Description

Technical Field

[0001] This invention belongs to the field of fire-fighting equipment technology, and specifically relates to a fire truck, particularly a multi-functional fire rescue vehicle. Background Technology

[0002] Fire trucks are commonly used firefighting equipment in modern firefighting operations. They are used for self-protection and emergency rescue when carrying out firefighting missions. Modern fire trucks mainly consist of fire water tanks, pressurized tanks, and fire ladders. When a fire occurs or someone is in danger, firefighters use the water pipes from the fire water tank and the fire ladder to carry out rescue operations.

[0003] The biggest limitation of traditional fire rescue vehicles is their inability to conduct high-altitude rescues. The length of the fire ladder increases with the rescue height, and an excessively tall ladder can lead to structural instability, making it impossible to conduct rescue operations based on the actual situation on site. Furthermore, an excessively tall fire ladder is difficult to store when not in use and is not adaptable to fire rescue vehicles of different lengths and purposes. Often, a large number of people are trapped, and rescuers cannot use the fire ladder to rescue everyone. The intensity of the fire at the scene also prevents rescuers from getting close enough, which is detrimental to both safety and rescue efficiency. A fire ladder consists of three main parts: a telescopic boom structure, a hydraulic drive unit, and a stabilizing support mechanism. The core component, the telescopic boom, uses a high-strength steel-aluminum alloy composite laminate structure. Due to the sensitivity of the telescopic boom to deflection in its fully extended state, a multi-stage hydraulic locking device and an active attitude compensation system must work together to ensure that the following key performance indicators are met simultaneously. Some technologies now also use escape tunnels, which are transported to the required height by crane or manually hung on windowsills by firefighters, allowing people to jump into the tunnel. This method can save on the height of the ladder, but it also requires operation by firefighters. It is difficult to guarantee that there is a place on the windowsill where the hook can be fixed to the pipe, and it is also impossible to ensure that there will be no danger if the fixing point is damaged midway. This brings uncertainty to the use of the escape route.

[0004] Therefore, the requirements for fire and rescue vehicles are becoming increasingly stringent. Beyond the original requirements, they must be as multifunctional as possible, capable of handling various situations and providing comprehensive rescue capabilities. Currently, many fire and rescue vehicles struggle to simultaneously meet the demands of high-rise rescue and stable safety, and this limitation significantly restricts their application in complex environments. To address these issues, a multifunctional fire and rescue vehicle has been designed, capable of high-rise rescue and able to use a combination of extinguishing agents in different fire rescue environments. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a multi-functional fire and rescue vehicle. Addressing the issues of limited functionality, low efficiency in high-altitude rescue, and poor environmental adaptability of existing fire and rescue equipment, this invention integrates a multi-functional rescue module to achieve integrated operations of efficient firefighting, rapid lifting and lowering, and precise high-altitude rescue, thus meeting diverse on-site needs.

[0006] A multi-functional fire and rescue vehicle includes a vehicle body, on which a lifting rescue platform, fire-fighting equipment, a rescue air cushion system, a multi-functional drone, and a rescue sleeve are respectively installed; the number of the lifting rescue platform is at least one, and the lifting rescue platform can be quickly installed and removed from the vehicle body; the fire-fighting equipment body is a fire tank and a storage box, the rescue air cushion system is erected above the fire-fighting equipment, and the multi-functional drone is set on the side of the fire-fighting equipment; the rescue sleeve is a long strip-shaped flexible structure, one end of which is connected to the rescue air cushion system, and the rest of the part is stacked on the vehicle body.

