Description

Technical Field

[0001] This utility model relates to the field of gas pipeline inspection, and in particular to a gas pipeline anti-corrosion layer electric spark detection and positioning device. Background Technology

[0002] After the anti-corrosion layer is applied to the gas pipeline, it needs to be tested by spark testing to determine whether there are any defects such as leaks or pinholes, and to determine whether the anti-corrosion layer is qualified.

[0003] In existing technologies, spark testing devices are widely used. For example, patent application CN209979184U describes a device that uses a base and a spark tester probe. Two positioning rods are fixedly connected to the upper side of the base, and guide blocks are slidably mounted on the positioning rods. An electric telescopic rod is fixedly connected to the guide blocks, and a tester mounting plate is fixedly connected to the end of the electric telescopic rod. The mounting plate has bolt holes, and the mounting plate is fixedly mounted on the spark tester probe by bolts. One end of a connecting rod is hinged to the guide block. By setting up a control panel, an electric telescopic rod, and a servo motor, the horizontal position and height of the spark tester probe can be adjusted. This device can meet the installation requirements of different sizes of spark testers when testing pipes of different diameters. The device has a wide range of applications and a high degree of automation, eliminating the need for cumbersome manual operation.

[0004] However, this type of testing device still has some shortcomings. First, the threaded rod used for adjustment is located at the bottom of the spark tester. When testing the pipeline, dust and impurities on the pipeline surface are very easy to fall off and accumulate on the threaded rod, thus affecting the stability of the device's operation. Second, the device lacks an effective self-locking structure. After the spark tester is adjusted to a suitable height, its position is prone to shift during subsequent use due to factors such as uneven pipeline surface and vibration during testing.

[0005] Therefore, it is necessary to provide a spark detection and positioning device for the anti-corrosion layer of gas pipelines to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a gas pipeline anti-corrosion layer electric spark detection and positioning device, which solves the problems of dust accumulation on the threaded rod affecting operational stability and the lack of a self-locking structure causing the detection position to easily shift in existing electric spark detection devices.

[0007] To solve the above-mentioned technical problems, this utility model provides a gas pipeline anti-corrosion layer electric spark detection and positioning device, comprising:

[0008] Base plate;

[0009] A support frame is fixedly installed on the top of the base plate. An electric spark detector body is provided on the inner side of the support frame. Both sides of the electric spark detector body are fixedly installed with drive telescopic components. A slider is fixedly installed on the outer side of the drive telescopic components. A first rotating seat is fixedly installed at the bottom of the slider. A connecting rod is rotatably connected inside the first rotating seat. A second rotating seat is rotatably connected at the bottom of the connecting rod.

[0010] A protective frame is fixedly installed on the inner side of the support frame. A movable groove is provided at the bottom of the protective frame. A film is fixedly installed on both sides of the inner side of the movable groove. A driving component is fixedly installed on the front of the protective frame. A rotating shaft is fixedly installed at the output end of the driving component. A worm gear is fixedly installed on the outer side of the rotating shaft. A worm wheel meshes with the bottom of the worm gear. Threaded rods are fixedly installed on both sides of the worm wheel. A movable block is threadedly connected to the outer side of the threaded rod. A movable frame is fixedly installed at the bottom of the movable block. The top of the movable frame is fixedly installed at the bottom of the second rotating seat.

[0011] Preferably, the support frame has grooves on both sides, and the slider is slidably connected to the inner side of the groove.

[0012] Preferably, the movable block is positioned between the two films, and the movable frame is slidably connected to the outer side of the protective frame.

[0013] Preferably, one end of the threaded rod is rotatably connected to one side of the inner side of the protective frame.

[0014] Preferably, a control panel is fixedly mounted on the front of the support frame.

[0015] Preferably, rollers are fixedly installed around the bottom of the base plate.

[0016] Preferably, a shield is fixedly installed on the front of the protective frame, and the shield is disposed on the outer side of the drive component.

[0017] Compared with related technologies, the spark detection and positioning device for the anti-corrosion layer of gas pipelines provided by this utility model has the following advantages:

[0018] This utility model provides a spark detection and positioning device for the anti-corrosion layer of gas pipelines. By creating a movable groove at the bottom of the protective frame and installing a film on the inner side of the groove, dust and impurities falling during gas pipeline inspection accumulate at the top of the protective frame, preventing them from accumulating on the threaded rod and affecting its normal operation, thus increasing the stability of the device. Furthermore, a drive component rotates the shaft, which in turn drives the worm gear and worm wheel to mesh, thereby rotating the threaded rod. When the spark detector body is adjusted to a suitable height, the meshing structure of the worm gear and worm wheel locks the threaded rod in place. Even when affected by external vibrations or uneven pipe surfaces during inspection, the threaded rod will not easily rotate, ensuring the fixed position of the spark detector and preventing positional deviation during inspection.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an electric spark detection and positioning device for the anti-corrosion layer of a gas pipeline provided by this utility model;

[0027] Figure 2 for Figure 1 The diagram shows a front cross-sectional view of the protective frame. Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. A gas pipeline anti-corrosion layer spark detection and positioning device includes: a base plate 1;

[0028] A support frame 2 is fixedly installed on the top of the base plate 1. An electric spark detector body 4 is provided on the inner side of the support frame 2. Both sides of the electric spark detector body 4 are fixedly installed with drive telescopic components 31. A slider 3 is fixedly installed on the outer side of the drive telescopic component 31. A first rotating seat 32 is fixedly installed at the bottom of the slider 3. A connecting rod 33 is rotatably connected inside the first rotating seat 32. A second rotating seat 34 is rotatably connected at the bottom of the connecting rod 33.

