Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to an intelligent fire truck that assists in fire fighting of new energy vehicles. Background Technology

[0002] With the continuous development of the new energy vehicle market and its rapid increase in market share, the unique fire safety risks of new energy vehicles are becoming increasingly prominent, especially in enclosed and densely populated places such as underground parking garages in shopping malls. When the core lithium-ion battery in the power system of new energy vehicles experiences "thermal runaway" due to collisions, short circuits, or other reasons, it can cause violent combustion, produce a large amount of toxic and high-temperature smoke, and even explode. It can ignite surrounding vehicles in a very short time, causing huge losses of life and property.

[0003] Currently, the traditional firefighting method for new energy vehicle fires in underground parking garages is as follows: firefighters need to risk their lives at close range to first set up fireproof boards around the burning vehicle to prevent the fire from spreading, and then use long-distance water spraying to extinguish the fire. This requires the cooperation of multiple firefighters, using fire blankets to manually cover and wrap the vehicle body, and even using AGV carts to lift the mobile fire source of the burning vehicle to an open space. However, this method has significant drawbacks such as high personnel safety risks, slow response speed, low efficiency, and large property losses. In existing technologies, there are also preliminary fire extinguishing solutions for the emergency deployment of fire blankets after a new energy vehicle catches fire. For example, application number CN202521122826.5 discloses a device for quickly covering a new energy vehicle with a fire blanket. This device involves pulling the fire blanket outward, causing the fire blanket to rotate a shaft, thereby pulling the fire blanket out of the housing. Simultaneously, during the pulling process, two pull ropes are moved in opposite directions, causing the fire blanket to automatically unfold during the pull. Because the fire blanket is pre-wound onto the shaft, the unfolding process is rapid and even. The fire blanket is evenly distributed and can quickly cover the fire source to extinguish it. During the rolling process, the curved support plate and the fire blanket abut against each other, allowing the fire blanket to be tightly rolled onto the shaft, preventing it from becoming loose. As the fire blanket rolls up, the diameter of the resulting cylinder gradually increases. Due to the spring mechanism, when the gradually increasing cylinder of the fire blanket presses against the curved support plate, it causes the curved support plate to rotate. The rotation of the curved support plate causes the cylindrical cylinder to rotate, and the rotation of the cylindrical cylinder compresses the spring, ensuring that the curved support plate always abuts against the fire blanket. Furthermore, due to the installation at the rear end of the bottom of the housing... Equipped with two casters, the entire laying device can be moved by tilting the box backward. Foot pads installed at the front end and in the groove at the bottom of the box ensure that when the box is moved to the desired position and placed vertically, the foot pads contact the ground, preventing the box from moving when the fire blanket is pulled out to cover the fire source. Application number CN202410094144.1 discloses a rapid laying device for a fire blanket for new energy vehicles. A sensor detects a fire in the new energy vehicle and transmits a signal to a drag motor, which promptly lays the fire blanket onto the vehicle using fine steel... The fire blanket automatically and completely covers the car when the wire breaks and its own weight is applied, effectively solving the problem that traditional garage fire extinguishing devices cannot control the spread of fires from new energy vehicles to surrounding vehicles in a timely manner. It allows for rapid deployment; when the fire blanket is pulled out of the housing, it naturally droops due to gravity, reducing the pulling force required by the drag motor and facilitating rapid unfolding. At this point, the drag motor switches from slow to fast, enabling the fire blanket to be quickly laid to the vehicle. It is also easy to install on existing garage walls; the drag motor is mounted on the fire blanket housing, saving space and making it well-suited for existing garages.

[0004] These fire-extinguishing devices that assist in the installation of fire blankets have achieved a certain degree of automatic blanket deployment, but they still have the following common defects: Incomplete fire blanket coverage, often only covering the roof or one side of the vehicle, fails to achieve a complete seal around the entire vehicle body. This results in limited air isolation, failing to effectively suppress the continued combustion inside the battery and potentially causing reignition. Furthermore, gaps remain between the fire blanket and the ground or vehicle chassis, allowing outside air to enter and preventing the effective containment of high-temperature, toxic gases generated during internal combustion, posing a risk of secondary combustion and explosion. Existing fire blanket installations are mostly fixed or simple mobile types, lacking autonomous movement, precise positioning, and adaptability to different vehicle models in complex garage environments. They still require close-range personnel intervention and have low timeliness, limiting overall firefighting efficiency. Fixed installations are also too costly. Therefore, there is an urgent need for an intelligent fire truck to assist in firefighting of new energy vehicles, capable of autonomous navigation, rapid response, all-around coverage, and active sealing and isolation, to address the increasingly severe challenges posed by new energy vehicle fires.

