DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for collecting suspended matter in water for collecting objects floating in the sea or the like.

[0002]

2. Description of the Related Art A recovery ship used as a means for collecting objects floating in water, such as a wide sea, approaches an object floating in water, that is, a floating object, and collects a recovery net to a target floating object. And the floating net is wrapped and collected by a recovery net.

[0003] However, when the waves are calm, a part of the suspended matter protrudes from the surface of the water, so that the suspended matter can be collected by the above-described collection method.
Since the suspended matter floating in the water falls below the surface of the water and is visible or hidden, it is difficult for the collecting vessel to approach the target suspended matter and perform the collecting operation.

[0004] Therefore, when a diver enters the recovery vessel and the recovery vessel approaches the target floating substance, the diver carries an air bag, enters the water to search for floating substances, further dives and floats. Attach an airbag to part of the underwater side of the object. Next, air is supplied to the airbag from the cylinder worn by the diver to inflate the airbag.

[0005] Then, the floating material floats on the water surface by the buoyancy of the air filled in the air bag, and the attitude of the floating material is turned sideways. When the suspended matter is exposed horizontally on the water surface, the position of the suspended matter can be easily confirmed from the collecting ship, and the collecting ship approaches the suspended matter, and the suspended matter is lifted and collected by the crane.

[0006]

However, as described above, the diver carries the airbag, goes into the water to search for floating objects, dives further, and places the airbag on a part of the underwater side of the floating objects. The mounting operation requires a high level of skill and skill because the position and posture of the floating material are not constant due to the waves.

Moreover, in order to supply air from the cylinder worn by the diver to the air bag, the diver removes his own aqualung from his mouth and supplies the air to the air bag. Again, this requires sophisticated dive techniques to put aquarangs on their mouths and is a dangerous task.

The present invention has been made in view of the above circumstances, and an object of the present invention is to safely and easily collect suspended matter floating in water without relying on a diver. It is an object of the present invention to provide an apparatus for collecting underwater suspended matter.

[0009]

According to the present invention, in order to achieve the above object, an air supply source is mounted on a boat, and a towing boat is connected to the boat via a cable. Is fixed in the longitudinal direction in the water over the longitudinal direction of. Further, an air bag which communicates with the air supply source and is supplied with air is provided at a lower end portion of the mesh body.

[0010]

When the boat is steered remotely and approaches the target floating object, the tugboat connected via the cord works in a direction away from the boat by a vertical tail that protrudes into the water from the bottom of the boat. Tension is added to the cable body, a net is stretched, and a floating object is put between the boat and the tugboat, and when the boat is steered and turns around the floating material, it is stretched vertically in the water. The netted body engulfs floating objects floating in the water. Next, when air is supplied from the air supply source to the air bag, the air bag is inflated, and the buoyancy causes the suspended matter and the net to float in a horizontal orientation on the water surface.

[0011]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an entire apparatus for collecting suspended matter in water. Reference numeral 1 denotes a boat composed of a foldable rubber boat, which is provided with a propulsion unit 2. As shown in FIG. 3, the boat 1 is equipped with a radio receiver 3 and a compressed air cylinder 4 as an air supply source.

The boat 1 is connected to one end of a cord 5 and a barge 7 is connected to the other end. Cord body 5
Is fixed to the upper edge 6a of the net body 6. This net 6
The size varies depending on the size of the suspended matter A to be recovered. For example, the width is 4 to 6 m, the vertical width is about 2 to 4 m, the mesh is about 10 cm, and the material such as synthetic fiber can be used. It has flexibility.

As shown in FIG. 2, a plurality of weights 8 are attached to the lower edge 6b of the net 6, and an airbag 9 in a contracted state is attached to one side. The air bag 9 communicates with the compressed air cylinder 4 mounted on the boat 1.

Further, a plurality of floats 10 are provided at the upper end edge of the net 6 so that the rope 5 is always located on the water surface. Upper edge 6a and lower edge 6b of net 6
A commercially available double-sided magic tape 11, 11 is attached in the lateral direction so that when the net body 6 is wound into a cylindrical shape, it can be connected to each other. Further, a plurality of reinforcing rods 12 are attached to the mesh body 6 in the longitudinal direction, and the mesh body 6 is always given tension.

As shown in FIG. 5, the cord 5 is composed of a rope 13 and an air supply tube 14, which are connected to each other by a tape or the like in a aligned state and are connected to the net 6. . And the air supply tube 14
One end is connected to the compressed air cylinder 4 via an electromagnetic valve (not shown), and the other end is routed along the upper edge and side edge of the mesh body 6 and connected to the air bag 9. When the air is not supplied, the side edges of the mesh body 6 are squashed in a flat shape, but when the air is supplied, an inflatable tube 16 which expands in a cylindrical shape is attached. 9 is connected.

