Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a UAV used for firefighting in high-rise buildings. Background Technology

[0002] With rapid economic development and continuous social progress, the number of high-rise buildings in cities has increased significantly. Traditional fire-fighting equipment faces challenges such as being unable to reach, enter, or deploy slowly in the face of fires in high-rise buildings. Therefore, it is necessary to use drones for firefighting.

[0003] Currently, most fire-fighting drones on the market extinguish fires by launching fire-extinguishing missiles or dropping fire-extinguishing bombs. For example, patent application CN201810928941.X proposes a control system and fire-fighting system for rotorcraft drones used for fire suppression in high-rise buildings. This application uses a rotorcraft drone equipped with a high-altitude detection module, controller, and ignition relay to control the precise launch of fire-extinguishing bombs towards the fire. However, this method requires frequent replenishment of fire-extinguishing materials, thus it cannot meet the needs of large-area fire suppression. A small number of drones on the market use water-soluble fire-extinguishing materials for fire suppression. For example, patent application CN202211207181.6 proposes a fire-fighting system and method for high-rise buildings. This application connects a fire hose to a foam delivery system to continuously deliver fire-extinguishing materials to the drone. However, when the building is too high, it requires very strong pressure to deliver water to the high place, and the nozzle structure is a fixed structure, so the drone can only be moved up and down manually to achieve accurate fire suppression.

[0004] Therefore, there is an urgent need for a fire-fighting drone that can flexibly adjust the spray direction of the extinguishing agent and has a combined fire-fighting capability. Utility Model Content

[0005] Based on the above-mentioned technical problems, the purpose of this utility model is to provide a drone for extinguishing fires in high-rise buildings, which can adjust the spray direction of the fire extinguishing components from multiple angles and can freely switch between dry powder fire extinguishing agents or water-based fire extinguishing agents according to the actual situation, thereby improving the fire extinguishing efficiency.

[0006] The specific technical solution is as follows: A high-rise building firefighting drone includes: a drone body, a yaw axis motor, a two-axis gimbal, a pitch axis motor, a crank, a connecting rod, and a firefighting assembly. The yaw axis motor is fixed to the bottom of the drone body, and its output end is connected to the two-axis gimbal via a connector. The two-axis gimbal includes a gimbal base plate, a gimbal side plate, and a connecting plate. The connecting plate is fixed to the gimbal base plate and hinged to the gimbal side plate, and the top of the gimbal side plate is connected to the connector. The two ends of the connecting rod are rotatably connected to the gimbal side plate and the crank, respectively. The crank is located outside the output end of the pitch axis motor, and the pitch axis motor is fixed to the connecting plate. The firefighting assembly includes a dry powder fire extinguishing canister, a dry powder nozzle, and a water-based fire extinguishing nozzle. The dry powder fire extinguishing canister is located on the top of the drone body, and the dry powder nozzle and the water-based fire extinguishing nozzle are respectively located on the gimbal base plate and are respectively connected to the dry powder fire extinguishing canister and the fire hose.

[0007] In addition, the drone for firefighting in high-rise buildings provided by the present invention may also have the following additional technical features: The above technical solution also includes: a flow rate control valve, which is installed on the dry powder spray pipe.

[0008] In the above technical solution, an industrial camera and an image transmission module are respectively installed on the gimbal base plate.

[0009] In the above technical solution, the dry powder nozzle is located above the pan-tilt base plate, the water-based fire extinguishing nozzle is located below the pan-tilt base plate, and the industrial camera is located between the dry powder nozzle and the water-based fire extinguishing nozzle.

[0010] In the above technical solution, the dry powder nozzle and the water-based fire extinguishing nozzle are fixed to the top and bottom surfaces of the gimbal base plate by detachable clamps, respectively.

[0011] The advantages of this utility model for firefighting in high-rise buildings compared with existing technologies are as follows: 1. Powered by the yaw axis motor and pitch axis motor, and driven by the combined use of crank and connecting rod, the two-axis gimbal moves, allowing the fire extinguishing components to be adjusted at multiple angles in the pitch and yaw axis directions. This expands the range of the spray fire extinguishing, enabling flexible adaptation to the fire source locations of high-rise concrete facades, windows, or complex spaces, thereby improving fire extinguishing efficiency.

[0012] 2. By setting up dry powder fire extinguishing tanks, dry powder nozzles, and water-based fire extinguishing nozzles, the system can freely switch between dry powder and water-based fire extinguishing agents according to the actual situation on site.

[0013] 3. By equipping drones with fire extinguishing components, two-axis gimbals, and other parts, they can quickly reach the scene in the early stages of a fire and extinguish it using a combination of dry powder and water-based fire extinguishing agents, thereby shortening the firefighting time.

Detailed Implementation

[0015] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0016] A type of drone for firefighting in high-rise buildings, such as Figure 1-5 As shown, the system includes: a drone body 10, a yaw axis motor 11, a two-axis gimbal 12, a pitch axis motor 13, a crank 14, a connecting rod 15, and a fire extinguishing assembly. The yaw axis motor 11 is fixed to the bottom of the drone body 10. The output end of the yaw axis motor 11 is connected to the two-axis gimbal 12 via a connector 16. The two-axis gimbal 12 includes a gimbal base plate 121, a gimbal side plate 122, and a connecting plate 123. The connecting plate 123 is fixed to the gimbal base plate 121 and hinged to the gimbal side plate 122. The top of the gimbal side plate 122 is connected to the connector 16. The two ends of the connecting rod 15 are rotatably connected to the gimbal side plate 122 and the crank 14, respectively. The crank 14 is located outside the output end of the pitch axis motor 13, and the pitch axis motor 13 is fixed on the connecting plate 123. The fire extinguishing assembly includes a dry powder fire extinguishing tank 17, a dry powder nozzle 18, and a water-based fire extinguishing nozzle 19. The dry powder fire extinguishing tank 17 is located on the top of the UAV body 10. The dry powder nozzle 18 and the water-based fire extinguishing nozzle 19 are respectively located on the gimbal base plate 121, and the dry powder nozzle 18 and the water-based fire extinguishing nozzle 19 are respectively connected to the dry powder fire extinguishing tank and the fire hose.

