SELF-SIPHON TYPE WATERWHEEL GENERATOR

摘要

PPROBLEM TO BE SOLVED: To provide a self-siphon type waterwheel generator for automatically discharging air accumulated in a draft pipe connected to a waterwheel by using a bleeding action of an ejector for starting the waterwheel. PSOLUTION: The draft pipe (3) is connected to the waterwheel (2) suspended at a high water level side, a discharge port (3c) of the draft pipe (3) is submerged at a low water level side, and a suction port (27b) of an ejector pipe (27) disposed at a lower part of the draft pipe (3) is connected to the rear of an axial flow runner (19) of the waterwheel (2). Further, a rear end (27c) of the ejector pipe (27) is suspended at the low water level side, and a bleeding pipe (23) connected to a pipe top part (3a) of the draft pipe (3) is connected to a suction air ejector (25) of the ejector pipe (27). When water flows into the ejector pipe (27), accumulated air in the draft pipe (3) is sucked into the suction air ejector (25) to generate a syphon action to operate the waterwheel (2) interlockingly connected to a generator (15).
