Description

Fish PASSAGE DEVICE AND FISH PASSAGE BLOCK}

The present invention mainly installs an elevator that can freely move up and down on the front of a dam installed in a river or a large river, so that various fishes can move freely from downstream to upstream, so construction and management are easy and all costs are high. The present invention relates to a fishery device and a fish block configured to enable a significant reduction in the number of fish, as well as to enable a natural movement of fish in a channel fish.

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

The essential consideration in this construction project is to secure the fishery of fish that are blocked by the locks, beams, and shutters, which can restore the ecosystem and proliferate fish stocks. Will perform.

In particular, even if the waterways of dams or reservoirs are opened, the estuary has a characteristic that it is difficult for the fish to be safely and easily destroyed by the flow rate if the upstream and downstream of these streams are large. The current situation is that the lack of secured fishery is endangered.

Conventional fishes can be roughly classified into locked and piped fish, including waterways.

In the case of the waterway type fishery, since it should be constructed in a structure having a zigzag-type gentle slope to reduce the flow velocity due to the drop, it requires a large space as a whole and requires a huge cost, as well as a large amount of flowing water is very satisfactory. It is difficult to expect a function as an adobe.

In addition, the lock type fish requires the installation of the lock and the installation of power equipment for its operation, the supply of power and the maintenance cost during operation, and has a disadvantage in that the amount of flowing water lost during the operation of the lock is large.

In addition, the piped fishing vessels have a difficulty in carrying out the entire length from the upstream to the downstream of the dam in order to reduce the flow rate mainly due to the fall between the upstream and the downstream, and at a high cost, Not only had to be equipped, but also had to be checked frequently.

As a related art related to such a fishery device, Korean Patent No. 0516997 discloses rails at both station sections so that a mother ship or a vessel can safely move regardless of a roadway of the fishery. Of course, a technique related to a self-propelled fish-based system using a monorail is disclosed, which enables fish catching and releasing doors installed in a ship to be automatically opened and closed by a motor and a hook.

However, such a device requires a lot of construction costs because, as described above, when installing an airway in a large free fall dam or waterfall, a complex electric system and a control system for long-distance waterways or mechanical operation must be provided. There was a problem such as a constant check by the administrator.

In addition, Korean Patent Laid-Open Publication No. 2007-0020533 discloses that a bucket is installed in both up and down directions of an elevator so that the downstream water is contained in an upward bucket while the elevator rotates due to the weight of the downward bucket containing the upstream water. A technique related to a "hydraulic elevator fish" which can move the fish collected through the guided fishery upstream by allowing it to flow upstream is disclosed.

These devices do not require a separate power plant for the operation of the machine at a small footprint, which saves installation costs and facilitates maintenance, while fish can only be moved if they are forced into the up bucket. Natural fish cannot be moved, so it can't effectively function as a fish.

The present invention has been made to solve the above problems, the object of the present invention is to facilitate the construction and management of the fish by moving the fish by the lifting and lowering operation of the elevator installed in the front of the dam It is to provide a fishery device that can greatly reduce the cost.

And a water supply unit for supplying water to a distribution path disposed at an upper end of a hoistway of the dam, including a water tank, a water tank that always floats on the upstream side of the water, and a pipeline connected to the water tank. .

In addition, the first and second staircase blocks are formed by stacking individual boxes having an open top, and connecting boxes and artificial plants to each of these boxes are configured to induce upward movement of fish. It is done.

In addition, the water tank is provided with a stopper for opening and closing the water by operating by a lever, and at the same time it is characterized in that a pair of sensors for detecting the water level is mounted on the side wall.

In addition, the third step block for inducing the upward movement of the fish is provided in the pipeline constituting the water supply unit.

The adobe block according to the present invention for realizing the above object is formed in a step shape by laminating the individual box body having an open top one by one at each end, and each of the box body is formed with a curved plate and a protrusion formed with projections. The myelin sheath is characterized in that it is configured to induce upward movement of fish.

In addition, the groove is formed on the inner surface of the box body, characterized in that the upper end portion of the front portion is composed of an inclined surface so as to have a flow rate difference.

According to the fishery device and the fish block of the present invention having the features as described above, because the construction is configured to enable the movement of the fry or eel by an elevator that moves up and down along the hoistway formed on the front of the dam, construction and management It is easy to reduce costs.

In addition, the instinct of the fish to go upstream is usually provided by supplying water upstream along the path of the fish at all times and by installing a stepped block having a connection plate, a bending plate, or artificial plants. It is possible to take full advantage of its natural resources and to more effectively use its natural functions, thus protecting fish stocks and increasing aquatic production.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 6 are views for explaining the fishery apparatus according to the present invention, and as shown in these drawings, the upper and lower positions of the upper and lower limits are positioned along the hoistway 11 provided on the downstream front side of the dam 10. An elevator 12 that operates repeatedly and a water supply unit 13 for continuously supplying upstream water into the elevator 12 are provided.

According to the present invention configured as described above, first, when the elevator 12 is stopped at the lower end of the hoistway 11 of the dam 10, ie, downstream, the entrance 19a of the elevator 12 in which various fish are always filled with water. And into the elevator 12 through the first stair block 14A to wait for a predetermined time.

At this time, since the connecting plate 21 and the artificial water plant 22 are bound to the box constituting the first staircase block 14A, the toothed plate, the eel, the snail and the like are connected to the connecting plate 21 and the artificial body. It is possible to perform more naturally and easily through the inlet 19a in the elevator 12 depending on the plants 22.

In the above state, the water continues to flow from the water tank 30 disposed upstream of the dam 10 through the branch path 27a provided in the conduit 31 and the flow passage 27, and thus the water tank 23. As it is introduced into a predetermined amount of water is filled up and the motor 15 is operated by the operation of the sensor 26a for detecting the water level.

As a result, the elevator 12 gradually starts to move upward, and the lever 24 mounted to the water tank 23 is pressed by the protruding rod 11a to open the stopper 25, thereby opening the water tank. Water in 23 gradually flows out toward the second stair block 14B. When the elevator 12 reaches the top position, the motor 15 is stopped by a sensor operation (not shown).

At this time, the upstream side of the water tank through the flow passage 27 by blocking the branch passage 27a by the valve body 29 while the operation 28 installed in the flow passage 27 moves upward. (23) can continue to be supplied, the fish in the elevator (12) flows back along the second stair block (14B) through the outlet (19b) and the water tank along the flow path 27 and pipeline 31 After entering into 30 will be able to move upstream again through the through hole (30a).

Also in this case, like the first step block 14A, the connecting plate 21 and the artificial plants 22 are bound to the box constituting the second step block 14B. Since the staircase block 32 is installed to assist the fish to move upward easily.

Next, as described above, when all the water is released from the water tank 23, the outlet hole is closed by the stopper 25 in the water tank 23 and the sensor for detecting the water level in the water tank 23 ( As the motor 15 is rotated reversely to operate the motor 26b, the elevator 12 descends and returns to its original position. The valve body 29 is opened again by the operation period 28, and the flow path 27 By opening the branch path 27a, the upstream water can be continuously stored in the water tank 23.

While repeatedly performing such a series of operations, various kinds of fish intended to be slaughtered from downstream to upstream can be moved by the elevator 12 installed in the dam 10 without difficulty.

On the other hand, Figures 7 and 8a, 8b is a view for explaining the adobe block according to the present invention, this adobe block can be installed in the elevator in the above-described example, as well as can be applied to a conventional waterway type fish.
