Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to an integrated ground-air multi-functional fire extinguishing system. Background Technology

[0002] Traditional firefighting operations primarily rely on close-range spraying from fire trucks, firefighters carrying equipment into the fire scene, and helicopter water droplets. Common firefighting equipment structures in current technology include: ordinary wheeled fire trucks equipped with water tanks and water cannons, relying on engine-driven pumps for spraying, suitable for building fires on urban roads; high-pressure water cannons, using folding booms to deliver water cannons to heights of tens of meters, used for extinguishing fires on the facades of high-rise buildings; in forest firefighting, backpack fire extinguishers, portable water pumps, or helicopter water droplets are commonly used, relying on manpower or air power for targeted firefighting; for oil depot and chemical fires, foam fire trucks are used, generating foam through proportioning mixers for coverage. These equipment operate independently, lacking a systematic and coordinated design.

[0003] However, existing technologies have obvious shortcomings: mountainous terrain is treacherous, making it difficult for vehicles to enter and posing extremely high risks to personnel rescue; water evaporates easily in high-temperature fires and has weak penetrating power, resulting in low fire extinguishing efficiency; oil and chemical fires cannot be extinguished directly with water, and traditional equipment lacks versatility; there is a lack of a systematic fire extinguishing plan that can coordinate ground and air operations, operate over long distances, safely, and sustainably. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated ground-air multi-functional fire extinguishing system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An integrated ground-air multi-functional fire extinguishing system includes: a ground vehicle combat unit, an aerial bombing unit, and a fixed water sprinkler unit for high-rise buildings; the ground vehicle combat unit consists of an ice cannon launching vehicle and a water supply vehicle forming a combat module, both vehicles being equipped with independent generator sets and fast power supply connection interfaces to achieve mutual backup power supply; the ice cannon launching vehicle is equipped with a six-legged walking mechanism, a multi-tube launching device, and a vehicle-mounted ice-making device; the aerial bombing unit has a deployable fire extinguishing ice bomb compartment; the fixed water sprinkler unit for high-rise buildings is a multi-stage relay-type independent water supply sprinkler system.

[0006] As a further aspect of the present invention: a quick power supply connection interface is provided between the generators of the ice cannon launching vehicle and the water supply vehicle, so that in the event of a generator failure in either vehicle, they can be connected by cable to provide backup power to each other, ensuring uninterrupted combat operations.

[0007] As a further aspect of the present invention: the multi-tube launching device of the ice cannon launching vehicle is a three- or five-tube parallel structure, which can launch projectiles of different calibers. The launching tubes are independently controlled and support single-shot, continuous-shot or salvo firing.

[0008] As a further aspect of the present invention, the projectile medium that the multi-tube launching device can launch includes: ice bombs, dry powder bombs, foam bombs or gas extinguishing bombs, to be suitable for different types of fires.

[0009] As a further aspect of the present invention: the vehicle-mounted ice-making device manufactures high-density solid ice bullets in real time, with an ice bullet density ≥0.92g / cm³, and the ice-making device is connected to the water supply truck through a quick water pipe interface to achieve continuous ice making.

[0010] As a further aspect of the present invention: the aerial platform of the aerial bombing unit is a multi-rotor UAV or a fixed-wing aircraft, and the drop-out fire extinguishing ice bomb compartment mounted below it adopts a quick-release interface, with each compartment carrying up to one ice bomb, supporting automatic or remote-controlled individual or simultaneous dropping.

[0011] As a further aspect of the present invention: the aerial bombing unit supports multi-aircraft formation collaborative operations, with the same ground control terminal planning the flight path and drop points to form a large-scale firebreak or precisely strike high-rise fire points.

[0012] As a further aspect of the present invention: the multi-segment relay-type independent water supply sprinkler system of the fixed sprinkler unit of the high-rise building is divided into several segments according to the building height, and each segment is independently equipped with a water storage tank and a booster pump, so that the failure of any segment does not affect the operation of other segments.

