Detailed Implementation
[0027] To further illustrate the technical solution of the present invention, the present invention will be further described below through embodiments.
[0028] like Figures 1-9As shown, this invention provides an underground sewage pipe blockage removal device, comprising a frame 7, on which a walking mechanism 3 is installed. The walking mechanism 3 is used to drive the frame 7 to move inside the sewage pipe. A control box 11 is also installed inside the frame 7. The control box 11 contains a controller and a lithium battery for controlling all electrical components on the device. A drive shaft 12 is also rotatably mounted on the frame 7. One end of the drive shaft 12 is fixedly connected to a turntable 1. The turntable 1 has a second sliding groove 51 and a first sliding groove 42 arranged perpendicularly to each other. The second sliding groove 51 and the first sliding groove 42 are not in the same vertical plane. A second slider 52 is slidably mounted in the second sliding groove 51. A pusher head 5 is rotatably mounted on the second slider 52. The pusher head is a spiral blade pusher structure. A first slider 41 is slidably mounted in the first sliding groove 42. A cutter 4 is fixedly connected to the first slider 41. The turntable 1 is also equipped with an adjustment and power mechanism 9. The adjustment and power mechanism 9 has multiple output ends, which are respectively connected to the first slider 41, the second slider 52 and the pusher head 5. The adjustment and power mechanism 9 is used to drive the first slider 41 and the second slider 52 to move and drive the pusher head 5 to rotate, thereby adjusting the distance between the pusher head 5 and the cutter 4 and the axis of the turntable 1 so as to adjust according to the height of the blockage in the sewage pipe. The frame 7 is also equipped with a rotary drive mechanism 8. One end of the rotary drive mechanism 8 is connected to the drive shaft 12. The rotary drive mechanism 8 is used to drive the drive shaft 12 to rotate, and the drive shaft 12 drives the turntable 1 to rotate, so that the turntable 1 drives the cutter 4 to cut the blockage. Then, the pusher head 5 is moved above the blockage and contacts the blockage. By adjusting the power mechanism 9, the pusher head 5 is driven to rotate. The pusher head 5 can push the blockage forward, thereby dispersing the blockage and making it easier to flush the blockage out of the sewage pipe. At the same time, by adjusting the power mechanism 9, the distance between the pusher head 5 and the bottom of the sewage pipe can be adjusted. The rotary drive mechanism 8 drives the drive shaft 12 to rotate, which can adjust the circumferential position of the pusher head 5 in the sewage pipe, so that the pusher head 5 can remove the blockage at any position in the sewage pipe, improving the cleaning effect and avoiding the obstruction of the invention by excessively high blockages.
[0029] In addition, to prevent garbage from the sewage pipe from splashing onto the regulating and power mechanism 9, a first protective cover is installed on the front end of the turntable 1, and an end cover 2 is also installed on the frame 7 to protect the internal parts of the frame 7.
[0030] The present invention provides an underground sewage pipe blockage removal device. In this embodiment, the adjustment and power mechanism 9 includes a first screw 92 and a second screw 95. The first screw 92 and the second screw 95 are both rotatably mounted on the turntable 1. The first screw 92 is threadedly connected to the first slider 41, and the second screw 95 is threadedly connected to the second slider 52. The adjustment and power mechanism 9 also includes a switchable adjustment component 94, a drive component 93, and a power component 91 mounted on the turntable 1. The two output ends of the switchable adjustment component 94 are respectively connected to the first screw 92 and the second screw 95. The switchable adjustment component 94 is used to drive the first screw 92 and the second screw 95 to rotate individually or simultaneously. The output end of the drive component 93 is connected to the push head 5. The drive component 93 is used to drive the push head 5 to rotate. Both the drive component 93 and the switchable adjustment component 94 are connected to the power component 91. The power component 91 is used to drive the drive component 93 and the switchable adjustment component 94 to rotate individually or simultaneously.
[0031] This invention provides a device for clearing blockages in underground sewage pipes. In this embodiment, the switchable adjustable component 94 includes a sixth rotating rod 947 and a fifth rotating rod 944, both rotatably mounted on a turntable 1. The output end of the power component 91 is connected to the sixth rotating rod 947 via a sixth transmission pair 948. A second electromagnetic clutch 949 connects the sixth rotating rod 947 and the second screw 95. A connection is also provided between the sixth rotating rod 947 and the fifth rotating rod 944. A first electromagnetic clutch 946 is provided. An arc-shaped plate 942 is slidably mounted on the turntable 1. The sliding axis of the arc-shaped plate 942 coincides with the axis of the turntable 1. A first bevel rack 943 and a second bevel rack 9410 are respectively mounted on the two sides of the arc-shaped plate 942. A second bevel gear 945 is fixedly mounted on the fifth rotating rod 944. The second bevel gear 945 meshes with the first bevel rack 943. A first bevel gear 941 is fixedly mounted on the first screw 92. The first bevel gear 941 meshes with the second bevel rack 9410.
