Embodiment 1

[0024] Reference Figure 1-Figure 4 The anti-rotation mechanism 9 includes an installation box 91 fixed on the top of the upper end cover 5, a cross bar 92 is fixed in the installation box 91, a moving block 93 is slidably provided on the outer surface of the cross bar 92, a limiting groove block 94 is fixed on one side of the moving block 93 close to the limiting tooth 8, the limiting groove block 94 slides on the inner wall of the installation box 91, and the limiting groove block 94 is engaged with the limiting tooth 8.

[0025] Reference Figure 1-Figure 4 The anti-rotation mechanism 9 also includes a return spring 95 disposed in the mounting box 91 , and both ends of the return spring 95 are fixedly connected to the moving block 93 and the mounting box 91 , respectively.

[0026] Reference Figure 1-Figure 4The anti-rotation mechanism 9 also includes a slide groove 96 opened on the side wall of the installation box 91, and a moving bar 97 is fixed to the side of the moving block 93, and the moving bar 97 slides in the slide groove 96.

[0027] In the utility model, when in use, the lower end cover 1 is installed on the pipeline, and water flows into the lower end cover 1 from the water inlet 2. When a certain amount of water accumulates inside the lower end cover 1, the float 4 will rise with the rise of the water level. When the float 4 reaches the set position, it will trigger the opening of the lower end cover 1, allowing water to flow out of the pipeline system from the water outlet 3. When the water level drops, the float 4 will also drop, eventually causing the water outlet 3 to close, stop draining, and realize automatic drainage. By installing the upper end cover 5 on the top of the lower end cover 1, the upper end cover 5 can be removed, which is convenient for detecting the devices inside the lower end cover 1. When installing the upper end cover 5, the upper end cover 5 is placed on the top of the lower end cover 1, so that the stud 6 passes through the inside of the upper end cover 5, and the upper end cover 5 is initially installed. Then, the moving bar 97 is slid backward in the slide groove 96, and the moving bar 97 drives the moving block 93 to slide backward on the outer surface of the cross bar 92, squeezing the reset spring 95, so that the limiting groove block 94 moves backward together, and the threaded disk 7 is rotated to screw into the outer surface of the stud 6 to fix the upper end cover 5. At this time, the moving bar 97 can be loosened, and the elastic force of the reset spring 95 can be used to drive the moving block 93 and the limiting groove block 94 to move forward, and the limiting groove block 94 can be used to limit the limiting tooth 8. This design can prevent the threaded disk 7 from rotating, thereby preventing the threaded disk 7 from falling off from the outer surface of the stud 6 after being impacted by water for a long time, causing the upper end cover 5 to separate from the lower end cover 1, affecting the use effect and improving safety.