[0007] Furthermore, the lifting rescue platform comprises a rescue platform, support rods, telescopic rods, and a base. The support rods are scissor-brace structures, positioned between the base and the rescue platform. The lifting rescue platform achieves overall lifting by adjusting the support rods. Fixed threaded rods are provided at the intersections of the support rods. The telescopic rods are also positioned between the base and the rescue platform. The telescopic rods consist of a detachable top, middle, and bottom section connected to each other. During use, the middle section is connected and fixed to the top and bottom sections via buckles. The top and bottom sections are respectively fixed to the rescue platform. The rescue platform and base are designed so that one rescuer stands inside, while another rescuer adjusts and raises the support poles to the designated height. Simultaneously, the number of telescopic poles in the middle section is increased. By using different numbers of telescopic poles in the middle section, the rescue platform can be maintained at the required height. Multiple telescopic poles increase the load-bearing area and enhance safety. The base is designed with a mounting plate with large-diameter threaded holes, through which the lifting rescue platform is installed and removed from the vehicle body. The rescue platform is equipped with a safety railing, allowing personnel to operate safely within a certain height range and conduct rescue missions.

[0008] Furthermore, the fire-fighting equipment also includes a pressurized water outlet device, a telescopic pipe, and a nozzle. The storage box is a rectangular support structure that is connected to the vehicle body and is detachable. The fire tank is located above the storage box. The wall of the fire tank adopts a three-layer composite structure: the inner and outer surfaces are made of duplex stainless steel, and the middle buffer layer is made of uniform foamed aluminum. The inner surface of the fire tank has a narrowing section, and there is a flush step between the narrowing section and other inner walls. Spare plates are installed on both sides of the narrowing section through the steps, and the spare plates are fixed to the inside of the fire tank by pressing. The fire tank has two skylight structures on its top, which facilitates multiple personnel to enter different interiors to maintain and install / remove the spare plates. During fire rescue, different liquids and gases with different functions can also be added through the skylight structures to achieve more efficient rescue by using a combination of multiple substances.

[0009] The pressurized water outlet device is installed on both sides of the fire-fighting equipment, which can spray the fire extinguishing medium through the nozzle under high pressure. The telescopic pipe can be freely extended or shortened to meet the spraying position requirements.

[0010] The fire-fighting equipment can be used in conjunction with a lifting rescue platform, which is installed in front of the fire-fighting equipment. Workers can operate the fire-fighting equipment on the lifting rescue platform to carry out fire-fighting operations. Due to the simultaneous use of multiple fire-fighting agents and the simultaneous operation of multiple groups of workers, the fire-fighting efficiency is greatly improved.

[0011] Furthermore, the rescue air cushion system includes a main panel, a slidable sub-panel on the upper side of the main panel, and multiple telescopic support rods below the main and sub-panels. These telescopic support rods are installed around the main and sub-panels, and their cooperation with each other, in contact with the vehicle body and the ground, forms support for the main and sub-panels, serving as their supporting structure. Rescue bollards are installed around the top of the rescue air cushion system and also include rescue sleeves. Removable mesh fences are installed on the multiple rescue bollards, with openings for connecting the rescue sleeves. The rescue bollards can be added or removed as needed to achieve an effective rescue area. The mesh fences are woven and detachably connected to the rescue bollards via quick-release clips.

[0012] Furthermore, the main panel and sub-panel of the rescue air cushion system are structured with an inflatable rubber pad on a fixed bottom layer. The fixed bottom layer is made of uniform foamed aluminum material, and the two layers are connected by hot-pressing composite. In the non-working state, the rescue barrier retracts into the main panel and sub-panel, making the surfaces of the main panel and sub-panel smooth, thus allowing the sub-panel to slide and be stored on the main panel. The wire mesh is stored inside the vehicle body when not installed, awaiting rescue use.

[0013] The inflatable rubber pads on the sub-panel are twice as thick as the inflatable rubber pads on the main panel, ensuring that the top height of the inflatable rubber pads on both panels is the same when they slide out.

[0014] Furthermore, in the non-operational state, the rescue air cushion system has slides A and B between the main panel and the sub-panel, allowing them to slide together and overlap. The overlapping main and sub-panels are equipped with electrically driven rotating hinge mechanisms on their sides, which, after rotation and folding, form the side wings of the vehicle body. A cargo box structure is formed on the upper and left / right sides of the vehicle. The telescopic support rod is retracted by rotating the top of a long bolt via a bolt motor, causing the bolt sleeve to slide up and down, thus retracting the middle and bottom of the telescopic support rod to the top, reducing its overall length to one-third of its maximum. Then, the telescopic support rod is moved into the cargo box along with the retraction of the rescue air cushion system. After completion, the telescopic support rod is removed from inside the cargo box and placed inside the vehicle body. In the operational state, it forms... The main and auxiliary panels on both sides of the vehicle body are first unfolded and laid flat. Then, telescopic support rods are installed. A rotating motor rotates the top of the long bolt, causing the threaded sleeve to slide, unfolding the middle and bottom of the telescopic support rods. Finally, the system is stretched longitudinally along slides A and B to fully unfold the rescue air cushion system. It is then secured by buckles at various connection points to achieve a stable effect. At the same time, the rescue support column is extended by rotation. Once all connection points are secured with buckles, the main and auxiliary panels of the rescue air cushion system are inflated. A pressure tank is also installed on the vehicle body. Nitrogen gas from the pressure tank is introduced into the rescue air cushion system through a hose to inflate the system. This utilizes the material deformation properties to eliminate the slide rail joints, achieving a relatively flat surface.

[0015] Furthermore, the pressure tank is located behind the driver's seat of the vehicle body, adjacent to the lifting rescue platform.

[0016] Furthermore, a multi-functional firefighting drone is also provided; the multi-functional firefighting drone is equipped with a drone arm, an arm connecting rod and a drone gripper; the rescue sleeve is a cylindrical structure, and the drone gripper is used to grab the rescue sleeve fixing plate and carry the rescue sleeve for high-altitude rescue, and trapped personnel can escape by jumping into the rescue sleeve; multiple fixing points are provided at intervals on the rescue sleeve.

[0017] Furthermore, the fire-fighting multi-functional drone is equipped with a pipe wall-mounting mechanism, including a pressure cylinder, a spiral nail storage box, and an epoxy resin potting compound storage box. Pipes are installed on the spiral nail storage box and the epoxy resin potting compound storage box, and the two pipes are arranged side by side to form a double spiral nail gun nozzle. Multiple spiral nails are installed in the spiral nail storage box, and epoxy resin potting compound is stored in the epoxy resin potting compound storage box. Through the pressure cylinder, high-pressure gas synchronously delivers the spiral nails and epoxy resin potting compound stored in the nail storage box to the double spiral nail gun nozzle and sprays them out in a direction. After the spiral nails are fixed to the wall, they are used to fix the fixing point of the rescue sleeve.

[0018] Furthermore, the outer wall of the spiral nail is provided with multiple barbs, the front of the spiral nail is provided with an arrow, and a section of epoxy resin potting compound with a side opening is provided behind the arrow for storage.

[0019] Through the above technical solution, the lightweight protective and drone-assisted fire rescue vehicle of the present invention has the following beneficial effects:

[0020] 1. The fire tank in the fire-fighting equipment of the present invention has a three-layer composite structure, which improves its impact resistance and, combined with the ratio of various fire extinguishing media, effectively improves the fire extinguishing efficiency of oil / electrical fires and shortens the response time; the telescopic pipe, combined with pressurized spray, achieves a long-distance fire extinguishing radius, enabling more efficient fire extinguishing.

[0021] 2. The rescue air cushion system of this invention uses a uniform foamed aluminum material as the fixed bottom layer of an inflatable rubber pad. While reducing weight, it can also rapidly expand the inflatable rubber pad by quickly inflating it to achieve a highly efficient rescue effect. The sliding rail expansion doubles the effective area, with minimal flatness error. Combined with the quick-folding design, it makes rescue efficiency even higher. The detachable support rod and lightweight design significantly reduce the transportation volume. Furthermore, it can be folded and stored when not in use, drastically reducing its horizontal surface area and saving a lot of transportation space.

