Several slide plates 8 are tilted and evenly distributed on the inner circumference of the second mounting ring 6. The slide plate 8 is connected to the corresponding slide groove 7 by a spring 10. One end of the spring 10 is fixedly connected to the side wall of the slide plate 8, and the other end of the spring 10 is fixedly connected to the inner wall of the slide groove 7. A fusible metal wire 9 is provided between the slide plate 8 and the corresponding slide groove 7. One end of the metal wire 9 is fixedly connected to the side wall of the slide plate 8, and the other end of the metal wire 9 is fixedly connected to the inner wall of the slide groove 7. Before the metal wire 9 is not fused, the elastic member is in a compressed state. A driving device for driving the first mounting ring 5 to rotate is provided on the fire extinguishing foam storage tank 1. The driving device, the sensing device, the control device and the fire extinguishing mechanism are electrically connected. The utility model has a simple structure and an ingenious design. It can not only accurately extinguish the fire source, but also extinguish a large range of fires. It can be applied to a variety of situations, improve the safety of the fire extinguishing device, meet actual needs, and is suitable for promotion. When using the utility model, when the fire is small, the driver can observe in the cab and promptly control the sprinkler head 3 to aim at the fire source for accurate fire extinguishing. The specific method is to control the driving device through the control device to provide power to the first mounting ring 5, and the first mounting ring 5 rotates to drive the sprinkler head 3 to rotate. When the sprinkler head 3 is aimed at the fire source, the control valve 11 is opened to enable accurate fire extinguishing. When the fire is fierce but the circuit of the fire extinguishing device is not damaged, the driving device is controlled by the control device to provide power to the first mounting ring 5, so that it drives the sprinkler head 3 to rotate quickly to extinguish the surrounding flames. Fire extinguishing work; when part of the fire extinguishing work is carried out, but the fire is still not extinguished, and even the flame causes damage to the circuit, and the driving device cannot provide power for the first mounting ring 5, in order to ensure safety, the driver needs to escape from the cab. At this time, the ambient temperature of the fire extinguishing foam storage tank 1 is higher than the melting point of the metal wire 9, and the metal wire 9 melts. Under the elastic force of the spring 10, the slide plates 8 slide out of the slide grooves 7 respectively. At this time, under the impact force of the high-pressure fire extinguishing foam spraying and the action of several slide plates 8, several slide plates 8 drive the first mounting ring 5 and the nozzle 3 to rotate to extinguish the fire around.
[0016] Specifically, as shown in the figure, the sensing device described in this embodiment includes a temperature sensor, a smoke sensor, a photoelectric sensor, and a pressure sensor, and the temperature sensor, the smoke sensor, the photoelectric sensor, and the pressure sensor are fixedly installed on the vehicle battery. Existing new energy vehicles all use lithium-ion batteries as power systems, and lithium-ion batteries have certain safety hazards during vehicle operation, especially in the case of abuse, such as overcharging, over-discharging, squeezing, puncture, fire, etc. during the charging process of the vehicle, lithium-ion batteries are prone to smoke, fire, and even explosion safety accidents. Through the induction of temperature sensors, smoke sensors, photoelectric sensors, and pressure sensors, battery abnormalities can be detected in time, so that the control mechanism and the fire extinguishing mechanism can take timely response measures.
[0017] Further, as shown in the figure, the control device of this embodiment includes a control chip, a power supply, a power switch and an alarm. The control chip, the power switch and the alarm are all installed at the vehicle operation console. The power supply is installed in the vehicle compartment. The power supply can provide power to the control valve 11. The signal from the sensing device is transmitted to the power switch and the alarm through the control chip. The power switch enables the power supply to provide power to the control valve 11, so that the control valve 11 is opened, so that the high-pressure fire extinguishing foam stored in the fire extinguishing foam storage tank 1 is sprayed out through the nozzle 2, and the alarm sounds an alarm to attract the attention of personnel.
[0018] Furthermore, as shown in the figure, the driving device described in this embodiment includes a stepper motor 40, which is a type of motor that can accurately control the rotation angle and the shaft can be freely twisted after power failure. The stepper motor 40 is fixedly installed on the fire extinguishing foam storage tank 1, and a coaxial gear 41 is fixedly installed on the output shaft of the stepper motor 40. A gear ring 42 is meshed and matched on one side of the gear 41. The gear ring 42 is coaxially fixedly installed on the first mounting ring 5, and the inner periphery of the gear ring 42 is fixedly connected to the outer periphery of the first mounting ring 5. The rotation of the output shaft of the stepper motor 40 drives the gear 41 to rotate, and the rotation of the gear 41 drives the gear ring 42 and the first mounting ring 5 to rotate.
[0019] Furthermore, as shown in the figure, the outer periphery of the first mounting ring 5 of the present embodiment is rotatably mounted on a circular ring 50 through a sealed bearing, a through hole 51 is provided at the bottom of the slide groove 7, the metal wire 9 passes through the through hole 51 and is fixedly connected to the inner periphery of the circular ring 50, a single-edged blade 52 is fixedly mounted on the inner periphery of the circular ring 50 corresponding to the metal wire 9, a blocking rod 53 is fixedly mounted on the outer periphery of the circular ring 50, a vertical rod 54 is fixedly mounted on the fire extinguishing foam storage tank 1, and a short rod 55 is rotatably mounted on the upper end of the vertical rod 54 through a torsion spring, and in the absence of external force, the short rod 55 remains coaxial with the vertical rod 54, and the short rod 55 can only rotate toward one side of the vertical rod 54, and in the present embodiment, the short rod 55 can only rotate toward the front side of the vertical rod 54. When there are many fire points, but they are all located around the fire extinguishing foam storage tank 1, the metal wire 9 fails to melt in time because it has not reached the melting point. At this time, the operator can control the output shaft of the stepper motor 40 to rotate forward through the control device, thereby driving the first mounting ring 5 to rotate forward. Under the connection of the metal wire 9, the ring 50 and the baffle rod 53 can rotate with the first mounting ring 5. When the baffle rod 53 rotates to abut against the short rod 55, it is blocked by the short rod 55, and the ring 50 and the baffle rod 53 cannot rotate with the first mounting ring 5. At this time, the single-edged blade 52 cuts the metal wire 9 When the first mounting ring 5 is in the state of being energized by the first stopper 53, the first stopper 53 is engaged with the first stopper 54 and the second stopper 55 is engaged with the first stopper 54. When the first stopper 53 is engaged with the first stopper 54, the first stopper 53 is engaged with the first stopper 54 and the second stopper 55 is engaged with the first stopper 54. When the first stopper 53 is engaged with the first stopper 54, the first stopper 53 is engaged with the first stopper 54 and the second stopper 55 is engaged with the first stopper 54. When the first stopper 53 is engaged with the first stopper 54, the first stopper 53 is engaged with the first stopper 54 and the second stopper 55 is engaged with the first stopper 54.
