Description

A smart rescue device Technical Field

[0001] This invention relates to the field of building rescue technology, and more specifically, to an intelligent rescue device. Background Technology

[0002] As cities develop, available land in cities is decreasing. High-rise buildings can effectively save land area, but at the same time, the population density in high-rise buildings is high, and the consequences of fire are very serious. Fire is a major environmental safety accident, which has great destructive power to human life and property.

[0003] A patent document with publication number CN220149162U discloses an aerial fire rescue device for high-rise buildings. This device features a telescopic plate installed on the floor of the rescue work cabin, connected to a hydraulic cylinder and piston rod. During rescue operations, the plate extends via a PLC control panel to serve as a rescue standing platform, resting against windows or balconies. This design ensures no gaps between the rescue work cabin and the rescue point, preventing injuries caused by excessive gaps. A support plate is fixedly connected to the bottom of the rescue work cabin to stabilize the telescopic plate as a rescue standing platform. Guardrails on both sides of the telescopic plate also ensure the safety of rescue personnel and trapped individuals during the rescue process.

[0004] Although the aforementioned aerial fire rescue devices for high-rise buildings can solve the corresponding technical problems, in serious situations, people trapped inside the building can only wait for fire trucks to rescue them, thus missing the best rescue opportunity. Furthermore, due to structural limitations, it is difficult to carry out fire rescues on even taller buildings where ladders cannot reach. Therefore, we propose an intelligent building fire rescue system and an intelligent rescue device.

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Example 1

[0046] As shown in Figures 1-9, an intelligent rescue device according to an embodiment of the present invention includes: a rescue cabin 1, a lifting mechanism 2, a guiding mechanism 3, a soft cable tensioning adjustment mechanism 4, an anti-fall mechanism 5, a central control system 6, and a power supply system 7.

[0047] Among them, rescue cabin 1 is used to evacuate and rescue trapped people in the building, and rescue cabin 1 is located in the shaft of the building and the waiting stairwell;

[0048] The hoisting mechanism 2 is used to move the rescue cabin 1 up and down. The hoisting mechanism 2 is located on the roof of the building, and the rescue cabin 1 is located below the hoisting mechanism 2.

[0051] Among them, the anti-fall mechanism 5 is used to brake the rescue cabin 1 when it stalls, and the anti-fall mechanism 5 is provided on the bottom of both sides of the rescue cabin 1.

[0052] The central control system 6 is used to adjust the working status or parameters of the lifting mechanism 2 and the anti-fall mechanism 5, and is used to connect to the building's fire alarm system. The central control system 6 is located inside the building.

[0053] The power supply system 7 is used to provide power to the lifting mechanism 2, the anti-fall mechanism 5, and the central control system 6, and the power supply system 7 is installed on the roof of the building.

[0054] Example 2

[0055] As shown in Figures 1 and 2, the intelligent rescue device provided in this embodiment differs from that in Embodiment 1 in that:

[0056] The lifting mechanism 2 includes a fixed platform 21, a winch 22, a wire rope 23, and a guide wheel 24. The fixed platform 21 is horizontally installed on the roof of the building. The winch 22 is installed on the top of the fixed platform 21. One end of the wire rope 23 is fixedly wound around the winch 22, and the other end of the wire rope 23 passes through the bottom of the fixed platform 21 and is fixedly connected to the top of the rescue cabin 1 through the rope end assembly. The guide wheel 24 is installed on the top of the fixed platform 21 and is used to guide the wire rope 23. By starting the winch 22, the wire rope 23 can be wound up and down, thereby enabling the vertical movement of the rescue cabin 1.

[0057] Example 3

[0058] As shown in Figures 1, 3, and 4, the intelligent rescue device provided in this embodiment differs from that in Embodiment 2 in that:

[0059] The guiding mechanism 3 includes a guide cable 31, a bracket 32, and a sliding assembly A33. The guide cable 31 is provided at each of the four corners of the outer surface of the rescue cabin 1. The bracket 32 ​​is installed on the top of the fixed platform 21. The top end of the guide cable 31 is fixedly hung on the bracket 32, and the bottom end of the bracket 32 ​​is fixedly connected to the wellbore ground. The top and bottom corners of the rescue cabin 1 are slidably connected to the guide cable 31 through the sliding assembly A33. When the rescue cabin 1 moves up and down by the lifting mechanism 2, the guide cable 31 can guide the rescue cabin 1 and prevent the rescue cabin 1 from swaying when moving up and down, which helps to improve the stability of the rescue cabin 1 when moving up and down.

