A water level adjusting pipe 6 for adjusting the water level in the storage container 1a when the storage is completed and the wall surface of the dam 5 is raised is installed via the swivel pipe 4b similar to the above. In addition, on the bottom surface of the storage container 1a, when the storage container 1a is stored in the water tank 7 (see FIG. 1) as a previous step of storing the upstream fish in the storage container 1a,
A check valve 8 is provided to keep the water level inside and the water level inside the storage container 1a together.

Further, as shown in FIG. 1, the elevating and moving means 1b is a trolley 9 for suspending the storage container 1a described above and a guide for guiding the trolley 9 upward along the downstream wall surface of the dam 5. It is composed of a rail 10 and a winch 11 arranged at the top end of the dam 5 for moving the carriage 9 up and down along the guide rail 10.

Reference numeral 12 is a bank below the top road 5a of the dam 5, for example, in order to transfer the upstream fish discharged together with water from the ascending / descending device 1 for climbing to the upstream wall surface side of the dam 5. This is a discharge channel that is provided through the body.
The inlet 12a of 2 is located at the top of the dam, and the outlet 1 is
2b is provided near the full water level on the upstream side of the dam.
The reason is that even if a gate is not installed at the inlet 12a, there is no fear that the water in the reservoir will flow out through the discharge waterway 12 to the downstream even at the water level at the time of flood.

In the embodiment shown in FIG. 4, the discharge water channel 1
Although the exposed part in 2 is a conduit, it may be an open channel with the sidewall of the exposed part aligned with the top end of the dam 5 as shown in FIG. 5, or the top end road of the dam 5 as shown in FIG. 5
It goes without saying that the discharge water channel 12 may be installed outside the transportation limit of a.

Numeral 13 is an elevating and lowering device for releasing fish which receives the upstream fish flowing along with water in the discharge channel 12 and descends the upstream wall of the dam 5 to the reservoir, and then releases the upstream fish into the reservoir. There is a fish storage container 13a and an elevating and moving means 13b for the storage container 13a. The storage container 13a has a screen 1 on both sides of the upper part thereof for allowing spillage to flow to the reservoir when receiving the run-up fish flowing with water into the storage container 13a.
4 are installed.

Further, as shown in FIG. 7, the elevating and moving means 13b is a trolley 15 for installing the above-mentioned storage container 13a.
And a guide rail 16 for guiding the carriage 15 downward along the upstream wall surface of the dam 5, and a winch 17 arranged at the top end of the dam 5 for moving the carriage 15 up and down along the guide rail 16. It is composed of. The storage container 13a is attached to the trolley 15 via a rotary hinge 15a provided on the lower surface of the storage container 13a on the side opposite to the dam, and the storage container 13a is attached to the side surface on the dam side when the storage container 13a is submerged in a reservoir. Is provided with a float 18 for rotating about the rotary hinge 15a as a fulcrum to reliably escape the run-up fish in the storage container 13a.
Needless to say, the float 18 is not always essential.

Further, at a position above the storage container 13a of the carriage 15, when the storage container 13a guided by the guide rail 16 and lowered is submerged in the reservoir, it can be stopped at a predetermined position in the water. The float 19 is installed. In addition, in the present embodiment, the looseness detecting device 2 for the wire rope 17a is provided at one end of the wire rope 17a of the winch 17.
0 is attached, and when the storage container 13a is submerged in the reservoir, it is stopped at a predetermined position in water by the action of the float 19.

It is configured to stop the lowering of the.

The carriages 9 and 15 are guided by the upper guide rollers 21, the lower guide rollers 22 and the side rollers 23 to the guide rails 10 and 16, respectively, as shown in FIGS. 8 and 9. Has become.

