Description

Technical Field

[0001] The utility model relates to the field of smoke removal devices, in particular to an emergency smoke removal device for a hotel. Background Art

[0002] Emergency smoke removal device refers to equipment used to remove smoke in emergency situations such as fire. In emergency situations such as fire, the smoke exhaust fan can quickly exhaust smoke out of the building, improve the indoor air environment, create relatively favorable conditions for personnel escape and rescue work, and play the role of emergency smoke removal. It can be used in hotels, shopping malls, warehouses and other scenarios.

[0003] In the prior art, in order to protect the fan blades from collision with external objects, smoke exhaust fans on the market usually have protective nets installed on them for protection. In order to keep the smoke exhaust fans operating normally, the smoke exhaust fans need to be cleaned and maintained regularly. When the protective net needs to be removed from the smoke exhaust fan for cleaning and maintenance of the fan blades, since the protective net is usually connected and fixed to the smoke exhaust fan with bolts, it is usually necessary to use a wrench or other tool to unscrew the bolts before the protective net can be removed from the smoke exhaust fan. Moreover, after the bolts have been in contact with the air for a long time, they may oxidize and rust, thereby increasing the difficulty of disassembly. Therefore, a hotel emergency smoke removal device is needed. Utility Model Content

[0023] Reference Figure 1-5 The utility model embodiment is a hotel emergency smoke removal device, which includes a smoke exhaust fan 1, the outer surface of the smoke exhaust fan 1 is fixedly connected with a docking ring 2, the front surface of the docking ring 2 is movably connected with a protective net 3, the outer surface of the protective net 3 is fixedly connected with a plurality of docking blocks 4, the outer surface of the docking ring 2 is fixedly connected with a plurality of positioning blocks 5, the positioning blocks 5 are provided with docking grooves 15, the outer surfaces of the docking blocks 4 are movably connected to the docking grooves 15, the outer surface of the smoke exhaust fan 1 is fixedly connected with a connecting ring 17, and the connecting ring 17 is provided with a plurality of connecting holes 18.

[0024] The outer surface of the docking ring 2 is fixedly connected with a plurality of limit boxes 6, the inner surface of the limit box 6 is fixedly connected with two limit rods 7, the outer surfaces of the two limit rods 7 are slidably connected with the same slider 8, the slider 8 is fixedly connected with two connecting blocks 9, the side surfaces of the two connecting blocks 9 are fixedly connected with connecting rods 10, the two connecting rods 10 are slidably connected with the same concave block 11, the lower surface of the concave block 11 is fixedly connected with a fixed block 12, the docking block 4 is provided with a fixed groove 16, the outer surface of the fixed block 12 is movable with the fixed groove 16 The outer surface of the slider 8 is slidably connected to the limit box 6, the limit rod 7 passes through the slider 8, the end of the connecting rod 10 away from the connecting block 9 is fixedly connected with an anti-slip block 13, the number of anti-slip blocks 13 is multiple and distributed in a circular array, the outer surface of the connecting rod 10 is slidably sleeved with a spring 14, one end of the spring 14 is fixedly connected to the side surface of the recessed block 11, the end of the spring 14 away from the recessed block 11 is fixedly connected to the side surface of the connecting block 9, the number of springs 14 is multiple and distributed in a circular array, and the connecting rod 10 passes through the recessed block 11.

[0025] Working principle: The device as a whole can be connected to other equipment through the connection hole 18 on the connection ring 17. When the protective net 3 needs to be removed from the smoke exhaust fan 1 for maintenance, the concave block 11 is pulled outward so that the concave block 11 can be moved horizontally on the connecting rod 10. At the same time, under the action of the anti-detachment block 13, the concave block 11 can be prevented from being separated from the connecting rod 10, and the moving concave block 11 can drive the fixed block 12 to move. When the moving fixed block 12 is separated from the fixing groove 16, the fixation of the positioning block 5 is released, thereby releasing the connection and fixation between the smoke exhaust fan 1 and the protective net 3. At the same time, the concave block 11 will pull the fixing block 12 during its movement. The spring 14 on the connecting block 9 makes the spring 14 in a stretched state. When the movable fixed block 12 will not affect the movement of the slider 8, the connecting block 9, the connecting rod 10, the concave block 11, the fixed block 12, the anti-dropping block 13 and the spring 14 due to the limit box 6, the anti-dropping block 13 is pushed backward, so that the movable anti-dropping block 13 can drive the fixed block 12, the concave block 11, the connecting rod 10, and the connecting block 9 to move. At the same time, the movable connecting block 9 will drive the slider 8 to move horizontally on the limit rod 7. When the movable fixed block 12 does not correspond to the fixed groove 16, the concave block 11 and the anti-dropping block 13 are released, so that the spring 14 is no longer subjected to the tension to rebound, thereby making the rebound The spring 14 can drive the concave block 11 and the fixed block 12 to move. Because the fixed block 12 does not correspond to the fixed groove 16, the fixed block 12 after moving can only contact the limit box 6 and will not enter the fixed groove 16. Then, the protective net 3 is pulled, so that the protective net 3 and the docking block 4 can be removed from the smoke exhaust fan 1, and then the fan blades and the protective net 3 on the smoke exhaust fan 1 can be cleaned and maintained respectively. After the cleaning and maintenance of the fan blades and the protective net 3 are completed, the preliminary connection between the smoke exhaust fan 1 and the protective net 3 can be achieved by inserting the docking block 4 into the docking groove 15 on the positioning block 5, and then the concave block 11 is pulled from the outside, so that the moving concave block 11 can drive the fixed While the block 12 is moving, the spring 14 is kept in a stretched state, and then the anti-slip block 13 is pulled forward, so that the movable anti-slip block 13 can drive the slider 8, the connecting block 9, the connecting rod 10, the recessed block 11 and the fixed block 12 to move. When the movable fixed block 12 corresponds to the fixed groove 16, the recessed block 11 is released, so that the spring 14 is no longer restricted by the tension and rebounds, and then the rebounded spring 14 can drive the recessed block 11 and the fixed block 12 to move. When the movable fixed block 12 enters the fixed groove 16, the fixation of the docking block 4 and the fixed block 12 is completed, and the fixation between the smoke exhaust fan 1 and the protective net 3 is completed, and then the anti-slip block 13 can be released.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
