Description

Technical Field

[0001] The present invention relates to the technical field of high-rise escape equipment, and particularly to an externally-mounted high-rise special population emergency evacuation device. Background Art

[0002] With the development of modern society, there are more and more high-rise buildings, which also bring more severe challenges to rescue work after a fire. Especially for the rescue work of special populations including the blind, hearing and speech impaired, paraplegics, physically disabled, and patients with Alzheimer's disease, the difficulty is greater, and it also makes the probability of casualties of special populations higher than that of ordinary people.

[0003] Existing escape equipment is usually designed for ordinary people, and there is less escape equipment designed for the above-mentioned special populations. It is also difficult for special populations to use ordinary escape equipment. For example, a kind of elastic high-rise fire escape passage with automatic warning function disclosed in CN207307000U is easy to cause secondary injuries to special populations with inconvenient limbs during the escape process due to the extrusion and friction between the human body and the flexible tube, and the protection of special populations is insufficient. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problems in the prior art. The provided externally-mounted high-rise special population emergency evacuation device realizes stable landing through the friction between the surface of the capsule-shaped carrier and the inner wall of the flexible tube, avoiding the direct extrusion and friction between the inner wall of the flexible tube and the human body surface of the escapee in the existing escape equipment, which is more conducive to the safe escape of the escapee and avoids the problem of secondary injuries during the escape process.

[0005] The present invention provides an externally-mounted high-rise special population emergency evacuation device, which includes a flexible tube hung on the external wall of a building. The upper port of the flexible tube is horizontally connected to the inside of the building, and the lower port of the flexible tube is naturally vertical. The externally-mounted high-rise special population emergency evacuation device further includes: a slideway, arranged inside the building and leading to the upper port of the flexible tube; a capsule-shaped carrier, which is used to carry the escapee inside and is slidably arranged in the slideway, and can load the escapee into the flexible tube through the slideway, and rely on the friction between the surface of the capsule-shaped carrier and the inner wall of the flexible tube to safely fall to the lower port of the flexible tube, thereby realizing the transfer of the escapee to the ground.

[0006] Preferably, a capsule body is arranged on the outer periphery of the capsule-shaped carrier, and the inside of the capsule body is connected to the outlet end of a pump body. By controlling the pump body to pump fluid into the capsule body, the friction between the outer wall of the capsule body and the inner wall of the flexible tube can be changed, and thus the sliding speed of the capsule-shaped carrier in the flexible tube can be adjusted.

[0007] Preferably, a speed sensor is provided on the capsule-shaped vehicle. The speed sensor is signal-connected to a controller. The speed sensor sends the data detected during the downward movement of the capsule-shaped vehicle to the controller. The controller determines the magnitude between the data and a set speed threshold, and then controls the pump body to pump fluid into or out of the capsule in real time, so as to change the downward sliding speed of the capsule-shaped vehicle in the flexible tube.

[0008] Preferably, the bottom surface of the slideway has a chute along its length direction. A motor is provided at the end of the chute away from the capsule-shaped vehicle. The output end of the motor is connected to a screw rod. A sliding seat is threadedly connected to the screw rod. The motor controls the screw rod to rotate, so that the sliding seat pushes the end face of the capsule-shaped vehicle, and further makes the capsule-shaped vehicle slide along the slideway towards the flexible tube.

[0009] Preferably, the capsule-shaped vehicle includes a lower cabin and an upper cabin that are buckled with each other, and one side of the lower cabin and the upper cabin is hinged, and the opposite side is controlled by a lock to open and close the lower cabin and the upper cabin.

[0010] Preferably, a locking tongue is provided on the opening and closing surface of the upper cabin. A vertical slot is provided on the opening and closing surface of the lower cabin. A lock hole is provided on the side wall of the slot. A lock rod is provided in the lock hole. The lock rod can limit the locking groove on the locking tongue, thereby ensuring the closed relationship between the lower cabin and the upper cabin.

