流体システム
Document Type and Number:
Japanese Patent JP7431137
Kind Code:
B2
Abstract:
To provide a fluid system capable of arranging a fluid machine at an optimum submersion depth different between when a water turbine function is exerted and when a pump function is exerted.SOLUTION: A fluid system includes: a support mechanism 20 that supports a fluid machine 30 to be movable in a vertical direction in running water; a float part 36 that is provided on the fluid machine 30 and can generate buoyancy capable of moving the fluid machine 30 upward in the running water; and a compression spring 23 that is provided on the support mechanism 20 and can exert downward urging force according to the buoyancy on the fluid machine 30 and the float part 36. The fluid machine 30 is configured to switch between a water turbine function and a pump function according to a water level of the running water, and is configured so that it can be located at a water turbine submersion depth A when the water turbine function is exerted and it can be located at a pump operation submersion depth, which is deeper than the water turbine submersion depth A, when the pump function is exerted.SELECTED DRAWING: Figure 2