[0032] Specifically, the sixth transmission pair 948 is a sprocket pair. When the power assembly 91 drives the sixth rotating rod 947 to rotate through the sixth transmission pair 948, the first electromagnetic clutch 946 is de-energized and the second electromagnetic clutch 949 is energized. Then, the sixth rotating rod 947 drives the second screw 95 to rotate through the second electromagnetic clutch 949. The second screw 95 can drive the second slider 52 to move, thereby adjusting the position of the pusher head 5. When the first electromagnetic clutch 946 is energized and the second electromagnetic clutch 949 is de-energized, the sixth rotating rod 947 drives the fifth rotating rod 944 to rotate through the first electromagnetic clutch 946. The fifth rotating rod 944 drives the first bevel rack 943 and the arc plate 942 to slide through the second bevel gear 945. The arc plate 942 drives the second bevel rack 9410 to slide. The second bevel rack 9410 drives the first bevel gear 941 and the first screw 92 to rotate. The first screw 92 drives the first slider 41 to move, thereby adjusting the position of the cutter 4.
[0033] The present invention provides an underground sewage pipe blockage removal device. In this embodiment, the drive assembly 93 includes a worm gear 932 fixedly installed at the end of the pusher head 5 and a worm 933 rotatably installed on the second slider 52. The worm 933 and the worm gear 932 mesh. A fourth rotating rod 934 is also rotatably installed on the second slider 52. A fifth transmission pair 936 is connected between the fourth rotating rod 934 and the worm 933. A second gear 935 is fixedly installed on the fourth rotating rod 934. A displacement gear 931 is also rotatably installed on the turntable 1. The second gear 935 and the displacement gear 931 mesh. The displacement gear 931 is distributed along the moving direction of the second slider 52. One end of the displacement gear 931 is connected to the output end of the power assembly 91 through a third electromagnetic clutch 937.
[0034] Specifically, the fifth transmission pair 936 is a sprocket pair, and the thickness of the displacement gear 931 is adapted to the maximum movement distance of the second slider 52 so that the displacement gear 931 and the second gear 935 are always meshed. When in operation, energizing the third electromagnetic clutch 937 causes the power assembly 91 to drive the displacement gear 931 to rotate. The displacement gear 931 then drives the second gear 935 and the fourth rotating rod 934 to rotate. The fourth rotating rod 934 drives the worm gear 933 to rotate via the fifth transmission pair 936. The worm gear 933 then drives the worm wheel 932 and the pusher head 5 to rotate. The pusher head 5 pushes the blockage in the sewage pipe forward, dispersing the blockage and making it easier to flush it out of the sewage pipe later.
[0035] In addition, the on / off state of the third electromagnetic clutch 937, the second electromagnetic clutch 949, and the first electromagnetic clutch 946 can be controlled according to the working conditions.
[0036] The present invention provides an underground sewage pipe blockage removal device. In this embodiment, the power assembly 91 includes a first rotating rod 913, a third rotating rod 917, and a second rotating rod 915. The first rotating rod 913 is rotatably mounted on a drive shaft 12, and the second rotating rod 915 is rotatably mounted on the side of a turntable 1. A universal joint 914 connects the first rotating rod 913 and the second rotating rod 915. The third rotating rod 917 is rotatably mounted inside the turntable 1. A fourth transmission pair 916 connects the second rotating rod 915 and the third rotating rod 917. A third electromagnetic clutch 937 is mounted on one end of the third rotating rod 917, and a sixth transmission pair 948 is mounted on the third rotating rod 917. The power assembly 91 also includes a first servo motor 10, which is mounted on the frame 7. The output shaft of the first servo motor 10 is connected to a fourth electromagnetic clutch 911. The fourth electromagnetic clutch 911 is rotatably mounted inside the drive shaft 12. One end of the fourth electromagnetic clutch 911 is connected to a third transmission pair 912 between itself and the first rotating rod 913.
[0037] Specifically, the fourth transmission pair 916 is a sprocket pair, and the third transmission pair 912 is a bevel gear pair. In order to enable the third electromagnetic clutch 937, the second electromagnetic clutch 949 and the first electromagnetic clutch 946 to work normally, an electric slip ring is provided between the drive shaft 12 and the frame 7 to supply power to the third electromagnetic clutch 937, the second electromagnetic clutch 949 and the first electromagnetic clutch 946.
