In order to effectively use the energy of the released water, a valve-type power generation turbine may be installed. However, it is necessary to reliably discharge the cooling water even if peripheral devices such as the water turbine, the gate, and the water tank fail so as not to hinder the operation of the nuclear power plant or the thermal power plant. FIG. 3 (A) is a plan view of a conventional discharge and maintenance device for a water turbine for power generation,
(B) is the front view. In FIG. 3, the water discharged from the cooling water discharge pipe 1 of a nuclear power plant or a thermal power plant is temporarily stored in a water storage tank 2, and a valve type water turbine 5 is installed downstream of the water storage tank 2. The waterway is divided by gate 6. A valve-type water turbine 5, which is a power generation turbine, includes a guide vane 7 and a runner 8. A weir 3 is provided on the side surface of the water tank 2,
A water discharge channel 4 is provided on the side surface of the cough 3. The height from the center of the cooling water discharge pipe 1 to the water surface of the water storage tank is H 1 , and the height from the center of the cooling water discharge pipe 1 to the upper end of the weir is H 2 .
When the water level of the water tank exceeds the height H 2 of the upper end of the weir, the water of the water tank is discharged from the water discharge channel 4 over the weir. for that reason,
Even when the gate 6 is closed and the power generating turbine 5 is stopped or a peripheral device fails, the cooling water can be discharged from the discharge channel 4.

大きくなるという問題があった。In the conventional maintenance and discharge device for a water turbine for power generation, since the weir 3 is a square weir, the amount of water discharged from the weir 3 is determined as follows. Discharge amount Q = K × B × H × (2gH) 0.5 where K is the flow coefficient of the weir, B is the width of the weir, H = H 1 −
H 2 . In the case of a square weir, the flow coefficient K is usually 0.45 or less. Considering the case where a valve turbine is installed in an existing nuclear power plant or thermal power plant, the capacity of the cooling water pump sent from the cooling water discharge pipe 1 to the water tank 2 is fixed, and the capacity up to the water surface of the water tank is fixed. The height H 1 is naturally determined within the range determined by the capacity of the pump. Height H to the top of cough
2 in order to increase the power generation amount by increasing the head drop during water turbine operation, it is desirable that as high as possible. Therefore, H 2 is usually set to 2 m or less. Conventionally, there has been a problem that the width B of the weir becomes large in order to increase the amount of water discharged, so that the capacity of the water storage tank 2 also becomes large and the maintenance and discharge device of the power generation turbine becomes large.

比例する。Further, in the present invention, the power generation turbine is driven by the cooling water discharged from the nuclear power plant or the thermal power plant through the cooling water discharge pipe to generate power, and the cooling water is discharged to maintain the discharge. In the maintenance and discharge device for water turbines, a water pipe that branches from the cooling water discharge pipe and conducts water to the turbine for power generation and a water discharge pipe that discharges water to the discharge canal are installed up to a position higher than the center of the water pipe.

Water is discharged and then flows through the discharge channel. At that time, the amount of water discharged from the discharge pipe is proportional to the cross-sectional area of the discharge pipe and the square root of the head from the top of the discharge pipe to the opening.

In FIG. 1, the same parts as those in FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted. 1 (A), (B)
In the above, a water guide pipe 9 branched from the cooling water discharge pipe 1 and conducting water to the turbine for power generation and a water discharge pipe 10 discharging to the water discharge passage 4 are provided. The water discharge pipe 10 rises to a position H 4 higher than the center of the water conduit 9 and further bends downward to discharge water to the water discharge channel 4 at a position H 3 higher than the center of the water conduit 9. At that time, H 4 is the same as H 1 in FIG. 3, and H 3 is the same as H 2 in FIG. If H 5 = H 4 −H 3 , the water discharge amount Q = A ×
(2 gH 5 ) becomes 0.5 . A is the tube area. The flow coefficient of the water discharge pipe 10 is about 1 to improve the water discharge efficiency. To increase the water discharge amount, the diameter of the water discharge pipe 10 may be increased or a plurality of water discharge pipes may be provided. When the turbine is stopped, the gate 6 is closed, and all the cooling water supplied from the cooling water discharge pipe 1 flows from the water discharge pipe 10 to the water discharge passage 4. When the turbine starts and the flow rate of the turbine increases, the flow rate of the discharge pipe 10 decreases,
When the pressure of the cooling water discharge pipe 1 decreases to the pressure of the water head H 2 , the water passing through the water discharge pipe 10 disappears, and all the cooling water flows into the turbine side. For this reason, it is not necessary to use a wide water tank as in the conventional case, and the water discharge facility can be made small.

In FIGS. 2A and 2B, the same parts as those in FIG. 3 are designated by the same reference numerals, and the description thereof will be omitted. Figure 2
In the above, a water guide pipe 9 that branches from the cooling water discharge pipe 1 and guides the water to the power generation turbine and a water discharge pipe 10 that discharges the water to the water discharge passage 4 are provided. The discharge pipe 10 is located at a position H higher than the center of the water pipe 9.
Start up to 4 , bend further downward and discharge water to the discharge channel 4 at a position lower than the center of the water pipe. At that time, H 4 is the same as H 1 in FIG. 3, and H 6 is larger than H 4 . When the water head in the water discharge pipe 10 reaches near H 4 Water discharge pipe 1
The inside of 0 is filled with water and discharged. At this time, water discharge Q = A
× (2gH 6 ) 0.5 . A is the tube area. The flow coefficient of the water discharge pipe 10 is about 1 to improve the water discharge efficiency. H
Since 6 is larger than H 5 in FIG. 1 (B), the flow velocity in the water discharge pipe 10 is increased. However, during operation of the water turbine, the valve 11 is provided in order to prevent the water from flowing from the discharge pipe 10 due to the siphon effect and reducing the water turbine output even if the pressure of the water turbine drops to the required head H 3 . The valve 11 is either a vacuum break valve, a manual valve, or an electric valve that operates when the pressure of the cooling water discharge pipe 1 drops to H 3 . The pressure of the cooling water discharge pipe 1 is H
When 3 is exceeded, valve 11 closes again. The maintenance and discharge device of FIG. 2 also eliminates the need for a water tank having a large width as in the conventional case, and the water discharge facility can be downsized.
