Description

Technical Field

[0001] This invention relates to the field of fire escape equipment technology, specifically to a collective escape device and escape method for building fires, and more particularly to a household fire escape descent device suitable for use by multiple people simultaneously in urban high-rise buildings. Background Technology

[0002] With social development and scientific progress, cities are densely packed with high-rise buildings, especially high-rise residential buildings, which pose a fire risk. Once a fire breaks out, residents have very limited time to escape. For residents living on higher floors, due to the high temperatures and smoke generated as the fire spreads, as well as the potential for trampling, it is generally difficult to escape successfully using elevators or stairs.

[0003] The existing Chinese patent application document with publication number CN111084938B discloses an inflatable backpack for escaping from high-rise buildings, including a built-in switch control device, an inflation device, a functional airbag (6), an instantaneous opening parachute (7), a fixing device, and a backpack skin (8). When jumping down, pressing the start switch inflates the functional airbag (6) and the parachute airbag (10), opening the parachute. At the same time, the functional airbag (6) completely envelops the user, allowing the user to land safely.

[0004] Existing home descent devices have the following drawbacks and require improvement:

[0005] 1. Designed for single individuals, it is not suitable for multiple family members to escape together at one time;

[0006] 2. For the elderly, children and people with disabilities, it is difficult to operate the escape device independently to escape. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the purpose of this invention is to provide a collective escape device for building fires.

[0008] According to the present invention, a collective escape device for building fires includes a wearable system, a parachute system, and a damping safety rope system; the wearable system includes multiple safety harnesses, which are connected by connecting ropes, one or more safety harnesses are connected to the parachute system, and each safety harness is connected to the damping safety rope system.

[0009] Preferably, the parachute system includes an inflatable parachute, which includes a main parachute, a connecting air column, and a cushioning air cushion. The connecting air column connects the main parachute and the cushioning air cushion, and the deployed cross-sectional dimension of the main parachute is larger than that of the cushioning air cushion.

[0010] Preferably, the safety harness is connected to the cushioning air cushion, the main umbrella unfolds into a ring shape, and the through hole in the middle of the main umbrella is sized to allow multiple safety harnesses and users wearing safety harnesses to pass through.

[0011] Preferably, the parachute system unfolds in a shape similar to that of a hot air balloon, and a counterweight is provided on the cushioning air cushion.

[0012] Preferably, the damping safety rope system includes a safety buckle and a damping safety rope bearing, with a damping rope wound around the damping safety rope bearing; one end of the damping rope is fastened to one end of the safety buckle, and each of the safety harnesses is fastened to the other end of the safety buckle via the damping safety rope.

[0013] Preferably, the safety buckle has a through hole at the end opposite to its connection with the damping rope, and the damping safety rope passes through the through hole and is fixed by a clamping sleeve.

[0014] Preferably, it is applicable to buildings with a height greater than 30 meters.

[0015] According to the present invention, an escape method for a collective escape device for building fires includes the following steps: Preparation stage: S1, multiple escapees wear safety harnesses; S2, the damping safety rope bearing is fixed, the damping rope on the damping safety rope bearing is led out and fixedly connected to the safety buckle, multiple safety harnesses are connected with connecting ropes, and any safety harness is fixedly connected to the safety buckle through the damping safety rope; Parachute deployment stage: S3, the back is against the windowsill, ensuring the parachute backpack is outside the window; S4, the parachute is inflated until it is fully deployed; Escape stage: S5, the user jumps out of the window and is caught by the parachute and begins to fall until safely landing.

[0016] Preferably, in step S5, during the descent, when the damping rope reaches its limit length, or when the damping rope burns, or when the damping rope overheats, the user can unfasten the safety buckle to separate the damping rope from the user, and the user and the parachute system can continue to fall until they land safely.

[0017] Preferably, the parachute system and the damping safety rope system satisfy the following relationship:

[0018] G people +G parachute =k damping ·v * +k buoyancy ·v *2

[0019] Among them, G people For the weight of all those escaping, G parachute For the weight of the parachute, k damping k is the damping coefficient of the damping safety rope.buoyancy v is the buoyancy coefficient of the parachute. * Design speed;

[0020] After the user is separated from the damping rope, the parachute system satisfies the following relationship:

[0021] G people +G parachute =k buoyancy ·v' 2

[0022] At this point, v'>v * Both speeds are within the safe speed range.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. This invention utilizes a parachute system, a wearable system, and a damping safety rope system in conjunction. By descending a certain distance from a high-rise building using the damping safety rope system and the parachute system, when the damping rope reaches its limit length, or when the damping rope burns or overheats, the user can open the safety buckle to separate from the damping rope and use the parachute system to escape. This enables the collective escape of multiple family members and helps reduce the time required for collective escape.

