Embodiment 1

[0033] Such as Figure 1-3 As shown, a "millipede" bionic crawling equipment for leak detection of deep-buried oil pipelines in desert areas, including:

[0034] At least three interconnected worm bodies are composed of two sets of reverse mechanical crawling legs, and the mechanical crawling legs are fixedly connected by two leg connecting rods 17 to form a mechanical foot 9;

[0035] The audio sensor 2 is installed above the worm body and is used for detecting the oil pipeline;

[0036] Detector 1 is installed above the worm body and is used to detect the oil pipeline;

[0037] The power supply battery 4 is installed above the worm body and is used for power supply of crawling equipment components;

[0038] The tracking module 5 is installed at the front of the worm body, and is used to detect the oil pipeline buried deep underground to provide the basis for the correct driving direction of the desert vehicle;

[0039]The data processing center 3 is installed above the in...

Embodiment 2

[0048] The method for leak detection of deep-buried oil pipelines in desert areas comprises the following steps:

[0049] 1) Use the audio sensor 1 to detect along the oil pipeline, select 2 measuring points along the pipeline, and measure the audio signal information of these 2 measuring points;

[0050] 2) Utilize detector 1 to calculate the position of leakage according to the power intensity of 2 frequency components in the audio frequency spectrum of 2 measurement points;

[0051] 3) Send the leakage information to the data processing center 3 for processing. The processed information includes: location information, leakage information, ground path and pipeline information, and then send the information back to the ground pipeline inspection station.

[0052] The conventional technologies in the above embodiments are known to those skilled in the art, and will not be described in detail here.

Embodiment 3

[0053] Embodiment 3: A "millipede" bionic crawling device of the present invention used for leak detection of deep-buried oil pipelines in desert areas is actually used: the tracking module 5 detects deeply buried oil pipelines to provide driving routes for desert vehicles, Ensure that the desert vehicle always drives along the top of the deep-buried oil pipeline. During the driving process, the detector 1 cooperates with the audio sensor 2 to complete the work of detecting the leakage of the oil pipeline. The detector 1 receives the audio signal from the audio sensor 2 and other information , and calculate the location of the leak according to these audio signals, and then the detector 1 transmits a large amount of data information to the data processing center 3 through wireless transmission, and the data processing center 3 processes and analyzes the received large amount of uncalculated data, and deletes useless information, and send valuable oil pipeline leakage informatio...

Abstract

The invention discloses a millipede bionic crawling equipment for detecting leakage of a deep-buried oil conveying pipeline in a desert area. The millipede bionic crawling equipment comprises at leastthree sections of mutually-connected millipede bodies, an audio sensor, a detector, a power supply battery, a tracking module and a data processing center; each millipede body is composed of two reversed mechanical crawling legs, and every two corresponding reversed mechanical crawling legs are fixedly connected through two leg connecting rods to form a mechanical foot; the audio sensor is used for detecting the oil conveying pipeline; the detector is used for detecting the oil conveying pipeline; the power supply battery is used for supplying power to crawling equipment parts; the tracking module is arranged at the front portion of the millipede bodies, and is used for detecting the oil conveying pipeline which is deeply buried underground so as to provide the basis of correct driving direction for a desert vehicle; and the data processing center is used for receiving the data information from the detector, processing and analyzing the received large amount of information which is not calculated and processed and transmitting the information back to a ground pipeline detection station. The invention further provides a method for detecting leakage of the deep-buried oil conveyingpipeline in the desert area. According to the equipment and the method, the problem of leakage detection of the deep-buried oil conveying pipeline in the desert depopulated area is solved, and automatic detection and data remote real-time transmission of the unmanned leakage detection equipment are realized.

Description

technical field [0001] The invention belongs to the technical field of pipeline leakage detection, and in particular relates to a "millipede" bionic crawling device for leak detection of deep-buried oil pipelines in desert areas and a method for leak detection of deep-buried oil pipelines in desert areas. Background technique [0002] The mining and transportation of fossil energy has always plagued the development of countries all over the world, and the importance of pipeline leak detection technology is self-evident. The buried depth of my country's oil and gas pipelines is about 2m underground, and the strength of pipelines gradually enters a dangerous period with the passage of time. Therefore, it is particularly important to strengthen the development and research of leak detection technology. [0003] The oil and gas pipeline leak detection method has developed from the simplest manual inspection along the pipeline section to a more complex method combining computer s...
