As shown in fig. 5, the present invention provides a health detection method for large submarine pipeline, which comprises the following steps:
will the utility model discloses submarine pipeline overhauls the entry is arranged in to equipment, and under preceding, back wall-supporting device supported, the device will hover in the pipeline. The stepping motor is started to drive the spherical roller to roll along the pipe wall, and the whole device of the utility model moves forwards; in the moving process, the cleaning device is started to clean the pipe wall in advance, the scanning platform is started, the platform rotates around the central axis of the equipment at a constant speed, and the magnetic probe and the non-magnetic material on the platform extend out of the detection platform under the drive of the stepping motor to start scanning. The scanning modes of the probe can be divided into two categories according to whether the scanning probe has magnetism:
(1) mechanical scanning mode of non-magnetic probe: when the non-magnetic probe reaches the inner wall of the scanned pipeline 32, the pressure between the non-magnetic scanning probe and the wall of the scanned pipeline is set to be a constant value, the scanning platform is rotated to scan the pipeline wall, and the dot matrix on the pipeline wall is a scanning path. When the probe encounters a corrosion site 33, a crack 34 (or adsorbate) on the inner wall of the tract, the pressure felt by the pressure sensor will become less (or more) greater. At this moment, the second walking motor can drive the probe to further extend forwards (or retract), the pressure that the probe head was experienced is ensured to be invariable, and at this moment, the position recording device can record the length that the probe stretches out the platform to control chip in with data input. Thereby counter-diffracting the two-dimensional topography 35 of the inner wall of the pipe.
(2) Magnetic scanning mode of magnetic probe: when the magnetic probe reaches the inner wall of the scanned pipe, if the pipe wall 32 is made of ferromagnetic metal such as steel, it will generate attraction force to the probe head. The magnetic probe is close to the pipe wall but not contacted with the pipe wall, the position of the probe relative to the scanning platform is fixed, and the scanning platform is rotated to scan the pipe wall. As shown in fig. 5, when the magnetic probe encounters a corrosion site 33, crack 34 (or adsorbate) on the inner wall of the pipe, the magnetic attraction felt by the probe will become smaller (or larger) due to the change in the pipe corrosion site, crack or magnetic properties. The magnitude of the magnetic attraction force sensed by the needle head is recorded through the pressure sensor, and data are transmitted to the central control chip. Therefore, the two-dimensional magnetic morphology of the inner wall of the steel pipe is inverted, and a picture similar to the two-dimensional morphology of the inner wall of the steel pipe can be obtained. The health condition of the interior of the pipeline can be clearly judged by combining the two.
