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 that it is structurally adapted only to the use of reciprocating motion of the waves in the vertical direction. When such movements occur, the inertial force of the moving elements when changing direction, which is accompanied by uneven movement of the magnetic field in the solenoid. In addition, the very wave exposed water surface in the vertical direction is also uneven, and so getting known devices of electric energy with stable parameters is difficult.

The objective of the invention is to develop a device construction in which oterom will be provided with a uniform speed of movement of the ferromagnetic rods relative to the solenoids, that will produce electricity with a stable, technically acceptable to consumers settings.

To achieve the technical result in the known device, comprising a housing mounted on legs, pinned inside the solenoids and placed in the solenoids ferromagnetic inside the solenoids and placed in the solenoids ferromagnetic rods, the housing is mounted on the shaft for rotation, the outer surface of the case is made kropielnicki with blades in the form of dvuhseriynogo of the Archimedes screw and provided with a collector elements, solenoids made ring, oriented and fixed in planes perpendicular to the longitudinal axis of the shaft. Ferromagnetic rods are made in the shape of a torus and provided with rollers, and the length of the body has been taken equal to not less than half the wavelength.

For the standing wave effect on the blade body length should be not less than half the average (according to observations in the region) wavelength. Each annular solenoid is assembled from two halves, pre-placing one ferromagnetic core.

Attached to the description of the drawings shows:

figure 1 - General view of the device;

figure 2 - cross section along the axis of the solenoid.

In the drawings, the following notation:

1 - about the ora;

2 - the bearing;

3 - shaft;

4 - vane in the form of the Archimedes screw;

5 - kropiewnicki case;

6 - box collector elements;

7 - wave;

8 - solenoid;

9 - rollers;

10 - ferromagnetic core.

Wave power plant comprises (1) a housing 5, on the outer kropielnicki the surface of which has the blade 4 in the form of dvuhseriynogo of the Archimedes screw pitch equal to the length of the body, and on one of the end surfaces collector elements, housed in a waterproof protective box 6. The housing 5 provided with a shaft 3 and the bearings 2 (closed from corrosive sea water), mounted on two supports 1. The shaft 3 is placed on the calm water level.

Inside the case 5 (figure 2) in planes perpendicular to its longitudinal axis, a fixed annular solenoids 8, within which is placed the ferromagnetic rods 10, provided with rollers 9, which eliminates the sliding friction of the rods on the inner surface of the solenoids.

Wave power plant operates as follows. Moving along the longitudinal axis of the housing 5, wave influences (arrows in figure 1) on the blade 4 and rotates (dotted arrow) case 5 is fixed inside the solenoid 10.

However, due to the rotation of the rollers 9 supported on the inner surface of the solenoid is 8, ferromagnetic rods 10 remain almost stationary and occupy the lower position (with a small offset in the direction of rotation due to the rolling friction in the rollers). When crossing the turns of the rotary solenoids stationary magnetic field around the ferromagnetic rods 10 in the solenoids 8, an electric current which is switched inside the housing and is output to the movable collector rings (not shown, housed in a protective box 6)to be fixed brushes (not shown) and a cable (not shown) is given to the consumer. Due to the continuous movement at a constant speed solenoids relative to the fixed ferromagnetic rods ensures stable power output from the constant parameters that are acceptable to consumers. It is possible to develop energy regardless of the amplitude of the wave.

Thanks to the installation of the power plant on the shaft for rotation, equipment blades in the form of the Archimedes screw and collector elements, perform solenoids ring with installing them in planes perpendicular to the longitudinal axis of the body and the ferromagnetic rods in the form of a torus with rollers rolling, ensures uniform transmission of wave energy device and stable power output from the acceptable to the item the user settings.

Wave power plant, including mounted on a support body fixed inside the solenoids and placed in the solenoids ferromagnetic rods, characterized in that the housing is mounted on the shaft for rotation, the outer surface of the case is made kropielnicki with blades in the form of dvuhseriynogo of the Archimedes screw and provided with a collector elements, solenoids made ring, oriented and fixed in planes perpendicular to the longitudinal axis of the shaft, and the ferromagnetic rods are made in the shape of a torus and provided with rollers, and the length of the body has been taken equal to not less than half the wavelength.
