Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire-fighting unmanned aerial vehicles, and particularly relates to a balanced water bomb throwing device, a window breaking and fire extinguishing method, a high-rise window breaking and fire extinguishing unmanned aerial vehicle and application. BACKGROUND

[0002] High-rise building fire extinguishing has been a worldwide problem. Once a fire breaks out in a high-rise or super high-rise building, it is difficult for traditional ground fire-fighting equipment to effectively implement fire-fighting rescue tasks. With the continuous development of unmanned aerial vehicle technology, the application of unmanned aerial vehicle technology in high-rise building fire-fighting has attracted much attention. When a fire breaks out in most high-rise buildings and the fire is controllable, the fire scene is usually in a closed or nearly closed state, and the fire extinguishing agent carried by the fire extinguishing unmanned aerial vehicle cannot enter the fire scene and effectively contact the fire source, resulting in further spread of the fire. In view of this problem, people have proposed a window breaking fire extinguishing scheme, but the existing several window breaking fire extinguishing schemes on the market all have certain limitations, which are analyzed as follows.

[0003] (1) Window breaking and fire extinguishing by fire extinguishing bomb

[0004] The window breaking and fire extinguishing by fire extinguishing bomb is achieved by an unmanned aerial vehicle carrying a fire extinguishing bomb and a launching device. After the fire extinguishing bomb is launched, it breaks the glass and explodes indoors, thereby achieving the purpose of fire extinguishing. Although the window breaking effect of the window breaking and fire extinguishing by fire extinguishing bomb is excellent, its defects are also particularly significant.

[0005] The high-speed flight of the fire extinguishing bomb and the fragments generated by the explosion of the projectile bring additional potential danger to the trapped personnel in the fire scene, and if there is a slight mistake, it may endanger life; the unmanned aerial vehicle will generate a certain recoil force when launching the fire extinguishing bomb, which has a high requirement for the flight stability and power system of the unmanned aerial vehicle; in order to maintain the flight stability of the unmanned aerial vehicle, the unmanned aerial vehicle is generally large in size, expensive in cost, and limited in the amount of carried bombs.

[0006] (2) Window breaking and fire extinguishing by impact of telescopic rod

[0007] The unmanned aerial vehicle is provided with a telescopic rod impact window breaking mechanism at the bottom. The telescopic rod is driven to break the glass by the conical object at the front end of the telescopic rod, and the fire extinguishing agent is sprayed through the broken window to achieve the purpose of fire extinguishing. Compared with the window breaking and fire extinguishing by fire extinguishing bomb, the advantage is that the secondary harm to the trapped personnel in the fire scene is avoided, but there are also significant defects in the impact window breaking.

[0008] The unmanned aerial vehicle is in a suspended state, and it must ensure that the telescopic rod can complete effective impact, otherwise the unmanned aerial vehicle will produce a backward displacement at the same time of impact, which will greatly weaken the impact force; if the impact can be ensured to be effective, a large reaction force will act on the unmanned aerial vehicle. The above two points are a great test for the flight stability and power system of the unmanned aerial vehicle. SUMMARY

DETAILED DESCRIPTION

[0045] In the following description, numerous specific details are given to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the present application can be practiced without one or more of these specific details. In other instances, well-known features are not described in detail to avoid obscuring the application.

[0046] To solve the problems existing in the prior art, the applicant hereby proposes a safe and reliable design scheme of a new high-altitude building window breaking fire extinguishing unmanned aerial vehicle.

[0047] Referring to Figure 1 , the high-rise window breaking coaxial dual-rotor 104 fire extinguishing unmanned aerial vehicle based on balanced launching technology is composed of a coaxial dual-rotor unmanned aerial vehicle 1, a load locking device 2, a fire extinguishing agent spraying device 3, and a balanced launching device 4.

