Earthquake monitor for mine region

Abstract

The invention relates to an earthquake monitor for a mine region. The monitor comprises a vertical tube, an upper annular separator plate is arranged in the upper portion of the vertical tube, an annular electromagnet is fixedly mounted in the bottom side of the upper annular separator plate, an annular metal plate is arranged in the bottom side of the annular electromagnet, the bottom side of theannular electromagnet can electromagnetically attracts the top side the annular metal plate, bar-shaped chutes in left-right symmetry are formed in the upper portion of the inner wall of the verticaltube, slide blocks are arranged in the bar-shaped chutes respectively, can slide up and down along the corresponding bar-shaped chutes, and are fixedly connected with the annular metal plate, the bottom side of the annular metal plate is in bearing connection with the upper end of an outside threaded tube, a driver which can enable the outside threaded tube to rotate is fixedly mounted in the bottom side of the annular metal plate, bar-shaped through grooves in left and right symmetry are formed in the middle portion of the periphery of the vertical tube, the upper portions of the bar-shapedthrough grooves are hinged to the upper ends of support rods respectively, the inner upper portion of each support rod is hinged to one end of the upper end of one corresponding connecting rod, and anut is mounted in the lower end of the periphery of the outside threaded tube in a treaded way. The earthquake monitor for the mine region is simple in structure and ingenious in 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.
