Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of protective relaying device, including
Housing 1, the top of described housing 1 is installed with flameproof protection device 2, described flameproof protection device 2
Including installation cavity 21, evacuator 22, accumulator 23, air pump 24 and inert gas storage chamber 25, institute
The left part stating installation cavity 21 is installed with evacuator 22, and described evacuator 22 is connected by pipeline
Housing 1 is outside and housing 1 is internal, and the middle part of described installation cavity 21 is installed with accumulator 23, described
The inner side of accumulator 23 is installed with air pump 24, and described air pump 24 is by pipeline and inert gas storage
Chamber 25 is attached, and is provided with shower nozzle 3, the side of described shower nozzle 3 in the middle part of the lower section of described installation cavity 21
