Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a water helicopter, and is installed on the water to support a transportation system such as a helicopter, particularly in an area where land helicopter facilities are lacking. It relates to a semi-submerged water heliport.

[Conventional technology]

Conventionally, as a water heliport, for example, those shown in FIGS. 3 to 6 are known.

That is, the water heliport 1 shown in FIG. 3 and FIG.
A float 4 is attached to a lower portion of the helipad body 2 via a column 3 extending into the water.

The water heliport 1 is floated on the water by the buoyancy of the float 4, and as shown in FIG. 3, the heliport main body 2 is fixed to an anchor 5 buried in the sea floor with a chain or the like 6 and installed on a predetermined water. ing.

The water helicopter 10 shown in FIG.
12 is formed as a heliport.

In addition, the water heliport 20 shown in FIG.
21 is a heliport, which is docked on the quay 22.

[Problems to be solved by the invention]

However, since any of the water heliports 1, 10, and 20 shown in FIGS. 3 to 6 are themselves floating on the water surface by buoyancy, the water heliports 1, 10, and 20 themselves are caused by waves or the like. Will shake.

No measures have been taken to control this shaking in any of the water heliports 1, 10, and 20, so it was not easy for a helicopter to take off and land on the water heliports 1, 10, and 20.

In addition, when these water heliports 1, 10, and 20 are permanently installed, the water traffic of ships and the like may be hindered.

Therefore, the water heliport 1 shown in FIGS.
, The water heliport 1 is connected to the ship 7
The tow helicopter 1 is towed and moved to a place where it does not hinder water traffic. However, since the heliport main body 2 is fixed to an anchor 5 buried in the water bottom with a chain 6 or the like, the anchor 5 There is a problem that it is necessary to remove the chain 6 and the like.

In the water heliport 10 shown in FIG. 5,
Since the deck 12 of the ship 11 is formed as a helipad, its movement is easy, but there is a problem that the ship 11 becomes relatively large.

Further, in the case of the water heliport 20 shown in FIG. 6, since the floating pier 21 berthed to the quay 22 is used as the helipad, it occupies a relatively wide area of the water surface when not in use. There is a problem that it becomes an obstacle to berthing of ships.

In view of the above points, the purpose of the present invention is to prevent the sway caused by the waves and facilitate the takeoff and landing of the helicopter,
Another object of the present invention is to provide a water heliport that does not hinder the navigation of other ships.

[Means for solving the problem]

According to the water helicopter of the present invention, the above-mentioned object has an upper float in which a helipad body is a flat hollow body having a helicopter take-off and landing deck formed on an upper surface thereof, and is arranged in parallel with the upper float at a predetermined interval. The lower float, which is located and is a flat hollow body that is constantly submerged in water, and a support column interposed between the floats and communicating the hollow chamber between the upper float and the lower float. ,
The heliport body is provided with a weight connected to the heliport body so as to be freely extended therefrom, and when the weight is applied to the heliport body and the weight of the weight acts on the heliport body, the water surface becomes the upper float position, and the weight connected to the heliport body is provided. The weight and volume of the heliport body and the weight are set in relation to buoyancy so that the water surface is at the position of the support column when the weight of the weight does not act on the bottom of the water.

In the above configuration, preferably, a chain winding device is provided in the cylindrical support column, and a plurality of windable weights with chains can be uniformly arranged on the heliport body.

[Action]

According to the above configuration, when the helicopter is to take off and land on the takeoff and landing deck formed on the upper surface of the upper float, the weight connected to the heliport body is extended and seated on the water bottom. Then, since the weight of the weight does not act on the heliport main body, the heliport main body rises, and the water surface is located at the position of the support column of the heliport main body.

Therefore, since it is the portion of the support column of the heliport body that is located on the water surface where waves are generated, since the contact area with the wave is small, the helicopter body is hardly affected and the swing of the heliport body is prevented, and the helicopter takes off and landing. Can be easier.

On the other hand, when moving the heliport main body, the weight is seated on the heliport main body, and the weight of the weight acts on the heliport main body. Then, the heliport body sinks and the water surface is at the position of the upper float of the heliport body.

Accordingly, the upper float portion of the heliport body floats on the water surface, and the heliport body is provided with a drive device to be self-propelled, or towed by a ship and towed by another ship for navigation. It can be easily moved to an unobstructed place.

In addition, when a plurality of chain-wound free weights are uniformly arranged on the heliport body, the swing of the heliport body is made uniform in addition to the above-described operation.

