Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to a fire protection ventilation device embedded in a wall. Background Art

[0002] Almost any form of combustion produces smoke gases that are somewhat toxic. The toxicity comes not only from carbon monoxide gas, but also from the various plastic components in building materials. Toxic gases produced immediately after a fire breaks out can cause smoke poisoning. For example, when PVC burns, hydrochloric acid gas is released, and when polyamide burns, ammonia gas is released. When some plastics burn, they even release hydrocyanic acid gas, which can prevent cells from absorbing oxygen and cause people to suffocate. Therefore, smoke must be discharged to the outside before it spreads in the building.

The driving motor 14 drives the transmission column 15 and the fan blades 16 to rotate synchronously, and the airflow is guided by the guide tube 12, which can further promote air circulation. The driving motor 14 can provide a strong driving force to enhance the wind force of the ventilation device, which can more quickly and effectively discharge smoke, toxic gases and hot air, improve ventilation efficiency, help personnel evacuation and fire extinguishing, and accelerate the air circulation inside the building, improve indoor air quality, and improve the working and living environment. When the dustproof net 7 needs to be removed, the installation plate three 6 is directly pulled outward with great force, so that the plug-in frame 8 moves synchronously and contacts the elastic member 5 at the same time, causing it to deform, and then the installation plate three 6 is pulled out as a whole, thereby completing the disassembly. Conversely, the installation can be completed by pushing it inward, which makes it more convenient to perform regular maintenance and cleaning of the ventilation device, which is conducive to keeping the ventilation device in good working condition.
