Jiaolong manned submersible extensible deep-sea biocapture

Abstract

The invention relates to a biological trap, in particular to a Jiaolong manned submersible extensible deep sea biological trap. The utility model comprises a collecting membrane, a main support rod, amain shell, an inner support cylinder, an operation motor and an outer feed pump; The outer side of the collecting film is connected to the inner side of the main supporting rod, and the rear part isadhered to the front surface of the main case; the front part of the main supporting rod is connected to the support frame; the hinge seat of the front surface of the main case is connected to the rear part; the inner supporting cylinder is installed at the front part of the feed screw; and the output shaft of the operating motor is installed with an operating gear. The present invention utilizesan expansion mechanism to increase the size of the trap to quickly capture biological samples, and assists in capturing and releasing biological samples by spraying water. The invention has the advantages of simple overall structure, convenient operation, quick and flexible completion of biological sample capture, flexible contact with the biological sample to reduce damage, larger adaptability due to the extensible shrinkage of the overall structure, convenient for rapid, repeated use, storage and transportation.

Description

technical field [0001] The invention relates to a biological trap, in particular to an extendable deep-sea biological trap for the Jiaolong manned submersible. Background technique [0002] Biotrap is one of the important tools for obtaining biological samples from the seabed. The analysis of biological samples obtained from the deep sea is of great significance to the research of marine ecosystems, biogeography, biogenetics, biodiversity and community distribution. Previously, trawling was the most common method of capturing seabed organisms, but this method could only obtain incomplete biological samples. At present, my country's "Jiaolong" manned submersible has obtained some relatively complete biological samples (such as sea cucumbers, sea urchins, sponges, sea anemones, fish, shrimp, etc.) Limitations: Jiaolong’s subsea operation is not efficient in catching organisms, which not only wastes a lot of subsea operation time, but also causes a certain degree of damage to t...
