Large-size movable suspended matter section high-resolution measurement and slidable sampling device

Abstract

The invention provides a large-size movable suspended matter section high-resolution measurement and slidable sampling device. The large-size movable suspended matter section high-resolution measurement and slidable sampling device comprises a barrel body, a movable platform frame, an electric stirrer, a motor, an optical backscatter turbidimeter, a first ASM optical measurement device and a second ASM optical measurement device, wherein the barrel body, the electric stirrer and the motor are arranged on the movable platform frame; the barrel body is used for storing a sample to be detected; the motor drives the electric stirrer to rotate; the electric stirrer is arranged at the bottom end of the barrel body; an OBS (Optical Burst Switching) probe of the optical backscatter turbidimeter is arranged in the barrel body; optical sensor matrixes of the first ASM optical measurement device and the second ASM optical measurement device are arranged in the barrel body; and the measurement range of the first ASM optical measurement device is greater than that of the second ASM optical measurement device. The large-size movable suspended matter section high-resolution measurement and slidable sampling device has high resolution and can be used for observing a real-time dynamic process, and the measurement of a time-space continuous concentration value is finished; and meanwhile, the large-size movable suspended matter section high-resolution measurement and slidable sampling device also can be used for carrying out real-time monitoring of the salinity, temperature and turbidity of specific positions.

Description

technical field [0001] The invention relates to water conservancy and water transport engineering scientific research technology, in particular to a high-resolution measurement and slidable sampling device for large-scale movable suspended matter profiles. Background technique [0002] The settling cylinder is a widely used measurement device for sediment settlement characteristics, but the factors affecting sediment settlement are very extensive, mainly including particle size, density, composition, gradation, geometry, water temperature, salinity, turbulence intensity , Reynolds number, sand concentration, flocculation, flow velocity, ion concentration, etc. Therefore, the research results through the settling tank are only valid under certain applicable conditions and applicable scope. [0003] Moreover, the existing settling tubes also have the following disadvantages: 1. The temporal and spatial resolution is low, the data in the real-time observation during the dynami...

Therefore, the research results through the settling tank are only valid under certain applicable conditions and scope

[0003] Moreover, the existing settling tubes also have the following disadvantages: 1. The temporal and spatial resolution is low, the data in the real-time observation during the dynamic process is loose, the error is large, and there is no built-in monitoring device; 2. The old device has a small volume and insufficient lateral dimensions. Its internal instrument activities greatly disturb the solution, and it is inconvenient to fix and move; 3. The sampling port is fixed and rigid and the space distribution is loose, which is unfavorable for operation and high-density data collection; all
