Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline settlement detection, in particular to a gas pipeline settlement detection device. Background Technique

[0002] A gas pipeline is a pipeline system used to transport combustible gases such as natural gas or liquefied petroleum gas. These pipelines are usually made of materials resistant to corrosion and high pressure to ensure the safe transportation of gas. A gas pipeline system generally includes main pipelines, branch pipelines, valves, compressor stations, pressure regulating stations and other components, and is used to transport natural gas from production sites or storage facilities to consumption locations such as factories, commercial buildings or households. Gas pipelines play a crucial role in modern industry and life, providing a convenient energy source for people. Gas pipelines are usually buried underground or underwater. Affected by factors such as geological movements, soil settlement and underground construction, the gas pipelines will settle. In order to prevent the pipeline from deforming or being unevenly stressed due to settlement, settlement detection of the gas pipeline is carried out to ensure that the settlement distance is within the safe range. At present, when detecting the pipeline settlement, a benchmark is usually fixed on the pipeline, and a scale and other comparison measuring instruments are set on the ground to observe the settlement distance of the pipeline. However, the depths of the buried gas pipelines are different. When detecting, the top of the benchmark is not aligned with the 0 scale of the scale. When detecting, the settlement value needs to be calculated, and there are also easy deviations and errors when reading the value, resulting in inaccurate final measured values, misjudging the safety of the pipeline settlement distance, and affecting the safety of the gas pipeline.

[0019] The scale adjusting mechanism 4 includes a bearing block 41, a screw rod 42, an adjusting plate 43, guide grooves 44 and a scale 45. There are two guide grooves 44, which are opened on both sides of the side surface of the fixed plate 2. The bearing block 41 is fixedly installed on the side surface of the upper end of the fixed plate 2. One end of the screw rod 42 is rotatably connected to the middle of the top of the bottom plate 1, and the other end of the screw rod 42 passes through the screw hole at the bottom middle of the adjusting plate 43 and is rotatably connected to the middle of the bottom of the bearing block 41.

Insert the insertion rods 6 at the four corners of the bottom plate 1 into the ground at the detection position, and insert the lifting rod 32 into the through hole on the bottom plate 1. Push the hand wheel 5 to rotate, so that the hand wheel 5 drives the screw rod 42 to rotate, and the screw rod 42 drives the adjusting plate 43 to move, so that the adjusting plate 43 moves downward along the direction of the guide groove 44, and the bottom of the adjusting plate 43 contacts the top of the lifting rod 32. At this time, the top of the pointer 31 is aligned with the 0 scale at the upper end of the scale 45, and the settlement detection of the pipeline can be carried out. When the gas pipeline settles, the gas pipeline will drive the strap 34, the support plate 33 and the lifting rod 32 to move downward. At this time, the pointer 31 will move downward along the scale for a certain distance. After the detection is completed, directly read the scale value of the pointer 31 on the scale 35, which is the settlement distance of the pipeline.

[0021] It should be noted that the material of the pointer 31 used in the present utility model is rubber. The pointer made of rubber can prevent the pointer from being broken when touched during transportation or installation, and can also endow the pointer with certain toughness, enabling it to bend to a certain extent during installation for easy installation.
