Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, in particular to a high-rise fire fighting hanging basket device. Background Art

[0002] With the acceleration of urbanization, high-rise buildings are becoming increasingly popular in modern cities. However, fires in high-rise buildings have the characteristics of rapid fire spread, difficult evacuation, and limited rescue, which seriously threaten the safety of people's lives and property.

[0003] At present, my country's "Code for Fire Protection Design of Buildings" has formulated relevant requirements for fire safety in high-rise buildings: residential buildings with a building height of more than 100 meters must be equipped with automatic fire extinguishing systems and automatic fire alarm systems; residential buildings with a building height between 54 meters and 100 meters are required to install automatic fire alarm systems in public areas, and it is recommended to install fire detectors in the suites; high-rise residential buildings with a building height of less than 54 meters are recommended to install automatic fire alarm systems in public areas, and they must be installed if linkage control of fire-fighting facilities is required. In addition, the public areas of all high-rise residential buildings should be equipped with fire alarm devices or emergency broadcast systems with voice functions.

[0004] However, the current regulations have obvious deficiencies: for high-rise buildings with a building height of 25 to 100 meters, especially residential buildings, there is no mandatory requirement to install an automatic fire extinguishing system. This regulatory gap makes it difficult to effectively control such buildings when a fire occurs, which can easily cause heavy casualties and property losses. Traditional firefighting and rescue equipment, such as fire truck ladders and aerial work platforms, are often subject to multiple factors when dealing with such high-rise fires: first, the working height of the equipment itself is limited; second, urban road congestion affects the arrival of rescue vehicles at the scene; third, the surrounding environment of the building limits the working space. These factors together make it difficult for traditional firefighting and rescue methods to meet the growing firefighting needs of high-rise buildings.

[0005] Especially in the actual rescue process, the best time for fire fighting is greatly delayed because fire trucks cannot reach the fire scene in time or cannot effectively carry out operations due to obstacles such as parking and greening facilities around the building. These problems have been fully confirmed in major fire accidents in many cities in my country, highlighting the urgency of developing new high-rise building fire rescue equipment. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a high-rise fire fighting hanging basket device which breaks through the limitations of traditional fire fighting equipment in terms of operating height and space.

Detailed Description of the Preferred Embodiments

[0025] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0026] The high-rise firefighting hanging basket device described in this embodiment aims to break through the limitations of traditional firefighting equipment in terms of operating height and space. By designing a telescopic mechanism on the top of a high-rise building, the hanging basket body can be stably lifted and lowered to accurately reach the predetermined floor, thereby efficiently carrying out firefighting and rescue operations. Figures 1 to 4 As shown, the device includes a hanging basket body 10, fire fighting equipment 20, a driving mechanism 30 and a telescopic mechanism 40.

[0027] The hanging basket body 10 serves as a supporting platform for the fire-fighting equipment 20. In the present embodiment, the hanging basket body 10 is made of a high-strength lightweight aluminum alloy material, ensuring that while meeting the load-bearing requirements, the overall weight is reduced as much as possible, thereby reducing the burden on the driving mechanism 30. The fire-fighting equipment 20 can be a device that sprays a variety of fire-extinguishing agents such as water, foam, and dry powder through a high-pressure nozzle to meet the fire-fighting needs in different scenarios.

[0028] The driving mechanism 30 is arranged on the top of the building, and provides a power source for the telescopic mechanism 40. The upper end of the telescopic mechanism 40 is connected to the driving mechanism 30, and the lower end is connected to the hanging basket body 10. In this embodiment, the telescopic mechanism 40 includes at least two scissor-type guide mechanisms 41 arranged in parallel in the vertical direction, and at least one rigid chain 42 is arranged between adjacent scissor-type guide mechanisms 41. Specifically, the scissor-type guide mechanism 41 is composed of a plurality of groups of hinged scissor arms to form a scissors-like structure, and its main function is to provide guidance and support for the hanging basket body 10 to ensure that it does not shake or tilt during the lifting process; and the rigid chain 42 is a special chain structure, which will be rigid when stretched, and can withstand greater pressure without bending or breaking, thereby ensuring the safe lifting of the hanging basket.

[0029] In this embodiment, the power output end of the driving mechanism 30 is connected to the rigid chain 42 for driving and adjusting the extension length of the rigid chain 42, so as to drive the hanging basket body 10 to rise and fall to the target floor in the vertical direction. When the driving mechanism 30 is started, the rigid chain 42 will be driven to extend downward, thereby driving the hanging basket body 10 to descend in the vertical direction. At the same time, the scissor-type guide mechanism 41 will also extend to provide stable support and guidance for the hanging basket body 10; conversely, when the driving mechanism 30 rotates in the opposite direction, the rigid chain 42 will shrink upward, thereby driving the hanging basket body 10 to rise and reset. In the above manner, the hanging basket body 10 can be smoothly lifted and lowered on the facade of a high-rise building to reach the target floor.

