The use of a tidal wave impact on a cone nozzle with a low efficiency is a feature of this wave installation. Having such a number of check valves, a wave installation uses the energy of only one wave. This wave installation operates in a certain wavelength range limited by the distances between the flanges.

The invention in comparison with the prototype wins in terms of efficiency.

The proposed hydropneumatic wave pump repeatedly uses the energy of a moving wave, the flexible piping system of which uses the energy of the wave front, concentrating it in the receiver. Hydropneumatic wave pump operates in a wide range of waves.

The indicated technical result is achieved in a hydropneumatic wave pump containing a flexible piping system with a non-return valve and positive buoyancy provided by floats, a floating water intake with a water intake funnel held by an anchor according to the invention is connected to the piping inlet, the flexible piping system is made of a decreasing section to the outlet, to the inlet pipelines connected floating intakes made in the form of water-air intakes connected by a cable, the ends which are held by anchors, piping outputs are connected to a common manifold through a tap and a non-return valve, the collector is connected to the receiver, inside which there is a float water level regulator connected to water and air valves, the receiver has two outlets: the upper part after the valve is for air, in the lower part after the valve is for water, the water-air intake is made in the form of a hollow float, a funnel with a nozzle for fastening the pipeline and a counterweight plate forming the float chamber, and the plate provides Mount cable and counterweight to the orientation of the water-intake.

In addition, part or all of the water and air intakes are anchored.

In addition, a mesh filter is installed on the funnel of the water-air intake.

In addition, boom protection is installed between the water and air intakes, and an additional tap below the water level with a tap has been made in the receiver.

In addition, a turbine with an electric generator is connected to the air outlet.

In addition, a hydrogenerator of electric energy or a pipeline for lifting water into the upper pool is connected to the water outlet.

In addition, the first 10-15 meters are made with a flexible pipe that does not change the cross-section, the rest with a flexible sleeve with integrated floats.

Hydropneumatic wave pump uses the energy of the wave front by a flexible piping system, multiple energy extraction of a moving wave, collection and separation of oil products from the surface of the water. High efficiency at a pressure of several bars allows you to raise water to the upper pool or generate electricity by rotating the hydrogenerator, rotating the pneumatic turbine to generate electric energy, through the tap for petroleum products equipped with a valve, you can periodically or continuously discharge petroleum products under pressure into the storage tank due to movement water and air aeration occurs. Hydropneumatic wave pump operates in a wide range of waves.

A hydropneumatic wave pump, located at a distance from the shore, uses the energy of wave rise, while water with oil products delayed by the boom through a strainer that traps the floating debris, the funnel of the flooded water-air intake held by the anchor enters a flexible pipeline, forming a column of water with positive buoyancy and creates pressure in the pipeline, unlike the prototype, using a shock of a breaking wave with low efficiency. In a decaying wave, a column of water under its own weight sags somewhat and, due to the removal of the funnel, fills the pipeline, which does not change the cross section, with air. The next incident wave fills the pipeline with water, compressing the air in the pipeline, adding up the pressure in the pipeline. To compensate for changes in the height of the water columns due to air compression, the pipeline is made to reduce the cross section to the outlet to the collector. Thus, the energy of moving waves is repeatedly used by the piping system, in contrast to the prototype using the shock of the breaking wave. The pipeline is connected to the collector on pontoons through a valve for servicing individual pipelines and a non-return valve that prevents backflow of water. The collector is connected to the receiver, in which the separation of water, air, oil products, as well as the concentration of energy of the piping system. Two outlets are made in the receiver, the upper with a valve for air, the lower with a valve for water, the valves are connected to a float-operated water level regulator in the receiver. An additional outlet with a tap below the water level serves to discharge oil products. Air and water under pressure are supplied to the turbines of the electric power generators.

The water-air intake is a float with a funnel for receiving water and air with a strainer for collecting garbage and a pipe for attaching the pipeline, the cavity of the float, a plate with a counterweight in the lower part and fastening elements of the cable and boom protection. A float in calm water ensures that the funnel rises slightly above the surface of the water, when the incident wave is driven by moving the funnel forward and the water-air intake of the counterweight is oriented, the water is drawn into the pipeline; when the wave is falling, the funnel is moved forward and the wave moves into the pipeline.

The collector is a pipeline of increasing cross section towards the receiver, to which pipelines and the receiver are connected through taps and check valves. The collector is raised above the water surface by pontoons fixed by anchors or in another way.

The receiver is a sealed tank inside which there is a float connected to the upper valve, which regulates air pressure and the lower valve, which regulates the water level, bends for the valves are made for water and air under pressure for further use, below the water level in the receiver there is a branch for discharge of oil products.

The invention is illustrated by drawings.

In FIG. 1 shows a water-inlet front view, in FIG. 10 is a side view, which is a float, consisting of, a funnel 1, on the inlet of which is installed a strainer 6, the cavity of the float 3, the plate 4 forming the chamber of the float. A pipe 2 is welded to the funnel 1 for connection with the pipeline. Plate 4 is used to hold oil products, attach boom protection and a cable, counterweight 5 provides orientation of the water-air intake. 7 fasteners for bonding protection and cable.

The water-air intake 8, the boom protection float 9, the boom protection curtain 10, the boom protection counterweight 16, the flexible conduit of decreasing cross section with floats 11, valve 12, non-return valve 13, manifold 14.

