[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0030] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to "inside" and "outside" relative to the corresponding component's own outline. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0031] According to a specific embodiment of the present disclosure, a pipeline detection device is provided, referring to Figures 1 to 5 As shown in the figure, the pipeline detection device includes: a mounting frame, a detection mechanism and a plurality of clamping mechanisms 6. The mounting frame is sleeved outside the pipeline, and the detection mechanism is installed on the mounting frame for detecting the pipe wall of the pipeline. The plurality of clamping mechanisms 6 are arranged at intervals along the circumference of the pipeline, and the clamping mechanisms 6 are movably installed on the mounting frame to selectively abut against the outer wall of the pipeline.

[0032] Through the above technical solution, in the pipeline detection device provided by the present disclosure, multiple clamping mechanisms 6 can abut against the outer wall of the pipeline, and multiple clamping mechanisms 6 are arranged at intervals along the circumference of the pipeline, so that multiple clamping mechanisms 6 can be stably clamped on the outer wall of the pipeline; in addition, since the clamping mechanisms 6 and the detection mechanism are both installed on the mounting frame, the mounting frame and the detection mechanism can also be stably arranged outside the pipeline, so that the detection mechanism can detect the pipe wall of the pipeline. In addition, the clamping mechanism 6 is movably installed on the mounting frame, that is, multiple clamping mechanisms 6 can approach or move away from the pipeline at the same time, so the pipeline detection device can adapt to pipelines of different diameters.

[0033] It should be noted that the pipeline detection device can be applied to various types of pipelines, such as water pipelines, flue gas pipelines of thermal power plants, etc., and the present disclosure does not impose any limitation on this.

[0034] In the pipeline detection device provided in the present disclosure, the clamping mechanism 6 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 4 and Figure 5 As shown in , the clamping mechanism 6 may include a mounting tube 13, a connecting tube 61 and a ball 64. The mounting tube 13 may be fixed to the mounting frame, the connecting tube 61 may be movably mounted in the mounting tube 13 and extend radially along the pipeline, and the ball 64 may be connected to the connecting tube 61, and the connecting tube 61 may drive the ball 64 to move so that the ball 64 selectively abuts against the outer wall of the pipeline. In this way, the connecting tube 61 can move relative to the mounting tube 13 in the radial direction of the pipeline, that is, the connecting tube 61 can move relative to the mounting frame in the radial direction of the pipeline. When the pipeline detection device needs to be installed on pipelines of different diameters, it is only necessary to adjust the positions of multiple connecting tubes 61 relative to the mounting frame so that multiple ball 64 abut against the outer wall of the pipeline at the same time, so as to ensure the assembly stability of the pipeline detection device. Among them, the ball 64 can convert the sliding friction between the connecting tube 61 and the pipe wall into rolling friction, so as to reduce the wear of the clamping mechanism 6 on the pipe wall.

[0035] In the pipeline detection device provided in the present disclosure, the connecting pipe 61 can be movably installed in the installation pipe 13 in any suitable manner. As an exemplary embodiment, refer to Figure 4 As shown in , the clamping mechanism 6 may further include an operating portion 62. The outer wall of the connecting pipe 61 may have a thread for threaded connection with the mounting pipe 13. The operating portion 62 may be provided at one end of the connecting pipe 61 away from the pipeline, so as to operate the connecting pipe 61 to rotate relative to the mounting pipe 13. In this way, when the staff rotates the connecting pipe 61, the connecting pipe 61 will also move relative to the mounting pipe 13 in the radial direction of the pipeline. After the position of the connecting pipe 61 is determined, the thread between the connecting pipe 61 and the mounting pipe 13 can also limit the radial movement of the connecting pipe 61 along the pipeline, which can further improve the assembly stability of the pipeline detection device.

[0036] In the pipeline detection device provided by the present disclosure, the operating part 62 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 4 As shown in , the operating portion 62 can be configured as a sphere, and the surface of the operating portion 62 can be provided with anti-slip grooves 621. Among them, the spherical design can be convenient for the staff to grasp on the one hand, and can save the space occupied by the operating portion 62 on the other hand. In addition, the design of the anti-slip grooves 621 can facilitate the staff to rotate the operating portion 62. In other embodiments, the operating portion 62 can also be configured as other suitable shapes, such as U-shaped, T-shaped, etc., and the present disclosure does not make specific restrictions on this.

