Description

Technical Field

[0001] The invention belongs to the technical field of insulator cleaning, and in particular relates to an insulator cleaning device for live working. Background Art

[0002] Insulators are important electrical equipment in power systems, used to support and fix conductors and provide good insulation performance in high voltage environments. Due to long-term exposure to outdoor environments, dust, salt, bird droppings and other pollutants are easily accumulated on the surface of insulators, which can affect the operation of electrical equipment. Therefore, regular cleaning of insulators is a necessary measure to ensure the reliability of power systems.

[0003] For example, the patent with patent announcement number CN114669516A discloses a device for cleaning insulators during live working. The device for cleaning insulators during live working drives a cleaning brush head to move and clean the insulators by manually holding an insulating operating rod continuously. The axial directions of insulators at different positions are different, and the cleaning angle of the cleaning brush head also needs to be adaptively adjusted. However, due to the high working height, the device needs to be lowered to a lower height before the locking nut can be manually loosened to adjust the cleaning angle. The operation is cumbersome, and it is easy to cause hand fatigue after cleaning multiple insulators, affecting work efficiency and safety.

[0004] In view of the shortcomings of the above-mentioned prior art, an insulator cleaning device for live working with high automation is designed to overcome the shortcomings of the prior art and facilitate the cleaning of insulators at different positions and angles without the need for manual continuous holding of tools to avoid hand fatigue.

[0009] Preferably, there are three spray heads, three pump fluid cylinders and three piston rods, the three spray heads correspond to three cleaning brushes respectively, and the spraying direction of the spray heads is inclined toward the cleaning brushes.

[0010] Preferably, it also includes: a one-way output tube is connected between the first end of the pump fluid cylinder and the nozzle to output the cleaning agent in the pump fluid cylinder to the nozzle, and a one-way input tube is connected between the first end of the pump fluid cylinder and the liquid supply system to input the cleaning agent in the liquid supply system into the pump fluid cylinder.

Therefore, they cannot be understood as limitations on the present invention.

[0030] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] An insulator cleaning device for live working, such as Figure 1-Figure 4As shown, it includes a mobile base 1 with moving wheels at the bottom, an electric multi-section telescopic rod 2 arranged on the upper right side of the mobile base 1 and a support frame 42 located at the telescopic end of the electric multi-section telescopic rod 2, and a cleaning component 5 for cleaning insulators is arranged on the support frame 42. The position of the cleaning component 5 is transferred by using the mobile base 1, and the height of the cleaning component 5 is adjusted by controlling the telescopic movement of the electric multi-section telescopic rod 2, so as to facilitate the cleaning of insulators at different positions and heights; the telescopic end of the electric multi-section telescopic rod 2 is rotated through a rotating shaft 3 driven by a servo motor 31, and the servo motor 31 is installed at the telescopic end of the electric multi-section telescopic rod 2, and the output shaft of the servo motor 31 and the rear end of the rotating shaft 3 are both connected with a bevel gear 32, and the two bevel gears 3 2 are meshed, and the servo motor 31 is controlled to drive the two bevel gears 32 to rotate, thereby driving the rotating shaft 3 to rotate. The front end of the rotating shaft 3 is connected with an insulating support plate 4. The rotation of the rotating shaft 3 will drive the insulating support plate 4 to rotate. An electric guide rail 1 41 is installed on the insulating support plate 4. The rotation of the insulating support plate 4 will drive the electric guide rail 1 41 to rotate. The slider of the electric guide rail 1 41 is connected to the support frame 42. The rotation of the electric guide rail 1 41 will drive the cleaning component 5 to rotate through the support frame 42, and then the cleaning angle is adjusted according to the axial direction of different insulators. There is no need to cumbersomely control the electric multi-section telescopic rod 2 to lower the cleaning component 5 to manually adjust the cleaning angle. In addition, when the cleaning angle is adjusted, it is necessary to make the cleaning component 5 move along the axial direction of the insulator. When cleaning the insulator, the electric guide rail 41 is controlled to drive the support frame 42 to drive the cleaning component 5 to move back and forth. Since the servo motor 31 will also synchronously adjust the angle of the electric guide rail 41, the electric guide rail 41 is exactly parallel to the axial direction of the insulator, thereby ensuring the reciprocating cleaning of the insulators at different positions by the cleaning component 5. There is no need for manual continuous hand-held movement for cleaning, which greatly reduces the labor intensity of manual labor; a nozzle 61 for spraying cleaning agent on the insulator and a pump liquid cylinder 62 for conveying the cleaning agent to the nozzle 61 are provided on the support frame 42. A piston rod 65 that slides through the lower end of the pump liquid cylinder 62 is connected to one side of the insulating support plate 4 through a connecting plate 66. When the electric guide rail 41 drives the support frame 42 to drive When the cleaning component 5 moves back and forth to clean the insulator, the support frame 42 will drive the pump cylinder 62 to move, and the piston rod 65 will make a piston movement along the pump cylinder 62 on the basis of the insulating support plate 4 not moving. A liquid supply system 6 for providing cleaning agent to the pump cylinder 62 is provided on the movable base 1. As the piston rod 65 makes a piston movement in the pump cylinder 62, the pump cylinder 62 will transport the cleaning liquid provided by the liquid supply system 6 to the nozzle 61 for spraying. In this way, the nozzle 61 will automatically spray a certain amount of cleaning agent according to the distance the cleaning component 5 moves. When the electric guide rail 41 stops driving the cleaning component 5 to move, the nozzle 61 will also stop spraying the cleaning agent to prevent waste. The system has high automation and synchronization, thereby improving the cleaning efficiency and effect of the insulator.

