Deep sea sediment in-situ analysis device

Abstract

The invention provides a deep sea sediment in-situ analysis device which comprises a feeding funnel, a bracket, a filter element, a transmission unit, a detection unit, a stirring unit, a controller and a sampling bottle. A collecting container is arranged in the feeding funnel; the transmission unit comprises a speed reduction driving machine, a driving gear, a gear ring and a fixing ring; the driving gear rotates to drive the gear ring to rotate; a fixing groove is formed in the gear ring, the fixing ring is fixed in the fixing groove, and the gear ring rotates to drive the sampling bottle to rotate; the detection unit comprises a laser particle size analyzer and a temperature-salinity-depth profiler; therefore, rotation switching of the sampling bottle is realized through the transmission unit; after the sampling bottle finishes sampling, the transmission unit switches the sampling bottle, the detection unit analyzes and detects liquid flow contained in the feeding funnel and storesdetection data, that the data and samples have time synchronism and space same-layer performance is guaranteed, and a basis is provided for the sedimentation effect in the analysis period.

Description

technical field [0001] The invention relates to the technical field of deep-sea sediment collection and analysis equipment, in particular to an in-situ deep-sea sediment analysis device. Background technique [0002] The traditional deep-sea sediment collection is collected first, salvaged and then analyzed. The cycle is long. Due to the impact of environmental changes, the analyzed data has certain distortion when leaving the water surface test. Furthermore, the sedimentation of particles in seawater is a relatively complex dynamic process. The current sediment trap can only show the results of sedimentation within a certain period of time through the collected sedimentation particle samples. Sample collection is completed while in-situ observation of sediments is carried out with effective data such as temperature, salinity and grain size. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides an in-situ analysis device...
