Descriptions A Kind of Conductivity-Temperature-Depth System Based on 3D Printing Technology Technical Field The utility model belongs to the technical field of ocean exploration instruments, and relates to a conductivity-temperature-depth system based on 3D printing technology.
Background Technology The study of physical oceanography cannot do without a large amount of measured ocean data. Ocean survey is the most direct and effective method to obtain real-time ocean data. The integration of various sensors and instruments with excellent performance is the foundation of ocean survey in the field of ocean research. Among them, conductivity, temperature and depth are the basic ocean hydrological elements, and are the most important measurement parameters in ocean resources exploration, ocean water quality analysis and other activities.
Before the appearance of the integrated measuring instrument for parameter measurement, the sub-measurement method was used for ocean resource exploration and ocean water quality analysis, which means that the data we need were obtained separately, consuming a lot of time and energy, and the obtained data were unreliable [23]. Later, the appearance of conductivity-temperature-depth system completely replaced the traditional measuring method, which can measure and read the ocean parameters in real time to avoid the lag of data. Existing conductivity-temperature-depth systems all adopt "material reduction" manufacturing technology and assembly method, which have defects in protection structure, pressure resistance and other aspects, and cannot well meet the application requirements of ocean sampling conductivity-temperature-depth field measurement.
Content of Utility Model The utility model aims to overcome the defects of the prior art and provide a conductivity-temperature-depth system based on 3D printing technology.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a conductivity-temperature-depth system based on 3D printing technology comprises a temperature sensor, a conductivity sensor, a pressure sensor and a control mainboard, wherein the temperature sensor, the pressure sensor and the conductivity sensor are all connected with the control mainboard through wires, and the conductivity sensor comprises a conductivity sensor packaging shell, a conductivity probe, a temperature compensation circuit board and a locking device; The temperature sensor and the pressure sensor comprise a sensor packaging shell, a sensor and a locking device; The control mainboard of the probe is fixed in the proof pressure second zone of the cabin body; The cabin body comprises a proof pressure shell, a fixed flange, a support flange and a support plate.
Further, the conductivity sensor comprises a conductivity sensor packaging shell, a conductivity probe and a temperature compensation circuit board, and is self-contained.
Further, the non-support flange is provided with three hole sites for installing conductivity sensors, temperature sensors and pressure sensors, which are installed at the head position of the cabin body and are hermetically installed to form a proof pressure zone.
Further, the cabin body comprises a proof pressure shell, a fixed flange, a support flange and a support plate, and the interior comprises a water inlet, a test cabin, a proof pressure first area and a proof pressure second area, wherein the proof pressure second area is positioned on the end cover. The test chamber is used for storing seawater, and the three probes of the conductivity sensor, the temperature sensor and the pressure sensor are placed here.
The conductivity-temperature-depth system of the utility model improves the measuring accuracy of the conductivity sensor by utilizing the horizontal cross section thermistor and the pressure sensor inside the conductivity sensor probe. The water inlet adopts a net structure, which has the effect of a filter screen and reduces the influence of seawater impurities on sensor measurement. The conductivity-temperature-depth system has the capability of long-term real-time measurement, can store measurement data in real time, can be used as measuring equipment of related platforms such as underwater gliders, and has important significance for improving the data quality of the conductivity-temperature-depth sensor.
