Aerogel heat preservation pipe shell

The utility model relates to the technical field of thermal insulation pipe shells, in particular to an aerogel thermal insulation pipe shell. The device comprises a plurality of pipe bodies, the arc surfaces of the pipe bodies are sleeved with aerogel pads, notches in the two sides of each aerogel pad are inclined, the arc surfaces of the pipe bodies are fixedly connected with limiting plates, the limiting plates are inclined by 45 degrees, the arc surfaces of the pipe bodies are fixedly connected with a plurality of spikes, the spikes are of cone structures, and the cone structures are arranged on the arc surfaces of the pipe bodies. Two springs are fixedly connected to the interior of the limiting plate, limiting sharp protrusions are fixedly connected to one ends of the two springs, the two sides of each limiting sharp protrusion are each of a cone structure, and a plurality of threaded grooves are formed in the side wall of the pipe body.
