The present invention provides an escape passage, and a plurality of embodiments are given below to describe in detail the structure of the escape passage provided by the present invention.

Example 1

As shown in Figure 1, the escape passage provided by the present invention includes: a vertical passage 100, the vertical passage 100 includes a plurality of platforms 110 arranged at intervals in the vertical direction, along the vertical direction, the platforms 110 are provided with A communication channel 111, the communication channel 111 can connect the upper and lower spaces of the platform 110, and any two adjacent communication channels 111 do not overlap vertically. Seat 120 and a driving mechanism, the driving mechanism is used to drive the lowering seat 120 to move up and down along the length of the communication channel 111 . The concrete principle is as follows: when a fire occurs, the survivors can arrive on the platform 110, then take the landing seat 120 to arrive at the platform 110 of the next floor from the floor, and the survivors move horizontally to the landing seat 120 of this floor, so that Escape from the building floor by floor, because any two adjacent communication passages 111 do not overlap vertically, so the floor descenders between two adjacent platforms 110 do not affect each other, and the escape is more orderly and faster, because the floor The existence of the lower seat 120 can save energy, and make one or more people including people with reduced mobility take the descending floor to escape in time.

The escape channel can be set in a hospital to help patients with limited mobility or the elderly escape from the fire.

The vertical channel 100 can be arranged on the outer side of the building, and each platform 110 can be flush with the bottom surface of the floor of the building, and the layer closest to the ground of the vertical channel 100 is connected with the outside world. Quickly arrive at the platform 110 corresponding to the floor, so as to descend and escape floor by floor. The escape route forms an orderly passage through the descending system, and the personnel on each floor descend layer by layer through the descending device, continuously and rapidly. For the most part, evacuate the most people per unit of time.

Because any two adjacent communication passages 111 do not overlap vertically, the communication passages 111 can be set to overlap alternately, that is, the communication passages 111 on the platforms 110 of odd-numbered layers overlap vertically, while the platforms 110 of even-numbered floors The communicating channels 111 of the vertically overlap.

Further, a guide rod 130 is provided along the length direction of the communication channel 111, and the two ends of the guide rod 130 can be respectively fixed to the upper surface and the lower surface of the two platforms 110 of the adjacent odd-numbered or even-numbered layers, and the The guide rod 130 runs through the lowering seat 120, and the lowering seat 120 can be moved along the guiding rod 130, so as to reduce the shaking of the lowering seat 120 during the lifting process. Simultaneously, because of the existence of the guide bar 130, the survivors on the platform 110 can also avoid the guide bar 130 accordingly, so as to prevent the descending seat 120 from descending and hurting the escapers.

According to the group number of vertical passages 111 in the vertical direction of the vertical passage 100, the longer and complete guide rod 130 that runs through the vertical passage 100 can be selected for use. For example, as described above, there is only one escape passage on each platform 110, and The communication passages 111 on the odd-numbered platforms 110 overlap vertically, while the communication passages 111 on the even-numbered platforms 110 overlap vertically. Then, only two guide rods 130 can be provided. In this way, through the layer-by-layer fixing of multiple platforms 110, the fixing strength of the guide rods 130 is also improved, and shaking is not easy to occur.

Further, the platform 110 is provided with a buffer mechanism 140, the buffer mechanism 140 can be a buffer rubber pad arranged at the connection between the platform 110 and the guide rod 130, or a buffer spring, or other structures with elastic properties. The buffer mechanism 140 is in the same vertical direction as the corresponding floor drop seat 120. When the floor drop seat 120 falls, it first touches the buffer mechanism 140, and the speed of the floor drop seat 120 can be gradually reduced to prevent the floor drop from falling. The lower seat 120 collides with the platform 110 .

Specifically, the landing device may include a linkage rope, a counterweight and a brake mechanism, and may also include a pulley block. One end of the linkage rope is connected to the landing seat 120, and then bypasses the pulley block, and the other end is connected to the matching rope. Heavy parts are connected; the brake mechanism is used to control the descending speed of the floor lowering seat 120 . The brake mechanism can be located on the floor descending seat 120. After the escaper takes the upper floor descending seat 120, the floor descending seat 120 can be descended by manipulating the brake mechanism, and the speed of descent can be regulated by elastically tightening the brake mechanism. After the escaper's descent is completed, after leaving the landing seat 120, the counterweight can pull the landing seat 120 back to its original position, ready to complete the next landing.

Optionally, the weight of the counterweight is greater than the gravity of the landing seat 120, the rise of the landing device can be effected by the pulling force of the counterweight, and the winding motor can also be used to drive the landing seat 120. It should be noted that the landing seat 120 can be provided with a gravity sensing device, after the floor descending seat 120 has gone down to the next floor, when the gravity sensing device senses that there is no other people's weight on the slow descending seat, the driving mechanism will pull up the floor descending seat 120, but When the gravity sensing device senses the weight of other people on the lower seat 120, it will not rise. On the one hand, it can ensure the orderly evacuation of people on the lower seat 120; Block 120 enters the building.

Further, the top of the vertical channel 100 is provided with an air vent communicating with the outside world, and each layer of the downhill platform 110 is provided with an air guide. The air enters from the escape area on the first floor and is discharged from the vents on the roof to form a chimney-like channel. According to needs, each floor is equipped with an air guide opening connected to the ground floor, and each floor is provided with switchable side vents to facilitate air entry.

A window may be provided on the side wall of the vertical channel 100, and the window communicates with the outside world. The purposes of the windows are as follows: one is to provide light from the outside entering the vertical passage 100; the other is to block the entry of smoke caused by fire and wind; the third is to facilitate external observation and provide assistance.

Example 2

As shown in Figures 2-4, the escape passage may include a transverse passage 300, the transverse passage 300 communicates with the vertical passage 100, the number of the transverse passage 300 is the same as the number of the platforms 110, and one One-to-one correspondence, escapers can first pass through the horizontal passage 300 and then enter the platform 110 corresponding to the vertical passage 100. The escape passage of this structure can be set in a complex building, such as an office building, a school, etc.

The number of transverse passages 300 on the same floor can be multiple, and the plurality of transverse passages 300 are arranged side by side in the horizontal direction at intervals, and the plurality of transverse passages 300 can pass through the corresponding inclined passages 350 to the platform of the same lower vertical passage 100 respectively. .

As a bridge connecting the interior of the building with the longitudinal passage, the horizontal passage 300 can play a role in fire prevention and smoke prevention, avoiding the spread of open flames and the diffusion of toxic gases.

The transverse channel 300 includes a water curtain area 310, and a water mist spraying device 311 is arranged on the upper part of the water curtain area 310, and the water mist spraying device 311 sprays water mist downward to form a water curtain. Along the direction of escape, there may be multiple nozzles of the water mist injection device 311, so that a water curtain can be formed within a certain length of the channel. An independent water tank and switch can be set above the water curtain area 310 for spraying water mist in the fire-blocking area, and a relatively closed area is formed by spraying the ring-shaped water curtain to play the role of fire-blocking and smoke-blocking. There are three advantages of the water curtain: First, because the diameter of the ultra-fine water mist droplets is very small, the relative surface area is 1700-5800 times larger than that of ordinary water droplets. During the vaporization process, a large amount of heat is absorbed from the surface of the burning object or the fire area . Based on the latent heat of evaporation of water at 100°C as 2257kJ/kg, the heat absorption power of water mist sprayed by each nozzle is about 300KW. The existence of the water curtain can ensure the surrounding humid environment, and the fire cannot continue to spread forward, thus blocking the open fire from entering the escape channel; temperature, and even put out the fire on the survivors to prevent the survivors from being burned; third, the water mist sprayed from top to bottom can carry the smoke and dust in the air and play a certain role in purifying the air.

A water collecting hole is also arranged on the ground of each horizontal escape passage, and the sprayed water will enter into the water collecting box between adjacent two floors through the water collecting hole, and the water in the water collecting box can be used for The water mist spraying device 311 of the horizontal passage 300 on the next floor provides an additional water source, so that on the one hand, water accumulation in the escape passage can be prevented, and on the other hand, water resources can be fully utilized.

Specifically, a grille door 320 may be provided in the transverse channel 300, and the grille door 320 may include a plurality of elastic bands 321 arranged vertically, and any two adjacent elastic bands 321 are arranged in a staggered position for Smoke is prevented from passing through the grille door 320 . When the escaper passes through the grille door 320, he needs to use both hands to push aside the closed elastic band 321 to form a hole through which a single person passes. After the escaper gets into this hole, he can leave the smoke blocking area. The elastic band 321 that loses the external force will restore the original dislocation arrangement, thereby preventing the smoke from spreading forward.

Further, the transverse channel 300 may include a smoke exhaust duct, a smoke exhaust fan and an independent power supply, and the independent power supply supplies power to the exhaust fan, so it will not be affected by fire. And the smoke inlet of the smoke exhaust pipe is located at the top of the smoke blocking area, the smoke outlet of the smoke exhaust channel 330 is set outside the building, and the smoke exhaust fan is used to exhaust the smoke in the transverse channel 300 . The smoke inlet is provided on the top of the transverse passage 300, which utilizes the characteristic that the smoke has a high temperature and moves upward when a fire breaks out. When a fire breaks out, the smoke exhaust fan starts to suck out the smoke in the smoke blocking area. At the same time, the smoke exhaust fan can be arranged at the smoke outlet, away from the fire scene, so as to ensure its normal operation when a fire occurs.

A fire door 340 may be provided between the water curtain area 310 and the grille door 320 . The material of the fire door 340 is preferably metal, which can prevent the fire from spreading when the metal door is closed. A reset mechanism can be provided between the fire door 340 and the door frame. The reset mechanism can be a spring. One end of the spring is fixed on the door frame, and the other end is fixed on the fire door 340, and the opening direction of the fire door 340 is outward, that is, It is said that the escapees in the corridor can directly push the fire door 340 open, and the pushed fire door 340 will automatically close under the action of the spring, thereby ensuring that the escapers can enter the fire door 340 at the fastest speed, while ensuring The fire door 340 is closed automatically to prevent the fire from spreading.

As mentioned above, the survivors can first pass through the water curtain area 310, then open the fire door 340, pass through the grille door 320, and finally reach the platform 110 of the vertical passage 100 to complete their descent. During this process, the horizontal passage 300 effectively prevents them from It prevents the spread of fireworks and provides a relatively safe escape environment for the escapees.

Further, the escape passage includes an inclined passage 350, and the number of the inclined passage 350 is multiple; the inclined passage 350 is arranged obliquely, and one end of the inclined passage 350 is connected to the outlet of the transverse passage 300, and the other end is connected to the platform 110 In the transverse channel 300 and the platform 110 that are connected and connected with the same inclined channel 350, the height of the transverse channel 300 relative to the ground is higher than the height of the platform 110 relative to the ground. For example, the survivors are located on the fifth floor, and after passing through the horizontal passage 300, they can descend to the platform 110 on the fourth floor through the inclined passage 350, so that they can directly descend to the first floor, which shortens the escape time and reduces the inhalation of harmful gases.

The inclined channel 350 is a centrally sealed channel with openings at both ends, so as to prevent the smoke from the lower layer from entering the inclined channel 350 and ensure that the escapees will not be choked by the smoke during the escape process.

Example 3

As shown in Figure 5, the difference from Embodiment 2 is that the escape passage includes a fireproof room 400, which can be applied to hospitals, nursing homes or residences, and the fireproof room 400 communicates with the platform 110, so The number of the fireproof rooms 400 is the same as the number of the platforms 110 , and there is a one-to-one correspondence. The connection between the fireproof rooms 400 and indoors is provided with a fireproof door 340 for preventing fire from entering the fireproof rooms 400 . That is to say, the survivors can pass through the fire door 340 and enter the fireproof room 400. A water source can be provided in the fireproof room 400, and some fire-fighting facilities can be placed, such as a gap blocking agent is prepared in the house, which is used to seal and prevent smoke from entering, and is equipped with air purification. Devices, gas masks, batteries, lighting appliances, etc., when the number of escapees is large, the fireproof room 400 can be used as a safe area for escapees to stay for a short time, and escapers can descend through the vertical passage 100 more calmly.
