Problems solved by technology

Deep-sea sampling technology is an essential means for studying hydrothermal fluids. At present, the most commonly used sampling equipment is triggered by hydraulic pressure, but the hydraulic trigger method cannot work independently, and requires the cooperation of manipulators and hydraulic cylinders. There will be vibration of the sampling tube, which will cause the surrounding seawater to mix

Abstract

The invention relates to an electric deep-sea hydrothermal pressure-maintaining sampler. The existing product is not compact enough in structure. The electric deep-sea hydrothermal pressure-maintaining sampler comprises a sampling pipe, a sampling valve, an electronic control driver and a sampling barrel, wherein the electronic control driver comprises a driver cavity, a circuit cavity and a transmission screw rod which are arranged in a coaxial way; a motor is fixedly arranged in a sleeve; the sleeve is movably connected with the driver cavity, can move axially, but can not rotate; two limit switches are respectively arranged at the two ends of the motor; one end of the transmission screw rod is fixedly connected with a motor shaft in a coaxial way, and the other end of the transmission screw rod is connected with the end part of a sampling piston of the sampling valve; the sampling barrel comprises a sampling cavity, an energy storage cavity, a connector and an inflation valve body which are arranged in a coaxial way; one end of the sampling pipe is connected with a liquid inlet of the sampling valve; a liquid outlet of the sampling valve is connected with a liquid inlet through hole of the sampling cavity. A trigger mechanism of the electric deep-sea hydrothermal pressure-maintaining sampler is simple in structure and high in action reliability; the electric deep-sea hydrothermal pressure-maintaining sampler has the characteristics of being simple and convenient to control, reusable and the like, thus being suitable for the operation of a mechanical arm of a deep submergence vehicle.

Description

technical field [0001] The invention relates to an electric deep-sea hydrothermal pressure-maintaining sampler, in particular to a deep-sea hydrothermal pressure-maintaining sampler which uses a motor-driven mode to control a sampling valve. Background technique [0002] The deep sea is one of the hot research focuses of scientists from all over the world today. There are a large number of mineral resources near hydrothermal vents and the characteristics of biological communities in extreme environments, making them of great scientific research value. Deep-sea sampling technology is an essential means for studying hydrothermal fluids. At present, the most commonly used sampling equipment is triggered by hydraulic pressure, but the hydraulic trigger method cannot work independently, and requires the cooperation of manipulators and hydraulic cylinders. There will be a vibration of the sampling tube, which will cause the surrounding seawater to mix in. At present, there are al...
