Description

Technical Field

[0001] The utility model relates to the technical field of engineering blasting, in particular to a sensor fixing device. Background Art

[0002] During mountain blasting, sensors need to be installed to monitor harmful effects such as blasting vibration, noise, and air shock waves generated by the blasting operation.

[0003] In the prior art, sensors are often fixed on the surface of the rock mass by means of a mixture of gypsum powder and glue to monitor the blasting situation. This method takes a long time to install, and it is difficult to remove the sensor after installation, which may cause irreversible damage to the sensor. Others use a tripod-type device to fix the sensor on a tripod for monitoring. However, some blasting generates large air shock waves, which may break the support rods of the tripod, making it impossible to monitor subsequent blasting situations. In addition, when blasting in some mountains, the area around the blasting point is not flat, and the tripod is difficult to connect stably, affecting the quality of monitoring.
