[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a waterproof structure with self-cleaning function for building engineering, including a waterproof box 1, a filter screen 2 fixedly connected inside the waterproof box 1, a support 3 fixedly connected inside the waterproof box 1, a motor 4 fixedly connected to the outer wall of the support 3, a turntable 5 fixedly connected to the output end of the motor 4, a fixed column 6 fixedly connected to the outer wall of the turntable 5, a rotating rod 7 provided on the outer wall of the fixed column 6, a fixed shaft 8 rotatably connected inside the rotating rod 7, the outer wall of the fixed shaft 8 fixedly connected to the inside of the support 3, a connecting shaft 9 rotatably connected inside the fixed shaft 8, a rotating plate 10 fixedly connected to the outer wall of the connecting shaft 9, a rotating shaft 11 fixedly connected inside the rotating plate 10, a sliding rod 12 rotatably connected to the outer wall of the rotating shaft 11, the outer wall of the sliding rod 12 slidably connected to the inner wall of the support 3, a cleaning brush 13 fixedly connected to the outer wall of the sliding rod 12, the outer wall of the cleaning brush 13 slidably connected to the outer wall of the filter screen 2, and a cleaning component provided on the upper surface of the waterproof box 1 for cleaning the filter screen 2.
[0024] Specifically, the bracket 3 is fixed inside the waterproof box 1 and serves to fix the motor 4. The motor 4 can make the fixed column 6 rotate through the rotation of the turntable 5, which in turn makes the rotating rod 7 rotate through the rotation of the fixed column 6. The fixed shaft 8 is fixed inside the bracket 3 and supports the rotating rod 7, which in turn makes the rotating plate 10 rotate through the connecting shaft 9, so that the slide rod 12 slides on the inner wall of the bracket 3 through the rotating shaft 11. The bracket 3 supports the slide rod 12 and provides stable support for the reciprocating motion of the slide rod 12.
[0025] Reference Figure 1 and Figure 3 The cleaning components include a cleaning brush 13, the outer wall of which is fixedly connected to the outer wall of the slide bar 12, and the outer wall of the cleaning brush 13 is slidably connected to the outer wall of the filter screen 2. A first guide block 14 is fixedly connected to the upper surface of the waterproof box 1, a second guide block 15 is fixedly connected to the upper surface of the waterproof box 1, a filter plate 18 is fixedly connected to the upper surface of the waterproof box 1, the outer wall of the filter plate 18 is fixedly connected to the outer wall of the first guide block 14, the outer wall of the filter plate 18 is fixedly connected to the outer wall of the second guide block 15, and a water outlet 17 is fixedly connected to the inside of the waterproof box 1.
[0026] Specifically, the reciprocating motion of the slide bar 12 causes the cleaning brush 13 to reciprocate and clean the filter screen 2 through the slide bar 12. Since the filter screen 2 is equipped with cleaning brushes 13 on both sides, both sides of the filter screen 2 can be cleaned to achieve all-round cleaning and prevent clogging. The first guide block 14 and the second guide block 15 can effectively guide the water flow direction. The filter plate 18 can perform preliminary filtration of excessively large impurities in the water. The water outlet 17 can drain water.
[0027] Reference Figure 1 and Figure 4 A triangular guide block 16 is fixedly connected to the upper surface of the waterproof tank 1. A waterproof layer 19 is provided inside the triangular guide block 16. A self-cleaning coating 20 is provided on the lower surface of the waterproof layer 19. A protective layer 21 is provided on the lower surface of the self-cleaning coating 20. An isolation layer 22 is provided on the lower surface of the protective layer 21. A drainage layer 23 is provided on the lower surface of the isolation layer 22. The waterproof layer 19 is made of polyurethane waterproof coating. The self-cleaning coating 20 is made of photocatalytic material. The protective layer 21 is made of polyurethane film. The drainage layer 23 is made of polypropylene.
[0028] Specifically, the triangular guide block 16 effectively guides water flow; the polyurethane waterproof coating effectively covers the building surface, forming a continuous and seamless waterproof membrane with good extensibility, adapting to minor deformations of the building; the photocatalytic material uses photocatalytically active materials to decompose stains and organic matter, not only having a self-cleaning function but also purifying the air; the polyurethane membrane prevents ultraviolet rays, acids, and alkalis, improving the service life of the waterproof system; the polyethylene film has strong water resistance and impermeability, preventing damage from external friction and chemicals; and the polypropylene drainage board has a textured surface, which not only drains water but also effectively disperses water pressure.
[0029] Working principle: When this waterproof structure is needed, the shapes of the first guide block 14, the second guide block 15, and the triangular guide block 16 effectively guide the water. The water flows into the interior of the waterproof tank 1 through the filter plate 18, where it filters out larger impurities. The interior of the waterproof tank 1 is equipped with a filter screen 2, which filters out fine impurities. The motor 4 on the outer wall of the support 3 is activated, causing the turntable 5 to rotate. When the turntable 5 rotates, it simultaneously rotates the fixed column 6 on the outer wall. The fixed column 6 is positioned inside the rotating rod 7. The wall slides and rotates, simultaneously causing the rotating rod 7 to rotate on the outer wall of the fixed shaft 8. When the rotating rod 7 rotates, it drives the rotating plate 10 to rotate via the connecting shaft 9. During the rotation of the rotating plate 10, it drives the sliding rod 12 to slide on the inner wall of the bracket 3 via the rotating shaft 11. When the sliding rod 12 slides, it drives the cleaning brush 13 to slide, thereby cleaning the filter screen 2. Cleaning brushes 13 are provided on both sides of the filter screen 2, which can clean the filter screen 2 from all directions to prevent clogging. Water is discharged from the outlet 17, achieving automatic cleaning of the filter screen 2 during the waterproofing process, avoiding long-term water leakage. The use of a clogging filter 2 affects the service life of the waterproof box 1. The waterproof layer 19 prevents water penetration and ensures the structural safety of the building. Polyurethane has excellent elasticity, water resistance, and chemical corrosion resistance, and can form a seamless waterproof membrane. The self-cleaning coating 20 can work under ultraviolet radiation and can decompose harmful gases and pollutants in the air, preventing dirt accumulation. The protective layer 21 can increase the weather resistance and corrosion resistance of the waterproof layer 19, which helps to extend the service life of the waterproof system. The isolation layer 22 has strong water resistance and impermeability, which can effectively isolate the direct contact between the waterproof layer 19 and the base material. The drainage layer 23 has an uneven surface structure, which has strong drainage capacity and pressure resistance, thus preventing external water sources from penetrating into the building and ensuring the long-term stability of the building project. This structure can not only achieve the effect of automatic cleaning during use to avoid clogging the filter and extend the service life of the waterproof structure, but also achieve good drainage effect and effectively disperse water pressure through the combined action of various materials, thereby preventing water penetration and improving the stability of the building.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
