Abstract

The utility model discloses a blasting protection device, and relates to the technical field of blasting construction. The device comprises a protection component and a support component. The protection component consists of a plurality of groups of protection plates, buffer parts and connecting parts, and the support component comprises a stabilizing part, a support part, a reinforcing part, a first locking part and a second locking part. The stabilizing piece can be overturned to be vertical to the protection plate under the action of external force, so that the protection plate is vertically erected on the ground. The support piece overturns under the action of external force and forms a fixed included angle with the protection plate, so that the reinforcing piece horizontally abuts against the ground after overturned. The area of guard plate after the control of multiunit guard plate looks joint, accessible increase and decrease guard plate quantity to its coverage area of control. The spliced protection plate is convenient to assemble and disassemble, and the buffer piece is arranged on the spliced protection plate, so that impact energy of flying stones to the protection plate can be consumed. The steady piece and the support piece support respectively in the guard plate both sides, ensure that the guard plate is installed subaerial stability, provide good protection effect.
