Description

Technical Field

[0001] This utility model belongs to the field of tunnel pipeline cleaning technology, and relates to a crystal removal device for tunnel drainage pipelines, and more particularly to a crystal removal device for karst tunnel drainage pipelines. Background Technology

[0002] In karst tunnel engineering, drainage pipes play a crucial role, effectively removing accumulated water from the tunnel to ensure its structural safety and normal operation. However, due to the unique water quality in karst areas, which contains a large amount of minerals, these minerals gradually crystallize and deposit on the inner walls of the drainage pipes over long-term use. Over time, the crystallized layer thickens, severely clogging the pipes, reducing drainage capacity, and even causing the drainage system to fail.

[0003] Currently, methods for removing crystals from drainage pipes in karst tunnels are limited and have many drawbacks. Traditional manual removal methods require workers to enter the drainage pipes. However, the space inside karst tunnel drainage pipes is confined and the environment is harsh, making the operation difficult for workers, resulting in low efficiency and significant safety hazards, such as the possibility of encountering toxic or harmful gases or collapses.

[0004] In addition, some methods employ chemical agents to dissolve and crystallize the crystals. However, this method requires large quantities of chemicals, which is not only costly but may also corrode the drainage pipes, shortening their lifespan. Furthermore, the discharge of these chemicals may pollute the surrounding environment, failing to meet environmental protection requirements. To address the aforementioned problems, this technical solution proposes a crystallization removal device for karst tunnel drainage pipes. Utility Model Content

[0005] In view of this, in order to solve the problems of low efficiency, high safety hazards, high cost and environmental pollution of traditional methods for removing crystals from drainage pipes in karst tunnels, this utility model provides a crystal removal device for tunnel drainage pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crystal removal device for tunnel drainage pipes includes an assembly fixing ring I. Two arc-shaped connecting plates are symmetrically fixedly installed on one side of the assembly fixing ring I. A single assembly fixing ring II is fixedly installed on one side of each of the two arc-shaped connecting plates. Multiple displacement rods are slidably connected at equal intervals through the inner walls of the assembly fixing ring I and the inner walls of the assembly fixing ring II. A driving mechanism is installed at one end of each displacement rod. The driving mechanism is in close contact with the inner wall of the drainage pipe being cleaned, enabling the entire device to move within the drainage pipe during operation. The removal device also includes:

[0008] An adjustment mechanism is installed on the other side of the assembly fixing ring I. One side of the adjustment mechanism passes through the assembly fixing ring I and extends into the assembly fixing ring II. The adjustment mechanism is driven by multiple displacement rods and can drive the multiple displacement rods to move, so that the drive mechanism keeps in contact with the inner wall of the drainage pipe.

[0009] The cleaning mechanism is installed on one side of the assembly fixing ring I and assembly fixing ring II that are close to each other. The cleaning mechanism is connected to two arc connecting plates and can rotate, thereby scraping off the crystals present in the drainage pipe.

[0010] Furthermore, the drive mechanism includes a device mounting bracket fixedly installed at one end of the displacement rod, a drive motor II fixedly installed on one side of the device mounting bracket, the output shaft of the drive motor II extending into the device mounting bracket and a rolling wheel fixedly installed thereon, and one side of the rolling wheel extending to the outside of the device mounting bracket.

[0011] Beneficial effects: The drive displacement rod moves to make the rolling wheel come into close contact with the inner wall of the drainage pipe. Then, by starting the drive motor II, the rolling wheel can be driven to rotate, so that the whole device can keep moving inside the drainage pipe, so as to drive the cleaning mechanism to move and clean the crystals in different locations inside the drainage pipe.

[0012] Furthermore, the adjustment mechanism includes a structural support frame fixedly installed on the other side of the assembly fixing ring I. A drive motor I is fixedly installed on one side of the structural support frame. The output shaft of the drive motor I extends into the structural support frame and is connected to a transmission assembly. The transmission assembly passes through the assembly fixing ring I and the assembly fixing ring II respectively and is connected to the inner wall of the assembly fixing ring I and the inner wall of the assembly fixing ring II respectively. The transmission assembly is in transmission cooperation with multiple displacement moving rods respectively.

[0013] Beneficial effects: By starting the drive motor I to drive the transmission component to move, multiple displacement rods can be moved simultaneously, thereby adjusting the position of the rolling wheel and making the rolling wheel fit tightly against the inner wall of the drainage pipe.

[0014] Furthermore, the transmission assembly includes a power transmission shaft fixedly mounted on the output shaft of drive motor I. The power transmission shaft passes through assembly fixing ring I and assembly fixing ring II respectively. Two transmission rotating disks are symmetrically fixedly sleeved on the power transmission shaft. The two transmission rotating disks are located inside assembly fixing ring I and assembly fixing ring II respectively and are rotatably connected to the inner walls of assembly fixing ring I and assembly fixing ring II respectively. Multiple arc-shaped through holes are equally spaced on the transmission rotating disks. Limiting stop shafts are fixedly mounted on the displacement moving rod. The limiting stop shafts pass through the corresponding arc-shaped through holes and are in transmission cooperation with the inner walls of the arc-shaped through holes.

