The prefabricated direct -buried heat preservation pipe convenient to detect, through the setting of dismounting detection mechanism, under the mutual cooperation between each structure on the inner layer pipeline, the setting of detection interface can be conveniently detected in the case where the pipeline is not damaged, and the number of detection interfaces can be adjusted according to actual use demand, so that the working personnel can understand the use condition of the heat preservation pipe from multiple aspects, thereby helping to improve the use efficiency and safety of the pipeline and facilitating the detection of the heat preservation pipe by the working personnel.

[0004] However, the device still has certain problems, in the actual use process, the detection interface unlocking mechanism is often provided with two pull rods on a docking seat, this design leads to that in actual operation, the staff needs to pull two pull rods at the same time with two hands, to complete the unlocking action, which not only increases the complexity of operation, but also reduces the working efficiency, and more inconveniently, after the pull rod is pulled, another staff needs to assist to take down the sealing cover, to insert the detection instrument into the detection interface to detect, this multi-step, multi-personnel cooperation operation mode undoubtedly increases the complexity and time cost of the whole detection process, therefore we propose a prefabricated direct -buried heat preservation pipe convenient to detect to solve the above problems.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-5As shown in the figure, an embodiment of the present invention provides a prefabricated direct-buried insulated pipe that is easy to inspect, including an insulated pipe body 1. Multiple connecting pipes 2 are connected and fixed to the top of the insulated pipe body 1. A sealing cap 3 is movably contacted at the top of each connecting pipe 2. Two cavities 4 are formed on each connecting pipe 2. Two U-shaped blocks 5 are fixedly connected to both sides of each connecting pipe 2. Guide rods 6 are welded between the inner walls of the two sides of the U-shaped blocks 5. Limiting rods 7 are slidably connected to the guide rods 6. A first spring 8 is welded between one side of the limiting rod 7 and the inner wall of the corresponding U-shaped block 5. A common locking pin 9 is fixedly connected between the two limiting rods 7 on the same side. The end of the locking pin 9 extends into the corresponding cavity 4. A movable ring 10 is fitted onto the connecting pipe 2. Two hinged rods 11 are rotatably connected to the top of the movable ring 10. The ends of the hinged rods 11 are hinged to one side of the corresponding locking pin 9. Two mounting blocks 12 are fixedly connected to the bottom of the sealing cap 3. A slot 13 is formed on the mounting block 12, and the slot 13 is connected to the corresponding locking pin. Pin 9 is engaged, and a first sealing ring 14 is fixedly connected to the bottom of the sealing cover 3. A second sealing ring 15 is fixedly connected to the inner wall of the connecting pipe 2. The second sealing ring 15 is in contact with the corresponding first sealing ring 14. Moving the moving ring 10 causes the corresponding slider 18 to slide on the positioning rod 17 and compress the second spring 19. At the same time, the moving ring 10 drives the corresponding locking pin 9 to move through the hinge rod 11. The locking pin 9 drives the limiting rod 7 to slide on the corresponding guide rod 6. During the movement, the limiting rod 7 compresses the corresponding first spring 8, causing the locking pin 9 to separate from the corresponding slot 13. Then, moving the sealing cover 3 causes the mounting block 12 to separate from the connecting pipe 2. Subsequently, a detection instrument, such as a temperature sensor or humidity sensor, can be inserted into the connecting pipe 2 to detect the temperature, humidity, and other parameters inside the insulation pipe body 1. Thus, the sealing cover 3 can be removed by a single person, thereby improving the convenience and efficiency of operation.

[0027] In some embodiments, the first spring 8 is movably sleeved on the corresponding guide rod 6, and the guide rod 6 serves a positioning function.

[0028] In some embodiments, grooves 16 are provided on both sides of the connector 2, and positioning rods 17 are welded between the inner walls of the two sides of the grooves 16.

[0029] In some embodiments, a slider 18 is slidably connected to the positioning rod 17, and one side of the slider 18 is fixedly connected to the inner wall of one side of the corresponding moving ring 10. The moving ring 10 serves as a connection.

[0030] In some embodiments, a second spring 19 is fixedly connected between the other side of the slider 18 and the inner wall of one side of the corresponding groove 16, and the second spring 19 is movably sleeved on the corresponding positioning rod 17.

[0031] In some embodiments, a rectangular hole 20 is provided on the top inner wall of the cavity 4, and the inner wall of the rectangular hole 20 is in movable contact with the outer side of the corresponding mounting block 12. The mounting block 12 serves as a connection.

[0032] The working principle or structural principle is as follows: During use, the moving ring 10 is moved, which drives the corresponding slider 18 to slide on the positioning rod 17 and compress the second spring 19. At the same time, the moving ring 10 drives the corresponding locking pin 9 to move through the hinge rod 11. The locking pin 9 drives the limiting rod 7 to slide on the corresponding guide rod 6. During the movement, the limiting rod 7 compresses the corresponding first spring 8, causing the locking pin 9 to separate from the corresponding slot 13. Then, the sealing cover 3 is moved, which drives the mounting block 12 to separate from the connecting pipe 2. Subsequently, a detection instrument, such as a temperature sensor or humidity sensor, can be inserted through the connecting pipe 2 to detect the temperature, humidity and other parameters inside the insulation pipe body 1. Thus, the sealing cover 3 can be removed by a single person, thereby improving the convenience and efficiency of operation.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
