Each pontoon has the ability to independently move relative to the inertial body to actuate the pump. The inertial body is provided with an inertial plate to save the inertial body is essentially stationary in the water regardless of the predominant wave frequency and/or amplitude. Inertial plate is connected with the inertial body, at least one axis and has the ability to move relative to the inertial body. When the primary engine is towed through the water, the inertial plate rises to reduce the resistance. Then, when the primary engine is in its operating position, the plate is lowered into the water to keep the inertial body is essentially in a stationary position.

Basically, the energy derived from such primary engine from wave energy, is provided as the low-frequency form of waves. Energy must be converted into a useful frequency and/or frequency type before using it.

Energy, going from relative movement between the rafts and the mooring device, is converted into mechanical, hydraulic and/or electrical energy. Batteries are used for regulation and energy storage.

Patent application in Germany (DE-A-2921381) also describes a device in which the movable pontoons connected to the platform, and a hydraulic pump is used for pumping oil. Provided cameral.

The present invention is to eliminate the disadvantages of the primary engines of the energy waves of the prior art and provision of an improved mechanism of energy extraction and damping for such a device.

Accordingly, the present invention provides a mechanism of energy extraction and damping for the primary engine, working from wave energy having at least two pontoons, which are moved one relative to another to perform work as described in the accompanying paragraphs patenting.

The primary engine can be attached to the anchor to below the bottom of the sea or fastened in any other manner, for mooring. In the work, for energy production, primary motor fully moored, but the mooring must be performed so that the inertial body had some freedom of vertical vibrations, rotations in the horizontal direction and/or fluctuations in the limits provided by the inertial plate.

In a preferred example of the device of the present invention provides the primary engine that runs on the energy of the waves, containing two movable pontoon separated floating inertial Cola actuation of the pump, thus, the inertial body has inertia plate designed to hold the inertial body essentially motionless in the water, and the mechanism of energy extraction and damping, comprising: means for converting movement of the pontoons in the energy of the hydraulic pressure, the tool contains at least one linear oil pump, which transfers the energy through the barrier transfer to sea water, means for straightening energy pressure in unidirectional form management tool for regulating the power pressure and feedback tool for varying the parameters of the damping means damping.

Preferably, the axis is movable to change the distance between the plate and the inertial where, and the freedom of movement of the pontoons relative to the inertial body. Linear hydraulic pumps directly affect the freedom of movement of oscillating pontoons.

The feedback tool contains several adjustable valve for regulating the back pressure in one or each linear hydraulic pump, thereby varying the parameters of the damping relative movement between the inertial body and each pontoon having an independent movement.

Preferably, the damping parameters are varied by changing the back pressure acting on one or each linear pump.

The hydraulic network is provided for extracting power hydraulic pressure of the oscillating relative movement of the pontoons. The network contains at least one linear hydraulic pump that can be connected between the inertial body and a pontoon, and a discharge pipe, in which the energy of the hydraulic pressure transmitted from the pump through the hydraulic lines, accumulated during movement of the pump between the extended position and the retracted position.

Preferably, for each pump, the network includes first AK is the provisions in the retracted position, second battery for receiving power hydraulic pressure when the pump is forced to move from the retracted position into the extended position, and plenty of shut-off valves, ensuring the removal of energy extracted from the pump discharge pipe.

The hydraulic network is preferably divided into two parts, one of which uses the stored hydraulic medium, for example oil, and the other uses water, which floats the primary engine, and both parts are isolated by the barrier of the transfer, located in each battery.

Several pumps are connected to the pressure pipe.

Network hydraulic system doubled to extract energy from the relative motion of the inertial body and the other pontoon.

One or each discharge pipe provides an environment under pressure (preferably water) to drive a turbine to extract electrical energy or to supply water under high pressure in a reverse osmosis system with the aim of making potable water from sea water.

The invention will then be explained more specifically with reference to the accompanying drawings, which show exclusively through with what is side view of the primary engine, working on wave energy, Fig. 2 is a view in plan of the primary engine, Fig. 3A-3C are a side view, a view from the end and view in plan, respectively, the inertial body of the primary engine, which show in detail the hydraulic network that contains the mechanism of energy extraction and damping, Fig. 4 is a schematic representation of a network hydraulic system for one line of the pump and Fig. 5 is a schematic view in perspective of the mechanism of energy transfer.

With reference to the drawings, and first to Fig. 1 and 2, the primary engine includes a floating inertial body or barge 1 with floating pontoons 2, 3, which are connected with the possibility of independent rotary movement. Each pontoon 2, 3 has the hinges 5 for connection with the respective joints 7 of the inertial body. The movement of the pontoon 2, 3 relative to the inertial body 1 under the influence of ocean swell or waves actuates the pump 10 provided between the inertia body 1 and the respective pontoons 2, 3.

