Power device for actuating irrigation pivots, which permits the use of excess pressure in a network of water supply in different distributions of intakes to the plots, formed from a turbine (2) with actuator mechanism (3) that regulates the distribution of the flow interspersed in the water supply to the irrigation system (1), having been associated with said turbine (2) a transmitter mechanism (9) to supply the mechanical energy that originated in the turbine to a power generator of continuous current with energy production regulator (10), associated with a group of energy accumulation batteries (11) which are in turn connected to an inverter group (12) from which the electric power supply in the command and control box (14) as well as in the corresponding motors (16) of the towers of the irrigation pivot are established.
