8 to 9 illustrate a second hydraulic hydrological device 400 which is a hydraulic non-powered automatic hydrological device installed at the outlet side of the discharge port 300.

Referring to the drawings, the second hydraulic system 400 is supported by the support portion 403a which is rotatably installed by the hinge means 402 on the base member 401 to support the outlet side of the drainage path 300. Second elastic means for hinge hinged between the water gate 403 having an opening and closing block 403b and the support portion 403a of the water gate 403 and the base member 401 to elastically bias toward the outlet side of the drainage path 300. 410.

The hinge means 402 has the same configuration as the above embodiment. The elastic means 410 has a similar configuration to the above-described embodiment, but the direction of the action force is different. Since the acting force of the second elastic means 410 acts on the outlet side of the drainage path 300, the acting force of the second elastic means 410 is opposite to that of the first hydraulic hydrological device 10. That is, when the water level increases, the pressure acting on the water gate increases, so that the water gate is opened while the second elastic means is compressed, and when the water level decreases, the water gate 403 is closed by the action force of the second elastic means 410.

Referring to the operation of the hydraulic hydrology according to the present invention configured as described above according to the present invention configured as described above are as follows.

As shown in FIGS. 1 and 2, when the water level rises due to a large amount of water flowing in the state of being installed at the inlet side of the water passage 200, the power and water level of the water discharged through the water passage 200 is increased. The resulting pressure acts on the blocking portion 41 of the water gate 40. Therefore, the sluice force 40 is rotated around the hinge pin 33 of the hinge means 30, the rod 53 of the cylinder 53 is compressed while the sluice 40 is a water passage 200 ) Will be blocked.

And when the inflow amount of water from the upstream is small and the water level of the water stored in the beam 100 is dropped and a part of the blocking portion 42 of the water gate 40 is exposed to the water surface as shown in Figure 7 the blocking portion of the water gate 40 ( The pressure acting on 42 and the elastic force repelling against the hydraulic pressure are increased by the cylinder 53. Therefore, the sluice gate 40 is rotated about the hinge shaft 33 to be opened, and the water is discharged through the water passage 200 and forms the fish can move the fish. That is, when the water level rises, the water overflows to the upper surface of the beam 100 so that water flows along the fish can be made, and when the water level drops, the fish is blocked, and the water passage 200 is opened to open the fish. Will be formed.

When the water passage 200 is opened by the first water gate device 10 as described above, when the water level is relatively high in the process of being discharged through the water passage 200, the water gate is installed at the outlet side of the drainage passage 300. 403 is opened to overcome the action force of the second elastic means by the hydraulic pressure acting through the drainage path (300). Therefore, the water is discharged through the drainage path 300 and the water level is lowered, so that the flow rate of the water discharged through the water passage 200 can be reduced, and further, the flow rate of the fish can be secured.

On the other hand, the opening and closing of the water passage by the water gate as described above is a torsion spring 60 or spring 72 to provide elastic force in response to the water pressure acting on the water gate 40 as shown in Figures 3 and 4 In the same manner as in the above embodiment. And as shown in Figure 5 by installing the cylinder 53 on the upper side of the beam by the link 81, it is possible to minimize the corrosion of the cylinder 53 by water.

As described above, in the first elastic means for providing a hydraulic pressure and anti-reaction force acting due to the water flow rate of the water flowing through the hydraulic water-powered automatic hydrologic apparatus and the bore channel using the same and the water level stored in the beam according to the present invention. The channel can be opened and closed automatically, so no power source or hydraulic pressure source for driving is required. In addition, at the high water level, the left and right sides of the fish can be opened to control the flow rate of the fish.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
