Description

Fish operated by a hydraulic pressure automatically

The present invention belongs to the technical field that ensures the smooth movement of the fish at all times regardless of the water level change by automatically maintaining the appropriate height according to the water level change while the fish is automatically operated by the water pressure.

In general, in rivers, various types of cross-sections are provided to cross the banks and banks of rivers in order to store water and use them as agricultural or industrial waters. Among the cross-sections, the most common is a river beam which is poured with concrete. River streams function to store water so that the water level is always within a certain range, and a hydrologic gate is formed to control the water level during flooding or drought.

However, when river streams are formed of concrete, the downstream and upstream streams of the streams are disconnected, making it difficult for the fish to climb up and down the streams, thus changing the habitat environment of the various fishes in the rivers.

In addition, as the river stream is formed, the fish revolving for spawning cannot move backwards and upstream, and in particular, small fish cannot move steep slopes, resulting in the destruction of the fish ecosystem.

In order to solve such a problem, a predetermined portion of the river can be formed in a wider (about 6M) of a lower height than the upper end of the river can form a fishery that can move or the fish can go upstream on one side of the river Form a step-like etho that makes it possible.

However, the former recessed fish can provide the fish's movement path by passing water through the fish, even when the water level is lower than the river's full water level. This is caused.

In addition, the latter stepped fish can reduce the flow rate, while forming a stepped jaw between upstream and downstream, thus lacking a moving passage for fish to go upstream, which is practically inadequate for fish to move upstream. to be.

In addition, both fishes have a serious problem that the water cannot flow through river streams at low water level, which is common to the water level.

Therefore, the optimal condition for the fish to move smoothly upstream is to reduce the flow rate of the water flowing along the estuary, and in particular, to provide the conditions for the water to flow smoothly along the esophagus, even in the dry season. The situation is not equipped with a fish.

The present invention is to actively solve all the problems inherent to the fishery according to the prior art, and automatically adjusts the inclination and height of the esophagus to suit the water level while automatically buoying or sinking in conjunction with the water level change The problem of the invention is that the water flows smoothly through the air at all times regardless of water level change.

The present invention installs an airway guide communicating with the upstream and downstream between a pair of sluice gates spaced apart as a means for solving the above problems, and one side of the esophagus freely coupled to the bottom surface of the airway guide while the other side is the bottom It is connected to the surface and the folding front plate to form a pressure chamber that is isolated from the outside to the lower side of the esophagus, and the pressure chamber is installed so that the upstream side can pass through the pressure water pipe for supplying pressurized water upstream, On the other side, the technology to install the drainage pipe for draining the water in the pressure chamber to the outside is devised.

According to the present invention, while the upstream water is supplied to the pressure chamber through the pressure water pipe, the water level is automatically lowered by interlocking with the water level while automatically raising or lowering the fish according to the water level change. Even during the dry season, the water flows smoothly and provides the fish's movement path at all times to provide the effect of preserving and restoring the natural ecosystem.

It will be described a preferred embodiment for implementing the solution of the problem to be solved by the present invention in more detail.

Looking at the overall technical configuration according to the preferred embodiment of the present invention based on the accompanying drawings, a pair of sluice gates spaced apart on both sides; An airway guide 20 installed between the water gate 10 so as to be able to flow upstream and downstream; One side is rotatably coupled to the downstream bottom surface 21 of the fish guide 20, the other side is rotatably coupled to the upper end of the folding front plate 32 installed on the upstream side bottom surface 21 Wow; A pressure chamber 40 formed to be isolated from the outside between the fish vessel 30 and the bottom surface 21; A pressure water pipe (50) connected to the pressure chamber (40) so that water flows between the pressure chamber (40) and the upstream side, and pressurizes upstream water to supply the pressure chamber (40); It can be seen that the water passage between the pressure chamber 40 and the downstream side of the water is installed in the organic coupling configuration of the drain pipe 60 to drain the water of the pressure chamber 40 to the outside.

Hereinafter, the present invention made of the above-described schematic configuration will be described more easily.

According to the present invention, a pair of sluice gates spaced to both sides is installed across the river, and between the sluices 10 stably accommodates the fish 30 and at the same time, the fish 30 smoothly supports or goes away. An airway guide 20 for guiding the up and down movement to be seated is installed.

The fish guide 20 is formed in the form of a general channel having an open top and sidewalls 22 formed on both sides of the bottom surface 21, and on the outer surface of the sidewall 22 to prevent leakage of water installed at the water gate 10, respectively. The stand 11 is in close contact with each other to prevent leakage, and both sides are opened to allow water to flow upward and downstream.

