Description

Submergence type fish way}

The present invention relates to a fish that allows fish to move freely through high information in facilities such as dams or high information installed across rivers, and allows fish to climb up and go to the bottom of the estuary. It's about food.

In general, rivers are installed with dams across rivers or with concrete information to store water for agricultural or industrial use, or for power generation. Sluice gates or movable beams are installed to adjust.

Since the fixed beam blocks the river using a concrete structure, the downstream and the upstream of the river are disconnected, which makes it difficult for the fish to move up and down, and thus the habitat environment of the various fish inhabiting the river is increased. There is a problem of change and ecosystem destruction.

In order to solve this problem, one or more fishes are installed in the high information so that the fish can move upstream. However, the existing fishes have a structure in which the fish gradually enters the upstream with a drop or flow rate. If it does not win, the movement of the fish is blocked, and the installation distance of the fish is also increased, and the water temperature of the water flowing through the inclined fish is increased, which hinders the movement of the fish.

In particular, when using a sloped fish is to form a certain slope in order to lower the flow rate, the sloped fish has a problem that the length of the fish is long, the temperature of the water flowing through the upper portion of the fish rises by the sun There is a problem that hinders the movement, there is a problem that catches the fish moving along the island because the fish is exposed, there is a problem that takes a long time to install the fish.

The present invention relates to a fish that allows the fish to move freely in the high information installed in the river, when using the inclined fish takes a long installation period, the length of the problem along with the length of the water flowing through the upper layer of the fish It is to solve the problem of being raised by sunlight and hindering the movement of fish, and to solve the problem of fish movement being exposed to the outside, and the bottom of the fish through the through hole formed in the fish By moving the fish upstream and then moving upstream, the fish can move without being exposed to the surface, while the fish is free to move. You can move without feeling.

In particular, the present invention lowers the flow rate of the river water flowing through the upper side of the esophagus so that the fish can easily move through the esophagus, while forming a decompression tank to reduce the water pressure ejected from the bottom of the esophagus and the through hole penetrated by the fish It is to be moved upstream in the state of moving to the bottom of the fish through the through-hole installed inside the tank.

According to the present invention, the retaining wall is inclined on both sides of one side of the high information installed at a predetermined height across the river, so that water is introduced by the inlet, and the airway is inclined along the retaining wall in the space between the retaining walls. While the center of gravity is located to the rear of the hinge, the fish is rotated by the hydraulic pressure of the dock formed in the space between the bottom of the fish and the retaining wall, the cross section of the upper portion of the fish The water tank is installed in multiple stages, but forms a through-hole penetrating the bottom of the fishery in the decompression tank, which is the inner space of the water tank, and forms a moving passageway in the decompression tank of the tank, which is installed in the multi-stage, and the river water flows in. On the other hand, it forms a overflow groove on the upper side and overflows the river water. The stream water discharged to the upper side flows along the fish road after the pressure is lowered in the decompression tank of the tank, and the fish moves through the moving passageway and the overflow groove formed in the tank frame installed in the fish tank in multiple stages, and then through the low pressure through hole. After moving to the bottom of the fish can be moved upstream through the bottom dock of the fish.

The present invention allows the fish to move on the upper side of the fish inclined to the bottom of the fish through a through hole drilled in the fish without going to the upper side of the fish formed in the tank formed by the fish tank frame installed on the fish After moving, it moves upstream, allowing fish to move effortlessly, while the fish is submerged and moved to the bottom of the fish. The movement is free, and river water is ejected from the bottom of the fish. It is to prevent changes in the water temperature of the stream flowing through the upper side so that the fish do not interfere with the movement of the fish on the upper part of the fish.

In particular, the present invention is lowered by using a decompression tank of a water tank frame installed in multiple stages in the bottom of the esophagus, so that the river water is discharged from the through hole drilled in the bottom of the esophagus, so that the fish can move through the eoe less resistance and through the through hole It is easy to move through the bottom of the fish.

