Microseismic detection sensor applicable to undersea deep high-corrosive environments

Abstract

The invention relates to a microseismic detection sensor applicable to undersea deep high-corrosive environments. The microseismic detection sensor is mainly formed by connecting an outer anticorrosion shell, an upper cover, an inner metal shell, an upper connecting post, a lower connecting post, a PVC (polyvinyl chloride) plastic separator, a seismometer core and a lower cover. The outer anticorrosion shell, the upper cover and the lower over are all made of polyethylene plastic. The inner metal shell, the upper connecting post and the lower connecting post are all made of seamless steel tubes. By the use of the microseismic detection sensor, the defect that the prior instrument applied to rich-wash high-corrosive environments has poor water resistance and corrosion resistance is overcome; the microseismic detection sensor is available for long-term stable reliable application in undersea deep high-corrosive environments. The microseismic detection sensor is available for popularization and application in microseismic monitoring for water conservancy, slope engineering and tunnel engineering and is especially suitable for application in rich-water mines and undersea mines.

Description

technical field [0001] The invention relates to mine safety monitoring, in particular to a micro-seismic pickup sensor suitable for high corrosion environment in deep sea. Background technique [0002] Microseismic monitoring technology is a multidisciplinary interdisciplinary technology involving mining, geophysics, computer technology, communication technology, etc. It has been gradually applied to the monitoring and early warning of mine dynamic disasters this year. The microseismic monitoring sensor is an important part of the microseismic monitoring system and has the function of receiving shock waves. At present, microseismic monitoring uses common microseismic sensors which generally consist of sensor cores, fixtures and housings. This kind of ordinary sensor is generally waterproof and has poor corrosion resistance, especially in the high corrosive environment with high concentration of inorganic salts in the deep sea, the anti-corrosion ability cannot meet the dail...

AI Technical Summary

Problems solved by technology

[0004] 1. The waterproof performance is average when used in a water-rich environment;

[0005] 2. In a highly corrosive environment, especially in a highly corrosive environment where the high concentration of inorganic salts in the deep sea leads to high ion concentration, the ordinary anti-corrosion design of the sensor cannot meet the daily production needs, and the sensor shell will be damaged during long-term use. Corrosion affects the monitoring accuracy and even leads to the destruction of the sensor, making it impossible to monitor at all
