The utility model relates to the technical field of protective sleeves, in particular to a waterproof and dustproof pipeline through-wall heat preservation protective sleeve which comprises a top plate arranged between a wall and a pipeline, a clamping plate arranged on one side of the top plate and surrounding the pipeline, an extension column arranged at the bottom of the top plate, a shaft sleeve arranged at the bottom of the extension column, a threaded column arranged in the shaft sleeve in a sliding mode and a spring. Under the action of the spring, the clamping plate on one side of the top plate is tightly attached to the pipeline, the center control heat insulation layer is arranged on the other side of the clamping plate, the temperature of the pipeline is kept, and due to the arrangement of the spring, the clamping plate can be tightly attached to the pipeline, gap air leakage is reduced, and the heat preservation effect is improved. And the thermal insulation performance is low. 本实用新型涉及保护套技术领域，尤其涉及
