Impacts of surface waves of the sea and the bottom of ship are absorbed by the accumulator, and pitching and rolling are reduced by the support 4.

Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a passenger ship equipped with a passenger cabin, and more specifically, the present invention relates to a passenger ship equipped with a cabin, and more specifically, the cabin is made independent from the ship's hull so that the cabin is always stable despite the movement of the ship. The present invention relates to a passenger ship that is maintained in a fixed state, and is particularly suitable for application to a high-speed ship (boat).

(b) Conventional technology A horizontal support structure that stabilizes the cabin relative to the ship's hull has never been seen on high-speed ships such as planing types, with the exception of large displacement passenger ships.

(c) Problems to be solved by the invention A planing-type high-speed ship (boat) that runs on the sea surface runs on surface waves with short wavelengths, so there is a difference between surface waves (for example, ripples) and the bottom of the ship. and 7, and this impact is proportional to the speed of the ship and is not desirable.

On the other hand, when a ship runs on waves with long wavelengths, rolling and pitching movements occur, especially in high-speed ships, because the period of the waveform becomes short. , and its intensity increased.

B) Means for Solving the Problems Therefore, in the present invention, the cabin and the hull are separated, and a shock absorbing device is provided which alleviates the effect of impactful acceleration between the hull and the wave surface, and a buffer device which alleviates the effects of rolling and pitching of the hull. A supporting device equipped with a buffer device that absorbs the impact and responds to the action of the impact acceleration is placed between the hull and the passenger cabin to stably hold the passenger cabin on the hull. is a hydraulic support cylinder (ram cylinder 9) that supports the passenger cabin, and compressed gas in the accumulator connected to it to cushion the impact on the passenger cabin.The support device supports pitching and rolling of the hull, and supports The oil pressure in the drive cylinder of the ship is automatically increased or decreased based on computer instructions to prevent vibrations of the ship caused by long wavelength waves from being transmitted to the cabin.

In addition, a buffer device is interposed between the drive cylinder and the passenger compartment so that the impact of the aforementioned acceleration is not transmitted to the passenger compartment via the drive cylinder, and the impact of the acceleration is prevented from reaching the passenger compartment. . This will be explained with reference to an example.

(e) Embodiment FIGS. 1, 2, and 3 show a side view, a plan view, and a front view of the passenger ship of the present invention, and show the arrangement of the above-mentioned shock absorbers and support devices, and 1 indicates the hull; 2 is a passenger cabin supported on the hull 1 separately and independently from the hull 1; 3 is a shock absorber, which supports the passenger cabin 2 at six points in parallel with a support device 4 to be described later;
As shown in FIG. 4, the shock absorber 6 consists of a support cylinder (ram cylinder) 5 and an accumulator 6, and supports the passenger compartment 2 via a piston 8 and a piston rod 8a by the gas pressure of N2 gas 7 in the accumulator 6. Considering rolling and pitching of the hull 1, a support shaft 9 is installed in the support cylinder 5, and a support shaft 1 is installed in the cabin 2.
0 is set.

Next, the support device 4 supports the drive cylinder (servo cylinder) 11 on the support shaft 12, similar to the support cylinder 5 described above, and connects the tip of the piston rod 13a of the piston 13, which moves up and down by hydraulic pressure, to the hull 2. It is connected via a pin 16 to a sliding shaft 15 that is loosely fitted into a sliding groove 14 on the side, and the sliding shaft 15 is provided with coil springs 17a at the top and bottom.

By placing the i7b, the passenger compartment 2
It is connected to. Reference numeral 18 denotes a shock absorber, which constitutes a buffer device 19 for the drive cylinder that prevents the aforementioned acceleration of the hull 1, that is, the vibration caused by the impact between the wave surface and the hull from being transmitted to the cabin 2 via the drive cylinder 11. It is.

Next, to explain the buffer device shown in more detail in FIG. 5, 20 is a guide, 21 is a slide, and the drive cylinder 11 follows all movements of the ship, and is installed in the ship and the cabin. The structure is designed to respond sensitively to feedback signals from sensors in each building, allowing it to expand and contract.

In this buffer device, the function of the shock absorber 18 is extremely important in order to obtain a high degree of stability of the passenger compartment. That is, it is necessary to be able to cope with all kinds of natural conditions within the range in which the vehicle can travel, and at the same time, it is necessary to perform sufficient control over changes in the number of passengers. However, it is difficult to cover all conditions only with the spring constants of the coil springs 17a and 17b once set.

This is because it is impossible to replace the spring frequently.

Therefore, the shock absorber 18 was interposed, its orifice was made variable, and the damping force was changed by adjusting the orifice manually or automatically depending on the conditions using an external control signal, and the coil springs 17a and 17b were replaced. A variable orifice type shock absorber 18a shown in FIG. 6, which achieves the same effect, adjusts the amount of oil to the cylinder 23 using a proportional electromagnetic ori-Swiss valve 22, as shown in FIG. This shows a proportional electromagnetic orifice valve, in which the output from the power amplifier is introduced into an electromagnetic coil 25 via a lead wire 24, and the coil 25 is energized to move the plunger 26 while opposing the elasticity of the spring 27. The tapered spool 28 is moved relative to the orifice valve seat 29 to form a variable orifice, and the damping force of the shock absorber 18 is adjusted. 30 is a slide bearing.

In FIG. 1, 31 is a tank unit, 32 is a valve stand, 66 is an accumulator stand, 64 is a power unit, 65 is various motion detection devices, and 36 is an operation control panel.

(f) Function In the passenger ship of the present invention having the above-described configuration, the shock absorber 6 absorbs small-scale impacts between ocean surface waves and the bottom of the ship by the gas 7 of the accumulator B, and prevents wave motion to the cabin 2. At the same time, the motion of the hull 1, that is, pitching and rolling, is detected by the detection device 35, and the support devices 4 on the front, rear, left, and right sides are automatically activated to increase or decrease the oil in each of the drive cylinders 11 so that the cabin 2 remains horizontal. Based on the combined pitching and rolling operations, the drive cylinder 11 is quickly adjusted to prevent the cabin from shaking.

In particular, the buffer device 19 incorporated in the support station is equipped with a coil spring 17a h 17b and a shock absorber 18, and since the shock absorber 18 is of a variable orifice type, it can be adjusted manually or automatically under any conditions. It is now possible to form the orifice in a corresponding manner and to keep it in a very stable state even with changes in the weight of the passenger compartment.

(g) Effects of the Invention In order to limit the effects of the invention, in the passenger ship of the present invention, especially in a planing type high-speed ship, the shock between the sea wave surface and the bottom of the ship is absorbed by the shock absorber B that supports the cabin 2, and the support device 4, the attitude angle of the hull 1 is detected in response to the pitching and rolling action of each chamber 2 using an angle sensor, a speedometer for vertical movement, etc., and this is processed by a computer and commanded to each of the drive cylinders 11. Since it gives a level of the cabin 2 and maintains the levelness of the cabin 2, it has an excellent feature that can correspond to as many natural and artificial conditions as possible.

In particular, by providing a buffer device 19 in the support device 4, the vibrations of the drive cylinder 11 on the hull 1 side and the coil spring 17a can be reduced.

The shock absorber 18 has the function of keeping the passenger compartment level while absorbing even the slight vibrations caused by the shock absorber 17b. The ship is highly stabilized and can function as an excellent high-speed passenger ship.
