[0002] With the acceleration of urbanization and the increasing scarcity of land resources, the development and utilization of underground space has become an important way to enhance urban functions and alleviate pressure on surface space. However, in the fire protection and ventilation design of underground spaces, the coordination between smoke exhaust systems and the landscape of ground-level plazas is becoming increasingly prominent. Traditional ventilation and fire smoke exhaust systems in underground buildings typically rely on structures such as stairwells, ventilation shafts, or windows. These facilities often protrude above ground, not only occupying underground space and reducing underground utilization efficiency, but also disrupting the landscape unity of ground-level plazas. Especially in densely populated public plaza areas, protruding structures may affect pedestrian activity space and visual aesthetics. In addition, in emergencies, the fixed structure of traditional smoke exhaust facilities may pose potential risks to the safety of evacuees, such as obstructing escape routes or causing tripping or collision hazards due to structural protrusions. Therefore, a liftable smoke exhaust window for underground buildings is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 In this embodiment of the present invention, a retractable smoke exhaust window for underground buildings includes:

[0027] Smoke exhaust duct 1, wherein the smoke inlet 11 of the smoke exhaust duct 1 is connected to the fire protection system 6;

[0028] Skylight 2, wherein the skylight 2 is disposed at the smoke outlet 12 of the smoke exhaust channel 1;

[0029] Lifting component 3 is installed in the smoke exhaust channel 1 and connected to the skylight 2. It is used to ensure that the top of the skylight 2 is at the same level as the ground when no fire occurs.

[0030] Specifically, the smoke exhaust duct 1 is located on the wall. In this embodiment, the smoke exhaust duct 1 is preferably rectangular, but other shapes are also possible, depending on the actual construction conditions. The smoke inlet 11 of the smoke exhaust duct 1 is connected to the main smoke exhaust duct of the underground building's fire protection system 6. This ensures that in the event of a fire in the underground building, smoke can be exhausted from the main smoke exhaust duct of the fire protection system 6 to the smoke exhaust duct 1, and then discharged through the smoke outlet 12. The inner diameter of the smoke outlet 12 matches the outer diameter of the skylight 2, and the shape of the smoke outlet 12 is the same as that of the skylight 2. This avoids the problem of excessive gaps between the skylight 2 and the smoke outlet 12, which could cause items belonging to passersby to fall into the smoke exhaust duct 1 through the gaps and be difficult to remove. By ensuring that the top of the skylight 2 is at the same level as the ground, the use of conventional smoke exhaust ventilation systems (stairwells, ventilation shafts, or windows, etc., which require elevations above ground level) can be reduced. The design minimizes the occupation of underground space by maximizing usable space, ensuring that pedestrians cannot stand above the ground when there is no fire. This design helps to enhance the overall visual and functional coordination with the ground plaza, creating a more unified and aesthetically pleasing urban landscape. This design choice does not hinder the effective use of above-ground space due to the additional height, ensuring convenience and safety. There are two sets of lifting components 3, both of which are fixed at the bottom of the smoke exhaust duct 1. The bottom of the smoke exhaust duct 1 serves to fix the lifting components 3, while the telescopic end of the lifting components 3 is connected to the bottom of the skylight 2. When a fire occurs in the underground building, the lifting components 3 can extend their telescopic ends to lift the skylight 2. At this time, the height of the skylight 2 is much higher than the ground level, making it convenient for smoke in the underground building to be discharged through the smoke outlet 12. The lifting components 3 are specifically jacks.

[0031] Please see Figure 1-3 In one embodiment, preferably, it further includes at least one set of stabilizing components 4, with two sets of stabilizing components 4, and both sets of lifting components 3 are disposed between the two sets of stabilizing components 4. The two sets of stabilizing components 4 and the two sets of lifting components 3 are arranged in a rectangular shape. The stabilizing component 4 includes a fixed part 41 connected to the inner wall of the skylight 2 and the smoke exhaust channel 1, and a movable part 42 also connected to the inner wall of the skylight 2 and the smoke exhaust channel 1. The fixed part 41 and the movable part 42 are connected by a connecting part 43. Since the skylight 2 has a large area, usually around 200 square meters, this design can effectively resist the lateral forces generated by the activities of people on it and external crosswinds. Through the ingenious design of the connecting part 43 between the fixed part 41 and the movable part 42, not only is the overall stability of the structure enhanced, but the safety and stability of the skylight 2 in complex usage environments are also guaranteed.

