The splicing tool for the modularized floating fan foundation according to claim 8, wherein truss racks are arranged on the upper end face and the lower end face of the truss, a third driving gear, a third driven gear, a fourth driving gear and a fourth driven gear are further arranged in the truss box, the third driving gear and the third driven gear coaxially rotate, the third driven gear is meshed with the truss racks at the upper end of the truss, the fourth driving gear and the fourth driven gear coaxially rotate, the fourth driven gear is meshed with the truss racks at the lower end of the truss to rotate, and the third driving gear is meshed with the fourth driving gear to drive.

10. A method of constructing a modular floating fan foundation splice fixture according to any one of claims 1-9, comprising the steps of:

s1: the modular fan foundation of the tooling to be spliced is transported to a tooling machine position of a dock through a transport ship;

s2: moving the tool to the lower part of the first transverse support, lifting the tool to be consistent with the horizontal height of the first transverse support by utilizing a lifting assembly, and enabling the transverse support clamping grooves to be clamped at two ends of the first transverse support to be fixed, wherein the first transverse support is positioned at a fixed position by utilizing a transportation plate vehicle;

s3: the distance between the two fixed assemblies is adjusted through the transverse moving assembly, the distance is used as a fixed tool machine position, and the second transverse support to be assembled is placed on a transportation board vehicle of the dock;

s4: starting a first driving motor of the power assembly, driving the turntable to rotate through a multi-stage gear, driving the cable to extend out through the wire assembly, fastening the gripper assembly with the second cross brace, and aligning the two cross braces to be spliced through the cable;

s5: when the cable is recovered, the cable can adjust the alignment of the two cross braces, so that the second cross brace is gradually close to the first cross brace;

s6: after the two transverse struts are attached, the hard fixing between the two fan foundations is completed manually through bolts and bolts;

s7: after the hard fixing is completed, the frame fixing component is detached from the first transverse support and transferred to a fan foundation which is needed to be spliced in addition, and the tooling process is circulated.
