Description

Technical Field

[0001] The invention relates to the technical field of electric power engineering, and in particular to an insulator anti-fouling structure. Background Art

[0002] In the power transmission and distribution system, insulators are key electrical equipment components. Their role is to ensure that the current is effectively isolated between the conductor and the ground, thereby maintaining the safe and stable operation of the power system. However, in the complex and changing natural environment, various dirt easily accumulates on the outside of the insulator, such as industrial dust, smoke particles, bird droppings, and residues after melting snow. These dirt not only affect the appearance of the insulator, but more importantly, they will significantly reduce the insulation performance of the insulator and increase the risk of flashover accidents.

[0003] Chinese patent publication number CN116759170A is a flashover protection structure for cable insulators in power projects. The structure covers the insulators with two sets of cleaning brushes designed with an enclosing structure through the coordinated use of a driving mechanism and a cleaning mechanism, ensuring that the cleaning brushes can fully contact the outer wall of the insulator, thereby improving and ensuring the cleaning effect and efficiency, reducing the risk of flashover of insulators, and providing protection for the safety of power projects. The movable ring plate and cleaning brush enable the structure to clean and protect insulators of different specifications, broadening the scope and scenarios of application.

DETAILED DESCRIPTION

[0041] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] See also Figure 1-Figure 8As shown, an insulator anti-fouling structure comprises a mounting plate 1 for mounting the insulator, a threaded block 2 slidingly arranged on the mounting plate 1 in a horizontal straight direction, a rotary driver 3 mounted on the mounting plate 1 for driving the threaded block 2 to rotate, a pair of brush blocks 31 arranged on the threaded block 2 in a horizontal straight direction and used for cleaning the outside of the insulator, a collecting box 4 for collecting rainwater, a cover plate 41 arranged on the collecting box, and a linkage flushing moving mechanism 5 arranged on the mounting plate 1 for flushing dirt on the outside of the insulator and timely wiping the insulator after flushing, the linkage flushing moving mechanism 5 comprises a shielding piece 51 for controlling the opening and closing of rainwater and a sponge block 52 for wiping the insulator after flushing, and a limiting mechanism 6 for driving the sponge block 52 to adjust the position according to the external shape of the insulator, a displacement groove 21 for the brush block 31 to move relatively close to and away from, and a means for driving the brush block 31 to always be in contact with the insulator is provided in the displacement groove 21. The lifting spring in external contact can drive the brush block 31 to contact and clean the insulator along the displacement groove 21 when the threaded block 2 slides in the horizontal straight direction, so that the brush block 31 can always contact and clean the outside of the insulator. The rotary driver 3 is preferably a servo motor. The mounting plate 1 is provided with a controller for controlling the start and shutdown of the servo motor. The output end of the rotary driver 3 is connected to a threaded rod 211 through a coupling. The threaded rod 211 is threadedly connected to the threaded block 2. The mounting plate 1 is provided with a plurality of avoidance grooves for rainwater discharge, which can prevent rainwater from accumulating on the mounting plate 1 after flushing the outside of the insulator. The collection box 4 is provided with a drainage port 511 for rainwater to pass through. The drainage port 511 matches the size of the shielding plate 51. A plurality of drainage ports 511 are regularly arranged along the intervals between the insulators. Each drainage port 511 is located at the interval position between each insulator. The cover plate 41 is provided with an entry groove for rainwater to pass through. The entry groove can also reduce the entry of impurities or dust.

[0043] When it is necessary to clean the impurities or dirt attached to the outside of the insulator, first start the rotary driver 3 through the controller. When the rotary driver 3 is started, the connected threaded rod 211 can be rotated. When the threaded rod 211 is rotated, the threaded block 2 connected by the thread can be driven to slide in the horizontal straight line direction. In this process, the brush block 31 can be driven to contact and clean the insulator, and then the threaded block 2 continues to slide in the horizontal straight line direction. In this process, the linkage flushing moving mechanism 5 can contact the shielding piece 51 and cause the shielding port to lose its shielding of the drain port 511, and then the rainwater collected in the collection box 4 can flow out through the drain port 511. After flowing out, the outside of the insulator below can be flushed. Since the drain port 511 is located between the spacing between each insulator, the rainwater can contact the insulator in advance, thereby improving the cleaning effect of the brush block 31 on the outside of the insulator, and the sponge block 52 can be used to perform secondary cleaning on the insulator during the cleaning process, thereby avoiding dirt on the outside of the insulator that has not been removed.

