Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with specific embodiments. The purpose of the following words is to illustrate the present invention, rather than limit the protection scope of the present invention.

[0021] Such as figure 1 , figure 2 and image 3 As shown, the present invention can be implemented in the following manner. A multi-channel sill stilling pool capable of dispersing and dissipating energy includes a water flow inlet section 1 of the sill, a stilling pool body 2, and a stilling pool body located in sequence along the water flow direction. 2. The tail sill 3 and the apron 4 of the stilling pool at the tail end. The water flow inlet section 1 of the falling sill is provided with wide discharge holes 5 and narrow discharge holes 6 arranged in a staggered manner, and wide discharge holes 5 and narrow discharge holes. 6 is provided with a partition wall 7; the inside of the stilling pool body 2 is provided with ar...

Abstract

The invention relates to the technical field of water conservancy and hydropower building engineering, and discloses a multi-channel sill stilling pool for dispersion energy dissipation. The multi-channel sill stilling pool comprises a fall sill water flow inlet section, a stilling pool body, a stilling pool tail sill and a protector arranged in a water flowing direction in sequence; a wide flooding hole and a narrow flooding hole are staggered in the fall sill water flow inlet section; a separation wall is arranged between the wide flooding hole and the narrow flooding hole; an arc flow separation projection and multiple concrete piers are arranged in the stilling pool body in the water flowing direction in sequence at equal intervals; straight tooth patterns are uniformly distributed onthe surface of the flow separation projection in the peripheral direction; the section of each concrete pier is an antiparallelogram; and the protector is connected with the stilling pool tail sill tosolve the problems of higher water surface fluctuation, instable flowing state and damage of the internal structure of the stilling pool in energy dissipation of a traditional stilling pool.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower construction engineering, in particular to a multi-channel sill stilling pool capable of dispersing energy dissipation. Background technique [0002] The stilling pool promotes the generation of underflow hydraulic jump energy dissipation facilities downstream of the discharge structure. The stilling pool can quickly change the rapid flow of the discharge into a slow flow. Generally, the kinetic energy of the discharge flow can be eliminated by 40% to 70%, and it can be shortened. The length of the apron is an effective and economical energy dissipation facility; [0003] On the one hand, the first half of the stilling pool below the sill of the existing water flow inlet section forms a strong energy dissipation area, and most of the energy is concentrated in the first half to dissipate, so that the first half of the stilling pool forms a concentrated energy dissipation ar...