[0030] Specifically, Figure 1 , Figure 2As shown, the driving mechanism 30 includes a boom 31 and a driving motor 32; two chain boxes 33 extending along the length direction of the boom 31 and arranged in parallel are provided on the boom 31, and the driving motor 32 is arranged at the distal end of the boom 31 and between the two chain boxes 33; the driving motor 32 is in transmission connection with the sprockets in the chain boxes 33 through a double-shaft transmission mechanism, two rigid chains 42 are provided and are respectively matched with the corresponding chain boxes 33, and the top end of each rigid chain 42 extends into the corresponding chain box 33 and meshes with the sprocket.

[0031] During specific implementation, a track moving mechanism 50 capable of rotating and translating is arranged on the top of the building, and the boom 31 is firmly fixed on the track moving mechanism 50 through high-strength bolts to ensure its sufficient load-bearing capacity and stability. The length of the boom 31 usually extends beyond the edge of the building and needs to be able to cover most areas of the building facade. The driving motor 32 adopts a high-performance servo motor, which has precise speed regulation and positioning capabilities and can provide a smooth and reliable power output for the telescopic mechanism 40.

[0032] In practical applications, as Figure 3 shown, when a fire breaks out in a high-rise building, after receiving the fire alarm signal, the control system will automatically start the track moving mechanism 50, or manually control the boom 31 to accurately move to the position corresponding to the fire floor. Then, according to the height of the fire floor, the driving motor 32 accurately adjusts the extension length of the telescopic mechanism 40 to accurately align the height of the hanging basket body 10 with the window of the target floor. Subsequently, the fire-fighting equipment 20 on the hanging basket body 10 sprays fire extinguishing agent into the room, thereby realizing the rapid and efficient extinguishment of the high-rise building fire and avoiding the situation where it is impossible to effectively carry out operations due to the obstruction of facilities such as parking and greening around the building.

[0033] In some embodiments, as Figure 1 、 Figure 4 shown, the scissor-type guiding mechanism 41 includes a plurality of scissor units hinged in sequence, and each scissor unit includes two scissor arms 411 arranged in a cross shape and hinged through a hinge shaft; in this embodiment, the scissor arms 411 are usually made of high-strength alloy steel material to ensure its sufficient load-bearing capacity and bending stiffness. First connecting rods 412 are provided at the outer ends of adjacent two hinge shafts on the same horizontal plane, and both ends of the two first connecting rods 412 on the same horizontal plane are connected through second connecting rods 413; the first connecting rods 412, the second connecting rods 413 and the scissor unit enclose a guiding space for accommodating the rigid chain 42.

[0034] In this way, the first connecting rod 412 and the second connecting rod 413 together form a stable frame structure. Each frame structure and the scissor unit cooperate to enclose a guiding space for accommodating the rigid chain 42. This can not only effectively protect the rigid chain 42 from damage by the external environment and extend its service life, but also accurately guide the rigid chain 42 to move along a predetermined trajectory, preventing it from shifting or bending, thereby ensuring the smoothness and accuracy of the lifting movement of the hanging basket body 10.

[0035] In some embodiments, as Figure 1 shown, a hanging seat 34 is provided at the distal end of the boom 31. The hanging seat 34 is disposed opposite to the hanging basket body 10. A guiding hole for the rigid chain 42 to pass through is provided on the hanging seat 34. The upper end of the scissor-type guiding mechanism 41 is fixedly connected to the hanging seat 34, and the lower end is fixedly connected to the hanging basket body 10. Specifically, the guiding hole can accurately guide the movement trajectory of the rigid chain 42 to avoid friction or interference with other components. Fixing the upper end of the scissor-type guiding mechanism 41 to the hanging seat 34 and the lower end to the hanging basket body 10 can not only facilitate the installation of the scissor-type guiding mechanism 41 on the boom 31, but also closely combine the scissor-type guiding mechanism 41 with the hanging basket body 10 to form an integral whole, thereby effectively dispersing the load and improving the strength and stiffness of the overall structure.

