Description

Technical Field

[0001] The present invention relates to the field of firefighting and rescue technology, and in particular to a fire truck carrying a drone and a method for using the same. Background Art

[0002] When a fire occurs in a building of average height, traditional fire trucks typically deploy aerial ladders to break windows and extinguish fires. The specific process is as follows: the fire truck first extends the aerial ladder to the burning floor. Firefighters use the ladder to approach the building and break windows, thereby creating a firefighting route into the fire scene. Firefighters then use the fire sprinklers mounted on the ladder to spray fire extinguishing agents into the fire scene, thereby extinguishing the fire. However, there are significant limitations on the height at which aerial ladders can be deployed. With the advancement of engineering technology, the height of super-high-rise buildings has far exceeded the limits of traditional aerial ladder fire trucks. Once a fire occurs in a super-high-rise building, the aerial ladders of traditional fire trucks simply cannot reach the effective height, making it difficult for them to approach the fire scene to break windows and extinguish the fire.

[0003] To overcome the height limitations of traditional fire truck ladders, existing technologies have introduced the use of drones for firefighting. This approach involves controlling a drone to launch projectiles to break windows, followed by the use of a mounted fire hose to spray fire extinguishing agent into the fire. However, this approach has significant drawbacks: drones must maintain a stable attitude during flight. Excessive recoil from projectiles can cause the drone to shake violently, lose control of its flight trajectory, or even crash. To ensure drone flight safety, the projectile's mass and launch speed must be limited, resulting in insufficient destructive power. Modern high-rise buildings, in particular, commonly utilize explosion-proof glass to meet safety, thermal, and soundproofing requirements. The low-powered projectiles launched by existing drones are unable to effectively penetrate this glass, making it impossible to open firefighting routes.

[0004] Furthermore, even if a window is successfully broken, the drone's limited payload capacity means the diameter of the fire hose it carries is small, limiting the amount of water it can deliver. In the face of a large-scale fire, a small flow of water is unable to quickly cover the fire source and effectively cool it, making it impossible to control the spread of the fire in a timely manner. Its effectiveness is insufficient for firefighting in super-high-rise buildings. Summary of the Invention

[0009] Preferably, a water wheel linked to the impact head is provided in the recoil flow channel, and the water wheel can drive the impact head to rotate around its axis under the action of the water flow in the recoil flow channel. The outer wall of the impact head has multiple edges evenly distributed along the circumference, and the edges extend along the axial direction of the impact head.

[0010] Preferably, the tip of the impact head is connected to an injection channel, and the injection channel is connected to a water storage chamber through a guide channel. A valve core capable of opening or closing the guide channel is provided at the guide channel; the valve core can move to a position where the guide channel is opened under the action of inertia, and the valve core is connected to a reset component, and the reset component has a tendency to drive the valve core to move to a position where the guide channel is closed; a first extrusion block is sealingly and slidingly connected in the water storage chamber, and the first extrusion block is connected to a first elastic member.

[0011] Preferably, the reset assembly includes a valve chamber and a control chamber filled with actuating fluid, a first flow channel and a second flow channel are connected between the valve chamber and the control chamber, the valve core is sealingly and slidingly connected to the valve chamber, a second extrusion block is sealingly and slidingly connected in the control chamber, and the second extrusion block is connected to a second elastic member.

[0012] Preferably, a check valve is provided in the first flow passage, and the check valve is used to limit the actuating fluid from flowing from the control chamber into the valve chamber through the first flow passage.

[0013] Preferably, the impact hammer includes a hammer seat and a striker rod slidably connected to the hammer seat, and the striker rod can move relatively away from the hammer seat in a direction close to the building under the action of inertia.

[0014] Preferably, a first position and a second position are sequentially provided on the movement trajectory of the impact rod relatively away from the hammer seat in the direction away from the hammer seat; a diversion cavity connected to a fire hose is provided on the hammer seat; the fire extinguishing flow channel is provided in the impact rod, and a first flow hole connected to the fire extinguishing flow channel is opened on the side wall of the impact rod, and a blocking wall cooperating with the first flow hole is provided on the hammer seat; the recoil flow channel is provided between the impact rod and the hammer seat, a second flow hole is provided between the diversion cavity and the recoil flow channel, and a blocking ring cooperating with the second flow hole is provided on the impact rod; when the impact rod is in the first position, the first flow hole is aligned with the blocking wall, and the second flow hole is staggered with the blocking ring; when the impact rod is in the second position, the first flow hole is staggered with the blocking wall, and the second flow hole is aligned with the blocking ring.

