Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically a pipeline CCTV inspection device for marking damage on the outer wall. Background Technology

[0002] In municipal drainage, industrial transportation, and water conservancy projects, pipelines serve as the core transportation carriers. Their long-term stable operation is directly related to project safety and operational efficiency. As pipelines age, they are susceptible to damage such as cracks, corrosion pits, and localized breaks due to factors such as soil electrochemical corrosion, external construction loads, and scouring and abrasion by the transported medium. If these damages are not detected and accurately located and repaired in a timely manner, they may lead to safety accidents such as media leakage and pipeline structure collapse, causing not only economic losses but also potential environmental pollution. Therefore, it is necessary to use a pipeline CCTV detection outer wall damage marking device to conduct pipeline inspection operations.

[0003] However, due to the poor marking adjustment capability of existing pipeline CCTV detection outer wall damage marking devices, it is not convenient to adjust the height of the marking pen according to the marking needs during actual use. It can only mark pipelines at fixed positions and heights, which is not convenient for marking the outer wall of pipelines to a greater extent, thus affecting the ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a pipeline CCTV detection outer wall damage marking device to solve the problem mentioned in the background art that the existing technology is not convenient to adjust the height of the marking pen according to the marking needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline CCTV detection outer wall damage marking device, comprising a CCTV detector body, a first limiting groove being provided on one side of the top of the CCTV detector body, and a marking adjustment mechanism being provided at the top of the CCTV detector body. The marking adjustment mechanism includes a drive motor. The drive motor is fixedly installed on one side of the CCTV detector body. The output shaft of the drive motor is fixedly connected to the transmission screw through a coupling. The transmission screw extends into the interior of the first limiting groove.

[0006] Preferably, a support bearing seat is fixedly installed on the inner wall of the first limiting groove on the side away from the drive motor, the side of the transmission screw away from the drive motor is fixedly connected to the inside of the support bearing seat, and a positioning slider is threadedly installed on the outer end of the transmission screw.

[0007] Preferably, a second limiting groove is provided on one side of the first limiting groove at the top of the CCTV detector body. A guide slide rod is fixedly installed inside the second limiting groove, and a movable slider is sleeved on the outer end of the guide slide rod.

[0008] Preferably, a connecting mounting block is fixedly installed at the top of the positioning slider and the moving slider, an electric push rod is fixedly installed at the top of the connecting mounting block, and a push rod is fixedly installed at the output end of the electric push rod.

[0009] Preferably, a support mounting block is fixedly installed at the top of the push rod, a first mounting tube is fixedly installed on the first side of the support mounting block, a first rubber connecting ring is fixedly installed in the middle of the side of the first mounting tube away from the support mounting block, and a first waterproof marking pen is sleeved inside the first rubber connecting ring.

[0010] Preferably, a second mounting bracket is fixedly installed at the top of the support mounting block, a second rubber connecting ring is fixedly installed at the middle of the top of the second mounting bracket, and a second waterproof marking pen is sleeved inside the second rubber connecting ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This pipeline CCTV detection outer wall damage marking device, through the setting of the marking adjustment mechanism, realizes the adjustment of the distance between the marking component and the pipeline. When the drive motor starts, the transmission screw rotates under the stable support of the support bearing seat, driving the threaded positioning slider to slide smoothly along the first limit groove. At the same time, the moving slider slides synchronously along the guide slide rod, ensuring that there is no offset or shaking during the movement of the connecting mounting block and the marking component above. This design solves the limitation of traditional devices that can only mark pipelines in fixed positions. According to the damage position detected by the CCTV detector body, the marking pen can be quickly moved to the corresponding area, which greatly improves the flexibility and accuracy of the marking position, and facilitates efficient marking of damage at different axial positions on the outer wall of the pipeline. 2. This pipeline CCTV inspection device for marking external wall damage establishes a convenient height adjustment mechanism through the cooperation of an electric push rod and a push rod. When it is necessary to adapt to pipelines of different diameters or installation heights, activating the electric push rod will drive the push rod to move the support mounting block up and down, thereby adjusting the operating height of the first and second waterproof marking pens. Compared with the fixed height design of traditional devices, this structure can flexibly adapt to different height requirements from small industrial pipelines to large municipal drainage pipelines. Height adjustment can be completed without disassembling or replacing parts, making operation simple and quick. This effectively expands the applicability of the device and ensures that cracks, corrosion pits, and other damage at different heights on the pipeline's external wall can be accurately marked, improving the convenience of actual operation. Furthermore, the second waterproof marking pen can mark the top of the inner wall of the pipeline, achieving the function of marking both the inner and outer walls. 3. This pipeline CCTV detection external wall damage marking device, through the combination design of dual marking pens and rubber connecting rings, takes into account both the adaptability and stability of the marking. The support mounting block is respectively equipped with a first mounting pipe bracket and a second mounting pipe bracket, corresponding to the installation of the first waterproof marking pen and the second waterproof marking pen. At the same time, the first and second rubber connecting rings, with their own elasticity, can not only tightly wrap the marking pen to prevent it from loosening and falling off during operation, but also adapt to the installation requirements of marking pens of different diameters. There is no need to replace the fixing parts, which further improves the flexibility and practicality of the device and ensures the continuity and stability of pipeline external wall damage marking operations.

