Problems solved by technology
China's existing deep-sea sediment sampler can take samples of sediment, water, gas and natural gas hydrate in the deep sea and keep them under pressure. However, there is no equipment for secondary pressure-holding sampling transfer in my country. The pressure-holding transfer device docked with the sampling device will promote the research and development of pressure-holding transfer of natural gas hydrate in China

Embodiment Construction
[0024] The following examples can make those skilled in the technical field understand the present invention more comprehensively, but do not limit the present invention in any way.
[0025] like Figure 1~2 As shown, the present invention provides a specific embodiment of a sample liner jaw for pressure-holding transfer of hydrate deposits, including a push cylinder 1, a threaded rod 2, a nut sleeve 3, a feeding rotator 4, a special screw 5, a top Rod 6, slide rod 7, ejector rod shaft 8, fastening screw 9 and needle changer 10; the jaws are in the form of inner jaws, which solves the problem of space occupation and improves the success rate of grasping. Because the sample tube is made of plastic, if the external claws are used, the sample tube will be squeezed, deformed or even broken during the process of grabbing the sample tube, which seriously interferes with the in-situ characteristics of the sampled hydrate deposits. Only use the form of inner claws to grasp the sample...

The invention relates to a pressure-holding transfer device, and aims to provide a sample liner jaw for pressure-holding transfer of hydrate deposits and an application method thereof. The invention includes a push cylinder, a threaded rod, a nut sleeve, a feed rotor, a special screw, a push rod, a slide rod, a push rod shaft, a set screw and a needle changer; the push cylinder and the nut sleeve are threadedly connected, There is a threaded connection between the feed rotor and the threaded rod, and the front end of the feed rotor is embedded between the nut sleeve and the push cylinder; between cylinders. The beneficial effects of the present invention are: the claw is designed as an inner claw, which takes into account the stability of the claw and the space occupation of the claw, and the inner claw can be easily embedded in the sample liner; the threaded rod is driven by the rotation of the feeding rotor, Push the ejector rod to act on the built-in replacement needle to clamp the sample liner firmly; during the pull-back process, the top of the claw is set into an inverted cone shape to meet the smooth pull-back of the threaded rod.
Description
technical field [0001] The invention relates to a pressure-holding transfer device, in particular to a sample liner jaw for pressure-holding transfer of hydrate deposits and an application method thereof. Background technique [0002] Natural gas hydrate (ClathrateHydrate) in deep-sea sediments, commonly known as "combustible ice", is a high-quality and efficient fuel that can be used as a high-quality energy source. His energy density is very high, according to theoretical calculations, lm 3 Saturated natural gas hydrate can release 150-200m under standard conditions 3 The energy density of methane gas is 10 times that of other unconventional gas source rocks (such as coalbed methane and black shale), and 2 to 5 times that of conventional natural gas. [0003] The formation of natural gas hydrate needs to be formed under certain conditions, requiring suitable temperature, pressure, gas saturation, water salinity, pH value, etc. Most of the gas hydrates on land are produc...
