Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to an adjustable pipeline detection device. Background Art

[0002] Pipeline inspection mainly involves measuring and monitoring the outer diameter of the pipeline. The outer diameter of the pipeline is a key parameter for evaluating its load-bearing capacity, fluid flow characteristics and overall structural integrity. Accurately measuring the outer diameter is essential for the design, installation and maintenance of pipelines. Traditional measurement methods include: Mechanical measurement: Manual measurement using tools such as calipers and measuring tapes, which is suitable for small-scale inspections, but is inefficient and easily affected by human factors. Optical measurement: Using optical equipment such as laser rangefinders to measure the outer diameter has high accuracy, but may be interfered with in complex environments.

[0003] Among many existing technologies, Chinese patent application CN211783213U discloses an outer diameter detection device, including a rotating motor, a bracket, a conveyor belt, and a pipeline outer diameter detection component, wherein a driving shaft roller is rotatably installed on one side of the bracket, the rotating motor is drivingly connected to the driving shaft roller, the rotating motor is fixedly installed to the bracket, and a driven shaft roller is rotatably installed on the other side of the bracket, the driving shaft roller and the driven shaft roller are connected through the conveyor belt, and two groups of cylinders are symmetrically installed on the upper end of the bracket along the conveying direction of the conveyor belt, and the two groups of pipeline outer diameter detection components are respectively installed on the upper ends of the two groups of cylinders.

[0004] However, this patent application uses the method of observing the markings on the outer wall of the pipeline to determine the outer diameter of the pipeline. If the pipeline size is lower than the qualified threshold, there will be no markings. If the pipeline size is within the qualified threshold, the first spring clip will contact the pipeline and leave a mark, while the second spring clip will not contact and leave a mark. The qualified product will have only one mark. If the pipeline size exceeds the qualified threshold, both the first spring clip and the second spring clip will contact the pipeline and leave a mark. During the detection process, the pipeline cannot be marked at multiple angles. Detection at a single angle increases the risk of false detection and missed detection. Multi-angle detection cannot be performed, and potential problems may be missed due to local detection, causing problems in the use of subsequent products.

[0005] Based on this, the utility model designs an adjustable pipeline detection device to solve the above problems. Utility Model Content

After the connecting plate 311 is adjusted to the corresponding position, the inner rotating shaft 315 is in contact with and rotatably connected to the outer wall of the PE pipe. When the outer diameter of the PE pipe is in the normal size state, the rotating shaft 315 will drive the C-shaped mounting plate 314 to squeeze the transmission rod 313. The transmission rod 313 transmits the force to the pressure sensor 316. At this time, the force detected by the pressure sensor 316 is within the set fixed value range. When the outer diameter of the PE pipe is smaller than the normal size, the force transmitted by the transmission rod 313 decreases or no force is transmitted, and the force detected by the pressure sensor 316 is smaller than the normal fixed value range, so it can be detected that the outer diameter of the PE pipe is too small. When the outer diameter of the PE pipe is larger than the normal size, the force transmitted by the transmission rod 313 increases, and the force detected by the pressure sensor 316 is larger than the normal fixed value range, so it can be detected that the outer diameter of the PE pipe is too large.
