Description

A fishery device installed in a dam that can play a role all year round even when the water level changes.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishery apparatus, and more particularly, to a fishery apparatus capable of supplying water to a fishery to enable movement of fish regardless of fluctuations in the level of dams or beams.

Generally, there are dams and beams as facilities for storing and using water flowing through rivers and valleys. However, such dams and rivers upstream and downstream of the river have a high level of step and steep incline, resulting in difficulty for fish stocks to move upstream and downstream. As a result, the ecological environment of various fish families in rivers is disturbed, and the habitat environment is severely restricted. In particular, anadromous fish returning to spawn cannot go back and upstream, resulting in the destruction of the fish ecosystem. Some problems arise.

In order to improve this problem, the fish is connected to the upper outlet to enable the movement of the fish in the dam or beam, but when the water level is lower than the upper outlet, water does not flow to the fish, there is a disadvantage that can not act as fish. .

In addition, there is a lifting and lowering type of elevator using the elevator, it costs a lot of construction, there is a disadvantage that is not easy to manage.

In addition, in the case of a high-height dam, if it is intended to have a slope of 1/20, which is a suitable slope for installing the fish, the length of the fish is too long, so it may be installed by bypassing the side of the dam. There is an excessive purchase cost and difficult management.

Due to these problems, there is currently no installation of fish on the dam, so upstream and downstream are cut off from the dam, and the river ecosystem is destroyed.

In view of this point, Korean Patent No. 0783823 discloses a four-sided dam in which a plurality of waterways having a height difference in the dam are formed in communication with the internal airway so that water can flow to the airway even with a change in the water level.

However, these four dams have a problem in that the flow rate is increased by increasing the amount of water flowing through the fish when the water level of the dam increases.

In other words, all of the waterway holes located at lower positions than the discharge water level among the waterway holes formed in the four-side dams at different heights are kept open, and the waterway holes corresponding to the discharge water level are located at the bottom of the waterway holes. The pressure of the water gradually increases and the flow rate of the water flowing over the fish can be so fast that the fish cannot be injured.The fish has a structure installed across the water hole that penetrates the dams. As it falls down, fish that have been submerged along the island are forced to be pushed near the fast-flowing waterway and discharged downstream to all four dams.

The present invention was devised to improve the above-mentioned problems, and it is possible to suppress fluctuations in the flow rate while allowing water to flow constantly to a depth that is easy for small fish to burn out in accordance with the fluctuations in the water level of dams or high beams. It is an object of the present invention to provide a device.

In order to achieve the above object, the fishery device according to the present invention is a fishery device formed in a dam or beam made of a wall to cross a bank of rivers or valleys on both sides, so that the wall can provide a movement path of the fish. A main furnace formed along the wall to flow water introduced through an upper outlet formed at an upper portion of the wall to an outer lower portion of the wall; And a shield configured to block the upper outlet port of the main furnace in case of a flood or a need.

Preferably at least formed in communication with the main furnace through the wall to supply fresh water to the main furnace at a lower position than the upper outlet of the wall when the water level of the water freshened by the wall is lower than the upper outlet. It further comprises an auxiliary sluice formed to be opened and closed one intermediate discharge hole.

In addition, the upper discharge port further includes an inlet water adjusting unit configured to adjust the amount of inflow water into the main furnace according to the water level, and the inlet water adjusting unit may adjust the open area to the upper outlet by raising and lowering the main water gate. and; One end is rotatably coupled to the main sluice extends along an upper drainage path leading to the main sway, and includes an inclined swivel plate forming an auxiliary sway between the main sluice and the main sway.

More preferably, the plurality of intermediate discharge holes are formed to have a height difference so that they can be opened and closed sequentially according to the water level.

According to the fishery apparatus according to the present invention, the water flow to the fishery can be maintained even in the water level fluctuations of the dam or the beam, while providing an advantage of stably maintaining the movement conditions of the fish regardless of the water level fluctuation.

1 to 3, the fishery device 10 includes a main fish 11 and a plurality of auxiliary floodgates 30.

The main furnace 11 receives water introduced through the upper outlet 12 formed at an upper portion lower than the upper end of the wall 20 of the bona dam formed between the banks of both sides of the river or the valley. It is formed to be inclined along the longitudinal direction of the wall 20 so as to flow into.

Reference numeral 14 is an upper drainage path leading from the upper outlet 112 to the main furnace 110.

In the illustrated example, the main furnace 11 is formed to have a flow path through which water flows from the upper left to the lower right of the wall 20. In addition, the main furnace 11 will be described later to completely close the upper outlet 112 inside the wall 20 so that the water flows through the upper outlet 112 during flooding and the dam slope is not damaged. It is formed to have an internal passage that can be closed by the dead water type main sluice 81.

That is, in the case of the wall 20 of the dam, the inner passage leading from the upper outlet 12 to the main aero 11 closes the upper outlet 12 so that water can be discharged through the main discharge gate (not shown) during a flood. The main water gate 81 of the four preventive water type to open and close the upper and lower left and right so as to be applied, and unlike the illustrated example, when applied to the wall of the beam 20, the upper outlet is open and the upper and the left and the lower are closed. Can be applied.

