Problems solved by technology

There are many kinds of sediment samplers commonly used at present. Due to the high water content and fluidity of the sediment, when the sampling device grabs the sediment, the sediment will be lost with the water. The sediment sample is greatly disturbed by the water flow and is incomplete, which affects the sample. test result

Abstract

The invention relates to a river and lake sample collector which comprises a carrying platform, a power driving device, a sampling device, a control device and a power supply device, the power driving device is arranged on the side face of the carrying platform, and the sampling device, the control device and the power supply device are fixedly arranged on the carrying platform. The lower end of the sampling device penetrates through the bottom of the carrying platform and can extend downwards, an anti-backflow device is arranged at the lower end of the sampling device, and the lower end of the sampling device can be blocked into a closed sample cavity by the anti-backflow device; and the power supply device is in power supply connection with the power driving device, the sampling device and the control device, and the control device is in communication connection with the power driving device and the sampling device and used for controlling the power driving device and the sampling device to operate. The collector can automatically complete sampling, can collect bottom mud samples and water quality samples at different depths, and can keep the state of the collected bottom mud not disturbed by water flow.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a river and lake sample collector. Background technique [0002] Sediment, usually a mixture of clay, silt, organic matter and various minerals, is formed by depositing at the bottom of a water body after long-term physical, chemical and biological actions and water transport. In order to study the accumulation, distribution, transformation and migration of pollutants discharged into the water body in the sediment, it is necessary to collect undisturbed sediment samples from different depths in the underwater area to detect the pollutant content, which requires a dedicated Sediment sampling device. There are many kinds of sediment samplers commonly used at present. Due to the high water content and fluidity of the sediment, when the sampling device grabs the sediment, the sediment will be lost with the water. The sediment sample is greatly disturbed by the water ...
