Stilling pool with continuous incident angle

Abstract

The invention discloses a stilling pool with a continuous incident angle. The stilling pool with the continuous incident angleconsists of an inflow section, a stilling pool, and a tail sill, wherein the inflow section, the stilling pool, and the tail sill are sequentially arrangedin the water flow direction, diffuser sills are arranged on a bottom slope of the tail end of the inflow section, and the two diffuser sills are symmetrically arranged on the left and right sides of the inflow section; the upper surface of each of the diffuser sills is a circular arc surface in the direction of the water flow, the upper surface of each of the diffuser sills is in smooth engagement and transition with the bottom slope, and the height from the corresponding bottom slopeincreases gradually in the water flow direction; the lower surface of each of the diffuser sills is fixedly connected with the corresponding bottom slope, one side wall of each of the diffuser sills is fixedly connected with the side wall of the corresponding inflow section, the width of each of the diffuser sills in the direction of the water flow graduallydecreasesin a linear mode until decreases to zero at the tail end of the inflow section, thus a flared groove is formed in the middle of the tail end of the inflow section. According to the stilling pool with the continuous incident angle, the mixing effect of water body in the stilling pool and the energy dissipation efficiency of the stilling poolcan be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a stilling pool with continuous incident angles. Background technique [0002] As a traditional form of energy dissipation, underflow energy dissipation is widely used in engineering because of its outstanding advantages such as simple structure, high energy dissipation efficiency, stable flow state, and weak atomization. Applications. [0003] Traditional stilling pool structures such as figure 1 (top view) and figure 2 As shown in the (front view), the stilling pool is composed of the pool itself 2 and the tail sill 3 of the stilling pool. maintain a single angle of incidence α (Incident form such as image 3 As shown), the high-velocity water flow is mainly concentrated on the bottom plate of the stilling tank, and the water body in the pool is not fully utilized for energy dissipation. There is room for further improvemen...

Problems solved by technology

However, the stilling pool of this patent also has only one angle of incidence at the head of the pool, and only uses a part of the water body in the stilling pool for energy dissipation; at the same time, compared with the conventional hurdle, it is nothing more than changing the energy dissipation water body from the water flow at the bottom of the pool to slightly A part of the water body far away from the bottom of the pool does not make full use of the water body in the pool for energy dissipation
