Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater suspended matter recovery apparatus for recovering an object floating in the sea or the like.

[0002]

2. Description of the Related Art A recovery vessel used as a means for recovering an object floating in water such as a wide sea is an object floating in water, that is, a floating object, and a recovery net whose target is a floating object. It collects the suspended solids by wrapping them in a collection net.

However, when the waves are gentle, a part of the suspended matter is projected from the surface of the water. Therefore, the suspended matter can be recovered by the above-mentioned recovery method, but when the waves become intense,
Floating matter floating in the water falls below the surface of the water and appears and disappears. Therefore, it is difficult for the recovery vessel to approach the target floating matter and perform recovery work.

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

Then, the floating substance is floated on the water surface by the buoyancy of the air filled in the air bag, and the posture of the floating substance is made sideways. When the floating material is exposed sideways on the surface of the water, the position of the floating material can be easily confirmed from the recovery ship, and the recovery ship approaches the floating material, and the crane lifts the floating material to recover it.

[0006]

However, as described above, the diver carries the air bag, goes into the water to search for floating matter, and further dives to put the airbag on a part of the underwater side of the floating matter. The installation work requires a high level of skill and proficiency because the position and attitude of the suspended matter are not constant due to the waves.

In addition, in order to supply air to the air bag from the cylinder worn by the diver, the diver removes his aqualung from his mouth and supplies air to the air bag, and when the air bag is inflated. , It requires a high level of diving technique to put the aqualung on his mouth again, and it is a dangerous work.

The present invention has been made in view of the above circumstances, and an object thereof is to safely and easily collect suspended matter suspended in water without relying on a diver. An object of the present invention is to provide a device for recovering suspended solids in water.

[0009]

In order to achieve the above-mentioned object, the present invention has a basket having a substantially U-shaped cross section capable of accommodating a suspended matter suspended in water, and an opening portion of the basket at the opening edge of the basket. A one-way gate that is provided so as to block the inside of the basket and allows only floating matter to enter the basket, and the air that is normally crushed into a flat shape and supplied at the opening edge of the basket. A holding tube that holds the floating material that has expanded and entered the inside of the basket and floats the floating material together with the basket, and one end is connected to both opening edges of the basket and extends outward from the opening edge of the basket. The guide nets to be output and the other end of at least one of the guide nets are connected to each other via a cord, and the net is operated to basket the suspended matter. A boat which directed towards the opening, is mounted to at least one of the boat lies in the and a air supply source for supplying air to the holding tube.

[0010]

[Operation] When the boat is remotely steered and approaches the target floating object, the floating object is caught between the two guide nets connected through the cord, and the inside of the guide net is caught. The suspension is gradually guided to the opening of the basket. A one-way gate is provided at the opening of the basket, and the one-way gate rotates inward to allow only floating matter to enter the basket. Items are held inside the basket by an expanding holding tube.
In addition, the floating force causes the floating material to float sideways on the surface of the water together with the basket.

A handle 15 is provided at one end of the vertical pipe 2a so that it can be inserted. Then, the vertical pipe 2a is pulled out so that the basket 1 is divided into left and right, and the suspended matter A collected inside the basket 1 can be taken out.

The opening edges 4 and 4 of the basket 1 configured as described above are connected to one side edge of the guiding net 20 for guiding. The size of these guide nets 20 varies depending on the size of the floating material A to be collected, but the width is 2-3 times the diameter of the floating material A, and the vertical width is 1/2 of the length of the floating material A. The mesh size is about 10 cm, and the material is flexible such as synthetic fiber.

Further, a plurality of floats 21 are attached to the upper edge of the guide net 20 and a weight 22 is attached to the lower edge thereof. The upper edge of the guide net 20 is always located on the water surface.

One end of a cord 23 is connected to the other ends of the two guide nets 20, and the other ends are connected to a boat 24, respectively. As shown in FIG. 3, these boats 24 are collapsible inflatable boats, and the propeller 25
Is equipped with. A wireless receiver 26 and a compressed air cylinder 27 as an air supply source are mounted on the boat 24. The compressed air cylinder 27 communicates with the holding tube 10 and the air bag 11 via an air hose (not shown).

The apparatus for recovering an underwater floating body constructed as described above is equipped with a crane 3 provided on a recovery ship 30 as a main ship.
Suspended by 1. Then, when the operation of collecting the suspended matter A is started, it is lowered into the water from the crane 31.

No. 4 wireless receiver 26 to drive the propulsion device 25.
Further, the propulsion unit 25 is remotely steered by radio to bring the two boats 24 close to the floating material A.

By propelling the two boats 24, the cords 23, 23 connected to the boats 24 are stretched above the water surface and the guide nets 20, 20 are expanded, and the suspended matter A is taken in between them. .

Further, since the guide net 20 is provided with the float 21 on the upper edge and the weight 22 on the lower edge, the guide net 20 is in a substantially vertical state in water and is connected to the guide net 20. The basket 1 in the water also becomes almost vertical in the water.

2B and 2C, the two boats 24, 24 are brought close to each other to bring the guide nets 20, 20 close to each other, and one guide net 20 is brought into contact with the floating material A. Then, the suspended material A is gradually guided toward the opening 3 of the basket 1.

When the guided object A approaches the opening 3 of the basket 1 and the floating object A pushes the one-way gate 5 provided in the opening 3, the rotating arm 7 of the one-way gate 5 uses the hinge portion 6 as a fulcrum. Rotate inside 1,
Floating object A pushes the rotating arm 7 and pushes away the basket 1.
Enter inside.

As shown in FIG. 2E, when the suspended matter A enters the inside of the basket 1, the rotating arm 7 of the one-way gate 5 is closed by the urging force of the urging spring 9. Even if the floating object A rotates and the floating object A presses the rotating arm 7 from the inside, that is, even if the floating object A tries to escape from the basket 1, the rotation range of the rotating arm 7 is restricted by the stopper 8. Float A cannot escape from basket 1.

Thus, the one-way gate 5 of the basket 1 only allows the floating material A to enter the basket 1,
Even if an attempt is made to exit, the contact with the one-way gate 5 prevents the exit.

When the suspended matter A enters the inside of the basket 1,

When high pressure air is supplied from 7 to the holding tube 10 and the air bag 11, they expand.

Therefore, the floating tube A is closed by the holding tube 10 while the opening 3 of the basket 1 is closed, and the floating tube A stored inside is held in the state of being pressed against the inside of the basket 1. A
The basket 1 that has captured is floated above the water surface and has a horizontal posture on the water surface as shown in FIG. here,
The rope 23 is released from one of the boats 24, and one boat 24 is remotely steered by radio, and the floating material A is towed to the recovery boat 30 by the propulsive force of the boat 24.

Then, as shown in FIG. 1F, the floating material A is hung together with the basket 1 by the crane 31 and lifted up to the recovery ship 30, and the vertical pipe 2a is pulled out by holding the handle 15 of the basket 1. The circular arc pipes 2b, 2b are divided, and the suspended matter A inside can be taken out.

When the floating material A floating in the water is thus collected, the boat 24 is remotely steered,
After the floating material A is stored in the basket 1, the operation of collecting the floating material A in the horizontal orientation to reduce the towing resistance can be automatically performed. Therefore, even when working in the sea with strong waves, it is possible to work safely and efficiently without the help of a diver as in the past. Although two boats are used in the above-described embodiment, one may be a boat and the other may be a sea anchor.