The width of the pontoons 2, 3 can be selected to meet the necessary requirements for power, typical frequency waves and/or amplitude at any selected location, preferably with C is rinnovo of the housing 1. In the primary motor is fixed anchor or attached in some other way, to avoid drift, and due to the location of the pontoons relative to the inertial body, that is, when they are mutually parallel longitudinal axes, the primary engine itself is located at a right angle to the direction of the waves or swell, which leads to maximum energy recovery from the independent functioning of the pontoons 2 and 3, which move relative to the inertial body. The mount does not affect the relative position of the inertial body in the water and does not interfere with the ability of the damping device (described below) to hold it essentially stationary in a vertical position in the water.

The inertial body 1 provided with a device to hold the housing 1 essentially stationary in the water. The device comprises two pairs located at the distance of the supports 15A, 15b, 16A, 16b, which are mutually parallel. Each pair of supports connected with the inertial body at one end and connected with the inertial plate 20 on their lower ends. The device may ascend or descend relative to the inertial body using winches and/or hydraulic means (not shown). Uprazheniyami inertia of the housing 1. The inertial body 1 is essentially a hollow vessel having at least two swivel 24 on each side for connection with the pontoons 2, 3. Also provided by the elements of the gearing 26 for linear pump 10, which are mounted between the said elements of the gearing 26 and the corresponding elements of the gear 26a on the pontoons 2, 3. Pumps 10 are appearing and being compressed by relative movement between the inertia body 1 and the respective pontoons 2, 3, producing hydraulic pressure in the hydraulic network, which is shown in detail in Fig. 4 and 5.

The hydraulic network is provided for extracting energy from ocean waves or swell the manipulation of energy hydraulic pressure from the relative motion of moving pontoons 2, 3. For each of the pontoon 2, 3 includes a hydraulic network. Each hydraulic network contains at least two pump 10, the first battery 32 for receiving the power hydraulic pressure when the pump 10 is shown with the power of the nominated position (position a, Fig. 4) in a laid back position (position B, Fig. 4), the second battery 34 for receiving the power hydraulic pressure when the pump 10 with the power derived from the output valves 39, allow accumulation of such energy in the pipe 35. In one part of the network is stored hydraulic medium, for example oil, is used for energy transfer, and in another part of the network as a hydraulic fluid sea water is used. Two environments are separated by a barrier transfer 40 located in each battery 32, 34. Each battery includes a container with a capacity of 28 litres, designed for the pressure of 345 bar. In a particularly suitable device, each primary engine has three pumps in front and two pumps in the back, and they can be distributed between two networks of the hydraulic system.

As described in detail in Fig. 4 and 5, when the linear pump 10 is actuated by movement of the pontoon, this action displaces up to 5 gallons (22,74 liters). Sea water is drawn into the first battery 32 through the lower valve 37, acting in the same direction, a negative pressure (vacuum) created by the displacement of the pump from a to C. Hydraulic oil is displaced from the pump to the second battery pack 34, displacing sea water on the other side of the barrier transfer 40 through a check valve in the discharge pipe 35, which is designed for 300 bar. On the contrary, when the pump 10 is moved from In to a sea water inlet is tecnam sea water in the first battery 32 through their respective shut-off valve 39 into the pipe 35. Due to the reciprocating movement of the pump 10, the pressure energy is accumulated in the pipe 35 for regulated use. Sea water under pressure may be made adjustable to drive turbines for the energy conversion of pressure energy into electric energy, or can be used directly in reverse osmosis desalination.

The extracted pressure energy can also be used to change the damping characteristics of the primary engine by varying the relative freedom of movement of the pontoons 2, 3 relative to the inertial body 1. The application of back pressure to the pump 10 increases the overall stiffness of the primary engine. This rigidity in turn affects the change of the damping parameters for the design and the overall efficiency of the energy of the primary engine. Actively adjusting the back pressure acting on the pump 10, the conventional technologies of regulation, it is possible to obtain the required effective energy and damping parameters for the primary engine, respectively, prevailing weather, wave height and the amplitude of the waves and ocean swell.

The present invention is particularly applicable to the production of energy or can be used for direct production of drinking water. The invention uses a minimum number of moving parts, it has the strength and reduces the overall cost and operation cost of the primary engines. A means of varying the back pressure in the hydraulic system provides for changing the damping. Back pressure can be regulated using a feedback circuit that is controlled by a valve that can be done by means of remote control. The primary engine can be used independently or can be linked with several other primary engines that are controlled remotely and standard management technologies and telemetry.

Of course, it is understood that the present invention is not limited to the specific described here details of which are given here only as examples, and possible modifications and changes within the scope of the invention defined in the accompanying paragraphs patenting.
