Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0020] refer to Figures 1 to 5 As shown, a photoelectric detection and alarm device for a submarine pipeline in this embodiment includes a housing 1, a detection ring 3 and a detection circuit board 2 disposed in the housing 1, the detection ring 3 is disposed in the external pipeline to be detected, and Coupled with the detection circuit board 2 to send a detection signal to the detection circuit board 2, the detection ring 3 is formed by bending a long rod, and the two ends of the long rod are respectively fixedly connected to the opposite sides of the housing 1, so that The detection ring 3 is rotatably connected with several electrode wheels 4 distributed along the circumference of the detection ring 3. The electrode wheels 4 are all coupled with the detection circuit board 2 and conflict with the inner wall of the pipeline to be...

Abstract

The invention discloses a photoelectric detection alarm device for a submarine pipeline. The device comprises a casing, a detection ring and a detection circuit board arranged in the casing, wherein the detection ring is arranged in the outer to-be-detected pipeline and coupled with the detection circuit board, the detection ring is formed by bending a long rod, two ends of the long rod are fixedly connected with two opposite sides of the casing respectively, a plurality of electrode wheels circumferentially distributed along the detection ring are rotationally connected onto the detection ring, are all coupled with the detection circuit board, abut against the inner wall of the to-be-detected pipeline and transmit a current signal of the inner wall of the into the detection circuit board, and a drive motor and a drive wheel are arranged in the casing. According to the photoelectric detection alarm device for the submarine pipeline, the corrosion condition of the pipeline can be effectively detected by the aid of the casing, the detection circuit board as well as the electrode wheel, and thus, the a series of problems caused by check with naked eyes in the prior art are solved.

Description

technical field [0001] The invention relates to a detection and alarm device, in particular to a photoelectric detection and alarm device for submarine pipelines. Background technique [0002] The pipeline transportation of oil and natural gas has the characteristics of less investment in the transportation process, short transportation cycle, large transportation volume, and high efficiency, making it called "energy blood". It has very obvious advantages in the five major transportation industries and plays an important role in economic development. important role. However, frequent safety accidents caused by damage to submarine pipelines not only destroy the ecological environment, but also cause incalculable losses to the national economy, and also endanger people's lives. Therefore, all walks of life are paying more and more attention to the safety of submarine pipeline operation. [0003] At present, the external corrosion detection of submarine pipelines is mainly ba...
