River channel sounding sampling device and use method thereof

Abstract

The invention discloses a riverway sounding sampling device and a using method thereof, and relates to the technical field of riverway sounding sampling, the riverway sounding sampling device comprises a bearing platform, a rotating motor, an electric telescopic rod and a sampler, a hole is formed in the bearing platform, the rotating motor is arranged right above the hole, and a support used for fixing and supporting the rotating motor is arranged on the bearing platform; the electric telescopic rod is connected with the power shaft end of the rotating motor, the sampler is arranged at the telescopic end of the electric telescopic rod, the electric telescopic rod is used for lifting the sampler, the sampler is used for collecting and obtaining a river water sample and bottom mud, and the rotating motor is used for driving the sampler to rotate; according to the use method of the sampling device, the sampling device is installed on a ship body, the riverway sounding sampling device can collect a water sample and a mud sample in combination with the use method of the riverway sounding sampling device, disturbance to a water body is small in the mud sampling process, little water enters the mud sample, the original structure of bottom mud is protected, and the collected mud sample is more beneficial to reflecting the pollution characteristics of the riverway bottom mud.

Description

technical field [0001] The invention relates to the technical field of river depth sounding sampling, in particular to a river depth sounding sampling device and a use method thereof. Background technique [0002] In the treatment of polluted water bodies, collecting sediment for endogenous sediment pollution analysis is an important way to judge whether endogenous sediment treatment is needed, what kind of treatment method to adopt, the depth of treatment, and the disposal of sediment after recycling. According to the classification standard under the international system, the sediment particle size can be divided into coarse sand, fine sand, silt and clay from large to small. Most of the mud extraction devices on the market can only take surface mud samples. The structure of the device for taking deep mud samples is complex, and there is a certain disturbance to the bottom mud, especially the surface bottom mud, which causes the bottom mud to resuspend and release polluti...

AI Technical Summary

Problems solved by technology

The structure of the device for taking deep mud samples is complicated, and there is a certain disturbance to the bottom mud, especially the surface bottom mud, which causes the bottom mud to resuspend and release pollution into the water body

In the actual sampling of the device for collecting the surface sediment, it is often difficult to collect samples or the collected samples cannot accurately represent the pollution characteristics because the surface sludge is easy to lose or the surface sediment is relatively thin.

In addition, most sampling devices cannot be sealed after sampling, resulting in possible dilution of mud samples
