Description

Technical Field

[0001] This invention relates to the field of cable cleaning technology, and more particularly to a mobile robot for cleaning. Background Technology

[0002] A cable is a conductor made of one or more insulated conductors and an outer insulating protective layer, used to transmit electricity or information from one place to another. It plays a vital role in many fields of modern society, including power supply, communication transmission, and industrial control, and is an indispensable component of infrastructure construction and the operation of various equipment.

[0003] Because cables are exposed to the elements for extended periods, dust and bird droppings easily accumulate on their surfaces. During operation, cables generate heat, and dust buildup hinders heat dissipation, leading to increased cable temperature, accelerated insulation aging, and reduced cable lifespan. A search revealed CN112871939A, which discloses a high-altitude cable surface cleaning robot. This robot allows a sponge to adhere tightly to the cable during operation. The rotation of the cleaning device and the forward and backward movement of the clamping and walking device ensure effective cleaning of the cable. However, this cleaning device uses a sponge-wrapping and wiping method. After cleaning a certain length of cable, the sponge becomes clogged with dust and other impurities, reducing its cleaning effectiveness and requiring replacement. Furthermore, it is less effective at cleaning persistent impurities like bird droppings. Therefore, a mobile robot for cleaning is proposed. Summary of the Invention

The cleaning roller is provided with bristles. The second motor is mounted on the outer wall of the box cover. The output of the second motor... The shaft extends into the housing and is coaxially connected to a first gear. Half of the first gear ring is connected to the outer ring surface of each of the annular plates. The first gear meshes with the first gear ring. Half of the second gear ring is connected to the inner wall of the housing and the cover on the side away from the annular guide rail. The two second gear rings are coaxially arranged with the cable groove. A second gear is coaxially connected to the end of each shaft away from the annular plate. Both second gears mesh with the second gear rings. A deep cleaning unit is also provided inside the housing and the cover for deep cleaning of the cable surface and self-cleaning of the bristles.

[0008] Preferably, the deep cleaning unit includes four first electric telescopic rods and one second electric telescopic rod. A lifting plate is slidably connected to the bottom of the housing. The second electric telescopic rod is installed on the bottom outer wall of the housing. The movable end of the second electric telescopic rod extends into the housing and connects to the bottom of the lifting plate. A row of cleaning rods is provided on the lifting plate.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Reference Figure 1-7 As shown, a mobile robot for cleaning includes a housing 1, with a lid 11 rotatably connected to the top of the housing 1. The housing 1 and the lid 11 are provided with a connecting buckle 12. The housing 1 and the lid 11 are provided with circular and symmetrical cable grooves 14 on both sides. Each of the outer walls on both sides of the housing 1 is connected to a mounting bracket 13. Each mounting bracket 13 has a moving mechanism 2 at its other end for moving the housing 1 on the cable. A cleaning mechanism 3 is provided inside the housing 1 and the lid 11 to clean impurities attached to the surface of the cable.

[0025] In this embodiment, the moving mechanism 2 includes a housing 21, with openings at both ends and on the side walls. A fixed base 22 is installed on the bottom inner wall of the housing 21, and a traveling wheel 24 is rotatably connected to the fixed base 22. A movable base 23 is slidably connected to the top inner wall of the housing 21, and a traveling wheel 24 is rotatably connected to the movable base 23. A first motor 25 is installed on the outer wall of the housing 21, and the output shaft of the first motor 25 passes through the housing 21 and is coaxially connected to the traveling wheel 24 on the fixed base 22. A threaded rod 26 is threadedly connected to the top of the housing 21, and the lower end of the threaded rod 26 is rotatably connected to the movable base 23. A handwheel 27 is coaxially connected to the upper end of the threaded rod 26.

[0026] In this embodiment, the cleaning mechanism 3 includes a second motor 34. The inner walls of the box body 1 and the box cover 11 on the same side are each connected to a half-circular guide rail 31. Both circular guide rails 31 are coaxially arranged with the cable trough 14. A slider 311 is slidably connected to each circular guide rail 31, and a half-circular plate 32 is connected to each slider 311. Both annular plates 32 are coaxially arranged with the cable trough 14. A rotating shaft 33 is rotatably connected to each annular plate 32, and a cleaning roller 331 is coaxially connected to each rotating shaft 33. The cleaning roller 331 is provided with bristles 332. The second motor 34 is mounted on the outer wall of the box cover 11. The output shaft of the second motor 34 extends into the box body 1 and is coaxially connected to a first gear 341. A half-circular first gear ring 342 is connected to the outer ring surface of each annular plate 32. The first gear 341 and the first gear ring 342 are... The inner walls of the box body 1 and the cover 11 on the side away from the annular guide rail 31 are each connected to a half of a second gear ring 35. The two second gear rings 35 are coaxially arranged with the cable groove 14. The end of each rotating shaft 33 away from the annular plate 32 is coaxially connected to a second gear 351. Both second gears 351 mesh with the second gear rings 35. The box body 1 and the cover 11 are also provided with a deep cleaning unit for deep cleaning of the cable surface and self-cleaning of the bristles 332. When the box body 1 and the cover 11 are closed, the two half of the annular guide rail 31 will form a complete annular guide rail 31, so that the slider 311 can slide circumferentially on the two annular guide rails 31. At the same time, the two half of the first gear ring 342 will also form a complete first gear ring 342 and mesh with the first gear 341. The two half of the second gear ring 35 will also form a complete second gear ring 35 and mesh with the two second gears 351.