[0013] As a further aspect of the present invention: the multi-segment relay sprinkler system is linked with the ground ice cannon launcher and the aerial bombing unit: the ground ice cannon launcher fires ice projectiles at the exterior wall of the building, the drone drops ice projectiles at the upper fire layer of the building, and the internal sprinkler system of the building performs internal suppression, thereby achieving three-dimensional fire extinguishing inside and outside the building.

[0014] As a further aspect of the present invention, it also includes a system coordination and control center, which is equipped with an infrared thermal imaging aiming device and a laser rangefinder for fire control calculation of ground vehicles, and for UAV flight path planning and linkage control of multi-segment water spraying systems.

[0015] Compared with the prior art, the beneficial effects of the present invention are: A comprehensive ground-air coordinated firefighting system has been established. The ground-based ice cannon vehicle utilizes a six-legged walking mechanism for all-terrain mobility and is equipped with a multi-barrel launcher and onboard ice-making equipment, enabling real-time firing of high-density ice projectiles. The aerial drone carries ice projectile containers for precise strikes at high-rise buildings and long distances. Multiple independent relay water spraying systems are installed within high-rise buildings, creating internal and external coordination. Simultaneously, both vehicles are equipped with independent generators and mutually back each other up via rapid power supply interfaces, ensuring that a single point of failure does not affect continuous operations. The fire extinguishing medium can be flexibly changed to ice, dry powder, foam, or gas, adapting to various fire scenarios such as forests, high-rise buildings, oil depots, and chemical fires.

[0016] Upon impact, the ice bomb absorbs heat, melts, and generates water vapor, achieving both cooling and suffocation in fire suppression. The ground-air coordinated system provides comprehensive coverage without blind spots, significantly improving fire suppression efficiency. Redundant power supply and multi-stage water spray design greatly enhance system reliability and safety, solving the pain points of traditional fire-fighting equipment in mountainous, high-rise, and oil-fired areas, such as poor mobility, easy interruption, and insufficient versatility.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, examples of which are illustrated in the drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or identical elements.

[0025] Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] Example 1: This example provides a ground-air integrated multi-functional fire extinguishing system, such as... Figures 1 to 4As shown, the system includes a ground vehicle combat unit 100, an aerial bombing unit 200, and a high-rise building fixed water spraying unit 300. The ground vehicle combat unit 100 consists of an ice cannon launching vehicle 110 and a water supply vehicle 120 forming a combat module. The ice cannon launching vehicle 110 adopts a six-legged walking mechanism 111, with a flat and low center of gravity design to adapt to paved roads, gravel roads, muddy mountain roads, and slopes of less than 30°. The power system of the ice cannon launching vehicle 110 is a diesel-electric hybrid power unit 112, which includes a diesel engine and a set of power batteries, and is equipped with an independent high-power generator 113. The upper part of the ice cannon launching vehicle 110 is equipped with a multi-tube launching device 114, which is a three-tube parallel structure, with each launching tube having a diameter of 80mm, and can be independently controlled to achieve single-shot, burst, or salvo firing. The ice cannon launching vehicle 110 is also equipped with an onboard ice-making device 115, which includes a refrigeration compressor, ice-making molds, and an insulated ammunition compartment. It can receive water from the water supply vehicle 120 through a quick water pipe interface 116 to produce high-density solid ice projectiles (density ≥ 0.92 g / cm³) in real time. The top of the driver's cab of the ice cannon launching vehicle 110 is equipped with an infrared thermal imaging aiming device 117 and a laser rangefinder 118 for fire scene reconnaissance and fire control calculations.

[0028] The water supply vehicle 120 is equipped with a large-capacity water tank 121 (8-ton capacity), a high-flow water pump 122 (flow rate ≥ 200L / min), and a high-pressure water gun 123. The water supply vehicle 120 is also equipped with an independent diesel-electric hybrid power unit 124 and an independent high-power generator 125. A quick-connect power supply interface 130 is provided between the ice cannon launching vehicle 110 and the water supply vehicle 120. This interface includes a waterproof and dustproof plug, socket, and a 20-meter-long high-current cable reel. In normal operating mode, the two vehicles are powered independently. If the generator of either vehicle fails, a cable connection can be completed within 30 seconds, enabling mutual backup power supply.

