Description

Technical Field

[0002] In fire rescue operations in complex high-altitude scenarios such as high-rise buildings, forest canopies, and high-voltage transmission line corridors, drones have shown great potential due to their flexibility and accessibility. However, existing firefighting drone technology still faces a series of severe challenges in practical applications: (1) Insufficient precision operation capabilities: Traditional drones lack effective means to safely and efficiently remove small-volume obstacles or enclosed spaces at high altitudes, making it difficult to open fire-fighting channels or eliminate ignition hazards; (2) Limited fire-fighting efficiency: Existing fire-fighting bomb throwing devices generally rely on manual loading or simple release mechanisms, making it difficult to achieve continuous, automatic throwing and rapid reloading of fire-fighting bombs during flight, resulting in low fire-fighting efficiency and difficulty in coping with rapidly spreading fires; (3) Poor flight stability: The strong thermal turbulence environment unique to fire scenes can easily cause drones to lose control of their attitude or even crash, seriously threatening operational safety; (4) Fragile system reliability: The high temperature, electromagnetic interference, and complex airflow at fire scenes pose a severe test to the key actuators and sensor systems of drones.

[0036] Example 2:

[0037] See also Figures 1 to 8 Compared with the first embodiment, the fire inspection drone with self-checking control of the present invention further includes: the control component 3 includes a magnetic shield 31 fixedly installed at the bottom of the arm of the rotor component 2 by bolts, and the side of the magnetic shield 31 is connected to the row of electromagnetic valves 433 by a connecting pipe; a heat-conducting tube 32 is fixedly installed in a U-shaped structure inside the magnetic shield 31; a first electrode plate 33 is fixedly installed on the front and rear sides of the heat-conducting tube 32 by bolts, and an ion fluid 34 for conducting electricity is provided inside the heat-conducting tube 32; a first permanent magnet 35 is fixedly installed on the left and right sides of the heat-conducting tube 32 by bolts; and a first sensor component 36 for data acquisition is fixedly installed on the bottom of the heat-conducting tube 32 by bolts.

[0038] The first sensor assembly 36 includes a temperature sensor and a current sensor; the temperature sensor is attached to the outer wall of the heat-conducting tube 32, and the current sensor is connected in series to the power supply circuit of the first electrode plate 33; the output ends of the temperature sensor and the current sensor are connected to the single-cell controller 45; the second sensor assembly 437 is specifically an infrared sensor.

[0039] The working principle of the fire inspection drone with self-checking control is as follows:

[0040] First, when using this device, first place the device in the working area, then connect the device to an external power source to provide the power required for the device to work;

[0041] Second, the ground personnel drive the UAV body 1 to fly on the inspection route through the control terminal, and the sensor on the top side of the single controller 45 scans the location of the fire source, and the data is fed back to the single controller 45; the single controller 45 supplies energy to the propulsion cylinder 423 and the annular coil 421 respectively, and the annular coil 421 is energized to generate magnetism and attract the cast iron ring 422 at the end of the propulsion cylinder 423, so that the propulsion cylinder 423 can adjust the angle with the assistance of the rotating ball 424, and a pulse current is passed through the electromagnetic coil inside the propulsion cylinder 423 to generate an alternating magnetic field, which interacts with the permanent magnet block on the surface of the sliding rod 425, driving the sliding rod 425 along the propulsion cylinder 42 3. Axial acceleration and ejection. Here, the throwing rod 428 at the end of the sliding rod 425 can slide out and drag a bird's nest or a small pile of dead wood at the fire scene, or break a glass window. At the same time, the first coil block 427 at the front end of the sliding rod 425 can stop supplying energy to it, so that it stops adsorbing the throwing rod 428, so that the throwing rod 428 can be ejected according to the kinetic energy of the sliding rod 425. This is suitable for high-altitude firefighting in woods, high-voltage power lines or floors. The small air pump 432 and the row of solenoid valves 433 provide air pressure to the first pneumatic turntable 434, which drives the winder 435 to reel in and limit the rope 426 and the sliding rod 425.

