Abstract
Description
Technical Field
[0001] This invention belongs to the field of fire escape equipment technology, specifically relating to an adjustable speed high-rise building escape chamber system based on electromagnetic eddy current damping. Background Technology
[0002] Fire escape in high-rise buildings has always been a major challenge in the field of fire safety. Traditional escape methods such as fire escape stairs, descent devices, and escape slings have obvious limitations. For example, fire escape stairs are easily filled with smoke during a fire, descent devices rely on the user's operating skills and have a single descent speed, and escape slings suffer from problems such as friction heating, wear and aging.
[0003] However, in the event of a fire, people in high-rise buildings need to throw themselves down from the fire escape stairs. These stairs, located inside the building, are easily filled with smoke and heated, resulting in poor safety. Furthermore, escaping via these stairs takes considerable time and increases the risk of secondary injuries from stampedes. Chinese invention patent CN2020107154449 discloses "A High-Rise Escape Channel Based on Electromagnetic Induction." This technology uses a coil wound around the outer wall of the escape tube and connected to an emergency power supply. As the escape capsule falls, it cuts magnetic field lines, creating damping and slowing its speed. If the electromagnetic escape tube is long enough, the escape capsule will eventually reach a stable speed and continue moving. Uniform linear motion serves as a safe escape mechanism. However, this solution relies on an external power source to achieve its damping deceleration function. In the event of a fire in a high-rise building, sudden situations such as circuit burnout and large-scale power outages are highly likely. At this time, the electromagnetic induction deceleration system will lose its power support and will not be able to work properly. Its reliability and stability under extreme escape scenarios will be greatly reduced, making it difficult to continuously ensure the safe escape of personnel. At the same time, its core structure requires a large number of electromagnetic coils to be densely wound on the outer wall of the escape tube, along with corresponding power supply and control components. This not only makes the overall structure complex and difficult to install, but also leads to significantly higher material costs, manufacturing costs, and subsequent maintenance costs, which is not conducive to widespread promotion and application.
[0004] Therefore, to address the aforementioned technical problems, it is necessary to provide an adjustable-speed escape pod system for high-rise buildings based on electromagnetic eddy current damping.

Detailed Implementation
[0027] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0028] like Figures 1 to 5 As shown, an embodiment of the present invention discloses an adjustable-speed high-rise building escape pod system based on electromagnetic eddy current damping, comprising: an escape pod body 1, an escape passage 2, a positioning mechanism 3, a guiding mechanism 4, and a protective mechanism 5. The escape passage 2 is located on the outside of the escape pod body 1, and has multiple adjustment holes, the density of which gradually decreases from top to bottom vertically. The positioning mechanism 3 is located between the escape pod body 1 and the escape passage 2. The guiding mechanism 4 is located on the outside of the escape pod body 1. The protective mechanism 5 is located on the lower side of the escape passage 2.
[0029] The method of using the adjustable-speed high-rise building escape pod system based on electromagnetic eddy current damping is as follows: In the event of a fire, personnel open the escape pod entrance—usually a reinforced sealed door—enter the escape pod 1, close the pod door, and pull the positioning mechanism 3. After the initial lock is released, the escape pod 1 falls freely within the escape passage 2 under the influence of gravity via the guide mechanism 4. Since copper is a good conductor, the escape pod 1 acts as a huge "moving magnetic source." In reality, due to relative motion, the escape pod 1 cuts through the Earth's magnetic field and the weak magnetic field generated by its own charge distribution, and interacts electromagnetically with the escape passage 2. More importantly, the escape pod 1 and the escape passage 2 constitute a "relatively moving conductor-conductor system." According to the law of electromagnetic induction, eddy currents will be induced in the escape passage 2. The magnetic field of these eddy currents interacts with the falling motion of the escape pod 1, generating an upward damping force F_damp. The magnitude of the damping force follows the following simplified formula:
[0030]
[0031] in, The effective conductivity of escape route 2, The equivalent magnetic field strength, The descent speed of escape pod 1, The effective flow area of eddy currents in the aluminum wall is dynamically adjusted by changing the aperture ratio. On floors with high opening ratios, Small, low damping force, suitable for floors with low open area ratio. The large size of the escape chamber 1 results in a large damping force, thus the descent speed of the escape chamber 1 will automatically adapt to the damping environment of the escape passage 2, being faster at higher elevations and slower at lower elevations.
[0032] As the escape pod 1 approaches the first floor, the outer wall of the escape passage 2 becomes almost solid, the damping force reaches its peak, and the speed of the escape pod 1 is greatly suppressed. Ultimately, the target can enter the protection mechanism 5 at a relatively low speed of 3-5 m / s, and complete a safe landing.
[0033] It achieves complete passivity and reliability: requiring no external power or mechanical force, it operates solely based on gravity and the laws of electromagnetic physics, ensuring absolute reliability during power outages and fires. Intelligent speed control: Through an innovative gradient-aperture channel design, it achieves intelligent speed regulation, allowing for "high-speed passage through dangerous areas and low-speed safe landing," resolving the contradiction of constant damping devices being "either too slow throughout or too fast at the end." Frictionless and maintenance-free: The damping force comes from the electromagnetic field; there is no physical contact between the escape chamber 1 and the escape channel 2, completely avoiding friction loss, heat generation, and lubrication issues, resulting in an extremely long lifespan. Highly versatile: It has no special requirements regarding the user's physical strength or age, is simple to operate, and has a wide range of applications.
