A blasting protection device

Abstract

The invention relates to the technical field of blasting protection, and discloses a blasting protective device. The blasting protective device comprises a protective ring which is formed by detachably connecting a plurality of protective units mutually, wherein each protective unit comprises a first steel wire mesh, a second steel wire mesh, a third steel wire mesh and an asbestos protective layer which are sequentially arranged from inside to outside, wherein meshes of the first steel wire mesh, the second steel wire mesh and the third steel wire mesh are sequentially reduced; every adjacenttwo of the first steel wire mesh, the second steel wire mesh, the third steel wire mesh and the asbestos protective layer are connected through a plurality of elastic heat-insulating rods; the outersides of the elastic heat-insulating rods are fixedly equipped with strong compression springs; and among the two sides of the first steel wire mesh, the two sides of the second steel wire mesh, the two sides of the third steel wire mesh and the two sides of the asbestos protective layer, sides are fixedly connected with sleeves through springs, and the other sides are equipped with sleeve rods which are matched with the sleeves. The blasting protective device can reduce or avoid damages, on the surrounding, of flying stone fragments and sparks.

Description

technical field [0001] The invention relates to the technical field of blasting protection, in particular to a blasting protection device. Background technique [0002] In recent years, with the development of the country, many old buildings or polluting devices need to be removed by blasting. Due to the strong impact and destructive force generated by explosive blasting, in order to reduce or avoid the hazards caused by explosive blasting, protective devices are installed. However, the traditional The protection force of the protective device is weak, it is easy to be broken down, and the protective effect is poor, so it will cause greater damage to the surroundings. How to reduce or avoid this destructive force needs to be improved on the existing blasting protection device. Contents of the invention [0003] The invention provides a blast protection device which can solve the above-mentioned problems in the prior art. [0004] The invention provides a blast protection ...
