Self-floating deep-sea organism sampling device

Abstract

The invention relates to a self-floating deep-sea organism sampling device. The device comprises a buoyancy material shell, a ball storage hole is formed in the center, a sample channel is formed in the middle of the upper portion of a body and communicated with the ball storage hole, a beacon hole is formed in the portion, located on one side of the sample channel, of the body, and an oxygen cabin hole is formed in the bottom of the ball storage hole. A plurality of water permeable holes are evenly distributed in the circumferential direction of the body, each water permeable hole penetrates through the ball storage hole, anchoring notches are formed in the two sides of the bottom of the body respectively, and mounting base holes are further formed in the anchoring notches. A beacon is mounted in a beacon hole, a ball storage cabin is mounted in the ball storage hole, a high-pressure oxygen cabin is mounted in the oxygen cabin hole, mounting bases are matched with the mounting base holes, the mounting bases are welded to the spherical outer wall of the storage ball cabin, a gravity anchor is fixed to the bottom of each mounting base through an explosive bolt, and the gravity anchors are located in the anchoring notches. An automatic opening and closing cabin opening cover is mounted on the top surface of the ball storage cabin. A driving control cabin is arranged at the bottom in the ball storage cabin, so that the work is reliable.

Description

technical field [0001] The invention relates to the technical field of deep-sea sampling tools, in particular to a self-floating deep-sea biological sampling device. Background technique [0002] In recent years, marine biologists have made real-time observations of deep-sea organisms through deep-sea submersibles, such as the Jiaolong manned submersible or a cable-controlled robot (ROV), and conducted valuable microbial and macrobiological samples through the bow of the deep-sea submersible. The onboard manipulator carries out deep-sea sampling, and collects and stores it through the sampling basket fixed on the bow tray, so as to facilitate laboratory observation, cultivation and research after landing. To complete the sampling of deep-sea organisms through deep-sea submersibles, it is often necessary to rent large-tonnage surface mother ships for the deployment and recovery of submersibles. Under such circumstances, it is very likely to cause the loss of the deep-sea sub...

Problems solved by technology

To complete the sampling of deep-sea organisms through deep-sea submersibles, it is often necessary to rent a large-tonnage surface mother ship for the deployment and recovery of submersibles. On the one hand, this involves many support personnel and costs a lot of money. Under such circumstances, it is very likely to cause the loss of the deep-sea submersible or an accident
