Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology and relates to an insulator cleaning device. Background Technology

[0002] Insulators used in freight trains and electric locomotives are key components installed in the electrical systems of these vehicles to provide electrical insulation and mechanical support. Their core function is to isolate conductive components from the grounding structure during high-voltage electricity transmission, preventing current leakage, short circuits, and other faults. Simultaneously, they support electrical equipment and withstand mechanical stress, ensuring the safe and stable operation of the railway power system. Insulators are constantly exposed to the elements, and their surfaces easily accumulate dust, dirt, and other contaminants, leading to a decline in insulation performance. Therefore, regular cleaning of the insulator surface is necessary to prevent the formation of creepage paths.

[0003] Currently, the cleaning of insulator surfaces is often done manually, using cloths to wipe away dust, dirt, and other contaminants. However, manual cleaning is not only labor-intensive and time-consuming, but the cleaning quality cannot be guaranteed, reducing the efficiency of insulator cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide an insulator cleaning device that can avoid the time-consuming and labor-intensive problem of manual cleaning and improve the cleaning quality and efficiency of insulators.

[0008] At least three cleaning discs are set inside the arc-shaped guide rail and are evenly distributed along the length of the arc-shaped guide rail. The cleaning discs are connected to the arc-shaped guide rail by a swing arm, which is connected to an opening and closing mechanism.

[0012] The first gear is located inside the arc-shaped bracket and close to the first arc rack. The first gear is indirectly meshed with the first arc rack and is rotatably connected to the inner wall of the arc-shaped bracket.

[0013] The first motor is mounted on the arc-shaped bracket and positioned close to the first gear. The output end of the first motor passes through the arc-shaped bracket and connects to the first gear.

[0015] The opening and closing mechanism includes: The second arc rack has a hollow structure inside the arc-shaped guide rail. The second arc rack is set inside the arc-shaped guide rail and has an internal tooth arc. The outer side of the second arc rack is slidably connected to the inner wall of the arc-shaped guide rail.

[0016] The fifth gear is located inside the arc-shaped guide rail and is positioned close to the inner side of the second arc rack. The fifth gear meshes with the second arc rack.

[0017] The third motor is mounted on the arc-shaped guide rail and positioned close to the fifth gear. The output end of the third motor passes through the arc-shaped guide rail and connects to the fifth gear.

[0018] The three swing components correspond one-to-one with the positions of the three swing arms. Each swing component is connected to the corresponding swing arm and the second circular arc rack. Each swing component is used to drive the corresponding swing arm to swing through the second circular arc rack.

[0019] Each of the swing components includes: The sixth gear is located inside the arc-shaped guide rail and is positioned close to the corresponding rocker arm. The sixth gear meshes with the second arc rack.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] like Figure 1 , Figure 2As shown, this invention provides an insulator cleaning device, including an arc-shaped base 1, an arc-shaped bracket 2, a support member 3, an arc-shaped guide rail 8, at least three cleaning discs 4, a reciprocating rotation mechanism, and a lifting mechanism. The arc-shaped bracket 2 is coaxially arranged above the arc-shaped base 1, and the support member 3 is vertically arranged between the arc-shaped bracket 2 and the arc-shaped base 1. Through the cooperation of the arc-shaped base 1 and the arc-shaped bracket 2, the insulator can enter the arc-shaped base 1 and the arc-shaped bracket 2 from the opening position. The arc-shaped guide rail 8 is arranged on the inner side of the arc-shaped bracket 2 and is slidably connected to the inner side of the arc-shaped bracket 2, facilitating the sliding of the arc-shaped guide rail 8 along the inner side of the arc-shaped bracket 2. At least three cleaning discs 4 are arranged on the arc-shaped guide rail 8 and located inside the arc-shaped guide rail 8. The three cleaning discs 4 are evenly arranged along the length direction of the arc-shaped guide rail 8. Each cleaning disc 4 is connected to the arc-shaped guide rail 8 through a swing arm 5. The three swing arms 5 are connected to an opening and closing mechanism, which is used to drive the three cleaning discs 4 to release or clamp the insulator. The invention comprises an arc-shaped base 1, an arc-shaped support 2, an arc-shaped guide rail 8, at least three cleaning discs 4, a lifting mechanism, and a lifting mechanism. The former is connected to the arc-shaped support 2 and the latter to the support 3 and the arc-shaped support 2, respectively. The latter is used to adjust the height of the arc-shaped support 2 so that the three cleaning discs 4 can clean different positions of the insulator. Through the cooperation of the arc-shaped base 1, the arc-shaped support 2, the support 3, the arc-shaped guide rail 8, at least three cleaning discs 4, the reciprocating mechanism, and the lifting mechanism, the invention achieves this by using the reciprocating mechanism to drive the arc-shaped guide rail 8 to reciprocate along the arc-shaped support 2, thereby driving the three cleaning discs 4 to reciprocate and clean the insulator. The latter, using the lifting mechanism to adjust the height of the arc-shaped support 2, allows the three cleaning discs 4 to clean different positions of the insulator, thus avoiding the time-consuming and labor-intensive problem of manual cleaning and improving the cleaning quality and efficiency of the insulator.

