[0025] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0026] Example 1

[0027] This invention discloses an intelligent online dredging robot.

[0028] Reference Figure 1 and Figure 2 A smart online sludge removal robot includes a frame 1, a conveying pipe 2 for conveying sludge, and a suction pipe 3 for pumping sludge. In this embodiment, the frame 1 includes a base plate 10 fixedly installed on the bottom wall of a sedimentation tank. A column 11 is mounted on the base plate 10, and a fixing seat 12 is mounted on the column 11. The fixing seat 12 has a cavity 13. A fixing pipe 14 and a rotating pipe 15 are respectively mounted on the fixing seat 12. One end of the fixing pipe 14 extends out of the fixing seat 12 and is used to connect to a pump, while the other end connects to a pump via a rotary joint 16. The rotating tube 15 is connected, and the base plate 10 is provided with a central tube 17. In this embodiment, the central tube 17 is a solid tube. The axis of the central tube 17, the axis of the fixed tube 14 and the axis of the rotating tube 15 are collinear. The axis of the central tube 17 is parallel to the axis of the column 11. One end of the central tube 17 is welded to the base plate 10, and the other end is connected to the rotating tube 15 through a three-way tube 18. The three-way tube 18 is rotatably connected to the central tube 17. The third outlet of the three-way tube 18 is connected to the conveying tube 2. The conveying tube 2 is arranged radially along the central tube 17.

[0029] The fixed base 12 is provided with a drive assembly 4 for driving the conveying pipe 2 to rotate. The drive assembly 4 includes a drive motor 40 set on the fixed base 12. The drive shaft of the drive motor 40 is coaxial with the driving cone wheel 41. The rotating pipe 15 is coaxial with the driven cone wheel 42. The driving cone wheel 41 and the driven cone wheel 42 are meshed together.

[0030] The end of the conveying pipe 2 away from the tee pipe 18 is provided with a connecting elbow 20, and the end of the suction pipe 3 is provided with a fixed elbow 21. The suction pipe 3 is located below the conveying pipe 2, and the axis of the suction pipe 3 is parallel to the axis of the conveying pipe 2. A connecting seat 22 is provided between the connecting elbow 20 and the fixed elbow 21. The connecting seat 22 is hollow. A connecting pipe 23 and a rotating pipe 24 are respectively provided on the connecting seat 22. One end of the connecting pipe 23 is connected to the fixed elbow 21, and the other end is connected to the rotating pipe 24 through a rotating interface 25. The end of the rotating pipe 24 away from the rotating interface 25 is connected to the fixed elbow 21. Both the connecting elbow 20 and the fixed elbow 21 are 90-degree elbows.

[0031] The connecting seat 22 is equipped with a conveying pipe 2 and a power assembly 5 for driving the sludge suction pipe 3 to rotate. The power assembly 5 includes a power motor 50 mounted on the connecting seat 22. The drive shaft of the power motor 50 is coaxially equipped with a driving bevel gear 51, and the rotating pipe 24 is coaxially equipped with a driven bevel gear 52. The driving bevel gear 51 and the driven bevel gear 52 are meshed together.

[0032] The end of the sludge suction pipe 3 away from the fixed elbow 21 is provided with a linkage elbow 30. In this embodiment, the linkage elbow 30 is a 90-degree elbow. The end of the linkage elbow 30 away from the sludge suction pipe 3 is provided with a sludge suction ring plate 31. The inner diameter of the sludge suction ring plate 31 increases from the side closer to the linkage elbow 30 to the side away from the linkage elbow 30. The sludge suction ring plate 31 faces the bottom wall of the sedimentation tank.

[0033] The invention also includes a controller for controlling the opening and closing of the power motor 50 and the drive motor 40 and their rotation angle. The controller is electrically connected to the power motor 50 and the drive motor 40. This allows the sludge removal time and the working path of the suction ring plate 31 to be set.

[0034] The implementation principle of Example 1 is as follows: First, the bottom plate 10 is fixed to the bottom wall of the sedimentation tank by welding or bolting, and then the equipment can be installed in the sedimentation tank.

