Intelligent adjusting and optimizing flow guiding device for river channel confluence flow field and application
The invention discloses an intelligent adjusting and optimizing flow guiding device for a river channel confluence flow field. The intelligent adjusting and optimizing flow guiding device for the river channel confluence flow field comprises a flow guiding device and a fixed rod shaft installed at one end of the flow guiding device, wherein the flow guiding device swings with the fixed rod shaft as an axis. When the flow of river channels ways on the two sides changes, the impact force of water flow on the two sides of the flow guiding device also changes, so that the flow guiding device rotates towards the side where the flow and the flow velocity are reduced, and finally tends to be balanced again under the action of combined external force, and therefore, the cross-sectional area of an outlet of the river channel on the side where the flow is increased is also increased; meanwhile, the cross-sectional area of the outlet on the other side where the flow is reduced is also reduced, and the flow velocities of the outlets on the two sides tend to be equal or equivalent, so that the flow guiding device can achieve the purpose that the confluence flow state at the junction of the two river channels is more stable even if the incoming flow ratio of the two river channels is changed.
本发明公开了一种河道汇流流场智能调节优化导流装置，包括导流器、安装在导流器一端的固定杆轴，所述导流器以固定杆轴为轴摆动；当两侧河道来流量发生变化时，导流器两侧的水流冲击力也会发生变化，使得导流器向流量、流速减小的一侧旋转，最终在合外力的作用下再次趋于平衡，这样就达到了让流量增大的一侧河道出口断面面积也得以增大，同时流量减小的另一侧出口断面面积也减小，两侧的出口流速趋于相等或相当，这样即使两河道的来流比发生变化，此导流装置也能达到使两河道交汇处的汇流流态更加平稳的目的。
