The invention relates to the field of marine hydropower and can be used to build a hydroelectric plant uses the energy of breaking waves.

There are various types and designs of hydroelectric power plants that use the energy of breaking waves, directly resulting in the movement of the working shaft of the current generator (see SU 802450; 07.02.1981; F03B 13/12), and for recovery of various pumps (pumping) of sea water in the tanks to the reservoir (see SU 1437476 A1, 15.11.1988, IV 9/08), which is raised above sea level and the accumulated water is fed to the blades of the turbine working. The disadvantages of such hydropower plants should include the inevitability of a large investment in equipment shoreline, construction and installation of ramps for lifting and accumulation of water (see SU 783406, 30.11.1980, IV 9/08), creating channels or tunnels for water supply.

The prior art pump lifting water for marine tidal wave hydro containing pontoon float and a hollow truncated cone with wide bottom intake and top narrow feed part, which merges into a vertically directed pipe and rigidly attached to the pontoon to float with the possibility of reciprocating movement up and down under the influence of breaking waves (see EN 59940 U1, 10.01.2007, F03B 13/12). The disadvantages of this pump ledue is attributed to the presence of the mating parts and low efficiency.

The objective of the invention is to eliminate the above disadvantages.

The objective of the invention is achieved due to the fact that the pump lifting water for marine tidal wave hydro containing pontoon float and a hollow truncated cone with wide bottom intake and top narrow feed part, which merges into a vertically directed pipe and rigidly attached to the pontoon to float with the possibility of reciprocating movement up and down under the influence of breaking waves, according to the invention the pump is equipped with a system of hollow truncated cones with the internal taper of from 0.025 to 0.01, which form a single rigid structure and fixed and pre-filled water containers, each of which is omitted mobile, not strictly associated with building the capacity of the cone with the ability to divert water up in the next adjacent upstream capacity, and in the first capacitance upper edge is located at the water level with the possibility of constant filling movement of the tidal waves, and each of the cones is equipped with a separator non-return valve installed on the transition from cone to the pipe.

Figure 1 shows the working body of the pump - full cone.

Figure 2 shows schematic diagram of the construction of the pump.

For lifting water and the direction of its working on the stake is about turbines proposed pump the principle is based on the fact that if the full truncated cone 2, figure 1, having the actual mass mkunder the action of its own gravity open wide end with diameter D will dive into the water with velocity V1passing water through itself, the narrow upper end with a diameter d, the velocity V2the water discharge from the cone is greater than the speed of V1the magnitude And equal to

A=V2-V1.

The value of the variable and depends on the height of the cone L, the speed of movement of the cone V1and its taper, defined as:

.

Since V2greater than V1on the top of the exit cone, the water gushes, rising to some height H above sea level.

In the ideal case, the product of the mass of flowing water minthe height H is the expression value of the work produced by the kinetic energy of the fall cone mass mkat some depth h.

I.e. minĚH=mkĚh.

If the cone is continuously raised and lowered into the water with some velocity V1he will begin to lift the water, as any piston pump. To improve the efficiency of operation of the pump at the transition from the upper end of the cone 2 to the pipe supplied check valve 5, figure 1.

Structurally, the pump is a systems is fixed, 2, are fixed and pre-filled with water a number of containers 1. In a series of containers 1 in the first tank 1, the top edge is at the level of the ocean and the tank 1 is continuously filled with the movement of the tidal waves. In each of the tanks 1 are omitted mobile, not strictly associated with the body of the container 1 hollow cone 2 wide end down, and the top, narrow end with a vertical pipe, is at the level of the upstream capacity or slightly above it.

All cone 2 are rigidly connected with the bearing rod 3, which, in turn, relies on the pontoon float 4, reciprocating movement up and down under the influence of breaking waves, thus ensuring the movement of all cones 2 up and down relative to the fixed casing containers 1. When traffic cones 2 down, there is a gush of water from the narrow ends of the cones 2 and transfer it up in the next adjacent upstream capacity 1. Of the latter, the upper tank 1 water is gravity fed to the accumulating water tank, where it is dumped on the working body of the turbine.

The greatest effect of the latter is achieved when the height of the cone 2 from 1 to 3 meters and taper from 0.025 to 0.01.

In contrast to existing designs of pumps of similar purpose, the design is extremely simple, has not, as there is existing pumps, exactly the mating parts type cylinder-piston and sleeve-shaft.

Pump lifting water for marine tidal wave hydro containing pontoon float and a hollow truncated cone with wide bottom intake and top narrow feed part, which merges into a vertically directed pipe and rigidly attached to the pontoon to float with the possibility of reciprocating motion up and down under the influence of breaking waves, characterized in that the pump is equipped with a system of hollow truncated cones with the internal taper of from 0.025 to 0.01, which form a single rigid structure and fixed and pre-filled water containers, each of which is omitted mobile, not strictly associated with building capacity cone with the ability to divert water up in the next adjacent upstream capacity, and in the first capacitance upper edge is located at the water level with the possibility of constant filling movement of the tidal waves, and each of the cones is equipped with a separator non-return valve installed on the transition from cone to the pipe.