[0060] The guiding mechanism 3 also includes T-shaped guide rails 34 and sliding components B35. Two T-shaped guide rails 34 are provided between the fixed platform 21 and the shaft floor, symmetrically arranged on both sides of the rescue cabin 1. The top of the T-shaped guide rails 34 is fixedly connected to the fixed platform 21, and the bottom of the T-shaped guide rails 34 is fixedly connected to the shaft floor. The top and bottom sides of the rescue cabin 1 are slidably connected to the T-shaped guide rails 34 through the sliding components B35. When the rescue cabin 1 moves up and down driven by the lifting mechanism 2, the T-shaped guide rails 34 can further guide the rescue cabin 1, further improving the lifting height of the rescue cabin 1. Stability during downward movement; the sliding assembly A33 includes a first mounting bracket 331 mounted on the rescue cabin 1. A linear slider 332 is mounted on the side of the first mounting bracket 331 near the guide cable 31. The inner cavity of the linear slider 332 is provided with a second through hole for the guide cable 31 to pass through. When the rescue cabin 1 moves the sliding assembly A33 up and down, the linear slider 332 can slide on the surface of the guide cable 31 to achieve the guiding operation; the sliding assembly B35 includes a second mounting bracket 351 mounted on the rescue cabin 1. Three pulleys 35 are rotatably connected to one side of the second mounting bracket 351 and slidably connected to the T-shaped guide rail 34. 2. Two pulleys 352 are symmetrically arranged about the center of the T-shaped guide rail 34, and the centerline of the other pulley 352 is on the same plane as the centerline of the T-shaped guide rail 34. When the rescue cabin 1 moves the sliding component B35 up and down, the pulley 352 can roll on the surface of the T-shaped guide rail 34 to achieve guiding operation. Several first supports 36 are fixedly connected between the T-shaped guide rail 34 and the building, and two guide cables 31 near the building are fixedly connected between the two supports 37, which are also fixedly connected between the two supports 31 and the building, and the first supports 36 and the second supports 37 are spaced apart. The first bracket 36 provides auxiliary support for the T-shaped guide rail 34, and the second bracket 37 provides auxiliary support for the two guide cables 31 near the building, which helps to improve the support stability of the first bracket 36 and the two guide cables 31 near the building. The linear slider 332 has an open channel 333 connected to the second through hole on the side of the second bracket 37, and the diameter of the through hole is adapted to the second bracket 37, which effectively avoids the second bracket 37 from blocking the linear slider 332, so as to ensure that the linear slider 332 can move up and down normally on the surface of the guide cables 31.

[0061] Example 4

[0062] As shown in Figures 1 and 5, the intelligent rescue device provided in this embodiment differs from that in Embodiment 3 in that:

[0063] The flexible cable tensioning adjustment mechanism 4 includes a guide sleeve 41, a clamp 42, a stop block 43, and a locking nut 44. Two clamps 42 are symmetrically and movably connected to the upper end of the inner cavity of the guide sleeve 41. The guide flexible cable 31 is movably inserted between the two clamps 42. The stop block 43 is fixedly connected to the upper end of the surface of the guide flexible cable 31 and acts as a block to restrict the upward movement of the clamps 42. The bottom diameter of the clamp 42 is smaller than the top diameter, so that when the guide sleeve 41 moves upward, it can drive the two clamps 42 to move in opposite directions to clamp the guide flexible cable 31. The fixed platform 21 has a first through hole for the guide flexible cable 31 to pass through. The upper part of the inner wall of the guide sleeve 41 has a receiving groove for accommodating the clamps 42. The outer surface of the guide sleeve 41 is slidably connected to the inner wall of the receiving groove, and the inner wall of the first through hole is slidably connected to the outer surface of the guide sleeve 41. The locking nut 44 is threadedly fitted onto the outer surface of the guide sleeve 41. The bottom of the locking nut 44 is rotatably connected to the top of the fixed platform 21 through a bearing. By rotating the locking nut 44, the guide sleeve 41 can be moved upward under the action of the thread, and the guide cable 31 can be pulled upward to adjust the tension of the guide cable 31. The outer surface of the guide sleeve 41 is threadedly fitted with an anti-loosening nut 45, which is located above the locking nut 44. The anti-loosening nut 45 can ensure that the locking nut 44 will not loosen or lose its tightness under vibration.

[0064] Example 5

[0065] As shown in Figures 1, 6, 7, 8, and 9, the intelligent rescue device provided in this embodiment differs from that in Embodiment 4 in that:

