ALL-PURPOSE SELF-ACTING FLOOD CONTROL STRUCTURE Russian patent published in 2005 - IPC

FIELD: hydraulic structures, particularly flood control engineering structures.

SUBSTANCE: structure comprises body and sliding barrier walls displaceable in vertical direction and installed in the body. The barrier walls are connected to drive rods freely arranged on rotary pulleys and linked with guiding fixers. Guiding fixers are rigidly connected to sliding barrier walls. Supply and drainage tubes are built in the body. The body is installed along waterside or in flood-hazardous territory and is secured to developed and reinforced surface thereof or is embedded in upper part of bank slope or in flood control dam. The body includes box. Installed in box are protective barrier walls, which are arranged closely one to another in two continuous rows. The barrier walls have profiled side ends. Structure also has pool in which water tanks are arranged. Water tanks may be displaced in vertical direction by drive rods and have orifices in lids and bottoms thereof. Drainage tubes are provided with one-way check valve. Forks are connected to the first sides of barrier walls and may be secured so that the forks are displaced together with them in vertical direction. Cover plates secured along upper ends of protective barrier walls are used to cover the box from top thereof when barrier walls are arranged inside the box. Upper box walls have slots with T-shaped cross-sections in which sliders are arranged. The sliders are connected to forks through straps. The grooves mate in configuration with straps and cover plates.

EFFECT: increased reliability and automaticity.
