Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for removing debris floating with oil at the front of an oil recovery device when oil is recovered by an oil recovery vessel.

Despite strict regulations under the Marine Pollution Prevention Act, oil spills and oil spill accidents continue to occur in the ocean, and plans to build oil recovery vessels have been actively carried out in recent years.

When recovering oil using an oil recovery vessel, it is necessary to remove debris floating with the oil in advance so that it does not become an obstacle during oil recovery.

There are various conventional floating debris removal devices as shown in FIGS. 1 to 4.

In the floating debris removal device shown in Figure 1, a wire mesh frame a is placed on the water surface and floating debris is blocked by a wire mesh b to prevent the debris from flowing into the oil recovery vessel. If the oil accumulates, it will also prevent the oil from flowing to the oil recovery vessel.
Garbage must be removed at the input.

The floating debris removal device shown in Fig. 2 has a wire mesh frame a pivoted with pins,
When the wire mesh b is full of debris, the wire mesh frame a is manually rotated upwards, but when the wire mesh frame a is raised upwards, the debris flows into the recovery device of the oil recovery vessel along with the oil. Put it away.

The floating debris removal device shown in Figure 3 has a wire mesh frame a in the form of a packet, which is pivoted with pins and rotated by power. , the garbage flows into the recovery equipment along with the oil.

The floating garbage removal device shown in FIG. 4 continuously removes garbage using a conveyor d having a wire mesh belt c, but because of its complicated structure, it is prone to breakdowns and increases costs.

The present invention has been made to eliminate the drawbacks of the conventional floating debris removal device described above, and to remove floating debris that is not intended to flow into the oil recovery device together with the oil before the oil recovery device. One end of the lower frame, which is rotatably formed by an appropriate means, is pivoted to an appropriate position on the ship, and a bottom frame support is attached at an appropriate position extending in the longitudinal direction of the ship from the pivot position of the lower frame. One end is pivotally attached, and a bottom frame having a mesh member to prevent floating debris from flowing out is pivotally attached to the other end of each of the lower frame and the bottom frame support, and the lower frame and the bottom frame support are pivoted. A link mechanism is formed by the bottom frame and the bottom frame support, and an upper frame formed into a packet shape by a mesh member is connected to the lower frame on an arm pivoted on substantially the same axis as the rotation center of the lower frame. This invention relates to a floating debris removal device for an oil recovery vessel, characterized in that the device is installed so as to be supported by the oil recovery vessel.

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

A bracket 14 is fixed to an appropriate position below the lower frame 6, and an arm 16 is attached to an axial center line that is substantially the same as the axial center line of the pin 5 via a bracket 15 or a pin (not shown). Floating debris 17 is placed at the tip of the arm 16.
An upper frame 19 formed into a packet shape with a wire mesh 18 is provided to make it easier to scoop up the food.

Furthermore, the upper frame 19 can be supported by the lower frame 6 as shown in FIGS. 6 and 9, and the bottom frame 8 has a single cylinder 2.
A wire mesh 20 is placed over the entire inner width of the gap.

One end of the lower frame lifting wire 21 is fixed to an appropriate position at the tip of the lower frame 6, and the other end of the lower frame lifting wire 21 is provided on the connecting member 9 via the wire guide sheave 22 on the starboard side. A wire hook 26 is fixed to the lifting winch 23 on both sides, and is used to hang the underside stopper 24 and one end of the upper frame lifting wire 25, and a dust collection basket 27 is installed on the connecting member 3.
Further, the other end of the upper frame hoisting wire 25 is fixed to a lifting winch 29 provided on the port side of the catamaran 1 through a wire guide sheave 28 provided on the catamaran 1.

In the figure, 30 is a storage stopper, 31 is an overwinding prevention stopper, 32 is a bracket for fixing the lower frame lifting wire 21, 3
3 indicates an oil recovery device, and 34 indicates oil floating on the sea surface.

When recovering oil by catamaran 1, floating debris 17
must be removed from the oil 34.

First, the lifting winches 23 and 29 are operated to position the lower frame 6, upper frame 19, bottom frame 8, and bottom frame support 12 as shown in FIG.

Oil 34 and floating garbage 1 flowing into the upper frame 19 on the sea surface
7 reaches the 19th part of the upper frame.

Then, since the upper frame 19 is formed into a packet shape with the wire mesh 18, the oil 34 passes through the mesh of the wire mesh 18 and flows out to the oil recovery device 33, but the floating debris 17 is removed from the upper frame 1.
9 and does not flow out to the oil recovery device 33 side.

When a suitable amount of floating debris 17 has accumulated in the upper frame 19, the lifting winch 23 is operated to wind up the lower frame lifting wire 21.

Then, the lower frame 6 rotates upward around the pin 5, and on the other hand, since the upper frame 19 is supported by the lower frame 6, the upper frame 19 is pushed upward by the lower frame 6, and the upper frame 19, The arm 16 also rotates upward around the pin 5 integrally with the lower frame 6.

