Description

Technical Field

[0001] The invention relates to the technical field of transformer processing, in particular to an auxiliary processing device for external insulation of a transformer grading ball. Background Art

[0002] In the Shantou immersion transformer with voltage above the rated voltage, the electric field distribution is extremely uneven. Therefore, it is necessary to place a metal shielding device with a large curvature radius and electrically connected to the outlet at the end of the outlet bushing, commonly known as a voltage-equalizing ball, to make the electric field distribution around it tend to be uniform. The voltage-equalizing ball is a hollow metal sphere made of copper or aluminum with openings at both ends. The voltage-equalizing ball is usually spherical or nearly spherical, and some are designed to be cylindrical. It is generally composed of a body, a support, a connector, and other parts. The voltage-equalizing ball is generally made of metal materials such as steel and copper to ensure that it has good conductivity and mechanical strength. At the same time, in order to meet the insulation performance requirements, the surface of the voltage-equalizing ball needs to be insulated. The common method is to apply insulating paper pulp on the surface of the voltage-equalizing ball.

[0003] When applying insulating slurry to the transformer equalizing ball, it needs to be tightly fixed. However, the surface of the transformer equalizing ball is relatively smooth, and a large pressure needs to be applied when fixing it. As a result, it is difficult to control the force of the fixed plate made of hard material when pushing the transformer equalizing ball, resulting in a certain wear on the surface of the transformer equalizing ball. Therefore, we propose an auxiliary processing device for the external insulation of the transformer equalizing ball. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an auxiliary processing device for the external insulation of the transformer equalizing ball, comprising a base, the top of the base is fixedly connected to an electric slide rail, the top of the electric slide rail is slidably connected to an adjustment mechanism, the top of the base is fixedly connected to a curved fixing rod, the end of the curved fixing rod away from the base is fixedly connected to an arc frame, the inner side of the arc frame is fixedly connected to a scraping mechanism, the top of the electric slide rail is fixedly connected to a cleaning mechanism, the top of the base is fixedly connected to a material storage box, the top of the material storage box is connected to a high-pressure suction pump, the top of the high-pressure suction pump is connected to an arc-shaped connecting pipe, and the end of the arc-shaped connecting pipe away from the high-pressure suction pump is connected to a spray plate;

[0005] The adjusting mechanism comprises a frame-shaped slide plate, the inner wall of the frame slide plate is fixedly connected to the driving motor, the driving shaft of the driving motor passes through the frame slide plate and is fixedly connected to the threaded long rod, the top of the threaded long rod is fixedly connected to the top round block, and the threaded long rod is threadedly matched with the thread of the threaded sleeve to adjust the position of the transformer equalizing ball from the scraping mechanism to adjust the thickness of the mud wrapping, so as to prevent the transformer equalizing ball from being required to be manually trimmed at all times when slurry is applied to the transformer equalizing ball, which is time-consuming and laborious. By arranging a top round block on the top of the threaded long rod, the threaded sleeve is resisted and limited to prevent the fixed transformer equalizing ball from moving up to a position where it is out of engagement with the thread of the threaded long rod as the threaded sleeve moves, thereby preventing it from falling off and causing safety hazards. The outer side of the threaded long rod is sleeved and threadedly connected to the threaded sleeve. One side of the threaded sleeve is fixedly connected to an annular electric slide rail, and the inner side of the annular electric slide rail is rotatably connected to a curved ring plate, and one side of the curved ring plate is fixedly connected to a receiving ring, and the receiving ring is fixedly connected to an annular plastic pad on the side away from the curved ring plate. By arranging an annular plastic pad made of elastic rubber material on one side of the receiving ring and directly contacting the surface of the transformer equalizing ball, it is prevented that the receiving ring made of hard material is difficult to control the force when pushing the transformer equalizing ball, resulting in a certain wear on the surface of the transformer equalizing ball. By arranging an annular plastic pad on one side of the receiving ring to fit and squeeze the surface of the transformer equalizing ball, the inner area of the curved ring plate is blocked, and the contact area between the hard material sleeve and the transformer equalizing ball is too small, which prevents mud from easily leaking into the inner side of the curved ring plate when driving it to rotate, causing accumulation and difficulty in handling.

