Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) firefighting technology, specifically a hexacopter tethered UAV system for high-altitude firefighting. Background Technology

[0002] Firefighting drones are modern aerial equipment specifically designed for emergency rescue. They can replace personnel in high-risk fire scenes involving dense smoke, high temperatures, and explosions, offering high mobility, convenient takeoff and landing, and rapid response. Equipped with visible light and infrared thermal imaging gimbals, they can penetrate smoke and search for fire points and trapped personnel at night, transmitting real-time images to assist command and control in assessing the fire's trajectory. Heavy-duty models can carry fire extinguishing bombs and water tanks for high-altitude firefighting, and can also be equipped with loudspeakers and delivery devices for personnel evacuation and emergency supplies delivery. Widely used in high-rise building fire suppression, forest fire patrols, chemical storage tank monitoring, and post-disaster reconnaissance, they not only facilitate routine fire hazard inspections but also build air-ground coordinated rescue systems, significantly reducing the operational risks for firefighters and improving emergency response efficiency.

[0003] Currently, urban firefighting drones have been widely deployed and applied, offering significant advantages for firefighting operations in high-rise building corridors. This operational mode typically involves connecting a water hose to the drone's lower end, supplying water to the pipeline via a pump after takeoff, and then spraying water through side-mounted nozzles on the fuselage to extinguish the fire. However, in practical applications, especially in older residential buildings with small building spacing or where the building facade has various protruding components, the water hose and associated cables are prone to rubbing against protruding structures such as air conditioner units and security windows when the drone hovers. In extreme cases, the cables can even become entangled and jammed, not only interfering with the drone's stable flight but also directly hindering firefighting operations, severely limiting the reliability of this type of firefighting equipment in emergency situations. Therefore, to address these issues, a six-rotor tethered drone system for high-altitude firefighting is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a hexacopter tethered unmanned aerial vehicle system for high-altitude firefighting, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As an alternative solution to the hexacopter tethered drone system for high-altitude firefighting described in this invention, the hexacopter tethered drone system for high-altitude firefighting includes a drone fuselage, drone wings, fire hose connection module, and nozzle. Multiple drone wings are installed on the outside of the drone fuselage, and a fire hose connection module is fixedly connected to the bottom of the drone fuselage. A spray pipe is also installed on one side of the fire hose connection module. The fire hose connection module includes an installation frame, a water pipe, and a water pipe end connection mechanism. The top of the installation frame is fixedly connected to the drone body. The water pipe end connection mechanism is fixedly connected inside the installation frame. A spray pipe is fixedly connected to one side of the water pipe end connection mechanism. A water pipe is installed at the bottom of the water pipe end connection mechanism; The first telescopic device is also fixedly connected inside the mounting frame. The free end of the first telescopic device is fixedly connected to a self-detaching lifting device, and the other end of the self-detaching lifting device is equipped with a water pipe positioning mechanism. The water pipe positioning mechanism includes a second telescopic device, a limiting frame, and a limiting hole. The upper part of the second telescopic device is connected to a self-detaching hanger. The free end of the second telescopic device is fixedly connected to the limiting frame. A limiting hole is opened in the center of the limiting frame. A power-off button is also installed on the upper part of the limiting frame. An adsorption fixing component is also installed inside the limiting frame.

[0006] Currently, urban firefighting drones have been widely deployed and applied, offering significant advantages for firefighting operations in high-rise building corridors. This operational mode typically involves connecting a water hose to the bottom of the drone, supplying water to the pipeline via a pump after takeoff, and then spraying water through side-mounted nozzles on the fuselage to extinguish the fire. However, in practical applications, in older residential buildings with small building spacing, or in situations where the building facade has various protruding components, the water hose and associated cables are prone to rubbing against protruding structures such as air conditioner units and security windows when the drone hovers. In extreme cases, the pipes can even become entangled and jammed, not only interfering with the drone's stable flight but also directly hindering firefighting operations, severely limiting the reliability of this type of firefighting equipment in emergency situations. To address this, a recessed area at the bottom of the mounting frame accommodates a water pipe positioning mechanism, which is then housed within this recess. When operating in environments with protruding structural members on the building facade, the first telescopic mechanism is activated, extending the self-detaching lifting device and water pipe positioning mechanism downwards. Subsequently, the water pipe positioning mechanism actuates, anchoring on one side to the metal structural member of the building facade. After positioning, the self-detaching lifting device separates from the water pipe positioning mechanism, allowing the drone to take off normally and deliver water to the fire-prone area for firefighting. This water pipe positioning mechanism maintains a fixed distance between the water pipe and the wall, preventing the pipe from scraping against or entangled with protruding structures such as air conditioner units and security windows. It also suppresses disorderly swaying of the water pipe in windy conditions, reducing the impact of pipe swaying on the drone's flight attitude.

