Description

Technical Field

[0001] This invention relates to the field of high-rise building rescue equipment technology, specifically a high-rise building fire rescue device. Background Technology

[0002] With the acceleration of urbanization, high-rise and super high-rise buildings (generally referring to high-rise residential buildings with a height of ≥27m, public buildings with a height of ≥50m, and super high-rise buildings with a height of over 100m) have become a core component of urban space. While these buildings improve land use efficiency and meet the needs of population concentration, their complex structures, prominent heights, and dense populations also pose severe challenges to fire emergency rescue. Traditional rescue methods are gradually revealing their insurmountable limitations, creating an urgent need for new and efficient rescue devices.

[0003] Traditional fire ladder trucks typically have a lifting height limited to 50-60m (approximately 15-20 stories), making them completely ineffective for skyscrapers exceeding 100m in height. Helicopter rescue is heavily restricted by weather conditions and surrounding airspace, and it's difficult to accurately land on the facade of high-rise buildings, limiting its use to extreme scenarios. When a fire occurs in the mid-to-high floors (above the 11th floor), external rescue forces struggle to reach the trapped individuals quickly, making evacuation primarily reliant on internal self-rescue.

[0004] Stairwells, elevator shafts, and other vertical passages in high-rise buildings can easily become "chimneys" for the spread of fire smoke. High-temperature toxic fumes (carbon monoxide, hydrogen cyanide, etc.) can spread rapidly and fill evacuation routes in a short time, causing people to be poisoned and suffocated. This is the main reason for more than 80% of casualties in fires.

[0005] Patent CN108671430A discloses a fire rescue device for high-rise buildings, which adopts a structure of "fixed frame, telescopic rod and single rope". Although it achieves separate storage and instant access, it has multiple safety hazards: First, it lacks safety redundancy, with a single rope bearing the load and no braking protection, resulting in a high risk of rope breakage and overspeed. Second, it has poor adaptability to different groups of people, only meeting the needs of healthy adults. The elderly, children and disabled people cannot operate it independently, and there is no structure to fix unconscious people.

[0006] In summary, existing high-rise building fire rescue technologies have significant shortcomings in terms of safety redundancy and compatibility with all population groups, making them unable to effectively address the complex working conditions and diverse needs of fires in super high-rise buildings. With the continuous increase in the number of super high-rise buildings, the urgency and importance of fire rescue are becoming increasingly prominent, necessitating the development of a high-rise building fire rescue device.

[0031] An extension plate is fixedly connected to the upper surface of the base bracket, and the upper surface of the extension plate is flush with the lower inner wall of the storage slot.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] (1) A fire rescue device for high-rise buildings, wherein the escape chamber is embedded in the building wall and residents can enter the chamber from their own homes. Two main load-bearing ropes are hoisted below the winch as the main load-bearing ropes and residents can connect them to the vehicle when escaping. The vehicle is mainly guided by four ring-shaped guide ropes of two sets of rope mechanisms. The safety redundancy coefficient is improved by the cooperation of the guide ropes and the main load-bearing ropes.

[0034] (2) A high-rise building fire rescue device, wherein the pallet mechanism is driven by the cable buckle mechanism to circulate between floors along the guide rope; after the bottom of the cabin is connected, it can be continuously transported to the ground with the pallet mechanism. After the cabin transfer mechanism is removed from the pallet mechanism on the ground, the pallet mechanisms on the two sets of rope mechanisms are separated and put back into use under the circulation of the guide rope. There is no need to wait for the single rescue to be completed and reset. It supports multiple sets of cabin transfer mechanisms to be connected in sequence and continuously evacuated, effectively dealing with the scenario of densely populated high-rise buildings and groups trapped, and greatly increasing the number of people rescued per unit time.

[0035] (3) A fire rescue device for high-rise buildings, in which the escaping residents enter the bottom of the cabin through the slot. Initially, the end of the gear corresponding to the second tooth slot that is away from the first tooth slot is in an unloaded state, which provides a safe operating space for the residents to enter the bottom of the cabin, avoids the risk of collision caused by accidental activation when the personnel have not completed the access, and allows the residents to have enough time to complete the preparation work such as securing themselves and confirming their status, thereby enhancing the psychological sense of security during the escape process.

[0036] (4) A fire rescue device for high-rise buildings, in which the resident manually pushes the transfer mechanism outward so that the gear contacts the second tooth and is in a locked state. At this time, the locking block moves forward into the space where the first rescue component is located. When the two trays are simultaneously supported by the locking block, the motor is energized by the sensor. The motor is energized only when the rated load requirement is met, avoiding the risks caused by accidental contact or no-load start-up. It meets the high safety standards of fire-fighting personnel equipment and improves the load-bearing safety.

