Delay-start type multi-motor synchronous vibrating subglacial water sediment sampler

Abstract

The invention discloses a delay-start type multi-motor synchronous vibrating subglacial water sediment sampler, which comprises an electric pressure chamber, a vibration pressure chamber, a sampling tube component and a guiding counterweight unit, wherein the electric pressure chamber is arranged at the top end, and the vibration pressure chamber, the sampling tube component and the guiding counterweight unit are sequentially assembled at the lower part of the electric pressure chamber; the lower end of the electric pressure chamber is connected with the upper end of the vibration pressure chamber through a vibration damping unit, and the lower end of the vibration pressure chamber is connected with the upper end of the sampling tube component through a connecting locking device; the upperend of the guiding counterweight unit is suspended at the lower end of the sampling tube component. The delay-start type multi-motor synchronous vibrating subglacial water sediment sampler disclosedby the invention has the beneficial effects of being beneficial to obtain deep sediment samples, overcoming the defect that the external guide support in marine sediment sampling equipment can not beused, and realizing the vibration mode of the sampler in a single direction. The whole sampler adopts a modular design, and is convenient to disassemble and assemble, maintain and replace, and the surface working time is saved.

Description

technical field [0001] The invention relates to a subglacial water body sediment sampler, in particular to a delay start type multi-motor synchronous vibration type subglacial water body sediment sampler. Background technique [0002] At present, the Antarctic continent is covered by ice and snow all the year round. After millions of years of accumulation, a large amount of sediment has accumulated at the bottom of the Antarctic ice shelf and in the water body of the subglacial lake. important scientific significance. In addition, since the water body under the Antarctic ice shelf and the subglacial lake is in a low-light or no-light state all year round, scientists infer that there must be primitive life forms or independently evolved microorganisms in the sediments at the bottom of the Antarctic ice shelf. Research brings new opportunities. [0003] In recent years, with the continuous development of hot water drilling technology, the frontier of world Antarctic scientif...
