| Patent Request 1. System that uses sea waves for accumulation of the water on certain height in order to use it for production of the electricity and upon need, for desalination, is characterised with containing two or three functionally connected units; the first one made of working float (1) with inside cylinder (3) with firm link (5) is connected to sealing piston (4) that could be moved up and down along the compression cylinder (2) secured by stabilator (30) on which are one-way inlet valves (6) or (7) or both and one-way outlet valve (8) positioned on the entry of buoyancy tube (9) which could lead directly to accumulation tank (10) and from its lowest point leads vertical tube (26) that has at the opening a regulator of the flow (29) and at the bottom, a turbine (27) connected with a generator (28). If this system is used for desalination of the water than the buoyancy tube (9) has a fork in a way that lower level accommodates a tube (12) into evaporator (11) where water comes to the certain level up to the point of closing this tube (12) in a way that water flows to slightly higher prong (13) and connects with a flow cooler (24) and flows out in the place (25) into accumulation tank (10) cooling the tube in a process (21) that gets from the top of the evaporator (11) a collected aerated water, and condensed, desalinated water goes down the tube (23). 2.

Technical field concerning the invention
The invention belongs to the area of Production, transformation, and distribution of the electricity as well as to the area of Methods or facilities for extraction or collection of the drinking or running water. According to International Patent Qualification (IPQ) references are E02B, E03B and F03B.
Technical problems
The invention solves the construction problem of the system that is used for production of the electricity and at the same time and upon need, for desalination of the sea and ocean water.
Technical conditions
The system for the use of sea waves for production of the electricity, so far, has been realised in different ways. All of these solutions are mostly based on direct transformation of the mechanical energy of the waves into electricity. It has many deficiencies since the sea waves impact is periodical and the electricity with its practical application demands continuity. Also, electricity is needed when the waves are absent, so the accumulation system that solves the problem of continual production of electricity from the sea waves, in certain period of time or permanently, would be a solution for mentioned problem.
Presentation of the invention essence
The system consists of the working float connected with sealing piston that could move up and down along the working cylinder with one-way valves, inlet and outlet, for the purpose of retracting and pushing the water, pipes that lead the pushed water to the certain height, an accumulation tank for the raised water, a vertical tube that leads the water from the tank to the turbine blades connected with the generator, and upon need, to the tank for the evaporation of the sea water at the particular height from which.is possible to direct previously condensed water, under pressure, to the consumer or for the further processing.

The picture shows System that uses sea waves for accumulation of the water on certain height in orderto use it for production of the electricity and upon need, for desalination by evaporation and it consists of working float (1) moving under the impact of the sea waves along a compression cylinder (2) in which is a sealing piston (4) linked with a firm assembly (5) connected with inner cylinder (3) that goes through the middle of the float (1) and should have the greatest mass of the float (1) distributed around. On the compression cylinder (2) should be one-way inlet valves (6) or (7) or both; the water comes through them into the cylinder when the wave lifts the float (1) and one-way outlet valve (8) after the passing of the wave, compresses the water with weight of the float (1) and sealing piston (4). One-way valve (8) opens the passage for the constricted water into buoyancy tube (9) which could lead directly into the tank (10) if the aim is the accumulation for production of the electricity by water collapsing from the certain height, or it could be sent by a prong (12) into an evaporator (11) filling it up to certain height with a help of a self-closure system that could be solved in different well known ways, and here, it is presented with elements 14, 15, 16, 17 and 31; floating porous plate (17) should be balanced by floats (16) so it is kept afloat under the water level in the evaporator and it is used for additional heating of the water which, however, gets larger amount of the heath from the evaporator sphere (11). This porous plate (17) could be linked with a tube (20) shutter (19) that serves to lead collected salt or highly concentrated salty water for storing or further processing. This could be the result, but it mustn't be, since this opening could be solved automatically with remote control or mechanically as with tube (26) where the water from the tank (10) down flaws onto the turbine (27). There is a slot (14) on the part of the tube (12) which is inside of the evaporator (11) and contains a wedge (15) on the rim of the round porous plate (17) that is kept afloat with a float (16) made of cork, styrofoam, hollow pipe or similar light weight material. The magnets (31) that hold the wedges (15) are placed opposite to keep the balance. The process of opening and closing of the tube (12) is listed only as possible considering the existence of many known solutions and therefore is not a subject of this patent protection. The important fact is that when the tube (12) gets closed with reached level of the water in the evaporator, the compressed water would continue flow through the tube prong (13) which is on the higher level, so it opens afterwards. From the tube prong (13) water goes into flow cooler (24) that cools the steam in the condensation tube (21) leading from the top of the evaporator (11) wrapped in isolation (22) all the way to flow cooler (24). Cooled steam in the form of condensed, desalinated water is directed for the use or further processing, under the pressure, down the tube (23) and the water from the flow cooler gets out in the place (25) to the tank (10). While the process is taking place in the evaporator (11) the tank (10) is filled up from the flow cooler (24). If there is no unit for desalination by evaporation (11) or if one phase of this system is omitted, the water from the tube (9) would go directly to the tank (10). The bottom of the tank (10) shaped as a funnel extends to the vertical tube (26). Accumulated water, via the system (29) is let to flow in controlled amount with free fall down the vertical tube (26), it drops onto the turbine blades (27) and its turning starts the generator (28).
In order to stabilise working float (1) against progressive movement of the waves, the firm link with the sea bottom is used in a form of stabilator (30). It is possible to use the prongs (32) placed symmetrically on the envelope (36) that also contains floats (35) with rings (33) at their ends. Through these rings, pass the stabilising pillars (34) in a way of allowing free movement of the working float, up and down along the pillars (34).
Protection of the working float (1) from the progressive movement of the sea waves could be also secured with a protective rampart (37) made of cylinder halves whose ends overlap along the axis. Alternatively it can be done (not shown here) by placing the system for transformation of progressive sea waves into electricity under the working float (1).
Evaporation tank (11) with its stabilising system (30) as well as accumulation tank (10), could be in the sea but also on the land, especially if the shore line is raised up enough to enable building of the accumulation tank (10), for example, in a form of a sunken pool with exhaust vertical tube (26) whose ends lead to the sea level.
