[0029] A heating wire 15 is respectively provided in the two circular shells 14, and electrodes at both ends of the two heating wires 15 pass through and are fixedly connected to the corresponding circular shells 14 respectively. The two heating wires 15 are respectively arranged in the corresponding arc-shaped cavity 13, and the edges of the two circular shells 14 are respectively threadedly connected to the corresponding covers 18.

[0030] The two housings 11 are respectively fixedly connected to the corresponding temperature sensors 2 .

[0031] The inner walls of the two shells 11 are respectively fixedly connected to a corresponding pair of U-shaped gaskets 16 .

[0032] The inner walls of the two shells 11 are respectively fixedly connected to a corresponding pair of arc-shaped gaskets 17 .

[0033] The corresponding pair of U-shaped gaskets 16 are connected to the edges of the corresponding pair of arc-shaped gaskets 17 .

[0034] Working principle: first, two arc-shaped cavities 13 are placed on the pipe 3, so that the edges of the two arc-shaped cavities 13 fit together to wrap the pipe 3, and two heat-insulating covers 12 are placed outside the two arc-shaped cavities 13, so that two circular shells 14 pass through the two heat-insulating covers 12, so that the edges of the two heat-insulating covers 12 fit together, and two shells 11 are placed outside the two heat-insulating covers 12, so that the two circular shells 14 pass through the two shells 11 respectively, and the edges of the two shells 11 are fixed by bolts, and two covers 18 are screwed on, and at the same time, the arc-shaped gasket 17 and the U-shaped gasket 16 can fit the pipe 3 more closely, so that the protection module 1 can wrap the pipe 3 more tightly;

When the temperature sensor 2 senses that the temperature of the pipeline 3 is low, a signal is fed back to the external controller to control the external power supply to start, so that the two heating wires 15 are heated, and the temperature in the arc cavity 13 is increased. Through the layers of insulation of the heat preservation cover 12 and the outer shell 11, the temperature of the pipeline 3 is maintained at a suitable temperature.
