Modular suspension bridge main cable fireproof device

The invention provides a modularized suspension bridge main cable fireproof device, and belongs to the technical field of suspension bridge fire prevention. Comprising a body assembly, clamping rings are arranged on the front side and the rear side of the outer end of the body assembly, spraying assemblies are arranged at the front ends of the clamping rings, storage assemblies are arranged above the outer ends of the clamping rings, connecting assemblies are arranged on the outer sides of the rear ends of the clamping rings, and induction alarms are arranged below the outer ends of the clamping rings. The lower shell and the upper shell are clamped and fixed to a main cable, then the spraying assembly and the storage assembly are installed on the outer side and are reinforced through the clamping rings, and then the two adjacent body assemblies can be spliced through the clamping rings to form a whole, continuous wrapping is conducted, and a modular fireproof structure can also be formed; compared with a tra
