The invention relates to hydropower, in particular to constructions of devices for receiving compressed air and water supply from the river due to the energy of the hydraulic flow.Energy hydraulic flow of rivers and other run-of-river reservoirs are widely used in the national economy. For this purpose, the special at the consequently-mechanical energy. Known rotary water lift, driven hydraulic flow of the river containing water wheel and spiral pipe with the open end .The disadvantage of this device is that it only works in one mode of water supply. For this purpose, compressed air is necessary to create a water-air mixture. In addition, the device is not provided with a sufficiently tight connection end of rotary /scroll/ pipe fixed pipe cap. As a result of wear of the packing seal reliability and efficiency of the device decreases sharply.The closest technical solution, selected as a prototype, is the channel water installation including onshore well or borehole; samotechny line; the suction pipe, a vertically placed in the well or borehole; and water-lifting device in the form of pumps .A disadvantage of the known installation is that it is complex, provides opportunities for compressed air and use the energy of the fluid.The objective of the invention is to provide a simple and reliable setup, the current due to the energy hydraulic">The invention consists in the following. Onshore well or well completed to a depth exceeding the depth of the water in the river. In the flow of the river has the auxiliary power unit, for example water wheel driven by the energy of the specified thread. With the auxiliary power unit is kinematically connected to the compressor, equipped with intake air from the atmosphere and the discharge line of the air in the receiver. When this water-lifting device made in the form of airlift tip through a three-way valve connected with the discharge line of the air in the receiver. To simplify the design of the gravity line is made in the form of holes located on the side wall of the well or wells in contact with the soil below the water level in the river.In Fig. 1, 2 shows a device for producing compressed air and water supply from the river due to the energy of the hydraulic flow. It consists of a power unit /for example, a water wheel 14/, 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 15, is equipped with intake air 16 from the atmosphere. The compressor 15 is attached to a discharge line of the air in the receiver 4, Kotor 3 is equipped with a safety valve 20, as well as connecting device 1 with the crane control 2 air supply to the consumer. These elements together constitute the system, providing compressed air. The water supply system also includes an auxiliary power unit /water wheel 14/ C compressor 15 and additionally: onshore well 10 /well/ with airlift. The specified well completed to a depth exceeding the depth of the water in the river /bottom part of the river/ and equipped with a gravity line 12 is placed on the filter 13. When this type of line 12 provides the ability to fill the cavity of the well 10 to the water level in the river. Airlift consists of water-lifting pipe 8, the lower end of which is equipped with a nozzle 9 to the nozzle, and a filter 11 and loaded into the well 10 to the bottom part, the top is lowered into the tank 7, is equipped with a drain pipe 6 and the connecting device 4 with the valve control 5 water supply. This tip 9 through a three-way valve 18 is connected by discharge line of the air in the receiver 3. To simplify the design gravity flow line 12 may be made in the form of holes /in Fig. 2 they are shown by arrows/ placed on the side wall of the well 10, contacter what about the air and water supply. In the receive mode of the compressed air installation operates as follows. Three-way valve 18 is set to the "air": the compressor 15 is connected to the receiver 3, the air supply to the tip 9 of the nozzle is not performed. Using the controller 17 install the necessary pressure in order to set the rotational speed of the water wheel 14. When this hydraulic flow of the river acts on the blade wheel 14 and leads him into rotational motion. The compressor is kinematically associated with the specified wheel, sucks air through the intake 13 and forces it into the receiver 3 through the pressure regulator 17, a valve 18 and outlet valve 19. To discharge excess pressure generated by the compressor is provided a relief valve 20 is adjusted to the set pressure. Open the faucet control 2, and the air through the connecting device 1 enters pneumocyte /not shown/ consumer. For transfer of the facility to water supply valve 18 is set to the "Water": the compressor 15 is disconnected from the receiver 3, the air supply to the tip 9 of the nozzle. The compressed air in the form of bubbles, mixed with water, forms a column of water-air mixture. Air bubbles moving weredriven 7. Open the faucet control 5 and the water through the connecting device 4 enters the water /not shown/ consumer. The level of water in the well 10 is filled from the river by gravity line 12 or groundwater through openings in the side wall of the specified well /Fig. 2/ as a result of infiltration of river water through the bed. In case the overflow tank 7 water drained through the drain pipe 6. If necessary, carrying out repair and maintenance works or disable the installation of the water wheel 14 is removed from the stream.The proposed installation is simple, reliable and energy efficient. It can work in two modes: receive the compressed air and water supply. This is due to the fact that the installation includes two systems, one of which provides for receiving compressed air, the other the water supply. These systems have a common supply - water wheel kinematically associated with the compressor. The drive wheel carried by the energy of the hydraulic flow. The installation consists of simple and accessible structural elements.Sources of information
