Abstract

The invention discloses a portable frozen soil active layer thickness and temperature detection device. The invention belongs to the technical field of geoscience, the device is composed of a data controller (1), an operating handle (2), unearthing screw (3), an exposed wire spring (6), an exposed wire ejector rod (7), a data connecting wire (8), a drill bit rod (9), an extension rod (10), a plurality of temperature and depth sensors (11), an integrated circuit board (12), a data connecting wire connector (14), a supporting plate baffle (15), a supporting plate clamping ring (16), a supportingplate (17), and fixing bolts (22), connectors (31) and grasp enhancing sleeves (32). The device is characterized in that the outer surfaces of the operation handle (2), the extension rod (10) and thedrill bit rod (9) are respectively provided with the unearthing screw (3), the temperature and depth sensors (11) are fixed on the inner surfaces of the walls of the extension rod (10) and the drillbit rod (9), and the hair-touching temperature-conducting core (30) is a copper wire or silver wire. The device is simple in preparation, high in operability, low in cost and obvious in effect.

Description

technical field [0001] The invention relates to a portable permafrost active layer thickness and temperature detection device, which belongs to the field of geographic science and technology. Background technique [0002] The permafrost active layer refers to the layer of soil that melts in summer and freezes in winter over the permafrost. It has the characteristics of one-way melting in summer and two-way freezing in winter. The active layer of permafrost and its changes have an important impact on water and heat exchange between the ground and air, surface hydrological processes, landform processes, ecosystems in cold regions, engineering buildings and their operations in cold regions, etc. Therefore, the monitoring and research of the active layer of permafrost has always been one of the core issues of geocryology research, mainly including the following three aspects: long-term monitoring of the active layer under natural or engineering activity conditions as an importa...

AI Technical Summary

Problems solved by technology

From the above existing technologies, it can be seen that there are still many problems in the research on the detection device of the active layer of permafrost, especially the environment in the area where the permafrost is located is generally relatively harsh, which is not suitable for operators to work for a long time, and many large-scale operating machines are also difficult to drive In the working area, the permafrost becomes extremely hard because the water in it freezes into ice. If it is close to the iron drill, it is difficult to quickly insert the detection device into the permafrost, especially in winter operations.