[0017] Using the above structure, the fire extinguishing assembly achieves flexible, large-angle spraying in the yaw and pitch axis directions through the coordinated operation of the yaw axis motor 11 and the pitch axis motor 13. Specifically, the yaw axis motor 11 drives the two-axis pan-tilt unit 12 to rotate along the yaw axis, allowing the fire extinguishing assembly to cover a 360° horizontal fire source area. When the output end of the pitch axis motor 13 drives the crank 14 to rotate, the crank 14 drives the connecting rod 15 to rotate. However, since the vertical direction of the pan-tilt unit side plate 122 is fixed, and the crank 14, connecting rod 15, pan-tilt unit side plate 122, and pan-tilt unit base plate 121 form a quadrilateral structure, the pitch axis motor 13 and the connecting plate 123 rotate under the action of interaction forces. The connecting plate 123 rotates around the hinge point with the pan-tilt unit side plate 122, thereby driving the pan-tilt unit base plate 121 to rotate along the pitch axis, thus adjusting the vertical direction of the fire extinguishing assembly.

[0018] Specifically, the fire extinguishing component can be adjusted at multiple angles in the pitch and yaw axes, thereby expanding the range of spray fire extinguishing and flexibly adapting to the fire source location in high-rise cast-in-place facades, windows, or complex spaces, thus improving fire extinguishing efficiency.

[0019] By setting up dry powder fire extinguishing tank 17, dry powder nozzle 18 and water-based fire extinguishing nozzle 19, the system can freely switch between dry powder fire extinguishing agent and water-based fire extinguishing agent according to the actual situation on site.

[0020] By equipping drones with fire extinguishing components and a two-axis gimbal 12, they can quickly reach the scene in the early stages of a fire and extinguish it using a combination of dry powder and water-based fire extinguishing agents, thereby shortening the firefighting time.

[0021] In an embodiment of this utility model, a flow rate control valve is also included, which is disposed on the dry powder spray pipe 18.

[0022] The flow rate and velocity of the dry powder extinguishing agent are adjusted by a flow rate control valve.

[0023] In an embodiment of this utility model, an industrial camera 21 and an image transmission module 22 are respectively provided on the gimbal base plate 121.

[0024] The industrial camera 21 and the image transmission module 22 transmit real-time images of the fire scene to the command center, so that staff can adjust the spray angle and horizontal direction of the extinguishing agent and the type of extinguishing agent to be used for fire extinguishing based on the image situation.

[0025] In an embodiment of this utility model, the dry powder nozzle 18 is located above the gimbal base plate 121, the water-based fire extinguishing nozzle 19 is located below the gimbal base plate 121, and the industrial camera 21 is located between the dry powder nozzle 18 and the water-based fire extinguishing nozzle 19.

[0026] After the industrial camera 21 captures the location of the fire source in real time, the staff can adjust the spray direction of the powder nozzle and the water nozzle according to the camera image, so as to ensure that while monitoring the fire in real time, the spray direction of the dry powder nozzle 18 and the water extinguishing nozzle 19 can be accurately aimed at the fire source.

[0027] In the embodiments of this utility model, the dry powder nozzle 18 and the water-based fire extinguishing nozzle 19 are respectively fixed to the top and bottom surfaces of the gimbal base plate 121 by detachable clamps 20.

[0028] The dry powder nozzle 18 and the water-based fire extinguishing nozzle 19 are fixed by detachable clamps 20, which facilitates the disassembly and replacement of the dry powder nozzle 18 and the water-based fire extinguishing nozzle 19.

[0029] Specifically, the detachable clamp 20 includes a fixed clamp, a movable clamp, and a fixing nail. By fixing the fixed clamp to the base plate 121 of the pan-tilt unit, the dry powder nozzle 18 or the water extinguishing nozzle 19 is installed in the groove of the fixed clamp, and the movable clamp is installed on the top of the fixed clamp by the fixing nail, thereby fixing the position of the dry powder nozzle 18 or the water extinguishing nozzle 19.

[0030] Implementation process: Using the above structure, the fire extinguishing assembly achieves flexible spraying at large angles along the yaw and pitch axes through the coordinated operation of the yaw axis motor 11 and the pitch axis motor 13. Specifically, the yaw axis motor 11 drives the two-axis pan-tilt unit 12 to rotate along the yaw axis, thereby enabling the fire extinguishing assembly to cover a 360° horizontal range of the fire source area. When the output end of the pitch axis motor 13 drives the crank 14 to rotate, the crank 14 drives the connecting rod 15 to rotate. However, since the vertical direction of the pan-tilt unit side plate 122 is fixed, and the crank 14, connecting rod 15, pan-tilt unit side plate 122 and pan-tilt unit base plate 121 form a quadrilateral structure, under the action of interaction forces, the pitch axis motor 13 and the connecting plate 123 rotate. The connecting plate 123 rotates around the hinge point with the pan-tilt unit side plate 122, thereby driving the pan-tilt unit base plate 121 to rotate along the pitch axis, thus achieving adjustment of the vertical direction of the fire extinguishing assembly.