[0006] There are two electric slide rails, and the two electric slide rails are distributed on the base; there are multiple adjustment mechanisms, and the multiple adjustment mechanisms are distributed in the areas on both sides of the cleaning mechanism on the electric slide rail;

[0007] There are two curved fixing rods, and the two curved fixing rods are respectively distributed on the base between the material storage box and the electric slide rail. There are two material storage boxes, and the two material storage boxes are respectively distributed on the base in the area on one side of the curved fixing rod away from the electric slide rail. There are two arc-shaped connecting pipes, and the two arc-shaped connecting pipes are distributed on both sides of the spray plate.

[0008] The bottom of the frame-shaped slide is slidably connected to the top of the electric slide rail, and a plurality of the frame-shaped slides are provided, and the plurality of frame-shaped slides are respectively on the electric slide rail;

[0009] The bottom of the threaded long rod is rotatably connected to the top of the frame-shaped slide plate through a rotating bolt. Two threaded sleeves are provided, and the two threaded sleeves are distributed on the outer side of the annular slide rail near the threaded long rod.

[0010] Furthermore, the scraping mechanism includes a V-shaped arc plate, which is used to scrape and trim the slurries of different thicknesses on the surface of the transformer equalizing ball, so as to prevent the slurry coated on the surface of the transformer equalizing ball from having different thicknesses or incomplete coating, which affects the processing effect of the transformer equalizing ball. A V-shaped arc hole is provided at the bottom of the V-shaped arc plate, and the V-shaped arc hole is provided on the inner side of the V-shaped arc plate to facilitate the scraped slurry to fall down and discharge, so as to prevent a part of the slurry scraped by the V-shaped arc plate from accumulating on the inner side of the V-shaped arc plate and being difficult to discharge for a long time, which affects the subsequent trimming effect. The outer side of the V-shaped arc plate is fixedly connected with a side inclined arc plate, which is formed on the outer side of the V-shaped arc plate. A side inclined arc plate is provided to guide the slurry scraped to the outside by the V-shaped arc plate to the central area, so as to prevent the slurry from being scattered around when being scraped to the outside as the transformer equalizing ball rotates all the time and is difficult to be handled centrally. A bottom-opened arc hole is provided at the bottom of the side inclined arc plate. By providing the bottom-opened arc hole at the bottom of the side inclined arc plate, the slurry sliding to the central area can be easily discharged in time, so as to prevent the scraped slurry from continuously accumulating between the side inclined arc plate and the outer side of the V-shaped arc plate when a large amount of slurry is scraped away, so that it is easy to overflow to the outside and difficult to handle. The outer side of the side inclined arc plate is fixedly connected to the inner side of the arc frame. Two side inclined arc plates are provided, and the two side inclined arc plates are respectively distributed on the outer side of the V-shaped arc plate.

[0011] Furthermore, the cleaning mechanism includes a horizontal slide, both sides of which are fixedly connected with concave side plates, and the concave side plates are arranged on both sides of the horizontal slide to cover and protect the top area of the electric slide located on both sides of the horizontal slide, to prevent a part of the slurry from accumulating in the area close to the electric slide and overflowing onto the electric slide when the slurry is pushed for a long time, and the bottom of the horizontal slide is fixedly connected with a bottom scraper, and the bottom scraper is arranged at the bottom of the horizontal slide to push the fallen slurry to a position close to the edge of the base for easy processing, to prevent the fallen slurry from being scattered all over the top of the base and difficult to collect and process it uniformly, and the two sides of the horizontal slide are fixedly connected with side concave rods, and the bottom of the side concave rods is fixedly connected with an inclined push plate, An inclined push plate is provided at the bottom of the concave rod to guide the pushed slurry to the middle area, preventing too much slurry near the electric slide rail on the base from accumulating easily and overflowing onto the electric slide rail during cleaning. By providing multiple inclined push plates at the bottom of the side concave rod and keeping a certain distance from the electric slide rail, it is convenient for the slurry to pass through, preventing the slurry from accumulating in the area between the multiple inclined push plates and the electric slide rail, and the inclined push plates move at all times and are difficult to be pushed to the area near the edge of the base for unified processing. The bottom of the horizontal slide is slidably connected to the top of the electric slide rail, and the bottom of the concave side plate is slidably connected to the top of the electric slide rail. There are multiple concave side plates, and the multiple concave side plates are distributed on both sides of the horizontal slide.

