Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically to an intelligent pipeline defect repair device. Background Technology

[0002] In today's industrial sector, pipeline systems are widely used in numerous industries such as petroleum, chemical, natural gas, and water supply, serving as crucial infrastructure for transporting various media. However, with prolonged use and exposure to complex environmental factors, pipelines inevitably develop defects such as cracks, holes, and corrosion. If these defects are not repaired promptly, they can potentially lead to serious accidents such as media leaks and pipeline ruptures, causing not only enormous economic losses but also posing a serious threat to the environment and personal safety.

[0003] During pipeline repair, inspections are conducted using cameras. Optical imaging principles are employed to clearly capture images of the pipeline's inner wall and transmit them to an image acquisition and processing system. Image recognition technology is used to analyze the images, thereby identifying defects. The images are transmitted in real time to an image acquisition card and converted into digital signals for storage in a computer. Then, image recognition algorithms are used to process and analyze the images, such as edge detection and feature extraction, to identify defects such as cracks, holes, and corrosion areas on the pipeline's inner wall.

[0004] In the inspection stage, most devices have limited detection functions, often only able to inspect a portion of the pipe surface, making it difficult to achieve comprehensive, blind-spot-free inspection. This leads to the easy omission of some hidden minor defects, failing to detect potential safety hazards in a timely manner. In the repair stage, existing repair devices and inspection equipment are usually independent of each other. When a pipe defect is detected, the inspection equipment needs to be removed and the repair equipment reinstalled, which is quite cumbersome. Finally, in terms of pipe fixing and support, traditional devices cannot provide stable and reliable support for pipes of different diameters and lengths. Pipes are prone to shaking or rolling during the repair process, affecting the accuracy and stability of the repair operation. Therefore, this utility model provides an intelligent pipe defect repair device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent pipeline defect repair device. It solves the problems of limited detection capabilities in the inspection stage, where most devices only inspect a portion of the pipeline surface, failing to provide comprehensive, blind-spot-free inspection. This leads to the easy omission of hidden, minute defects and the inability to promptly detect potential safety hazards. In the repair stage, existing repair devices and inspection equipment are usually independent. Once a pipeline defect is detected, the inspection equipment must be removed and the repair equipment reinstalled, which is cumbersome. Finally, regarding pipeline fixation and support, traditional devices struggle to provide stable and reliable support for pipelines of different diameters and lengths. Pipelines are prone to shaking or rolling during repair, affecting the accuracy and stability of the repair operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent pipeline defect repair device, comprising a mounting base, wherein the mounting base is provided with a processing mechanism for pipeline defect repair, the processing mechanism comprising:

[0007] The mounting assembly includes a support frame connected to the upper surface of the mounting base via an opening and closing assembly. The upper end of the support frame has a V-shaped groove. A mounting bracket is fixed to the side wall of the support frame. A pressure ring connected to the mounting bracket via a lifting assembly is provided inside the mounting bracket.

[0008] The rotating assembly includes a slide rail bracket fixed to one side of the mounting base. The slide rail bracket has an L-shaped bracket connected by a threaded assembly inside. The lower end of the L-shaped bracket has a connecting ring connected by a gear assembly.

[0009] Preferably, the opening and closing assembly includes a sliding groove formed on the upper surface of the mounting base, a bidirectional screw is rotatably connected to the sliding groove in the horizontal direction, the lower end of the support frame is slidably connected to the inner wall of the sliding groove, and the support frame is threadedly connected to the bidirectional screw.

[0010] Preferably, the lifting assembly includes a pair of telescopic sleeve rods that are fixedly fixed inside the mounting bracket, the lower pressure ring is fixedly connected to the telescopic end of the telescopic sleeve rod, and the upper end of the lower pressure ring is rotatably connected to a first lead screw, which is threadedly connected to the mounting bracket.

[0011] Preferably, the mounting base has positioning grooves on both sides, and the lower end of the support frame is slidably connected to the positioning grooves.

[0012] Preferably, the threaded assembly includes a second lead screw rotatably connected inside the slide rail bracket, the lower end of the L-shaped bracket is slidably connected to the inner wall of the slide rail bracket, and the second lead screw is threadedly connected to the L-shaped bracket.

[0013] Preferably, the gear assembly includes a mounting block fixed at the lower end of an L-shaped bracket, a fixing ring fixed to the inner wall of the mounting block, a connecting ring located on the inner wall of the fixing ring in a rotatable connection, a transmission gear rotatably connected through the horizontal direction of the mounting block, toothed blocks uniformly fixed to the outer wall of the connecting ring for meshing with the transmission gear, six sets of cameras provided on the inner wall of the connecting ring, an electric push rod fixed to the side wall of the connecting ring, and a welding gun fixed to the telescopic end of the electric push rod.

