Description

Technical Field

[0001] The utility model relates to the technical field of warning devices, in particular to a safety warning device for blasting. Background Art

[0002] In earthwork projects, when explosives explode in the earth-rock medium, the strong impact force will cause the earth-rock medium to compress, deform, break, loosen and throw, which is called blasting. Blasting has great destructive power, and the splashes produced by blasting can easily injure people around the explosion point.

[0003] Among them, in order to ensure the safety of blasting, a safe area is usually demarcated before blasting, and a cordon is usually set up around the safe area to warn people not to enter the dangerous area. In actual operation, the cordon is designed as a single line and needs to be used in a large area. If the cordon is accidentally disconnected, the wind will blow the cordon away from its original position, resulting in unclear demarcation of the safe area and safety hazards. For this reason, we propose a safety warning device for blasting. Utility Model Content
