Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a floating buoy, and more particularly to a floating buoy that is installed at least at a corner of a floating fence that is extended.

b. Prior Art Floating fences are widely used in the sea, lakes, etc. as oil fences or fences for preventing the diffusion of contaminated water.

Here, FIG. 5 shows an example of this, in which a floating polluted water diffusion barrier fence is installed on the coast to prevent the dispersion of sediment or mud generated at the reclamation construction site 101. 10
It is 2. The fence 102 has a structure in which it floats on the water surface at all times with floaters 103 installed at appropriate intervals.In order to maintain the fence 102 in a stable state at a predetermined position, anchors 104 are installed on the seabed. Anchor chain 10
It is fixed by 5.

However, such a floating fence 102
When the floater is used for a long period of time, drifting materials such as wood may accumulate in the corner portion A, and the drifting materials may damage the floater 103 of the float, shortening its lifespan.

The present invention has been made in view of the above-mentioned problems associated with the extended floating fence, and its purpose is to drag a part of the floating fence into the sea and release part of the damming action, thereby removing floating debris. The purpose of the present invention is to provide a robust floating buoy capable of passing through at least one corner of a floating fence to be extended. The floating buoy is a floating type buoy installed in a section, and the floating type buoy has a robust constant buoyancy chamber in the upper part and a robust variable buoyancy chamber in the lower part which is larger than the constant buoyancy chamber. A pipe for supplying and exhausting gas such as air in the variable buoyancy chamber is connected to the upper surface of the variable buoyancy chamber by penetrating the constant buoyancy chamber connected above. A pipe for flowing in and out of liquid such as seawater is connected to the buoy, and a connecting portion for the floating fence is provided on the side surface of the floating buoy.

d Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a plan view showing a floating fence according to the present invention installed on the coast of a reclamation construction site. Figure Note 1 is a floating type polluted water diffusion prevention fence, and the fence 1 is always maintained floating on the water surface due to the presence of floaters 2 installed at appropriate intervals. 3 is fence 1
This is an anchor chain that connects the fence 1 of the anchor 4 sunk to the seabed in order to stably extend it to a predetermined position on the coast. Reference numeral 5 denotes a floating buoy installed at the corner of the expanded fence 1, and as shown in FIGS. It has a robust constant buoyancy chamber,
A variable buoyancy chamber 7, which is larger than the constant buoyancy chamber 6 and is also robust, is connected below the constant buoyancy chamber 6. On the upper surface of the variable buoyancy chamber 7, a supply/exhaust pipe 8 for supplying and exhausting the air in the variable buoyancy chamber 7 is provided to protrude through the constant buoyancy chamber 6, as shown in FIG. A seawater inflow/outflow pipe 9 is protrudingly provided for introducing or discharging seawater into the variable buoyancy chamber 7. The supply/exhaust pipe 8 is connected to an air supply valve 11 and an exhaust valve 12 via a hose 10, and a hose 13 having an open end is connected to the seawater inflow/outflow pipe 9. In addition, the floating buoy 5
On the side wall of, there is a joint part 1 with the above-mentioned floating fence 1.
4 is installed, and the joint 14 has a hollow tubular shape, and the pin 15 provided on the short part of the floating fence 1 is inserted into the hollow tubular joint 14 to connect. Reference numeral 16 designates an anchor chain that connects the floating buoy 5 with an anchor 17 sunk on the seabed in order to maintain the floating buoy 5 in a predetermined position in a stable state.

As mentioned above, the floating type buoy 5 according to the present invention has the following features:
It is installed at least at the corner of the floating fence 1 extended on the coast, etc., where floating debris tends to accumulate, and is used to release a part of the damming action of the floating fence 1 so that the floating debris can pass through. do.

In this operation, the exhaust valve 12 connected to the variable buoyancy chamber 7 is opened, and the air inside the variable buoyancy chamber 7 is discharged into the atmosphere through the pipe 8, the hose 10, and the exhaust bubble 12. At the same time, seawater flows into the variable buoyancy chamber 7 from the seawater inflow and outflow pipe 9 connected to the lower surface, and the floating buoy 5 gradually loses its buoyancy and begins to sink. In this case, since the floating buoy 5 has a constant buoyancy chamber 6 installed above it, the buoy 5 sinks in a stable state while maintaining its vertical state, and the air inside the variable buoyancy chamber 7 Even when the buoy is completely replaced with seawater, a certain buoyancy acts on the floating buoy 5, allowing it to stop at a predetermined position in the sea as shown in FIG. Therefore, damage to the floating buoy 5 or floating fence 1 due to collision with the seabed can be prevented, and the lower end of the seawater inflow and outflow pipe protruding from the bottom of the floating buoy 5 is buried in the seabed. It is never stored away and is always kept open.

Conversely, when floating the floating buoy 5,
The air supply valve 11 communicating with the variable buoyancy chamber 7 is operated to introduce air from a compressed air supply source (not shown) into the variable buoyancy chamber 7, and the seawater in the variable buoyancy chamber 7 is transferred to the seawater inlet/outlet pipe. 9 to float the water to the surface. After surfacing, confirm that air is discharged from the seawater inflow/outflow pipe 9, and then close the air supply valve 11.

e Effects of the invention As described above, the floating buoy according to the present invention has the following features:
By installing the floating fence at least in the corners where floating debris tends to accumulate, and operating the floating buoy, the floating debris can be passed through and removed, making it possible to prevent damage to the equipment. Become.

In addition, since the floating buoy has a constant buoyancy chamber above and a variable buoyancy chamber larger than the constant buoyancy chamber below, the floating buoy is maintained vertically. Even when the gas in the variable buoyancy chamber is completely replaced by liquid, a certain buoyancy force acts, so the buoy will stop at a predetermined position in the sea and will continue to float and sink. The type buoy or floating fence will not collide with the seabed, and damage to it can be prevented. In addition, the pipes for the inflow and outflow of seawater etc. that protrude from the underside of the floating buoy will not be buried in the seabed and will always be kept open, allowing smooth inflow and outflow of seawater etc. to the variable buoyancy chamber. can be done.

Furthermore, in the present invention, a pipe for supplying and exhausting gas in the variable buoyancy chamber is connected to the upper surface of the variable buoyancy chamber while passing through a robust constant buoyancy chamber connected above the variable buoyancy chamber. Because it is connected,
The robust unchanging buoyancy chamber protects the pipe connections, and even when the floating buoy is floating on the sea surface, impacts from floating objects or waves will not directly act on the pipe connections. It is possible to provide a floating type buoy that can withstand long-term use.
