[0002] High-voltage porcelain insulators refer to insulators used in high-voltage and ultra-high-voltage overhead transmission lines and substations. In order to meet the needs of different voltage levels, different numbers of single insulators of the same type are usually used to form insulator strings or multi-section insulating pillars.

[0003] The surface of high-voltage porcelain insulators is easily affected by dust and other dirt, which reduces its insulation and increases the conductive path on the surface of the insulator, thereby causing flashover breakdown and easily causing insulator cracking.

[0019] Technical effects and advantages of the present invention:

[0020] 1. In the present invention, a protruding end is fixed on the outer side of the first shed and the second shed. When it rains, rain drops on the surface of the first shed and the second shed and gathers on the surface of the first shed and the second shed due to the obstruction of the protruding end. A plurality of notches are provided on the protruding end, and the corresponding notches on the two protruding ends are arranged alternately. In this way, rainwater gathered on the upper surface of the first shed and the second shed adjacent to each other can flow out through the notches arranged alternately, thereby reducing the phenomenon of forming a continuous water column and thus not damaging the insulation of the insulator itself.

[0021] 2. In the present invention, multiple rotating rings and cleaning mechanisms are independently arranged, so that a conductive structure continuously arranged along the height direction of the insulator is not formed, so that even if there is current or static electricity on the surface of the insulator, it cannot be directly transmitted to the lower end of the insulator through the rotating ring and the cleaning mechanism, thereby achieving the purpose of cleaning without damaging the insulation performance of the insulator itself;

[0022] 3. The present invention can utilize wind power to smoothly drive the cleaning plate to rotate without the need for electrical connection;

[0023] 4. When the rotating piece is in contact with the first intercepting column or the second intercepting column, it is in an inclined state, and the wind entering the ventilation slot can be smoothly guided to the bottom of the extended plate to push the extended plate to slide upward; and when the wind force drives the rotating piece to rotate, the wind force passes through the small ventilation gap, causing the rotating piece to vibrate, thereby generating sound, playing the role of a wind whistle, having the function of driving away birds, preventing birds from resting or nesting on the insulator, and making it difficult for bird droppings and other stains to form on the surface of the insulator, and having strong practicality;

[0024] 5. In the present invention, when the cleaning plate rotates, it also accelerates the rainwater on the surface of the corresponding first umbrella skirt or second umbrella skirt to flow out from the notch, so as to prevent the rainwater on the surface of the first umbrella skirt or second umbrella skirt from gathering too much and flowing out directly from the outer edge of the protruding end;

[0025] 6. The wind plate in the present invention is also driven by wind, so that the cleaning plate rotates, and the surface of the wind plate is a reflective surface. When the wind plate rotates, the principle of reflecting light is used to make birds think that the area has been occupied or poses a risk, thereby preventing birds from staying near the insulator, effectively protecting the insulator from bird intrusion;

[0026] 7. Due to the repulsion between the two magnetic blocks, the upper and lower adjacent wind plates can always be staggered, avoiding collision between the upper and lower wind plates when the wind plates rotate; and also avoiding the formation of continuous rain columns by rainwater flowing along the wind plates;

[0027] 8. When the rotating ring rotates, the collision ball will intermittently hit the fixed ball. Due to the hitting effect, the cleaning plate, the first umbrella skirt or the second umbrella skirt will vibrate to a certain extent, which is conducive to cleaning the dust; and when there is rainwater on the surface of the first umbrella skirt or the second umbrella skirt, it can promote the rainwater to flow along the upper surface of the first umbrella skirt or the second umbrella skirt to its outer edge;

[0028] 9. The detachable connection of the protruding end is convenient for direct application on the existing insulator, without the need to replace the insulator as a whole. It has a broad application prospect and is easy to disassemble and replace. The protruding end also serves as a guide rail when the cleaning plate rotates, avoiding the phenomenon of the cleaning plate end tilting upward and causing poor cleaning effect, thereby increasing the service life.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention provides Figure 1-Figure 7 A high-voltage porcelain insulator with improved insulation capacity is shown, comprising a core rod 1, a first shed 2 and a second shed 3 are fixed to the outer side of the core rod 1, a plurality of first shed 2 and second shed 3 are provided, and the first shed 2 and second shed 3 adjacent to each other are equidistantly distributed, which is a common insulator structure currently available and will not be described in detail herein.

