Description

Technical Field

[0001] The utility model belongs to the technical field of runoff sediment monitoring, and specifically relates to a runoff sediment monitoring device for a runoff plot. Background Art

[0002] Soil and water conservation refers to the preventive and control measures taken against soil and water loss caused by natural factors and human activities. Since the 1980s, we have entered a new stage of comprehensive soil and water loss control with small watersheds as units. Small watersheds refer to relatively small closed catchment areas formed by watersheds and outlet sections. The maximum watershed area generally does not exceed 50 square kilometers. The occurrence and development of soil and water loss occurs in small watersheds with certain regularity. In order to monitor the soil and water conservation runoff area, it is necessary to collect sediment through collection tubes.

[0003] A document with a publication number of (CN213455743U) was retrieved and disclosed a runoff area sediment monitoring device, including a diverter barrel, the diverter barrel is composed of a diverter barrel body and a diverter barrel upper cover, the upper end of the diverter barrel body is fixedly connected to the diverter barrel upper cover by bolts, the center of the upper end of the diverter barrel upper cover is fixedly connected to the first liquid level gauge by bolts, and a drain valve is provided at the bottom of the diverter barrel body. In this runoff area sediment monitoring device, the long diverter pipe passes through the outer wall of the collecting barrel and then becomes a vertical circular pipe. The vertical circular pipe allows the excess runoff in the diverter barrel to flow smoothly into the collecting barrel, ensuring the smooth change of the water surface in the collecting barrel, and the runoff water level process data is more accurate.

[0004] The above-mentioned device can allow excess runoff in the diversion barrel to flow smoothly into the collecting barrel through a vertical circular pipe, thereby ensuring the smooth change of the water surface in the collecting barrel and making the runoff water level process data more accurate. The float is slidably connected to the first liquid level gauge and the second liquid level gauge respectively, thereby improving the accuracy of the water level data. However, it is unable to separate sediment from water, resulting in the inability to accurately measure the sediment content in the outlet water, which makes the device itself have limitations.

[0005] To this end, we propose a soil and water conservation runoff plot monitoring sediment collector to solve the above-mentioned problems. In view of this, the present utility model is specially proposed. Utility Model Content
