Technical Field
[0001] The present application relates to the technical field of oil pipelines, and in particular to a detection device for internal flaw detection of oil pipelines. Background Art
[0002] Oil pipelines are one of the main equipment in the oil storage and transportation industry. At present, during long-term use, oil pipelines may suffer from internal damage such as cracks and breakages due to corrosion and wear. If these damages are not discovered and handled in time, they may cause leakage accidents, environmental pollution, and even safety accidents. Therefore, it is very necessary to conduct regular internal flaw detection on oil pipelines.
[0003] Existing internal flaw detection devices and methods for oil pipelines have problems such as complex operation and low efficiency. Some more advanced detection devices are expensive and difficult to meet actual detection needs. Utility Model Content

It solves the problems of complex operation and low efficiency in existing internal flaw detection devices and methods for oil pipelines, as well as the problem that some more advanced detection devices are expensive and difficult to meet actual detection needs.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a detection device for internal flaw detection of oil pipelines, comprising a shell, a base is fixedly connected to the back side of the shell, an equidistantly arranged searchlight is fixedly connected to the outer circumferential surface of the base, a camera is fixedly connected to the back side of the base, a motor is fixedly connected to the inner wall of the shell, an output shaft is rotatably connected to the inside of the motor, two threaded tubes are threadedly connected to the outer circumferential surface of the output shaft, an equidistantly arranged rotating rod is rotatably inserted into the inside of the shell, each rotating rod is fixedly connected to a fixing frame, a fixed seat is fixedly connected to the side of the fixing frame away from the rotating rod, a sliding rod is slidably inserted into the inside of the fixed seat, and a roller is fixedly connected to the side of the sliding rod away from the fixed seat.
[0006] Through the above scheme, since the existing internal flaw detection devices and methods of oil pipelines have problems such as complex operation and low efficiency, and some more advanced detection devices are expensive and difficult to meet actual detection needs, the rack drives the rotating rod to rotate under the action of the gear during the movement, prompting the fixed frame to drive the roller to retract and extend, so that the roller can be closely attached to the inner wall of the oil pipeline, support the detection device, and drive the detection device to perform mobile detection, thereby improving the detection efficiency, facilitating operation, and reducing costs.
[0007] Furthermore, the outer circumferential surface of each threaded tube is fixedly connected to a limiting ring, the interior of the shell is fixedly connected to a limiting rod, and the inner wall of the limiting ring is slidably connected to the outer circumferential surface of the limiting rod.
[0008] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating with the output shaft, so that the threaded tube is always moved laterally.
[0009] Furthermore, the invention is characterized in that a fixing ring is fixedly connected to the interior of the housing, and the outer circumferential surface of the output shaft is rotatably plugged into the interior of the fixing ring.
[0010] Through the above solution, the output shaft is supported and reinforced to increase the stability of the output shaft movement.
[0011] Furthermore, two limit plates are fixedly connected to the outer circumferential surface of the sliding rod, and the outer surface of each limit plate is slidably connected to the inside of the fixing seat.
[0012] Through the above solution, the sliding rod is restricted to prevent the sliding rod from rotating, thereby increasing the stability of the sliding rod movement.
[0013] Furthermore, a damper is fixedly connected inside the fixing seat, and the other end of the damper is fixedly connected to the bottom surface of the sliding rod.
[0014] Through the above solution, the roller is buffered and shock-absorbed by the damper, thereby increasing the stability of the detection device during movement.
[0015] Furthermore, a spring is fixedly connected inside the fixing seat, and the other end of the spring is fixedly connected to the bottom surface of the sliding rod.
[0016] Through the above scheme, the spring enables the roller to be in close contact with the inner wall of the oil pipeline to support the detection device, and cooperates with the damper to buffer and reduce shock of the detection device.
[0017] Furthermore, the outer circumferential surface of the threaded tube is fixedly connected with racks arranged at equal distances, and the outer circumferential surface of the rotating rod is fixedly sleeved with a gear, and the gear is meshed with the rack.
[0018] Through the above scheme, the rack can drive the rotating rod to rotate through the gear during the movement, thereby driving the roller to be retracted and extended.
[0019] Furthermore, the outer circumferential surface of the output shaft is provided with two sections of thread structures, and the thread track directions of the two sections of thread structures on the outer circumferential surface of the output shaft are opposite.
[0020] Through the above scheme, the threaded tube can be moved in relative directions, and then the rollers at both ends are driven to open and close in relative directions under the action of the rack and the gear.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] The detection device for internal flaw detection of oil pipelines drives the rotating rod to rotate under the action of the gear during the movement of the rack, prompting the fixed frame to drive the roller to retract and extend, so that the roller can be closely attached to the inner wall of the oil pipeline, thereby achieving the effect of being able to support the detection device and drive the detection device to perform mobile detection, improving the detection efficiency, facilitating operation, and reducing costs, and solving the problems of complex operation and low efficiency in existing internal flaw detection devices and methods for oil pipelines, and also solving the problem that some more advanced detection devices are expensive and difficult to meet actual detection needs.

