WAVE FORCE PUMP ACTIVATED BY FORCE OF WAVE

摘要

PROBLEM TO BE SOLVED: To enable a wave force pump to be enlarged easily by forming a cylinder for sectioning a pump chamber freely elevatingly so as to form a float integrally to this cylinder, on a piston part formed on the upper end of a hollow piston tube connected to a water supply/discharge chamber and provided in erection close to the water surface. SOLUTION: When waves hit the outside of a concrete caisson 2 to raise a water level S1, a float 16 and a cylinder 17 are also raised to have the inside of a pump chamber 51 expanded so as to cause vacuum action. Accordingly sea water in an outer ocean 39a flows in a wave force pump 1a via a water intake tube 4. And simultaneously with this event, the water staying inside of a hollow piston tube 10 is sucked in the pump chamber 51. Then, when the water level S1 is lowered, the float 16 and the cylinder 17 are also lowered, and a force in the direction of compression works on the water staying inside of the pump chamber 51. And this water is pressed in the hollow piston tube 10 and the water staying in the hollow piston tube 10 is pressed in a water feed/exhaust chamber 50 so that the water in the water feed/exhaust chamber 50 is fed out to a water feed tube 31.
