Online measuring device for suspended sediment

Abstract

The invention provides an online measuring device for suspended sediment. The online measuring device comprises a submerged pump and a heat insulated box, wherein a water storage tank is arranged in the heat insulated box, and a first inlet is formed in the bottom of the water storage tank and connected with the submerged pump through a connecting pipe; a second outlet and an auxiliary water tankare arranged on the side surfaces of the heat storage tank, a second inlet is formed in the lower part of the auxiliary water tank and communicated with the water storage tank, and a second outlet isformed in the upper part and communicated with the water storage tank; an online cement paste density measuring instrument is arranged in the auxiliary water tank, and a control box is arranged at thetop of the heat insulated box. The online cement paste density measuring instrument and modern technologies such as data acquisition, modern communication, computer network, database and informationanalysis are closely combined with test requirements of hydrologic suspended sediment, the efficient and reliable hydrologic suspended sediment measuring and forecasting equipment with high automationdegree is formed, automatic collection, networking transmission and scientific analysis of suspended sediment information are realized, and timeliness and reliability of collection, transmission, processing and analysis of the suspended sediment information are effectively improved.

Description

Technical field: [0001] The present application relates to the field of sediment measurement, in particular to an online suspended sediment measurement device. Background technique: [0002] The test of suspended sediment content requires two main processes: field sampling and laboratory analysis. Field sampling methods are mostly multi-point sampling and cumulative mixing. The common methods of laboratory analysis are filtration method and pycnometer replacement method. The filtration method requires the water sample to be precipitated for more than 24 hours, and then the upper clear water is sucked out with a siphon hose, and then the concentrated water sample is placed on filter paper for filtration, and then dried in a constant temperature drying box, and finally weighed and calculated. The filtration method needs at least 2 days or more, which is time-consuming and labor-intensive. The pycnometer replacement method uses the method of measuring the density of water sa...

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 sample is sent to the laboratory for analysis, the temperature of the water sample and the laboratory is quite different, which affects the measurement accuracy of the sediment content of the water sample.
