[0018] Refer to Figures 1 - 3 , a maintenance wear detection device for pump station units, including two connecting half-rings 1, the left sides of the two connecting half-rings 1 are hinged, and connecting blocks 2 are fixedly connected to the right sides of the two connecting half-rings 1;

[0019] Among them, a pressure detection component 6 is installed at the lower end of the upper connecting half-ring 1, and a distance detection component 7 is installed at the upper end of the lower connecting half-ring 1. Both the pressure detection component 6 and the distance detection component 7 are prior arts. Specifically, refer to the distance sensor and pressure sensor parts with the publication number of CN220084321U;

[0020] Among them, a positioning mechanism is further included. The positioning mechanism includes a hollow box 4 fixedly connected to the lower end of the lower connecting half-ring 1. A plurality of first piston cylinders 11 are fixedly connected to the inner top of the hollow box 4. A first piston block 13 that can slide up and down is arranged in each first piston cylinder 11. Two second piston cylinders 3 are installed on the inner side of each connecting half-ring 1. A slidable second piston block is arranged in each second piston cylinder 3. A positioning rod 9 is fixedly connected to each second piston block. A ball is installed at the other end of each positioning rod 9. Each second piston cylinder 3 is communicated with the corresponding first piston cylinder 11 through a connecting hose 8. The top space of each first piston cylinder 11, the connecting hose 8, and the space on the side of the second piston cylinder 3 away from the second piston block are all filled with oil;

[0021] Among them, a threaded rod 5 is rotatably connected to the inner top of the hollow box 4. The lower end of the threaded rod 5 penetrates through the inner bottom of the hollow box 4. The lower ends of a plurality of first piston blocks 13 are fixedly connected with piston rods 12. The lower ends of the plurality of piston rods 12 are fixedly connected with a sliding plate 10 together. The threaded rod 5 penetrates through the sliding plate 10 and is threadedly connected with the sliding plate 10. The threaded rod 5 here adopts high-density threads, so it has a certain self-locking ability;

[0022] Among them, a connecting mechanism is further included. The connecting mechanism is used to connect two connecting blocks 2. The connecting mechanism includes an L-shaped plate 14 fixedly connected to the right side of the upper connecting block 2.

Then, the two connecting half-rings 1 are clamped on the rotating shaft. Then, rotate the upper connecting half-ring 1 back and loosen the pulling plate 15. Under the elastic action of the spring 16, the plug plate 17 will be inserted into the slot 18 to complete the limit. At this time, the rotating shaft is located inside the two connecting half-rings 1;
