[0002] Fires in high-rise buildings are characterized by their high floors, large building volumes, concentrated populations, and difficult evacuation and rescue efforts. Once a fire breaks out, it can cause significant economic losses and casualties. Firefighting methods in high-rise buildings primarily rely on internal firefighting devices, such as fire hydrants and automatic sprinkler systems. This method of firefighting can only extinguish fires within the building. However, when a fire spreads to the exterior of the building, flames and smoke escape through windows. Internal firefighting devices are often unable to contain the fire immediately, potentially affecting upper floors. Therefore, further improvements to current firefighting devices are necessary.

[0003] The prior art with announcement number CN114053623A discloses an automatic sprinkler fire extinguishing system for the exterior wall of a building, including a high-level fire water tank, which is arranged on the roof of the building for storing water; a plurality of sprinkler devices, which are used to spray the fire floor; a water pipe, which connects the high-level fire water tank and the sprinkler device to divert the water in the high-level fire water tank to the sprinkler device; a plurality of detection devices, which are used to detect the status of the building wall in real time and output corresponding detection signals; a main control module, which is connected to the plurality of detection devices and the plurality of sprinkler devices, and is used to receive the detection signals of the plurality of detection devices, judge the fire status of the building wall according to the detection signals, and control the sprinkler device at the corresponding position to open when it is determined that there is a fire point in the building wall; wherein, each floor is provided with at least one sprinkler device and at least one detection device.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problems in the prior art that the automatic sprinkler fire extinguishing system on the exterior wall of a building needs to be equipped with a sprinkler device on each floor of the building in order to fire the entire building, the installation of the sprinkler device is cumbersome, and the fire fighting cost is high, the present invention provides a building facade sprinkler fire extinguishing device, which can use a water gun to spray water for fire fighting on any floor of the building, without the need to install a sprinkler device on each floor, eliminating the cumbersome installation and reducing the fire fighting cost.

[0020] It should be noted that the building facade water sprinkler fire extinguishing device described in the present invention is used for but not limited to residential building fire protection, etc. For the convenience of explanation, in the present invention, only the application of the building facade water sprinkler fire extinguishing device to residential building fire protection is used as an example for explanation, and the principles of the building facade water sprinkler fire extinguishing device applied to other types of equipment are essentially the same as those applied to residential building fire protection, and will not be repeated here.

[0021] See also Figure 1 , Figure 1 This is a structural schematic diagram of a water sprinkler fire extinguishing device for a building facade in one embodiment of the present invention. The water sprinkler fire extinguishing device for a building facade includes a lifting assembly 1 and a fire-fighting robot 2. The lifting assembly 1 includes a frame 11 and a lifting platform 12 that are slidably connected; the fire-fighting robot 2 includes a base 21 and a water gun 22. The base 21 is slidably arranged on the lifting platform 12, and the sliding direction of the base 21 is perpendicular to the lifting direction (sliding direction) of the lifting platform 12. The water gun 22 is arranged on the base 21 and is used for spraying water.

[0022] In this embodiment, the frame 11 can be used to be installed on the facade of the building 3 and is arranged vertically downward so that the lifting platform 12 is slidably connected to the frame 11 and can slide back and forth and rise and fall along the height direction of the building. The fire-fighting robot 2 is located on the lifting platform 12 and can adjust its height as the lifting platform 12 rises and falls to reach the corresponding floor to be responded to by the fire. The lifting range of the lifting platform 12 covers all floors, so the fire-fighting robot 2 can extinguish fires on any floor of the building 3 as the lifting platform 12 rises and falls, without the need to install sprinkler fire-fighting devices on each floor, thus saving costs. In addition, the water gun 22 of the fire-fighting robot 2 can slide along the lifting platform 12 through the base 21 to spray water at multiple locations on the current floor to increase the fire-fighting area.