[0037] like Figure 2 , Figure 3As shown, the reciprocating rotation mechanism includes a first arc rack 6, a first gear 12, and a first motor 9. The first arc rack 6 is disposed inside the arc-shaped bracket 2, and its position is close to the arc-shaped guide rail 8. The first arc rack 6 has an external tooth arc, and its inner surface is connected to the outer surface of the arc-shaped guide rail 8. The first gear 12 is disposed inside the arc-shaped bracket 2, and its position is close to the first arc rack 6. The first gear 12 and the first arc rack 6 are indirectly meshed and connected. The first gear 12 and the arc-shaped bracket 2 are also connected. The inner wall is rotatably connected, and multiple transmission gears are provided between the first gear 12 and the first arc rack 6. Each transmission gear is rotatably connected to the inner wall of the arc bracket 2. Adjacent transmission gears are meshed.

The first motor 9 is mounted on the arc bracket 2. The position of the first motor 9 is close to the first gear 12. The output end of the first motor 9 passes through the arc bracket 2 and is connected to the first gear 12.

[0038] like Figure 4 , Figure 5 As shown, the inner wall of each swing arm 5 is hollow. A second gear 13 is provided near the corresponding cleaning plate 4 in each swing arm 5. The second gear 13 is rotatably connected to the inner wall of the swing arm 5 through a vertically arranged rotating shaft. The lower end of the rotating shaft passes through the swing arm 5 and connects to the corresponding cleaning plate 4. A third gear 14 is provided on the inner wall of each swing arm 5 away from the second gear 13. A second motor 10 is provided on each swing arm 5 near the third gear 14. The output end of the second motor 10 passes through the swing arm 5 and connects to the third gear 14. At least one fourth gear 15 is provided between the third gear 14 and the second gear 13. The fourth gear 15 is rotatably connected to the inner wall of the swing arm 5. The fourth gear 15 meshes with the third gear 14 and the second gear 13 respectively. There are multiple fourth gears 15. Two adjacent fourth gears 15 mesh with each other. The fourth gear 15 near the third gear 14 meshes with the third gear 14. The fourth gear 15 near the second gear 13 meshes with the second gear 13.

[0039] like Figure 6 , Figure 7As shown, the opening and closing mechanism includes a second arc rack 7, a fifth gear 18, a third motor 11, and three swing components. The arc-shaped guide rail 8 has a hollow internal structure. The second arc rack 7 is set inside the arc-shaped guide rail 8 and has an internal tooth arc. The outer side of the second arc rack 7 is slidably connected to the inner wall of the arc-shaped guide rail 8. The fifth gear 18 is set inside the arc-shaped guide rail 8 and is located close to the inner side of the second arc rack 7. The fifth gear 18 is meshed with the second arc rack 7. The third motor 11 is set in the arc-shaped guide rail 8 and is located close to the fifth gear 18. The output end of the third motor 11 passes through the arc-shaped guide rail 8 and is connected to the fifth gear 18. The three swing components correspond one-to-one with the positions of the three swing arms 5. Each swing component is connected to the corresponding swing arm 5 and the second arc rack 7. Each swing component is used to drive the corresponding swing arm 5 to swing through the second arc rack 7, thereby driving the corresponding cleaning disc 4 away from or towards the insulator.

