Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marine vessel that does not swing even in stormy weather and can sail stably.

[0002]

2. Description of the Related Art Conventionally, there are ships which can limit the rocking during navigation, but the main means are the use of outboard fins and the use of outboard floats. As you can see, there is no one that uses a submerged float.

[0003]

2. Description of the Related Art Ships sail on the surface of the water, and the mainstream is to float the hull on the surface of the water and maintain its position by its buoyancy. However, when the waves are high, such as during stormy weather, the water surface position changes due to the waves, and the hull sways. Conventionally, various means have been adopted to prevent the swinging. For example, there is a type in which a fin is provided outside a boat and the swinging is reduced by the fin. However, while this helps reduce rocking, it does not result in rocking. In addition, there is a method of preventing roll by using an outboard float. In this method, since the body becomes a twin body, the roll is alleviated. However, with any of the above means, the hull and the float are located on the surface of the water, so that it is impossible to completely prevent the sway. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems relating to the conventional rocking prevention means, and achieves the object by submerging the float.

[0004]

As a means for solving the problems, the present invention achieves the object by obtaining buoyancy in a submerged underwater hull and supplying and exhausting gas to and from a submerged underwater hull. In other words, in a ship formed by connecting a watercraft hull located above the water and an underwater hull located underwater by a support, a water inlet is provided at a suitable position on a side surface of the underwater hull and an air intake pipe is provided at a suitable upper portion via a valve. The gas from the gas supply means provided in the hull can be supplied and exhausted from the air supply pipe to the underwater hull, and by controlling the air supply and exhaust, the buoyancy of the underwater hull is adjusted to stabilize the hull position during navigation. Is possible. The present invention is a non-swinging boat having the above configuration.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to use the present invention, when the hull is positioned above water and a valve is opened, air in an air chamber is exhausted to the atmosphere, and water enters through a water inlet. The valve is closed at an appropriate hull position to determine the vertical position of the hull. At this time, the underwater hull is located underwater, and the overwater hull is located above water. In this state, the ship sails by turning the screw, but the sea surface is located in the middle of the column and does not contact both hulls.
And even when the waves are large, such as in stormy weather, the underwater hull is always underwater. And the wave-making resistance due to this is also reduced. In other words, the hull of a general ship is located in contact with the sea surface, so that the hull swings due to sea level changes. However, in the present invention, the buoyancy main body is submerged, and a stable posture can be maintained. Further, according to the present invention, injection and exhaust are performed on the underwater hull, and the hull is provided with a water inlet. Therefore, when the air pressure in the hull rises due to air injection, seawater is discharged from the water inlet, and seawater conversely invades by the exhaust. Therefore, the buoyancy of the underwater hull can be adjusted, the vertical position can be set and adjusted relative to the sea surface during navigation, and the hull can be stabilized.

[0006]

Embodiments of the present invention will be described below. In the drawing, reference numeral 1 denotes a watercraft hull, and 2 denotes a substantially columnar underwater hull, which is provided at a lower portion of the watercraft hull by a column 3. The underwater hull is partitioned into three chambers, and the center is used as an air chamber 4. A water inlet 5 is provided on the lower surface of the air chamber,
Further, a depth sensor 6 is attached to an appropriate place in the room. A motor 7 is provided in the rear compartment of the hull, and a screw 8 located outside the hull is connected. An engine 9 and a generator 10 connected to the engine are provided inside the watercraft hull. The electric power generated by this generator is supplied to the adjacent air compressor 11 and the motor. Pressurized air from the compressor is supplied to an air supply pipe 12 whose end is located above the air chamber. An exhaust pipe 13 is located adjacent to the air pipe, and the other end is connected to a solenoid valve 14 as shown in FIG. In order to control the operation of the compressor and the solenoid valve, a control device 15 having an arithmetic circuit is provided, and signals from the above-mentioned depth sensor and a horizontal level sensor 16 arranged at a proper position on the ship are supplied to the control device. Is done. The foremost part of the underwater hull is a clear cover 17 made of a transparent material.
8 are installed in close proximity.

Although the main function of the present invention has been described above, in the present embodiment, the air supply and the exhaust are configured by separate pipes. Further, a motor was used as a drive source of the screw, and a method of supplying power from a generator rotated by an engine to the motor was used. This electric power is also supplied to the air compressor to supply pressurized air to the air chamber. As another method, the screw may be directly rotated by an engine instead of the motor. In this case, outside air is taken in from the water hull and supplied to the engine via the struts. In this example, the depth and the hull inclination are sensed by using the respective sensors, the signals are transmitted to a control device for calculation, and the compressor and the solenoid valve are controlled by the transmission signals. In other words, unlike ordinary ships, the underwater hull moves up and down with a slight change in buoyancy, so in order to control this lifting, the above means senses the vertical position of the hull and enables fine adjustment of buoyancy. is there.
The depth sensor in this example uses a pressure sensing type,
It may be provided on any of the underwater hulls, and level sensors for horizontal sensing are provided at appropriate places on the surface of the water hull, and the signals from these sensors are processed to achieve the purpose. The same applies to the case where a depth sensor is provided on each underwater hull without using a level sensor.

Further, in this embodiment, the front end of the underwater hull is formed of a transparent body and the search light is provided inside, so that underwater exploration can be easily performed. As described above, according to the present invention, it is possible to navigate while maintaining a stable posture without swinging even in a stormy weather. Applications of the present invention include salvage rescue and work in rough weather. As shown by the imaginary line in FIG. 4, various works can be easily performed by providing a bucket elevating mechanism using a winch. Since the distance between the underwater hull and the sea surface can be freely set, a state more suitable for work can be obtained. As another application, underwater tourism is assumed. This makes the underwater hull transparent and makes it possible to entertain tourists and enjoy the underwater environment. As described above, according to the present invention, it is possible to obtain a ship that can be used in various ways that cannot be obtained with a conventional ship.

[0009]

According to the present invention, since buoyancy can be generated by the underwater hull and buoyancy can be adjusted by injection and exhaust, it is possible to sail while maintaining a stable attitude regardless of the increase in waves due to the weather. And a useful ship that can greatly contribute to offshore work and the like.
