Description

Technical Field

[0001] The utility model relates to a high-rise building fire escape system and belongs to the technical field of building fire protection engineering. Background Art

[0002] The problem of fire escape in high-rise buildings is a major issue that has not been well resolved in the construction field. The main reasons are: first, the fire spreads upward quickly, and it is difficult to control before rescue arrives; second, the rescue height is limited, and it is difficult to put out the fire and save people above the 15th floor; third, the escape route is blocked. The elevator cannot operate due to power outages caused by the fire on the lower floor, and the stairs are blocked by thick smoke on the lower floor, making it impossible for people on high floors to save themselves and escape.

[0003] Therefore, how to achieve safe escape when a fire occurs in a high-rise building is a major issue that needs to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1

[0028] like Figure 1 , 3As shown in Figure 4, a high-rise building fire escape system includes an escape capsule 1 arranged on each floor, a storage room 6, an out-of-wall passage 8 and a slideway 9 for storing and sliding the escape capsule 1 out of the wall. The escape capsule 1 has a door 101, a cabin 102 and a suspended sliding speed control device. The storage room 6 is connected to the balcony or corridor of the floor, and the out-of-wall passage 8 connects the storage room 6 with the outer wall 11. The slideway 9 is located beside the exit of the out-of-wall passage 8 to prevent the escape capsule sliding down from above from affecting the escape capsule 1 on the lower floor from going out of the wall. The suspended sliding speed control device includes a cable rotating shaft 3 arranged in the escape capsule 1, a sliding cable 2 wound on the cable rotating shaft 3 and fixed on the slideway 9 beside the exit of the out-of-wall passage 8, and a speed controller 4 for controlling the unwinding speed of the cable rotating shaft 3. When a fire occurs, people who enter the escape capsule 1 slide out of the wall passage 8 to the outer wall 11 with the escape capsule 1, and slide into the slideway 9 under the traction of gravity and the zip line 2. The speed controller 4 controls the cable rotating shaft 3 to continuously unwind and release the zip line 2, so that the escape capsule 1 slides down safely. In this way, when a fire occurs in a high-rise building and becomes uncontrollable, people can slide down through the escape capsule 1 to achieve safe escape.

[0029] A door 601 for entering the storage chamber 6 is provided.

[0030] like Figure 2 As shown, the storage room 6 and the wall passage 8 share a sliding bottom surface 10 that enables the escape capsule to slide out of the wall, so that the escape capsule can smoothly get out of the wall by relying on gravity.

[0031] like Figure 3 , 4 As shown, one end of the cable shaft 3 is provided with a driving gear 301, and the speed controller 4 includes a driven gear 401 meshing with the driving gear 301, a brake disc 402 coaxial with the driven gear 401, and a left friction plate 403 and a right friction plate 404 respectively pressed against both sides of the brake disc 402. The left friction plate 403 and the right friction plate 404 are respectively pressed by a left spring 405 on the left side and a right spring 406 on the right side in a pre-compressed state, so that the speed of the cable shaft 3 releasing the zip line 2 is controlled to be 0.5-3 meters per second, such as 0.5 meters per second, such as 1 meter per second, 1.5 meters per second, 2 meters per second, 2.5 meters per second, and 3 meters per second. That is, the falling speed of the escape capsule 1 is automatically controlled within the range of 0.5-3 meters per second, which can ensure that the falling to the ground will not cause casualties to the occupants.

[0032] like Figure 5 As shown, in addition, a manual fine-tuning control handle 407 can also be provided on the speed controller 4.

[0033] A hanging pin 7 is provided on the rear wall of the storage room 6 and can be extended inward and outward of the wall for hanging the back plate of the escape capsule 1. A presser 5 is provided on the back plate in the escape capsule 1. The presser 5 has an integrally formed lever arm 501 and a pressing arm 502, and also has a support shaft 503 installed on the back plate passing through the lever arm 501 and the pressing arm 502. The pressing arm 502 presses the outer end of the hanging pin 7. When escaping, the hanging pin 7 can be pressed out of the back plate by pulling the lever arm 501, so that the escape capsule 1 slides out of the cabin.

[0034] like Figure 3 As shown, the outer layer of the wall of the escape capsule 1 is a fireproof layer 103, and the inner layer is a heat insulation layer 104, which ensures that the temperature inside the capsule will not rise significantly in a short time when sliding through fireworks.

[0035] An elastic buffer layer 105 is provided at the bottom of the escape capsule 1 to further ensure that the escapees are not harmed by the impact force when landing.

[0036] like Figure 6 As shown, the escape capsule 1 has a closable ventilation window 106 on its bulkhead; the ventilation window can be opened for ventilation and oxygen supply in a non-smoking and fire-free area.

[0037] The front wall of the escape capsule 1 is also provided with a fire-resistant transparent observation window 107 .

[0038] like Figure 1 , 6 As shown, the middle of the outer wall slideway 9 has a vertical downward sliding rope groove 13, and the sliding rope 2 for the escape capsule 1 to slide down is located in the sliding rope groove 13 during the process of the escape capsule 1 sliding down; a fixing bolt is provided in the sliding rope groove 13, and the upper end of the sliding rope 2 for the escape capsule 1 to slide down is fixed on the fixing bolt. In this way, it can be prevented that the escape capsule 1 sliding downward from above presses and rubs the sliding rope 2 of the escape capsule 1 below.

[0039] A guide cable groove 14 for hiding the upper section of the zip line 2 is provided on the side wall of the wall passage 8 and the fixing bolt (not shown) from the exit of the wall passage 8 to the zip line groove 13. In this way, when the escape capsule 1 is stored, a section of the zip line 2 from the top of the escape capsule to the zip line groove 13 is hidden in the guide cable groove 14, and the zip line groove 13 on the outer wall is covered by the outer wall decoration layer 12 to maintain the beauty of the outer wall.

[0040] Since the zipline 2 does not provide an upward pulling force to the escape capsule 1 when the escape capsule 1 is out of the wall, in order to prevent the escape capsule 1 from being suddenly affected by the pulling force of the zipline 2 after it is out of the wall, an elastic rope is used for a section of the zipline 2 from the top of the escape capsule to the zipline groove 13 when it is stored.

[0041] The entire zipline is made of fire-resistant ropes. Embodiment 2

[0042] like Figure 2 , 6As shown in FIG. 7 , a concealing plate 801 is provided at the exit of the wall surface of the wall passage 8. The upper end surface of the concealing plate 801 is installed on both sides of the upper part of the wall passage 8 through a hinge shaft 802, so that the concealing plate 801 can rotate around the hinge shaft 802 to close and open the wall passage 8. The concealing plate 801 is closed when the escape capsule 1 is in the storage state. When the escape capsule 1 slides out of the wall, the lower part of the concealing plate 801 can be pushed open, so that the escape capsule 1 slides out of the wall passage 8. The setting of the concealing plate 801 can maintain the integrity of the exterior wall from the appearance.

[0043] The escape capsule 1 is in storage, and the outer surface of the cover plate 801 and the outer wall surface have a common outer wall decoration layer 12. Here, the outer wall decoration layer 12 is only a thin layer of paint, which does not affect the opening of the cover plate 801 in an emergency.

[0044] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.
