Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a high-speed boat suitable for passenger use and patrol use.

[Conventional technology]

As a conventional high-speed boat, there is one as shown in FIG. 3, in which an upper hull 1B having a cabin 2 and a cockpit 3 is provided above a main hull 1A.
This upper hull 1B includes a plurality of first shock absorbers 10.
a, 10b and these buffer devices 10a, 10
The first hydraulic cylinder device 11a, 1 connected to b
1b (more precisely, the first shock absorbers 10a, 10b are connected to the piston-equipped rods of the first hydraulic cylinder devices 11a, 11b).
It is supported by A so that it can rotate and move up and down.

Further, the passenger compartment 2 is provided with an attitude angle detector 9, and a detection signal from this attitude angle detector 9 is inputted to a control calculation device 12. The control calculation device 12 outputs a control signal that minimizes the oscillation detected by the attitude angle detector 9 to, for example, the electromagnetic valves 14a and 14b (and to the hydraulic pump 13 if necessary). The hydraulic oil from the hydraulic pump 13 is supplied to the valve 14.
The first hydraulic cylinder device 11 via a, 14b
a, 11b, and can reduce the oscillation of the upper hull 1B.

Incidentally, the outline of such a vibration suppression control system for the upper hull 1B is shown in FIG. 4.

Further, the main hull 1A is propelled by a propeller 5 provided at its rear end and steered by a rudder 4, as shown in FIG. The propeller 5 is driven by an engine (not shown) in the main hull 1A via a propeller shaft 6 rotatably supported on the main hull 1A by a shaft bracket 7.

Note that the engine and rudder 4 are operated from the cockpit 3.

In this way, according to such a high-speed boat, even during waves, the main hull 1 can absorb the vibrations of the cabin 2 and cockpit 3.
It can be made extremely small compared to A, thereby providing extremely good riding comfort.

Note that the reference numeral 8 in FIG. 3 indicates the waterline.

[Problem that the invention attempts to solve]

However, in such conventional high-speed boats,
Since the upper hull 1B is configured separately from the main hull 1A and these move independently, the conditions of the main hull 1A and the engines installed within the main hull 1A should be especially investigated during navigation. for,
There is a problem in that when it becomes necessary for a crew member to transfer from the upper hull 1B to the main hull 1A, this transfer is difficult.

The present invention aims to solve these problems by making it possible to easily and safely transfer between the upper hull and the main hull during navigation.
The purpose is to provide high-speed boats.

[Means for solving problems]

Therefore, the high-speed boat of the present invention includes an upper hull having a cockpit, and a first shock absorber and a first hydraulic actuator connected to the first shock absorber to support the upper hull so as to be rotatable and vertically movable. An intermediate member for transferring between the upper hull and the main hull is provided independently of and adjacent to the upper hull, and the intermediate member is driven separately from the upper hull. Accordingly, the intermediate member is supported by the main hull via a second shock absorber and a second hydraulic actuator connected to the second shock absorber.

[Effect]

With the above configuration, for example, in order to transfer from the upper hull to the main hull, the intermediate member is first moved in synchronization with the upper hull, and after the crew member has transferred to the intermediate member, the intermediate member is transferred to the main hull. Make it move in the same way as the hull.

〔Example〕

Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. Figures 1 and 2 show a high-speed boat as an embodiment of the present invention. The figure is a top view of the same, and in FIGS. 1 and 2, the same reference numerals as in FIG. 3 indicate almost the same parts.

Also in this embodiment, as shown in FIGS. 1 and 2, an upper hull 1B having a cabin 2 and a cockpit 3 is used.
is rotated and vertically applied to the main hull 1A via a plurality of first shock absorbers 10a, 10b and first hydraulic cylinder devices 11a, 11b as first hydraulic actuators connected to these first shock absorbers 10a, 10b. Supported for free movement.

Further, the passenger compartment 2 is provided with an attitude angle detector 9, and a control signal is sent from the control calculation device 12 to the electromagnetic valves 14a, 14b to minimize the oscillation detected by the attitude angle detector 9.
By outputting the signal to the hydraulic pump 13 (if necessary), the first hydraulic cylinder devices 11a and 11b are operated to reduce the oscillation of the upper hull 1B.