[0025] 2. This invention connects the safety harness and the safety buckle with a damping rope and a safety cord. The damping rope is connected to the safety buckle, and the safety buckle can be opened to separate it from the damping rope, which helps to improve the convenience of operation for users.

[0026] 3. The present invention uses a parachute system consisting of a main parachute, a cushioning air cushion, and a connecting air column, and sets a counterweight on the cushioning air cushion so that the cushioning air cushion can always be at the bottom and stably support the user, which helps to improve the safety of escape.

[0038] Damped safety rope system 3 Detailed Implementation

[0039] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0040] Example 1

[0041] like Figure 1 As shown, according to the present invention, a collective escape device for building fires includes a wearable system 1, a parachute system 2, and a damping safety rope system 3. The wearable system 1 includes multiple safety harnesses 11, which are connected by connecting ropes 4. One or more safety harnesses 11 are connected to the parachute system 2, and each safety harness 11 is connected to the damping safety rope system 3.

[0042] Specifically, the parachute system 2 includes an inflatable parachute, comprising a main parachute 21, a connecting air column 22, and a cushioning air cushion 23. The connecting air column 22 connects the main parachute 21 and the cushioning air cushion 23, and the deployed cross-sectional dimension of the main parachute 21 is larger than that of the cushioning air cushion 23. Safety harnesses 11 are connected to the cushioning air cushion 23. The main parachute 21 deploys in a ring shape, and the through-hole in the center of the main parachute 21 allows multiple safety harnesses 11 and users wearing the safety harnesses to pass through. The deployed shape of the parachute system 2 approximates that of a hot air balloon, and counterweights are provided on the cushioning air cushion 23.

[0043] By using an inflatable parachute, the user only needs to turn on the inflation switch for the parachute to inflate automatically and fully open.

[0044] It should be noted that the design inspiration for the unfolding shape of the parachute system 2 in this application comes from hot air balloons. The hot air balloon-like shape design ensures that the cushioning air cushion 23 can always be at the bottom and steadily support the user during the descent of the parachute system 2.

[0045] Multiple connecting air columns 22 are evenly distributed around the periphery between the main umbrella 21 and the cushioning air cushion 23. On the one hand, the multiple connecting air columns 22 can simultaneously inflate the main umbrella 21 and the cushioning air cushion 23. On the other hand, the multiple connecting air columns 22 located around the periphery can protect the user during the descent.

[0046] The purpose of the main umbrella 21 unfolding into a ring shape is to allow the user to land on the cushioning air cushion 23 through the through hole in the middle of the ring when jumping from a high building.

[0047] The damping safety rope system 3 includes a safety buckle 32 and a damping safety rope bearing 31, with a damping rope 5 wound around the damping safety rope bearing 31. One end of the damping rope 5 is fastened to one end of the safety buckle 32, and each safety harness 11 is fastened to the other end of the safety buckle 32 via a damping safety rope 6.

[0048] Since the connection method between any safety strap 11 and safety buckle 32 is the same, the connection method between one safety strap 11 and safety hole will be described below: the safety buckle 32 has a through hole at the end opposite to its connection with the damping rope 5, and the damping safety rope 6 passes through the through hole and is fixed by the tight sleeve 7.

[0049] The damping force provided by the damping rope 5 reduces the initial velocity of the user and the parachute system 2 during descent, further ensuring the safety of escape. The damping rope 5 and the safety harness 11 are connected by the safety buckle 32. When the damping rope 5 reaches its maximum length, the user can open the safety buckle 32 to separate from the damping rope 5 and use the parachute system 2 to escape.

[0050] Furthermore, when escaping, it is best for the user to lie on the cushioning air cushion 23 with the safety buckle 32 facing the user, so that the user can easily and quickly unfasten the safety buckle 32.

[0051] Furthermore, the collective escape device of this application is particularly suitable for buildings with a height greater than 30 meters.

