Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a float device that can effectively prevent pitching (pitching) due to high waves in a marine house or the like installed on the sea.

2. Description of the Related Art A structure such as a marine house as a leisure facility may be installed at sea.

Such a structure may be fixed via a support structure standing on the sea floor, but a mooring line is provided between the building and an anchor block installed on the sea floor, and the structure is moored at a fixed position while floating on the sea surface. There are many things.

Problems to be Solved by the Invention According to the former of the prior art, the support structure standing on the sea floor is unavoidably exaggerated, and the installation cost tends to be excessive. Is limited. In the latter case, there is an unavoidable problem that the structures floating on the sea surface are affected by the waves, and excessive pitching occurs particularly in high waves, so that the habitability is significantly impaired.

Therefore, an object of the present invention is to provide a float device that can effectively prevent pitching of a structure that floats on the sea surface and is moored by combining a cylinder and a piston in view of the problems of the related art. It is in.

Means for Solving the Problems The configuration of the present invention for achieving this object includes a cylinder that is installed upward on an underwater float, a piston that is slidably housed in the cylinder, and that supports a structure on the water, And a high wave float mounted on the piston on the upper side.
The structure is levitated through the piston, the cylinder draws seawater into the lower working chamber through the one-way valve by raising the piston, and a small cross-sectional area formed in the one-way valve is formed by the lowering of the piston. The gist of the present invention is to discharge seawater in the working chamber to the outside via the working chamber.

The cylinder has a stopper that defines the lower limit of the piston.
A lid may be provided to define the upper limit of the piston.

Further, the high wave float may be formed in a disk shape in which a piston penetrates a center portion vertically.

According to the structure of the invention, the high wave float is
During high waves, lift the structure through the piston,
The cylinder sucks seawater into a lower working chamber through a one-way valve by raising the piston. When the high waves leave, the piston descends, but at this time, the cylinder discharges a small amount of seawater to the outside through the small cross-sectional area formed in the one-way valve, so that the cylinder until the next high wave arrives It is possible to reduce the amount of lowering of the structure that occurs therebetween, and effectively prevent harmful pitching. In addition, a cylinder shall be installed upward in a float underwater, and shall be fixed to a fixed position in water via a mooring line.

If the cylinder is provided with a stopper and a lid,

The float unit 30 is composed of float devices 31, 31,... And underwater floats 32, 32, ... arranged at the four lower corners of the deck unit 20, and floats the deck unit 20 on the sea surface F. Note that reinforcing beam members 31a, 31a,...

The artificial reef 40 is, for example, a hollow tetrahedral block.
It is formed by stacking 41, 41 ... on the sea floor. In addition, the artificial reef 40 may use a block of any other shape.

The mooring line 50 moores the float portion 30 to the artificial reef 40. The mooring line 50 includes first ropes 51, 51 ... connecting the floats 32, 32 ... to the reinforcement floats 61, second ropes 52 connecting the auxiliary floats 61 to the artificial reef 40, and each float 32 to the seabed anchor block 53a.

The float devices 31, 31,... Of the float portion 30 each include a cylinder 32a and a piston 32a (FIG. 3).

The cylinder 32a is installed upward on the upper surface of the underwater float 32, and the piston 31a is slidably housed in the cylinder 32a via a lower end piston ring 31b. Note that the piston 31a supports the floor 21 of the deck section 20. A stopper 32al that defines the lower limit of the piston 31a is formed in the cylinder 32a, and a lid member 32b that defines the upper limit of the piston 31a is fixed to the upper end.

An opening 32d is provided in a lower portion of the cylinder 32a, and a one-way valve 32c is mounted in the opening 32d. However, the one-way valve 32c is formed with an outflow hole 32cl having a small cross-sectional area.

A disc-shaped float for high waves 31c is mounted on the piston 31a via fixing members 31d, 31d. However, the piston 31a vertically passes through the center of the high-wave float 31c. The float for high waves 31c
It generates buoyancy greater than 2 and is fixed above sea level F in the steady state.

When the sea is calm and there are no waves, the piston 31a descends to the lower limit defined by the stopper 32al and is supported by the stopper 32al. The working chamber 32e of the cylinder 32a below the stopper 32al is filled with seawater.

Then, when the high waves come and the sea surface F rises and becomes higher than the lower surface of the high wave float 31c, buoyancy is generated in the high wave float 31c, and the high wave float 31c moves the deck portion 20 and the building 10 through the piston 31a. To surface. Meanwhile, float
The cylinder 32a on 32 is fixed in the water because the float 32 is moored by the first rope 51 and the third rope 53. Therefore, the piston 31a at this time rises in the cylinder 32a, and the cylinder 32a sucks seawater into the lower working chamber 32e via the one-way valve 32c.

Next, when the sea surface F suddenly lowers in the valley of high waves, the piston 31a descends, and the cylinder 32a
The seawater in the working chamber 32e is discharged to the outside via the. However, since the seawater in the working chamber 32e can be discharged only little by little through the outflow hole 32cl, the piston 31a only descends slowly. In other words, the piston 31a follows the swell of the high waves and rises quickly to push up the deck portion 20, and then gradually descends, so that the deck portion 20, the building
10 pitching can be effectively prevented.

In the above description, the power generation facility 13 may be a wave power generation type or a wind power generation type.
