AI Technical Summary

Technical Problem

The existing deep-sea biofidelity sampling system cannot effectively compensate for dissolved oxygen in the sample compartment, resulting in organisms dying due to insufficient oxygen during the sampling process.

Method used

A sampling dissolved oxygen compensator is designed, which uses the aeration membrane assembly and deep-sea pump assembly in the gas exchange chamber to dissolve oxygen into seawater through the aeration membrane spiral tube, and transports the compensated seawater to the sample through the deep-sea pump assembly. Inside the cabin, ensure the balance of dissolved oxygen.

Benefits of technology

It effectively increases the dissolved oxygen concentration in the sample chamber and significantly improves the survival rate of deep-sea organisms. The design of the system ensures its stable operation in high-pressure environments.

Abstract

The present invention proposes a dissolved oxygen compensator and method for a fidelity sampling system of abyssal amphipods, belonging to the field of fidelity sampling of deep-sea organisms. The invention solves the problem that the traditional fidelity sampling system of deep-sea organisms cannot compensate for dissolved oxygen. A sampling dissolved oxygen compensator comprises: a gas exchange chamber, in which an aeration membrane assembly and a deep-sea pump assembly are sealed and arranged, the deep water pump inlet of the deep-sea pump assembly passes through the outer wall of the gas exchange chamber and is connected to the sample chamber, the deep water pump outlet of the deep-sea pump assembly is connected to the inlet end of the aeration membrane assembly, the aeration membrane assembly is used to unidirectionally dissolve the oxygen in the gas exchange chamber into the seawater flowing in the aeration membrane assembly, and then transport the seawater to the sample chamber under the pumping action of the deep-sea pump assembly; a pressure balance chamber, a second piston separates the pressure balance chamber into a first chamber and a second chamber, the first chamber is connected to the gas exchange chamber, and the second chamber is connected to the sample chamber. It is mainly used for compensation of dissolved oxygen during deep-sea sampling.