[0038] During operation, the fourth electromagnetic clutch 911 is energized, and the first servo motor 10 drives the first rotating rod 913 to rotate through the fourth electromagnetic clutch 911 and the third transmission pair 912. The first rotating rod 913 drives the second rotating rod 915 to rotate through the universal joint 914. The second rotating rod 915 drives the third rotating rod 917 to rotate through the fourth transmission pair 916. The third rotating rod 917 drives the sixth rotating rod 947 to rotate through the sixth transmission pair 948. Then, by controlling the opening and closing of the third electromagnetic clutch 937, the second electromagnetic clutch 949 and the first electromagnetic clutch 946, the rotation of the pusher head 5, the position adjustment of the pusher head 5 and the position adjustment of the cutter 4 are realized respectively.
[0039] A second protective cover is installed on the rear end face of turntable 1. The second rotating rod 915, universal joint 914 and the first rotating rod 913 are all located inside the second protective cover for protection.
[0040] This invention controls the movement of the first slider 41 and the second slider 52, as well as the rotation of the pusher head 5, by switching on and off the first electromagnetic clutch 946, the second electromagnetic clutch 949, the third electromagnetic clutch 937, and the fourth electromagnetic clutch 911. Compared with the traditional method of mounting the motor on a rotatable turntable 1, the circuit layout of this invention is simpler (when the motor is mounted on the turntable 1, a larger current is required to start the motor, so a thicker wire is needed, and the volume of the slip ring used is also larger, because the rated current of the slip ring is usually positively correlated with its volume), reducing the possibility of circuit failures. The electromagnetic clutch requires less current, so a smaller slip ring can be used, reducing the size of the device.
[0041] The present invention provides an underground sewage pipe blockage removal device. In this embodiment, the rotary drive mechanism 8 includes a third servo motor 82 fixedly installed on the frame 7, and a second transmission pair 81 is connected between the third servo motor 82 and the drive shaft 12.
[0042] The second transmission pair 81 is a gear pair.
[0043] The present invention provides an underground sewage pipe blockage removal device. In this embodiment, the walking mechanism 3 includes an adjusting cylinder 37 installed on the frame 7. Two sets of walking components are installed on the adjusting cylinder 37. The two sets of walking components are respectively installed at both ends of the adjusting cylinder 37. Each set of walking components is provided with three walking legs. The three walking legs are evenly distributed around the adjusting cylinder 37. The outrigger includes a mounting sleeve 32 mounted on an adjusting cylinder 37. A connecting rod 310 is rotatably mounted at the end of the mounting sleeve 32. Both ends of the connecting rod 310 are fixedly connected to a walking wheel 31. A rotating shaft is rotatably mounted inside the mounting sleeve 32. One end of the rotating shaft is rotatably mounted on the frame 7. A first transmission pair 39 is connected between the other end of the rotating shaft and the connecting rod 310. The walking mechanism 3 also includes a dual-axis motor 36, which is fixedly mounted on the frame 7. Both ends of the dual-axis motor 36 are fixedly connected to a driving bevel gear 35, and one end of the rotating shaft is fixedly connected to a driven bevel gear 34. The driven bevel gear 34 and the driving bevel gear 35 mesh.
[0044] Specifically, the first transmission pair 39 is a bevel gear pair.
[0045] The dual-axis motor 36 drives two active bevel gears 35 to rotate, which in turn drives all the driven bevel gears 34 to rotate. The driven bevel gears 34 drive the rotating shaft to rotate, and the rotating shaft drives the traveling wheel 31 to rotate through the first transmission pair 39. The traveling wheel 31 rolls inside the sewage pipe, thereby enabling the device to move.
[0046] This invention provides a device for clearing blockages in underground sewage pipes. Since the diameter of underground sewage pipes varies depending on factors such as city size, drainage needs, geographical conditions, design standards, and pipe material type, even within different districts and some streets, this invention aims to adapt the device to sewage pipes of different diameters. In this embodiment, the adjusting cylinder 37 is rotatably mounted on the frame 7, and the mounting sleeve 32 is slidably mounted on the adjusting cylinder 37. The adjusting cylinder 37 has a sliding groove 311 that matches the mounting sleeve 32. The rotating shaft consists of a rotating sleeve 38 and a power source. The system consists of a rod 33, a rotating sleeve 38 rotatably mounted inside the mounting sleeve rod 32, a power rod 33 rotatably mounted on the frame 7, a rotating sleeve 38 slidably mounted on the power rod 33 and rotatably mounted synchronously with the power rod 33, a power rod 33 fixedly connected to a driven bevel gear 34, an adjusting cylinder 37 having multiple guide arc grooves 312, a guide post 313 adapted to the guide arc groove 312 fixedly connected to the side of the mounting sleeve rod 32, the guide post 313 slidably mounted inside the guide arc groove 312, and one end of the guide arc groove 312 gradually moving away from the axis of the adjusting cylinder 37; The walking mechanism 3 also includes an adjustment drive mechanism 6, which is mounted on the frame 7. One end of the adjustment drive mechanism 6 is connected to the adjustment cylinder 37. The adjustment drive mechanism 6 is used to drive the adjustment cylinder 37 to rotate, and the adjustment cylinder 37 drives the mounting sleeve 32 to move radially, thereby adjusting the distance between the walking wheels 31 and the axis of the adjustment cylinder 37, so that multiple walking wheels 31 abut against the inner wall of the sewage pipe, so that the device can move.