[0036] In some embodiments, as Figure 1 、 Figure 2 、 Figure 4 shown, the fire-fighting equipment 20 includes a window-breaking device 21 and a fire-extinguishing device 22; the window-breaking device 21 is used to perform a window-breaking operation when the hanging basket body 10 reaches the target floor, and the fire-extinguishing device 22 is used to spray a fire extinguishing agent into the building interior through the opening formed after breaking the window. The window-breaking device 21 is configured to immediately and automatically perform a window-breaking operation after the hanging basket body 10 safely and stably reaches the target floor, creating favorable conditions for subsequent fire-fighting operations; and the fire-extinguishing device 22 is designed to be able to accurately spray a fire extinguishing agent into the building interior through the opening formed after breaking the window to quickly control and extinguish the fire source. In specific implementation, the window-breaking device 21 can select various different types, for example, impact type, cutting type, blasting type, etc., and can be flexibly configured according to actual needs; and the fire-extinguishing device 22 can adopt a high-pressure water gun, a foam sprayer or a dry powder sprayer, etc., to meet the fire-fighting requirements for different types of fires.

[0037] In a specific embodiment, as Figure 1 、 Figure 4As shown, the window-breaking device 21 includes a robotic arm 211 and a firing pin 212 provided at the end of the robotic arm 211. The firing pin 212 is provided with a conical needle tip. The fire extinguishing device 22 is a high-pressure nozzle provided at the end of the robotic arm 211.

[0038] During specific implementation, a water tank 222 is provided on the rail moving mechanism 50. The high-pressure nozzle, i.e., the fire extinguishing device 22, is connected to the water tank through a water supply pipe to spray fire-fighting water at a high pressure to a farther distance and cover a larger area, thereby effectively controlling the spread of the fire. The robotic arm 211 preferably adopts a six-degree-of-freedom design, with high flexibility and motion accuracy, and can precisely control the position and posture of the firing pin 212, so as to achieve precise window breaking for different types and positions of windows. In addition, in this embodiment, in order to ensure the water supply demand of the high-pressure nozzle, a water tank 222 is also provided on the rail moving mechanism 50, and the high-pressure nozzle, i.e., the fire extinguishing device 22, is connected to the water tank 222 through a water supply pipe. In order to avoid potential interference between the water supply pipe and the other components of the fire-fighting hanging basket device, a hose reel 221 is installed on the water tank 222. Through the hose reel 221, the water supply pipe can be adaptively retracted and released according to the lifting and lowering of the hanging basket body 10, thereby effectively avoiding interference between the water supply pipe and other components and ensuring the smooth and reliable operation of the entire fire-fighting hanging basket device.

[0039] In some embodiments, as Figure 4 shown, a pneumatic suction cup 11 is provided on the hanging basket body 10. The pneumatic suction cup 11 is used to extend and adsorb on the outer wall of the building or the glass to be broken when the hanging basket body 10 reaches the target floor. In this embodiment, the function of the pneumatic suction cup 11 is to be able to be automatically or manually controlled to extend and firmly adsorb on the outer wall surface of the building or the glass to be broken when the hanging basket body 10 reaches the target floor, so as to form a stable connection, effectively reduce the sway of the hanging basket in the air due to factors such as wind, and further reduce the reaction force during window breaking, enabling the robotic arm 211 to more easily control the window-breaking device 21, improving the window-breaking efficiency and shortening the rescue time.

[0040] In some embodiments, the distance between the boom 31 and the top of the building is greater than the sum of the minimum working length of the telescopic mechanism 40 and the height of the hanging basket body 10. In this way, in a non-fire situation, the rotation of the boom 31 is controlled by the rail moving mechanism 50, so as to retract the telescopic mechanism 40 together with the hanging basket body 10 and store them on the top of the building to hide the hanging basket body 10, thereby greatly reducing the risk of damage caused by falling objects and effectively avoiding the influence of strong wind on the hanging basket body 10.

[0041] The high-rise fire fighting hanging basket device provided by this embodiment realizes the stable and controllable lifting of the hanging basket body by setting a driving mechanism at the top of the building and adopting a telescopic mechanism combining a scissor-type guiding mechanism and a rigid chain, and also breaks through the limitations of traditional fire fighting equipment in terms of working height and space. The window-breaking device and fire extinguishing device equipped with this device can work together to quickly and accurately break the glass of the fire scene and spray the fire extinguishing agent in a timely manner, significantly improving the fire fighting and rescue efficiency. In addition, through the setting of pneumatic suction cups, the hanging basket body can be firmly adsorbed on the glass surface before breaking the window, effectively preventing shaking during the window-breaking process, and greatly ensuring the safety and reliability of the rescue operation.