[0032] like Figure 2 , Figure 5 and Figure 6 As shown, the cleaning assembly 5 includes a cleaning brush 50 rotatably arranged on a support frame 42, and the cleaning brush 50 is driven to rotate by a driving motor 51, and the driving motor 51 is installed on the support frame 42. Controlling the driving motor 51 can drive the cleaning brush 50 to rotate and clean the insulator; the support frame 42 has a U-shaped receiving opening, and the cleaning brush 50 has three, and the centers of the three cleaning brushes 50 respectively constitute the three corners of an equilateral triangle, and the three cleaning brushes 50 are respectively located at the two end points and a vertex of the receiving opening of the support frame 42, so that the insulator is located in the middle of the U-shaped receiving opening from the opening of the receiving opening of the support frame 42. At this time, the three cleaning brushes 50 surround the insulator, thereby cleaning the insulator in all directions.

[0033] like Figure 5 and Figure 6 As shown, the cleaning component 5 also includes a transmission component consisting of a synchronous pulley 52, a synchronous pulley 53 and a synchronous belt 54. The output shaft of the drive motor 51 and the three cleaning brushes 50 are connected with a synchronous pulley 52, and a synchronous belt 54 is jointly transmitted between the four synchronous pulleys 52, wherein the synchronous pulley 52 on the cleaning brush 50 at the two end points of the accommodating opening of the support frame 42 and the synchronous pulley 52 on the driving motor 51 are both located on the inner side of the synchronous belt 54, and the synchronous pulley 52 on the cleaning brush 50 at the vertex of the accommodating opening of the support frame 42 is located on the outer side of the synchronous belt 54, and two synchronous pulleys 53 are rotated on both sides of the support frame 42, which are respectively located on the inner and outer sides of the synchronous belt 54, and the synchronous belt 54 bypasses the synchronous pulley 53, and the transmission position of the synchronous belt 54 is limited by the synchronous pulley 53.

[0034] Preferably, the present embodiment has three nozzles 61, three pump cylinders 62 and three piston rods 65. The three nozzles 61 correspond to three cleaning brushes 50 respectively, and the spraying direction of the nozzle 61 is inclined toward the cleaning brush 50, so as to comprehensively spray the cleaning agent to the insulator and cooperate with the cleaning brush 50 for cleaning.

[0035] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, it also includes: a one-way output pipe 63 for outputting the cleaning agent in the pump liquid cylinder 62 to the nozzle 61 is connected between the first end (upper end) of the pump liquid cylinder 62 and the nozzle 61, a one-way input pipe 64 for inputting the cleaning agent in the liquid supply system 6 into the pump liquid cylinder 62 is connected between the first end of the pump liquid cylinder 62 and the liquid supply system 6, the one-way input pipe 64 is a flexible pipe, and the piston rod 65 slides through the second end (lower end) of the pump liquid cylinder 62. When the support frame 42 drives the cleaning component 5 and the pump liquid cylinder 62 to move upward, the cleaning component 5 first moves upward to clean the impurities on the surface of the insulator. Since the piston rod 65 does not move, the space in the pump liquid cylinder 62 will gradually increase at this time, and the cleaning agent in the liquid supply system 6 will be input from the one-way input pipe 64 into the pump liquid cylinder 62 , the one-way output pipe 63 temporarily stops outputting cleaning agent to the nozzle 61, thereby automatically completing the quantitative loading step of the cleaning agent according to the cleaning distance during the initial cleaning, thereby avoiding unnecessary waste of the cleaning agent; when the cleaning component 5 moves up and cleans once, the electric guide rail 41 is controlled to drive the support frame 42 to drive the cleaning component 5 and the pump fluid cylinder 62 to move down and reset. Since the piston rod 65 does not move, the space in the pump fluid cylinder 62 will gradually decrease, and the one-way input pipe 64 temporarily stops inputting cleaning agent to the pump fluid cylinder 62. The cleaning agent in the pump fluid cylinder 62 will be transported from the one-way output pipe 63 to be sprayed from the nozzle 61, so that when the cleaning component 5 cleans the surface of the insulator once and resets, the cleaning agent is sprayed synchronously for cleaning once, thereby automatically ensuring the reasonable application of the cleaning agent.

