Embodiment Construction

[0060] see Figure 1~5 , The deep-sea sediment multiple pressure maintenance transfer equipment of the present invention includes a connector 1, a main ball valve 2, a pressure maintenance cylinder 3, a secondary telescopic mechanism 4, a positioning mechanism 5, a control box 6 and an accumulator 7. Among them, there are screw connections between the connector 1 and the main ball valve 2, and between the main ball valve 2 and the pressure maintaining cylinder 3, and sealing rings are used for pressure maintaining and sealing.

[0061] The connector 1 is provided with a sampling channel 100 and a sampling channel 102 which communicate with each other, which is a three-way structure. The sampling channel 100 extends along a straight line, and the sampling channel 102 is vertically connected to the middle of the sampling channel 100. Wherein, the sampling channel 100 faces away from the One side of the main ball valve 2 is connected to the original sample sampler, and the outlet...

Abstract

The invention discloses multi-time pressure maintaining transfer equipment for deep-sea sediments. The multi-time pressure maintaining transfer equipment comprises a pressure maintaining barrel and a sampling device and is further provided with a connector and a main ball valve, wherein the connector is internally provided with a sampling channel and a sample discharging channel which are communicated with each other; the pressure maintaining barrel is in butt joint with the sampling channel by the main ball valve; the sampling device comprises a sampling barrel located in the pressure maintaining barrel, a multi-grade retracting mechanism for driving the sampling barrel and a piston located in the sampling barrel, wherein the sampling barrel is provided with a sampling working position which extends out of the sampling channel via the main ball valve and a sample discharging working position located in the connector; the piston is used for pushing away a sample from the sampling barrel to enter the sample discharging channel when the sampling barrel is located at the sample discharging working position. The multi-time pressure maintaining transfer equipment adopts a brand-new sub-sampling scheme, namely the retracting mechanism is used for a plurality of times so as to realize sub-sampling and transferring of the sample in a pressure cavity; the defects in the prior art that the volume is large and the utilization rate of the sample is not high are overcome.

Description

technical field [0001] The invention relates to the field of deep-sea exploration and research equipment, in particular to a device for multiple pressure-holding and transfer of deep-sea sediments. Background technique [0002] Ocean engineering is an immature technical field. Deep-sea sediment sampling is one of the basic means of deep-sea environment and resource investigation. After decades of investigation practice, a variety of effective sediment sampling methods have been formed, but The development of sampling equipment has been relatively slow. [0003] At present, the devices used for sampling mainly include the following categories: [0004] Multi-tube sampler, which uses gravity to collect seafloor surface sediment and its overlying water; [0005] Deep sea towed sampler for collecting suspended particles; [0006] TV grab sampler for collecting sediment and surface minerals. [0007] However, for the seabed sediment samples collected by the above-mentioned sa...
