Abstract

The invention relates to an organism capturing device, and aims to provide a pressure-maintaining capturing device for deep-sea large organisms. The device comprises a pressure maintaining cabin body, a movable end cover, an end cover releasing mechanism, an end cover closing mechanism and an energy accumulator system; a fixed end cover with a hole in the center is arranged at the open end of the pressure-resistant cylinder, and a movable end cover matched with the fixed end cover is located in the pressure-resistant cylinder; the movable end cover is controlled by an end cover releasing mechanism and an end cover closing mechanism, and when capturing of the deep-sea large organisms is completed, linear motion provided by the spring is converted into space translation and rotation motion of the movable end cover, so that sealing between the movable end cover and the pressure-resistant cylinder is achieved. According to the invention, a multi-connecting-rod mechanism is adopted, so that the spatial translation and rotation of the movable end cover can be realized, and a large opening is provided to realize the capture of organisms with larger volume; the position of the movable end cover is accurately controlled while self-tightening sealing is achieved. A motor, an oil cylinder and a transmission structure in the prior art are omitted, the overall structure can be simplified, cost is saved, and stability is guaranteed.

Description

technical field [0001] The invention relates to a biological capture device, in particular to a pressure-maintaining capture device for deep-sea large organisms. Background technique [0002] So far, most deep-sea organisms (relative to microorganisms) sampling equipment are non-pressure-holding (such as trawl nets, fishing cages, etc.). Due to the huge pressure difference between atmospheric pressure and deep-sea hydrostatic pressure, many deep-sea organisms will be lost due to The pressure is severely damaged, so it is of great significance to carry out pressure-holding sampling. [0003] The traditional pressure-holding sampling technology uses a high-pressure ball valve to seal. The high-pressure ball valve is usually made of stainless steel, and its weight increases with the increase of the diameter, which will bring great inconvenience to the deployment of deep-sea equipment. In addition, the ball valve uses the through hole in the center of the ball as the biological...
