River sediment deposition detection device

Abstract

The invention discloses a river sediment deposition detection device, relates to the field of water conservancy equipment, and adopts the technical scheme that the river sediment deposition detectiondevice comprises a supporting device, a driving device is fixedly arranged on the supporting device, a sampling device for collecting a sediment sample is movably connected to the driving device, andthe driving device drives the sampling device to move in the vertical direction; the device also comprises a storage device for storing compressed air; the supporting device comprises an annular supporting frame and a plurality of supporting legs arranged below the supporting frame in an array mode, a vertical fixed frame is fixedly arranged above the supporting frame, and a driving device is fixedly arranged on one side of the fixed frame; and a floating-sinking air bag is fixedly connected to the outer side of the supporting frame. The device has the beneficial effects that sludge with different depths can be collected at a time, it can be guaranteed that the collected cross section is complete, the sample detection precision is guaranteed, and data of various heavy metal pollution in different forms of sludge on the same cross section can be more effectively observed; the sludge collection efficiency is high and the use is convenient.

Description

technical field [0001] The invention relates to the field of water conservancy detection equipment, in particular to a river sediment deposition detection device. Background technique [0002] In the study of water pollution, the composition analysis of underwater silt is an important part of water body research, and in some specific studies, samples of underwater silt at different depths are also required to analyze the content of heavy metals and other pollutants. Generally speaking, there are roughly two forms of silt: one is black mud with a high moisture content that cannot be formed, and the other is a relatively loose clay layer mixed with plant residues. [0003] The existing sludge sample collection equipment usually collects the shallow surface layer of sludge on the water surface through the collector extending into the water, which cannot collect deeper sludge in sections, and the collected sludge cannot maintain the integrity of the section, which is not conduci...

Problems solved by technology

[0003] The existing sludge sample collection equipment usually collects the shallow surface layer of sludge on the water surface through a collector extending into the water, which cannot collect deeper sludge in sections, and the collected sludge cannot maintain the integrity of the section, which is not conducive to later detection For sludge samples, it is very likely that sample leakage or sample dilution will occur during the sampling ascent process, which will affect the accuracy of sludge sample detection
