Abstract

The present invention relates to a hydrological device for fish piping system for dam damage of fish, to minimize the amount of water discharged from dams, estuaries, or reservoirs through the fish, and to reduce or drop the fish through the fish regardless of the size of the drop. It is an object of the present invention to provide a means for maintaining a low flow rate in the fish to be safe and easy.

To this end, the hydrological device mounted on the airway piping system is in the form of a cylindrical single tube, and the inner wall of the single tube forms a partition with wings projecting inwardly, and the oil-driving pipe fixed in the oil-and-water pipe and both ends of the oil pipe The inflow and outflow ports are formed at the center, and the openings for upstream and downstream disks are arranged diagonally with each other. A screw is driven while flowing inside the water pipe to rotate the rotary opening at a constant speed. Fish entering the hydrologic device through the downstream fish passing opening rotate the rotating opening 180 degrees and then through the upstream fish passing opening. It is configured to be burned upstream.

Since the flow rate is small and the flow of water is slow, it is possible to safely and easily catch and drop the fish, and the construction cost and operation cost of the facility are reduced.

Description

Water-on / off Watergate Device for Fishway Piping System}

The present invention relates to a hydrological device mounted on an estuary that is installed for dams and small drops of fish between upstream and downstream of a dam, an estuary bank, or a reservoir. A repetitive cross-opening type hydrological device

Generally, when the waterway is blocked by dam, estuary bank, or reservoir lock, the fish can make a separate waterway for the descent of the fish from the upstream to the downstream or the small stream of the fish from the downstream to the upstream. Even if the flood gates are opened, if the upstream and downstream downfalls of dams, estuaries or reservoirs are large, the flow rate is very large, which makes it difficult to safely and easily destroy fish. It is designed to reduce.

For this reason, conventional fisheries are largely divided into channel-type fish, including lock-type fish, lock fishes, and pipe fishes, including planar, ferrous, and cascading.

Republic of Korea Utility Model Publication No. 1999-0041787 and Patent Publication No. 2001-0016199 present an adobe block or dropping hole to reduce the flow rate on the inclined waterway of the channel, the patent registration number 1991-0000106 US Patent No. 4,629,361 relates to a piped airway system.

In the case of aqueducts, various measures have been proposed to reduce the flow rate due to free fall, and since a very long flow path is required to maintain a gentle slope, a zigzag structure may be used for this purpose. Due to the enormous cost of construction of the structure, it is difficult to provide sufficient facilities, while the amount of flowing water is lost and it is not easy to expect a satisfactory flow rate reduction effect. There is a disadvantage in that the installation of power equipment, supply of power, and maintenance of operating manpower are required, and the amount of running water lost during the operation of the lock is large, and the conventional piped fish is mainly flow rate due to the drop between upstream and downstream. Of long length starting at the far end of the dam and ending at the far end to reduce The bar consists of a pipe system is that the installation cost.

The problem of this invention is

First, the installation and operation of the air piping system is possible regardless of the inclination of the pipe, thereby enabling vertical installation of the air piping system, thereby minimizing its installation space, its length and installation facilities.

Secondly, it is to make the descent and small stream of fish including fish species with low swimming ability easy and safe by slowing the flow rate in the fishing pipe system.

Third, to minimize the amount of running water to minimize the loss of water,

Fourth, to minimize the size and simplification of the facility, and to be automatically driven by the minimum flow without the need for a separate driving device or power source, there is no need for an operator of the driving device and there is no need for maintenance. Minimize operation and maintenance costs.

As shown in FIG. 5, the flow diagram of the fish piping system, the water flowing from the dam, the estuary bank, the reservoir, or the upstream reservoir 11 connected therefrom and having the same water level 12 is the upstream fish pipeline 13 of the hydrologic device. And a shutoff valve 14 to the hydrologic device 10 of the present disclosure, the downstream of which is connected to the open water downstream of the downstream through the waterway pipe 15 of the hydrologic device, and the drop corresponding to the head height under atmospheric pressure. If it exceeds 10 meters, it is connected to the downstream intermediate reservoir.

As shown in the exploded view of FIG. 1 and the longitudinal cross-sectional view of FIG. 2, the main body 1 of the sluice device is a cylindrical single tube, which is composed of a plurality of small perforations in the center of its upstream side, or a net in the opening. The upstream disk (2a) having an upstream inlet (7a) between the central portion and the circumference of the disk and the upstream disk fish passage opening (6a) between the central pipe and the periphery of the disk to separate from the end pipe To the upstream side of the water pipe (3), and to the downstream side of the center and the disk having an oil outlet (7b) to prevent the inflow of fish by forming a plurality of small perforations in the center or by forming a net in the opening Between the perimeter, the downstream disc 2b having the downstream disc fish passing opening 6b is oriented so that the two openings 6a and 6b are positioned diagonally to each other so as to be separated from the short pipe. It is fixed to the downstream side of the leading pipe 3.

As shown in FIG. 2, longitudinal cross-sectional view and FIG. 4, cross-sectional view, the inner wall of the main body 1 is fixed with the wing 4 which protrudes adjacent to the outer wall of the water pipe 3 so that a clearance may be minimum, and a small flow pipe (3), the integral rotation formed by the spiral screw 5 fixed to the inner wall of the oil pipe 3 and the upstream disk 2a and the downstream disk 2b fixed to both ends of the oil pipe 3. The opening 8 is freely rotated inside the blade 4 about the ends of the water pipe 3.

As shown in FIG. 5, an upstream side of the hydrological device 10 is connected to an upstream side of the dam through an air pipe under a water level 12 of a reservoir 11 connected to a dam, an estuary bank, a reservoir or a water level thereof. In the sluice device 10 connected downstream of the water or intermediate reservoir 17 below the water level 16 through the air pipe, the water flowing into the upstream disc flow pipe inlet 7a of FIG. 3) The rotary opening 8 composed of the screw 5, the water pipe 3 and the upstream disc 2a and the downstream disc 2b while passing through the screw 5 fixed to the inner wall thereof. It drives and rotates and flows downstream of the hydrologic apparatus 10 through the downstream disc flow pipe outlet 7b.

The water flowing into the sluice device 10 from the upstream by the free fall through the fish passage opening 6a of the upstream disk is discharged from the upstream pipe 3, the upstream disk 2a, the downstream disk 2b and the wing ( 4), the flow is blocked, but a small part of the quantity is released downstream through the gap to the fish passing opening 6b of the downstream disk. These runoff flows into and out of the fishery piping system and acts as a attractant to attract fish that want to descend from the upstream and fish that wish to be injured from the downstream to the fishery piping system.
