Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire fighting window breaking 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 fire-fighting window breaking device which breaks through the limitations of traditional fire-fighting equipment in terms of operating height and space and realizes the precise breaking of glass windows of high-rise buildings.

[0024] The following describes 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 illustrating and explaining the present invention, and are not used to limit the present invention.

[0025] As Figure 1As shown, the fire-fighting window breaking device described in this embodiment is used for high-rise building fire rescue, aiming to break through the limitations of traditional fire-fighting equipment in terms of operating height and space, and can quickly and safely perform window breaking operations in high-rise building fires, providing a channel for subsequent fire fighting and rescue. Figures 1 to 4 As shown, the window breaking device mainly includes a telescopic boom 10 , a driving assembly 20 and an impact head 30 .

[0026] The telescopic boom 10 can be telescopic in the vertical direction and is used to lift the window breaking device vertically from the top of the high-rise building to the target floor. Figure 1 , Figure 2 As shown, in this embodiment, the telescopic boom 10 includes a driving motor 11 and at least two sets of scissor-type guide mechanisms 12 extending vertically and arranged in parallel, and at least one rigid chain 13 is arranged between adjacent scissor-type guide mechanisms 12; the output end of the driving motor 11 is in transmission connection with the rigid chain 13, and is used to drive the hanging basket 40 to rise and fall by adjusting the extension length of the rigid chain 13. Specifically, in order to cover a wider range of rescue areas, a base 80 that can move along the edge of the roof is also provided on the roof of the high-rise building, and the driving motor 11 and the top of the scissor-type guide mechanism 12 are fixed on the base 80, and the control system of the base 80 can be linked with the fire control center of the building, and can automatically adjust the horizontal movement position and vertical lifting position of the telescopic boom 10 on the building according to the fire alarm information, so as to ensure that the window breaking device can be accurately lifted to the predetermined position of the target floor.

[0027] The window breaking device includes a driving assembly 20 and an impact head 30, wherein the driving assembly 20 is fixedly mounted at the end of the telescopic boom 10, and the impact head 30 is configured to be movable between a first position and a second position under the drive of the driving assembly 20, wherein the impact head 30 contacts the outer surface of the glass window of the target floor and smashes it during the movement from the first position to the second position. In this embodiment, the impact head 30 is preferably made of a high-hardness material such as tungsten steel, which has good wear resistance and impact toughness. The end of the impact head 30 can be designed to be a pointed cone, or designed to be other shapes according to actual needs to meet the window breaking needs of different types of glass windows.

[0028] When a fire occurs in a high-rise building, after the fire control center receives the fire alarm signal, the control base 80 drives the telescopic boom 10 to move to a predetermined position, and the telescopic boom 10 automatically extends to the target floor, so that the impact head 30 is aimed at the target window, and then the driving assembly 20 is started, and the impact head 30 moves between the first position and the second position, and the impact head 30 contacts the outer surface of the glass window of the target floor until it is broken, so as to provide a channel for subsequent fire fighting operations. The entire window breaking process is fast and efficient, which can buy precious time for fire rescue.

[0029] In some embodiments, the driving assembly 20 can adopt a swing driving mechanism, a launching driving mechanism or a linear driving mechanism. The core lies in ensuring that the impact head 30 can be recycled, thus effectively avoiding potential safety hazards caused by unexpected loss of the impact head 30. The specific structures and working principles of these three driving mechanisms will be elaborated in detail below.

[0030] First, for the swing driving mechanism, the driving assembly 20 mainly includes a driving motor and a swing arm. One end of the swing arm is firmly connected to the output shaft of the driving motor, and the other end is reliably connected to the impact head 30. In order to minimize the weight while ensuring sufficient strength, the swing arm is preferably made of high-strength aluminum alloy material. After receiving a control signal, the driving motor drives the swing arm to rotate around its output shaft, thereby driving the impact head 30 to reciprocate between a first position and a second position along a preset arc trajectory. To meet the requirements of different application scenarios, the swing angle range can be adjusted according to actual needs to ensure that the impact head 30 has sufficient operating stroke and generates sufficient impact force, so as to adapt to different types of window structures and glass materials.

[0031] Secondly, for the launching driving mechanism, the driving assembly 20 mainly includes a launcher and a winding and recycling device, and the impact head 30 is reliably connected to the winding and recycling device through a flexible cable. The main function of the launcher is to quickly launch the impact head 30 from the first position to the second position so that it can accurately impact the target glass. The launcher can be a pneumatic launcher, an electromagnetic launcher or a spring launcher, which is selected according to the actual application scenario. The winding and recycling device includes components such as a drum, a motor and a flexible cable, and these components need to be able to withstand the huge pulling force brought by the high-speed movement of the impact head 30. After the impact head 30 completes the window-breaking task, the winding and recycling device will quickly wind up the flexible cable, thereby reliably pulling the impact head 30 back to the first position for the next launch.