The submersible fish of the present invention is to allow the fish to move upstream by submerging in a dock in the decompression tank of the tank that is installed in multiple stages without going up to the top of the fish,

first. Since the water pressure of the stream water discharged to the through hole through the decompression tank is lowered, the fish can easily dive through the through hole,

second. When the upstream water level is lowered, the upper inlet of the fish must be lowered. In the submersible fishery of the present invention, the fish can move according to the water level being lowered because it can be directly submerged into the dock in the decompression tank of the tank formed in each section of the fishery. ,

third. The fish is difficult to move because the water temperature rises when the fish is exposed to sunlight, but the submerged fish of the present invention penetrates into the dock into which the upstream water that forms the upper part of the stream flows, so that the water temperature in the fish becomes the same as the temperature of the river water so that the fish can move easily. Become,

fourth. The fish is exposed to the outside to go back to the long fish, the submersible fish of the present invention is well protected from the outside because it is submerged into the dock in the middle of the fish without going to the top of the fish,

fifth. Since the submersible fish of the present invention is manufactured and transported in a factory, the construction period is shortened, and is made of stainless steel and is semi-permanent.

The present invention relates to a fishery which is a moving passage of fish that prevents the movement of fish due to a cement structure such as a dam or high information installed across a river, and installs the fish inclined separately from the high information. By lowering the flow rate of the river water flowing through the upper part and allowing the fish to move to the bottom of the fish through the through hole formed in the fish, the fish climbs up to the bottom of the fish without moving to the top of the fish To make it move to.

The fish of the present invention is manufactured in a factory made of stainless steel and assembled in high information, by forming a dock to which the hydraulic pressure is applied between the bottom of the fish and the fish, the slope of the fish is changed by the pressure applied to the dock. At the bottom of the esophagus, a fish tank forms a through hole through which the fish moves from the upper part of the fish to the bottom surface, and the tank is placed in the fish tank in multiple stages so that the pressure of the river water discharged to the through hole is reduced.

The water tank frame installed in multiple stages on the island also forms a water tank that traps the river water flowing through the island, thereby providing a space for fish to swim while resting on the island.

In accordance with the present invention the length and weight and the hydraulic pressure supported by the dock to maintain the balance of the fish by the usual water pressure, during the flood to open the lower side of the fish, in the dry season to close the fish .

In the fishery of the present invention, the tank having a cross-shaped cross section upward is installed in multiple stages so that the river water flowing through the upper side of the fishery flows through the tank formed by several tanks, and formed inside the tank. Through-holes are formed at the bottom of the decompression tank, and moving passageways are formed in front and rear of the decompression tank to allow inflow and outflow of river water, and an overflow groove is formed on the upper side of the tank to overflow the river water. The fish moves upstream through the overflow groove or through the moving passage to the decompression tank and then dive through the through hole.

Here, the diameter of the through hole located on the upper side of the fish is gradually larger than the diameter of the through hole located on the lower side of the fish.

And, if the tank is formed in multiple stages in the fishery, the river flows through the fishery blocked by the tank to form a water tank and flows through the overflow groove, so that the fish can flow and rest in multiple stages. .

The fishery of the present invention is installed to be inclined to the high information, to install the retaining wall having a predetermined width on both sides of one side of the high information inclined, and to the space between the retaining wall inclined to install the fish to be rotated by the hinge in the lower center of gravity The bottom of the fish is introduced into the river water through the inlet, the water pressure is applied to the bottom of the fish in the dock constituting the bottom of the high information and the bottom of the fish.

In other words, the water flowing through the inlet in the high information is filled in the dock to apply a water pressure to the bottom of the esophagus, by adjusting the position of the hinge in consideration of the water pressure of the dock and the length and weight of the esophagus in normal times In the flood, only the lower side of the esophagus is heard, and in the dry season the lower side of the esophagus is closed.

In the present invention, when the average amount of the river flows because the river water is filled in the dock and the water pressure is applied to the fish, the water flows through the inlet or the river water flows through the inlet, or the river water is filled in the dock After that, through the through hole drilled in the bottom of the esophagus will be ejected to the top of the esophagus.

The water flowing through the upper part of the estuary fills the tank of the multistage tank, and flows through the channel's moving passageway or overflows through the overflow groove to lower the flow rate. Since it is ejected into the decompression tank of the water tank frame installed in multiple stages, the pressure is greatly reduced in the decompression tank and then discharged through the moving passage.

Here, the stream water is ejected through the through hole which is drilled in the bottom of the esophagus in the inside of the decompression tank, and the decompression is performed in the decompression tank, so that the fish moves through the overflow groove in the tank of the tank installed in multiple stages, The ejection pressure is moved to the bottom of the esophagus through a through hole where the ejection pressure is suitable for movement, and then upstream.

