[0037] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0038] In the present invention, unless otherwise stated, directional words such as "front, back, middle, inside, outside" contained in the terms merely represent the directions of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0039] See also Figures 1 to 5 The present invention provides a fire situation identification explosion fire extinguishing bomb launching device, which includes a supporting component 1, a bomb storage component 2, a fire sensing component 3 and a launching component 4. The launching component 4 is rotatably arranged on the supporting component 1 and connected to the bomb storage component 2 to fill the fire extinguishing component 44. The fire sensing component 3 is arranged on the launching component 4 and is configured to be able to control the launching component 4 to turn and launch the fire extinguishing component 44.

[0040] Through the above technical solution, the launch component 4 is rotatably arranged on the support component 1 and connected to the bullet storage component 2 to fill the fire extinguishing component 44, and the fire sensing component 3 is arranged on the launch component 4 and is configured to control the launch component 4 to turn and launch the fire extinguishing component 44. In this way, when the fire sensing component 3 detects the fire, it can drive the launch component 4 to turn and aim at the flames, and then the launch component 4 launches the fire extinguishing component 44 to the area to be extinguished for fire extinguishing. After a fire extinguishing component 44 is fired, the other fire extinguishing components 44 stored in the bullet storage component 2 will enter the launch component 4 in turn, and then the launch component 4 will continue to fire for continuous fire extinguishing until the fire is eliminated. In the whole process, the intelligent, efficient, precise and sustainable reciprocating firing greatly reduces the work intensity of firefighters, and can also perform remote unmanned fire extinguishing in special fire scenes such as toxic and harmful fires, avoiding the firefighters themselves from entering such fire scenes. The damage is very easy to cause, which is safer and more reliable. At the same time, different types of fire extinguishing components 44 can be selected for firing according to different types of fires, realizing targeted fire extinguishing operations and further improving the efficiency of fire extinguishing.

[0041] In this embodiment, in order to facilitate fixing the fire identification explosion extinguishing bomb launcher to a wall or a fixed position, preferably, a plurality of threaded holes 12 for installation and fixing are provided on the support assembly 1, and a ball joint support 13 is formed in the middle of the bottom of the support assembly 1. Further, in order to improve the stability after fixing to ensure the accuracy of launching the fire extinguishing assembly 44, it is further preferred that the threaded holes 12 include one located at the center of the support assembly 1 and a plurality of threads evenly distributed along the circumference.

[0042] In order to facilitate the installation and setting of the launch assembly 4 and realize the flexible steering of the launch assembly 4, the launch assembly 4 preferably includes a launch tube 41, the rear end of the launch tube 41 is formed with a ball joint 43 that can be matched and connected with the ball joint support 13, the front end extends outward, and a launch cavity 42 is formed inside the launch tube 41 near the ball joint support 13. Among them, a steering cavity 55 is provided on both side walls and the bottom wall of the launch cavity 42, a support rod 51 extends from the ball joint support 13, the end of the support rod 51 is connected to a steering motor 52, a steering drive wheel 54 is sleeved on the rotating shaft of the steering motor 52, and a steering drive wheel cavity is sleeved on the outside of the steering drive wheel 54, one end of a threaded rod 53 passes through the steering drive wheel cavity and meshes with the steering drive wheel 54, and the other end is formed with a universal ball and extends to be embedded in the steering cavity 55. In this way, when it is necessary to adjust the left and right steering of the launch tube 41, the steering motor 52 located on the left and right side walls can be turned on. When the steering motor 52 rotates, the steering drive wheel 54 is engaged with the threaded rod 53, which can drive the threaded rod 53 to extend or shorten. In the process of extending or shortening the threaded rod 53, the launch tube 41 can be pushed or pulled by the force of the universal ball at one end to achieve the left and right steering of the launch tube 41. Similarly, if it is necessary to raise or lower the launch tube 41, the steering motor 52 located on the bottom wall of the launch chamber 42 can be turned on, and the corresponding threaded rod 53 can be extended or contracted by the forward and reverse rotation of the steering motor 52, so as to achieve the effect of raising or lowering the launch tube 41.

[0043] In this embodiment, in order to achieve long-term and continuous firing of the fire extinguishing component 44, the bullet storage component 2 preferably includes a bullet storage tube 21 located above the firing component 4, and the bullet storage tube 21 is partially embedded in the support component 1, and is connected to the firing chamber 42 through the bellows 22.

[0044] In this embodiment, the launch assembly 4 also includes a power member 421 disposed in the ball joint 43 and a spring plate 423 disposed in the launch chamber 42. The spring plate 423 is connected to the power member 421 through a pull rod 422. A spring 424 is sleeved on the outside of the pull rod 422. The spring 424 abuts against the inner side of the spring plate 423. The fire extinguishing assembly 44 abuts against the outer side of the spring plate 423, so that the power member 421 can control the spring plate 423 to eject and excite the fire extinguishing assembly 44. At the same time, when the power member 421 pulls the pull rod 422 to compress the spring 424 and the spring plate 423, the fire extinguishing assembly 44 located in the bullet storage tube 21 can enter the launch chamber 42 along the bellows 22, realizing the launch of the fire extinguishing bomb without relying on the propellant, and safe, stable, and sustainable reciprocating launch.

