Problems solved by technology

[0002] At present, during emergency rescue, when someone is trapped in a house, rescuers can only use simple demolition tools to break the door and rescue them. The efficiency of demolition is low, which directly affects the speed of rescue.
Traditional demolition tools are usually bulky and need to be manually operated. Not only is the speed of breaking the door slow, but also their use is limited and the rescue efficiency is low.
According to the test, it takes more than 10 minutes to break into the door with traditional demolition tools
In addition, the use of traditional demolition tools requires a lot of manpower and consumes a lot of physical strength. In a dangerous environment, manually breaking the door cannot guarantee the personal safety of rescuers and trapped people.
[0003] In criminal investigation work, it is often necessary to break into the house. Whether it is through a professional unlocker who carries a lock tool and uses experience to unlock the lock, or carries a door hammer to break into the door, the effect is not ideal; Entering the house, the latter breaks the door more loudly, both of which will make the suspects in the house aware, which is not conducive to the arrest work
[0004] At present, the door lock structure commonly used in China has changed from the traditional single-point lock cylinder to the multi-point combination lock cylinder and electronic door lock, which further increases the difficulty of quickly breaking the door while improving safety.

Embodiment 1

[0049] In this embodiment, the blasting area is a single-point lock cylinder door lock on an anti-theft door. The main materials include iron, stainless steel, and copper. The thickness of the stainless steel door panel is 50 mm, and the radius of the door lock is 25 mm.

[0050] The main material used to make the shaped charge blasting device is: the density is 1.1g / cm 3 The No. 2 rock emulsion explosive, a copper ball panel with a thickness of 1mm and a radius of 25mm, a PHED-1 digital electronic detonator, and PTFE inert plates.

[0051] The manufactured and assembled energy-generating blasting charge device is adsorbed on the door lock, and the operator uses the controller to remotely detonate the digital electronic detonator. The single-point lock cylinder door lock is successfully demolished at one time.

Embodiment 2

[0053] In this embodiment, the blasting area is a multi-point lock cylinder door lock (3 locations) on the anti-theft door. The main materials include iron, stainless steel and copper. The thickness of the stainless steel door panel is 50mm, and the lock radius is 25mm.

[0054] The main material used to make the shaped charge blasting device is: the density is 1.1g / cm 3 The No. 2 rock emulsion explosive, a copper ball panel with a thickness of 1mm and a radius of 25mm, a PHED-1 digital electronic detonator, and a PTFE inert plate.

[0055] The three assembled and assembled blasting devices are adsorbed on the corresponding 3-point lock core, the operator remotely detonates the digital electronic detonator through the controller, and the multi-point lock core door lock is successfully demolished at one time.

Embodiment 3

[0057] In this embodiment, the blasting area is an anti-theft door, which is locked by a door lock and a hinge. The material includes high-strength structural steel, the thickness of the door lock is 150 mm, and the hinge is a steel hinge.

[0058] The main material used to make the shaped charge blasting device is: the density is 1.1g / cm 3 The No. 2 rock emulsion explosive, a copper ball panel with a thickness of 1mm and a radius of 25mm, a PHED-1 digital electronic detonator, and a PTFE inert plate.

[0059] The manufactured and assembled multiple energy-forming blasting charge devices are adsorbed on the door lock and hinge. The operator remotely detonates the digital electronic detonator through the controller, and the door lock and hinge are successfully demolished at one time.
