Description

Technical Field

[0001] The present invention relates to the technical field related to pipeline crystallization cleaning, and in particular to a device for dredging and sucking silt from a tunnel drainage pipe that is self-adaptive to crystallization blockage. Background Art

[0002] Tunnel drainage pipes in limestone areas can perform well in the initial stage of tunnel operation. However, as the operating years increase year by year, tunnels in limestone areas are affected by the hydrodynamic effects of karst water or dissolved liquids, and white crystals gradually accumulate along the inner and outer walls of the tunnel drainage pipes, greatly reducing the drainage efficiency and drainage effect of the limestone tunnel, and even eventually leading to complete failure of the drainage pipes, affecting the safety and stability of the tunnel lining structure and the surrounding rock behind the lining.

[0003] At present, a mechanical vehicle is used to enter the interior of the pipeline, and then a rotating scraper is used to scrape and clean the crystals on the inner wall of the pipeline. The crystals and sludge that fall down from the cleaning and scraping are discharged collectively through the mechanical vehicle. First, the scraper cannot adapt to pipelines of different inner diameters, resulting in the inability to offset the inner wall of the pipeline, which reduces the cleaning effect of the crystals. In addition, when the scraper is rotating and scraping the crystals on the inner wall of the pipeline, the sewage at the bottom of the pipeline and the crystals splashed down by the scraping are also brought to the inner wall of the pipeline again, resulting in the scraper also splashing and contaminating the inner wall of the pipeline when scraping the crystals down. This will reduce the cleaning effect of the scraper on the inner wall of the pipeline, and the cleaned sewage will gather at the inner bottom along the pipe wall again, reducing the cleaning effect on the bottom of the pipeline, resulting in crystals remaining at the bottom of the pipeline again.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the servo motor in the motion fitting component drives the moving block on the fixed screw to realize reciprocating motion under the limit of the motion rod. The expansion plate realizes stable lifting motion under the action of the T-shaped slide groove and the T-shaped slider. The expansion plate will drive the walking wheel and the auxiliary wheel to fit and support the inner wall of the pipe with different inner diameters. The arc scraper and the movable scraper in the scraping cleaning component are staggered to realize preliminary cleaning and fine cleaning of the inner wall of the pipe, while reducing the secondary pollution of the inner wall of the pipe by sewage. The residue push component is used to clean the sludge and crystals that are gathered again, thereby improving the cleaning effect inside the pipe.

[0018] 2. In the present invention, the arc scraper connected to the arc swing arm on the outer periphery of the rotating column in the scraping cleaning component performs preliminary rotational scraping on the crystals on the inner wall of the pipe, scraping off the larger and easier-to-clean crystals. The drainage holes on the arc scraper will not drive the sewage at the bottom of the pipe to the surrounding inner wall of the pipe during the rotational movement. The second hinge is used in conjunction with the hinge rod to adjust the angle of the arc scraper, so that the arc scraper can adapt to pipes of different inner diameters for close cleaning, thereby improving the cleaning ability.

[0019] 3. In the present invention, an acidic dissolving liquid is sprayed around the pipeline through the connecting seat, the arc-shaped spray seat and the spray head to dissolve the crystals that are difficult to clean. The inner wall of the pipeline is finely rotated and cleaned by the movable scraper in the scraping cleaning assembly. The movable scraper is vertically fitted to the inner wall of the pipeline to improve the thorough cleaning of the crystals on the inner wall of the pipeline. The rotating disk, the arc-shaped rotating groove and the fixed rotating shaft are used to lift and lower the movable rod in the fixed support plate, and the distance between the movable scraper and the pipelines with different inner diameters is adjusted synchronously, so that the movable scraper fits closely to the inside of the pipeline for cleaning.

[0020] 4. In the present invention, splash prevention is achieved by rotating the waterproof flip plate on the side of the movable scraper in the scraping cleaning assembly. When the movable scraper and the sewage at the bottom of the pipe are rotated, the sewage rotates the waterproof flip plate, so that the sewage driven by the rotation will not adhere to the inner wall of the pipe along with the movable scraper. The waterproof groove of the movable scraper can also reduce the contact with the sewage at the bottom of the pipe while achieving cleaning crystals, thereby improving the cleaning effect on the inner wall of the pipe.

[0021] 5. In the present invention, the stepping motor in the rotating column of the fitting assembly drives the movable screw to rotate, and the movable block on the movable bolt rod realizes reciprocating motion under the limitation of the hinge rod and the movable groove. During the rotation process, the rotating disk drives the fixed rotating shaft to expand or retract through the arc-shaped rotating groove, so that the movable scraper and the arc scraper can fit the inner wall of the pipe and move, thereby improving the cleaning effect of the crystals on the inner wall of the pipe.