Although the attitude angle detector 9, the control calculation device 12, the electromagnetic valves 14a and 14b, and the hydraulic pump 13 are not shown in FIG. 1, these members are included in the attitude angle detector 9 shown in FIG. , control calculation device 12, electromagnetic valves 14a, 14b,
Corresponds to the hydraulic pump 13.

Further, the outline of the oscillation suppression control system for the upper hull 1B is the same as that shown in FIG. 4 described above.

Furthermore, the main hull 1A is propelled by a propeller 5 provided at its rear end and steered by a rudder 4, as shown in FIG. 3.

By the way, a small compartment member 15 as an intermediate member for transfer between the upper hull and the main hull is provided independently of the upper hull 1B and adjacent to the upper hull 1B at a side portion of the main hull 1A near the center of hull motion. It is being

This small section member 15 includes a plurality of second shock absorbers 10a', 10b' and a second hydraulic cylinder device 11 as a second hydraulic actuator connected to these second shock absorbers 10a', 10b'.
a', 11b' (to be exact, the second shock absorbers 10a', 10
b' is connected to the piston rod of the second hydraulic cylinder device 11a', 11b'. ) is rotatably and vertically movably supported by the main hull 1A.

Thereby, the small section member 15 can be driven separately from the upper hull 1B.

Furthermore, the second hydraulic cylinder devices 11a', 11
b' is an electromagnetic valve (not shown) interposed between the hydraulic pump 13' and each of the second hydraulic cylinder devices 11a' and 11b' (as required). If so, hydraulic pump 13')
It is designed to be activated by receiving and operating the system.

Note that the control arithmetic unit and the hydraulic pump may also be used for the upper hull.

Further, the reference numeral 16 in FIG. 2 indicates the hull centerline.

With the above configuration, for example, the main hull 1A during navigation.
In order to check the condition of the engine and the engine installed in it, the crew moved from the upper hull 1B to the main hull 1.
Considering the case of transferring to A, first, the small compartment member 15 is moved in synchronization with the upper hull 1B by performing the same control as the movable parts (upper hull 1B) such as the cabin 2 and the cockpit 3. . During such a synchronized movement, the crew member only needs to transfer from the upper hull 1B to the subdivision member 15.

After the transfer to the small compartment member 15 in this way, the above control is stopped, thereby causing the small compartment member 15 to move integrally with the main hull 1A.

After that, the crew member only has to transfer from the small compartment member 15 to the main hull 1A.

Furthermore, when transferring from the main hull 1A to the upper hull 1B, the operation described above may be reversed.

By the way, switching between moving the subdivision member 15 integrally with the upper hull 1B or integrally with the main hull 1A is performed automatically or manually. In the case of automatic transfer, the transfer direction detection means detects whether the transfer is from the main hull 1A to the upper hull 1B or vice versa, the switching timing detection means detects whether the crew member is transferred to the small compartment member 15, etc. In short, in the case of manual detection, a manual switch is used in place of the above-mentioned detection means.

In this way, the upper hull 1B and the main hull 1A can be transferred easily and safely.

It should be noted that if the small section member 15 is provided near the center of the ship's motion as described above, the stroke of the second hydraulic cylinder devices 11a', 11b' can be made smaller and the structure can be simplified, but 1
As long as it is adjacent to B, it may be installed in any other suitable location.

[Effect of idea]

As described in detail above, the high-speed boat of the present invention includes an upper hull having a cockpit, and the upper hull is rotated via a first shock absorber and a first hydraulic actuator connected to the first shock absorber. and a main hull that supports vertically movably, an intermediate member for transferring between the upper hull and the main hull is provided independently of the upper hull and adjacent to the upper hull, and the intermediate member is attached to the upper hull. The intermediate member is driven separately from the second shock absorber and the second shock absorber.
With a simple structure supported by the main hull via a second hydraulic actuator connected to a shock absorber, there is an advantage that mutual transfer between the upper hull and the main hull can be easily and safely performed.
