Description

Technical Field

[0001] This utility model relates to the field of water pipeline inspection technology, and in particular to a vision device for inspecting buried steel water pipelines. Background Technology

[0002] In urban water supply and drainage, industrial water transmission, and long-distance inter-regional water transfer projects, buried steel water pipelines serve as the core transport carriers. They are located in complex underground environments for extended periods, making them prone to defects such as internal scaling, corrosion perforation, weld cracking, and foreign object intrusion. These defects not only affect water transmission efficiency and water quality safety but may also lead to safety accidents such as road collapses. Traditional manual excavation and inspection methods are costly, inefficient, and cause significant disruption to traffic and the environment. This device is mainly used in the municipal water supply and drainage industry, petrochemical industry, water conservancy engineering industry, and industrial and mining enterprises. Vision devices for water pipeline inspection typically consist of three core components: first, a mobile carrier module, usually a waterproof and pressure-resistant tracked or wheeled robot equipped with a drive motor and guidance system, capable of adapting to the curved and narrow spaces inside the pipeline and achieving autonomous or remote control movement; second, a vision acquisition module, consisting of a high-definition industrial camera, which can clearly capture details of the inner wall of the pipeline in dark and humid conditions; and third, a data transmission and processing module, including a wireless transmission unit, a data storage unit, and an edge computing chip, which can transmit the acquired image and video data to the ground terminal in real time and perform preliminary identification and marking of suspected defects. Most visual devices for water pipeline inspection on the market often lack an important component: a mirror cleaning device. This means that when these devices encounter sewage during pipeline inspection, the presence of sewage may contaminate the mirror of the inspection device. This contamination may affect the device's line of sight and thus the accuracy of the inspection results. Therefore, a visual device for the inspection of buried steel water pipelines is proposed to solve the above problems. Utility Model Content

[0016] 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.

[0017] Reference Figures 1-3This utility model provides an embodiment including a bracket 12, which serves as the basic support structure for the entire device, providing a stable mounting platform for various components. A rotating shaft 14 is rotatably connected to the inner side of the bracket 12, allowing it to rotate flexibly around its own axis to provide power transmission for subsequent cable winding. A winding drum 13 is fixedly connected to the outer side of the rotating shaft 14, rotating synchronously with the rotating shaft 14 to achieve the winding and unwinding operation of the safety rope 9. The safety rope 9 is wound around the outer side of the winding drum 13, connecting it to the subsequent detection components and acting as a traction device for the detection components. The bracket 12 has support rods 11 fixedly connected to both sides. These support rods 11 extend outwards from both sides of the bracket 12, providing extended support points for subsequent installation of components such as the slider 17. A connecting frame 10 is fixedly connected to the right side of each support rod 11. The connecting frame 10 serves as the mounting carrier for the slider 17, providing a stable framework for its sliding. The slider 17 is installed inside the connecting frame 10, allowing it to move along a specific trajectory for position adjustment. A spring 18 is installed inside the slider 17, possessing elastic extension and retraction capabilities, which buffers and resets the slider 17 between it and the connecting block 20. The function of the slider 17 is to slide a connecting block 20 on its inner side. The connecting block 20 can slide inside the slider 17, thereby driving the support block 21 to adjust its position. The bottom of the connecting block 20 is fixedly connected to the support block 21, which is used to install the brush 19 and also plays a certain role in limiting and guiding the safety rope 9. The brush 19 is fixedly connected to the inner wall of the support block 21. The brush 19 can contact the surface of the safety rope 9 and clean the impurities attached to its surface during the winding and unwinding process. The end of the safety rope 9 away from the winding drum 13 is fixedly connected to a locking sleeve 8. The locking sleeve 8 and the locking head 7 cooperate with each other to realize the connection between the safety rope 9 and the control. The detachable connection between blocks 3 includes a lock head 7 inside the lock sleeve 8, which can be inserted into the lock sleeve 8 to lock and ensure the stability of the connection. A control block 3 is fixedly connected to the right side of the lock head 7. The control block 3 can regulate the working status of components such as the camera 4. At the same time, as an intermediate structure connecting the lock head 7 and the camera 4, the control block 3 is fixedly connected to the right side of the camera 4. The camera 4 is the core image acquisition component in the detection process, which can capture the image information inside the pipeline. A fixing plate 5 is fixedly connected to the top of the camera 4. The fixing plate 5 provides an installation position for components such as the motor 6, and also provides a certain degree of protection for the top of the camera 4.