[0022] 6. In the present invention, the connecting block and connecting rod of the residue pushing assembly drive the fan-shaped scraper to push the sewage at the bottom of the pipe, push the collected sewage to the position of the sludge suction pipe, and the residual sewage is discharged again through the sludge suction pump and the sludge suction pipe.

The limiting base plate 50 is provided with a T-shaped groove 51 on the side away from the spherical front cover 11. A T-shaped slider 52 is slidably connected in the T-shaped groove 51. The T-shaped slider 52 is fixedly installed with a stretching plate 53. The cleaning shell 10 is provided with three groups of sizes that match the stretching plate 53. The support hole 54, and the support plates 53 are all movable in the support holes 54. A servo motor 43 is fixedly installed at one end of the fixed column 40 close to the spherical front cover 11, and the output end of the servo motor 43 is connected to the moving block 45 through a fixed screw 44. The moving block 45 is surrounded by a moving rod 46. The moving rod 46 passes through the fixed column 40 and is installed on the inner side of the moving ring 41. The support plate 53 and the moving ring 41 are movably connected with the support rod 42 through a first hinge 47. The support plate 53 is installed with a walking seat 55 at both ends of the side away from the fixed column 40. A walking wheel 56 is movably provided on the walking seat 55 close to the spherical front cover 11, and a driving box 57 for driving the walking wheel 56 to move is provided on the walking seat 55. An auxiliary wheel 58 that fits the inner wall of the pipe is movably provided on the walking seat 55 away from the spherical front cover 11.

[0038] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The driving box 57 on the front traveling seat 55 drives the traveling wheel 56 to travel around the inner wall of the pipe, and the auxiliary wheel 58 on the rear traveling seat 55 cooperates with the traveling wheel 56 to drive the cleaning shell 10 to travel inside the pipe. When cleaning pipes with different inner diameters, the moving block 45 on the fixed screw 44 is driven by the servo motor 43 to realize reciprocating motion under the limit of the moving rod 46. The moving block 45 drives the moving ring 41 outside the fixed column 40 to move synchronously through the moving rod 46. The moving ring 41 is connected to the limiting bottom plate 50 through the first hinge 47 and the expansion rod 42. The expansion plate 53 is lifted and pushed. When the moving ring 41 moves toward one end of the spherical front cover 11, the expansion plate 53 on the limiting base plate 50 is driven to move downward through the first hinge 47 and the expansion rod 42. When the moving ring 41 moves away from the spherical front cover 11, the expansion plate 53 on the limiting base plate 50 is driven to move downward through the first hinge 47 and the expansion rod 42. The expansion plate 53 realizes stable lifting and lowering movement under the action of the T-shaped slide groove 51 and the T-shaped slider 52. The expansion plate 53 will drive the walking wheel 56 and the auxiliary wheel 58 to fit and support the inner wall of the pipe with different inner diameters.

[0039] See Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10, a scraping cleaning component is provided on the outside of the rotating column 20 for cleaning the inner wall of the pipe. The arc-shaped scraper 21 in the scraping cleaning component performs preliminary cleaning on the crystals on the inner wall of the pipe. The movable scraper 22 in the scraping cleaning component is used to fit the inner wall of the pipe for fine cleaning. The scraping cleaning component also includes an arc-shaped swing arm 23 and a fixed support plate 24. The rotating column 20 is evenly provided with three groups of arc-shaped swing arms 23 on the outer periphery of the end away from the spherical front cover 11. The arc-shaped scraper 21 is fixedly installed at the top end of the arc-shaped swing arm 23. The rotating column 20 is evenly provided with three groups of fixed support plates 24 on the outer periphery of the end close to the spherical front cover 11. The interior of the fixed support plate 24 is connected to a movable rod 70 through a limiting strip 71. The movable scraper 22 is fixedly installed at the top end of the movable rod 70, and the arc-shaped scraper 21 and the movable scraper 22 both move in fit with the inner wall of the pipe. A rotating motor 73 is fixedly installed inside the spherical front cover 11, and the output end of the rotating motor 73 is connected to the first gear 74 through a rotating shaft. A second gear 75 is fixedly installed at one end of the rotating column 20 located inside the spherical front cover 11, and the second gear 75 is movably engaged with the first gear 74. A plurality of drainage holes 25 are evenly provided on the arc scraper 21, and waterproof grooves 26 are provided on both sides of the movable scraper 22. The movable scraper 22 is movably connected to a waterproof flip plate 27 in the waterproof groove 26 through a rotating shaft. A plurality of drainage grooves 28 are evenly provided on the top of the movable scraper 22. The arc swing arm 23 and the fixed support plate 24 are staggered on the outside of the rotating column 20. A plurality of arc spray seats 16 with spray heads 15 are evenly installed around the top of the spherical front cover 11, and a connecting seat 17 connected to the arc spray seat 16 is installed inside the spherical front cover 11.

