A kind of seismic monitor in mining area

Abstract

A seismic monitoring instrument for mining areas, including a standpipe. The upper part of the standpipe is provided with an upper annular partition. An annular electromagnet is fixedly installed on the bottom side of the upper annular partition. The bottom side of the annular electromagnet is provided with an annular metal plate. The annular electromagnet The bottom side of the iron can electromagnetically absorb the top side of the annular metal plate. A left-right symmetrical strip chute is provided on the upper part of the inner wall of the vertical pipe. There are sliders in the strip chute, and the sliders can move along the corresponding strip chute respectively. Sliding up and down, the slide blocks are fixedly connected to the annular metal plate respectively. The bearing on the bottom side of the annular metal plate is connected to the upper end of the externally threaded pipe. A driving device that can rotate the externally threaded pipe is fixedly installed on the bottom side of the annular metal plate. The outer circumference of the vertical pipe is A left-right symmetrical strip-shaped through groove is provided in the middle. The upper part of the strip-shaped through-groove is hingedly connected to the upper end of the support rod. The upper part inside the support rod is hingedly connected to one end of the upper end of the connecting rod. The lower end of the outer periphery of the externally threaded pipe is threaded to install a nut. The invention has simple structure and ingenious conception.

Description

technical field [0001] The invention belongs to the field of monitoring instruments, in particular to an earthquake monitoring instrument for mining areas. Background technique [0002] Surface and shallow seismic monitoring has been greatly affected in mining areas due to surface mining and underground mining. In order to conduct effective base monitoring in mining areas, underground seismic monitoring is generally used, and the seismometer is placed in the well and directly connected to the bedrock of the observation well. Rigidly connected together, the existing well lock fixing device cannot release the well lock when the power is cut off, so that the underground monitoring equipment cannot be taken out. At the same time, it is difficult to level and adjust the seismometer because it is placed underground If the seismometer works at an inclination of 2°, its performance will deteriorate, and it will not be able to perform effective monitoring and meet the actual needs.

[0002] Surface and shallow seismic monitoring has been greatly affected in mining areas due to surface mining and underground mining. In order to carry out effective base monitoring in mining areas, underground seismic monitoring is generally used, and the seismometer is placed in the well and directly connected to the bedrock of the observation well. Rigidly connected together, the existing well lock fixing device cannot release the well lock when the power is cut off, so that the underground monitoring equipment cannot be taken out. At the same time, it is difficult to level and adjust the seismometer because it is placed underground. If the seismometer works at a tilt of 2°, the performance will be poor, and it will not be able to monitor effectively and meet the actual needs. Therefore, we have invented a seismic monitor for mining areas.