[0022] 3. By using spiral nails to fix the rescue sleeve, and by using drones to fix it on most walls, the installation time of the rescue sleeve can be greatly saved, the stability of the fixation can be improved, the adaptability to the environment can be increased, and the efficiency of fire rescue can be multiplied.

[0023] 4. The barbs of the spiral nail and the pre-embedded epoxy resin inside can achieve a double stabilizing effect. The four hooks on the outside of the rescue sleeve fixing plate can also be hung on balconies or other sturdy objects. The rescue sleeve has a rope inside. In addition to fixing itself and the rescue sleeve, the rope can also be wrapped and fixed to sturdy objects such as buildings. The cooperation between the above objects can make the rescue more safe and reliable. Attached Figure Description

[0058] Example 1

[0059] like Figure 1-25 As shown, a multi-functional fire and rescue vehicle includes a vehicle body 1, a lifting rescue platform 2, and fire-fighting equipment 3. The lifting rescue platform 2 is mounted on the vehicle body 1. Multiple threaded holes and other mounting adapters are provided on the platform surface of the vehicle body 1. Different numbers of lifting rescue platforms 2 can be installed on the vehicle body 1 according to actual needs. The lifting rescue platform 2 can be quickly installed and removed from the vehicle body 1, preferably using large bolts for fixing.

[0060] like Figure 2As shown, the lifting rescue platform 2 consists of a rescue platform 8, support rods 9, fixed threaded rods 10, telescopic rods 11, and a base 12. The lifting rescue platform 2 can achieve overall lifting by adjusting the angle and number of support rods 9 and the number of telescopic rods 11. The support rods 9 are connected by bolts, and are fixed by connecting to the fixed threaded rods 10 through a central threaded hole. The telescopic rods 11 are connected and fixed to the top 36 and bottom 38 of the telescopic rod through a buckle in the middle 37 of the telescopic rod. The telescopic rods 11 are also fixed by connecting to the rescue platform 8 and the base 12 through rotating buckles at the top and bottom. The number of telescopic rods in the middle 37 can be increased or decreased as needed to achieve auxiliary lifting and improve stability. The base 12 is designed with a mounting plate 13 with a large-diameter threaded hole 14, through which the lifting rescue platform 2 can be installed and removed from the vehicle body 1. The rescue platform 8 is equipped with a safety fence 7, allowing personnel to operate safely on it and conduct rescue missions at low and medium altitudes.

[0061] Example 2

[0062] Based on Example 1, such as Figure 3 , 7 As shown, the fire-fighting equipment 3 consists of a skylight structure 15, a fire tank 16, a storage box 17, a pressurized water outlet device 18, a telescopic pipe 19, and a sprinkler head 20. The wall of the fire tank 16 adopts a three-layer composite structure: the inner and outer surfaces are made of duplex stainless steel, and the middle buffer layer is made of uniform foamed aluminum. Figure 9 As shown, the inner surface of the fire tank 16 has a reduced diameter section 44. A flush step is provided between the reduced diameter section 44 and the other inner walls. A partition plate 45 is installed via the steps on both sides of the reduced diameter section 44, and the partition plate 45 is fixed to the inside of the fire tank 16 by pressing. The partition plate 45 has a sealing ring on its edge, and is locked to the inside of the fire tank 16 by pressing against corresponding slots on the steps on both sides of the reduced diameter section 44 using elastic buckles (not shown in the figure). The fire tank 16 is designed with two skylight structures 15, allowing multiple personnel to enter different interiors to maintain and install / remove the partition plate 45. During fire rescue, different liquids or gases with different functions can be added through the skylight structures 15, enabling the combination of various substances for more efficient rescue. The storage box 17 is fixedly connected to the bottom of the fire tank 16 and placed on both sides of the vehicle body 1.

