[0028] During implementation, the float body 301 changes with the change of the water volume in the device body 1. When the water volume inside the device body 1 decreases, the T-shaped float rod 3034 is driven downward by the action of the float body 301, so that the T-shaped float rod 3034 slides inside the float body 301, thereby driving the alarm plate 3033 to move downward.

The surface of the rotating handle 402 is threadedly connected with a fastening stud 4032, and one end of the fastening stud 4032 passes through the rotating handle 402 and is threadedly fastened to the surface of the electric sprinkler 108.

[0030] During implementation, the user loosens the fastening studs 4032 on the surface of the rotating handle 402, and then rotates the rotating handle 402 to make the rotating handle 402 rotate on the surface of the electric sprinkler 108. At this time, the rotating handle 402 drives the slider body 4031 to slide inside the slide groove body 4033, and the rotating handle 402 is guided under the joint action of the slider body 4031 and the slide groove body 4033. When the rotating handle 402 is rotated, the rotating handle 402 drives the water baffle plate 401 to rotate until it contacts the surface of the water outlet hole 109, and adjusts the water baffle plate 401 to the desired position, so that water can be sprayed out through the gap between the water outlet hole 109 and the water baffle plate 401, and spray cooling treatment is performed to realize the function of the automatic fire extinguishing device to adjust the water output of the electric sprinkler 108.

[0031] Working principle: When in use, first place the device body 1 at the designated position, and the user places the dry powder fire ball 101 on the surface of the carport body 103. At this time, the dry powder fire ball 101 drives the mounting frame 202 to move to the bottom of the carport body 103. At this time, the mounting frame 202 drives the positioning card 204 to be clamped into the inside of the positioning card slot 205. Under the joint action of the positioning card 204 and the positioning card slot 205, the dry powder fire ball 101 is positioned and installed. At this time, the arc-shaped card 206 is driven to move under the elastic force of the extension spring 203 inside the groove, so that the arc-shaped card 206 is The clamp 206 is clamped to the inner wall of the carport body 103, and then the user tightens the mounting studs 201 on the surface of the mounting frame plate 202, and the dry powder fire ball 101 is installed on the inner wall of the carport body 103 under the action of the mounting studs 201, and the fire is extinguished under the action of the dry powder inside the dry powder fire ball 101, so as to realize the function of the automatic fire extinguishing device to stably install the dry powder fire ball 101, so that the automatic fire extinguishing device can install the dry powder fire ball 101 on the inner wall of the carport body 103 at a high temperature when in use, thereby avoiding the phenomenon of the automatic fire extinguishing device falling during use.

[0032] Subsequently, the smoke is sensed and an alarm is sounded under the action of the smoke sensor 110. When a fire occurs in the battery vehicle, the smoke sensor 110 controls the dry powder fire ball 101 to automatically explode, and the dry powder inside the dry powder fire ball 101 is sprinkled to extinguish the fire of the battery vehicle. Subsequently, when it is sensed that the temperature on the surface of the fireproof partition 102 is too high, the smoke sensor 110 controls the electric nozzle 108 on the surface of the water pipe 105 to operate, and the water inside the device body 1 is introduced into the inside of the water pipe 105 through a pipe. Under the action of the electric nozzle 108, the water is sprayed through the water outlet 109, thereby spraying and cooling the surface of the fireproof partition 102, and monitoring the surrounding environment is monitored under the action of the monitoring device 104.

[0033] Subsequently, when the user needs to adjust the spraying amount of the electric spray head 108, the user loosens the fastening stud 4032 on the surface of the rotating handle 402, and then rotates the rotating handle 402, so that the rotating handle 402 rotates on the surface of the electric spray head 108. At this time, the rotating handle 402 drives the slider body 4031 to slide inside the slide groove body 4033. Under the joint action of the slider body 4031 and the slide groove body 4033, the rotating handle 402 is guided. When the rotating handle 402 rotates, the rotating handle 402 drives the stopper 4031 to slide inside the slide groove body 4033. The water plate 401 rotates to contact the surface of the water outlet 109, and the water baffle 401 is adjusted to the required position, so that water can be sprayed out through the gap between the water outlet 109 and the water baffle 401, and spraying and cooling treatment are performed to realize the function of the automatic fire extinguishing device to adjust the water output of the electric sprinkler 108, so that the automatic fire extinguishing device can control the water output of the electric sprinkler 108 as needed when in use, so that the automatic fire extinguishing device can better meet the user's usage needs when in use, and is not easy to cause waste of water resources.

[0034] Subsequently, when the amount of water inside the device body 1 changes, the float body 301 changes with the change of the amount of water inside the device body 1. When the amount of water inside the device body 1 decreases, the T-shaped float rod 3034 is driven downward by the action of the float body 301, so that the T-shaped float rod 3034 slides inside the float body 301, thereby driving the alarm plate 3033 to move downward. When the alarm plate 3033 contacts the surface of the alarm 3032 at the bottom of the monitoring box 302, the alarm 3032 sounds an alarm, indicating that the amount of water inside the device body 1 is too little and water replenishment is required in time, so as to realize the function of the automatic fire extinguishing device to monitor the amount of water inside the device body 1, thereby avoiding the phenomenon of insufficient water inside the device body 1 during the use of the automatic fire extinguishing device, and being able to promptly remind the staff to inject water resources into the device body 1, thereby ensuring that the automatic fire extinguishing device can be used normally, and finally completing the use of the automatic fire extinguishing device.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
