[0002] Building water supply and drainage pipes are a component of the building's internal water supply and drainage system. They encompass a series of pipeline facilities used for transporting and distributing domestic water and discharging wastewater and sewage. To prevent blockages inside the pipes, anti-blockage devices are generally installed on the pipes to prevent blockages.

[0003] For example, the authorized patent with announcement number CN219508742U (An anti-clogging device for building water supply and drainage pipes) includes an inlet pipe, an installation ring fitted onto the inlet pipe, two symmetrical threaded holes on the side wall of the installation ring, a threaded hole in the inlet pipe that matches the installation ring, the threaded hole of the installation ring and the inlet pipe being fixedly connected by bolts, two symmetrical grooves on the side wall of the installation ring, a limit rod fixedly connected inside the grooves, an L-shaped pressure block slidably connected to the upper part of the limit rod, the pressure block including a horizontal plate and a vertical plate, and a connecting plate movably connected inside the inlet pipe;

[0004] While the aforementioned existing technologies prevent clogging of the inner wall, they lack a scraping structure. Consequently, when filtering water through the pipes, impurities adhere to the surface of the filter screen, affecting water flow. Therefore, there is an urgent market need to develop an anti-clogging device for building water supply and drainage pipes to help people solve existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-clogging device for building water supply and drainage pipes, so as to solve the problem mentioned in the background art that when water is filtered to prevent pipe blockage, impurities will adhere to the surface of the filter screen and affect the flow of water.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging device for building water supply and drainage pipes, comprising a first water supply pipe, an anti-clogging box provided on one side of the first water supply pipe, a second water supply pipe provided on one side of the anti-clogging box, a filter screen plate fixedly installed on the end face of the anti-clogging box facing the second water supply pipe, a scraping component provided on one side of the filter screen plate, the scraping component including a circular plate and an arc-shaped scraper, and a driving component provided on the other side of the filter screen plate, the driving component including a mounting column, a rotating rod and a spiral blade.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets up a scraping component and a driving component in the anti-clogging box to work together. The spiral blades in the driving component rotate with the water flow to drive the rotating rod to rotate, which in turn causes the circular plate connected to the rotating rod to rotate. The three arc-shaped scrapers fixed on the outside of the circular plate are in close contact with the filter screen plate, which can scrape the surface of the filter screen plate in real time, effectively preventing the adhesion and accumulation of impurities, ensuring the good filtration performance of the filter screen plate, ensuring that the water can pass smoothly, maintaining a stable flow state, avoiding water flow obstruction caused by impurities, improving the operating efficiency and reliability of the entire building water supply and drainage pipeline system, and increasing its practicality.

[0015] (2) This utility model sets up a flow guide tube, which is divided into a cylindrical section one, a conical section and a cylindrical section two. The conical section and the cylindrical section of the flow guide tube are combined to form a gradually narrowing flow channel, which can accelerate the water flow speed through the spiral blades and improve the driving efficiency of the spiral blades.

[0016] (3) The utility model provides a ring sleeve on one end of the outer side of the rotating rod and a fixed rod is fixedly installed on the outer side of the ring sleeve.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5This utility model provides an embodiment of an anti-clogging device for building water supply and drainage pipes, including a water supply pipe 1, an anti-clogging box 2 on one side of the water supply pipe 1, a second water supply pipe 5 on one side of the anti-clogging box 2, a filter screen plate 9 fixedly installed on the end face of the anti-clogging box 2 facing the second water supply pipe 5, a scraping component 10 on one side of the filter screen plate 9, the scraping component 10 including a circular plate 1001 and an arc-shaped scraper 1002, and a driving component 11 on the other side of the filter screen plate 9, the driving component 11 including a mounting column. 1101, rotating rod 1102 and spiral blade 1103, three arc-shaped scrapers 1002 are provided and fixedly installed on the outside of the circular plate 1001, the arc-shaped scrapers 1002 are in close contact with the filter screen plate 9, the mounting column 1101 passes through the filter screen plate 9 and is fixedly connected to the filter screen plate 9, the rotating rod 1102 is provided on one side of the mounting column 1101, and one end of the rotating rod 1102 slides through the mounting column 1101 and is fixedly connected to the circular plate 1001, and the spiral blade 1103 is fixedly installed on the outside of the rotating rod 1102.

