Embodiment Construction
[0030] 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.
[0031] Such as figure 1 Shown, a kind of seabed abyss macrobiological trapping and pressure-holding sampling device includes a sampling cylinder 4. An accumulator 7 and a ball valve 13 are also included.
[0032] The sampling cylinder 4 is placed in the support seat, and is fixed together with the support seat 10 through a connecting ring, and the lower part of the support seat 10 is fixed on the landing frame 11 by bolts 12 . The inlet end of the sampling cylinder 4 is provided with an opening and is connected to the ball valve 13 through a flange, and the outlet end is perforated and connected to the accumulator 7 through the capillary 6 . The accumulator 7 is fixed on the accumulator fixing frame 9, and the accumulator 7 is provided with an accumulator charging valve 8. There is a piston 7-...

The invention relates to the technical field of seabed abyss organism sampling, in particular to a seabed abyss macro organism trapping and gastight sampling device. The device comprises a sampling cylinder, an energy accumulator and a ball valve; the sampling cylinder is placed in the support seat; the inlet end is provided with an opening and is connected with the ball valve through a flange; the outlet end is opened and is connected with the energy accumulator through a capillary; the energy accumulator is fixed arranged on an energy accumulator fixing frame, and the accumulator accumulatoris provided with an energy accumulator inflation valve; the inlet end of the sampling cylinder is provided with a correlation-type infrared photoelectric organism detector; the ball valve comprises avalve body and a valve rod, a part of the valve body is placed in a support seat, and the valve body is provided with a hole having a same size as the opening of the inlet end of the sampling cylinder; the lower end of the valve rod is connected with a keyway at the top of the valve body, and the upper end of the valve rod is connected with a keyway of a turbine; the turbine is meshed with a worm, and the end of the worm is connected with a motor shaft. The device provided by the invention can be used to complete gastight sampling, and the pressure of obtained biological samples is substantially maintained to be an in-situ pressure, so that the survival rate of organisms is greatly improved.
Description
technical field [0001] The invention relates to the technical field of seabed abyss biological sampling, in particular to a device for trapping and maintaining pressure sampling of seabed abyss macro organisms. Background technique [0002] The development and utilization of marine biological resources are of great significance to scientific progress, economic construction, environmental governance and medical development. However, the biodiversity of marine living resources and the specific natural products they produce have just begun to come into people's field of vision. There are a large number of microorganisms and multicellular organisms in the ocean, and their great diversity has become a huge treasure house of biological natural products. However, only a few of the currently known natural products of marine organisms come from the deep sea. [0003] Due to the limitations of survey technology, the abyss is the most inaccessible environment for humans on earth, and...
