Description

Technical Field

[0001] The invention relates to the technical field of escape devices, and in particular to an emergency safety escape device for a high-rise building. Background Art

[0002] With the acceleration of urbanization, the number of high-rise buildings continues to increase. While these buildings provide living and office space, they also bring new safety challenges. Especially in emergency situations such as fires and earthquakes, escape from high-rise buildings is difficult and the evacuation efficiency is low. Traditional escape methods mainly rely on stairs and elevators, but in an emergency, stairs may become unavailable due to the spread of fire, and elevators may stop operating due to power outages. In addition, the escape speed of stairs is limited by the density of people, and in emergency situations such as fires, smoke and high temperatures pose a great threat to people's ability to escape.

[0003] At present, the traditional emergency safety escape device of high-rise buildings can only transport one group of people at a time during rescue, and it requires multiple round trips, which wastes a lot of time. In addition, in the event of an emergency fire, the energy supply system of the building is easily damaged, resulting in power outages and other situations. The escape device relies on energy to operate. Once the energy supply is interrupted, the escape device will not be able to work normally, thus affecting the life safety of the escapees. In addition, when escaping from a high-rise building, due to the high height, the escapee's landing speed is too fast, which will cause impact and easily cause harm to the escapee, making the equipment less practical. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcoming of poor practicability of the equipment existing in the prior art, and to propose a high-rise building emergency safety escape device.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an emergency safety escape device for a high-rise building, including an escape well and an escape component, wherein the escape component includes a solid plate, and the four sides of the solid plate are respectively provided with a front side plate, a rear side plate, a left side plate and a right side plate, and a porous plate is provided at the bottom of the solid plate, and the porous plate and the solid plate are fixedly connected with a plurality of springs, and rollers are rotatably connected between the solid plate and the porous plate through a roller shaft, and there are two groups of rollers, and the two groups of rollers are symmetrically distributed on both sides of the solid plate and the porous plate, the roller shaft is a V-shaped structure, and the solid plate and the porous plate are respectively rotatably connected to the two ends of the roller shaft, and the inner wall of the escape well is provided with two groups of roller grooves, and the two groups of roller grooves correspond to the two groups of rollers respectively, and the rollers are slidably connected to the roller grooves, and a sinking pool is provided at the inner bottom of the escape well, and the depth of the roller groove close to the sinking pool gradually becomes shallower.

[0006] Preferably, a ladder is fixedly mounted on the inner wall of the escape well.

[0007] Preferably, a nozzle is provided on the inner wall of the escape well.

[0008] Preferably, the left side panel corresponds to the right side panel and is rotatably connected to the solid panel, the front side panel corresponds to the rear side panel, and the rear side panel corresponds to the ladder, and the front side panel and the rear side panel are rotatably connected to the solid panel via hinges respectively.

[0009] Preferably, the tops of the left and right plates are rotatably connected with handles via rotating shafts, friction blocks are fixedly installed on the sides of the two handles away from each other, and the side of the friction block close to the inner wall of the escape well is set as an arc surface.

[0010] Preferably, a side of the rear side plate close to the ladder is rotatably connected with an arc-shaped leaf through a damping shaft, the arc-shaped leaf is made of a metal material, and one end of the arc-shaped leaf away from the damping shaft is in contact with the ladder.

[0011] Preferably, a rocker arm is provided on the side wall of the rear side plate, the central part of the rocker arm is fixedly connected to the rear side plate, the two ends of the rocker arm correspond to the arc-shaped leaves and the ladder respectively, and the end of the rocker arm close to the ladder is rotatably connected with a tiger's mouth-shaped half ring.

[0012] Preferably, a plurality of groups of partitions are rotatably connected in the escape well, and the plurality of groups of partitions are linearly distributed from top to bottom.

[0013] Preferably, a plurality of adjustment components are arranged in the escape well, and the plurality of adjustment components respectively correspond to a plurality of partitions. The adjustment components include a first rotating shaft, which is rotatably and slidably connected in the escape well, and a metal belt is fixedly connected to the corresponding partition. Two groups of damping devices are fixedly installed in the escape well, and a variable stiffness spring is arranged on the outer wall of the damping device. The first rotating shaft is located above the two groups of damping devices and is rotatably connected to the damping device. Gears are fixedly installed on both ends of the first rotating shaft, and a toothed groove is arranged on the outer wall of the front side plate, and the toothed groove corresponds to the gear.