[0015] This invention provides an intelligent fire truck that assists in firefighting of new energy vehicles, and has the following beneficial effects: 1. This intelligent fire truck assisting in firefighting of new energy vehicles features a lifting platform assembly and a multi-section telescopic arm assembly on its body. The lifting platform assembly raises the multi-section telescopic arm assembly to a position matching the height of the target vehicle's top. The telescopic arm then extends and retracts to unfold the fire blanket, covering the entire target vehicle. A rope release roller releases the steel wire rope, triggering a weightless guide hammer to clamp the fire blanket, which then hangs down under gravity, enveloping the target vehicle. A rope tightening device that can move up and down / back and forth retracts the steel wire rope within the edge of the fire blanket, ensuring the bottom edge is tightly secured to the ground, forming a near-sealed isolation space. This effectively isolates oxygen, suppresses open flames, and prevents the leakage of toxic gases, resulting in significant fire extinguishing and reignition prevention effects.

[0016] 2. This intelligent fire truck assisting in firefighting of new energy vehicles, through the setting of a balancing counterweight mechanism, innovatively linked with the telescopic boom, ensures that the entire vehicle remains stable even when the boom is extended significantly, preventing the risk of overturning.

The weightlessness-triggered guide hammer uses gravity to automatically and reliably release the fire blanket. The action is rapid and efficient. It also uses mechanical and hydraulic transmission methods to provide ample power, strong adaptability to high-temperature fire environments, high timeliness, and timely rescue efficiency.

[0018] 4. This intelligent fire truck assisting new energy vehicles in firefighting is equipped with an automatic driving remote control system, which automates the entire process from receiving the alarm, route planning, driving to firefighting operations. It completely isolates firefighters from the most dangerous fire center area, greatly ensuring personal safety, reducing property losses and narrowing the scope of the fire.

