Abstract
The invention discloses a tidal range buoy power generating device. A large buoy is made into a circular shape or a square shape; a circular hole is formed in the center of the large buoy; and a pile passes through the circular hole to be diffused into a coastal sea-floor mud layer with a large tidal range. By using the lifting process of the buoy during the tidal change, a reciprocating pumping device is driven by a connecting rod and a rocker arm, and is connected with a spray pipe of a hydroelectric generator on the shore through a pipeline, so that a generator is pushed to generate power. Because the change process of the tidal range is inconsistent and the effluent of the pumping device is discontinuous due to slack tide phenomenon during turning of the tide, the power-generating quality is unstable and the power generation is temporarily stopped. Due to the arrangement of a compensation mechanism consisting of a pressure tank, a reservoir and a water tank on the upper part of the buoy, and a control air pipe and a pneumatic control valve, the tidal range buoy power generating device overcomes the defect that the pumping device discontinuously pumps through the regulation of the air pipe and the pneumatic control valve by utilizing the water flow subjected to the engine work to store and release energy in the pressure tank, the reservoir and the water tank. Therefore, the aim of really realizing tidal range power generation is fulfilled.
