Description

Technical Field

[0001] This utility model relates to the field of tracker probes, and more particularly to a handheld tracker probe for underground coal mines. Background Technology

[0002] In coal mining, accurate measurement and recording of borehole trajectories are crucial for ensuring safe production, improving mining efficiency, and optimizing resource utilization. As a key piece of equipment for underground borehole measurement in coal mines, the performance of the tracker probe directly determines the accuracy and reliability of the measurement results. Traditional tracker probes typically use a fixed diameter design, which cannot adaptively adjust to the actual borehole diameter. This leads to friction or collisions with the borehole wall during the pushing process, affecting measurement accuracy and potentially damaging the equipment. Furthermore, the battery and measurement components of traditional tracker probes are usually separate, connected by connectors. This design increases the number of connection points and correspondingly increases the risk of malfunction. Utility Model Content

It is composed of the rear connector assembly, battery compartment assembly, control compartment assembly, and front compartment assembly connected in sequence to form a compact and fully functional whole. This not only ensures the tight fit between the components but also... Furthermore, the overall stability and reliability of the equipment are improved. Two flexible centralizers 15 are symmetrically installed at both ends of the probe body. Their main function is to maintain the stability and centering of the probe in the borehole, ensuring the accuracy of the measurement results. The flexible centralizers 15 can adaptively adjust their shape and size to adapt to boreholes of different diameters. This adaptive capability ensures that the probe remains concentric with the borehole during the pushing process, thereby reducing measurement deviation and improving measurement accuracy. The design of the centralizers allows the probe to remain stable in the borehole and is not easily affected by external factors. This helps to ensure the continuity and stability of measurement data, providing a reliable basis for subsequent data analysis. Due to the presence of the centralizers, the probe is less likely to rub or collide with the borehole wall during the pushing process, thereby reducing the risk of equipment damage.