〔Example〕

Hereinafter, a preferred embodiment of the water heliport of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1A and 1B, the water heliport 30 according to the present invention mainly comprises a heliport body 31 and a weight 32 connected to the heliport body 31 so as to be freely extended therefrom. I have.

The heliport main body 31 has an upper float 34 on which a helicopter takeoff / landing deck 33 is formed on the upper surface, a lower float 35 positioned parallel to the upper float 34 at a predetermined distance from the upper float 34, and Support pillar 3 interposed
It is composed of six.

The upper float 34 and the lower float 35 are formed in a rectangular flat plate-like hollow body of the same size using steel material or fiber reinforced plastics (hereinafter referred to as FRP) or the like. These materials are appropriately selected in consideration of the size, overall weight, manufacturing cost, and the like of the heliport body 31.

The support pillars 36 are provided between the four corners of the lower float 35 to support the four corners of the upper float 34 by being erected between the four floats, and the hollows of the upper float 34 and the lower float 35 are provided. It is formed by a communicating rectangular cylinder.

These support columns 36 are formed using a steel material, FRP, or the like, like the upper float 34 and the lower float 35 described above.

Further, the weight 32 is formed of a weight with a chain that can be freely wound, and a plurality of the weights 32 are evenly arranged on the heliport body 31. Specifically, as shown in FIGS. 2 (A) and 2 (B), the weight 32 with a chain is suspended from the inside of each of the support columns 36, and a chain winding is provided in each of the support columns 36. A device 37 is provided for each.
That is, the chains 38 of the weight 32 extend through the bottom surfaces of the four corners of the lower float 35.

It is also conceivable to employ a wire or the like instead of the chain 38.

The chain winding device 37 includes a motor 40, a speed reducer 41, and a reel 4 fixed to a mounting table 39 provided on the inner wall of the support column 36.
It consists of two.

The weight and volume of the heliport main body 31 and the weight 32 are, in relation to buoyancy, when the weight of the weight 32 acts on the heliport main body 31, the water surface WL becomes the position of the upper float 34,
When the weight of the weight 32 does not act on the heliport main body 31, the water surface WL is set to be substantially at the center of the support column.

 Next, the operation of the above embodiment will be described.

According to the waterborne heliport 30 of the present embodiment, when the helicopter is to take off and land on the takeoff and landing deck 33 formed on the upper surface of the upper float 34, the helicopter is provided in each of the four support columns 36 of the heliport body 31. Motor of chain winding device 37
By driving the 40 and rotating the reel 42 via the speed reducer 41, the chain 38 connected to the reel 42 is extended, and the weight 32 attached to the tip of the chain 38 is seated on the water bottom WB. Specifically, in a state where four weights 32 are seated on the water bottom WB, the chains 38 connected to the weights 32 are strongly pulled into the support pillars.
The chain winding device 37 is operated until it is brought to approximately the center of 36.

When the weight 32 is seated on the water bottom WB, the weight of the weight 32 is applied to the water bottom WB, so that the weight does not act on the helipad body 31.

Therefore, the heliport main body 31 rises more than usual, and the water surface WL is located substantially at the center of the support column 36 of the heliport main body 31.

As described above, since the portion of the support pillar 36 of the heliport body 31 is located on the water surface WL where the wave is generated, the contact area with the wave is small, so that it is difficult to be affected by the wave and the swing of the heliport body 31 is prevented. And make it easier for helicopters to take off and land.

In addition, support columns located at the four corners of the heliport body 31
Since the weights 32 with chains are provided on the respective 36 and are evenly positioned, and the chains 38 connected to the weights 32 are adjusted to be slightly stretched, so that the heliport body 31 is prevented from swinging. At the same time, it is made uniform.

On the other hand, when moving the heliport body 31,
By driving the motor 40 of the chain winding device 37 and inverting the reel 42 via the speed reducer 41, the chain 38 connected to the reel 42 is wound, and a weight attached to the tip thereof.
32 is positioned below the heliport body 31. When the weight separates from the water bottom, the weight of the weight 32 acts on the heliport body 31.

Then, the heliport body 31 sinks and the water surface WL is at the position of the upper float 34 of the heliport body 31.

Therefore, the portion of the upper float 34 of the heliport main body 31 floats on the water surface WL, and the heliport main body 31
The vehicle can be easily moved to a place where it does not hinder the navigation of another ship if it is self-propelled with a driving device or towed by a ship.
