Abstract:
1. An air-blower tidal power generation device, comprising: an air-blower mechanism comprising at least one pumping device, a buoy, and an air conduit, the pumping device comprising a cylinder and a stationary barrel, the cylinder comprising a metal layer, an epoxy resin layer, and a plastic sheet layer, the metal layer being an inner lining and having an outer circumference surrounded by the epoxy resin layer, the epoxy resin layer having an outer circumference surrounded by the plastic sheet layer, the metal layer having an inside surface movably fit over and engaging the stationary barrel, the cylinder located at one end of the pumping device and fixed to the buoy, the stationary barrel located at an opposite end of the pumping device and being in fluid communication with the air conduit, the air conduit being connected to and in fluid communication with an extension tube, the air conduit having an end forming an opening inside which a first check valve is mounted, a second check valve being arranged in the extension tube; a rack that carries the air-blower mechanism therein; and a power generation mechanism comprising a constant-pressure and pressure-regulation device and a power generator having an air-driven turbine, the constant-pressure and pressure-regulation device being connected to and in fluid communication with the extension tube; wherein the buoy is adapted to move up and down by tides to drive the pumping device for cyclically drawing and pumping air, the air being preserved in the constant-pressure and pressure-regulation device to provide a constant pressure for subsequent and stable supply of airflow to the turbine for driving the power generator to generate power.
