Specific embodiment
With reference to the accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection scope be not limited by the specific implementation.
As depicted in figs. 1 and 2, a kind of blasting protection device provided in an embodiment of the present invention, comprising: by muti-piece protective unit
Guard ring made of being mutually detachably connected, every piece of protective unit include: the first steel wire 1 set gradually from inside to outside,
Two steel wires 2, third steel wire 3 and asbestos protective layer 4, the mesh of the first steel wire 1, the second steel wire 2 and third steel wire 3
It is sequentially reduced, the first steel wire 1, the second steel wire 2, third steel wire 3 and asbestos protective layer 4 are adjacent between the two by multiple
Elasticity insulation stick 5 connect, it is multiple elasticity insulation sticks 5 outsides be equipped with strength compressed spring 6, the two sides of first steel wire 1,
In the two sides of the two sides of second steel wire 2, the two sides of third steel wire 3 and asbestos protective layer 4, wherein side passes through spring 10
It is fixedly connected with sleeve 8, the other side is equipped with the loop bar 9 that socket is matched with sleeve 8, and first between adjacent two pieces of protective units
Steel wire 1, the second steel wire 2, third steel wire 3 or asbestos protective layer 4 are detachably connected by sleeve 8 and loop bar 9 respectively.
Application method and working principle: the mesh of the first steel wire 1, the second steel wire 2 and third steel wire 3 is sequentially reduced
For being sequentially reduced the impact force of explosive blasting, while successively stopping different size of slungshot fragment, finally uses asbestos protective layer 4
Tiny rubble is intercepted, while preventing spark from flying out outward, is effectively reduced or avoids the slungshot fragment and spark break to surrounding
Bad effect.