[0015] Preferably, the outer diameter of the blocking ring is loosely matched with the inner diameter of the recoil flow channel, and a plurality of ribs are evenly distributed circumferentially between the impact rod and the blocking ring, and the ribs extend axially along the recoil flow channel.

[0016] The present invention also provides a method for using the fire truck carrying the drone, comprising the following steps:

[0017] S1. Wind the first cable around the rotating member and control the drone to install the support member on the building;

[0018] S2. Control the first hoisting device to operate, causing it to lift the impact hammer connected to the fire hose and the second cable to a designated position on the building through the first cable;

[0019] S3, controlling the operation of the second hoisting device to drive the hammer to swing back and forth around the rotating member toward or away from the building through the second cable, so that the hammer strikes the outer protective structure of the building at a designated position back and forth;

[0020] S4. After the impact hammer penetrates the outer protective structure at the designated position of the building, the water supply system is controlled to transport the fire extinguishing agent into the building through the fire hose and the fire extinguishing flow channel in sequence.

[0021] The beneficial effects of the present invention are:

[0022] When carrying out firefighting operations, the present invention first winds the first cable around the rotating part of the support, and then controls the drone to set up the support on the burning building. Afterwards, by controlling the first hoisting device, the first cable is used to lift the striker connected to the fire hose and the second cable to a designated position on the building - that is, the location of the fire. Compared with the traditional method of directly mounting a fire hose on a drone, the present invention gets rid of the limitation of the drone's mounting capacity - the drone of the present invention only needs to undertake the task of setting up the support. After the support is set up, the weight of the striker, fire hose and second cable that can be lifted depends on the strength of the first cable. In this way, it is possible to lift a heavier striker and a larger diameter fire hose to the location of the fire.

[0023] After the first winch device raises the hammer to a designated position via a first cable, the second winch device is controlled, and the second cable is used to drive the hammer to swing back and forth around the rotating member, toward and away from the building, causing the hammer to strike the surrounding protective structure at the fire scene. Compared to the method of breaking windows by launching projectiles from a drone, the movement of the hammer of the present invention is not affected by the drone's flight safety. The heavier hammer can penetrate the building's explosion-proof glass with greater force, thereby opening a fire-fighting route into the fire scene.

[0024] After the fire extinguishing channel is opened, the water supply system is controlled to transport the fire extinguishing agent into the building through the fire hose and the fire extinguishing flow channel in sequence to carry out fire extinguishing operations.

[0025] The present invention can effectively open the fire extinguishing channel, cover the fire source with a large flow of water and effectively reduce the temperature, thereby meeting the fire extinguishing needs of super high-rise buildings. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. In order to better illustrate this embodiment, certain components of the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent the actual size of the product.

[0048] It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0049] Example 1

[0050] See also Figure 1 and Figure 2 The present invention provides a fire truck carrying a drone, including a vehicle body 100 and a drone 111 mounted on the vehicle body 100.

[0051] The drone 111 is provided with a support 112, which is used to be mounted on a window sill, balcony, or other building structure after reaching the target floor, forming a stable operating fulcrum. A rotating member 113 (such as a pulley or universal joint) is provided on the support 112, and a first cable 114 is wound around the rotating member 113.

[0052] The striking hammer 200 is connected to the first hoisting device 115 on the vehicle body through the first cable 114. The first hoisting device 115 is used to control the retraction and extension of the first cable 114, so as to vertically lift or lower the striking hammer 200 to a designated position on the building. The striking hammer 200 is also connected to the second hoisting device 117 on the vehicle body through the second cable 116. The second hoisting device 117 reels in the second cable 116, which can pull the striking hammer 200 away from the building. Subsequently, when the second hoisting device 117 releases the second cable 116, the striking hammer 200 swings toward the building like a pendulum under the action of gravity, causing an impact. By repeatedly operating the second hoisting device 117, the striking hammer 200 can achieve a reciprocating swinging impact on the building's outer protective structure (such as a glass curtain wall or a brick wall).

[0053] The front end of the hammer 200 is a tapered impact head 203, which houses a fire-extinguishing flow channel 205. This flow channel is connected to the fire truck's water supply system via a fire hose 118. Once the hammer 200 successfully breaches the building's exterior wall, the water supply system activates, spraying a fire extinguishing agent such as water or foam directly into the building through the fire hose 118 and the fire-extinguishing flow channel 205, effectively extinguishing the fire.

