Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a float mounted on a pollution control membrane, an oil fence, or the like.

[0002]

2. Description of the Related Art Conventionally, floats mounted on a pollution control membrane or the like include spherical floats, cylindrical floats, and the like. These floats always float on the water surface because the air is sealed inside. However, for example, when it is attached to the sea or the like, when the sea is rough, the wave sometimes damages the float. In recent years, there has been proposed a float that can sink to the bottom of the sea when the sea is shrunk.

[0003] As these float-float type floats, there is a type in which a tube-like float is usually filled with air, and when settled, air is removed. However, if such a float is evacuated to some extent, it will bend under the influence of ocean currents etc. at the anchor mooring part, and it will not be able to settle to the desired seabed because the air will not escape enough. was there.

[0004]

The inventor of the present invention has conducted various studies on these conventional floating-sink type tubular floats having no drawbacks, and as a result, completed the present invention.

[0005]

That is, the present invention relates to a float which can be floated and lowered by providing a small inner bag inside the outer bag and filling the bag with water and / or air.

Next, a description will be given with reference to the drawings. FIG. 1 is a longitudinal sectional view showing the float of the present invention in a slightly expanded state. First, the present invention will be described by taking as an example a case where a float is formed using an inflatable material such as a rubber sheet.

In FIG. 1, a rubber sheet 1 and a rubber sheet 2
Are bonded to the upper edge 3 and the lower edge 4, respectively, to form an airtight state. In this way, the rubber sheet 1 and the rubber sheet 2 are separated from each other in the intermediate portion. A rubber sheet 7 and a rubber sheet 8 are provided to provide the outer bag 6 outside the inner bag 5 thus configured.
The inner bag is integrally adhered to the upper and lower ends.
It is necessary to as a method of bonding the rubber sheet and the rubber sheet 1 and the adhesive length l ₂ smaller than the adhesive length l ₁ of 2 constituting the inner bag body as shown in FIG. 1 in this case upper portion .

If air or water is filled into the floating float tube thus constructed, the bag A and the bag B
Is configured.

By providing a through hole 9 in the bonding portion of the inner bag, air or water can be filled from one location of the outer bag B to supply the whole inside of the outer bag. The inner bag 5 and the outer bag 6 are provided with air supply / exhaust ports 10 and 11, respectively. This air supply / exhaust port 1
The inner bag 5 and the outer bag 6 are filled with air or water through 0,11.

By providing water supply / drainage ports 12 and 13 at the bottom of the outer bag 6 and the inner bag 5, air supply / exhaust or water supply / drainage in the bag can be performed in a short time.

The length of the floatation type float according to the present invention is adjusted to an appropriate length depending on the location or purpose of attachment. Next, the method of using the floating float of the present invention will be described. First, when it is desired to give the float / float float the maximum buoyancy, it is achieved by feeding air through the air supply / exhaust ports 10 and 11 to fill the inner bag 5 and the outer bag 6. Conversely, if both bags are filled with water, for example, the suspended pollution control membrane will settle under its own weight and sink to the bottom of the water. it can.

Further, by filling water and air into separate bags, it is possible to keep the bag floating in water. For example, when the float is to be immersed under the water surface, the air in the outer bag 6 may be released after filling the inner bag 5 with water. In this case, since the inner bag 5 is filled with water, tension is applied to the float. Since the state can be maintained, the air inside the outer bag body 6 can be smoothly discharged because the "-" shape does not bend due to the tide or the like.

[0013]

According to the present invention, the float of the present invention can be floated vertically in any state by adjusting the amount of the remaining air, and the air inside the bag can be easily removed.
