Patent ID: 8297052

Claim:
A hydraulic electricity generator having a drive device having at least one compressing unit, and each one of the at least one compressing unit having a storage tube having a top; a bottom; a chamber defined in the storage tube to store water; an inlet pipe connected to the storage tube near the bottom, communicating with the chamber and having a free end; an outlet pipe connected to the storage tube near the bottom, communicating with the chamber and having a free end; and a nozzle mounted on the free end of the outlet pipe; and a compressor connected to the top of the storage tube and having a piston slidably mounted in the chamber of the storage tube to push the water flowing out of the storage tube from the outlet pipe; a hydro-generator connected to the at least one compressing unit of the drive device and having a hollow casing having two opposite sides, and one of the opposite sides of the casing connected to the free end of the outlet pipe of the storage tube of the at least one compressing unit, wherein the nozzle of each one of the at least one compressing units is extended into the casing to inject the water into the hydro-generator to generate electricity; a hydraulic turbine rotatably mounted in the casing and having a spindle rotatably mounted in the casing and having an outer end extended out of the casing; and multiple blades formed around the spindle of the hydraulic turbine; a windmill mounted securely on the outer end of the spindle of the hydraulic turbine to provide another rotating force to the hydraulic turbine; and a draining pipe connected to the other opposite side of the casing of the hydro-generator to allow the water flowing out of the hydro-generator; and a recovering tank connected to the draining pipe of the hydro-generator and the inlet pipe of the at least one compressing unit of the drive device to let the water that flows out of the hydro-generator flow back to the chamber of the storage tube of the at least one compressing unit.
