As preferably, oil hydraulic cylinder is fixed in the brace bottom.
As preferably, be provided with displacement transducer in oil hydraulic cylinder.Displacement transducer can be put the displacement distance of plate regulating pushing rod in the Accurate Measurement oil hydraulic cylinder, and the distance that the both sides push rod moves is equated, thereby accurately controls the displacement distance of pendulum plate.
As preferably, the brace bottom is connected with wave energy conversion hydraulic pressure installation one end, and wave energy is changed hydraulic pressure installation and is obliquely installed.Wave energy conversion hydraulic pressure installation and conventional buoyancy pendulum-type wave energy apparatus are similar, wave energy can be converted to electric energy or other forms of energy.
As preferably, controller is connected with PC.The tidal signal that PC first records according to liminmeter calculates the mean tide tlevel value in the certain hour interval, then calculates the value of pendulum plate needs displacement according to mean tide tlevel by built-in in advance program, then by controller output signal to putting the plate controlling device.
As preferably, controller is the PLC controller.The PLC controller is programmable logic controller (PLC).
As preferably, tidal level is counted the pressure type liminmeter.The pressure type liminmeter is placed near buoyancy pendulum basis, install simple, be difficult for impairedly, the variation of tidal level can cause liminmeter position variation in water pressure, thereby can measure the variation of tidal level.
According to technological scheme of the present invention, the buoyancy pendulum device that adapts to the tidal level variation is processed the tidal signal that receives by PC, calculating the pendulum plate needs the value of displacement, and then export the value of displacement to pendulum plate controlling device by the PLC controller, by pendulum plate controlling device, the position of pendulum plate is regulated, realized that the pendulum plate adapts to the function that tidal level changes.Because the pendulum plate can be according to the SEA LEVEL VARIATION adjusted position, more conventional buoyancy pendulum device, the hydrodynamic performance that adapts to the buoyancy pendulum device of tidal level variation will significantly improve, and for to be converted into available energy fully, the energy waste in whole conversion process significantly be reduced wave energy.
