とを特徴とする。Further, in the water intake method for a water wheel according to the present invention, a siphon portion is formed when the penstock for guiding water intake to the water wheel is disposed along the weir, and the siphon portion is branched from the siphon portion, and a first valve is provided on the way. It has a first conduit and a second conduit having a second valve and a third valve and bypassing the siphon section. A tank is provided at a junction of the first conduit and the second conduit. In order to guide water intake to a water turbine in a water turbine water intake device which is connected to a penstock between the second valve and the third valve, connects the tank to the downstream side of the water turbine, and arranges a third conduit having a fourth valve. The guide vane and the fourth valve at the inlet of the turbine are closed, and the first valve, the second valve, the third valve, and the fifth valve provided in the siphon section, which communicate with the atmosphere, are opened to take water from the penstock and the penstock. Led to the tank through , Then the first valve, the second valve,
At the same time as closing the third and fifth valves, the fourth valve is opened to drain the water in the tank. After the tank is vacant, the fourth valve is closed, and then the first valve is opened to fill the tank. After the water is filled, the first valve is closed, the guide vane is opened, and water is introduced to the turbine through the penstock.

動するのでサイホン切れはなくなる。(Operation) In the above configuration, in guiding the water from the water intake unit to the water turbine, first, the tank is filled with water via a penstock and a penstock, and then the filled water is drawn out to make the tank empty. In such a state, the tank has a slightly lower pressure than the siphon section.
When the negative pressure of the tank is available, the water from the siphon section is guided to the tank and filled. At this time, the siphon section is guided by water, so that the siphon is not cut off.

The intake dam 1 forms an intake part A. The penstock 3 attached to the intake section A is arranged along the intake weir 1 to form a siphon section B, and is connected to the water wheel 4 from the siphon section B via the guide vane 10.

側まで延ばしてタンク充水後の排水に供している。The siphon section B includes a fifth valve 14 communicating with the atmosphere and a first conduit 12a including the first valve 12. The first conduit 12a bypasses the siphon section B,
It is connected to the tank 9 together with the second conduit 5 having the second valve 6 and the third valve 11. The tank 9 is provided with a third conduit 8 having a fourth valve 13, and the third conduit 8 is extended to the downstream side of the water wheel 4 for drainage after filling the tank.

こうしてタンク９が空室になると、すべてのバルブを閉
口し、このときタンク９は若干の負圧になる。In guiding water from the water intake section to the turbine, first, the guide vane 10 and the fourth valve 13 are closed, and the first valve 12 and the second valve 12 are closed.
The valve 6, the third valve 11, and the fifth valve 14 are opened. When each valve is opened, the water flow from the water intake section A is the first
It is collected in the tank 9 via the conduit 12a and the second conduit 5. When the tank 9 is filled with water, the guide vane 10, the first valve 12, the second valve 6, the third valve 11, and the fifth valve 14, among the valves, are closed, and the fourth valve 13 is opened.
The water in the tank 9 is drawn out and drained to the downstream side of the water wheel 10.
When the tank 9 becomes vacant in this way, all the valves are closed, and at this time, the tank 9 has a slight negative pressure.

ベーン10を開口すれば、サイホン部Ｂの導水は間断なく
水車４に流れる。After the negative pressure in the tank 9, the first valve 12 is opened, and the water flow from the siphon section B is guided to the tank 9 by the siphon action. During this time, the water flow also flows through the siphon section B. If the first valve 12 is closed and the guide vane 10 is opened after the passage of the water flow through the siphon section B, the water flow through the siphon section B flows to the water wheel 4 without interruption.
このように、各バルブをステップ毎にきちんと開閉挙
動させれば、サイホン部Ｂに従来のように真空ポンプを
設置しなくとも、導水はサイホン部を間断なく流れるか
ら、サイホン切れの心配はなくなり、非常に好都合であ
る。In this way, if each valve is made to open and close properly at each step, even if a vacuum pump is not installed in the siphon section B as in the past, the water flow will flow through the siphon section without interruption, so there is no fear of breaking the siphon, It is very convenient.

外部に排出するのを防止することができる。In addition, when the second valve 6 is inoperative, water is not guided into the penstock 3, and even when the inside of the tank 9 is set to a negative pressure, water is not guided to the siphon section B because the negative pressure capacity is small. However, since the tank 9 is not filled with water, it is possible to prevent the water from being wasted from the tank to the outside according to the present invention.

In combination, there is an effect that an excellent water intake driving can be performed without worrying about the siphon running out of the siphon section. Furthermore, when the valve cannot be opened and closed at an appropriate timing, the tank is not filled with water, and the water can be prevented from being wasted from the tank to the outside with the implementation of the present invention. .
