The invention relates to hydropower, in particular to the wave energy installations.

The known installation for conversion of wave energy conversion mechanism of the movements which is located above the water surface, but not using the kinetic energy of horizontal motion of the waves.

Closest to the proposed connecting to a generator, the float on the end of the rod. The disadvantage of the float has a shape and angle, preventing the use of horizontal movement of waves [1].

The purpose of the invention is to reduce fluctuations in the rotation speed of the generator, using the kinetic energy of horizontal motion, waves, increasing capacity and efficiency of the installation.

This goal is achieved by the fact that the floats - medium mounted on the ends of the rods, and the side connected rigidly to the rod is extended, have the shape of a triangular prism with exposed faces. The ends of all the rods are placed on a common axis and independent in their relative movements, and a sufficient space between the side floats provides free passage of waves on the average float.

Fig. 1 - section a-a (see Fig. 2); Fig. 2 is a top view of the installation; Fig. 3 - stage cross-section B-B (see Fig. 2).

The apparatus comprises a frame with a platform 1, angular and internal struts 2 resting on the ground. Axis 3 with the attached bevel gears 4, 5, 6, 7 and rigidly connected with them wheels 8 hrapovic mechanisms, passes through the ends of the uprights 2. Gears 4 and 5, 6 and 7 pairs are in engagement with the bevel gears 9 and 10, the connection is her 15 on the shaft 16. On this shaft is mounted a flywheel 17, the coupling shaft 18 is connected to a generator 19. Average float 20 are mounted on the ends of the rods 21, the rods are placed on a common axis. The opposite ends of the rods with the holes pivotally connected with the middle rack in the lower portion. The lever 22, to host a focus ratcheting mechanism 23 and the latch 24, one end of which is mounted on a shaft 3, the second end pivotally connected to a thrust of 25 with the rod 21. Pivotally connected to the lever 22, the rod 25, the portion of the rod 21, the rack form a hinge chetyrehzvennoj (parallelogram). The side floats 26 are placed at the ends of the elongated rods 27, the circuit operation of the float 26 is the same as the float 20.

Installation design works as follows.

This object is placed so that the direction of the velocity of the wave is preferably coincident with the longitudinal axis of the installation, which corresponds to the coincident longitudinal axes of the floats and the wave front. The float 20 and the floats 26 are independent in their relative movements; they can be both in the upper position (on top of the wave) and lower (depression), or to move in opposite directions. For example, the float 20 is moving down, this si placed on the flywheel 17 and the generator 19. Gear 6 while rotating in the "idle" stroke. If in this period, the floats 26 are moving up, it works ratchet gear mechanism 4, which transmits torque to the gear 9; gear 7 is in "idle" stroke. The probability of float 20 and floats 26 in the same position, i.e. in the same phase points of the waves is very small. Therefore the reduction of the fluctuations of the rotational speed of the generator will be carried out not only by the flywheel, but different height position shifted relative to each other floats in the direction perpendicular to the wave front. Floats in the shape of a triangular prism with exposed edges and the position of the rod close to the middle line of the waves allow us to use the energy of the shock wave in the plane of the float to rise. Therefore, to the ends of the rods is attached not only lifting force of the float, but the force of the blow. When the wave motion in the opposite direction (off shore) float will also absorb the shock waves.