[0018] Reference Figures 1-3A motor 6 is fixedly connected to the left side of the fixed plate 5. The motor 6 serves as the power output source, driving the second fixed pin 23 to rotate. The output end of the motor 6 is fixedly connected to the second fixed pin 23, which rotates around its own axis under the drive of the motor 6, thereby driving the first connecting rod 24 to move. The first connecting rod 24 is fixedly connected to the outer side of the second fixed pin 23. The angle of the first connecting rod 24 changes with the rotation of the second fixed pin 23, thus transmitting power to the second connecting rod 25. The end of the first connecting rod 24 furthest from the second fixed pin 23 is rotatably connected to the second connecting rod 25. The second connecting rod 25 moves under the drive of the first connecting rod 24, further transmitting power. The power is transmitted sequentially to the connecting rod 25, which is rotatably connected to the end of the connecting rod 25 away from the connecting rod 1 24. Under the action of the connecting rod 25, the connecting rod 26 rotates around the fixing pin 1 22, thereby driving the brush 27 to adjust its position. The fixing pin 1 22 is rotatably connected to the inner side of the connecting rod 26, providing a fixed fulcrum for the rotation of the connecting rod 26 and ensuring the stability of the rotation process. The brush 27 is fixedly connected to the outer side of the connecting rod 26. The brush 27 can clean the mirror surface of the camera 4 under the action of the connecting rod 26, so that the camera 4 can capture images more clearly.

[0019] Reference Figures 1-3 A handle 15 is fixedly connected inside the rotating shaft 14. The handle 15 allows the operator to manually rotate the rotating shaft 14, thereby controlling the winding drum 13 to wind up and unwind the safety rope 9. The support block 21 is installed inside the slider 17, so that the support block 21 can adjust its position as the slider 17 moves, better cooperating with the winding up and unwinding of the safety rope 9 and the cleaning work.

[0020] Reference Figures 1-3 The bottom of the control block 3 is fixedly connected to the support plate 1. The support plate 1 provides the mounting base for the wheel 2 and also supports the bottom of the control block 3. The support plate 1 is rotatably connected to the wheel 2 on both sides. The wheel 2 can roll inside the pipeline, driving the entire detection component to move inside the pipeline, which facilitates detection at different positions of the pipeline.

[0021] Reference Figures 1-3 The inner side of the connecting frame 10 is provided with a slide groove 16. The slide groove 16 provides a specific trajectory for the sliding of the slider 17, ensuring that the slider 17 can only move along the direction of the slide groove 16 and preventing the slider 17 from deviating. The slider 17 is slidably connected to the inner side of the slide groove 16, so that the slider 17 can slide stably along the slide groove 16, thereby driving the connecting block 20 and the support block 21 to adjust their positions.

[0022] Reference Figures 1-3One end of the spring 18 is fixedly connected to the inner wall of the slider 17, and the other end of the spring 18 is fixedly connected to the outer side of the connecting block 20. This connection method allows the spring 18 to extend and retract when the slider 17 and the connecting block 20 move relative to each other, thereby buffering the relative movement between the two. At the same time, it can drive the connecting block 20 to reset after the external force disappears.

[0023] Reference Figures 1-3 Fixed pin 23 is rotatably connected to the inside of fixed plate 5. Fixed plate 5 provides support for the rotation of fixed pin 23, ensuring that fixed pin 23 will not shift its position during rotation. Fixed pin 1 22 is rotatably connected to the inside of fixed plate 5. Fixed plate 5 also provides stable support for fixed pin 1 22, ensuring the stability of fixed pin 1 22 as the fulcrum for the rotation of connecting rod 3 26.

[0024] Reference Figures 1-3 The safety rope 9 is set inside the support block 21, so that the support block 21 can limit the safety rope 9 and ensure that the safety rope 9 always moves within a specific range during the winding and unwinding process. At the same time, it is convenient for the brush 19 to thoroughly clean the surface of the safety rope 9.

[0025] Working principle: When using this device to inspect buried steel water pipelines, the operator first rotates handle 15, causing the rotating shaft 14 to rotate inside the support 12. The winding drum 13 rotates synchronously, thereby enabling the winding and unwinding of the safety rope 9 wound on its outer side. Simultaneously, the safety rope 9 is located inside the support block 21. During the winding and unwinding process, the spring 18 can buffer and reset the relative movement of the connecting block 20 and the slider 17 through elastic extension and contraction. The brush 19, fixedly connected to the inner wall of the support block 21, contacts the surface of the safety rope 9, removing impurities adhering to the surface of the safety rope 9. During cleaning, a locking sleeve 8 is fixedly connected to one end of the take-up roller 13. The locking head 7 cooperates with the locking sleeve 8 to achieve a stable connection. The fixing plate 5 fixedly connected to the top of the camera 4 provides installation support for the motor 6 fixed on the left. After the motor 6 starts, it drives the fixing pin 23 to rotate inside the fixing plate 5. The fixing pin 23 drives the connecting rod 24 to rotate with it, which in turn drives the connecting rod 25 to move. The connecting rod 3 26 rotates around the fixing pin 22 under the drive of the connecting rod 25. The brush 27 adjusts its position accordingly to clean the mirror surface of the camera 4, ensuring that the camera 4 can clearly capture the internal image of the pipeline.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
