Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure pipeline remote detection, and more specifically, to a high-pressure pipeline remote detection device. Background Art

[0002] High-pressure pipelines refer to pipelines that can withstand higher pressures and are usually used to transport gases or liquids. According to chemical standards, pipelines that withstand pressures ≥16MPa are called high-pressure pipelines, which are mainly used in specific environments such as high-pressure steam equipment, chemical high-temperature and high-pressure pipelines, pressure vessels in power plants and nuclear power plants, and high-pressure boiler accessories. High-pressure pipelines are made of various materials, including high-quality carbon structural steel, alloy structural steel, etc., with specific steel grades such as 20g, 20mng, 15mog, etc. In addition, the definition of high-pressure pipelines also includes a maximum working pressure greater than or equal to 0.1MPa (gauge pressure), and the medium is gas, liquefied gas, steam, or flammable, explosive, toxic, corrosive liquids with a maximum working temperature higher than or equal to the standard boiling point.

[0003] At present, in the use process of high-pressure pipelines, as the use time increases, due to various external factors or use wear and tear, personnel are required to regularly inspect the high-pressure pipelines to avoid pipeline leakage caused by corrosion, impact of external objects, and aging of the high-pressure pipelines. However, in actual use, due to the long length of the pipeline, its efficiency is relatively slow under manual inspection. Therefore, there is a detection mechanism used inside the pipeline. However, under this detection method, although it can timely detect whether there is damage and leakage inside the pipeline, it is still impossible to detect the damage and aging degree of the outside of the pipeline, and the phenomenon that no leakage occurs, which prevents personnel from replacing the pipeline before the pipeline leaks, and still has certain safety hazards. For this reason, this scheme proposes a high-pressure pipeline remote detection device. Summary of the invention

Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0023] See also Figure 1-Figure 6 A high-pressure pipeline remote detection device includes a detection instrument 1, and connectors 2 are installed on the left and right sides of the detection instrument 1. A plurality of evenly distributed limiting mechanisms 3 are provided on the inner side of the connector 2. One end of the limiting mechanism 3 is in rolling contact with the high-pressure pipeline. An intelligent vehicle 4 is installed on the side end of one of the connectors 2. A centering piece 5 is provided on the side end of the intelligent vehicle 4. The centering piece 5 is sleeved on the outer side of the high-pressure pipeline.

[0024] During use, this solution avoids the low efficiency of manual inspection in the prior art and the inability to detect the aging of the external pipeline and the phenomenon that the pipeline needs to be replaced in advance when inspecting inside the pipeline. Therefore, in this embodiment, a remote inspection device that detects on the outside of the pipeline and has intelligent automation is adopted, so that personnel do not need to perform inspections one by one on the long pipeline, thereby speeding up the inspection efficiency. At the same time, it can also be applied to multiple types of pipelines, so that the aging and damaged pipelines can be replaced in advance, avoiding the replacement after the subsequent leakage, and enhancing the safety during use. In addition, under remote inspection, the pipeline can still be inspected in rain or other bad weather. When in use, the personnel arrange multiple sets of detection instruments 1 and connectors 2 on the upper, lower, left and right sides of the pipeline respectively, and then place the detection instruments 1 and connectors 2 to the outside of the pipeline under the connection limit between multiple limit mechanisms 3, and one end of the limit mechanism 3 is fitted with the pipeline, and finally the smart car 4 is fixed to one side of the connector 2, and the centering piece 5 is set to the outside of the smart car 4. When in use later, the personnel only need to remotely drive the smart car 4 so that the smart car 4 pushes the connector 2 as a whole, and the limit mechanism 3 rolls and pushes on the surface of the pipeline, so that the detection instrument 1 can detect the outer diameter of the pipeline in all directions, and check whether a certain part of the pipeline as a whole is aging, damaged, and needs to be replaced, which greatly improves the efficiency of existing detection, and also avoids the safety hazard of replacement after leakage; As the smart car 4 moves, when the limit mechanism 3 passes through the flange head of the pipeline or other obstacles, the limit mechanism 3 and the smart car 4 can automatically adjust the position up and down and take shock-proof measures to ensure the stability of the detection instrument 1 during the detection process until the detection of a high-pressure pipeline is completed. Similarly, the smart car 4 can also pull the detection instrument 1 and the connector 2 as a whole through reverse drive, so as to return to the initial position again.

[0026] More specifically, the limiting mechanism 3 includes two groups of symmetrically distributed positioning members 31 and positioning members 32. One group of positioning members 31 is installed on the inner walls of the connecting plate 21 at the front and rear sides, and the other group of positioning members 32 is installed on the inner walls of the connecting plate 21 at the upper and lower sides.

[0030] When testing the pipeline, the present solution first places the four connectors 2 on the upper, lower, left and right sides of the pipeline, wherein the arc plate 311 is fixedly connected to the inner wall of the connector plate 21 on one side through the shock absorber 312, and the arc limit buckles 316 on the front and rear sides are respectively inserted into the receiving grooves 3 of the arc limit sleeves 325 on the upper and lower sides, and then the threaded plugs 326 are inserted into the through holes between the two to fix the two, so that the four connectors 2 are located on the upper, lower, left and right sides of the pipeline, and at the same time, the roller 314 is connected to the pipeline. The surface is fitted, and finally, under the push of the smart car 4, the detection instrument 1, the connector 2, and the limit mechanism 3 can be moved as a whole. During the detection process of the pipeline, when it moves to the flange or a position with an obstacle, the roller 1 314 is in a spherical shape, and due to the resistance of the flange or the obstacle, the damping spring 1 313 and the shock absorber 1 312 are contracted, so that when it passes over the obstacle or flange, it can also ensure that the detection instrument 1 can stably perform the detection operation without causing excessive shaking; During use of the present solution, the corrugated curtain 22 is made of flexible material, so that when the pipeline passes through a curve, its overall deformation direction can also be stretched, thereby adapting to continuous movement and detection operations on a curved path.
