Description

Technical Field

[0001] The present invention relates to the technical field of sensors, and in particular to a sensor based on a pipe network monitoring system. Background Art

[0002] The pipeline leakage monitoring system, also known as pipeline leakage information management, monitors the liquid (crude oil or other liquid) transportation pipeline. Once a perforation or leakage occurs in the pipeline, the monitoring system can promptly issue an early warning to the staff through its information management system and promptly handle the location of the pipeline leakage. In the use of the pipeline network monitoring system, many sensors are often used to detect the outer wall of the pipeline under the action of the sensors.

[0003] When traditional monitoring sensors are used to detect the outer wall of a pipeline, the sensor is often installed at a fixed position on the pipeline to monitor the operation of the pipeline. However, since the length of the pipeline is often relatively long, a sensor fixed at a certain position cannot detect all pipelines. If cracks or leaks appear in the pipeline where the sensor is not installed, the staff cannot discover them in time and can only manually scan the pipeline regularly, resulting in certain deficiencies in the monitoring of the pipeline.

Since the outer wall of the No. 2 driving gear 605 and the outer wall of the No. 1 driven gear 603 are meshed with each other, the No. 1 driven gear 603 is driven to rotate under the action of the No. 2 driving gear 605, thereby realizing the rotation of the driving roller 602, and then the mobile frame 2 can move on the outer wall of the pipeline 1. During the movement, the outer wall of the pipeline 1 can be better and more comprehensively monitored.

Since the outer wall of the third driving gear 703 and the outer wall of the second driven gear 705 are meshed with each other, the rotation of the second driven gear 705 is driven, thereby driving the generator 704 to generate electricity during the rotation of the second driven gear 705.

[0044] In a preferred embodiment, the outer wall of the support wheel 10 fits the outer wall of the pipe 1 , and the support wheel 10 is made of natural rubber. The inner wall diameter of the cleaning component 3 is equal to the outer wall diameter of the pipe 1 .

[0045] In the above structure, by opening the support groove 9 on the inner wall of the mobile frame 2 and the support wheel 10 provided on the inner wall of the support groove 9, the outer wall of the support wheel 10 is fitted with the outer wall of the pipeline 1, so that the support wheel 10 can play an overall supporting role for the pipeline 1, and then the mobile frame 2 can move more smoothly on the outer wall of the pipeline 1, thereby realizing the monitoring and detection of the outer wall of the pipeline 1.

[0046] In a preferred embodiment: the outer wall of the linkage shaft 505 passes through the outer wall of the sliding frame 503, and the outer wall of the No. 1 driving gear 506 is respectively meshed with the outer walls of the No. 1 arc rail 501 and the No. 2 arc rail 502, and the inner wall shape of the sliding frame 503 matches the outer wall shape of the No. 1 arc rail 501 and the No. 2 arc rail 502.

Since the outer wall of the No. 1 driving gear 506 is meshed with the outer walls of the No. 1 arc rail 501 and the No. 2 arc rail 502, the sliding frame 503 can be driven to move on the outer walls of the No. 1 arc rail 501 and the No. 2 arc rail 502 under the action of the dual-axis motor 504.

[0048] In a preferred embodiment: the outer wall of the ultrasonic sensor 508 is in contact with the outer wall of the pipe 1, the two ends of the outer wall of the first arc rail 501 and the second arc rail 502 are respectively connected to the outer walls of the two sides of the mounting groove 4, and the dual-axis motor 504 is electrically connected to the battery pack 8.

[0049] In the above structure, by setting the No. 1 curved rail 501 and the No. 2 curved rail 502 on the inner walls of both sides of the installation groove 4, and setting the sliding frame 503 on the outer walls of the No. 1 curved rail 501 and the No. 2 curved rail 502, the sliding frame 503 can be moved along the outer walls of the No. 1 curved rail 501 and the No. 2 curved rail 502. During the movement of the sliding frame 503, the image sensor 507 can scan the outer wall of the pipeline 1, so that the image of the outer wall of the pipeline 1 is obtained under the action of the sliding frame 503 to distinguish the outer wall of the pipeline 1.

[0050] In a preferred embodiment: the outer wall of the second driving gear 605 is meshed with the outer wall of the first driven gear 603, and the outer wall diameter of the second driving gear 605 is smaller than the outer wall diameter of the first driven gear 603, the driving roller 602 is made of natural rubber, and the driving motor 604 is a low-speed high-torque motor.