[0040] like Figure 7 As shown, each swing assembly includes a sixth gear 19 and a drive shaft. The sixth gear 19 is set inside the arc-shaped guide rail 8 and is positioned close to the corresponding swing arm 5. The sixth gear 19 meshes with the second arc rack 7. The drive shaft is vertically set inside the arc-shaped guide rail 8, and the sixth gear 19 is sleeved on the drive shaft. Both ends of the drive shaft are rotatably connected to the inner wall of the arc-shaped guide rail 8. One end of the drive shaft passes through the arc-shaped guide rail 8 and is connected to the corresponding swing arm 5.

[0041] like Figure 4 , Figure 5 As shown, each cleaning disc 4 is equipped with two cleaning brushes. Each cleaning brush has a ring structure, which makes it easy for each layer of the insulator to be inserted between the two cleaning brushes, so as to facilitate thorough cleaning of the insulator and further improve the cleaning quality of the insulator.

[0042] like Figure 1 , Figure 2 As shown, the lifting mechanism includes a first up-and-down moving component and a second up-and-down moving component. The first up-and-down moving component has a moving end, which is connected to the arc-shaped bracket 2 and is used to drive the arc-shaped bracket 2 to move up and down. The second up-and-down moving component has a moving end and a fixed end. The moving end is connected to the first up-and-down moving component, and the fixed end is connected to the support member 3. The second up-and-down moving component is used to drive the first up-and-down moving component to move up and down. Through the cooperation of the first up-and-down moving component and the second up-and-down moving component, it can adapt to insulators of different heights.

[0043] like Figure 1 , Figure 2As shown, the first vertical moving assembly includes a U-shaped mounting plate, a first lead screw, a guide rod, a first slider, and a fourth motor. The U-shaped mounting plate is vertically disposed between the arc-shaped bracket 2 and the support member 3. The side of the U-shaped mounting plate is slidably connected to the side of the support member 3. The first slider is disposed inside the U-shaped mounting plate. The arc-shaped bracket 2 is connected to the side of the first slider away from the U-shaped mounting plate. The first lead screw is vertically disposed between the U-shaped mounting plates. The first lead screw passes through the first slider and is threadedly connected to the first slider. Both ends of the first lead screw are rotatably connected to the inner walls of both ends of the U-shaped mounting plate. The fourth motor is disposed on the U-shaped mounting plate near one end of the first lead screw. The output end of the fourth motor passes through the U-shaped mounting plate and is connected to the end of the first lead screw. The guide rod is vertically disposed inside the U-shaped mounting plate. The guide rod is parallel to the first lead screw. Both ends of the guide rod are fixedly connected to the inner walls of both ends of the U-shaped mounting plate. The guide rod passes through the first slider and is slidably connected to the first slider.

[0044] like Figure 1 , Figure 2 As shown, the second vertical moving component includes a hollow motor, a nut, a second lead screw, and a second slider. The support member 3 has a portal-shaped structure. The second lead screw is vertically installed inside the support member 3, and its two ends are fixedly connected to the inner wall of the support member 3. The nut is installed inside the hollow motor, and the second lead screw passes through the nut and is threadedly connected to it. The second slider is installed between the hollow motor and the U-shaped mounting plate, and is connected to both the hollow motor and the U-shaped mounting plate. When the hollow motor is started, it drives the nut to rotate, and the nut moves up and down along the second lead screw, thereby driving the U-shaped mounting plate to move up and down.