The automatic driving remote control method includes the following steps: Receiving fire signals from third parties to trigger firefighting missions and automatically driving to the target fire source: The intelligent fire truck that assists in firefighting of new energy vehicles is placed in a fixed parking space in the underground garage of the shopping mall and receives firefighting instructions from the fire control center platform of the shopping mall through the communication network; By combining the high-precision CAD map of the parking garage pre-recorded in the shopping mall, the real-time location of the fire and the location of the intelligent fire truck itself can be obtained; The intelligent fire truck is automatically driven to the target fire source. This is achieved by utilizing the sensing devices on the intelligent fire truck or configuring a communication module on it, and equipping a remote control station with a dual-joystick professional controller in the supermarket fire control center platform to remotely control the vehicle. For example, it can use LiDAR, visual cameras, inertial measurement units (IMUs) combined with wheel speed meters, and employ a fusion SLAM algorithm to fuse LiDAR and visual data. Based on the global path, it can perform real-time local path replanning to generate a smooth, safe, and executable local trajectory; or it can be manually controlled by a dual-joystick professional controller via 5G communication to move the intelligent fire truck to the target vehicle. Fire blankets are laid to carry out fire extinguishing operations: Fire extinguishing operations are carried out through laser radar and vision fusion or remote control, and graded action control is performed. The following steps include controlling the position of the vehicle body 1 of the intelligent fire truck, ensuring that the extension and retraction direction of the multi-section telescopic boom assembly 5 is consistent with the front and rear direction of the target vehicle, and braking and parking the vehicle after locating the work point. After parking, the second hydraulic power system 402 is activated to raise the top seat 403 of the lifting platform to a matching height equivalent to the roof of the target vehicle. Then, the hydraulic power system inside the fixed rail rod 303 and the third hydraulic power system 502 of the moving rail tube 302 are activated simultaneously, so that the moving rail tube 302 with built-in hydraulic power system moves back and forth on the fixed rail rod 303, thereby driving the counterweight 301 to move backward towards the rear of the vehicle, so that the counterweight 301 is stable as a whole. At the same time, the third hydraulic power system 502 drives the multi-section boom 501 to unfold. With the help of the second fixed pulley 507 and the steel wire rope inside the multi-section boom 501, the first section of the multi-section boom 501 extends the second section of the boom by means of the steel wire rope, and the second section extends the third section of the boom by means of the steel wire rope, so as to achieve the overall extension of the multi-section boom. The activated third hydraulic power system 502 drives the multi-section boom 501 to smoothly unfold towards the target vehicle, transporting the fire blanket 7 and unfolding it directly above the target vehicle. After reaching the predetermined position, the automatic driving remote control system issues a command to the gripper 6 to release the fire blanket 7. The electromagnetic lock 602 of the first gripper block 601 is de-energized and released, opening the gripper. At the same time, the motor of the control rope retraction roller 504 rotates, releasing the steel wire rope 508, so that the weightlessness trigger guide hammer 8 is driven by gravity to pull the fire blanket 7 to fall freely to the ground. When the gravity hammer 803 touches the ground, the weightlessness causes the internal mechanical compression of the pin 804 to cause one end to turn under the pressure of the gravity at the bottom of the double-ear hinge block 801, and the other end to automatically open the hook 805 and disengage from the fire blanket 7. After the gripper 6 and the weightlessness triggering guide hammer 8 are both disengaged from the fire blanket 7, the fourth hydraulic power system 904 and the first hydraulic power system 306 are activated respectively to move the vertical rod 916, the robotic arm 915, and the balance telescopic arm 304 in the up-down and forward-backward directions. This causes the bottom end of the vertical telescopic arm 905, which is connected to the positioning crossbar 902 and the second gripper block 903, to move up and down. The vertical rod 916 moves up and down within the sleeve 305, and the robotic arm 915 on the limiting block 906... The rope retractor 901 moves back and forth, thus realizing the three-dimensional spatial movement of the rope retractor 901. This determines whether the steel wire rope inside the fire blanket 7 needs to be retracted. When the rope tightening device 9 does not need to retract the rope, the rope retractor 901 is raised to avoid affecting the movement of the fire extinguishing vehicle. When the rope tightening device 9 needs to retract the rope, the rope retractor 912 can be moved to a position close to the vehicle and the ground, so that the fire blanket 7 can wrap the target vehicle more tightly, avoiding situations where the bottom of the vehicle is not covered, exposing a large part of the chassis space, which would affect the fire extinguishing effect. Start the hydraulic motor 914 to drive the shaft of the rope take-up device 912 to rotate, thereby powerfully retrieving the stainless steel wire rope pre-embedded in the edge of the fire blanket 7 until the tension of the stainless steel wire rope reaches the preset threshold, indicating that the fire blanket has tightly wrapped the vehicle body and formed an effective seal with the ground.

[0036] Post-fire extinguishing procedures: Given the effective sealing of the fire blanket 7, and based on the temperature, heat release, and toxic gas concentration emission standards in the area, if there is no possibility of reignition on the vehicle body within a predetermined time period, the vehicle will display a mission completion status after the fire is effectively controlled. After the rope retractor 912 tightens the steel wire rope inside the fire blanket 7, there will be an anti-reverse ratchet locking mechanism to ensure that it will not loosen after tightening. After the rope retractor 912 is tightened, it will separate from the rope retractor drive seat 911. The rope retractor 912 and the fire blanket 7 will remain in a tightened state, covering the burning target vehicle. The target vehicle wrapped with the fire blanket 7 will then be handled by firefighters, supermarket staff, and the vehicle owner. The intelligent fire truck without the fire blanket 7, after receiving the evacuation order from the command center, will automatically return to its original position along the original route. The staff in the supermarket can take out the spare fire blanket 7 from the intelligent fire truck and replace it on site. The fire blanket is then manually reinstalled on the rope retractor 912, the second gripper block 903, the gripper piece 6, and the weightlessness trigger guide hammer 8. The third hydraulic power system 502 will then drive the multi-section boom 501 to retract.