[0023] In one embodiment, see Figure 2The frame 11 includes a plurality of parallel vertical rails 111 and a connecting ring 112 arranged in a circle at intervals. The vertical rails 111 are arranged along the height direction of the building 3. The connecting ring 112 connects the plurality of vertical rails 111 at the same time, and the lifting platform 12 slides and connects the plurality of vertical rails 111 at the same time. In this embodiment, the plurality of vertical rails 111 are arranged around the facade of the building 3 and can be compatible with the installation of facades of different shapes, such as rectangular facades, circular facades or polygonal facades. All the vertical rails 111 are arranged in parallel, and the lifting platform 12 slides and connects all the vertical rails 111 at the same time, so that the lifting platform 12 can slide up and down stably and smoothly to achieve lifting. The top of the vertical rail 111 roughly extends to the rooftop of the building. The connecting ring 112 is located on the rooftop and connected to all the vertical rails 111 so that all the vertical rails 111 are connected to form a whole, which is conducive to improving the stability of the entire lifting assembly 1. The connecting ring 112 is installed and connected to the vertical rails 111 on the rooftop, which is convenient for construction. The connecting ring 112 can be tied to the vertical rail 111 by a steel wire, or can be detachably connected to the vertical rail 111 by screws.

[0024] In one embodiment, see Figure 1 and Figure 3 The vertical rail 111 is provided with a plurality of positioning holes 113 arranged at intervals along its length, and the lifting platform 12 can be detachably engaged with any of the positioning holes 113. In this embodiment, the specific positions of the plurality of positioning holes 113 can correspond to the floors of the building. For example, if the spacing between floors is three meters, then the spacing between two adjacent positioning holes 113 is also three meters. This allows the lifting platform 12 to stay exactly on that floor when engaged with the positioning holes 13, so that the firefighting robot 2 on the lifting platform 12 can move along the lifting platform 12 and accurately extinguish the fire on that floor.

[0025] In one embodiment, see Figure 3The lifting assembly 1 includes a first clip 14 and a second clip 15 rotatably mounted on the lifting platform 12. The vertical rail 111 has a positioning block 16, which defines the aforementioned positioning hole 113. The first clip 14 can abut the positioning block 16 when rotating, allowing the second clip 15 to rotate and engage the positioning hole 113. The first clip 14 and the second clip 15 of this embodiment are controlled to rotate or reset by corresponding first and second servos 141 and 151, respectively. The servos are mounted on the lifting platform 12 and connected to the corresponding clips. When the lifting platform 12 is about to reach the target floor during the lifting process, the first servo 141 can be controlled to rotate and extend the first clip 14 until the first clip 14 abuts the positioning block 16, indicating that the lifting platform 12 has reached the target floor. At this time, the second servo 151 can be controlled to rotate and extend the second clip 15 to engage the positioning hole 113, completing the locking of the lifting platform 12 and ensuring that the lifting platform 12 remains stably on the target floor. When the lifting platform 12 needs to move to another floor, it only needs to control the first servo 141 and the second servo 151 to drive the first clamping member 14 and the second clamping member 15 to rotate and reset. It should be emphasized that it is not necessary to set the positioning blocks 16 on all vertical rails 111. The positioning blocks 16 can be installed on a few vertical rails 111 that are farther away, preferably near the corners of the building. The installation position of the servo corresponds to the position of the vertical rails 111 with the positioning blocks 16.

[0026] In one embodiment, see Figure 4 The lifting assembly 1 also includes a lifting and pulling mechanism 17, which includes a pull rope 171, a winding wheel 172, and a lifting motor 173. The pull rope 171 is wound around the winding wheel 172, one end of the pull rope 171 is connected to the lifting platform 12, and the lifting motor 173 is connected to the winding wheel 172 and is used to drive the winding wheel 172 to rotate to drive the lifting platform 12 to move up and down. In this embodiment, the lifting and pulling mechanism 17 can be installed on the rooftop of the building, and the winding wheel 172 is rotated on the rooftop. When working, the lifting motor 173 can drive the winding wheel 172 to rotate, so that the winding wheel 172 releases or retracts the pull rope 171, and the lifting platform 12 is moved up and down through the pull rope 171. The number of lifting and pulling mechanisms 17 can be set according to actual needs. Usually, four are set, respectively, and are respectively set at the four corners of the building. The four pull ropes 171 are respectively connected to the four top corners of the lifting platform 12. In addition, the rooftop can be provided with some backup batteries for supplying power to the lifting and pulling mechanism 17 to prevent the lifting and pulling mechanism 17 from malfunctioning in the event of a power outage due to a fire.

