Abstract
Description
Technical Field
[0001] This utility model relates to the field of special equipment inspection and maintenance technology, specifically a positioning and protection mechanism for petrochemical plant pipelines. Background Technology
[0002] During the periodic inspection and maintenance of specialized equipment such as petrochemical plants, the intricate complexity and similarity of pipelines pose significant challenges to locating target pipelines, leading to low work efficiency. Currently, the commonly used method is to mark the pipelines with markers, but this method has many serious problems.
[0003] Petrochemical plants operate in complex environments with a vast number of pipelines; a single large petrochemical production line can have thousands or even tens of thousands of pipelines. For example, in the actual maintenance work of a large petrochemical enterprise, markings frequently become ineffective due to their susceptibility to erasure or removal, and the often unclear nature of many markings. Statistics show that approximately 30% of the markings become unreadable after a period of use. Therefore, we need to implement protective mechanisms for these markings. To address this issue, we propose a positioning and protection mechanism for petrochemical plant pipelines. Summary of the Invention
[0004] The main purpose of this invention is to overcome the problem that the commonly used method in the prior art is to mark pipelines with markers. However, because the marks are easily smeared or removed, and many markings are unclear, the marks often fail. According to statistics, about 30% of the marks cannot be properly identified after a period of use. Therefore, we propose a positioning and protection mechanism for petrochemical plant pipelines.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and protection mechanism for a petrochemical plant pipeline, comprising a pipe gallery, a reinforcing rib fixedly connected to the side end of the pipe gallery, a petrochemical pipeline arranged inside the pipe gallery, a positioning plate fixedly connected to the top of the petrochemical pipeline, a pipeline flange fixedly connected inside the positioning plate, a rotating seat rotatably connected to the end of the pipeline flange away from the positioning plate, a placement chamber fixedly connected to the upper end of the rotating seat, a digital identification card adhered inside the placement chamber, a fixed box fixedly connected inside the placement chamber, a sliding block slidably connected inside the fixed box, a damping spring fixedly connected inside the fixed box, a connecting block fixedly connected to the end of the damping spring away from the fixed box, and the connecting block fixedly connected to the front of the sliding block.
[0006] As a further preferred embodiment of this technical solution, a movable block is fixedly connected below the sliding block, the movable block passes through the fixed box, the movable block is slidably connected to the fixed box, a displacement block is fixedly connected to the end of the sliding block away from the sliding block, a limiting roller is fixedly connected to the bottom of the fixed box, a first positioning rod is rotatably connected to the surface of the limiting roller, and a pulley is fixedly connected above the first positioning rod, the pulley being located inside the displacement block.
[0007] As a further preferred embodiment of this technical solution, the pulley is slidably connected to the displacement block, a linkage rod is fixedly connected inside the fixed box, the linkage rod is located above the damping spring, the linkage rod is engaged with the sliding block, a sliding rod is fixedly connected to the front of the sliding block, and the sliding rod passes through the fixed box.
[0008] As a further preferred embodiment of this technical solution, the surface of the placement compartment is provided with a rotating groove, a fixing block is fixedly connected to the inner wall of the rotating groove, a movable shaft is rotatably connected to the end of the fixing block away from the rotating groove, a protective cover plate is fixedly connected to the front of the movable shaft, and a second positioning rod is fixedly connected to the lower end of the protective cover plate, the second positioning rod being engaged with the first positioning rod.
[0009] As a further preferred embodiment of this technical solution, a monitoring box is fixedly connected to the top of the inner wall of the pipe gallery, and a pressure monitoring sensor is electrically connected inside the monitoring box. An integrated infrared camera is rotatably connected to the front of the pressure monitoring sensor.
[0010] As a further preferred embodiment of this technical solution, a computing gateway is fixedly connected to the top of the inner wall of the pipe gallery, and the number of monitoring boxes is set to two. The two monitoring boxes are symmetrically arranged about the center of the computing gateway, and the computing gateway is located above the petrochemical pipeline.
[0011] As a further preferred embodiment of this technical solution, a pad is fixedly connected to the bottom of the inner wall of the pipe gallery, a petrochemical pipe is snapped onto the upper end of the pad, and a notice board is fixedly connected to the surface of the petrochemical pipe. The number of notice boards is set to two, and the two notice boards are symmetrically arranged about the center of the petrochemical pipe.
