Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a semi-submerged catamaran, and more particularly to a semi-submerged catamaran suitable for taking off, landing and storing a helicopter.

1 and 2 show a conventional ship equipped with a helicopter and engaged in patrol, rescue, investigation, etc., with FIG. 1 being a side view and FIG. 2 being a top view.

In Figure 1.2, 01 is the hull, 02 is the superstructure, 03 is the cockpit, 04a and 04b are the propellers, and 05g.

05b is the rudder, 06a and 06b are the propulsion shafts, 07a and 07b
is the bracket, 08 is the helicopter deck, 09 is the helicopter hangar, 010 is the waterline, 011 is the helicopter
1012 indicates a chimney, and 013 indicates a mast.

As shown in Figures 1 and 2, ships equipped with helicopters engaged in patrol, rescue, and investigation are usually equipped with helicopter decks at the rear of the ship. 3, a helicopter hangar 09 is provided in front of it, and if necessary, the helicopter 011 can be pulled out from the hangar 09 to the helicopter deck 08, taken off from the helicopter deck 08, carried out the required work, and then re-entered. It will arrive on helicopter deck 08 and be stored in hangar 09.

Additionally, this ship has a chimney o12 in front of hangar 09. Mast 013. Superstructure 02. Conventional ships are equipped with various facilities such as a cockpit 03 and a helicopter deck 08. Hangar 0
9. Since the cockpit 03 and the like are arranged in the longitudinal direction, the hull 01 inevitably makes a large noise, and there is a problem α in that construction of this type of ship requires a large amount of cost.

In addition, conventional ships have a large sway in waves, especially rolling, which makes it difficult for Helicopter 011 to take off and land in the waves, and in rough weather with strong waves, the ship's purpose of patrolling, rescue, investigation, etc. There is a problem that it becomes impossible to perform the work.

The ship shown in Figures 1 and 2 has propellers 04a, 04b, rudders 05a, 05b, and a propulsion shaft 06a on the port and starboard sides of the stern.
.

Although this is a two-shaft, two-rudder boat equipped with 06b, there are also two-glaze, one-rudder boats and one-shaft, one-rudder boats that are used for the same purpose as conventional technology.

The present invention aims to solve these problems, and is a semi-submersible twin-hulled helicopter capable of taking off, landing and storing a helicopter, and used for patrol, rescue, investigation, etc. The purpose is to provide ships.

Therefore, the semi-submerged catamaran of the present invention has a pair of left and right submerged bodies located below the water surface, an upper hull located above the water surface, and a pair of left and right submerged bodies that penetrate through the water surface. In a semi-submerged catamaran equipped with one or more pairs of supports each connected to the water body, a deck consisting of one plane is formed at the top of the upper hull, and a platform for raising and lowering the elevator is located at the center of the deck. It is characterized by being fitted into an opening provided in the section so as to form the same surface as the deck.

A cover is provided to cover the opening created in the deck by lowering the base plate, and a hangar is formed below this cover.

Hereinafter, a semi-submerged catamaran as an embodiment of the present invention will be explained with reference to the drawings. Figures 3 to 6 show the first embodiment,
Figures 7 and 8 show the second embodiment, Figures 3 and 7 are side views, Figure 4 is a top view, Figure 5 is a sectional view taken along line V-V in Figure 3, and Figure 6 The figure is a sectional view showing the state in which the helicopter is retracted from the state shown in Fig. 5, and Fig. 8 is a cross-sectional view of the state shown in Fig. 7.
3 to 8, reference numeral 1 is the upper hull, 1' is the lower surface of the upper hull, 1θ is the plate support for one elevator, 2a and 2b are the submerged bodies, and 3a.

3b, 3a', 3b' are pillars, 4 is superstructure, 5a,
5b is a propeller, 6a, 6b are rudders, 7a, 7b are front hydrofoils, 8a, 8b are rear hydrofoils, 9 is a waterline, 1o is a cockpit, 11 is a helicopter deck, 12 is an elevator plate, 13 is a Reference numeral 114 indicates a cover for the helicopter, and 15 indicates a helicopter storage space as a hangar. The suffix a in each symbol indicates the port side, and b indicates the starboard side.

First of all, to explain the first embodiment shown in Figs.
This relates to a semi-submerged catamaran in which the two are connected by one strut 3 at 3 b, respectively.

As shown in FIGS. 3 to 5, an upper structure 4 and a cockpit 10 are provided above the upper hull 1, and a helicopter deck 11 consisting of one plane is formed at the top.

An opening is provided in the center of the helicopter deck 11, and when the single elevator plate 12 is raised, the single elevator plate 12 fits into the opening and forms the same surface as the helicopter deck 11. Then, the helicopter 13 can take off or land on the ship.

Further, as shown in FIG. 6, when the one-elevator plate 12 is lowered by a lifting device (not shown) and the one-elevator plate holder on the upper surface of the upper hull 1 reaches a portion 1'', the helicopter 13 moves the surrounding area to the upper part. The helicopter is housed in a helicopter storage space 15 as a hangar surrounded by the structure 4. This helicopter storage space 15 covers the opening of the helicopter deck 11 with a cover 14 made of cloth or plate material as required. This makes it possible to isolate it from the outside world.

As mentioned above, by forming the helicopter deck 11 in one plane on the top of the upper hull 1 of the semi-submerged catamaran,
This semi-submersible catamaran is much smaller in size than conventional ships, and can secure a sufficiently large area for the helicopter deck 11, as well as avoid any obstacles around it (hangar 09, chimney 012, etc. in Figure 1). Since there is no mass) 013 etc.),
The helicopter 13 can easily take off and land on the ship.

In addition, semi-submerged catamarans have less hull sway (especially while sailing).
Therefore, even in rough weather, the helicopter 13 can easily take off and land on the ship, and the purpose of use of the ship, such as patrol, rescue, and investigation, can be fulfilled.

On the other hand, a semi-submerged catamaran can secure a large deck area compared to the size of the ship, so the helicopter storage space created by lowering the elevator plate 12 installed in the center of the helicopter deck 11 Helicopter on 15-13
It is possible to store the helicopter 13 when it is not in use, and to perform maintenance and repairs as necessary.

7 and 8 show a second embodiment of the present invention, in which a pair of left and right submerged bodies 2a, 2b and one upper hull 1 are supported by two supports 3a, 3b, 3, respectively. a',
This relates to one semi-submerged catamaran connected at 3 b'.

In this second embodiment, similarly to the first embodiment described above, a single plane helicopter deck 11 is formed at the top, and an elevator plate 12 is provided in an opening in the center of the helicopter deck 11. Since they are provided so that they can be fitted together to form the same surface as the helicopter deck 11, the same effects as in the first embodiment can be obtained.

As detailed above, according to the present invention, in a semi-submerged catamaran in which a pair of left and right submerged bodies located below the water surface and an upper hull above the water surface are connected by a support, the top A simple structure in which the platform for raising and lowering the elevator fits into an opening provided in the deck to form the same surface as the deck allows the lifter to take off, land, and store ships. As a result, vessels used for patrol, rescue, investigation, etc. can be configured with much smaller dimensions than before, resulting in significant savings in construction. On the other hand, semi-submerged catamarans have less hull sway, so they can withstand rough weather. Another advantage is that helicopters can easily take off and land inside the ship.