[0054] When conducting firefighting operations, firefighters first wind the first cable 114 around the rotating member 113 of the support member 112. At this point, the first end of the first cable 114 is connected to the impact hammer 200 placed on the ground, and the second end of the first cable 114 is connected to the first hoisting device 115. Next, the firefighter controls the flight of the drone 111 and the first hoisting device 115 to release the first cable 114 during the flight of the drone 111. Finally, the drone 111 is used to set the support member 112 on the burning building. Throughout the flight, the drone 111 only bears the weight of the support member 112 and the first cable 114.

[0055] After the support member 112 is erected, firefighters control the first hoisting device 115 to reel in the first cable 114, thereby lifting the striker 200, which is connected to the fire hose 118 and the second cable 116, to the fire scene. It should be noted that the first cable 114 of this embodiment is a strong, lightweight composite rope, which can lift the heavy striker 200 and the large-diameter fire hose 118 to the fire scene.

[0056] After the first hoisting device 115 raises the striker 200 to the designated position via the first cable 114, firefighters control the second hoisting device 117 and, using the second cable 116, drive the striker 200 to swing back and forth around the rotating member 113, toward and away from the building. This allows the striker 200 to strike the surrounding fire structure. The heavy striker 200's powerful impact can penetrate the building's explosion-proof glass, opening a fire escape route into the fire.

[0057] After the fire extinguishing passage is opened, the fire fighters control the water supply system to transport the fire extinguishing agent into the building through the fire hose 118 and the fire extinguishing flow channel 205 in sequence to carry out the fire extinguishing operation.

[0058] In this embodiment, the support member 112 is an F-shaped structure, which can be clamped on the wall at the top of the building. The rotating member 113 is a roller rotatably connected to the support member 112.

[0059] It is understood that the first hoisting device 115 and the second hoisting device 117 in this embodiment are both arranged on the vehicle body. Of course, in other embodiments, the first hoisting device 115 and the second hoisting device 117 can also be directly mounted on the ground.

[0060] It should be noted that in this embodiment, the water supply system is the water supply system of the fire truck. Since the specific structure of such a water supply system is well known to those skilled in the art, this specification does not describe it in detail, but this does not affect those skilled in the art's understanding and implementation of the technical solutions involved in this specification.

[0061] Example 2

[0062] On the basis of the first embodiment, in order to further increase the impact speed, the impact hammer 200 is optimized in this embodiment.

[0063] See also Figure 5 , a recoil flow channel 206 is added to the impact hammer 200, which is also connected to the fire hose 118, but its nozzle is facing opposite to the impact direction (i.e., away from the building). When the water supply system is working, the water flow ejected from the recoil flow channel 206 will generate a backward thrust. According to Newton's third law, the impact hammer 200 will obtain a reaction force of equal magnitude and forward direction. This reaction force will be effectively superimposed on the forward kinetic energy of the impact hammer 200 itself, so that it obtains a higher instantaneous speed when it contacts a building or obstacle. As a result, the impact hammer 200 can hit the target at a faster speed and with stronger kinetic energy, thereby greatly improving its demolition efficiency and penetration, especially when facing solid walls, windows or obstacles, it can open rescue channels or perform smoke exhaust operations more quickly.

[0064] Example 3

[0065] Existing high-rise buildings often use explosion-proof glass on their exterior walls. This glass is typically composed of multiple layers of glass, which provide more than just thickness. When a spike impacts explosion-proof glass, the energy is transferred layer by layer. The first layer of glass will suffer local damage upon impact, but the energy is dispersed and transferred to the next layer of glass and the polymer interlayer. Unlike the brittle nature of glass, polymer interlayers composed of materials such as PVB and SGP possess exceptional toughness and elasticity. When impacted by a spike, they absorb significant impact energy and deform rather than breaking immediately. This elastic deformation effectively prolongs the impact, reducing transient stress and, therefore, minimizing the likelihood of spike penetration.

[0066] In order to cope with the high-toughness materials in explosion-proof glass, the impact head 203 is specially designed in this embodiment.