[0037] (5) A fire rescue device for high-rise buildings, wherein the gear meshes with the second tooth and the first tooth, thereby actively pushing the transfer mechanism onto the pallet mechanism by electricity. The electric drive responds quickly, significantly shortening the time from when the resident enters the transfer mechanism to when the connection to the pallet mechanism is completed. Especially in the scenario where fire spreads rapidly in middle and high floors, it can reserve more escape time for subsequent residents and effectively reduce the risk of fire escape.

[0038] (6) A fire rescue device for high-rise buildings, wherein when the building is high-rise, a roof is erected above the bottom of the cabin to ensure the protection of the cabin transfer mechanism as much as possible; when the building is in the middle or lower floors, no roof is erected and residents can escape through the bottom of the cabin and the support plate mechanism via a rope mechanism; in addition, according to the residents' own choice, when the bottom of the cabin is moved outward and the locking block only supports the support plate mechanism on one side, young and middle-aged residents can use the bottom of the cabin as a "stepping stone" by fastening the main load-bearing rope to the buckle hole and themselves, and directly descend between floors through a single support plate mechanism. Residents can flexibly choose the escape mode within a safe range according to their own choice, thereby improving the efficiency of mass rescue.

[0039] (7) A fire rescue device for high-rise buildings, wherein when a single sensor senses the pallet mechanism, the first cylinder and the second cylinder are activated simultaneously; the switch clamp extends outward to contact the low-gear switch corresponding to the cable drum, thereby lowering the rope device to the low gear; the safety plate extends outward to support the pallet, first setting the single pallet mechanism, and then waiting for the pallet mechanism of another set of rope mechanisms to be set; by adjusting the cable drum to the low gear through the switch clamp, the connection between the pallet mechanism and the rope mechanism can be released, and then the safety plate supports the pallet mechanism, thereby further improving the access safety of the transfer mechanism.

[0040] (8) A fire rescue device for high-rise buildings, in which the resident escapes by sliding down a rope mechanism through a transfer mechanism and a support plate mechanism. During the return of the safety plate, the resident on the transfer mechanism can choose whether to press the high-speed switch to adjust the speed. If the high-speed switch is pressed, the transfer mechanism will slowly descend under the drive of the guide rope. If the high-speed switch is not pressed, the transfer mechanism will slowly slide down along the guide rope while the guide rope moves, thereby increasing the escape speed and improving the rescue flexibility.

[0041] (9) A fire rescue device for high-rise buildings, which, through the design of the top block, can support the upper transfer mechanism when waiting for another pallet mechanism to be positioned, so as to avoid the upper transfer mechanism from pressing down and causing danger. Then, the residents of this floor need to manually pull back the transfer mechanism and wait for the upper transfer mechanism to pass before waiting again. The existence of the top block can further avoid the danger of escape and further improve the safety of escape. Attached Figure Description

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 10 , Figure 11 , Figure 12 A high-rise building fire rescue device includes a first rescue component located outside the building and a second rescue component located inside the building, as well as a transfer mechanism 6 that can move between the first rescue component and the second rescue component;

[0059] The first rescue component includes two symmetrically separated rope mechanisms 1. Each rope mechanism 1 includes two circular guide ropes 101. The end of each guide rope 101 is connected to an electric winch with a power compartment 102. The top power compartment 102 is installed on the top of the building, and the bottom power compartment 102 is installed at the bottom of the building.

[0060] Each rope mechanism 1 is equipped with a rope buckle mechanism 2. The rope buckle mechanism 2 includes two rope cylinders 201 that are respectively sleeved on the guide rope 101. A rope attaching device 202 that fits the guide rope 101 is fixedly embedded in the inner side of the middle of the rope cylinder 201. A connecting rod 203 is fixedly connected between the two rope cylinders 201.

[0061] Each buckle mechanism 2 is provided with a support plate mechanism 3. The support plate mechanism 3 includes a support plate 301 with a fixed connecting rod 203. A first plate groove 302 is opened on the upper surface of the support plate 301. A seat groove 303 is evenly and equidistantly opened on the lower inner wall of the first plate groove 302. Buckle holes 304 are evenly and equidistantly opened through the lower edge of the first plate groove 302.

[0062] The second rescue component includes a space mechanism 4 and an extension mechanism 5;

[0063] The extension mechanism 5 includes an extension plate 501, a second plate groove 502 is provided on the upper surface of the extension plate 501, and a locking groove 503 is provided through the middle of the lower wall of the second plate groove 502.

