摘要
为了适应灌区末级渠道量水需要,设计了一种使用便捷、量水精度较高、农民易接受的量控水新装置。以U型渠道为闸墩,通过调节布置在渠道内的平板闸门来实现量水与控水一体化,并对5种开度下闸前、闸后水位与对应的流量进行了组合试验。试验结果表明:水位和流量的相关系数均大于0.98,相对误差小于5%,适合末级渠道量控水。
In order to meet the demand of water measurement in end-stage canal, a new measurement and control device with the characteristics of high precision and convenience was designed. The device, taking the U shape canal as gate pier, can unite water measurement and regulation by adjusting flat valve in the canal. The experiments for the water levels at upstream and downstream of the gate and the flow rate are conducted under the conditions with 5 different valve open sizes. The result shows that both the correlation coefficients of water level and flow rate equation are more than 0.98, while the relative error is less than 5%. So, the device is suitable for water measurement of en＆stage canal.