[0034] like Figures 1 to 4 As shown, the escape pod 1 is equipped with an escape pod seat 11, a small oxygen cylinder 12, and lighting equipment 13. The escape pod seat 11 is designed to fit the human physiological structure, disperse impact loads, absorb the impact force during the fall, collision, and bumping of the escape pod 1, protect the spine, head, and internal organs, and improve seating stability and comfort. The escape pod seat 11 is equipped with a seat belt 111, which can reliably secure the person to the escape pod seat 11, preventing the person from being thrown around during the movement of the escape pod 1 or an impact. Collision-resistant devices reduce the risk of secondary injuries. The small oxygen cylinder 12 is equipped with an oxygen mask 121. The oxygen mask 121 can provide emergency oxygen supply to personnel in harsh environments such as oxygen deficiency, presence of toxic and harmful gases, smoke or dust in the escape chamber 1, ensuring breathing safety and maintaining vital signs during escape and waiting for rescue. The lighting device 13 can provide emergency lighting to illuminate the environment and operating parts of the escape chamber 1 in dark, power outage, or smoke-obstructed vision conditions, making it easier for personnel to check the status, operate the equipment and carry out self-rescue.
[0035] like Figures 1 to 3 As shown, the escape chamber body 1 is made of high-purity electrolytic copper, and the escape passage 2 is made of pure aluminum, forming a relatively moving conductor pair between the escape chamber body 1 and the escape passage 2. A ventilation fan 21 is installed on the upper side of the escape passage 2. The ventilation fan 21 can supply fresh air into the escape passage 2 when the fire alarm is activated, preventing smoke intrusion. The escape chamber body 1 can be a cylindrical or elliptical cylindrical sealed chamber, with its main structure made of high-purity electrolytic copper (T2 copper). Copper has excellent electrical conductivity, with a conductivity of approximately 5.8 × 10⁻⁶. 7 S / m is the key to generating strong eddy current damping. The wall thickness of the escape chamber body 1 is calculated to be between 10 and 20 mm, which can ensure sufficient structural strength and eddy current path without being too heavy.
[0036] like Figures 1 to 3 As shown, the positioning mechanism 3 includes: a positioning fixing ring 31, a positioning follower ring 32, multiple pairs of positioning locking beads 33, and a positioning mounting pin 34. The positioning fixing ring 31 is located within the escape passage 2. The positioning fixing ring 31 cooperates with the positioning locking beads 33 to position and fix the positioning follower ring 32. The positioning follower ring 32 is located on the upper side of the escape chamber body 1 and can be engaged by the positioning locking beads 33, thus fixing the escape chamber body 1. Multiple pairs of positioning locking beads 33 are located within the positioning follower ring 32. The positioning mounting pin 34 is located within the positioning follower ring 32 and can mutually compress with the positioning locking beads 33. This not only achieves the engagement of the positioning locking beads 33 with the positioning follower ring 32 but also fixes the positioning mounting pin 34. When not subjected to external force, the positioning mounting pin 34 can always compress the positioning locking beads 33. The positioning and fixing ring 31 is fixedly connected to the escape passage 2, and the positioning and following ring 32 is fixedly connected to the escape chamber body 1. Both the positioning and following ring 32 and the positioning and fixing ring 31 have positioning grooves that match the positioning locking beads 33. The positioning mounting pin 34 is slidably disposed within the positioning and following ring 32. A pair of positioning connecting ropes 341 are installed between the positioning mounting pin 34 and the escape passage 2 to fix the position of the positioning mounting pin 34, reducing the chance of the positioning mounting pin 34 falling off and preventing injury to the user.
[0037] like Figures 1 to 5 As shown, the guiding mechanism 4 includes multiple pairs of guide support wheels 41 and multiple pairs of guide rails 42. The multiple pairs of guide support wheels 41 are mounted on the escape pod body 1. The guide support wheels 41 are positioned to roll along the escape channel 2, limiting the distance between the escape channel 2 and the escape pod body 1 and preventing collisions. The multiple pairs of guide rails 42 are positioned within the escape channel 2 and are matched with the guide support wheels 41. The guide rails 42 guide and position the guide support wheels 41.
[0038] like Figures 1 to 2 As shown, the protective mechanism 5 includes a protective compartment 51 and a protective pad 52. The protective compartment 51 is located on the lower side of the escape passage 2, and its location facilitates the installation of the protective pad 52. The protective pad 52 is located inside the protective compartment 51. The protective pad 52 can cushion and protect the escape compartment 1, absorbing the remaining kinetic energy when the escape compartment 1 finally stops, ensuring that the overload experienced by passengers is within a safe range. The interior of the pad 52 is filled with multi-level cushioning materials, such as high-elasticity foam and rubber springs.
