Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a cleaning and coating robot. Background Technology

[0002] Outdoor power transmission lines generally use bare conductors, but bare conductors are often affected by the environment and are prone to power failures. Therefore, it is currently necessary to spray an insulating layer on the surface of the bare conductors to prevent power failures in the power transmission lines.

[0003] Current coating methods typically employ manual or machine spraying. Manual spraying suffers from low efficiency, high operational risks, and inconsistent coating results. While machine spraying improves efficiency, existing coating robots lack the ability to clean the surface of bare wires. Dust, bird droppings, and other impurities accumulated on the surface of bare wires degrade the coating effect, resulting in an uneven and easily peeling insulation layer. Therefore, existing technologies require further improvement. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 The present invention provides a technical solution: a cleaning and coating robot, including a material storage device 1, a material extrusion device 2, a wiring device 3, and a spraying device 4. The material extrusion device 2 is located on one side of the material storage device 1 and can slide back and forth inside the material storage device 1. The wiring device 3 is located on the top of the material storage device 1. The spraying device 4 is connected to the material storage device 1 and is located on one side of the wiring device 3. A cleaning device 5 is located on the other side of the wiring device 3, and a dust collection device 6 is located below the cleaning device 5.

[0033] Please see Figure 7To reduce the size of the robot and allow the cleaning device 5 to open and avoid obstacles during mounting, in this embodiment, preferably, two cleaning devices 5 are symmetrically arranged. Each cleaning device 5 includes a first telescopic rod 51, a base 52, a second telescopic rod 53, a flip plate 54, a third telescopic rod 55, and a top frame 56. The output end of the first telescopic rod 51 is connected to the base 52, the bottom of the flip plate 54 is hinged to the base 52, the output end of the second telescopic rod 53 is hinged to the flip plate 54, and its other end is hinged to the base 52. One side of the top of the flip plate 54 is connected to the third telescopic rod 55, the output end of the third telescopic rod 55 is connected to the top frame 56, and a brush 57 is connected to the side of the top frame 56 away from the third telescopic rod 55.

[0034] The purpose is to drive the brush 57 away from the surface of the power transmission line by the third telescopic rod 55, drive the flip plate 54 to flip at a certain angle along the hinge point to form an open state by the second telescopic rod 53, and further drive the flip plate 54 and brush 57 to move away from the power transmission line by the first telescopic rod 51, increasing the relative distance between the two top frames 56 to achieve a position avoidance effect, making it convenient to hang the cable routing device 3 on the power transmission line, and making it convenient to remove or install the dust bag 63. The two-stage translation composed of the first telescopic rod 51 and the third telescopic rod 55 increases the travel distance and can effectively reduce the lateral width and volume of the robot, making it easy to carry. After the hanging is completed, the flip plate 54 and brush 57 are driven to move closer to the power transmission line by the first telescopic rod 51, and then the flip plate 54 is driven to flip at the hinge point to a vertical state by the second telescopic rod 53. Finally, the brush 57 is driven to move and stick to the surface of the power transmission line by the third telescopic rod 55, and the surface of the power transmission line is cleaned by driving the brush 57 to rotate.

[0035] Please see Figure 8To improve cleaning efficiency, in this embodiment, preferably, several brushes 57 are evenly arranged along the horizontal plane and rotatably connected to the top frame 56. A first motor 58 is mounted on the top frame 56. The brushes 57 are cylindrical and include a cylinder 571 and several bristles 572 connected to the surface of the cylinder 571. A transmission assembly 59 is connected to the bottom of the brushes 57. The transmission assembly 59 includes a first gear 591 and a second gear 592. The first gear 591 is fixed to the bottom of the brushes 57, and the second gear 592 meshes with the first gear 591. Two adjacent first gears 591 are connected to the first gear 592. Two gears 592 are meshed together, with one of the second gears 592 connected to the output shaft of the first motor 58. The purpose is to drive the second gear 592 to rotate through the first motor 58, which in turn drives the first gear 591 to rotate. Simultaneously, the second gear 592 drives the adjacent second gear 592 to rotate, which in turn drives the corresponding first gear 591 to rotate. In turn, each first gear 591 drives the corresponding brush 57 to rotate, and adjacent brushes 57 rotate in opposite directions. By using multiple brushes 57 with different directions of rotation, the cleaning effect is greatly improved.

