Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas pipeline detection, in particular to a corrosion detection device based on an oil and gas pipeline. Background Technique

[0002] Oil and gas pipelines are pipeline systems used to transport oil and natural gas, usually laid underground. They play an important role in connecting oil fields and refineries, and natural gas production sites and usage sites. Oil and gas pipelines can ensure the transportation and supply of energy and play a crucial role in the energy transportation process. After the production of oil and gas pipelines, corrosion detection devices are required to detect oil and gas pipelines.

[0003] When the existing corrosion detection devices on oil and gas pipelines are in use, corrosion probes are usually used to detect oil and gas pipelines. Since the positions of oil and gas pipelines are usually fixedly installed, after one side of the oil and gas pipeline is detected, the position of the entire oil and gas pipeline needs to be adjusted so that the detection position is facing the corrosion probe. The efficiency of the corrosion detection device for detecting oil and gas pipelines is average. For this reason, we propose a corrosion detection device based on an oil and gas pipeline. Content of the Utility Model

[0004] The purpose of the utility model is to provide a corrosion detection device based on an oil and gas pipeline to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A corrosion detection device based on an oil and gas pipeline includes a bearing plate. A bottom support frame is installed at the bottom of the bearing plate, and a servo motor is connected to the lower surface of the bearing plate. The output end of the servo motor is connected to a rotating shaft. The top end of the rotating shaft penetrates the top wall of the bearing plate, and a circular frame is installed at the top of the rotating shaft. A clamping mechanism is arranged inside the circular frame. A fixed seat is arranged at the right end of the upper surface of the bearing plate. A PLC controller and an audible and visual alarm are connected to the outer side wall of the fixed seat. A lifting component is arranged inside the fixed seat. The lifting component includes a connecting slider. An electric push rod is installed on the outer side wall of the connecting slider, and the telescopic end of the electric push rod is connected to a corrosion probe.

[0007] Further: The clamping mechanism includes four groups of adjusting screws. All four groups of adjusting screws penetrate the side wall of the circular frame, and a clamping plate is arranged at the bottom end of each group of adjusting screws.

[0008] Further: The lifting component further includes a reduction motor. The reduction motor is located at the top of the fixed seat, and the output end of the reduction motor is connected to a lead screw. A threaded sleeve is threadedly connected to the lead screw. The outer side wall of the threaded sleeve is connected to the inner side wall of the connecting slider. A through groove is opened on one side of the fixed seat close to the circular frame, and the through groove is slidably connected to the connecting slider.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model detects the corrosion condition of the oil and gas pipeline through a corrosion probe and feeds back the detected result to the PLC controller in real time. When the oil and gas pipeline shows a corrosion condition, the PLC controller controls the sound and light alarm to work to remind the detection personnel. The rotation of the oil and gas pipeline can be driven by the operation of the servo motor, and the rotation of the lead screw can be driven by the operation of the reduction motor.

The oil and gas pipeline is detected through the corrosion probe. This is the prior art, and the specific working principle will not be elaborated here. Before use, the electrical ends of each electrical device are electrically connected to an external power source and the electrical end of the PLC controller 7. When detecting the oil and gas pipeline, place its bottom inside the circular frame 4, and fix the position of the oil and gas pipeline through the clamping mechanism. The operation of the servo motor 3 can drive the oil and gas pipeline clamped inside the circular frame 4 to rotate. Through the operation of the lifting component, the connecting slider 14 and the electric push rod 9 can be driven to move up and down. The operation of the electric push rod 9 can drive the corrosion probe 10 to stretch, so that the corrosion probe 10 moves up and down and left and right to face the outer wall of the oil and gas pipeline, and different surfaces of the oil and gas pipeline can be detected, realizing the all-round corrosion detection of the oil and gas pipeline and improving the corrosion detection efficiency of the oil and gas pipeline.
