Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile waterborne report that allows a helicopter to easily take off and land on a water surface in a lake, a river, a calm bay, or the like.

[0002]

2. Description of the Related Art In recent years, helicopters have attracted attention as means for transporting people and various things to destinations at high speed without relying on land-based traffic routes. In particular, because it can reliably transport people and goods regardless of the traffic congestion on land traffic, it has been widely used as an emergency transportation method for transporting sick people and doctors, and for various surveillance activities from the sky. is there. It is also increasingly used as a means of transporting people and goods between factories, research laboratories, and sales offices of each company, and in sightseeing spots, to enjoy a landscape that is different from the landscape on the ground. I have.

When a helicopter is used for such a purpose, a helicopter is required as a helicopter take-off and landing field. However, the helicopter of the helicopter can be located in a relatively small place, so that the rooftop of the building can be used as needed. A schoolyard or the like can be used. However, such a heliport does not always exist in an appropriate place, and when a helicopter must take off and land in the vicinity of the destination in an emergency, it is always a big problem to find that place. Becomes

On the other hand, Japan is surrounded by the sea, and if there is a helipad on the sea, helicopters can be easily used in many places. It is strongly desired that each local government can easily and inexpensively provide a shoreline with a heliport as an emergency or the like. It is also very convenient not only for emergency use but also for sightseeing using a helicopter at coastal tourist spots, and specialized air carriers perform such work at each tourist spot. There is also a need here for easy and inexpensive heliports on the shoreline. Regarding this point, the same is desired not only on the above-mentioned sea, but also on lakes and large rivers.

Conventionally, a floating table using a table that floats on the surface of the water by providing a float has been used as a report on the water.
Anchor fixed to the sea floor, etc.,
There are used ones in which this buoy is fixed to a fixed member on the shore, and one in which a helipad is formed on the ship itself so as to be movable.

[0006]

In the above-mentioned conventional type using a float, it is suitable for a long term use as a heliport in that the float is fixed at a predetermined position on the sea. Transporting or assembling a large platform requires a lot of cost and time, and it is also necessary to work to secure the anchor on the seabed and prevent the floating platform from moving to a predetermined position. Or if it needs to be removed in a short period of time. In addition, the pontoon has no use other than simply as a heliport, and must be removed and stored when not in use, and must be managed.

Therefore, the present invention can be used in shallow seas, lakes, rivers, etc., can be used for various purposes other than as a heliport, and can be manufactured small, lightweight, inexpensively, and has high stability. It is intended to provide a report on movable water.

[0008]

According to the present invention, a flat deck serving as a helipad is provided on a catamaran, and a steering room surrounded by a metal protection pillar is provided at the front of the deck. In addition, a movable waterborne report provided with outboard motors on the left and right of the rear part of the hull.

According to the present invention, since a deck serving as a report is provided on a catamaran as described above, the stability is extremely high as a heliport, and the helicopter does not shake greatly even with a small wave. Less likely to be. Catamaran has a shallow waterline, so when used at sea, helipads can be installed very close to land, and can be used in lakes and rivers even in relatively shallow places. With a wheelhouse at the front of the deck, the helipad can always be located at a predetermined position.When this vessel is shared with the helipad, red tides occur in the sea, including sea rescue, Can be placed in rivers in the city center at the time of early detection, management of aquaculture farms, various works by a work boat for removing algae and aquatic plants, or when a disaster occurs. Also, if you do not share with the ship and helipad,
It can be used as a base for water leisure and mooring for pleasure boats, and can also be used as a floating bridge.

[0010]

Embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1, 2, and 3, a catamaran 3 having a first body 1 and a second body 2 made of fiber-reinforced plastic (FRP) on the left and right sides thereof has both bodies 1, 2 at an upper portion. It has a deck 4 to be connected. The deck 4 is formed on a flat surface, and has a target mark 5 made of a circle, a rectangle, and a fixed area as shown in the figure showing the target at the time of landing of the helicopter H, the mounting position of the helicopter H, and the taxiway. Is attached. This deck 4 can be made of FRP as well as each body. Each of the shells 1 and 2 and the deck 4 can be made of metal. As shown in FIG. 2, four hooks 6 are provided around the target mark 5, and the helicopter H
Is fixed on the ship by hooking it on a predetermined portion of the helicopter H and the hook 6 using a metal fitting (not shown).

A steering room 7 is provided at the front of the deck 4 and is surrounded by a metal protection column 8 such as a roll bar or a prism, so that the helicopter H that arrives and exits the heliport may be misaligned. The rotating blades do not come into contact with the steering room 7 and do not injure the shipfarer. A first outboard motor 10 and a second outboard motor 11 are provided at the rear ends of the first and second barrels 1 and 2, respectively.
Each outboard motor is swingable about a horizontal shaft ship like a normal outboard motor, so that the screw 12 provided at the lower end of the outboard motor exists in the water. An outboard motor elevating device capable of taking a state and a non-use state of being lifted out of the water and located on a boat is provided.
It is desirable that the screw 12 provided at the lower end of the outboard motor be provided above the bottom of the catamaran. Fuel tanks 13 and 14 are provided at the rear of the first barrel 1 and the second barrel 2 and in front of the outboard motors 10 and 11, respectively.

