The invention relates to the field of hydropower, and more exactly, to hydroelectric power plants.

A device for the energy of the river flow, comprising a housing in the form of floating icularly shaft, which is connected to the electricity generator (see the description of the invention along.with. The USSR 1513176, F 03 In 7/06 from 15.12.1988).

The specified device does not allow you to create a large torque on the shaft of the working body of the appearance of tipping water and wind loads on a floating basis, increasing the length of working blades, which essentially limits the use of the available kinetic energy of the natural water flow of the river to generate electricity.

A device for the energy of the river flow that is closest to the proposed invention, comprising a housing made in the form of betonirovannaa shore, and a fixed unit, the turbine of which is made with a vertical shaft and blades oriented in a vertical plane with the possibility of protrusion for the body housing and the shaft connected to the generator via a clutch (see Russian Federation patent 2020260 C1, IPC 7 F 03 7/00 from 30.09.1994).

A significant disadvantage of this device is the low coverage of the waters of the river as its width and length of the process of converting their kinetic energy into electrical energy, which limits the number of electroa the possible energy use only coastal waters, which is less than the energy of the waters of the river flowing close to the fairway. If this device does not provide any increase in pressure and velocity of water moving along its body compared to the natural, which limits the capacity of the power plant. In addition, the turbine operation in the hard drive causes rotation of water filling a niche in the housing, and significant turbulence in the flow in the working area of the blades, especially if they are extra long, which affects the hydrodynamic characteristics of the turbine and reduces the capacity of the power plant, which could be under the pressure of the water flowing along the body.

The objective of the proposed invention is to increase the coverage of river waters is the process of converting their kinetic energy into electrical energy to increase the production of electricity at the river.

The problem is solved by a device for the energy of the river flow, comprising a housing with a hydro turbine which is made with a vertical shaft and blades oriented in a vertical plane with the possibility of protrusion for the body housing, wherein according to the invention the casing as extended along reconnoitering the longitudinal axis of the dam, with the possibility of contact of the working surface of the blades with the flow of water during their rotation in the associated direction and the closing of the dam body in the opposite direction of rotation, and the shaft connected to the generator through a step-up gear.

It is desirable that the dam was made in the form of combing multiple dams along the river.

It is advisable that the blades were connected with the shaft of the hydraulic unit by means of a horizontal lever with vertical hinges and stops rotation of the blades with the ability of inflection when the direction of rotation towards the water and straightening when passing him the direction of rotation.

The essential features of the invention are performing body in the form of extended along the river dam with transverse openings; installing in the transverse openings of the units; the vertical shafts of the hydraulic units is offset relative to the longitudinal axis extended along the river dam, with the possibility of contact of the working surface of the blades with the flow of water during their rotation in the associated direction and the closing of the dam body in the opposite direction of rotation; shaft coupling unit generator through a step-up gear.

These essential characteristics are the distinguishing features of the invention and its sovokupnostei long jets of water along the river dams installed in her openings units, the working blade which stand for the body of the body of the dam. This provides increased speed, torque and power on the shafts of units that can be converted in high speed generators through a step-up gearboxes. Moreover, the execution of the body in the form of dams, extended along the river, with the placement of its openings generating units and allows placement in almost any area of the riverbed as its length and width allows for the most efficient use of the kinetic energy of the water flow of the river for conversion into electricity. This provides increased coverage of river waters is the process of converting their kinetic energy into electrical energy at high energy extraction water generating units to increase the production of electricity at the river.

Thus the performance of the dam in the form of combing multiple dams along the river, further enhances the dynamic parameters - pressure and speed of natural stream of water flowing along it, and increases the coverage of river waters is the process of converting their kinetic energy into electrical energy.

In addition, the connection of working blades with Valo the TEI with the possibility of inflection when the direction of rotation towards the water and straightening when passing him the direction of rotation reduces unproductive hydraulic resistance during the rotation of the turbine and allows you to use extra long blades, that increases the torque on the shaft of the hydraulic unit and the capacity of the power plant, further increasing the coverage of river waters is the process of converting their kinetic energy into electrical energy.

The invention is illustrated by drawings, which depict: Fig.1 is a schematic arrangement of hydroelectricity in the dam, front view in section; Fig.2 - hydraulic unit, top view.

In the drawings shows: riverside 1; dam of 2 with transverse openings 3; turbine unit working blades 4 on the horizontal arm 5 mounted on a vertical shaft 6, the hinges 7 and limiters 8 of rotation of the blades; seals 9, the radial bearings 10 and thrust bearings 11 on a vertical shaft; a multiplying gear 12 with a large pinion 13, associated with a vertical shaft turbine-generator units, and a small driven gear 14 connected to the shaft of the rotor of the generator 15, and the protective cover 16 that covers the generator and gearbox; the mounting sleeve 17.

The invention is as follows.

Along the river, preferably at the site of the fairway with the greatest rate of flow of water, building a dam of 2 reinforced concrete or metal structures with the transverse aperture of the horizontal levers 5, connected with a vertical shaft 6.

The vertical shafts 6 turbines offset relative to the longitudinal axis of the dam 2 with the possibility of contact is oriented in the vertical plane of the working surfaces of the blades 4 with a stream of water flowing along the dam, during their rotation in the associated direction and the closing of the dam body in the opposite direction of rotation.

Horizontal levers 5 are equipped with hinges 7 and limiters 8 of rotation of the blades 4 to extremes in their rotation in the direction towards the natural flow of water in the river and straightening when passing him the direction of rotation. Vertical shaft 6 is installed in the dam 2 on the radial bearings 10 and the thrust bearings 11, which are closed by seals 9, preventing ingress of water into the bearings 10 and 11.

The described device operates as follows. The natural flow of water in the river, flowing from the sides long dam 2, of the transverse openings 3 which are oriented in the vertical plane of the working blade 4, the condition of continuity of the jet increases the speed of its flow and concentrates its pressure along the entire hull dam 2. This water pressure rotates the working blade 4 with the horizontal levers 5 and connected to the vertical shaft 6 of the hydraulic unit. When this torque generated on a vertical shaft 6 unit working blades with 4 levers 5, through increasing gear 12 provides a high speed rotor shaft of the generator 15, to generate electricity.

Important to obtain a large torque on the shaft 6 of the unit is that the horizontal levers, submerged in water, while its rotation in the direction against the flow of the river almost have no water pressure, so as together with working blades 4, pivoting on the hinges 7 are closed by a body of the dam 2. This allows you to use extra long working blade 4.
