Underice detecting system applied to ice hole deployment and recovery, and deployment and recovery method of underice detecting system

Abstract

The invention relates to an underice detecting system applied to ice hole deployment and recovery. The underice detecting system can enter into underwater through an ice hole with limited hole diameter, and comprises a bearing cable used for being hung in the ice hole to uplift and down-put the underice detecting system, a converting and cable retracting device fixedly connected with the bearing cable driving the converting and cable retracting device to move and used for underwater retraction of a connection ROV, the connection ROV connected with the converting and cable retracting device toform a cylindrical whole structure moving in the ice hole with the limited hole diameter and can be separated from the converting and cable retracting device to collect water samples or sediments andconnected with an underice detecting AUV, and the underice detecting AUV used for being separated from the connection ROV to detect underwater or be connected with the connection ROV to carry out charging and data communication and capable of being fixed to the connection ROV to move along the connection ROV. According to the underice detecting system applied to ice hole deployment and recovery, detecting time and range underice can be improved, and the detecting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of marine technology engineering, and relates to an under-ice detection system suitable for deployment and recovery of ice holes and a deployment and recovery method thereof. Background technique [0002] At the Earth's poles there are ice packs and ice shelves that connect the oceans to the polar ice caps. The detection and sampling of the subglacial environment, including subglacial ocean thermohaline circulation observation, subglacial marine ecological environment detection, subglacial seawater and sediment sampling, etc. Important means, has important scientific significance. At present, there are mainly two ways to detect the sub-ice environment. One is to drill holes on the ice surface and put the instruments and equipment with cables into them. The instruments and equipment deployed in this way are limited to the detection of very limited areas under the ice holes. range, it is impossible to conduct large-sc...

Problems solved by technology

In this way, AUVs are usually deployed and recovered by digging through the ice layer and then deploying and recovering them in larger ice holes. However, the AUV's endurance is limited, resulting in limited detection time and range. In addition, thin ice layers can be used to open ice holes. However, for thick ice layers, such as ice shelves with a thickness of thousands of meters in the Antarctic region, holes are usually drilled by polar hot water drilling rigs, and the diameter of the opened ice holes is usually limited (in the order of 35cm to 80cm) , so it is impossible to directly deploy and recover AUVs in deep and narrow ice holes

[0003] Existing under-ice detection robots, such as a kind of under-ice detection robot published in patent number 201710886568.1, and a kind of under-ice detection robot published in patent number 201810313651.4, can only be detected by cutting through the ice layer and then AUVs are deployed and recovered in ice holes to achieve under-ice detection, and AUVs cannot be deployed and recovered directly in deep and narrow ice holes
