Description

Technical Field

[0002] Natural gas is a type of flammable gas that exists in nature. It is mainly composed of hydrocarbons and contains non-hydrocarbon gases. It is a fossil fuel. Natural gas requires the use of natural gas pipelines for transportation after extraction. Before use, such pipelines must ensure that their welding points are in a seamless state to avoid natural gas leakage.

[0003] Patent specification CN221301035U discloses a natural gas pipeline leakage detection device, comprising a natural gas pipeline and a mounting ring, a detection mechanism, and a wireless infrared leak detection device, a fixed cylinder, a slide plate, a fixed rod, a fixed plate, a spring, and an air supply assembly. Multiple wireless infrared leak detection devices are symmetrically fixedly connected to the inner wall of the mounting ring. Multiple fixed cylinders are symmetrically fixedly connected to the inner wall of the mounting ring. Each of the multiple fixed cylinders is sealed and slidably connected to the inner wall of each slide plate. The lower end of the slide plate is fixedly connected to a fixed rod. The lower end of the fixed rod passes through the lower end of the fixed cylinder and is fixedly connected to the fixed plate. Springs are sleeved on the side walls of the fixed rods.

[0004] When in use, the detection device clamps the pipeline through a fixing plate, and evenly installs multiple wireless infrared leak detection devices along the inner side of the mounting ring at the clamping position. The wireless infrared leak detection devices are used to detect pipeline gaps. However, the disadvantage is that during the detection process, this scheme can only detect a very short part of the pipeline within the mounting ring, and the detection position is limited by the number of installed infrared leak detection devices. At the same time, there are gaps between each leak detection device, so the detection pipeline has insufficient coverage.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, a natural gas pipeline detection device that is easy to fix includes a gear ring 1, one side of the gear ring 1 is fixedly connected to an outer fixed ring 2, and the other side is fixedly connected to a limit ring 3, six locking members 4 are evenly installed on the side of the outer fixed ring 2, and a pipe 5 is sandwiched between each locking member 4, a movable member 6 is installed between one side of the limit ring 3, a shift assembly 7 is installed on one side of the movable member 6, and the shift assembly 7 drives the movable member 6 to rotate circumferentially along the limit ring 3, a transverse movement assembly 8 is installed on one side of the movable member 6, and a detection assembly 9 is installed on the bottom side of the transverse movement assembly 8, and the transverse movement assembly 8 is used to drive the detection assembly 9 to laterally detect the pipe 5;

[0025] It should be noted that the locking member 4 includes a screw 41 threadedly connected to the outer fixing ring 2, one end of the screw 41 is fixedly connected to the handle 42, and the other end is rotatably connected to the arc plate 43, the inner surface of the arc plate 43 is in contact with the outer surface of the pipe 5, and the axial center line of each screw 41 intersects with the axial center line of the pipe 5. Before inspecting the pipe 5, the arc plate 43 is moved by rotating the handle 42 until each arc plate 43 clamps and fixes the pipe 5 along the circumferential side of the pipe 5, so as to prevent the pipe 5 from shaking and shifting during subsequent inspection.

[0026] like Figure 1 and Figure 3 As shown, the movable part 6 includes a hanging plate 61. Two guide wheel groups 62 are installed on the side of the hanging plate 61 close to the limiting ring 3. Two guide wheels 63 are installed on one side of the guide wheel group 62, and the extension line of the axis connecting the two guide wheels 63 intersects the axis of the pipe 5. Guide rails 10 are provided on both sides of the limiting ring 3. The guide rails 10 are in rolling connection with the guide wheels 63 on the adjacent sides. Since both ends of one side of the hanging plate 61 clamp the inner and outer sides of the limiting ring 3 through the guide wheel group 62, the movable part 6 can perform circular motion along the limiting ring 3 under the limited rolling of the four guide wheels 63.

[0027] The shift assembly 7 includes a drive motor 71 fixedly connected to one side of the suspension plate 61. The output end of the drive motor 71 passes through the suspension plate 61 and is equipped with a driving gear 72. The driving gear 72 is engaged with the gear ring 1. Since the movable part 6 can make a circular motion along the limit ring 3, and the drive motor 71 is installed on the movable part 6, and the gear ring 1 and the limit ring 3 are fixedly connected, when the drive motor 71 is driven, the driving gear 72 and the gear ring 1 are driven by the motor to rotate, thereby realizing the rotation control of the movable part 6.

[0028] like Figure 1 、 Figure 2 and Figure 4 As shown, the transverse movement assembly 8 includes a second drive motor 81 mounted on one side of the suspension plate 61. Two guide rods 82 are fixedly connected to one side of the suspension plate 61. A transmission belt 83 is installed between the two ends of the two guide rods 82. The transmission belt 83 is connected to the output end of the second drive motor 81. A slider 84 is fixedly connected to one side of the transmission belt 83. The slider 84 is slidably connected to the two guide rods 82. The detection assembly 9 is mounted on the bottom surface of the slider 84.

[0029] The detection assembly 9 includes a support frame 91 fixedly connected to one side of the slider 84, a rotating frame 92 is installed in the middle of the support frame 91, an infrared thermal imager 93 is installed in the middle of the rotating frame 92, and a micro motor 94 is installed on one side of the support frame 91. The output end of the micro motor 94 is fixedly connected to one side of the rotating frame 92;

[0030] It should be noted that when the driving motor 81 rotates, it drives the transmission belt 83 to rotate, and the slider 84 fixedly connected to the transmission belt 83 moves in the horizontal direction under the limit of the two guide rods 82. During the movement, the detection component 9 installed at the bottom of the slider 84 moves synchronously, thereby detecting the lateral position of the pipe 5, and during the inspection process, the micromotor 94 drives the rotating frame 92 to rotate by rotating to change the shooting direction of the infrared thermal imager 93, thereby improving the detection coverage. Therefore, after the lateral position is detected with high coverage, the circumferential movement of the movable part 6 is controlled by the shifting component 7, and the transverse movement component 8 is installed on one side of the movable part 6. The cross-movement detection formed by the circumferential rotation and lateral displacement enables the device to perform a full coverage comprehensive detection of the side surfaces of the pipe 5, that is, the detection coverage area is improved by increasing the detection length and circumferential detection.

[0031] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
