Description

Technical Field

[0001] The present invention belongs to the field of fire protection technology, and in particular relates to a new energy vehicle fire disposal and transportation device and method. Background Art

[0002] New energy vehicles play an increasingly important role in urban transportation networks. New energy vehicles parked in urban underground garages, charging stations, large parking lots and other places have brought new safety challenges. Underground garages, as an important part of urban underground space, have the structural characteristics of being closed, poorly ventilated, and having limited evacuation channels. In addition, factors such as dense parking of vehicles and complex pipelines make it difficult to evacuate and rescue people in the event of a fire. The consequences are often very serious. At the same time, due to the high energy density and chemical reactivity of the battery packs of new energy vehicles, they are prone to thermal runaway under abnormal conditions such as charging and collision, causing battery combustion or even explosion. The re-ignition rate is high, the spread speed is fast, and a lot of toxic gases are released, making it difficult for firefighters to deal with them quickly.

[0003] When a fire occurs, quickly transporting the burning new energy vehicle and moving it to an open area is an effective way to prevent it from igniting surrounding vehicles and reduce secondary hazards. Therefore, there is an urgent need to develop disposal and transport equipment suitable for new energy vehicle fires to improve the disposal efficiency when an accident occurs and reduce the loss of life and property.

[0049] Each water mist nozzle 6 is correspondingly provided with an infrared sensor for monitoring the temperature above the water mist nozzle 6 .

[0050] Infrared sensors are provided on the four side walls of the vehicle body 1.

[0051] In some embodiments, the lifting assembly 11 is an electric cylinder, the housing of the electric cylinder is fixedly connected to the vehicle body 1 , and the output shaft of the electric cylinder is fixedly connected to the lifting plate 10 .

[0052] In other embodiments, the lifting assembly 11 includes: a driving rod 1101, a bottom rod 1102, and a cross rod assembly. The cross rod assembly includes two cross-arranged support rods, namely a first support rod 1104 and a second support rod 1103. The middle of the first support rod 1104 and the second support rod 1103 is hinged by a hinge rod. The lower end of the first support rod 1104 is hinged to the bottom rod 1102, the upper end of the first support rod 1104 is hinged to the upper rod 1109, the lower end of the second support rod 1103 is hinged to the driving rod 1101, and the upper end of the second support rod 1103 is hinged to the lifting plate 10; the driving rod 1101 is correspondingly provided with a motor 1106, and the motor 110 6 is fixedly connected to the vehicle body 1, and a lead screw 1108 is fixedly arranged on the output shaft of the motor 1106, and a nut 1105 matching the lead screw 1108 is fixedly arranged on the driving rod 1101, and the lead screw 1108 and the nut 1105 are installed in coordination, and the lead screw 1108 is arranged along the length direction of the bottom rod 1102; side plates are fixedly arranged on both sides of the lifting plate 10, and a first strip through hole 1001 arranged along the axis of the lead screw 1108 is opened on the side plate, and the upper rod 1109 is installed on the inner side of the first strip through hole 1001; a second strip through hole 1107 arranged along the axis of the lead screw 1108 is opened on the bottom rod 1102, and the driving rod 1101 is installed on the inner side of the first strip through hole 1001.

The drive rod 1101 slides within the first strip-shaped through hole 1001, and the upper rod 1109 slides within the first strip-shaped through hole 1001, completing the lifting and lowering action of the lifting plate 10.

[0053] like Figure 6 As shown, a new energy vehicle fire disposal and transportation method includes the following steps:

[0054] S1. Move to the designated location according to the fire alarm location;

[0055] S2. Match the high-temperature location detected by the infrared sensor on vehicle body 1 with the built-in parking map and move to the bottom of the vehicle where the fire occurs;

[0056] The high-temperature location detected by the infrared sensor is matched with the built-in parking map to determine the exact coordinates of the parking space. The camera identifies the specific location of the vehicle where the fire occurred, making it easier for the device to move to the bottom of the vehicle where the fire occurred.

[0057] Infrared sensors monitor temperature changes in the parking lot in real time, detecting high-temperature areas around the vehicle on fire. Once abnormally high temperatures are detected, the system records the location of the area and matches it with a built-in parking map. The parking map contains the specific coordinates of each parking space in the parking lot. The system uses this data to match the high-temperature locations reported by the infrared sensors to determine the exact coordinates of the vehicle on fire. This ensures that after a fire occurs, the equipment can quickly locate and move to the bottom of the burning vehicle for treatment.

[0058] In addition to infrared sensors, the camera further determines the specific location of the fire vehicle through image recognition technology. The camera can identify license plates, body features or other vehicle identifications to help the system lock the fire vehicle more accurately.

[0059] The real-time image from the camera can assist the navigation system in precise positioning. Through the feedback from the visual system, the device can make fine adjustments to ensure that the positioning does not deviate, thereby moving quickly and accurately to the bottom of the vehicle where the fire occurs.

[0060] In addition, the device is equipped with an obstacle avoidance algorithm that can avoid moving vehicles and pedestrians, as well as vehicles that are not parked in parking spaces.

[0061] S3, raising the lifting plate 10 to lift the vehicle on fire, starting the water pump to spray fine water mist to the bottom of the car to cool it down;

[0062] Infrared sensors monitor the temperature distribution under the vehicle in real time. They precisely detect temperature changes and generate a temperature distribution map. By pinpointing the exact location of the heat source, the system can implement more targeted firefighting operations.