That is, the water pressure of the stream water discharged through the through hole varies according to the diameter of the through hole and the water pressure of the dock, but since the discharge pressure is lowered in the decompression tank, the fish moves on the upper surface of the fish island and the discharge pressure of the through hole is low. At the point of loss, it moves through the through hole to the bottom of the fish.

Next, during the flood season, the water level rises and the water pressure applied to the bottom of the fish in the dock increases, so the lower side of the fish is opened to clean the foreign matter accumulated in the dock, and in the dry season, the water pressure applied to the water bottom in the dock. Since this lowers, the fish will remain closed.

As described above, the present invention allows the river water to be ejected through the through hole drilled in the bottom of the fish, while the water pressure of the river water sprayed from the upper surface of the fish to the through hole is reduced in the decompression tank to ride on the upper surface of the fish. When the water pressure is equal to or slightly higher than the moving river water, the fish moves through the through hole through which the water is ejected, and it is the instinct of the fish to move to the place where the water flows out.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to the fishery 50 which is installed inclined to the high information 10 which is a concrete structure installed across the river, so that the fishery 50 can be installed to one side of the high information 10 to have a predetermined width. The retaining wall 21 is formed to protrude from both sides, but the retaining wall 21 is inclined so as to be lowered from the upstream to the downstream.

The inner space of the high information 10 installed by the retaining wall 21 has a cross section.

Figure pat00001
The retaining wall 21 is installed at both sides to allow the river water to be blocked by the high information 10 to flow from the inlet 30 to the space between the retaining walls 21.

The fish 50 of the present invention is installed by the hinge 51 so as to be rotatable in the space between the retaining walls 21, and the dock 20 is formed between the fish 50 and the bottom surface of the high information 10. In consideration of the water pressure applied to the bottom of the fisherman 50, and the length and weight of the fisherman 50, the hinge 51 is installed at a position that can be balanced when the river water maintains the average amount.

At this time, even when the inclined fish 50 is fixed in an inclined state, there is no problem in operation, and the inclined fish 50 has a lower side opening and closing around the hinge 51 to allow the fish 50 to be flooded. This is to clean the foreign matter filled in the lower side of the fishery 50 by opening.

Fish 50 of the present invention has a cross section

Figure pat00002
It has a shape, and is manufactured in a factory using stainless steel so as to have a certain length, and then assembled in the field, the construction period is shortened, and the shape of the fish tank frame 60 in the upper surface of the fishery (50) River water installed in multiple stages along the inclination of the fisherman 50 is stored in the water tank 66 formed by the fish tank 60, and the moving passageway 62 of the fish tank 60 is installed. Flow along (63) or overflowing the overflow groove (64).

The water tank frame 60 is a flow passage (62) (63) to let the river water overflow or through the inside of the decompression tank (65) in the upstream groove (64) formed in the state filled with the river water in the water tank (66) By allowing the river water to flow through, lowering the flow rate of the river water flowing through the fish road (50) to allow the fish to move easily.

When the river water is filled in the water tank (60), which is installed in multiple stages in the airway (50), water flows through the moving passage holes (62) and (63) of the water tank (60). There are a lot of fish that can't move on 63).

Therefore, when a water pressure rising from the dock 20 is applied to the decompression tank 65 of the water tank 60, a water wall is formed to block the flow rate of the river water flowing through the decompression tank 60, Slows down the flow rate

That is, if the flow rate and flow rate flowing in the decompression tank 65 formed in the tank 60 of the fish tank 50 is equal to the water pressure rising from the dock 20 or if the water pressure is slightly increased, the flow rate is stagnant or the flow rate is slowed. All.

According to the principle described above, the flow rate of the fish flows through the fish 50 is low, so that the fish can easily move.

As described above, in the pressure reduction tank 65 of the present invention, the pressure of the river water jetted through the dock 20 and the through-hole 61 penetrating inward is reduced in the pressure reduction tank 65, whereby the fish moves through the passageway 62. After moving to the pressure-reducing tank (65) through (63) to the dock 20 through the through hole 61 or to the upper side through the moving passageway (62, 63), the through hole The diameter 61 becomes larger toward the higher side than the lower side of the fisherman 50. As shown to FIG.

The decompression tank 65 of the fishery 50 discharges the water pressure of the stream water discharged through the through hole 61 to the moving passageway 63, and flows through the fishery 50 while the moving passageway 62 flows. The river water that did not flow into (63) flows in the overflow groove (64) while being stored in the tank (60) installed in multiple stages.