[0012] The present invention provides an auxiliary processing device for the external insulation of a transformer grading ball. It has the following beneficial effects:

[0013] 1. The auxiliary processing device for the external insulation of the transformer equalizing ball is configured to provide an annular plastic pad made of elastic rubber material on one side of the receiving ring in direct contact with the surface of the transformer equalizing ball to prevent the receiving ring made of hard material from being difficult to control the force when pushing the transformer equalizing ball, resulting in a certain wear on the surface of the transformer equalizing ball. The slurry of different thicknesses on the surface of the transformer equalizing ball is scraped and trimmed by a V-shaped arc plate to prevent the slurry coated on the surface of the transformer equalizing ball from having different thicknesses or incomplete coating, which affects the processing effect of the transformer equalizing ball. A bottom scraper is provided at the bottom of the horizontal slide to push the fallen slurry to a position close to the edge of the base for easy processing, to prevent the fallen slurry from being scattered all over the top of the base and difficult to collect and process.

[0014] 2. The auxiliary processing device for the external insulation of the transformer grading ball is provided with an adjustment mechanism. A top round block is provided on the top of the threaded long rod to resist and limit the threaded sleeve, thereby preventing the fixed transformer grading ball from moving up to a position where it is out of engagement with the thread of the threaded long rod as the threaded sleeve moves, thereby preventing it from falling off and causing safety hazards. An annular plastic pad made of elastic rubber material is provided on one side of the receiving ring to directly contact the surface of the transformer grading ball, thereby preventing the receiving ring made of hard material from being difficult to control the force when pushing the transformer grading ball, thereby preventing the surface of the transformer grading ball from being worn to a certain extent. By setting an annular plastic pad on one side of the receiving ring to fit and squeeze the surface of the transformer equalizing ball to seal the inner area of the curved ring plate, it is prevented that the contact area between the hard material ring and the transformer equalizing ball is too small, and the mud material is easily leaked to the inside of the curved ring plate when driving it to rotate and accumulates and is difficult to handle. The position of the transformer equalizing ball from the scraping mechanism is adjusted by the threaded long rod and the threaded sleeve block to adjust the thickness of the mud wrapping, so as to avoid the need for manual trimming of the mud wrapping thickness when applying slurry to the transformer equalizing ball. It is time-consuming and laborious.

[0015] 3. The auxiliary processing device for the external insulation of the transformer equalizing ball is provided with a scraping mechanism, which scrapes and trims the slurries of different thicknesses on the surface of the transformer equalizing ball through a V-shaped arc plate, so as to prevent the slurry coated on the surface of the transformer equalizing ball from being unevenly coated or incompletely coated, which affects the processing effect of the transformer equalizing ball. A V-shaped arc hole is provided on the inner side of the V-shaped arc plate to facilitate the scraped slurry to fall down and discharge, so as to prevent a part of the slurry scraped by the V-shaped arc plate from accumulating on the inner side of the V-shaped arc plate and being difficult to discharge for a long time, which affects the subsequent trimming processing effect. A side inclined arc plate is provided on the outer side of the V-shaped arc plate to guide the slurry scraped to the outside by the V-shaped arc plate to the central area, so as to prevent the slurry from being scattered around when being scraped to the outside as the transformer equalizing ball rotates all the time and being difficult to be processed in a centralized manner. A bottom-opening arc hole is provided at the bottom of the side inclined arc plate to facilitate the slurry sliding toward the central area to fall and discharge in time, so as to prevent the scraped slurry from accumulating between the side inclined arc plate and the outer side of the V-shaped arc plate when a large amount of slurry is scraped, which is easy to overflow to the outside and difficult to process.

