Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting facilities, and particularly relates to a multifunctional emergency escape and evacuation passage device and method thereof. Background Art

[0002] A safety evacuation passage is a dedicated passage for guiding people to evacuate to a safe area. For example, in the event of a fire, it is a dedicated passage for guiding people to evacuate to a place not threatened by the fire. There are many people in shopping malls, and when an accident occurs, people need to evacuate through the evacuation passage.

[0003] In the prior art, the publication number CN218636499U provides a fire-fighting evacuation passage structure, including an evacuation passage main body. Smoke exhaust mechanisms are fixedly connected to the top of the inner walls on both sides of the evacuation passage main body. An emergency lighting lamp fixedly connected to the inner wall of the evacuation passage main body is provided beside each of the two smoke exhaust mechanisms. An evacuation indicator light is fixedly connected to the middle of one inner wall of the evacuation passage main body. An auxiliary mechanism is provided at the bottom of one side of the evacuation passage main body. An evacuation route sign fixedly connected to the inner wall of the evacuation passage main body is provided beside the auxiliary mechanism.

[0004] However, this kind of passage structure can only guide the trapped people in a fire to move towards the exit. The trapped people need to run to the exit by themselves, which causes the trapped people to inhale a large amount of smoke and dust when running, resulting in the trapped people being prone to poisoning and asphyxiation. It will also consume a large amount of the trapped people's physical strength and increase the risk of injury to the trapped people. Summary of the Invention

[0014] Preferably, lighting indicator lights are installed on the inner wall of the evacuation passage main body. A smoke exhaust passage is provided at the top of the evacuation passage main body. A plurality of diffusion holes are provided on one side of the smoke exhaust passage. The interior of each diffusion hole is in a hollow spherical shape. A through hole is provided on one side inside each diffusion hole. The diffusion holes communicate with the smoke exhaust passage through the through holes.

[0015] Preferably, a plurality of strip-shaped openings are provided at the top of the evacuation passage main body. A dust cover is fixed to the top of the evacuation passage main body. Both sides of the dust cover are inclined surfaces, and a plurality of side holes are provided on both sides of the dust cover.

[0016] Preferably, an installation frame is installed inside the smoke exhaust passage. A plurality of exhaust fan frames are installed inside the installation frame. Exhaust fan blades are installed inside the exhaust fan frames. The input shaft of the exhaust fan blades is connected to a fan motor;

[0017] Both sides of the outer wall of the exhaust fan frame are fixedly provided with installation blocks. A plurality of installation grooves are provided on both sides of the inner wall of the exhaust fan frame.

[0024] In the present invention, the smoke inside the evacuation passage main body enters the interior of the smoke exhaust passage, and then is dispersed and exhausted through a number of diffusion holes arranged in the same row of the smoke exhaust passage, and the smoke can be quickly exhausted. Since the cross-section of the diffusion hole is in a horn shape and the large diameter of the diffusion hole faces outward, the dispersion efficiency of the smoke can be increased.

[0025] In the present invention, the mounting blocks on both sides of the exhaust fan frame are correspondingly installed in the installation grooves, the exhaust fan frame is pushed into the interior of the mounting frame, and the mounting blocks are slid into the interior of the installation grooves.

On the top of the evacuation passage main body 1, a dust cover 20 is fixed. Both sides of the dust cover 20 are inclined surfaces. A number of side holes 21 are provided on both sides of the dust cover 20. The dust cover 20 can be used to block dust from falling into the inside of the evacuation passage main body 1 through the strip-shaped openings and provide shielding protection for the top of the evacuation passage main body 1. The smoke inside the evacuation passage main body 1 will enter the inside of the dust cover 20 through a number of strip-shaped openings, and then be dispersed and discharged through both ends of the dust cover 20 and a number of side holes 21 on both sides of the dust cover 20.

[0044] As Figure 8 and Figure 9 shown in the figure, inside the smoke exhaust passage 19, a mounting rack 22 is installed. Inside the mounting rack 22, a number of exhaust fan racks 23 are installed. Inside the exhaust fan rack 23, exhaust fan blades 24 are installed. The input shaft of the exhaust fan blades 24 is connected to a fan motor;

[0045] On both sides of the outer wall of the exhaust fan frame 23, mounting blocks 26 are fixedly installed. On both sides of the inner wall of the exhaust fan frame 23, a plurality of mounting grooves 25 are provided. The mounting grooves 25 correspond to the mounting blocks 26, and the mounting blocks 26 are installed inside the mounting grooves 25. Inside the top mounting block 26, a mounting screw hole is provided, and a mounting bolt 27 is threadedly connected to the mounting screw hole. One end of the mounting bolt 27 passes through the top of the exhaust fan frame 23.

[0046] Correspond the mounting blocks 26 on both sides of the exhaust fan frame 23 to the mounting grooves 25, push the exhaust fan frame 23 into the inside of the mounting frame 22, and slide the mounting blocks 26 into the inside of the mounting grooves 25. Then, correspond the mounting screw hole of the top mounting block 26 to the mounting bolt 27. By threadedly connecting the mounting bolt 27 with the mounting screw hole of the top mounting block 26, the position of the exhaust fan frame 23 can be restricted, and the exhaust fan frame 23 can be installed inside the mounting frame 22. Then, push the mounting frame 22 into the inside of the smoke exhaust passage 19, and then install the mounting frame 22 inside the smoke exhaust passage 19 through bolts. The fan motor drives the exhaust fan blade 24 to rotate, so that the smoke inside the smoke exhaust passage 19 can be quickly discharged, and the smoke is dispersed and discharged through a plurality of diffusion holes 28.

[0047] As Figures 1-9 shown, a usage method of a multifunctional emergency escape and evacuation passage device includes the following steps:

[0048] Step S1: Push the mounting frame 22 into the inside of the smoke exhaust passage 19, and then install the mounting frame 22 inside the smoke exhaust passage 19 through bolts. The fan motor drives the exhaust fan blade 24 to rotate, quickly discharging the smoke inside the smoke exhaust passage 19, and dispersing and discharging the smoke through a plurality of diffusion holes 28. The smoke inside the evacuation passage main body 1 will enter the inside of the dust cover 20 through a plurality of strip-shaped openings, and then be dispersed and discharged through both ends of the dust cover 20 and a plurality of side holes 21 on both sides of the dust cover 20;

[0049] Step S2: When a fire occurs, the trapped person escapes from the evacuation passage. By pulling the pull ring 14 to rotate the cushion 12, the cushion 12 is rotated to the horizontal position. The trapped person sits on the cushion 12, and the bottom of the cushion 12 contacts the moving frame 3. The gravity of the trapped person is transmitted to the moving frame 3. Since the guide rod 10 is fixed to the inner wall of the sliding groove 2, support is provided for the trapped person through the guide rod 10, the clamping block 9, the moving frame 3, and the cushion 12;

[0050] Step S3: The motor 5 drives the output shaft 6 to rotate. The output shaft 6 transmits force to the gear 7. Since the gear 7 meshes with the toothed plate 8, and the toothed plate 8 is fixed to the inner wall of the sliding groove 2, when the gear 7 rotates, the moving frame 3 drives the trapped person to move, helping the trapped person escape from the fire.
