Abstract

The invention discloses an annular sealed tank sampling device with an automatic compensation function and a sampling method. The device comprises a sampling rod, a first peristaltic pump, a second peristaltic pump, a tee valve, a sample storage and a compensation device, wherein the tee valve is connected to the sampling rod, the first peristaltic pump and the second peristaltic pump through flexible pipes, the first peristaltic pump is communicated with the sample storage, the second peristaltic pump is communicated with the compensation device, the sample storage and the compensation device are respectively arranged on a lower support and an upper support of a supporting table, the sampling rod is inserted into an annular sealed tank, and the tee valve, the first peristaltic pump and the second peristaltic pump are all subjected to sequential control of a controller. An equivalent volume method is adopted to ensure that the volume of a taken sample is equal to that of water added for compensation, so that the total water amount of the tank is maintained to be constant, various water power parameters are guaranteed to be unchanged in a test, and the accuracy and repeatability of experimental results are improved.

Description

technical field [0001] The invention relates to a sampling device and a sampling method of an annular airtight water tank with an automatic compensation function, belonging to the research field of test sampling of an annular airtight water tank. Background technique [0002] The water bodies of natural rivers generally contain a certain amount of sediment, which will have an important impact on the flow structure characteristics of the water flow, the evolution of the river course, and the construction of water conservancy projects. At present, the research mainly relies on field tests and indoor tests of straight water tanks. However, the length of straight water tanks is limited, and both the inflow and outflow have an impact on water flow. Ring-shaped closed tanks are more suitable for studying the interaction between water and sand and pollution. The mechanism of migration and transformation of substances. Theoretically speaking, the ring-shaped closed water tank can s...