[0007] As an optional solution of the six-rotor tethered unmanned aerial vehicle system for high-altitude fire fighting described in this invention, the adsorption fixing component includes a buffer pad, an electromagnet and a sliding shaft. One end of the electromagnet is fixedly connected to the sliding shaft, the outer side of the sliding shaft is slidably connected to the inside of the limiting frame, and the other end of the sliding shaft is fixedly connected to a limiting ring. A buffer pad is fixedly connected to the other end of the electromagnet.

[0008] As an alternative solution to the six-rotor tethered unmanned aerial vehicle system for high-altitude firefighting described in this invention, a second spring is fixedly connected to the outer side of the sliding shaft. One end of the second spring is fixedly connected to the electromagnet, and the other end of the second spring is fixedly connected to the limiting frame.

[0009] As an optional solution to the six-rotor tethered unmanned aerial vehicle system for high-altitude firefighting described in this invention, a friction sleeve is also fixedly connected inside the limiting ring.

[0010] After the water pipe positioning mechanism completes its positioning, water is injected into the water pipe, causing it to expand. The built-in adsorption fixing component can hold the water pipe tightly, sharing the load of the water pipe's own weight on the drone's body and extending the drone's continuous operation time.

[0011] As an optional solution of the six-rotor tethered unmanned aerial vehicle system for high-altitude fire fighting described in this invention, the water pipe end connection mechanism includes a sealing frame, an automatic hose release device, and a connecting pipe. The outer side of the sealing frame is fixedly connected to the inside of the mounting frame. The automatic hose release device is fixedly connected to the bottom of the sealing frame. A water pipe is installed below the automatic hose release device. The connecting pipe is connected above the automatic hose release device. An expansion buffer pipe is connected above the connecting pipe. An elbow pipe is connected above the expansion buffer pipe. The other end of the elbow pipe is connected to a reducing pipe. The other end of the reducing pipe is connected to a spray pipe. A buffer is also fixedly connected above the elbow pipe.

[0012] As an optional embodiment of the six-rotor tethered unmanned aerial vehicle system for high-altitude firefighting described in this invention, the buffer component includes a buffer sleeve, a fixed plate, and a sliding rod. The bottom of the buffer sleeve is fixedly connected to the elbow pipe, the fixed plate is fixedly connected to the bottom of the buffer sleeve, the sliding rod is slidably connected inside the fixed plate, the bottom of the sliding rod is fixedly connected to a guide block, and the other end of the sliding rod is fixedly connected to a sealing plate. The outer side of the sealing plate is slidably connected to the inside of the buffer sleeve.

[0013] As an alternative solution to the hexacopter tethered unmanned aerial vehicle system for high-altitude firefighting described in this invention, the top of the buffer sleeve is provided with evenly distributed exhaust holes, and the lower side of the buffer sleeve is provided with air inlets.

[0014] As an alternative solution to the six-rotor tethered unmanned aerial vehicle system for high-altitude firefighting described in this invention, a first spring is also provided on the outer side of the sliding rod, one end of the first spring is fixedly connected to the sealing plate, and the other end of the first spring is fixedly connected to the fixing plate.

[0015] As an alternative solution to the six-rotor tethered unmanned aerial vehicle system for high-altitude firefighting described in this invention, the bottom of the guide block is arranged in an arc shape.

