The working principle of the observation window blast resistance construction in above-mentioned technical proposal is explained as follows below:
The present invention is matched using the fan-shaped component 32 inside anti-riot hole 3 with heat expansion movable part 33, inside explosion-proof chamber 2
When the temperature is excessively high, expander 333 made of rubber becomes larger to push upper push-rod 331 and lower push-rod joined together by upper and lower ends
332 are displaced outwardly, since the outside of upper push-rod 331 and lower push-rod 332 is respectively and fixedly provided with triangle brace 322, and 321 institute of triangle brace
Fixed fan-shaped mouth 321 is opened, and since the explosion-proof chamber 2 that fan-shaped mouth 321 is closed is opened, keeps explosion-proof chamber inner air flow further
Realize the heat dissipation of explosion-proof chamber 2；
It is combined with reset spring 334 jointly in upper push-rod 331 and lower push-rod 332, the temperature inside explosion-proof chamber 2 gradually drops
After low, expander 333 is reduced to original state, and therefore, the motive force that upper lower push-rod is subject to gradually becomes smaller, in reset spring 334
Under the action of slowly reset, so that fan-shaped mouth 321 is closed to explosionproof hole 3, can avoid with the intermittent heat dissipation that this is realized long-term naked
The problem of 3 dust stratification of explosionproof hole of dew；
In order to facilitate use, and the retractility after using to a period of time of expander 333 can be deteriorated, at this time operator
It can discern whether to need replacing by the variation of the observation panel 33c being equipped with internal expansion body 333 visible in detail, and
By explosion-proof casing 33a combination shell fastener 33b and slip lid d1, only need slide downward slip lid d1 that can open flame proof in replacement
Shell 33a and then replacement expander 333, improve the convenience that expander 333 is replaced, and improve working efficiency.