[0029] The aerial bombing unit 200 includes a six-rotor industrial-grade UAV 210 and a drop-type fire-extinguishing ice bomb compartment 220 mounted below it. The UAV 210 has a maximum payload of 30 kg, a flight altitude of 50-300 meters, and is equipped with an onboard downward-looking camera and a laser altimeter. The ice bomb compartment 220 uses a quick-release interface 221 and carries 12 ice bombs per compartment. The ice bomb specifications are the same as those used in the ground-based ice cannon launcher 110. The UAV 210 performs flight path planning and drop control via a ground control terminal 230, supporting automatic or remote-controlled drop of ice bombs one by one.

[0030] The fixed sprinkler unit 300 for the high-rise building is a multi-segment relay-type independent water supply sprinkler system, divided into several segments according to the building height. In this embodiment, each segment consists of 30 floors. Each segment is independently equipped with a water storage tank 310 (8-ton capacity) and a booster pump 320. The sprinkler pipes within each segment are arranged along the building's core tube, and each floor is equipped with a manual / automatic sprinkler outlet 330. Each segment operates independently, and a failure in one segment will not affect other segments.

[0031] The system also includes a system coordination and control center 400, which is located in a ground command vehicle and wirelessly connected to the control modules of the ice cannon launcher 110, the UAV ground control terminal 230, and the high-rise building fixed sprinkler unit 300 to achieve unified scheduling.

[0032] Example 2 describes the specific operational steps for using the system to fight forest fires.

[0033] A forest fire broke out in a mountainous area, with a fire line of approximately 800 meters and a slope of about 25 degrees, making it inaccessible to ordinary wheeled fire trucks. The fire department deployed a ground vehicle combat unit (110 ice cannon launchers + 120 water supply vehicles) and three drones (210).

[0034] The first step is on-site deployment. The ice cannon launching vehicle 110 uses its six-legged walking mechanism 111 to travel along a simple firebreak to a safe platform 300 meters from the fire line. The water supply vehicle 120 is parked 30 meters behind the ice cannon launching vehicle 110, and the water tank 121 is connected to the vehicle-mounted ice-making device 115 through the quick water pipe interface 116. At the same time, the cable of the quick power supply interface 130 is unfolded for standby.

[0035] The second step is ice-making preparation. The diesel-electric hybrid power unit 112 and independent generator 113 of the ice cannon launcher vehicle 110 are activated. The high-flow water pump 122 of the water supply vehicle 120 supplies water to the onboard ice-making device 115, and the refrigeration compressor starts. After 15 minutes, the first batch of high-density solid ice projectiles is completed and stored in the insulated bomb bay. During this process, the UAVs 210 complete pre-flight checks, each carrying a fully loaded ice bomb bay 220.

[0036] The third step is fire reconnaissance and targeting. Operators scan the fire line using an infrared thermal imaging aiming device 117, while a laser rangefinder 118 measures the nearest fire point at 280 meters. The thermal imaging image shows the densest area of ​​the fire line located on three adjacent hilltops. The system coordination and control center 400 synchronizes the target data to the UAV ground control terminal 230.

[0037] The fourth step is ground fire suppression. The multi-barrel launcher 114 of the ice cannon vehicle 110 fires ice projectiles at the main fire line in rapid succession. Each ice projectile shatters upon impact with the ground, melting and absorbing heat to produce a large amount of water vapor, creating a dual effect of cooling and suffocation. Each ice projectile has a coverage radius of approximately 4 meters, with a firing rate of 10 rounds per minute. After 5 minutes, the open flames on the main fire line are significantly suppressed.

[0038] The fifth step involved precision aerial strikes. Three UAVs (210) ascended to an altitude of 80 meters and, based on coordinates transmitted from the ground, flew to the three areas of concentrated fire. The ground control terminal (230) instructed the UAVs to sequentially drop ice bombs, 12 bombs per drone, creating a firebreak approximately 90 meters wide. The aerial bombing effectively covered the steep, unaffected slopes where ground vehicles could not easily engage the fire.