[0027] In this embodiment, the deep cleaning unit includes four first electric telescopic rods 362 and one second electric telescopic rod 38. A lifting plate 37 is slidably connected to the bottom of the box body 1. The second electric telescopic rod 38 is installed on the bottom outer wall of the box body 1. The movable end of the second electric telescopic rod 38 extends into the box body 1 and is connected to the bottom of the lifting plate 37. A row of cleaning rods 371 is provided on the lifting plate 37. Grooves 36 are provided on both sides of the box body 1 and the box cover 11 at the cable groove 14. The four first electric telescopic rods 362 are respectively installed in the four grooves 36. A baffle 361 is slidably connected in each groove 36. The movable end of the first electric telescopic rod 362 is connected to the baffle 361. A semi-circular notch with the same diameter as the cable diameter is provided on the baffle 361.

[0028] In this embodiment, half of the detection ring 15 is connected to the outer wall of the box body 1 and the box cover 11 on the side away from the second motor 34 to detect whether there are non-dust impurities attached to the cable surface. The two detection rings 15 are coaxially arranged with the cable groove 14. The two detection rings 15 are electrically connected to the control circuit of the four first electric telescopic rods 362, the second electric telescopic rods 38 and the first motor 25 through wires. When the visual camera of the detection ring 15 detects bird droppings or other non-dust impurities attached to the cable, it will control the first motor 25 to stop, so that the first electric telescopic rods 362 and the second electric telescopic rods 38 can start working.

[0029] In this embodiment, a first sealing strip 16 is provided on the contact surface between the box body 1 and the box cover 11, and a second sealing strip 363 is provided on each of the baffles 361. In order to ensure that the lifting plate 37 lifts the cleaning fluid without being affected when the box body 1 and the box cover 11 are sealed, small holes are provided at the bottom of the box body 1 and the top of the box cover 11 to maintain the pressure balance inside the box body 1 when the lifting plate 37 is raised and lowered. At the same time, the presence of the first sealing strip 16 and the second sealing strip 363 is to prevent the cleaning fluid from flowing out of the box body 1.

[0030] In this embodiment, the box 1, located above the lifting plate 37, contains cleaning fluid, which is mainly composed of water, alcohol and surfactant.

[0031] The working process and principle of this invention are as follows:

[0032] In use, first open the cover 11 and place the cable in the cable groove 14 of the box 1. Then close the cover 11 and place the cable in the moving mechanism 2 on both sides of the box 1, so that the cable is located on the walking wheel 24 of the fixed base 22 in the moving mechanism 2. Then turn the handwheel 27 to drive the threaded rod 26 to rotate. Under the action of the thread, the threaded rod 26 controls the moving base 23 to move closer to the fixed base 22, so that the walking wheel 24 on the fixed base 22 and the moving base 23 clamp the cable, thereby fixing the robot on the cable. By driving the walking wheel 24 to rotate through the first motor 25, the robot can move on the cable (the forward direction of the robot is the direction of the detection ring 15).

[0033] The second motor 34 is turned on, which drives the first gear 341 to rotate. The meshing of the first gear 341 with the first gear ring 342 drives the two half-ring plates 32 to rotate around the cable. The rotating shaft 33 on the ring plate 32 rotates with the ring plate 32. During the rotation, the second gear 351 meshes with the first gear ring 35. The rotating shaft 33 and the cleaning roller 331 revolve around the cable and rotate on their own axis, so that the bristles 332 continuously contact the cable surface. Driven by the first motor 25 and the second motor 34, the entire robot will move on the cable and clean the dust on the surface of the cable.

[0034] During the cleaning process, if the detection ring 15 detects bird droppings or other non-dust impurities attached to the cable, it will control the first motor 25 to stop. Since the first motor 25 requires a certain reaction time to stop, when the robot stops moving, the position of the bird droppings on the cable is exactly inside the box 1 and the box cover 11. Then, the first electric telescopic rod 362 is controlled to push the baffle 361 to move, clamping and wrapping the cable, filling the gaps between the box 1 and the cable. Afterwards, the second electric telescopic rod 38 pushes the lifting plate 37 to rise, causing the cleaning fluid level on the lifting plate 37 to rise continuously until it reaches a high level. At the height of the cable, the cable and the attached bird droppings are immersed in the cleaning solution. The cleaning solution softens the bird droppings, and the rotating cleaning roller 331 and brush 332 clean the bird droppings. This enables the robot to clean impurities such as bird droppings that have been stuck for a long time, improving the cleaning effect of the cleaning robot on the cable. During the cleaning process, the cleaning roller 331 rotates around the cable, while the brush 332 is agitated in the cleaning solution and comes into contact with the cleaning rod 371 on the lifting plate 37. This causes the dust and impurities carried during the previous cleaning to fall into the cleaning solution, achieving the self-cleaning effect of the brush and improving the cleaning ability of the subsequent brushes.

[0035] When the cleaning robot has cleaned a certain length of cable, and the cleaning ability of the bristles 332 carrying dirt decreases, the first motor 25 can be actively controlled to stop, and the above operation can be repeated to perform active self-cleaning of the bristles 332.

[0036] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