[0014] Preferably, a second rotating shaft and a third rotating shaft are rotatably connected in the escape well, and the metal belt is sleeved on the outer walls of the second rotating shaft and the third rotating shaft.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. When installing the escape component of the present invention, the two groups of rollers are compressed inwardly, and the roller shaft pushes the solid plate and the porous plate away from each other, so that the spring is in a stretched state, and the tension of the spring is used to make the roller fit tightly with the roller groove, and the elastic potential energy of the spring is used to ensure a tight and stable connection between the roller and the roller groove, thereby ensuring the stability of the escape component moving up and down in the escape well. The tension of the spring can buffer some unexpected impact forces and prevent the roller from accidentally detaching from the roller groove, thereby ensuring the safety of the escape process. When the solid plate approaches the ground, the depth of the roller groove gradually becomes shallower, resulting in an increase in the pressure and friction of the roller on the roller groove, thereby slowing down the overall descent speed and avoiding the safety risks that may be caused by excessive descent.

[0017] 2. The present invention arranges devices such as a porous plate and a sinking tank. After the roller leaves the roller groove, the porous plate first contacts the water surface in the sinking tank. The buoyancy of the water will generate an upward force on the porous plate. At the same time, the continued descent of the solid plate will exert a downward force on the porous plate, causing the spring to be further compressed, converting the downward impact force into elastic potential energy of the spring, thereby achieving a buffering effect. The porous setting on the surface of the porous plate allows water to flow in from the holes in a dispersed manner, further dispersing the impact force, and dispersing the impact force that was originally easily concentrated at a certain point to multiple positions, effectively reducing the impact force on the solid plate, ensuring the safety of escapees when landing, and reducing the risk of injury.

[0018] 3. The present invention provides devices such as friction blocks and handles. By pulling the handle upward, the pressure of the friction block on the inner wall of the escape well can be adjusted, thereby changing the friction force and the descent speed, so that the escapee can control the descent speed according to his own ability and escape environment, avoiding the danger caused by excessive speed. By providing a controllable descent speed and a buffering effect, it helps to reduce the psychological pressure of the escapee, thereby enhancing the practicality of the equipment.

[0019] 4. The present invention is provided with devices such as a damping shaft and arc leaves. When the rear side plate is descending, the arc leaves collide with the ladder to rotate the damping shaft. The deformation of the metal spiral arc leaves when impacted can absorb part of the impact force. This deformation can absorb part of the impact force, thereby slowing down the falling speed of the box and making the falling process smoother. The rotation of the damping shaft helps to further disperse and absorb the impact force and maintain stability during the falling process. The arc leaves will hit the rocker arm during the rotation, causing the arc leaves to rotate in the opposite direction. At the same time, the upper half ring of the rocker arm will also rotate and collide with the upper end of the ladder. The rocker arm and the arc leaves work together to more effectively control the falling speed of the escape assembly and further ensure the stability of the falling process.

[0020] 5. The present invention provides a partition to block falling objects that may appear during the escape process, protect the escapees from harm during the falling process, and improve the safety of escape. The partition can also block the rising airflow to prevent the occurrence of chimney effect, thereby reducing the threat of toxic smoke to the escapees. The automatic opening and closing of the partition is realized through the contact between the toothed groove and the gear, without manual operation, thereby improving the efficiency and convenience of escape. The coordinated use of the variable stiffness spring and the yangni device allows the partition to have a smooth transition during the opening and closing process, avoiding discomfort or injury to the escapees caused by sudden opening and closing. During the opening and closing of the partition, the area that the escapees are about to enter is fanned, and the water mist sprayed from the nozzle can effectively reduce the temperature. The fanning action can also blow away the existing smoke and other harmful substances, and at the same time introduce fresh air, further ensuring the life, health and safety of the escapees, thereby enhancing the practicality of the equipment.

[0021] 6. The present invention can sequentially lower multiple groups of escape components at certain intervals, allowing personnel to enter the escape passage in an orderly manner at different time points, thereby improving the evacuation efficiency of the escape well. There is no need to transport escapees back and forth like traditional escape devices, thereby greatly improving the rescue efficiency in disasters. The escape well is relatively independent, can reduce smoke interference, and create a relatively safe environment for escapees. It does not need to be operated by energy, can adapt to more complex escape situations, and avoids escape failures caused by energy problems. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figures 1 to 7 , an emergency safety escape device for a high-rise building, comprising an escape well 1, the escape well 1 being arranged on the ground 4, a ladder 2 being fixedly installed on the inner wall of the escape well 1, a nozzle 3 being arranged on the inner wall of the escape well 1, the nozzle 3 corresponding to the ladder 2, personnel can move downward through the ladder 2, and escape with the help of an external device descender. In an emergency such as a fire, the stairwell is easily difficult to pass due to smoke, while the escape well 1 is relatively independent and can reduce smoke interference. The nozzle 3 sprays water, and the water can reduce the temperature in the escape well 1, preventing the high temperature from causing harm to the escapees, and creating a relatively safe environment for the escapees.

