Description

TECHNICAL FIELD

[0001] The present application relates to the field of fire extinguishing devices, in particular to a portable fire extinguishing device for unmanned aerial vehicle. BACKGROUND

[0002] In fire rescue, the use of unmanned aerial vehicles carrying fire extinguishing devices can quickly reach the fire scene, especially in areas where personnel are difficult to reach, thereby improving rescue efficiency and protecting the safety of rescue personnel.

[0003] Currently, unmanned aerial vehicles carrying fire extinguishing balls are one of the common fire extinguishing methods. In actual operation, the unmanned aerial vehicle delivers the fire extinguishing ball directly above the fire point, and then releases the fire extinguishing ball, which breaks above the fire source, so that the internal fire extinguishing agent quickly covers the fire source, thereby achieving the purpose of extinguishing the fire.

[0004] However, the existing fire extinguishing ball mainly relies on a timer to control the release time of the fire extinguishing agent, and the set time of the timer is fixed at the factory, which cannot be flexibly adjusted according to the complex situation of different fires in actual rescue. This limitation leads to the fact that the starting and extinguishing effect of the fire extinguishing ball are subject to the flight height of the unmanned aerial vehicle. In order to make the fire extinguishing ball have enough response time, the unmanned aerial vehicle needs to fly at a high altitude, and when the unmanned aerial vehicle flies at a low altitude, the timer may set the time too long, causing the fire extinguishing agent to be released deep into the flame. At this time, the fire extinguishing agent breaks in the fire source, which may be hindered by the high temperature and strong airflow of the flame, thereby affecting the extinguishing effect.

[0056] In some embodiments, the fixed shell 1 comprises a shell 11, a fixed ring 12, a filling cavity 13, a plurality of grooves 14, the shell 11 can be spherical, and can be made of high-strength and flexible engineering plastic, which can not only ensure that the fixed shell 1 will not be easily damaged during daily transportation and storage, but also can quickly break when impacted by the blasting assembly 4 to release the fire extinguishing substance, the fixed ring 12 is arranged at the top of the shell 11 and connected with the connecting ring 21, which can be connected by threads, and the threaded connection between the fixed ring 12 and the connecting ring 21 can be filled with sealant to achieve sealing when the sealing assembly 2 is connected with the mounting assembly 3, to avoid leakage of the fire extinguishing substance and to enhance the structural stability of the entire device, ensuring that all parts of the device remain tightly connected during the flight of the unmanned aerial vehicle and at the moment of blasting, without loosening or separating, the filling cavity 13 is provided with the blasting assembly 4 and filled with fire extinguishing substance, which can ensure that enough impact force is generated when starting to make the fixed shell 1 quickly break and evenly and fully diffuse the fire extinguishing substance around the fire source, the plurality of grooves 14 are arranged in a ring shape on the surface of the shell 11, which can guide the breaking direction when the fixed shell 1 is impacted by the blasting, so that the fixed shell 1 breaks more quickly and evenly along the distribution of the grooves, thereby improving the release efficiency of the fire extinguishing substance, and the grooves 14 can also act as reinforcing ribs to improve the overall strength of the fixed shell 1, so that it can better withstand external forces during transportation and flight, and can guide the passage of air flow during the descent of the fire extinguishing device to improve the stability of the descent process and thus improve the accuracy of the falling position of the fire extinguishing device.

[0057] In some embodiments, the blasting assembly 4 comprises a blasting pipe 41, a blasting substance 42, and an ignition head 43, the blasting pipe 41 is arranged in the fixed shell 1, and the blasting pipe 41 is surrounded by fire extinguishing substance to stably install the blasting pipe 41 in the fixed shell 1 and ensure that it will not shift or shake during transportation and flight, the blasting substance 42 is filled in the blasting pipe 41, which can be a pyrotechnic composition, the composition and proportion of the pyrotechnic composition can be adjusted according to different use scenarios, the ignition head 43 is inserted into the blasting substance 42 and electrically connected with the control assembly 5, which can be connected by high-temperature-resistant and anti-interference wires, the ignition head 43 uses a high-sensitivity electronic ignition device that can quickly generate a high-temperature spark after receiving the electrical signal from the control assembly 5 to ignite the blasting substance 42, and the control assembly 5 can precisely control the ignition time and ignition energy of the ignition head 43 to achieve precise detonation of the blasting substance 42.