[0029] A protective frame 6 is fixedly installed on the inner side of the support frame 2. A movable groove 61 is provided at the bottom of the protective frame 6. A film 62 is fixedly installed on both sides of the inner side of the movable groove 61. A driving component 63 is fixedly installed on the front of the protective frame 6. A rotating shaft 64 is fixedly installed at the output end of the driving component 63. A worm gear 65 is fixedly installed on the outer side of the rotating shaft 64. A worm wheel 66 is engaged at the bottom of the worm gear 65. Threaded rods 67 are fixedly installed on both sides of the worm wheel 66. A movable block 68 is threadedly connected to the outer side of the threaded rod 67. A movable frame 69 is fixedly installed at the bottom of the movable block 68. The top of the movable frame 69 is fixedly installed at the bottom of the second rotating seat 34.

[0030] The support frame 2 has grooves 21 on both sides, and the slider 3 is slidably connected to the inner side of the grooves 21.

[0031] The movable block 68 is positioned between the two films 62, and the movable frame 69 is slidably connected to the outer side of the protective frame 6.

[0032] One end of the threaded rod 67 is rotatably connected to one side of the inner side of the protective frame 6.

[0033] The control panel 5 is fixedly installed on the front of the support frame 2.

[0034] Rollers 11 are fixedly installed around the bottom of the base plate 1.

[0035] When in use, the films 62 installed on both sides of the inner side of the moving slot 61 clamp the moving block 68 in the middle. At this time, when the moving block 68 is not moving, one side of the two films 62 contacts each other, thereby blocking the dust and preventing the dust from entering the inner side of the protective frame 6.

[0036] The film 62 is made of rubber. When the moving block 68 moves, the film 62 can deform, thereby avoiding affecting the normal movement of the moving block 68.

[0037] The inner side of the movable frame 69 is attached to the outer side of the protective frame 6. When the threaded rod 67 rotates, the movable frame 69 can slide on the outer side of the protective frame 6, thereby limiting the movable frame 69 and increasing the stability of the movable frame 69 when it moves.

[0038] The drive component 63 uses a stepper motor, and the drive telescopic component 31 is an electric telescopic rod.

[0039] The working principle of the electric spark detection and positioning device for the anti-corrosion layer of gas pipelines provided by this utility model is as follows:

[0040] When adjusting the height of the spark tester body 4 during use, the operator can control the drive component 63 via the control panel 5. This activates the drive component 63, which in turn drives the worm gear 65 to rotate via the rotating shaft 64. The worm gear 65 then drives the worm wheel 66 to rotate, which in turn drives the threaded rod 67 to connect with the moving block 68. This allows the two moving blocks 68 to move relative to each other or back to back. The moving frame 69, the first rotating seat 32, the connecting rod 33, and the second rotating seat 34 transmit power to each other, thereby adjusting the height of the spark tester body 4 via the slider 3. Afterward, the control panel 5 controls the extension and retraction of the two drive telescopic components 31 to adjust the horizontal position of the spark tester body 4.

[0041] Compared with related technologies, the spark detection and positioning device for the anti-corrosion layer of gas pipelines provided by this utility model has the following advantages:

[0042] By creating a movable groove 61 at the bottom of the protective frame 6 and installing a film 62 on the inner side of the movable groove 61, dust and impurities falling during gas pipeline inspection will accumulate on the top of the protective frame 6, preventing them from accumulating on the threaded rod 67 and affecting its normal use, thus increasing the stability of the device during operation. Furthermore, the drive component 63 drives the rotating shaft 64 to rotate, which in turn drives the worm gear 65 to mesh with the worm wheel 66, thereby driving the threaded rod 67 to rotate. When the spark detector body 4 is adjusted to a suitable height, the meshing structure of the worm gear 65 and the worm wheel 66 can lock the threaded rod 67. Even if it is affected by external vibrations or uneven pipe surfaces during the inspection process, the threaded rod 67 will not easily rotate, ensuring the fixed position of the spark detector and preventing positional deviation during the inspection process.

[0046] The working principle of the electric spark detection and positioning device for the anti-corrosion layer of gas pipelines provided by this utility model is as follows:

[0048] Compared with related technologies, the spark detection and positioning device for the anti-corrosion layer of gas pipelines provided by this utility model has the following advantages:
