(57) Abstract:

The invention is intended to convert the energy of ocean waves and tides and can be used to drive generators and the various mechanisms by means of hydraulic actuators. The unit consists of private piers, pontoons, rocking and pumps. In addition, it is equipped with an oil tank with filter and accumulator. While the pumps are made of oil, and the pontoons are provided with rods pivotally attached to the support posts of the rack. The last hanging rocking with blades mounted interoperable with oil pumps, placed on the rack, for the discharge of oil from the oil tank in General, a hydraulic accumulator communicated with the reservoir, running hydro, providing a stable oil pressure in the hydraulic accumulator when the change efforts of the action of the waves and tides. Under the rocking chair has the guide groove with the base and the guide walls. Hydraulic equipment is isolated from the external environment that simplifies maintenance and ensures reliable operation. 4 Il.

The invention relates to hydropower and projektagentur and various mechanisms by means of hydraulic actuators.

Known power Converter, which is designed for the energy of the perturbed water surface and consists of a floating device made in the form of two pontoons attached to the hollow plate, with a gap between them equal to half the wavelength of the excited surface. Hollow plate contains air caps with flaps and swinging on a rack installed on the bottom of the reservoir, and to the top of the rack attached to the pumps connected with a hollow plate [1].

The power Converter is difficult to make, inefficient and not suitable for use in marine conditions, where the wavelength is not constant, and, in addition, this device does not use the energy of tides.

Also known wave engines, consisting of a frame with rails and float interacting with ratchet, torque shaft [2].

These engines are inefficient because of the limited size of the float and unreliable in conditions of high corrosiveness of seawater.

The aim of the present invention is to convert the energy of ocean waves and tides in hydraulic efficiency.

This goal done with rods, pivotally attached to the support posts of the rack, and from the shore to the pier suspended rocking with blades mounted interoperable with oil pumps, placed on the rack, for the discharge of oil from the oil tank in General, a hydraulic accumulator communicated with the reservoir, running hydro, sequentially automatically disables or enables consumers of oil, while maintaining stable oil pressure in the hydraulic accumulator when the change efforts of the action of the waves and tides, and under the rocking chair has the guide groove with the base and side walls to guide the water of the tide on the rocking chair.

The invention is illustrated in the drawing, where Fig.1 shows a General view of the installation of Fig.2 is a cross-section on the support posts of the rack of Fig.3 is a top view of the guide chute of Fig.4 is a hydraulic diagram installation.

Installation (Fig.1) consists of a closed rack 1 with the supporting poles 2, pontoons 3 with rods, pivotally attached to the supporting uprights 2 by means of shaft 4 (Fig.2), extension cable 5 with the rod 6, the oil pump 7, is suspended from the uprights 8 on the overpass, rocking 9 with blades on the support 10, no oil 15 and an additional arc walls 16 (Fig.3) install oil pump double action. Hydraulic equipment consists of an oil tank 17 with a filter, hydraulic accumulator 18, the collector 19 of the hydraulic valve 20, the safety valve 21, the valves 22, 23 gauge, oil lines: 24 suction, discharge 25, branch 26, the drain 27 (Fig.4).

The device operates as follows.

With the passage of the waves and the tide pontoons 3 and rocking 9 lead in the work of the oil pump 7, 11, forcing oil from the oil tank 17 in the hydraulic accumulator 18, from which the oil enters the reservoir 19 with hydraulic valve 20 configured for different pressure drops to consistently automatic disconnection and connection of consumers oils to maintain a stable pressure in the hydraulic accumulator 18 when the change efforts of the action of the waves and tides. When used in the installation of oil pump dual action of the guide groove 13 is made with an additional arc walls 16, providing additional water inflow of the tide on the rocking chair during low tide.

Thus, this setting can be used to drive electric generators and other mechanisms, the hydraulic actuators are connected to the valve and is to use the energy of sea waves and tides instead of other expensive sources of energy to drive electric generators and various mechanisms by means of hydraulic cylinders.
