Description

In the case of the fishery,

The present invention relates to artificial fishes for the movement of fish in repair facilities, and more particularly, to artificial fishes which are not installed in repair facilities such as dams and underwater boats installed in rivers, To a piping type artificial fish for the movement of a fish in a repair facility for providing a method of crossing a dam of a river by using a piping to solve the problem.

In general, in order to secure water resources such as agricultural water, drinking water, hydroelectric power, etc. in the river, an underwater dam and a dam are installed in the river.

However, fishes that return to domestic waters by returning to domestic waters are such as fishes, salmon, and sweetfish. As mentioned above, if a dam is installed, the ecosystem of the underwater or dam upstream and downstream is biased because it is difficult to move the upstream reef fish to the upstream of the stream.

In other words, if the dam is not equipped with an underwater dam installed in the river, the returnable fish can not be moved upstream, and large-scale civil works should be carried out to install an artificial island in the dam.

Accordingly, artificial fishes are installed in the dam and the dam to solve the problems caused by the upstream and downstream ecological systems. More specifically, the cascade artificial fishery is installed and managed in the underwater artifacts of the river, but the stepped artificial fishery installed in the river underwater is damaged due to the lack of artificial fishery due to lack of artificial fishery when summer flood occurs. .

Accordingly, salmon, sweetfish, and yellow squirrel in salmon, swallow, and red sea have been obstructed in the repair facilities such as underwater dams and dams in the process of migrating upstream of the river, It is required to develop a technique for solving a difficult problem.

Next, the piping type artificial fishery 101 is installed in the dam of the river so that the returning fish can move across the dam and upstream of the river.

3 and 4, the piping 102 of the piping type artificial fish 101 can be formed as a spiral.

Referring to FIG. 4, in the pipeline 102, the river water flows in the direction of the arrow from top to bottom. In the pipeline 102, an inverted funnel-type flow velocity reducer 104 'is installed. Herein, the funnel-type flow velocity reducer 104 'is manufactured in a funnel shape in which the diameter of the circle on the bottom surface and the diameter of the circle on the top surface are different from each other in a cylinder in which the upper and lower surfaces are opened as a whole.

When the river water is sent from the pipeline 102 by using the submerged pump 111, the flow velocity of the pipeline 102 flows rapidly.

This makes it difficult for the returning fish to swim from the funnel inlet 104b to the funnel outlet 104c because the water pressure difference is generated in the upper side 104e and the lower side 104f of the funnel and the flow velocity is rapidly flowing to the funnel outlet 104c.

Accordingly, when a plurality of the discharge holes 104d are formed outside the funnel in the funnel-type flow velocity reducer 104 'installed in the pipe 102, the water pressure is discharged to the discharge hole 104d outside the funnel, 104e and the lower side 104f is lowered so that the returning fish can swim from the inlet 104b to the outlet 104c.

In summary, in order to solve the problem that the regressive fish swim upstream in the pipeline 102 at a high flow rate, the funnel-shaped flow rate reducer 104 'is installed inside the pipeline 102 as shown in FIG. 4, It has already been shown that the flow velocity is reduced in the water pipe 102, and the regressive fish is a favorable condition for swimming in the pipe 102.

The piping type artificial fishery 101 is characterized in that the slope of the piping 102 is reduced to reduce the flow velocity.

3B, since the flow rate of the artificial fish 101 in the piping 102 system is constant in the inlet piping 121, the inlet piping 121, the intermediate piping 122, the end piping 123, The water level inside the pipe 102 is lowered. Accordingly, if the water level of the intermediate pipe 122 and the end pipe 123 is lowered, it is difficult for the returning fish to swim in the pipe 102 and to cross the dam and move to the upstream of the river. (122) and the end piping (123) are provided with a bypass piping (110) for replenishing the amount of water.

At this time, by operating the submerged pump 112 installed in the bypass pipe, the quantity of water is supplied to the inlet pipe 121, the middle pipe 122 and the end pipe 123, and the middle pipe 122, the end pipe 123, The regenerative fish is in a favorable condition to swim inside the piping 102. As a result,

Accordingly, when the underwater pump 111 installed in the piping type artificial fishery 101 is operated, a proper amount of the river water is drained through the end pipe 123 and the radial filler 5, and the remaining amount is supplied to the underwater pump 111 The water is drained by the dam together with the river water and the returning fish through the inlet pipe 121a provided in the water direction in the branch pipe 102 on the discharge side.

3, when the funnel-type flow velocity reducer 104 installed in the piping 102 is drained off from the inlet piping 121 to the end piping 123 by the natural dropping of the dam, A safety drain pipe 108 is provided in the piping 102 to prevent the water pipe from rising, thereby automatically draining the water pipe to the radial exhaust pipe 5 in an emergency so as to lower the water pressure.

The safety drain pipe 108 has a structure in which the safety drain pipe 108 is installed one by one from a spiral pipe drop of 5 m to 10 m and a drain pipe of the safety drain pipe 108 is connected to the end pipe 123 of the pipe 102.

On the other hand, bypass piping and safety drain pipe can be omitted and the artificial language can be operated. 3A and 3B, when the internal volume of the pipe 102 is made to be a predetermined ratio, that is, the volume is constant from the inlet pipe 121 to the end water pipe 123, see FIGS. 3A and 3B And a plurality of flow velocity reduction gears 104 'are installed to manufacture and operate the artificial sounder 101.

6, the piping type artificial fish 101 is provided with windows 106 by using transparent acrylic 6 at the upper portion of the area divided by the predetermined number of times of the piping 102, 102) to move smoothly upstream of the river. That is, it is preferable that a lamp installed on a window provided on the upper part of the pipe 102 so that the regressive fish can see the light of the lamp at night to move.
