Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a floating object trapping fence and a floating object recovery device, and more specifically, the present invention relates to a floating object trapping fence and a floating object recovery device, and more specifically, the present invention relates to a floating object trapping fence and a floating object recovery device. The present invention relates to a trapping fence that can effectively trap floating objects, and a floating object recovery device that can easily collect the captured floating objects.

(Prior Art) Conventionally, there is a device as shown in FIG. 4, for example, as a means for trapping floating objects of this kind.

That is, in this conventional system, two rods 14 and 14 are erected in water, a net-like body 15 is stretched over these rods 14, 14, and floating objects 16 such as floating garbage are caught by this net-like body 15.
It is intended to be captured in conjunction with

(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 major 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, in the above-mentioned conventional one, the net-like body 15 is simply attached to the rods 14 and 14.
16 floating objects in specific water areas.
However, there is also the problem that the floating objects 16, which have been captured by the net-like body 15, may become suspended in the water body again due to the flow of water.

Therefore, the present invention aims to solve the above-mentioned conventional problems.
The purpose of this invention is to provide a trapping fence that can effectively capture floating objects such as garbage, and a collection device that can easily and quickly collect floating objects.

(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 with a flow path for water 9 between them. 6 and is installed between the front and rear parts of the outer frame 2 so as to be inclined in the vertical direction so as to catch floating objects 8 passing from the front to the rear.

Further, the outer frame 2 may be provided with a float 13 for floating the trapping fence 1.

Furthermore, floating objects 8 captured by the net-like body 4 of the trapping fence 1
A suction means may be provided for collecting.

(Function) Therefore, in the floating object trapping fence characterized by the above-mentioned configuration, the floating objects 8 washed away by the water flow are removed from the net 4...
When passing through, it is entangled with and captured by the net-like body 4..., while 2 and 5 pass through the channel 6 formed between the net-like body 4... or the net-like body 4... .

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

(Example) An embodiment 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 by several metal pipes, and reinforcing pipes 3 and 3 are installed diagonally on the upper surface of the outer frame 1. It will be done.

4... are vertical pipes 2a, 2a on the front side of the outer frame 1.
and vertical pipes 2b, 2b on the rear side, and are net-like bodies disposed approximately 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.

The floating object trapping fence according to this embodiment has the above-mentioned configuration, and the case where this is used at sea will be described next.

First, as shown in FIG. 1(0), the capture fence 1 is installed with the front side facing the direction of the ocean current (direction A).

Then, the 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 trap S1, but at this time, the floating objects 8 are caught in the net-like body 4...
It becomes entangled and captured. On the other hand, seawater 5
passes through the channel 6 formed between the net-like body 4 or the net-like body 4 . In this case, even if the net-like body 4 is clogged with the floating matter 8 captured by the net-like body 4, the seawater 5 will not flow through this channel 6.
Since the seawater 5 passes through the seawater, the seawater 5 does not stagnate.

In addition, since the net-like bodies 4 are arranged in an inclined manner, floating objects 8 or seawater 5 captured by the net-like bodies 4 are
Due to the flow of water, it is possible to prevent as much as possible from floating in the sea again.

When collecting the floating objects 8 captured by the net-like bodies 4 in this way, the small hoist boat 9 The floating matter 8 may be collected by connecting the hose 12 to the vacuum pump 11 of the work boat IO 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.

Moreover, since the trapping fence 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 1 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 necessarily necessary to configure it in this way. In short, outer frame 2
The net-like body 4 on at least two points above the net-like body 4 may be inclined in the vertical direction so as to capture the floating matter 8, and the flow path 6 for the water 5 may be 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 constructed of a metal pipe trowel, but its material, shape, etc. are by no means limited to this.

In addition, when capturing floating objects 8 mainly floating near the water surface, if floats 13 are provided on the outer frame 2 and the capturing fence 1 as shown in FIG. It can be used in a suspended state, and floating objects near the water surface can be captured effectively.

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

Further, the capture fence and recovery device according to the present invention are not limited to use at sea, but can also be applied to the ground temperature, rivers, etc.

Furthermore, the suction means for the floating matter 8 captured by the trapping fence 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 such that the net-like bodies at two points are arranged vertically so as to form a water flow path between the net-like bodies and to catch floating matter passing from the front to the rear. Since the outer frame is provided with an inclination in the direction, 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 net with trapped floating matter as in the conventional method, and a particularly remarkable effect has been obtained in that there is no need for water to stagnate.

Furthermore, since the steel body is constructed to be inclined, it also has the advantage that it can be prevented as much as possible from floating in water due to water flow.

Furthermore, if this trapping fence is equipped with a suction means, the suspended matter trapped by the net-like body can be suctioned and removed, which has the advantage that it can be recovered very easily and quickly.

Furthermore, if the trapping fence is configured with a float, it becomes possible to float the trapping fence near the water surface, and in this case, it has the unique effect of being able to particularly effectively capture and recover floating objects near the water surface. will be played.