[0039] Step 6: Cleaning up remaining embers and continuing operations. After completing the first round of firing, the ground-based ice cannon vehicle continued making ice and firing. The high-pressure water gun 123 of the water supply vehicle 120 sprayed water to cool down the edge embers. After 25 minutes of operation, the generator 113 of the ice cannon launcher 110 overheated and shut down due to prolonged high-load operation. The operators immediately deployed the cable of the quick-connect power interface 130, connecting the generator 125 of the water supply vehicle 120 to the critical equipment (ice-making device, firing control system) of the ice cannon launcher 110. The ice cannon resumed operation 30 seconds later, and firefighting continued uninterrupted.

[0040] Step 7: Firefighting completed. After 50 minutes of coordinated ground and air operations, the open flames at the fire site were basically extinguished. Drones and ground vehicles continued to drop water and spray it on concealed smoke points until the fire was completely extinguished.

[0041] Example 3 describes the specific operational steps for using the system to extinguish fires in high-rise buildings.

[0042] A fire broke out on the 20th floor of a 120-meter-tall (approximately 40-story) office building. The internal automatic sprinkler system had failed due to years of disrepair, and the fire was spreading upwards.

[0043] Step 1: Ground Deployment. A group of ground vehicle combat units arrives at the safe area below the building (100 meters away). The ice cannon launcher vehicle 110 adjusts the elevation angle of the multi-barrel launcher 114 to 45°, preparing to launch ice projectiles at the 15th to 25th floors of the building facade. Two drones 210 are on standby.

[0044] The second step involves cooling the building's exterior and breaking windows. Ice cannon vehicles (model 110) fire ice projectiles at a moderate rate of fire (6 rounds per minute) at the burning floor and the two floors above it. Upon impact with the glass curtain wall, the ice projectiles shatter, and the broken ice and water vapor absorb heat, lowering the exterior temperature. Simultaneously, they shatter some window glass, creating a path for subsequent aerial bombing.

[0045] The third step involves aerial bombing to suppress the indoor fire. Two drones, 210, ascend to the 22nd and 18th floors respectively (approximately 70 meters and 55 meters), using their onboard cameras to identify the window locations on the fire floors. The ground control terminal 230 sets the dropping coordinates, and the drones sequentially drop ice bombs into the room. After entering the room through the window, the ice bombs impact the walls or floor, releasing water mist and dry powder (in this embodiment, the ice bombs are pre-loaded with ABC dry powder), effectively suppressing the indoor flames.

[0046] The fourth step involves the activation of the internal sprinkler system. The office building is equipped with the multi-segment sprinkler system 300 of this invention, with floors 16-30 forming the third segment. Upon the fire, the fire control center remotely activates the independent water storage tank 310 and booster pump 320 for this segment. Sprinkler pipes within the segment spray water into corridors and rooms through sprinkler nozzles 330 on each floor. Because each segment operates independently, the segments below the fire floor are unaffected. Firefighters can ascend the fire escape stairs from the ground floor to the 15th floor and utilize the safe environment of the unactivated segments to launch an interior attack.

[0047] The fifth step involved coordinated ground and air operations. Ground-based ice cannons continuously fired cooling spray at the building's exterior to prevent the fire from spreading to higher floors; drones hovered outside the windows of the floor where the fire originated, providing secondary sprays to areas where the fire might reignite; and the building's internal sprinkler system remained operational. After one hour of coordinated efforts, the fire was brought under control, and firefighters entered the 20th floor to complete the final cleanup.

[0048] Step 6: Power supply backup. If the generator of the ice cannon vehicle fails, the power supply is quickly switched to the water supply vehicle to ensure uninterrupted launch. No failure occurred in this embodiment, but the backup system was in standby mode.

[0049] Example 4 describes the specific operational steps for using the system to extinguish a Class B oil fire.

