[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment, a prefabricated direct-buried thermal insulation pipe that is easy to detect includes an inner pipe 1, and a disassembly and assembly detection mechanism is provided on the inner pipe 1.

[0023] In this embodiment, the disassembly and assembly detection mechanism includes an insulation layer 2 wrapped around the outside of the inner pipe 1, an outer pipe 3 is arranged on the outside of the insulation layer 2, a detection interface 4 is fixedly installed on the top of the outer pipe 3, and an installation groove is opened on the top of the outer pipe 3. The detection interface 4 is fixedly connected to the outer pipe 3 through the installation groove, which is convenient for the staff to detect the insulation pipe without damaging the insulation pipe, thereby allowing the insulation pipe to be used normally.

[0024] Among them, a detection channel is provided inside the detection interface 4, and one end of the detection channel is connected to the inside of the outer pipe 3, and the other end extends to the inside of the insulation layer 2, so that the staff can conveniently detect the internal insulation performance of the insulation pipe through the detection interface.

[0025] It should be added that there are multiple detection interfaces 4, which are evenly distributed along the length direction of the outer pipe 3, so that the thermal insulation performance can be tested at multiple positions to obtain more comprehensive data. Mounting seats 5 are fixedly installed on both sides of the detection interface 4, and a fixing rod 6 is fixedly installed inside the mounting seat 5. The outer side of the fixing rod 6 is sleeved with a spring 7 fixedly connected to the inner wall of the mounting seat 5.

[0026] Among them, a movable block 8 slidably connected to the fixed rod 6 is fixedly installed on the side of the spring 7 away from the inner wall of the mounting seat 5. The elasticity of the spring 7 abuts against the movable block 8, so that the position of the movable block 8 remains relatively fixed.

[0027] Among them, a pull rod 9 extending to the outside of the mounting seat 5 is fixedly installed on the side of the movable block 8 away from the spring 7, and a first through hole is opened on the side of the mounting seat 5 away from the detection interface 4. The pull rod 9 extends to the outside of the mounting seat 5 through the first through hole, which is convenient for the staff to pull the pull rod 9 through the first through hole to adjust the position. A limit frame 10 is fixedly installed on the top of the movable block 8, and the subsequent structure is installed and docked through the limit frame 10.

[0028] In this embodiment, the disassembly and assembly detection mechanism also includes a sealing cover 11 movably connected to the top of the detection interface 4, and docking seats 12 are fixedly installed on both sides of the sealing cover 11, and a plug-in block 13 is fixedly installed on the bottom of the docking seat 12. A plug-in slot is opened on the top of the mounting seat 5, and the plug-in block 13 extends to the interior of the mounting seat 5 through the plug-in slot, thereby fixing the sealing cover 11 and the detection interface 4.

[0029] Among them, a sealing ring 14 is arranged at the bottom of the sealing cover 11. When the sealing cover 11 contacts the top of the detection interface 4, the sealing ring 14 improves the sealing of the contact part, so that the sealing effect of the detection interface 4 is improved. A glass panel 15 is fixedly installed on the top of the sealing cover 11, so that the staff can check the inside of the insulation pipe more intuitively through the glass panel 15.

[0030] It should be noted that the prefabricated direct-buried insulated pipe, which is easy to inspect, can conveniently inspect the insulation performance and condition inside the pipe without damaging the pipe through the disassembly and assembly inspection mechanism, with the cooperation of various structures on the inner pipe 1, and the setting of the inspection interface 4, and the number of inspection interfaces 4 can also be adjusted according to actual use requirements, so that the staff can understand the use of the insulation pipe from all aspects, which helps to improve the efficiency and safety of the use of the pipe and facilitates the staff to inspect the insulation pipe.

[0031] The working principle of the above embodiment is:

[0032] The prefabricated direct-buried insulated pipe which is easy to detect is provided with the detection interface 4. When it is necessary to detect the pipe, first pull the pull rod 9 to drive the movable block 8 to move on the fixed rod 6. While moving, the spring 7 is pulled to extend. The movement of the movable block 8 drives the limit frame 10 to move to the side away from the detection interface 4, so that it is convenient for the staff to take out the sealing cover 11. Then, the detection instrument, such as temperature sensor, humidity sensor, etc., can be inserted through the detection interface 4 to detect the temperature, humidity and other parameters inside the pipe. The sensor is placed inside to monitor the internal temperature of the insulation layer 2, so as to determine whether the insulation pipe is damaged. The staff can also observe the insulation layer 2 through the glass panel 15 with the naked eye, so there is no need to open the sealing cover 11, thereby saving operation time and improving detection efficiency.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