[0016] 4. The auxiliary processing device for the external insulation of the transformer equalizing ball is provided with a cleaning mechanism, which guides the pushed slurry to the middle area by arranging an inclined push plate at the bottom of the side concave rod, thereby preventing the slurry on the base from accumulating too much near the electric slide rail and overflowing onto the electric slide rail during cleaning. By arranging multiple inclined push plates at the bottom of the side concave rod and at a distance from the electric slide rail to facilitate the passage of slurry, the slurry is prevented from accumulating in the area between the multiple inclined push plates and the electric slide rail, and the inclined push plates move at all times and are difficult to be pushed to the area near the edge of the base for unified treatment. By arranging a bottom scraper at the bottom of the horizontal slide plate, the fallen slurry is uniformly pushed to a position near the edge of the base for easy treatment, and the fallen slurry is prevented from being scattered all over the top of the base and difficult to be collected and treated uniformly. By arranging concave side plates on both sides of the horizontal slide plate, the area on the top of the electric slide rail located on both sides of the horizontal slide plate is covered and protected, thereby preventing a part of the slurry from accumulating in the area near the electric slide rail and overflowing onto the electric slide rail when the slurry is pushed for a long time.

[0031] The bottom of the frame-shaped slide 301 is slidably connected to the top of the electric slide rail 2. There are multiple frame-shaped slides 301, and the multiple frame-shaped slides 301 are respectively on the electric slide rail 2;

[0032] The bottom of the threaded long rod 303 is rotatably connected to the top of the frame-shaped slide plate 301 by a rotating bolt, and the threaded sleeve block 305 is provided with two, and the two threaded sleeve blocks 305 are distributed on the outer side of the annular slide rail near the position of the threaded long rod 303. When in use, the transformer equalizing ball to be processed is placed on the scraping mechanism 6 on the inner side of the two arc frames 5. At this time, the adjusting mechanism 3 is adjusted to the height that the center of the circle is aligned with the center of the transformer equalizing ball, and then the adjusting mechanism 3 on both sides of the transformer equalizing ball is driven by the electric slide rail 2 to fix it in the sleeve type.

At the same time, the slurry is pumped into the spray plate 11 by the high-pressure suction pump 9 and sprayed on the surface of the transformer equalizing ball. The transformer equalizing ball is driven up and down by the adjusting mechanism 3 to adjust the position of the distance scraping mechanism 6 to control the scraping mechanism 6 to process the thickness of the transformer equalizing ball surface. The excess slurry scraped off by the scraping mechanism 6 falls on the base 1. At this time, the cleaning mechanism 7 can be driven by the electric slide rail 2 to discharge the accumulated slurry on the base 1 to both sides for subsequent processing;

[0033] After the transformer equalizing ball is placed on the scraping mechanism 6 on the inner side of the two arc frames 5, the driving motor 302 is started to drive the threaded long rod 303 to rotate. When the threaded long rod 303 rotates, the annular electric slide 306, the curved ring plate 307, the receiving ring 308 and the annular plastic pad 309 are driven down to the same height position as the center of the circle of the transformer equalizing ball by cooperating with the thread of the threaded sleeve 305.

An annular plastic pad 309 made of elastic rubber material is provided on one side of the receiving ring 308 to directly contact the surface of the transformer equalizing ball. By providing an annular plastic pad 309 on one side of the receiving ring 308 to engage in a close-fitting extrusion contact with the surface of the transformer equalizing ball, the inner area of the curved ring plate 307 is sealed. After fixation, the threaded long rod 303 drives the clamped transformer equalizing ball to move up to a position where it does not contact the scraping mechanism 6. The threaded long rod 303 and the threaded sleeve block 305 are used to adjust the position of the transformer equalizing ball from the scraping mechanism 6 to adjust the thickness of the mud wrapping. At this time, the annular electric slide rail 306 drives the curved ring plate 307 and the fixed transformer equalizing ball to rotate to cooperate with the spray plate 11 to spray and apply insulating paper pulp to various parts of the surface of the transformer equalizing ball.

