WATER OUTLET FROM CHANNEL WITH STEEP SLOPE Russian patent published in 2015 - IPC E02B13/00 E02B8/02 

FIELD: construction.

SUBSTANCE: water outlet comprises the inlet 1 and transit 2 channels, associated with water intake gallery, having the water inlet opening in the upper part, covered with grid 11. Grid 11 also covers the V-shaped threshold 10, which separates the sediments before the bottom slot of gallery into coarse fractions. The side walls of the supply channel 1 are provided with guide elements with possibility of their displacement towards the threshold. Guide elements are designed with L-shaped vertical walls 13 with shelves 14, placed above the bottom of the supply channel 1. The lower edges of vertical walls are installed relative to the bottom of the inlet channel 1 with gap. Gallery is made with intake portal in the form of tube, the upper part of the case of which with oblique cut 6 is located above the slotted hole of the gallery. Due to the fact that the cross-section portal of tube with the inlet portion 5 is located slightly above the bottom of the chamber, the water flow to the discharge pipeline is increased, and flow regime through the portal into the transit channel 2 occurs without splashing and all sediments go down. In the presence of bending, the flow speed profile is more uniform in the pipeline, which reduces the tendency of flow separation from the inner curved wall and reduces the energy losses along the length of the pipeline, caused by the vortex turbulence. Pressure losses in the inlet portion at the presence of tubular portion, curved in three dimensions, as in the outlet portion of the pipeline, are reduced.

EFFECT: construction of water outlet as a whole provides its protection against the sediments, as well as in case of the absence of water inlet and simplification of the design at the increased discharge capacity, besides the length of the discharge pipeline is reduced respectively.
