Description

Fish apparatus for a water reservoir in river

The present invention relates to a fishery device for forming fish in the underwater beam of the river, more specifically, the height is automatically adjusted according to the height of the water can be easily moved upstream or downstream to protect the fish ecosystem of the river The present invention relates to an underwater fishing system for a river.

In general, rivers install various types of cross-section structures that cross river banks and banks in order to store water and use it for agricultural or industrial water.

The most common among the cross-sectional structure is concrete underwater beams, and the underwater beams function to store water so that the level of water stored is always within a certain range, and a sluice is formed to control the water level during a flood or drought. do.

However, the formation of underwater beams with concrete results in the disconnection of the downstream and upstream of the stream, making it difficult for fish families to climb up and down the stream, thus changing the habitat environment of the various species living in the stream. do.

In particular, as the underwater beams are formed, the fish returning for spawning cannot be moved backwards and downstream, and in particular, small fish cannot move steeply, resulting in the destruction of the fish ecosystem.

Due to the above drawback, in recent years, at least one or more waterways are formed in the underwater beams in the process of forming the underwater beams and used as fish that can move.

However, when the depth of the channel is higher than the water level as the height of the channel cannot be adjusted, the channel plays a sufficient role as an esophagus, but when the depth of the channel is low, the water cannot pass through the channel. There is a problem that it is difficult to climb up and down the various kinds of fish streams because of the loss of function.

The present invention has been devised to solve the above-described problems, the height of the fish is automatically adjusted according to the height of the water stored in the underwater beam of the river so that the fish can easily move upstream or downstream. It is an object of the present invention to provide an underwater fishing apparatus.

It can be achieved by providing an underwater fishing device for rivers, characterized in that the screen net is formed fixed to the rear side of both sides of the waterway.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings, which are presented to assist in understanding the present invention, but the present invention is not limited thereto.

1 is an exploded perspective view of the underwater fishing apparatus according to an embodiment of the present invention, Figure 2 is a combined cross-sectional view of the underwater fishing apparatus shown in Figure 1, the underwater fishing apparatus according to the present invention as shown An underwater beam 10 for storing water; A channel 20 formed in the underwater beam 10; Guide grooves 21 formed on both side wall surfaces of the channel 20; An fish forming portion 30 inserted into the guide groove 21; And a screen net 40 fixed to both rear wall surfaces of the channel 20.

The underwater beam 10 is generally installed in a river to store water, at least one channel 20 is formed, the width and depth of the channel 20 can be appropriately adjusted as necessary.

Guide grooves 21 are formed in both side wall surfaces of the channel 20 formed as described above, and the fishery forming portion 30 is inserted into the guide grooves 21.

In this case, the fish forming unit 30 includes an fish block 31 having a plurality of fish 311 formed therein; A buoyancy body (32) formed at the top to enable height adjustment of the adobe block (31); And a rubber tube 33 in which an entrance hole 331 is formed so as to allow the entrance and exit of water in response to the height change of the adobe block 31.

The fish block 31 is formed with a plurality of fish 311 through which fish can pass. According to the present invention, the fish 311 has the height of the water surface so that water stored in the underwater beam 10 can always pass. It is formed at the same position or below the surface of the water. The working relationship will be described below.

A portion of the water stored in the underwater beam 10 is discharged downstream through the fish 311 formed in the fish block 31, in which the fish moves upstream or downstream through the fish 311. The adobe block 31 may be formed using a plastic product such as a PVC injection molded product.

The buoyancy body 32 is formed on the top of the adobe block 31 so that the height of the adobe block 31 can be changed according to the height of the water level stored in the underwater beam 10. The buoyancy body 32 has a height of the water level. In accordance with the movement up and down, corresponding to the height change of the buoyancy body 32, the adobe block 31 formed on the lower end of the buoyancy body 32 is also changed in position.

As a result, the position change of the fish block 31 according to the height of the water level means a change in the position of the fish 311, and thus, the position of the fish 311 is always formed at the same position as the height of the water surface or is formed below. .

The buoyancy body 32 can be easily formed on the upper block 31 by applying a conventional method such as adhesive or ring connection (not shown in the figure), the buoyancy body 32 is made of a material such as styrofoam Applicable

A rubber tube 33 is formed at the bottom of the fish forming portion 30. The rubber tube 33 is automatically changed in height when the height of the fish block 31 is changed by the buoyancy body 32. Will support the block 31.

That is, the rubber tube 33 has an access hole 331 is formed so that the water can come in and out in response to the height change of the adobe block 31, when the buoyancy body 32 is raised to the rubber tube 33 Water is introduced through the ball 331 and the height is increased, and when the buoyancy body 32 is lowered, the water is discharged to the outside of the rubber tube 33 through the entrance hole 331 and the height is reduced. Therefore, the height of the rubber tube 33 is automatically changed in response to the height of the fish block 31 to support the fish block 31.

