ABSTRACT:
An adaptive control artificial wavemaking device comprises an air blower as shock wave source. According to the invention, the device further comprises a control system consisted of a float, a sensor, a control circuit and electromagnetic actuators; butterfly valves; and air chamber for generating shock wave. When the sensor receives signals from the flaot, the signals are transferred through the control circuit to actuate the electromagnetic actuators to control opening and closing of said butterfly valves to enable the air chamber to generate a shock wave which is in resonance with the water wave. The device may further comprises an oscillator for generating shock wave of a given frequence during starting. The device according to the invention has the advantage of similified structure, low mangufacture cost and low energy consumption, thus it may be widely used for aquatic breeding, sport, recreation and medical facilities.
