[0032] To address the technical problems in the background section, the following anti-corrosion water supply and drainage pipes for buildings are provided:

[0033] Combination Figure 1 - Figure 4 As shown, this utility model provides a building corrosion-resistant water supply and drainage pipe, including a building base slab 1 and a foundation base 2. A pipe body 3 is arranged inside the building base slab 1 and the foundation base 2. The inner and outer surfaces of the pipe body 3 are provided with an anti-corrosion inner layer 4 and an anti-corrosion outer layer 5. A filter mechanism 6 is arranged inside the pipe body 3, and a collection mechanism 7 and a cleaning mechanism 8 are arranged on the surface of the filter mechanism 6. The anti-corrosion inner layer 4 and the anti-corrosion outer layer 5 are respectively made of polytetrafluoroethylene and epoxy resin coating materials. The filter mechanism 6 includes a fixing ring 601, which is fixedly installed inside the pipe body 3. An installation plate 602 is arranged on the upper side of the fixing ring 601, and two grooves 603 are opened on the surface of the installation plate 602. A filter screen 604 is fixedly installed inside the grooves 603. A sealing ring 605 is bonded to the outer surface of the fixing ring 601, and the fixing ring 601 is tightly engaged with the inner wall of the pipe body 3 through the sealing ring 605.

[0034] In this embodiment: the inner anti-corrosion layer 4 is made of polytetrafluoroethylene (PTFE), which has high chemical stability and can resist corrosion from almost all chemical substances such as strong acids, strong alkalis, and organic solvents. It does not adhere to impurities and has a low coefficient of friction, effectively preventing damage to the inner wall of the pipe due to contact with corrosive media or the accumulation of impurities. The outer anti-corrosion layer 5 is made of epoxy resin coating material, which has excellent adhesion, corrosion resistance, wear resistance, and mechanical strength. It can tightly adhere to the surface of the pipe body 3, forming a robust protective layer that resists external corrosive substances and mechanical damage, providing reliable protection for the pipe body 3. The combination of the two layers is extremely effective. This improves the corrosion resistance and service life of the pipeline. The fixing ring 601 is fixedly installed inside the pipe body 3, and the sealing ring 605 is bonded to the outside to make it tightly fit with the inner wall of the pipe body 3, so as to play a good sealing role and prevent water from leaking from the gaps. The mounting plate 602 on the upper side of the fixing ring 601 is fixedly installed with the filter screen 604 through the groove 603 on its surface. When the water flows in the pipe body 3, the filter screen 604 can effectively intercept impurities in the water, prevent impurities from entering the subsequent pipeline system with the water flow, ensure the normal operation of the water supply and drainage pipeline system, and reduce the risk of pipeline blockage and equipment damage caused by impurities.

[0035] In a preferred embodiment, a plurality of screws 606 are fixedly installed on the upper surface of the fixing ring 601, and a plurality of mounting holes 607 are provided on the surface of the mounting plate 602. The plurality of screws 606 on the upper surface of the fixing ring 601 correspond to and cooperate with the plurality of mounting holes 607 on the surface of the mounting plate 602. The screws 606 pass through the mounting holes 607 and cooperate with the nuts to achieve bolt connection and fixation.

[0036] In this embodiment, multiple screws 606 fixedly installed on the upper surface of the fixing ring 601 correspond to multiple mounting holes 607 opened on the surface of the mounting plate 602. During installation, simply pass the screws 606 precisely through the mounting holes 607 and tighten the nuts to achieve a stable fixation between the fixing ring 601 and the mounting plate 602 through this bolt connection method. This connection method is simple to operate and also facilitates the subsequent disassembly, maintenance or replacement of the filter mechanism 6.

[0037] In a preferred embodiment, the collection mechanism 7 includes a placement slot 701, and two placement slots 701 are provided, both of which are opened on the upper surface of the mounting plate 602. A collection box 702 is engaged inside the placement slot 701, and multiple drainage holes 703 are opened on both sides of the collection box 702.

[0038] In this embodiment, the collection mechanism 7 has two placement slots 701 on the upper surface of the mounting plate 602, and the collection box 702 is engaged in the placement slots 701. When impurities intercepted by the filter screen 604 slide into the collection box 702, the collection box 702 can collect the impurities in a concentrated manner. Multiple drainage holes 703 on its two side surfaces can promptly drain water accumulated in the collection box 702 due to impurities or water flow, preventing excessive water accumulation in the collection box 702 from affecting the impurity collection effect. This achieves efficient and convenient impurity collection and water separation, reducing the risk of pipe blockage. The diameter of the drainage holes 703 is similar to the pore size of the filter screen 604, preventing impurities from leaking out through the drainage holes 703.