[0040] See Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10The rotary motor 73 in the spherical front cover 11 drives the first gear 74 to rotate, and the first gear 74 engages the second gear 75 to drive the rotating column 20 to rotate. The arc scraper 21 connected to the arc swing arm 23 on the outer periphery of the rotating column 20 performs preliminary rotational scraping on the crystals on the inner wall of the pipe, and scrapes off the larger and easier-to-clean crystals. The drainage holes 25 on the arc scraper 21 will not drive the sewage at the bottom of the pipe to the surrounding inner wall of the pipe during the rotational movement. After the preliminary cleaning of the inner wall of the pipe, the acidic dissolving liquid is sprayed around the pipe through the connecting seat 17, the arc spray seat 16 and the spray head 15 to dissolve the difficult-to-clean crystals, and then the inner wall of the pipe is finely cleaned by the movable scraper 22. The movable scraper 22 is vertically fitted with the inner wall of the pipe to improve the thorough cleaning of the crystals on the inner wall of the pipe. The sludge suction pipe 13 is used to cooperate with the sludge suction pump 12 and the discharge pipe 14 to discharge the sewage and the cleaned crystals inside the pipe. The waterproof flip plate 27 rotating on the side of the movable scraper 22 is used to achieve a certain degree of splash-proof effect. When the movable scraper 22 and the sewage at the bottom of the pipe are rotated, the sewage rotates the waterproof flip plate 27, so that the sewage driven by the rotation will not adhere to the inner wall of the pipe with the movable scraper 22. The waterproof groove 26 of the movable scraper 22 can also reduce the contact with the sewage at the bottom of the pipe while cleaning the crystals, effectively preventing the sewage at the bottom of the pipe from polluting the surrounding area of the pipe.

[0041] See Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 , an adaptive fitting component is provided inside the rotating column 20, and the adaptive fitting component is used to fit the movable scraper 22 and the arc scraper 21 to the inner wall of the pipe. A sludge suction pump 12 is provided inside the spherical front cover 11, and the input end of the sludge suction pump 12 is connected to the sludge suction pipe 13 located at the bottom of the spherical front cover 11, and the output end of the sludge suction pump 12 is fixedly installed with a discharge pipe 14. The adaptive fitting component includes a movable screw 61 and a rotating disk 62 that are movable inside the rotating column 20. A stepping motor 60 is fixedly installed at one end of the rotating column 20 near the rotating motor 73, and the movable screw 61 is fixedly mounted on the stepping motor 6 0 output end, the movable screw 61 is threadedly connected to the movable block 63 at the end away from the rotating motor 73, and the movable block 63 and the arc-shaped swing arm 23 are movably connected with a hinged rod 65 through a second hinge 64, and the hinged rod 65 movably passes through the movable groove 66 provided on the rotating column 20, and the movable screw 61 is fixedly installed with a rotating disk 62 at the end close to the rotating motor 73, and the rotating disk 62 is provided with an arc-shaped rotating groove 67, and the bottom of the movable rod 70 is fixedly installed with a fixed rotating shaft 72 that matches the size of the arc-shaped rotating groove 67, and the fixed rotating shaft 72 moves in the arc-shaped rotating groove 67.

[0042] See Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The stepping motor 60 in the rotating column 20 drives the movable screw 61 to rotate, and the movable block 63 on the movable bolt rod realizes reciprocating motion under the limit of the hinge rod 65 and the movable groove 66. During the movement, the movable block 63 adjusts the angle of the arc-shaped swing arm 23 through the second hinge 64 and the hinge rod 65, so that the arc-shaped scraper 21 at the top of the arc-shaped swing arm 23 fits the inner wall of the pipe with different inner diameters. The movable screw 61 synchronously drives the rotating disk 62 to rotate. During the rotation process, the rotating disk 62 drives the fixed rotating shaft 72 to expand or retract through the arc rotating groove 67. When the fixed shaft 72 moves, the movable rod 70 in the fixed support plate 24 moves downward, and the movable rod 70 simultaneously drives the movable scraper 22 at the top to move downward. Similarly, when the fixed shaft 72 moves, the movable rod 70 in the fixed support plate 24 moves upward, and the movable rod 70 drives the movable scraper 22 at the top to move upward. In this way, when the angle of the arc-shaped swing arm 23 is adjusted, the distance of the movable scraper 22 can also be adjusted, so that the movable scraper 22 and the arc-shaped scraper 21 can move in contact with the inner wall of the pipe, thereby improving the cleaning effect of the crystals on the inner wall of the pipe.