[0044] See also Figure 5-Figure 7 As shown, the linked flushing movement mechanism 5 also includes a first contact block 53, a second contact block 54, a positioning rod 55 and an elastic pull rope 56; the first contact block 53 is arranged on the threaded block 2; the second contact block 54 is arranged on the shielding piece 51 and is used to contact the first contact block 53; the positioning rod 55 is arranged on the collecting box 4 and has a plurality of positioning rods 55, and the positioning rods 55 are used to limit the tilting swing of the shielding piece 51; the elastic pull rope 56 is respectively arranged on the collecting box 4 and the shielding piece 51, and the elastic pull rope 56 is used to pull the shielding piece 51 to perform a tilting swinging motion.

[0045] When the threaded block 2 slides in a horizontal straight line direction, the first contact block 53 fixed thereto can be driven to contact the second contact block 54 provided on the shielding piece 51 during the process. When in contact, the shielding piece 51 can be driven to open at an inclined angle along the positioning rod 55, and the elastic pull rope 56 is in a taut state during the process. At this time, the discharge outlet that is no longer blocked by the shielding piece 51 can discharge the rainwater in the collection box. When the first contact block 53 is not in contact with the second contact block 54, the elastic pull rope 56 can pull the shielding piece 51 to the initial position again, and the discharge outlet can be blocked. When the brush block 31 is moved for cleaning, the outside of the insulator can be flushed by rainwater first. When used in conjunction with the brush block 31, the cleaning effect of dirt attached to the outside of the insulator is improved.

[0046] See also Figure 8-Figure 10As shown, the limiting mechanism 6 includes a connecting guide plate 61, a placement box 62, a sliding plate 63 and a limiting groove 64; the connecting guide plate 61 is arranged on the mounting plate 1 and has a pair; the placement box 62 is slidably arranged on the connecting guide plate 61 in a horizontal straight line direction and has a pair, the placement box 62 is used to place the sponge block 52 and is close to the outside of the insulator; the sliding plate 63 is arranged on the placement box 62; the limiting groove 64 is opened on the connecting guide plate 61 and slidably cooperates with the sliding plate 63, the sponge block 52 is a concave shape that better fits the shape of the insulator, and the placement box 62 is provided with a plurality of through grooves for the sponge block 52 to be squeezed and then drained.

[0047] When the brush block 31 moves, the sponge block 52 arranged in the placement box 62 can be driven to move synchronously. When the placement box 62 moves, the sliding plate 63 can be driven to slide intermittently close to and away from the outside of the insulator along the limiting groove 64 provided on the connecting guide plate 61, so that when the brush block 31 slides in a horizontal straight direction, the limiting groove 64 can drive the sliding plate 63 and the placement box 62 to always fit the outside of the insulator, thereby avoiding the problem of dirt adhering to the outside of the insulator.

[0048] See also Figure 8-Figure 10 As shown, the limiting mechanism 6 also includes a connecting plate 65 and a matching block 66; the connecting plate 65 is arranged on the placement box 62 and is located below the threaded block 2; the matching block 66 is arranged on the threaded block 2 and is loosely matched with the connecting plate 65, and the matching block 66 is used to limit the sliding of the connecting plate 65 in the horizontal straight direction.

[0049] In the process of the placement box 62 and the sliding plate 63 moving along the limiting groove 64, in order to prevent the placement box 62 and the sliding plate 63 from rotating along the limiting groove 64, the placement box 62 can slide stably in the horizontal straight line direction under the restriction of the matching block 66 set on the connecting plate 65 and the threaded block 2 during the process of relatively approaching and moving away from the outside of the insulator, so that the placement box 62 and the sponge block 52 can slide stably in the relative approach and relative distance, and can always be in contact with the outside of the insulator.

