DETAILED DESCRIPTION

[0024] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0025] As Figure 1As shown, the fire window breaking device described in the embodiment is used for fire rescue in high-rise buildings, aiming to break through the limitations of traditional fire equipment in operation height and space, and can quickly and safely perform window breaking operation in high-rise building fire to provide a passage for subsequent fire extinguishing 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 for vertically lifting the window breaking device from the top of the high-rise building to the target floor. In order to realize stable and reliable lifting, as shown in Figure 1 , Figure 2 In the embodiment, the telescopic boom 10 includes a driving motor 11 and at least two groups of scissor-type guide mechanisms 12 vertically extending 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 for driving the lifting basket 40 to lift by adjusting the extension length of the rigid chain 13. Specifically, in order to cover a larger rescue area, the top of the high-rise building is also provided with a base 80 which can move along the edge of the top, 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, so as to automatically adjust the horizontal moving position and the vertical lifting position of the telescopic boom 10 on the building according to the fire alarm information, and ensure that the window breaking device can be accurately lifted to the predetermined position of the target floor.

[0027] The window breaking device includes the driving assembly 20 and the impact head 30, the driving assembly 20 is fixedly installed at the end of the telescopic boom 10, and the impact head 30 is configured to move between the first position and the second position under the driving of the driving assembly 20, wherein the impact head 30 contacts and breaks the outer surface of the glass window of the target floor in the process of moving from the first position to the second position. In the embodiment, the impact head 30 is preferably made of 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 as a sharp cone, or designed into other shapes according to actual needs, so as to meet the window breaking needs of different types of glass windows.

[0028] When the high-rise building catches fire, after the fire control center receives the fire alarm signal, the base 80 drives the telescopic boom 10 to move to the predetermined position, the telescopic boom 10 automatically extends to the target floor, the impact head 30 is aligned with the target window, then the driving assembly 20 is started, the impact head 30 moves between the first position and the second position, the impact head 30 contacts and breaks the outer surface of the glass window of the target floor until the passage is provided for subsequent fire extinguishing operation. The whole window breaking process is fast and efficient, which can save valuable 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 of which is to ensure that the impact head 30 can be recycled, thereby effectively avoiding the safety hazards that may be caused by the unexpected loss of the impact head 30. The specific structure and working principle of the three driving mechanisms will be described in detail below.

[0030] Firstly, 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 with the output shaft of the driving motor, and the other end is reliably connected with the impact head 30. In order to reduce the weight as much as possible under the premise of ensuring sufficient strength, the swing arm is preferably made of high-strength aluminum alloy material. After receiving the control signal, the driving motor drives the swing arm to rotate around its output shaft, thereby driving the impact head 30 to reciprocate along the preset circular arc trajectory between the first position and the second position. In order to meet the needs of different application scenarios, the swing angle range can be adjusted according to actual needs to ensure that the impact head 30 has sufficient running 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 with 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 hit 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 a winding drum, a motor and a flexible cable, etc., which need to be able to withstand the huge tension caused 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 the flexible cable, thereby reliably pulling the impact head 30 back to the first position for the next launch.

[0032] Thirdly, 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 with the impact head 30. The linear driver is responsible for driving the impact head 30 to reciprocate along a straight line between the first position and the second position, thereby achieving the purpose of breaking the window. The linear driver can be a pneumatic 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, which can better meet the needs of fast window breaking.

[0033] In a specific implementation, as shown in FIG. 6, the driving assembly 20 is arranged on the side of the window breaking device 10 that is far away from the window to be broken, and the impact head 30 is arranged on the side of the window breaking device 10 that is close to the window to be broken. In this way, the impact head 30 can be launched from the first position to the second position along the straight line trajectory, and then the impact head 30 can hit the target glass along the straight line trajectory. Figure 4As shown, the driving assembly 20 adopts a mechanical arm structure, and unlike the previous embodiments, the impact head 30 is installed at the end of the mechanical arm, and the mechanical arm adopts a six-degree-of-freedom design, which means that it has extremely high movement flexibility and operability. This design enables the mechanical arm to accurately control the position and posture of the impact head 30, so as to calmly cope with various complex situations. For example, when the building window position is irregular, or there are obstacles such as protrusions on the building facade, the mechanical arm can avoid these obstacles by flexibly adjusting the posture of the impact head 30, ensuring the smooth completion of the window breaking task.

[0034] In some embodiments, as shown in Figure 2 , Figure 4 As shown, the end of the telescopic boom 10 is provided with a basket 40 for carrying the driving assembly 20, and the basket 40 is also provided with a high-pressure spray head 50 inside, which is used to spray fire extinguishing agent into the building interior through the glass window broken by the impact head 30. In order to ensure the safety and reliability of the basket 40, the basket 40 is made of high-strength alloy material to ensure that it has sufficient carrying capacity and can safely carry the driving assembly 20 and the high-pressure spray head 50. In actual operation, when the impact head 30 successfully breaks the window glass, the high-pressure spray head 50 located inside the basket 40 will immediately start and spray high-pressure water, dry powder and other fire extinguishing agents into the building interior, thereby realizing the synchronous performance of breaking the window and extinguishing the fire. This efficient design can quickly control the spread of the fire and gain valuable escape time for trapped personnel, greatly improving the efficiency of rescue.

[0035] In some embodiments, as shown in Figure 2 The high-pressure spray head 50 is connected to an external water source through a water supply pipe, and the telescopic boom 10 is provided with a pipe winder 60 for winding and unwinding the water supply pipe according to the lifting movement of the basket 40. In specific implementation, a water tank 61 in communication with the water supply pipe is installed on the base 80 to continuously and stably supply water to the high-pressure spray head 50, and the pipe winder 60 can automatically wind and unwind the water supply pipe according to the lifting movement of the basket 40, always keeping the water supply pipe in a suitable length and tension state, thereby ensuring the smoothness of the water supply pipe and the smooth progress of the fire extinguishing operation.

[0036] In some embodiments, as shown in Figure 4 It also includes a visual sensor 70 arranged on the basket 40 for collecting real-time images around the basket 40 and identifying the position of the glass window; a controller in communication with the visual sensor 70 for controlling the actions of the telescopic boom 10, the driving assembly 20 and the high-pressure spray head 50 according to the image information collected by the visual sensor 70.

[0037] In this way, through the visual sensor 70 and the controller, the operator can collect images around the basket 40 in real time to realize accurate positioning of the target window, ensure that the impact head 30 can accurately aim at the center position of the window, greatly improve the window breaking efficiency and success rate, and can judge the position and size of the fire source, and automatically adjust the spray angle and flow of the high-pressure spray head 50, so as to realize accurate fire extinguishing of the fire source, improve the fire extinguishing efficiency, and reduce the waste of water resources.

[0038] The fire-fighting window breaking device provided by the embodiment breaks through the limitations of traditional fire-fighting equipment in operation height and space, realizes accurate breaking of glass windows of high-rise buildings, and can make the impact head flexibly cope with different rescue scenes through various optional driving modes such as swing type, reciprocating type or launching type, thereby significantly improving the adaptability and reliability of window breaking operation.