[0011] Preferably, the lock hole penetrates through the opposite side walls of the lower cabin. The lock rod is slidably arranged in the lock hole. A perforation allowing the locking tongue to pass through is provided in the middle of the lock rod. The side wall of the perforation has a first inclined surface, so that the perforation has a large-diameter hole at the upper end and a small-diameter hole at the lower end. The end of the locking tongue has a second inclined surface with the same inclination direction as the first inclined surface. A handle is provided at the end of the lock rod close to the first inclined surface. One end of a spring is connected to the end of the lock rod away from the first inclined surface, and the other end of the spring is connected to the side wall of the lower cabin, and pulls the lock rod to move towards the inside of the locking groove, realizing the locking of the lock rod to the locking tongue.

[0012] Preferably, the spring is sleeved on the lock rod. One end of the spring abuts against a baffle fixedly provided on the lock rod, and the other end of the spring abuts against the side wall of the lower cabin.

[0013] Preferably, ventilation holes are provided on the upper cabin. The end of the lower cabin corresponding to the ventilation holes is the head area of the escapee. A ventilation device is provided at the end of the lower cabin away from the ventilation holes. Straps for binding the human body and a light strip for providing illumination are provided in the lower cabin.

[0014] Preferably, an emergency call machine is provided on the inner wall side of the upper cabin. The emergency call machine is connected to the security room or an emergency contact. At the same time, a food storage room is provided on the inner wall side of the upper cabin.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In an emergency, the escapee lies flat and is fixed inside the capsule-shaped vehicle, with the head facing right. With the assistance of external personnel, the capsule-shaped vehicle is pushed towards the upper port of the flexible tube. Due to the gravitational force, the capsule-shaped vehicle slides from the upper port to the lower port of the flexible tube, and successfully transfers special personnel who are inconvenient to escape to the ground. During this process, there is friction between the surface of the capsule-shaped vehicle and the inner wall of the flexible tube, enabling the capsule-shaped vehicle to transfer the escapee at a safe falling speed.

[0016] During the process of transferring the escapee by the present external high-rise special population emergency evacuation device, the special personnel who are inconvenient to escape are wrapped inside the capsule-shaped vehicle, and stable landing is achieved through the friction between the surface of the capsule-shaped vehicle and the inner wall of the flexible tube. This avoids the direct extrusion and friction between the inner wall of the flexible tube and the human body surface of the escapee by the existing escape equipment, which is more conducive to the safe escape of the escapee and avoids the problem of secondary injury during the escape process. At the same time, the present external high-rise special population emergency evacuation device can not only conveniently transfer special populations with immovable limbs, but also transfer personnel who have fainted due to inhaling excessive exhaust gas or are in urgent need of medical treatment, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0020] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present invention belongs. Words such as "including" or "comprising" and the like mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. "Inside", "outside", "above", "below", "far", "near", "front", "rear", etc. are only used to represent relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0021] The accompanying drawings in the present invention are not drawn strictly according to the actual proportions, and the specific dimensions and quantities of each structure can be determined according to actual needs. The accompanying drawings described in the present invention are only schematic diagrams of the structures.

[0022] The external high-rise special population emergency evacuation device provided by the present invention is as Figures 1 - 3 andFigures 16 - 17 It includes a flexible pipe 1 hung on the outer wall of a building 4. The upper port of the flexible pipe 1 is horizontally connected to the inside of the building 4, and the lower port of the flexible pipe 1 is naturally vertical. This externally mounted high-rise special population emergency evacuation device further includes: a slideway 2, which is arranged inside the building and leads to the upper port of the flexible pipe 1; a capsule-shaped vehicle 3, which is used to carry escapees inside and is slidably arranged in the slideway 2, and can load the escapees into the flexible pipe 1 through the slideway 2. Relying on the friction between the surface of the capsule-shaped vehicle 3 and the inner wall of the flexible pipe 1, it can safely fall to the lower port of the flexible pipe 1, thereby realizing the transfer of the escapees to the ground.

[0023] Among them, a downwardly inclined support plate 29 is arranged outside the building 4. The support plate 29 can allow the capsule-shaped vehicle 3 to smoothly transition from a horizontal state to a vertical state inside the flexible pipe 1, avoiding problems of jamming. The lower port of the flexible pipe 1 has a certain distance from the bottom surface, usually 0.3m - 0.7m. The lower port of the flexible pipe 1 can be in an open state or a closed state. When it is in a closed state, a zipper is arranged at the lower port of the flexible pipe 1. When the capsule-shaped vehicle 3 reaches the lower port of the flexible pipe 1, the rescue personnel assist in opening the zipper, so that the capsule-shaped vehicle 3 carrying the escapees can safely fall to the ground.

[0024] The escapees lie flat and are fixed inside the capsule-shaped vehicle 3 in an emergency state, with their heads facing to the right. With the assistance of external personnel, the capsule-shaped vehicle 3 is pushed towards the upper port of the flexible pipe 1. Due to the action of gravity, the capsule-shaped vehicle 3 slides from the upper port of the flexible pipe 1 to the lower port, and smoothly transfers the special personnel who are inconvenient to escape to the ground. During this period, there is friction between the surface of the capsule-shaped vehicle 3 and the inner wall of the flexible pipe 1, enabling the capsule-shaped vehicle 3 to transfer the escapees at a safe falling speed.

[0025] During the process of this externally mounted high-rise special population emergency evacuation device transferring the escapees, the special personnel who are inconvenient to escape are wrapped inside the capsule-shaped vehicle 3, and stable descent is achieved through the friction between the surface of the capsule-shaped vehicle 3 and the inner wall of the flexible pipe 1, avoiding the direct extrusion and friction between the inner wall of the flexible pipe 1 and the human body surface of the escapees by the existing escape equipment, which is more conducive to the safe escape of the escapees and avoids the problem of secondary injuries during the escape process. At the same time, this externally mounted high-rise special population emergency evacuation device can not only conveniently transfer special populations with immobile limbs, but also transfer people who have fainted due to inhaling excessive exhaust gas or are in urgent need of medical treatment, etc.

[0026] In this embodiment, as Figure 6 a bladder 5 is arranged on the outer periphery of the capsule-shaped vehicle 3. The inside of the bladder 5 is connected to the outlet end of a pump body 6. By controlling the pump body 6 to pump fluid into the bladder 5, the friction between the outer wall of the bladder 5 and the inner wall of the flexible pipe 1 can be changed, thereby adjusting the sliding speed of the capsule-shaped vehicle 3 inside the flexible pipe 1.

[0027] A wear-resistant, heat-insulating and decelerating material is fixed to the outside of the bladder 5, such as high-temperature resistant rubber and high-temperature resistant polymer material, to reduce the damage to the bladder 5 caused by high temperature and friction.

[0028] The fluid here includes but is not limited to air and water. When the fluid is air, the pump body 6 is used to inflate or exhaust air into the bladder 5. Inflation can increase the friction force between the inner wall of the flexible tube 1 and the bladder 5, reducing the descending speed. Exhausting air can reduce the friction force between the inner wall of the flexible tube 1 and the bladder 5, increasing the descending speed. When the fluid is water, the capsule-shaped vehicle 3 is provided with a water storage bag 30. The pump body 6 is used to pump the water in the water storage bag 30 into the bladder 5, or pump the water in the bladder 5 into the water storage bag 30. Pumping water into the bladder 5 can increase the friction force between the inner wall of the flexible tube 1 and the bladder 5, reducing the descending speed. Pumping the water in the bladder 5 into the water storage bag 30 can reduce the friction force between the inner wall of the flexible tube 1 and the bladder 5, increasing the descending speed.

[0029] Preferably, the number of the bladders 5 is two. The two bladders 5 are respectively arranged at the left and right ends of the capsule-shaped vehicle 3. The outer surface of the bladder 5 has a smooth hard shell, and the hard shell is fixedly arranged on the capsule-shaped vehicle 3.

[0030] In this embodiment, as Figure 7 The capsule-shaped vehicle 3 is provided with a speed sensor 7. The speed sensor 7 is signal-connected to a controller 8. The speed sensor 7 sends the data detected during the downward movement of the capsule-shaped vehicle 3 to the controller 8. The controller 8 judges the magnitude relationship between the data and the set speed threshold, and then controls the pump body 6 to pump fluid into or out of the bladder 5 in real time to change the downward sliding speed of the capsule-shaped vehicle 3 in the flexible tube 1.

