Description

Technical Field

[0001] This invention relates to the field of radial flow secondary sedimentation tank cleaning machines, and more specifically to a radial flow secondary sedimentation tank cleaning robot. Background Technology

[0002] The secondary sedimentation tank is an important component of the activated sludge system in a wastewater treatment plant. Its main function is to clarify and concentrate the mixed liquor from the biological reaction tank, complete the sludge-water separation process, and return the activated sludge. Its operational performance directly affects the effluent quality and the concentration of returned sludge from the activated sludge system.

[0003] The growth of algae on the effluent weir of the secondary sedimentation tank directly affects the operation of the sewage treatment system. If it is not cleaned in time, it will block the effluent weir and affect the quality of the effluent.

[0004] Most existing secondary sedimentation tank cleaning devices are powered by batteries or solar panels, which provide the power for cleaning. However, batteries have limited energy storage, so the cleaning devices cannot work continuously. Solar panels have insufficient energy on cloudy days, resulting in poor overall cleaning effect on the secondary sedimentation tank. Summary of the Invention

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] Embodiments of the present invention:

[0039] See appendix Figure 1-5 A radial flow secondary sedimentation tank cleaning robot includes a mobile truss 1, a power mechanism, and a cleaning mechanism. The mobile truss 1 is located at the top of the sedimentation tank body 2, and one end of the mobile truss 1 is rotatably connected to the middle position of the sedimentation tank body 2. The power mechanism includes a connecting component 31, an adjusting component 33, and a driving component 32. The connecting component 31 is fixedly connected to one end of the mobile truss 1, and one end of the driving component 32 is hinged to the connecting component 31. The adjusting component 33 is used to adjust the angle between the connecting component 31 and the driving component 32. The cleaning mechanism is located above the effluent weir 21 of the secondary sedimentation tank and is used to clean the secondary sedimentation tank. The end of the driving component 32 away from the connecting component 31 contacts the cleaning mechanism and is electrically connected to the cleaning mechanism.

[0040] The movable truss 1 drives the connecting component 31 to rotate. The angle between the drive component 32 and the connecting component 31 can be adjusted by the adjusting component 33. When the cleaning mechanism needs to clean the secondary sedimentation tank, the connecting component 31 is brought into contact with the cleaning mechanism by the adjusting component 33. Under the action of the movable truss 1, the drive component 32 pushes the cleaning mechanism to move, and the end of the drive component 32 away from the connecting component 31 is in contact with the cleaning mechanism and electrically connected to the cleaning mechanism, so that the cleaning mechanism can clean the effluent weir 21. The overall cleaning is more convenient. The power supply is provided by electrical connection, avoiding the problems of using batteries or solar panels. At the same time, when the cleaning mechanism does not need to clean the effluent weir 21, the drive component 32 is moved away from the cleaning mechanism by the adjusting component 33, thereby realizing on-demand cleaning of the effluent weir 21.

[0041] The connecting assembly 31 includes a connecting frame 311, a first connecting plate 312, and a connecting block 314. One end of the connecting frame 311 is fixedly connected to the movable truss 1, and a second connecting plate 313 is fixedly connected to the other end of the connecting frame 311. The first connecting plate 312 is located on the upper side of the second connecting plate 313, and the connecting block 314 is located between the first connecting plate 312 and the second connecting plate 313. The connecting block 314 is used to fix the first connecting plate 312 and the second connecting plate 313.

[0042] The adjustment assembly 33 includes a telescopic rod 331 and a fixing block 332. One end of the telescopic rod 331 is hinged to one end of the second connecting plate 313, and the other end of the telescopic rod 331 is hinged to the fixing block 332.

[0043] The drive assembly 32 includes a drive rod 321 and a drive plate 322. One end of the drive rod 321 is hinged to the first connecting plate 312, and the other end of the drive rod 321 is fixedly connected to the drive plate 322. A fixing block 332 is fixedly connected to the drive rod 321. The drive plate 322 is used to contact the cleaning mechanism. An electrical connector is fixedly connected to the drive plate 322 and is fixedly connected to the cleaning mechanism. The angle between the drive rod 321 and the first connecting plate 312 is controlled by the extension and retraction of the telescopic rod 331, thereby adjusting the height of the drive plate 322. When the height of the drive plate 322 is low, it can contact the cleaning mechanism, thereby pushing the cleaning mechanism, and the electrical connector is fixedly connected to the cleaning mechanism. When the height of the drive plate 322 is high, the moving truss 1 drives the drive plate 322 to rotate and no longer contacts the cleaning mechanism.

