技术领域technical field

Sediment content observation is the most important indicator for monitoring runoff plots, and it is the key to accurately obtain soil erosion. At present, the runoff sediment monitoring in the runoff area still collects the runoff sediment in the way of multi-stage diversion in the collecting bucket, and the sediment content in the collecting bucket is manually sampled and measured. The commonly used method for sampling and measuring the sediment content in the collecting bucket is manual stirring sampling measurement. Manual stirring sampling is to stir the sand-containing water body in the collecting bucket (pool) by manpower, and take out a certain volume of muddy water from the bucket while stirring. water sample. In areas with low sand content, the relative error of manual stirring method is 30%-50%; in areas with high sand content, the average relative error of manual stirring method even reaches 83.05%.
过去的人工取样存在以下缺陷:1、耗费大量人力,取样较慢。2、不能精确控制取样时间,在连续降雨中无法更好的安排取样时间。3、由于人工搅拌取样人为误差大,随机误差大,测量精度低。本技术克服了上述缺陷。The manual sampling in the past has the following defects: 1. It consumes a lot of manpower and the sampling is slow. 2. The sampling time cannot be precisely controlled, and the sampling time cannot be better arranged during continuous rainfall. 3. Due to the large artificial error of manual stirring and sampling, the random error is large, and the measurement accuracy is low. The present technology overcomes the above-mentioned drawbacks.

控制输出:微处理器通过继电器控制电路以及继电器控制对应的抽水、搅拌以及排水等操作。Control output: The microprocessor controls the corresponding pumping, stirring and drainage operations through the relay control circuit and the relay.
用户根据实际的采样和冲洗需求,在控制器端输入采样方案和冲洗方案并存储。设定各继电器的电源开关时间并存储为方案,按下运行方案键后,各继电器根据设定好的起动时间起动,如:According to the actual sampling and flushing requirements, the user inputs the sampling plan and flushing plan on the controller side and stores them. Set the power on/off time of each relay and store it as a plan. After pressing the operation plan key, each relay will start according to the set starting time, such as:
集流桶搅拌电机启动,30s后抽水泵启动,搅拌桶皮带式搅拌器启动,均为边搅拌边采样模式,一次取样完成后集流桶搅拌桨与抽水泵停止运行,搅拌桶皮带式搅拌器启仍运行,30s后蠕动泵运行,将水样从搅拌桶中抽取到定容桶中,二次取样完成后搅拌桶皮带式搅拌器停止运行,电控球阀打开,完成取样。然后搅拌桶电控球阀关闭,将取水管放入清水中,抽水泵启动,开始清洗,搅拌桶皮带式搅拌器启动,蠕动泵启动先对定容桶进行冲洗,冲洗完成后先后关闭蠕动泵与定容桶电控球阀。然后打开搅拌桶电控球阀,完成搅拌桶的清洗,清洗完成后,先后关闭抽水泵和搅拌桶电控球阀。The stirring motor of the collecting bucket is started, the suction pump is started after 30s, and the belt-type agitator of the mixing bucket is started, all of which are in the sampling mode while stirring. After 30s, the peristaltic pump runs, and the water sample is drawn from the mixing tank to the constant volume tank. After the secondary sampling is completed, the belt mixer of the mixing tank stops running, and the electronically controlled ball valve is opened to complete the sampling. Then the electric control ball valve of the mixing tank is closed, the water intake pipe is put into clean water, the pump is started, and the cleaning is started. Electric control ball valve for constant volume bucket. Then open the electric control ball valve of the mixing tank to complete the cleaning of the mixing tank. After the cleaning is completed, close the water pump and the electric control ball valve of the mixing tank successively.
