The invention relates to hydraulic and hydroelectric construction and can be used in the construction wodoodporne structures, including in emergency situations, to create a small mobile power stations.

A device of the dam, including flexible shell made across the width of the watercourse along the upper edges connected by cable systems, and the lower edge is stationary.

Reasons that prevent obtaining the desired technical result, are cumbersome and greater precision in its construction (USSR Author's certificate No. 943376, CL EV 7/20,1976).

A device downstream of the dam, including flexible open wodoodporne and closed water shell, downcast and the apron, the holes in the middle part of the shell (USSR Author's certificate No. 1708009, CL EV 7/20,1991).

The obstacles to obtaining the required technical result is the complexity in operation and no device turbines use the kinetic energy of the flow.

Closest technical solution is a portable submersible unit with cross-flow turbine (brochure of the firm "Energy Alliance", "Portable submersible unit with cross-flow turbine", 2002)

The reason, which is adequate to obtain the desired technical result is the impossibility of its use with shallow stream.

Closest technical solution is a mild dam is attached from the side of the downstream pipeline. (B. I. Sergeev, M. Stepanov, Shumakov B.B. Soft design is a new type of hydraulic structures. - M.: Kolos, 1971).

The obstacles to obtaining the required technical result is the complexity of installation, no element for utilization of the energy flow, the cross-sectional shape of the pipeline that do not provide optimal conditions approach flow to the unit.

The proposed solution will allow you to create a temporary water management node with the decision of the local energy supply, irrigation, water supply, fish farming, and provide for containment of a wildfire.

The closest technical solution is a mobile hydropower facility sleeve-type on the basis of membrane suspension dam with an external nozzle with control valve, dismountable joints, flexible hose with a configuration that makes it possible to minimize the loss of energy of the flow to the hydraulic unit and supported in the project at the expense of the filled shell through the pipe with a valve attached to the outer nozzle (Patent RF 2413050. Mobile hydroenergetics the e construction of a sleeve-type, CL EV 7/20, publ. 27.02.2011,).

The obstacles to obtaining the required technical result is the negative impact of flow on a flexible hose downstream structures in the flow over the crest wodoodporne shell, causing it to vibrate and reduce the time of trouble-free operation.

This technical result is achieved by creating a mobile micro hydro sleeve-type with cross-flow turbine, in which the distinguishing features are the presence of symmetric cut wodoodporne shell relative to the sleeve, thereby providing flow through wodoodporne shell only on the coastal areas of the junctions without affecting the flexible sleeve, also on top of the unit has a regulator unit, the unit is set to fill the shell, which allows to avoid the effects of water flow from the downstream of the unit.

This construction operates as follows. The structure is decomposed into a Bank, then wodoodporne shell with cutouts 4 with attached guys-guy 2, guy rebounds 3, downcast 18 and apron 17 is installed in the watercourse. When the flow of water downcast 18, fortified channel anchors 13 connected fastener Assembly with wodoodporne shell with cutouts 4, is pressed to the bottom of the watercourse due to the hydrostatic pressure created when the water level upstream, while downstream to the outer nozzle with adjustable valve 5 by means of rashemen the th connection 6 is attached a flexible hose 7 through line with the fill valve casing 14, mounted on the apron 17 before mounting the flexible hose 7. After filling the filled shell 14 with water on the outside of nozzle with adjustable valve 5 is provided a supply of water to the flexible hose 7, attached to the guide unit 8 unit 9 after installation wodoodporne shell with openings 4, and due to the flow regulator and servo motor provides the most optimal mode of operation of the unit. Then through the guide apparatus flows into the hydraulic unit 9, where the utilization of energy flow at the outlet from which water is supplied to the apron 17 and wodoodporne shell 4 and the sleeve 7 protects from floating debris litter retaining device 16. When the flow over the crest of the shell is provided with cutouts 4 reset flow only from the coastal abutting himself flexible hose 7 is not experiencing impacts from iridescent layer of water.

If necessary, this structure can be transferred to another similar target and be used multiple times during an emergency.