[0015] Beneficial effects: When the power transmission shaft rotates with the output shaft of drive motor I, it can drive the two transmission rotating disks to rotate. At this time, under the transmission action of the limit stop shaft that is in transmission cooperation with the arc-shaped through hole, it can drive the displacement rod to rotate, thereby moving the rolling wheel to a position that is in close contact with the inner wall of the drainage pipe.

[0016] Furthermore, the cleaning mechanism includes two connecting and fixing rings, which are respectively fixedly installed on the side of assembly fixing ring I and assembly fixing ring II that are close to each other. The side of the two connecting and fixing rings that are close to each other is rotatably connected to the same rotating tube. The side of the two arc connecting plates that are close to each other is fixedly installed with the same bearing plate. A power component is installed on the top of the bearing plate. The power component is connected to the inner wall of the rotating tube and can drive the rotating tube to rotate. Multiple scraper assemblies are installed at equal intervals on the rotating tube. The scraper assemblies are in contact with the inner wall of the drainage pipe.

[0017] Beneficial effects: By activating the power unit, the rotating tube can be driven to rotate, which in turn drives multiple scraper components to perform a circular motion. The scraper components scrape the inner wall of the drainage pipe, thereby scraping off the crystals attached to the inner wall of the drainage pipe and cleaning the drainage pipe.

[0018] Furthermore, the power assembly includes a drive motor III fixedly mounted on the top of the support plate, a transmission gear fixedly mounted on the output shaft of the drive motor III, and a meshing gear ring fixedly mounted on the inner wall of the rotating tube, with the transmission gear meshing with the meshing gear ring.

[0019] Beneficial effects: By starting the drive motor III, the transmission gear is driven to rotate. Under the meshing transmission action with the meshing gear ring, the rotating tube can be driven to rotate, thereby driving multiple scraper assemblies to perform circular motion, which can clean the crystals attached to the inner wall of the drainage pipe.

[0020] Furthermore, a sliding guide ring I is fixedly installed inside the connecting fixed ring, and a sliding guide ring II is rotatably connected inside the sliding guide ring I. One side of the sliding guide ring II extends to the outside of the connecting fixed ring and is fixedly connected to the side corresponding to the rotating tube.

[0021] Beneficial effects: By utilizing the rotational connection between sliding guide ring I and sliding guide ring II, the rotating tube can be rotated and supported, enabling it to maintain a stable rotational state.

[0022] Furthermore, the scraper assembly includes two protective covers fixedly mounted on the rotating tube. A conical positioning pin is inserted into each protective cover, with one end extending to the outside of the protective cover and fixedly mounted with a helical drive rod. The same equipment mounting plate is fitted onto both helical drive rods. Two fastening nuts, respectively fitted onto the two helical drive rods, are symmetrically rotatably connected to the equipment mounting plate. The fastening nuts are threadedly connected to the corresponding helical drive rods. Two structural support covers are symmetrically fixedly mounted on the equipment mounting plate, with one end of each helical drive rod extending into the corresponding structural support cover. The same cleaning scraper is fixedly mounted on one side of both structural support covers. The cleaning scraper is used to scrape off crystals adhering to the inner wall of the drainage pipe.

[0023] Beneficial effects: Inserting the conical positioning pin into the corresponding protective cover allows the cleaning scraper to be connected to the rotating tube via the insertion and locking mechanism between the protective cover and the conical positioning pin. By rotating the fastening nut and engaging the threaded drive of the corresponding screw transmission rod, the position of the equipment mounting plate can be adjusted. When the equipment mounting plate moves, the two structural support covers drive the cleaning scraper to move, keeping it in contact with the inner wall of the drainage pipe. Then, when the rotating tube rotates, it drives the cleaning scraper to make a circular motion, which can scrape off the crystals adhering to the inner wall of the drainage pipe, thereby cleaning the drainage pipe.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The tunnel drainage pipe crystal removal device disclosed in this utility model drives the displacement rod to move so that the rolling wheel is in close contact with the inner wall of the drainage pipe. Then, by starting the drive motor II, the rolling wheel can be driven to rotate, so that the whole device can keep moving inside the drainage pipe, so as to drive the cleaning mechanism to move and clean the crystals in different positions inside the drainage pipe.

[0026] 2. The tunnel drainage pipe crystallization removal device disclosed in this utility model drives the transmission component to move by starting the drive motor I, thereby simultaneously driving multiple displacement rods to move, thereby adjusting the position of the rolling wheel so that the rolling wheel fits tightly against the inner wall of the drainage pipe.

