Abstract

The invention discloses an automatic sampler of undisturbed sediment deposits, and relates to the environment analysis technology. The automatic sampler comprises a power supply part, a cylinder body part, a sampling head, and a seal part. After the automatic sampler enters sediment deposits, a pressure switch is closed by the extrusion between the power supply housing and the sampling cylinder fixed part, and a deceleration motor is started to drive the sampling cylinder and a stainless steel knife edge to rotate and sampling; when the distance between the power supply housing and an annular gravity hammer reaches the detection range of a proximity switch sensor, the sampling is stopped; during the lifting process of the sampler, a rubber diaphragm seals the lower part of the sampling cylinder. The automatic sampler of undisturbed sediment deposits of the invention is specially applicable to undisturbed sampling devices for sediment deposits of rivers, lakes, and neritic regions, and has an obvious advantage for environment with a relatively hard deposition layer; and the invention allows a quick and effective sampling to deposits, and realizes an effective analysis to deposit samples.

Description

technical field [0001] The invention relates to an automatic sampler, in particular to an undisturbed bottom mud sediment. Background technique [0002] The rapid development of environmental analysis technology has greatly improved the pretreatment and detection level of environmental samples, but the current development of sampling technology, especially for the collection of undisturbed sediment samples, is not only limited by the environmental geographical location, but also by the The sampling instrument itself is difficult to sample, and the process is time-consuming and labor-intensive. At present, the undisturbed sediment sediment sampling instruments commonly used in the world are gravity-type or gravity-type samplers equipped with pneumatic devices. These samplers work better in environments with low sediment density and loose texture. Larger sediments with relatively thick sediment layers often cannot collect satisfactory sample quantity and quality. Contents o...
