Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water surface floating material recovery ship, and in particular, water surface floating material recovery for efficiently recovering floating materials such as dust floating on the water surface of rivers, lakes, harbors and coasts. It is about ships.

[0002]

2. Description of the Related Art Floating substances such as dust floating on the surface of water such as rivers, lakes, harbors and coasts not only hinder the navigation of ships but also cause environmental pollution. Various item recovery ships have been developed and used.

13 to 16 are views showing the outline of a conventional collecting apparatus for a floating surface floating material recovery ship.

FIG. 13 is a schematic diagram of a semi-submersible waste floating container water collecting apparatus, in which a waste collecting container (container) b can be moved up and down between monohulls of a catamaran (not shown). At the time of waste collection, the container b is lowered into the water, half-submerged to allow the ship to sail, and the waste is allowed to flow into the container b for storage. When a suitable amount of waste is stored, the container b is placed on board. It is something to raise. In addition, in this container semi-submersion type floating surface floating material recovery ship, there is also one in which the recovery vessel sails to the quay or the recovery base without moving the container up and down.

FIG. 14 is a schematic view of a skipper type floating material recovery apparatus, and a shows the entire recovery apparatus. A swivelable arm c is provided between the monohulls of a catamaran (not shown), and a dust collecting skipper e is provided at the tip of the arm c. When collecting dust, the arm c is swung to move the skipper. The e is lowered into the water, the water is made half-submerged, the dust is scooped up by the skipper e, the arm c is swung again, and the waste is discharged into the container b previously installed on the ship to be collected. In addition, d is a rotating shaft.

FIG. 15 is a schematic view of a bucket type water floating material recovery apparatus, and a shows the entire recovery apparatus. A guide device f for raising and lowering the garbage collection bucket g and a winch h for raising and lowering the bucket g are provided between the monohulls of the catamaran (not shown), and the bucket g is raised and lowered during the garbage collection. Lower the bucket g into the water, submerge it in the water, scoop up the garbage with the bucket g, wind up with the winch h,
The container b is discharged and collected in a container b previously installed on the ship.

FIG. 16 is a schematic view of a conveyor-type water floating material collecting apparatus, and a shows the whole collecting apparatus. A net-made conveyor l having a fin m for collecting dust is provided between the monohulls of a catamaran (not shown) so that it can be circulated and moved up and down. When collecting dust, the conveyor l is lowered and the lower part is submerged in water. The submerged and scraped trash is scraped up and circulated, and the trash is discharged into a container b previously installed on the ship to be collected.

[0008]

However, in the case of the conventional one shown in FIG. 13, when the dust is not floating, the container is raised to the surface of the sea and the container is moved to the collection area where the next dust is floating or the container is moved. I was lowering it and half-submerged in the water, and towing it to the recovery area where the next trash was floating. In the case of raising and lowering the container, when the suspended matter is not continuously suspended in the form of a strip, it is necessary to raise and lower a large container frequently, which is not preferable because the collection efficiency is poor and moreover, troublesome work is required. Further, it is not preferable that the container is towed in the water without being moved up and down, because the propulsion resistance is large and the ship speed decreases.

In FIGS. 14 and 15, the skipper and the bucket are intermittently moved to collect the dust. Therefore, while the dust is discharged into the container and collected, floating dust is moved backward. This is not suitable for collecting a large amount of dust that is flowing in a long strip along the flow of water.

In the structure shown in FIG. 16, when the waves are high or the speed of the ship is increased, dust is pushed back in front of the conveyor, and large dust does not get into the conveyor. There were various problems.

The present invention was devised in view of the above-mentioned various problems. That is, the present invention circulates a plurality of floating material recovery containers (containers) disposed at appropriate intervals between catamaran monohulls to efficiently collect dust floating on the water surface. The purpose of the present invention is to provide a floating surface floating ship.

[0012]

In order to achieve the above object, the first invention of the present invention is to dispose four sprockets vertically and horizontally at appropriate intervals on the inner skin of each monohull of a catamaran. It is possible to hang the endless chain around these sprockets so that they can circulate, and to hang the connecting material between the endless chains at appropriate intervals, and to hang the floating material recovery container on the connecting material. A chain drive device is connected to at least one pair of the above-mentioned sprockets that are suspended from each other.
