Technical Field

[0001] The present invention belongs to the technical field of power insulator cleaning, and specifically relates to a robot for cleaning power insulators. Background Art

[0002] A power insulator is a device installed in a power system, mainly used to isolate the conductive part of an electrical equipment from the grounded part or other conductive parts to maintain electrical insulation. The insulator can withstand voltage and mechanical stress, ensuring the safe and stable operation of the power system.

[0003] In the prior art, at present, the cleaning of high-voltage support insulators mainly relies on manual wiping, high-pressure flushing and other methods. Manual operation has problems such as low efficiency and high danger; high-pressure flushing is prone to leaving grooves and causing secondary pollution; mechanical cleaning equipment is bulky and requires a complex loading device, and the operation is limited. For this reason, we propose a robot for cleaning power insulators. Summary of the Invention

[0004] The purpose of the present invention is to provide a robot for cleaning power insulators to solve the technical problems proposed in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A robot for cleaning power insulators includes a pillar, multiple groups of insulator bodies, and a fixed flange arranged between the multiple groups of insulator bodies. A cleaning mechanism is arranged outside the insulator body, and the cleaning mechanism includes: A cleaning component, including a control housing and two groups of connecting frames. Multiple groups of rolling brushes are rotatably connected inside the connecting frame through a first rotating shaft for cleaning the outer wall of the insulator body; Two groups of large gears are rotatably arranged inside the control housing through a second rotating shaft, and two groups of small gears are rotatably connected through a third rotating shaft. The connecting frame is fixed on the top of the large gear; Multiple groups of nozzles are fixedly arranged on the top of the connecting frame, a fixed pipeline is fixedly arranged on the top of the control housing, and two groups of installation hoses are fixedly arranged on the fixed pipeline.

[0006] Preferably, a first joint is fixedly arranged on the fixed pipeline, and a driving motor is fixedly arranged on the top of the control housing; Multiple groups of micro motors are fixedly arranged on the top of the connecting frame.

[0007] Preferably, two groups of protective plates are arranged outside the connecting frame.

[0008] Preferably, the cleaning component further includes a cleaning liquid tank. A connecting hose is arranged on the top of the cleaning liquid tank, and a plug is fixedly arranged at the end of the connecting hose.

[0009] Preferably, the cleaning mechanism further includes a lifting assembly. The lifting assembly includes a boom truck, an upper fixing fixture and a lower fixing fixture fixed outside the fixed flange. Four groups of flexible guide rails are fixedly arranged between the upper fixing fixture and the lower fixing fixture. Two electric hoists are arranged on the upper fixing fixture, and lifting steel wires are arranged on the electric hoists for lifting the connecting frame.

[0010] Preferably, a limiting plate is slidably arranged outside the flexible guide rail, and the limiting plate is fixedly connected with the connecting frame.

[0011] Preferably, an auxiliary flushing member is arranged above the limiting plate. The auxiliary flushing member includes an upper pipe fixed to the top of the limiting plate, and multiple groups of nozzles are arranged on the upper pipe for flushing foreign matters attached to the flexible guide rail; A connecting hose is fixedly arranged between the two upper pipes, and a second joint is fixedly arranged on the connecting hose.

[0012] Preferably, a protective member is arranged outside the nozzle. The protective member includes a rubber cover sleeved on the nozzle, and a connecting wire is fixedly arranged between the rubber cover and the nozzle.

[0013] Preferably, the lifting assembly includes a connecting frame and a wheeled cart arranged on one side of the control housing, and two telescopic rods are arranged on the wheeled cart.

[0014] Preferably, folding frames are arranged on both sides and the front and back of the telescopic rod, and stable support legs are arranged on the folding frames.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Through the designed cleaning mechanism of the present invention, the cleaning mechanism combines the rotation and cleaning of the rotary brush and the flushing of the nozzle to replace the traditional manual wiping and high-pressure flushing, realizing the automatic cleaning of the outer wall of the insulator, avoiding the danger of manual high-altitude operation, and greatly improving the cleaning efficiency at the same time. When multiple groups of rotary brushes rotate, the bristles contact each other alternately, which can synchronously remove the foreign matters attached to the surface of the bristles in the rotary brush, avoiding some foreign matters attached to the rotary brush from reattaching and polluting the insulator body. The up-and-down reciprocating movement of the cleaning assembly is realized through the electric hoist and the flexible guide rail, covering the full height range of the insulator, with flexible operation and adapting to insulator bodies of different sizes.

[0016] (2) Through the designed auxiliary flushing member of the present invention, water flow is sprayed onto the outer wall of the flexible guide rail through the nozzles at the top of the limiting plate, timely removing the foreign matters splashed and attached during the cleaning process, avoiding the wear between the guide rail and the limiting plate caused by the foreign matters, ensuring the smoothness and stability of the lifting process, and reducing the equipment maintenance frequency.

