Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] like Figure 1-Figure 3 As shown, the present application provides a drainage pipe for a water conservancy and hydropower project, including a drainage pipe assembly 10, which is used to discharge flood water or remove excess water, thereby preventing the facility from suffering from excessive water pressure. The drainage pipe assembly 10 includes a pipe body 11, and both ends of the pipe body 11 are fixedly installed with a fixing ring 12, and the fixing ring 12 can be spliced ​​with an external fixing ring 12. At the same time, a plurality of fixing holes 13 are opened on the fixing ring 12, and bolts a14 are provided inside the fixing holes 13. When splicing between two drainage pipes, the fixing rings 12 on the two drainage pipes can be aligned with each other, so that the fixing holes 13 can be in one position, and then the bolts a14 are respectively passed through the two groups of fixing holes 13, so that the splicing and combination work between the two drainage pipes can be completed.

[0025] Several groups of baffles 16 are provided inside the tube body 11. The baffles 16 are semicircular in shape. At the same time, an annular groove 15 that is compatible with the baffles 16 is opened on the inner wall of the tube body 11. The baffles 16 can be snapped into the annular groove 15, so that the baffles 16 can be initially installed at the annular groove 15. When water flows through the inside of the tube body 11, the water flow will come into contact with several groups of baffles 16, so that the baffles 16 can reduce the turbulence of the water flow or reduce the drastic changes in the water flow, thereby making the drainage of the drain pipe assembly 10 more stable and smooth.

[0026] At the same time, several groups of baffles 16 are provided with water outlet grooves 17. When the water flow inside the tube body 11 passes through the baffles 16, it will pass through the water outlet grooves 17, so that the water flow will pass through a more orderly path through the water outlet grooves 17, avoiding turbulence or turbulence of the water flow, thereby improving drainage efficiency and water flow speed, and the baffles 16 can filter out debris in the water flow passing through the tube body 11.

[0027] Connecting rods 18 are fixedly mounted on several groups of baffles 16, and the two ends of the connecting rods 18 can be located on both sides of the tube body 11, so that the connecting rods 18 can be held by the staff, and as the connecting rods 18 are held, the connecting rods 18 can move the several groups of baffles 16, so that the several groups of baffles 16 can be quickly moved and disassembled in the annular groove 15 and the inside of the tube body 11, and the use efficiency of the baffles 16 is improved.

[0028] Several groups of fixing blocks b111 are fixedly installed on the inner wall of the tube body 11, and a fixing block a19 is fixedly installed on the connecting rod 18 near the fixing block b111. A bolt b110 is provided on the fixing block a19, and the fixing block a19 and the fixing block b111 can be aligned. The bolt b110 can pass through the fixing block a19 and connect with the fixing block b111. When the fixing block a19 is aligned with one group of fixing blocks b111, the bolt b110 is passed through the fixing block a19 and the fixing block b111 respectively, so that the connecting rod 18 can be fixed inside the tube body 11, so that the baffle 16 can be fixed for a second time inside the tube body 11, and the stability of the baffle 16 is improved. In addition, since several groups of fixing blocks b111 are provided on the inner wall of the tube body 11, the baffle 16 can be located at different positions inside the tube body 11, thereby facilitating the position adjustment of the baffle 16 to adapt to different angles.