The fish 30 accommodated in the Singapore guide 20 is pivotally rotated up and down from the hinge shaft 31 by one side rotatably coupled to the downstream bottom surface 21 via the hinge shaft 31. It is operable, and the other side is coupled to the upstream side bottom surface 21 by the hinge shaft 31 and the upper end of the foldable front plate 32 which is also rotatably coupled via the hinge shaft 31.

Therefore, the bottom 21, the fish 30, and the folding front plate 32 of the fish guide 20 form a triangular structure and are isolated from the outside to form a space between the fish 30 and the bottom 21. The pressure chamber 40 is formed to fill the pressure water, and according to the strength of the water pressure by the pressure water supplied to the pressure chamber 40, the fish can 30 can be automatically raised or lowered.

That is, the fish vessel 30 is gradually buoyed as the water pressure increases and the water pressure of the water supplied to the pressure chamber 40 becomes stronger, and when the water pressure decreases, the water pressure of the water supplied to the pressure chamber 40 decreases. In particular, it sinks more smoothly due to its own weight.

At this time, the fish 30 may support a sufficient amount as the hydraulic pressure acts, but a plurality of floats 34 are integrally installed on the bottom surface so that the fish can be more smoothly supported. The bottom surface 21 corresponds to the bulge 34 in consideration of the occurrence of a failure in reaching the position close to the bottom surface 21 while touching the bottom surface 21 when sinking. Since the recessed groove 35 is formed at a position, even though the water level is very low as shown in FIG. 4, the water can always flow smoothly downstream through the fish vessel 30.

In addition, the fish 30 is subjected to water pressure or bends due to its own weight due to the nature of being manufactured in a very long length in order to maintain a gentle inclination that can smoothly flow fish, as well as the processability is reduced.

Accordingly, the present invention constructs a long length of fish 30 which is completed by continuously connecting and assembling a plurality of prefabricated fish plates 36 in consideration of such a point, and the prefabricated fish plate 36 as a technical configuration for this. ) Are continuously connected to each other, but the bottom of the connecting portion between the prefabricated fish plate 36 is abutted so that the reinforcing plate 37 overlaps both sides as shown in Figure 5, the reinforcing plate 37 and the prefabricated fish plate 36 is riveted It is possible to keep the solid assembly state integrated through the 38.

As a result, it is easy to manufacture and provides the convenience of maintenance and repair to replace, repair only a corresponding part only in case of partial breakage, and also to suppress deformation such as bending.

On the other hand, the pressure water pipe 50 for pressurizing and supplying the water upstream side to the pressure chamber 40 is installed more than both sides of the pressure chamber 40 and the upstream side through the water passage 30, Potential energy is generated by the altitude difference between the pressure chamber 40 located on the upstream side and the water chamber on the upstream side, and the water flowing along the pressure water pipe 50 gradually increases as the potential energy increases toward the downstream side. It is supplied to the pressure chamber 40 while being stronger, the hydraulic pressure strength of the pressure water supplied to the pressure chamber 40 is automatically changed according to the change of the water level.

Therefore, the waterway 30 is elevated in height and inclination while raising the upper portion like a tube by the water pressure of the water supplied to the pressure chamber 40, and in this case, since the water level is high, there is no need for the fish to move up and down. There is no obstacle, when the water level is lowered during the dry season, while the strength of the water pressure decreases, as shown in FIG. Edo is also possible smoothly.

At this time, the fish 30 is supported by the stopper 15 protruding from the inner surface of both side walls 22 of the fish guide 20 so as to prevent damage due to excessive support in the process of supporting the fish. You can limit it.

In addition, the drainage pipe 60 is installed between the pressure chamber 40 and the downstream side under water so that the water supply to the pressure chamber 40 is excessively drained through the drainage pipe 60 when the water pressure supplied to the pressure chamber 40 is excessively installed. In addition, the drain pipe 60 may be additionally installed in the drain pipe 60 to artificially turn ON / OFF the drainage pipe or to adjust the drainage amount. In particular, when the valve is completely opened, the foreign matter accumulated in the pressure chamber 40 is externally discharged. It provides the effect of draining.

In addition, the present invention is formed in the upper surface of the fishery 30 as shown in Figure 6 by going to the center of the multi-stage fishing 70 is gradually formed deeper, so that even if the water level is lower than the upper surface of the fishery 30 is multi-stage fishing Water flows through 70 to provide a special effect to provide a path of movement of the fish.

The present invention does not use a separate power source, using the water pressure generated by the potential energy according to the altitude difference between the flow upstream, downstream only automatically adjusts the fish 30 to the appropriate height and gradient according to the water level change at all times It can be seen that the core technology is to provide the fish with a sufficient route of movement.