[0042] Third, the single-unit controller 45 applies voltage to the memory alloy 444 through the power switch 445 and forms an electric field loop with the assistance of the second electrode plate 443. The loop current heats the memory alloy 444, causing it to deform due to heat, pushing the first rotating plate 442 to rotate around the axis. Here, the first rotating plate 442 and the second rotating plate 449 are separated from each other, so that the second rotating plate 449 pulls the reset spring 4410 to rotate under the gravity factor of the fire extinguishing bomb. Here, the fire extinguishing bomb is separated from the second rotating plate 449 to complete the throwing action, and the reset spring 4410 pulls the second rotating plate 449 to reset. At the same time, the first rotating plate 442 rotates to the side of the bottom cross frame of the bomb rack 4310, and the infrared sensor in the second sensor assembly 437 detects the rotation of the first rotating plate 442. Since the first rotating plate 442 and the bomb rack 4310 are set to be staggered front and back, and it takes a short time for the memory alloy 444 to change from temperature to deformation under the airflow of the rotor assembly 2, a small air pump is used here. The gas in 432 and the row of electromagnetic valves 433 enters the second pneumatic turntable 438 and drives the rotating chuck 439 to rotate. The toothed outer ring surface of the rotating chuck 439 rotates to push the fire extinguishing bombs on the bomb rack 4310 to slide down one by one to the bottom horizontal plate of the bomb rack 4310. During the rebound process of the first rotating plate 442, the short rod at the bottom will contact the top hanging ring of the fire extinguishing bomb, and the second permanent magnet 447 will provide a small adsorption force to the top hanging ring of the fire extinguishing bomb, so that the first rotating plate 442 During the rotation process, the fire extinguishing bomb on the horizontal plate of the bomb rack 4310 can be driven into the interior of the side loading box 441. After the first rotating plate 442 rotates to its correct position, the second coil block 446 is energized to generate a magnetic field that drives the second permanent magnet 447 to move in the chute. The sliding inertia of the second permanent magnet 447 and the impact force between the second permanent magnet 447 and the chute wall of the first rotating plate 442 enable the fire extinguishing bomb to slide out of the first rotating plate 442 and slide into the interior of the second rotating plate 449, thus automatically completing the loading of the bomb.

[0043] Fourth, when the drone body 1 encounters strong turbulence in the fire scene, the drone's attitude changes rapidly. Due to inertia, the ionic fluid 34 in the cavity produces relative motion in the cavity. The relative motion direction of the ionic fluid 34 is perpendicular to the direction of the static magnetic field established by the first permanent magnet 35. According to Faraday's law of electromagnetic induction, the moving ionic fluid 34 cuts the magnetic flux lines, and an electromotive force is induced inside the ionic fluid 34 along a direction perpendicular to both the magnetic field direction and the motion direction of the ionic fluid 34. Since the ionic fluid 34 is conductive, the induced electromotive force drives the current to flow inside the ionic fluid 34. The current path forms a closed loop through the first electrode plate 33. The current flowing here is in the magnetic field and will be subject to a Lorentz force according to the Lorentz force law. The direction of this Lorentz force is perpendicular to both the current direction and the magnetic field direction. Since the direction of the Lorentz force always hinders the movement of the conductive fluid relative to the magnetic field, this force acts on the fluid ion fluid 34 to resist the movement trend of the ion fluid 34 relative to the cavity. The ion fluid 34 will also exert an equal and opposite force on the cavity wall, i.e., the drone structure. The reaction force exerted by the fluid on the cavity wall forms a damping torque, which acts on the rotor assembly 2 and the drone body 1 to resist sudden changes in its posture. At the same time, the first sensor assembly 36 is used to detect temperature-related data inside the heat-conducting tube 32, and the data is transmitted in real time to the single-unit controller 45 to determine system abnormalities and trigger alarms or shutdown commands.

[0044] The present invention provides an improved fire inspection drone with self-checking control. The drone scans the fire source and centrally controls it through a single controller 45. The sliding rod 425 and the casting rod 428 are pushed out at high speed by the hook rope assembly 42 to clear bird nests, dead wood, or break windows to open the way. Based on the temperature-controlled deformation of the memory alloy 444 and the pneumatic-magnetic cooperative mechanism, the drone can automatically cast and continuously load fire extinguishing bombs. When encountering strong turbulence, the built-in ionic fluid 34 cuts the static magnetic field of the first permanent magnet 35 to generate Lorentz force damping, actively suppressing sudden changes in posture. At the same time, key parameters are monitored to ensure safety, integrating the four functions of detection, demolition, fire extinguishing and stabilization into one.