[0067] See also Figure 4 and Figure 5 A water wheel 207 is installed within the recoil channel 206. Water flowing through the recoil channel 206 drives the water wheel 207 to rotate. This, in turn, works in conjunction with the impact head 203, driving the impact head 203 to rotate at high speed around its own axis. Furthermore, the outer wall of the impact head 203 is evenly distributed along its circumference, with multiple edge blades 204 evenly distributed along its circumference.

[0068] When the impact head 203 with the sharp edge 204 strikes the explosion-proof glass, due to its own rotation, the impact force is no longer unidirectional, but is accompanied by a high-speed cutting and tearing action. This unique rotational tearing action can effectively cut into and tear the polymer interlayer inside the explosion-proof glass. The tearing action pulls the interlayer material outward, causing the material to fail ductilely. Although the viscoelastic polymer interlayer can absorb energy and deform, under the action of continuous tearing force, it will exceed its elastic limit, undergo plastic deformation, and eventually break. This causes it to quickly lose its integrity, thereby destroying its structure more quickly and thoroughly.

[0069] In addition, the high-speed rotation of the impact head 203 and the water wheel 207 produces a powerful gyroscopic effect. When the impact head 203 and the water wheel 207 rotate at high speed, they tend to maintain the direction of their rotation axis unchanged. This enhances the stability of the posture during the impact process. The stable posture ensures that the motion trajectory of the impact head 203 before contacting the target is closer to a straight line, reducing unnecessary deviations. Due to its rotation, even when encountering air resistance, the swing trajectory can be kept stable. Furthermore, the stability maintained by the gyroscopic effect ensures that the vast majority of kinetic energy is converted into an effective impact perpendicular to the target surface, making the impact energy more concentrated, thereby achieving higher destructive efficiency in a single impact.

[0070] Example 4

[0071] In order to further enhance the damage effect on structures such as glass or walls, this embodiment introduces a "water wedge" effect mechanism.

[0072] The tip of the impact head 203 is connected to an injection channel 208. The channel is connected to a water storage chamber 210 through a guide channel 209. The first extrusion block 212 and the first elastic member 213 are sealed and slidably provided inside the water storage chamber 210. The guide channel 209 is provided with a valve core 211 that can be opened under the action of inertia.

[0073] When the hammer 200 strikes the target at high speed, the immense inertial force instantly drives the valve core 211 forward, overcoming the resistance of the reset assembly 300 and opening the flow channel 209. At this point, water within the water storage chamber 210, under the pressure of the first extrusion block 212 and the first elastic member 213, is ejected at high speed from the tip of the impact head 203 through the injection channel 208, injecting into the tiny cracks created by the collision. Because water is an incompressible fluid, when squeezed into these cracks under high pressure, it creates a massive "water wedge" effect, rapidly expanding and deepening the initial cracks and significantly increasing the destructive power to the target structure.

[0074] To achieve precise control of the water wedge effect, the reset assembly 300 is designed as a hydraulic damping structure. It includes a valve chamber 301 filled with actuating fluid and a control chamber 302. The valve core 211 slides within the valve chamber 301, and the control chamber 302 contains a second extrusion block 305 and a second elastic member 306. The two chambers are connected by a first flow channel 303 with a check valve 307 and a second flow channel 304 without a valve. During an impact, the valve core 211 moves forward, and the actuating fluid quickly flows from the valve chamber 301 into the control chamber 302 through the first flow channel 303 and the second flow channel 304, achieving rapid valve opening. After the impact, the second elastic member 306 pushes the second extrusion block 305, and the actuating fluid can only slowly flow back to the valve chamber 301 through the narrower second flow channel 304, thereby exerting a slow reset force on the valve core 211, causing it to slowly reset. This "quick opening and slow closing" feature ensures that water can continue to flow in a short period of time after the impact, allowing the water wedge effect to be fully developed and improving the thoroughness of the demolition.

[0075] Example 5

[0076] In order to further enhance the impact effect and the coherent switching of the water jet direction, this embodiment has been further improved.

[0077] The hammer 200 comprises a hammer base 201 and a striking rod 202 that slides along its axis. The front end of the striking rod 202 is the striking head 203. As the hammer 200 swings toward a building, when the hammer base 201 suddenly decelerates due to contact, the striking rod 202 continues to slide forward due to its own inertia. This inertial energization effect gives the striking rod 202 a higher relative velocity than the hammer base 201 at the moment of contact, resulting in the striking rod 202 impacting the target with greater kinetic energy.

