The invention relates to hydropower and for installations that use the flow of water for electric power production.

It is known device for the generation of electricity using the kinetic energy of water containing hull boats with water conveyance channel impeller with curved blades mounted on the shafts, kinematically connected to the generator (see EN 2049924 C1 IPC6F03 7/00, 17/00, 1995).

A disadvantage of the known devices for generating electricity from the flow of water is the difficulty of fixing it in a certain place of water flow.

Known hydroelectric installation comprising a floating base, made in the form of a catamaran, between which is formed a channel is placed in the last conveyor with rollers and an endless belt with fixed on her blades, and a generator, kinematically connected with the shaft of the conveyor (SU 1474317 A1, IPC4F03 7/00, 1989).

The disadvantage of this setup is the difficulty of fixing it in a certain place of water flow.

Known hydroelectric installation, adopted for the prototype (see the patent of Russia №2258154 08.09.2003)containing a floating base, made in the form of a catamaran, between which is formed a channel is placed in the last botanocals attached to the outer surface of the blades and the generator, kinematically associated with the shaft of the water wheel, the diameter of the water wheel is smaller than its length, and the ends of the water-wheel are closed, the front profile of the blades of a water wheel made on a logarithmic spiral, the installation is equipped with a water pump, the drive of the electric generator is made in the form placed inside the water-wheel Overdrive gear of the wave transmission - multiplier, flexible wheel which is connected with the end of the water-wheel, the output shaft multiplier combined with the shaft of the water wheel and generator, which by increasing belt is connected with the water pump drive pulley belt transmission is mounted on the shaft of the generator, shafts, belt installed managed the clutch.

The disadvantage of this setup is the difficulty of incorporating it in a certain place of water flow.

The objective of the invention is to simplify the possibility of fixing a hydroelectric installation in a specific location of the water flow.

This task is achieved by the fact that in the hydroelectric installation comprising a floating base, made in the form of a catamaran, between which is formed a channel is placed in the last water wheel attached to the outer surface of the blades and generator, kinematically connected to the shaft of the water wheel. The walls of the channel formed by the hulls, made tapering, and the channel is symmetric about a plane passing through the axis of the water-wheel, in addition to the outer wall of the hull of a catamaran, which is an electric generator, is mounted at an angle to the flow detachable connection of the shield, on top of which there is fixed rope that secures the unit to the shore, and an electrical cable connecting the generator to the consumer, is attached freely to the rope.

The invention is illustrated graphic materials, where the drawing is given a top view schematic image hydroelectric installation.

Hydroelectric plant comprises a floating base, made in the form of a catamaran, between buildings 1 which is formed a channel is placed in the last water wheel 2 mounted on the outer surface of the blades 3 and the generator 4, kinematically connected with the shaft 5 of the water-wheel 2. To the outer wall of the catamaran hull 1, which is the generator 4, is mounted at an angle to the flow detachable connection with braces 6 shield 7, on the upper part of which is fixed ropes 8, connected to the cable 9, which hydroelectric installation is fastened to the shore, and an electric cable (not shown), with donaudy generator 4 with the electric power consumer, attached freely to the cable 9. Catamaran hull 1 are interconnected by means of the elements 10 are located at the top and bottom. The fastening of the shield 7 using braces 6 are detachable, in order, putting the shield 7 in another position (in the drawing is depicted by the dotted line), to carry out the generation of electricity, while on the left Bank of the water flow. In this case, the rotation of the water wheel 2 and the shaft of the generator 4 will be in the opposite direction and approval of the polarity of the incoming consumer DC you need to swap the wires of the electrical cable.

The hydroelectric plant works as follows. When lowering it into the water stream, is shown in the drawing by arrows, the last impact force on the shield 7, one component of which is directed perpendicular to the stream. Under the action of this force hydroelectric installation is removed from the shore to the place, due to the length of the cable 9. Due to this, it becomes possible to position it at the site of the river is fast flowing, which will greatly enhance the efficiency of the hydroelectric installation. In addition, due to the tapering shape of the channel located between the hulls 1, the water flow is accelerated and the effect on the blades 3 of the water-wheel 2, rotating it. The shaft El is regenerator 4, connected directly or via a gearbox (the latter not shown), with the shaft 5 of the water-wheel 2 rotates, the generator generates electricity, which is the cable attached to the free state directly to the cable 9, is delivered to the consumer.

The use of the claimed invention allows to simplify the fastening of the hydroelectric installation in a specific location of the water flow, which simplifies operation and improves efficiency.
