the invention relates to the field of marine engineering and is designed to convert the energy of ocean currents (tides) into electrical energy for the preservation of life of fishes.

Known floating tidal power plant, comprising a vertically floating column with inclined bearing beam, one end of which is hinged to the column, and the other to the bottom plate, a column mounted for rotation around the vertical axis of the bottom plate and the height has several bilateral horizontal consoles, the ends of which are mounted generators with open blades (rotors), the rotation of the column allows you to operate the power plant at high tide and ebb, due to the automatic installation of rotors to meet flow into the sea (Chumakov. A burst of energy. The "Vokrug Sveta"magazine, №3 (2822) March 2009, p.78-82).

The disadvantages are the counterpart complex and unstable design of the column during the storm and bulky low-speed open rotor, which can injure the fish.

Closest to the proposed invention is a floating wave power plant, including several floating vertical cylindrical shells, each of which housed the generators working bodies which are placed in vertical water drainage is shirts, fixed to the side surface of the shell, the lower end of which by means of a system of ropes and anchors attached to the bottom of the sea (patent NO, NO 151479, F03B 13/12, publ. 17.04.1985).

The lack of floating wave power plant is that in the process of passage through the working bodies of the generators fish gets injured and dying.

The technical result, which is aimed by the invention consists in the improved construction of the power plant to improve its efficiency for fish protection, by eliminating their passage through the working bodies of the generators.

To achieve the technical result in floating tidal power plant, which includes more than two floating vertical cylindrical shells, generators, water intake and discharge pipes, a system of ropes and anchors, floating vertical cylindrical shell mounted with a gap between adjacent floating vertical cylindrical shells on the sea shelf along the longitudinal line that is perpendicular to the direction of the tide, floating vertical cylindrical shell are connected by a rope strung with him dampers, each floating vertical cylindrical shell provided with a water intake chamber, concentrically placed in the center of this shell, which is placed zakruchivali the stream output pipes water pipes, a perforated distributor of flow, the Central perforated riser ribotta pipe and inlet pipes drainage pipes and output pipes rebootottawa and drainage pipes placed in the gap between adjacent floating vertical cylindrical shells.

In addition, the inventive solution has the optional features that characterize its special cases, namely:

the absorber is made in the form of a package of used tires;

- perforated distributor of flow is made in the form of a truncated cone with the top open and the bottom base, a closed wall;

Central perforated riser is made in the form of a tube with an open bottom hole and the top hole is connected with ribotta pipe.

The distinguishing characteristics of the proposed device from the prototype that is closest to it, is that floating vertical cylindrical shell mounted with a gap between adjacent floating vertical cylindrical shells on the sea shelf along the longitudinal line perpendicular to the direction of the tide, floating vertical cylindrical shell are connected by a rope strung with him dampers, each floating vertical cylindrical shell provided with a water intake chamber, concentrically placed in General the requirements of this shell, hosting twisting stream output pipes water pipes, perforated distributor of flow, the Central perforated riser ribotta pipe and the inlet pipe branch pipe, the output pipe rebootottawa and drainage pipes placed in the gap between adjacent floating vertical cylindrical shells.

Due to the presence of these characteristics, the use of this device allows to increase the effectiveness of protection of fish, by eliminating their passage through the working bodies of the generators.

The proposed floating tidal power plant is illustrated in the drawings, figure 1-3.

Figure 1 shows in plan floating tidal power plant.

Figure 2 is a longitudinal section of a floating vertical cylindrical shell.

Figure 3 - cross section of a floating vertical cylindrical shell.

Floating tidal power plant comprises a floating vertical cylindrical shell 1 adjacent of which are mounted with a gap of 2 along the longitudinal line 3, perpendicular to the direction of the tide 4. Adjacent floating vertical cylindrical shell 1 is connected at the top and bottom longitudinal line 3 cables 5, which is threaded dampers 6, made in the form of service used car Chi is. On a transverse line 7, on both sides of the floating vertical cylindrical shell 1 in the middle of their parts are attached to the cables 8 are connected to the anchors 9. In floating vertical cylindrical shell 1 is concentrically placed cameras: water intake 10 and 11 dry. Water-intake chamber 10 is divided by a partition 12 into sections, for example one or more (figure 2). In each section of the water intake chamber 10 posted by weekend nozzles 13 installed tangentially to the swirl flow; perforated distributor stream 14 made in the form of a truncated cone with an open top and a closed wall 15 of the lower base; a Central perforated riser 16, made in the form of a tube with an open bottom hole 17, and the top connected with ribotta pipe 18; the inlet 19 of the outlet pipe 20. Dry chamber 11 posted by intake pipe 21, the inlet openings 22 which are placed on both sides of the floating vertical cylindrical shell 1 by a transverse line 7; generators 23, working bodies are placed in bypass pipes 20. Outlet openings 24 rebootottawa pipe 18 and the outlet port 25 of the branch pipe 20 is placed on both sides of the floating vertical cylindrical shell 1 along the longitudinal lines 3 and communicated with the sea in the gap 2, where is low pressure, due to the higher flow velocities. Pun is Tierno line 26 shows the position of the floating vertical cylindrical shell 1 at the maximum water level in the sea.

Work floating tidal power plant is as follows.

Work floating tidal power plant is carried out at high tide and low tide, and the only difference is that the sea water when the tide comes right at the inlet 22 of the intake pipe 21, and at low tide on the left. Sea water flows around floating vertical cylindrical shell 1, mounted on a longitudinal line 3, and passes through the gap 2 between adjacent floating vertical cylindrical shells 1. Gap 2 is formed by cables 5 (top and bottom), on which are strung the dampers 6. Floating vertical cylindrical shell 1 is held on a longitudinal line 3 by means of cables 8 and anchor 9. At the maximum water level floating vertical cylindrical shell 1 surface in the position shown by the dotted line 26 (figure 2).

Consider the operation of the plant at high tide 4. When the wrapping thread floating vertical cylindrical shell 1 by a transverse line 7 at the entrance of the stream into the inlet 22 is increased pressure, but when the flow from the outlet 25 of the bypass pipe 20 in the gap 2 is the reduced pressure due to the higher speeds. Under the influence of this pressure drop occurs during the flow in the outlet 20 and the waters of the intake pipes 21.

The flow of fish passing through the outlet 13, clockwise to the receiving chamber 10, which is divided by a partition 12 into sections (one or more). Since the density of fish is less than the density of water, the fish under the influence of her body centripetal forces will move to the center of the receiving chamber 10 and to deal with part of the flow (flow of rebooted not more than 5% of the flow rate of intake) through the Central holes of the perforated riser 16 through the open bottom of the hole 17 and further ribotta pipe 18 bypassing the outlet 24 back into the sea. In ribotta pipe 18 occurs over due to the pressure drop in the intake chamber 10 and in the sea (gap 2).

The main stream without fish passes through the holes of the perforated distributor of thread 14, the bottom of which is closed by a wall 15, and is supplied to the inlet pipe 19 of the outlet tubes 20, passes to the working body of the generator 23 installed in the dry chamber 11, rotates it, and then bypassing the outlet port 25 goes to sea (gap 2). Thus, the generator 23 generates electric power.

At low tide the sea water intake is through the inlet openings 22 located on the left side, and repeat the process.

The introduction of the proposed tidal power plant allows to obtain electricity is th energy from sea currents and to operate the plant without damaging the fish, keeping her alive.
