Energy dissipation type steep slope water delivery tank Technical Field The utility model relates to the technical field of hydraulic engineering, in particular to an energy dissipation type steep slope water delivery tank. Background At present, abrupt slope water delivery is widely adopted as a common form in mountain water conservancy projects, farm irrigation and hydropower station water diversion systems because the abrupt slope water delivery is realized by means of height differences, and the abrupt slope water delivery has the characteristics of low construction cost, high operation efficiency and the like. Under the action of gravity, water flow rapidly slides down along a channel with a large gradient, and long-distance water quantity allocation can be rapidly completed. However, along with the elevation of the water delivery height difference and the flow velocity, the high-energy water flow is very easy to impact the downstream structure, so that potential safety hazards such as scouring, erosion and even structural instability are brought. For the above related matters, the basic structure of the existing steep slope water delivery tank is usually a concrete or steel structure water tank with a certain inclination angle, water flows from a high place along the tank body in an accelerating way, a conventional water outlet or a water drop platform is arranged at the outlet of the tank body, and the water flow is led to enter a downstream channel or a buffer zone. In some applications, the outlet is provided with a simple energy dissipation structure, such as a protrusion or a stepped profile, to attenuate some of the kinetic energy. However, the existing energy dissipation type steep slope water conveying tank still has a plurality of limitations in specific use. Firstly, traditional energy dissipation structure is mostly single form, if only sets up drop bank or simple stilling pool, can't fully adapt to complicated changeable high flow rate environment, and energy dissipation efficiency is not enough, easily appears the low reaches and erodes the destruction. Secondly, the internal structure of the stilling pool is often arranged coarsely, targeted optimization is not carried out, effective turbulence cannot be achieved, and local energy concentration is caused. Thirdly, the response of the water flow regulating system is slow, the control mode is mostly mechanical and manual, and the water flow regulating system is not suitable for application scenes with frequent fluctuation of flow.
