[0002] Internal pipeline repair is a technology used to repair damaged or aging pipeline systems. It aims to restore the functionality and integrity of the pipeline while reducing the impact on the surrounding environment during the repair process. This method has the advantages of being efficient, economical and environmentally friendly.

[0003] For existing pipelines that have leakage or damage, for small leaks, sealants, repair tape or leak-proof agents can be used for quick repair. These materials can quickly solidify to form a strong sealing layer. For larger damage, pipe welding or replacement of the damaged section can be used to ensure a long-lasting repair effect.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses an existing pipeline internal repair tool.

[0035] Reference Figure 1 and Figure 2 , an existing pipeline internal repair tool, including a hollow tube 1, a liquid injection tube 2 is fixedly connected to the inside of the hollow tube 1, one end of the hollow tube 1 is hinged with multiple connecting tubes 3, the end of the connecting tube 3 away from the hollow tube 1 is fixedly connected to a pressure plate 4, a plurality of holes 5 are opened on the pressure plate 4, an anti-slip component is installed on the outer wall of the hollow tube 1, one side of the pressure plate 4 is fixedly connected to an electric telescopic rod 11, the top of the electric telescopic rod 11 is installed with a cleaning component, the electric telescopic rod 11 is fixedly connected to a lighting lamp 17, the electric telescopic rod 11 is fixedly connected to a detection probe 18, the detection probe 18 is electrically connected to an external controller, both ends of the pressure plate 4 are fixedly connected to two support plates 19, and a roller 20 is rotatably connected between the two support plates 19.

[0036] When in use, first select the position of the pipe operation hole according to the on-site construction conditions, then send the device into the pipe through the pipe operation hole and push it forward. During the pushing process, the lighting lamp 17 can be turned on to illuminate the inside of the pipe, and then the detection probe 18 can be used to check the damaged position of the pipe. When the detection probe 18 detects the damaged position, the multiple pressure plates 4 are gradually opened by rotating the anti-slip component, so that the multiple pressure plates 4 are fitted with the inner wall of the pipe. The operation of the anti-slip component can make the device adapt to pipes of various sizes, thereby improving the overall practicality of the device. When the multiple pressure plates 4 are opened and fit with the inner wall of the pipe, the cleaning component on one side of the pressure plate 4 will fit with the inner wall of the pipe at the same time. At this time, the tool is pushed back and forth at the damaged part of the pipe to clean the pipe through the cleaning component. The damaged part is cleaned and all the dirt remaining in the damaged part is removed to avoid affecting the subsequent repair of the damaged part. When the inner wall of the pipeline is cleaned, one end of the injection tube 2 can be connected to the external pump body, and the repair liquid can be transmitted to the inside of the pressure plate 4 through the guidance of the injection tube 2 and the connecting tube 3. Then the repair liquid will be squeezed out from the multiple holes 5. At this time, the hollow tube 1 can be pulled to drive the multiple pressure plates 4 to move and can also be continuously rotated during the movement. After pulling the multiple pressure plates 4 and rubbing them against the pipeline, a slight adsorption force will be generated to adhere the repair liquid sprayed from the holes 5 to the inner wall of the pipeline. At this time, through the movement of the pressure plate 4 and the cooperation of the roller 20, the repair liquid can be evenly applied to the damaged part of the pipeline, thereby realizing quick and convenient repair without excavation or dismantling the damaged pipeline, which greatly reduces the repair cost.

[0037] Reference Figure 1 and Figure 3 The anti-slip component includes a hollow tube 2 6 slidably arranged on the outer wall of the hollow tube 1, one end of the hollow tube 2 6 is fixedly connected to a connecting head 7, a threaded groove 8 is provided on the outer wall of the hollow tube 1, and the connecting head 7 is threadedly connected to the threaded groove 8. The end of the hollow tube 2 6 away from the connecting head 7 is evenly fixedly connected to a plurality of hinge seats, and a hinge plate 9 is hinged on the plurality of hinge seats. The interior of the hinge plate 9 is slidably connected to a lifting plate 10, one end of the lifting plate 10 is hinged to the connecting tube 3, and the interior of the hinge plate 9 is fixedly connected to an electric telescopic rod 11, and the output end of the electric telescopic rod 11 is fixedly connected to one end of the lifting plate 10.

[0038] When the cam 7 is in operation, the cam 7 is rotated on the hollow tube 1, and the threaded engagement of the cam 7 and the threaded groove 8 makes the cam 7 drive the hollow tube 2 6 to move on the hollow tube 1. The movement of the hollow tube 2 6 can drive one end of the hinged plate 9 to move along with the hollow tube 2 6, thereby making the hinged plate 9 rotate. At this time, the support and resistance of the other end of the hinged plate 9 can push the multiple connecting tubes 3 to open, thereby driving the multiple pressure plates 4 to gradually open, so that the multiple pressure plates 4 are in contact with the inner wall of the pipe. When the inner wall of the pipe is large and the pressure plates 4 cannot be in contact with the inner wall by the movement of the hollow tube 2 6, the electric telescopic rod 11 can be started to operate to push the lifting plate 10 to be ejected inside the hinged plate 9, thereby pushing the pressure plate 4 to expand outward for a second time until it is in contact with the inner wall of the pipe. Therefore, the device can be adapted to pipes of various sizes, thereby improving the overall practicality of the device.