[0058] In some embodiments, the explosive 42 can be liquefied carbon dioxide, which can utilize the huge expansion force generated when it instantaneously gasifies to achieve the blasting effect.

[0060] In some embodiments, the control assembly 5 comprises a control board 51, a battery 52, a start switch 53, and a plug 54. The control board 51 is fixedly arranged in the sealing assembly 2 and is electrically connected with the blasting assembly 4. The control board 51 can adopt a high-integration and low-power chip set, which is firmly fixed inside the sealing assembly 2 through miniaturized design and can be fixed by glue. The control board 51 is electrically connected with the blasting assembly 4 through a wire with strong anti-interference ability. The control board 51 can be provided with a timing module, which can receive and process signals and send precise control instructions to the blasting assembly 4 to realize precise start of the blasting assembly 4. The battery 52 is fixedly arranged in the sealing assembly 2 and is electrically connected with the control board 51. The battery 52 can be a high-capacity, lightweight and stable lithium battery, which is also firmly installed in the sealing assembly 2 to provide continuous and stable power source for the control board 51 and the entire control assembly 5, ensuring that all components can operate normally during the entire fire extinguishing operation and will not affect the fire extinguishing effect due to insufficient power. The start switch 53 is arranged on the control board 51 and can control the circuit communication and disconnection between the control board 51 and the battery 52. When the start switch 53 is closed, the circuit between the control board 51 and the battery 52 is connected, and the entire control assembly 5 starts to work. When the start switch 53 is disconnected, the circuit is cut off, and the control assembly 5 is in standby state. The plug 54 penetrates the sealing assembly 2, one end of the plug 54 is pressed on the start switch 53, and the plug 54 can be fixed on the sealing assembly 2. The plug-in fitting structure of the plug 54 and the sealing assembly 2 is prior art, which will not be described here. Before the fire extinguishing device is ready for use, the plug 54 is in the inserted state, and the start switch 53 remains disconnected to prevent accidental start of the device. When the device needs to be started, the operator only needs to easily pull out the plug 54, and the start switch 53 will quickly act under the action of the internal mechanical structure to realize circuit communication and prepare for subsequent blasting operation.

[0061] In some embodiments, the starting switch 53 comprises a starting block 531, a starting groove 532, a first connecting piece 533, a second connecting piece 534, a movable piece 535, a reset spring 536, and a pressing piece 537. The starting block 531 is made of high-strength insulating material and is firmly arranged on the control panel 51, providing a solid and reliable installation basis for other components of the starting switch 53. The starting groove 532 is arranged in the starting block 531, and the movable piece 535 can smoothly slide in the starting groove 532. The movable piece 535 is made of conductive metal such as copper. The first connecting piece 533 is made of high-conductivity metal material and is firmly fixed on the inner wall of one side of the starting groove 532. It can be electrically connected with the control panel 51 by welding. The second connecting piece 534 is also made of high-quality conductive material and is fixed on the inner wall of the other side of the starting groove 532. It is connected with the battery 52. The reset spring 536 is arranged between the bottom of the movable piece 535 and the control panel 51. The pressing piece 537 is arranged on the top of the movable piece 535 and is attached to the bottom of the plug 54. The pressing piece 537 is made of insulating material such as plastic. The top of the pressing piece 537 near the side of the plug 54 is arc-shaped, which facilitates the insertion of the plug 54 and the downward movement of the pressing piece 537.

[0062] When the plug 54 is inserted, the pressing piece 537 is pressed by the plug 54, which presses the movable piece 535 downward, causing the first connecting piece 533 and the second connecting piece 534 to separate, and the circuit is disconnected. When the plug 54 is pulled out, the pressing piece 537 loses pressure, and under the action of the elastic force of the reset spring 536, the movable piece 535 quickly slides upward, causing the first connecting piece 533 and the second connecting piece 534 to communicate through the movable piece 535, realizing the conduction of the circuit, and thus successfully starting the device.