[0045] like Figure 1 , Figure 2 As shown, the lower part of the arc-shaped base 1 is provided with multiple adsorption components 16, which are used to adsorb the arc-shaped base 1 onto the roof of the vehicle. Each adsorption component 16 is a vacuum suction cup or an electromagnet.

[0046] like Figure 1 , Figure 2 As shown, an optical fiber through-beam sensor 17 is installed on the upper part of the arc-shaped bracket 2. The optical fiber through-beam sensor 17 is electrically connected to a controller. The controller is electrically connected to the first motor 9, each of the second motors 10, the third motor 11, the fourth motor, and the electric push rod. Through the setting of the controller and the optical fiber through-beam sensor 17, the cleaning of the insulator can be carried out automatically, which further improves the cleaning efficiency of the insulator.

[0047] Each cleaning pan 4 has a hollow interior and is used to store cleaning fluid. Each cleaning pan 4 has a water pipe interface on its upper part and multiple water outlets evenly distributed near the two cleaning brushes. The water pipe interface is connected to the outlet of the water pump through a water supply pipe, and the inlet of the water pump is connected to water containing cleaning agent. The water pump is electrically connected to the controller, and the controller is electrically connected to the electrical control cabinet through a cable. When the water pump is started, the water containing cleaning agent is delivered into each cleaning pan 4 and then sent to the two cleaning brushes through the multiple water outlets to clean the insulators.

[0048] Working principle: When in use, place this device near the insulator that needs to be cleaned, so that the insulator enters the arc-shaped base 1 and arc-shaped bracket 2 through the opening position, and the insulator is positioned in the center of the three cleaning discs 4, and the three cleaning discs 4 clamp the insulator to complete the positioning of the insulator in the plane direction. Then, the multiple adsorption parts 16 at the bottom of the arc-shaped base 1 are adsorbed onto the roof of the vehicle, and the three cleaning discs 4 release the insulator to complete the fixation of the tool.

[0049] The controller then controls the hollow motor to move the arc-shaped bracket 2 and the fiber optic photoelectric sensor 17 on it upward to the top layer of the insulator. Then, the fiber optic photoelectric sensor 17 moves downward from the top layer of the insulator. The controller records the current height position of the fiber optic photoelectric sensor 17 when it passes through each layer of the insulator, thereby obtaining the specific position of each layer in the height direction of the insulator.

[0050] Next, the three cleaning discs 4 are moved upwards to the top layer of the insulator. The controller starts the third motor 11, which drives the fifth gear 18 to rotate. The fifth gear 18 drives the second arc rack 7 to rotate within the arc-shaped guide rail 8. The arc-shaped guide rail 8 drives the three sixth gears 19 to rotate. Each sixth gear 19 drives the corresponding swing arm 5 to swing through the corresponding transmission shaft, so that the three swing arms 5 drive the three cleaning discs 4 to move towards the insulator. Each cleaning disc 4 contacts the top layer of the insulator, causing the top layer of the insulator to engage two cleaning brushes. In between, the third motor 11 stops, and the controller then controls the three second motors 10 and the first motor 9 to start. Each second motor 10 drives the rotating shaft to rotate through the third gear 14, the fourth gear 15, and the second gear 13. The rotating shaft drives the cleaning disc 4 to rotate. At the same time, the first motor 9 drives the first gear 12 to rotate back and forth. The first gear 12 drives the first arc rack 6 to rotate forward and then reverse (the rotation angle is 120 degrees to 180 degrees), and so on. Through the rotation of the three cleaning discs 4 and their reciprocating rotation around the insulator, the top layer of the insulator is cleaned.

[0051] After the top layer of the insulator is cleaned, the three cleaning discs 4 are opened by controlling the fourth motor to drive the first lead screw to rotate. The first lead screw drives the arc bracket 2 and the three cleaning discs 4 to move downward through the first slider. Under the action of the fiber optic photoelectric sensor 17, it stops at the next layer of the insulator. The above steps are repeated until each layer of the insulator is cleaned.
