[0026] Working principle: In the process of measuring the empty area of ​​the vehicle battery, if an abnormal situation occurs, a long stick is used, and one end of the long stick is embedded in the embedded frame head 11 to fix it, and then the stable bottom plate 10 and the auxiliary frame 1 are pushed to the side of the battery position by the long stick, and the auxiliary frame 1 is moved to the upper end of the battery. The intelligent control valve is remotely started by the remote control inside the control panel, and the fire extinguishing material inside the fire extinguishing equipment 405 is transported to the inside of the nozzle 401 through the air supply channel 408 and the porous air channel 403, and the fire extinguishing material is sprayed out through the nozzle 401 to extinguish the fire. When the fire does not reach the expected level, the booster pump 404 is started to The internal pressurization of the fire extinguishing device 405 improves the efficiency of the ejection of the fire extinguishing material. In the process of fire extinguishing, the fire extinguishing end is moved to the battery position over a long distance, and the fire is extinguished in an arched manner. The fire extinguishing range is wider and the fire extinguishing is more thorough. It can not only increase the efficiency of the fire extinguishing process, but also increase the protection of the staff through long-distance operation, and change the fire extinguishing power according to the change of the fire intensity, further suppress the fire, increase the efficiency of suppressing the fire when a fire occurs, and avoid the need for manual fire extinguishing operations when abnormal situations occur. If an abnormal situation occurs, it is easy to cause injuries to the staff; During the auxiliary fire extinguishing process, if the fire extinguishing effect is not achieved, when the fire spreads to the surroundings, the aluminum baffles 706 on both sides will be melted due to the high temperature, and the aluminum-zinc limit strip 705 will be melted, so that the guide ball 704 and the movable installation rod 702 lose their restraint force, and by pulling the elastic rope 703 in a stretched state, one end of the movable installation rod 702 and the guide ball 704 move toward the inner cavity of the monitoring frame head 701 with the hinge as the axis, and the guide ball 704 contacts the connecting guide block 707, so as to start the single-phase motor 506 and trigger the first electromagnetic block 805 and When the fire is bigger, one of the ports of the three-way solenoid valve 502 will make the fire higher and melt the aluminum baffle 706 at the top, thereby melting the aluminum-zinc limit strip 705 at the top, so that the movable mounting rod 702 and the guide ball 704 at the top lose their restraining force, and the movable mounting rod 702 and the guide ball 704 are driven to move by pulling the elastic rope 703 in a stretched state, so that the guide ball 704 at the top contacts the connecting guide block 707 at the top, and the second solenoid block 605 is started to trigger the double-headed solenoid block 509 and the other port of the three-way solenoid valve 502; When the single-phase motor 506 is started, the rotating rod 505 is driven to rotate, and the first turbofan 503 is driven to rotate through the rotating rod 505. The rotation of the first turbofan 503 generates airflow, and the airflow is transported to the inside of the first long slot 205 through the three-way electromagnetic valve 502. When the rotating rod 505 rotates, since there is no fixed connection with the second turbofan 504, the second turbofan 504 will not be driven to rotate. When the double-headed electromagnetic block 509 is triggered, the double-headed electromagnetic block 509 will generate magnetism, which will generate magnetic attraction with the fixed magnetic block 510 and drive the fixed magnetic block 510 to move to one side of the double-headed electromagnetic block 509, thereby stretching the rubber layer 50 8 is in contact and extrusion with the adsorption end of the double-headed electromagnetic block 509, and the rubber layer 508 is used to increase the tightness and fit of the fixing ring 507 when in contact with the outside of the rotating rod 505, and to increase the friction during contact, and the fixing ring 507 and the second turbofan 504 are driven to rotate through the rotating rod 505, and the first turbofan 503 and the second turbofan 504 are rotated at the same time, which will generate a larger airflow, and the airflow is transported to the first porous air channel 203 and the second porous air channel 305 respectively, and the airflow is transported to the inside of the first long slot 205 and the second long slot 303 respectively through the first porous air channel 203 and the second porous air channel 305; When the fire becomes larger, the circuit of the first electromagnetic block 805 is disconnected, and the first electromagnetic block 805 loses its magnetism, so that the first limit block 804 loses its restraining force, and the first limit rope 803 and the first slide bar 207 lose their restraining force. The first push spring 208 in a compressed state pushes the first slide bar 207 to slide inside the first slide rail 202, and the first slide bar 207 on the other side is driven to slide inside the first slide rail 202 through the connecting rod. When the first slide bar 207 slides inside the first slide rail 202, the limit elastic rope 904 in a stretched state also pulls the first slide bar 207 to slide inside the first slide rail 202. When the limit elastic rope 904 loses its restraint, the movable mounting block 901 loses its restraining force, and the movable mounting block 901 and the movable limit block 903 are driven by the mounting spring 903 in a stretched state. 6 moves, so that the movable limit block 906 is separated from the inside of the limit recess 905, so that the first baffle 201 loses its restraining force, and through the push of the first push spring 208 and the pull of the limit elastic rope 904, the first top ball 204 is driven to move quickly inside the first long groove 205 through the first slide bar 207, so that the first top ball 204 collides with the first baffle 201, and the first baffle 201 is ejected and separated from the inside of the first long groove 205, and the first shielding cloth 206 is driven by the first baffle 201 to move to the side away from the outside of the first long groove 205, and the airflow is blown into the inside of the first long groove 205, so that the airflow contacts the outside of the first shielding cloth 206, so that the first shielding cloth 206 can be fully unfolded in a short time, and when the first shielding cloth 206 is unfolded, it directly covers the outside of the battery to cover and isolate the air for fire extinguishing; When the fire is still not suppressed after the first layer of coverage, the control circuit of the second electromagnetic block 605 is disconnected, so that the second electromagnetic block 605 loses its magnetism, and the second limit block 604 and the second limit rope 603 lose their restraining force, and the second slide bar 307 loses its restraining force, and the second push spring 308 in a compressed state pushes the second slide bar 307 to slide inside the second slide rail 302, and the second slide bar 307 on the other side is driven to slide inside the second slide rail 302 through the connecting rod, and the limit elastic rope 9 in a stretched state is also driven. 04 pulls the second slide bar 307 to slide inside the second slide rail 302. When the limit elastic rope 904 loses its constraint, the movable mounting block 901 loses its constraint force, and the movable mounting block 901 and the movable limit block 906 are driven to move by the installation spring 903 in a stretched state, so that the movable limit block 906 is separated from the inside of the limit recess 905, so that the second stop bar 301 loses its constraint force, and the second top ball 306 is quickly driven to move by the second slide bar 307, so that the second top ball 306 collides with the second stop bar 301, and The second baffle 301 is ejected and drives the second shielding cloth 304 to move. At the same time, the increase in airflow allows the airflow to be transported to the inside of the second long groove 303 through the second porous airway 305, and the second shielding cloth 304 is quickly unfolded so that the second shielding cloth 304 covers the upper end of the first shielding cloth 206 to further suppress the fire. By adopting different degrees of covering methods, the efficiency in the fire extinguishing process is increased, and the protection ability for the staff in the fire extinguishing process is increased. By using different covering methods, the abnormal battery area is isolated from the outside, and while improving the processing ability, it can also have a blocking effect. Even if an abnormal problem occurs, it will not spread to the dangerous area. The color change of the covering end is used to warn the external staff, telling them that the fire situation of the battery has changed greatly and they need to stay away from the battery area, and be prepared for the worst to avoid the fire situation from continuing to change and causing harm to the staff, and the abnormal battery area will not produce more serious changes, and auxiliary processing cannot be continued, which increases the danger.
