Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention comprises a floating matter capturing shelf, a floating matter collecting device,
More specifically, there is a trapping shelf that can effectively capture floating objects such as garbage and seaweed fragments floating in the water or on the water surface, and a floating object trap that can easily collect the captured floating objects. Regarding a collection device.

(Prior Art) Conventionally, as a means for trapping floating objects of this kind, there exists, for example, the one shown in FIG. 3.

That is, in this conventional method, two rods 14,
14 is erected, a net-like body 15 is stretched around these rods 14, 14, and floating objects 16 such as floating garbage are entangled and captured by this net-like body 15.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional means is used by arranging the net-like body 15 so as to be insulated from the water, floating objects 16 captured by the net-like body 15 may This has caused a serious problem in that the body 15 becomes clogged, which obstructs the flow of water and causes water to stagnate, thereby adversely affecting the surrounding water area.

In addition, since the above-mentioned conventional method simply stretches the net 15 over the rods 14, 14, it is only possible to prevent the floating objects 16 from flowing out into a specific water area, and furthermore, the floating objects 16 that are once captured by the net 15 can only be prevented from flowing out into a specific water area. There was also the inconvenience that the floating objects 16 would float again in the water area due to water flow or the like.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide a trapping shelf that can effectively catch floating objects such as garbage, and to easily and quickly remove the floating objects. The object of the present invention is to provide a collection device capable of collecting data.

(Means for Solving the Problems) That is, in order to solve the above-mentioned problems, the present invention provides two or more mesh bodies 4...
It is constructed between the front and rear portions of the outer frame 2 so as to form a flow path 6 for water 9 therebetween and to be inclined in the vertical direction so as to capture floating objects 8 passing from the front to the rear. The outer frame 2 is provided with a float 13, which is a shelf for catching floating objects. Further, a suction means for collecting the floating matter 8 captured by the net-like body 4 of the capturing shelf 1 may be provided.

(Function) Therefore, in the floating object trapping shelf characterized by the above-mentioned configuration, since the float 13 is provided on the outer frame 2, the trapping shelf floats near the water surface, but due to the water flow. Floating objects 8 that have been washed away are net-like bodies 4
While passing through the net-like bodies 4, the water 5 is entangled with and captured by the net-like bodies 4, while the water 5 passes through the channels 6 formed between the net-like bodies 4, or the net-like bodies 4.

The floating matter 8 thus captured by the net-like body 4 is collected by a suction means.

(Example) An example of the present invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 2 denotes an outer frame formed into a substantially rectangular parallelepiped shape with several metal pipes, and reinforcing pipes 3, 3 are installed diagonally on the upper surface of the outer frame 2. It will be done.

4... are vertical pipes 2a on the front side of the outer frame 2,
2a and the vertical pipes 2b on the rear side, which are arranged substantially parallel to each other at predetermined intervals and inclined in the vertical direction to form a flow path 6 for seawater 5 between the vertical pipes 2b, 2b. One end side 4b is provided so as to be at the same height as the other end side 4a of the upper net-like body 4. Reference numeral 7 denotes a lifting hook attached to approximately the center of the reinforcing pipe 3 of the outer frame 2. 13 is a float attached to the upper outer frame 2 at a predetermined interval, and a weight or the like (not shown) is attached to the lower pipe of the outer frame 2, so that the catching shelf can be carried away by the water flow etc. It is constructed so that it floats near the water surface without being blown away.

The floating object trapping shelf according to this embodiment has the above-mentioned configuration. Next, the case where this is used at sea will be explained.

First, if the capture shelf 1 is sunk into the sea with its front side facing the direction of the ocean current (direction A) as shown in Figure 1B, the outer frame 2 will be provided with floats 13. , the capture shelf 1 will float near the sea surface.

Floating objects 8 such as garbage and pieces of seaweed floating in the sea or on the sea surface are swept away by the ocean current and pass through the trapping shelf 1. At this time, the floating objects 8
will be entangled with the net-like body 4 and captured. On the other hand, the seawater 5 passes through the channel 6 formed between the reticulated bodies 4 or the reticulated bodies 4. In this case, even if the net-like body 4 is clogged with floating matter 8 captured by the net-like body 4, the seawater 5 will pass through this channel 6, so the seawater 5 does not stay there.

In addition, since the net-like bodies 4 are arranged at an angle, there is no possibility that the floating objects 8 captured by the net-like bodies 4 will float in the sea again due to the flow of seawater 5. It can also be prevented as much as possible. Incidentally, even if the direction of the sea current is opposite to the direction A, the floating objects 8 can be captured on the back side of the net-like bodies 4 .

When the floating objects 8 captured in the net-like body 4 in this manner are recovered, a small hoist boat 9 is used to collect the floating objects 8 through the hooks 7 attached to the outer frame 2, as shown in FIG. In the lifted state, the floating matter 8 may be collected by connecting the hose 12 to the vacuum pump 11 of the work boat 10 to remove the floating matter 8 by suction.
By performing this collection work periodically, it is possible to prevent the net-like bodies 4 from clogging.

In this way, a series of operations for capturing and recovering the floating objects 8 can be performed extremely quickly and easily.

Furthermore, since the catching shelf 1 has a simple structure, it has the advantage that the entire structure can be made lightweight and that it can be easily installed and removed.

Note that the specific number of mesh bodies 4 provided in the outer frame 2 is not limited, and the design can be changed arbitrarily depending on the purpose of use, usage, etc.

Further, in order to capture the floating objects 8 well, it is necessary to arrange one end side 4b of the net-like body 4 at the same height as the other end side 4a of the net-like body 4 disposed above, as in the embodiment. Although desirable, it is not necessary to configure it this way. In short, at least two or more net-like bodies 4 are provided on the outer frame 2 so as to be inclined in the vertical direction so as to capture floating objects 8, and a flow path 6 for water 5 is formed between the net-like bodies 4. The specific angle of inclination does not matter.

Further, in the above embodiment, the outer frame 2 is made of a metal pipe, but its material, shape, etc. are by no means limited to this.

Furthermore, it is of course possible to use a plurality of capturing shelves 1 according to the present invention, and the specific manner of use thereof is not limited.

Furthermore, the trapping shelf and recovery device according to the present invention are not limited to use at sea, but can also be applied to other locations such as lakes and rivers.

Furthermore, the suction means for the floating matter 8 captured on the capturing shelf 1 is not limited to the vacuum pump 12 as in the embodiment.

Other specific configurations such as the shape of the net-like body 4 can also be changed as desired within the scope of the present invention.

(Effects of the Invention) As described above, the present invention is characterized in that two or more net-like bodies form a water flow path between the net-like bodies and are arranged vertically so as to capture floating objects passing from the front to the rear. Since the outer frame is provided on the outer frame at an angle, floating matter is captured by the net-like bodies, while water passes through channels formed between the net-like bodies.

Therefore, there is no inconvenience such as clogging of the mesh body with trapped floating matter as in the prior art, and a particularly remarkable effect has been obtained in that there is no need for water to stagnate.

Furthermore, since the net-like body is constructed in an inclined manner, it also has the advantage of being able to prevent the net-like body from floating in water again due to water flow as much as possible. moreover,
The outer frame is provided with a float so that the capture shelf itself can float near the water surface, so when using it, the capture shelf only needs to be submerged in the water, and is portable. It also has the practical effect of being applicable regardless of location.

Furthermore, when this trapping shelf is equipped with a suction means, the suspended matter trapped by the net-like body can be suctioned away, and the collection can be carried out extremely easily and quickly.
