AI Technical Summary

Technical Problem

Existing blasting devices are susceptible to interference from static electricity, radio frequency electricity, and stray currents, which can lead to premature detonation accidents and pose safety hazards. Furthermore, detonators and explosives must be reliably isolated to prevent accidental detonation.

Method used

A bidirectional holding electromagnet drive mechanism is used to control the sliding of the detonator, enabling switching and locking between the safe state and the detonation state. Combined with a manual safety unit and detection device, reliable isolation between the detonator and the explosive is ensured.

Benefits of technology

It improves the safety of blasting operations, ensures the safety of detonators and explosives during transportation, assembly and deployment, reduces the occurrence of premature detonation accidents, and is convenient and highly reliable to operate.

Abstract

This invention discloses a detonation device, including a housing, a detonation mechanism located in a cavity inside the housing, and an electromagnetic drive mechanism. The detonation mechanism includes an electrically controlled ignition unit, a detonator, and a detonating charge. The electrically controlled ignition unit is used to detonate the detonator, and the detonator is used to detonate the detonating charge. The electrically controlled ignition unit and the detonating charge are fixed at a relative interval at the bottom of the cavity, forming a receiving space for accommodating the detonator. The electromagnetic drive mechanism is used to drive the detonator to slide back and forth into or out of the receiving space, so that the detonator, the electrically controlled ignition unit, and the detonating charge are in an aligned or misaligned state. By controlling the electromagnetic drive mechanism to drive the detonator to slide back and forth, the switching and locking between the safe state and the detonation state can be realized, which has high reliability and ensures the safety of blasting operations.