When the upper frame 19 reaches the position shown by the solid line in FIG. 6, the bracket 14 of the lower frame 6 and the lower frame stopper 24 are connected by appropriate means (pins in this embodiment).

When the lower frame 6 and the upper frame 19 rotate upward, the bottom frame 8 is rotated upward by the lower frame 6 around the pin 13, and the lower frame 6
When the upper frame 19 reaches a predetermined position, the wire mesh 20 attached to the bottom frame 8 stands approximately upright on the water surface.

When the upper frame 19 is raised to a predetermined position by the lower frame 6, the upper frame lifting wire 25 is removed from the wire latch 26 and the upper frame 19 is lifted up.
Then, the upper frame lifting wire 25 is wound up by the lifting winch 29.

Then, the upper frame 19 rotates upward about the same axis as the pin 5 (see FIG. 7), but the lower frame 6, the bottom frame 8, and the bottom frame support 12 rotate as shown in FIGS. 6 and 7. Since the state remains as shown by the solid line, the floating debris 17 flowing in is blocked by the wire mesh 20 provided on the bottom frame 8 and does not flow out to the oil recovery device 33, but the oil 34 passes through the wire mesh 20. It can flow out to the oil recovery device 33 side.

When the upper frame 19 is rotated upward, the upper frame 19 interferes with the overwind prevention stopper 31 as shown in FIG. 7, and at this position, the dust is discharged into the dust collection basket 27.

When the discharge of the garbage into the dust collection basket 27 is completed, the upper frame lifting wire 25 is let out from the lifting winch 29 and the upper frame 1
9 to the position shown in FIG. Then, the lower frame hoisting wire 21 is let out from the hoisting winch 23 to rotate the lower frame 6, upper frame 19, and bottom frame 8 downward, and the state shown in FIG. 5 is returned to the state shown in FIG. Floating debris 17 is removed.

By repeating the above operations, the floating debris 17 can be removed from the oil 34 without flowing out to the oil recovery device 33.
7 can be completely removed.

When the work is completed, the lower frame lifting wire 21 is wound up and the state shown in FIG. 19, remove the lower frame lifting rope 21 from the lower frame 6, hook it on the bracket 32, and then attach it to the lower frame 6.
The upper frame marking wire 25 is wound up while the upper frame 19 is connected to the upper frame 19 by an appropriate means.

Then, the lower frame 6, the upper frame 19, the bottom frame 8, and the bottom frame support 12 rise to the state shown in FIG. 8.

Then, the storage stopper 30 and the bracket 14 of the lower frame 6 are connected with pins, and the storage of the floating debris removal device is completed.

Once the floating debris removal device has been stored, the lower frame 6 and upper frame 1
9. Since the bottom frame 8 and the bottom frame support 12 are completely separated from the sea surface, they do not provide resistance to the movement of the catamaran 1, and therefore the catamaran 1 can proceed smoothly. .

In the embodiments of the present invention, the case where the floating garbage removal device is used on a catamaran ship has been described, but it can also be applied to barges that require crossing, and it can also be applied to cleaning vessels dedicated to garbage. It goes without saying that it is also possible to employ a hydraulic cylinder or a pneumatic cylinder other than a winch as the lifting means, and that various other changes can be made without departing from the gist of the present invention.

Since the floating debris removal device for an oil recovery vessel according to the present invention has the above-described configuration, (■) Floating debris larger than the mesh of the wire mesh is completely blocked by the wire mesh on the top frame or the bottom frame, so floating debris is The oil does not flow into the oil recovery device, so even when removing floating debris, oil recovery operations can be carried out continuously without stopping.

(■) The structure is very simple, there are few failures, it is advantageous in terms of maintenance, and the manufacturing cost is low.

(■) Since the entire equipment can be stored on the upper deck, there is less propulsion resistance except during oil recovery work, and it is possible to increase the speed of the ship, resulting in good work efficiency.

(■) Devices that have parts that constantly rotate underwater, such as conveyor-type collection devices, agitate surface oil that floats and flows in, but the device of the present invention completely blocks out floating debris. There is no need to stir the surface oil.

(■) Since a link mechanism is formed by the bottom frame, bottom frame, and bottom frame support, when the bottom frame rotates upward, the bottom frame pivots with the bottom frame support even without any other drive mechanism. It always rotates upwards around the landing point, and the wire mesh attached to the bottom frame automatically becomes erect.

Therefore, there is no malfunction in which the wire mesh provided on the bottom frame is not in the position for removing dust even though the lower frame and the upper frame are raised, and highly reliable work is possible.

(■) As the lower frame supporting the upper frame is rotated upward and the wire mesh is erected at the same time using a link mechanism, the structure is simple, and there is no need for an extra drive or control device, so the price is low. is cheap.

etc., exhibits various excellent effects.