[0063] The fire tank 16, equipped with a partition 45, can contain different extinguishing media. For example, the left-side fire equipment 3 can contain water and foam media, while the right-side fire equipment 3 can contain gaseous and dry powder media, allowing for mixed use to achieve better fire extinguishing effects. The fire equipment 3 has pressurized water outlet devices 18 on both sides, which can spray the extinguishing media at high pressure through nozzles 20. The telescopic pipe 19 can be freely extended or shortened to achieve a wider extinguishing range, better extinguishing effect, and higher extinguishing efficiency. The number of fire equipment 3 can be increased or decreased depending on the disaster situation, and they are installed on the vehicle body 1.

[0064] The fire-fighting equipment 3 can be used in conjunction with the lifting rescue platform 2, which is installed in front of the fire-fighting equipment 3. Personnel can operate the fire-fighting equipment 3 from the lifting rescue platform 2 to carry out fire-fighting operations. The simultaneous use of multiple extinguishing agents and the simultaneous operation of multiple teams greatly improves fire-fighting efficiency.

[0065] Example 3

[0066] Based on Example 2, such as Figure 4 As shown, the vehicle body 1 is also equipped with a rescue air cushion system 4, which includes rescue bollards 21, a main panel 22, a secondary panel 23, telescopic support rods 24, and a mesh fence 25. The telescopic support rods 24 are installed around the main panel 22 and the secondary panel 23. The multiple telescopic support rods 24 cooperate with each other to form the support for the main panel 22 and the secondary panel 23. The rescue air cushion system 4 is placed on the telescopic support rods 24 and held in place. The number of telescopic support rods 24 and the effective area of ​​the rescue air cushion system 4 can be adjusted according to the actual needs of use. The rescue bollards 21 are installed around the top of the rescue air cushion system 4. The bottom of each bollard 21 is rotatably secured inside the air cushion system 4 using rotating buckles. The rescue bollards 21 are often used in conjunction with the rescue sleeves 6. When trapped personnel fall directly from a height or escape through the rescue sleeves 6, some may not land precisely in a safe location. In this case, the netting 25 installed between the rescue bollards 21 on the air cushion system can effectively catch the trapped personnel and directly reduce the impact force, allowing them to land safely. The rescue bollards 21 can be added or removed as needed to achieve the desired effective rescue area.