[0039] In the present invention, the outer sides of the first umbrella skirt 2 and the second umbrella skirt 3 are coated with potassium silicate coating to form a hard, transparent, glass-like coating with good insulation properties, and are suitable for high-temperature insulation of quartz, ceramics, metals, etc., to improve insulation performance.

[0040] In the prior art, when it rains, rainwater falls on the surfaces of the first shed 2 and the second shed 3 and then directly drips downward through the outer edges of the first shed 2 and the second shed 3. Sometimes, when the rainwater is too heavy, a continuous water column is formed, which causes the phenomenon of damaging the insulation of the insulator itself. Therefore, in the present invention, a protruding end 4 is fixed on the outer side of the first shed 2 and the second shed 3. When it rains, rainwater falls on the surfaces of the first shed 2 and the second shed 3 and then gathers on the surfaces of the first shed 2 and the second shed 3 due to the obstruction of the protruding end 4. A plurality of notches 5 are provided on the protruding end 4, and the corresponding notches 5 on the two protruding ends 4 are staggered. In this way, the rainwater gathered on the upper surfaces of the first shed 2 and the second shed 3 adjacent to each other can flow out through the staggered notches 5, thereby reducing the phenomenon of forming a continuous water column and thus not damaging the insulation of the insulator itself.

[0041] In order to solve the problem that the self-cleaning device of the insulator in the prior art easily increases the conductive path on the surface of the insulator and destroys its insulation, in the present invention, a rotating ring 6 is rotatably arranged on the outer ring of the core rod 1, and a plurality of rotating rings 6 are arranged. Each corresponding upper surface of the first umbrella skirt 2 and the second umbrella skirt 3 is provided with a rotating ring 6, and a cleaning mechanism 7 is fixed to the outer side of the rotating ring 6, and the bottom end of the cleaning mechanism 7 is in contact with the corresponding upper surface of the first umbrella skirt 2 and the second umbrella skirt 3; when the rotating ring 6 rotates, the cleaning mechanism 7 moves along the upper surface of the first umbrella skirt 2 or the second umbrella skirt 3, so as to achieve the purpose of cleaning the first umbrella skirt 2 and the second umbrella skirt 3. Based on the independent arrangement of the plurality of rotating rings 6 and the cleaning mechanism 7, a conductive structure continuously arranged along the height direction of the insulator will not be formed, so that even if there is current or static electricity on the surface of the insulator, it cannot be directly transmitted to the lower end of the insulator through the rotating ring 6 and the cleaning mechanism 7, so that the cleaning purpose is achieved without destroying the insulation performance of the insulator itself.

[0042] The cleaning mechanism 7 in the present invention includes a cleaning plate 31, and a wiping block 20 is installed at the bottom end of the cleaning plate 31. The bottom end of the wiping block 20 is attached to the upper surface of the corresponding first umbrella skirt 2 or the second umbrella skirt 3. When the cleaning mechanism 7 rotates, the wiping block 20 cleans the upper surface of the first umbrella skirt 2 or the second umbrella skirt 3.

[0043] Considering that the insulator itself is usually installed at a high position and is not easy to electrically connect to the cleaning mechanism or clean manually, an extension groove 14 is provided at the top of the cleaning plate 31, and an extension plate 15 is slidably fitted in the extension groove 14. Ventilation grooves 13 are provided on both sides of the long side of the cleaning plate 31, and the extension grooves 14 are connected to the ventilation grooves 13. When natural wind enters the ventilation grooves 13, the extension plate 15 is pushed to extend from the extension grooves 14, so that the force surface formed by the extension plate 15 and the cleaning plate 31 is increased, so that the wind force can be used to smoothly drive the cleaning plate 31 to rotate; no electrical connection is required.