At this time, the rubber tube 33 may be used as a tube that is changed in height by folding or unfolding as the water enters, as shown, but if necessary, there is no soft wrinkles that the volume is increased by increasing the volume as the water enters and exits. Tubes can also be used.

In the fish forming portion 30 having such a configuration, it is preferable that the rubber tube 33 further includes fixing means that can be fixed to the bottom surface of the water channel 20, which is formed by the fish forming portion 30. (20) This is to prevent the departure from the outside.

The fixing means may be applied in various ways, for example, by fixing the bottom of the rubber tube 33 and the bottom surface of the waterway 20 by a connecting ring (not shown), or as shown The lower end of the rubber tube 33 may be fixed to the bottom surface of the waterway 20 by inserting a weight body 332 such as a lead weight into the rubber tube 33.

According to the present invention, the screen net 40 is fixedly formed at both rear wall surfaces of the waterway 20, and the screen net 40 filters the rubbish and various foreign matters that flow down the river and thereby the rubber tube 33 To prevent damage.

The screen net 40 can be fixed to the rear wall of both sides of the waterway 20 through the bolt 41 is coupled, the very important thing when installing the screen net 40 is to secure a space for the fish can move. The hole of the screen net 40 to form a somewhat larger size to allow the fish to move freely, or when installing the screen net 40 may secure a passage for the fish to move to the bottom.

3A and 3B are views showing the working relationship of the fishery apparatus shown in FIG. 1, as shown in FIG. This rises, the rubber tube 33 for supporting the fish block 31 also rises as the water flows into the entrance hole (). At this time, the water stored in the underwater beam is discharged to the outside through the fish 311 formed in the fish block 31, and in this process, the fish is easily moved upstream or downstream through the fish 311 (see FIG. 3A). ).

In this case, when the water level is lowered, the buoyancy body 32 and the fish block 31 are lowered, and in this process, the rubber tube 33 supporting the fish block 31 is also discharged and the height is lowered. . As a result, the fish block 31 is lowered below the water level so that the fish 311 is formed below the height of the water surface. Therefore, even after the water level is lowered, water is discharged to the outside of the underwater beam through the fish 311, and in this process, the fish easily moves upstream or downstream through the fish 311 (FIG. 3B).

FIG. 4 is an exploded perspective view of the underwater fishing apparatus according to another embodiment of the present invention. As shown, the upper plate 50 in which the plurality of guideways 51 corresponding to the fish 311 is formed is the fish block 31. Is coupled to, the end of the lower plate 60 hinged to the upper plate 50 is fixed to the bottom surface (R) of the underwater beam or river. Such a configuration is preferably formed when the height of the underwater beams 10 is high and the fish cannot easily move upstream or downstream through the fish tract 311.

At this time, in the present invention, the induction path 51 of the upper plate 50 is coupled to the upper block 50 so as to correspond to the positional change of the fish 311, the upper plate 50 is coupled to The lower plate 60 was hinged, but the end of the lower plate 60 was fixed to the bottom surface (R).

The upper plate 50 and the adobe block 31 and the lower plate 60 and the bottom surface (R) can be easily coupled by a conventional connecting method as shown, the lower plate 60 and the upper plate 50 It can be formed by applying plastic products.

5A and 5B are diagrams illustrating an operation relationship of the underwater fishing apparatus shown in FIG. 4. As illustrated, the top plate 50 is coupled to the fish block 31, and the top plate 50 has a bottom end. The bottom plate 60 fixed to the surface (R) is connected by a hinge coupling.

At this time, when the water level is low, the lower plate 60 is in close contact with the bottom surface (R), the upper plate 50 is to be coupled to correspond to the fish 311 of the fish block 31, through the fish 311 The discharged water is discharged downstream of the river along the induction furnace 51 (see Fig. 5a).

In this process, the downstream fish flows up the fishery 311 along the induction road and moves upstream. On the contrary, the upstream fish moves downstream along the induction road through the fishery 311.

On the contrary, when the water level rises, the adobe block 31 moves upward, and at the same time, the upper plate 50 is moved upward, and the upper plate 50 and the lower plate 60 form a straight line. At this time, the water discharged through the fish 311 of the fish block 31 is discharged to the downstream of the stream along the induction path formed in the upper plate 50 and the lower plate 60 (see FIG. 5B). In this process, the fish can easily move upstream or downstream of the stream.

As described above, the present invention provides a useful effect of providing an underwater fishing system for a river, which allows the fish to move easily upstream or downstream by automatically adjusting the height of the fish according to the height of the water stored in the underwater beam of the river. There is.
