Description

[0001] The present invention relates to the technical field of oil and gas pipeline operation and maintenance equipment, and specifically to a big data-based oil and gas pipeline network safety operation and maintenance system. Background Art

[0002] At present, oil and gas pipelines are the main means for transporting natural gas, crude oil and refined oil. During long-distance transportation, due to the long-term operation of oil and gas pipelines, problems such as pipeline leakage, deformation and damage to the pipeline cover may occur, which will lead to impacts on the environment and waste of energy during the transmission process. Therefore, it is necessary to conduct timely inspections on oil and gas pipelines and then carry out repairs and maintenance.

[0003] When oil and gas pipelines need to be inspected and maintained, brackets are needed to effectively support them, so that when the valves at both ends are closed, the oil and gas pipelines in this section can be inspected separately. Inspection and maintenance basically also include sealing, welding, etc., and some leaks are dealt with. However, the current brackets only have support. Some positions that need to be dealt with are at the bottom, which makes it impossible for staff to operate and inspect in a normal state. At the same time, at some inspection locations, since the oil and gas pipelines are set up in the field for a long time, a lot of impurities will accumulate on the surface, which will require staff to perform additional treatment later, reducing the efficiency of inspection and increasing labor.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1-6As shown, the present invention provides a big data-based oil and gas pipeline network safety operation and maintenance system, including a data collection system, a data preprocessing module, a data analysis and modeling module, visualization and reporting, regional personnel scheduling, and equipment maintenance. The data collection system can specifically use sensor data, surveillance video, meteorological data, historical maintenance records, etc. These data can be collected in real time through Internet of Things (IoT) devices and sensors;

[0031] The data preprocessing module cleans and preprocesses the data collected in the data collection system, removing noise and outliers, filling in missing data, and standardizing the data format. This step is important for ensuring data quality and facilitates subsequent data analysis and model building.

[0032] The data analysis and modeling module applies data analysis techniques and machine learning algorithms to conduct in-depth analysis of data. Common analysis methods include anomaly detection, trend prediction, and fault diagnosis. By establishing prediction models and risk assessment models, potential safety hazards can be identified and possible failures can be predicted.

[0033] Visualization and reporting: After analyzing the data, the analysis results are displayed in a visual way, such as through dashboards and charts. This helps operation and maintenance personnel quickly understand the operation status and safety status of the pipeline network and generate detailed reports for decision-making reference.

[0034] Regional personnel dispatch is the operation and maintenance system backend that dispatches and allocates local staff according to the goals determined after inspection. Maintenance personnel will be able to repair oil and gas pipelines according to the inspection equipment.

[0035] The maintenance equipment includes a maintenance bracket, which specifically includes a bottom plate 1. A base 11 is provided directly above the bottom plate 1. A first placement slot 14 is provided through the middle end of the top of the base 11. The first placement slot 14 can be aligned with the bottom of the oil and gas pipe that needs to be repaired. The top of the base 11 is located on both sides of the first placement slot 14 and is equipped with a mobile frame 2. The mobile frame 2 is L-shaped as a whole, and a cleaning component is provided on the top of the mobile frame 2; vertically arranged auxiliary plates 4 are installed on both sides of the base 11, and a second placement slot 46 corresponding to the first placement slot 14 is provided on the top of the auxiliary plate 4. The inner side of the second placement slot 46 is provided with an installation slot 41, and an arc-shaped driving roller 42 is provided in the installation slot 41. The top of the auxiliary plate 4 is located at both ends of the second placement slot 46 and is slidably provided with an arc-shaped positioning plate 5.

[0036] The cleaning component includes a cleaning plate 21, which is circular and arranged at the top of the movable frame 2 and close to the side of the first placement slot 14. The top of the movable frame 2 is inclined. A driving motor 22 is fixedly installed on the side of the top of the movable frame 2 away from the cleaning plate 21. The output end of the driving motor 22 is coaxially fixed at the center of the cleaning plate 21. The side of the movable frame 2 close to the base 11 is arranged parallel to the top of the base 11 and is provided with a movable groove 23. A push rod 24 is movably inserted in the movable groove 23. A horizontally arranged rotating plate 25 is fixed on the top of the push rod 24, and a vertically arranged rotating shaft 26 is fixed on the end of the rotating plate 25 away from the push rod 24.