[0016] During water transport, pipe bends are susceptible to damage from water hammer impacts, which can also disrupt the flight attitude of drones. This solution adds an expansion buffer pipe at the outlet of the connecting pipe. When the high-pressure shock wave from the water hammer is transmitted to the bend, the expansion chamber space increases rapidly, enabling the fluid to expand and release pressure instantly, reducing the pressure on the bend. The buffer components inside the pipe can further buffer the water flow impact, weaken the effect of water hammer, and ensure the stable and reliable operation of the entire device.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The bottom of the mounting frame has a recessed groove for the water pipe positioning mechanism, which is housed within the groove. When operating in environments with protruding components on the exterior facade, the first telescopic mechanism is activated, extending the self-detaching lifting device and the water pipe positioning mechanism downwards. The water pipe positioning mechanism then actuates, anchoring on one side to the metal component of the building facade. After positioning, the self-detaching lifting device separates from the water pipe positioning mechanism, allowing the drone to take off normally and deliver water to the fire pipe for targeted firefighting. This water pipe positioning mechanism maintains a fixed distance between the water pipe and the wall, preventing the pipe from scraping against or entangled with protruding structures such as air conditioner units and security windows. It also suppresses disorderly swaying of the water pipe in windy conditions, reducing the impact of pipe swaying on the drone's flight attitude.

[0018] After the water pipe positioning mechanism completes its positioning, water is injected into the water pipe, causing it to expand. The built-in suction clamping component can then hold the water pipe tightly, sharing the load of the water pipe's own weight on the drone's body and extending the drone's continuous operating time.

[0019] During water transport, pipe bends are susceptible to damage from water hammer impacts, which can also disrupt the flight attitude of drones. This solution adds an expansion buffer pipe at the outlet of the connecting pipe. When the high-pressure shock wave from the water hammer is transmitted to the bend, the expansion chamber space increases rapidly, enabling the fluid to expand and release pressure instantly, reducing the pressure on the bend. The buffer components inside the pipe can further buffer the water flow impact, weaken the effect of water hammer, and ensure the stable and reliable operation of the entire device.

Detailed Implementation

[0022] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a technical solution: A six-rotor tethered unmanned aerial vehicle (UAV) system for high-altitude fire fighting includes a UAV fuselage 1, UAV wings 2, a fire hose connection module 3, and a nozzle 4. Multiple drone wings 2 are installed on the outside of the drone fuselage 1. A fire water pipe connection module 3 is fixedly connected to the bottom of the drone fuselage 1. A spray pipe 4 is also installed on one side of the fire water pipe connection module 3. Among them, the fire water pipe connection module 3 includes a mounting frame 301, a water pipe 302 and a water pipe end connection mechanism 303. The top of the mounting frame 301 is fixedly connected to the drone body 1. The water pipe end connection mechanism 303 is fixedly connected inside the mounting frame 301. A spray pipe 4 is fixedly connected to one side of the water pipe end connection mechanism 303. A water pipe 302 is installed at the bottom of the water pipe end connection mechanism 303; The first telescopic device 304 is also fixedly connected inside the mounting frame 301. The free end of the first telescopic device 304 is fixedly connected to a self-detaching lifting device 306. The other end of the self-detaching lifting device 306 is equipped with a water pipe positioning mechanism 305. The water pipe positioning mechanism 305 includes a second telescopic device 3051, a limiting frame 3052, and a limiting hole 3053. The upper part of the second telescopic device 3051 is connected to the self-detaching hanger 306. The free end of the second telescopic device 3051 is fixedly connected to the limiting frame 3052. The limiting frame 3052 has a limiting hole 3053 in the center. A power off button 3060 is also installed on the upper part of the limiting frame 3052. An adsorption fixing component is also installed inside the limiting frame 3052.

