Problems solved by technology

At present, the method of drilling holes to measure the thickness of sea ice at home and abroad is to use screw drilling tools to drill holes on the sea ice. After drilling through the sea ice, a special ice ruler is used to measure the thickness of sea ice. Low efficiency brings great inconvenience to field work

Abstract

The invention discloses a drill tool and a method for measuring the thicknesses of sea ice and river ice while drilling. The drill tool comprises a display, a detection control unit, a direct-current motor, a screw drill pipe, a drill bit and a storage battery. A PLC (programmable logic control) module is integrated inside the detection control unit and can collect data measured by a torque sensor and a laser distance measuring instrument, and the drilling torque of the drill pipe and the thickness of an ice layer can be displayed via the display on the upper side of the detection control unit. The drill tool and the method have the advantages that drilling machines and tools can be effectively combined with measurement-while-drilling and automatic detection control measures, the data of the thickness of the sea ice can be acquired in a drilling procedure and can be displayed via the display, accordingly, the sea ice and river ice thickness measuring efficiency is greatly improved, and the labor intensity is reduced; the data are acquired and processed by the PLC module, and sudden change values can be adjusted according to different properties of ice of different regions, so that the detection method is excellent in practicality and applicability when applied to large regions.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a sea ice thickness measuring drilling tool used for measuring the thickness of shallow ice such as sea ice and river ice while drilling. Background technique [0002] Sea ice is an important part of polar oceans, and it is the product of the joint action of surface heat budget and ocean heat flux. Therefore, the growth and melting of sea ice has an important impact on climate change. While sea ice thickness is an important climate parameter and must be accurately represented in numerical models of the global climate system, it is one of the most difficult geophysical parameters to measure. Sea ice thickness controls the exchange of heat, moisture, and momentum between the ocean and atmosphere to affect global climate. Long-term changes in sea ice cover and its thickness distribution are sensitive indicators of global climate change. [0003] In addition, in the development of marine engineer...
