AI Technical Summary

Problems solved by technology

Existing measurement devices are limited by hardware conditions (for example, the opening and closing time of electric valves is long), and it usually takes several minutes to process the samples
The full-scale measuring device can collect and measure the entire runoff process when the runoff is not large. It takes 40s for each measuring barrel (each measuring barrel capacity 100L) to reach the set water level, and the alternate measurement of two measuring barrels cannot be completed within 40s.
In addition, the existing sampling-type and full-volume automatic runoff sediment measurement devices are prone to residual silt and sediment on the bottom and inner wall of the measuring barrel during the measurement process. Failure to clean it in time will lead to inaccurate measurement data of runoff and sediment concentration. even damage the measuring device

Abstract

The invention discloses a self-cleaning single-barrel overturning type runoff sediment automatic measurement device, comprising: a measuring mechanism, the measuring mechanism includes a measuring platform, a measuring barrel is arranged on the top of the measuring platform, and a weighing sensor is fixedly connected to the bottom of the measuring platform. The weighing sensor is electrically connected to the controller; the pouring mechanism includes an electric push rod, the output end of the electric push rod is hinged to the measuring barrel, and the other end of the electric push rod is hinged to the measuring platform; the dredging mechanism includes a dredging motor and The drive assembly, the output end of the dredging motor is fixedly connected to the drive assembly, the end of the drive assembly away from the dredging motor is provided with a scraper, and the drive assembly is located on the top of the measuring barrel; the sampling mechanism includes a sampling tube, which is located on the top of the measuring barrel, and the sampling tube rotates Connected to the sampling holder. The device can quickly and accurately measure samples, and can realize automatic dredging to avoid the impact of sediment on the measurement structure.

Description

A self-cleaning single-barrel overturning automatic measuring device for runoff and sediment technical field The present invention relates to measurement technology field, particularly relate to a kind of self-cleaning single-barrel overturning type runoff sediment automatic measuring device. Background technique [0002] In the soil erosion monitoring work at all levels of soil and water conservation monitoring sites in my country, standard runoff plots or natural slopes The runoff and sediment content of the runoff field are very important observation indicators, which play an important role in the protection of water and soil resources and the governance of the ecological environment. face is important. The measurement of current runoff and sediment content is still mainly based on manual observation, and its measurement result is easily affected by human factors. interference, large error and long measurement time. In recent years, the automatic measuring devic...
