FIELD: construction.
SUBSTANCE: device comprises a distributing channel 5, an intake pipe cap 2 and a drain pipe. The device comprises a diffuser from composite pipe sections of a conic section, designed in the form of a lock 1. The lock 1 is fixed by means of a hinge on the edge of the channel 5, having a slewing gear in the form of a control wheel 6 with a stopper. The inlet end of the diffuser 1 has the pipe cap 2, the cut angle of which is equal to 6…9° to the bottom of the channel 5. The outlet end of the diffuser 1 is joined with the pipe section 3 of a constant cross section with a flexible hose 4. The curvature radius along the axis of the diffuser is Ro=1.25din, where din - diameter of the intake pipe cap. Operational reliability under conditions of a variable water level in the channel is increased and an effective protection of the lock against wastes and sediments is provided.
EFFECT: improved operational reliability of the device by providing water extraction from different levels.
