Its main purpose is to help the heated object to maintain a reasonable temperature range, avoid problems such as pipeline medium solidification and pipeline freezing caused by too low temperature, and ensure the normal operation of the pipeline; the working principle is to emit a certain amount of heat through the heating medium, and supplement the loss of the heated pipeline through direct or indirect heat exchange, so as to achieve the normal working requirements of heating, heat preservation or antifreeze.

[0003] Common electric heating equipment is mostly used on pipelines in the north to protect the pipelines from being frozen by low temperatures. Electric heating equipment is mostly installed on the outer wall of the pipeline to heat the inside. The fireproof insulation cover is a protective device that is mounted on the outside of the electric heating equipment. It can maintain the temperature and protect the electric heating equipment to reduce losses in the event of a fire. However, ordinary fireproof insulation covers are wrapped around the outside of the electric heating equipment. Affected by the shape of the pipeline, the installation of the fireproof insulation cover is relatively difficult, which has prevented the utilization rate from being improved. Utility Model Content

[0022] Refer to Figures 1 - 6 , a fireproof and heat-insulating cover for an electric tracing device that is easy to install, including a heat-insulating cover assembly 1. A fireproof layer 2 is arranged on the outer wall of the heat-insulating cover assembly 1. An endothermic layer 3 is fixedly connected to the inner wall of the fireproof layer 2. A heat-insulating layer 4 is fixedly connected to the inner wall of the endothermic layer 3. A waterproof layer 5 is fixedly connected to the inner wall of the heat-insulating layer 4. The heat-insulating cover assembly 1 includes an upper outer shell 6, a lower outer shell 7, a right closing cover 8, a lower closing cover 9, and a left closing cover 10. The upper outer shell 6 is slidably connected to the lower outer shell 7. The right closing cover 8 and the left closing cover 10 are both slidably connected to the upper outer shell 6. The lower closing cover 9 is slidably connected to the lower outer shell 7.

[0023] Furthermore, the sliding structure includes uniformly distributed positioning columns 11, limiting holes 12, positioning holes 13, and limiting columns 14. The positioning columns 11 are fixedly connected to the right outer wall of the upper outer shell 6. The limiting holes 12 are arranged at the bottom end of the upper outer shell 6. The positioning holes 13 are arranged on the left outer wall of the upper outer shell 6. The limiting columns 14 are fixedly connected to the top end of the lower outer shell 7.

[0024] Among them, the limiting column 14 is arranged in an L shape, and the edge of the protruding end of the limiting column 14 is set to be arc-shaped, which is convenient for connection with the limiting hole 12.

[0025] Furthermore, the positioning column 11 is slidably connected to the positioning hole 13, the limiting column 14 is slidably connected to the limiting hole 12. The position and size of the positioning column 11 are mutually adapted to the position and size of the positioning hole 13. The shape and size of the limiting column 14 are mutually adapted to the shape and size of the limiting hole 12.

[0026] After the limiting post 14 is inserted into the limiting hole 12, it needs to be pushed forward further to complete the connection and fixation. After the pushing is completed, the outer walls on both sides of the upper housing 6 and the lower housing 7 are flush with each other.

[0027] Furthermore, sliding grooves 16 are formed on the outer walls of the right closing cover 8, the lower closing cover 9, and the left closing cover 10. At the bottom end of the inner wall of the sliding groove 16 on the right closing cover 8, insertion holes 18 are formed in a uniformly distributed manner.

[0028] Among them, the insertion holes 18 are slidably connected to the positioning posts 11, and the size of the inner wall of the sliding groove 16 is adapted to the width of the outer walls of the upper housing 6 and the lower housing 7.

[0029] Furthermore, a drain port 17 is formed in the inner wall of the sliding groove 16 on the lower closing cover 9, and a drain groove 15 is formed in the inner wall of the lower housing 7.

[0030] Among them, the position and size of the drain groove 15 are adapted to those of the drain port 17, and the drain port 17 penetrates through the outer wall of the lower closing cover 9, so that when the pipeline leaks water, the water can flow along the drain groove 15 to the drain port 17 and be discharged.

[0031] Furthermore, connecting posts 19 are fixedly connected to the bottom end of the inner wall of the sliding groove 16 on the left closing cover 10 in a uniformly distributed manner.

[0032] Among them, the position and size of the connecting posts 19 are adapted to those of the positioning holes 13, and the connecting posts 19 are slidably connected to the positioning holes 13.

[0033] Working principle: First, the interior of the heat preservation cover is composed of a fireproof layer, a heat absorption layer, a heat preservation layer, and a waterproof layer, which has good fireproof, heat preservation, and waterproof properties, and can greatly avoid the harm of fire and water pipe leakage to the heat preservation cover. Then, the limiting post 14 on the lower housing 7 is inserted into the limiting hole 12 on the upper housing 6 to achieve rapid connection, and the positioning post 11 and the positioning hole 13 can be slidably connected to each other, so that the length of the heat preservation cover can be adjusted accordingly, greatly improving the practicability of the heat preservation cover. Finally, the right closing cover 8, the lower closing cover 9, and the left closing cover 10 arranged on both sides can be respectively inserted into both sides of the upper housing 6 and the lower housing 7. While playing a role in closing both sides, they can hide the extra positioning posts 11 and positioning holes 13. The internal drain groove 15 and drain port 17 can drain the water leaked from the internal pipeline, reducing the influence of accumulated water on the electric tracing equipment.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
