WATER STREAM EJECTION DEVICE, AND WATER STREAM POWER GENERATION SYSTEM EQUIPPED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a water stream ejection device capable of being environment friendly and achieving inexpensive power generation, and to provide a water stream power generation system equipped with the same.SOLUTION: A water passage 90 is formed in the ground under a road 80, and water is charged inside the water passage 90. Inside the water passage 90, a water stream ejection device 10 and power generation turbine 130 are installed, and the water stream ejection device 10 ejects the water at the power generation turbine 130. Because a weight of an automobile 150 is applied to a treadle 70 when a front wheel of an automobile 150 rides on the treadle 70, a hydraulic piston 21 is depressed. On this occasion, because the water is vigorously ejected from an ejection nozzle 41 of the water stream ejection device 10, the water inside the water passage 90 flows in the ejection direction, and rotates the power generation turbine 130 installed downstream. Thus, power is generated.
