The control of the wheel helicoidale to produce, in a pool, a water current trend and the formation of waves

摘要

P the invention relates to a command for a helical gear carried out in the manner of a helix of a boat, actuated by a motor. / p & & p & according to the invention, this detector comprises an electric or electronic, of height of the water level, which can be adjusted on the height of the desired level, and which is connected by electrical paths and a delay of the pulse, to a pulse generator which controls an electromagnetic coupling to coast used in and out of the circuit, by means of which the helical gear, or the operation of the boat is coupled to the actuating motor and is controlled at the rate of the movement of the waves, that is - to - say started or stopped by the movement of the waves. / p