[0050] A fire broke out in a tank area of ​​an oil depot. The tanks contained gasoline, and it was strictly forbidden to extinguish the fire directly with water.

[0051] The first step is to change the extinguishing medium. The projectiles equipped on the multi-tube launcher 114 of the ice cannon launcher vehicle 110 are replaced with foam ice projectiles—the outer shell of which is high-density ice, and the interior is encapsulated with aqueous film-forming foam liquid. The specifications of the ice projectiles are the same as those of ordinary ice projectiles. At the same time, the UAV's ice projectile compartment 220 is filled with dry powder ice projectiles (internal encapsulated with ABC dry powder).

[0052] The second step involved covering the ground with foam. The ice cannon launcher, vehicle 110, positioned itself 200 meters upwind of the oil tank and fired foam ice projectiles at the tank wall in a salvo. Upon impact, the projectiles ruptured, releasing foam liquid that spread across the surface of the liquid inside, forming a foam layer that isolated the air and suppressed oil vapor evaporation. After firing 20 foam ice projectiles consecutively, the foam coverage on the liquid surface reached a thickness of 3 cm, and the open flames were significantly reduced.

[0053] The third step involved precision aerial strikes. Two UAVs, each carrying a dry powder ice bomb, flew to a position 50 meters above the top of the oil tank and precisely dropped the bombs on complex areas such as the breather valve and gauging port. The dry powder ice bombs then released dry powder upon rupture, covering these easily reignited points and completely extinguishing any remaining flames.

[0054] The fourth step is continuous cooling. After the fire is extinguished, the water supply vehicle 120 uses a high-pressure water gun 123 to cool the outer wall of the tank to prevent reignition. Throughout the process, direct water jets were not used to impact the oil surface, thus avoiding the risk of boiling over or splashing.

[0055] Example 5 describes the verification steps for the system power supply redundancy design.

[0056] Under simulated combat conditions, the independent generator 113 of the ice cannon launcher 110 was manually shut down due to a malfunction to test the system's continuous working capability.

[0057] Before the test, both vehicles were in normal working condition, and the cable of the fast power supply connection interface 130 was not connected. The multi-barrel launcher 114 and the on-board ice-making device 115 of the ice cannon launcher vehicle 110 are powered by their own generator 113. The water supply vehicle 120 operates independently.

[0058] Minute 0: The generator 113 of the ice cannon launcher stops, the on-board ice-making device 115 stops working, and the control circuit of the multi-tube launcher 114 is de-energized.

[0059] 0.5 minutes: The operator takes the cable of the quick power connection interface 130 from the water supply vehicle 120, inserts it into the spare power socket of the ice cannon launcher vehicle 110, and turns on the switch.

[0060] Minute 1: Power was restored to the critical equipment (ice-making device, launch control) of the ice cannon launcher 110, and the ice-making and launch functions returned to normal. The load on the generator 125 of the water supply vehicle 120 increased but remained within its rated power (30kW).

[0061] From the 2nd to the 30th minute: Ice cannon launcher 110 operated continuously, firing 50 ice shells, and there were no further power outages.

[0062] Tests show that the fast power supply connection interface 130 can complete fault switching within 1 minute, ensuring the continuity of system operations.

[0063] Example 6 describes the multi-aircraft collaborative operation process of the aerial bombing unit.

[0064] The system is equipped with eight drones (210), all controlled by the same ground control terminal (230). In response to large-scale forest fires, operators mark a 500-meter-long firebreak on the terminal map, assigning each drone to a 50-meter-wide sub-area. The drop height is uniformly set at 80 meters, and the drop method is "simultaneous drop".

[0065] The ground control terminal 230 automatically generated eight flight paths and uploaded them to each UAV via wireless data link. The UAVs automatically took off, flew in formation, and simultaneously executed drop commands upon reaching the preset drop points. The eight UAVs dropped a total of 96 ice bombs, forming a continuous firebreak within 30 seconds. This multi-UAV collaboration reduced the operation time from 40 minutes for individual flights to 5 minutes, significantly improving firefighting efficiency.

[0066] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