[0017] (3) The lifting assembly of the present invention is composed of a connecting frame, a wheeled trolley, a telescopic rod, a folding frame, and a stable support leg. The wheeled trolley enables the entire lifting assembly to have good mobility and can easily move between different sites, especially suitable for areas with complex terrain or limited space. Through the telescopic function of the telescopic rod, the cleaning assembly can be lifted to the top of the insulator body, simplifying the equipment deployment process and reducing the dependence on complex loading devices. This lifting assembly greatly simplifies the operation process, saves the preparation time before operation, and thus improves the overall operation efficiency, making the cleaning work of the power insulator body more efficient and convenient.

Detailed Embodiments

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0020] Embodiment 1 Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the present invention provides a technical solution: a robot for cleaning power insulators, including a pillar 100, multiple insulator bodies 101 installed on the top of the pillar 100, and a fixed flange arranged between the multiple insulator bodies 101. A cleaning mechanism is arranged outside the insulator body 101, and the cleaning mechanism includes: A cleaning component, including a control housing 211 arranged outside the insulator body 101 and two groups of connecting frames 216. A control box is arranged inside the control housing 211. The control box is the core control unit, which can receive instructions, deploy artificial intelligence algorithms, process data, coordinate the cooperation of various components, ensure the stable operation of the robot, and a camera is also arranged on the control housing 211. The camera scans the environment and locates to assist the robot in planning the cleaning path and positioning the clamping arm. Inside the connecting frame 216, multiple roller brushes 215 are rotatably connected through a first rotating shaft. The diameters of the multiple roller brushes 215 are different, which can facilitate contact with the insulator body 101. While the roller brushes 215 rotate simultaneously to clean the insulator body 101, self-cleaning of the roller brushes 215 can also be carried out. When the roller brushes 215 rotate, the outer sides of the multiple roller brushes 215 (the bristles on the outer sides of the roller brushes 215 are in staggered contact with each other) are in staggered contact with each other to clean the attached foreign objects on the outer sides of the roller brushes 215 from each other, for cleaning the outer wall of the insulator body 101; Two large gears 218 are rotatably arranged inside the control housing 211 through a second rotating shaft respectively, and two small gears 219 are rotatably connected through a third rotating shaft. The connecting frame 216 is fixed on the top of the large gear 218; Multiple spray nozzles 214 are fixedly arranged on the top of the connecting frame 216, a fixed pipeline 213 is fixedly arranged on the top of the control housing 211, and two installation hoses 217 are fixedly arranged on the fixed pipeline 213. The installation hoses 217 are communicated with the spray nozzles 214; A first joint 212 is fixedly arranged on the fixed pipeline 213, a driving motor 210 is fixedly arranged on the top of the control housing 211, and the working end of the driving motor 210 extends into the control housing 211 and is fixedly connected with the small gear 219; Multiple sets of micro motors 207 are fixedly arranged at the top of the connecting frame 216, and the working ends of the micro motors 207 are fixedly connected to the third rotating shaft; Two sets of protective plates 204 are arranged outside the connecting frame 216, and the protective plates 204 are fixedly connected to the connecting frame 216 by bolts, and the protective plates 204 can be disassembled and assembled as needed; The cleaning assembly further includes a cleaning liquid tank 201, which can supply cleaning liquid to the spray head 214. The cleaning water in the cleaning liquid tank 201 sequentially passes through the connecting hose, the fixed pipeline 213, and the installation hose 217 and enters the interior of the spray head 214. A connecting hose is arranged at the top of the cleaning liquid tank 201, and the end of the connecting hose passes through the interior of the control housing 211 and extends above the control housing 211. A plug is fixedly arranged at the end of the connecting hose, and the first connector 212 can penetrate into the interior of the plug.

[0021] Embodiment 2 On the basis of Embodiment 1, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 8 , the cleaning mechanism further includes a lifting assembly. The lifting assembly includes a boom truck 200, an upper fixing fixture 205 and a lower fixing fixture 202 fixed outside the fixed flange. Two sets of locking screws are connected to the inside of the right sides of the upper fixing fixture 205 and the lower fixing fixture 202 by threads, and the working ends of the locking screws are in contact with the fixed flange. The upper fixing fixture 205 and the lower fixing fixture 202 can be fixed respectively through the locking screws. A suspension frame is fixedly arranged between the top of the boom truck 200 and the upper fixing fixture 205. Four sets of flexible guide rails 203 are fixedly arranged between the upper fixing fixture 205 and the lower fixing fixture 202. Two electric hoists 206 are arranged on the upper fixing fixture 205. Lifting steel wires 209 are arranged on the electric hoists 206, and the bottom of the lifting steel wires 209 is fixedly connected to the top of the connecting frame 216 for lifting the connecting frame 216; A limiting plate 208 is slidably arranged outside the flexible guide rail 203. The limiting plate 208 can slide up and down on the flexible guide rail 203, and the limiting plate 208 is fixedly connected to the connecting frame 216.

