Gravity vibration composite deep sea sampler with anti-disturbance structure

Abstract

The invention relates to the technical field of sampling equipment, in particular to a gravity vibration composite deep sea sampler with an anti-disturbance structure, which comprises a deep sea sampler body. The deep sea sampler body comprises a sampler putting frame, and a damping mechanism is fixedly mounted at the top end of the sampler putting frame. Anti-disturbance mechanisms are fixedly mounted on the two sides of the sampler putting frame, each anti-disturbance mechanism comprises two vertical plates, and sliding grooves are formed in the front faces of the vertical plates. By arranging a ground auger, a first supporting rod, a rotating rod, the vertical plates, the sliding grooves, sliding blocks and limiting rods, the position of the sampler putting frame on the seabed can be fixed, sampling by a sediment sampling mechanism and a deep water sampling mechanism is facilitated, the situation that due to the fact that the sampler putting frame is subjected to large pressure intensity on the seabed, operation is unstable is prevented, and collected samples are prevented from being disturbed.

Description

technical field [0001] The invention relates to the technical field of sampling equipment, in particular to a gravity vibration composite deep-sea sampler with an anti-disturbance structure. Background technique [0002] The deep sea area is rich in oil, natural gas and other oil and gas resources, and it is the largest potential strategic resource base on the earth that has not been fully understood and utilized by human beings. With the intensification of energy problems, the importance of deep-sea energy development and research has become increasingly prominent. The sampling of seabed sediment and seawater is the first step in finding and exploring marine oil and gas resources and microbial resources. It is the basis for engineering geological survey and environmental ecological research. Sediment samplers are widely used in marine scientific research. Research marine biology, marine ecology, marine geology and other scientific issues. [0003] Seabed sampling is the w...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of gravitational vibration composite type deep-sea sampler with anti-disturbance structure, to solve the existing gravitational vibration proposed in the above-mentioned background technology After the composite deep-sea sampler enters the seabed, most of them cannot penetrate into the seabed, resulting in insufficient stability of the sampler, which is likely to bring disturbance to the sampling process and affect the effect of the sampling operation of the deep-sea sampler
