The invention provides a memory
alloy constrained
detonation device, and belongs to the technical field of
detonation. The memory
alloy constrained
detonation device comprises a detonation transmission part, memory
alloy actuators, a driving spring, a
steel ball, a status switch, an electric
detonator, a detonating part, a body, a pressing screw, a large pressing screw and a bolt. At ordinary times, the two memory alloy actuators are used for locking the detonation transmission part at a position far away from the electric
detonator, meanwhile, the status switch provides short-
circuit protection for the electric
detonator and plays a part in status indication, and even if the electric detonator accidentally works, the detonation transmission part is not detonated; after the memory alloy actuators are electrified and work, the locking of the detonation transmission part is relieved, the driving spring drives the detonation transmission part to move till the detonation transmission partis aligned with the electric detonator, and the status switch switches and disconnects short-
circuit protection for the electric detonator; and after any electric detonator works, the detonation transmission part can be detonated, and then detonates the detonating part. The memory alloy constrained detonation device has the advantages of long-range control, high safety, reliable working, status indication and the like.