[0067] Specifically, such as Figure 12-16As shown, the rescue air cushion system 4 consists of a rescue barrier 21, a main panel 22, a secondary panel 23, a telescopic support rod 24, and a wire mesh 25. The main panel 22 and the secondary panel 23 of the rescue air cushion system 4 are both inflatable rubber pads with uniform aluminum foam as the fixed bottom layer. This material has good impact resistance. When a trapped person jumps from a height, the main panel 22 and the secondary panel 23 will absorb a large amount of impact energy and at the same time have stability to achieve the most ideal rescue protection effect. The wire mesh 25 is made of high-density polyethylene material. This material can be stretched to twice its length while maintaining its flexibility and toughness, and can play a good blocking role at the rescue site. In the non-operating state, the rescue barrier 21 retracts directly into the main panel 22 and the sub-panel 23, making the surfaces of the main panel 22 and the sub-panel 23 smooth; the mesh fence 25 is also retracted and placed inside the vehicle body 1, awaiting the next rescue use; in the non-operating state, the main panel 22 and the sub-panel 23 slide along slide rails A56 and B57, then overlap and are placed on top of the vehicle body 1. The overlapped main panel 22 and sub-panel 23 continue to be moved through the side rotating structure (such as... Figure 13 (As shown) Rotation and folding form the side wings of the vehicle body 1, forming a complete carriage structure (as shown). Figure 12 (As shown); the telescopic support rod 24 is retracted to 1 / 3 of its original size by folding the middle part 42 and the bottom 43 of the telescopic support rod into the top 41 of the telescopic support rod. Then, the telescopic support rod 24 rotates and retracts as the rescue air cushion system 4 retracts. After completion, the telescopic support rod 24 is removed and placed inside the vehicle body 1. Specifically, the telescopic support rod 24 has a multi-layered sleeve structure with inner and outer sleeves, which are fixed together by a long bolt 59. The top of the long bolt 59 is equipped with a bolt motor 58 that cooperates with the other sleeves. Figure 21-23As shown, the telescopic support rod 24 rotates the top of the long bolt 59 via the bolt motor 58, causing the threaded sleeve 60 to slide up and down. Hinges are provided on the outer sides of slides A56 and B57, connecting an additional layer of panels. A motor can be installed at the end of the hinge's pivot to drive the pivot to rotate, ensuring the panel's angle adjustment remains a single surface with the main panel 22 and the secondary panel 23. A pin can also be installed near the hinge to ensure the stability of the resulting surface after rotation. Specifically, in the working state, the main panel 22 and the sub-panel 23 forming the two wings of the carriage will first rotate 90° around the hinge of the outer side of the slide rail A56 and slide rail B57 to unfold and lay flat. Then, the telescopic support rod 24 is installed and the middle part 42 and the bottom part 43 of the telescopic support rod are rotated and unfolded. Finally, it is stretched longitudinally along the slide rail A56 and slide rail B57 to fully unfold the rescue air cushion system 4. It is fixed by the buckles of each connecting part to achieve a stable effect. At the same time, the rescue stop 21 will also be extended by rotating. After all the connecting parts are fixed to each other, the air cushion of the main panel 22 and the sub-panel 23 in the rescue air cushion system 4 is inflated. After the preliminary work is completed, firefighters can remove the net fence 25 from the vehicle body 1 and rotate to remove all the rescue bollards 21, surrounding them with net fences 25 to prevent rescued personnel from falling out of the rescue air cushion system 4 and getting injured. One side of the net fence 25 has a special opening 55 for the rescue sleeve 6, the opening 55 being the same size as the sleeve 33, and the edges of the opening 55 have been chamfered to prevent injury to the rescued personnel. When the trapped personnel slide onto the rescue air cushion system 4 from the upper floor using the rescue sleeve 6, they slide on the main panel 22 and the secondary panel 23, and contact with the net fence 25 will also provide cushioning protection. After the main panel 22 and the secondary panel 23 are deployed, the pressure tank 53 on the vehicle body 1 can be opened, and nitrogen gas inside the pressure tank 53 can be introduced into the rescue air cushion system 4 through a hose, causing the rescue air cushion system 4 to inflate. Figure 20 As shown, the material deformation properties are used to eliminate the guide rail joints, thus achieving the desired effect. Figure 4 The effect shown allows for a specially designed inflation height, ensuring that the air cushion of the main panel 22 is raised to the same height as the air cushion of the secondary panel 23, resulting in a relatively flat surface.

[0068] like Figure 18 As shown, the pressure tank 53 is generally stored behind the driver's seat of the vehicle body 1, in the same position as the lifting rescue platform 2. When in use, simply insert a hose into the interface of the pressure tank 53 and the connector 54 of the rescue air cushion system 4 to start inflation, thereby further improving the rescue effect.

[0069] The rescue air cushion system 4 is a detachable structure that can be quickly assembled on the vehicle body 1 during operation and move quickly with the vehicle to find the best rescue location according to the situation on site.

