Description
Technical Field
[0001] This utility model relates to the field of maintenance devices, and in particular to a pipeline leakage monitoring and maintenance device. Background Technology
[0002] Chinese Patent No. CN202320510014.2 discloses a pipeline leakage monitoring and maintenance device, including a main body, a walking mechanism for driving the main body, a system control center, and a power supply. The main body is equipped with a monitoring mechanism and a repair mechanism. The system control center is communicatively connected to the monitoring mechanism, the repair mechanism, and the walking mechanism. A rotating mechanism is provided between the main body and the monitoring mechanism, and between the main body and the repair mechanism. The rotating mechanism drives the monitoring mechanism and the repair mechanism to rotate and adjust their angles. The repair mechanism includes a nozzle and a grinding head.
[0003] As can be seen from the above, it can monitor pipelines in all directions, accurately locate internal damage points, and automatically repair cracks in pipelines, thereby reducing pipeline maintenance costs. Due to the existence of adjustable telescopic drive wheels and telescopic descaling devices, it can be used for cleaning and maintenance of pipe walls in various diameter and variable diameter pipelines. However, this case also has the following shortcomings: when monitoring and maintaining pipeline leaks, it is often encountered that the pipes being processed are of inconsistent sizes and specifications. When pipes of different specifications are spliced together, there is a conical connection at the pipe joint. In this case, the device is very likely to get stuck inside the pipe.
[0004] Therefore, a pipeline leakage monitoring and maintenance device is proposed to overcome the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a pipeline leakage monitoring and maintenance device, which effectively overcomes the defects of the prior art.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] A pipeline leak monitoring and maintenance device includes a maintenance device and an in-pipe floating walking mechanism. A first camera device is installed at one end of the in-pipe floating walking mechanism, and the maintenance device is installed at the other end of the in-pipe floating walking mechanism.

The first camera device is mounted on one end of the fixed rod, and the maintenance device is mounted on the upper... At the other end of the fixed rod, the floating travel assembly includes a first movable arm, a mounting beam, a second movable arm, a linkage arm, and a roller travel assembly.

The mounting beam is parallel to the fixed rod, and the first and second movable arms are parallel to each other. One end of the linkage arm is hinged to the second movable collar, and the other end of the linkage arm is hinged to the middle of the second movable arm. The roller travel assembly is mounted on the mounting beam.
[0011] Furthermore, the aforementioned roller traveling assembly includes a transmission wheel, a transmission belt, a linkage wheel, and a rotary drive device. The transmission wheel and the linkage wheel are respectively mounted on the two ends of the mounting beam away from the fixed rod via wheel frames that are rotatably assembled with them.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0027] Example
[0028] like Figure 1 , 2 As shown in Figure 3, the pipeline leakage monitoring and maintenance device of this embodiment includes a maintenance device 1 and an in-pipe floating walking mechanism 2. One end of the in-pipe floating walking mechanism 2 is equipped with a first camera device 25, and the maintenance device 1 is installed at the other end of the in-pipe floating walking mechanism 2.
[0029] In this embodiment, the pipeline leak monitoring and maintenance device is placed inside the pipeline to be inspected and repaired. The floating walking mechanism 2 inside the pipe contacts the pipe wall and automatically moves along the pipeline after activation. A cable connecting to the electrical components in the device is attached to the other end of the floating walking mechanism 2 in the direction of travel. When encountering unevenness in the inner wall of the pipeline (such as protrusions or obstacles), the floating walking mechanism 2 can adaptively float radially, thus smoothly overcoming obstacles without getting stuck. Simultaneously, the first camera device 25 transmits the captured images to a smart terminal connected outside the pipeline via a cable. The smart terminal controls the movement and stopping of the floating walking mechanism 2 and controls the maintenance device 1 to repair the leaks detected by the first camera device 25. Overall, the structure is reasonably designed. The floating walking mechanism improves the passability within the pipeline, making it less prone to getting stuck. Furthermore, the combined effect of the first camera's image capture allows for timely detection of pipeline leaks, which can then be repaired using the maintenance device.
[0030] In this embodiment, the first camera device 25 adopts a compatible spherical camera with a wide shooting angle.
[0031] As a preferred implementation method, such as Figure 1 , 2As shown in Figures 1 and 3, the aforementioned floating walking mechanism 2 includes a fixed rod 21, a first movable collar 22, a second movable collar 23, a fixed collar 24, and multiple sets of floating walking components. The fixed collar 24 is fixedly sleeved on the fixed rod 21. The first movable collar 22 and the second movable collar 23 are respectively movably sleeved on the fixed rod 21. The first movable collar 22, the second movable collar 23, and the fixed collar 24 are spaced apart from one end of the fixed rod 21. An elastic element 31 connects the first movable collar 22 and the second movable collar 23. The multiple sets of floating walking components are equally spaced along the circumference of the fixed rod 21. The first camera device 25 is mounted on one end of the fixed rod 21, and the maintenance device 1 is mounted on the upper... At the other end of the fixed rod 21, the floating walking assembly includes a first movable arm 26, a mounting beam 27, a second movable arm 28, a linkage arm 29, and a roller walking assembly. One end of the first movable arm 26 is hinged to the first movable collar 22, and one end of the second movable arm 28 is hinged to the fixed collar 24. Both ends of the mounting beam 27 are respectively hinged to the other ends of the first movable arm 26 and the second movable arm 28. The mounting beam 27 is parallel to the fixed rod 21, and the first movable arm 26 and the second movable arm 28 are parallel. One end of the linkage arm 29 is hinged to the second movable collar 23, and the other end of the linkage arm 29 is hinged to the middle of the second movable arm 28. The roller walking assembly is mounted on the mounting beam 27.
