MULTIPLE-USE HYDRAULIC POWER FACILITY (VERSIONS) Russian patent published in 2008 - IPC E02B9/00 

FIELD: construction, water engineering.

SUBSTANCE: said utility invention relates to hydrotechnical and hydraulic power construction. The facility contains a hydraulic unit attached to a flexible blanket, a flexible apron, and the bed using channel anchors, and a water-retaining shell attached to the hydraulic unit using a rigid mounting assembly, and to the onshore anchoring supports with a cable system. In the first version, the cable system is equipped with additional longitudinal and transversal cables for the shaping of the water-retaining shell providing the calculated vertical compression of the flow and minimum head loss. In the second version, flexible plates are installed at the approach to the hydraulic unit for the provision of gradual lateral compression of the flow; the plates are secured to the rigid mounting assembly, bed slopes, and the flexible apron using anchors with tighteners providing pretensioning of the longitudinal cables. For the water-retaining shell stability and elimination of its vibrations, the facility is equipped with transversal stiffeners following the contour of the calculated cross section of the water-retaining shell and attached, along the perimeter, to the bed anchors with stay cables, the water-retaining shell from the headwater side, and the hydraulic unit using the rigid mounting assembly; and longitudinal stiffeners attached to the flexible plates, longitudinal cables, transversal stiffeners, and the water-retaining shell using flexible connections. In the third version, with small spans and stable bank slopes, the cable system is equipped with additional longitudinal cables for the shaping of the water-retaining shell providing the calculated vertical compression of the flow and minimum head loss. In the fourth version, for better stability of the structure, better tension of the longitudinal cables, and quick construction, extendable arms are installed along the upper and lower edges of the water-retaining shell; the arm ends are connected to the flexible plates. In the fifth version, the water-retaining shell consists of flexible strips or shapes attached to an elastic web from two sides, through which longitudinal cables pass for giving the shell a fantail shape; the flexible strips are installed at an angle to the flow to ensure the calculated shape of the water-retaining shell. In the sixth version, the water-retaining shell is designed as a closed fillable shell taking the calculated shape when filled with water or other filler through filling devices, and is secured with one longitudinal cable passing along its top. For fish protection, some versions have fish passes in the water-retaining shell, while the other versions have fishways at the hydraulic unit edges. For the protection of the hydraulic unit and the additional attachment of the cable system, a protection screen is installed.

EFFECT: construction of temporary water utilisation system for local power supply, irrigation, water supply, fish farming, and fire protection.
