[0002] Cleaning the tunnel invert is crucial in tunnel construction and maintenance. As a key component of the tunnel structure, the invert's surface easily accumulates dust, dirt, oil stains, and other impurities. If not cleaned promptly, this not only affects the tunnel's aesthetics but can also corrode the tunnel structure, reducing its service life and even impacting traffic safety. However, existing methods for cleaning tunnel inverts largely rely on manual labor, which is labor-intensive, inefficient, and yields inconsistent cleaning results. This is especially true for large-area, complex cleaning tasks, where manual cleaning falls short. Furthermore, some mechanical cleaning equipment has limited functionality and cannot meet the diverse needs of tunnel invert cleaning. Therefore, a tunnel invert cleaning device needs to be designed to address this problem. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 7 As an embodiment of the present invention, a tunnel invert arch cleaning device includes a base 1, an mounting block 2 on one side of the base 1, a fixing plate 20 fixedly mounted on the mounting block 2, vertical plates 3 symmetrically mounted on the mounting block 2, a rotating shaft 4 rotatably mounted on the vertical plates 3, a rotating plate 5 rotatably mounted on the rotating shaft 4, an adjusting groove 25 on the rotating plate 5, a telescopic member 26 mounted on the side wall of the adjusting groove 25, an installation rod 27 connected to the end of the telescopic member 26 away from the side wall of the adjusting groove 25, the installation rod 27 slidingly fitting against the inner wall of the adjusting groove 25, an installation frame 6 connected to the end of the installation rod 27 away from the telescopic member 26, an electric cleaning brush 7 mounted on the installation frame 6, a water storage chamber 10 on the mounting block 2, and a water storage chamber 10 on the side wall of the water storage chamber 10... A connecting pipe 9 is installed, and a nozzle 8 is installed at the end of the connecting pipe 9 away from the side wall of the water storage chamber 10. A suction pump is installed on the connecting pipe 9. The nozzle 8 is located on the side of the electric cleaning brush 7, and a connecting rod is installed on the nozzle 8. The end of the connecting rod away from the nozzle 8 is connected to the mounting bracket 6. A drive assembly is installed on the fixed plate 20. A swing assembly and a transmission mechanism are installed on the drive assembly. The end of the swing assembly away from the drive assembly is connected to the rotating plate 5. A stirring rod 34 is provided in the water storage chamber 10. The transmission mechanism is connected to the stirring rod 34 at a point away from the drive assembly. A lifting assembly is installed on the base 1. The end of the lifting assembly away from the base 1 is connected to the mounting block 2. A self-locking moving wheel 38 is installed at the bottom of the base 1. A pusher 28 is installed on the base 1.

[0022] In this embodiment, the device is equipped with self-locking moving wheels 38 at its bottom. Operators can push the device within the tunnel using the push handle 28 on the base 1, transporting it to the tunnel invert where cleaning is required. Upon reaching the designated location, the self-locking moving wheels 38 are locked, fixing the device in its current position and ensuring it does not move arbitrarily during cleaning, thus guaranteeing the stability and safety of the cleaning operation. When the height of the electric cleaning brush 7 needs to be adjusted to accommodate tunnel inverts of different heights, the lifting assembly is activated to raise or lower the mounting block 2. Since the electric cleaning brush 7 is mounted on related components of the mounting block 2, the movement of the mounting block 2 synchronously adjusts the height of the electric cleaning brush 7, ensuring good contact with the tunnel invert surface for effective cleaning. A stirring rod 34 is installed in the water storage chamber 10, connected to the end of the transmission mechanism furthest from the drive assembly. The drive assembly drives the transmission mechanism, which transmits power to the stirring rod 34, causing it to rotate within the water storage chamber 10. The rotation of the stirring rod 34 agitates the cleaning fluid in the water storage chamber 10, ensuring thorough and uniform mixing of all components. When cleaning fluid spraying is required, the suction pump is activated, generating suction to draw the cleaning fluid from the water storage chamber 10 through the connecting pipe 9 to the nozzle 8, from which it is sprayed onto the area on the tunnel invert surface that needs cleaning. The nozzle 8 is positioned on one side of the electric cleaning brush 7 and connected to the mounting bracket 6 via a connecting rod. This design ensures that the spraying position of the cleaning fluid matches the cleaning position of the electric cleaning brush 7, facilitating timely cleaning of the sprayed area. The end of the swing assembly furthest from the drive assembly is connected to the rotating plate 5. The swing assembly drives the rotating plate 5 to reciprocate around the rotating shaft 4. During the reciprocating swing of the rotating plate 5, the electric cleaning brush 7 swings accordingly, wiping and cleaning the surface of the tunnel invert. Meanwhile, by adjusting the telescopic length of the telescopic component 26, the position of the mounting rod 27 in the adjustment groove 25 can be changed, thereby adjusting the cleaning range and pressure of the electric cleaning brush 7 to adapt to the tunnel arch surface with different levels and sizes of dirt.