[0034] See also Figures 1-8 The present invention provides an auxiliary processing device for the external insulation of a transformer grading ball: the scraping mechanism 6 includes a V-shaped arc plate 601, a V-shaped arc hole 602 is opened at the bottom of the V-shaped arc plate 601, a side oblique arc plate 603 is fixedly connected to the outer side of the V-shaped arc plate 601, a bottom-opening arc hole 604 is opened at the bottom of the side oblique arc plate 603, the outer side of the side oblique arc plate 603 is fixedly connected to the inner side of the arc frame 5, two side oblique arc plates 603 are provided, and the two side oblique arc plates 603 are respectively distributed on the outer side of the V-shaped arc plate 601;

[0035] The cleaning mechanism 7 includes a horizontal slide 701, both sides of the horizontal slide 701 are fixedly connected with concave side plates 702, the bottom of the horizontal slide 701 is fixedly connected with a bottom scraper 703, both sides of the horizontal slide 701 are fixedly connected with side concave rods 704, the bottom of the side concave rods 704 are fixedly connected with an inclined push plate 705, the bottom of the horizontal slide 701 is slidably connected to the top of the electric slide rail 2, the bottom of the concave side plate 702 is slidably connected to the top of the electric slide rail 2, a plurality of concave side plates 702 are provided, and the plurality of concave side plates 702 are distributed on both sides of the horizontal slide 701, a plurality of inclined push plates 705 are provided, and the plurality of inclined push plates 705 are symmetrically distributed on the sides. The bottom of the concave rod 704 is placed. When in use, the threaded long rod 303 and the threaded sleeve block 305 are used to adjust the transformer equalizing ball to a suitable distance from the V-shaped arc plate 601. The V-shaped arc plate 601 contacts the slurry on the surface of the rotating transformer equalizing ball and scrapes it. The V-shaped arc plate 601 is used to scrape and trim the slurry of different thicknesses on the surface of the transformer equalizing ball. A V-shaped arc hole 602 is opened on the inner side of the V-shaped arc plate 601 to facilitate the scraped slurry to fall downward and discharge. The slurry scraped to the outside by the V-shaped arc plate 601 falls on the side inclined arc plate 603 and slides in the direction of the V-shaped arc plate 601 through the inclined surface of the side inclined arc plate 603 and then opens an arc from the bottom. The slurry falls downward from the hole 604 onto the base 1, and the slurry scraped to the outside by the V-shaped arc plate 601 is guided to the central area by arranging a side inclined arc plate 603 on the outside of the V-shaped arc plate 601. The slurry is easily discharged in time by opening a bottom arc hole 604 at the bottom of the side inclined arc plate 603. When the transformer equalizing ball is processed and no longer sprayed with slurry, the horizontal slide 701 can be driven by the electric slide rail 2 to drive the concave side plate 702, the bottom scraper 703, the side concave rod 704 and the inclined push plate 705 to move together. When the horizontal slide 701 moves, the inclined push plate 705 contacts the slurry on the base 1 and pushes it along the inclined surface of the inclined push plate 705. The slurry moves in the middle area by arranging an inclined push plate 705 at the bottom of the side concave rod 704 to guide the pushed slurry to the middle area. By arranging multiple inclined push plates 705 at the bottom of the side concave rod 704 and at a distance from the electric slide rail 2, it is convenient for the slurry to pass through. The slurry pushed to the middle area by the inclined push plate 705 continues to be pushed by the bottom scraper 703 and gradually moves toward the edge of the base 1. By arranging a bottom scraper 703 at the bottom of the horizontal slide plate 701, the fallen slurry is uniformly pushed to a position close to the edge of the base 1 for easy processing. By arranging concave side plates 702 on both sides of the horizontal slide plate 701, the area on the top of the electric slide rail 2 on both sides of the horizontal slide plate 701 is covered and protected.

[0036] When the present invention is in operation, the transformer equalizing ball to be processed is placed on the scraping mechanism 6 on the inner side of the two arc frames 5. At this time, the adjusting mechanism 3 is adjusted to a height where the center of the circle is aligned with the center of the transformer equalizing ball, and then the adjusting mechanisms 3 on both sides of the transformer equalizing ball are driven by the electric slide 2 to fix it in a sleeve-type internal clamp. After the transformer equalizing ball is fixed, it can be driven to rotate by the adjusting mechanism 3. At the same time, the slurry is pumped into the spray plate 11 by the high-pressure suction pump 9 and sprayed on the surface of the transformer equalizing ball. The transformer equalizing ball is driven up and down by the adjusting mechanism 3 to adjust the position of the distance from the scraping mechanism 6 to control the scraping mechanism 6 to process the surface thickness of the transformer equalizing ball. The excess slurry scraped off by the scraping mechanism 6 falls on the base 1. At this time, the cleaning mechanism 7 can be driven by the electric slide 2 to discharge the accumulated slurry on the base 1 to both sides for subsequent processing.

