The inner wall of the main water pipe 1 is slidably connected to a scraper 7, the outer wall of the scraper 7 is fixedly equipped with a water filter plate 8, the outer wall of the scraper 7 is fixedly equipped with a limit strip 20, the outer wall of the scraper 7 is also provided with a roller 13, and the outer wall of the limit strip 20 is opened with a through hole 17, the outer wall of the auxiliary water pipe 2 is rotatably connected to a driven wheel 6, the middle part of the driven wheel 6 is rollingly connected to a transmission belt 10, and the outer wall of the auxiliary water pipe 2 is fixedly equipped with a powerful motor 11.

[0027] In the above structure, by setting the main water pipe 1, the auxiliary water pipe 2, the connecting pipe 5, the scraper 7, and the water filter plate 8 structure, when the user assembles the drain pipe, the connecting pipe 5 and the auxiliary water pipe 2 can be initially fixed to the main water pipe 1 through the threaded connection between the connecting pipe 5 and the docking groove 12, and then the connecting pipe 5 cannot be rotated through the threaded connection between the connecting bolt 22 and the threaded hole 14. After installation, the main water pipe 1 and the auxiliary water pipe 2 are fully fixed to ensure the drainage pipe's diversion and sealing effect on the water body. In the diversion process, the scraper 7 is moved toward the water body by utilizing the mobility of the scraper 7, and the impact force of the water body is offset by the elasticity of the buffer spring 9, thereby reducing The water hammer effect exerts an impact force on the main water pipe 1, the secondary water pipe 2 and the connecting pipe 5. When conveying water, the water will squeeze the water filter plate 8 and the scraper 7 to compress the buffer spring 9, so that the scraper 7 slides along the inner wall of the secondary water pipe 2. At this time, the scraper 7 will scrape the inner wall of the secondary water pipe 2, thereby achieving the effect of automatically cleaning the adhered impurities. After conveying the water, the user can reset the scraper 7 by using the output shaft of the powerful motor 11 to drive the buffer spring 9 and the screw rod 18 to rotate, so that the through hole 17 is threadedly connected to the outer edge of the screw rod 18, thereby driving the scraper 7 to scrape along the inner wall of the main water pipe 1, which can not only reduce the influence of the water hammer effect on the pipe body, but also achieve the effect of automatic cleaning.

[0028] In a preferred embodiment: the outer wall threaded hole 14 of the connecting bolt 22 is threadedly connected to the inner wall of the main water pipe 1, and the secondary water pipe 2 is fixedly connected to the inner wall of the main water pipe 1 through the cooperation of the connecting pipe 5, the slider 21, the threaded hole 14 and the connecting bolt 22. The shape and diameter of the slider 21 are adapted to the shape and diameter of the square groove 15. There are four sliders 21, and the four sliders 21 are evenly distributed along the outer wall of the connecting pipe 5.

[0029] In the above structure, by setting the limit strip 20 and the square groove 15 structure, the drain pipe utilizes the movable characteristics of the scraper 7 and the water filter plate 8 to make the impact force of the water body on the pipe body be offset by the buffer spring 9, thereby achieving the effect of reducing the influence of the water hammer effect on the pipe body, making it have a protective function, and at the same time, the scraper 7 can be moved by the impact force to clean the inner wall of the auxiliary water pipe 2, avoiding excessive adhesives and causing the inner wall of the auxiliary water pipe 2 to be eroded, thereby extending the service life of the drain pipe.

[0030] In a preferred embodiment: one end of the buffer spring 9 close to the water filter plate 8 overlaps the outer wall of the limit strip 20, and the diameter of the through hole 17 is 2 cm smaller than the diameter of the buffer spring 9, a movable groove is opened on the inner wall of the long groove 3, and the outer wall of the limit strip 20 is slidably connected to the inner wall of the movable groove.

[0031] In the above structure, the movable groove and the limit strip 20 structure are provided, so that the limit strip 20 is limited during the movement process, so that the scraper 7 can move stably. At the same time, the limit strip 20 is limited by the roller 13 to ensure that the inner wall of the through hole 17 cannot contact the cross bar 19 after the limit strip 20 is separated from the screw rod 18, thereby improving the stability of the scraper 7 and the through hole 17, avoiding wear of the accessories, and thus extending the service life of the scraper 7 and the through hole 17.

[0032] In a preferred embodiment, the number of scrapers 7 is four, both ends of the four scrapers 7 are fixedly equipped with limit plates, and the outer wall of the limit plate is rotatably connected to the outer wall of the roller 13, and the outer wall of the roller 13 is rollingly connected to the inner wall of the long groove 3.

[0033] In the above structure, by setting up four scraper 7 structures, the inner walls of the main water pipe 1, the auxiliary water pipe 2 and the connecting pipe 5 can be scraped to achieve the effect of automatic cleaning, and the thrust generated by the impact force of the water flow is used to improve the energy utilization rate of the drain pipe, thereby improving the practicality of the drain pipe.

[0034] In a preferred embodiment: one end of the main water pipe 1 provided with the docking plate 4 is the water inlet, and when the main water pipe 1 is filled with water, the buffer spring 9 will be compressed to the limit state.

[0035] In the above structure, the compression of the buffer spring 9 is used to enable the scraper 7 and the water filter plate 8 to scrape off the impurities adhered to the inner wall of the auxiliary water pipe 2 and push them to the water outlet of the auxiliary water pipe 2, thereby facilitating the user to clean the impurities and thereby improving the user's maintenance efficiency of the drain pipe.

