Description

 The invention relates to marine energy, and in particular to devices for converting waves, natural local and ocean currents into electrical energy in the open sea.

 A well-known marine-based power plant containing an anchored floating means, an electric generator located in its hull, and a counterweight (USSR copyright certificate 1333817 A1, IPC 7 F 03 B 13/12, published on 08.30.1987, 2s.).

 Such a power plant has low power and limited functionality.

 The objective of the invention is to increase power and expand functionality.

 The specified technical result is achieved due to the fact that the generator located in the housing is made in the form of an air turbine electric generator of direct current, a through shaft is made in the body of the floating vessel, the counterweight in the water column is equipped with a rotor with vertically arranged blades kinematically connected to the multiplier and the DC generator located in the inner cavity of the counterweight, while on the deck of the floating means around the through shaft mounted corrugated pneumatic chambers belt volume, the upper elements of which are pivotally connected to removable consoles, rigidly fixed on the counterweight, and the pressure chambers of corrugated pneumatic chambers are connected to an air turboelectric generator, electrically connected to the rotor generator with vertically arranged blades and an external electric network, a cutout is made in the diametrical plane of the body of the floating vessel with a through shaft, providing laying "on the move" counterweight using a winch and a cargo cable.

 The invention is illustrated by graphic material, where the drawing schematically depicts a sea-based power plant, general view (partial breakouts).

 Sea-based power plant contains anchored buoyancy 1, counterbalance 2 with stabilizer ribs 3, a direct current turbo-electric generator 4, variable volume air corrugated chambers 5, consoles 6, a cardan joint 7, a direct current generator 8, a multiplier 9, a through shaft 10, a winch 11, cutout 12, shaft 13, cargo cable 14, rotor 15, anchor cables 16, gravity anchors 17 and external power cable 18.

 It is advisable to use round-shaped floating means as carriers of elements of a power plant, the diameter of which should be equal to or less than 1/2 of the wavelength that dominates the sea.

 The power plant operates as follows.

 In the area of constant operation, the power plant is towed afloat with a raised counterweight 2. After anchoring and installing the counterweight in a vertical position by means of a winch 11 and cable 14, the power unit is firmly fixed to the removable consoles 6 on the counterweight and is put into operation. When rotating on a stream in the water column of the rotor 15, the shaft 13, the multiplier 9 and the electric generator 8 are rotated.

 On a wave, during the rolling of buoyancy 1, the consoles 6 in a vertical plane alternately act on the upper elements of the corrugated pneumatic chambers of variable volume 5, the latter alternately suck, then pump air under pressure into a turboelectric generator 4, which is automatically connected to the electric generator from the electrical side 8 rotors 15 and external power supply. The generated electricity can be transmitted via cable 18 to the receiving coastal terminal or used by consumers directly on board the buoyancy 1.