[0032] In the above implementation scheme, during the walking process, the elastic element 31 will always apply elastic force to the first movable collar 22 and the second movable collar 23 along the axial direction of the fixed rod 21. This elastic force will keep the other ends of the first movable arm 26 and the second movable arm 28 as far away from the fixed rod 21 as possible. That is, it will keep the mounting beam 27 away from the fixed rod 21, so that the roller walking assembly is elastically "pressed" against the inner wall of the pipe. This allows multiple sets of roller walking assemblies to walk close to the inner wall of the pipe. Furthermore, when encountering protruding obstacles, the mounting beam 27 is subjected to radial pressure, which can compress the elastic element 31, thereby achieving a floating fit between the roller walking assembly and the pipe wall. Thus, when encountering protrusions in the pipe wall, it can adaptively float elastically, thereby smoothly crossing the protrusion and improving the passability of the walking.
[0033] As a preferred implementation method, such as Figure 3As shown, the roller traveling assembly includes a transmission wheel 35, a transmission belt 36, a linkage wheel 37, and a rotary drive device. The transmission wheel 35 and the linkage wheel 37 are respectively mounted on the two ends of the mounting beam 27 away from the fixed rod 21 via wheel frames that are rotatably assembled with them. The transmission belt 36 is wrapped around the transmission wheel 35 and the linkage wheel 37. The rotary drive device is mounted on the mounting beam 27 and is connected to the transmission wheel 35 for driving the transmission wheel 35 to rotate.
[0034] In the above implementation scheme, the rotary drive device drives the transmission wheel 35 to rotate, thereby driving the linkage wheel 37 to rotate synchronously through the transmission belt 36, so that the transmission wheel 35 and the linkage wheel 37 can roll along the inner wall of the pipe. The transmission structure is ingeniously designed.
[0035] As a preferred implementation method, such as Figure 4 As shown, the rotary drive device includes a stepper motor 32, a transmission bevel gear 33, and a fixed bevel gear 34. The stepper motor 32 is mounted on the mounting beam 27. The transmission bevel gear 33 is coaxially mounted on the motor shaft of the stepper motor 32. The fixed bevel gear 34 is coaxially mounted on the central shaft of the transmission wheel 35. The transmission bevel gear 33 and the fixed bevel gear 34 mesh with each other.
[0036] In the above implementation scheme, the stepper motor 32 drives the meshing transmission bevel gear 33 and fixed bevel gear 34 to move together, thereby driving the transmission wheel 35, transmission belt 36 and linkage wheel 37 to move together, so as to achieve stable rolling movement along the pipe wall and the transmission is relatively stable.
[0037] In this embodiment, the aforementioned floating walking assembly is provided in three sets. The three sets of floating walking assemblies enable the entire device to cooperate with the pipe wall in three directions, achieving stable movement.
[0038] As a preferred implementation method, such as Figure 1 , 2 As shown in Figure 5, the maintenance device 1 includes a rotary drive mechanism 11, a rotary shaft 12, a second camera 13, a fixing plate 14, and a spray repair device 15. The rotary drive mechanism 11 is mounted on the other end of the fixing rod 21. The rotary shaft 12 is coaxially distributed with the fixing rod 21. One end of the rotary shaft 12 is connected to the rotary drive mechanism 11. The second camera 13 is mounted on the other end of the rotary shaft 12. The fixing plate 14 is mounted on the side of the second camera 13 away from the rotary shaft 12. The spray repair device 15 is mounted on the fixing plate 14. The second camera 13 is used to photograph the inner wall of the pipe, and the spray repair device 15 is used to spray repair on the leaks in the inner wall of the pipe.
[0039] In the above implementation scheme, the first camera device 25 captures the approximate location of the leak in the inner wall of the pipe. Then, the floating walking mechanism 2 moves inside the pipe, allowing the maintenance device 1 to reach the location of the leak. Afterward, the rotation drive mechanism 11 drives the second camera 13 to rotate, enabling the second camera 13 to accurately capture the leak. Then, the spray repair device 15 is used to accurately spray repair the leak. The design is very reasonable, and under the guidance of an external intelligent terminal (including existing machine vision technology), the automated and accurate repair operation of the pipe leak is realized.
[0040] In this embodiment, the rotary drive mechanism 11 adopts a servo motor of an appropriate model.
[0041] In this embodiment, the spray repair device 15 uses a repair spray gun that is perpendicular to the fixing rod 21. This repair spray gun is a commercially available product, and its specific structure and principle will not be described in detail here.
[0042] In this embodiment, the elastic element 31 is a spring fitted onto the fixed rod 21, and the two ends of the spring are respectively connected to the first movable collar 22 and the second movable collar 23.
