In the “Emergency Mission 2021” earthquake relief exercise held on May 14, facing the raging flames, facing various dangerous and complex environments such as tall buildings, high temperature, dense smoke, toxic, hypoxia, etc., a large number of new technologies and equipment were unveiled. There are drone groups and the province’s first fire-fighting robot rescue team.
What role can they play in rescue?
Scene 1 Gasoline tank leaks, explosion occurs, fire-fighting robot rescue team appears
On May 14, after the simulated “strong earthquake”, the gasoline tank area (6 3000m storage tanks) of the Daxing storage tank area of Ya’an Yaneng Company leaked, forming a flow area of about 500m in the fire dike and caught fire, causing No. 2 in succession. , No. 4, No. 3 and No. 6 tanks exploded and burned, and the height of the flame sprayed out was tens of meters, and the fire was very violent. This explosion poses a serious threat to other storage tanks in the tank area, and the situation is extremely critical.
This is a scene from the main exercise field in Ya’an. Fighting side by side with firefighters in silver heat-insulated suits in the scorching fire scene is a group of “Mecha Warriors” in orange suits—the robot squadron of the Luzhou Fire Rescue Detachment. At the drill site, a total of 10 operators and 10 fire-fighting robots were extinguishing the fire.
I saw 10 fire-fighting robots ready to go to the designated point one after another, and quickly sprayed foam to cool the fire tank to extinguish the fire, and ensure the accuracy of the fire-extinguishing agent throughout the process and the efficient spraying, which effectively prevented the fire from spreading.
After the on-site headquarters adjusts the combat forces of all parties and initiates the fire-fighting command, all fire-fighting robots will show their “superior power”. Under the command of the commander, they can flexibly adjust the spray angle of the water cannon, increase the jet flow, and extinguish the fire by swinging left and right. The entire tank area was cooled and extinguished, and the fire was finally successfully extinguished.
The reporter learned that the firefighting robots participating in this exercise are RXR-MC40BD (S) medium foam fire extinguishing and reconnaissance robots (codenamed “Blizzard”) and 4 RXR-MC80BD firefighting and reconnaissance robots (codenamed “Water Dragon”). . Among them, the “Water Dragon” is equipped with a total of 14 units, and the “Blizzard” is equipped with a total of 11 units. Together with the transport vehicle and the liquid supply vehicle, they form the most basic fire extinguishing unit.
Lin Gang, Chief of the Operational Training Section of the Luzhou Fire Rescue Detachment, introduced that in August last year, in order to comprehensively strengthen the modernization of fire and rescue capabilities, accelerate the transformation and upgrading of fire rescue forces, make every effort to solve the problem of fire fighting and rescue, and reduce casualties, the Luzhou Fire Rescue Detachment The first rescue team of firefighting robots in the province was established. Fire-fighting robots can effectively replace fire-fighting officers to enter the scene of an accident when faced with various dangerous and complex environments such as high temperature, dense smoke, toxic, and hypoxia. These fire-fighting robots are driven by high-temperature flame-retardant rubber crawlers. They have an internal metal frame and are connected to a water supply belt at the rear. They can operate at a distance of 1 km from the rear console. The best effective combat range is 200 meters, and the effective jet range is 85. Meter.
Interestingly, fire-fighting robots are not actually more resistant to high temperatures than humans. Although its shell and track can withstand high temperatures, the normal working temperature of the internal electronic components must be controlled below 60 degrees Celsius. What to do in the scorching fire? It has its own cool trick-in the middle of the robot’s body, there is a raised cylindrical probe, which can monitor the temperature of the robot’s working environment in real time, and immediately sprays water mist on the body when abnormalities are found, like a “protective cover”.
Currently, the brigade is equipped with 38 special robots and 12 robot transport vehicles. In the future, they will play an active role in the rescue of inflammable and explosive places such as petrochemical industry, large-span and large spaces, underground buildings, etc.
Scene 2 A high-rise building caught fire, and 72 residents were trapped by a drone group lifted off to rescue and put out the fire
In addition to emergency response, command and disposal, and force projection, on-site rescue is also an important part of the exercise. The exercise set up 12 subjects including search and rescue of buried pressure personnel in buildings, fire extinguishing of high-rise buildings, disposal of gas pipeline leakage in gas storage and distribution stations, and fire extinguishing of hazardous chemical storage tanks.
Among them, the on-site rescue of high-rise building fire-fighting subjects simulated a fire in Building 5 of Binhe High-rise Residential District, Daxing Town, Yucheng District, Ya’an City. 72 residents were trapped indoors, roofs and elevators in a critical situation.
At the exercise site, the Heping Road Special Service Fire Station and the Mianyang professional team laid water hoses, threw fire bombs, and used high-jet fire trucks to snipe the fire spreading to the roof. The staff of Yucheng District and Daxing Town quickly organized emergency evacuation of residents. Heping Road Special Service Fire Station rushed to the scene immediately and used reconnaissance equipment to find out the damage to the high-rise building structure after the earthquake and the safety of internal attacks, as well as the fired floors and trapped buildings. The situation of the personnel, the rescue was quickly launched.
After determining the route, rescuers launched an internal rescue and external attack. The drone group of the Mianyang professional team immediately lifted off, and the No. 1 drone threw protective and life-saving equipment at the trapped people at the top. Subsequently, UAV No. 2 hovered in the airspace on the roof and dropped fire extinguishing bombs downwards. UAV No. 3 and No. 4 launched foam fire extinguishing agent and dry powder fire extinguishing agent injection operations into the building respectively.
According to the on-site commander, the high-level space location is special, and the way to climb is often blocked by fireworks. It is difficult for firefighters to reach the location of the fire site for a while. Using drones to organize external attacks is an important means. The outside attack of the UAV group can shorten the battle start time and has the characteristics of maneuverability and flexibility. UAV aerial delivery equipment is a tactical innovation for high-level rescue methods. At present, the technology is maturing day by day.