[0044] The cleaning mechanism includes a housing 4, a first cleaning component 6, a second cleaning component 7, and a stabilizing component 5. Multiple movable holes 42 are provided on the lower side of the housing 4. The first cleaning component 6 is fixedly connected to the housing 4 and is used to clean the side walls of the water outlet weir 21. The second cleaning component 7 is fixedly connected to the housing 4 and is used to clean the tops of both sides of the water outlet weir 21. Multiple stabilizing components 5 are provided; one end of each stabilizing component 5 passes through the movable hole 42, one end of each stabilizing component 5 is hinged to the housing 4, and the other end of each stabilizing component 5 contacts the side walls of the water outlet weir 21.

[0045] The stabilizing component 5 includes a swing cylinder 51, a first rotating rod 57, a second rotating rod 83, a first spring 53, and a second spring 82. A hinge shaft 511 is fixedly connected to one end of the swing cylinder 51, and a hinge seat 43 is fixedly connected to the outer casing 4 near the movable hole 42. The hinge shaft 511 is hinged to the hinge seat 43. A connecting rod 59 is fixedly connected to one side of the swing cylinder 51. The first rotating rod 57 is located inside the swing cylinder 51, and one end of the first rotating rod 57 extends out of the swing cylinder 51 and is connected to a first roller 58. One end of the second rotating rod 83 is hinged to the connecting rod 59, and the other end of the second rotating rod 83 is connected to a second roller 84. One end of the first spring 53 is used to press against one side of the swing cylinder 51. One end of the second spring 82 is used to press against the second rotating rod 83.

[0046] Under the action of the first spring 53, the first roller 58 can always squeeze one side wall of the outlet weir 21. Under the action of the second spring 82, the second roller 84 can squeeze the top of the side wall of the outlet weir 21. Even if the secondary sedimentation tank cleaning robot walks on a plane that is not a regular circle, it can always be pressed between the two side walls of the outlet weir 21 under the action of the stabilizing component 5. This makes the secondary sedimentation tank cleaning robot more stable on the outlet weir 21 and prevents the secondary sedimentation tank cleaning robot from falling off the outlet weir 21 and being damaged. At the same time, the second roller 84 adopts a single-arm support, which allows the second roller 84 to be closer to the triangular weir, and it can also be used when the side walls on both sides of the outlet weir are thin.

[0047] The stabilizing component 5 also includes a first fixed rod 56, a first limiting cylinder 52, and a first limiting rod 55. The first fixed rod 56 is located on the lower side of the outer shell 4 and is fixedly connected to the outer shell 4. One end of the first limiting cylinder 52 is fixedly connected to one side of the swing cylinder 51. One end of the first limiting rod 55 is fixedly connected to the first fixed rod 56. A first spring 53 is sleeved on the first limiting rod 55, and one end of the first spring 53 presses against the swing cylinder 51. Through the hinge shaft 511 and the hinge seat 43 rotatably connected, and the first spring 53 sleeved on the first limiting rod 55, the swing cylinder 51 can swing to a certain extent, so that the first roller 584 can always press against the side wall of the outlet weir 21.

[0048] One end of the first limiting rod 55 is located inside the first limiting cylinder 52. The first limiting rod 55 is threaded and connected to an adjusting nut 54. One end of the first spring 53 is pressed against the adjusting nut 54, and the other end of the first spring 53 is pressed against the swing cylinder 51. When the swing amplitude of the swing cylinder 51 is too large, it can be limited by the first limiting rod 55 and the first limiting cylinder 52. The adjusting nut 54 can adjust the elastic force of the first spring 53.

[0049] The stabilizing component 5 also includes a second fixing rod 81 and a second limiting cylinder. The second fixing rod 81 is located on the lower side of the outer casing 4, with one end fixedly connected to the outer casing 4. One end of the second limiting cylinder is fixedly connected to one side of the second rotating rod 83, with one end of the second fixing rod 81 located inside the second limiting cylinder. A second spring 82 is sleeved on the second fixing rod 81, with one end of the second spring 82 pressing against the second rotating rod 83. By pressing the second rotating rod 83 against the second spring 82, the second roller 84 is always at the top of the side wall of the outlet weir 21. Even if there are irregular protrusions or depressions at the top of the side wall of the outlet weir 21, the stability of the support rod can be ensured under the action of the second spring 82.

[0050] The outer side of the outer casing 4 has a mounting hole, and a power supply connector 41 is fixedly connected in the mounting hole. The power supply connector 41 is electrically connected to the power mechanism.

[0051] The first cleaning assembly 6 includes a first motor 61 and a first brush head 62. The first motor 61 is located on the upper side of the housing 4 and is fixedly connected to the housing 4. The first brush head 62 is fixedly connected to the power output shaft of the first motor 61. The first brush head 62 is used to clean the sides of the water outlet weir 21. The second cleaning assembly 7 includes a second motor 71 and a second brush head 72. The second motor 71 is located on the upper side of the housing 4 and is fixedly connected to the housing 4. The second brush head 72 is fixedly connected to the power output shaft of the second motor 71. The second brush head 72 is used to clean the tops of both sides of the water outlet weir 21.

[0052] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
