Automatic section observation system of under-ice sea

Abstract

The invention relates to a section observation equipment, in particular to an automatic section observation system of a polar under-ice sea, comprising an observation equipment arranged below an ice surface, a program control winch and a storage battery, wherein the program control winch and the storage battery are arranged above the ice surface, the storage battery is connected with a wind-solar hybrid power generating device through a power supply controller so that the storage battery can acquire a continuous power supply, the program control winch is connected with the observation equipment through a mooring rope, one end of the mooring rope is wound in the program control winch, the other end of the mooring rope is backwards connected with the observation equipment through a pully, the pully is provided with a photoelectric encoder with the counting function, the mooring rope is a nylon mooring rope, the program control winch comprises a mooring rope retracting part and a control part, the mooring rope retracting part of the program control winch comprises an electromagnetic induction direct-current motor, and the electromagnetic induction direct-current motor is connected with the storage battery through the power supply controller. The automatic section observation system of the polar under-ice sea has simple structure and low manufacturing cost, long-term continuous observation can be realized, and the observation efficiency is good.

Description

technical field [0001] The invention relates to a profile observation device, in particular to an automatic profile observation system for the polar subglacial ocean. Background technique [0002] Observing ocean profiles on polar ice floes is of great significance. In recent years, sub-ice buoys and Ice-Tethered Profiler (ITP) have been deployed abroad in the Arctic. During the International Polar Year, marine scientific research units in the United States, Canada, Japan and other countries deployed moored submersible buoys with profilers and ice-based ocean automatic profiling system observation equipment on a large scale in the Arctic Ocean, and obtained a large number of sub-ice ocean However, there is no mature automatic profile observation system for polar subglacial oceans in China. [0003] At present, the more common ITP includes a buoy above the ice surface and a profile measurement device below the ice surface. The buoy is connected with a weight through a cable ...

AI Technical Summary

Problems solved by technology

Therefore, the existing ITP has a complex structure, and has very high requirements on the materials and manufacturing process of each component, which greatly increases the manufacturing cost

ITP's underwater profile measurement device is equipped with a battery that powers the motor. The battery cannot be replaced or recharged. After the battery is exhausted, the motor cannot be started, and the profile measurement cannot be continued.