[0037] By adopting the above technical solution, the rotating shaft 26, the rotating plate 25 and the push rod 24 will drive the movable frame 2 to translate back and forth repeatedly, so that the oil and gas pipe can be fully and effectively cleaned at the position required for the above-mentioned maintenance, thereby improving the cleanliness of its surface and meeting the subsequent welding or repairing of the position to improve the quality of the treatment.

[0038] An inverted U-shaped fixing frame 28 is fixed to the top of the base 11 near the rotating plate 25. The top of the rotating shaft 26 rotates and passes through the fixing frame 28. A first motor 27 is fixedly placed on the upper surface of the fixing frame 28. The output end of the first motor 27 is coaxially fixed on the rotating shaft 26. Support rods 29 are fixed on both sides of the movable frame 2, and the support rods 29 can pass through the fixing frame 28.

[0039] By adopting the above technical solution, the first motor 27 can provide power for the rotation of the rotating shaft 26 , and the support rod 29 can ensure that the movable frame 2 can move stably above the base 11 .

[0040] Two symmetrically distributed grooves 3 are provided through the bottom of the base 11, and a driving gear 31 is rotatably provided at the middle end of the groove 3. Two diagonally distributed tooth plates 32 are engaged with the driving gear 31. A connecting plate 33 is fixed on the side of the two tooth plates 32 away from the driving gear 31. The ends of the two connecting plates 33 away from the groove 3 are respectively fixedly connected to the two auxiliary plates 4. An electric push rod 34 is fixedly installed on the bottom of the base 11, and the output end of the electric push rod 34 is coaxially fixed on one of the auxiliary plates 4.

[0041] By adopting the above technical solution, when the output section of the electric push rod 34 is recovered, one of the auxiliary plates 4 will be controlled to move toward the base 11. At this time, the two diagonally distributed tooth plates 32 connected by a driving gear 31 in the groove 3 will move toward each other at the same time, thereby controlling the other auxiliary plate 4 to move toward the base 11, and controlling the two auxiliary plates 4 to be close to each other, so that the overall footprint of the maintenance bracket is reduced, which is convenient for subsequent carrying or adjustment of the distance between the two auxiliary plates 4, and better support for the oil and gas pipelines.

[0042] The ends of the driving rollers 42 are fixed with driving shafts 43, and the ends of the driving shafts 43 away from the driving rollers 42 rotate and pass through the auxiliary plate 4. Multiple driving shafts 43 pass through one end of the auxiliary plate 4 and are connected by a first belt 44. Specifically, a transmission wheel with a gear is fixed on the driving shaft 43 passing through one end of the auxiliary plate 4. The first belt 44 can be a toothed belt, which is jointly connected with the transmission wheel at the end of the driving shaft 43, so that multiple driving rollers 42 can be driven to rotate in the same direction at one time.

[0043] By adopting the above technical solution, the first belt 44 can drive the multiple driving rollers 42 to rotate synchronously, so that the oil and gas pipes placed on the second placement groove 46 can rotate and adjust their own positions.

[0044] A second motor 45 is fixedly mounted on the bottom of the auxiliary plate 4 near one of the driving rollers 42 , and an output end of the second motor 45 is coaxially fixedly disposed on the driving roller 42 .

[0045] By adopting the above technical solution, the second motor 45 can drive the driving roller 42 to rotate, providing power for its operation, and facilitating operation by the staff.

[0046] The top of the auxiliary plate 4 is located below the positioning plate 5 and is provided with a slide groove 51 . A screw rod 52 is rotatably provided in the slide groove 51 . A slider 53 is threadedly inserted into the screw rod 52 . The top of the slider 53 is fixedly provided on the positioning plate 5 .

[0047] By adopting the above technical solution, the provided screw rod 52 can drive the slider 53 to move the positioning plate 5 toward the oil and gas pipe, thereby positioning it and avoiding severe vibration of the oil and gas pipe, which affects subsequent processing and causes a decrease in accuracy.

[0048] A rotating rod 54 is fixedly provided on the side of the screw rod 52 away from the second placement groove 46, and a transmission rod 56 is movably inserted into the bottom of the placement groove. The two ends of the transmission rod 56 are connected to the adjacent rotating rods 54 through a second belt 57. A rotating wheel 55 is fixedly provided at the end of one of the rotating rods 54 located on the auxiliary plate 4.

