Description

Technical Field

[0001] The invention relates to the fields of aerospace and emergency escape technology, and in particular to a tower-type folding emergency escape device and an emergency escape method. Background Art

[0002] With the acceleration of urbanization, the number of high-rise buildings has increased significantly. These buildings are facing sudden disasters such as fire and earthquake. How to achieve fast and safe escape has become an important issue for people's life safety. The escape method currently used is mostly bag escape, and similar technology is also used before rocket launches. Its principle is introduced in "First Experience of the Escape Training Tower in Space City": the escape chute contains an elastic life trough device that can isolate and protect. The outer layer of fireproof glass fiber plays an isolation role. The middle layer of special elastic material has a sliding brake function, and the inner layer supports the slide load. As an important guarantee for the life safety of high-rise residents and astronauts, the escape chute still has room for further improvement.

[0003] The following is an elaboration on the improvement direction of bag-type escape in light of the above-mentioned status quo: 1. The existing bag-type escape method relies on the friction between people and bags to achieve slow descent, which requires escapees to pay attention to the control of movements and descent speed. Human factors have a greater impact, and it is difficult for the elderly, children and disabled people to use it. If it is used to escape from a launch tower, the training intensity of astronauts will be increased; 2. When designing the structure for slow descent using friction, the interior of the escape chute is very narrow, and only one person can pass through at a time. In addition, a slow falling speed in a narrow space can easily cause hypoxia, creating a safety hazard; 3. The escape chute is not easy to store and takes up space; 4. Although there is a shock-absorbing pad at the bottom during falling, there is still a certain impact on the body when landing, which can easily cause damage to people with weaker constitutions.

[0004] The following patents point out some improvement measures for high-rise escape problems. "An Emergency Escape Mechanism" (application number 202321546818.4) proposes a folding layer structure, which solves the problem of difficult storage of traditional bag-type escapes, but it still does not deviate from the working principle of traditional bag-type escapes, and the stability of the work is greatly affected by human factors. "A High-rise Rapid Escape Device" (application number 202021336623.3) proposes to use electromagnetic damping generated by cutting magnetic lines of force for deceleration and braking. This method reduces the impact of human operation factors, but the device is bulky and inconvenient to use.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The first object of the present invention is to provide a tower-type folding emergency escape device, which controls the descending speed of the falling platform by setting a falling channel and a deceleration recovery component, utilizing the friction between the falling platform and the falling channel, and the eddy current generated between the falling platform and the falling channel. At the same time, a deceleration recovery component is set to decelerate the falling platform, thereby improving the safety level during the escape process and avoiding secondary damage caused by the escape device.

[0007] The second object of the present invention is to provide an emergency escape method, which has simple steps and is easy to operate.

The bending plate is symmetrically bent along the center line of the copper plate, and the bending plate and the copper plate form a triangular prism.

[0016] Preferably, the folding section further comprises a support rod, a limit baffle and a support pulley;

[0017] The other end of the bending plate is hingedly connected to one end of the support rod, and the other end of the support rod is fixedly connected to the support pulley, which is arranged in a support slide groove opened on the copper plate and slides along the support slide groove, one end of the copper plate overlaps the limit baffle set on one end of the bending plate, and the support rod cooperates with the limit baffle to fold and unfold the folding section.

[0018] Preferably, the deceleration and resetting assembly comprises a base, two deceleration assemblies symmetrically arranged along the base, and each of the deceleration assemblies comprises a friction rubber, a pressure plate, a moving plate, a fixed connecting rod and a movable connecting rod;

[0019] The movable connecting rod is a T-shaped connecting rod, and the movable connecting rod includes a first end point, a second end point and a third end point;

[0020] The base is fixedly connected to the building, the base is magnetically connected to the falling channel, one end of the fixed connecting rod is fixedly connected to the base, the other end of the fixed connecting rod is connected to the third end point of the movable connecting rod by a hinge, the connecting rod pulley connected to the second end point of the movable connecting rod is arranged in a connecting rod sliding groove provided on the movable plate, the first end point of the movable connecting rod is connected to the upper end of the pressure plate by a hinge, and the friction rubber is provided on the pressure plate.

[0023] Preferably, the deceleration reset component includes a reset component, and the reset component includes a controller and at least one set of drivers;

[0024] The driver comprises a coil and a sensor, wherein the coil is arranged above the sensor, and the coil and the sensor are far away from the falling platform, the sensor is arranged at the lower end of the building, and the sensor is located directly below the falling platform, and the sensor is electrically connected to the driver.

[0026] The platform body is T-shaped, the heat-insulating friction layer is arranged on the outer side of the platform body, and the elastic friction layer is arranged outside the heat-insulating friction layer at the lower end of the platform body.

