[0001]

The present invention relates to an underwater observation boat.

[0002]

2. Description of the Related Art There is already a double-hull type ship in which two or three drainage bodies are arranged in parallel in the direction of travel, and the plurality of drainage bodies are integrally connected via a connecting member. are doing. This type of ship tends to increase the restoring force against roll and easily form a wide deck.

[0003]

SUMMARY OF THE INVENTION The present invention utilizes the above-mentioned advantages of a double-hulled ship, and provides an underwater observation boat capable of safely boarding a relatively large number of passengers and providing an effective underwater observation. The purpose is to:

[0004]

In order to achieve the above object, according to the present invention, three to five observation drainage bodies provided with an underwater observation room are arranged at a predetermined distance from each other.
A relatively small-volume floating cavity is provided outside each of these drainage bodies, and the whole is integrally connected via a connecting member so as to have a symmetrical shape. The window is formed below the surface of the water at a certain depth, and the floating cavity is formed in a position not to obstruct the view from the observation window.

The three to five observation drainage bodies and the two floating airframes are excellent in measures against rolling (the interior observation drainage bodies are hardly affected) and in restoring force measures, and are generally wide. This makes it possible to form a deck, so that a large number of tourists can safely board and enjoy free-sightseeing. Also, when the floating airframe is flooded by the observation drainage fuselage, it compensates for buoyancy to prevent excessive hull tilting and sinking, and when an obstacle approaches from the side of the hull, it collides with the obstacle and Restricts objects from hitting the viewing window and prevents damage to the viewing window.

[0006] Each observation drainage fuselage is provided with an observation window on each of the opposing side surfaces. Through these observation windows, the passengers in each observation drainage body can intervene underwater. You will be able to see the passengers inside the observation drainage body on the side.

In the present invention, when the propulsion means is provided in each of the observation drainage bodies, the turning displacement of the hull can be quickly performed with a small radius.

In FIG. 1, reference numerals 1A, 1B and 1C denote a pair of left and right observation drainage bodies having an underwater observation room, and 2A and 2B denote relatively small volumes provided outside the drainage bodies 1A and 1C. Floating airframe. These five torso 1A, 1
B, 1C and 2A, 2B are integrally formed by connecting their front and rear portions with a box-shaped connecting member 3.

In this case, the floating cavities 2A and 2B can be made a size of a fraction of that of the observation drainage bodies 1A, 1B and 1C. It is good to generate a large buoyancy.

The underwater observation rooms 4A, 4B, 4C are formed in the submerged portions of the corresponding observation drainage bodies 1A, 1B, 1C, respectively. Observation windows 5 are arranged in a row to view the underwater.
At this time, the observation window 5 on the outer side of the observation drainage bodies 1A and 1C.
Project from the bottom surfaces of the floating cavities 2A and 2B by an appropriate dimension h so that the horizontal view from the observation window 5 is not obstructed by the floating cavities 2A and 2B.

Reference numeral 11 denotes an awning covering the upper part of the promenade deck 8, reference numeral 12 denotes a mast, reference numeral 13 denotes a windlass, and reference numeral 14 denotes a bollard.

An engine room 15 equipped with an engine is provided at the rear of each of the observation drainage bodies 1A, 1B, 1C, and a propulsion device 16 rotated by the engine is provided outside the rear of the engine room 15 outside. It is provided. The propulsion device 16 is turned by rotating the steered wheels in the steering room 9.

An example of use and operation of the underwater observation boat configured as described above will be described. When mooring at the quay, the floating cavities 2A and 2B are berthed. With this, the underwater observation room 4A,
Since the observation windows 5 of 4B and 4C are secured at a certain distance from the quay, damage due to contact with the quay is prevented.

At the time of boarding, the user first gets on the upper deck 6 and moves to the underwater observation rooms 4A, 4B, 4C or the promenade deck 8 via the steps 7, 10.

The navigation is performed by rotating the three propulsion devices 16, and the normal course change is performed by changing the speed and direction of each propulsion device 16. Each propulsion device 16 can also generate a reverse propulsion force, so that turning with a small radius can be performed quickly. At the time of underwater observation, look at the underwater from the observation window 5.

