Underwater section detection buoyage

Abstract

The invention relates to an underwater section detection buoyage. The buoyage comprises a cable puller hinging ring, a temperature, salinity and pressure measuring sensor, a sensor protection cover, a buoyancy cabin, an underwater control unit, an inner oil bag, a direct current motor, an electric rotating valve, a check valve, a hydraulic motor, a rear end cover, an outer oil bag, an oil bag protection cover and a buoy watertight connector. The underwater section detection buoyage can be used for buoyancy conversion and lift control for performing temperature measurement, salinity measurement and depth measurement on sea water. The underwater section detection buoyage is connected with an ice-based buoyage by a high strength pulling cable device with seawater corrosion-resistant vulcanized joints for forming a shallow water type pull-type temperature, salinity and depth monitoring system in the Arctic Ocean. The underwater section detection buoyage is used for performing underwater temperature, salinity and depth section measurement with the measuring depth being 0-120m under the ice layer, so that the blank of being short of an observation method for 120m or shallower water in high seas internationally is filled, and the hydrological and meteorological simultaneous observation in the same region is realized; a lithium battery with ultra-large capacity is adopted for supplying power, so that the service life of the system is prolonged, and the underwater section detection buoyage can be applied to the field related to research in polar regions internationally.

Description

technical field [0001] The invention relates to an underwater profile detection buoy device, specifically a towed temperature, salt and depth monitoring system composed of an ice-based buoy and a high-strength towed cable (zero-buoyancy towed cable) device, which is directly used in shallow water in the Arctic Ocean. monitor. Background technique [0002] In recent years, the world's marine scientists have paid more and more attention to the characteristics of the Arctic and the Arctic Ocean marine environment and the impact of the Arctic ice and snow melting process on the climate. To engage in these researches, it is necessary first to obtain the data and changes of the temperature, salinity and depth of the Arctic and the Arctic Ocean marine environment, and to obtain these data requires corresponding observation and monitoring equipment. Meet the needs of Arctic scientific research. At present, the Woods Hole Oceanographic Institution in the United States has develope...

Meeting the needs of Arctic scientific research

At present, the Woods Hole Oceanographic Institution in the United States has developed a "cable fixed-point deep-water profile monitoring system", which measures depths from 100 meters to 4,000 meters underwater, and is used for large-depth ocean profile monitoring. This device has two problems : First, the device itself has a batter
