Combined energy dissipation wall for hydraulic engineering

Abstract

The invention belongs to the technical field of hydraulic engineering, and discloses a combined energy dissipation wall for hydraulic engineering. The combined energy dissipation wall for hydraulic engineering comprises a wall body, wherein a mounting groove is formed in the wall body, four auxiliary oil cylinders are fixedly mounted at the bottom of an inner cavity of the mounting groove, a base is fixedly mounted at the tops of the auxiliary oil cylinders, a main oil cylinder is fixedly mounted at the top of the base, and a limiting ring is fixedly mounted on the outer surface of the top of the main oil cylinder. According to the combined energy dissipation wall for hydraulic engineering, when oncoming impact water impacts a cambered surface wall through the cambered surface wall, the flowing direction of the oncoming impact water can be changed, the flowing direction of the oncoming impact water can be changed, the oncoming impact water flows downwards, the oncoming impact water directly impacts the inclined surface of a buffering plate, and the buffering plate moves downwards under pressure, so that a damping spring and a hydraulic mechanism which are lowered are driven to buffer water pressure, impact energy of water energy is partially converted into heat energy and elastic potential energy of the damping spring, then partial energy of water flow is converted, and the energy is counteracted.

[0002] Water conservancy energy dissipation is one of the problems that must be solved in the application of water conservancy projects. The usual energy dissipation method is to set up stilling pools, stilling sills, energy dissipation walls, etc. downstream of water retaining buildings to promote water flow within a limited range to generate water. The excess energy is consumed through the internal friction, aeration and impact of the water flow. The above method can also be used for the energy dissipation box structure of the pressure pipeline of the irrigation project and the water supply project, but these methods have certain disadvantages.

On the one hand, the energy that can be eliminated by using the hydraulic jump phenomenon is very limited. After the water flow on the front surface of the energy dissipation wall hits the performance wall, the mainstream will reflect or turn back in a certain direction. The stilling pool is long and the project volume is large. The cost is high, and at the same time, the water flow directly collides with the energy-dissipating wall, the interaction stress is large, and the damage to the water-facing surface of the energy-dissipating wall is serious, and it cannot fully apply the energy of the water flow itself.