[0036] like Fig. 9 As shown, the liquid supply system 6 includes a liquid storage tank 601 connected to the upper side of the mobile base 1, and a suction pump 602 is installed on the upper side of the liquid storage tank 601. The water pumping end of the suction pump 602 extends to the inner bottom of the liquid storage tank 601, and the drainage end of the suction pump 602 is connected to the lower end of the one-way input pipe 64. The cleaning agent is injected into the liquid storage tank 601, and the suction pump 602 is controlled to suck the cleaning agent in the liquid storage tank 601 into the one-way input pipe 64 to achieve a continuous supply of the cleaning agent.

[0037] like Figure 2 , Figure 3 and Figure 8As shown, it also includes a connecting frame 7 connected to the upper side of the supporting frame 42, and three sliding rods 71 ​​are slidably arranged on the upper part of the connecting frame 7, and the three sliding rods 71 ​​correspond to the three cleaning brushes 50 respectively. The ends of the sliding rods 71 ​​are connected with cleaning cotton 72 located above the cleaning brush 50. When the cleaning brush 50 moves up to clean the insulator, the cleaning cotton 72 is in a retracted state. After the nozzle 61 sprays the cleaning agent and the cleaning brush 50 moves down to clean the insulator, the three cleaning cotton 72 are driven by the three sliding rods 71 ​​to approach each other to contact the insulator, so as to wipe the liquid remaining on the surface of the insulator after cleaning is completed; among the three sliding rods 71, the two sliding rods 71 ​​near the end points of the accommodating opening of the supporting frame 42 are connected with racks 1 74, and the left and right racks 1 74 are respectively parallel to the left and right sliding rods 71, and the other sliding rod 71 is parallelly connected with two left and right opposite racks 2 76, one of which is a rack 2 76. The two gears 75 are meshed with each other on the upper side of the connecting frame 7, and the rack 74 and the rack 76 are relatively meshed on both sides of the spur gear 75. Therefore, it is only necessary to drive the rear cleaning cotton 72 forward to the insulator through the rear slide bar 71. Under the action of the slide bar 71 driving the rack 2 76 to move and mesh with the spur gear 75, the spur gear 75 will drive the remaining slide bars 71 to drive the remaining cleaning cotton 72 to the insulator through the rack 1 74, so as to facilitate wiping. An electric guide rail 2 73 is installed on the upper side of the rear of the connecting frame 7. The slider of the electric guide rail 2 73 is connected to the slide bar 71 connected to the two racks 2 76, and the electric guide rail 2 73 is controlled to drive the rear slide bar 71 to drive the rear cleaning cotton 72 and the two racks 2 76 to move.

[0038] like Fig. 9 As shown, it also includes a hydraulic rod 11 rotatably arranged on the upper left side of the mobile base 1, and the electric multi-section telescopic rod 2 is rotatably arranged on the mobile base 1. The telescopic end of the hydraulic rod 11 is rotatably connected to one end of the electric multi-section telescopic rod rotatably arranged. Initially, the device is in an unfolded state. When the device needs to be transferred, the electric multi-section telescopic rod 2 is first controlled to retract, and then the hydraulic rod 11 is controlled to retract to drive the retracted electric multi-section telescopic rod 2 to swing to the left and retract, thereby reducing the accommodation height of the device and facilitating transfer to different places for cleaning insulators; in addition, the electric multi-section telescopic rod 2 is tilted by using the hydraulic rod 11, thereby driving the cleaning assembly 5 to tilt, and the adaptable working range can also be increased. When the lower position of the insulator to be cleaned is inconvenient to park, the insulator can be cleaned from the side position.

[0039] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. They only express the preferred implementation modes of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention.

[0040] It should be pointed out that, for ordinary technicians in this field, several modifications, increases and decreases in quantity, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