[0047] Specifically, the adjustment drive mechanism 6 drives the adjustment cylinder 37 to rotate, and the adjustment cylinder 37 drives the guide column 313 to move through the guide arc groove 312. The guide column 313 drives the mounting sleeve rod 32 and the traveling wheel 31 to move, so that the traveling wheel 31 moves closer to or further away from the axis of the adjustment cylinder 37. This allows the distance between the traveling wheel 31 and the middle of the frame 7 to be adjusted, so that the traveling wheel 31 contacts the inner wall of the sewage pipe. This device has a wider range of applications.
[0048] The present invention provides an underground sewage pipe blockage removal device. In this embodiment, the adjustment drive mechanism 6 includes a second servo motor 63 fixedly installed on the frame 7. The output shaft of the second servo motor 63 is fixedly installed with a first gear 62. An internal gear ring 61 is fixedly installed on the inner side wall of the adjustment cylinder 37. The internal gear ring 61 and the first gear 62 mesh.
[0049] Of course, sensors and cameras are also installed on the frame 7 to assist the present invention in detecting blockages in the sewage pipes and to assist staff in control. This is existing technology and will not be described in detail here.
[0050] Working principle: The device is placed in the sewage pipe, the second servo motor 63 is started, the second servo motor 63 drives the adjusting cylinder 37 to rotate, the adjusting cylinder 37 drives the mounting sleeve 32 and the traveling wheel 31 to move outward, so that all the traveling wheels 31 abut against the sewage pipe wall. Then the dual-axis motor 36 is started, the dual-axis motor 36 drives the traveling wheel 31 to roll, and the traveling wheel 31 drives the device forward. During normal operation, the cutter 4 contacts the inner wall of the sewage pipe, and the third servo motor 82 is started. The third servo motor 82 drives the cutter 4 to rotate through the turntable 1. The cutter 4 scrapes away the garbage on the inner wall of the sewage pipe, thus cleaning the inner wall of the sewage pipe. When encountering a high obstruction, the first servo motor 10 is activated. The first servo motor 10 drives the first screw 92 through the power component 91. The first screw 92 drives the cutter 4 to move. The position of the cutter 4 is adjusted according to the height of the obstruction so that the cutter 4 is slightly lower than the obstruction. Then, the third servo motor 82 is activated. The third servo motor 82 drives the drive shaft 12 and the turntable 1 to rotate (during the rotation of the turntable 1, the fourth electromagnetic clutch 911 is de-energized, and the third transmission pair 912 and the first rotating rod 913 follow the rotation of the turntable 1, thereby avoiding the influence of the first servo motor 10 on the rotation of the turntable 1). The turntable 1 drives the cutter 4 to cut the obstruction. After the cutter 4 rotates one revolution, the first servo motor 10 is activated again, and the position of the cutter 4 is lowered again. Then, the obstruction is cut again. This cycle is repeated to cut the obstruction layer by layer and shred it (during this process, the pusher head 5 is moved to the center of the turntable 1 to avoid the pusher head 5 hitting the obstruction and to prevent the obstruction from splashing onto the device). Then, the first servo motor 10 is started. The first servo motor 10 drives the second screw 95 through the power component 91. The second screw 95 drives the pusher head 5 to move, so that the pusher head 5 is slightly lower than the blockage. Then, the walking mechanism 3 drives the pusher head 5 forward so that the pusher head 5 is inserted into the blockage. Then, the first servo motor 10 drives the pusher head 5 to rotate through the drive component 93. The pusher head 5 can push the blockage forward. Then, the pusher head 5 is driven to descend again to push the blockage again. When the blockage is cleared, the turntable 1 can drive the pusher head 5 to deflect at a certain angle, and then push the side of the blockage again. This cycle is repeated so that all the blockages can be pushed open and laid flat at the bottom of the sewage pipe. The blockage can be transported out by the subsequent sludge removal device, or the blockage can be flushed out of the pipe by the subsequent sewage.
