海水を吐出し、その反力により船体の姿勢制御、移動を
行なわせるものである。Conventionally, there is a side thruster as a device for changing the direction of a ship or moving the ship in parallel in the lateral direction. A side thruster is a device that discharges seawater to the starboard or port side of the ship by flowing in and out of seawater across the ship below the water level at the bow and stern, and uses the reaction force to control the ship's attitude and move it. It is.
しかし、従来のサイドスラスタ−は、主として船体速度
が非常に低いときに船体のむきをかえ、まだは平行移動
をさすことを目的としだものであり、ある程度の船体速
度を有する場合の衝突や乗揚げをさけるには力のたりな
いものだった。However, conventional side thrusters are primarily designed to change the direction of the ship when the ship's speed is very low, and still cause parallel movement. I didn't have enough strength to avoid frying.
他方、海峡、水道等の船舶交通容量が増して来ており、
このため衝突・障害物への乗揚げ等の海難事故を防止す
るために船舶の旋回停止性能を向上させることが重要と
なって来つつある。On the other hand, the capacity of ship traffic in straits, waterways, etc. is increasing.
For this reason, it is becoming important to improve the turning and stopping performance of ships in order to prevent marine accidents such as collisions and running aground on obstacles.
さらに９港湾・乗船場等においても船舶の輻幀のだめに
衝突等の防止を図るために船舶の急速旋回、停止機能を
向上させることが重要となって来ている。In addition, it has become important to improve the rapid turning and stopping functions of ships at nine ports and boarding areas in order to prevent ships from colliding with each other due to congestion.
このような船舶の急速旋回を行うために前述のインペラ
によるサイドスラスタ−などは、この目的のだめの好適
装置であるが、これらは高価でもあり、また使用時間も
みじかいのでサイドスラスタ−を装備している船舶は少
い。壕だ上述のような急速旋回を行うために充分な力を
そなえるように主機に近い圧力のサイドスラスタ−をつ
けることも考えられるが、経済的負担が大きくなり到底
現実的でない。The impeller-based side thruster mentioned above is a suitable device for this purpose in order to make rapid turns in such ships, but these are expensive and the time for use is short, so it is not recommended to equip the ship with a side thruster. There are few ships. It may be possible to install side thrusters with a pressure close to that of the main engine in order to provide sufficient power to perform the rapid turns described above, but this would be an economical burden and would be completely impractical.

水管とからなることを特徴としている。The purpose of the present invention is to provide an emergency turning device for a ship that enables rapid turning or parallel movement of a ship with a relatively simple device, in order to solve the problems of the conventional device described above and to cope with actual situations. A high-pressure tank installed in the tank, a seawater pump to send seawater to the high-pressure tank, an air compressor to pressurize the seawater sent to the high-pressure tank, and a high-pressure tank installed on both sides of the ship to discharge seawater from the high-pressure tank overboard. It is characterized by a seawater pipe with a valve that is led from a high-pressure tank to a seawater flow hole.
〔作 用〕 上述の本発明の船舶の緊急回頭装置によれば。[For production] According to the above-mentioned emergency turning device for a ship of the present invention.
海水管に設けられたバルブの操作のみにより船舶を希望

とができる。The vessel can be turned or moved in parallel in a desired direction in a short period of time simply by operating a valve installed in the seawater pipe.

Fig. 1 is a side view of a ship equipped with the device of the present invention at the bow, and Fig. 2 is a view taken in the direction of the arrow in Fig. 1. ■
-H is a cross-sectional view along H. In these diagrams, 1 is a high-pressure tank that can handle high pressure, 2 is a seawater pump, 8 and 4 are valves, and 5

一方を必要な断面積Ｓだけ開閉することができる。7 is compressed air that is pressurized by the air compressor 5 and sent into the high-pressure tank 1, and its pressure is P. 8/'i The seawater pump 2 pumps the seawater into the high-pressure tank 2 from the outside, and the stored seawater has a density of d. 9 and 10 are high pressure tank 1
A valve is installed in the middle of a seawater pipe 12 that connects the lower part of the high-pressure tank 1 and the seawater outflow holes 11 provided on both sides to discharge the seawater 8 inside the ship to the outside. Either one can be opened or closed by the required cross-sectional area S.

。水中にふきだすときは。When opening valve 9 or 10 and spewing seawater 8 into the air,
From Bernoulli's theorem, the speed V is P-Po-
Also known as d - V 2/2. Here Po is the atmospheric pressure. On the other hand, the reaction force exerted on the hull due to the discharge of seawater 8 overboard, that is, the lateral thrust, is equal to the product of the mass of the outflowing seawater and its speed, d-8・y2, which is the same as above. Using the formula, it becomes 2(P'-Po)S. When spraying into the water.

間の推力かえられる。海水８の放出による圧縮空気７の
圧力低下にともなう推力の減少は。If the water resistance is extremely large, it is due to static pressure (p-Po)
S, and when seawater 8 is discharged to the outside of the ship near the water level 13, the thrust is generally changed to an intermediate value between 2(P-Po)S and (P-Po)S. The thrust decreases as the pressure of compressed air 7 decreases due to the release of seawater 8.
圧縮空気７の圧縮比を海水８と圧縮空気７の容積比より
充分大きくすることにより、充分小さくすることができ
る。By making the compression ratio of compressed air 7 sufficiently larger than the volume ratio of seawater 8 and compressed air 7, it can be made sufficiently small.

ることが出来るものである。In this way, seawater 8 is spouted out to either the left or right when the boat comes to a sudden stop, when the direction of travel becomes unstable due to reversing, or when the rudder becomes difficult to steer due to deceleration. This allows the ship to be maneuvered by easily obtaining a large heading perpendicular to the direction of travel in a relatively short period of time. It is also possible to reduce the output and generate a small thrust for a relatively long period of time to turn the ship. Although this embodiment shows an example in which the device of the present invention is installed at the bow of the ship, it can also be installed at the stern, both sides, or the center of the ship depending on the purpose of installation. It is.

る。The lower part of the high-pressure tank is charged with seawater and the upper part is charged with compressed air using an air compressor.Then, when an emergency situation such as a collision or grounding is expected, the vessel is put in reverse and the vessel is moved in an unstable direction. When the turning force from the rudder is insufficient, or when the vessel is maneuvered in a narrow place, the extremely simple structure allows the seawater to be spewed out using the energy of the compressed air by opening either the left or right valve. It is possible to control the direction of the ship by obtaining the lateral thrust necessary for turning or parallel movement of the ship.
