Abstract
The utility model provides an explosion-proof blanket. A protection layer is arranged in the sheath body formed by the connection of a base layer and surface layer, and the definite range of the middle position of the protection layer is provided with a plurality of blast-release holes interpenetrating the protection layer. The explosion-proof blanket is square or rectangular, and its four angles are respectively provided with a sand bag, which is tailored at the inside of the surface layer and whose inside is provided with sand grain. When the dangerous blasting goods take place blast on public places, the utility model can direct the blasting energy to release upwards vertically from the middle part, stop the shock wave generated by blasting goods and the transversal effect of the fragment, and consequently alleviate or avoid damaging to people and articles around.
Description
Technical field
The utility model relates to a kind of safety device, be specifically related to a kind of at the dangerous material explosive explosion time that meets accident, the device that can protect the safety of personnel's on every side life and property to be without prejudice effectively.
Background technology
Current only a few law-breaker, terrorist take to put in public places the means of dangerous material explosive in order to endanger society, attempt to make pernicious explosive incident, make the masses' lives and properties suffer great threat.In case find this dangerous material, generally all be to report to the police immediately, evacuate the masses, wait for that the police come to dispose.Before the police arrive, still there is not the interim measure of disposing early stage at present.
The utility model content
In order to overcome the deficiency that lacks interim Disposal Measures at present at the scene of finding the dangerous material explosive; the purpose of this utility model is: a kind of explosion-proof blanket is provided; this explosion-proof blanket can be at the dangerous material explosive explosion time that meets accident; personnel and article beyond near the explosion center are implemented certain protection, ensure the safety of these personnel's life and property.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of explosion-proof blanket, it comprises bottom, surface layer and overcoat, and the edge of bottom and surface layer connects into a body, and overcoat places in this body; In the zone of the middle part of overcoat certain limit, be provided with the venting of dust explosion hole of some perforation overcoat thickness; Described explosion-proof blanket is square or rectangle, respectively is provided with a sand pocket at Qi Sijiao, and this sand pocket is made in the surface layer inboard, and sand grains is housed in the sand pocket.
The beneficial effects of the utility model are: can be at the explosive explosion times that meets accident, and to personnel's the life and the security implementation certain protection of property on every side.
Because the utility model explosion-proof blanket is provided with some ventings of dust explosion hole in certain zone of intermediate range, make the middle part want weak with respect to all the other positions, at the explosion time that meets accident, can guide explosion energy to lead off vertically upward from the centre part, the shock wave that minimizing explosive explosion time is produced and the transversal effect of fragmentation, thus blast alleviated to the infringement of personnel and article on every side.

Among the figure, 1. surface layer 2. bottoms 3. overcoats 4. venting of dust explosion holes 5. sand pockets, 6. venting of dust explosion hole scopes
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Illustrated in figures 1 and 2 is an embodiment of the utility model explosion-proof blanket, this explosion-proof blanket is a square or rectangle explosion-proof blanket, this explosion-proof blanket comprises surface layer 1, bottom 2 and overcoat 3, overcoat 3 adopts special material and forms by several layers is stacked, and this explosion-proof blanket 3 places in the body that the edge by surface layer 1 and bottom 2 connects into.Be provided with the venting of dust explosion hole 4 of some perforation overcoat 3 thickness in certain zone of overcoat middle part, the arrangement of circumference dislocation can be done in these venting of dust explosion holes 4 in the venting of dust explosion hole scope 6 that overcoat 3 middle parts are set.Four jiaos at explosion-proof blanket respectively are provided with a sand pocket 5, and this sand pocket 5 is made in surface layer 1 inboard, fills sand grains in the sand pocket.Because four jiaos heavy, can make explosion-proof blanket ensure that in use four limits are sagging, Yi Bian to prevent the hiking up possibility of fragment from laterally flying out effectively thereby minimizing is exploded.
The utility model explosion-proof blanket impales dangerous material with fence earlier, and fence is connected firmly in use, explosion-proof blanket is placed on the fence gently again, makes it sagging as far as possible and hides tight.The utility model is for to use when danger is carried out pre-process, and therefore after explosion-proof blanket is built, operating personnel should be away from explosion center, waits for that professional explosive personnel show up to do further to dispose.
Claims (3)
1, a kind of explosion-proof blanket is characterized in that: it comprises bottom, surface layer and overcoat, and the edge of bottom and surface layer connects into a body, and overcoat places in this body; In the zone of the middle part of overcoat certain limit, be provided with the venting of dust explosion hole of some perforation overcoat thickness; Described explosion-proof blanket is square or rectangle, respectively is provided with a sand pocket at Qi Sijiao, and this sand pocket is made in the surface layer inboard, and sand grains is housed in the sand pocket.