[0027] 3. The tunnel drainage pipe crystal removal device disclosed in this utility model can drive the rotating pipe to rotate when the power component is started, thereby driving multiple scraper components to perform circular motion, so that the scraper components scrape the inner wall of the drainage pipe, thereby scraping off the crystals attached to the inner wall of the drainage pipe, thus cleaning the drainage pipe.

[0028] 4. The tunnel drainage pipe crystal removal device disclosed in this utility model can clean narrow drainage pipes, reduce safety hazards, and improve work efficiency; it does not require a large amount of chemical agents, thus reducing costs, preventing pipe corrosion, extending service life, and reducing environmental pollution; it can move stably and be precisely adjusted so that the cleaning scraper can closely adhere to the pipe wall, effectively scrape off crystals, and ensure unobstructed drainage.

Detailed Implementation

[0039] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0040] like Figures 1-2 The tunnel drainage pipe crystal removal device shown comprises an assembly fixing ring I1, an assembly fixing ring II3, an arc connecting plate 2, a displacement moving rod 9, a drive mechanism, an adjustment mechanism, and a cleaning mechanism.

[0041] Assembly fixing ring I1 and assembly fixing ring II3 are connected by two symmetrically fixed arc connecting plates 2. Multiple displacement rods 9 are slidably connected through the inner walls of assembly fixing ring I1 and assembly fixing ring II3 at equal intervals.

[0042] like Figure 7 As shown, the drive mechanism is installed at one end of the displacement rod 9. Specifically, an equipment mounting bracket 11 is fixedly installed at one end of each displacement rod 9. A drive motor II 12 is fixedly installed on one side of the equipment mounting bracket 11. The output shaft of the drive motor II 12 extends into the equipment mounting bracket 11 and a rolling wheel 13 is fixedly installed thereon. One side of the rolling wheel 13 extends to the outside of the equipment mounting bracket 11. When the drive displacement rod 9 moves to make the rolling wheel 13 come into close contact with the inner wall of the drainage pipe, the drive motor II 12 is started. Its output shaft drives the rolling wheel 13 to rotate, causing the entire device to move inside the drainage pipe and driving the cleaning mechanism to clean the crystals at different locations.

[0043] The adjustment mechanism is installed on the other side of the assembly fixing ring I1, including a structural support frame 4 fixedly installed on the other side of the assembly fixing ring I1. A drive motor I5 is fixedly installed on one side of the structural support frame 4, and the output shaft of the drive motor I5 extends into the structural support frame 4 and connects to the transmission assembly. Figure 6 As shown, the transmission assembly includes a power transmission shaft 6 fixedly mounted on the output shaft of drive motor I5. The power transmission shaft 6 passes through assembly fixing ring I1 and assembly fixing ring II3 respectively, and two transmission rotating disks 7 are symmetrically fixedly mounted on the power transmission shaft 6. The two transmission rotating disks 7 are located inside assembly fixing ring I1 and assembly fixing ring II3 respectively, and are rotatably connected to the corresponding inner walls. Multiple arc-shaped through holes 8 are equally spaced on the transmission rotating disks 7. A limiting stop shaft 10 is fixedly mounted on the displacement moving rod 9. The limiting stop shaft 10 passes through the corresponding arc-shaped through holes 8 and is in transmission engagement with the inner wall of the arc-shaped through holes 8. When drive motor I5 is started, its output shaft drives the power transmission shaft 6 to rotate, which in turn drives the two transmission rotating disks 7 to rotate. Under the transmission action of the arc-shaped through holes 8 and the limiting stop shaft 10, the displacement moving rod 9 is moved, adjusting the position of the rolling wheel 13 so that it fits tightly against the inner wall of the drainage pipe.

[0044] like Figure 5 As shown, the cleaning mechanism is installed on the side of the assembly fixing ring I1 and assembly fixing ring II3 close to each other, and is connected to two arc-shaped connecting plates 2. The cleaning mechanism includes two connecting fixing rings 14 respectively fixedly installed on the side of the assembly fixing ring I1 and assembly fixing ring II3 close to each other, and the two connecting fixing rings 14 are rotatably connected to the same rotating tube 15 on the side of the assembly fixing ring I1 and assembly fixing ring II3 close to each other. The two arc-shaped connecting plates 2 are fixedly installed on the same bearing plate 18 on the side of the assembly fixing ring I1 and assembly fixing ring II3 close to each other, and a power assembly is installed on the top of the bearing plate 18. The power assembly includes a drive motor III 19 fixedly installed on the top of the bearing plate 18, a transmission gear 20 fixedly installed on the output shaft of the drive motor III 19, and a meshing gear ring 21 (e.g., a toothed ring) fixedly installed on the inner wall of the rotating tube 15. Figure 4 As shown, the transmission gear 20 meshes with the meshing gear ring 21. A sliding guide ring I 16 is fixedly installed inside the connecting and fixing ring 14. A sliding guide ring II 17 is rotatably connected inside the sliding guide ring I 16. One side of the sliding guide ring II 17 extends to the outside of the connecting and fixing ring 14 and is fixedly connected to the corresponding side of the rotating tube 15. The rotating connection between the sliding guide ring I 16 and the sliding guide ring II 17 provides rotational support for the rotating tube 15, keeping it in a stable rotational state.