[0078] The relative sliding of the impact rod 202 can realize the automatic switching of the direction of water flow. A diversion chamber 400 is provided on the hammer seat 201, which is connected to the fire hose 118. When the impact rod 202 is in the initial first position (before impact or in the early stage of impact), the first flow hole 401 thereon (connected to the fire extinguishing flow channel 205 in front) is closed by the blocking wall 402 on the hammer seat 201; and the second flow hole 403 on the hammer seat 201 (connected to the recoil flow channel 206 in the rear) is open. At this time, the water flow is mainly used for recoil acceleration. When the impact rod 202 moves forward to the second position under the action of inertia (after complete impact and penetration), its position changes: the first flow hole 401 is offset from the blocking wall 402 and opened, and the fire extinguishing flow channel 205 is connected; at the same time, the blocking ring 404 on the impact rod 202 aligns with and closes the second flow hole 403, and the recoil flow channel 206 is closed.

[0079] This switching mechanism ensures that energy is used for recoil acceleration during the impact phase, and automatically switches to forward jetting for fire extinguishing after demolition is completed, achieving seamless connection of rescue operations and greatly improving water utilization efficiency and rescue continuity.

[0080] Example 6

[0081] To further optimize the efficiency of the water wheel 207, a plurality of axially extending ribs 405 can be provided within the recoil channel 206, upstream of the water wheel 207. These ribs 405 straighten the water flow, allowing it to strike the blades of the water wheel 207 more smoothly and directionally, thereby improving energy conversion efficiency and enabling the impact head 203 to achieve higher rotational speeds and torque.

[0082] The method of use provided by the present invention specifically comprises the following steps:

[0083] S1. After the fire truck arrives at the fire scene, the fire commander quickly conducts a fire investigation. Based on the fire investigation results, a specific firefighting plan is developed. This plan covers the location of the windows to be broken, the flight path of the drone 111, and the lifting and swinging trajectory of the hammer 200. According to the firefighting plan, firefighters first wrap the first cable 114 around the rotating member, then control the drone 111 to set up the support member 112 on the building.

[0084] S2: After the support member 112 is erected, the firefighter controls the first hoisting device 115 to operate. The first hoisting device 115 uses the first cable 114 to lift the striker 200 connected to the fire hose 118 and the second cable 116 to a designated position on the building.

[0085] S3. After the hammer 200 reaches the designated location, the firefighter activates the second hoisting device 117. The second hoisting device 117, via the second cable 116, drives the hammer 200 to swing back and forth around the rotating member 113, toward and away from the building. This causes the hammer 200 to strike the building's exterior at the designated location. During this process, the firefighter controls the water supply system to deliver high-pressure water to the fire hose.

[0086] If the explosion-proof glass is not penetrated, the high-pressure water flow enters the recoil channel 206. The water flow ejected from the recoil channel 206 generates a backward thrust, simultaneously driving the water wheel 207 to rotate. This not only helps maintain the stability of the striker 200, ensuring that the central axis of the striker 200 remains as perpendicular to the plane of the glass as possible upon contact; but also, when the impact head 203 cuts into the explosion-proof glass, the water wheel 207 drives the impact head 203 to rotate at high speed around its own axis, causing the edge 204 on the impact head 203 to tear the polymer interlayer inside the explosion-proof glass, thereby destroying the explosion-proof glass.

[0087] Furthermore, a portion of the high-pressure water flows through the first branch pipe into the water storage chamber 210, compressing the first elastic member 213. When the impact head strikes the explosion-proof glass, the inertia generated by the impact causes the valve core 211 to move forward, and the actuating fluid rapidly flows from the valve chamber 301 into the control chamber 302 through the first flow passage 303, thereby opening the flow guide 209. At this point, under the pressure of the first extrusion block 212 and the first elastic member 213, the water in the water storage chamber 210 is ejected at high speed from the tip of the impact head 203 through the flow guide 209 and the injection channel 208, precisely striking the collision point and assisting the impact hammer 200 in breaking the window using the water wedge effect.

[0088] S4. After the hammer 200 penetrates the building's outer protective structure at a designated location, the hammer base 201 suddenly decelerates due to the obstruction of the unpenetrated portion of the explosion-proof glass. At this point, the striker rod 202 continues to slide forward under its own inertia, moving from the first position to the second position, thereby closing the recoil channel 206 and opening the fire extinguishing channel 205. This controls the water supply system, delivering the fire extinguishing agent sequentially through the fire hose 118 and the fire extinguishing channel 205 into the building.
