集水装置是同向流斜板的关键部件之一,它既要取出清水,又不能干扰沉泥。因此,该处的水流状态必需保持稳定,更不能出现流速的突变,同时在整个集水横断面上应做到均匀集水。国内采用穿孔梯形断面的集水装置,孔眼流速等,相应阻力很大。在国外专利中,有一种多孔调节板集水装置, The water collecting device is one of the key components of the co-current swash plate. It not only removes clean water, but also does not interfere with the sediment. Therefore, the state of flow at this site must be stable, and even more abrupt changes in flow rates should not occur. At the same time, uniform collection of water should be achieved across the entire cross section of the catchment. Domestic use of perforated trapezoidal cross-section of the water collection device, orifice flow velocity, etc., the corresponding resistance is very large. In foreign patents, there is a porous adjusting plate water collecting device.
