[0002] The water supply pipe is one of the main water supply equipment, especially the water supply pipe on the municipal ground. Most of the water supply pipes are made of iron material. Since the water supply line has a certain length, the water supply pipe is connected with several iron pipes to form a water supply line. At the same time, the iron pipes used in the water supply line can be easily disassembled and maintained. Among them, the long-term water supply of the water supply pipe will cause corrosion of the inner wall. The corroded rust blocks on the inner wall need to be cleaned, so a rust removal device is needed.

[0054] The adjusting mechanism is used to drive the two scrapers 5 to move.

[0055] In this embodiment, Figure 1 , 2 As shown in Figure 4, first, the cleaning water pipe 4 is inserted into the connected scraper 5 from the top of the water pipe I to be derusted, so that the scraper 5 can be inserted into the bottom of the water pipe I, and then the water pipe I is vertically placed on the support seat 2 for fixation. At the same time, the other end of the cleaning water pipe 4 is passed through the fixed pipe 121 for fixation, wherein the clamping plate 3 arranged inside the support seat 2 clamps and fixes the inserted water pipe I, and at the same time, the other end of the water pipe I can be inserted into the limiting frame 7 for limiting.

[0056] Then, the driving mechanism drives the L-shaped lifting rod 12 to rise, and the L-shaped lifting rod 12 drives the connected cleaning water pipe 4 to rise, and the cleaning water pipe 4 can drive the connected scraper 5 to rise.

A rotating column 33 is movably connected to the outer surface of the clamping rod 31, and one end of the clamping rod 31 is connected to a first movable block 32, and the first movable block 32 is threadedly connected to the inside of the rotating column 33. One end of the rotating column 33 passes through the support seat 2 and is fixedly connected to the fourth gear 34. The top of the fastening ring 22 is meshed with the fourth gear 34 through a set gear ring. One end of the top of the support seat 2 is movably inserted and connected with the insertion rod 24, and the positioning groove 221 opened at the top of the fastening ring 22 is embedded and matched with the insertion rod 24, and the other end of the insertion rod 24 is fixedly connected to the third spring 241.

[0063] In this embodiment, Figure 2 and 3 As shown, by manually rotating the fastening ring 22, the connected clamping plate 3 can be driven to clamp and fix the water pipe 1 inserted into the support seat 2. That is, when rotating the fastening ring 22, first pull the insertion rod 24 out of the positioning groove 221. At this time, rotating the fastening ring 22 can drive the fourth gear 34 engaged and connected to rotate through the gear ring. Since the fourth gear 34 is fixed to one end of the rotating column 33, the other end of the rotating column 33 penetrates and rotates on the support seat 2, so that the rotating column 33 can be driven to rotate by rotating the fastening ring 22. Since the clamping rod 31 connected to one side of the clamping plate 3 is movable The first movable block 32 connected to the clamping rod 31 is connected to the inside of the rotating column 33 and can be threadedly matched with the rotating column 33. At the same time, the limiting rod 35 connected to one side of the clamping plate 3 penetrates and slides with the support seat 2, so that when the rotating column 33 rotates, it can drive the first movable block 32 with threaded matching to move. The first movable block 32 drives the clamping plate 3 to move through the clamping rod 31.

The four bevel gears 832 are meshed and connected with the first bevel gear 841, and the first bevel gear 841 is fixed on the screw rod 84, and the screw rod 84 rotates on the base 1 and the L-shaped vertical plate 11, so that the second bevel gear 81 can drive the screw rod 84 to rotate. Since the screw rod 84 is threadedly matched with the slide 122, and the slide 122 slides on the L-shaped vertical plate 11, and one end of the L-shaped lifting rod 12 is connected to the slide 122, the rotating screw rod 84 pushes the L-shaped lifting rod 12 connected to the slide 122 to rise and fall, and one end of the cleaning water pipe 4 is fixed on the fixed pipe 121 connected to the L-shaped lifting rod 12, so that the cleaning water pipe 4 can be driven to rise and fall, and then the driving mechanism can synchronously drive the water supply pipe I to rotate and the cleaning water pipe 4 to rise and fall.

Since the second gear 63 and the adjusting arms 62 on both sides are meshed and connected with each other through racks, the two adjusting arms 62 slide on the two first sliding rods 61 respectively, and since one end of the adjusting arm 62 movably extends out of the adjustment box 6 is connected with the movable column 54 through a fixed movable plate 621, and the movable column 54 is movably connected to the return frame 42, when the second gear 63 drives the two adjusting arms 62 to displace, the adjusting arm 62 can drive the connected movable column 54 to displace on the return frame 42, and the movable column 54 can drive the connected scraper 5 to displace, thereby being able to adjust the spacing between the two scrapers 5, so as to be suitable for scraping rust blocks on water pipes I with various different diameters.

[0077] Example 5

[0078] The positioning mechanism includes a limit frame 7, which is rotatably connected to a second roller 72 inside the limit frame 7. Two symmetrical first rollers 71 are arranged inside the limit frame 7. The first roller 71 is rotatably connected to a rotating arm 711 through a bearing, and one end of the rotating arm 711 rotates on the limit frame 7.

[0080] The overall working principle of the present invention is as follows:

[0081] like Figure 1 and 2As shown, the water pipe I to be derusted is first placed vertically on the top of the support seat 2. The support seat 2 clamps and fixes one end of the inserted water pipe I through the provided clamping plate 3. At the same time, the other end of the water pipe I can be inserted into the limiting frame 7 for positioning.

[0082] Then, if Figure 7 , 8 As shown in Figures 9, turning on the motor 8 can drive the support seat 2 to rotate on the base 1, thereby driving the clamped water pipe 1 to rotate. At the same time, the motor 8 can drive the cleaning water pipe 4 to rise, and the cleaning water pipe 4 can drive the scraper 5 connected at one end to rise, so that the scraper 5 can rise inside the water pipe 1. At the same time, the rotating support seat 2 can enable the scraper 5 to scrape the inner wall of the water pipe 1, and can scrape off the rust on the inner wall of the water pipe 1.

[0083] Among them, the other end of the cleaning water pipe 4 can be connected to the rust removal liquid input pipe, so that the rust removal liquid can be input into the cleaning water pipe 4. The cleaning water pipe 4 can spray the rust removal liquid on the inner wall of the water pipe I through the connected nozzle 41, so that the rust blocks on the inner wall of the water pipe I can fall off more easily.

[0084] Finally, if Figure 2 As shown, the scraped rust blocks and rust removal liquid can fall into the support base 2, and the conical filter cover 212 arranged inside the support base 2 can filter the rust removal liquid. The support base 2 can collect the rust blocks in a centralized manner, and the filtered rust removal liquid can be discharged and collected through the drain pipe 211 on the fixed cover 21, so as to facilitate the recycling of the rust removal liquid.

[0085] In summary, the inner wall of the water pipe 1 can be automatically scraped and rusted, which can improve the rust removal effect and efficiency.
