MOBILE WATER CIRCULATION CHANNEL Russian patent published in 2015 - IPC E04H4/12 A63B69/12 

FIELD: process engineering.

SUBSTANCE: invention relates to water mobile circulation channel consisting of swimming pool (1), return flow channel (3) and mid bottom (2) to separate pool (1) from channel (3). Return flow channel accommodates at least one transfer pump (4) and bends with vaned grates (5.1; 5.2; 5.3; 5.4) to deflect water flow. Streaming down side (12) of pump (4) has deflecting channel (7.1) composed by end edge (6) of mid bottom (2) and flute (8) with its inner sides surrounds end edge (6) of mid bottom (2). Cross-section of deflecting channel (7.1) diverges from bottom surface of mid bottom (2) to top surface thereof. Short diffuser (9) with several segment boards (11) is arranged at said streaming down side in the area of short diffuser flow, boards plane being directed parallel with the flow.

EFFECT: uniform distribution of flow rate, decreased sizes of circulation channel.