[0022] In summary, when it is necessary to clean the insulator body 101, first use the boom truck 200 to hang structures such as the cleaning assembly, the upper fixing fixture 205, and the lower fixing fixture 202 above the insulator body 101. Then lower the structures such as the cleaning assembly, the upper fixing fixture 205, and the lower fixing fixture 202. At this time, both the upper fixing fixture 205 and the lower fixing fixture 202 on the cleaning mechanism are located outside the support ring at the top of the insulator body 101. Then first rotate the two sets of locking screws on the upper fixing fixture 205 in the direction close to the fixing flange. Then the working ends of the locking screws will contact and clamp the fixing flange, and the upper fixing fixture 205 can be fixed. Subsequently, move the lower fixing fixture 202 downward, driving the flexible guide rail 203 to descend accordingly. Then when it descends to a suitable position, rotate the two sets of locking screws on the lower fixing fixture 202 in the direction close to the insulator body 101 (when it descends to a suitable position, the lower fixing fixture 202 is located outside the fixing flange at the bottommost). Then the working ends of the locking screws will contact and clamp the bottommost fixing flange, and the lower fixing fixture 202 can be fixed. At this time, the four sets of flexible guide rails 203 between the upper fixing fixture 205 and the lower fixing fixture 202 will be straightened; Start multiple micro-motors 207 on the connecting frame 216 to drive the multiple sets of rotary brushes 215 below to rotate. The rotary brushes 215 rotate in opposite directions to each other. The rotary brushes 215 rotate to clean the outside of the insulator body 101. At the same time, multiple sets of nozzles 214 spray cleaning liquid to wash the outside of the insulator body 101. Cleaning and washing are carried out simultaneously. Then start the electric hoist 206. At this time, the winding rod on the electric hoist 206 rotates to unwind the wound lifting steel wire 209. Then the bottom of the lifting steel wire 209 descends to drive the connecting frame 216 to descend. Then the connecting frame 216 drives the corresponding control housing 211, the protective plate 204, multiple sets of rotary brushes 215 and other structures to descend accordingly. When it descends to a suitable position, the winding rod on the electric hoist 206 rotates in the reverse direction to wind up the lifting steel wire 209, driving the control housing 211, the protective plate 204, multiple sets of rotary brushes 215, multiple sets of nozzles 214 and other structures below to rise. Repeat this process multiple times. Clean the insulator body 101 by moving the rotating rotary brushes 215 up and down, and then wash the outside of the insulator body 101 by moving multiple sets of nozzles 214 up and down, so as to automatically clean the insulator body 101. After the cleaning is completed, operate in the reverse principle as described above to remove structures such as the upper fixing fixture 205 and the lower fixing fixture 202. Finally, use the boom truck 200 to remove structures such as the cleaning assembly, the upper fixing fixture 205, and the lower fixing fixture 202 for recycling and reuse, and they can be recycled; While the connecting rod 216 moves up and down, it will also drive the two sets of limiting plates 208 to move accordingly. At this time, the limiting plates 208 will slide up and down outside the flexible guide rail 203, which is used to limit the up and down movement of structures such as the connecting rod 216 and the control housing 211, thereby increasing stability.

[0023] Embodiment Three Based on Embodiment Two, please refer to Figure 1 , Figure 2 and 8 , an auxiliary flushing member is provided above the limiting plate 208. The auxiliary flushing member includes an upper pipe 301 fixed to the top of the limiting plate 208. A plurality of nozzles 300 are provided on the upper pipe 301, which are used to flush foreign matters attached to the flexible guide rail 203. A connecting hose 302 is fixedly provided between the two upper pipes 301. A second joint is fixedly provided on the connecting hose 302, and the second joint can be connected to an external water supply device.

[0024] In summary, during the up and down sliding of the limiting plate 208 on the flexible guide rail 203 during some cleaning processes, the foreign matters splashed onto the outer wall of the flexible guide rail 203 by being flushed by the spray head 214 and swept by the brush roller 215 are cleaned (to avoid abrasion of the outer wall of the flexible guide rail 203 and the inner wall of the limiting plate 208). During cleaning, the second joint on the fixed pipeline 213 is connected to an external water supply device, and then some water is transported to the nozzles 300, and the nozzles 300 flush the foreign matters attached to the outer wall of the flexible guide rail 203 to reduce abrasion.

