The invention relates to the field of electrical engineering, in particular to the marine Autonomous power supply devices optical instruments, such as sea ice buoy.

Known marine Autonomous power supply unit power supply optical instrumentation buoy ice containing chemical sources of direct current (electrochemical batteries) and a mechanism to connect these batteries to discharge to the optical apparatus of ice buoy (see U.S. patent No. 3794907, 3818312; patent of great Britain No. 1357427,1368202 for 1974 to class 1; patents France No. 2193284, 2215743 for 1974 on CL H02M 7/52-1; copyright certificate №586533 for 1978 to class. 321).

The disadvantage of this self-contained power unit is that when powered by electric current optical instrumentation buoy ice energy resource data of electrochemical batteries over time decreases, which necessitates periodic replacement on new and reduces the reliability and durability of its use.

The implementation of this change significantly reduces the efficiency of the considered power plant, so as to replace the data of electrochemical batteries deliver them provides the vessel to the place of installation buoy, the rise of the buoy on deck providing a vessel disassembly containera the batteries, replacement new installation buoy and placing it in the set point on the water. After carrying out the measures described above are necessarily clarify the geographical coordinates of the place of the buoy, and in case of discrepancy between them with given coordinates assumes the exhibition of the buoy at the specified point. To perform these steps, you will need to expend significant time and service life of the production vessel, which determines the complexity of the use of the existing power plants and large financial costs associated with the use of providing a vessel.

Also known wave power plant (see patent RU-2078249 C1 "Wave power plant", 1993), the closest to the technical nature of the claimed inertial piston wave energy device (IPVEA)containing electrochemical battery and charging device, housed in a floating building, which has bearing in the form of a frame with vertical guides, a mechanical Converter comprising an inertial body in the form of cargo in contact with and having vertical guides mounted on the frame of the elastic suspension and the alternator. Elastic suspension is supplied installed on the upper part of the frame blocks and covering them with a flexible shaft that soy is ineet inertial body with elastic suspension elements. The elastic element is fixed on the base frame and is installed parallel to the guides by the inverse of their contact with the inertial body. The generator shaft is kinematically connected to the shaft of the unit, which is rotationally driven flexible shaft. Introduced electrochemical battery connected to the generator through a diode rectifier and a transformer with a variable transformation ratio, put the regulator is connected to the output of the generator and with electrochemical battery. The load device and the device to change the transformation ratio is connected to the controller.

The disadvantage of this wave power plant is that it has a very large and complex technical design: a significant number of kinematic nodes, volumetric equipment (alternator, a rectifier, a transformer, a load device, an electrochemical battery and regulator). These circumstances do not allow the specified energy installation in the internal compartment of the ice buoy, resulting in the need to use additional buoyancy located inside of this power plant and connected to the buoy electrical cable-cable. This design greatly reduces the reliability of using this is alnovol power plant in storm and ice conditions. In addition, the wave power plant comprises an electrochemical battery, which is periodically necessary to carry out its maintenance in accordance with technical specifications (TS) to the battery. These circumstances significantly reduce the efficiency and durability of this wave power plant.

The basis of the invention is a significant simplification of the technical design of wave power plants, improving the reliability and durability of these installations and simplify their operation.

The technical problem is solved by the fact that the inertial piston wave energy installation comprising a buoy, emergency power source and charging the energy device with a mechanism to connect to this source, the inertial piston made with the possibility of reciprocation up and down by the vertical motion of the buoy under the influence of the oscillation of the water surface, and spring dampers with the charging energy of the device through the connection mechanism is connected to the input of Autonomous electric source, according to the invention the installation is equipped with an air turbine, such as turbine wells, and who is goodname tubes, and inside the buoy posted Autonomous electrical source, made in the form of capacitive molecular memory based energy Dolnoslaskie capacitor, and a charging device including a DC generator relay-voltage regulator, rotor which is rigidly connected to the impeller of the turbine, and a rotation mechanism with an air capacity of cylindrical shape, within which is located an inertial piston attached at the top and bottom inside the tank by means of spring shock absorbers, upper and lower part of the vessel has holes, to which is rigidly attached vostokovedenie tube, the arrangement of which provides airflow to the blades of the turbine wheel due oscillating reciprocating movement of the inertia of the piston.

The drawing schematically shows the view stated inertial piston wave power plant with a location inside the housing offer of technical means and their structural connection.

Inertial-piston power plant comprises capacitive molecular energy storage device based on Dolnoslaskie capacitor 1, the charging device is the drive that contains the DC generator 2 relay-output control voltage 3. The rotor is of generator 2 is rigidly connected to the impeller of the turbine wells 4. The mechanism of rotation of the impeller 4 is the air tank 5 has a cylindrical shape. Inside the tank 5 is inertial piston 6, is attached at the top and bottom inner enclosure tank 5 by means of spring shock absorbers 7. In the lower and upper parts of the tank 5 holes 8, to which is rigidly attached vostokovedenie tube 9, which arrangement provides airflow to the blades of the turbine wheel 4.

The principle of the inventive installation is based on oscillatory reciprocating motion of the inertial piston 6 with spring shock absorbers 7, introduced into the air tank 5, which in turn are caused by vertical movements of the buoy, which is placed inside power plant, under the influence of fluctuations of the water surface. Fluctuations in the inertial piston 6 vertically up and down inside the tank 5 supply air flow on vozduhovodnom tube 9 attached to the holes 8, to the vane wheel 4, is rigidly connected with the rotor of the DC generator 2 with relay-voltage regulator 3. After the DC generator 2 will develop a voltage greater than the internal voltage of the energy storage device 1, will begin the process of accumulation of electric energy in the storage device 1. After a full charge gain the El power 1 relay-voltage regulator 3 DC generator 2 switches the generator 2 to the electrical circuit 10 of the connection mechanism optical instrumentation buoy.

In the absence of disturbances and, consequently, cease operation of the charging device power supply optical instrumentation buoy is carried out directly from the energy storage 1.

Inertial-piston wave energy installation comprising a buoy, emergency power source and charging the energy device with a mechanism to connect to this source, the inertial piston made with the possibility of reciprocation up and down by the vertical motion of the buoy under the influence of fluctuations of the water surface and spring dampers with the charging energy of the device through the connection mechanism is connected to the input of Autonomous electric source, wherein the plant is equipped with an air turbine, for example, turbine wells, and vostokovedenie tubes, and inside the buoy posted Autonomous electrical source, made in the form of capacitive molecular drive energy-based double-layer capacitor and a charging device including a DC generator relay-voltage regulator, rotor which is rigidly connected to the impeller of the turbine, and a rotation mechanism with an air capacity of cylindrical shape, within which is located an inertial piston, pacrep is built on the top and bottom inside the tank by means of spring shock absorbers, while in the lower and upper parts of the vessel has holes, to which is rigidly attached vostokovedenie tube, the arrangement of which provides airflow to the blades of the turbine wheel, due to the oscillatory reciprocating movement of the inertia of the piston.
