Siphonage hydroelectric generation device with screw turbine

A siphonage hydroelectric generation device comprising:

• a water source having a first water level;
• a storage tank fluidly communicating with the water source and having a second water level being lower than the first water level of the water source;
• a filter disposed between the water source and the storage tank;
• at least one channel fluidly communicating with the storage tank and extending obliquely and downwardly from the storage tank;
• at least one screw turbine disposed in the at least one channel and extending obliquely and downwardly, each of the at least one screw turbine including
• a spinning shaft;
• and
• a spiral blade extending spirally;
• at least one power generator connected to the at least one screw turbine;
• and
• at least one first siphon pipe, the at least one channel fluidly communicating with the storage tank via the at least one first siphon pipe;
• each of the at least one first siphon pipe having
• a siphoning inlet end portion inserted into the storage tank and extending upwardly;
• and
• a siphoning outlet end portion fluidly communicating with a corresponding one of the at least one channel, extending upwardly, and fluidly communicating with the siphoning inlet end portion, the siphoning outlet end portion having an end opening being lower than the second water level of the storage tank.