[0070] Example 4

[0071] Based on Example 3, for height ranges where personnel evacuation and rescue cannot be directly carried out using the lifting rescue platform 2 or the rescue air cushion system 4, a multi-functional fire-fighting drone 5 and a rescue sleeve 6 are also provided for rescue. The multi-functional fire-fighting drone 5 is equipped with a drone arm 29, an arm connecting rod 30, and a drone gripper 31. When in operation, without human intervention, the drone gripper 31 of the multi-functional fire-fighting drone 5 will grab the rescue sleeve fixing plate 32 and carry the rescue sleeve 6 for high-altitude rescue. Trapped personnel can escape through the pipe by jumping into the sleeve 33. The hook 52 at the tail of the sleeve 33 is connected to the net fence 25 of the rescue air cushion system 4. After the trapped personnel jump into the sleeve 33 and come out, the rescue air cushion system 4 will provide cushioning. In non-operational state, the multi-functional fire-fighting drone 5 is placed in a box at the rear of the vehicle body 1, and the rescue sleeve 6 is placed next to the box. When needed next time, firefighters can quickly combine the multi-functional fire-fighting drone 5 and the rescue sleeve 6 together to carry out rescue missions.

[0072] The rescue sleeve 6 has multiple fixing points. The fixing points can be a ring structure set on the rescue sleeve 6, or an intermediate fixing plate set on the rescue sleeve 6, so that the rescue sleeve 6 can be used for fixing at multiple points along its entire length.

[0073] The fire-fighting multi-functional drone 5 adopts a composite anchoring integrated structure. Its tail section has a spiral nail storage box 26 and an epoxy resin potting compound storage box 27. Through pneumatic drive, the spiral nails 46 and epoxy resin potting compound 51 are synchronously delivered to the double spiral nail gun nozzle 28. Polycarbonate colloid is pre-embedded in the middle section of the nail body, preferably using Henkel LOCTITE STYCAST1068 epoxy resin, which has a curing time ≤30s. When the nail penetrates the wall, the barbs 47 on the outside of the spiral nail 46 can tightly connect with the interior of the wall, forming a stable anchoring, achieving a very ideal stable state. Simultaneously, the epoxy resin potting compound 51 ruptures due to friction with the hole wall, releasing epoxy resin, which forms a composite anchoring layer with shear strength through capillary action. The fire-fighting rescue drone 5 establishes positioning with the rescue sleeve fixing plate 32 through panel operation and launches four glued spiral nails 46 in a 2×2 array. Ballistic stability is achieved through close-range high-pressure jetting. In high-temperature environments, the surface of the nail is coated with a 0.2mm thick aerogel heat insulation layer (temperature resistant up to 650℃) to prevent the spiral nail 46 from failing to be firmly fixed due to high temperatures.

[0074] The epoxy resin potting compound 51 is used to store epoxy resin. Normally, epoxy resin is pre-filled into the epoxy resin potting compound 51 and then placed into the epoxy resin potting compound storage box 27 of the spiral nail 46. During operation, the spiral nail 46 and the epoxy resin potting compound 51 are synchronously transported to the double spiral nail gun muzzle 28 via pneumatic drive. Its transport structure is the same as existing conventional nail guns, requiring no additional transport structure design. During rescue firing, when the front end of the spiral nail 46 penetrates the wall, the epoxy resin potting compound 51 connected to its lower end is synchronously dragged into the nail hole. This epoxy resin potting compound 51 uses an ultra-thin elastic silicone shell design (preferably 0.2-0.5mm thick), which can stretch and deform under the impact of the nail, entering the wall hole with the nail. Simultaneously, the rough surface inside the wall will tear the outer membrane of the compound through friction, similar to the "jacket expansion effect" of a bullet, ultimately achieving the release of epoxy resin inside the wall hole rather than on the outer surface. Figure 10 As shown. After the spiral nail 46 is fixed to the wall, it is used to fix the life-saving sleeve 6 at multiple points, making the life-saving sleeve 6 safer to use.

