Technical Field

[0001] The utility model relates to the technical field of direct-buried prefabricated thermal insulation pipes, in particular to a direct-buried thermal insulation pipe. Background Art

[0002] Energy-saving and environmentally friendly insulated pipes are special pipes for transporting combustible gases or liquids. Most energy-saving and environmentally friendly insulated pipes are one-piece circular pipes. The gas will cause a certain amount of pressure on the pipe wall during the transportation process. The pipe is made of corrosion-resistant, pressure-resistant, safe and environmentally friendly materials.

[0003] The existing environmentally friendly prefabricated direct-buried insulated pipes cannot filter the dirt inside the fluid during long-term use, resulting in blockage. At the same time, the traditional prefabricated direct-buried insulated pipes cannot buffer the pressure caused by extrusion during use, resulting in the prefabricated direct-buried insulated pipes being easily deformed. For this reason, we disclose a direct-buried insulated pipe. Utility Model Content

[0020] A filter fixing structure 5 is installed inside the upper part of the thermal insulation layer 8, and the filter fixing structure 5 includes a fastening spring 503, a fixing pin 502 and a mounting groove 501. A mounting groove 501 is opened inside the upper part of the thermal insulation layer 8, and one end of the fastening spring 503 is connected to the upper part of the mounting groove 501, and the other end of the fastening spring 503 is connected to one end of the fixing pin 502. A positioning pin groove 11 is opened above the outer side of the filter frame 7, and the other end of the fixing pin 502 is connected to the inside of the positioning pin groove 11. The fixing pin 502 is used in conjunction with the positioning pin groove 11 to quickly fix the filter frame 7 and facilitate disassembly. Stable grooves 501 are opened on both sides of the interior 4. One end of a stabilizing rod 505 is slidably connected inside the stabilizing groove 504, and the other end of the stabilizing rod 505 is connected to both sides of the fixing pin 502. The stabilizing rod 505 is used in conjunction with the stabilizing groove 504 to limit the movement of the fixing pin 502 and prevent the fixing pin 502 from deflecting.

[0021] The working process and principle of the utility model are as follows: during installation, the first protective layer 2 is placed at the bottom of the installation groove, and the second protective layer 4 protects the upper part of the thermal insulation layer 8. During use, the filter 6 inside the filter frame 7 filters impurities in the fluid. During use, the second protective layer 4 receives pressure and drives the shock absorber 3 to contract and store force. The shock absorber 3 buffers the pressure and converts it into damping force. When the filter 6 needs to be replaced, the fixing pin 502 inside the sliding filter fixing structure 5 drives the fastening spring 503 to contract and store force. At the same time, the fixing pin 502 is pulled out of the positioning pin groove 11, and then the filter frame 7 and the filter 6 are replaced. During installation, the fastening spring 503 pushes out the fixing pin 502 and inserts it into the positioning pin groove 11 inside the filter frame 7 for fixing.
