Description

Technical Field

[0001] This utility model relates to the field of oil and gas long-distance pipeline inspection technology, and in particular to a surface crack detection device for oil and gas long-distance pipelines. Background Technology

[0002] Long-distance pipelines refer to pipelines used to transport commodity media between production sites, storage facilities, and user units. Oil and gas long-distance pipeline systems are pipeline systems used to transport oil and gas and oil and gas products. They are mainly composed of oil pipelines, oil stations, and other auxiliary related equipment. They are one of the main equipment in the oil and gas storage and transportation industry, and also the most important equipment for transporting crude oil and oil and gas products. During the long-term use of oil and gas long-distance pipelines, cracks may appear on the surface of the oil pipeline due to the pressure inside the pipeline. It is necessary to use detection devices to detect cracks on the surface of oil and gas long-distance pipelines.

[0003] Existing detection devices use infrared detection cameras to detect cracks on the surface of oil and gas pipelines. However, infrared detection cameras have some shortcomings in actual detection: the surface of oil and gas pipelines may be covered with a thick layer of dirt, which can cover the cracks and interfere with and weaken the thermal radiation signal in the crack area. This can cause the infrared detection camera to fail to accurately receive the thermal radiation information in these areas, thus affecting the accuracy of the detection and potentially leading to deviations or omissions in the detection results.

[0004] Therefore, a surface crack detection device for long-distance oil and gas pipelines is needed to solve the above problems. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a surface crack detection device for long-distance oil and gas pipelines, which can clean the dirt layer on the surface of oil and gas pipelines and improve the detection accuracy. It includes: a main unit 100, which includes a frame 101, a rotating wheel 102 and two sets of rotating wheels 103.

[0032] Two sets of crack detection mechanisms 300 are set on one side of the rotating wheel 103 for detecting the surface of long-distance oil and gas pipelines;

[0033] Two sets of cleaning mechanisms 400, located on the other side of the rotating wheel 103, are used to clean the surface of the long-distance oil and gas pipeline. Each set includes a cleaning component and a support component, the support component being used to fix the cleaning component; and...

[0034] The spacing adjustment mechanism 200 is used to adjust the spacing between the two sets of crack detection mechanisms 300 and the two sets of cleaning mechanisms 400.

[0035] In use, the device is placed on the oil and gas pipeline. First, the spacing adjustment mechanism 200 drives the two rotating wheels 103 to move and press against the side wall of the oil and gas pipeline. The arrangement of the rotating wheels 102 and 103 facilitates the movement of the device on the oil and gas pipeline. At the same time, the spacing adjustment mechanism 200 brings the two sets of crack detection mechanisms 300 and the two cleaning components closer to the oil and gas pipeline. The cleaning components first clean the dirt layer on the surface of the oil and gas pipeline, and then the crack detection mechanism 300 performs crack detection, thereby improving the accuracy of the detection and preventing deviations or omissions in the detection results.

[0036] Example 2

[0037] Reference Figure 1 - Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the multiple sets of crack detection mechanisms 300 all include mounting plates 302. Each mounting plate 302 is fixedly connected to the rotating wheel 103 through a connecting plate 301. Multiple infrared detection cameras 303 are fixedly installed on the inner sidewalls of the two mounting plates 302.

[0038] Furthermore, each of the multiple cleaning components includes a geared motor 404 and an arc-shaped plate 406. A cleaning wipe 407 can be detachably installed on the inner side of each arc-shaped plate 406. A T-slot 4061 is opened on one side of each arc-shaped plate 406. A toothed plate 408 is fixedly installed on the outer side of each arc-shaped plate 406. A drive gear 405 is meshed on each toothed plate 408. A rotating shaft is fixedly inserted at the center of each drive gear 405. One end of the rotating shaft is fixedly connected to the output end of the geared motor 404.

[0039] It should be noted that the teeth of the drive gear 405 should fit tightly with the tooth grooves on the gear plate 408 to ensure that the transmission accuracy meets the usage conditions of this utility model; the cleaning wipe 407 and the arc plate 406 are connected by a detachable method, such as Velcro, which makes it easy to replace the cleaning wipe 407 and ensures that the cleaning wipe 407 always maintains good cleaning ability.

