[0003] There are many kinds of pipeline antifreeze devices at present. The most common ones are heating sleeves or heating belts fixed on the pipeline. The heating belt fixing method can be installed and removed on the installed pipeline, but the heating belt is often difficult to fully fit with the pipeline, and an additional rope is required to tie the heating belt to the pipeline, which affects the convenience of operation.

[0011] By adopting the above technical solution, when the position of the connecting seat needs to be fixed by a limiter, the staff can move the bite plate to the position in the tooth groove, and then fix it by a cross bar, thereby fixing the position of the connecting seat, which is conducive to improving work efficiency.

[0012] Optionally, a spring is provided between the other end of the cross bar and the connecting seat.

[0013] By adopting the above technical solution, the engagement state between the bite plate and the tooth groove can be ensured by setting a spring.

[0014] Optionally, the first fixing ring seat and the second fixing ring seat are each composed of two groups of half rings, and the ends of the two groups of half rings are detachably connected by bolts.

[0018] Optionally, a controller is provided in the connection seat, and the controller is electrically connected to the heating belt.

[0019] By adopting the above technical solution, when heating is required, the staff can control the controller to start the heating belt, which is easy to operate and conducive to improving work efficiency.

[0020] Optionally, the heating belt is circumferentially spirally arranged on the outside of the pipeline.

[0021] By adopting the above technical solution, the heating belt is spirally arranged on the outside of the pipeline to achieve uniform heating of the pipeline. The spiral heating belt can fit tightly to the surface of the pipeline so that heat can be evenly transferred to the pipeline, avoiding local overheating or uneven cooling.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The heating belt can be detachably fixed on the ground pipeline by using the fixed ring seat 1 and the fixed ring seat 2 at both ends of the heating belt to limit the laying length of the heating belt to prevent the heating belt from changing in length due to external force on the pipeline;

[0024] 2.