In FIG. 3 shows a top view of a hydropneumatic pump in a static state, in figure 12 the end of the hydropneumatic pump. Water-air intakes 8, boom protection floats 9, flexible pipe 11 of decreasing cross section with floats, valve 12, non-return valve 13, manifold 14, pontoon 17, float 18, boom protection anchor 19, receiver 20.

In FIG. 4 shows a receiver 20 representing a tank connected to a manifold 14 for supplying water and air, inside which is a float 21 connected to a valve 22 regulating the water level and valve 23 regulating the air pressure. Outlets 24 were made behind the valves for a hydrogenerator of electric energy 25 or lifting water into the upper basin, 26 to an air turbine of an electric energy generator 27, for petroleum products 28 with a crane 29 for periodic or controlled discharge of petroleum products.

Pa fig. 5 shows a wave hydropneumatic pump in a static state. In the absence of disturbance, the water-air intakes and pipelines float freely on the surface of the water, and the funnel 1 (Fig. 1, 11) is located above the surface of the water due to the buoyancy force of the float and the leveling force of the counterweight 5. The condition of the pipeline, possibly partially filled with water, is not critical.

To explain the principle of operation, a system of four U-shaped liquid pressure gauges 30 is presented, connected in series between each other and the receiver 31 with a pipe 32 (Fig. 7). In the absence of air pressure supplied through the pipe 32, the pressure gauges show zero pressure. When air is supplied through the nozzle 32 (Fig. 8), a column of water is formed in the first pressure gauge maintaining the pressure in the receiver 31 and compressing the air in the second pressure gauge than increasing the pressure in the receiver 31. As a result, the pressure in the receiver will be equal to the sum of the pressure in the manometers. With further injection of air through the pipe 32, air bubbles passing through the water of the first, and then the second, etc. pressure gauges will create a limit pressure equal to the sum of the pressures of all pressure gauges (Fig. 9). Now, if this system, due to its buoyancy, copies the movement of waves, air and water periodically enter the receiver.

In FIG. 6 demonstrates the principle of operation of the wave hydropneumatic pump. When an incident wave passes through the funnel 1 (Fig. 1, 10) of the water-air intake 8 (Fig. 2, 11, 6), water enters the pipeline 11 (Fig. 2, 11, 6), the amount of which is determined by the diameter of the pipe 2 (Fig. 1, 10) and wave height. At the upper point of the wave, the funnel of the water intake 1 (Fig. 1, 10) due to the buoyancy force of the float of some removal of the funnel forward and the counterweight 5 (Fig. 1, 10) is above the water level and the water flows under its own weight below the pipe of the water intake , part of the pipeline is filled with air. With a decaying wave through the funnel 1 (Fig. 1, 10) due to the buoyancy of the float of the water-air intake, some removal of the funnel 1 (Fig. 1, 10) forward and the counterweight 5 (Fig. 1, 10) pipeline 11 (Fig. 2 , 11, 6) is filled with air. The process is cyclical. As a result of this process, the entire pipeline consists of columns of water 33 (Fig. 6) on the incident side of the wave and columns of air 34 (Fig. 6) on the incident side of the wave. With an increase in pressure in the pipeline, air is compressed, a decrease in the cross section of the pipeline leads to an increase in air columns and water columns, therefore, the pressure in the pipeline to the outlet to the collector. When water flows in a pipeline at high air pressure, aeration is saturated with oxygen. The outputs of the pipelines are connected to a common collector 14 (Fig. 2, 11, 6) through a valve 12 (Fig. 2, 11, 6) and a check valve 13 (Fig. 2, 11, 6) to eliminate mutual influence and maintenance. The collector is mounted on the pontoon 17 (Fig. 6) and connected to the receiver 20 (Fig. 4). The receiver is a sealed tank 20 (Fig. 4) connected to a collector 14 (Fig. 4, 6) for supplying water and air; it is used to separate water, air and oil products into fractions. Inside the receiver there is a float 21 (Fig. 4) connected to a valve 22 (Fig. 4) that regulates the water level and a valve 23 (Fig. 4) that regulates the air pressure behind the valves made bends 26 and 24 (Fig. 4) for water and air . Below the water interface, a branch 28 (Fig. 4) is made for the discharge of oil products with a tap 29 (Fig. 4) for periodic or controlled discharge of oil products into the tank. The outlet 24 (Fig. 4) is connected to a hydrogenerator of electric energy 25 (Fig. 4) or a tube for supplying water to the upper pool, the outlet 26 (Fig. 4) with an air turbine of the electric energy generator.

The energy of sea waves is concentrated wind energy and its potential is huge. A sea wave two meters high has a power of 70 kW per linear meter of the wave surface. Attempts are now being made to extract this renewable energy. For example, with a wave of two meters and a wave displacement rate of 1 meter per second and a pipe diameter of 0.2 meters, approximately 31 liters per second or 0.031 cubic meters per second are pumped to the collector. At a pressure of 0.2-0.3 MPa, this corresponds to 6-9 kilowatts per pipeline, the use of a system of 100 pipelines per 100 meters allows you to get a power of 600-900 kilowatts. The calculation is approximate according to the laws of physics. The input diameter of the pipeline is 0.3 meters and a length of 100 meters, and the first 10-15 meters have a flexible size that does not change the cross-section of the pipeline, the next 85-90 meters can be made in the form of a sleeve with integrated floats.

The calculation is approximate with rounding on one pipeline.
