Wherein the fixed mounting seat includes elasticity holder, locating part and base 11, and the cross-section of base 11 is square, and the axis of elasticity holder use base 11 is the symmetry axis, and the symmetry sets up in the inboard of base 11 to at the inside centre gripping space to pulse eddy current sensor that forms of base 11. The limiting part is arranged on the outer side of the base 11 corresponding to the elastic clamping part so that the elastic clamping part can slide along the direction towards/away from the pulse eddy current sensor, and one end of the flexible connecting part is connected with the base 11.
The utility model provides a fixing device for metal pipeline corrosion monitoring's pulse eddy current sensor, just can monitor metal pipeline's wall thickness under the condition of the heat preservation of not tearing metal pipeline open through setting up pulse eddy current sensor, be convenient for pulse eddy current sensor at the installation of metal pipeline lateral wall and dismantlement through setting up fixed mounting seat and flexonics spare, thereby install the wall thickness attenuate data that pulse eddy current sensor can real-time supervision metal pipeline corrode and lead to on metal pipeline's lateral wall through fixing device, thereby avoided leaking the inspection that causes because of periodic detection, the higher defect of human cost, the security that metal pipeline used has been improved.
Specifically, the base 11 is a rectangular parallelepiped provided with a containing cavity, and one end of the base 11 is open. Wherein, the symmetry is provided with the elasticity holder on the inside lateral wall all around of base 11, and wherein, the elasticity holder of relative setting can be dismantled with pulse eddy current sensor both ends respectively and be connected, and the relative elasticity holder that sets up can adjust the distance of the relative elasticity holder that sets up in order to adapt to not equidimension pulse eddy current sensor finally with the stable centre gripping of pulse eddy current sensor in base 11 with pulse eddy current sensor's inside at base 11 through adjusting the locating part.
