  • Patent number: 8807917
    Abstract: Disclosed is an assembled helical turbine system, which can prevent its assembly/disassembly from being hindered by a rotational force generated during the assembly/disassembly process. 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; a housing assembly for rotatably supporting the helical turbine while surrounding the helical turbine; stoppers formed on a peripheral surface of the housing assembly in such a manner as to protrude to a predetermined height from the peripheral surface; 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supporter for supporting the housing assembly in such a manner that the housing assembly can be inserted into and withdrawn from the housing supporter, the housing supporter having catch grooves that are recessed in a shape corresponding to the stoppers so as to fix the stoppers.

  • Patent number: 8740545
    Abstract: 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 comprises the housing assembly including a plurality of bearing spiders for rotatably supporting a rotating shaft of a 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supporter for supporting the housing assembly in such a manner that the housing assembly can be inserted into and withdrawn from the housing supporter, the housing supporter having catch grooves that are recessed in a shape corresponding to stoppers.