[0012] This utility model provides a positioning and protection mechanism for petrochemical plant pipelines, which has the following advantages:
[0013] (1) By rotating the protective cover, the protective cover will drive the movable shaft to rotate, and the second positioning rod under the protective cover will move to the position of the first positioning rod. When the top of the protective cover contacts the sliding rod, the sliding rod will drive the movable block under the sliding block to slide inside the fixed box. As the sliding block slides, the connecting block set at the top of the sliding block will move to the damping spring. Since the lower end of the movable block is fixedly connected to the displacement block, the movable block will also drive the pulley inside the displacement block to slide together when it slides. The sliding of the pulley will drive the second positioning rod below to descend. When the first positioning rod contacts the descending second positioning rod, it will complete the locking, thereby protecting the data identification card, thus avoiding the problem that the marking is easily smeared or removed, and that many markings are unclear, resulting in the failure of the marking, thus avoiding unnecessary losses.
[0014] (2) This utility model uses a digital identification card attached inside the placement compartment. The digital identification card is made of corrosion-resistant and high-temperature resistant materials to ensure long-term use in the petrochemical environment. The digital identification card is bound to the unique identification information of the pipeline, including the pipeline code, location information and functional description. After scanning the digital card identification, the system displays the three-dimensional layout information of the pipeline through virtual reality technology. Users can view the three-dimensional layout of the pipeline through mobile devices or VR devices. The virtual reality technology is implemented using the Unity engine and supports multiple platforms (such as iOS, Android and Windows). At the same time, the user inputs the target pipeline code, and the system guides the user to find the target pipeline based on the three-dimensional layout information. The data storage of the three-dimensional layout information adopts a distributed database architecture (such as MongoDB or Cassandra) and is stored in the cloud or local database to ensure real-time updates and synchronization of data.

[0027] Example 1: Please refer to Figure 1 , 4 5
[0028] A positioning and protection mechanism for a petrochemical plant pipeline includes: a reinforcing rib 4 fixedly connected to the side of a pipe gallery 1; a petrochemical pipeline 3 housed inside the pipe gallery 1; a positioning plate 7 fixedly connected to the top of the petrochemical pipeline 3; a pipeline flange 9 fixedly connected inside the positioning plate 7; a rotating seat 10 rotatably connected to the end of the pipeline flange 9 away from the positioning plate 7; a placement chamber 8 fixedly connected to the upper end of the rotating seat 10; a digital identification card adhered inside the placement chamber 8; a fixed box 16 fixedly connected inside the placement chamber 8; a sliding block 18 slidably connected inside the fixed box 16; a damping spring 20 fixedly connected inside the fixed box 16; a connecting block 21 fixedly connected to the end of the damping spring 20 away from the fixed box 16; and the connecting block 21 fixedly connected to the front of the sliding block 18. The digital identification card generates a unique digital identifier for each pipeline, using a hash algorithm (such as SHA-256) to ensure the uniqueness and security of the identifier. The digital identifier can be a QR code or an RFID tag, which is bound to the unique identification information of the pipeline (such as pipeline code, location, function, etc.). The digital labels are made of corrosion-resistant and high-temperature-resistant materials (such as polytetrafluoroethylene) and undergo waterproof, dustproof, and UV-resistant treatment to ensure long-term use in petrochemical environments. Users can scan the digital labels using mobile devices (such as smartphones and tablets) or dedicated scanning equipment, and the system automatically loads the 3D layout information of the pipelines. Utilizing virtual reality technology (such as Unity or Unreal Engine), users can view the 3D layout of the pipelines through mobile devices or VR devices, achieving an immersive viewing experience. The system provides multiple interaction methods, such as zooming, rotating, and panning, allowing users to view the pipelines from different angles.
[0029] A movable block is fixedly connected to the lower part of the sliding block 18. The movable block passes through the fixed box 16 and is slidably connected to the fixed box 16. A displacement block 24 is fixedly connected to the end of the sliding block away from the sliding block 18. A limiting roller 25 is fixedly connected to the bottom of the fixed box 16. A first positioning rod 22 is rotatably connected to the surface of the limiting roller 25. A pulley 23 is fixedly connected above the first positioning rod 22. The pulley 23 is located inside the displacement block 24.
[0030] The pulley 23 is slidably connected to the displacement block 24. The fixed box 16 is fixedly connected to the inside of the fixed box 16. The linkage rod 19 is located above the damping spring 20. The linkage rod 19 is engaged with the sliding block 18. The front of the sliding block 18 is fixedly connected to the sliding rod 17, which passes through the fixed box 16.
