The invention relates to hydropower, namely the conversion of the energy of motion of waves on the surface of oceans, seas and other large bodies of water into electricity.

A device for energy from sea waves, containing floating craft, the actuator is placed in a closed housing, isolating the upper part of the stem, to which is rigidly attached ferromagnetic rods oriented parallel to the stem and placed in the solenoids attached to the housing, while the upper part of the stem is made of ferromagnetic material, and the housing is the outer shell of the solenoid (UK application No. 1271490 And IPC NC 35/00, publ. 12.04.1972 year).

A disadvantage of the known device is adapted to modify the amplitude of the waves. At low amplitudes of the waves stroke and associated ferromagnetic rods placed in the solenoids, is limited because of the magnitude of the amplitude and the action of the inertial forces resulting from the reciprocating movement of the craft during the direction change. If the amplitude of waves exceeding technically possible stroke and ferromagnetic cores, they are fixed with the passage of the top and bottom of the wave. This complicates the development unit of electricity. In addition, do not use the energy spread is anemia waves.

The invention solves the problem of providing a given stroke and uniform rate of movement of the ferromagnetic cores of the solenoids at different largest amplitudes of wave energy propagation.

To obtain the desired technical effect in the known device, comprising a closed housing mounted on supports attached to the inner surface of the housing solenoids and placed them in the ferromagnetic rods, a rod associated with ferromagnetic cores, the body is made of floating and is mounted on bearings for rotation. The axis of rotation of the housing is oriented at an angle to the axis of the rod. The rod is located inside the housing is mounted on casters and spring-loaded on both ends. The body is equipped with bladed propeller mounted on the axis of rotation of the body, and a support equipped with a collector elements.

Attached to the description of graphic materials shown:

16 - the direction of rotation of the housing-float;

α - the maximum angle of inclination of the axis of the rod from the horizontal plane in which is located the shaft 11.

The device (1) consists of a closed housing-float 5, made with the possibility of rotation around the axis of the shaft 11, the bearings 1, mounted on supports 12. From the rolling waves on the body of the float 5 is rigidly fixed multi-blade screw 2, and on the opposite side of the box 10 collector items (rings and brushes). Inside the float 5 is rigidly fixed to the solenoids 4 and the axis of the roller 7 in contact with the latter is a rod 6, reported to the mounting plate 13 with ferromagnetic rods 3 arranged inside the solenoid 4. With both ends of the rod 6 has projections that are included inside of the springs 8, and the case is equipped with glasses 9, the internal diameter of which corresponds to the outside diameter of the springs 9. The axis of rotation (shaft 11) of the device is located at an angle α≈30-35° to the longitudinal axis of the hull of the float 5 and coincident with the axis of the rod 6. The shaft 11 is set at the level of calm water.

The device operates as follows. When the wave propagation 15 (2) in the direction 14 it affects the screw 2, with the giving torque, resulting in increased speed of rotation is rigidly connected to a housing-float 5 in the direction 16. After gathering wave device rotates by inertia until the impact of the next wave, etc. When you rotate the device around a horizontal axis (the shaft 11) body-float 5 and placed in it a rod 6 with ferromagnetic cores 3 occupy different positions, the inclination of their axes relative to the horizon varies from a maximum equal to the angle α (even-numbered position in figure 2), to zero at the location of the axis in the horizontal plane (odd positions).

When the horizontal position of the axis of the stem 6 is the last in the middle of the body of the float 5 and supported equally tucked springs 8. When the inclination of the axis of the rod 6 up to the maximum angle α it slides on rollers 7 down, compressing the spring 8 located below the shaft 11, while the opposite spring expands. Then decrease the angle of the axis of the rod 6 from α 0° the lower spring gives the accumulated elastic energy, and the rod moves upward to the original (horizontal) position. Then the cycle of movement is repeated in the opposite direction. Thus, the shaft 6 and connected with the plates 13 ferromagnetic rods 3 are in constant motion, raising the solenoids 4 electric is the current cue with certain parameters.

It is the embodiment of the casing combined with a floating tool and supply it with content, placing the entire rod inside the housing and its supply with springs at both ends, the embodiment of the casing for rotation on bearings, supply it with a screw and collector elements, the location of the axis of the shaft and the housing at an angle to the axis of rotation, the supply of bearings, roller bearings provide a full stroke and ferromagnetic cores of the solenoids irrespective of the amplitude of the waves allow us to use the energy of wave propagation and to generate electrical energy with technically acceptable parameters.