The side of the transmission screw 302 away from the drive motor 301 is fixedly connected to the interior of the support bearing seat 303. A positioning slider 304 is threaded onto the outer end of the transmission screw 302. A second limiting groove 305 is opened on one side of the first limiting groove 2 at the top of the CCTV detector body 1. A guide is fixedly installed inside the second limiting groove 305. A movable slider 307 is sleeved on the outer end of the guide slider 306. A connecting mounting block 308 is fixedly installed on the top of the positioning slider 304 and the movable slider 307. An electric push rod 309 is fixedly installed on the top of the connecting mounting block 308. A push rod 310 is fixedly installed on the output end of the electric push rod 309. The electric push rod 309 pushes the push rod 310 to drive the support mounting block 4 to rise or fall. The drive motor 301 is started to drive the transmission screw 302 to rotate smoothly in the support bearing seat 303. The positioning slider 304 moves axially along the threaded trajectory of the transmission screw 302. At the same time, the movable slider 307 slides synchronously along the guide slider 306. The position distance between the first waterproof marker pen 7 and the outer wall of the pipe can be adjusted.

[0016] A support mounting block 4 is fixedly installed at the top of the push rod 310. A first mounting pipe bracket 5 is fixedly installed on both sides of the support mounting block 4 away from the support mounting block 4. A first rubber connecting ring 6 is fixedly installed in the middle of the side of the first mounting pipe bracket 5 away from the support mounting block 4.

[0017] Working Principle: When using this pipeline CCTV inspection device for external wall damage marking, first connect an external power source to power the electrical components on the device and connect it to the external control system. At the start of operation, the CCTV detector body 1 is activated via the external control system. The CCTV detector body 1 uses the YL-CCTV pipeline robot inspection system, whose built-in high-definition camera module performs a comprehensive scan of the pipeline's external wall, simultaneously transmitting the captured images to the external control terminal in real time. The operator observes the images through the terminal. When damage such as cracks, corrosion pits, or localized breaks are found on the pipeline's external wall, the control system first records the coordinates corresponding to the damage location. Parameters (including axial and height positions) are used as the basis for marking and positioning. If the axial position of the mark needs to be adjusted, the operator sends a start command to the drive motor 301 through the control system. The output shaft of the drive motor 301 drives the transmission screw 302 to rotate smoothly under the limit support of the support bearing seat 303 through the coupling. Since the positioning slider 304 and the transmission screw 302 are connected by a threaded sleeve, the rotation of the transmission screw 302 will drive the positioning slider 304 to move linearly along the first limit groove 2 axially. At the same time, the movable slider 307, which is connected to the top of the positioning slider 304 through the connecting mounting block 308, will slide synchronously along the guide slide rod 306 in the second limit groove 305 to avoid continuous movement. If the mounting block 308 shifts or shakes during movement, ensure that the mounting block 308, the electric push rod 309 above it, and the marking pen assembly move smoothly, bringing the first waterproof marking pen 7 closer to the damaged area on the outer wall of the pipe. At this point, the control system stops the drive motor 301, completing the positioning of the marking axial position. If the height of the marking needs to be adjusted to match the pipe diameter or damage height, the operator sends a lifting command to the electric push rod 309 through the control system. The output end of the electric push rod 309 will push the push rod 310 to extend upward or retract downward, thereby causing the support mounting block 4 at the top of the push rod 310 to rise and fall synchronously. The rising and falling of the support mounting block 4 will drive the first mounting pipes on both sides. The first waterproof marking pen 7 on the frame 5 and the second waterproof marking pen 10 on the top second mounting pipe frame 8 are adjusted in height synchronously until the tip of the first waterproof marking pen 7 is precisely aligned with the damaged location of the pipe. The electric push rod 309 is then raised and lowered, which can drive the first waterproof marking pen 7 to mark the damaged area. The electric push rod 309, drive motor 301 and CCTV detector body 1 are turned off in sequence through the control system to complete a single pipe outer wall damage detection and marking operation. If it is necessary to detect the next damage, the above positioning and marking process can be repeated. The second mounting pipe frame 8 and the second waterproof marking pen 10 make it easy to put the device inside the pipe for marking operations on the top of the inner wall of the pipe.
