A deep-sea biological outboard thermal insulation device

Abstract

The invention relates to a deep-sea organism outboard heat preservation device. The deep-sea organism outboard heat preservation device comprises a pressure-proof inner shell, and the pressure-proof inner shell is internally provided with a cavity. A pressure-proof enclosure bulkhead is connected to the pressure-proof inner shell, wherein the pressure-proof enclosure bulkhead is in a barrel shape and communicates with the cavity. A hatch cover is connected to the outer side face of the pressure-proof enclosure bulkhead, and an electric balance valve is mounted on the hatch cover. A pressure-proof outer cabin is arranged outside the pressure-proof inner shell, and a closed cavity is formed by connecting a first pressure-proof outer shell and a second pressure-proof outer shell through a flange. The side, close to the hatch cover, of the first pressure-proof outer shell is fixedly connected to the pressure-proof enclosure bulkhead. A water inlet cabin penetration part and a water outlet cabin penetration part are mounted on the second pressure-proof outer shell in a spaced manner. A circulating water pump is mounted in a gap formed between the inner wall of the pressure-proof outer cabin and the outer wall of the pressure-proof inner shell. An input end pipe of the circulating water pump is connected with the water inlet cabin penetration part, and an output end pipe is connected with multiple semiconductor refrigeration assemblies arranged on the outer wall of the pressure-proof inner shell in the circumferential direction. The semiconductor refrigeration assemblies are connected with the water outlet cabin penetration part through pipes and electrically connected with a control system in a submersible cabin. By means of the deep-sea organism outboard heat preservation device, the automation degree is raised, and the in-situ fidelity is improved.

Description

technical field [0001] The invention relates to the technical field of heat preservation devices, in particular to a deep sea biological outboard heat preservation device used in deep seas that can maintain the temperature of biological samples collected in deep sea for a long time. Background technique [0002] Existing manned submersibles or deep-sea sampling equipment are not equipped with devices that can preserve the temperature of collected samples for a long time, and most of the samples collected by ROV use cold storage materials for short-term and inaccurate sample temperature preservation; An insulated cabinet for long-time refrigeration cannot be used in a high-pressure deep-water environment. Conventional compression refrigeration technology has complex systems, takes up a lot of space, and has poor safety in deep water, so it is not suitable for deep-sea biological heat preservation devices. Contents of the invention [0003] Aiming at the shortcomings in the...
