Water measuring device based on bottom slope and bottom slope gradient determination method
The invention relates to a bottom slope-based water measuring device and a bottom slope gradient determination method, and the bottom slope-based water measuring device comprises a thin-walled weir which is installed on a flow monitoring section of a channel to be measured, and the bottom of the thin-walled weir is provided with a sand washing hole; a bottom slope is designed on a flow monitoring section advancing channel groove section of the channel to be detected; the terminal controller generates a detection control signal and a starting control signal when measuring the water level, and generates a closing control signal when receiving the water level in the channel; the water retaining gate is arranged at the position, corresponding to the sand washing hole, of the thin-walled weir and used for opening or blocking the sand washing hole, and the width of the water retaining gate is larger than that of the sand washing hole; the motor is used for controlling opening and closing of the water retaining gate according to the starting control signal or the closing control signal; the water measuring facility measures the water level in the channel to be measured according to the detection control signal. By adopting the measures, sediment deposition at the water measurement facility is avoided, and the precision of water measurement data is improved.
本发明涉及一种基于底坡的量测水装置及底坡坡度确定方法，所述基于底坡的量测水装置包括：薄壁堰，安装在待测渠道的流量监测断面上，薄壁堰的底部开设有冲砂孔；待测渠道的流量监测断面行进渠槽段设计有一底坡；终端控制器在测量水位时产生检测控制信号及启动控制信号，并在接收到渠道中的水位时产生关闭控制信号；挡水闸门，设置在薄壁堰上对应冲砂孔的位置，用于打开或封堵冲砂孔，挡水闸门的宽度大于冲砂孔的宽度；电机用于根据启动控制信号或关闭控制信号控制挡水闸门的启闭；量水设施根据检测控制信号测量待测渠道中的水位。通过采取上述措施避免量测水设施处的泥沙淤积，提高了量测水数据的精度。