[0048] Referring to Figure 2 , the coaxial dual-rotor unmanned aerial vehicle 1 is mainly composed of a communication module 101, an unmanned aerial vehicle power supply module 102, a rotor driving motor 103, a rotor 104, a flight control rudder module 105, a flight control module 106, and a landing gear 107. Each module is tightly linked by a screw set. The communication module 101 is located at the top of the dual-rotor 104 unmanned aerial vehicle. Its main function is to realize remote control and human-computer interaction of the unmanned aerial vehicle, realize multi-machine cooperative operation, realize real-time sharing of data such as fire site environment, fire, and distribution of trapped personnel through communication equipment, multi-machine cooperative operation, rapid control of fire, rapid extinguishing of fire sources, creation of rescue conditions, and reduction of escape risks. Complete each instruction distribution and transmit to each execution mechanism, so that each execution mechanism accurately and accurately executes the corresponding instruction. The unmanned aerial vehicle has two unmanned aerial vehicle power supply modules 102, one of which is located between the communication module 101 and the rotor driving motor 103, and the other is installed between the flight control rudder module 105 and the flight control module 106. Its main function is to provide stable power supply for the entire unmanned aerial vehicle system. The rotor driving motor 103 drives two pairs of rotors 104. The two motors inside drive the upper and lower pairs of rotors 104, respectively, and are respectively provided with a motor driver. The unmanned aerial vehicle is a coaxial dual-rotor unmanned aerial vehicle 1. The rotors 104 are fixed to the central shaft of the unmanned aerial vehicle through the rotor driving motor 103 motor rotor and bearing. The flight control rudder module 105 is located below the lower rotor 104. By mechanical pulling action, the wind angle of the lower rotor 104 is changed, so that the flight attitude of the unmanned aerial vehicle is changed. Below it is the flight control module 106. After receiving the instruction, the flight control module 106 controls the flight control rudder module 105 to complete the corresponding flight action. The fire extinguishing unmanned aerial vehicle adopts coaxial dual-rotor 104. Its structure weight and load are concentrated at the center of gravity, thereby reducing the moment of inertia of the unmanned aerial vehicle pitch and yaw, and having higher flight stability. The unmanned aerial vehicle flight control system has flight attitude sensing, collects operation environment and flight attitude data, and returns to the ground through the communication system, realizes human-computer interaction, and thus has good operability. The fuselage is relatively narrow. The unmanned aerial vehicle can flexibly avoid obstacles during flight maneuvering, which is conducive to the unmanned aerial vehicle to penetrate into a complex fire site, approach the fire source, and implement precise fire extinguishing and precise delivery of rescue materials for trapped personnel.

[0049] Referring to Figure 3, the load locking device 2 is composed of a locking upper ring 201 and a locking lower ring 202. The locking upper ring 201 is fixed to the unmanned aerial vehicle power supply module 102 below the double-rotor 104 unmanned aerial vehicle, and a locking arc-shaped locking groove is opened in the inside of the locking upper ring 201, and the locking upper ring 201 is locked with the locking flange on the top of the locking lower ring 202 through “insertion-rotation”, and the lower end of the locking lower ring 202 is linked with the load through a bolt set. The locking lower ring 202 can link multiple types of loads, in addition to the fire extinguishing device proposed in the application, it can also link rescue material bags such as emergency escape supplies. The load locking device 2 not only can make the unmanned aerial vehicle quickly replace the fire extinguishing device, greatly shorten the high-altitude fire extinguishing operation gap, but also can carry multiple loads, quickly change the “role” of rescue, and perform multiple rescue tasks.

[0050] Referring to Figure 4 and Figure 5 , the fire extinguishing agent spraying device 3 is mainly composed of a spraying device cylinder 301, a spray pipe 302, an atomizing nozzle 303, an internal pipeline 304, a pipeline joint 305, a siphon pipe 306, a fire extinguishing agent storage tank 307, a high-pressure pump 308, a storage tank mounting frame 309, and a storage tank support plate 310. The spraying device cylinder 301 is linked with the locking lower ring 202 of the load locking device 2 through a bolt set, and the load locking device 2 links it with the unmanned aerial vehicle as a whole. The fire extinguishing agent is pumped out by the high-pressure pump 308, passes through the siphon pipe 306, the internal pipeline 304, the spray pipe 302 to the atomizing nozzle 303, and is atomized and sprayed out by the unmanned aerial vehicle control to the fire source. The storage tank mounting frame 309 is linked with the spraying device cylinder 301 through a bolt set, and passes through the central square hole of the fire extinguishing agent storage tank 307, cooperates with the storage tank support plate 310, and fixes and tightens the fire extinguishing agent storage tank 307.

[0051] Referring to Figure 6 , the balance launching device 4 is linked with the storage tank mounting frame 309 through the balance launching device mounting seat 401, and the bolt set passes through the small hole at the bottom of the storage tank mounting frame 309 and cooperates with the threaded hole on the side of the balance launching device mounting seat 401. The balance launching device mounting seat 401 fixes the balance launching device 4 at the bottom of the fire extinguishing unmanned aerial vehicle.

