Cutting type in-situ fixing device of deep-sea mussels and other large organisms based on ROV, and fixing method thereof

Abstract

The invention relates to a cutting type in-situ fixing device of deep-sea mussels and other large organisms based on ROV, and a fixing method thereof. A fixed cabin and a driving oil cylinder are respectively installed on the ROV, the ROV provides hydraulic oil for the driving oil cylinder, one end of the fixed cabin is hermetically connected with a front cover, the other end of the fixed cabin ishermetically connected with a storage cabin, the other end of the storage cabin is hermetically connected with a back cover, a knife rest with a cutting knife is installed in the fixed cabin, and a delivery port is formed in the storage cabin; a rigid body is inserted into the storage cabin after passing through the back cover and is connected with one side of a piston, the other side of the piston is connected with a cutting knife pressing plate, and the piston is hermetically and slidably connected with the inner wall of the storage cabin; and a fixed solution is stored in a fixed solutionstorage bag, and the fixed solution storage bag communicates with the interior of the fixed cabin through a rubber tube passage. The cutting type in-situ fixing device provided by the invention meetsthe in-situ fixing needs of the mussels and other large organisms of a deep-sea ecosystem, is scarcely influenced by the sampling depth, high in corrosion resistance, large in storage volume, and flexible and stable to work, and can quickly and effectively fix large biological samples.

Description

technical field [0001] The invention belongs to the field of in-situ immobilization of large organisms such as deep-sea mussels, and specifically relates to an ROV-based in-situ immobilization device for large-scale organisms such as deep-sea mussels and a fixing method thereof. Background technique [0002] Due to the huge physical and chemical differences between the deep sea environment and the upper ocean environment, and it is difficult to complete sampling in a short period of time at a water depth of thousands of meters, the physiological state of organisms will undoubtedly undergo tremendous changes during the sampling process. The current sampling methods cannot truly reproduce the real state of the deep sea, which is the main bottleneck restricting the research of deep sea biology. The adaptive evolution of deep-sea organisms in extreme environments has produced a series of special natural product environmental stress coping mechanisms, which contain genetic resour...

AI Technical Summary

Problems solved by technology

The fixed equipment for large organisms is still in the pre-research stage, and there is no or very little precedent for development and application in China. The difficulty lies in the way of capturing large organisms, breaking them, fixing them, etc.

Moreover, the overall structure of the simple storage mechanism for microorganisms or large organisms is not suitable for ROV (remotely operated unmanned submersible) operations, and the immobilization effect of the organisms is not good.