[0035] During dredging, the pump is started to discharge the sludge along the suction ring plate 31, linkage elbow 30, suction pipe 3, fixed elbow 21, rotating pipe 24, rotating joint, connecting pipe 23, connecting elbow 20, conveying pipe 2, rotating pipe 15 and fixed pipe 14.

[0036] However, sedimentation tanks vary in size and shape. Therefore, the drive motor 40 can be started according to the size and shape of the sedimentation tank. The drive motor 40 drives the active cone wheel 41 and the driven cone wheel 42 to rotate, which in turn drives the rotating pipe 15 and the conveying pipe 2 to rotate. The conveying pipe 2 can then rotate around the central pipe 17, which in turn drives the sludge suction pipe 3 and the sludge suction ring plate 31 to rotate. However, the sludge suction ring plate 31 can only move in an arc around the central pipe 17, resulting in a small cleaning area. Moreover, the area behind the column 11 cannot be cleaned. Therefore, the drive motor 50 is used to drive the active bevel gear 51 and the driven bevel gear 52 to rotate, which in turn drives the rotating pipe 24, the fixed elbow 21, and the sludge suction pipe 3 to rotate around the connecting pipe 23. This can clean the sludge below the conveying pipe 2 and the area behind the column 11. Furthermore, the sludge suction pipe 3 can be extended, which extends the length of the conveying pipe 2 and expands the cleaning range.

[0037] Before cleaning, the path of the sludge suction pipe 3 is set according to the shape of the sedimentation tank and the obstacles in the sedimentation tank. When encountering obstacles, the sludge suction pipe 3 can be folded. When bypassing obstacles, the sludge suction pipe 3 can be unfolded for cleaning. This can help avoid obstacles and is conducive to adapting to sedimentation tanks with different complex conditions.

[0038] Example 2

[0039] Reference Figure 3-5The difference between this embodiment and embodiment 1 is that the linkage elbow 30 is provided with an installation groove 34 at one end near the suction ring plate 31, and a sealing rubber ring 32 is embedded in the installation groove 34. The sealing rubber ring 32 extends to the inside of the linkage elbow 30, and a mudguard 33 is provided on the suction ring plate 31 to insert into the linkage elbow 30. The mudguard 33 is set to abut against the sealing rubber ring 32.

[0040] The sealing effect between the mudguard 33 and the linkage elbow 30 is improved by the sealing rubber ring 32 abutting against the mudguard 33.

[0041] A connecting frame 6 is provided on the sludge suction pipe 3, and a fixed motor 60 is provided on the connecting frame 6. The fixed motor 60 is located below the sludge suction pipe 3. A rotating rod 61 is coaxially provided on the motor shaft of the fixed motor 60, and an incomplete gear 62 is coaxially provided on the rotating rod 61. The incomplete gear 62 is located below the fixed motor 60.

[0042] The connecting frame 6 is also provided with a positioning tube 63, which is located below the suction pipe 3. A lifting rod 64 is slidably provided inside the positioning tube 63. The lifting rod 64 extends into the positioning tube 63 and is fitted with a return spring 65. A power component 7 for driving the lifting rod 64 to move up and down is provided on the rotating rod 61.

[0043] The power component 7 includes a cam 70 mounted on a rotating rod 61. The cam 70 has a first arc surface 71 and a second arc surface 72. The second arc surface 72 corresponds to and is located below the incomplete gear set. The distance between the first arc surface 71 and the bottom wall of the sedimentation tank is greater than the distance between the second arc surface 72 and the bottom wall of the sedimentation tank. Two lifting arc surfaces 73 are provided between the first arc surface 71 and the second arc surface 72. The first arc surface 71, the second arc surface 72, and the two lifting arc surfaces 73 all face one side of the bottom wall of the sedimentation tank. The lifting rod 64 has an abutment rod 66 on one side extending out of the positioning tube 63. The end of the abutment rod 66 away from the lifting rod 64 has a rotating wheel 67 that abuts against the first arc surface 71, the second arc surface 72, and the two lifting arc surfaces 73. During normal sludge cleaning, the rotating wheel 67 is located at the first arc surface 71.

