A bypass 4 that communicates between the front and rear portions of the valve 3 is provided, and a second control valve 5 and a water turbine 6 are provided on the downstream side of the second control valve 5, respectively, to channel flow rate fluctuations in the fluid pipe line 1. The detector 2 detects the detection, and the control panel 7 accordingly controls the control boxes 3 and 5 to adjust the flow rate of the fluid flowing through the bypass 4, and the energy of the fluid flowing through the bypass 4 is used to drive the water turbine. 6, which activates the generator 8 to convert it into electrical energy and convert this electrical energy into electricity.

The control valves 3 and 5, which are used to adjust the flow hi of the bypass 4 in order to effectively drive the outgoing corner 2 and the water turbine 6, are required to have at least four control valves, and Since the control of the control valves 3 and 5 by the panel 7 becomes extremely complicated, there is a drawback that the device becomes extremely expensive and complicated.

されたものである。Furthermore, since there is an air portion and a liquid portion in the sealed tank, the tank is configured to hold a certain amount of air. For example, in the atmosphere - even if the liquid level of the fluid corresponding to the fluid pressure on the upstream side of the liquid pipeline becomes considerably high, a sealed tank must be provided for the fluid pressure on the upstream side. This allows the position of the sealed tank, that is, the installation height of the pipeline, to be set as low as possible.The flow rate required to drive the water turbine can be adjusted according to fluid pressure fluctuations in the fluid pipeline, that is, fluctuations in the flow M. On the other hand, the flow of interest is caused to overflow from the closed tank to an overflow pipe communicating with the discharge side of the water turbine and to be returned to the downstream side of the fluid pipeline.
