When in use, when severe cold weather comes, it will easily cause the water pipe 1 in the water conservancy and hydropower equipment to freeze. In order to prevent the water pipe 1 from freezing, the heating rod 3 is energized, and the heating rod 3 heats the antifreeze to increase the temperature of the antifreeze. The antifreeze heats the water pipe 1. Due to the insulation effect of the insulating tube 2, the heat exchange between the antifreeze and the outside is less, which plays a role of heat preservation, thereby helping to reduce power consumption and play a role of energy saving.

[0029] By arranging the water pipe 1, the insulated pipe 2 and the heating rod 3, and injecting antifreeze between the insulated pipe 2 and the water pipe 1, the antifreeze can be conveniently heated by the heating rod 3, and the water pipe can be heated by the heat transfer of the antifreeze to prevent the water pipe 1 from freezing. The heat insulation effect of the insulated pipe 2 can effectively reduce heat loss, thereby achieving the effect of energy saving and consumption reduction.

[0030] Embodiment 2:

[0031] like Figure 1-2As shown, a first flange 4 is fixedly installed at the end of the insulation tube 2, a sealing sleeve 5 is installed on the first flange 4, the end of the heating rod 3 passes through the sealing sleeve 5, a sealing ring 7 is installed between the first flange 4 and the water pipe 1, and the sealing ring 7 is used for sealing between the first flange 4 and the water pipe 1. When in use, the insulation tube 2 and the water pipe 1 are sealed by the sealing ring 7, and the heating rod 3 and the first flange 4 are sealed by the sealing sleeve 5, thereby sealing the installation cavity, and the antifreeze liquid therein will not leak to the outside, and when the heating rod 3 is damaged, the heating rod 3 is directly pulled out of the sealing sleeve 5, and the sealing sleeve 5 is temporarily blocked until a new heating rod 3 is installed.

[0032] By providing the first flange 4 , the sealing sleeve 5 and the sealing ring 7 , the installation cavity can be sealed, and the replacement of the heating rod 3 is convenient.

[0033] Embodiment 3:

[0034] like Figure 2 As shown, an embedding groove 8 is provided on the first flange 4, and the sealing ring 7 is installed in the embedding groove 8. When in use, the sealing ring 7 is put on the water pipe 1 and embedded in the embedding groove 8 from the outside until the inner side of the sealing ring 7 is blocked by the inner wall of the embedding groove 8 and cannot continue to move inward, thereby making the first flange 4 and the water pipe 1 sealed, and the sealing ring 7 will not enter the installation cavity.

[0035] By providing the first flange 4 with an embedding groove 8 , the installation of the sealing ring 7 can be facilitated.

[0036] Embodiment 4:

[0037] like Figure 1 and Figure 4 As shown, a second flange 6 is installed on one side of the first flange 4 , and the first flange 4 and the second flange 6 are connected by bolts. The second flange 6 blocks the sealing ring 7 from the outside to limit the sealing ring 7 .

[0038] By installing the second flange 6 on one side of the first flange 4 , the sealing ring 7 can be conveniently limited.

[0039] Embodiment 5:

[0040] like Figure 4 As shown, a mounting hole 9 is opened on the second flange 6, and the mounting hole 9 is aligned with the sealing sleeve 5 for installation, and then the second flange 6 is connected to the first flange 4 using bolts, and then the heating rod 3 is inserted into the sealing sleeve 5 through the mounting hole 9.

[0041] By providing the second flange 6 with the mounting hole 9 , the heating rod 5 can be easily installed.

[0042] Embodiment 6:

[0043] like Figure 3 As shown, an annular groove 10 is provided on the sealing sleeve 5. When installed, the annular groove 10 is clamped on the hole of the first flange 4, and its two ends are respectively clamped on the two ends of the first flange 4, so that the sealing sleeve 10 is not easy to fall out of the installation position.

[0044] By providing the annular groove 10 on the sealing sleeve 5 , the sealing sleeve 10 can be conveniently limited to prevent it from falling off the first flange 4 .

[0045] Working principle: When in use, when severe cold weather comes, it will easily cause the water pipe 1 in the water conservancy and hydropower equipment to freeze. In order to prevent the water pipe 1 from freezing, the heating rod 3 is energized, and the heating rod 3 heats the antifreeze to increase the temperature of the antifreeze. The antifreeze heats the water pipe 1. Due to the insulation effect of the insulation pipe 2, the antifreeze has less heat exchange with the outside world, which plays a role of heat preservation, which is beneficial to reduce power consumption and play a role of energy saving.
