- a lower chamber in which a counterweight is arranged. It is an air chamber whose interior is mainly a generator and a large tonnage weight, hung from an axle or pulley or connected to it by some method of mechanical transmission. This upper axis is mechanically connected to a second axis located in the lower part of the chamber.
- This lower axis maintains part inside the chamber in which the weight is located, defining a sealed chamber, preventing any mechanism inside the housing from being in contact with water.
- the other part of the shaft comes out of the housing by means of gaskets or seals, maintaining the system's tightness.
- this central part which is outside the chamber, is a cable or chain pick-up mechanism.
- This cable or chain is anchored, so that the rise in the water level produces a rise in the housing that acts as a buoy or float, which rotates the lower axis transmitting the movement inside the housing, turning to turn the axis of the upper part through the mechanical transmission and producing the rise and fall of the weight inside the chamber.
- the vertical movement of the weight inside the air chamber is used to produce electrical energy, transforming the potential energy acquired in the rise in the counterweight.

- collectors (18) are located in an artificial air chamber (36) that minimizes the corrosive effects of seawater and allows the lower shaft (16) and all the mechanisms it carries to be in optimal lubrication conditions.
- anchoring cables (30) are wound that are attached at their other end to the bottom of the sea at a anchoring point (21).
- the air outlet and inlet port (29) of the intermediate chamber (24), has a non-return valve (31), operated by a float (32), which prevents water from entering the turbine (4) and / or in the compressor (6).

- the enclosure (1) being immersed in a fluid, seawater, experiences a thrust equal to the weight of the volume of fluid dislodged. Without swell, this thrust exerted by seawater on the enclosure shell is counteracted by a weight that is ballasted at the bottom of the sea and other elements that are inside it, so that the casing shell, outwardly, it behaves like a float on the sea surface.
- the complete set which acts as a float, oscillates more or less similar to the wave movement that occurs in the sea.
- Said lower axis (16) rotates the axis of the upper part (10) through the mechanical transmission, producing the more or less vertical rise of the weight (12) inside the chamber.
- the ballast force exerted by the weight (12) on the bottom of the sea is higher, because as the shaft rotates and the weight rises, the radius of the chain picker (18) increases.
- the movement of the weight is increased, so that at the beginning of the movement the weight moves less length than at the end for the same movement of the enclosure.
- the generators will be disconnected electrically so that they extract energy during the period of descent and achieve that the weight increases as much as possible during the period of ascent.
- the generators do not work during the period of rise they behave like a dead mass, but depending on the conditions of the waves they can work taking advantage of the energy that the weight presents.
- the compressed air in the intermediate chamber reducing the total thrust of the housing and favoring the weight reduction.
- the energy of that compressed air can be harnessed by causing that compressed air to exit through a turbine (4), which in turn is connected to another generator (5). The movement is repeated according to the wave movement of the sea.
- the proposed device is configured from a float constituted by an enclosure (1) that is divided into two or more chambers, comprising at least one air chamber, in which a superior generator is provided (8) and a lower one (14) at a weight (12) of large tonnage, which is hung from an upper axis (10) and is connected to a lower axis (16), whose central part of said lower axis (16) ) comes out of the housing with a anchoring cable (30); and, in said air chamber or a different one, a compressor (6) and a turbine (4) associated with a third generator (5); and, at least, another chamber, with water inlet and outlet holes (22) to be filled or emptied partially or totally of air and water depending on the time of raising or lowering the water level, and opening through an outlet port of air (29) to induce the exit or entry of water.