[0023] Currently, urban firefighting drones have been widely deployed and applied. For fires in high-rise building corridors, using drones for firefighting operations offers significant advantages. This operational mode typically involves connecting a water hose to the bottom of the drone, supplying water to the pipeline via a pump after takeoff, and then spraying water through side-mounted nozzles on the fuselage to extinguish the fire. However, in practical applications, in older residential buildings with small building spacing, or in situations where the building facade has various protruding components, the water hose and associated cables below the drone are prone to rubbing against protruding structures such as air conditioner units and security windows when hovering. In extreme cases, the pipes may even become entangled and jammed, not only interfering with the drone's stable flight but also directly hindering firefighting operations, severely limiting the reliability of this type of firefighting equipment in emergency use. To address this, the mounting frame 301 has a recessed groove at its bottom to accommodate a water pipe positioning mechanism 305, which is housed within the groove. When working in environments with protruding components on the building facade, the first telescopic mechanism 304 is activated, extending the self-detaching lifting device 306 and the water pipe positioning mechanism 305 downwards. Subsequently, the water pipe positioning mechanism 305 actuates, anchoring on one side to the metal components of the building facade. After positioning, the self-detaching lifting device 306 separates from the water pipe positioning mechanism 305, allowing the drone fuselage 1 to take off normally and deliver water to the water pipe 302 to extinguish the fire. The water pipe positioning mechanism 305 maintains a fixed distance between the water pipe 302 and the wall, preventing the water pipe 302 from scraping against or entangled with protruding structures such as air conditioner units and security windows. It also suppresses disorderly swaying of the water pipe in windy conditions, reducing the impact of the water pipe 302's swaying on the drone fuselage 1's flight attitude.

[0024] Also includes the following: For operations involving protruding components on the facade, the second telescopic mechanism 3051 drives the other limiting frame 3052 to move towards the protruding metal component that can be magnetically attracted by the electromagnet, causing the adsorption fixing component to adhere to the protruding metal component and complete magnetic positioning. During this stage, the water pipe 302 is not filled with water and is in a flattened shape, stored in the limiting hole 3053, allowing the drone to smoothly carry the water pipe 302 for relocation. After the drone climbs to the designated operating height, water is introduced into the water pipe 302. The water pressure causes the water pipe 302 to expand, and the expanded water pipe 302 cooperates with the adsorption fixing component to achieve self-locking and fixation, allowing firefighting operations to commence. After the firefighting operation is completed, the water pipe 302 automatically separates from the upper water pipe end docking mechanism 303. The operator can then reach the position of the adsorption fixing component and press the power-off button 3060 to easily release the magnetic attraction and remove the entire positioning component. If there are no protruding components on the facade, the water pipe positioning mechanism 305 will not be operational.

[0025] Example 2: This example is an improvement on Example 1. Please refer to Example 1. Figure 6 and Figure 7 Specifically, the adsorption fixing component includes a buffer pad 3054, an electromagnet 3055, and a sliding shaft 3056. One end of the electromagnet 3055 is fixedly connected to the sliding shaft 3056. The outer side of the sliding shaft 3056 is slidably connected to the inside of the limiting frame 3052. The other end of the sliding shaft 3056 is fixedly connected to a limiting ring 3057. The other end of the electromagnet 3055 is fixedly connected to a buffer pad 3054.

[0026] A second spring 3059 is also fixedly connected to the outside of the sliding shaft 3056. One end of the second spring 3059 is fixedly connected to the electromagnet 3055, and the other end of the second spring 3059 is fixedly connected to the limit frame 3052.

[0027] The limiting ring 3057 is also fixedly connected to a friction sleeve 3058.

[0028] After the water pipe positioning mechanism 305 completes the positioning, water is injected into the water pipe 302, causing the water pipe 302 to expand. The built-in adsorption fixing component can hold the water pipe 302 tightly, sharing the load of the water pipe's own weight on the drone body 1 and extending the drone's continuous operation time.

[0029] Also includes the following: After the limiting bracket 3052 drives the adsorption fixing component to move laterally to the preset position, the electromagnet 3055 is energized and adsorbs and fixes itself to the magnetically adsorbable metal structure. The end face of the electromagnet 3055 is equipped with a buffer pad 3054, which can ensure a firm adsorption even if the metal contact surface is uneven. When the electromagnet 3055 moves, it synchronously drives the sliding shaft 3056 and the end limiting ring 3057 to move together. The limiting ring 3057 slides inside the limiting hole 3053 to form a misaligned posture, which is used to tighten the expanded water pipe 302. The limiting ring 3057 has a built-in friction sleeve 3058, which can fit tightly with the outer wall of the water pipe 302 to achieve locking and positioning, and can withstand the downward pulling load of the water pipe 302, reducing the load on the drone.

