Problems solved by technology

[0003] However, the energy dissipation method of conventional stilling basins is generally that the rapid flow collides with the wall of the stilling basin to dissipate energy. However, the energy dissipation efficiency of stilling basins with large single and wide flow rates will be reduced, and the water flow out of the basin still contains a large amount of Residual energy, causing the downstream water flow to travel a long distance

Abstract

The invention provides an inner groove stilling pool structure for water flow energy dissipation, the inner groove stilling pool structure comprises a water inlet slope, a stilling pool main body section, a stilling pool tail sill, a back-flushing plate, a side wall and a Haimann, the water inlet slope is connected with an upstream flood discharge facility and is used for guiding water flow into a stilling pool, two inner grooves are formed in the bottom plates of the stilling pool main body section, the stilling pool tail sill and the Haimann, and the back-flushing plate is connected with the side wall. The depth of the stilling pool body section is symmetrically and gradually increased and then decreased from the two sides to the middle, two back-flushing plates are arranged on each inner groove, and a stilling pool tail ridge is arranged at the tail of the stilling pool body section. Energy dissipation is carried out through impact between water flow and a building and energy carried by the water flow, the energy dissipation efficiency of the stilling pool can be effectively improved, and the energy dissipation device has the advantages of being convenient to construct, low in cost, high in energy dissipation efficiency and the like.

Description

technical field [0001] The invention belongs to the field of flood discharge and energy dissipation facilities used in water conservancy and hydropower projects, in particular to an inner groove stilling pool structure used for water flow energy dissipation. Background technique [0002] In water conservancy and hydropower projects, flood discharge and energy dissipation is a prominent key technical problem in the project. Because the energy dissipation effect of stilling pools is relatively good, it is the most common. The stilling pool is a pool-shaped energy dissipation facility that can promote the generation of underflow hydraulic jumps downstream of the discharge structure, which can make the rapid flow of rapid discharge slow down. Generally, the energy dissipation effect of the stilling pool can reach 40%~70% %, is an effective energy dissipation facility, the most common in engineering. [0003] However, the energy dissipation method of the conventional stilling po...