[0023] Furthermore, the telescopic component 26 can be an electric telescopic rod or an electric push rod, etc., which will not be described in detail here.

[0024] Please see Figures 1 to 7 As an embodiment of the present invention, the drive assembly includes a dual-axis motor 37, which is mounted on a fixed plate 20. The output end of the dual-axis motor 37 is respectively equipped with a first drive shaft and a second drive shaft 36. The first drive shaft passes through the fixed plate 20 and is rotatably connected to the fixed plate 20.

[0025] In this embodiment, after the dual-axis motor 37 is started, its two output ends drive the first drive shaft and the second drive shaft 36 to rotate, respectively. The first drive shaft passes through the fixed plate 20 and is rotatably connected to the fixed plate 20, providing power to the swing assembly; the second drive shaft 36 provides power to the transmission mechanism, thereby realizing the coordinated work of multiple components driven by one motor, simplifying the device structure and improving energy utilization efficiency.

[0026] Please see Figures 1-5 As an embodiment of the present invention, the swing assembly includes a turntable 21, which is mounted on a first drive shaft. A guide rod 23 is eccentrically mounted on the turntable 21. A drive plate 22 is provided on one side of the turntable 21, and a drive groove is formed on the drive plate 22. A drive rod 24 is mounted on one end of the rotating plate 5 near the drive plate 22. The drive rod 24 passes through the drive groove and slides against the inner wall of the drive groove. The guide rod 23 extends into the drive groove at the end away from the turntable 21.

[0027] In this embodiment, when the first drive shaft rotates, the turntable 21 rotates accordingly. Since the guide rod 23 is eccentrically mounted on the turntable 21, the rotation of the turntable 21 causes the guide rod 23 to perform circular motion. The guide rod 23 extends into the drive groove of the drive plate 22, and the drive plate 22 performs reciprocating linear motion under the action of the guide rod 23. The drive rod 24 of the rotating plate 5 near the drive plate 22 passes through the drive groove and slides against the inner wall of the drive groove. The reciprocating linear motion of the drive plate 22 drives the rotating plate 5 to reciprocate around the shaft 4 via the drive rod 24. An extension member 26 and a mounting rod 27 are installed in the adjustment groove 25 on the rotating plate 5. The mounting rod 27 connects the mounting frame 6 and the electric cleaning brush 7. The swinging motion of the rotating plate 5 drives the electric cleaning brush 7 to reciprocate, thereby cleaning the surface of the tunnel invert.

[0028] In one embodiment of the present invention, the transmission mechanism includes a driven shaft 14, which is rotatably connected to the top wall of the water storage chamber 10, and one end of the driven shaft 14 extends into the water storage chamber 10. A stirring rod 34 is mounted on the driven shaft 14. A connecting unit 35 is mounted on the second drive shaft 36, and the end of the connecting unit 35 away from the second drive shaft 36 is connected to the driven shaft 14. A support rod 12 is mounted on the mounting block 2, and a dust settling box 13 is connected to the end of the support rod 12 away from the mounting block 2. An installation hole is provided on the top wall of the dust settling box 13. The bottom wall of the dust collection box 13 is provided with a ventilation hole 33, a filter screen is provided in the ventilation hole 33, and a fan blade 29 is provided in the mounting hole. One end of the driven shaft 14 extends through the dust collection box 13 and into the mounting hole. The driven shaft 14 is rotatably connected to the dust collection box 13, and the fan blade 29 is installed on the driven shaft 14. The dust collection box 13 is symmetrically hinged with guide plates 11 on both sides. A sliding groove 30 is opened on the side wall of the guide plate 11. A slider 31 is slidably installed in the sliding groove 30. A fixing rod 32 is installed on one side of the slider 31. The end of the fixing rod 32 away from the slider 31 is connected to the outer wall of the rotating plate 5.

[0029] In this embodiment, when the second drive shaft 36 rotates, it drives the driven shaft 14 to rotate via the connecting unit 35. The driven shaft 14 is rotatably connected to the top wall of the water storage chamber 10 and one end extends into the water storage chamber 10. The stirring rod 34 is mounted on the driven shaft 14. The rotation of the driven shaft 14 drives the stirring rod 34 to rotate in the water storage chamber 10, stirring the cleaning liquid in the water storage chamber 10 to ensure uniform mixing and cleaning effect. One end of the driven shaft 14 passes through the dust settling box 13 and extends into the mounting hole and is rotatably connected to the dust settling box 13. The fan blade 29 is mounted on the part of the driven shaft 14 located in the mounting hole. The driven shaft 14 rotates, driving the fan blades 29 to rotate. The rotation of the fan blades 29 creates negative pressure inside the dust collection box 13, allowing outside air to enter through the vent 33. Dust particles in the air are filtered and retained inside the dust collection box 13, thus achieving dust suppression and reducing the environmental impact of dust during cleaning. The dust collection box 13 has symmetrically hinged guide plates 11 on both sides. A slider 31 is slidably installed in the groove 30 on the side wall of the guide plate 11. The slider 31 is connected to the outer wall of the rotating plate 5 via a fixed rod 32. When the rotating plate 5 reciprocates, the fixed rod 32 drives the slider 31 to slide in the groove 30, causing the guide plate 11 to rotate around the hinge point, adjusting its angle. The guide plate 11 can guide debris generated during cleaning in a specific direction, better drawing it into the dust collection box 13, preventing debris from splashing everywhere, improving cleaning efficiency and the quality of the on-site environment.