[0032] Furthermore, for the linear driving mechanism, the driving assembly 20 mainly includes a linear driver, and the output end of the linear driver is rigidly connected to the impact head 30. The linear driver is responsible for driving the impact head 30 to reciprocate between a first position and a second position along a linear trajectory, thereby achieving the purpose of breaking the window. The linear driver can be a cylinder, a hydraulic cylinder or a linear motor. In this embodiment, the linear driver is preferably a linear motor because the linear motor has the significant advantages of fast response speed and high control precision, and can better meet the requirements of quickly breaking the window.

[0033] In a specific implementation, such as Figure 4As shown, the driving component 20 adopts a manipulator structure. Different from the foregoing embodiments, the impact head 30 is installed at the end of the manipulator, and the robotic arm adopts a six-degree-of-freedom design, which means it has extremely high motion flexibility and operability. This design enables the manipulator to precisely control the position and posture of the impact head 30, thus being able to calmly handle various complex situations. For example, when the position of the building window is irregular, or there are obstacles such as protrusions on the building facade, the manipulator can avoid these obstacles by flexibly adjusting the posture of the impact head 30 to ensure the smooth completion of the window-breaking task.

[0034] In some embodiments, such as Figure 2 , Figure 4 As shown, a hanging basket 40 for carrying the driving component 20 is provided at the end of the telescopic jib 10. A high-pressure nozzle 50 is also provided inside the hanging basket 40. The high-pressure nozzle 50 is used to spray fire extinguishing agent into the building through the broken glass window by the impact head 30. To ensure the safety and reliability of the hanging basket 40, the hanging basket 40 is made of high-strength alloy material to ensure that it has sufficient load-bearing capacity to safely carry the driving component 20 and the high-pressure nozzle 50. In actual operation, when the impact head 30 successfully breaks the window glass, the high-pressure nozzle 50 inside the hanging basket 40 will be immediately activated and spray high-pressure water, dry powder and other fire extinguishing agents into the building, so as to synchronize the window-breaking and fire extinguishing. This efficient design can quickly control the spread of the fire, buy precious escape time for the trapped people, and greatly improve the rescue efficiency.

[0035] In some embodiments, such as Figure 2 As shown, the high-pressure nozzle 50 is connected to an external water source through a water supply pipe. A hose reel 60 is provided on the telescopic jib 10. The hose reel 60 is used to wind and unwind the water supply pipe according to the lifting and lowering movement of the hanging basket 40. Specifically, a water tank 61 communicated with the water supply pipe is installed on the base 80 to supply water to the high-pressure nozzle 50 continuously and stably. The hose reel 60 can automatically wind and unwind the water supply pipe according to the lifting and lowering movement of the hanging basket 40, always keeping the water supply pipe at an appropriate length and tension state, so as to ensure the smoothness of the water supply pipe and ensure the smooth progress of the fire extinguishing operation.

[0036] In some embodiments, such as Figure 4 As shown, it further includes: a vision sensor 70, arranged on the hanging basket 40, for collecting real-time images around the hanging basket 40 and identifying the position of the glass window; a controller, communicatively connected with the vision sensor 70, for controlling the actions of the telescopic jib 10, the driving component 20 and the high-pressure nozzle 50 according to the image information collected by the vision sensor 70.

[0037] In this way, through the vision sensor 70 and the controller, the operator can collect the images around the hanging basket 40 in real time to achieve precise positioning of the target window, ensuring that the impact head 30 can accurately align with the center position of the window, greatly improving the window-breaking efficiency and success rate. Moreover, the position and size of the fire source can be judged, and the spraying angle and flow rate of the high-pressure nozzle 50 can be automatically adjusted, thereby achieving precise fire extinguishing on the fire source, improving the fire-extinguishing efficiency, and reducing the waste of water resources.

[0038] The fire-fighting window-breaking device provided in this embodiment, by setting a hanging basket at the end of the telescopic boom and equipping it with a driving component and an impact head, not only breaks through the limitations of traditional fire-fighting equipment in terms of operating height and space, but also realizes precise breaking of the glass windows of high-rise buildings; by adopting various optional driving methods such as swinging, reciprocating, or launching, the impact head can flexibly respond according to different rescue scenarios, significantly improving the adaptability and reliability of the window-breaking operation; at the same time, the high-pressure nozzle equipped in the hanging basket can spray the fire extinguishing agent immediately after breaking the window, realizing the rapid connection between window-breaking and fire extinguishing, greatly shortening the rescue response time, and greatly improving the accuracy and efficiency of the rescue operation.