[0040] Furthermore, each of the multiple support components includes a support plate 402. One side of each support plate 402 is fixedly connected to the movable plate 206 via a horizontal plate 401. The other side of each support plate 402 is rotatably connected to a T-shaped rod 409. The other end of each T-shaped rod 409 is disposed in a T-shaped groove 4061 and is slidably connected to the T-shaped groove 4061.

[0041] Furthermore, a protective cover 403 is fitted on each of the multiple drive gears 405, and each protective cover 403 is fixedly connected to the support plate 402. Multiple reduction motors 404 are fixedly connected to the support plate 402.

[0042] It should be noted that the protective cover 403 serves to protect the drive gear 405. Similarly, the protective cover 403 can be fitted onto the gear plate 408 according to actual needs.

[0043] Furthermore, a controller 105 is installed on one side of the frame 101, and a power supply box 104 is provided on the other side of the frame 101. The power supply box 104 is fixedly connected to the fixed box 201 through the base plate 1041.

[0044] It should be noted that the controller 105 is used to control the entire device, and the power supply box 104 is used to supply power to the device. Since the controller 105 and the power supply box 104 are common devices and belong to existing mature technologies, their electrical connection relationship and specific circuit structure will not be described here.

[0045] In use, the controller 105 synchronously starts two geared motors 404, whose outputs drive the drive gears 405 to rotate. The drive gears 405 and the toothed plate 408 drive the two arc plates 406 to rotate in the same direction and synchronously, which in turn drives the cleaning wipe 407 to rotate and clean the dirt layer on the surface of the oil and gas pipeline. Afterwards, the infrared detection camera 303 in the crack detection mechanism 300 detects the outside of the oil and gas pipeline.

[0046] Preferably, the controller 105 controls the geared motor 404 to work in a reciprocating manner of 2 revolutions in the forward direction and 2 revolutions in the reverse direction, so that the two arc plates 406 rotate in the forward and reverse directions, and the angle of a single rotation of the arc plate 406 is 0-90°.

[0047] Example 3

[0048] Reference Figure 3 and Figure 4 This is the third embodiment of the present invention. Unlike the previous embodiment, the spacing adjustment mechanism 200 includes a fixed box 201 fixedly embedded in the inner wall of the frame 101. A worm gear 202 is rotatably connected to the inner wall of the fixed box 201. A worm wheel 203 is meshed on the worm gear 202. A forward and reverse lead screw 204 is fixedly inserted at the center of the worm wheel 203. Two lead screw sleeves 205 are meshed on the forward and reverse lead screw 204. A moving plate 206 is fixedly connected to the lower end of each lead screw sleeve 205. The spacing adjustment mechanism 200 also includes a limiting rod 207 fixedly connected to the frame 101. Both moving plates 206 are slidably sleeved on the limiting rod 207.

[0049] It should be noted that the worm gear 202 and the worm wheel 203 have a reverse self-locking function, which improves the stability of the device when it moves on the oil and gas pipeline.

[0050] Furthermore, the rotating wheel 102 is fixedly connected to the lower end of the fixed box 201, the upper end of the worm gear 202 passes through the fixed box 201 and is fixedly connected to a knob, the worm gear 202 is rotatably connected to the inner wall of the fixed box 201, and both ends of the forward and reverse screws 204 are rotatably connected to the frame 101, and the forward and reverse screws 204 are rotatably connected to the inner wall of the fixed box 201.

[0051] In use, turning the knob drives the worm gear 202 to rotate, which in turn drives the worm wheel 203 to rotate. The worm wheel 203 then drives the forward and reverse lead screws 204 to rotate, which in turn drives the lead screw sleeve 205 to move. The lead screw sleeve 205 and the moving plate 206 together move the two rotating wheels 103 to abut against the side wall of the oil and gas pipeline, and simultaneously move the two sets of crack detection mechanisms 300 and the two sets of cleaning mechanisms 400 closer to the oil and gas pipeline.

[0052] In summary, an oil and gas pipeline surface crack detection device improves detection accuracy and prevents deviations or omissions in the detection results by cleaning the dirt layer on the surface of the oil and gas pipeline through a cleaning component during crack detection.

[0053] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