[0045] In a specific embodiment, the pull rod 422 can be a threaded rod, and the power member 421 can be a driving wheel driven by a motor, which meshes with the threaded rod through the driving wheel. When the driving wheel rotates, due to the meshing action, the threaded rod retreats, and the spring plate 423 connected to the threaded rod also retreats. After the spring plate 423 retreats, it squeezes the spring 424, so that the spring 424 is gradually compressed. When firing is required, the driving wheel is controlled to disengage from the threaded rod, and the compressed spring 424 rebounds instantly and finally achieves firing.

[0046] When the fire situation identification explosive fire extinguishing bomb launching device is actually used, in order to prevent the fire extinguishing component 44 from rolling and detaching from the spring plate 423 in the launching chamber 42 after being loaded, so that the spring plate 423 cannot launch the fire extinguishing component 44 during launching, preferably, a pair of buckles 411 are provided on the outer wall of the launching tube 41 near the launching chamber 42, which are used to clamp the fire extinguishing component 44 and put it in a state ready for launching.

[0047] In addition, the fire sensing component 3 includes an infrared thermometer 31 and a smoke alarm 32 arranged on a pair of buckles 411, and a thermal imager 33 arranged at the front end of the transmitting tube 41; wherein,

[0048] The smoke alarm 32 is used to sense smoke, the infrared thermometer 31 and the thermal imager 33 are used to detect the specific position of the flame, and are configured to be able to feed back signals to the steering motor 52 so that the threaded rod 53 controls the launch tube 41 to rotate toward the flame.

[0049] In addition, the fire extinguishing assembly 44 includes a spherical polyethylene shell 441 and an explosive 443 located at the center of the polyethylene shell 441. A fuse 442 is connected between the explosive 443 and the polyethylene shell 441, and the remaining space in the polyethylene shell 441 is filled with a dry water fire extinguishing agent 444. In view of the occurrence of fires in different scenarios, the dry water fire extinguishing agent 444 is a modifiable dry water fire extinguishing agent, which forms dry water fire extinguishing bombs of different materials, thereby performing targeted explosion fire extinguishing.

[0050] To sum up, when a fire occurs, the fire identification explosive fire extinguishing bomb launching device can firstly intelligently identify the fire: when a fire occurs, it is usually accompanied by smoke, and the smoke alarm 32 first senses the smoke, and then the thermal imager 33 identifies the location of the fire and transmits the signal. The launching device can transmit power to the ball joint 43 through the power part 421 to rotate, so as to better aim at the fire and collect more fire conditions, and then use the infrared thermometer 31 to measure the fire temperature and accurately locate the fire, so as to determine the launch and quantity of the fire extinguishing component 44.

[0051] Secondly, the fire identification explosive fire extinguishing bomb launcher can explode and scatter fire: the fire extinguishing component 44 is clamped by two buckles 411 on the inner wall of the launch tube 41. After completing the intelligent identification of the fire, the feedback signal controls the buckle 411 to release the spring 424 to release the elastic potential energy, and then the spring plate 423 pushes the launch of the fire extinguishing component 44 (i.e., the explosive fire extinguishing bomb). When the fire extinguishing component 44 arrives at the fire scene, the fuse 442 senses the flame and detonates the spherical charge 443, which can explode and scatter the dry water fire extinguishing agent 444 over a larger area. The dry water fire extinguishing agent 444 uses the combined action of physical fire extinguishing and chemical fire extinguishing mechanisms when extinguishing a fire. In a specific embodiment, the dry water fire extinguishing agent 444 is prepared by mixing hydrophobic SiO2 and a salt solution in a certain proportion and stirring at high speed. The specific preparation method is:

[0052] Step 1: Add 5% NaCl into deionized water and wait until the solute is completely dissolved;

[0053] Step 2: Use an electronic weighing balance to weigh hydrophobic SiO2 and NaCl solution in a mass ratio of 1:10, mix them in a high-speed stirrer at 6000r / min for 2min.

[0054] The dry water fire extinguishing agent 444 obtained in this way has the advantages of being green, environmentally friendly and pollution-free. In addition, the dry water can be modified to achieve excellent fire extinguishing effect in response to fire extinguishing in different scenarios. For example, a workshop producing H2 can be equipped with KOH dry water fire extinguishing agent, which can suppress H2 explosion, while a workshop with a large number of wood blocks can be equipped with diammonium phosphate dry water fire extinguishing agent.

[0055] When dry water is used to extinguish a fire, the solution in the heated extinguishing agent is released, which lowers the temperature of the burning object and prevents it from reaching the ignition point. SiO2 will adhere to the surface of the burning object and isolate oxygen. The metal sodium salt solution in its core can directly interact with the flame. At the same time, it also has a shock wave fire extinguishing mechanism, which refers to the instantaneous generation of high-temperature and high-pressure gas when the explosive explodes. The gas expands rapidly and exerts a strong mechanical effect on the flame and combustibles, destroying the surface combustion layer and terminating the combustion. It can be seen that the explosion and spraying of dry water extinguishing agent 444 has both physical and chemical effects.

[0056] In addition, the fire situation identification explosive fire extinguishing bomb launching device can also re-evaluate after the fire is extinguished: after completing one fire extinguishing, the smoke alarm 32, infrared thermometer 31, and thermal imager 33 can collect data on the fire scene after the fire is extinguished again, and evaluate the explosive fire extinguishing. If it is necessary to launch fire extinguishing bombs again, it can respond to the fire more quickly and effectively.

[0057] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any appropriate manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
