WATER FLOW ENERGY DISSIPATOR Russian patent published in 2015 - IPC E02B8/06 

FIELD: construction.

SUBSTANCE: water flow energy dissipator includes water line 1, pressure pipelines 2 provided with swirling devices 3. Pipelines 2 are connected with outlet sections to closed housing 5 in the form of a chamber towards each other. Mixing chamber 6 of a square cross-section is located under housing 5. Baffle wall 7 of chamber 6 has concave pressure face 8 made so that it faces upwards and to the side of outlet sections of pipelines. At the mixing chamber outlet point, a discharge channel is covered with plate 16 connected to partition wall 11. Baffle wall 7 of chamber 6 has inclined hole 9 attaching chamber 6 to discharge channel 10 and directed towards partition wall 11. Partition wall 11 is intended for changing the direction of the flow leaving outlet hole 15 of mixing chamber 6 to discharge channel 10, where jet flow from inclined hole 9 is connected to one common flow, which reduces bottom velocities after partition wall 11. Closed housing 5 is also provided with pipe 13 with gate valve 14 for pressure supply of air or atmosphere.

EFFECT: improving efficiency and reliability of dissipation of kinetic energy of the separated and again joint flow; high protection degree of a discharge channel against dynamic effects provided by air accumulations opening to the lower pool, which improves reliability of a water flow energy dissipator, reduces length of the closed section of the discharge channel and excludes the need of a well device for the lower pool of the channel.
