A working protection device for blasting vibration sensor

Abstract

The invention relates to a working protection device for a blast vibration sensor, and belongs to the field of safety protection of sensors. The device comprises an outer protective layer, an outer protective cover, a side energy consumption ring, a top energy consumption ring, an inner protective cover, filling particles, a shock-insulation supporting seat and a sensor connection hole. When blasting occurs, blasting gravels and dust generated by the blasting are directly obstructed by an outer rubber protective layer, generated larger blasting flying stones and blasting shock wave are blockedby the outer protective layer, the outer protective cover, the side energy consumption ring, the top energy consumption ring, the inner protective cover and the filling particles together, vibrationtransmitted into the ground is reduced through the shock-insulation supporting seat, and the device is prevented from absorbing the vibration of the ground to affect the monitoring. The working protection device for the blast vibration sensor can resist the pressure waves and vibration waves in the blasting shock waves and the impact of the blasting flying stones, can protect the sensor and ensurethe smooth progress of the blasting monitoring.

Description

technical field [0001] The invention relates to a working protection device for a blasting vibration sensor, which belongs to the field of sensor safety protection. Background technique [0002] The blasting vibration generated by blasting projects and urban demolition blasting projects will cause varying degrees of damage to surrounding buildings, which will lead to deformation, partial cracking, and even collapse of surrounding existing buildings, and even endanger the personal and property safety of residents. . The safety criterion of blasting vibration wave blasting project is related to the safety of the surrounding existing buildings and the safety of residents' personal and property safety. The blasting sensor can monitor the ground vibration information around the blasting project and provide data support for the safety assessment of the blasting project. Therefore, using The monitoring of ground vibration by blasting sensors is of great significance to the researc...

AI Technical Summary

Problems solved by technology

The blasting project will also produce flying rocks. Small sand and rocks hitting the sensor will lead to inaccurate monitoring data. Large flying rocks hitting the sensor will directly damage the sensor and cause monitoring failure.

[0004] At present, there are few researches on the protection of blasting sensors. When the monitoring point is close to the blasting center, the shock waves and flying rocks generated by the blasting often lead to monitoring failures and instrument damage, resulting in loss of manpower and material resources. The protection device that prevents blasting sensors from being affected by blasting shock waves and flying stones is of great significance to the evaluation of blasting engineering safety and the research of blasting vibration
