System for preventing overflows includes river or stream (l),(10),(18),(51) that should be diverted from its flow in accumulation (5),(14),(27),(54) using dam (2),(11),(19),(64) that includes water gate (3),(12),(35),(110),(67),(68),(73) and that water gate glides along guides (4),(13),(36),(37), (38),(69),(70),(72),(l 18),(119).Lowering and lifting of water gates is done by electro-motor (101), coupling (99),speed reducer (98),toothed wheel (100) and rack (102).If river is navigable it is used dam (19) which by rotating around axis (75) to support (24), enables shipping or dam (64) which by opening movable parts (65) and (66) enables shipping.Dam (19) by rotating to supports (25), (26),(126) directs water in different areas.Accumulation includes dam (8),(15),(28),(53) with water gates (120),(121),(122),(123) taht regulate return of water using channel (9),(16),(31),(52) in river or stream. |
