River sediment content measuring device and method

Abstract

The invention discloses a river sediment content measuring device and method. According to the river sediment content measuring device and method, the problems that in the prior art, manual measurement of the river sediment content is large in danger, large in workload, and low in measurement accuracy are solved, and the beneficial effect of accurately and relatively quickly achieving a river sediment content value is achieved. According to the following scheme, the river sediment content measuring device comprises a shell; the exterior of the shell is provided with a mortar online density measuring instrument and a water depth measuring instrument which are connected with a controller, and the controller is connected with a remote terminal through the Internet of Things; the shell is provided with a water inlet and a drainage port for water feeding and drainage; and a water sucking piece and a water draining piece are arranged in the shell, and both connected with the controller to drive the shell to ascend and descend in a river. Through the mortar online density measuring instrument and the water depth measuring instrument, the content of sediment at different depths is averagedto obtain the average sediment content value of a measured point.

Description

technical field [0001] The invention relates to the field of sediment content measurement, in particular to a river sediment content measurement device and method. Background technique [0002] Sediment content testing requires two main processes: field sampling and laboratory analysis. Sampling in the field generally requires manual boat use of samplers to take water samples from water streams. Commonly used are horizontal sampler and bottle sampler. If the water sample is taken from a fixed measuring point, it is called point sampling; if the sampling bottle moves at a constant speed from top to bottom on the measuring line, it is called depth sampling, and the water sample represents the average condition of the measuring line. . When measuring the sediment content of a section in a watershed, it is necessary to select several measuring points on the cross section, and each measuring point takes samples at different water depths along the vertical line, and finally tak...

Problems solved by technology

However, since the measurement accuracy of the water sample density is greatly affected by the ambient temperature, when the field water samples are sent to the laboratory for analysis, the temperature of the water in the basin is quite different from the temperature of the laboratory, which affects the measurement accuracy of the sediment content of the water samples.

These methods of operation require a large number of staff to be stationed at the monitoring point all year round to take samples, and the laboratory analyzes and calculates the monitoring data, which consumes a lot of manpower and material resources. Especially when it is raining, the sampling frequency is required to be higher. At this time, the task is not only heavy, but also particularly dangerous.