On the side of the deck 4, a handrail 15 for raising and lowering and protection is provided. If necessary, deck 4
A handrail may be provided at a necessary location or on the entire circumference. Also,
Although not shown, a mooring fitting is provided on the ship.

As shown in FIG. 3, a first cylinder 1 and a second cylinder 2
It is preferable that, for example, a piece of wood 17 or a piece of metal 18 is appropriately attached to the bottom portion. Further, the first body 1 and the second body
A metal plate or a synthetic resin plate 17 is provided inside the bottom of the body 2.
It is desirable to stack them appropriately or to make them protrude 18 to be exchangeable at the center of the bottom. Therefore, it is highly likely that this ship is used particularly in shallow waters, and it is considered that the ship sinks greatly when the helicopter H lands, and the hull is damaged when the bottoms of the two bodies come into contact with sand or rocks on the seabed. To prevent that.

In addition, hydraulic cylinders 30 and 31 are installed on the side of the first body 1 and the second body 2, and rods 32 and 33 operated by the hydraulic cylinders 30 and 31 are connected to form rods 32 and 31.
At the end of 33, anchors 34, 35 are provided, and when the report is anchored above the water, the anchors 34, 35 are extended vertically downward, inserted into the sea floor, lake bottom or river bottom, and the hull sways due to the waves May be prevented. Further, a shaft may be penetrated through the lower surface of the deck 4 and a fin may be provided on the shaft in the swing direction.

In the present invention, since the deck serving as a report is provided on the catamaran as described above, the report has a small amount of drainage because the report is excellent in elasticity. Also, when the helicopter takes off and land on the report, a downwash phenomenon occurs.If the helicopter is a small aircraft, it will move at a speed of about 5 knots in the wind direction, and if it is a large aircraft, it will travel at a speed of about 15 knots. It is desirable that the small surface helicopter be movable, even if safe takeoff and landing is not possible without it. Catamaran has a shallow waterline, so when used at sea, helipads can be installed very close to land, and can be used in lakes and rivers even in relatively shallow places.

Further, since a steering room is provided at the front of the deck,
This ship can be made to travel to a predetermined position, and the helipad can be always arranged at a predetermined position against ocean currents and waves during use. Further, when the weather is rough and dangerous during use, the user can move to a safe port or the like with the helicopter mounted and evacuate.

When this ship is not used as a heliport, it can be widely used for various operations such as management of aquaculture farms and a work boat for removing algae and aquatic plants.

Further, since the periphery of the steering room is surrounded by a metal protection column such as a roll bar, the helicopter which arrives and departs at the heliport is displaced by any chance, and the rotating blades come into contact with the steering room, and Does not cause injury. In addition, since the outboard motors are provided on the left and right at the rear of the hull, after the ship has sailed to the predetermined shallow water, the outboard motor is raised from the sea to the ship, and the helicopter lands on the ship in the shallow water. Even if the ship sinks a little when it does, it will not damage the screws etc., and the ship can be moved safely to a shallower water.

Further, since a reinforcing plate such as a metal plate or a resin plate is laminated on the bottom of the hull, the hull can be prevented from being damaged even if the bottom of the hull comes into contact with the sea bottom. Since the helicopter can be moved to a location near the lake shore and a helicopter passenger can be easily and quickly transported between land and a ship, the function as a waterborne report is improved.

[0020]

According to the present invention, since the deck serving as a report is provided on the catamaran as described above, the helicopter does not greatly shake even with a small wave, and has extremely high stability as a heliport. Is less affected by Also, catamaran has a shallow draft, so when it is used in the sea, a helipad can be installed very close to the land, and a helipad can be installed relatively shallow in lakes and rivers. It can be used in relatively shallow places such as lakes and rivers. In addition, since the wheelhouse is provided at the front of the deck, the ship can be driven to a predetermined position by itself, and the helipad can always be arranged at a predetermined position against sea currents and waves during use. . Further, when the weather is rough and dangerous during use, the user can move to a safe port or the like with the helicopter mounted and evacuate. When not using this ship as a heliport,
It can be widely used for various operations such as management of aquaculture farms and work boats for removing algae and aquatic plants.

Further, since a reinforcing plate such as a metal plate or a resin plate is laminated on the bottom of the hull, even if the bottom of the hull comes into contact with the sea bottom, the hull can be prevented from being damaged. Since the helicopter can be moved to a location near the lake shore and a helicopter passenger can be easily and quickly transported between land and a ship, the function as a waterborne report is improved.