[0052] Referring to Figure 7The balanced launching device 4 consists of a balanced launching device mounting base 401, an ignition head 402, a high-pressure chamber 403, a propellant 404, a balance body bottom thruster 405, a balance body 406, a balance body end cap 407, a sealing end cap 408, an end cap pressure ring 409, a cylinder body 410, a balance body shell 411, a propellant chamber cover 412, a pull-out bolt 413, a piston bottom thruster 414, a window-breaking water bomb piston 415, a flexible water bomb 416, and a sealing ring 410. Its working principle is as follows: When the UAV issues an ignition command, the ignition head 402 ignites and ignites the propellant 404; the air pressure in the high-pressure chamber rises instantly, and the high-pressure gas enters the cylinder 410 through the through hole of the chamber cover 412; the pressure continues to rise and continuously acts on the balance body bottom thrust 405 and the piston bottom thrust 414; when the force reaches the critical pressure at which the pull-off bolt 413 is pulled off, the pull-off bolt 413 breaks off, and the flexible water bullet 416 and the balance body shell 411 break through the sealing end caps 408 on both sides respectively; A balancing body 406, made of lightweight foamed material, absorbs energy and expands, then is slowly ejected. A flexible water bullet 416, made of a special flexible material, is ejected at a higher speed. Since the impact resistance of the sealed end cap 408 is much lower than that of the flexible water bullet 416, the flexible water bullet 416 is successfully ejected. When the flexible water bullet 416 impacts the glass at a high speed, the glass breaks upon impact, and the flexible water bullet 416 undergoes a significant change in velocity, resulting in its fracture. The window-breaking operation using the flexible water bullet 416 is then complete. This invention employs a flexible water bullet 416 window-breaking scheme. The launching device gives the flexible water bullet 416 a high initial velocity, effectively shattering the glass. Simultaneously, the flexible water bullet 416 is compressed and deformed, causing it to fracture, resulting in excellent window-breaking performance. Compared to fire extinguishing bombs, the flexible water bullet 416 does not explode. Besides the glass fragments produced upon impact, it does not produce any other potentially harmful fragments, effectively reducing the risk of secondary injury to people trapped in the fire during window-breaking operations. The flexible water bullet 416 launching device in this invention adopts balanced launching technology, with almost no recoil, reducing the strength requirements of related components of the UAV; during the window breaking operation, the fire-fighting UAV is always located on the central axis, effectively ensuring the flight stability of the fire-fighting UAV; at the same time, the balance body 406 uses lightweight foam material, which avoids the objects thrown by the balance body 406 from the fire-fighting UAV at high altitudes from causing injury to people or objects on the ground.

[0053] The firefighting drone of this invention adopts a coaxial dual rotor 104, and its structural weight and load are concentrated at the center of gravity, thus reducing the rotational inertia of the drone's pitch and yaw, resulting in higher flight stability. The drone's flight control system has flight attitude perception, collects operational environment and its own flight attitude data, and transmits it back to the ground through the communication system to realize human-machine interaction, thereby making it highly operable.

[0054] The load locking device 2 can make the unmanned aerial vehicle carry various types of loads, in addition to the fire extinguishing device proposed in the application, it can also link rescue material bags such as emergency escape goods. The device not only can make the unmanned aerial vehicle quickly replace the fire extinguishing device, greatly shorten the gap of high-altitude fire extinguishing operation, but also can carry various loads, quickly change the rescue "role", and perform various rescue tasks.

[0055] The cover fire extinguishing unmanned aerial vehicle can realize multi-machine cooperative operation, realize real-time sharing of data such as fire site environment, fire and trapped personnel distribution through communication equipment, multi-machine cooperative operation, rapid control of fire, rapid extinguishing of fire source, creation of rescue conditions and reduction of escape risk.

[0056] The fire extinguishing unmanned aerial vehicle adopts coaxial double rotors 104, the body is relatively narrow, the unmanned aerial vehicle can flexibly avoid obstacles in the process of flight maneuvering, which is beneficial to the unmanned aerial vehicle to deeply enter the complex fire site, approach the fire source and implement accurate fire extinguishing, and to explore the trapped personnel to implement accurate delivery of rescue materials.

[0057] As described above, although the application has been shown and described with reference to specific preferred embodiments, it is to be understood that the application is not to be limited to the details of the foregoing illustrated embodiments. Various changes in form and detail can be made without departing from the spirit and scope of the application as defined in the appended claims.
