State of the art

Known hydroelectric power plant, where a chain of hydraulic structures provides the necessary pressure of water supplied to the blades of a hydraulic turbine, which drives generators that generate electricity. The required water pressure is formed through the construction of a dam, and as a consequence of the concentration of the river in a certain place, or by derivation - by the natural flow of water. In some cases, to obtain the required water pressure, both the dam and the derivation are used together. All power equipment is located directly in the building of the hydroelectric power station. Depending on the purpose, it has its own specific division. In the turbine room, there are hydraulic units that directly convert the energy of the water flow into electrical energy. There is also all kinds of additional equipment, devices for controlling and monitoring the operation of the hydroelectric power station, a transformer station, switchgear and much more.

The disadvantages of this technical solution are the following factors:

1. Often, efficient hydropower plants are farther from consumers than thermal power plants;

2. Reservoirs often occupy large territories, but since about 1963 protective structures (Kievskaya HPP) began to be used, which limited the area of the reservoir, and, as a result, limited the area of the flooded surface (fields, meadows, villages);

3. Dams often change the nature of fisheries by blocking the path to spawning grounds for anadromous fish;

4. Reservoirs of hydroelectric power stations require the use of locks to transfer ships from one pool to another.

Known paddle wheel - a type of propulsion used since ancient times to propel ships. It is a large wheel equipped with blades (plates) that are immersed in water. A paddle wheel by design Description of the invention sheet 2 is similar to a water wheel, with the only difference that it is not water that drives the wheel, but the wheel is used for movement.

An offshore wind farm is known. Offshore wind farms are built in the sea: 10-60 kilometers from the coast. Offshore wind farms have several advantages:

1) they are practically invisible from the shore;

2) they do not occupy land;

3) they are more efficient due to regular offshore winds.

Offshore power plants are built in areas of the sea with a shallow depth. Wind turbine towers are installed on foundations made of piles driven to a depth of 30 meters. Electricity is transmitted to earth through submarine cables. Offshore power plants are more expensive to build than their onshore counterparts. Generators require taller towers and more massive foundations. Salty sea water can corrode metal structures. Jack-up vessels are used for the construction and maintenance of such power plants.

The essence

The technical result, solved by the invention, is provided by the unused energy potential of sea waves.

To solve this technical problem, a wave installation for generating electricity is proposed.

The wave installation for generating electricity operates in one mode, the support post is installed deep into the ground, fixes the entire installation from diametrical displacement, a hinge is attached to the support post, and allows the frame fixed to it and the impeller, fixed to the frame through the axle, to move freely in height horizon both when entering the crest of a wave and when descending, and also provides a controlled radial displacement of the frame when adjusting the angle of the hydro attack, floats, hold the frame with a paddle wheel at the operating level of immersion in water, the paddle wheel, taking on the hydro attack of the wave, commits rotation and transmits the torque through the driven profiled wheel with teeth fixed on the axle, to the driven profiled wheel with gear teeth, which transmits the force to the generator of the installation.

In the proposed technical solution, the author finds an opportunity to express his point of view on the account of the accumulation of the hydrodynamic effect, the essence of which is the absorption of the inert forces of the sea wave by a mechanical method, with aerodynamic conditions conducive to the renewal of the ascending energy properties of the liquid medium, as systemically reversible, due to the temperature difference atmospheric flows provoking the aquatic environment.

The author finds it possible to use such an installation not only near the coastline, but also at a significant calculated distance from the coastline in the sea, in the ocean, where the sea waves of water release a large energy potential due to the larger size of the wave height, this conclusion follows from the well-known concept of sea waves and can be related to the principle of construction of offshore wind farms.