[0032] An escape assembly is provided inside the escape well 1. The escape assembly is arranged on the side of the ladder 2 away from the sprinkler 3. The escape assembly includes a solid plate 15. The four sides of the solid plate 15 are respectively provided with a front side plate 7, a rear side plate 8, a left side plate 9 and a right side plate 10. The left side plate 9 corresponds to the right side plate 10 and is rotatably connected to the solid plate 15. The left side plate 9 and the right side plate 10 fit together, which is helpful for storing the escape assembly at a later stage. The front side plate 7 corresponds to the rear side plate 8, and the rear side plate 8 corresponds to the ladder 2. The front side plate 7 and the rear side plate 8 are rotatably connected to the solid plate 15 through hinges 30, respectively. A torsion spring is arranged inside the hinge 30. The sides of the front side plate 7 and the rear side plate 8 that are close to each other are in contact with the left side plate 9 and the right side plate 10. The setting of the hinge 30 enables the front side plate 7 and the rear side plate 8 to always move toward the direction close to the solid plate 15. The left and right panels 10 are rotated to the left and right sides, respectively (this is the prior art and will not be described in detail here), so that the two ends of the left and right panels 9, 10 are clamped by the front and rear panels 7, 8. After the escape work is completed, the left and right panels 10 are rotated to fit the left and right panels 10 with the top of the solid panel 15, and the front and rear panels 7, 8 are rotated to fit the left and right panels 10, and the left and right panels 10 are pressed tightly, so that the escape components can be compactly stored after use and stored in a smaller space. There are multiple groups of escape components. When escaping, the escape components can be used to move downward from the top of the escape well 1 for escape at intervals, so that the escapees can enter the escape passage in an orderly manner at different time points, avoiding mutual interference, and improving the overall evacuation efficiency of the escape well 1.

[0033] A porous plate 17 is provided at the bottom of the solid plate 15, and a plurality of springs 16 are fixedly connected to the porous plate 17 and the solid plate 15. A roller 19 is rotatably connected between the solid plate 15 and the porous plate 17 through a roller shaft 18. There are two groups of rollers 19, and the two groups of rollers 19 are symmetrically distributed on both sides of the solid plate 15 and the porous plate 17. The roller shaft 18 is a V-shaped structure. The solid plate 15 and the porous plate 17 are rotatably connected to the two ends of the roller shaft 18, respectively. Two groups of roller grooves 5 are provided on the inner wall of the escape well 1, and the two groups of roller grooves 5 correspond to the two groups of rollers 19, respectively, and the rollers 19 are slidably connected to the roller grooves 5. When the escape assembly is installed, the rollers 19 are rotated. When the wheel 19 enters the corresponding roller groove 5, the roller 19 is squeezed, the V-shaped opening of the roller shaft 18 becomes larger, the distance between the solid plate 15 and the porous plate 17 becomes larger, and the spring 16 is in a stretched state, so that the solid plate 15 and the porous plate 17 tend to approach each other, making the connection between the roller 19 and the roller groove 5 tighter, and the escape component runs more smoothly in the escape well 1. Even if there are some unevenness or small obstacles on the inner wall of the escape well 1, the vibration of the roller 19 will be buffered by the spring 16 to avoid violent shaking of the escape component, providing a relatively comfortable and safe escape environment for the escapee.

