Combined flow adjusting device and flow adjusting method for large-diffusion-angle forebay
The invention discloses a combined flow adjusting device and flow adjusting method for a large-diffusion-angle forebay. The device comprises large-divergence-angle forebay bodies, a sill and a stand column set, the still is linear and located at the front end of an inlet of the forebay bodies in the positive water flow direction, the left side and the right side of the stand column set are symmetrically arranged at the front ends of side holes in the left side and the right side of a pump station inlet, the left stand columns or the right stand columns is composed of multiple columns of the stand columns, and in the left or right stand column set, the stand columns in any two columns are distributed in a staggered manner. According to the combined flow adjusting device and flow adjusting method for the large-diffusion-angle forebay, the combined flow adjusting measure comprising the sill and the stand columns is suitable for various pump station forebay bodies, the problems that side holes do not have inflow in the large-divergence-angle pump station forebay bodies and vortex areas exist in side units can be effectively solved, beneficial water inlet conditions are provided, safe and efficient operation of the pump station is facilitated, and the device and the method are simple in structure, reliable in technology, easy to implement, wide in application prospect and large in economic benefit.
一种用于大扩散角前池的组合式整流装置及整流方法。包括大扩散角前池、底坎以及立柱组,所述底坎为一字型,位于正水流方向前池进口前端;所述立柱组分左右两侧在泵站进口左右两侧边孔前端对称布置,左侧或右侧的立柱组均由若干列立柱构成;左侧或右侧的立柱组中,任意两列中的立柱呈交错式分布。本发明提供的包括底坎及立柱的组合式整流措施,适用于各种泵站前池中,可有效解决大扩散角泵站前池存在的边孔不进流以及边机组存在涡区的问题,提供有益的进水条件,有利于泵站的安全高效运行;本发明结构简单,技术可靠,易于实施,应用前景广阔,经济效益大。
