Foundation pit diagonal bracing steel pipe deformation on-line detection device

The invention relates to the technical field of foundation pit inclined strut detection, in particular to a foundation pit inclined strut steel pipe deformation online detection device which comprises an inclinometer pipe arranged on an inclined strut steel pipe and inserted into a foundation pit along with the inclined strut steel pipe, and a deformation detection mechanism device placed in the inclinometer pipe and capable of moving in the length direction of the inclinometer pipe. According to the device, the inclinometer pipe extending in the length direction of the inclined strut steel pipe is arranged on the inclined strut steel pipe, when the inclined strut steel pipe is bent, the inclinometer pipe connected with the inclined strut steel pipe is also bent, the deformation detection mechanism device is placed in the inclinometer pipe and moves at equal intervals, the bending degree of the inclinometer pipe is detected, and then the bending degree of the inclined strut steel pipe is reflected; the accura