[0031] The purpose is to automatically adjust the downward movement speed of the capsule-shaped vehicle 3 during the vertical downward movement of the capsule-shaped vehicle 3, and it can also adapt to escapees with different weights, ensuring that escapees with different weights can all escape safely. For example, the set safe escape speed is 1 m / s. The speed value real-time monitored by the speed sensor 7 is sent to the controller. When the controller judges that the current speed is greater than 1 m / s, the controller issues a command for the pump body 6 to pump fluid into the bladder 5, and the bladder 5 acts to pump gas or water into the bladder 5. When the controller judges that the current speed is equal to 1 m / s, the controller does not issue an action command. When the controller judges that the current speed is less than 1 m / s, the controller issues a command for the pump body 6 to pump fluid out of the bladder 5, and the bladder 5 acts to pump the gas or water in the bladder 5 out to reduce the friction.

[0032] In this embodiment, as Figures 4 - 5The bottom surface of the slide 2 has a slide groove along its length direction, and a motor 9 is arranged at the end of the slide groove away from the capsule-shaped carrier 3. The output end of the motor 9 is connected to a screw 10, and a sliding seat 11 is threadedly connected to the screw 10. The motor 9 controls the screw 10 to rotate, so that the sliding seat 11 pushes the end surface of the capsule-shaped carrier 3, and further makes the capsule-shaped carrier 3 slide along the slide 2 toward the flexible tube 1. A switch button for controlling the action of the motor 9 is provided in the capsule-shaped carrier 3.

[0033] Among them, the capsule-shaped carrier 3 is located in the slide 2 and is located directly above the slide groove. The sliding seat 11 has a sufficiently large cross-section, which can push the capsule-shaped carrier 3 to move toward the left side on the right side of the capsule-shaped carrier 3. The two ends of the screw 10 are rotatably arranged in the slide groove through the bearing seat.

[0034] When a disaster occurs and there is no assistant beside the escapee during the escape, after lying down in the capsule-shaped vehicle 3, the electrode 9 can be controlled to rotate by pressing the switch button, so that the sliding seat 11 can push the capsule-shaped vehicle 3 toward the flexible tube 1, and the escape can be made independently.

[0035] In this embodiment, Figure 6 The capsule-shaped carrier 3 includes a lower cabin 12 and an upper cabin 13 that are interlocked with each other, and one side of the lower cabin 12 and the upper cabin 13 is hinged, and the other side opposite to the lower cabin 12 and the upper cabin 13 is controlled by a lock 14 to open and close.

[0036] The lower cabin body 12 and the upper cabin body 13 are movably connected by hinges or hinge shafts. When it is necessary to use the capsule-shaped vehicle 3 to escape, the upper cabin body 13 is opened, and after lying in the lower cabin body 12, the upper cabin body 13 is closed and locked by the lock 14. The lower cabin body 12 and the upper cabin body 13 are opened during the falling process, thereby avoiding the problem of the escapee falling.

[0037] At the same time, the capsules 5 are two C-shaped capsules 5, which are respectively arranged on the outer peripheries of the lower cabin 12 and the upper cabin 13, and the two C-shaped capsules 5 are interconnected and can be combined into a circle.

[0038] In this embodiment, Figures 8 - 15 The upper cabin body 13 has a locking tongue 15 on its opening and closing surface, the lower cabin body 12 has a vertical slot 16 on its opening and closing surface, the slot 16 has a locking hole 17 on its side wall, a locking rod 18 is provided in the locking hole 17, and the locking rod 18 can limit the locking groove 22 on the locking tongue 15, thereby ensuring the closed relationship between the lower cabin body 12 and the upper cabin body 13.

[0039] The locking rod 18 can be inserted into the locking groove 22 on the locking tongue 15 to prevent the locking tongue 15 from being separated from the slot 16 , thereby ensuring the stable closure of the lower cabin 12 and the upper cabin 13 .

[0040] In this embodiment, as Figures 8 - 15 described, the keyhole 17 penetrates through the opposite side walls of the lower cabin 12. The locking rod 18 is slidably disposed within the keyhole 17. The middle part of the locking rod 18 has a perforation 19 that allows the locking tongue 15 to pass through. The side wall of the perforation 19 has a first inclined surface, such that the perforation 19 has a large-diameter hole at the upper end and a small-diameter hole at the lower end. The end of the locking tongue 15 has a second inclined surface with the same inclination direction as that of the first inclined surface. The end of the locking rod 18 near the first inclined surface has a handle 20. One end of a spring 21 is connected to the end of the locking rod 18 far from the first inclined surface, and the other end of the spring 21 is connected to the side wall of the lower cabin 12, and pulls the locking rod 18 to move towards the inside of the locking groove 22, thereby realizing the locking of the locking rod 18 to the locking tongue 15.