[0050] See also Figure 8 and Fig. 9 As shown, the limiting mechanism 6 also includes a linear groove 67, a guide block 68, a travel groove 69 and a limiting rod 691; the linear groove 67 is provided on the connecting guide plate 61; the guide block 68 is provided on the placement box 62 and is located in the linear groove 67 for sliding in a horizontal linear direction; the travel groove 69 is provided on the guide block 68; the limiting rod 691 is provided in the linear groove 67 and slidingly cooperates with the travel groove 69.

[0051] When the placement box 62 moves toward and away from the outside of the insulator, during this process, a straight groove 67 can be opened on the connecting guide plate 61 through the guide block 68 fixedly connected thereto for stable sliding in the horizontal straight direction, and during this process, a limiting rod 691 is arranged in the straight groove 67 to slide the travel groove 69 opened on the guide block 68, which makes the placement box 62 and the sponge block 52 more stable when sliding in the horizontal straight direction.

[0052] See also Fig.10 and Fig.11 As shown, the insulator anti-fouling structure also includes a linkage scraping mechanism 7 arranged on the mounting plate 1 for cleaning impurities or dust accumulated on the cover plate 41; the linkage scraping mechanism 7 includes a first rotating rod 71, a transmission belt 72, a rotating contact rod 73 and a cleaning block 74; the first rotating rod 71 is rotatably arranged on the collection box 4 and is located above the threaded rod 211; the transmission belt 72 is respectively arranged on the first rotating rod 71 and the threaded rod 211, and the transmission belt 72 is used to transmit the rotational force of the threaded rod 211 to the first rotating rod 71; the rotating contact rod 73 is arranged on the first rotating rod 71 and is coaxially fixed with the first rotating rod 71; the cleaning block 74 is horizontally and linearly slidably arranged on the cover plate 41 and has a plurality of cleaning blocks, and the cleaning blocks 74 are used to scrape and clean impurities or dust on the cover plate 41.

[0053] When the threaded rod 211 rotates, the transmission belt 72 can drive the first rotating rod 71 connected thereto to rotate synchronously. When the first rotating rod 71 rotates, the rotating contact rod 73 coaxially fixed thereto can be driven to move the cleaning block 74. Since the cleaning block 74 fits the surface of the cover plate 41, the cleaning block 74 can slide in a horizontal straight line direction when the rotating contact rod 73 rotates. During the sliding, the impurities or dust accumulated and attached to the surface of the cover plate 41 can be effectively cleaned.

[0054] The linkage scraping mechanism 7 also includes a contact sliding block 75, a circular rod 76, a limiting plate 77 and a first return spring 78; the contact sliding block 75 is arranged on the cover plate 41 in a horizontal straight line direction and has a pair; the circular rod 76 is arranged on the cover plate 41 and has a clearance fit with the contact sliding block 75; the limiting plate 77 is arranged on the cleaning block 74 and has a plurality of them; the first return spring 78 is arranged on the circular rod 76 and is fixed to the end of the contact sliding block 75.

[0055] When the rotating contact rod 73 is rotated, the rotating contact rod 73 can be driven to contact the contact sliding block 75. During this process, the first return spring 78 is in a compressed state, causing the contact sliding block 75 to slide in a horizontal straight line direction along the circular rod 76 with a clearance fit set on the cover plate 41. Since there are several contact sliding blocks 75 and cleaning blocks 74, and each cleaning block 74 is connected by a limiting plate 77, when one contact sliding block 75 moves, it can drive multiple contact sliding blocks 75 to move synchronously, thereby effectively cleaning impurities or dust on the cover plate 41. When the rotating contact rod 73 is not in contact with the contact sliding block 75, the compressed first return spring 78 is released and pushes the contact sliding block 75 to move and reset in a horizontal straight line direction along the circular rod 76, so that when the rotating contact rod 73 rotates, the cleaning block 74 can be driven to clean impurities or dust on the cover plate 41 with clearance.

