Monitoring and early warning device for high consequence area of oil and gas pipeline

Abstract

The invention discloses a monitoring and early warning device for a high consequence area of an oil and gas pipeline. The device comprises an inverted-U-shaped or inverted-V-shaped main frame buckledon the outer wall of the upper half portion of the oil and gas pipeline; a moving mechanism, a stabilizing mechanism, a stabilizing auxiliary mechanism and a monitoring mechanism are arranged on the main frame, the moving mechanism comprises a driving unit and a moving part, and the driving unit drives the moving part to move on the outer wall of the oil-gas pipeline through a transmission mechanism; the stabilizing mechanism comprises at least two counterbalance weights, and two arms of the main frame are each provided with one counterbalance weight so that the gravity center of the main frame can fall on the center line; the stabilizing auxiliary mechanism comprises a friction attaching piece, and the friction attaching piece is used for providing circumferential friction with the outerwall; and the monitoring mechanism is used for monitoring the oil-gas pipeline. According to the monitoring and early warning device for the high-consequence area of the oil and gas pipeline, the mainframe can be stably arranged on the oil and gas pipeline, meanwhile, the friction force is increased through the stabilizing auxiliary mechanism, the deviation probability of the main frame is reduced, and a supporting device can be passed.

Description

technical field [0001] The invention relates to oil and gas technology, in particular to a monitoring and early warning device for high consequence areas of oil and gas pipelines. Background technique [0002] Oil and gas pipelines need to monitor certain operating data on a regular basis or even in real time. The monitoring equipment commonly used in the prior art includes monitoring robots. The monitoring robot moves forward inside the oil and gas pipeline. The monitoring robot is equipped with corresponding monitoring sensor devices to achieve corresponding monitoring. [0003] For example, the application publication number is CN109357104A, and the invention patent application titled "A Pipeline Inspection Robot" includes a self-propelled oil and gas pipeline tractor to maintain a motion posture device, a power supply control system functional cabin, and three different parts of the power supply control system functional cabin. A group of self-propelled oil and gas pipel...

AI Technical Summary

Problems solved by technology

[0004] Obviously, the monitoring robot running inside the oil and gas pipeline has disadvantages visible to the naked eye, such as entering and moving out of the oil and gas pipeline requires corresponding structures and more steps, and the internal operating environment of the oil and gas pipeline is complex, especially the inside of the oil and gas pipeline, as well as the oil and gas pipeline. The limited internal space restricts the layout of monitoring equipment, etc.

Ideally, it is more reasonable to set up a robot running outside the oil and gas pipeline, but on the one hand, if figure 1 As shown, the oil and gas pipelines are provided with support devices at intervals. How the robot passes through the support devices is a relatively large technical difficulty. The cylinder structure can cover the oil and gas pipeline, but based on the blocking of the above-mentioned support device, the cylinder structure cannot pass through the support device

The above two problems make the robot on the outside of the pipeline more difficult and rarely used
