Problems solved by technology

The observation base station is located on the bottom of the deep sea, and the energy supply is relatively difficult; it needs to be able to work for a long time (about 1 year); therefore, the power consumption of the sampler should not be too large
[0005] The seawater sampler currently used only has the function of seawater sampling. The seawater will also release a large amount of energy during the process of depressurization sampling. This energy is consumed by the throttling loss of the water inlet of the sampler and turned into heat.
The pressurized discharge of wastewater needs to be completed by another device, which consumes a lot of power

Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. And the features in the embodiments can be combined with each other.

[0025] The core of the present invention is to provide an energy-saving seawater sampler for in-situ detection of deep-sea seawater, which can utilize the energy released during seawater depressurization and directly use it for pressurized discharge of waste water, greatly reducing the power of the deep-sea seawater sampler Consumption, so that the sampler can meet the requirements of long-term monitoring of physical and chemical parameters of deep sea water.

[0026] Such as figure 1 As shown, the deep-sea seawater in-situ detection energy-saving seawater sampler of the present invention comprises a pressure-resistant shell 11, a detection instrument 6,...

Abstract

The invention discloses an energy-saving seawater sampler for deep-sea seawater in-situ detection and an operating method of the energy-saving seawater sampler. The energy-saving seawater sampler for deep-sea seawater in-situ detection comprises a pressure-resistant shell, wherein a detection instrument and a wastewater pool are arranged in the pressure-resistant shell; a water inlet and a water outlet are formed in the pressure-resistant shell, the water inlet and the water outlet are respectively communicated with the wastewater pool through a water inlet pipeline and a water outlet pipeline; the sampler also comprises a proportional throttling valve, a servo motor, a step-down motor, a variable pump and a one-way valve; the proportional throttling valve, the step-down motor and the detection instrument are sequentially connected to the water inlet pipeline in series; the detection instrument is positioned at one end, which is close to the wastewater pool, of the water inlet pipeline; the variable pump and the one-way valve are connected in series on a drainage pipeline; an output shaft of the step-down motor and an input shaft of the variable pump are in transmission connection; an output shaft of the servo motor and an input shaft of the variable pump are in transmission connection. The power consumption of the deep-sea seawater sampler can be greatly reduced, so that the sampler can meet the requirement of long-term monitoring for physical and chemical parameters of the deep-sea seawater.

Description

technical field [0001] The invention relates to a sampler for in-situ detection of deep seawater physical and chemical parameters and a working method thereof. Background technique [0002] At present, based on the urgent need for marine scientific research for seabed observation, in recent years, countries around the world have proposed their own seabed observation network plans and invested heavily in the construction of their own long-term seabed observation network. The submarine observation network is composed of many observation base stations, and each base station is mainly composed of a pressure-resistant shell and related testing instruments inside the shell. In-situ detection of seawater-related physicochemical parameters (such as anion, salinity, methane and dissolved oxygen concentration, etc.) is one of the functions that every base station must have. [0003] The pressure of seawater outside the pressure hull of the observation base station is strong, for exam...