[0034] The tops of the left side plate 9 and the right side plate 10 are respectively connected to the handle 20 through the rotating shaft 31, and the handle 20 is provided with an unlocking column. The rotating shaft 31 can be unlocked by rotating the unlocking column. The handle 20 can be rotated only after the rotating shaft 31 is unlocked, so that the handle 20 rotates around the rotating shaft 31. The rotating shaft 31 and the unlocking column on the handle 20 are similar to the structure of a mechanical lock and a key (this is the prior art and will not be repeated here). The two handles 20 are respectively fixedly installed with friction blocks 21 on the sides away from each other, and the side of the friction block 21 close to the inner wall of the escape well 1 is set as an arc surface. The escape component is placed in the escape well 1. The two friction blocks 21 are supported on the upper end of the escape well 1 to prevent the escape component from accidentally slipping when it is not ready, giving the escapee enough time to prepare, unlock the rotating shaft 31, hold the two handles 20 and rotate relative to each other. Thereby, the friction block 21 installed on the handle 20 moves in the direction away from the escape well 1, releasing the restriction of the friction block 21 on the escape component, and the roller 19 drives the escape component to move downward along the roller groove 5, thereby realizing manual control of the descent process of the escape component. The escapee can start the descent process according to his own rhythm and the actual situation in the escape well 1, thereby increasing the safety of the descent process. During the escape process, the two handles 20 are turned upward, and the pressure of the friction block 21 on the inner wall of the escape well 1 is controlled by controlling the force of pulling the handle 20. According to the principle of friction, the magnitude of friction is proportional to pressure. When the pressure of the friction block 21 on the inner wall of the escape well 1 is increased, the friction increases, and the descent speed of the escape component will slow down. Conversely, when the pressure is reduced, the friction decreases and the descent speed increases. In this way, the escapee can flexibly adjust the descent speed.

[0035] The side of the rear side plate 8 close to the ladder 2 is rotatably connected with an arc leaf 13 through a damping shaft 12. The arc leaf 13 is made of metal material, and one end of the arc leaf 13 away from the damping shaft 12 contacts the ladder 2. A rocker arm 14 is provided on the side wall of the rear side plate 8. The central part of the rocker arm 14 is fixedly connected to the rear side plate 8, and the two ends of the rocker arm 14 correspond to the arc leaf 13 and the ladder 2 respectively. The end of the rocker arm 14 close to the ladder 2 is rotatably connected with a tiger's mouth-shaped semi-ring. During the descent of the solid plate 15, the end of the arc leaf 13 contacts the ladder 2, driving the damping shaft 12 installed on the rear side plate 8 to rotate. When the arc leaf 13 is impacted, it will produce a certain deformation. The arc leaf 13 will hit the rocker arm 14 during the rotation process, so that The thumb-and-mouth-shaped semi-ring of the rocker arm 14 rotates and collides with the upper end of the ladder 2. The arc-shaped leaves 13, the damping shaft 12, the rocker arm 14 and the thumb-and-mouth-shaped semi-ring work together to effectively absorb the impact force. When the impact force is absorbed, the vibration and impact transmitted to the entire escape assembly will be reduced, making the device more stable during the descent process, providing a relatively comfortable and safe environment for the escapees, and avoiding injuries to the escapees or damage to the device due to severe shaking and impact. The presence of the damping shaft 12 also helps to control the descent speed. When the arc-shaped leaves 13 rotate, the damping shaft 12 will generate a certain resistance, which can slow down the rotation speed of the arc-shaped leaves 13, thereby playing a certain regulating role in the descent speed of the entire device.

