Hydroelectric power generation system using channel for water supply

An hydroelectric power generation system with using channel for water supply, comprising:

• a water guidance unit comprising a channel for input water, the channel having an entrance connected with a water source, water from the water source entering the channel and flowing along a water flow direction, so that water in the water guidance unit reaching at least one predetermined water level;
• a one-way gate disposed in the channel, the one-way gate having a top end disposed on the water guidance unit along a horizontal axial direction, the one-way gate being switchable between an open position and a close position, a height of the one-way gate corresponding to a reachable water level of the channel in which the one-way gate is disposed;
• when the one-way gate is at the open position, the water flowing into the channel unidirectionally passing through the one-way gate;
• when the one-way gate is at the close position, the water is prevented form flowing back toward the entrance;
• and
• a plurality of power generation units peripherally disposed on an edge of the water guidance unit;
• when the water in the water guidance unit reaches the at least one predetermined water level, the water of the water guidance unit flows to the power generation units that are disposed on the edge of the water guidance unit to conduct a power generation operation,
• wherein each power generation unit comprises
• a tank body,
• a siphon body,
• an operation speeding mechanism, and
• a generator;
• the tank body comprises an input portion, and the tank body is connected with the water guidance unit,
• when the water of the water guidance unit reaches a predetermined water level, the water from the water source enters from the input portion into the tank body to be accumulated therein;
• the siphon body comprises
• a drawing segment,
• a connection segment, and
• a dropping segment,
• the drawing segment vertically disposed in the tank body and having an inlet on a bottom end of the drawing segment, the dropping segment vertically disposed out of the tank body and having an outlet on a bottom end of the dropping segment, the connection segment connected between a top end of the drawing segment and a top end of the dropping segment, the inlet disposed higher than the outlet, such that the water in the tank body is sucked into the drawing segment from the inlet through a siphon effect, and passes through the connection segment and the dropping segment to be continuously discharged by the outlet;
• the operation speeding mechanism comprises a plurality of rotation axles that are sequentially and transmittably combined;
• a preceding rotation axle is combined with the dropping segment, so that the water continuously discharged by the dropping segment drives the preceding rotation axle to rotate with a first rotation speed, and a succeeding rotation axle combined with the preceding rotation axle is driven by the preceding rotation axle to rotate with a second rotation speed, wherein the second rotation speed is higher than the first rotation speed;
• the generator comprises an output axle transmittably combined with the preceding rotation axle, so as to be driven by the preceding rotation axle to rotate with a third rotation speed, wherein the third rotation speed is higher than the second rotation speed, and the generator is driven by the output axle to rotate with the third rotation speed for generating power.
