Stilling pool auxiliary device capable of dissipating energy by utilizing self water power

Abstract

The invention provides a stilling pool auxiliary device capable of dissipating energy by utilizing self water power. The stilling pool auxiliary device is composed of an outer side wall, an inner sidewall, curved surface blade plates, a tail sill, upper shafts, lower shafts, plane blade plates, a bottom plate, lower grooves, a first columnar gear, a third columnar gear, a second columnar gear, ashort shaft, round holes and fixing columns. By means of the stilling pool auxiliary device capable of dissipating the energy by utilizing the self water power, the self water power of a torrential flow is completely utilized to drive the curved surface blade plates to rotate, the lower shafts are driven to rotate, and the plane blade plates above the lower shafts rotate in a counter-current mode,and water flow is forcedly pushed and blocked by using the water power and rotation in the counter-current mode of the plane blade plates above the lower shafts, so that the purpose of reducing the torrential flow energy to the maximum degree is achieved, and the energy dissipation effect is good. The stilling pool auxiliary device is particularly suitable for high water head water conservancy projects which are large in unit discharge and poor in downstream geological condition anti-erosion damage resistance.

[0002] China has abundant rivers and abundant rainfall, which are easy to develop water conservancy projects, such as the construction of overflow gravity dams, etc.; , it is often necessary to arrange energy dissipation work behind the overflow dam. Among the common energy dissipation work, the stilling basin is the most common because of its simple structure, convenient implementation, and relatively good energy dissipation effect; the stilling basin is a pool-shaped Energy-dissipating facilities that can promote the generation of underflow hydraulic jumps downstream of drainage structures can make the rapid discharge flow into a slow flow and shorten the length of the apron. It is an effective and economical energy-dissipating facility; The energy dissipation effect of the stilling pool is to consider how to set up the structure of the pool wall or the bottom surface of the pool to guide the water flow to better collide with the fixed structure such as the pool wall or the bottom surface of the pool to consume more water flow energy; When the water flow is large, the effect of energy dissipation is not obvious. Usually, it is necessary to set up a longer and larger stilling basin. These methods require high building strength for the water supply flow to hit the energy dissipation part, resulting in high implementation costs. The service life is short; Chinese patent CN 206267114 U is an auxiliary energy dissipation device for stilling pools, which is an alternative attempt, trying to let the water flow squeeze the force plate with the spring and drive the impeller to rotate to relieve the pressure of the water flow. Efficacy purpose, but its effect is extremely limited, and cannot effectively solve the problem later
