[0021] An upper connecting nozzle 2 is fixedly connected to the upper part of the float 1, and a lower connecting nozzle 5 is fixedly connected to the lower part of the float 1. The heating tube 3 is distributed between the upper connecting nozzle 2 and the lower connecting nozzle 5. The upper connecting nozzle 2 and the lower connecting nozzle 5 are the structures of the existing float water level gauge on the market. At the same time, the upper connecting nozzle 2 and the lower connecting nozzle 5 are used in a way that they are convenient to form a communicating vessel principle with an external water tank.

[0022] A scale plate 4 is fixedly connected to the front of the buoy 1, and the rear side of the scale plate 4 does not abut against the heating tube 3. A flange interface 16 is fixedly connected to the lower part of the buoy 1, and the flange interface 16 is fixedly connected to the lower connecting head 6 by bolts. The scale plate 4 and the flange interface 16 are structures in the existing float water level gauge on the market.

[0023] A protective shell 10 is fixedly connected to the heating tube 3 above the temperature sensor 12, and the control module 11 is embedded in the protective shell 10. The end of the wire of the control module 11 that is away from the electric heating wire 9 passes through the protective shell 10. At the same time, a sealing ring is embedded in the part where the control module 11 and the protective shell 10 pass through. The function of the protective shell 10 is to protect the control module 11. The setting of the sealing ring can prevent external objects from entering the interior of the protective shell 10.

When the temperature sensor 12 detects that the temperature around the heating tube 3 is a composite preset value, the temperature sensor 12 transmits a signal to the control module 11, and then the control module 11 starts the electric heating wire 9 to work. The heat generated by the electric heating wire 9 can be transferred to the heating tube 3 through the heat-conducting medium 15. At this time, the heating tube 3 can be evenly heated, and the heat on the heating tube 3 can be transferred to the buoy 1, so that the buoy 1 can have a good antifreeze effect. When the temperature sensor 12 detects that the temperature around the heating tube 3 is a composite preset value, the temperature sensor 12 transmits a signal to the control module 11, and then the control module 11 starts the electric heating wire 9 to stop working.