[0051] In the above structure, by means of the mounting plate 601 arranged on the outer wall of the mobile frame 2 and the driving roller 602 arranged on the inner wall of the mounting plate 601, the No. 2 driving gear 605 is driven by the driving motor 604 to rotate. Since the outer wall of the No. 2 driving gear 605 is meshed with the outer wall of the No. 1 driven gear 603, the driving roller 602 rotates with the rotation of the No. 1 driven gear 603. Under the action of the rotation of the driving roller 602, the mobile frame 2 can move as a whole on the outer wall of the pipe 1.

[0052] In a preferred embodiment: the outer wall of the second driven gear 705 meshes with the outer wall of the third driving gear 703, and the outer wall diameter of the second driven gear 705 is smaller than the outer wall diameter of the third driving gear 703, and the generator 704 is electrically connected to the battery pack 8.

[0053] In the above structure, by setting the No. 3 driving gear 703 on the outer wall of the driven roller 702, and the generator 704 and the No. 2 driven gear 705 on the outer wall of the mounting frame 701, the driven roller 702 can be rotated during the movement of the mobile frame 2, and the No. 3 driving gear 703 can be driven to rotate during the rotation of the driven roller 702, thereby driving the No. 2 driven gear 705, and then the generator 704 can generate electrical energy when the No. 2 driven gear 705 rotates, and the electrical energy is stored in the battery pack 8.

[0054] Working principle: during the use of the above-mentioned device, when it is necessary to inspect the outer wall of the pipeline 1, the mobile frame 2 and the cleaning component 3 are integrally installed on the outer wall of the pipeline 1, and the driving motor 604 is started to drive the second driving gear 605 to rotate under the action of the driving motor 604. During the rotation of the second driving gear 605, the first driven gear 603 can be rotated, thereby driving the driving roller 602. During the rotation of the driving roller 602, the outer wall of the driving roller 602 and the outer wall of the pipeline 1 are fitted together, so that the driving frame 2 can be driven under the action of the rotation of the driving roller 602, so that the mobile frame 2 and the cleaning component 3 move along the outer wall of the pipeline 1. During the movement of the cleaning component 3, the inner wall of the scraper 303 and the outer wall of the pipe 1 are in contact with each other, and then the outer wall of the pipe 1 is scraped off under the action of the scraper 303 to clean the debris attached to the outer wall of the pipe 1. After the moving frame 2 moves forward for a certain distance, the driving motor 604 is turned off, and then the double-axis motor 504 is started. Under the drive of the double-axis motor 504, the first driving gear 506 rotates, and the outer wall of the first driving gear 506 is meshed with the outer wall of the first arc rail 501 and the outer wall of the second arc rail 502. Then, under the drive of the double-axis motor 504, the sliding frame 503 can move on the outer wall of the first arc rail 501 and the second arc rail 502. As the sliding frame 50 3, the image sensor 507 can collect images of the outer wall of the pipeline 1, and take images on the outer wall of the pipeline 1 to determine whether there is leakage on the outer wall of the pipeline 1. During the movement of the sliding frame 503, the ultrasonic sensor 508 can emit ultrasonic waves to the outer wall of the pipeline 1. Under the action of the ultrasonic sensor 508, the corrosion and cracks inside the pipeline 1 are monitored, and the four sliding frames 503 respectively set on the outer wall of the moving frame 2 are used to monitor a large area around the pipeline 1. After the outer wall of a section of the pipeline 1 is monitored, the driving motor 604 is started again, and the driving roller 602 is driven again, so that the moving frame 2 moves on the outer wall of the pipeline 1 again, and the moving frame 2 moves on the outer wall of the pipeline 1 again. When the mobile frame 2 moves to an unmonitored portion, the sliding frame 503 is used again to scan and monitor the outer wall of the pipeline 1 to ensure the normal use of the pipeline 1. During the movement of the mobile frame 2, the driven roller 702 moves with the movement of the mobile frame 2, thereby driving the No. 2 driven gear 705. Since the outer wall diameter of the No. 3 driving gear 703 is larger, the No. 2 driven gear 705 can be driven better, so that the generator 704 can generate electrical energy and store the electrical energy in the battery pack 8. The dual-axis motor 504 is powered by the battery pack 8, and the sliding frame 503 is driven better by the dual-axis motor 504, so that it can better scan and monitor the outer wall of the pipeline 1.