[0027] In one embodiment, see Figure 5The lifting assembly 1 further includes a fixed rack 18 mounted on the lifting platform 12. The firefighting robot 2 further includes a drive motor 23 and a gear 24 mounted on the base 21. The gear 24 engages the fixed rack 18. The drive motor 23 is connected to the gear 24 and is capable of driving the gear 24 to rotate, thereby causing the gear 24 to slide the base 21 through the reaction force of the engagement. In this embodiment, the drive motor 23 is capable of driving the gear 24 to rotate during operation, while the fixed rack 18 is stationary. The gear 24, through the reaction force of the engagement with the fixed rack 18, drives the base 21 to slide along the lifting platform 12 to adjust the position of the water gun 22.

[0028] The lifting platform 12 is provided with a slide rail 121 and a slider 122 along its extension direction. In addition, a receiving groove is provided in the middle portion of the lifting platform 12. The receiving groove is used to accommodate the fixed rack 18 and the drive motor 23. There are two slide rails 121, which are arranged at the top of the lifting platform 12 and located on both sides of the receiving groove. The slider 122 is slidably arranged on the slide rails 121. The slider 122 can be connected to the base 21 of the firefighting robot 2 by screws. The base 21 is also connected to the top of the drive motor 23 by screws. When the drive motor 23 is in operation, it drives the gear 24 to rotate. The reaction force of the engagement between the gear 23 and the fixed rack 18 drives the firefighting robot 2 to slide along the slide rail 121 through the slider 122.

[0029] In one embodiment, see Figure 2 The firefighting robot 2 further includes a battery 25 and a solar panel 26 disposed on the base 21. The solar panel 26 is connected to the battery 25, which is in turn connected to the drive motor 23 and the water gun 22. In this embodiment, the solar panel 26 can be used to charge the battery 25 using solar energy. The battery 25 can store a large amount of electrical energy to prevent power outages in the event of a fire, which could result in the firefighting robot 2 being unable to operate normally due to a power outage.

[0030] In one embodiment, the lifting assembly 1 further includes a water supply hose mounted on the lifting platform 12. One end of the water supply hose is connected to a water gun 22, and the other end is detachably connected to a fire hydrant located on each floor of the building. The water supply hose of this embodiment is connected to a fire hydrant located on the corresponding floor, obtaining water from the fire hydrant. The water collected by the water supply hose is then fed into the water gun 22, which then sprays water at the fire site. As the firefighting robot 2 moves along the lifting platform 12, the water supply hose can move with the firefighting robot 2, ensuring that the firefighting robot 2 maintains a constant water supply and can spray water while moving.

[0031] The shape of the lifting platform 12 is not limited, and can be, for example, L-shaped, C-shaped, or annular. In a preferred embodiment, the lifting platform 12 is a closed ring, so that the firefighting robot 2 can slide along the circumference of the lifting platform 12. In this embodiment, the lifting platform 12 is configured as a ring, so that the firefighting robot 2 can move around the building and move to any position on the floor of the building, thereby extinguishing fires in all blind spots on the floor and increasing the firefighting area.

[0032] In one embodiment, see Figure 2 The building facade sprinkler fire extinguishing device also includes a visual control component 3, which is provided on the fire-fighting robot 2 and is used to provide intelligent guidance for the water spraying of the fire-fighting robot 2. The visual control component 3 includes a main controller 31 and a camera 32 and a steering gear 33 connected to the main controller 31. The steering gear 33 is connected to the water gun 22 and is used to drive the water gun 22 to rotate. The camera 32 is provided on the base 21. The main controller 31 can automatically control the steering gear 33 to drive the water gun 22 to rotate according to the fire picture taken by the camera 32. In this embodiment, the steering gear 33 is rotatably provided on the base 21 and connected to the water gun 22. In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the present invention is described in detail: The building facade sprinkler fire extinguishing device provided by the present invention comprises a frame 11 that can be installed on the facade wall of a building 3 and arranged along the height direction of the facade wall. A lifting platform 12 is slidably connected to the frame 11 and can be raised and lowered along the height direction of the facade of the building 3 during sliding, so that the water gun on the lifting platform 12 can reach the fire floor. The water gun 22 can slide along the lifting platform 12 via the base to accurately reach the specific fire location on the fire floor and accurately extinguish the fire at the fire location. Compared with the existing technology, the present invention does not require the installation of a sprinkler device on each floor. Only a single water gun is used to reach any floor and extinguish fires on all floors, thereby reducing firefighting costs.