[0043] See Figure 1 、 Figure 5 、 Figure 11 and Figure 12 , a residue pushing assembly is provided at the inner bottom of the cleaning shell 10, and the fan-shaped scraper 30 in the residue pushing assembly scrapes the residue at the bottom of the pipe to the position of the sludge suction pipe 13, and the residue pushing assembly also includes a base block 80 fixedly installed at the bottom of the cleaning shell 10, and conical guide rails 81 are fixedly installed on the upper and lower sides of the base block 80, and the conical guide rails 81 are connected with side plates 85 through connecting blocks 82.

[0044] See Figure 1 、 Figure 5 、 Figure 11 and Figure 12The side plate 85 is connected to the side frame 32 through the limiting groove 31, and the side frame 32 is movably provided with a supporting shaft 33. The driving gear 84 is fixedly installed on the supporting shaft 33. The supporting shaft 33 is installed with a first bevel gear 34 in the side frame 32. The top of the side frame 32 is installed with a first motor 35. The output end of the first motor 35 is connected to the second bevel gear 36 located in the side frame 32 through a shaft, and the second bevel gear 36 is movably engaged with the first bevel gear 34. The first motor 35 drives the second bevel gear 36 to rotate, and the second bevel gear 36 engages with the first bevel gear 34 to drive the supporting shaft 33 to rotate, and the supporting shaft 33 then drives the driving gear 8 The driving gear 84 rotates outside the base column 83 and moves back and forth while rotating outside the base column 83, driving the side plate 85 and the side frame 32 to move horizontally. The fan-shaped scraper 30 under the side frame 32 pushes the sewage collected at the bottom. When the driving gear 84 moves on the side of the top of the base column 83, the side frame 32 rises to the top position of the side plate 85, and the fan-shaped scraper 30 is raised. The fan-shaped scraper 30 then returns to its original position on the return stroke. A connecting block 37 is fixedly installed at the end of the side frame 32 away from the base block 80. A connecting rod 38 is fixedly installed at the bottom of the connecting block 37. The fan-shaped scraper 30 is installed at the bottom end of the connecting rod 38.

[0045] See Figure 5 、 Figure 11 and Figure 12 When the driving gear 84 flips over and moves to the top of the base column 83, the fan-shaped scraper 30 is disengaged from the bottom of the pipe, driving the fan-shaped scraper 30 to return and reset.

[0046] Working principle: The walking wheels 56 and auxiliary wheels 58 of the walking seat 55 are fitted with the inner wall of the pipe, and the driving box 57 on the front walking seat 55 drives the walking wheels 56 to walk around the inner wall of the pipe. The auxiliary wheels 58 on the rear walking seat 55 cooperate with the walking wheels 56 to drive the cleaning shell 10 to walk inside the pipe. When cleaning pipes with different inner diameters, the servo motor 43 drives the moving block 45 on the fixed screw 44 to realize reciprocating motion under the limit of the moving rod 46. The moving block 45 drives the moving ring 41 outside the fixed column 40 to move synchronously through the moving rod 46. The moving ring 41 is connected to the first hinge. The component 47 and the expansion rod 42 push the expansion plate 53 on the limiting base plate 50 to rise and fall. When the moving ring 41 moves toward one end of the spherical front cover 11, the expansion plate 53 on the limiting base plate 50 is driven to move downward through the first hinge component 47 and the expansion rod 42. When the moving ring 41 moves away from the spherical front cover 11, the expansion plate 53 on the limiting base plate 50 is driven to move downward through the first hinge component 47 and the expansion rod 42. The expansion plate 53 realizes stable lifting and lowering movement under the action of the T-shaped slide groove 51 and the T-shaped slider 52. The expansion plate 53 will drive the walking wheel 56 and the auxiliary wheel 58 to fit and support the inner wall of the pipe with different inner diameters.