[0014] Beneficial effects

[0015] This invention provides an intelligent pipeline defect repair device. Compared with the prior art, it has the following advantages:

[0016] Firstly, the rotation of the transmission gear in this invention causes the connecting ring to rotate circumferentially within the fixed ring. The six cameras on the inner wall of the connecting ring rotate accordingly, enabling comprehensive image acquisition of the pipeline. This allows for faster and more complete detection of various defects on the pipeline surface, improving detection efficiency and accuracy. When a camera detects a pipeline defect, it activates an electric push rod. The telescopic end of the electric push rod pushes the welding gun towards the defect. By controlling the telescopic range of the electric push rod, the welding gun precisely reaches the repair position for welding repair. This device integrates the detection camera and repair welding gun functions on the same unit. The coordinated operation of the connecting ring, gear assembly, and electric push rod allows for immediate repair after defect detection, eliminating the need to replace equipment or readjust positions. This significantly shortens pipeline repair time, improves work efficiency, simplifies the operation process, and reduces manual operation costs.

[0017] Secondly, when the bidirectional screw of this utility model rotates, the two support frames slide towards or away from each other in the horizontal direction along the sliding groove to achieve the opening and closing action. This can adapt to pipes of different lengths, improve the versatility of the device, and reduce the need to replace different equipment due to different pipe diameters. Then, the V-shaped groove opened at the upper end of the support frame is used to place the pipe, which can better fit the contour of the circular pipe, making the pipe less prone to shaking or rolling. There is no need for special design or frequent adjustment for pipes of different diameters, which improves the compatibility with pipes of various diameters and greatly enhances the versatility and applicability of the device. Finally, the first screw is rotated. Because the first screw is threadedly connected to the mounting bracket, and the lower pressure ring is rotatably connected to the lower end of the first screw and fixedly connected to the telescopic end of the telescopic sleeve, as the first screw rotates, the lower pressure ring will move up and down along the axial direction of the telescopic sleeve under the guidance of the telescopic sleeve, pressing and clamping the pipe to ensure the accuracy and stability of the repair operation.

[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution: an intelligent pipeline defect repair device, including a mounting base 1, on which a processing mechanism for pipeline defect repair is provided, the processing mechanism including:

[0025] The mounting components include a support frame 202 connected to the upper end of the mounting base 1 via an opening and closing component. The upper end of the support frame 202 has a V-shaped groove. The side wall of the support frame 202 is fixed with a mounting bracket 203. The interior of the mounting bracket 203 is provided with a pressure ring 206 connected via a lifting component.

[0026] The rotating assembly includes a slide rail bracket 3 fixed to one side of the mounting base 1. The slide rail bracket 3 has an L-shaped bracket 302 connected by a threaded assembly inside. The lower end of the L-shaped bracket 302 has a connecting ring 401 connected by a gear assembly.

[0027] In a preferred embodiment, the opening and closing assembly includes a groove 2 formed on the upper surface of the mounting base 1. A bidirectional screw 201 is rotatably connected to the groove 2 in the horizontal direction. The lower end of the support frame 202 is slidably connected to the inner wall of the groove 2. The support frame 202 is threadedly connected to the bidirectional screw 201. The lifting assembly includes a pair of telescopic sleeves 205 fixedly inserted inside the mounting bracket 203. A lower pressure ring 206 is fixedly connected to the telescopic end of the telescopic sleeves 205. A first lead screw 207 is rotatably connected to the upper end of the lower pressure ring 206. The first lead screw 207 is threadedly connected to the mounting bracket 203. Positioning grooves 204 are formed on both sides of the mounting base 1. The lower end of the support frame 202 is slidably connected to the positioning grooves 204. The positioning grooves 204 limit and guide the support frame 202. Combined with the groove 2 and the bidirectional screw 201, the support frame 202 remains stable during the opening and closing process, further enhancing the overall stability and reliability of the device.

[0028] The bidirectional screw 201 is threadedly connected to the support frame 202, and the lower end of the support frame 202 is slidably connected within the groove 2 on the upper surface of the mounting base 1. Simultaneously, its lower end is also slidably connected to the positioning groove 204. When the bidirectional screw 201 rotates, the two support frames 202 slide horizontally towards or away from each other along the groove 2, achieving an opening and closing action. This allows for adaptation to pipes of different lengths, improving the versatility of the device and reducing the need to replace different equipment due to different pipe diameters. Furthermore, the V-shaped groove on the upper end of the support frame 202 is used to place the pipe, better conforming to the contour of a circular pipe, preventing the pipe from shaking or rolling. The device is flexible and does not require special design or frequent adjustments for pipes of different diameters, improving compatibility with various pipe diameters and greatly enhancing its versatility and applicability. Finally, the first lead screw 207 is rotated. Because the first lead screw 207 is threadedly connected to the mounting bracket 203, and the lower pressure ring 206 is rotatably connected to the lower end of the first lead screw 207 and fixedly connected to the telescopic end of the telescopic sleeve 205, as the first lead screw 207 rotates, the lower pressure ring 206 will move up and down along the axial direction of the telescopic sleeve 205 under the guidance of the telescopic sleeve 205, pressing and clamping the pipe to ensure the accuracy and stability of the repair operation.

