Pump station forebay vortex elimination method based on image recognition technology
The invention relates to a pump station forebay vortex elimination method based on an image recognition technology, which comprises a water pump, a pump station forebay and a pump station control system, a monitoring device is installed at a diffusion section of the pump station forebay, the length of the pump station forebay is set to be L, and the monitoring device locates and monitors a 1.5 L area of the pump station forebay; the monitoring device is connected with the image processing system and the pump station control system; a diffusion section of a forebay of the pump station is divided into a plurality of grids, and a water spraying turbulence device is arranged in the center of each grid and is controlled by a pump station control system; when it is found through the image processing system that a vortex with the diameter larger than 1 m exists in the monitoring area of the forebay of the pump station, the pump station control system adjusts the rotating speed of an impeller of the pump station and changes the flow of a water pump, and therefore the original flow state of the forebay is disturbed, and the vortex elimination purpose is achieved; when the working condition changes and the speed of the water pump cannot be adjusted, the monitoring device positions the vortex, and the pump station control system controls the turbulent flow device of the corresponding grid to spray water flow to disturb the original flow state of the vortex and eliminate the vortex.
本发明涉及一种基于图像识别技术的泵站前池消涡方法，包括水泵、泵站前池、泵站控制系统，在泵站前池的扩散段安装监测装置，设泵站前池长度为L，监测装置定位监测泵站前池1.5L的区域；监测装置连接图像处理系统，且监测装置与泵站控制系统相连；在泵站前池的扩散段划分出若干方格，在方格中心设置喷水扰流装置，喷水扰流装置由泵站控制系统控制；当通过图像处理系统发现泵站前池的监测区域存在直径大于1m的漩涡时，由泵站控制系统调节泵站的叶轮转速，改变水泵流量，从而扰乱前池原有流态，达到消涡的目的；当工况变化导致水泵无法调速时，监测装置将定位漩涡，由泵站控制系统操控对应方格的扰流装置喷射水流，扰乱漩涡原有的流态，消除漩涡。
