DETAILED DESCRIPTION
[0015] In order to make the technical scheme of the embodiments of the present utility model or the prior art clearer, the following will briefly introduce the drawings needed to be used in the embodiment or prior art description. Obviously, the drawings in the following description are some embodiments of the present utility model, and those skilled in the art can also obtain other drawings according to these drawings without creative labor.
[0016] A kind of building water supply and drainage is prevented and is blocked device, such asFigure 1 、 2 , as shown in figure 3, the filter cover 1 and the drain pipe 5 including fine holes, the filter cover 1 is inverted cylindrical, the first annular plate 2 is fixedly installed on the filter cover 1, the radial section of the first annular plate 2 is Z-shaped, the first annular plate 2 and the filter cover 1 enclose an annular groove 3, the second annular plate 4 is arranged in the annular groove 3, the radial section of the second annular plate 4 is L-shaped, the first annular plate 2, the second annular plate 4, the annular groove 3 and the filter cover 1 are coaxially arranged. The utility model discloses simple structure, clever design, sewage will take dirt first into the second annular plate 4 of annular groove 3, dirt is collected in the annular groove 3, and the contact with the filter cover 1 is reduced, thereby reducing the possibility of filter cover 1 blockage, when cleaning, only the second annular plate 4 is taken out, and the second annular plate 4 is washed, so that cleaning is more convenient, actual demand can be met, and the utility model discloses be suitable for promotion. When using, the device is installed on the drain pipe 5, and the top surface is flush with the ground, sewage flows to the annular groove 3 from the outside, dirt falls on the second annular plate 4, and sewage can flow to the drain pipe 5 from the top or the periphery of the filter cover 1, dirt is collected in the annular groove 3, the possibility of contact between the filter cover 1 and the dirt is greatly reduced, dirt is avoided from forming a film on the top of the filter cover 1, and drainage is affected, when the dirt in the annular groove 3 needs to be cleaned, the second annular plate 4 is taken out, when taking out, the second annular plate 4 takes out the dirt, and the inner circle of the second annular plate 4 can also scrape the dirt around the filter cover 1, since the second annular plate 4 is provided with no filter hole, the surface is flat, and the dirt on the second annular plate 4 is easily cleaned, so that cleaning is convenient, and the utility model discloses are more practical.
[0017] Specifically, as shown in the figure, a plurality of vertical rods 20 are fixedly installed in the annular groove 3, the vertical rods 20 are uniformly distributed in the circumference, a plurality of round holes 21 are formed in the second annular plate 4, and the vertical rods 20 are inserted and matched with the corresponding round holes 21. When the water flow with dirt passes through the vertical rods 20, the vertical rods 20 can play a blocking role, so that the dirt is stuck on the vertical rods 20, the dirt is avoided from being close to the filter cover 1, and the possibility of blockage is further reduced, when the dirt needs to be cleaned due to excessive accumulation, the second annular plate 4 is taken out, the dirt on the vertical rods 20 is scraped away by the round holes 21 and collected on the second annular plate 4, and cleaning is more convenient.
[0018] Specifically, as shown in the figure, a plurality of magnets 30 are fixedly installed in the annular groove 3, and the second annular plate 4 has ferromagnetic properties. When the second annular plate 4 is installed in the annular groove 3, the second annular plate 4 is attracted by the magnets 30, and the second annular plate 4 is avoided from floating up when there is water in the annular groove 3.
[0019] Further, as shown in the figure, the filter cover 1 is internally fixedly installed with an inner square cover 40, the inner square cover 40 is internally insertedly and fitly provided with a square rod 41, the square rod 41 is fixedly installed with a fan wheel 42, the fan wheel 42 is rotatably installed with a four-legged support 43, the bottom side of the fan wheel 42 is fixedly installed with a rotating rod 44, the rotating rod 44 is rotatably installed with a supporting ring 45 through a bearing, the supporting ring 45 is fixedly connected with the four-legged support 43, the fan wheel 42, the supporting ring 45, the square rod 41, the inner square cover 40 and the filter cover 1 are coaxially arranged, and the dirt discharging pipe 5 is provided with a clamping groove 46 matched with the four-legged support 43.
