The first type is metal pipes, such as hot-dip cast iron pipes, copper pipes, stainless steel pipes, etc. lined with plastic. The second type is plastic-clad metal pipes, such as steel-plastic composite pipes and aluminum-plastic composite pipes. The third type is plastic pipes, such as PB pipes and PP-R pipes. When some large-diameter water pipes are used, dirt generated by long-term discharge will accumulate on the inner wall of the pipe body. If these dirt are not treated, the volume of dirt accumulation will gradually increase during subsequent use, eventually causing blockage in the water pipe, affecting the overall use effect of the water pipe. Therefore, in order to properly descale the water pipe, water pipe descaling equipment is required.

By moving the first movable arc support plate 902 and the second movable arc support plate 903 on the outer fixing screw 901, as Figure 5 As shown, the first movable arc support plate 902 and the second movable arc support plate 903 can move on the outer fixing screw 901 to support and fix the inner diameters of different water pipes 1.

[0072] An outer frame 12 is installed on the fixed sleeve rod 2, and external nail cones 13 are installed on the front and rear sides of the outer frame 12. After the water pipe 1 is supported by the supporting mechanism 9, it is mounted on the outside of the water pipe 1 through the outer frame 12, and is nailed to the outside of the water pipe 1 through the external nail cones 13 to reinforce and stabilize it.

[0074] In the present invention, a descaling mechanism 5 is used for descaling through a water pipe 1. The descaling mechanism 5 mainly uses a driving motor 518 to make a plurality of segmented scrapers 514 rotate and descale on the inner wall of the water pipe 1. Each segmented scraper 514 can be installed on the extended inner plate 512 at a required height through a mounting rod 515 and a mounting sleeve 516, such as Figure 6As shown, the segmented scraper 514 is spliced ​​and installed on the extended inner plate 512. The segmented scraper 514 and the extended inner plate 512 are both equipped with the mounting holes 513 and through holes 517, and there will be no obstruction when encountering water. The mounting fixture 7 is driven to rotate by the driving motor 518, and the mounting fixture 7 will drive the segmented scraper 514 distributed on both sides of the built-in mounting rod 4 to remove the scale in the pipe, and the segmented scraper 514 and the extended inner plate 512 are both installed on the movable frame 506. The movable frame 506 can adapt to the water pipe 1 with different inner diameters. The movable frame 506 can move horizontally to both sides on the cross brace 502 fixed on the built-in mounting rod 4, and adapt according to the size of the inner diameter of the water pipe 1. After adapting to the water pipe 1, it can be fixed by the mounting screw 510 and reinforced by the fixing nut 511, as shown in FIG. Figure 2 As shown, the two movable racks 506 are combined to display the small inner diameter of the pipe, while the water pipe 1 is displayed with a large inner diameter. When the two movable racks 506 are moved separately, they can gradually adapt to the inner diameter of the large water pipe. Figure 3 As shown, the mobile frame 506 is disassembled for display. Therefore, the water pipe 1 can be descaled quickly during descaling, and can also have an adjustable function, and can be adjusted to suit different water pipe inner diameters for descaling.

[0075] When descaling the water pipe, a rod cavity 1001, multiple high-pressure nozzles 1002, a connecting pipe 1003 and a connecting head 1004 are added to the descaling structure. A pump is connected through the connecting head 1004. The pump is not shown. The pump can be connected to a barrel for placing descaling liquid. The barrel of descaling liquid is not shown. The barrel of descaling liquid is passed through the pump to the connecting pipe 1003 and then stored in the rod cavity 1001. The pump is then removed and then sprayed onto the scale on the inner wall of the water pipe 1 through the multiple high-pressure nozzles 1002 to speed up the removal of the scale.

[0076] When the scale in the water pipe 1 is removed and scraped off, part of it is collected by the installed inverted flat-top cone collecting stereo basket 601.

The first movable arc support plate 902 and the second movable arc support plate 903 can also be adjusted to adapt to the size of the inner wall diameter of the water pipe 1. By moving the first movable arc support plate 902 and the second movable arc support plate 903 on the outer fixing screw 901, as shown in FIG. Figure 5As shown, the first movable arc support plate 902 and the second movable arc support plate 903 can move on the outer fixing screw 901 to support and fix the inner diameters of different water pipes 1.
