Description

Technical Field

[0001] This utility model relates to the field of water pipe repair technology, and in particular to a repair device for damaged water supply pipes. Background Technology

[0002] Water supply pipes are pipes used to transport tap water. Modern water pipes are installed by embedding them in walls. There are three types of water pipes: the first type is metal pipes, such as hot-dip galvanized cast iron pipes with internal plastic lining, copper pipes, stainless steel pipes, etc.; the second type is plastic-coated metal pipes, such as steel-plastic composite pipes, aluminum-plastic composite pipes, etc.; the third type is plastic pipes, such as PB pipes, PP-R pipes, etc.

[0003] By comparing a repair structure for rapid emergency repair of water supply pipes with patent publication number CN221723709U, this solution uses a sealing sleeve and a gasket to directly seal the damaged part of the water supply pipe, preventing leakage. The heating unit and heating wire work together to quickly heat the heat-fusion pipe, achieving rapid repair. However, during heat-fusion repair of the water supply pipe, a large amount of impurities, even mud and sand, may accumulate on the surface, along with residual moisture. If these impurities are not cleaned, they will remain at the repair site, potentially causing gaps and leaks. This reduces the fit between the heat-fusion pipe and the water supply pipe, lowering the quality of the heat fusion. Utility Model Content

[0004] The purpose of this invention is to provide a repair device for damaged water supply pipes in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0027] In this embodiment: the repair mechanism includes fastening arc plates 201 disposed on the upper and lower sides of the pipe body 100. Multiple bolts 218 are installed at both ends of the two fastening arc plates 201, and nuts 219 are provided at the bottom of the bolts 218. A heat fusion chamber 207 is fixed to the end of the fastening arc plate 201 away from the pipe body 100. Multiple heating rods 208 are provided inside the heat fusion chamber 207. A protective net 209 is fixed to the end of the heat fusion chamber 207 near the pipe body 100. Multiple heating rods 208 are provided inside the heat fusion chamber 207. A protective net 209 is fixed to the end of the heat fusion chamber 207 near the pipe body 100. Multiple heating rods 208 are provided on both the front and rear sides of the heat fusion chamber 207. There is a second fixed frame 215, and a partition 216 is slidably installed inside the second fixed frame 215. A hot melt adhesive sheet 217 is installed between the bottom ends of the front and rear partitions 216. The hot melt adhesive sheet 217 is detachable. A tension spring is connected between the partition 216 and the second fixed frame 215. A pressing structure for pressing the hot melt adhesive sheet 217 downward is provided above the hot melt adhesive sheet 217. A cleaning structure for cleaning the surface of the tube body 100 is provided between the tube body 100 and the fastening arc plate 201.

[0028] The cleaning structure includes two sets of first connecting plates 202 disposed on the inner wall of the rear side of the fastening arc plate 201, with two plates in each set. The two first connecting plates 202 in each set are symmetrically arranged in the front-back direction. A dust-adhesive roller 203 is rotatably installed between the two first connecting plates 202 in each set. Two sets of second connecting plates 204 are disposed on the inner wall of the front side of the fastening arc plate 201, with two plates in each set. The two second connecting plates 204 in each set are symmetrically arranged in the front-back direction. A cleaning roller 205 is rotatably installed between the two second connecting plates 204 in each set. The surface of the cleaning roller 205 is frosted. Multiple balls 206 are mounted around the ends of the cleaning roller 205 and the dust-adhesive roller 203.

[0029] The pressing structure includes a first fixed frame 210 disposed between the second fixed frame 215 and the hot melt chamber 207. The first fixed frame 210 is slidably connected to the fastening arc plate 201. A lower pressure plate 211 is slidably installed inside the first fixed frame 210. A pressing plate 213 is fixedly connected between the upper ends of the two lower pressure plates 211. A cutter 212 is fixedly attached to one end of the lower pressure plate 211 near the tube body 100. A compression spring is connected between the lower pressure plate 211 and the first fixed frame 210. A pressure plate 213 is installed between the bottom ends of the two first fixed frames 210. 14. The pressure plate 214 is elastic and detachable. Pressing the two fastening arc plates 201 causes multiple sets of cleaning structures to adhere to the surface of the pipe body 100. Rotating the two fastening arc plates 201 causes multiple sets of cleaning structures to rotate on the surface of the pipe body 100, thereby cleaning the impurities accumulated on the surface of the pipe body 100 in an all-round way, ensuring the cleanliness of the surface of the pipe body 100, so as to ensure that the pipe body 100 and the hot melt adhesive sheet 217 are tightly adhered during the subsequent hot melt repair of the pipe body 100, improving the sealing between the two and enhancing the hot melt quality.

[0030] Working principle: First, press the two fastening arc plates 201 close to the surface of the tube body 100, so that the two sets of cleaning rollers 205 and dust-adhesive rollers 203 on the inner wall of the fastening arc plates 201 are in contact with the surface of the tube body 100. Then, tighten multiple bolts 218 and nuts 219 to fix the position of the two fastening arc plates 201 together. Then, rotate the two fastening arc plates 201 to drive the multiple sets of cleaning rollers 205 and dust-adhesive rollers 203 to rotate. The cleaning rollers 205 are used to polish the surface of the tube body 100, so that impurities are separated from the tube body 100. Then, the dust-adhesive rollers 203 are used to adhere the polished impurities, thereby cleaning the impurities and other small particles on the surface of the tube body 100 in an all-round way, ensuring the cleanliness of the surface of the tube body 100. This ensures that the tube body 100 and the hot-melt adhesive sheet 217 are tightly attached during the later hot-melt repair of the tube body 100, improving the sealing between the two and enhancing the hot-melt quality.

[0031] Then, multiple heating rods 208 inside the heat fusion chamber 207 are activated. The heat generated by the heating rods 208 heats and softens the repaired area of ​​the tube body 100. Then, the heat fusion adhesive sheet 217 is inserted between the bottom ends of the two partitions 216 through the slot at the bottom end of the partition 216. The heat fusion adhesive sheet 217 is then heated and softened by the multiple heating rods 208. Finally, the pressure plate 214 is inserted into the two first fixed frames 210 through the insertion hole at the bottom end of the first fixed frame 210 using the insertion rod at the end of the pressure plate 214. Between the bottom ends of frame 210, apply glue to the end of hot melt adhesive sheet 217 near tube body 100, then press the pressing plate 213 to drive the lower pressing plate 211 to move closer to the surface of tube body 100. When the lower pressing plate 211 moves, it drives the pressure plate 214 at the lower end of the first fixed frame 210 to move. The pressure plate 214 applies pressure to the hot melt adhesive sheet 217, driving the hot melt adhesive sheet 217 to move towards the surface of tube body 100, so that the hot melt adhesive sheet 217 and the surface of tube body 100 are tightly attached and firmly bonded together.

[0032] When the bottom end of the first fixing frame 210 abuts against the surface of the tube body 100, the first fixing frame 210 stops moving, causing the lower pressure plate 211 inside the first fixing frame 210 to continue moving, driving the cutter 212 to continue moving. As the cutter 212 continues to move, it will cut off the front and rear ends of the hot melt adhesive sheet 217. Finally, after the surface of the tube body 100 and the hot melt adhesive sheet 217 have cooled for a period of time, they will solidify firmly together, thus completing the repair work on the surface of the tube body 100.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
