Protective structure for water turbine runner coupling bolt

Protective structure for water turbine runner coupling bolt

The utility model relates to a protective structure for a turbine runner coupling bolt. At present, for a water diversion type power station with the large silt content, silt enters a fit clearance between a coupling bolt screw and a nut along with water flow, and therefore a bolt is jammed. The pro...

description The utility model relates to a protective structure for a turbine runner coupling bolt. At present, for a water diversion type power station with the large silt content, silt enters a fit clearance between a coupling bolt screw and a nut along with water flow, and therefore a bolt is jammed. The protective structure for the turbine runner coupling bolt comprises a protective cover body, the protective cover body is composed of a hexagon nut protective cover (1), a threaded rod protective cover (2) and a flange plate (3), the flange plate is connected with the hexagon nut protective cover, the hexagon nut protective cover is connected with the threaded rod protective cover, and the hexagon nut protective cover, the threaded rod protective cover and the flange plate are of an integrated structure; the top of the threaded rod protective cover is fixedly connected with a cover body (4), a threaded hole (5) is formed in the circle center of the cover body, a locking bolt (6) is screwed into the threaded hole, and
