っている。2. Description of the Related Art On the earth, a large number of hydroelectric power stations are provided by a water turbine and a generator utilizing a head of water. Water turbines generate output according to head and flow rate, and water turbines used for power generation are roughly classified into reaction type and impulse type, and reaction type turbines are mainly used for medium to low heads. In general, when a reaction-type turbine is used in a hydroelectric power plant, large-scale civil engineering works such as a dam, a water channel, a penstock, and a turbine generator room are required. Therefore, the unit price per kW of the generated power is very high.

Therefore, development costs of such hydropower stations need to be kept low. In order to minimize development costs, it is important to minimize civil engineering construction costs, and the turbines must be compact and integrated. However, it is a fact that the output is not obtained by a water turbine at a location point having a low head and a small amount of water.

いて説明する。The reaction type water turbine 6 is provided with a vertical shaft-integrated generator 12 via a speed increasing device as a transmission device 11 for transmitting the rotation of the reaction type water turbine 6, and the speed increasing device is attached to the shaft of the runner 7. The fixed large-diameter pulley 13 is transmitted to an intermediate small-diameter pulley 15 via a V-belt 14,
At 6, the speed is transmitted to the small-diameter pulley 17 fixed to the rotating shaft of the generator 12 to increase the speed. Of course, the generator 12 is stored in the storage case 20 in order to prevent water contact. The hydraulic power generator is provided with a hook 18 for suspension. Next, a method of using the reaction water turbine provided with the weir plate of the present embodiment will be described.

河川の壁に設けた溝の中に堰板４を入れて堰板４が川底
に着底するまで吊降ろす。A wire rope is hung on a hook 18 of the hydroelectric generator, and the direction is determined so that the generator 12 is on the upstream side and the weir plate 4 at the tip of the draft tube 2 is on the downstream side. Put the weir plate 4 in the inside and suspend it until the weir plate 4 reaches the bottom of the river.

The water does not flow into the inside, the water is blocked, the dam is automatically formed, the water level rises, the water overflows the weir plate 4, and the hydroelectric generator is submerged.
【００１７】堰板４の周囲からの漏水が無いように設置

した水車を設計すれば良い。When the hydraulic power generator is installed in this manner, a drop occurs between the level of the water surrounding the turbine 6 and the level of the water outlet 3 at the tip of the draft tube 2. Therefore,
When the guide vane 9 is opened, water flows in from the guide vane 9, passes through the runner 7, enters the draft tube 2, and flows out from the water outlet 3 at the tip while reducing the flow velocity in the draft tube 2. I do. During this time, water acts on the runner 7 to rotate the water wheel. In addition, since it is necessary to keep the head constant, the flow rate is adjusted by the guide vanes 9 so that the inflow water amount and the outflow water amount become the same. Of course, since the flow rate at the location point has been measured in advance, it is sufficient to design a water turbine that matches the flow rate.

In addition, when removing hydropower equipment due to changes in site conditions such as floods and waterway repairs,
What is necessary is just to suspend the hydraulic power generation device by hanging a wire rope on the hook 18 and remove it.

Therefore, the generated output can be easily adjusted by the height of the weir plate attached to the water turbine. In addition, since it is a flush type that does not require a large-scale civil engineering construction work, its dispersal is easy.
