FIELD: power engineering.SUBSTANCE: device belongs to the field of wave power engineering. Electric generators with hydraulic motors driving them are located outside the floats 3 and are connected to hydraulic motors by oil lines, and the device itself is rigidly connected to the sea bottom by means of a base in the form of a pipe with a flange in the middle part and a pipe bridge at the top. Screw with a keyway on its surface is fastened to the bridge, and the nut connected to it is made in the form of a pinion-bushing, on the collar of which there is a bearing for mounting the housing. Its movement is provided by a drive mounted on a plate fixed to a bushing with a key inside the hole for engagement with the said screw. Bushing itself is mounted on the end of the pinion-bushing. Outside the housing, there are eyes ends fixed for the axles: the upper – for hydraulic cylinder 13, the lower one T-shaped – for attaching the rocker arm in the form of a stepped shaft. Adapter 15 is pivotally mounted on a larg
