[0031] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0032] like Figure 1-5 As shown, an anti-seepage structure for an assembled building external water supply and drainage engineering project comprises a water receiving pipe 1 with an opening at the top, a connecting pipe 2 is fixedly installed at the bottom of the water receiving pipe 1, a drainage pipe 3 is arranged at one end of the connecting pipe 2, a water hole 4 communicating with the connecting pipe 2 is penetrated on the inner wall of the bottom of the water receiving pipe 1, a filter pipe 5 communicating with the water hole 4 is arranged in the connecting pipe 2, a plurality of leakage holes 6 evenly arranged are penetrated on the filter pipe 5, a floating body 7 is arranged in the filter pipe 5, the floating body 7 is slidably connected to the inner wall of the water hole 4, a T-shaped bracket 8 is fixedly installed on the bottom of the floating body 7, and a T-shaped bracket 8 is fixed on the T-shaped bracket 8 The fixed sleeve is provided with a circular ring 9, and the circular ring 9 is slidably installed in the filter tube 5. The water receiving pipe 1 is provided with a filter screen cover 11, and a pressure rod 12 is fixedly installed at the bottom of the filter screen cover 11. The pressure rod 12 passes through the water hole 4. Through a simple anti-backflow leakage structure, it can effectively prevent backflow leakage in the water supply and drainage pipes, and can effectively avoid the problem that the spring pulls the anti-backflow structure to be difficult to reset and block the backflow, and effectively improve the reliability of the anti-backflow structure. The water receiving pipe 1 also includes a first annular clamp 10, which is slidably installed in the water receiving pipe 1. The first annular clamp 10 is fixed on the filter screen. The top of the cover 11, a second annular clamp 13 is fixedly installed in the water receiving pipe 1, the second annular clamp 13 contacts the bottom of the first annular clamp 10, and two handles 14 are fixedly installed on the top of the first annular clamp 10. Through this arrangement, it is convenient to quickly disassemble the filter screen cover 11, and then it is convenient to clean up the debris attached to the filter screen cover 11, which can effectively ensure the water flow effect of the filter screen cover 11. An annular groove is opened on the inner wall of the water hole 4, and a sealing ring is fixedly installed in the annular groove. The sealing ring is slidably connected to the float 7. By setting the annular groove and the sealing ring A circle is formed, thereby preventing water leakage when the water hole 4 is blocked. A round tube is provided at the bottom of the water receiving pipe 1. The round tube is slidably installed in the connecting pipe 2. The round tube is fixedly sleeved on the filter tube 5. By setting the round tube, it is convenient to fix the filter tube 5. The pressure rod 12 is made of rubber. Through this arrangement, it is possible to prevent the pressure rod 12 from damaging the float 7. The handle 14 is an L-shaped structure. Through this arrangement, it is convenient to lift the filter screen cover 11. The filter screen cover 11 is a bowl-shaped structure. The filter screen cover 11 passes through the second annular clamp 13. Through this arrangement, it is convenient to effectively filter debris.
[0033] The working principle of the utility model is as follows: when in use, water is discharged into the water receiving pipe 1 and then filtered through the filter screen cover 11. The filtered water enters the filter tube 5 through the water flow hole 4. The water in the filter tube 5 enters the connecting pipe 2 through multiple leakage holes 6 and is then discharged through the drain pipe 3. When the drain pipe 3 or the connecting pipe 2 is blocked, the water level in the connecting pipe 2 rises, and the water in the connecting pipe 2 enters the filter tube 5 through the leakage holes 6. The water level in the filter tube 5 rises, causing the float 7 to float up. The float 7 drives the T-shaped bracket 8 to rise as the water level rises, so that the ring 9 is driven to slide and rise in the filter tube 5 until the float 7 contacts the pressure rod 12. The water level continues to rise, causing the float 7 to be driven to continue to rise. The float 7 pushes the pressure rod 12 upward, so that the filter screen cover 11 is pushed up, and the filter screen cover 11 drives the first annular clamp 10 to slide and rise in the water receiving pipe 1 until the float 7 slides into the water flow hole 4, so that the water flow hole 4 is blocked, and the water in the filter tube 5 stops flowing back. The water level drops after the filter screen 11 is unblocked and the pressure drop is increased. The pressure rod 12 pushes the float 7 downward from the water hole 4 under the action of the gravity of the filter screen cover 11 and the first annular clamp 10. The water hole 4 is unblocked again and the water can be drained. Through this arrangement, the water leakage of the water supply and drainage pipe can be effectively prevented, and the problem of the spring pulling anti-backflow structure being difficult to reset and block the backflow can be effectively avoided, which effectively improves the reliability of the anti-backflow structure. When it is necessary to clean the debris attached to the filter screen cover 11, the two handles 14 are first pulled, so that the first annular clamp 10 is driven to slide out of the water receiving pipe 1, so that the filter screen cover 11 is taken out of the water receiving pipe 1, and then the debris attached to the filter screen cover 11 can be cleaned. Through this arrangement, it is convenient to quickly disassemble the filter screen cover 11, and then it is convenient to clean the debris attached to the filter screen cover 11, which can effectively ensure the water passing effect of the filter screen cover 11.