[0036] Please see Figure 9 To facilitate the suction of raised dust, in this embodiment, preferably, the dust collection device 6 includes a suction pipe 61, a second motor 62, and a dust filter bag 63. The dust filter bag 63 is disposed inside the suction pipe 61, the second motor 62 is disposed below the dust filter bag 63, and its top output shaft is connected to an impeller 64. The top of the suction pipe 61 is provided with a suction port 65, and one side of its bottom is connected to an exhaust pipe 66. The suction port 65 is disposed on the lower inner side of the cleaning device 5. The purpose is to drive the impeller 64 to rotate through the second motor 62, so that the raised dust is sucked into the dust filter bag 63 by negative pressure through the suction port 65, and the dust is collected and temporarily stored through the dust filter bag 63.

[0037] Please see Figure 6 In order to facilitate the structure of upward air intake and downward air exhaust to effectively reduce the load pressure, in this embodiment, preferably, the exhaust pipe 66 includes a horizontal pipe 661 and a vertical pipe 662. One end of the horizontal pipe 661 is connected to the dust suction pipe 61, and the other end is vertically connected to the vertical pipe 662. The opening of the vertical pipe 662 is set downward, so that the exhaust is discharged downward through the vertical pipe 662 and the air is sucked upward through the dust suction port 65, thereby effectively reducing the load pressure while suctioning dust.

[0038] Please see Figure 4To facilitate the loading and unloading efficiency of the dust bag 63, in this embodiment, preferably, the bottom of the dust bag 63 is evenly distributed with several ventilation holes 67 to facilitate negative pressure suction, and the top of the dust bag 63 is provided with a support ring 68, the bottom of which abuts against the top of the suction pipe 61. The purpose is to allow the dust bag 63 to be directly inserted into the suction pipe 61 from the suction port 65. The bottom of the support ring 68 abuts against the top of the suction pipe 61 to form a limit, eliminating the need for locking and fixing, making installation more convenient. When the dust bag 63 needs to be cleaned or replaced, it can be directly removed, thereby achieving the effect of convenient installation or disassembly of the dust bag 63.

[0039] In order to make reasonable use of space, reduce volume and improve structural stability, in this embodiment, preferably, the storage device 1 includes a paint fixing frame 11, with a storage tank 12 on both sides of the paint fixing frame 11, and a battery 13 fixedly installed in the middle, so as to make reasonable use of space, reduce volume and improve structural stability.

Two driven gears 25 are symmetrically arranged and are respectively meshed with the two sides of the driving gear 24. The third motor 23 is located inside the paint fixing frame 11, and its output end is connected to the driving gear 24. The third motor 23 drives the driving gear 24 to rotate, and then drives the driven gear 25 to rotate through the driving gear 24.

[0041] The feeding assembly 21 is symmetrically arranged with two sets, each including a slide rail 211 and a screw 212. One end of the screw 212 is connected to a feeding plate 213, and the other end is connected to a slider 214. The feeding plate 213 is slidably connected to the storage tank 12. The driven gear 25 is provided with a nut 215 that is connected to the screw 212. The slider 214 is slidably connected to the top of the slide rail 211. The driven gear 25 drives the screw 212 to move linearly through the rotation of the nut 215, thereby causing the screw 212 to push the paint through the feeding plate 213, pushing the paint to one end. When the screw 212 drives the feeding plate 213 to push the paint, it moves along the slide rail 211 through the slider 214, improving the stroke accuracy.

[0042] The bottom of each of the two slide rails 211 is connected to a mounting bracket 216, and an electrical control box 7 is connected between the two mounting brackets 216. This makes reasonable use of space, reduces volume and improves structural stability. The battery 13 is electrically connected to the electrical control box 7, the extrusion device 2, the wiring device 3 and the spraying device 4 respectively. The mounting bracket 216 is fixedly connected to the transmission frame 22.

[0043] To facilitate observation of the insulation layer coating status, in this embodiment, preferably, the coating device 4 is equipped with a camera.