[0025] In the drive assembly 11, the spiral blades 1103 rotate under the flow of filtered water, driving the rotating rod 1102 to rotate, which in turn causes the circular plate 1001 connected to the rotating rod to rotate clockwise. The three arc-shaped scrapers 1002 fixed on the outer side of the circular plate 1001 are in close contact with the filter screen 9, and can scrape the surface of the filter screen 9 in real time. Through the arc-shaped setting of the arc-shaped scrapers 1002, impurities are moved to the outside, ensuring the filtration performance of the filter screen, ensuring that the water can pass through smoothly, and increasing practicality.

[0026] Please see Figure 1 One side of the anti-blocking box 2 is fixedly installed with a connecting pipe 3, and the connecting pipe 3 is fixedly connected to the water supply pipe 1. The other side of the anti-blocking box 2 is fixedly installed with a connecting pipe 4, and the connecting pipe 4 is fixedly connected to the water supply pipe 5.

[0027] Connector 3 and connector 4 are fixedly connected to the water supply pipe and anti-clogging box 2, respectively, forming a stable pipe transition structure. This ensures smooth water flow into anti-clogging box 2 for filtration, increasing practicality.

[0028] Please see Figure 2 and Figure 4 The drive assembly 11 is located inside the second connector 4. One end of the outer side of the rotating rod 1102 is movably fitted with a ring sleeve 13. A fixing rod 14 is fixedly installed on the outer side of the ring sleeve 13, and the fixing rod 14 is fixedly connected to the second connector 4. There are four fixing rods 14, which are located above, below, at the front end and at the rear end of the ring sleeve 13, respectively.

[0029] The rotating rod 1102 forms a movable support with the connecting pipe 4 through the ring sleeve 13 and the fixed rod 14, which allows the rotating rod 1102 to rotate freely while preventing it from deviating, thus ensuring the stability of the spiral blade 1103 and the scraping assembly 10.

[0030] Please see Figure 2 and Figure 5 Inside the second connector 4, a guide tube 12 is installed along the outer side of the spiral blade 1103. The guide tube 12 includes a first cylindrical section 1201, a conical section 1202, and a second cylindrical section 1203. The first cylindrical section 1201, the conical section 1202, and the second cylindrical section 1203 are arranged sequentially from left to right. The diameter of the first cylindrical section 1201 is larger than the diameter of the second cylindrical section 1203. The first cylindrical section 1201 is fixedly connected to the second connector 4.

[0031] The larger diameter of the first cylindrical section 1201 reduces the water inlet resistance, while the constricted structure of the second cylindrical section 1203 enhances the water flow guidance, ensuring that the helical blades obtain greater torque. The conical section 1202 of the guide tube 12, combined with the cylindrical section, forms a gradually narrowing flow channel, which can accelerate the water flow velocity passing through the helical blades 1103, improve the driving efficiency of the helical blades 1103, optimize the hydraulic energy conversion rate, enable the scraping component to operate under low flow conditions, and increase practicality.

[0032] Please see Figure 1 A collection base box 6 is fixedly installed below the anti-blocking box 2, and the anti-blocking box 2 is connected to the collection base box 6. A box cover 8 is fixedly installed on one side of the collection base box 6 by screws, and a box cover 7 is fixedly installed on the top of the anti-blocking box 2 by screws.

[0033] The design of connecting the bottom collection box 6 with the anti-clogging box 2 allows impurities to fall into the bottom collection box 6. The box cover 7 and the box cover 8 are fixed with screws, which makes it easy to open and close for cleaning or maintenance of impurities, increasing practicality.

[0034] Working principle: During use, water flows from water supply pipe 1 through connector 3 into anti-clogging box 2. First, it passes through filter screen 9 to filter impurities. When the filtered water flows into connector 4, it drives the spiral blade 1103 to rotate, which in turn drives the rotating rod 1102 and the circular plate 1001 to rotate. This causes the three arc-shaped scrapers 1002 to continuously scrape the impurities attached to the surface of filter screen 9. Through the arc-shaped setting of the arc-shaped scrapers 1002, the impurities are moved to the outside. The tapered structure of the guide tube 12 accelerates the water flow and enhances the driving force of the spiral blade 1103, ensuring that the scraping assembly 10 can still operate effectively at low flow rates. Then, the water is output through water supply pipe 5.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
