Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to an oil and gas pipeline deformation detection device. Background Technology

[0002] Utility model patent CN213932393U discloses a geometric deformation detection device for oil and gas pipelines. The device includes a detection cylinder with an installation cavity inside. Two sets of drive motors are symmetrically arranged at the left and right ends of the installation cavity. A turntable is fixed to the horizontal output end of each drive motor. Support rods are symmetrically arranged on the side of the turntable away from the drive motors, and casters are mounted on the support rods. A gas spring is hinged to the middle of the support rod, and the other end of the gas spring is hinged to the turntable. Two sets of detection rods are symmetrically arranged on the side of the turntable near the drive motors. A laser ranging transmitter is installed on the side wall of one detection rod, and a laser ranging receiver is installed on the side wall of the other detection rod. The design of the support rods, gas springs, and casters ensures that the casters remain in contact with the inner wall of the oil and gas pipeline to be inspected, improving detection accuracy and reducing detection errors. The design of the drive motors and turntable facilitates precise local inspection of the oil and gas pipeline.

[0003] During long-term use, oil and gas pipelines are subjected to external pressure, which can cause the inner wall of the pipeline to bulge. Laser detection can only detect the two ends of the laser, which can easily lead to missed detections. Traditional equipment uses a drive motor to rotate the laser device for rotational detection, but it cannot maintain a stable state when the detection device is stopped. Utility Model Content

[0006] Preferably, the parking assembly includes a connecting block fixedly connected to the right side of the detection cylinder, and the surface of the connecting block is provided with reinforcing ribs.

[0007] Preferably, a telescopic rod is fixedly connected to one side of the connecting block, and a protective sleeve is provided on the surface of the telescopic rod.

[0008] Preferably, a stabilizing plate is fixedly connected to one end of the telescopic rod, and the surface of the stabilizing plate is provided with reinforcing ribs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides two technical solutions:

[0024] Example 1: An oil and gas pipeline deformation detection device includes a detection cylinder 1. A detection component 2 for detecting oil and gas pipeline deformation is fixedly connected to the left side of the detection cylinder 1. The detection component 2 includes a central block 21 fixedly connected to the left side of the detection cylinder 1. Four arc-shaped frames 22 are fixedly connected to the surface of the central block 21. A fixing frame 23 is fixedly connected to one side of the inner wall of each arc-shaped frame 22. A support plate 24 is fixedly connected to one side of the surface of the fixing frame 23. A mounting plate 25 is movably connected to one side of the support plate 24. A baffle 26 is fixedly connected to the surface of the mounting plate 25. Bolts 27 penetrate the surface, and sensors 28 are fixedly connected to one side of the mounting plate 25. There are two sensors 28, which are piezoelectric pressure sensors. Parking assembly 3 is fixedly connected to the right side of the detection cylinder 1. Through the setting of the detection assembly 2, the device uses multiple independent sensors 28 to detect the inner wall of the oil and gas pipeline. Because of the independent setting, it can quickly determine which part of the pipeline is deformed, effectively avoiding missed detection. The sensors 28 have a long working time. By rotating the bolts 27 on the surface of the baffle 26, the sensors 28 and the mounting plate 25 can be directly disassembled and replaced, which is convenient for the staff to operate quickly.

[0025] Example 2 differs from Example 1 in that: an oil and gas pipeline deformation detection device, the parking assembly 3 includes a connecting block 31 fixedly connected to the right side of the detection cylinder 1, the surface of the connecting block 31 is provided with reinforcing ribs, a telescopic rod 32 is fixedly connected to one side of the connecting block 31, the surface of the telescopic rod 32 is provided with a protective sleeve, a stabilizing plate 33 is fixedly connected to one end of the telescopic rod 32, the surface of the stabilizing plate 33 is provided with reinforcing ribs, an electromagnetic chuck 34 is fixedly connected to one side of the stabilizing plate 33, the surface of the electromagnetic chuck 34 is powered by DC, a power wheel 4 is fixedly connected to the inner wall of the detection cylinder 1, a battery box 5 is fixedly connected to the back of the inner wall of the detection cylinder 1, and a sealing cover is hinged to the surface of the detection cylinder 1. Through the setting of the parking assembly 3, the device can be directly attracted to the inner wall of the pipeline by the electromagnetic chuck 34, thereby fixing the device to the inner wall of the oil and gas pipeline, and the telescopic rod 32 directly raises the electromagnetic chuck 34, so that the attraction is more thorough, ensuring that the device can be stably parked on the inner wall of the pipeline when it stops, and avoiding random sliding.

[0026] The surface of the drive wheel 4 is provided with an anti-slip surface, and one end of the drive wheel 4 is connected to the output end of the motor in the detection cylinder 1.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, select an arc-shaped frame 22 of appropriate diameter so that both sides of the arc-shaped frame 22 can fit against the inner wall of the pipe. Insert one side of the arc-shaped frame 22 into the inner wall of the pipe, turn on the battery box 5 in the detection cylinder 1 to supply power, and the power wheel 4 drives the entire device to move. Once the top of the arc-shaped frame 22 encounters an uneven convex surface, the arc-shaped frame 22 will be squeezed, and the sensor 28 will be triggered to alarm. When the sensor 28 needs to be replaced after long-term operation, rotate the bolt 27 to separate the bolt 27 from the fixing frame 23, and then pull it outward. The mounting plate 25 and the sensor 28 can be directly removed from the fixing frame 23. After stopping the forward movement, raise the telescopic rod 32. The stabilizing plate 33 drives the electromagnetic chuck 34 to fit against the inner wall of the pipe, and the entire device is fixed. When the device is finished using, restore the device to its original state.