[0052] An escape method for a collective escape device used in a building fire, provided by the present invention, includes the following steps:

[0053] Preparation phase:

[0054] S1. Multiple escapees put on their safety harnesses 11.

[0055] S2. Fix the damping safety rope bearing 31, lead out the damping rope 5 on the damping safety rope bearing 31 and fix it to the safety buckle 32, connect multiple safety harnesses 11 with the connecting rope 4, and fix any safety harness 11 to the safety buckle 32 through the damping safety rope 6.

[0056] Parachute opening phase:

[0057] S3. Stand with your back to the windowsill, ensuring that your parachute backpack is outside the window.

[0058] S4. Inflate the parachute until it is fully deployed.

[0059] Escape Phase:

[0060] S5. The user jumps out of the window and is caught by the parachute, beginning the descent until a safe landing. During the descent, if the damping rope 5 reaches its limit length, or if the damping rope 5 burns, or if the damping rope 5 overheats, the user can release the safety buckle 32 to separate the damping rope 5 from the user, and the user and parachute system 2 will continue to fall until a safe landing.

[0061] Parachute system 2 and damped safety rope system 3 satisfy the following relationship:

[0062] G people +G parachute =k damping ·v * +k buoyancy ·v *2

[0063] Among them, G people For the weight of all those escaping, G parachute For the weight of the parachute, k damping k is the damping coefficient of the damping safety rope 6. buoyancy v is the buoyancy coefficient of the parachute. * Design speed;

[0064] After the user is separated from the damping rope 5, the parachute system 2 satisfies the following relationship:

[0065] G people +G parachute =k buoyancy ·v' 2

[0066] At this point, v'>v * Both speeds are within the safe speed range.

[0067] The inflatable parachute, hot air balloon, and damping rope 5 mentioned in this application are all things that can be seen in daily life.

[0068] Example 2

[0069] Based on Embodiment 1, the escape method of the collective escape device for building fire provided by the present invention is applicable to family escape. The number of safety harnesses 11 is the same as the total number of family members. This application uses the example of all family members including the father, mother and children for illustration.

[0070] Escape methods include the following steps:

[0071] Preparation phase:

[0072] S1. Parents should quickly put on their safety harnesses 11 and help the child put on their safety harnesses 11 as well. The father, as the primary operator, should attach a parachute backpack containing an inflatable parachute to his safety harness 11.

[0073] S2. The father is responsible for fixing the bearing of the damping safety rope 6 to a solid surface or column, and leading out the damping rope 5 and securing the buckle; at the same time, the mother is responsible for connecting her and the child's safety harness 11 to the father's safety harness 11 with the connecting rope 4.

[0074] Parents secure their respective damping safety ropes 6 to the safety harnesses 11, and also connect the child's safety harnesses 11 to the damping safety ropes 6.

[0075] Parachute opening phase:

[0076] S3. The father stands with his back against the window (he can sit on the windowsill), ensuring that the entire parachute backpack is outside the window with enough space to open.

[0077] S4. Father pulls the parachute backpack switch, and the inflatable parachute begins to inflate automatically and quickly. Wait for the parachute to fully deploy (it will take up to 10 seconds).

[0078] Escape Phase:

[0079] S5. The father hugs the child, and together with the mother, they lean back and jump out of the window, caught by a parachute, and begin to fall rapidly. When the speed increases to...

[0080] G people +G parachute =k damping ·v * +k buoyancy ·v *2

[0081] When the design speed is reached, the speed no longer increases, and the parachute lands smoothly; where G is the parachute speed. people For the weight of all those escaping, G parachute For the weight of the parachute, k damping k is the damping coefficient of the damping safety rope 6. buoyancy v is the buoyancy coefficient of the parachute. *Design speed;

[0082] If the safety damping rope 5 is not long enough, or if it burns or overheats due to the spread of fire, the father can unfasten the buckle to completely separate the damping safety rope system 3 from the escapee.

[0083] G people +G parachute =k buoyancy ·v' 2

[0084] At this point, v'>v * However, due to design, both speeds are within the safe speed range, ensuring the safe landing of both the parachute and the personnel.

[0085] The collective escape device described in this application allows all family members to quickly operate the equipment during a fire, enabling multiple family members to escape together at once and reducing escape time. Furthermore, parents can lead children, the elderly, or disabled relatives to escape together.
