Sensor screw lifting mechanism for ocean buoy monitoring system

Abstract

The invention relates to a sensor screw lifting mechanism for an ocean buoy monitoring system. A lifting motor is fixed on a supporting body; an output shaft of the lifting motor is connected with theupper end of a lifting screw through a universal coupling; the lower end of the lifting screw is rotationally assembled with a screw guide cylinder; a three-jaw bracket extends out of the periphery of the screw guide cylinder; one jaw of the three-jaw bracket passes through two through holes positioned on the same line at the lower part of a three-way pipe; the upper end of a circular guide rod is fixedly connected with the supporting body, and the lower end of the circular guide rod is inserted into a through hole in the upper part of the three-way pipe; a sensor bracket is in screw-thread fit with the lifting screw; the circular guide rod penetrates through the sensor bracket; the lifting screw and the circular guide rod are parallel to each other; under limitations of the circular guide rod and the three-way pipe, the lower end of the lifting screw can slightly swing. According to the screw lifting mechanism disclosed by the invention, the underwater monitoring time of the sensor is controlled, so that the attachment condition of organisms to the sensor is reduced, and the sensitivity of the sensor detection data is improved.

Description

technical field [0001] The invention relates to a marine buoy monitoring system, in particular to a spiral lifting mechanism for a sensor of the marine buoy monitoring system. Background technique [0002] Buoy monitoring is the main method of marine water quality monitoring and aquaculture monitoring in my country. In view of the long-term underwater characteristics of the sensor, there is a big problem with the sensitivity of the sensor probe. Maintaining the cleanliness of sensor probes is a key factor for the accuracy of water quality parameter monitoring data. Due to the variety of microorganisms and shellfish in seawater, the adhesion of organisms to sensors often leads to reduced accuracy or even damage to sensors, thus losing the meaning of monitoring. The maintenance methods of the existing fixed suspension sensors: artificial periodic cleaning, underwater ultrasonic cleaning, special material coating, etc. are mainly handled by physical and chemical methods. In th...

AI Technical Summary

Problems solved by technology

Although the existing physical and chemical maintenance methods can improve the adhesion to a certain extent, they still cannot achieve the expected cleaning effect

[0003] In the prior art, there is also a marine buoy monitoring system that enables the sensor to realize the lifting function, but the rigidity requirements of the entire device are relatively high, and the structure is relatively complicated, resulting in relatively high cost and greatly reduced application range