[0039] In a preferred embodiment, a slot 704 is provided inside the placement slot 701, and a locking block 705 is fixedly installed on the lower surface of the top of the collection box 702, and the locking block 705 is engaged with the slot 704.

[0040] In this embodiment, the slot 704 inside the placement groove 701 and the locking block 705 fixedly installed on the lower surface of the top of the collection box 702 cooperate and engage with each other. When installing the collection box 702, simply align the locking block 705 with the slot 704 and insert it to fix the collection box 702 in the placement groove 701. The operation is simple and convenient, improves installation efficiency, and makes it easy to remove and clean the impurities inside.

[0041] In a preferred embodiment, the cleaning mechanism 8 includes a rotating shaft 801, which is rotatably connected to the surface of the mounting plate 602. A rotating rod 802 is fixedly installed on the outside of the rotating shaft 801, and a connecting groove 803 is provided inside the rotating rod 802. A baffle 804 is slidably connected inside the connecting groove 803, and a cleaning brush 805 is fixedly installed on the lower surface of the baffle 804. A spring 806 is fixedly installed between the upper surface of the baffle 804 and the inner wall of the connecting groove 803.

[0042] In this embodiment: the rotating shaft 801 rotates on the surface of the mounting plate 602, causing the externally fixed rotating rod 802 to rotate synchronously. During the rotation of the rotating rod 802, the baffle 804 slides in the connecting groove 803, and at the same time, the cleaning brush 805 on the lower surface of the baffle 804 moves accordingly. The cleaning brush 805 contacts the surface of the filter screen 604, and uses the force generated by the rotation to brush off the impurities attached to the filter screen 604. The spring 806 installed between the upper surface of the baffle 804 and the inner wall of the connecting groove 803 can provide elasticity, so that the cleaning brush 805 always sticks tightly to the surface of the filter screen 604, ensuring the cleaning effect, effectively preventing impurities from accumulating and clogging on the filter screen 604, maintaining the normal filtration function of the filter screen 604, and ensuring the smooth operation of the water supply and drainage pipes.

[0043] In a preferred embodiment, a motor 807 is fixedly mounted on the lower surface of the mounting plate 602, and the output end of the motor 807 is fixedly connected to the rotating shaft 801. A sealing box 808 is fixedly mounted on the lower surface of the mounting plate 602 outside the motor 807.

[0044] In this embodiment: when the motor 807 starts, it can directly drive the rotating shaft 801 to rotate, thereby driving the rotating rod 802 and cleaning brush 805 and other components to work, so as to clean the filter screen 604; while the sealing box 808 fixedly installed outside the motor 807 can effectively isolate water flow and the humid environment inside the pipe, prevent the motor 807 from being damaged by moisture or water ingress, and ensure that the motor 807 operates stably in the complex water supply and drainage pipe environment.

[0045] Specifically, the working principle of this solution is as follows:

[0046] When the building's anti-corrosion water supply and drainage pipeline is in operation, the water in the pipe body 3 flows through the filter screen 604 on the mounting plate 602, and impurities are intercepted. In the collection mechanism 7, the impurities slide down to the collection box 702, which is engaged in the placement groove 701. The drainage holes 703 on both sides of the collection box 702 promptly drain the accumulated water, realizing the collection of impurities and the separation of water, reducing the risk of blockage. In addition, the collection box 702 is engaged with the groove 704 by the locking block 705, which facilitates installation, removal and cleaning.

[0047] In the cleaning mechanism 8, the motor 807 on the lower surface of the mounting plate 602 starts, and its output end drives the rotating shaft 801 to rotate, causing the rotating rod 802 to rotate synchronously. The baffle 804 slides in the connecting groove 803, and the cleaning brush 805 moves accordingly and adheres tightly to the surface of the filter screen 604. The spring 806 provides elasticity to ensure the cleaning effect and brushes off impurities. At the same time, the sealing box 808 effectively isolates water flow and humid environment, prevents damage to the motor 807, and ensures its stable operation. The anti-corrosion inner layer 4 and the anti-corrosion outer layer 5 are made of polytetrafluoroethylene and epoxy resin coating materials, respectively, which greatly improves the anti-corrosion performance and service life of the pipeline.

[0048] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