[0075] The rescue sleeve 6 includes a rescue sleeve fixing plate 32, a sleeve 33, and a hook 52. The sleeve 33 of the rescue sleeve 6 is a foldable item, and the effective rescue range can be controlled by adjusting the unfolded area of ​​the sleeve 33. During operation, the fire-fighting multi-functional drone 5 uses its drone gripper 31 to grab the top hook 52 of the rescue sleeve 6 and head to the rescue site. During the rescue, the fire-fighting multi-functional drone 5 simultaneously performs the following operations:

[0076] 1. The drone gripper 31 firmly grasps the upper half of the top hook 52 of the rescue sleeve 6, and the lower half hook 52 is placed on the balcony;

[0077] 2. The fire-fighting multi-functional drone 5 uses a double-helix nail gun nozzle 28 to spray helical nails 46 into the four sides of the rescue sleeve fixing plate 32 for reinforcement;

[0078] 3. The life-saving sleeve 6 has a hook 52 at its tail that hooks onto the wire mesh 25;

[0079] 4. The inside of the sleeve 33 of the rescue sleeve 6 is assisted by the rope 50, which allows people to further slow down safely. The above operations make the rescue operation safe and stable in four ways.

[0080] 5. The sleeve 33 of the rescue sleeve 6 is made of ultra-high molecular weight polyethylene.

[0081] Example 5

[0082] The multi-functional fire and rescue vehicle provided by this solution can be adapted to various scenarios, such as:

[0083] Scenario 1: In a fire scenario in a 20-story building, the fire rescue vehicle quickly installs the lifting rescue platform 2 on top of the vehicle body 1 by adjusting the deployment angle of the support rod 9 and the telescopic rod 11. Firefighters stand on the rescue platform 8, which is raised to the required height by adding more support rods 9 and telescopic rods 11. Water, foam, and dry powder extinguishing agents from the fire equipment 3 are used to suppress the fire through high-pressure spray from the pressurized water outlet device 18. Simultaneously, the fire-fighting multi-functional drone 5 uses its drone gripper 31 to grab the rescue sleeve 6 and fly to the trapped floor. Using the double-helix nail gun nozzle 28, it fires adhesive-coated threaded nails 46 into the wall to form a composite anchoring layer, securing the rescue sleeve fixing plate 32. The trapped personnel enter the sleeve 33 and finally land safely on the main panel 22 and secondary panel 23 of the rescue air cushion system 4, with the wire mesh 25 preventing slippage and displacement.

[0084] Scenario 2: A multi-functional fire rescue vehicle, targeting a child trapped on a fourth-floor window sill, deploys a rescue air cushion system 4: the main panel 22 and the secondary panel 23 move and lay flat along slide rails A56 and B57; after the telescopic support rod 24 is deployed, nitrogen is used to eliminate the slide rail seams, forming a flat buffer surface; the wire mesh 25 encloses the protective area with rescue bollards 21. Firefighters operate a multi-functional fire-fighting drone 5 to fly to the window; the drone's gripper 31 grabs a rescue sleeve 6 and flies it to the trapped floor, simultaneously securing the rescue sleeve to the rescue air cushion system 4 from below.

[0085] Scenario 3: A lightweight protective and drone-assisted fire rescue vehicle is used in a chemical plant pipeline leak and explosion scenario. The fire tank 16 is injected with chemical inhibitors through the skylight structure 15, and the fire extinguishing medium is sprayed through the pressurized water outlet device 18 to suppress the fire.

[0086] Scenario 4: A lightweight protective fire rescue vehicle with drone assistance is designed for accidents such as vehicles falling off cliffs. If it is inconvenient to tie rescue ropes from above, a multi-functional fire-fighting drone 5 can carry a rescue sleeve 6 to the cliff location. The drone determines whether the rescue sleeve 6 is long enough to reach the bottom of the cliff. If so, the drone's gripper 31 anchors the sleeve fixing plate 32 to the rock mass using threaded nails 46. Firefighters can then jump into the sleeve 33 and quickly reach the bottom of the cliff to conduct the rescue.

[0087] The above scenario is just an example. In actual operation, there may be more modes, which can be operated by firefighters based on the situation on site.
