Blue hole three-dimensional scanning and environment monitoring system

Abstract

The invention discloses a blue hole three-dimensional scanning and environment monitoring system. The system comprises a data acquisition system and an underwater three-dimensional panoramic imaging sonar system, wherein the data acquisition system comprises a first self-weight anchor, a cable, a first floating ball, at least one ocean element sensor, a temperature-salinity-depth section plotter and an acoustic Doppler flow velocity section plotter; and the underwater three-dimensional panoramic imaging sonar system comprises a second self-weight anchor, a guide rail supporting column, a hanging bracket, a hanging rope and a sonar assembly. The blue hole three-dimensional scanning and environment monitoring system is simple and reasonable in structure and convenient to install and use. The blue hole environment element data can be dynamically monitored for a long time, and comparative research is facilitated. The blue hole form scanning field work is low in cost and easy to realize.

Description

technical field [0001] The invention relates to the technical field of blue hole detection equipment, in particular to a blue hole three-dimensional scanning and environmental monitoring system. Background technique [0002] Oceanic blue holes are karst caves that exist on the bottom of the sea. The discovered oceanic blue holes are generally located in shallow sea water, and the water depth around the hole is much shallower than the water depth inside the hole. Therefore, the blue hole shows a different dark blue color from the surrounding waters when viewed from the sea surface. , the deepest oceanic blue hole that has been discovered in the world so far is the Yongle Blue Hole in Xisha, my country, with a depth of more than 300m. The more famous blue holes in the world include Deans Blue Hole in Long Island, Bahamas, Hadab Blue Hole in Egypt, and the Great Blue Hole in Belize, Honduras. , Gozo Blue Hole, Malta, etc. [0003] The cause of the oceanic blue hole may be relate...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, underwater robots are usually equipped with surveying and mapping equipment to survey and map the shape of blue holes, and underwater robots are equipped with hydrological element survey equipment and various sensors to obtain hydrological elements, water quality data, and environmental element data. This method has high costs. , the observation time is short, and it cannot be monitored dynamically for a long time.