[0037] In the pipeline detection device provided by the present disclosure, in order to further improve the clamping effect of the clamping mechanism 6 on the pipeline, as an exemplary embodiment, reference is made to Figure 5 As shown in , the clamping mechanism 6 may also include a first rod 66, a second rod 63 and a first elastic member 65. The first rod 66 may be fixedly connected in the connecting tube 61, one end of the second rod 63 may be movably installed in the connecting tube 61, and the other end may extend out of the connecting tube 61 and be fixed with a ball 64. The two ends of the first elastic member 65 may be fixedly connected to the first rod 66 and the second rod 63, respectively. In this way, the second rod 63 can be tightly pressed against the outer wall of the pipeline under the elastic force of the first elastic member 65 to ensure the clamping effect of the clamping mechanism 6 on the pipeline. In addition, due to the provision of the first elastic member 65, when the pipeline detection device is subjected to external force, the first elastic member 65 can reduce the effect of the external force on the pipeline, so as to prevent the clamping mechanism 6 from damaging the pipeline and protect the pipeline. Among them, the first elastic member 65 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 5 As shown in FIG. 8 , the first elastic member 65 may be configured as a spring.

[0038] In the pipeline detection device provided by the present disclosure, in order to facilitate the movement of the pipeline detection device, as an exemplary embodiment, reference is made to Figure 2 and Figure 6 As shown in , the pipeline detection device may further include at least one traveling mechanism 7, which may be mounted on a mounting frame, and may include a traveling wheel 75, a driving member, and a position adjustment structure, wherein the driving member is used to drive the traveling wheel 75 to rotate, and the position adjustment structure is used to adjust the position of the traveling wheel 75 relative to the mounting frame, so that the traveling wheel 75 abuts against the outer wall of the pipeline. In this way, since the traveling wheel 75 abuts against the outer wall of the pipeline, when the driving member drives the traveling wheel 75 to rotate, the traveling wheel 75 can move with the traveling mechanism 7 relative to the pipeline, and then can move with the pipeline detection device relative to the pipeline, so that the pipeline detection device can detect the pipe wall at different positions.

[0039] In this embodiment, the number of the traveling mechanisms 7 can be two, and the two traveling mechanisms 7 can be symmetrically arranged on opposite sides of the pipe, so that the traveling wheels 75 of the two traveling mechanisms 7 can simultaneously abut on opposite sides of the pipe to prevent the traveling wheels 75 from being separated from the pipe wall due to shaking. Compared with only one traveling mechanism 7, the above design can improve the reliability of the traveling mechanism 7. In other embodiments, the traveling mechanisms 7 can also be designed to be other suitable numbers, and the present disclosure does not make specific restrictions on this.

[0040] The drive member may be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 6As shown in , the driving member can be configured as a first motor 76, and the first motor 76 can be connected to the traveling wheel 75 to drive the traveling wheel 75 to rotate forward or reverse. In this way, by operating the first motor 76 to rotate forward or reverse, the traveling wheel 75 can drive the pipeline detection device to reciprocate relative to the pipeline, thereby saving manpower and eliminating the workload of manually moving the pipeline detection device.

[0041] In the pipeline detection device provided by the present disclosure, the position adjustment structure can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 6 As shown in , the position adjustment structure may include a second motor 71, a gear 72 and an adjustment cylinder 74. The second motor 71 may be mounted on a mounting frame. The output end of the second motor 71 may be connected to the gear 72 in a transmission manner to drive the gear 72 to rotate. The mounting frame may have a through hole. The adjustment cylinder 74 may be movably arranged in the through hole along the radial direction of the pipeline. A rack may be arranged on the side wall of the adjustment cylinder 74, and the gear 72 may be meshed with the rack. In this way, when the second motor 71 drives the gear 72 to rotate, the position of the rack relative to the gear 72 may change, and therefore, the position of the adjustment cylinder 74 relative to the gear 72 may also change. On this basis, since the adjustment cylinder 74 is movably arranged in the through hole along the radial direction of the pipeline, the position of the adjustment cylinder 74 relative to the mounting frame along the radial direction of the pipeline may be changed by operating the second motor 71 to rotate, so that the adjustment cylinder 74 can drive the traveling wheel 75 to press against the outer side wall of the pipeline, thereby ensuring the reliability of the traveling mechanism 7.

[0042] The outer surface of the traveling wheel 75 may be provided with an anti-skid pad 751, so that the friction between the traveling wheel 75 and the pipe wall of the pipe can be increased.

