The application relates to a river bend anti-scouring damage device, and belongs to the technical field of river anti-scouring. The river bend anti-scouring damage device comprises a concave bank slope, a tooth wall is arranged on the concave bank slope, the tooth wall comprises a plurality of anti-scouring wall bodies arranged on the concave bank slope, the plurality of anti-scouring wall bodies are sequentially and spacedly arranged along the vertical direction, and the distance from one side of the anti-scouring wall body close to the convex bank slope to the other side of the anti-scouring wall body close to the concave bank slope increases sequentially from top to bottom. The application has the advantages of improving the anti-scouring effect of the concave bank to a certain extent.

A slope section differential energy dissipation structure belongs to the technical field of hydraulic engineering structures and is characterized in that a bottom plate and at least one group of stilling piers are sequentially arranged on a slope section at the upstream of a stilling pool of a release structure from bottom to top. The stilling piers are arranged in a plum blossom shape, and the whole stilling piers are in a barb body shape perpendicular to the water flow direction. The baffle piers enable water flow to turn and collide with each other behind the piers, so that turbulent fluctuation of the water flow is increased, the water flow is divided into a plurality of small water strands, flow velocity distribution is adjusted, the water flow is discharged group by group, friction with the water flow is increased, roughness of a slope section is increased, energy is dissipated along a flow space, energy dissipation efficiency is improved, and downstream scouring of hydraulic structures such as gate dams and the like can be improved. The scouring damage of discharged water flow to the stilling pool, the apron and the riverbed is relieved, the efficient energy dissipation effect is achieved, and the requirements of engineering safety and the like are met.

The present application relates to the technical fields of industrial fluid control and valve automation, in particular to a stop valve multi-target collaborative control optimization system based on industrial data processing, comprising a multi-dimensional data acquisition step: a multi-dimensional data acquisition center calls real-time operation parameters of the stop valve; a flow resistance characteristic coupling analysis step: a fluid state observation unit calculates the current flow coefficient and the transient pressure difference value based on the parameters; a risk discrimination and decision step: a working condition risk assessment unit quantifies the water hammer and cavitation indexes, obtains a comprehensive risk evaluation value by weighting, and outputs a smooth control or ultra-fast response signal accordingly; a trajectory planning step: a trajectory planning unit respectively generates a nonlinear damping velocity curve or a linear step velocity curve according to the signal type; a flexible execution step: a flexible execution unit drives the stop valve to act, and monitors the closing contact state to realize the switching of the velocity and torque control modes; the present application solves the problem that the traditional control ignores the fluid dynamics risk, and prolongs the service life of the equipment.
