Mounting tool and mounting method for C-shaped liquid tank surface sensor cable

The invention provides a mounting tool and a mounting method for a sensor cable on the surface of a C-shaped liquid tank, and the mounting tool comprises an embedded part and a cable supporting part. The embedded part comprises a first end part fixed in the isolation heat preservation layer, a second end part extending out of the isolation heat preservation layer and a connecting section for connecting the first end part and the second end part; the cable supporting part is detachably connected with the second end part, the embedded part is directly fixed on the isolation heat preservation layer through the first end part, and the first end part and the structural surface of the C-shaped liquid tank are still provided with a heat preservation layer with a certain temperature difference, so that the requirement of low temperature resistance is met; fixation of the embedded part and the isolation heat preservation layer can be directly reinforced through other modes such as screws and screw holes, and the embed
