Rock temperature measuring device capable of protecting temperature measuring probe

Abstract

The invention discloses a rock temperature measuring device capable of protecting a temperature measuring probe, and the device comprises a tube body, a protection cover, a torsional spring, a battery, a switch, and the temperature measuring probe; the tube body comprises a bottom tube, a connection tube and a top tube, which are in cup joint through spring buckles; the protection cover consists of two symmetric arc-shaped covers; one end of each arc-shaped cover is movably connected to an end part of the top tube, and the other ends of the arc-shaped covers are connected through an electromagnet; the torsional spring is fixed at an end part of the top tube, and two ends of the torsional spring are respectively connected with the two arc-shaped covers; the temperature measuring probe is fixed at an end part of the top tube, and is located between the two arc-shaped covers; the battery and the switch are respectively disposed on the outer surface of the bottom tube, and the battery is connected with the electromagnet. According to the invention, the device can prevent the temperature measuring probe from colliding with a rock, and achieve purposes of protecting the temperature measuring probe and prolonging the service life of the temperature measuring probe.

Description

technical field [0001] The invention belongs to the technical field of mine temperature measurement, and in particular relates to a rock temperature measuring device capable of protecting a temperature measuring probe, which is mainly used for measuring the original temperature of a mine. Background technique [0002] The traditional mine rock shallow hole temperature measurement is to use blasting to drill a blasthole or a special temperature measurement hole (generally 1-2.5m in depth) in the working face that needs temperature measurement in the underground, and quickly send the thermocouple or semiconductor point thermometer probe to the hole. At the bottom, seal the temperature measuring hole with gun mud and other materials to measure the rock temperature at the bottom of the hole. Regardless of the roadway or the working face, after the rock formation is exposed, it is in contact with the air flow, and the original temperature field of the surrounding rock changes acc...

Problems solved by technology

However, in actual use, since the temperature measuring probe is fixed at the end of the latex tube, and the temperature measuring probe is not protected, when the temperature measuring probe is put into the hole, the temperature measuring probe is likely to collide with rocks, etc., which eventually leads to The temperature measuring probe is easily damaged, and the service life of the temperature measuring probe is low
