The outer frame 1 is bolted to the front and rear sides of the mounting groove 21 by the fixing plate 3 and fixing bolts 4. The fixing plate 3 and fixing bolts 4 are distributed in a ring position on the front and rear sides of the outer frame 1, which makes it easy to insert bolts to fix the outer frame 1 and ensures stable installation.

[0021] The fan blades 2 are arranged in a double-group structure on the inner wall of the outer frame 1, which makes it easy for the fan blades 2 to perform double-group suction and improve the effect. The front and rear edges of the outer frame 1 are provided with pull-out grooves 10, and the inner walls of the pull-out grooves 10 are provided with limiting slide grooves 11. Limiting sliders 12 are inserted and installed on the inner walls of the limiting slide grooves 11, and a fixing plate 3 is fixedly connected between the limiting sliders 12. The fixing plate 3 is slidably and telescopically connected to the pull-out grooves 10 through the limiting slide grooves 11 and the limiting sliders 12. The fixing plate 3 is also locked and fixedly connected to the pull-out grooves 10 through the locking knob 13. This makes it easy for the fixing plate 3 to be telescopically adjusted and convenient for quick disassembly and assembly.

[0022] A locking knob 13 is inserted and installed on one side of the upper end of the fixing plate 3, and a fixing bolt 4 is inserted and installed on the other side of the upper end of the fixing plate 3. Threaded mounting grooves 20 are opened on the front and rear edges of the inner wall of the outer frame 1, and threaded mounting rings 19 are inserted and installed on the inner wall of the threaded mounting grooves 20. A protective net 7 is fixedly connected to the inner wall of the threaded mounting ring 19.

This makes it easy to provide front and rear protection for the protective net 7, and also easy to quickly disassemble and replace, making it convenient to use.

[0023] A water inlet 6 is connected to the upper front side of the outer frame 1, and a sealing cover 16 is inserted and connected to the upper end of the water inlet 6. A rotating ring 15 is installed on the upper end of the sealing cover 16, and a water inlet pipe 5 is rotatably installed on the upper end of the rotating ring 15. The water inlet pipe 5 is rotatably connected and spliced ​​with the water inlet 6 through the rotating ring 15 and the sealing cover 16. The water inlet 6 has an integrated solenoid valve structure. The spray head 9 is connected to the water inlet 6 through the water guide pipe 8. The spray head 9 is distributed in a ring-shaped protruding position on the rear edge of the outer frame 1. The smoke sensor 18 is symmetrically distributed on the rear edge of the outer frame 1. The smoke sensor 18 is electrically connected to the fan blade 2 and the water inlet 6. This allows the fan blade 2 and the water inlet 6 to be quickly detected and started by the smoke sensor 18, resulting in good smoke exhaust and heat dissipation effects.

A spray head 9 is connected in the middle of the water guide pipe 8. A smoke sensor 18 is electrically connected to the rear edge of the outer frame 1.

[0025] Working principle: When using the ventilation and smoke exhaust device for building fire protection engineering, first insert the outer frame 1 of the device into the mounting groove 21, then slide the fixing plate 3 through the limiting slide groove 11 and the limiting slider 12, and lock it in place with the locking knob 13. Next, fix it with bolts using the fixing plate 3 and fixing bolts 4. Then, connect the water inlet pipe 5 and the water inlet 6 through the rotating ring 15 and the sealing cover 16. Then connect the device to the power supply. When the smoke sensor 18 detects smoke and flames, the fan blades 2 and the water inlet 6 can be activated. The solenoid valve on the top quickly extracts the smoke through the double-set fan blades 2, and then guides water through the water inlet 6 to the water pipe 8 and the spray head 9, which quickly breaks through and assists in cooling and extinguishing the fire. When the front and rear sides are impacted, they can be protected by the protective net 7. When the protective net 7 is damaged, it can be rotated and replaced by the threaded mounting ring 19 and the threaded mounting groove 20. When the whole installation needs to be disassembled and replaced, the fixing plate 3 can be slid and retracted for quick replacement. This is the usage process of the ventilation and smoke exhaust device for fire protection engineering of this building.