[0036] There are multiple groups of partitions 29 rotatably connected in the escape well 1, and the multiple groups of partitions 29 are linearly distributed from top to bottom. The partitions 29 correspond to the ladder 2. There are multiple groups of adjustment components in the escape well 1, and the multiple groups of adjustment components correspond to the multiple groups of partitions 29 respectively. The adjustment components include two groups of damping devices 28 fixedly installed on the inner wall of the escape well 1. The outer wall of the damping device 28 is provided with a variable stiffness spring 27. The variable stiffness spring 27 can adjust the stiffness of the structure according to the changes in the external environment, thereby reducing the vibration effect on the structure (this is the prior art). A first rotating shaft 23 is rotatably and slidably connected in the escape well 1. The first rotating shaft 23 is located above the two groups of damping devices 28 and is connected to the damping device 28 is rotatably connected, gears 22 are fixedly installed at both ends of the first rotating shaft 23, and the two gears 22 correspond to the two groups of damping devices 28 respectively. The second rotating shaft 25 and the third rotating shaft 26 are rotatably connected in the escape well 1. The first rotating shaft 23 and the corresponding partition plate 29 are fixedly connected with a metal belt 24, and the metal belt 24 is sleeved on the outer walls of the second rotating shaft 25 and the third rotating shaft 26. The outer wall of the front side plate 7 is provided with a toothed groove 11, and the toothed groove 11 corresponds to the gear 22. During the descending process of the front side plate 7, when the gear 22 passes through the toothed groove 11, the first rotating shaft 23 is acted upon by the front side plate 7 to press the damping device 28 downward. At the same time, due to the meshing of the gear 22 and the toothed groove 11, the first rotating shaft 23 The shaft 23 will also rotate during the downward movement, thereby retracting the metal belt 24 and pulling the partition 29 to rotate downward to open. After the escape assembly passes the partition 29, under the action of the variable stiffness spring 27 and the damping device 28, the first rotating shaft 23 moves upward, and the first rotating shaft 23 rotates under the force of the metal belt 24, and the lower partition 29 rotates slowly until it contacts the lower side of the corresponding part of the ladder 2 and stops, automatically triggering the opening mechanism of the partition 29, facilitating the passage of the escapee. The partition 29 has a protective effect on the space below it, blocking possible falling debris or smoke, etc., and providing a relatively safe passage for subsequent escapees. The front side plate 7 descends to make the first The rotating shaft 23 presses down the damping device 28, and the damping device 28 can effectively buffer the impact force caused by the descent of the front side plate 7, and convert the instantaneous impact force into a more moderate force, thereby improving the reliability and stability of the entire system. The setting of the variable stiffness spring 27 enables the system to flexibly adapt to different escape situations. When the escape component moves at a faster speed and the impact force is larger, the variable stiffness spring 27 can adaptively change the stiffness to better play the role of buffering and restoring the position of the partition 29. When the escape component moves at a slower speed and the impact force is smaller, the variable stiffness spring 27 can also be adjusted accordingly to ensure the normal opening and closing of the partition 29. This flexibility can meet the needs of various complex escape scenarios.

[0037] A sinking pool 6 is provided at the inner bottom of the escape well 1 for collecting water sprayed from the nozzle 3. The depth of the roller groove 5 close to the ground 4 gradually becomes shallower, thereby increasing the pressure and friction of the roller 19 on the roller groove 5, effectively slowing down the speed of the escape component and preventing it from rushing into the sinking pool 6 too quickly. When the roller 19 disengages from the roller groove 5, the porous plate 17 first contacts the water surface in the sinking pool 6. After the porous plate 17 contacts the water surface, the buoyancy of the water compresses the spring 16, converting the impact force into the elastic potential energy of the spring 16, thereby reducing the damage to the escape component and the escapee caused by direct impact. Moreover, the porous design of the porous plate 17 allows water to flow in dispersedly from the holes, further dispersing the impact force, making the entire falling process smoother, and greatly improving the safety of escape.

[0038] In the present invention, when a high-rise building encounters a safety accident such as a fire, an escape device is arranged in the refuge floor of the high-rise building to help high-rise personnel escape from the accident scene. First, the front side panel 7 and the rear side panel 8 are opened. The front side panel 7 and the rear side panel 8 are installed on the solid plate 15 through the hinge 30 with a torsion spring inside. Then, the handle 20 is held and opened to the left and right by the left and right sides of the mutually interlocking left and right sides. The left side panel 9 and the right side panel 10 are clamped by the front side panel 7 and the rear side panel 8 to form a box body with an open top. The hinge 30 helps to fix the left side panel 9 and the right side panel 10.

[0039] The solid plate 15 and the porous plate 17 are connected by a spring 16, and the roller 19 is connected to the solid plate 15 and the porous plate 17 through a roller shaft 18. After the two groups of rollers 19 are compressed inward by a certain amount, they are placed in the escape well 1. The roller shaft 18 is pushed by the rollers 19 to push the solid plate 15 and the porous plate 17 away from each other, so that the spring 16 is in a stretched state. By utilizing the pulling force of the spring 16, the roller 19 is tightly fitted with the roller groove 5 on the inner wall of the escape well 1, making the descent process smoother.

[0040] After the solid plate 15 is placed in the escape well 1, the friction block 21 plays a limiting role and is stuck at the upper wellhead of the escape well 1. The escapee stands on the solid plate 15, holds the handle 20 from the outside with both hands, first unlocks the rotating shaft 31, and then rotates the handle 20. The connection structure between the inner side of the rotating shaft 31 and the handle 20 is similar to a mechanical lock and a key (this is the prior art and will not be repeated here). At this time, due to the arc surface structure of the friction block 21 and the action of gravity, the box body begins to slide downward. During the sliding process of the box body, the handle 20 is pulled upward. By changing the pulling The force changes the pressure of the friction block 21 on the inner wall of the escape well 1, and then changes the friction between the friction block 21 and the inner wall of the escape well 1, so as to achieve the purpose of changing the descent speed. Pulling the handle 20 upwards is more convenient for the human body to exert force. The position of the handle 20 is relatively low, and the escape well 1 is relatively narrow. At this time, the legs of the escapee will bend unconsciously and lean forward to present a curve. At this time, the center of gravity of the human body is low. Bending the legs during the descent and landing process can play a buffering role similar to a spring, thereby reducing the possible injuries to the escapee.

