Description

FISH PASSAGE DEVICE FOR FRY}

The present invention relates to a fish-moving device for moving toothfish, which can freely move, such as a toothfish or a snail.

In recent years, large-scale reclamation projects based on the national land development plan, or the construction of multi-purpose dams and various beams have been very active.

By the way, in these construction activities, it is essential to secure the fishery of the fish which the moving passage is blocked by the lock, the beam or the shutter. In particular, in the case of fishes that grow and move from the downstream to the upstream, there is a reality that the fish have reached an extinction risk due to the lack of securing the fish.

Conventionally, various fish have been invented to assist the movement of such fish, such as various stepped fish passages and gentle barriers.

By the way, the above-mentioned fish movement path or the fishery, but the fish more than a certain size was relatively movable, there was a problem that the fry or snails do not go back upstream.

The present invention has been made to solve the above problems, an object of the present invention is to install a duct or a snail as the pipe is installed in the drain of the drainage lock freely bent according to the water level and the stepped tank and backflow prevention means An object of the present invention is to provide a fish-moving device for moving toothfish freely.

Features of the fish-moving device for moving the toothfish according to an embodiment of the present invention for realizing the above object, a drain port formed in the lower part of the shroud of the drainage lock, and one end is fixed to the shroud and rise and fall by buoyancy according to the water level The pipe is provided with a stepped tank consisting of a slope and freely bent at the same time, a protection net fixed to the other end of the pipe, and the opening and closing action of the drain hole as the pipe moves up and down. It is to comprise a backflow prevention means.

The above-mentioned fish movement device for larvae moving and configured as described above is freely bent according to the water level, and a very small fry, especially the eel of the eel, can be upstream even if only a small amount of water is provided by a pipeline equipped with a stepped tank and a backflow prevention means. Being able to move has the advantage of not only protecting fish stocks but also significantly increasing aquatic production.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the fish-moving fish device according to the present invention.

FIG. 1 is a schematic overall configuration diagram of a fish device for moving toothfish according to an embodiment of the present invention, and FIG. 2 is a schematic perspective view of the hydrological device in FIG.

As shown in the figure, the fish-moving fish device according to the present invention is fixed to the waterway device consisting of a hydrological device 10, a stepped water tank 21, the height can be adjusted according to the water level, and The protection net 30 is included.

The hydrological device 10 is provided with a buoyant hydrological door 12 that is supported by the hydrologic frame 11 with a triangular prism-shaped edge. In addition, the sluice door fixing roller 13 is fixed to the sluice frame to support the sluice door.

In addition, the water gate height limiting means 14 is fixed to the water frame to limit the height of the water gate.

In addition, a buoyant hydrologic gate height adjusting device 15 is fixedly installed on an upstream surface of the hydrologic gate. Here, it can be used to add a predetermined weight as the sluice gate height adjustment, it is possible to automatically adjust the height of the sluice door opening according to the weight of the weight.

On the other hand, the bottom surface of the stepped water tank 21 can be installed so as to be inclined to one side with respect to the bottom of the water channel, and in order to change the direction in which the water goes down, as a bundle of several units and arranged in a zigzag arrangement to be staggered mutually It is possible to form a tank of, and the length of the portion where these tanks are bent can be formed in a wider surface than each layer.
In addition, a cell and a cell are formed on the bottom surface of the falling part of each tank, and the cell and the bottom of the cell are formed to be connected to each other.

In this stepped water tank 21, a herb body hanger 22 is formed on the upper bottom surface of each water tank, and the herb body hanger 22 hangs over the water tank and hangs over the next water tank. Lost Here, as the herbaceous body 23, loose ropes or cloths or the like may be used, and these may be shelters or hideouts of cheerleaders.

In addition, the cascading water tank is formed up to the hydrologic gate point.

3 and 4 are schematic explanatory diagrams of a fish device for moving toothfish according to another embodiment of the present invention.

As shown in this figure, the drainage port 50 is formed in the lower part of the padding 40 of the drainage lock.

In addition, one end of the pipe 60 is free to bend is fixed to the shutter and it is possible to rise and fall by buoyancy according to the water level.

In addition, the protection net 70 is fixed to the other end of the pipe.

In addition, the backflow prevention means 80 is disposed in the conduit to open and close the drain when the conduit goes up or down in accordance with the water level.

On the other hand, a stepped water tank 61 is formed inside the pipe line 60, and the bottom surface of the stepped water tank 61 is inclined to one side with respect to the pipe line.

Effects of the fish-moving fish device according to an embodiment of the present invention as described above are as follows.

In the fish-moving device for moving toothfish according to the present invention, since the guard net 30 is fixedly installed in the sluice device 10, various foreign substances coming out from the upstream flow down into the dam mainstream or are removed by regular removal work, and so on. The foreign matters do not flow into the tank 21.

The height adjustment of the gate is controlled by the gate height adjustment, in this embodiment by attaching a weight to the gate, it is automatically adjusted by the hydraulic pressure of the gate.

Stepped water tank (21) is installed in contact with the water frame (11) and the water flowing through the water gate will flow directly into the water tank (21), at this time, the water tank (21) with respect to the bottom of the water channel As it is arranged to be inclined to one side and inclined at the same time, it is arranged in several units and arranged in a zigzag, so that the direction of water goes down can be changed, and as the water passes through, the water on the lower side is strong and the water on the high side is weak. You can choose the strength of the current (force) to move more freely.

In addition, cells and compartments are formed at the bottom of the downfall in the stepped tank 21, and the compartments and the bottom of the compartment are connected to each other, so that small fishes move upstream by reducing the intensity of the water flowing down from the stairs and the stairs. Makes it easy.

On the other hand, since the myelin sheath 23 hangs on the herb hanger 22 of the cascading water tank 21, eel and snails, including eel fry, also rely on these myeloids, making it easier to move upstream. will be.

Operational effects of the fish-moving fish device according to another embodiment of the present invention are as follows.

Since one end of the conduit 60 is fixed to the drainage port 50 formed at the lower portion of the drainage lock 40, when the water level of the upstream side is lowered, the other end of the conduit rises and the ball provided in the conduit. Backflow prevention means of the type 80 is blocked because the drain port is prevented backflow of sea water.
On the contrary, when the water level in the upstream side is increased, the backflow prevention means 80 in the conduit leaves the drain port, and at this time, the cheerfish such as the eel can move upstream along the stepped water tank 61 formed in the conduit. Will be.

In the above-mentioned device for moving fish which is constructed and operated as described above, even a very small amount of water can be freely moved upstream even with a very small amount of water by means of a hydrological position adjustable according to the water level.

Therefore, it is not only to protect fish stocks, but also to increase the production of marine products, and to provide a very useful effect in terms of economics such as greatly contributing to increasing exports of high-quality fish such as eel.