[0047] When the cleaning shell 10 and the spherical front cover 11 enter the interior of the pipe, the first gear 74 is driven to rotate by the rotating motor 73 in the spherical front cover 11, and the first gear 74 engages with the second gear 75 to drive the rotating column 20 to rotate. The arc scraper 21 connected to the arc-shaped swing arm 23 on the outer periphery of the rotating column 20 performs a preliminary rotational scraping on the crystals on the inner wall of the pipe, scraping off the larger and easier-to-clean crystals. The drainage holes 25 on the arc scraper 21 will not drive the dirt at the bottom of the pipe during the rotation. The water is moved around the inner wall of the pipe. After the inner wall of the pipe is preliminarily cleaned, the acidic dissolving liquid is sprayed around the pipe through the connecting seat 17, the arc-shaped spray seat 16 and the spray head 15 to dissolve the crystals that are difficult to clean. Then, the inner wall of the pipe is finely rotated and cleaned by the movable scraper 22. The movable scraper 22 is vertically attached to the inner wall of the pipe to improve the thorough cleaning of the crystals on the inner wall of the pipe. The sewage and cleaned crystals inside the pipe are discharged by the sludge suction pipe 13, the sludge suction pump 12 and the discharge pipe 14.

[0048] In order to adapt to the crystal cleaning of pipes with different inner diameters, the stepping motor 60 in the rotating column 20 drives the movable screw 61 to rotate, and the movable block 63 on the movable bolt rod realizes reciprocating motion under the limit of the hinge rod 65 and the movable groove 66. During the movement, the movable block 63 adjusts the angle of the arc-shaped swing arm 23 through the second hinge 64 and the hinge rod 65, so that the arc-shaped scraper 21 at the top of the arc-shaped swing arm 23 fits the inner wall of pipes with different inner diameters. The movable screw 61 synchronously drives the rotating disk 62 to rotate. During the rotation process, the rotating disk 62 drives the fixed rotating shaft 72 to expand or retract through the arc rotating groove 67. When the fixed rotating shaft 72 retracts, it drives the movable rod 70 in the fixed support plate 24 to move downward, and the movable rod 70 synchronously drives the movable scraper 22 at the top to move downward. Similarly, when the fixed rotating shaft 72 expands, When the movable rod 70 in the fixed support plate 24 is driven to move upward, the movable rod 70 drives the top movable scraper 22 to move upward. In this way, when the angle of the arc-shaped swing arm 23 is adjusted, the distance of the movable scraper 22 can also be adjusted, so that the movable scraper 22 and the arc-shaped scraper 21 can move in conjunction with the inner wall of the pipe, thereby improving the cleaning effect of the crystals on the inner wall of the pipe. After the movable scraper 22 rotates to the bottom position of the pipe, a certain degree of splash-proof effect is achieved through the waterproof flip plate 27 rotating on the side of the movable scraper 22. When the movable scraper 22 and the sewage at the bottom of the pipe are rotated and driven, the sewage rotates the waterproof flip plate 27, so that the sewage driven by the rotation will not adhere to the inner wall of the pipe with the movable scraper 22. The waterproof groove 26 of the movable scraper 22 can also reduce the contact with the sewage at the bottom of the pipe while cleaning the crystals, effectively preventing the sewage at the bottom of the pipe from polluting the surrounding area of the pipe.

[0049] After the silt suction pump 12 discharges the sewage at the bottom of the pipe and the crystals scraped off, the movable scraper 22 and the curved scraper 21 will carry the sewage at the bottom of the pipe to the surrounding areas of the inner wall of the pipe in the process of cleaning the crystals. At this time, the sewage adhering to the surrounding areas of the pipe will be re-collected to the bottom of the pipe under the action of gravity. At this time, the sewage collected at the bottom of the pipe can be pushed to the bottom position of the silt suction pipe 13 by the fan-shaped scraper 30, and the sewage remaining at the bottom will be discharged again, thereby improving the cleaning effect of the inner wall of the pipe. Specifically, the second bevel gear 36 is driven to rotate by the first motor 35 on the side frame 32, and the second bevel gear 36 engages with the first bevel gear 34 to drive the support shaft 33 to rotate. The support shaft 33 will drive the driving gear 84 to mesh with the base column 83. When the driving gear 84 rotates on one side of the bottom of the base column 83, the tooth groove of the driving gear 84 will move on the outer periphery of the base column 83. At this time, the driving gear 84 moves along the bottom side of the base column 83. When the driving gear 84 moves to the top of the base column 83, the fan-shaped scraper 30 is disengaged from the bottom of the pipe, driving the fan-shaped scraper 30 to return to the bottom of the pipe and reset to wait for the next centralized cleaning of the sewage at the bottom of the pipe.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