[0064] The cabin transfer mechanism 6 includes a cabin bottom 601 adapted to the first plate groove 302 and the second plate groove 502. A locking bar 603 adapted to the sliding lock groove 503 is fixedly connected to the middle of the lower surface of the cabin bottom 601. A locking block 604 adapted to the sliding lock groove 503 is fixedly connected to the outer end of the locking bar 603.

[0065] Please see Figure 3 Each loop of guide rope 101 is fixedly connected to a rope buckle 103 at its joint.

[0066] Please see Figure 5 A high-range switch 204 is fixedly embedded in the upper end face of a cable drum 201, and a low-range switch 205 is fixedly embedded in the lower end face of a cable drum 201. In the default state of the cable device 202, the cable drum 201 is connected to the guide rope 101 at a medium-range force, meaning the cable drum 201 can move with the guide rope 101 under the medium-range condition of the cable device 202. At this time, external force can block the cable drum 201, making it easy for the cable drum 201 and the guide rope 101 to move relative to each other. Activating the high-range switch 204 puts the cable device 202 at a high-range, meaning the cable drum 201 can move with the guide rope 101 under the high-range condition of the cable device 202, at which time external force cannot make the cable drum 201 and the guide rope 101 move relative to each other. Activating the low-range switch 205 puts the cable device 202 at a low-range, meaning the cable drum 201 can not move with the guide rope 101 under the low-range condition of the cable device 202.

[0067] Please see Figure 4 , Figure 10 , Figure 11 , Figure 12 , Figure 13There is a gap between the two trays 301 that matches the locking groove 503;

[0077] Please see Figure 7 , Figure 8 , Figure 9 , Figure 14The space mechanism 4 includes an escape pod 401 embedded in the building wall, and the outer side of the escape pod 401 is provided with a slot 402;

[0078] A winch 403 is fixedly embedded in the middle of the upper inner wall of the silo 402, and two main load-bearing ropes 404 are wound inside the winch 403.

[0079] An escape chamber 401 is fixedly connected to a spray chamber 405 located above the chamber 402 on its outer side; anchor points 410 are respectively provided at both ends of the spray chamber 405 to be fixed to the escape chamber 401, and a pull rope 411 is fixedly connected between the anchor points 410 and the railing 504.

Above each fire door 407, there is a water tank 408 that is embedded in the escape capsule 401. Below the water tank 408, there are sprinkler pipes 409 that are connected to the inner and outer sides of the corresponding fire door 407.

[0081] The outer side of the escape capsule 401 is fixedly connected to a bottom support 412 located below the capsule 402. The upper surface of the bottom support 412 is provided with sliding grooves 413 on both sides. Safety plates 414 corresponding to the support plate 301 are fitted and inserted into the sliding grooves 413. The inner end of each safety plate 414 is fixedly connected to a first cylinder 415 that is fitted into the escape capsule 401. The two sides of the bottom support 412 are respectively provided with second cylinders 416 that are fixedly connected to the escape capsule 401. The output end of the second cylinder 416 is fixedly connected to a switch clip 417 corresponding to the cable cylinder 201.

[0082] The upper surface of the bottom bracket 412 is fixedly connected to the extension plate 501, and the upper surface of the extension plate 501 is flush with the lower inner wall of the storage groove 402.

[0083] The working principle of this invention is as follows:

[0084] Escape chamber 401 is embedded in the building wall. Residents can enter the chamber 402 from their own homes. Two main load-bearing ropes 404 suspended below the winch 403 serve as the main load-bearing ropes. Residents can connect them to the vehicle when escaping. The vehicle is mainly guided by four ring-shaped guide ropes 101 of two sets of rope mechanisms 1. The safety redundancy factor is improved through the cooperation of the guide ropes 101 and the main load-bearing ropes 404.

[0085] After a fire alarm is triggered, the electric winch inside the power compartment 102 is automatically activated, causing the four circular guide ropes 101 to rotate slowly. The pallet mechanism 3, driven by the cable buckle mechanism 2, circulates between floors along the guide ropes 101. After the bottom compartment 601 is connected, it can be continuously transported to the ground with the pallet mechanism 3. After the transfer mechanism 6 is removed from the pallet mechanism 3 on the ground, the pallet mechanisms 3 on the two sets of rope mechanisms 1 are separated and put back into use under the circulation of the guide ropes 101. There is no need to wait for the reset after a single rescue is completed. It supports the sequential connection and continuous evacuation of multiple sets of transfer mechanisms 6, effectively dealing with scenarios of dense crowds and group entrapment in high-rise buildings, and greatly increasing the number of people rescued per unit time.