[0043] In the pipeline detection device provided by the present disclosure, in order to further improve the reliability of the traveling mechanism 7, as an exemplary embodiment, reference is made to Figure 7 As shown in , the traveling mechanism 7 may further include a third rod 77, a fourth rod 73, and a second elastic member 78. The third rod 77 may be fixedly connected to the adjusting cylinder 74. One end of the fourth rod 73 may be movably installed in the adjusting cylinder 74, and the other end may extend out of the adjusting cylinder 74 and be installed with a traveling wheel 75. The two ends of the second elastic member 78 may be fixedly connected to the third rod 77 and the fourth rod 73, respectively. In this way, the fourth rod 73 may be tightly pressed against the outer wall of the pipeline under the elastic force of the second elastic member 78. In addition, due to the provision of the second elastic member 78, when the pipeline detection device is subjected to an external force, the second elastic member 78 may reduce the effect of the external force on the pipeline, so as to prevent the traveling mechanism 7 from damaging the pipeline, and thus may protect the pipeline.

[0044] The second elastic member 78 can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 7As shown in , the second elastic member 78 can be constructed as a spring. When the pipeline surface is uneven, the arrangement of the first elastic member 65 and the second elastic member 78 can enable the pipeline detection device to move smoothly on the pipeline to avoid being stuck.

[0045] In the pipeline detection device provided in the present disclosure, the installation of the traveling wheel 75 and the first motor 76 can be realized in any suitable manner. As an exemplary embodiment, refer to Figure 6 and Figure 7 As shown in , a mounting seat may be provided at one end of the fourth rod 73 close to the pipe, the mounting seat may be constructed in a U shape, and may include a first section, a second section, and a third section connected in sequence, the second section is connected to the fourth rod 73, the traveling wheel 75 may be rotatably mounted between the first section and the third section, and the first motor 76 may be mounted on the first section or the third section and be transmission-connected to the traveling wheel 75. In this way, the output end of the first motor 76 can directly pass through the first section or the third section to be transmission-connected to the traveling wheel 75, without the aid of other transmission structures, and the arrangement is simple.

[0046] In the pipeline detection device provided by the present disclosure, in order to facilitate the installation of the pipeline detection device, as an exemplary embodiment, reference is made to Figure 2 and Figure 3 As shown in , the mounting frame may include a first mounting ring 1 and a second mounting ring 2. Both the first mounting ring 1 and the second mounting ring 2 may be semicircular structures, and the two ends of the first mounting ring 1 may be detachably connected to the two ends of the second mounting ring 2. In this way, when using the pipeline detection device, it is only necessary to disassemble the first mounting ring 1 and the second mounting ring 2 and then put them on the position to be detected, and then assemble the first mounting ring 1 and the second mounting ring 2, which is convenient for disassembly and assembly. In this embodiment, the two ends of the first mounting ring 1 may be respectively connected to the two ends of the second mounting ring 2 by bolts 12. In other embodiments, the first mounting ring 1 and the second mounting ring 2 may also be connected by other suitable methods, such as snap-on connection, etc., and the present disclosure does not make specific restrictions on this.

[0047] In the pipeline detection device provided in the present disclosure, the detection mechanism can be constructed in any suitable manner. As an exemplary embodiment, refer to Figure 1 As shown in , the detection mechanism includes: a detector 5, a connecting line 4 and a detection probe 3. The detection probe 3 is installed on a mounting frame for detecting the pipeline. The detection probe 3 is electrically connected to the detector 5 through the connecting line 4. In this way, when the pipeline is at a higher position, the connecting line 4 can facilitate the operator to hold the detector 5, which is convenient for operation. In other embodiments, the detection probe 3 and the detector 5 can also be connected in other suitable ways, such as Bluetooth connection, etc., and the present disclosure does not make specific restrictions on this.

[0048] In summary, when the pipeline detection device provided by the present disclosure is used, it is necessary to first install the first mounting ring 1 and the second mounting ring 2 at the position to be detected on the pipeline by means of the bolts 12, and then rotate the multiple operating parts 62 to make the connecting pipe 61 drive the ball 64 to press against the pipe wall of the pipeline, ensuring that the multiple clamping mechanisms 6 are firmly clamped on the pipeline, and then detect the pipe wall of the pipeline by means of the detection probe 3. After the current position detection is completed, the pipeline detection device is driven by the traveling wheel 75 of the traveling mechanism 7 to move along the axial direction of the pipeline to the next position to be detected, and then the pipeline can be detected by means of the detection probe 3.
