The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

The invention discloses a novel efficient power generation device of tide-wave energy, comprising a floating body provided on the sea surface, a support device provided on the coast, and a lever device connecting the floating body with the support device; the lever device comprises a force transmission rod and a main lever provided with a connecting device; the power generation device comprises a driving device, one end of which is connected with the connecting device to rotate the driving device and the other end is connected with the external electric motor device. The invention enables the up-and-down motions of the floating body through the acting force of the tide, to drive the up-and-down motion of the force transmission rod. The lever device connected with the support device by hinge, rotates the driving device through the connecting device, to rotate the external electric motor device to provide electric power.

A tidal energy converter has a pivoting lever that moves in response to tidal fluid moving other elements on the converter. The pivoting lever can be operatively coupled with an electricity generator to produce electricity. Namely, the pivoting lever may be coupled to an air source and compress the air to create a compressed air. The compressed air may be used to power an electricity generator. The pivoting lever is moved by fluid that empties from a feed tank to a spill tank. There may be one or more ballast tanks connected to the feed tank and/or the spill tank. Some of the feed tanks work in opposing unison with one of the ballast tanks.

MECHANICAL ENGINE FOR THE GENERATION OF ENERGY THROUGH WATER MOVEMENT, refers to a mechanical motor (1) to (41), with their auxiliary sets, with the objective of generating mechanical and electrical energy, or both, being plants electric lines with this system can be built on the banks or inside the sea, river or islands, where the cost benefit of the energy by the conventional way, does not become compensating, or practically inaccessible places, but that have waves, tides, or level differentials in waters. As these sources of energy, in water there are in abundance on the planet, possible future plants of this system, may be more spread out, and in greater quantity, thus reducing the number of posts, towers, compensation equipment, components, and transmission wires. In case of use in water navigation, this engine can be used to replace, totally or partially, conventional fuels and engines, for mechanical handling, and the generation of electric energy on board.
