[0024] See also Figure 1-4 The surface of the fixed plate 8 is rotatably connected with a rotating block 9, and the rotating block 9 is connected to the positioning rod 6 by a thread. The threaded connection design of the rotating block 9 and the positioning rod 6 makes it easy to fix the inner sleeve 7 inside the outer sleeve 1 through the positioning rod 6. The surface of the fixed plate 8 is rotatably connected with a rotating plate 10, and the rotating plate 10 is connected to the card slot 5 by a thread. The threaded connection design of the rotating plate 10 and the card slot 5 makes it easy to fix the rotating plate 10 in the card slot 5.

[0025] Embodiment 2

[0026] See also Figure 1-4The surface of the outer sleeve 1 is provided with an inner sleeve 12, and the material of the inner sleeve 12 is glass wool. The glass wool material has good thermal insulation and heat insulation properties, thereby preventing the inner sleeve 7 from freezing and cracking. The surface of the inner sleeve 12 is provided with an outer sleeve 13. The design of the outer sleeve 13 and the inner sleeve 12 has the effect of protecting the outer sleeve 1. The material of the outer sleeve 13 is epoxy resin, and the epoxy resin material has good chemical corrosion resistance and wear resistance, thereby improving the corrosion resistance of the outer sleeve 1.

[0027] Working principle: When the inner sleeve 7 needs to be disassembled and replaced, the rotating block 9 is rotated first. After the rotating block 9 is rotated away from the positioning rod 6, the rotating plate 10 is rotated by the shifting block 11. After the rotating plate 10 is rotated out of the card slot 5, the inner sleeve 7 can be pulled out of the outer sleeve 1, and then the new inner sleeve 7 is inserted into the outer sleeve 1.

After the rotating plate 10 is connected, the rotating block 9 is connected to the positioning rod 6 through a thread. The outer sleeve 1, the inner sleeve 7, the outer wing plate 3, the card slot 5, the positioning rod 6, the fixing plate 8 ... The fixed plate 8, the rotating block 9, the rotating plate 10 and the card slot 5 facilitate the disassembly, assembly and replacement of the inner sleeve 7, thereby avoiding the need to dismantle the pipeline when maintaining and replacing the pipeline. When using the pipeline waterproofing device, the inner sleeve 12 will have the effect of insulating the outer sleeve 13, and the outer sleeve 13 will have the effect of anti-corrosion of the outer sleeve 13. The outer sleeve 13 and the inner sleeve 12 prevent the inner sleeve 7 from freezing and cracking, improve the thermal insulation of the outer sleeve 1, and also improve the anti-corrosion performance of the outer sleeve 1, thereby ensuring the service life of the outer sleeve 1 and the inner sleeve 7.
