Description

Technical Field

[0001] The utility model relates to the technical field of mobile charging cabins, and particularly relates to a safety protection device for a mobile charging cabin. Background Art

[0002] Mobile charging bays are a convenient charging solution that can provide timely energy support when electric vehicles are running low on power;

[0003] At present, mobile charging cabins are basically equipped with large mobile power supplies and charging piles. When in use, the mobile power supply provides power, and the charging piles charge the new energy electric vehicles. In this process, both the mobile power supply and the charging piles will generate heat. Therefore, fire extinguishers are generally equipped on mobile charging cabins. When a fire occurs, the fire extinguishers are used to extinguish the fire in the mobile charging cabin.

[0004] In the above operation process, it takes time from discovering the fire to taking out the fire extinguisher and opening the fire extinguisher to extinguish the fire. In addition, there are operational errors in the operation process, which prolongs the time and easily misses the best time to extinguish the fire.

[0005] In order to solve the above problems, a mobile charging cabin safety protection device is proposed in the present application. Utility Model Content

[0013] A cover plate is detachably mounted on the top cover, bolts are mounted on the cover plate, and the cover plate is connected to the top cover via the bolts. The operation port can be easily covered by providing the cover plate and the bolts.

[0014] The fixing assembly comprises a slot plate installed on the top of the safety cabin, the carbon dioxide tank is placed on the slot plate, an elastic band is installed on the slot plate, and the position of the carbon dioxide tank is conveniently fixed by setting the fixing assembly.

[0015] The reminder structure includes an alarm installed on the top cover and a rotor-type airflow switch installed on the T-tube. The rotor-type airflow switch is electrically connected to the alarm. By setting the reminder structure, it is used to remind the operator of a fire.

[0016] The beneficial effects of the utility model are:

[0017] By setting up a pre-fire extinguishing structure, the carbon dioxide tank is always kept open, and the carbon dioxide gas in the carbon dioxide tank rushes into the airbag, causing the airbag to expand. When the charging pile or power source catches fire, the flame burns the airbag. At this time, a large amount of carbon dioxide gas rushes from the airbag into the safety cabin to reduce the oxygen in the safety cabin, achieving the effect of timely fire extinguishing;

[0018] By setting up a reminder structure, when the carbon dioxide gas in the carbon dioxide tank quickly passes through the rotor-type airflow switch, the rotor-type airflow switch sends a signal to the alarm. After receiving the signal, the alarm sounds an alarm, which is used to promptly remind surrounding people and vehicles to stay away, and at the same time remind staff to extinguish the fire.

After receiving the signal, the alarm 502 sounds an alarm, which is used to promptly remind surrounding personnel and vehicles to stay away, and at the same time remind staff to extinguish the fire.

[0037] Among them, the specific model of the rotor airflow switch 501 is: F61 Series, the specific model of the alarm 502 is: BSJ-ZP30, the circuit connection method of the rotor airflow switch 501 and the alarm 502 can be reasonably set according to actual conditions, and the specific signal transmission is the existing technology.

[0038] Working principle:

[0039] In the mobile charging cabin safety protection device, under normal conditions, the carbon dioxide tank 401 is always kept open, and the carbon dioxide gas in the carbon dioxide tank 401 rushes into the airbag 405, causing the airbag 405 to expand. When the charging pile or power supply catches fire, the flame burns the airbag 405. At this time, a large amount of carbon dioxide gas rushes from the airbag 405 into the safety cabin 1 to reduce the oxygen in the safety cabin 1, thereby achieving the effect of timely extinguishing the fire.

[0040] In the mobile charging cabin safety protection device, when the carbon dioxide gas in the carbon dioxide tank 401 quickly passes through the rotor-type airflow switch 501, the rotor-type airflow switch 501 sends a signal to the alarm 502. After receiving the signal, the alarm 502 emits an alarm sound, which is used to promptly remind surrounding people and vehicles to stay away, and at the same time remind staff to extinguish the fire.
