Description

at the motor ends at the upper end of said additional coupling. The control engine and the tail of the engine are driven by the engine at the upper end of the additional links. The motor also includes a vertical strut, vertically movable devices and devices operating from wave energy, tides associated with these movable devices, a head of the upper end of this support, supporting star couplings, chains connecting said mobile devices and elongated along the couplings, supporting counterbalanced balance, motors between the specified clutch and the control mechanism.

The main disadvantage of the known device is its extreme structural complexity, which is manifested in the presence of a large kind of various mechanical and kinematic joints of a large number of technical elements: gears, boat and ball floats, couplings, chains, gears, mobile devices, a control mechanism and etc., which is associated with large energy losses in overcoming friction forces at the sites of the indicated compounds, leading to a significant decrease in efficiency and reliability.

The purpose of the invention is to increase the efficiency of the installation.

This is achieved in that a wave power plant comprising a support fixed to the bottom of a reservoir and a projection protruding above the water level, an electric generator fixed to the support, and floats located around the support, fixed around its perimeter by means of articulated levers, the free shoulders of which are kinematically connected by means of gearing to an electric generator, equipped with a bearing assembly fixed on the central part of the support, the gears are made in the form of a chevron wheel and brackets with ends bent inward, at the wheel is mounted on the bearing assembly for rotation in the horizontal plane, the brackets are attached to the free shoulders of the levers with the possibility of alternating interaction of their ends with the teeth of the wheel, and the floats are fixed on the levers by hinges with the possibility of longitudinal movement and fixing,

This embodiment of the wave power plant allows, in comparison with the prototype, to significantly simplify its design, thereby increasing its reliability and, accordingly, the value of efficiency.

Such a design of a wave power plant was not previously known. It 5 meets the criterion of significant differences. In FIG. 1 shows a wave power plant, side view; in FIG. 2 - the same, top view.

The wave power plant contains a bearing assembly 2 fixed on the central part of the support 4, a gear train made in the form of a chevron wheel 3 and brackets 4 with the ends 5 bent inward mounted on the bearing

5 node 2 with the possibility of rotation in the horizontal plane under the influence of brackets 4, contacting by means of their ends 5 bent inward with the wheel 3, attached to the free shoulders of the levers 6 with the possibility of alternating interaction of their ends 5 with the teeth 7 of the wheel 3. floats 8, fixed on levers 6 by means of hinges 9 with the possibility of their longitudinal movement and fixation. The shaft 10 of the impeller 3 is connected by means of a clutch 11 to the shaft 12 of the electric generator 13 with a speed converter (not shown).

The wave power plant operates as follows.

0 Waves, acting on the floats 8, cause the rotation of the levers 6 installed in the articulated supports. When lifting the float 8 to the crest of the wave - the bracket 4 with its upper end 5 acts on the upper

5, the inclined plane of the tooth 7 and slides down along its plane, turning the wheel 3. When lowering the float 8 into the trough of the wave, a similar effect of the lower end 5 of the bracket 4 on the lower

0 inclined plane of the tooth 7, causing the impeller 3 to rotate in the same direction. The torque of the wheel 3 through the clutch 11 of the shaft 12 through the speed converter transmits 5 s to the electric generator 13.

The synchronism and sequence of action of the bent ends 5 of the brackets 4 on the inclined plane of the chevron teeth 7 of the wheel 3 and the magnitude of the forces of their impact

0 are controlled by varying the distance of the floats 8 relative to the support 1 by the levers 6 with fixation.

The economic efficiency of the proposed wave power plant

5 is determined by limiting the loss of wave energy and applying speed control to the chevron wheel and generator shaft.
