[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Example:

[0017] refer to Figures 1 to 4As shown, a tunnel segment cleaning device is disclosed, including a mobile carrier 1, a water platform 2 at the rear of the mobile carrier 1, a protective frame 3 on the water platform 2, a water tank 4, a water pump 5, and two support frames 6, all fixedly connected to the water platform 2, and a pipe winding disc 7 between the two support frames 6. A first connecting water pipe 8 is wound on the pipe winding disc 7. A drain pipe 9 is provided at the bottom of the water tank 4. A first control valve 10 and a second control valve 11 are provided on the drain pipe 9. The connection between the water pump 5 and the drain pipe 9 is located between the first control valve 10 and the second control valve 11. A vertically arranged water guide pipe 12 is provided at the water outlet end of the water pump 5. One end of the first connecting water pipe 8 is connected to the water guide pipe 12, and the other end is connected to a second connecting water pipe 13. A fixed pipe 14 is provided at the water outlet end of the second connecting water pipe 13. A water nozzle 15 is provided on the fixed pipe 14. An angle adjustment device for fixing the fixed pipe 14 is provided on the protective frame 3.

[0018] In this invention, by mounting the entire device on a mobile carrier 1, it is easy to move the device to the depths of the tunnel for cleaning operations. Simultaneously, the water pump 5 pumps water from the water tank 4 through the drain pipe 9, the guide pipe 12, the first connecting water pipe 8, the second connecting water pipe 13, and the fixed pipe 14, and finally discharges the water through the water nozzle 15. During operation, the fixed pipe 14 can be connected to the angle adjustment device, thereby facilitating the mobile spray cleaning of tunnel segments at the same angle as the mobile carrier 1 moves, thus improving cleaning efficiency.

[0019] During the cleaning process, for areas with a lot of dirt on the tunnel segments, the second connecting water pipe 13 can be directly connected to the water guide pipe 12, and personnel can use the fixed pipe 14 to spray the water at specific points. Alternatively, the fixed pipe 14 can be connected to the angle adjustment device for long-term rinsing to achieve the cleaning purpose.

[0020] During the cleaning process, the first connecting water pipe 8 can also be removed from the pipe coil 7, and the tunnel segments can be cleaned by personnel holding the fixed pipe 14. This makes it easier to increase the area of ​​spray cleaning through the first connecting water pipe 8 when the mobile carrier 1 stops moving.

[0021] In this utility model, the mobile carrier 1 is a mobile vehicle.

[0022] The angle adjustment device includes a mounting plate 16 connected to the protective frame 3. The front side of the mounting plate 16 is provided with a square through hole 17. Both side walls of the square through hole 17 are provided with vertically arranged first sliding grooves 18. The front side of the mounting plate 16 and both sides of the through hole are provided with vertically arranged openings 19, and both openings 19 are connected to the adjacent first sliding grooves 18. Sliding blocks 20 are slidably arranged in both first sliding grooves 18. A fixing block 21 is provided between the two sliding blocks 20.

[0023] During installation, the fixing tube 14 is inserted into the mounting through hole 22. When it is necessary to adjust the vertical position of the fixing tube 14, the sliding block 20 is moved up and down in the first sliding groove 18. After adjusting to the appropriate position, the adjusting nut is rotated to make the nut tightly abut against the mounting plate 16. At this time, the sliding block 20 is restricted from sliding in the first sliding groove 18, thereby fixing the height of the fixing tube 14.

[0024] Connecting posts 24 are fixedly provided on both sides of the fixed block 21. The sliding block 20 has a connecting hole on the side facing the fixed block 21. The sliding block 20 has a spherical limiting hole that communicates with the connecting hole. The side of the connecting post 24 away from the fixed block 21 passes through the connecting hole and is connected to the limiting ball block 25 provided in the spherical limiting hole.

[0025] When the fixed block 21 rotates, it drives the connecting column 24 and the limiting ball block 25 to rotate synchronously, which facilitates the adjustment of the water outlet direction of the fixed pipe 14. At the same time, the limiting ball block 25 prevents the fixed block 21 and the sliding block 20 from disengaging.

[0026] The water platform 2 is provided with a first column 26, the top of the first column 26 is provided with a second sliding groove, and a second column 27 is slidably provided in the second sliding groove. One side of the first column 26 is provided with a screw hole that communicates with the second sliding groove. A second stud 28 is threadedly connected in the screw hole. One end of the second stud 28 abuts against the second column 27, and the other end is connected to a rotating hand ring 29 provided on the outside of the first column 26. The top of the second column 27 is connected with a collar 30 for fitting the second connecting water pipe 13.

[0027] By fitting the second connecting water pipe 13 onto the collar 30, adjusting the position and height of the second column 27, and rotating the hand ring 29 by hand, stable support is provided for the second connecting water pipe 13. Preferably, the second connecting water pipe 13 here is a rigid PE pipe.