[0027] Compared with the traditional bag-type escape method, the present invention uses the eddy current effect between the copper tube (falling channel) and the magnet (falling platform) to achieve deceleration. Previously, the eddy current effect was mostly used for vehicle shock absorption and deceleration. KWAG et al. (Kwag, D., Hwang, J., and Bae, JS Experimental Study for Dynamic Characteristics of Eddy Current Shock Absorber [J]. Journal of The Korean Society for Aeronautical & Space Sciences, 2007 (35): 1089-1094.) first proposed and developed the concept of eddy current shock absorber using permanent magnets. In their model, the permanent magnet moves in the copper tube and the eddy current is induced in the copper tube. Based on this principle, Professor Ji Changying's team conducted relevant research on permanent magnet eddy current retarders and published relevant articles such as "Vehicle Combined Braking Capability Based on Permanent Magnet Eddy Current Retarder", but it is almost not used in high-rise escape. Compared with the traditional escape slide, this escape method reduces the operation during use, effectively avoids the uncertain influence caused by human factors, and reduces the difficulty of use;

[0028] The traditional bag escape slide relies on the friction between people and the slide to achieve speed control. This method can only allow one person to pass through at a time, and the narrow space can easily cause slight hypoxia. The present invention adopts the eddy current effect to eliminate the idle diameter between channels, and can increase the diameter to achieve multiple people escaping at one time. The bottom is provided with a deceleration recovery component, which can reset the falling platform to achieve multiple batches of escape;

[0029] The traditional bag escape slide occupies a large space and is difficult to store. The present invention adopts the outer shell structure of the bellows and the internal mechanical structure to achieve folding, storage and release for use;

[0030] The traditional bag escape slide has a shock-absorbing pad at the bottom. This device uses a deceleration recovery component to achieve a soft landing by gradually increasing the falling resistance.

[0031] The present invention also provides an emergency escape method, which uses the tower-type folding emergency escape device, and the emergency escape method comprises the following steps:

[0032] Pull the pipe assembly and rotate it through the hinge to unfold the pipe assembly from a folded state, put the falling platform into the unfolded pipe assembly, and the falling platform descends. The deceleration and recovery assembly adjusts the descending speed of the falling platform and restores the position of the falling platform at the same time.

[0033] Preferably, the method for restoring the position of the falling platform comprises the following steps:

[0034] The controller controls the operation of the sensor and the coil to eject the falling platform to restore its position.

[0035] Compared with the prior art, the present invention has at least the following advantages:

[0036] (1) The present invention arranges a copper plate and a falling platform, utilizes the friction between the falling platform and the copper plate, and utilizes the eddy current generated between the falling platform and the copper plate to control the descending speed of the falling platform, thereby ensuring the stability of the falling platform during the descent and improving the safety performance of emergency escape.

[0037] (2) The present invention reduces the impact force when the falling platform hits the ground by arranging a deceleration copper tube, a shock-absorbing spring, a movable connecting rod and a moving rod to achieve a soft landing and reduce the secondary injuries that may be caused to the user during the escape process.

[0038] (3) The present invention accelerates the falling platform by providing a driver and a controller, so that the falling platform can return to the escape entrance for secondary use and reuse, thereby improving the rescue survival rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Example

[0056] like Figure 1-9 As shown, this embodiment provides a tower-type folding emergency escape device, which is mainly used to solve the problem that when a malfunction occurs in a space launch, astronauts can use the device to escape in time to avoid accidents. Of course, in actual processes, it can also be used in high-rise buildings, and the device can be used to escape when danger occurs.

[0057] The tower-type folding emergency escape device mainly includes three parts: a falling platform 2, a falling channel 4 and a deceleration recovery component 3. The falling platform 2 cooperates with the falling channel 4 and the deceleration recovery component 3 to control the descending speed of the falling platform 2. At the same time, the falling platform 2 can also be restored for multiple escape uses, thereby increasing safety during the escape process.

[0058] The falling platform 2 includes a platform body 201, which is a T-shaped platform. The platform body 201 is made of a strong magnet. A heat-insulating friction layer 202 is arranged on the outer side of the platform body 201 for generating friction with the falling channel 4 to reduce the falling speed. At the same time, an elastic friction layer 203 is also arranged outside the heat-insulating friction layer 202 at the lower end of the platform body 201 for cooperating with the deceleration recovery component 3 to improve the safety performance of falling and landing.

[0059] In this embodiment, the falling channel 4 is installed on the building 1 through a hinge. The falling channel 4 is usually in a folded state. When an emergency occurs, the hinge can be rotated to pull the falling channel 4, and the falling channel 4 can be unfolded under the action of gravity to form an escape channel for escape.

[0060] The falling channel 4 includes an iron shaping ring 401 and a folding section. The iron shaping ring 401 is connected to the building 1 through a hinge. The iron shaping ring 401 is clamped with the falling platform 2. Each edge of the iron shaping ring 401 is connected to the folding section, and the width of the folding section is adapted to the edge width of the iron shaping ring 401.