[0036] In a preferred embodiment: the output shaft of the powerful motor 11 is fixedly sleeved with a driving wheel, and the middle part of the driving wheel is rollingly connected to the end of the transmission belt 10 away from the driven wheel 6, and the driven wheel 6 is transmission-connected to the driving wheel through the transmission belt 10.

[0037] In the above structure, by setting the driving wheel and the screw 18 structure, the powerful motor 11 can synchronously drive the two screws 18 to rotate during the operation, and the limit bar 20 drives the scraper 7 to move toward the water inlet of the main water pipe 1, so that the user does not need to manually clean the inside of the main water pipe 1, thereby improving the functionality and automation of the drain pipe.

[0038] In a preferred embodiment, the diameter of the through hole 17 is 2 cm larger than the diameter of the cross bar 19 , and the limiting strip 20 is made of stainless steel.

[0039] In the above structure, the through hole 17 and the cross bar 19 structure enable the scraper 7 to drive the scraper 7 and the limit strip 20 to move along the inner wall of the long groove 3 toward the secondary water pipe 2 when the water filter plate 8 contacts the water body and the inner wall of the through hole 17 is not threadedly connected to the outer edge of the screw rod 18, thereby utilizing the impact force of the water body to allow the scraper 7 to clean the inner wall of the main water pipe 1, and then utilizing the elasticity of the buffer spring 9 to offset the impact force of the water due to the elasticity of the buffer spring 9 after the water pressure suddenly disappears, thereby reducing the influence of the water hammer effect on the main water pipe 1 and the secondary water pipe 2, thereby improving the protective function of the drainage pipe protection mechanism and the energy utilization rate.

[0040] In a preferred embodiment, the inner walls of the main water pipe 1 , the auxiliary water pipe 2 and the connecting pipe 5 are all in the same cross section, and the screw rod 18 can be threadedly connected to the inner wall of the through hole 17 after the buffer spring 9 is extended to the limit state.

[0041] In the above structure, the inner walls of the main water pipe 1, the auxiliary water pipe 2 and the connecting pipe 5 can provide space for the movement of the scraper 7 and the water filter plate 8, thereby ensuring that the inner walls of the main water pipe 1, the auxiliary water pipe 2 and the connecting pipe 5 can be cleaned, making it convenient for users to maintain the drain pipe. After being compressed, the buffer spring 9 can provide space for the movement of the scraper 7, thereby increasing the range of movement of the scraper 7 and the water filter plate 8 and the cleaning effect on the main water pipe 1.

[0042] In a preferred embodiment, the outer wall of the connecting pipe 5 is provided with threads, and after the connecting pipe 5 rotates clockwise along the inner wall of the docking groove 12 for 20 circles, the position of the threaded hole 14 on the slider 21 corresponds to the position of the threaded hole 14 on the main water pipe 1 .

[0043] In the above structure, the threaded and docking groove 12 structures are provided so that the connecting pipe 5 can be extended into the interior of the main water pipe 1, and the threaded hole 14 on the slider 21 can always be on the same center line with the threaded hole 14 on the main water pipe 1 through the threaded connection, so that the user can fix the two easily and avoid position displacement, thereby improving the user's assembly efficiency of the drain pipe.

[0044] Working principle: first, the user aligns the slider 21 on the connecting pipe 5 with the square groove 15, then pushes the auxiliary water pipe 2 so that the slider 21 extends into the docking groove 12, then rotates the auxiliary water pipe 2 so that the connecting pipe 5 moves toward the main water pipe 1 along the inner wall of the docking groove 12. After 20 rotations, the position of the threaded hole 14 on the slider 21 coincides with the position of the threaded hole 14 on the main water pipe 1. Then, the auxiliary water pipe 2 is fixed to the main water pipe 1 together with the connecting pipe 5 through the connecting bolt 22, and then the buffer spring is tightened. 9 penetrates the inner wall of the long groove 3 in the auxiliary water pipe 2 and is fixed to the outer wall of the driving wheel and the driven wheel 6, so that the driving wheel and the driven wheel 6 can drive the screw rod 18 to rotate when they rotate. At this point, the installation operation is completed. When drainage begins, water enters the main water pipe 1 from the end away from the auxiliary water pipe 2, and then the water contacts the water filter plate 8, so that the water filter plate 8 drives the scraper 7 and the limit strip 20 to move toward the auxiliary water pipe 2. At this time, the buffer spring 9 begins to compress, and the movement of the scraper 7 will cause the inner wall of the auxiliary water pipe 2 to move. The scraper 7 is used to clean the impurities adhered to the inner wall of the auxiliary water pipe 2 by the impact force of the water body, thereby improving the energy utilization rate of the drainage pipe. If the water pump is powered off or the water pressure disappears, the elasticity of the buffer spring 9 will cause the scraper 7 to apply thrust to the water body, thereby offsetting the impact force of the water body, thereby reducing the water hammer effect on the main water pipe 1, the auxiliary water pipe 2, and the connecting pipe 5, and extending the service life of the drainage pipe. When the water pipe needs to be maintained after the drainage is completed, the main water pipe 1 is first removed, and the elasticity of the buffer spring 9 will push the scraper 7 to reset until the inner wall of the through hole 17 contacts the screw rod 18, and then the user can drive the buffer spring 9 to rotate through the output shaft of the powerful motor 11, and the buffer spring 9 will drive the screw rod 18 to rotate, so that the limit strip 20 drives the scraper 7 to slide along the inner wall of the connecting pipe 5 and the main water pipe 1, thereby automatically cleaning the inner wall of the main water pipe 1, which is convenient for the user to perform maintenance operations.