[0025] Embodiment Four Based on Embodiment Three, please refer to Figure 3 , Figure 4 and Figure 5 , a protective member is provided outside the spray head 214. The protective member includes a rubber cover 401 sleeved on the spray head 214. The rubber cover 401 can cover and protect the spray orifice on the exposed spray head 214 when not in use, preventing some dust from entering the inside of the spray orifice and causing blockage, which affects the subsequent effect of the spray orifice spraying cleaning water outward. A connecting line 400 is fixedly provided between the rubber cover 401 and the spray head 214. Through the connecting line 400, when using the spray head 214, after opening the rubber cover 401, the rubber cover 401 can be connected to the spray head 214, which is convenient for covering the rubber cover 401 subsequently.

[0026] Through the protective member, the rubber cover 401 is fixed to the spray head 214 through the connecting line 400. When the device is idle, it covers the spray orifice of the spray head 214 to prevent dust and sundries from entering the inside and causing blockage, ensuring that the spray head 214 discharges water smoothly during subsequent cleaning and maintaining a stable flushing effect.

[0027] In summary, when multiple sets of rotary brushes 215 are rotating and the nozzle 214 is flushing, in order to reduce the outward splashing of some cleaning water and impurities, two sets of protective plates 204 provided externally are used for blocking and protection, reducing the probability of the cleaning water and impurities splashing outward. Moreover, the protective plate 204 can be disassembled by unscrewing the bolts, and the protective plate 204 can be disassembled and assembled as needed.

[0028] Embodiment 5 Based on Embodiment 4, please refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 9 The lifting assembly includes a connecting frame 500 and a wheeled cart 502 provided on one side of the control housing 211. The wheeled cart 502 can turn flexibly and can adapt to a variety of different road sections. Two sets of telescopic rods 501 are provided on the wheeled cart 502, and the telescopic rods 501 are fixedly connected to the connecting frame 500; Folding frames are provided on both sides and the front and back of the telescopic rod 501, and stable support legs 503 are provided on the folding frames. The stable support legs 503 can increase the stability of the wheeled cart 502, and the stable support legs 503 are hydraulic rods.

[0029] The lifting assembly designed by the present invention consists of a connecting frame 500, a wheeled cart 502, telescopic rods 501, folding frames and stable support legs 503. The setting of the wheeled cart 502 enables the entire lifting assembly to have good mobility and can be easily moved between different sites, especially suitable for areas with complex terrain or limited space. Through the telescopic function of the telescopic rods 501, the cleaning assembly can be lifted to the top of the insulator body 101, simplifying the equipment deployment process and reducing the dependence on complex loading devices. This lifting assembly greatly simplifies the operation process, saves the preparation time before operation, thereby improving the overall operation efficiency and making the cleaning work of the power insulator body 101 more efficient and convenient.

[0030] In summary, the wheeled cart 502 is moved to a suitable position on the ground outside the insulator body 101 (at this time, the two sets of connecting frames 216 in the open state enclose the support column 100), the folding frame is unfolded, and then the stable support legs 503 are opened to increase the stability of the wheeled cart 502 and prevent the wheeled cart 502 from tipping over. The driving motor 210 is started, and the working end of the driving motor 210 rotates to drive one set of small gears 219 fixedly connected thereto to rotate. Then, the small gears 219 drive the large gears 218 meshing therewith and another set of small gears 219 to rotate. The other set of small gears 219 drives another set of large gears 218 meshing therewith to rotate. At this time, the two sets of large gears 218 rotate in opposite directions, driving the two sets of connecting frames 216 to rotate in opposite directions (the two opened connecting frames 216 begin to close). At this time, the two closed connecting frames 216 drive the corresponding nozzles 214 and brush rollers 215 to move accordingly, and then the support column 100 can be wrapped. The multiple brush rollers 215 come into contact with and enclose the support column 100 (at this time, the outer sides of the brush rollers 215 contact the outer wall of the support column 100). Subsequently, the two telescopic rods 501 are started, and the top working ends of the telescopic rods 501 move upward and extend, driving the connecting frame 500 and the cleaning assembly to rise. Then, the brush rollers 215 come into contact with and move to the top position of the insulator body 101. Then, according to the above, the brush rollers 215 and the nozzles 214 in the cleaning assembly are opened, and then the cleaning assembly is reciprocated up and down to clean the outer wall of the insulator body 101 (the brush rollers 215 and the nozzles 214 will move up and down on multiple insulator bodies 101 and can pass through multiple fixed flanges without being blocked by the fixed flanges. Moreover, when passing through the fixed flanges, the dust and other foreign matters on the outer surfaces of the fixed flanges can also be cleaned). After the cleaning is completed, the wheeled cart 502 can be moved away according to the reverse principle described above, and the site returns to its original state.

[0031] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
