The unit is designed to generate electricity, compressed air and water supply from the river due to the energy of the flow. The installation includes onshore wells equipped with water-lifting device and performed to a depth exceeding the depth of the water in the river, and with the possibility of providing a cavity filling with water until the water level in the river, set in the flow of the river water wheel driven by the energy of the specified stream, the compressor with the intake air from the atmosphere and the discharge line of the air in the receiver. Water-lifting device made in the form of pneumonias immersed in the well below the water level therein. Installation is additionally equipped with a turbo-generator to convert the energy of compressed air into electricity, while the compressor through the discharge line of the air in the specified receiver and additional valve control connected by the turbogenerator. On the discharge line of the air between the secondary valve control and turbine generator set pressure reducing valve that supports the constant pressure of air supplied into the cavity of the nozzle of the turbine. Installation design provides three modes: generating electrical energy with the tick, in particular, to devices for generating electricity, compressed air and water supply from the river due to water flow.

Energy hydraulic flow of rivers and other fluvial reservoirs wide use in the national economy. Known installation to use the energy of water flow "Tunguska", containing a moored floating body and impeller, kinematically associated with generators (1).

The disadvantage of this setup is that it does not provide the possibility of producing compressed air and water supply.

The closest technical solution, selected as a prototype, is a device for producing compressed air and water supply from the river due to the energy of the hydraulic flow. It includes onshore wells with water-lifting device, the water wheel, the compressor with the intake air from the atmosphere and the discharge line of the air in the receiver (2).

A disadvantage of the known installation is that it does not provide the possibility of generating electrical energy. In addition, for water supply requires the well, the depth of which should significantly exceed the height of rise of water, which complicates the installation.

The objective of the invention is gathogo air, electric power and water supply.

The invention consists in the following. Water-lifting device in the form of pneumonias immersed in a coastal basin or in the water flow. As a result, the water intake can be made directly from the stream, as well as from a well, the depth of which is considerably smaller than the height of rise of water. To convert the energy of compressed air into the electrical unit is additionally equipped with a turbo-generator. When the compressor through the discharge line of the air in the receiver and the additional valve control connected by the turbogenerator. Between the additional valve control and turbine generator set pressure reducing valve that supports the constant pressure of air supplied into the cavity of the nozzle of the turbine. This allows you to keep a given interval the frequency of rotation of the rotor of the generator. In General, the unit has a simple design and has improved performance characteristics.

The drawing shows gidroenergetichesky installation. It consists of a water wheel 1, is immersed in the flow of the river with the possibility of conversion of energy of the fluid into rotational motion kinematically associated with the compressor 2, the 8, which consistently placed the pressure regulator 4, three-way valve 19 and the pressure valve 18. When the receiver 8 is equipped with a safety valve 7, and the connecting device 5 with the valve 6 controls the air supply to the consumer. These elements together constitute the system, providing compressed air. The water supply system also includes a water wheel with 1 compressor 2 and additional onshore well 20 pneumonias 21. The well 20 is made to a depth sufficient to accommodate therein pneumonias 21 below the water level. On the side wall in contact with the ground water level in the river, there are openings /arrows/. At the discretion of the consumer, provided that the water level in the river is sufficient, pneumonias 21 may be immersed in the flow of water /not shown/. Thus pneumonias 21 through the valve 19 and the pressure regulator 4 is connected by the compressor 2 and is equipped with a pipeline to supply water to the tank 15, which is equipped with a drain pipe 12 and the connecting device 16 with the valve 17 controlling the supply of water to the consumer. To convert the energy of compressed air into the electrical unit is equipped turbogenerator structive elements 4, 19, 18/, and through the receiver and the valve control 9 connected by the turbine - nozzle 11. To maintain a constant pressure of air supplied into the cavity of the nozzle 11 between the valve 9 and the turbine /nozzle 11/ installed pressure reducing valve 10.

The system can operate in three modes: receive the compressed air, electricity and water supply. In the receive mode of the compressed air installation operates as follows. Three-way valve 19 is set to the "air", the valve 9 closes: compressor 2 is connected to the receiver 8, the air supply to pneumonias 21 and turbocharger /nozzle 11/ not made. The controller 4 stops the necessary pressure in order to set the rotational speed of the water wheel 1. When this hydraulic flow of the river affects the blades of the wheel 1 and leads him into rotational motion. The compressor 2, is kinematically associated with the specified wheel, sucks air through the intake 3 and forces it into the receiver 8 through the pressure regulator 4, the edge 19 and the discharge valve 18. To discharge excess pressure generated by the compressor 2, is provided a relief valve 7, is adjusted to the set pressure. Open the valve 6 and the air through prisoedenit electric power valve 6 is closed, and the valve 9 opened: compressor 2 through the regulator 4, the valve 19, the valve 18, the receiver 8, the edge 9 and the valve 10 provides pressurized air to the cavity of the nozzle 11, which sends it to the turbine 13. Under the action of a jet of compressed air turbine 13 is rotationally driven - rotates the rotor of the generator 14. As a result, the generator 14 produces an electrical current which is fed into the grid /not shown/ consumer. To improve the quality of electric power, the rotor speed of the generator 14 is supported in a given interval of the reducing valve 10, which provides a constant pressure of air supplied into the cavity of the nozzle 11 of the turbogenerator. For transfer of the facility to water supply faucet 19 is set to the "water": the compressor 2 is disconnected from the receiver 8 is dodeca air to pneumonias 21. The specified pneumonias can be equipped with suction and return valve float, and switchgear /not shown/. He is driven cyclically by compressed air supplied from the compressor 2, and the hydrostatic pressure of the surrounding water. This water rises in the pipe and is discharged into the tank 15. Opens the valve control 17 and the water che is almost not reduced, in the pit:20 is filled through openings in the side wall in the infiltration of river water through the bed. In case the overflow tank 15 water drained through the drain pipe 12. If necessary, carrying out repair and maintenance works or disable the installation of the water wheel 1 is removed from the stream.

The proposed installation is simple, reliable and energy efficient. It can operate in three modes: receive the compressed air, electricity and water supply. This is due to the fact that the installation includes three systems, one of which provides for receiving compressed air, the second - convert compressed air energy into electric energy, the third water supply. These systems have in common, the energy - water wheel kinematically associated with the compressor. The drive of the compressor is carried out by the energy of the hydraulic flow. The installation consists of simple and accessible structural elements.