[0044] It should be noted that the extension plate 15 can be set to a T shape to prevent the extension plate 15 from directly detaching from the extension groove 14, and a slide rail or other structure for the extension plate 15 to slide can also be set on the inner wall of the extension groove 14. This is a structure that can be arranged by technical personnel in this field according to actual conditions and will not be elaborated here.

[0045] Furthermore, a rotating piece 17 is provided in the ventilation slot 13, and a rotating rod is fixedly provided in the middle of the rotating piece 17, and the rotating rod is rotatably connected to the inner wall of the ventilation slot 13. The rotating piece 17 is located below the extending slot 14, and a first intercepting column 18 and a second intercepting column 19 are fixedly provided inside the ventilation slot 13, and the first intercepting column 18 and the second intercepting column 19 are respectively located on both sides of the rotating piece 17; when the rotating piece 17 is in contact with the first intercepting column 18 or the second intercepting column 19, it is in an inclined state, and can smoothly guide the wind force entering the ventilation slot 13 to the bottom of the extending plate 15 and push the extending plate 15 to slide upward.

[0046] Furthermore, ventilation gaps are left between the upper and lower ends of the inclined rotating piece 17 and the upper and lower inner walls of the ventilation slot 13 respectively. When the wind pushes the rotating piece 17 to rotate, the wind passes through the tiny ventilation gap and causes the rotating piece 17 to vibrate, thereby generating sound, playing the role of a wind whistle, having the function of driving away birds, preventing birds from landing on the insulator to rest or build nests, and making it less likely for stains such as bird droppings to form on the surface of the insulator, thereby making it more practical.

[0047] In order to enable the cleaning plate 31 to slide smoothly, a groove 34 is opened at the bottom end of the cleaning plate 31 close to the rotating ring 6, and a ball 16 is movably embedded in the groove 34. The ball 16 is movably fitted to the upper surface of the corresponding first umbrella skirt 2 or the second umbrella skirt 3. The cleaning plate 31 contacts the corresponding first umbrella skirt 2 or the second umbrella skirt 3 by means of the ball 16 and slides smoothly.

[0048] In the present invention, when the cleaning plate 31 rotates, it also has the purpose of accelerating the rainwater on the surface of the corresponding first umbrella skirt 2 or the second umbrella skirt 3 to flow out from the notch 5, thereby preventing excessive accumulation of rainwater on the surface of the first umbrella skirt 2 or the second umbrella skirt 3 and directly flowing out from the outer edge of the protruding end 4.

[0049] One end of the cleaning plate 31 away from the rotating ring 6 extends out of the corresponding outer edges of the first umbrella skirt 2 and the second umbrella skirt 3, and the extended ends of the cleaning plate 31 are connected to the wind plate 21. The wind plate 21 is also driven by wind force, so that the cleaning plate 31 rotates. The surface of the wind plate 21 is a reflective surface. When the wind plate 21 rotates, the principle of reflecting light is used to make birds think that the area has been occupied or poses a risk, thereby preventing birds from staying near the insulator, effectively protecting the insulator from bird intrusion.

[0050] Furthermore, two magnetic blocks 35 are provided at the upper and lower ends of the wind plate 21, and the two magnetic blocks 35 are respectively located on the two side surfaces of the wind plate 21, and the upper and lower adjacent wind plates 21 are staggered in the height direction, and the height of the bottom surface of the lower end of the upper wind plate 21 is lower than the height of the upper end surface of the lower wind plate 21, and the magnetic block 35 at the lower end of the upper wind plate 21 repels each other with the magnetic block 35 corresponding to the upper end of the lower wind plate 21; during operation, due to the repulsion between the two magnetic blocks 25, the upper and lower adjacent wind plates 21 can always be staggered, so as to avoid the wind plates 21 at the upper and lower positions colliding with each other when the wind plates 21 rotate; and it also avoids the rainwater flowing along the wind plates 21 from forming continuous rain columns.