[0029] In a preferred embodiment, the threaded assembly includes a second lead screw 301 rotatably connected inside the slide rail bracket 3, the lower end of the L-shaped bracket 302 is slidably connected to the inner wall of the slide rail bracket 3, the second lead screw 301 is threadedly connected to the L-shaped bracket 302, the gear assembly includes a mounting block 303 fixed to the lower end of the L-shaped bracket 302, a fixing ring 4 is fixed to the inner wall of the mounting block 303, a connecting ring 401 is rotatably connected to the inner wall of the fixing ring 4, a transmission gear 403 is rotatably connected to the mounting block 303 in the horizontal direction, tooth blocks 402 that mesh with the transmission gear 403 are evenly fixed to the outer wall of the connecting ring 401, six sets of cameras 6 are provided on the inner wall of the connecting ring 401, an electric push rod 5 is fixed to the side wall of the connecting ring 401, and a welding gun 501 is fixed to the telescopic end of the electric push rod 5.

[0030] By rotating the second lead screw 301, which is threadedly connected to the L-shaped bracket 302 and whose lower end is slidably connected to the inner wall of the slide rail bracket 3, the L-shaped bracket 302 moves along the inner track of the slide rail bracket 3, ensuring that the connecting ring 401, camera 6, and welding gun 501 are adjusted along the outer wall of the pipe. Rotating the transmission gear 403, which meshes with the uniformly fixed toothed blocks 402 on the outer wall of the connecting ring 401 and whose rotational connection is within the inner wall of the fixed ring 4, causes the connecting ring 401 to rotate circumferentially within the fixed ring 4. The six sets of cameras 6 on the inner wall of the connecting ring 401 rotate accordingly, enabling 360-degree all-around image acquisition of the pipe. This allows for faster and more comprehensive detection of various defects on the pipe surface, improving detection efficiency and accuracy. When the camera 6 detects a defect in the pipe, it activates the electric push rod 5. The telescopic end of the device pushes the welding gun 501 towards the pipe defect. By controlling the telescopic amount of the electric push rod 5, the welding gun 501 can accurately reach the repair position for welding repair. The detection camera 6 and the repair welding gun 501 are integrated into the same device. The functions are coordinated through the connecting ring 401, gear assembly and electric push rod 5. After the defect is detected, it can be repaired immediately without replacing equipment or readjusting the position, which greatly shortens the pipe repair time, improves work efficiency, simplifies the operation process and reduces manual operation costs. The camera 6 uses the optical imaging principle to clearly capture the image of the outer wall of the pipe and transmit it to the image acquisition and processing system. The image is analyzed using image recognition technology to find defects and perform intelligent detection. This is existing technology and will not be elaborated on further. The transmission gear 403 and the second lead screw 301 mentioned above are both driven by a motor, with the motor model being Y2-200L1-2Y.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, when the bidirectional screw 201 rotates, the two support frames 202 slide towards or away from each other in the horizontal direction along the slide groove 2 to achieve opening and closing action, which can adapt to pipes of different lengths. Then, the V-shaped groove opened at the upper end of the support frame 202 is used to place the pipe, which can better fit the outline of the circular pipe, and the pipe is not easy to shake or roll. Finally, the first screw 207 is rotated. Because the first screw 207 is threadedly connected to the mounting bracket 203, and the lower pressure ring 206 is rotatably connected to the lower end of the first screw 207 and fixedly connected to the telescopic end of the telescopic sleeve 205, as the first screw 207 rotates, the lower pressure ring 206 will move up and down along the axial direction of the telescopic sleeve 205 under the guidance of the telescopic sleeve 205, and press down and clamp the pipe.

[0033] During inspection and repair, as the second lead screw 301 rotates, the L-shaped bracket 302 moves along the internal track of the slide rail bracket 3, ensuring that the connecting ring 401, camera 6, and welding gun 501 are adjusted along the outer wall of the pipe. The transmission gear 403 rotates, and because the transmission gear 403 meshes with the toothed blocks 402 that are evenly fixed on the outer wall of the connecting ring 401, and the connecting ring 401 is rotatably connected to the inner wall of the fixed ring 4, the rotation of the transmission gear 403 will drive the connecting ring 401 to rotate circumferentially within the fixed ring 4. The six sets of cameras 6 on the inner wall of the connecting ring 401 rotate accordingly, enabling 360-degree all-round image acquisition of the pipe, which can more quickly and comprehensively detect various defects on the pipe surface, improving the efficiency and accuracy of inspection. When the camera 6 detects a defect in the pipe, the electric push rod 5 is activated. The telescopic end of the electric push rod 5 pushes the welding gun 501 to move towards the defect in the pipe. According to the position and size of the defect, by controlling the telescopic amount of the electric push rod 5, the welding gun 501 can accurately reach the repair position and perform welding repair work.