As shown in FIG. 4, the tugboat 7 has a small surfboard shape, and a vertical tail fin 18 projecting into the water protrudes from a lower surface of a board 17 connected to the rope 13. The vertical tail 18 acts in a direction away from the boat 1 to apply tension to the cord 5.

The apparatus for collecting underwater floating bodies configured as described above is a crane 2 provided on a recovery boat 20 as a main ship.
1 suspended. Then, when the work of collecting the suspended matter A is started, the suspended matter A is lowered into the water from the crane 21.
A radio transmitter 22 is mounted on the recovery boat 20, and is transmitted to a radio receiver 3 mounted on the boat 1 to turn on / off the propulsion device 2, steer, and turn on / off the solenoid valve of the compressed air cylinder 4.・ Off can be remotely controlled. Next, the operation of the underwater floating body recovery apparatus will be described with reference to FIG.

As shown in FIG. 6 (a), when the recovery vessel 20 sails and finds an object floating in the water, that is, a floating substance A, the recovery device suspended by the crane 21 is lowered into the water. Then, the propulsion unit 2 is turned on by transmitting to the radio receiver 3 of the boat 1 by the radio transmitter 22. Further, the boat 1 is brought closer to the floating object A by remotely steering the propulsion device 2 by radio.

When the boat 1 is propelled, the tugboat 7 connected to the cord 5 is automatically moved away from the boat 1 by the vertical tail 18 projecting from the lower surface of the board 17 into the water. The boat 1 and the tugboat 7 are separated from each other, and at the same time, the net 6 suspended on the cord 5 is expanded. Furthermore, since the net body 6 is provided with the floats 10 at the upper edge thereof and the weights 8 at the lower edge thereof, the net body 6 becomes substantially vertical in water.

As shown in FIG. 1B, the tugboat 7 is towed by the boat 1 and travels toward the floating material A.
When the boat enters between the boat 1 and the tugboat 7, the tugboat 7 is hooked on the floating substance A. At this time, the floating substance A is floating in a substantially vertical posture in the water, and the upper end portion slightly protrudes from the water surface. Therefore, when the boat 1 turns around the floating object A while the tugboat 7 is hooked on the floating object A, as shown in the plan view and the side view in FIG. A is wound around.

Since the winding operation of the net 6 is performed in water, it is difficult to wind the net 6 around the suspended matter A.
The double-sided magic tapes 11, 11 are prevented from being connected to each other to prevent the net body 6 from being unraveled.

Next, when the transmission is transmitted from the radio transmitter 22 to the radio receiver 3 of the boat 1 and the solenoid valve is opened, the high-pressure air from the compressed air cylinder 4 flows into the inflatable tube 16 via the air bag tube 14. Is supplied to the air bag 9.

Therefore, the inflatable tube 1
Normally, when air is not supplied, the net 6 is flattened, but expands in a cylindrical shape when air is supplied. Therefore, the net body 6 wound around the floating material A is tensioned, and the floating material A It is securely bound by the body 6. Further, since the airbag 9 is filled with the high-pressure air, the airbag 9 is inflated, and the buoyancy causes the suspended matter A to float on the water surface, so that the airbag 9 is in a horizontal position with the inflatable tube 16 facing upward.

Next, as shown in FIG.
Is remotely steered by radio, and the floating material A is towed to the recovery boat 20 by the propulsive force of the boat 1. Then, as shown in FIG. 4E, the suspended matter A is suspended by the crane 21 and lifted to the recovery boat 20.

When the floating material A floating in the water is collected in this way, the boat 1 is remotely steered to wind the net 6 around the floating material A and further reduce the towing resistance from the vertical direction. Therefore, the collection operation can be automatically performed in the horizontal posture. Therefore, even in the sea where the waves are strong, the work can be done safely and efficiently without the need of a diver as in the past.

[0027]

As described above, according to the present invention, an air supply source is mounted on a boat, and a towing boat is connected to the boat via a cord, and the boat extends along the longitudinal direction of the cord. A mesh stretched vertically in water is fixed, and an air bag is provided at the lower end of the mesh, which communicates with the air supply source and is supplied with air. Therefore, when collecting suspended matter floating in water, there is an effect that the suspended matter can be safely and easily collected without relying on a diver.