[0044] To facilitate transportation and improve safety, in this embodiment, preferably, the cable routing device 3 includes a front cable routing mechanism 31 and a rear cable routing mechanism 32. The front cable routing mechanism 31 and the rear cable routing mechanism 32 are connected by a transmission mechanism, and a handle 8 is connected between the front cable routing mechanism 31 and the rear cable routing mechanism 32. The purpose is that maintenance personnel can transport and carry the invention through the handle 8, and when the maintenance personnel load it by a crane, they can load the invention onto the power transmission line through the handle 8. The handle 8 is not made of insulating material, and the handle 8 can keep the maintenance personnel away from the power transmission line, improving the safety during loading.

[0045] In order to facilitate maintaining the robot at the same potential as the power transmission line and to record the spraying distance, in this embodiment, preferably, the inner side of the front wiring mechanism 31 is provided with a length measuring device that can swing up and down, and the inner side of the rear wiring mechanism 32 is provided with an equipotential device that can swing up and down.

[0046] To facilitate maintaining the robot at the same electrical potential as the power transmission line and recording the spraying distance, in this embodiment, preferably, the length measuring device includes a measuring wheel 9, which is hinged to the front wiring mechanism 31 via a first torsion spring. The equipotential device includes a pressure tongue 10, which is hinged to the rear wiring mechanism 32 via a second torsion spring. The purpose is that during use, the first torsion spring provides torque to the measuring wheel 9, ensuring that the measuring wheel 9 is always in contact with the power transmission line. When the front wiring mechanism 31 moves along the power transmission line, the measuring wheel 9 follows the front wiring mechanism 31 in real time and records the moving distance. In addition, the second torsion spring provides torque to the pressure tongue 10, ensuring that the pressure tongue 10 is always in contact with the power transmission line, so that the present invention maintains an equipotential state with the power transmission line during the mounting process.

[0047] Please see Figure 6 In order to improve structural stability and reduce load pressure, in this embodiment, preferably, the first telescopic rod 51 is fixed to one side of the mounting frame 216 to improve structural stability. The suction pipe 61 and the horizontal pipe 661 are both fixed to the top of the electrical control box 7, and the vertical pipe 662 is set on the side of the electrical control box 7 near the transmission frame 22. The purpose is to effectively reduce load pressure by the upward suction and downward exhaust structure.

[0048] Please see Figure 6 In order to make reasonable use of space and reduce the size of the cleaning and coating robot, in this embodiment, preferably, a clearance cavity 219 is provided between the electrical control box 7 and the transmission frame 22, and the vertical pipe 662 is set in the clearance cavity 219.

[0049] Please see Figure 5To facilitate improved material feeding smoothness and reliability, in this embodiment, preferably, bearings 217 are connected to both sides of the bottom of the slider 214. The lower side of the bearing 217 abuts against the slide rail 211. The slide rail 211 is arranged in an upward-opening "U" shape, and a limiting strip 218 is connected to its top. The limiting strip 218 is located above the bearing 217. Its purpose is to improve stroke accuracy by moving the slider 214 along the slide rail 211 when the screw 212 drives the pusher plate 213 to push the material, and to make the bearing 217 roll when the slider 214 moves by abutting against the slide rail 211 through the lower side of the bearing 217, thereby reducing friction and improving material feeding smoothness. The limiting strip 218 prevents the bearing 217 from deviating from the slide rail 211, thereby improving structural reliability.

[0050] The working principle and usage process of this invention are as follows: In actual use, a crane lifts the maintenance personnel to one side of the power transmission line for mounting. The maintenance personnel use the handle 8 to mount the cleaning and coating robot's wiring device 3 onto the power transmission line. By keeping the pressure tongue 10 in contact with the power transmission line, the cleaning and coating robot maintains an equipotential state with the power transmission line during mounting. Then, the wiring device 3 drives the cleaning and coating robot to move along the power transmission line. The meter wheel 9 follows the front wiring mechanism 31 in real time and records the moving distance. While the cleaning and coating robot is moving, the cleaning device 5 cleans the surface of the power transmission line in front of the cleaning and coating robot to ensure that the surface of the power transmission line is clean. The dust raised by the cleaning is sucked in by the dust suction device 6 to prevent contamination of the subsequent insulation layer sprayed. The spraying device 4 sprays the insulation layer onto the surface of the power transmission line from behind the cleaning and coating robot, so that the insulating coating is evenly adhered to the clean surface of the power transmission line.
