Embodiment 1

[0031] refer to Figure 1-3 , the present invention provides a new type of deep-sea planktonic microbial in-situ concentration, heat preservation and pressure sampling system, including a sampling cylinder body 1, the sampling cylinder body 1 is a double-layer structure, and a plug-shaped inner cavity is fixed inside the sampling cylinder body 1 104, the top of the plug-shaped inner cavity 104 is provided with a water outlet 5 and a water inlet 6 for transfer, the water inlet 6 is connected with a water inlet component, and the top of the plug-shaped inner cavity 104 is fixedly connected with an end cover 8, and two through-holes Two through holes are respectively set corresponding to the positions of the water outlet 5 and the water inlet 6 for transfer, the plug-shaped inner cavity 104 is fixedly connected with a filter part, the bottom of the sampling cylinder body 1 is provided with a water outlet 7 for sampling, and the water outlet for sampling 7 are respectively communi...

Embodiment 2

[0047] refer to Figure 4 , this embodiment provides a new type of deep-sea planktonic microbial in-situ concentration, heat preservation and pressure sampling system. The difference from Embodiment 1 is that the bottom of the plug-shaped inner cavity 104 is fixed with a bottom plate, and the side plate of the plug-shaped inner cavity 104 is equipped with a filter. A microbial filter 105 is fixedly connected to the filter port, and a microbial filter fixed ring 106 is fixedly arranged on the bottom plate and the side plate of the plug-shaped inner cavity 104. By setting the filter port for seawater on the side plate, it is possible to prevent seawater from pouring into the After that, it directly impacts the microbial filter membrane 105 and causes damage to the microbial filter membrane 105. Since the bottom of the plug-shaped inner cavity 104 is the bottom plate, when seawater enters the sampling cylinder body 1, it first falls on the bottom plate, and the seawater is buffere...

Embodiment 3

[0049] refer to Figure 5 , this embodiment provides a new type of deep-sea planktonic microorganisms in-situ concentrated heat preservation and pressure sampling system, the difference between this embodiment and embodiment 1 is that the deep water pump 3 is connected to the pressure maintaining device 9, and the deep water pump 3 is connected to the pressure maintaining device 9 A one-way solenoid valve 2 is fixedly connected between them, and the one-way solenoid valve 2 is located between the pressure maintaining device 9 and the water inlet 6. The deep water pump 3 can pump part of the seawater into the pressure maintaining device during the process of pumping seawater. In 9, it helps the pressure holding device to store hydraulic pressure. By connecting the deep water pump 3 and the pressure holding device 9, the ability of the pressure holding device 9 to store hydraulic pressure can be increased. During the ascent process, it is found that the pressure holding device 9 ...

Abstract

The invention discloses a novel deep sea planktonic microorganism in-situ concentration heat preservation and pressure maintaining sampling system. The system comprises a sampling barrel body, the sampling barrel body is of a double-layer structure, a plug-shaped inner cavity is fixedly formed in the sampling barrel body, a water outlet and a water inlet which are used for transferring are formed in the top of the plug-shaped inner cavity, the water inlet communicates with a water inlet assembly, an end cover is fixedly connected to the top of the plug-shaped inner cavity, two through holes are formed in the end cover, the two through holes correspond to the water outlet and the water inlet which are used for transferring respectively, a filtering portion is fixedly connected to the plug-shaped inner cavity, a water outlet for sampling is formed in the bottom of the sampling barrel body, and the water outlet for sampling communicates with a pressure maintaining device and a water outlet pipeline respectively; a heat preservation material layer and a temperature control assembly are fixedly connected between double-layer structures of the sampling barrel body, and the temperature control assembly is electrically connected with a controller. The system is reasonable in structure and convenient to operate, and sampling can be completed on the premise of keeping the in-situ pressure of a sample.

Description

technical field [0001] The invention relates to the field of deep-sea planktonic microorganism sampling, in particular to a novel deep-sea planktonic microorganism in-situ concentration, heat preservation and pressure-holding sampling system. Background technique [0002] Deep-sea phytoplankton is an emerging deep-sea resource. The study of deep-sea phytoplankton is of great significance in many aspects such as the origin of life, biology, research and development of new drugs, and environmental protection. However, due to the limitation of its environment, there are certain difficulties in sampling. The existing deep-sea sampler is limited by the volume of the sampling cylinder. In the deep sea with low microbial density, only a small number of microbial samples can be obtained in a single sampling, and it is difficult to maintain the in-situ pressure of the sample. [0003] Aiming at the deficiencies of traditional samplers, this product designs a new type of deep-sea mic...