[0031] See also Figure 3 The outer circumference of each threaded tube 7 is fixedly connected to a limit ring 9, and the interior of the housing 1 is fixedly connected to a limit rod 10. The inner wall of the limit ring 9 is slidably connected to the outer circumference of the limit rod 10 to limit the threaded tube 7, prevent the threaded tube 7 from rotating with the output shaft 6, and prompt the threaded tube 7 to always move laterally.
[0032] See also Figure 3 , characterized in that: a fixing ring 11 is fixedly connected to the inside of the housing 1, and the outer circumferential surface of the output shaft 6 is rotatably plugged into the inside of the fixing ring 11 to support and reinforce the output shaft 6 and increase the stability of the movement of the output shaft 6.
[0033] See also Figure 4 The outer circumferential surface of the slide rod 15 is fixedly connected to two limit plates 17, and the outer surface of each limit plate 17 is slidably connected to the inside of the fixed seat 14 to limit the slide rod 15, prevent the slide rod 15 from rotating, and increase the stability of the slide rod 15 movement.
[0034] See also Figure 4 A damper 18 is fixedly connected inside the fixed seat 14, and the other end of the damper 18 is fixedly connected to the bottom surface of the slide rod 15. The damper 18 is used to buffer and reduce shock on the roller 16, thereby increasing the stability of the detection device during movement.
[0035] See also Figure 4 A spring 19 is fixedly connected inside the fixed seat 14, and the other end of the spring 19 is fixedly connected to the bottom surface of the slide rod 15. The spring 19 enables the roller 16 to be in close contact with the inner wall of the oil pipeline to support the detection device, and cooperates with the damper 18 to buffer and reduce shock of the detection device.
[0036] See also Figure 1 , Figure 2 and Figure 3The outer circumference of the threaded tube 7 is fixedly connected with equidistantly arranged racks 8, and the outer circumference of the rotating rod 12 is fixedly sleeved with a gear 20. The gear 20 is meshed with the rack 8, so that the rack 8 can drive the rotating rod 12 to rotate through the gear 20 during the movement, thereby driving the roller 16 to be retracted and extended.
[0037] See also Figure 3 The outer circumferential surface of the output shaft 6 is provided with two sections of threaded structures, and the threaded tracks of the two sections of the threaded structures on the outer circumferential surface of the output shaft 6 are in opposite directions, so that the threaded tube 7 can move in relative directions, and then drive the rollers 16 at both ends to open and close in relative directions under the action of the rack 8 and the gear 20.
[0038] In the present embodiment, a detection device for internal flaw detection of oil pipelines is provided. In the process of moving, the rack 8 drives the rotating rod 12 to rotate under the action of the gear 20, so that the fixed frame 13 drives the roller 16 to be retracted and extended, so that the roller 16 can be in close contact with the inner wall of the oil pipeline, so as to support the detection device and drive the detection device to perform mobile detection, improve the detection efficiency, facilitate operation, and reduce costs. The problems of complex operation and low efficiency in existing internal flaw detection devices and methods of oil pipelines are solved, and some more advanced detection devices are expensive and difficult to meet actual detection needs.
[0039] It should be noted that the number of rollers 16 is 8, of which four rollers 16 are located at one end of the detection device, and the other four rollers 16 are located at the other end of the detection device, and the angle between the rollers 16 is 90 degrees.
[0040] The working principle of the above embodiment is as follows: when it is necessary to perform flaw detection on the inside of the oil pipeline, the detection device is placed in the oil pipeline, and then the motor 5 is started as a power to drive the threaded tube 7 to move in the relative direction through the output shaft 6. The threaded tube 7 drives the rotating rods 12 at both ends to rotate in the relative direction through the rack 8 and the gear 20. Then the fixed frame 13 drives the roller 16 to rotate and open through the fixed seat 14 and the slide bar 15. After the roller 16 contacts the inner wall of the oil pipeline, it will squeeze the spring 19. The spring 19 will apply a reaction force through its own elastic force, so that the roller 16 is in close contact with the inner wall of the oil pipeline to support the detection device. After that, the external motor connected to the roller 16 can be started to drive the detection device to move and detect. The staff can illuminate the inside of the oil pipeline through the searchlight 3 and observe the inside of the oil pipeline through the camera 4 to observe whether there is corrosion and wear on the inner wall of the oil pipeline. The spring 19 and the damper 18 can buffer and reduce shock for the detection device in operation, increase the stability of the detection device, and improve the detection efficiency.