[0030] During the power outage recovery phase, the second spring 3059 drives the electromagnet 3055 to reverse and retract into the limit frame 3052, making it easy for the device to be reused.

[0031] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 4 and Figure 5 Specifically, the water pipe end connection mechanism 303 includes a sealing frame 3031, an automatic hose disconnector 3032, and a connecting pipe 3033. The outer side of the sealing frame 3031 is fixedly connected to the inside of the mounting frame 301. The automatic hose disconnector 3032 is fixedly connected to the bottom of the sealing frame 3031. A water pipe 302 is installed below the automatic hose disconnector 3032. The connecting pipe 3033 is connected above the automatic hose disconnector 3032. An expansion buffer pipe 3034 is connected above the expansion buffer pipe 3034. An elbow pipe 3035 is connected above the expansion buffer pipe 3034. The other end of the elbow pipe 3035 is connected to a reducing pipe 3037. The other end of the reducing pipe 3037 is connected to a spray pipe 4. A buffer component 3036 is also fixedly connected above the elbow pipe 3035.

[0032] The buffer component 3036 includes a buffer sleeve 361, a fixed plate 362, and a sliding rod 363. The bottom of the buffer sleeve 361 is fixedly connected to the elbow pipe 3035. The fixed plate 362 is fixedly connected to the bottom of the buffer sleeve 361. The sliding rod 363 is slidably connected inside the fixed plate 362. The bottom of the sliding rod 363 is fixedly connected to a guide block 364. The other end of the sliding rod 363 is fixedly connected to a sealing plate 365. The outer side of the sealing plate 365 is slidably connected to the inside of the buffer sleeve 361.

[0033] The top of the buffer sleeve 361 is provided with evenly distributed exhaust holes 368, and the lower side of the buffer sleeve 361 is provided with air inlet holes 367.

[0034] A first spring 366 is also provided on the outside of the sliding rod 363. One end of the first spring 366 is fixedly connected to the sealing plate 365, and the other end of the first spring 366 is fixedly connected to the fixed plate 362.

[0035] The bottom of the flow guide block 364 is curved.

[0036] During water transport, pipe bends are susceptible to damage from water hammer impacts, which can also disrupt the flight attitude of drones. This solution adds an expansion buffer pipe 3034 to the outlet end of the connecting pipe 3033. When the high-pressure water hammer shock wave is transmitted to the bend, the expansion chamber space increases sharply, achieving instantaneous fluid expansion and pressure relief, reducing the pressure on the bend. The internal buffer component 3036 can further buffer the water flow impact, weaken the water hammer effect, and ensure the stable and reliable operation of the entire device.

[0037] Also includes the following: During water injection, water flows through the connecting pipe 3033 into the expansion buffer pipe 3034, utilizing the expansion space to achieve instantaneous expansion and pressure relief of the water, reducing the impact of the water flow on the bend of the elbow pipe 3035. An internal buffer component 3036 is installed in the pipeline, and the water flow achieves unilateral diversion and guidance after impacting the guide block 364. The impact force of the water flow pushes the guide block 364 to move the linkage sliding rod 363, thereby causing the sealing plate 365 to slide inside the buffer sleeve. Because the top vent hole 368 has a small diameter, it can suppress the instantaneous and rapid discharge of gas, further enhancing the water pressure buffering effect. The reducer pipe 3037 at the rear end can further pressurize the water flow, ensuring the water jet range and meeting the fire extinguishing spray distance requirements.

[0038] After the fire extinguishing operation is completed, the first spring 366 drives the sealing plate to reset, so that the guide block 364 returns to the side of the vertical section of the elbow pipe 3035, ensuring that the mechanism can operate repeatedly.