[0037] After the transformer equalizing ball is placed on the scraping mechanism 6 on the inner side of the two arc frames 5, the driving motor 302 is started to drive the threaded long rod 303 to rotate. When the threaded long rod 303 rotates, the annular electric slide 306, the curved ring plate 307, the receiving ring 308 and the annular plastic pad 309 are driven downward by the threaded cooperation with the threaded sleeve 305 to move the center of the circle to the same height position as the center of the transformer equalizing ball. The threaded sleeve 305 is resisted and limited by setting a top circle block 304 on the top of the threaded long rod 303. At this time, the frame-shaped slide 301 can be driven by the electric slide 2 to drive the adjustment mechanism 3 to move as a whole toward the transformer equalizing ball. The annular plastic pad 309 is set on the surface of the transformer equalizing ball as the frame-shaped slide 301 moves and is tightened by the receiving ring 308 The push-type clamping fixation is performed by arranging an annular plastic pad 309 made of elastic rubber material on one side of the receiving ring 308 to directly contact the surface of the transformer equalizing ball. The inner area of the curved ring plate 307 is sealed by arranging an annular plastic pad 309 on one side of the receiving ring 308 to fit and squeeze the surface of the transformer equalizing ball. After the fixation is completed, the threaded long rod 303 drives the clamped transformer equalizing ball to move up to a position where it does not contact the scraping mechanism 6. The threaded long rod 303 and the threaded sleeve block 305 are used to adjust the position of the transformer equalizing ball from the scraping mechanism 6 to adjust the thickness of the mud wrap. At this time, the annular electric slide rail 306 drives the curved ring plate 307 and the fixed transformer equalizing ball to rotate to cooperate with the spray plate. 11. Spraying and coating of insulating paper pulp on the surface of the transformer grading ball is performed. When the transformer grading ball is moved to a suitable distance from the V-shaped arc plate 601 by adjusting the threaded long rod 303 and the threaded sleeve 305, the V-shaped arc plate 601 contacts the slurry on the surface of the rotating transformer grading ball and scrapes it. The V-shaped arc plate 601 is used to scrape and trim the slurry of different thicknesses on the surface of the transformer grading ball. A V-shaped arc hole 602 is provided on the inner side of the V-shaped arc plate 601 to facilitate the scraped slurry to fall downward and be discharged. The slurry scraped to the outside by the V-shaped arc plate 601 falls on the side inclined arc plate 603 and slides in the direction of the V-shaped arc plate 601 through the inclined surface of the side inclined arc plate 603, and then falls downward from the arc hole 604 at the bottom onto the base 1. By arranging a side inclined arc plate 603 on the outside of the V-shaped arc plate 601, the slurry scraped to the outside by the V-shaped arc plate 601 is guided to the central area, and by providing a bottom open arc hole 604 at the bottom of the side inclined arc plate 603, the slurry sliding to the central area can be discharged in time. When the transformer equalizing ball processing is completed and the slurry spraying is no longer performed, the horizontal slide 701 can be driven by the electric slide rail 2 to drive the concave side plate 702, the bottom scraper 703, the side concave rod 704 and the inclined push plate 705 to move together. When the horizontal slide 701 moves, the inclined push plate 705 contacts the slurry on the base 1 and pushes it to move along the inclined surface of the inclined push plate 705 to the middle area. By arranging an inclined push plate 705 at the bottom of the side concave rod 704, the pushed slurry is guided to the middle area.By installing multiple inclined push plates 705 at the bottom of the side concave rods 704 and at a distance from the electric slide rail 2, the slurry can pass through more easily. The inclined push plates 705 push the slurry to the middle area, which is then pushed by the bottom scraper 703 and gradually moves toward the edge of the base 1. By installing a bottom scraper 703 at the bottom of the horizontal slide 701, the fallen slurry is uniformly pushed to a position near the edge of the base 1 for easy handling. By installing concave side plates 702 on both sides of the horizontal slide 701, the area on the top of the electric slide rail 2 located on both sides of the horizontal slide 701 is covered and protected.