[0061] like Figure 3 , Figure 7 , Fig. 9 As shown, the folding section includes a copper plate 402 and a bending plate 403, one end of the bending plate 403 is detachably connected to one end of the copper plate 402, the other end of the bending plate 403 is rotatably connected to the other end of the copper plate 402 and the iron shaping ring 401 through a copper plate hinge 404, and the bending plate 403 is symmetrically bent along the center line of the copper plate 402, that is, the straight line connecting the bending part of the bending plate 403 and the center line of the copper plate 402 is perpendicular to the copper plate 402, A triangular prism is formed between the bending plate 403 and the copper plate 402. A support rod 405 is connected to the bending portion of the bending plate 403 through a hinge. The connection portion of the connecting rod is close to the other end of the bending plate 403. A support pulley 408 is fixedly connected to the other end of the support rod 405. A support chute 406 is provided on the copper plate 402. The support chute 406 is adapted to the support pulley 408, and the support pulley 408 can slide along the support chute 406. A limit baffle 407 is provided at one end of the bending plate 403. The limit baffle 407 overlaps one end of the copper plate 402 to limit the movement of the copper plate 402. The limit baffle 407 cooperates with the support rod 405 to fold, store and unfold the copper plate 402 and the bending plate 403 to save space.

[0062] like Figure 5 As shown, in order to further ensure the safety of the escapees during the escape process, the bending plate is made of smoke-proof and heat-insulating material, and the copper plate 402 is set as an arc-shaped copper plate. In order to further ensure safety, in this embodiment, the central angle of the copper plate 402 is set to 15°, and the inner side of the copper plate 402 is in contact with the user. In order to increase safety performance, the inner side of the copper plate 402 is sequentially provided with a heat-insulating layer 410 and a friction rubber layer 411.

[0063] The iron shaping ring 401 is set to be cylindrical, the center of the copper plate 402 is the same as the center of the iron shaping ring 401, the copper plate 402 is fitted with the edge of the iron shaping ring 401, and the copper plates 402 are arranged in multiple columns. The copper plates 402 in multiple columns can form a copper ring, and multiple copper rings are connected end to end to form an escape passage. That is to say, after the multiple copper plates 402 are unfolded, they can form a cylindrical escape passage with the iron shaping ring 401 to help escapees escape.

[0064] In order to ensure the stability of the escape passage, in this example, the folding sections are connected end to end via hinges, and a plurality of the folding sections may also be connected in series via a connecting chain.

[0065] In the specific operation process, the number of folding sections can be adjusted according to the specific height, such as Figure 3 , Figure 7 As shown, the copper plate 402 and the bending plate 403 are in a folded state in a normal state. After a danger occurs, the iron shaping ring 401 rotates along the hinge. After the iron shaping ring 401 is pushed out of the building 1, the folded section unfolds under the influence of gravity to form an escape passage for escape.

[0066] The deceleration and recovery assembly 3 is arranged corresponding to the falling channel 4. The deceleration and recovery assembly 3 mainly includes three parts: a base 301, a deceleration assembly and a recovery assembly. The base 301 is fixedly connected to the building 1. There are two deceleration assemblies, and the two deceleration assemblies are symmetrically arranged. Specifically, the two deceleration assemblies are symmetrically arranged along the center line of the base 301, wherein each of the deceleration assemblies includes a friction rubber 305, a pressure plate 304, a movable plate 306, a fixed link 302 and a movable link 303, wherein the movable link 303 is a T-shaped link, and the movable link 303 includes a first endpoint, a second endpoint and a third endpoint. Specifically, the first link and the second link in the movable link 303 form a T-shape, wherein one end of the first link is fixedly connected to the second link to form the T-shaped movable link 303, wherein the two endpoints of the second link are respectively a first endpoint and a second endpoint, and the other end of the first link is a third endpoint.

[0067] One end of the fixed link 302 is fixedly connected to the base 301, and the other end of the fixed link 302 is connected to the third end point of the movable link 303 by a hinge. A link pulley 307 is provided at the second end point of the movable link 303, and a link groove 308 is provided on the movable plate 306. The link pulley 307 is adapted to the link groove 308, and the link pulley 307 slides along the link groove 308. The first end point of the movable link 303 is connected to the pressure plate 304 by a hinge, and a friction rubber 305 is provided on the end surface of the pressure plate 304 away from the movable link 303.

[0068] In order to further improve the safety of escapees during landing, the deceleration assembly also includes a deceleration copper tube 309 and at least one shock-absorbing spring 310, one end of the shock-absorbing spring 310 is fixedly connected to the base 301, and the other end of the shock-absorbing spring 310 is fixedly connected to the bottom end of the pressure plate 304. The deceleration copper tube 309 is arranged at the upper end of the pressure plate 304. When the falling platform 2 descends, the deceleration copper tube 309 contacts the lower end of the falling platform 2, which can not only decelerate the falling platform 2, but also ensure the stability of the falling platform 2 after landing.