The fish transporting equipment of the present invention is constructed as described above. Next, the operation procedure of this transporting equipment will be described with reference to FIGS.
4 will be described. First, the winch 11 is wound down and the carriage 9 is lowered along the guide rail 10 to store the storage container 1a in the water tank 7 (FIG. 11 (a)). Then, the check valve 8 opens due to the difference in water pressure between the inside and outside of the storage container 1a, and the water in the water tank 7 is poured into the storage container 1a [Fig.
(B)]. Then, when the water levels inside and outside the storage container 1a are combined and the check valve 8 is closed [Fig. 11 (c)], the run-up fish is poured together with water from the slope 24 [Fig. 12 (a)]. At this time, the spilled water overflows from the screen 2 of the storage container 1a and flows out into the spill tank [FIG. 12 (b)], and the run-up fish is stored in the storage container 1a [FIG. 12 (c)].

When the storage of the upstream fish is completed, the winch 11
Is wound up to raise the dolly 9 along the guide rail 10 to separate the storage container 1a from the water tank 7. At this time, the water level in the storage container 1a becomes a predetermined water level as a result of the action of the water level adjusting pipe 6 to drain the residual water [FIG. 13 (a)]. After reaching a predetermined water level, the swivel pipe 4b is rotated to erect the water level adjusting pipe 6. As a result, due to the shaking of the storage container 1a during the upward movement of the trolley 9, the storage container 1a
The water inside will not overflow [Fig. 13 (b)].

When the trolley 9 reaches the vicinity of the upper limit by winding the winch 11, the stopper 25 provided at a predetermined position abuts the discharge pipe 3, the swivel pipe 4a rotates and the discharge pipe 3 is laid down and stowed. The run-up fish in the container 1a is discharged into the discharge channel 12 together with water [FIG. 13 (c)]. At this time, water drawn from the reservoir by a pump, for example, may be flowed together so that only the upstream fish is not left in the discharge channel 12.

The run-up fish released into the discharge water channel 12 flows into the storage container 13a waiting at a predetermined position together with water. At this time, the spillage is the screen 1 of the storage container 13a.
Since it overflows from 4, only a certain amount of water and runaway fish are stored in the container 1.
It will be stored in 3a [FIG. 14 (a)]. When the storage of the run-up fish is completed, the winch 17 is lowered and the cart 15 is lowered along the guide rail 16 [Fig.
(B)]. When the truck 15 descends below the surface of the reservoir, the buoyancy of the float 19 causes the truck 15 and the storage container 13a to stop at a predetermined position in the water. By this stop,
The wire rope 17a is loosened, and the looseness detection device 20 detects this, and the lowering of the winch 17 is stopped. Further, when the storage container 13a stops at a predetermined position in water, the buoyancy of the float 18 causes the storage container 13a to rotate, and the runaway fish will be surprised and reliably escape to the reservoir [Fig. 14 (c)].

[0019]

As described above, according to the fish transporting facility of the present invention, since the elevator is not required, not only the construction cost but also the maintenance cost is low, and the runaway fish are released from the storage. Since a series of operations up to and including can be performed automatically, labor saving can be achieved and future unmanned operation can be supported, and further, it does not hinder the traffic on the dam top road, and even if the water level in the reservoir changes It has the effect that it can be released safely.

In the embodiment shown in FIGS. 1 to 14, the winch 11 is arranged at the top end of the dam 5 as the ascending / descending means 1b of the ascending / descending device 1; however, as shown in FIG. Needless to say, the rack 26 may be laid along the guide rail 10 and the carriage 9 may be provided with a motor 27 and a pinion 28 that meshes with the rack 26. When the winch 11 is used, as shown in FIG.
From the viewpoint of landscape, the wire rope 11a can be made to follow the bank by the rope guide 29, as shown in FIG. Further, as shown in FIG. 17, it is possible to dispose the winch 11 below the dam 5 by providing a deflection pulley 30 at the top end of the dam 5.

Needless to say, the fish transportation equipment of the present invention can be applied not only to the arch dam shown in FIG. 1 but also to a gravity dam shown in FIG.
