諸性能を確保せねばならず、ランナーの上流又は、下流
の水路を拡大しなければならす水力特性上、および経済
上好ましくない。Conventionally, as an axial flow hydraulic machine, there is a tubular type water turbine installed on the shaft of a flow path as a generator. Tube 2 type water turbines are generally used for low head water turbines. However, although the head is low, it is not possible to increase the rotation speed of the C2 equipment. For this reason, the diameter of the generator must be increased to ensure the required electrical performance, which is unfavorable in terms of hydraulic characteristics and economy since the waterway upstream or downstream of the runner must be enlarged.

、発電機の保全と細軸性向上と機器の大型化のためには
、漏水のない構造が必要であった。However, in such a structure, since the circumferential speed of the water turbine runner is high, it is difficult to completely seal the flowing water with the seal of the runner. In addition, water leakage from the seal can cause damage to the generator coil, so how to prevent water leakage was a major technical problem for this type of water turbine. 0]! -21 If an attempt was made to increase the size of equipment, the circumferential speed of the runner would increase and the amount of water leakage would increase, so C=upsizing was a problem. For this reason, In
, In order to maintain the generator, improve the thinness of the shaft, and increase the size of the equipment, a leak-free structure was required.
本発明は、上記問題点を解決するためになされたもので

を介して支え５Ｂにより保持されている。Four guide vanes, 5A and 5BVi support, and 6 represents a container for separating the rotor 2 and stator 1 and protecting the stator 1 from the influence of running water. The excitation electricity supplied to the rotor 2 is supplied from the outside through the support 5A and one runner blade. The rotor 2Vi is housed in a container 6 while maintaining a relationship, and the stator 1 is arranged on the outer periphery of the container 6, facing the ball number 2 of the rotor 2. Rotor 2
The sealing cover used for the rotor 2 has a sealed structure to reduce the influence of running water, and to prevent electrical leakage. The cover surface is made of a material that does not damage the rotor 2 and has a smooth structure so that there is little frictional resistance with the fluid when the rotor 2 rotates in the fluid. The runner 3 is the bearing 7
It is held by a support 5B via.

回転子Ｃ−４えるトルクを制御する。An excitation current is supplied from the outside of the rotor coil 12, and the rotor rotates together with the runner due to the torque given by the flowing water, and an induced current is generated on the stator side to generate electricity. The flow rate is adjusted by the guide vane Kuzuji in response to the load fluctuation of the generator.
Controls the torque applied to rotor C-4.

No seals are required, and as a result, the peripheral speed of the rotor can be increased, making it possible to use Sumire Otani.
