And a spring 10b which is arranged in the guide member 10 and biases the pin 16 with respect to the shaft 6 in the insertion direction.

The opening means is attached to the electromagnetic coil 16a fitted on the body of the pin 16 at a predetermined position above the columns 2 and 2, and detects the arrival of the sliding members 3 and 3. It is composed of a detection switch 18 (see FIG. 1) for energizing the electromagnetic coil 16a.

The upper portions of the columns 2 and 2 are projected upward from the side wall 1A of the waste storage box 1, and the upper portions of the columns 2 and 2 are guide plates 19 which are inclined downward toward the rear inside the waste storage box 1. Is fitted to the end of.

Further, as shown in FIGS. 4 and 5, the river downstream side wall 20 of the waste storage box 1 is configured to be movable up and down via the guide portion 21 of the waste storage box 1, and the waste storage box 1 is provided.
When the waste 4 is sufficiently collected therein, the waste 4 is moved downward to open the downstream side of the waste storage box 1 so that it can be transferred to a waste collection ship (not shown). Further, the bottom wall of the waste storage box 1 is inclined rearward so that the waste 4 stored in the waste storage box 1 can be easily taken out.

In the above structure, as shown in FIGS. 1 and 2, first, the refuse storage box 1 is fixed to the riverbed B by the mooring line R. Then, the net body 8 is set in a substantially horizontal state in a dust collecting posture Y in which the net body 8 is sunk below the water surface. Then, the dust 4 flows from the upstream of the river, and the dust 4 is collected in the curved portion of the net body 8.

Then, when an appropriate amount of garbage 4 is collected,
The winch motor 11 is driven to bring the net body 8 into the dust throwing posture Z. Then, the wire 13 drives the driving drum 1.
Since the shaft rod 6 is wound around the rods 2, 12 and is in a non-rotatable state by the insertion of the pin 16, the shaft rod 6 is slidable by the sliding members 3, 3 while the net body 8 is kept in the dust collecting posture Y. It is guided by the stanchions 2 and 2 and goes up.

When the sliding members 3 and 3 move up to a predetermined position on the columns 2 and 2, the detection switch 18 detects and operates them to energize the electromagnetic coil 16a, and the pin 16 causes the elasticity of the spring 17. The shaft rod 6 is pulled out against the shaft rod 6, and the shaft rod 6 becomes rotatable.

By further winding the wire 13,
The wire 13 wound around the elevating drum 15 is pulled to rotate the elevating drum 15, the shaft 6 rotates accordingly, and the net body 8 rotates to the dust storage box 1 side. Figure 4
As shown in FIG. 3, the dust 4 is dropped from the net body 8, and the dust 4 is guided by the guide plate 19 and thrown into the dust storage box 1.

When the net body 8 is returned to the dust collecting posture Y again, the winch motor 11 is reversely rotated and the wire 13 is led out from the drive drums 12, 12. Then, the net body 8 in the dust throwing posture Z rotates in the opposite direction (upstream of the river) due to its own weight, and the wire 13 moves the wire 13 up and down.
The net device 5 is wound around this by the rotation of 5
The whole starts to descend, the detection switch 18 stops operating, the pin 16 engages with the end of the shaft rod 6 again, the shaft rod 6 cannot rotate, and the net device 5 further descends. The net body 8 is submerged in the water to be in the dust collecting posture Y, and the net body 8 is ready to collect the dust 4.

When a proper amount of dust 4 is collected in the net body 8, the net body 8 is again placed in the dust throwing posture Z as described above, and the dust 4 is thrown into the waste storage box 1. By repeating such operations, the waste 4 that has flowed from the upstream of the river is collected, and when the waste 4 is sufficiently collected in the waste storage box 1, the side wall 20 is opened and the waste 4 is collected. Then, it is transferred to a predetermined place and processed.

As described above, according to the embodiment of the present invention, by setting the net body 8 in the dust collecting posture Y in which the net body 8 is located below the surface of the water, the dust 4 is easily collected in the net body 8 by the transportation force of the river. Since the net body 8 holds the dust collecting posture Y by the fixing means while the net body 8 is raised along the columns 2 and 2 when the lifting / lowering device 9 is driven, the net body 8 is collected. The dust 4 can be scooped from the water surface without dropping, and when the net body 8 rises to a predetermined height, the shaft 6 can be turned by the opening means, and the net body 8 turns to the dust storage box 1 side. The dust throwing posture Z is set, and the dust 4 can be thrown into the dust storage box 1.

Further, according to the embodiment of the present invention, since the garbage 4 is collected in the river before it flows into the ocean, it is not necessary to collect the garbage 4 over a wide area on the sea. It is possible to improve, and it is possible to surely prevent the marine pollution as compared with the case where the waste 4 that has flowed into the ocean is collected by a garbage collection ship.

Further, since the waste storage box 1 has a floating structure floating on the river, the installation depth of the net body 8 in the waste collecting posture Y can be kept constant regardless of the change in the water level of the river. Sampling can be performed reliably, and because the floating structure suppresses the run-up of waves from the ocean side, a quiet water area can be formed on the upstream side of the river in the garbage storage box 1, so the garbage 4 moves violently. The waste 4 can be easily collected by suppressing the above.

Further, by making the waste storage box 1 have a floating structure which floats on the river, it does not affect the flow of the river, and therefore it is possible to prevent adverse effects on the ecosystem.

[0025]

As is apparent from the above description, according to the present invention, by placing the net body in the dust collecting posture, the dust can be easily collected in the net body by the carrying force of the river. When the hoisting and rotating device is driven, the dust collecting posture is maintained by the fixing means while the net body is being raised along the column, so the collected dust can be scooped without dropping, and the net body can reach a predetermined height. When it rises, it can be rotated by the opening means and rotates to the box side to enter the dust throwing posture,
Garbage can be thrown into the box.

Further, according to the present invention, since the waste is collected in the river before it flows into the ocean, it is not necessary to collect the waste over a wide area on the sea, and therefore the collection rate of the waste can be improved. Compared with the case of collecting the waste that has flowed into the ocean with a garbage collection ship, it is possible to reliably prevent marine pollution.