[0063] In some embodiments, the control assembly 5 further comprises a fixed wire, a fixed column 55, a deformation conductive piece 56, and a heat-conducting rod 57. The fixed wire is made of high-temperature-resistant and wear-resistant wire and is connected between the positive electrode of the battery 52 and the blasting assembly 4, providing stable power supply for the blasting assembly 4 and ensuring that the required energy at the moment of blasting can be transmitted in time and accurately. The fixed column 55 is arranged on the control panel 51 and can be electrically connected with the blasting assembly 4 by welding or wire. One end of the deformation conductive piece 56 is connected with the negative electrode of the battery 52, and the other end is bent and arranged on one side of the fixed column 55. The deformation conductive piece 56 is made of special heat-sensitive material, such as shape memory alloy. When the external temperature changes, its shape will change accordingly, so that it deforms and connects with the fixed column 55 when heated. The heat-conducting rod 57 is connected with the deformation conductive piece 56 at the top and extends to the outside of the fixed shell 1 at the bottom, directly exposed to the external environment. When the fire extinguishing device falls from the unmanned aerial vehicle to the fire source, the temperature of the heat-conducting rod 57 rises by about 1° due to air resistance and frictional heating. This temperature rise does not affect the deformation conductive piece 56, thereby avoiding the misoperation of the deformation conductive piece 56.

[0064] When the heat-conducting rod 57 senses high temperature from the outside, such as being close to a fire source, it will quickly transfer heat to the deformed conductive sheet 56. After the deformed conductive sheet 56 is heated, it deforms and is connected with the fixed column 55, thereby making the circuit between the blasting assembly 4 and the battery 52 conductive, the blasting assembly 4 works, and automatic blasting is achieved, thereby increasing the intelligence and adaptability of the fire extinguishing device, enabling it to automatically respond according to the actual situation in complex and variable fire scenes, and timely and effectively extinguishing the fire.

[0065] The specific working principle is as follows:

[0066] In specific use, first, the unmanned aerial vehicle mounting rack is connected with the mounting plate 32 through the mounting hole 33, the hook, the latch and other connecting components, the fire extinguishing device is mounted on the unmanned aerial vehicle, and the latch 54 at the end is tied to the unmanned aerial vehicle through a connecting rope, thereby achieving the installation of the fire extinguishing device on the unmanned aerial vehicle.

[0067] The unmanned aerial vehicle carries the fire extinguishing device to fly to a suitable position above the fire source. In this process, the control assembly 5 is in an unstarted state, the latch 54 is pressed on the starting switch 53, and the circuit between the control board 51 and the battery 52 is disconnected.

[0068] The unmanned aerial vehicle releases the fire extinguishing device, and the fire extinguishing device freely falls under the action of its own gravity. At this time, the latch 54 that penetrates the sealing assembly 2 and is pressed on the starting switch 53 is pulled out, the latch 54 is away from the pressing sheet 537, the movable sheet 535 slides under the action of the reset spring 536, the first connecting sheet 533 and the second connecting sheet 534 are connected through the movable sheet 535, the control board 51 is powered on, and the control assembly 5 starts to work.

[0069] After the control board 51 receives a signal (which can be a timer to a set time point), the signal is sent to the ignition head 43, the ignition head 43 quickly generates a high-temperature spark after receiving the signal, and ignites the blasting material 42 in the blasting pipe 41. The blasting pipe 41 is filled with fire extinguishing substances around, the explosion energy is released through the blasting port 44 and the blasting pipe 41, the fixed shell 1 is quickly broken under the impact force of the explosion energy, the fire extinguishing substances are quickly and timely sprayed to the surrounding, the fire source is uniformly covered, and the fire extinguishing is achieved.

[0070] When the ignition head 43 does not receive the signal, and the heat-conducting rod 57 senses high temperature from the outside, such as being close to a fire source, the heat-conducting rod 57 will quickly transfer heat to the deformed conductive sheet 56, the deformed conductive sheet 56 deforms and is connected with the fixed column 55, making the circuit between the battery 52 and the blasting assembly 4 conductive, the ignition head 43 ignites the blasting material 42, automatic blasting and fire extinguishing are achieved, thereby increasing the intelligence and adaptability of the fire extinguishing device, enabling it to automatically respond according to the actual situation in complex and variable fire scenes, and timely and effectively extinguishing the fire, reducing the influence of the flight height of the unmanned aerial vehicle on the fire extinguishing device.
