Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a steam pipeline heat preservation and protection device. Background Art

[0002] Steam pipes have good mechanical properties and thermal insulation properties. Under normal circumstances, they can withstand high temperatures of 120°C. Through modification or combination with other insulation materials, they can withstand high temperatures of 180°C. They are suitable for insulation projects of various cold and hot water high and low temperature pipes.

[0003] After searching, the existing Chinese patent announcement number is: CN 212226433 U, which provides a steam pipe. The patent removes the first insulation layer or the second insulation layer from the pipe body to facilitate the maintenance of the pipe body.

[0004] Although the above patent can inspect and repair the pipeline body, the above steam pipeline still has the following problems: in the above public patent, although it is convenient to inspect and repair the pipeline, after the steam pipeline is installed, it is necessary to connect the entire pipeline to the external steam generating device, and then pass the steam into the interior of the steam pipeline. As the steam is passed for a long time, the steam pipeline will be subjected to the steam heat transfer, thereby causing the steam pipeline to heat up. Although an insulation layer is provided on the outside of the steam pipeline, when the heat insulation layer's heat isolation bearing capacity reaches its limit, the heat will also be dissipated. When the steam is passed into the steam pipeline for a long time, the heat inside the insulation layer will gradually increase, thereby causing the heat to be dissipated, thereby causing the temperature around the steam pipeline to be too high. However, in the above public patent, no protective device is provided. When the staff inspects the steam pipeline, due to work errors or distraction, it is easy for some staff to accidentally touch the steam pipeline, or some non-pipeline maintenance personnel, due to unclear functions of the steam pipeline, accidentally touch the steam pipeline, thereby causing scalding, causing the staff to be injured, thereby affecting the staff's health.

[0005] In view of the above problems, a steam pipeline thermal insulation protection device is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a steam pipeline thermal insulation protection device that can solve the problems of the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steam pipe thermal insulation protection device, comprising a steam pipe body, wherein the steam pipe body is internally rotatably connected with a rotating shaft, a driving assembly is arranged on the surface of the rotating shaft, a gear is fixedly installed on one end of the rotating shaft extending to the outside of the steam pipe body, a fixed block is fixedly installed on the surface of the steam pipe body, a guide rod is threadedly connected to the top of the fixed block, four sliding rings are slidably connected to the surface of the guide rod, protective rings are fixedly installed on the four sliding rings, and the four protective rings are slidably connected on the surface of the steam pipe body.

[0008] Preferably, a rack is fixedly installed between the two middle protective rings, and the rack is meshingly connected with the gear.

[0009] Preferably, the driving assembly is a motor or a combination of a motor and blades.

[0010] Preferably, a tooth removal groove is provided on the surface of the gear.

[0011] Preferably, a return spring is movably sleeved on the surface of the guide rod, the lower end of the return spring is in contact with the fixed block, and the upper end of the return spring is in contact with the sliding ring at the bottom.

When the tooth-disengaging groove 9 coincides with the rack 2, the gear 3 will no longer mesh with the rack 2, and then the protective ring 4 and the rack 2 will be reset by the elastic force of the reset spring 6, and then the protective ring 4 will continue to move up and down, so as to protect the steam pipe body 1 and prevent outsiders from accidentally touching the steam pipe body 1 and causing scalding, thereby improving the protection of outsiders and avoiding injuries.