[0049] By adopting the above technical solution, the transmission rod 56 and the second belt 57 can simultaneously drive the two screw rods 52 to rotate synchronously, thereby improving the convenience of operation.

[0050] Two symmetrically distributed cylinders 12 are installed on the upper surface of the bottom plate 1. The output ends of the cylinders 12 are coaxially fixed to the bottom of the base 11. Telescopic rods 13 are installed at the four corners of the bottom of the base 11 and the four corners of the bottom plate 1.

[0051] By adopting the above technical solution, the provided cylinder 12 can control the base 11 to move up and down, and when work is required, the base 11 is controlled to move up and against the oil and gas pipes for support.

[0052] Working principle: When the staff is inspecting and repairing the oil and gas pipe, the maintenance bracket is placed as a whole at the bottom of the oil and gas pipe. The cylinder 12 will push the base 11 above, so that the first placement groove 14 and the second placement groove 46 will be against the bottom of the oil and gas pipe. The valves at both ends of the oil and gas pipe to be inspected and maintained can be closed first, and the flanges at both ends of the oil and gas pipe can be disassembled after the oil and gas pipe is separated, so that the oil and gas pipe section can be separated;

[0053] When the second motor 45 starts working, it can directly drive one of the driving rollers 42 to rotate. At this time, since the driving shafts 43 are fixed at the ends of the multiple driving rollers 42, and the multiple driving shafts 43 are connected by the first belt 44, the first belt 44 will drive the multiple driving shafts 43 to rotate together, so that the driving shaft 43 causes the multiple driving rollers 42 in the installation groove 41 to rotate synchronously in the same direction. At this time, the oil and gas pipes placed on the auxiliary plate 4 will be driven by the multiple driving rollers 42 to rotate, so that when the staff handles the oil and gas pipes that need maintenance and overhaul, the position of the oil and gas pipes to be handled can be conveniently rotated to the top or side, thereby increasing the convenience of the staff in subsequent processing of the oil and gas pipes;

[0054] When the above device drives the oil and gas pipe to rotate, a mobile frame 2 is installed at both ends of the top of the base 11 located between the two auxiliary plates 4. The cleaning plate 21 set on the top of the mobile frame 2 is driven by the driving motor 22 to rotate rapidly. At the same time, the first motor 27 will directly drive the rotating shaft 26 to rotate, and the rotating plate 25 fixed at the bottom of the rotating shaft 26 will rotate. The rotating rotating plate 25 will drive the push rod 24 fixed at the end to push the mobile frame 2 to move. As the rotating plate 25 is continuously driven by the rotating shaft 26, the push rod 24 at the end of the rotating plate 25 will continuously rotate. The movable frame 2 moves from one end to the other in the movable groove 23 provided on the movable frame 2. At this time, the movable frame 2 is driven to continuously move back and forth on the top of the base 11, so that the entire movable frame 2 will drive the rotating cleaning rough plate 21 to repeatedly translate. When the oil and gas pipe is driven to rotate by the auxiliary plate 4, the cleaning rough plate 21 is driven to repeatedly translate. Through the above operation, the oil and gas pipe can be fully and effectively cleaned at the position required for maintenance, thereby improving the cleanliness of its surface and meeting the requirements of subsequent welding or sewing at the position, thereby improving the quality of treatment.

[0055] After the surface treatment of the oil and gas pipes by the above operations, the staff can drive the rotating wheel 55 to rotate. At this time, the rotating wheel 55 will drive the rotating rod 54 to drive the screw rod 52 to rotate. The rotating rods 54 at both ends of the auxiliary plate 4 are rotated through the transmission rod 56 and the second belt 57. At this time, the screw rods 52 at both ends of the auxiliary plate 4 will rotate in the same direction at the same time. The thread directions of the two opposite screw rods 52 are opposite, so that when rotating in the same direction, the sliders 53 on the two screw rods 52 will be driven to move toward or away from each other at the same time. The sliders 53 moving toward each other will drive the positioning plate 5 to position the oil and gas pipes on the auxiliary plate 4. The positioning plates 5 on the two auxiliary plates 4 fix the ends of the oil and gas pipes at the same time, increasing the support of the maintenance bracket for the oil and gas pipes, thereby ensuring that the oil and gas pipes are prevented from vibrating violently during subsequent processing, affecting subsequent processing and resulting in a decrease in accuracy.

[0056] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
