This invention discloses a low-temperature antifreeze energy metering box, belonging to the technical field of energy metering boxes. It includes a metering box body with an internal guide baffle with a drain hole; a floating water-receiving mechanism located at the bottom of the box body, including a receiving unit, a dropping unit, and an opening / closing unit; the receiving unit includes a fixed box with a drain pipe connected to its bottom and a floating box movably inserted therein; the dropping unit includes a synchronizing rod and a magnetic threshold assembly; the sealing assembly includes a sealing ball plug that seals the drain pipe and a connecting lever connected to the synchronizing rod. This low-temperature antifreeze energy metering box uses a magnetic threshold assembly to set a trigger point. When the weight of the water in the floating box overcomes the magnetic attraction, it suddenly drops, triggering the synchronizing rod to pull out the sealing ball plug and simultaneously driving the sealing plate to flip open. The device normally maintains a double seal between the drain pipe and the leaking trough, effectively preventing cold air backflow, and only flushes and drains water momentarily when the water level reaches a certain threshold.