In the present embodiment, the five bodies 1A, 1
The provision of B, 1C, 2A, and 2B is excellent in measures against rolls and restoring force of the hull, and is not affected by the rolls. And the restoring force is great in terms of increasing the ride comfort and safety of the passenger, and the underwater observation window 5 is above the water surface due to the hull inclination. It is excellent in that the situation of being exposed is prevented and the view from the view window 5 is not impaired.

Five bodies 1A, 1B, 1C, 2A, 2B
Are connected by the connecting member 3 and are formed so as to surround the outer periphery thereof, thereby providing a wide boarding place for passengers. The formation of the wide deck and the increase in the above-mentioned restoring force make it possible for many passengers to board.

The five bodies 1A, 1B, 1C, 2A,
The hull consisting of 2B can easily increase the draft of the observation drainage hulls 1A, 1B and 1C as compared with a single hull having the same displacement and the same restoring force. A number of viewing windows 5 can be formed at the location, through which many passengers can simultaneously have a wide range of underwater viewing.

The presence of the floating cavities 2A, 2B is due to the fact that the observation window 5 is damaged and one of the observation drainage bodies 1A, 1B, 1
The horizontal inclination of the hull when inundated in C or the like is kept small, and sinking is prevented even if it is inundated in both the left and right observation drainage bodies 2A and 2B. Moreover, since the floating cavities 2A and 2B act as wave absorbers, even if the waves generated outside the floating cavities 2A and 2B are large, the floating cavities 2A and 2B and the drainage for observation are used. The waves between the bodies 1A and 1C are smaller than the waves generated outside the floating air bodies 2A and 2B, and especially the view environment from the view window 5 outside the view drain bodies 1A and 1C. Is good.

The observation windows 5 provided in the underwater observation rooms 4A, 4B and 4C in the observation drainage bodies 1A, 1B and 1C are as follows.
The underwater observation rooms 4A, 4B, and 4C allow the passengers in the underwater observation rooms 4A, 4B, and 4C to face each other, thereby enabling the passengers in the underwater observation rooms 4A, 4B, and 4C to face each other. The situation of the passenger who is observing the underwater view can be photographed through the underwater, and the enjoyment of the underwater view will increase.

In the above-described embodiment, the floating cavities 2A and 2B have been illustrated and described with the floating cavities 1A and 1C attached slightly outside the observation drainage cylinders 1A and 1C. However, as shown in FIG. Observation drainage cylinders 1A and 1C for 2A and 2B
The observation view from each observation room may not be obstructed, that is, the observation view 5 may be integrated with the observation window 5 at a position above a certain height.

In the above embodiment, three observation drainage cylinders (1A, 1B, 1C) are described.
A configuration in which four are provided may be adopted. That is, FIG.
A, 1B, 1C, and 1D) are side views of an example in which
Is the floating cavities (2A, 2B) at that time attached to the observation drainage cylinders 1A, 1D at a little distance from the outside, and B is the integrated state with the observation drainage cylinders 1A, 1D Shows the one attached to.

Four observation drainage cylinders of the above example (1A, 1
B, 1C, and 1D), the configuration of each part
(1A, 1B, 1C), and the operation and effect are also the same.

Next, five observation drainage cylinders may be provided in the same manner. However, since it becomes too large in the lateral direction and a problem in maneuvering may occur, the number of drainage cylinders is limited to five. It is assumed that.

[0028]

According to the present invention constructed as described above, more passengers can enjoy the underwater view more enjoyably and more than in the case of a monohull, catamaran or trimaran with the same displacement. It can be done safely.

Specifically, the provision of four or five fuselages provides excellent measures against rolling and restoring force, and improves the stability of the hull against waves as a whole and prevents seasickness. In addition, tourists can freely select the observation room at the position they want to see independently, and a wide deck can be secured, and the depth of the draft is increased, so that many observation windows are formed at a deep position below the water surface and in a wide range As a result, it will be possible to respond to the individual tourist desires of a large number of tourists.

Further, since the floating cavities exist outside each of the left and right observation drainage bodies, the influence of waves on the observation windows is reduced, and the observation environment is improved. This makes it difficult for the hull to tilt sideways and prevents sinking.

Furthermore, the passengers in each drainage body can see the passenger's perspective situation in the opposite drainage body through the underwater, and can take a picture of this situation if necessary.

According to the second aspect of the present invention, the hull can be quickly turned with a small radius, and a meaningful underwater view can be performed.
