SWIMMING POOL Russian patent published in 2016 - IPC E04H4/00 

FIELD: construction; treatment plants.

SUBSTANCE: invention relates to construction of swimming pools with overflow water purification system. Said result is achieved by creating a swimming pool, which includes a sealed body, an the overflow trough located along its perimeter, divided into two compartments by partitions arranged in its corner parts, a floating overflow mat interacting with facing overflow chute side inclined grids, and filter material, laid around perimeter of bottom oblique lattice in form of foam blocks stacked close to each other and to reservoir wall by pool. Overflow trough formed in one piece as a profile of a sheet strip, upper part of which is curved in cross-section inside overflow trough is provided with perforations for overflow of water in overflow chute and connected hinged along top of a horizontal shelf with overhanging cantilevered above reservoir frame pool with rotation through 270 degrees. Lower part of sheet strip is bent radially outwards in cross section of overflow trough, is provided with perforations for returning treated water to tank and the basin rests bent upwards at a right angle to lower longitudinal shelf on wall of pool reservoir. In area of radius transition from upper part of profile to bottom there is a shelf inclined to reservoir, along which stacked longitudinal edge of overflow mat and pressed against an end edge of porous filter material, such as foam blocks stacked close to each other along inner radius of surface profile and necessary compression between bottom shelf and bent upward sloping shelf for radius in transition zone.

EFFECT: technical result is simplification of water treatment system and its maintenance.