[0066] The fall arrestor 5 includes a support assembly 51, an electric telescopic rod 52, a third support 53, a brake assembly 54, and a support 55. The support assembly 51 is mounted on the rescue chamber 1. The electric telescopic rod 52 is mounted on top of the support assembly 51. The third support 53 is fixedly connected to the output end of the electric telescopic rod 52. The brake assembly 54 is movably mounted below the third support 53. A guide cable 31 is movably mounted through the brake assembly 54. The brake assembly 54 is movably mounted within the cavity of the support 55. The support 55 is mounted on the support assembly 51. On one side of rescue cabin 1, a linear velocity sensor is installed to monitor the moving speed of rescue cabin 1. The linear velocity sensor can be a PC420VP-05 model. By activating the electric telescopic rod 52, the brake assembly 54 can be lifted upward, thereby engaging the brake assembly 54 to clamp the guide cable 31 and stop rescue cabin 1, thus preventing the entire rescue cabin 1 from falling downward. The support assembly 51 includes a third mounting bracket 511 fixedly connected to rescue cabin 1. The third mounting bracket 511... An L-shaped plate 512 is fixedly connected to the top, and an electric telescopic rod 52 is installed at the bottom of the inner wall of the L-shaped plate 512. A support 55 is fixedly connected to one side of the outer surface of the L-shaped plate 512. The support assembly 51 forms the mounting base for the electric telescopic rod 52 and the support 55. The brake assembly 54 includes a brake caliper 541 that is movably connected to both sides of the inner cavity of the support 55 and has a wedge-shaped structure. Brake pads 542 are fixedly connected to the opposite sides of the two brake calipers 541. The inclined surfaces of the brake calipers 541 slide along the inclined direction. Connected to the inner wall of the support 55, one side of the brake caliper 541 is horizontally slidably connected to the third bracket 53. When the third bracket 53 drives the brake assembly 54 to move upward, the brake caliper 541 can slide on the inner wall of the support 55, so that the two brake calipers 541 in the inner cavity of the support 55 can move towards each other to achieve the purpose of closing the brake. The inner wall of the brake pad 542 is glued with a rubber pad, which can increase the friction between the brake pad 542 and the guide cable 31, and help improve the stability of the brake assembly 54 when closing the brake.

[0067] Among them, the winch 22, the electric telescopic pole 52 and the linear velocity sensor are all electrically connected to the central control system 6, and the winch 22, the electric telescopic pole 52, the linear velocity sensor and the central control system 6 are all electrically connected to the power supply system 7.

[0068] The working principle of this invention is briefly described below:

[0069] Rescuing trapped personnel: Start the winch 22. The winch 22 winds up or unwinds the wire rope 23, causing the rescue cabin 1 to move upwards or downwards. The rescue cabin 1 drives the sliding components A33 and B35 to move synchronously, causing the linear slider 332 to slide on the surface of the guide cable 31 and the pulley 352 to roll on the surface of the T-shaped guide rail 34 until the rescue cabin 1 moves to the height of the fire point. Then, open the rescue cabin door of the building, allowing the evacuation and rescue of trapped personnel inside the building through the rescue cabin 1, thus completing the rescue operation. During normal operation of the rescue cabin 1, the braking component 54 is... When the linear velocity sensor detects a stall in the rescue cabin 1 while it is in the normally open state, it sends an electrical signal. The central control system 6 receives the electrical signal and controls the electric telescopic rod 52 to start. The output end of the electric telescopic rod 52 drives the third bracket 53, brake caliper 541 and brake pad 542 to move upward synchronously. The brake caliper 541 slides in the inner cavity of the support 55. The brake caliper 541 drives the brake pad 542 to move synchronously, so that the two brake pads 542 in the inner cavity of the support 55 move towards each other, thereby causing the brake assembly 54 to close and clamp the guide cable 31 to stop the rescue cabin 1, thus preventing the entire rescue cabin 1 from falling downward.

[0070] Adjusting the tension of the guide cable 31: Rotate the locking nut 44. Under the action of the thread, the locking nut 44 drives the guide sleeve 41 to move upward in the inner cavity of the first through hole. This causes the two clamping cores 42 in the inner cavity of the guide sleeve 41 to move in opposite directions and clamp the guide cable 31. Continue to rotate the locking nut 44, causing the guide sleeve 41 to continue to move upward. Under the restriction and blocking action of the stop block 43, the guide sleeve 41 drives the clamping cores 42 to move upward synchronously. The clamping cores 42 pull the guide cable 31 upward and tighten it. This completes the adjustment of the tension of the guide cable 31.

[0071] In summary, this intelligent rescue equipment, by adding a rescue cabin 1 and a hoisting mechanism 2 to the building, allows the rescue cabin 1, suspended at a certain location on the building's roof, to be lowered to the rescue cabin entrance at the point of fire during a fire. This enables the evacuation and rescue of trapped personnel within the building, achieving the goal of personnel rescue and ensuring timely assistance to those trapped. It also effectively avoids situations where structural limitations hinder firefighting rescue efforts. Furthermore, by adding a guiding mechanism 3 and a soft cable tensioning adjustment mechanism 4 between the hoisting mechanism 2 and the shaft floor, the equipment guides the rescue cabin 1 as it moves up and down. This allows the rescue cabin 1 to move stably up and down, preventing it from swaying or shaking. By adding an anti-fall mechanism 5 between the rescue cabin 1 and the guide mechanism 3, when the linear velocity sensor detects that the rescue cabin 1 is stalling, it sends an electrical signal. The central control system 6 receives the electrical signal and controls the electric telescopic rod 52 to start. This causes the output end of the electric telescopic rod 52 to drive the third support 53 and the brake assembly 54 to lift upwards. With the cooperation of the support 55, the brake assembly 54 closes and clamps the guide cable 31 to stop the rescue cabin 1, thereby preventing the entire rescue cabin 1 from falling downwards and effectively avoiding secondary injuries to the personnel inside the rescue cabin 1.

However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
