<p><P>PROBLEM TO BE SOLVED: To provide a hydraulic power generating device for increasing production of electricity, by utilizing conventional hydraulic power generating equipment. <P>SOLUTION: In the hydraulic power generating device, water is guided by a pipe 2 having water head difference to rotate a hydraulic turbine, so as to drive a generator (not shown in the figure) for generating electric power. The hydraulic power generating device is provided with a vacuum pump 5 for making suction force act on the water in the pipe 2 from the downstream of the hydraulic turbine 3 to increase a rotational speed of the hydraulic turbine 3. A vacuum chamber 4 communicating to the inside of the pipe 2 is disposed to the downstream of the hydraulic turbine 3, and a vacuum pump 5 is connected to the vacuum chamber 4. A drainage pump 6 is disposed to the downstream of the vacuum chamber 4 or the inside of the vacuum chamber 4 to perform drainage for securing a nearly vacuum area in the vacuum chamber 4. <P>COPYRIGHT: (C)2004,JPO</p> |
