(SU1770601-A1)      At the moment of lifting of a float member on a wave, a counterweight falls freely until its axle contacts a fixed stop. The counterweight accumulates energy during falling depending on its initial linear speed. During rotation of the counterweight through 180 deg. during lifting, the counterweight takes up a horizontal position on the other side of the axle and the sum of the energy accumulated by the counterweight during falling and the energy of the wave is transmitted through the member.    During rotation of the counterweight through 180 deg. during the next lifting of the axle with the counterweight, the energy is extracted with the counterweight in a horizontal position. The counterweight on the axle is lifted to an assigned height limited by a limiter on a movable support. Rotation of the counterweight is carried out during the period of lifting of the member on a wave, to accumulate additional energy from the wave. Bul. 39/23.10.92    (EP446356-B1)      A method of wave energy conversion by a vibration generator (2) placed on a floating means (1) and equipped with at least one unbalanced weight (3,13,32) rotatably mounted on a shaft (4,12,31), characterized in that elevating the shaft (4,12,31) with the unbalanced weight (3,13,32) above the floating means (1) to a specific height (H) letting the shaft (4,12,31) with the unbalanced weight (3,13,32) fall freely from this height (H) till the contact with the floating means (1) the unbalanced weight (3,13,32) retaining its horizontal position with respect to the floating means (1), and letting the unbalanced weight (3,13,32) accumulate energy, taking energy off as the unbalanced weight (3,13,32) turns to 180deg around the shaft (4,12,31) thereof and as the shaft (4,12,31) with the unbalanced weight (3,13,32) are elevated, the unbalanced weight (3,13,32) still being arranged horizontally, and in which case the free fall of the shaft (4,12,31) with the unbalanced weight (3,13,32) till the contact with the floating means (1) and the turn of the unbalanced weight (3,13,32) are performed as the floating means (1) rises with a wave, thus ensuring that, during the turn of the unbalanced weight (3,13,32), the energy accumulated by the unbalanced weight (3,13,32) during its free fall and turn is summed up with the energy of the wave, transmitted via the floating means (1) to the unbalanced weight (3,13,32) the elevation of the shaft (4,12,31) with the unbalanced weight (3,13,32) to a specific height (H) and placing of the unbalanced weight (3,13,32) to its initial position are performed as the floating means (1) sinks with the wave, in case the fluctuation frequency of the floating means (1) diminishes, the height of elevation of the shaft (4,12,31) with the unbalanced weight (3,13,32) should be increased and visa versa.
