Description

A device {A fishway device}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing line device, and more particularly, to a fishing line device capable of artificially lifting a fish downstream of a river to send it upstream of a river.

In recent years, large-scale reclamation projects by the national comprehensive development plan or the construction of multi-purpose dams or various boats are actively proceeding.

However, if the river is installed in this way, the downstream and upstream of the river will be disconnected.

This makes it difficult for fish to climb up and down the stream and eventually changes the habitat environment of various fish inhabiting the rivers.

In particular, there has been a problem that the fish returning for the spawning can not move from the downstream to the upstream, resulting in destruction of the ecosystem of the fish.

Therefore, it is necessary to secure the fishway of fishes whose passageways are blocked by locks, beams or shutters, which is essential in the construction business. This is to restore the ecosystem, Function.

In particular, even if a dam or a reservoir is opened, even if the elevation of the dam or the reservoir is large, if the height difference between the upstream and downstream is large, the fish is difficult to safely and easily descend by the flow velocity. It is now a reality that the island has been insufficient and is endangered.

Therefore, in recent years, a variety of researches have been demanded in the field of fishes that can move fishes.

Hereinafter, a description will be given of an ADO apparatus according to a preferred embodiment of the present invention with reference to FIGS. 1 to 7D.

The device also has the technical feature of artificially lifting the fish downstream of the stream to the upstream of the stream.

Accordingly, it is possible to prevent the fish ecosystem from being destroyed due to the clogging by the beam, and the proliferation effect of the fish stock can be expected.

The apparatus also includes a lifting frame 100, a transporting unit 200, a moving body 300, a driving unit 400, and a fish receiving unit 500.

The lifting frame 100 is a supporting post on which the moving body 300 for lifting and lowering the fish receiver 500 is lifted and lowered and is installed on one side downstream of the river.

The elevating frame 100 is installed vertically upward from the downstream of the river, and includes a pair of rails 110.

That is, the moving body 300 to be described later is moved up and down along the rail 110 of the lifting frame 100.

Next, the transfer unit 200 is installed at one side of the lifting frame 100, which serves as a pipe through which the fish downstream of the river flows to the upstream of the river.

The transfer unit 200 corresponds to the upstream of the river, and includes a pipe 210 and a guide housing 220.

The piping 210 is a pipe through which the water downstream of the stream pumped up to the guide housing 220 is sent to the upstream of the stream, and is installed toward the upstream of the stream.

The shape of the pipe 210 is not limited and is preferably a hollow pipe shape connected to the guide housing 220.

The guide housing 220 collects the water downstream of the river lifted by the fish receiver 500 and sends it to the pipe 210 and is installed at the end of the pipe 210.

As shown in FIG. 2, the guide housing 220 is formed to have a width larger than the diameter of the pipe 210 to easily receive water discharged from the fish receiver 500, and a pipe 210 is formed at one end A discharge hole 221 is formed.

That is, the water lifted from the fish receiver 500 is poured into the guide housing 220 and then moved to the pipe 210 through the discharge hole 221.

On the other hand, an interference roller 222 is further provided on the bottom surface of the guide housing 220.

The interference roller 222 is preferably axially coupled to the bottom surface of the guide housing 220 as a structure for allowing the fish receiver 500 to pivot itself during the lifting of the fish receiver 500.

That is, the fish receiver 500 is lifted up to the position where the guide housing 220 is installed along the lifting frame 100 and then turned toward the guide housing 220 so that the water of the fish receiver 500 is guided to the guide housing 220, And is configured to interfere with a catching piece of a fish receiver 500 to be described later for rotation using its own weight of the fish receiver 500. [

At this time, it is preferable that the interference roller 222 is provided with a roller having a soft axis so that the rotation of the fish receptor 500 can be smoothly performed.

Next, the moving body 300 is lifted and lowered along the lifting frame 100, and the fish receiving body 500 to be described later is engaged.

That is, the fish receiver 500 is lifted and lowered along the lifting frame 100 by lifting and lowering the movable body 300.

Meanwhile, a rolling member 310 is installed on one surface of the moving body 300, that is, a surface facing the lift frame 100.

The rolling member 310 rolls along the rails 110 of the lifting frame 100 to smoothly move up and down along the lifting frame 100.

At this time, as shown in FIGS. 4 and 5, a plurality of rolling members 310 are provided on one surface of the moving body 300 and are preferably formed in a roller shape.

