Description

Technical Field

[0001] This utility model relates to the field of pipeline internal inspection technology, specifically a mechanical guide device for preventing entanglement of pipeline internal inspection probes. Background Technology

[0002] The development of pipeline internal inspection technology originated from the use of pipelines in energy transmission and other fields to detect safety hazards caused by pipeline aging. As pipelines are used for longer periods, corrosion and stress can lead to various defects inside the pipeline, such as cracks and corrosion pits. These defects may cause pipeline rupture accidents, resulting in serious economic losses and environmental pollution. Therefore, regular pipeline inspection is necessary.

[0003] Traditional pipeline inspection devices typically involve a trolley driving into the pipeline to inspect its interior. However, since pipeline diameters vary, the transmission inspection device is generally not compatible with pipelines of different sizes, reducing its practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanical guide device for preventing the entanglement of pipe internal inspection probes. This solves the problem that traditional pipe internal inspection devices typically use a trolley to drive into the pipe to inspect its interior. However, pipes have different inner diameters, and the transmission inspection device generally cannot be matched with pipes of different sizes, thus reducing the device's practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical guide device for preventing entanglement of a pipeline inspection probe, comprising a device body, a video probe disposed at the center of the front end of the device body, a connecting end disposed at the center of the rear end of the device body, a connecting wire being connected through one end of the connecting end, and one end of the connecting wire being electrically connected to the inner wall of one side of the device body, three equidistant rotating grooves being formed on the outer surface of the device body near the front end along the circumferential direction, and three equidistant sliding grooves being formed on the outer surface of the device body near the rear end along the circumferential direction, further comprising:

[0007] The telescopic support is provided in three parts. All three telescopic supports are movably sleeved inside the tilting groove by means of a fixed rod. The telescopic supports are used to fit against the inner wall of the pipe and drive the entire equipment to move.

[0008] Preferably, the three limiting adjustment components include three limiting slide rods, all of which are equidistantly arranged between the inner walls of both sides of the device body along the circumferential direction.

[0009] Preferably, a first tension spring is fitted on the outer surface of each of the three limiting slide rods at the same end, and one end of the first tension spring is fixedly welded to the inner wall of one side of the device body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Example 1:

[0024] Please see Figure 1-3 A mechanical guiding device for preventing entanglement of a pipeline inspection probe includes a device body 1. A video probe 2 is disposed at the center of the front end of the device body 1, and a connecting end 3 is disposed at the center of the rear end of the device body 1. A connecting wire 4 is connected through one end of the connecting end 3, and one end of the connecting wire 4 is electrically connected to the inner wall of one side of the device body 1. Three rotating grooves 5 are equidistantly formed along the circumferential direction on the outer surface of the device body 1 near the front end, and three sliding grooves 6 are equidistantly formed along the circumferential direction on the outer surface of the device body 1 near the rear end. The device body 1 also includes:

[0025] Limit adjustment components 7, three in total, are provided. The three limit adjustment components 7 are equidistantly arranged between the inner walls of both sides of the device body 1 along the circumferential direction. The limit adjustment components 7 are used to adjust the expansion range of the telescopic bracket 8.

[0026] Telescopic brackets 8, three telescopic brackets 8 are provided in total. All three telescopic brackets 8 are movably sleeved inside the tilting groove 5 by a fixed rod. The telescopic brackets 8 are used to fit against the inner wall of the pipe and drive the entire equipment to move.

[0027] In this embodiment, the video probe 2 can be used to capture and detect the inside of the pipe. The connecting end 3 can be used to fix and limit the connecting line 4. When the connecting line 4 is connected to the power supply, it can provide power to the video probe 2. The opening of the flip groove 5 can provide space for the first support rod 81 to move and adjust.

[0028] The three limit adjustment components 7 include three limit slide rods 71. The three limit slide rods 71 ​​are equidistantly arranged between the inner walls of both sides of the device body 1 along the circumferential direction. The outer surfaces of the three limit slide rods 71 ​​are each fitted with a first tension spring 72 near the same end. One end of the first tension spring 72 is fixedly welded to one side of the inner wall of the device body 1. The outer surfaces of the three limit slide rods 71 ​​are each slidably fitted with a first connecting frame 73 near the other end. The first connecting frame 73 is fixedly welded to the other end of the first tension spring 72, and the first connecting frame 73 is slidably limited to the slide groove 6.

[0029] In this embodiment, through the movable connection between the first connecting frame 73 and the second support rod 84 and the sliding arrangement with the limiting slide rod 71, when the first connecting frame 73 slides to one side, it can drive the first tension spring 72 to stretch outward, and cause one end of the second support rod 84 to slide to one side, thereby causing the first support rod 81 to press down.

[0030] Example 2:

[0031] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: the three telescopic supports 8 include three first support rods 81, all three first support rods 81 are movably sleeved inside the flip groove 5 through fixed rods, one end of each of the three first support rods 81 is rotatably provided with a first roller group 82, the inner wall of the opposite side of the three first support rods 81 is fixedly welded with a second connecting frame 83, the interior of each of the three second connecting frames 83 is movably provided with a second support rod 84, and the same end of each of the three second support rods 84 is rotatably connected to the first connecting frame 73;

[0032] A third connecting frame 85 is fixedly welded to the outside of each of the three first support rods 81. A third support rod 86 is movably installed inside each of the three third connecting frames 85. A second roller group 87 is rotatably installed at the same end of each of the three third support rods 86. A second tension spring 88 is fixedly welded between each third support rod 86 and each first support rod 81.

[0033] In this embodiment, the third connecting frame 85 and the third support rod 86 are movably connected. The second tension spring 88 provides elasticity, allowing the third support rod 86 to flip and approach the first support rod 81 when not in use, providing a certain traction force. The rotation of the second roller group 87 and the third support rod 86, as well as the rotation of the first support rod 81 and the first roller group 82, allows the entire detection device to move inside the pipeline.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] When in operation, the three third support rods 86 are first turned and flipped towards the pipe opening. When all three third support rods 86 are inserted into the pipe, the entire detection device is inserted into the pipe. In order to match the size of the pipe and through the inward retraction force of the first tension spring 72, the first connecting frame 73 is driven to slide inward and retract, and the second support rod 84 is driven to retract inward. This causes the three first support rods 81 to simultaneously unfold outward at the end where the first roller group 82 is located, so that the first roller group 82 fits against the pipe.

[0036] Similarly, the inward pulling force of the second tension spring 88 can drive the three third support rods 86 to simultaneously unfold outward at the end where the second roller group 87 is located, so that the second roller group 87 fits against the inner wall of the pipe, thereby allowing the entire device to slide smoothly inside the pipe, which is convenient for subsequent detection work.