[0041] A metal ladder 2 is installed on the inner wall of the escape well 1. Some people with smaller bodies can use the reciprocating descender and the ladder 2 to slowly descend and escape. A nozzle 3 is arranged in the groove of the escape well 1, which can be used to cool down, reduce dust and wet the human body and clothes in case of fire, so as to reduce the damage to the escaped personnel. During the falling process of the box body, the front end of the arc leaf 13 contacts the ladder 2, driving the damping shaft 12 installed on the rear side plate 8 to rotate. When the metal spiral arc leaf 13 is impacted, a certain amount of deformation will be produced to absorb the impact force and make the falling process smoother. During the rotation process, the arc leaf 13 will collide with the rear end of the middle fixed rocker arm 14. After the collision, the arc leaf 13 rotates in the opposite direction. After the rocker arm 14 is hit, the front end of the tiger's mouth-shaped semi-circle rotates and collides with the upper end of the ladder 2. The rocker arm 14 and the arc leaf 13 cooperate with each other to further stabilize the falling speed.

[0042] Every time the box falls a certain distance, there will be a partition 29 to separate the space. The partition 29 can block the debris falling from above during the falling process and protect the escapees from harm. Since the shape of the escape well 1 is long and narrow, the internal gas is easily heated to produce a chimney effect in the event of a fire, which seriously endangers people's lives. At this time, the partition 29 can block the rising airflow to prevent the chimney effect. When the box body approaches the partition 29 during the falling process, the toothed groove 11 on the front side plate 7 contacts the gear 22 on the inner side of the escape well 1. The gear 22 is subjected to downward pressure, which presses the variable stiffness spring 27 and the damping device 28 downward. At this time, the first rotating shaft 23 pulls the metal belt 24 woven from metal fibers downward, and the metal The belt 24 passes through the second rotating shaft 25 and the third rotating shaft 26 to pull the partition 29 to rotate and open downward. The gear 22 is driven to rotate by the toothed groove 11 while moving downward, and the metal belt 24 is rolled up to make the partition 29 fully open. After the box and the escapee have completely passed through the partition 29, the variable stiffness spring 27 and the damping device 28 slowly return to their original positions, and the lower partition 29 closes slowly until it contacts the lower side of the ladder 2 and stops. During the opening and closing process of the partition 29, the area that the escapee is about to enter is fanned, and the water mist sprayed from the nozzle 3 is used to cool down and reduce dust, while fanning away possible harmful substances such as smoke, introducing fresh air, and further protecting the life, health and safety of the escapee.

[0043] When the box body approaches the ground 4, the width of the roller groove 5 gradually narrows, the pressure and friction of the roller 19 on the roller groove 5 will increase relatively, and the overall descending speed will also slow down. When the box body continues to descend until the roller 19 is separated from the roller groove 5, the porous plate 17 first contacts the water surface in the sinking pool 6. The water in the sinking pool 6 is collected by the water sprayed from the nozzle 3. After the porous plate 17 contacts the water surface, it will be subjected to an upward force, causing the spring 16 to be compressed. At this time, the solid plate 15 continues to descend and cooperates with the compressed spring 16 to apply a downward force to the porous plate 17 to achieve a buffering effect. Due to the porous setting on the surface of the porous plate 17, water will disperse and flow in from the holes, reducing the impact force on the box body when falling into the water, making the process smoother and safer.

[0044] After falling to the ground 4, the left side plate 9 and the right side plate 10 are retracted inward, and the front side plate 7 and the rear side plate 8 are automatically closed under the action of the hinge 30. Compared with the traditional escape device, the device does not need to transport the escapees back and forth, and multiple groups of escape components can be lowered in sequence at intervals, which greatly improves the rescue efficiency of people in disasters. In addition, the operation is simple, and it does not need to be operated by energy. It can adapt to more complex escape situations and ensure people's life safety.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
