[0013] With reference to the accompanying drawings, a self-falling escape pipe for stair chimney comprises a pipe body 1 having a plurality of sections connected end to end, a compressed fabric pipe 2, an upper pipe cover 3 and a lower pipe 4.

[0014] In this embodiment, the pipe body 1 is made of materials with a certain strength and toughness, such as flame-retardant glass fibers, asbestos fibers, or flame-retardant-treated organic materials. The pipe body 1 has a two-ended hollow cylinder structure, and multiple pipe bodies 1 are arranged coaxially. The height of the pipe body 1 is adjusted to the ground level. In this embodiment, the height of the pipe body 1 is 3.1-3.4 m.

[0015] On the inside of the joints between adjacent pipe bodies 1, there are steel rings 5, which are firmly connected to each other by bolts. Specifically, the steel rings 5 ​​on both sides of the pipe body 1 are in contact with the pipe body 1, and the bolts penetrate the steel ring 5 and the joint between the upper and lower adjacent pipe bodies 1 to achieve a firm connection between the upper and lower adjacent pipe bodies 1.

[0016] Furthermore, the side of the pipe body 1 facing away from the escape door 7 is provided with a ventilation window 13 to ensure air permeability in the pipe body 1. Specifically, the ventilation window 13 is provided in the center of the pipe body 1 and is a tight mesh window protection.

[0017] On one side of the steel ring 5, an anchor 6 is connected to the wall outside the pipe body 1. Due to the arrangement of the steel ring 5, it serves as a structural support point for the targeted fastening of the pipe body 1 to the wall. Specifically, the anchor 6 has the shape of a semicircle and is firmly connected to the steel ring 5 located outside the pipe body 1 via screws. At the same time, the pipe body 1 is attached to the wall by the connection between the anchor 6 and the wall.

[0018] In the specific implementation, each connected pipe body 1 is placed on the corresponding floor, and then the pipe body 1 is firmly installed on the wall through the anchor 6 to realize the installation of the pipe body 1 on the wall.

[0019] The compressed fabric tube 2 is arranged on the tube body 1, and its upper end is firmly connected to the steel ring 5. Specifically, the cross-section of the compressed fabric tube 2 is a trapezoid with a larger upper part and a smaller lower part. In this embodiment, the compressed fabric tube 2 consists of a trumpet-style elastic, breathable fabric tube with a large upper part and a small lower part, with the upper part being loose and the lower part being tight.

[0020] In addition, the lower end of the compressed fabric tube 2 extends beyond the adjacent lower end of the pipe body 1. In this embodiment, the length of each section of the compressed fabric tube 2 is greater than 2.1 m, which can allow residents to observe the transition to the next floor whether there is someone in the upper area of ​​the compressed fabric tube 2. At the same time, you can also grasp the lower end of the compressed fabric tube 2 and jump into the pipe body 1 to escape and avoid ascending and descending, thereby achieving section-by-section detection of the fallen people, dampening the relay until it safely reaches the ground.

[0021] On one side of the tubular body 1 is an escape door 7. The escape door 7 is located on the side closest to the wall and is positioned according to the balcony (or open windows, safety exits) of the corresponding floor. The escape door 7 is shaped like a semicircle and is adapted to the tubular body 1. The upper end of the escape door 7 is slidably connected to the rail 12 provided on the tubular body 1, and its lower end is slidably connected to the anchor 6. The escape door 7 is firmly connected to the barrel body 1 via a lock.

[0022] In this embodiment, the width of the escape door 7 is 0.5 to 0.6 m and the height is 1.9 m. The escape door 7 is located in the tubular body 1 and can be rotated along the axis of the tubular body 1 to realize the connection between the escape door 7 and the tubular body 1. The switching operation between the escape door 7 and the tubular body 1 is convenient for people to enter the tubular body 1 and escape through the escape door 7. When not in use, the escape door 7 is closed and fixed by a lock between the escape door 7 and the tubular body 1.

[0023] Furthermore, to ensure the structural strength of the pipe body 1, the rail 12 is firmly connected to the wall via anchors 6 to ensure the structural strength of the pipe body 1 at the escape door 7.

[0024] An upper pipe cover 3 is located on the uppermost pipe body 1. The upper pipe cover 3 is provided with a safety rod bracket 8 that extends to the outside of the upper pipe cover 3 and is connected to the wall to facilitate the installation of the safety rope. This installation ensures that personnel can inspect and replace the fabric drums, and temporarily stay in place if too many people escape.

[0025] The upper pipe cover 3 is provided with a non-driven ventilation ball 9 to ensure air convection in the pipe body 1.

[0026] The upper end of the lower tube 4 is connected to the lowest tube body 1. The lower end of the lower tube 4 is provided with a cover 10, and the cover 10 is provided with a soft slider 11 that can accommodate it.

[0027] Specifically, the locking connection between the cover 10 and the tubular body 1 is realized by a spring pin. Under the gravity of the person sliding down, the cover 10 opens automatically under the stretching of the spring pin. The soft slider 11 automatically falls, inflates, and bounces up to ensure the safety of people of different ages during landing.

[0028] In the concrete implementation of the utility model, in case of fire, each household can open the escape door 7 through the balcony or the reserved safety door (safety exit) and then jump into the compressed fabric pipe 2 in the pipe body 1.

[0029] The utility model and its embodiments have been described above. This description is not limiting. What is shown in the drawings is only one embodiment of the utility model, and the actual structure is not limited thereto. In short, if a person of ordinary skill in the art can be inspired by the invention and, without deviating from the creative purpose of the invention, design a structural method and embodiment similar to the technical solution without creativity, they all fall within the scope of protection.