[0031] Example 2: Please refer to Figure 3
[0032] The surface of the placement compartment 8 is provided with a rotating groove. A fixing block 11 is fixedly connected to the inner wall of the rotating groove. A movable shaft 12 is rotatably connected to the end of the fixing block 11 away from the rotating groove. A protective cover plate 13 is fixedly connected to the front of the movable shaft 12. A second positioning rod is fixedly connected to the lower end of the protective cover plate 13. The second positioning rod is engaged with the first positioning rod 22. This configuration, by rotating the protective cover 13, will move the second positioning rod towards the position of the first positioning rod 22. When the top of the protective cover 13 contacts the sliding rod 17, the sliding rod 17 will drive the movable block below the sliding block 18 to slide inside the fixed box 16, thereby causing the connecting block 21 at the top of the sliding block 18 to move towards the damping spring 20. When the movable block slides, it will also drive the pulley 23 inside the displacement block 24 to slide together. The sliding of the pulley 23 will drive the second positioning rod below to descend. When the first positioning rod 22 contacts the descending second positioning rod, it will complete the engagement, thereby protecting the data identification card and preventing the markings from being easily erased or removed, and preventing the markings from becoming invalid due to unclear markings, thus avoiding unnecessary losses.
[0033] Example 3: Please refer to Figure 6
[0034] A monitoring box is fixedly connected to the top of the inner wall of the pipe gallery 1. A pressure monitoring sensor 14 is electrically connected inside the monitoring box, and an integrated infrared camera 15 is rotatably connected to the front of the pressure monitoring sensor 14. This setup, in conjunction with the pressure monitoring sensor 14, allows for real-time monitoring of the pipeline pressure, preventing overpressure or leakage, and uploading the data to the configured computing gateway 2. The computing gateway 2 can locally process the data transmitted from the pressure monitoring sensor 14 and then upload it to the system, reducing the load on the cloud.
[0035] The inner wall of pipe gallery 1 is fixedly connected to a computing gateway 2. Two monitoring boxes are symmetrically positioned about the center of the computing gateway 2, which is located above the petrochemical pipeline 3. The computing gateway 2 records data such as the pipeline's 3D layout and functional descriptions, storing this data in a distributed database (e.g., MongoDB or Cassandra), which can be stored in the cloud or locally. A real-time synchronization mechanism ensures real-time data updates and synchronization. When pipeline information changes, the system automatically updates the database to guarantee accuracy and consistency. The user inputs the target pipeline code, and the system automatically generates a navigation path based on the 3D layout information using a path planning algorithm (e.g., A-Star algorithm). The navigation path is displayed visually on the user's device, guiding them to quickly locate the target pipeline. The system also provides voice navigation for convenient use when operating the equipment is inconvenient. The system also supports offline mode, allowing users to search for pipeline information in a local database without a network connection. Local database updates are performed periodically or manually to ensure the timeliness and accuracy of offline data. In offline mode, the system still provides basic pipeline location and navigation functions, ensuring efficient operation even in complex environments. The system also supports multi-user collaboration, allowing multiple maintenance personnel to view and operate the same pipeline system simultaneously. A permission management mechanism ensures different users have appropriate operational and data access rights, improving team collaboration efficiency.
[0036] Example 4: Please refer to Figure 2
[0037] The inner wall of the pipe gallery 1 is fixedly connected to a pad 5 at its bottom. The upper end of the pad 5 is clamped to a petrochemical pipe 3. A notice board 6 is fixedly connected to the surface of the petrochemical pipe 3. Two notice boards 6 are arranged symmetrically about the center of the petrochemical pipe 3. The notice boards 6 allow users to see the specific information of the pipeline more intuitively, making it easier for users to understand the situation.
[0038] This utility model provides a positioning and protection mechanism for pipelines in a petrochemical plant. The specific working principle is as follows: During use, the user places the digital identification card of the pipeline to be recorded inside the placement compartment 8. Then, the protective cover 13 is rotated, causing the movable shaft 12 to rotate. The second positioning rod below the protective cover 13 moves towards the position of the first positioning rod 22. When the top of the protective cover 13 contacts the sliding rod 17, the sliding rod 17 causes the movable block below the sliding block 18 to slide inside the fixed box 16. Due to the sliding of the sliding block 18, the connecting block 21 at the top of the sliding block 18 moves towards the damping spring 20. Furthermore, because the lower end of the movable block is fixedly connected to… The displacement block 24, when sliding, will also drive the pulley 23 inside the displacement block 24 to slide together. The sliding of the pulley 23 will drive the second positioning rod below to descend. When the first positioning rod 22 contacts the descending second positioning rod, it will complete the engagement, thereby effectively protecting the digital identification card. At the same time, since an integrated infrared camera 15 is installed above the petrochemical pipeline 3, it can work with the pressure monitoring sensor 14 to monitor the pressure in the pipeline in real time, prevent overpressure or leakage, and upload the data to the set computing gateway 2. The computing gateway 2 can process the data transmitted from the pressure monitoring sensor 14 locally, and then upload it to the system, reducing the cloud load.