[0056] See also Figure 8-Figure 12 As shown, the insulator anti-fouling structure also includes a contact drying mechanism 8 arranged on the mounting plate 1 and used to squeeze out water from the sponge block 52 after wiping; the contact drying mechanism 8 includes a fixed plate 81, an extrusion block 82, a movable groove 83 and a displacement block 84; the fixed plate 81 is arranged on the mounting plate 1; the extrusion block 82 is slidably arranged on the fixed plate 81 in a horizontal straight direction and has a pair; the movable groove 83 is opened on the fixed plate 81 and has a pair; the displacement block 84 is slidably arranged on the movable groove 83 in a horizontal straight direction and is fixedly connected to the fixed plate 81.

[0057] When the threaded block 2 drives the placement box 62 and the sponge block 52 to move, until the placement box 62 and the sponge block 52 move to the side close to the fixed plate 81, in this process, the placement box 62 can first contact with the fixed plate 81, and when in contact, the extrusion block 82 and the displacement block 84 can move relatively away in the horizontal straight line direction along the moving groove 83 opened on the fixed plate 81. In this process, the extrusion block 82 can squeeze out water from the sponge block 52 after wiping. When the rotary driver 3 drives the threaded rod 211 to rotate in the opposite direction, the sponge block 52 and the placement box 62 can be driven back to their initial positions. During the resetting process, since the sponge block 52 is in a dry state after being squeezed by the extrusion block 82, the sponge block 52 can wipe and dry the residual moisture on the outside of the insulator in time during the resetting process, so that the insulator can remain dry after being cleaned, preventing the insulator from getting wet, thereby restoring or maintaining its original insulation strength and improving the service life of the insulator.

[0058] See also Fig.12 and Fig.13As shown, the contact drying mechanism 8 also includes a sliding stroke plate 85 and an oblique groove 86; the sliding stroke plate 85 is arranged in a horizontal straight line direction on the fixed plate 81 and is located below the extrusion block 82; the oblique groove 86 is opened on the sliding stroke plate 85 and has a pair, the oblique groove 86 is located below the movable groove 83, and the oblique groove 86 is slidably matched with the displacement block 84.

[0059] When the placement box 62 contacts the fixed plate 81, the sliding stroke plate 85 can first contact the placement box 62, and during the contact process, the sliding stroke plate 85 can slide in the horizontal straight direction. During the sliding process, the displacement block 84 can slide in the horizontal straight direction relatively away from each other along the oblique groove 86 on the sliding stroke plate 85 and the movable groove 83 on the fixed plate 81, so that when the placement box 62 and the sponge block 52 are cleaned, the sponge block 52 that is saturated with adsorption can be automatically squeezed out of water through the squeezing block 82, so that the sponge block 52 remains dry.

[0060] See also Fig.13 As shown, the contact drying mechanism 8 also includes a travel rod 87 and a first telescopic spring 88; the travel rod 87 is arranged on the fixed plate 81 and is used to limit the sliding travel plate 85 from sliding in a horizontal straight direction away from and close to the fixed plate 81, and the travel rod 87 and the sliding travel plate 85 are clearance-matched; the first telescopic spring 88 is arranged on the travel rod 87, and the two ends of the first telescopic spring 88 are respectively fixed to the travel rod 87 and the end of the sliding travel plate 85.

[0061] When the sliding stroke plate 85 contacts the placement box 62 and slides in the horizontal straight direction, the sliding stroke plate 85 can slide stably along the stroke rod 87 with clearance fit, and in this process the first telescopic spring 88 is compressed. When the placement box 62 and the sponge block 52 are not in contact with the sliding stroke plate 85, the compressed first telescopic spring 88 can slide the moving sliding stroke plate 85 along the stroke rod 87 in the horizontal straight direction and reset it, and in the process of resetting the sliding stroke plate 85, drive the displacement block 84 and the extrusion block 82 to move relatively away, thereby achieving the resetting effect of the extrusion block 82 and the displacement block 84.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
