Claims

[Scope of utility model registration request]

A guide vane that is fixedly installed inside the water conduit pipe and rotatably supports the runner vane, and a flange formed on the outer peripheral surface of the water conduit pipe and the outer peripheral surface of the suction pipe that communicates with the water conduit pipe by sandwiching the runner vane. An annular stator held between the formed flange portion and a front part 2 inside the stator.
a rotor integrally fixed to the outer periphery of the inner vane; and a rotor protruding from the lalange portion of the water conduit that faces the side end surface of the rotor, and the side end surface of the rotor and the inner circumferential surface of the fixed rotor. a seal ring that partitions an annular space surrounded by the flange portion of the water conduit 9 and the outer peripheral surface of the water conduit into an inside and an outside; and a seal ring that is bored in the guide vane and opens at one end toward the suction pipe. a suction passage whose other end opens to the inner circumferential surface of the water conduit pipe; a drain pipe whose both ends communicate with the other end of the suction passage through the inner annular space and the introduction pipe; and the outer side. A sealing structure for a hydraulic electric machine, comprising an additional space and a water supply pipe, both ends of which communicate with the upstream side of the water conduit and are provided with a foreign matter removal filter.