That is, a plurality of rolling members 310 are installed upward and downward, and guide grooves 311 corresponding to the thickness of the rails 110 are formed and can be rolled along the rails 110.

Next, the driving unit 400 generates power to move the movable body 300 along the lifting frame 100.

The driving unit 400 includes a driving motor (not shown) and includes a pulley 410 installed at the upper end of the lifting frame 100 and a wire 420 connected to the moving body through the pulley 410.

That is, when the wire 420 pulls up or down the moving body 300 by forward and reverse rotation of the driving motor, the moving body 300 is lifted and lowered.

Next, the fish receiver 500 receives the water downstream of the river and is coupled to the moving body 300.

At this time, in the process of receiving the water downstream of the river, not only the water is accommodated but also the fish in the stream downstream is accommodated.

The fish receiver 500 includes a body 510, a support frame 520, a rotation shaft 530, and a catch 540.

The body 510 constitutes the external appearance of the fish receptor 500, and is preferably constituted by a rectangular-shaped frame.

In this case, the body 510 is provided as a hexahedron type as shown in FIGS. 1 and 3. It is preferable that one surface of the body 510, that is, a surface facing the guide body 220 is formed as an inclined surface 511.

The inclined surface 511 may be inclined downward toward the inside of the body 510 from the upper end to the lower end of the body 510.

This is to make the inclined surface 511 be inclined toward the open top of the body 510 so that the discharge of water and fish through the opening is smooth.

That is, when the body 510 is rotated toward the guide housing 220, the inclined surface 511 of the body 510 may be curved so that the water contained in the body 510 can be smoothly discharged to the guide housing 220 The discharge surface is inclined so that the movement of the fish can be smoothly performed.

The upper part of the body 510 forms an opening to discharge water as described above, and the bottom surface of the body 510 is a flat surface shielded to receive water.

At this time, an inlet hole 512 is formed at one side of the bottom surface of the body 510 and an opening and closing member 513 for opening and closing the inlet hole 512 is further provided at one side of the inlet hole 512 do.

This is to allow water to flow into the body 510 through the inflow hole 512 when the body 510 descends into the water.

Accordingly, the water pressure load on the body 510 descending into the water can be relieved, and the body 510 can be smoothly descended.

At this time, the opening and closing member 513 is installed so as to rotate only upward from the bottom surface.

That is, when the body 510 is lowered, the opening / closing member 513 is naturally lifted upward by the water pressure to open the inlet hole 512. When the body 510 is lifted, The inflow hole 512 is naturally closed so that drainage of water through the inflow hole 512 does not occur.

On the other hand, the rotation angle of the opening / closing member 513 should be limited.

That is, the pivot angle of the opening / closing member 513 should be a pivot angle so that the inflow hole 512 can be closed by its own weight after the opening / closing member 513 is turned upward.

It is preferable that the rotation angle of the opening and closing member 513 is in a range of a substantially acute angle with respect to the bottom surface.

It is preferable that the circumference except for the inclined surface 511 of the body 510 is opened and the net 514 is installed so that the fish can not escape.

At this time, it is preferable that the net 514 is further formed with an attracting portion 514a so that the inflow of fish into the body 510 can be smoothly performed.

The attracting portion 514a is formed as a through hole passing through the inside of the net 514 and is formed to be gradually smaller in diameter toward the inside of the body 510 so that incentives of fish and fish can not escape.

That is, the attracting portion 514a is formed to have an inclined surface that protrudes toward the inside of the body 510 from the net 514 and has a small diameter.

The attracting unit 514a may be formed on only one of the nets 514 or the entire nets 514.

On the other hand, the net 514 is not formed entirely in the height direction on the circumferential surface of the body 510, but is installed from a position spaced upward from the lower end of the body 510.

That is, as shown in FIG. 3, the lower end of the body 510 is formed with a shielding surface 515 for preventing water from leaking out of the body 510.

If the configuration of the shielding surface 515 is omitted, the water inside the body 510 is lifted up through the net 514 when lifting up the river in the process of lifting water inside the body 510 The fish may die out of all.

That is, the shielding surface 515 is configured so that the life of the fish can be maintained inside the body 510 until the water inside the body 510 is discharged to the transfer unit 200.

The supporting frame 520 supports the body 510 together with the moving body 300 and is installed over the upper end of the moving body 300 and one side of the lower end of the body 510.