[0045] like Figure 3As shown, multiple scraper assemblies are installed at equal intervals on the rotating tube 15. Each scraper assembly includes two protective covers 22 fixedly mounted on the rotating tube 15. Conical positioning pins 23 are inserted into the protective covers 22, with one end of each pin extending to the outside of the protective cover 22 and fixedly mounted on a spiral drive rod 24. The same equipment mounting plate 28 is fitted onto the two spiral drive rods 24. Two fastening nuts 27, respectively fitted onto the two spiral drive rods 24, are symmetrically rotatably connected to the equipment mounting plate 28. The fastening nuts 27 are threadedly connected to the corresponding spiral drive rods 24. Two structural support covers 25 are symmetrically fixedly mounted on the equipment mounting plate 28, with one end of each spiral drive rod 24 extending into the corresponding structural support cover 25. The same cleaning scraper 26 is fixedly mounted on one side of each structural support cover 25. Insert the conical positioning pin 23 into the corresponding protective cover 22. The cleaning scraper 26 is connected to the rotating tube 15 via the insertion and locking of the protective cover 22 and the conical positioning pin 23. By rotating the fastening nut 27, the position of the equipment mounting plate 28 is adjusted under the threaded transmission action of the corresponding screw drive rod 24. When the equipment mounting plate 28 moves, it drives the cleaning scraper 26 to move through the two structural support covers 25, keeping the cleaning scraper 26 in contact with the inner wall of the drainage pipe. Start the drive motor III 19 to drive the transmission gear 20 to rotate. Under the meshing transmission action with the meshing gear ring 21, the rotating tube 15 rotates, which in turn drives the cleaning scraper 26 to perform a circular motion, scraping off the crystals adhering to the inner wall of the drainage pipe, thus cleaning the drainage pipe.

[0046] When using the tunnel drainage pipe crystallization removal device, the cleaning scraper 26 is inserted into the corresponding protective cover 22 through the two corresponding conical positioning pins 23 to position and install the cleaning scraper 26. Then, the fastening nuts 27 are turned and tightened to adjust the position of the equipment mounting plate 28 under the threaded transmission action of the screw drive rod 24, so that after the whole device is moved into the drainage pipe to be cleaned, the cleaning scraper 26 can contact the inner wall of the drainage pipe. Then, the device is placed in the drainage pipe to be cleaned.

[0047] The drive motor I5 in the adjustment mechanism is started, and its output shaft drives the power transmission shaft 6 to rotate. The power transmission shaft 6 causes the two transmission rotating disks 7 to rotate. The arc-shaped through hole 8 on the transmission rotating disk 7 is engaged with the limit stop shaft 10 on the displacement moving rod 9, which drives the displacement moving rod 9 to move. This causes the rolling wheel 13 installed on the equipment mounting bracket 11 at one end of the displacement moving rod 9 to fit tightly against the inner wall of the drainage pipe. Next, the drive motor II12 in the drive mechanism is started, and its output shaft drives the rolling wheel 13 to rotate, causing the entire device to move inside the drainage pipe and move the device to the position where crystals need to be cleaned. Then, the power component in the cleaning mechanism is started, and the output shaft of the drive motor III19 drives the transmission gear 20 to rotate. The transmission gear 20 meshes with the meshing gear ring 21 on the inner wall of the rotating tube 15, which drives the rotating tube 15 to rotate. When the rotating tube 15 rotates, the sliding guide ring I16 and the sliding guide ring II17 in the connecting fixing ring 14 provide rotational support for the rotating tube 15, keeping it in a stable rotational state. Rotating the rotating tube 15 causes multiple scraper assemblies installed at equal intervals on it to rotate. The cleaning scraper 26 in the scraper assembly is in contact with the inner wall of the drainage pipe, scraping off the crystals adhering to the inner wall of the drainage pipe during rotation. If the cleaning scraper 26 is not in tight contact with the inner wall of the drainage pipe, the fastening nut 27 on the equipment mounting plate 28 can be rotated. Under the threaded drive of the screw drive rod 24, the equipment mounting plate 28 is moved, which drives the cleaning scraper 26 to move through the structural support cover 25, so that the cleaning scraper 26 is in tight contact with the inner wall of the drainage pipe, thereby scraping off the crystals on the inner wall of the drainage pipe and completing the cleaning work of the drainage pipe.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