The pressure reduction tank 65 lowers the pressure of the river water sprayed into the through hole 61 so that the fish can move to the dock 20 through the through hole 61. Through the upper part of 50), the temperature of the river water flowing through the fishery 50 is prevented from rising.

The through hole 61 of the present invention is larger in diameter toward the upper side than the lower side according to the water head difference according to the inclination of the fish 50, and the large fish is the bottom of the fish 50 through the through hole 61 located at the top. In order to move the fish, in order to achieve the movement of the fish over the overhang groove 64 of the tank 60 in the upper side of the fish (50) or through the decompression tank (65) through the moving passageway (62, 63) This is because the flow rate of the river water in the decompression tank (65) becomes weak because the fish naturally moves to the bottom dock (20) of the fish (50) through the through hole (61).

That is, when the river water is filled in the dock 20, the river water is ejected through the through hole 61 of the fishery 50, but the river water gradually goes to the lower side of the fishery 50 according to the difference in water pressure and the diameter difference of the through hole 61. Is strongly ejected, but the stream water ejected from the through hole 61 is reduced in the decompression tank 65 so that the water flows through the upper portion of the fisheries 50 so that the fish can withstand the water flow. The sphere 61 is present, the fish is moved through the through hole 61, but the movement is made through the through hole 61 of the appropriate size according to the size of the fish.

In the present invention having such a configuration, the waterway 50 installed in the space between the retaining walls 21 formed in the high information 10 so as to be rotatable using the hinge 51 does not flow the river water because the center of gravity is located rearward. If not, the fish 50 will remain inclined.

Fish 50 of the present invention is installed to be movable by the hinge 51, in consideration of the water pressure in the dock 20 and the length and weight of the fish 50 in the dock 20 when the river water flowing through the river maintains the average quantity While the waterway 50 is installed to maintain equilibrium, during flooding, the water pressure in the dock 20 is increased so that the lower side of the waterway 50 is completely opened to be cleaned.

The river water flowing through the inlet 30 fills the bottom dock 20 of the fishery 50 and is ejected to the upper portion of the fishery 50 through the through hole 61 drilled in the fishery 50. The river water jetted at 61 is made of a water wall in the decompression tank 65 of the tank 60 installed in multiple stages so that the flow paths of the moving passages 62 and 63 are lowered.

At this time, the temperature of the river water flowing upward of the fishery 50 is maintained by the sunlight due to the river water is discharged to the through-hole 61 of the present invention to maintain almost the same temperature as the river water, thereby causing no temperature change Fish can go up without feeling rejected.

In particular, the through hole 61 of the present invention becomes larger in diameter from the lower side to the higher side of the fish 50, the fish moved to the decompression tank 65 to the dock 20 through the through hole 61 It is movable. Since the water pressure ejected from the through hole 61 is lower toward the upper portion of the fishery 50, the fish has a water pressure enough to pass through the through hole 61 and the fish is docked at a place having a sufficient diameter. Go to (20).

The fish moved to the dock 20 moves upstream through the inlet port 30, and the fish moved upwardly of the fish tank 50 also moves upstream through the inlet port 30.

Therefore, in the present invention, the fish does not move to the upper portion of the fishery 50, but moves to some extent, but moves to the bottom of the fishery 50 through the through hole 61, and then moves upstream. It is not exposed to the upper surface of the) is to move upstream through the dive in the dock (20).

Meanwhile, in the present invention, since the water pressure of the dock 20 is large in the flood season, the lower side of the fisherman 50 is opened, so that the benthos can move along the bottom of the fisherman 50, as well as the residue accumulated in the dock 20. It can be discharged and cleaned.

As described above, according to the present invention, the fish is moved through the dock 20 formed on the bottom surface of the fish tank 50 by using the through hole 61 drilled in the fish tank 50. It can be moved upstream without going up to the end, as well as lowering the flow rate of the river water flowing through the esophagus 50, the fish can easily move, the river water flows a large amount to the upper side of the esophagus 50, the river water flowing through the upper portion of the esophagus 50 The temperature of the fish does not rise, and the fish can move without being exposed.

And, since the fish 50 of the present invention is manufactured and installed outside, it is possible to shorten the construction period as well as to play the role of the fish with a short length.