[0030] Furthermore, the connecting unit 35 can be a gear set or a worm gear and worm wheel combination, which will not be described in detail here.

[0031] Please see Figures 1-3 As an embodiment of the present invention, the lifting assembly includes a driving component 15, a power rod 16 is installed at the output end of the driving component 15, a rotating rod 17 is symmetrically arranged on the base 1, one end of the rotating rod 17 is rotatably connected to the mounting block 2, and the other end of the rotating rod 17 is fixedly connected to a threaded rod 19. The mounting block 2 has a threaded groove that matches the threaded rod 19, and the threaded rod 19 and the threaded groove are connected by threads. A connecting mechanism 18 is installed on the power rod 16, and the end of the connecting mechanism 18 away from the power rod 16 is connected to the rotating rod 17.

[0032] In this embodiment, after the drive component 15 is started, its output end drives the power rod 16 to move. The power rod 16 is connected to the rotating rod 17 through the connecting mechanism 18. When the power rod 16 moves, it drives the rotating rod 17 to rotate through the connecting mechanism 18. One end of the rotating rod 17 is rotatably connected to the mounting block 2, and the threaded rod 19 at the other end is threadedly connected to the threaded groove on the mounting block 2. When the rotating rod 17 rotates, the threaded rod 19 rotates in the threaded groove. Due to the transmission effect of the thread, the mounting block 2 rises or falls relative to the base 1, thereby adjusting the height of the electric cleaning brush 7 to adapt to the cleaning needs of tunnel inverts at different heights.

[0033] Furthermore, the driving component 15 can be a stepper motor or a servo motor, etc., which will not be described in detail here.

[0034] Furthermore, the connecting mechanism 18 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0035] The working principle of this invention is as follows: Before cleaning, the height of the electric cleaning brush 7 is adjusted. The drive component 15 starts, and its output end drives the power rod 16 to move. The power rod 16 is connected to the rotating rod 17 through the connecting mechanism 18. When the power rod 16 moves, it drives the rotating rod 17 to rotate through the connecting mechanism 18. One end of the rotating rod 17 is rotatably connected to the mounting block 2, and the other end of the threaded rod 19 is threadedly connected to the threaded groove on the mounting block 2. When the rotating rod 17 rotates, the threaded rod 19 rotates in the threaded groove. Due to the transmission effect of the thread, the mounting block 2 rises or falls relative to the base 1, thereby adjusting the height of the electric cleaning brush 7 to meet the cleaning needs of tunnel arches of different heights. The dual-axis motor 37 starts, and one of its output ends drives the first drive shaft to rotate. The turntable 21 rotates accordingly, and the eccentrically mounted guide rod 23 performs circular motion. Guide rod 23 is located in the drive groove of drive plate 22, causing drive plate 22 to reciprocate linearly, which in turn drives rotating plate 5 to oscillate around rotating shaft 4 via drive rod 24; the second drive shaft 36 rotates, causing driven shaft 14 to rotate, and stirring rod 34 installed on driven shaft 14 stirs the cleaning liquid in water storage chamber 10 to make its components evenly mixed. When cleaning liquid needs to be sprayed, suction pump is started to draw the cleaning liquid in water storage chamber 10 to nozzle 8 through connecting pipe 9 and spray it out. Nozzle 8 is on one side of electric cleaning brush 7 and is connected to mounting bracket 6 through connecting rod to ensure that the cleaning liquid spray position matches the cleaning position of electric cleaning brush 7; during cleaning, rotating plate 5 oscillates back and forth, driving electric cleaning brush 7 to wipe the surface of tunnel arch. Adjusting the telescopic length of the telescopic component 26 within the adjusting groove 25 changes the position of the mounting rod 27, adjusting the cleaning range and pressure of the electric cleaning brush 7 to adapt to tunnel inverts of varying degrees and sizes of dirt. Furthermore, the rotation of the driven shaft 14 also drives the fan blades 29 within the dust collection box 13 to rotate, creating negative pressure within the dust collection box 13. Outside air enters through the vent 33, while dust is filtered and retained inside the box, achieving dust suppression. When the rotating plate 5 swings, the fixed rod 32 drives the slider 31 to slide in the groove 30 of the guide plate 11, causing the guide plate 11 to rotate around the hinge point. This adjusts the angle, guiding debris in a specific direction and sucking it into the dust collection box 13, preventing debris from splashing and improving cleaning efficiency and the quality of the on-site environment.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