That is, the body 510 is axially coupled between the moving body 300 and the support frame 520 through a rotation shaft described later.

One end of the rotation shaft 530 is coupled to the lower end of the moving body 300 and the other end of the rotation shaft 530 is coupled to the rotation shaft 530. [ And the other end of the support frame 520 is coupled to the lower end of the support frame 520.

That is, one side of the lower end of the body 510 is axially coupled to the rotation shaft 530 so that it can be rotated toward the guide body 220 about the rotation shaft 530.

The reason why the body 510 is rotated in one direction without being rotated in the direction opposite to the rotation axis 530 is that the other end of the lower end of the body 510 is supported by a separate pedestal S.

4 and 7A to 7D, since the pedestal S protruding from the moving body 300 supports the other side of the lower end of the body 510, the body 510 can be kept horizontal at normal times And can only be pivoted toward the guide housing 220.

The locking part 540 interlocks the interfering roller 222 of the guide housing 220 with the raised body 510 to the guide housing 220 so that the body 510 rotates.

The latching part 540 is formed to extend outward from one side of the lower end of the body 510, and is preferably upwardly bent.

Hereinafter, the operation of the device having the above configuration will be described with reference to FIGS. 7A to 7D.

FIG. 7A shows a state in which the fish receiver 500 of the fishing device is locked to the downstream of the river. The body 510 may be completely locked in the river, and the open top of the body 510 may be disposed outside the river.

In this way, the water flows into the inside of the body 510 through the mesh 514 of the opening and the circumferential surface while the body 510 is immersed in the stream.

At this time, the fish may enter the inside of the body 510 through the attracting part 514a formed on the net 514. At this time, although not shown, water is supplied to the attracting part 514a, .

On the other hand, the opening / closing member 513 provided on the bottom surface of the body 510 is in a state in which the inflow hole 512 is opened by being pushed upward by water pressure, .

Next, after a predetermined time passes, water containing fish is received in the body 510 of the fish receiver 500, so that the water is transferred to the downstream of the river.

The wire 420 connected to the moving body 300 pulls the moving body 300 upward through the pulley 410. In this case,

At this time, the rolling member 310 of the moving body 300 moves upward along the rail 110 of the lifting frame 100 and the body 510 coupled to the moving body 300 is also lifted up as shown in FIG. 7B I will rise like this.

At this time, the water contained in the body 510 raised outside the stream is discharged out of the body 510 through the mesh 514. As the water pressure is released, the opening and closing member 513 is rotated by its own weight, The ball 512 is closed.

On the other hand, the water is discharged through the net 514 of the body 510, but the fish remains in the body 510 and the water level is maintained to the shielding surface 515, so that the fish condition does not become worse .

7B, when the body 510 is lifted up, the locking part 540 of the body 510 is caught by the interference roller 222 of the guide housing 220 and interference occurs.

Then, the body 510 rotates about the rotation axis 530 coupled to one side of the lower end toward the guide housing 220 as shown in FIG. 7C by the force of the upward movement.

At this time, the water inside the body 510 is discharged along the inclined surface 511 of the body 510 as shown in FIG. 7D and poured into the guide body 220.

Thereafter, the water and the fish discharged to the guide housing 220 are discharged through the pipe 210 to the upstream of the river.

On the other hand, when the water inside the body 510 is completely discharged, the operator reversely rotates the driving motor to lower the body 510.

At this time, the body 510 rotates about the rotation axis 530 in the direction opposite to the guide housing 220 due to its own weight.

Thereafter, the body 510 is supported by the pedestal S formed on the moving body 300, and then the body 510 is lowered continuously.

The opening and closing member 513 installed on the bottom surface of the body 510 is rotated by the water pressure and is turned upwards in the process of the body 510 being lowered and being immersed in the river.

Thereafter, the inflow hole 512 is opened, and the inflow of water and fish together with the net 514 is performed.

Thereafter, by repeating the above-described series of processes, it becomes possible to move the fish downstream of the stream to the upstream of the stream.

As described so far, the ADO apparatus according to the present invention has a technical feature that artificially move the fish downstream of the stream to the upstream of the stream.

In other words, it is possible to send the fish downstream of the clogged stream to the upper stream of the clogged artificial restoration, so that the ecosystem of the fish species can be prevented from being destroyed and the growth of the fish stock can be expected.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
