[0023] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 - 4, the present utility model provides a technical solution: an anti-collision drainage pipe, which includes a precast cement pipe 1. One end of the precast cement pipe 1 is connected to a fixed socket part 2. On the side of the socket part 2 away from the precast cement pipe 1, there is a first end plate 6. On one side of the first end plate 6, a first socket 15 is fixedly connected. The first socket 15 is inserted into the socket part 2. In the middle position of the side of the first end plate 6 where the first socket 15 is installed, a detachable stud 10 is installed. On the side of the precast cement pipe 1 away from the socket part 2, there is a second end plate 12. On one side surface of the second end plate 12, a second socket 17 for inserting into the precast cement pipe 1 is fixedly connected. In the middle position of one side of the second end plate 12, a through hole 18 is opened. One end of the stud 10 away from the first end plate 6 passes through the precast cement pipe 1 and the through hole 18 and is threadedly connected with a nut 11, so that the first socket 15 is inserted into the socket part 2, the second socket 17 is inserted into the precast cement pipe 1, and then the stud 10 is passed through the through hole 18 and the nut 11 is screwed on to complete the assembly of the first end plate 6, the second end plate 12 and the precast cement pipe 1. Under the protection of the first end plate 6 and the second end plate 12, it is possible to prevent the precast cement pipe 1 from being damaged due to collision.

[0025] Referring to Figures 1 - 4 , two planes 4 are processed on the circumferential side surface of the first end plate 6 and the circumferential side surface of the second end plate 12. The diameter of the first end plate 6 is the same as that of the second end plate 12. The distance between the two planes 4 on the first end plate 6 is greater than the outer diameter of the socket part 2. Two blind holes 5 are processed on the plane 4. In each of the two blind holes 5, a positioning pin 3 is inserted. The length of the positioning pin 3 is twice the depth of the blind hole 5. By processing two planes 4 on the first end plate 6 and the second end plate 12, the plane 4 on the upper first end plate 6 and the plane 4 on the upper second end plate 12 are respectively aligned with the plane 4 on the lower first end plate 6 and the plane 4 on the lower second end plate 12, and the positioning pins 3 are inserted into the opposite blind holes 5, so as to realize the neat stacking of the precast cement pipes 1, improve the stacking stability. At the same time, the weight of the precast cement pipe 1 is transferred to the supporting carrier through the first end plate 6 and the second end plate 12, preventing the precast cement pipe 1 from being damaged due to extrusion, which is beneficial to increasing the stacking layers of the precast cement pipe 1.

[0026] Referring to Figure 1 and Figure 2, a U-shaped frame 9 is provided on one side of the perforation 18. Both ends of the U-shaped frame 9 are in contact with the second end plate 12. A round hole aligned with the perforation 18 is formed on one side surface of the U-shaped frame 9. The stud 10 passes through the round hole. The U-shaped frame 9 is arranged between the nut 11 and the second end plate 12. When the nut 11 is screwed onto the stud 10, one end of the stud 10 passes through the round hole on the U-shaped frame 9. Then, after the nut 11 is screwed on, the U-shaped frame 9 is between the nut 11 and the second end plate 12. When the nut 11 and the stud 10 cannot be normally separated due to rust, the stud 10 can be cut off by using the gap between the U-shaped frame 9 and the second end plate 12, and the separation of the first end plate 6, the second end plate 12 and the precast cement pipe 1 can be completed.

[0027] Refer to Figure 3 and Figure 4 , a plurality of first round openings 14 are evenly formed on one side surface of the first end plate 6. A plurality of first through openings 16 are evenly formed in the area of the first end plate 6 located inside the first socket 15. The first round openings 14 and the first through openings 16 reduce the production material consumption of the first end plate 6. A plurality of second round openings 8 are evenly formed on one side surface of the second end plate 12. A plurality of second through openings 7 are evenly formed in the area of the second end plate 12 located inside the second socket 17. The design of the second round openings 8 and the second through openings 7 reduces the production material consumption of the second end plate 12.

[0028] Refer to Figure 2 , Figure 5 and Figure 6 , a female thread sleeve 13 is fixedly connected to the middle position of the surface of the first end plate 6 facing the first socket 15. One end of the stud 10 is threadedly connected inside the female thread sleeve 13. A disc 22 is adhesively connected to the innermost side inside the female thread sleeve 13. A spring 21 arranged along the length direction of the female thread sleeve 13 is installed on one surface of the disc 22. The design of the disc 22 facilitates restricting one end of the spring 21 inside the female thread sleeve 13. A plug 20 for blocking the open end of the female thread sleeve 13 is installed on the surface of the spring 21 away from the disc 22. The plug 20 is slidably installed inside the female thread sleeve 13 and the plug 20 is in contact with the stud 10. A limiting ring 19 fixedly connected to the stud 10 is sleeved on the end of the stud 10 close to the female thread sleeve 13. The limiting ring 19 is arranged outside the female thread sleeve 13. The limiting ring 19 restricts the length of the stud 10 screwed into the female thread sleeve 13. The stud 10 is screwed into the female thread sleeve 13 to complete the assembly of the stud 10 and the first end plate 6. At this time, the stud 10 presses the plug 20, and the plug 20 presses the spring 21 to cause elastic deformation of the spring 21. When the stud 10 is separated from the female thread sleeve 13, under the action of the resilience of the spring 21, the plug 20 moves to the open end of the female thread sleeve 13, realizing real-time blocking of the female thread sleeve 13 and preventing small sundries from randomly entering the female thread sleeve 13.
