Embodiment Construction

[0022] As shown in the figure, an underwater undisturbed soil sampler includes a grab bucket 1, a steel rope 2, a guide wheel 4, a gear counter 5, a first synchronous wheel 6, a hand crank 7, an oil pipe 8, an oil pipe wheel 9, a second Two synchronous wheels 10, synchronous belt 11, oil pressure station 12;

[0023] The first synchronous wheel 6 is connected with the second synchronous wheel 10 through a synchronous belt 11;

[0024] A steel rope 2 is wound on the first synchronous wheel 6, and the steel rope 2 is fixedly connected to the grab bucket 1 by bypassing the guide 4; the guide 4 meshes with the gear counter 5;

[0025] The second synchronous wheel 10 is wound with an oil pipe 8, and the oil pipe 8 is fixedly connected with the grab bucket 1 around the oil pipe wheel 9, and one end of the oil pipe near the second synchronous wheel 10 is connected with the oil pressure station.

[0026] The lead 4 is provided with a groove, and the inner wall of the groove is a sine...

Abstract

The invention discloses an underwater undisturbed soil sampler which comprises a grab bucket, a steel rope, a guide wheel, a gear counter, a first synchronous wheel, a hand crank, an oil tube, an oil tube wheel, a second synchronous wheel, a synchronous belt and an oil pressure station. The underwater undisturbed soil sampler has the advantages that when the underwater undisturbed soil sampler is utilized to conduct sampling on underwater soil, original characters of a sample can be better kept, and the underwater undisturbed soil sampler is simple in component, convenient to operate and free of external power source.

Description

technical field [0001] The invention relates to a soil sample collection device, in particular to an underwater undisturbed soil sampler. Background technique [0002] Underwater sediments and lake center sediments are of great significance for revealing environmental changes, depositional processes, and pollutant migration. Sampling often needs to keep the original properties of the sample, such as the original sequence and deposition thickness, as well as possible. At present, sediment samplers are mainly columnar sampling. The structure of the columnar sampler is relatively complicated. Usually, a vacuum pump and a pressure pump are used for sample collection. When the sampler is pulled out, the pressure pump expands the rubber to seal the bottom of the sampling tube, so the original shape of the sample can be better maintained. This type of device has many components and a large volume, requires an external power supply and is relatively expensive. Contents of the in...
