Abstract

The invention discloses a sectional collecting device of a surface flow silt sample, relating to a collecting device for observing a surface flow silt content process and solving the problem that the traditional movable surface flow observing device can only obverse total silt content but cannot realize silt transmitting process observation. A tipping bucket is fixedly arranged on a main transmission shaft; the main transmission shaft is connected with a third driven transmission shaft through a first overrunning clutch, a first driven transmission shaft, a second overrunning clutch, a second driven transmission shaft and a worm and worm wheel speed reducer; the third driven transmission shaft passes through the middle of a stainless steel water dividing disc; a nylon barrel-shaped collector is fixedly arranged on the upper end of the third driven transmission shaft; one end of an outlet elbow is communicated with a first water outlet, and the other end of the outlet elbow is arranged above a disc-shaped water dividing box; each plastic pipe corresponds to one second water outlet; one end of the plastic pipe is communicated with a second water outlet, and the other end of the plastic pipe is communicated with a plastic sample collecting bottle; and the output end of a shunt overflow pipe is arranged above the nylon barrel-shaped collector. The sectional collecting device of the surface flow silt sample is used for collecting surface flow silt mixed samples.

Description

technical field [0001] The invention relates to a collection device used for process observation of sediment content of surface runoff. Background technique [0002] In recent years, the automatic observation of soil and water loss in my country has progressed rapidly. Due to the complex field conditions of soil and water loss monitoring in the field, it is affected by flow velocity, flow rate, water temperature, chemical composition of sediment, particle size of sediment, background light, sedimentation, etc. The automatic observation measurement range is small and the accuracy is poor. Moreover, most of the equipment adopts the principle of photoelectricity and requires a power supply, and most of the soil erosion observations are in the field without power supply; the installation and operation of the equipment are complicated, so it cannot meet the needs of automatic monitoring of water and soil erosion. [0003] The standard closed plot runoff observation system can be ...