[0044] The lifting rod 64 has a drive gear 68 at the end away from the abutment rod 66. The drive gear 68 meshes with the incomplete gear 62. The mudguard 33 extends out of the suction pipe 3 and is mounted on the drive gear 68. The drive gear 68 has an installation ring 69. The mudguard 33 and the installation ring 69 are evenly distributed around the circumference of the lifting rod 64. The installation ring 69 is used to fit over the linkage elbow 30. A filter screen 600 is provided on the side of the installation ring 69 away from the suction pipe 3.

[0045] The arc length occupied by the second arc surface 72 is greater than the arc length occupied by the teeth of the incomplete gear 62, ensuring that when the drive gear 68 is rotated, the drive gear 68 is completely disengaged from the linkage bend 30, thus avoiding jamming.

[0046] The mounting ring 69 is provided with a guide arc surface 601 on the side near the suction pipe 3, and a magnet 602 that fits against the guide arc surface 601 is provided on the outer wall of the linkage elbow 30.

[0047] The implementation principle of Example 2 is as follows: Due to long-term sludge cleaning, all pipes are prone to residual sludge, which can easily clog the pipes over time. Therefore, the motor 60 is fixed to drive the rotating rod 61 to rotate, which in turn drives the cam 70 to rotate. The cam 70 squeezes the rotating wheel 67, and the rotating wheel 67 rolls along the first arc surface 71 and the lifting arc surface 73 to the second arc surface 72. The contact point gradually rotates from the highest point to the lowest point, forcing the lifting rod 64 to gradually move down. The reset spring 65 stretches and stores force, and the lifting rod 64 drives the drive gear 68 and the mudguard 33 to descend until the mudguard 33 and the linkage elbow 30 are separated and moved below the linkage elbow 30. During this process, the drive gear 68 slides along the incomplete gear 62.

[0048] As the cam 70 continues to rotate, the rotating wheel 67 rotates on the second arc surface 72. At this time, the contact point height of the rolling wheel remains unchanged. At this time, the incomplete gear 62 meshes with the drive gear 68 and drives the drive gear 68 to rotate, which can deflect the mudguard 33 away from the linkage bend 30. The drive gear 68 also drives the mounting ring 69 to rotate below the linkage bend 30, and the teeth of the incomplete gear 62 disengage from the drive gear 68.

[0049] As the cam 70 continues to rotate, the rotating wheel 67 rolls from the second arc surface 72 along the lifting arc surface 73 to the first arc surface 71. The contact point gradually rotates from the lowest point to the highest point. At this time, the return spring 65 resets, driving the lifting rod 64 to move upward, which in turn drives the mounting ring 69 to move upward. During this process, the drive gear 68 slides along the incomplete gear 62. At this time, the guide arc surface 601 is used to facilitate the mounting ring 69 to be fitted onto the outer wall of the linkage elbow 30. Moreover, the magnet 602 is used to improve the stability of the fixed mounting ring 69.

[0050] Then connect the fixed pipe 14 to the water pump and inject water into the fixed pipe 14, rotating pipe 15, conveying pipe 2, connecting pipe 23, rotating pipe 24 and sludge suction pipe 3. This can flush the inner wall of the above pipes, flush down the residual sludge, and filter the impurities with the filter screen 600. This can prevent the impurities from falling back into the sedimentation tank and prevent the pipes from getting blocked.

[0051] Furthermore, after the rubber sealing ring detaches from the mudguard 33, it extends out of the mounting groove 34. When the linkage elbow 30 is flushed with water, the rubber sealing ring can also be flushed, reducing the impact of residual sludge buildup at the rubber sealing ring on the sealing effect of the mudguard 33 when it is reinserted into the linkage elbow 30.

[0052] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
