Insulating layer structure with diversion function

The utility model provides an insulating layer structure with a diversion function, which comprises a plurality of insulating blocks fixed on a liquid tank peripheral plate, the insulating blocks are fixed by a fixing device and form a gap with the liquid tank peripheral plate, the innermost side of the gap between two adjacent insulating blocks is covered by a diversion device, and the diversion device covers the insulating blocks. Therefore, a closed circulation layer is formed between the inner surface of the insulation block and the peripheral plate of the liquid tank, when the liquid tank is damaged, leaked gas or liquid enters the circulation layer, the leaked gas can be detected through the gas detection device, and the leaked liquid can be drained into a special leaked liquid collection device through the flow guide device. Compared with the prior art, the utility model has the advantages of excellent thermal insulation performance, long service life, high leakage treatment efficiency and convenience
