For example, when the temperature in the tank 1 is greater than or equal to a predetermined value, the temperature sensor 53 may send temperature data to the control device 7, and the control device 7 may control the fire hose to be opened according to the temperature data. When the temperature in the box body 1 is less than the preset value, the temperature sensor 53 does not send temperature data to the control device 7, and the control device 7 controls the fire fighting pipe to be closed.

In addition, the valve body 611 is fixed in the box body 1, the baffle 613 is located outside the box body 1, and initially, the baffle 613 abuts against the first box wall 11 to close the exhaust hole 12.

In particular, the suction device 62 is mounted on the side of the valve body 611 facing away from the wall of the first tank 1. Further, the air extracting device 62 may be an exhaust fan or the like.