[0069] like Figure 8 As shown, the recovery component includes a controller 311 and at least one driver, wherein the driver includes a sensor 313 and a coil 312 . A plurality of driver groups are disposed on the upper end of the base 301 , and an escape exit 412 is also provided on the base 301 .

[0070] The falling channel 4 also includes a folding section connecting magnet 409, which is arranged at the lower end of the falling channel 4 and fixedly connected to the bending plate 403. The upper end of the base 301 is provided with a deceleration section connecting magnet 314. After the falling channel 4 is unfolded, the folding section connecting magnet 409 and the deceleration section connecting magnet 314 attract each other, connecting the falling channel 4 with the base 301, so that the escapee can escape safely.

[0071] In order to ensure the safety performance of the falling channel 4, the falling channel 4 is also provided with a shaped copper tube, the upper end of the shaped copper tube is fixedly connected to the iron shaped ring 401, the lower end of the shaped copper tube is fixedly connected to the bending plate 403, a smoke and heat insulation layer 410 is provided on the outer side of the shaped copper tube, and an escape entrance is opened on the shaped copper tube.

[0072] In order to further deepen the understanding of this application, the following specific operation methods are given:

[0073] (1) Usage:

[0074] When danger occurs, the user first pushes the iron shaping ring 401, and the iron shaping ring 401 rotates along the hinge, and the iron shaping ring 401 is pushed out of the building 1 through the exit reserved on the building 1. The shaping copper tube is perpendicular to the ground. Under the action of gravity, the copper plate 402 rotates along the copper plate hinge 404 until it is vertically downward and is stuck by the limit baffle 407 set on the bending plate 403. At the same time, the support rod 405 slides in the support slide groove 406 by relying on the support pulley 408 under the action of gravity. The copper plate 402 is locked under the action of the limit baffle 407 and the support rod 405. A plurality of the copper plates 402 are combined to form a cylindrical escape passage. At this time, the escapee enters from the escape entrance, steps on the falling platform 2, and falls under the action of the gravity of the escapee and the falling platform 2 (if the gravity is not enough, a counterweight can be added). During the falling process, since the falling platform 2 is composed of a strong magnet, it is locked with the copper plate 402. The escape passage formed by the plate 402 generates an excellent eddy current effect, and the falling platform 2 realizes slow descent under the combined effect of friction and eddy current effect. When it is about to land, an eddy current deceleration is generated between the lower end of the falling platform 2 and the deceleration copper tube 309 to reduce the impact force generated when the falling platform 2 contacts the moving plate 306. At the same time, the shock absorbing spring 310 further reduces the impact force. At the same time, after the moving plate 306 contacts the falling platform 2, it is forced to move downward, driving the connecting rod pulley 307 in the The connecting rod slot 308 moves from the middle of the connecting rod slot 308 to both sides, driving the movable connecting rod 303 to rotate around the fixed connecting rod 302, driving the pressure plate 304 to gradually move toward the falling platform 2, and the friction rubber 305 on the pressure plate 304 contacts the elastic friction layer 203 on the falling platform 2. During the movement of the pressure plate 304, the pressure gradually increases, and the deceleration acceleration gradually increases to achieve a soft landing. After stabilization, the escapee leaves from the escape exit 412 and completes the escape.

[0075] (2) Reset:

[0076] After the escapees leave, the controller 311 is started in the safe area. The controller 311 controls the coil 312 in the driver of the lowest group to generate magnetic force, attracting the falling platform 2 to the center of the coil 312. At this time, the sensor 313 controls the closure of the coil 312. At this time, the falling platform 2 moves upward under the action of inertia, and can be ejected after acceleration by multiple drivers, returning to the iron shaping ring 401 from the channel assembly for use by the second batch of escapees.

[0077] The present invention arranges a copper plate 402 and a falling platform 2, utilizes the friction between the falling platform 2 and the copper plate 402, and the eddy current generated between the falling platform 2 and the copper plate 402, to control the descending speed of the falling platform 2, thereby ensuring the stability of the falling platform 2 when falling and improving the safety performance of emergency escape.

[0078] The present invention cooperates with the deceleration copper tube 309, the shock absorbing spring 310, the movable connecting rod and the moving rod to reduce the impact force when the falling platform 2 hits the ground, achieves a soft landing, and reduces the secondary injuries that may be caused to the user during the escape process.

[0079] The present invention accelerates the falling platform 2 by providing a driver and a controller 311, so that the falling platform 2 can return to the escape entrance for secondary use and reuse, thereby improving the rescue survival rate.

[0080] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
