Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of blasting, in particular to a memory alloy constrained blasting device. Background technique [0002] With the rapid development of blasting technology, tasks such as building blasting and dangerous goods detonation tend to be diversified and complicated. More and more blasting devices need to have the characteristics of remote control, reliable function, and high safety. [0003] The current blasting initiation end usually adopts electric detonator or nonel detonator to detonate, and nonel detonator or electric detonator is used as the initiation end, which is usually easily disturbed by static electricity, radio frequency electricity and stray current, which is easy to cause premature explosion accidents. poses a greater security risk. Contents of the invention [0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a memory alloy constrained blasting...