Here, the main sluice 81 corresponds to a shielding portion which is able to block the flood outlet or the upper outlet 112 of the main aero 11 when necessary.

Of course, on the main aero 11, an air barrier wall projecting upwardly to the bottom surface may be installed to be spaced apart from each other along an extension direction so that water flows.

The amount of water discharged through the upper outlet 12 increases as the water level rises, at which time the main air (in accordance with the water level in the upper outlet 12) is prevented from increasing the flow rate due to the increase in water and maintaining a suitable depth for the fish to burn. 11) is provided with an inflow water adjusting unit 80 to adjust the amount of inflow water.

The inflow water adjusting unit 80 includes a main water gate 81, an inclined rotating plate 82, and a hoist 90.

The main sluice 81 is accommodated in the door frame 84 in which the upper inlet 12 is formed so that the main sluice 81 is restrained on the inner wall 20a of the wall 20 to the upper outlet 12. The open area can be adjusted by lifting and lowering.

The inclined pivot plate 82 extends in a plate form along an upper drainage path 14 which is rotatably coupled by a hinge 83 at an upper end of the main sluice 81 and leads to the main aero 11. An auxiliary fishing is formed between the 81 and the main fishing 11.

The winch machine 90 is different from the example shown as being applied as an example of the elevating driving means for raising and lowering the main sluice 81 according to the water level by winding or unwinding the string connected to the upper portion of the main sluice 81. Other driving means for raising and lowering) may be applied, for example, a structure using a rack bar and pinion or a structure using a cylinder.

According to the inflow water adjusting unit 80, when the water level rises in the main sluice 81 is raised by the winch (90) and the flow rate suitable for the fish to burn the amount of discharged water discharged through the upper outlet 12 and It can be adjusted to a certain amount to maintain the depth, the inclined rotating plate 82 is the main gate 11 and even when rising to the highest point while the portion combined with the main sluice 81 as the main sluice 81 ascends It is possible to provide a ramp of 1/20 gradient in which fish can move between the main sluices 81.

Likewise, when the water level is lowered, the main sluice 81 is lowered by the hoist 90 so that the amount of discharged water discharged through the upper outlet 12 can be adjusted to a certain amount, and the inclined rotating plate 82 is the main sluice. The lower portion of the hinge 83 coupled with the main sluice 81 along with the descending of the 81 Descends continuously provides a ramp for the fish to move between the main 11 and the main sluice 81.

Preferably, the bottom of the portion of the inclined rotating plate 82 facing the main language 11, the wheel is easily installed.

The inflow water adjusting unit 80 may limit the amount of water flowing through the upper outlet 12 to a certain range to suppress the increase in the flow rate of the main gear 11 even when the water level rises.

In addition, when the main water gate 81 of the four preventive water type is applied, the main water gate 81 can be closed in case of flooding to block the discharge through the main fishery 11, and the main discharge water gate formed for the discharge (not shown). Only then can the discharge be achieved.

The auxiliary sluice gate 30 can supply fresh water to the main furnace 11 at a lower position than the upper outlet 12 of the wall 20 when the water level of the fresh water on the wall 20 becomes lower than the upper outlet 12. The plurality of intermediate discharge holes 22 formed in communication with the main furnace 11 in the inside of the dam 20 are formed to have a height difference so that they can be opened and closed sequentially according to the water level.

Here, in order to avoid the complexity of the drawings in the illustrated figure, the middle outlet holes 22 are shown to have a large difference in height between each other, but preferably, the middle outlet holes 22 are adjacent to each other in the direction of decreasing height. A portion of the discharge area of the discharge hole 22 is formed to have a height difference having an area where the discharge areas overlap with each other by occupying a part of the intermediate discharge hole 22 of the previous order.

On the main furnace 11 corresponding to the position where the intermediate discharge hole 22 is formed, a retention tank 15 formed to be drawn downward so that fish can stay there is formed.

The auxiliary sluice gate 30 is moved up and down along the housing 32 formed on the inner surface of the wall 20 on the opposite side of the main furnace 11 to close and open the intermediate discharge hole 22 by being closed by a winch. It is installed to be adjustable.

In the illustrated example, two auxiliary sluices 30 are disposed at different heights in order to avoid the complexity of the drawing, but the number of the auxiliary sluices 30 is expanded or reduced depending on the size and height of the wall 20 to be applied. Of course you can.

This auxiliary sluice 30 can be configured to open and close the intermediate discharge hole 22 in a variety of ways.

For example, the auxiliary gate 30 is raised and lowered by a winch (not shown) or a cylinder (not shown) to adjust the opening / closing area of the intermediate discharge hole 22 or automatically applied by buoyancy when applied to the beam. Can be opened and closed.

Therefore, by selectively opening the auxiliary sluice 30 to be opened correspondingly to the water level according to the water level of the wall 20 in order according to the water level, and adjusting the open area, even if the water level of the dam is lowered, a certain amount of water on the esophagus Can be used to move fish along the main island (11) throughout the year.
