The height of the mud guard is one fifth to one fourth of the outer side wall of the groove body, and 2-3 mud guards (8) can be overlapped when necessary to ensure that the height is adjustable.
The sampling device is integrated with a flow velocity sensor, a flow sensor and a water sample water sampling pipe and is fixed on a fastener arranged on the upper surface of the mudguard.
When the device is used, firstly, a water sample emptying pipe valve is closed, a sampling device to be used is connected, and water is injected, wherein the injected water amount is determined according to the experimental requirement, but the wave making device and the sampling device must be submerged; then, the sediment or the sediment is laid at a proper position according to the requirement, and then the wave making device is opened to enable the water sample to circularly flow along one direction at different flow rates. And (4) closing the wave maker after the experiment is finished, opening a valve of the water sample emptying pipe to empty the water sample, and cleaning bottom mud or bottom sand if necessary.
The utility model has the advantages that:
1. the annular water tank of the utility model is convenient for controlling variables, and can freely control variables according to annular time parameters to deeply explore various problems;
2. the annular water tank of the utility model has the advantages of small resource occupation, high material utilization rate, wide manual operation atmosphere, low labor intensity around the annular shape;