[0032] Please see Figure 2In one embodiment, preferably, the fixing part 41 includes a first base 411 and a second base 412. The first base 411 is connected to the inner wall of the smoke exhaust duct 1, and the second base 412 is connected to the skylight 2. The first base 411 and the second base 412 are fixedly connected to the smoke exhaust duct 1 and the skylight 2 respectively, which can provide stable support for one end of the connecting part 43 and ensure that the position of one end of the connecting part 43 does not change. Slide rails 5 are installed on both the smoke exhaust duct 1 and the skylight 2. The movable part 42 includes a first movable seat 421 and a second movable seat 422. The first movable seat 421 is connected to the inner wall of the smoke exhaust duct 1 through the slide rail 5, and the second movable seat 422 is connected to the inner wall of the smoke exhaust duct 1 through the slide rail 5. 422 is connected to the sunroof 2 via slide rails 5. The two slide rails 5 are respectively adapted to the first movable seat 421 and the second movable seat 422, and both the first movable seat 421 and the second movable seat 422 are slidably connected to the slide rails 5 to ensure that the first movable seat 421 and the second movable seat 422 can move along the length direction of the slide rails 5, thereby adapting to the lifting height of the sunroof 2. When the sunroof 2 rises, the distance between the first movable seat 421 and the first base 411 decreases, and when the sunroof 2 falls, the distance between the first movable seat 421 and the first base 411 increases. The second base 412 and the second movable seat 422 are the same as the first movable seat 421 and the first base 411.

[0033] Please see Figure 2 In one embodiment, preferably, the connecting part 43 includes two connecting rods 431 that are intersected at their centers. The centers of the connecting rods 431 are connected by a pivot. Both connecting rods 431 can rotate around the outer circumference of the pivot, and the length direction position of the two connecting rods 431 relative to the pivot does not change. This combination ensures that the connecting rods 431 will not shift laterally and can only move in a circular motion around the pivot. One end of one connecting rod 431 is connected to the first base 411 and the other end is connected to the second movable seat 422. One end of the other connecting rod 431 is connected to the second base 412 and the other end is connected to the first movable seat 421. The ends of the connecting rods 431 are connected to the first base 411, the second base 412, and the first movable seat 422. Both the movable seat 421 and the second movable seat 422 are rotatably connected. As the skylight 2 rises or falls, the tilt angle of the connecting rod 431 changes as the distance between the fixed part 41 and the movable part 42 increases and / or decreases. When the distance between the fixed part 41 and the movable part 42 decreases, the vertical angle between the two connecting rods 431 decreases. When the distance between the fixed part 41 and the movable part 42 increases, the vertical angle between the two connecting rods 431 increases. This design ensures that the first base 411, the second base 412, the first movable seat 421, and the second movable seat 422 will not be affected when the angle of the connecting rod 431 changes. This ensures that the skylight 2 can resist the lateral forces generated by the movement of people above and crosswinds, and also ensures the stable raising and lowering of the skylight 2.

[0034] Please see Figure 5 In one embodiment, preferably, a fire protection system 6 is included. The fire protection system 6 includes a controller connected to the lifting assembly 3. The controller is also connected to a warning light 7 and an alarm buzzer 8. The fire protection system 6 also includes pipes and fire extinguishing equipment distributed in the underground building. The distribution, connection method, and control principle of the fire protection system 6 in the underground building are all existing technologies and will not be described in detail here. The fire protection system 6 also includes a controller that is communicatively connected to the lifting assembly 3, the warning light 7, and the alarm buzzer 8. When the fire protection system 6 detects a fire in the underground building, it initiates the corresponding fire extinguishing procedure. After the fire extinguishing procedure is initiated, the controller promptly triggers the warning light 7 to issue an alarm, and at the same time, the controller promptly triggers the alarm buzzer 8 to issue an alarm. The warning light 7 and the alarm buzzer 8 work together to issue an audible and visual alarm, so as to promptly evacuate the skylight 2 and the surrounding people to prevent people from remaining on the skylight 2 during the lifting process. Then the controller starts the lifting assembly 3.

[0035] Please see Figure 1-2 In one embodiment, preferably, the warning light 7 and the alarm buzzer 8 are installed inside the skylight 2 and / or the smoke exhaust duct 1. This design makes them less susceptible to damage by people and can protect the warning light 7 and the alarm buzzer 8.

[0036] Please see Figure 1-2 In one embodiment, preferably, a safety net 9 is provided around the perimeter of the skylight 2. The safety net 9 has multiple smoke vents to facilitate smoke exhaust. The presence of the safety net 9 can fill the gap between the ground and the skylight 2 during the process of the skylight 2 rising, and prevent people moving around the skylight 2 from falling below the skylight 2.