[0051] In order to further enhance the self-cleaning effect of the insulator itself, a fixed plate 28 is fixed at the top of the rotating ring 6, and an embedded groove 32 is provided on the side of the fixed plate 28 close to the core rod 1, and a spring 33 is fixed in the embedded groove 32, and a collision ball 29 is fixed on one side of the spring 33, and the collision ball 29 extends out of the embedded groove, and a fixed ball 30 is fixed on the outside of the core rod 1, and the collision ball 29 and the fixed ball 30 are arranged corresponding to each other; when the rotating ring 6 rotates, the collision ball 29 will intermittently hit the fixed ball 30, and due to the hitting effect, the cleaning plate 31, the first umbrella skirt 2 or the second umbrella skirt 3 will form a certain degree of vibration, which is conducive to the removal of dust; and when there is rainwater on the surface of the first umbrella skirt 2 or the second umbrella skirt 3, it can promote the rainwater to flow along the upper surface of the first umbrella skirt 2 or the second umbrella skirt 3 to its outer edge.

[0052] The protruding end 4 is usually made of rubber material, but can also be made of plastic, ceramic or other materials. The protruding end 4 is installed and fixed on the outer edge of the corresponding first umbrella skirt 2 or the second umbrella skirt 3 by sleeve or bonding. The detachable connection is convenient for direct application on existing insulators without replacing the insulator as a whole. It has broad application prospects and is easy to disassemble and replace.

[0053] Among them, a sliding groove is provided at the bottom end of the cleaning plate 31 for the protruding end 4 to slide through. The cross-section of the sliding groove is a three-quarter circular groove structure. The protruding end 4 also serves as a guide rail when the cleaning plate 31 rotates, thereby avoiding the end of the cleaning plate 31 from warping upward and causing poor cleaning effect, thereby increasing the service life.

[0054] As an existing conventional arrangement, in the present invention, a top seat 22 is fixed at the top of the mandrel 1, and fixing columns 23 are fixed on both sides of the top of the top seat 22. A lower pressing block 25 is slidably sleeved on the outer sides of the two fixing columns 23. A semicircular sleeve 24 is fixed on the opposite side of the lower pressing block 25 and the top seat 22. The two semicircular sleeves 24 are combined into a circle. The top ends of the outer sides of the two fixing columns 23 are threadedly matched with nuts 26. The two nuts 26 are pressed tightly on the upper surface of the lower pressing block 25. A protective cover 27 is engaged with the outer side of the top seat 22, so that the cable can be placed inside the two semicircular sleeves 24, and the two semicircular sleeves 24 are used to support the cable, and the nuts 26 are used to press the lower pressing block 25 so that the lower pressing block 25 can press and fix the cable to prevent the cable from moving. At the same time, after the cable is fixed, the protective cover 27 can be engaged with the outer side of the cable, and the protective cover 27 can protect the lower pressing block 25 and the two semicircular sleeves 24 to reduce the erosion of rainwater.

[0055] A steel foot 8 is fixed to the bottom end of the core rod 1, and a plurality of connecting rods 9 are fixed to the outside of the steel foot 8. A base 10 is sleeved on the outer circle of the steel foot 8, and a plurality of matching blocks 11 are fixed inside the base 10. The plurality of matching blocks 11 correspond one to one with the plurality of connecting rods 9. A slot 12 is provided on the side of the matching block 11 close to the center of the base 10, and the end of the connecting rod 9 is inserted into the corresponding slot 12, and the connecting rod 9 and the slot 12 are fixed by cement glue. The core rod 1 can be fixed to the inside of the base 10 by the steel foot 8, and the connecting rod 9 on the steel foot 8 can be inserted into the corresponding slot 12. On the one hand, it can facilitate the docking installation between the steel foot 8 and the base 10, and can play a certain supporting and fixing role before cement glue. At the same time, during cement glue, the plurality of connecting rods 9 can increase the contact area with the cement, so that after the glue is completed, the strength of the connection is increased, and the insulation can be increased due to the use of cement glue.