[0041] After the lower cabin 12 and the upper cabin 13 are closed, the locking tongue 15 penetrates into the large-diameter hole of the perforation 19 and exits from the small-diameter hole of the perforation 19. Then, the locking rod 18 is pushed or pulled to the left, so that the locking rod 18 is clamped in the locking groove 22 on the locking tongue 15. The above structure facilitates external assistants or rescuers to open or close the capsule-shaped vehicle 3, and also facilitates the escapee to open or close the capsule-shaped vehicle 3 inside the capsule-shaped vehicle 3 by himself.

[0042] Among them, the design of the first inclined surface and the second inclined surface can ensure that the locking tongue 15 smoothly passes through the perforation 19, reducing the problem of jamming. The diameter of the handle 20 is larger than the width of the keyhole 17, which can prevent the locking rod 18 from slipping off after moving to the left during locking.

[0043] In this embodiment, as Figure 9 described, the spring 21 is sleeved on the locking rod 18. One end of the spring 21 abuts against a baffle 23 fixedly provided on the locking rod 18, and the other end of the spring 21 abuts against the side wall of the lower cabin 12.

[0044] The spring 21 can enable the locking rod 18 to be stably clamped in the locking groove 22 under the action of the spring 21 in the locked state, avoiding the problem that the lock 14 is randomly opened without human operation.

[0045] In this embodiment, as Figures 13 - 14 described, the upper cabin 13 is provided with ventilation holes 24. The end of the lower cabin 12 corresponding to the ventilation holes 24 is the head area of the escapee. A ventilation device 26 is provided at the end of the lower cabin 12 far from the ventilation holes 24. The lower cabin 12 is provided with straps for binding the human body and a light strip 25 for providing illumination.

[0046] The ventilation equipment 26, such as an exhaust fan or a fresh air system, can speed up the air circulation in the capsule-shaped vehicle 3 and avoid the problem of hypoxia inside the capsule-shaped vehicle 3. There are multiple straps, which can quickly tie the human body in the lower cabin 12, preventing the escapee's body from tipping over and colliding during the falling of the capsule-shaped vehicle 3, thereby ensuring the safety during the falling process. The light strip 25 can make the escapee clear about the environment inside the capsule-shaped vehicle 3 at all times and reduce the escapee's inner fear.

[0047] In this embodiment, Figure 7 An emergency call machine 27 is arranged on the inner wall side of the upper cabin body 13 , and the emergency call machine 27 is connected to the security room or the emergency contact person. Meanwhile, a food storage room 28 is arranged on the inner wall side of the upper cabin body 13 .

[0048] The emergency call machine 27 is used for the escapee to transmit information to the outside world at any time in the capsule-shaped vehicle 3, to inform the outside world of the escapee's own life status, and can also be used to call for help and seek help. Just in case, the food storage room 28 is placed with food and water, and even medicines for dealing with emergencies.

[0049] The method of using this external high-rise special crowd emergency evacuation device is as follows: When an emergency occurs, the locking rod 18 is moved to the right, and the upper cabin body 13 is rotated upward. The escapee lies flat and is fixed in the capsule-shaped vehicle 3 with his head facing the right. The upper cabin body 13 is closed and the locking rod 18 is automatically reset to the left and locked. With the assistance of external personnel, or by pressing the switch button, the sliding seat 11 pushes the capsule-shaped vehicle 3 into the flexible tube 1. Due to the action of gravity, the capsule-shaped vehicle 3 slides from the upper end to the lower end of the flexible tube 1, and successfully transfers special personnel who are inconvenient to escape to the ground. During this period, there is friction between the surface of the capsule-shaped vehicle 3 and the inner wall of the flexible tube 1, so that the capsule-shaped vehicle 3 can transfer the escapee at a safe falling speed. After successfully escaping, the locking rod 18 is moved to the right, the upper cabin body 13 is opened, and the escapee walks out of the capsule-shaped vehicle 3, leaves the scene, and escapes successfully.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
