Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention is a helicopter floating base for setting a helicopter landing base on a desired lake or sea. More specifically, this is a helicopter floating base that can quickly and easily form a helicopter floating base by carrying it by helicopter to the sea surface to be set and gradually lowering it on the water surface.

[0002]

[Prior art]

 It is clear that helicopters that do not require large landings will be used more and more in the future. However, since landing sites cannot be easily set on water or at sea, construction of water landing sites for helicopters is required.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to solve the above-mentioned conventional problems, and the purpose of the present invention is to simply set up a helicopter landing site for a helicopter simply by transporting and landing on a lake, sea, etc. by a helicopter. To provide a water base.

[0004]

[Means for Solving the Problems]

 In the present invention, a plate-shaped synthetic resin foam (1) and a rectangular parallelepiped FRP box (2) provided with a water storage cavity (3) are placed on top of the synthetic resin foam (1). A helicopter floating base (A) in which the FRP box (2) is vertically joined together so that the FRP box (2) is at the bottom, and the FRP box (2) has holes (7) in the bottom plate (5). ) Has a plurality of holes (7) for water inflow having a check valve (8), and a side plate (4) is provided with a deaeration hole (6) and a drain valve (12). It is a floating base for helicopters that can be carried by sea. When the floating base body of the present invention is transported by a helicopter and gradually lands on the water surface to be set, the check valve (8) provided on the bottom plate (5) of the FRP box body (2) provided at the lower part is used. Water flows in through the water inflow hole (7), and the water filled in the cavity (3) acts as a weight, forming a safe landing base for helicopters without capsizing.

[0005]

[Embodiment of the invention]

 An example of the method for manufacturing a floating base according to the present invention will be described with reference to FIG. A rectangular parallelepiped box (2) having a plate-shaped synthetic resin foam (1) made of a foamed resin such as styrofoam, and having a water storage cavity (3) inside made of a robust resin material such as FRP. make. The bottom plate (5) of the box (2) is provided with a plurality of holes (7) for water inflow, and these holes are provided with check valves. The side plate (4) of the box (2) is provided with a deaeration hole (6) and a drain valve (12) at an appropriate place. The number of the deaeration holes (6) may be one, but a plurality is preferable. At least one drain valve (12) is provided below the side plate (4) near the bottom plate (5). The drain valve (12) is used in a closed state. Although the upper plate of the box (2) is not provided in FIG. 2, an upper plate may be provided as shown in FIG. Next, the synthetic resin foam (1) and the FRP box (2) shown in FIG. 2 are joined so as to be vertically integrated with an adhesive or the like, and the floating base for helicopter of the present invention is manufactured. The hollow portion (3) of the box (2) may be a single large room, or may be divided into a plurality of hollow portions by a perforated partition (14). The number of cavities is not particularly limited. Considering the strength of the box (2) and the balance at the time of storing water, the partition (14) is used as appropriate. In FIG. 2, the cavity (3) is divided into six cavities. Each cavity is connected by a hole in the partition (14).

When the floating base of the present invention is floated on the water, as shown in FIG. 1, water (9) is discharged from a hole (7) with a check valve (8) provided on the bottom plate of the box (2). The air flows rapidly, and the air in each of the cavities (3) and (3) finally escapes from the deaeration hole (6) through the perforated partition wall, and the cavities (3) and (3) are filled with water. . The floating base (A) becomes a safe floating base for helicopters even when the helicopter (10) rides on it and balances with the plate-shaped synthetic resin foam (1). The plate-like foam (1) may be a foam made of a polystyrene-based copolymer or a mixed resin, in addition to a foamed polystyrene foam alone. Since the plate-like foam (1) is a closed cell, it is excellent in moisture resistance, weather resistance and corrosion resistance, lightweight, easy to mold, and inexpensive. The size of the plate-like body (1) and the FRP box (2) using polystyrene foam (specific gravity 0.02 to 0.03), the volume of the cavity (3), etc. can be freely adjusted according to the desired weight and strength. Can be used in combination. The plate-shaped synthetic resin foam (1) can be used in the range of 50 cm to 200 cm in thickness and 200 cm to 500 cm in each of vertical and horizontal directions. As an example, a plate-like foam (1) (thickness 50 cm, vertical x horizontal 500 x 500 cm) and an FRP box (depth 30 cm, vertical x horizontal 500 x 500 cm) can be mentioned. The floating base (A) of the present invention can be used by connecting a plurality of floating bases (A) to each other by the connecting means (11) as shown in FIG. As the connecting means (11), known means such as a bolt and a rope can be used. In order to facilitate helicopter landing, a veneer plywood, a punched aluminum plate or the like may be placed on the upper surface of the plate-like foam (1) for use. Furthermore, when the floating base body of the present invention is used and lifted up by a helicopter with the drain valve (12) opened, the water stored in the cavity (3) can be easily drained, and can be easily drained. Can be moved and collected.

[0007]

[Effect of the invention]

 The helicopter floating base of the present invention is lightweight and easy to handle in an emergency. Furthermore, it is easy to manufacture and inexpensive. When floating on the water, water quickly flows into the cavity (3) of the FRP box, and the stored water acts as a weight, and a safe floating base that does not overturn due to waves or the like is desired. Can be set freely in place.
