Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a pipeline repair and inspection device. Background Technology
[0002] The purpose of pipeline repair is to use various repair techniques to repair underground pipelines that have been damaged or leaked due to long-term use. Before repairing the inner wall of the pipeline, it is necessary to inspect the inner wall of the pipeline to determine the location of the damage.
[0003] In existing technologies, the location of damage to the inner wall of a pipe is mostly determined by using a detection camera connected to a display. In actual operation, the detection camera is fixed to the end of a long rod, and relevant personnel use the long rod to insert the detection camera into the pipe to be repaired. Then, by moving the long rod, the detection camera is continuously moved, thereby achieving continuous imaging of the inner wall of the pipe.
[0004] However, since the movement of the long rod relies entirely on human power, the operation is quite laborious and the detection efficiency is low. In addition, due to the space limitations of the working wells at both ends of the underground pipeline, it is inconvenient to move the long rod from the ground to the inside of the working well and to insert it into the pipeline to be repaired from the working well.
[0005] Therefore, it is necessary to invent a pipeline repair and inspection device to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a pipeline repair and inspection device that can use a repetitive traction mechanism to enable the inspection camera to be inserted into and moved out of the pipeline, saving manpower, making it convenient to use and improving inspection efficiency. In addition, the combination of sliding rod and multiple extension rods can not only ensure the inspection length, but also make it easier to move from the ground to the inside of the working well. This solves the problems mentioned in the background art, which are that the operation is relatively laborious and the inspection efficiency is low because the movement of the long rod relies entirely on manpower. At the same time, the space limitation of the working wells at both ends of the underground pipeline makes it inconvenient to move the long rod from the ground to the inside of the working well and to insert it into the pipeline to be repaired.

[0028] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0033] Figure 5 This is another partial structural schematic diagram of the repetitive traction mechanism 2 of a pipeline repair and inspection device according to one embodiment of the present disclosure.
[0034] like Figures 1-5 As shown, the pipeline repair and inspection device disclosed herein may include components such as: an internal pipe fixing mechanism 1, a repetitive traction mechanism 2, and an inspection mechanism 3.
[0035] like Figure 2As shown in this disclosure, the pipe fixing mechanism 1 includes a fixing plate 11. A support sleeve 12 is fixedly and through the center of the front of the fixing plate 11. The support sleeve 12 is used to guide and support the sliding rod 31 and multiple extension rods 32. Multiple sets of fixing components are evenly fixedly arranged on the front edge of the fixing plate 11. Each set of fixing components includes an extension plate 13 fixedly connected to the fixing plate 11. An electric push rod A14 is fixedly arranged on the inner side of the extension plate 13. The output shaft of the electric push rod A14 slides through the extension plate 13 and is fixedly connected to an arc-shaped support plate 15.
[0036] This allows the fixing plate 11 to be placed inside the pipe to be inspected. Then, the three electric push rods A14 are driven to extend their output shafts in sync. When the output shafts of the electric push rods A14 extend, they drive the arc-shaped support plate 15 to move outward. When the three arc-shaped support plates 15 are all in contact with the inner wall of the pipe, the three electric push rods A14 are stopped, thereby fixing the entire pipe fixing mechanism 1 inside the pipe, which facilitates subsequent inspection operations.
[0037] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the repetitive traction mechanism 2 includes an outer ring 23 with a clearance groove 24 at the top. End plates 22 are fixedly installed on both sides of the outer ring 23. An electric push rod B21 is fixedly connected to the back of one end plate 22 and is fixedly installed on the back of the fixed plate 11. A guide rod 25 is fixedly connected to the back of the other end plate 22. A guide sleeve 26 is slidably sleeved on the outside of the guide rod 25 and is fixedly installed through the front of the fixed plate 11. A U-shaped seat 27 is fixedly installed on the top of any end plate 22. A manual pressure rod 28 is rotatably connected to the inside of the U-shaped seat 27 via a pin. A friction block 29 is fixedly installed at the bottom of the manual pressure rod 28 and is pressed against the top of the adjacent extension rod 32.
[0038] Therefore, after a new extension rod 32 is connected to the front end of the extension rod 32 by rotation, the end of the manual pressure rod 28 is held and pressed down, thereby pressing the friction block 29 against the top of the adjacent extension rod 32. Subsequently, the output shaft of the electric push rod B21 drives the outer ring 23 to move backward continuously through the adjacent end plate 22. During this process, the end plate 22 drives the extension rod 32 to move backward synchronously through the U-shaped seat 27, the manual pressure rod 28, and the friction block 29. When the extension rod 32 moves backward, it pushes the new extension rod 32 backward. The traction mechanism simultaneously pushes the sliding rod 31, causing it to move the extension rod 32 deeper into the pipe. Once the outer ring 23 contacts the support sleeve 12, the manual pressure rod 28 is released, and the electric push rod B21 moves the outer ring 23 forward and resets it via the adjacent end plate 22. This process is repeated multiple times until the pipe inspection is completed. Compared to existing technologies, the repeated traction mechanism 2 can be used to move the inspection camera 33 deeper and further into the pipe, saving manpower and providing greater ease of use while increasing inspection efficiency.
[0039] like Figure 2 and Figure 3 As shown in this disclosure, the detection mechanism 3 includes a sliding rod 31 slidably disposed inside the support sleeve 12. A detection camera 33 connected to a display screen is fixedly disposed at the rear end of the sliding rod 31. It should be noted that the detection camera 33 is prior art, so its specific working principle will not be described in detail here. The detection mechanism 3 also includes multiple extension rods 32. The front end of the sliding rod 31 and the front end of the extension rod 32 are both provided with threaded grooves. A threaded post is fixedly disposed at the rear end of the extension rod 32. The threaded groove and the threaded post are adapted to each other.
[0040] This allows the sliding rod 31 and the extension rod 32 to be connected through the threaded groove and the threaded column. At the same time, multiple extension rods 32 can also be connected through the threaded groove and the threaded column, thereby ensuring the movement distance of the detection camera 33 in the pipeline and making it easier to move from the ground to the inside of the working well.
[0041] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0042] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
