MAINTENANCE SYSTEM OF HELICAL TURBINE

摘要

Disclosed is an assembled helical turbine system, which can strengthen weakenings of a housing assembly, and simultaneously can be easily assembled/disassembled. The assembled helical turbine system includes a helical turbine formed with a plurality of blades in such a manner as to continuously generate a rotational force under unidirectional or multidirectional fluid flow; the housing assembly including a plurality of bearing spiders for rotatably supporting a rotating shaft constituting the helical turbine, and a plurality of side posts for connecting and fixing the respective bearing spiders to each other, the side posts being fixed in such a manner as to radially protrude by a predetermined length from peripheral surfaces of the bearing spiders; filling members for filling and reinforcing spaces between the peripheral surfaces of the bearing spiders and outlines of protruding portions of the side posts; and a housing supporter for supporting the housing assembly in such a manner that the housing assembly can be inserted into and withdrawn from the housing supporter, the housing supporter having catch grooves that are recessed in a shape corresponding to stoppers, that is, the protruding portions of the side posts, so as to fix the stoppers. In this way, the weakenings generated in portions where the bearing spiders are joined to the side posts can be reinforced by the filling members, and thus the portions where the weakenings are generated can be strengthened.
