Abstract

The invention relates to hydraulic structures and can be used to quench the kinetic energy of the flow in the end part of the spillway. The purpose of the invention is to increase the efficiency of the flow energy quenching The water flow energy damper includes a water well bucket made in the end part of the catchment and a flat flow divider installed in the well bucket above the spillway surface. In the lower part of the bucket well, a vertical chamber is located above the flow divider, communicating with the cavity formed by the overflow surface and the flow divider. The chamber wall facing the water outlet construction is made along the width of a ladle-well with horizontal slits and canopies. The slits are located in the height of the camera Rus, and over each slot outside the camera is installed a visor. 2 Il. with o (Lu yu eo oo

Description

The invention relates to hydraulic structures and can be used to quench the excess kinetic energy of the water flow when exiting the spillway to the nilchii bay.

The aim of the invention is to increase the efficiency of the quenching of energy flow.

FIG. 1 shows a water flow absorber, a longitudinal section in FIG. 2 - the same plan.

The water flow energy absorber includes a water-bucket-well 1, made in the end part 2 of the water-discharge box 3, a separator

4 streams installed in the sump 1 above the overflow surface

5 a water disposal facility 3, and a vertical chamber 6 located in the lower part of the ladle-bucket 1 above the flow divider 4 and communicated

with a cavity 7 formed by the spillway surface 5 of the outlet structure 3 and the flow divider 4. At ZT0M, the wall 8 of the chamber 6 ,, facing the water outlet construction 3, is made with horizontal slits 9 and goat 10, and the slits 9 are made across the width of the bucket 1. And are located in ruts 6 of the height of chamber 6, above each slot 9 outside the chamber 6 hoses are installed 10. The flow divider 4 is made flat1 and is located parallel to the overflow surface 5 of the end part 2 of the outlet 3,

The water flow energy absorber works as follows.

The flow of water flowing through the spillway surface 5 of the spillway structure 3 is divided into two parts by separator 4, the lower part of which flows under separator 4 of Flow into cavity 7 and then into vertical chamber 6, and the upper part of flow continues through separator 4 well flow

1e where, hitting the wall 8, loses some of its energy.

The lower part of the flow is rotated in the chamber 6 by 180, which provides a significant decrease in the flow rate, and then the passage through the slots 9 in the wall 8 of the chamber 6 collides in the bucket-well 1 with the opposite upper part of the flow. efficient and smooth quenching of water flow energy. Peaks 10, creating additional resistance to the flow, contribute to the quenching of energy and the direction of flow, as well as prevent splashing. At the outlet of the quencher, the water flow smoothly spreads in the downstream across its width.