[0086] Escaped residents enter the bottom compartment 601 through the slot 402. Initially, the end of the gear 610 corresponding to the second tooth groove 505 away from the first tooth groove 305 is in an unloaded state, reserving safe operating space for residents to enter the bottom compartment 601, avoiding the risk of collision caused by accidental activation before personnel access is completed, and allowing residents sufficient time to complete preparations such as securing themselves and confirming their status, thereby enhancing their psychological sense of security during the escape process.

[0087] The resident manually pushes the transfer mechanism 6 outward, causing the gear 610 to engage with the second tooth 506 and be in a locked state. At this time, the locking block 604 moves forward into the space where the first rescue component is located. When the two pallets 301 are simultaneously supported by the locking block 604, the motor 609 is energized by the sensor 607. The motor 609 is energized only when the rated load requirement is met, avoiding the risks caused by accidental contact or no-load start-up. This meets the high safety standards of fire-fighting personnel-carrying equipment and improves load-bearing safety.

[0088] At this time, the resident presses the lever 613 to activate the start button 611, causing the gear 610 to rotate. The gear 610 engages with the second tooth 506 and the first tooth 306, thereby actively pushing the transfer mechanism 6 onto the pallet mechanism 3 via electricity. The electric drive provides a fast response, significantly shortening the time from when the resident enters the transfer mechanism 6 to when the connection to the pallet mechanism 3 is completed. Especially in scenarios where fires spread rapidly in mid-to-high-rise buildings, this can reserve more escape time for subsequent residents and effectively reduce the risk of fire escape.

[0089] Depending on the floor height, residents can choose their own escape vehicle. On higher floors, a roof 616 is erected above the bottom 601 to ensure the safety of the transfer mechanism 6 as much as possible. On lower floors, the roof 616 is not erected, and residents escape via the bottom 601 to the pallet mechanism 3 and the rope mechanism 1. Alternatively, depending on the residents' choice, when the bottom 601 is moved outward and the locking block 604 only supports the pallet mechanism 3 on one side, young and middle-aged residents can use the bottom 601 as a "stepping stone" to use the main load-bearing rope 404 to fasten it to the buckle hole 304 and themselves, and descend directly between floors via a single pallet mechanism 3. Residents can flexibly choose their escape mode within a safe range, improving the efficiency of mass rescue.

[0090] When using the transfer mechanism 6 for escape, the outward-moving locking block 604 may initially contact only a single pallet mechanism 3. When the single sensor 607 senses the pallet mechanism 3, the first cylinder 415 and the second cylinder 416 are activated simultaneously. The switch clamp 417 extends outward to contact the low-position switch 205 corresponding to the rope cylinder 201, thereby lowering the rope device 202 to the low position. The safety plate 414 extends outward to support the pallet 301, first positioning the single pallet mechanism 3, and then waiting for the pallet mechanism 3 of another set of rope mechanisms 1 to be positioned. Adjusting the rope cylinder 201 to the low position through the switch clamp 417 can disconnect the connection between the pallet mechanism 3 and the rope mechanism 1. Then, the safety plate 414 supports the pallet mechanism 3, thereby further improving the access safety of the transfer mechanism 6.

[0091] After both pallet mechanisms 3 are in position, the starting gear 610 drives the bottom 601 into the first plate groove 302. Finally, the locking block 604 enters between the outer pallets 301 to release the sensor 607 from sensing the lower wall of the first plate groove 302. The switch clamp 417 returns to its original position, causing the cable cylinder 201 to enter the default medium mode. At the same time, the safety plate 414 returns to its original position, allowing escape by sliding down the rope mechanism 1 through the transfer mechanism 6 and the pallet mechanism 3. During the return of the safety plate 414, the occupant on the transfer mechanism 6 can choose whether to press the high-speed switch 204 to adjust the speed. If the high-speed switch 204 is pressed, the transfer mechanism 6 will descend slowly under the drive of the guide rope 101. If the high-speed switch 204 is not pressed, the transfer mechanism 6 will slide down slowly along the guide rope 101 while the guide rope 101 moves, increasing the escape speed and improving the flexibility of the rescue.

[0092] The top block 606 is designed so that when waiting for another pallet mechanism 3 to be positioned, if the upper transfer mechanism 6 slides down along the rope mechanism 1, the top block 606 can provide support to prevent the upper transfer mechanism 6 from pressing down and causing danger. Then, the residents of this floor need to manually pull back the transfer mechanism 6 and wait for the upper transfer mechanism 6 to pass before waiting again. The existence of the top block 606 can further avoid escape danger and further improve escape safety.

[0093] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
