Full-sea-depth macro-organism pumping type fidelity collecting and storing system and collecting and storing method

Abstract

The invention discloses a full-sea-depth macro-organism pumping type fidelity collecting and storing system which comprises a pressure maintaining assembly, a sampling assembly, a circuit barrel, a culture kettle and a collecting barrel. The sampling assembly is inserted into the pressure maintaining assembly, and the sampling assembly is connected with the culture kettle. An inlet sealing assembly is arranged at an inlet in the middle of the pressure maintaining assembly, and the collecting barrel is connected with the pressure maintaining assembly through the inlet sealing assembly. A heat preservation assembly is bonded to the outer wall of the pressure maintaining assembly, a water pump and a pressure compensation device are arranged on the outer wall of the bottom of the pressure maintaining assembly, the pressure compensation device is communicated with the pressure maintaining assembly, and the water pump is communicated with the pressure maintaining assembly through a guide pipe. A temperature sensor and a pressure sensor are arranged on the inner wall of the pressure maintaining assembly. The circuit barrel is installed on the outer wall of the pressure maintaining assembly, a power source and a controller are arranged in the circuit barrel, and the controller is electrically connected with the temperature sensor, the pressure sensor, the heat preservation assembly andthe water pump. According to the invention, full-sea-depth macro-organism trapping and heat and pressure preservation culture can be realized, and the in-situ vital signs of the full-sea-depth macro-organisms can be effectively ensured.

Description

technical field [0001] The invention relates to the field of seabed biological collection, in particular to a pump-suction fidelity collection and storage system and a collection and storage method for whole-sea deep macrobiology. Background technique [0002] There are a wide variety of macrobiological resources and new biological species in the abyss of the whole sea (about 11,000 meters in deep water). Obtaining live macro organisms in the abyss of the whole sea is the key to carrying out changes in the environment of the abyss in the whole sea, life evolution process, and macrobiological species. The premise of scientific research such as the distribution of macro organisms and the living conditions of macro organisms. The characteristics of ultra-high pressure and low temperature present on the deep sea bottom of the whole sea make the existing macrobiological collection device return to the water surface due to the decrease of external pressure and the increase of exte...