[0063] The temperature distribution map of the branch is divided into slices according to the fine water mist nozzle 6, the temperature of each slice is calculated, and the temperature threshold of the slice is set. When the temperature is lower than 50℃, the flow control valve does not open. When the temperature threshold of the slice is not lower than 50℃, the flow control valve opening is adjusted according to the temperature. The higher the temperature, the larger the opening of the flow control valve. In addition, the temperature rise curve can also be calculated. The greater the slope of the rise curve, the greater the valve opening.

[0064] If the infrared sensor detects that the temperature in a certain area of the fire vehicle is very high, the system will automatically increase the amount of fine water mist sprayed in that area to quickly reduce the temperature and suppress the fire source.

[0065] For areas with lower temperatures or non-fire sources, the flow regulating valve will reduce the amount of water mist sprayed, thereby preventing excessive water mist from affecting other parts and improving the efficiency of water mist use.

[0066] When the temperature at the fire source rises sharply, the flow regulating valve will increase the injection flow more quickly to ensure the timeliness and accuracy of the fire extinguishing process.

[0067] S4. Move the vehicle on fire to a safe area. The safe area can be an open area.

[0068] In step S3, the temperature of the vehicle on fire is monitored by the infrared sensor corresponding to the fine water mist nozzle 6, and the opening of the flow control valve is adjusted according to the temperature distribution of the vehicle on fire.

[0069] In S1, the vehicle can be moved to a designated location based on the alarm location, or an automatic patrol path can be set according to a map of the parking lot. During the patrol, the infrared sensor on the vehicle body 1 is used to monitor whether a fire has occurred, and a fire alarm is issued when a fire has occurred.

[0070] S11. Collect map data in the parking lot, calibrate the initial position of the device, and walk around the entire parking lot using inertial navigation to generate an accurate navigation map.

[0071] Map data collection:

[0072] Use sensors (such as lidar, visual sensors, GPS, inertial measurement units, etc.) to collect parking lot environmental data. These sensors can provide spatial information about the parking lot, including the locations of key facilities such as lanes, parking spaces, and charging stations.

[0073] During the acquisition process, the position is adjusted in real time based on inertial navigation (such as gyroscopes and accelerometers) to ensure that the device can obtain accurate position data when walking in the parking lot.

[0074] Generate a navigation map:

[0075] Inertial Navigation Technology: Using an Inertial Navigation System (INS) combined with real-time sensor data, the system can calculate the device's real-time location within the parking lot, eliminating issues with insufficient GPS signals or interference areas, ensuring the generated map is accurate.

[0076] Based on the equipment's travel path and the data collected, an accurate digital map of the parking lot is constructed, including the location information of each parking space, aisle and key facilities. Through this map, the equipment can better plan routes and identify locations.

[0077] S12. Use coverage algorithm to set automatic patrol path, reduce repeated paths, and increase coverage weight coefficient for locations with fixed charging piles.

[0078] Use coverage algorithms (such as ant colony algorithms, genetic algorithms, etc.) to ensure that the patrol path can cover the entire parking lot and try to avoid path duplication and redundancy. The goal of the algorithm is to maximize path coverage while minimizing patrol time and resource consumption.

[0079] The coverage algorithm takes into account the driving trajectory of the patrol equipment and dynamically adjusts the patrol path to avoid repeated walking in areas that have already been patrolled, thereby improving patrol efficiency.

[0080] Charging pile coverage weight coefficient:

[0081] Key Area Identification: For high-risk or critical facilities, such as charging stations in parking lots, their weight in route planning should be increased. Charging station areas are often where new energy vehicles are parked in large numbers, and pose a high risk of safety hazards such as battery fires. Therefore, patrol frequency must be increased.

[0082] Adjust the patrol priority of charging piles according to the preset weight coefficient to ensure that patrol equipment frequently passes through these important areas during patrols, and strengthen temperature monitoring and safety inspections around charging piles.

[0083] When using the coverage algorithm, not only the coverage and priority areas of the path are considered, but also the "path optimization" strategy is added. For example, the path in the charging pile area should be more precise and frequent, while other less important areas can reduce the number of patrols or extend the patrol cycle.

[0084] Beneficial effects:

[0085] By matching infrared sensors with parking space maps, supplemented by camera image recognition, the location of the fire vehicle can be accurately located, allowing the device to quickly move to the target area for disposal.

[0086] The built-in obstacle avoidance algorithm combines laser, infrared and camera data to enable the device to avoid pedestrians, moving vehicles and parked vehicles during movement, greatly improving operational safety and efficiency.

[0087] Based on the real-time feedback of the temperature distribution map under the fire vehicle, the water mist spray flow rate is adjusted through the flow control valve to achieve targeted cooling, ensuring that the fire extinguishing process is rapid and accurate, reducing water waste and strengthening fire source control.

[0088] The device is equipped with a complete map collection and navigation system, which covers the entire area through automatic patrol routes. It can not only proactively detect fire risks, but also respond quickly after a fire occurs.

[0089] The new energy vehicle fire handling and transportation device of the present invention integrates the vehicle body structure, lifting mechanism, and fine water mist fire extinguishing to achieve automated management of the entire process of fire vehicles, from initial detection and precise positioning to emergency handling and safe transportation. This method not only ensures rapid and accurate arrival at the fire source area when a fire occurs, but also achieves rapid cooling by intelligently adjusting the water mist spray volume. It also ensures the safety of the entire handling process through an obstacle avoidance algorithm. Automatic patrol and map-building functions enable the device to achieve all-weather monitoring and immediate response in complex parking environments, greatly improving the efficiency and safety of handling new energy vehicle fires.

[0090] After a vehicle fire occurs, the device moves to the bottom of the vehicle and cools the bottom of the vehicle by spraying fine water mist, while moving the vehicle to a designated location, thereby improving the efficiency of fire handling in the parking lot.