[0039] Reference Figure 1 、 Figure 4 and Figure 5 The cleaning component includes a fixed plate 12 fixedly connected to the top of the electric telescopic rod 11, a cleaning plate 13 is slidably connected to the inside of the fixed plate 12, a plurality of springs 14 are fixedly connected to the inside of the fixed plate 12, one end of the plurality of springs 14 is fixedly connected to the bottom of the cleaning plate 13, a baffle 15 is symmetrically fixedly connected to the bottom of the cleaning plate 13, the baffle 15 is slidably connected to the fixed plate 12, and a scraper 16 is fixedly connected to the top of the electric telescopic rod 11.

[0040] During use, when multiple pressure plates 4 are stretched out and fit against the inner wall of the pipe, the cleaning plate 13 and the scraper 16 on one side of the pressure plate 4 will fit against the inner wall of the pipe at the same time, and the elasticity of the spring 14 can make the cleaning plate 13 always keep in contact with the inner wall of the pipe. At this time, by pushing the tool back and forth at the damaged part of the pipe, the cleaning plate 13 and the scraper 16 are driven to move together. The scraper 16 can scrape off the dirt at the damaged part, and then the cleaning plate 13 can perform a secondary cleaning on the remaining dirt, so as to clean the damaged part of the pipe in detail and remove all the dirt remaining at the damaged part to avoid affecting the subsequent repair of the damaged part.

[0041] The implementation principle of an existing pipeline internal repair tool in this embodiment is as follows: when in use, first select the position of the pipeline operation hole according to the on-site construction conditions, then send the device into the pipeline through the pipeline operation hole and push it forward. During the pushing process, the lighting lamp 17 can be turned on to illuminate the inside of the pipeline, and then the damaged position of the pipeline can be checked through the detection probe 18. When the detection probe 18 detects the damaged position, the connector 7 is rotated on the hollow pipe 1 by twisting the connector 7. The threaded fit between the connector 7 and the threaded groove 8 will cause the connector 7 to drive the hollow pipe 2 6 to move on the hollow pipe 1, and the movement of the hollow pipe 2 6 can drive the hinged plate One end of 9 moves with the hollow tube 2 6, thereby causing the hinge plate 9 to rotate. At this time, the support and resistance of the other end of the hinge plate 9 can push the multiple connecting tubes 3 to open, thereby driving the multiple pressure plates 4 to gradually open, so that the multiple pressure plates 4 are in contact with the inner wall of the pipe. When the inside of the pipe is large and the pressure plates 4 cannot be brought into contact with the inner wall by the movement of the hollow tube 2 6 alone, the electric telescopic rod 11 can be started to push the lifting plate 10 out of the inside of the hinge plate 9, thereby pushing the pressure plates 4 to expand outward for a second time until they are in contact with the inner wall of the pipe. Therefore, the device can be adapted to pipes of various sizes, thereby improving the overall practicality of the device.

[0042] When the plurality of pressure plates 4 are stretched out and fit to the inner wall of the pipe, the cleaning plate 13 and the scraper 16 on one side of the pressure plate 4 will fit to the inner wall of the pipe at the same time, and the elasticity of the spring 14 can make the cleaning plate 13 always keep in contact with the inner wall of the pipe. At this time, by pushing the tool to move back and forth at the damaged part of the pipe, the cleaning plate 13 and the scraper 16 are driven to move together, and the dirt at the damaged part can be scraped off by the scraper 16, and then the remaining dirt can be cleaned for a second time by the cleaning plate 13, so as to clean the damaged part of the pipe in detail and remove all the dirt remaining at the damaged part to avoid affecting the subsequent repair of the damaged part. When the inner wall of the pipe is cleaned After completion, one end of the injection tube 2 can be connected to the external pump body, and the repair liquid can be transmitted to the inside of the pressure plate 4 through the guidance of the injection tube 2 and the connecting tube 3, and then the repair liquid will be squeezed out from the multiple holes 5. At this time, the hollow tube 1 can be pulled to drive the multiple pressure plates 4 to move and can also be continuously rotated during the movement. By pulling the multiple pressure plates 4 and rubbing them against the pipeline, a slight adsorption force will be generated to adhere the repair liquid sprayed out of the holes 5 to the inner wall of the pipeline. At this time, through the movement of the pressure plate 4 and the cooperation of the roller 20, the repair liquid can be evenly applied to the damaged part of the pipeline, thereby realizing quick and convenient repair without excavation or demolition of damaged pipelines, greatly reducing the repair cost.
