Description

Technical Field

[0001] This invention relates to the field of insulator technology, and in particular to an assembled porcelain insulator. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although different types of insulators vary considerably in structure and appearance, they all consist of two main parts: insulating components and connecting hardware.

[0003] Porcelain insulators are crucial components in power transmission and transformation systems, typically assembled from multiple units. Current assembly methods involve aligning the lower flange of the upper insulator with the upper flange of the lower insulator, ensuring the mounting holes on both flanges correspond, and then tightening them with fasteners. To enhance the flange's stability, adhesive is usually applied to the mating surfaces. When the series-connected insulators need to be disassembled for maintenance or other reasons, in addition to loosening the fasteners, the adhesive layer must be removed to separate the flanges. This adhesive removal process is time-consuming, labor-intensive, increases the workload of operators, and can easily damage the flanges and insulators, increasing equipment operating costs.

[0004] Therefore, it is necessary to propose an assembled porcelain insulator to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an assembled porcelain insulator to solve the problems mentioned in the background art. In existing porcelain insulators, the lower flange of the upper insulator is aligned with the upper flange of the lower insulator, and the mounting holes on the two flanges are aligned before fastening with fasteners. Furthermore, to improve the firmness between the flanges, adhesive is usually applied to the mating surfaces of the two flanges. When the insulator needs to be disassembled for maintenance or other reasons, in addition to loosening the fasteners, the adhesive layer must be removed to separate the two flanges. This adhesive removal process is not only time-consuming and labor-intensive, increasing the workload of operators, but also easily damages the flanges and insulators, increasing equipment operating costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an assembled porcelain insulator, comprising a first core post, a second core post disposed below the first core post, the second core post being coaxially disposed with the first core post, a first circular groove being formed at the bottom of the first core post, a ball groove being formed inside the first core post, the ball groove communicating with the first circular groove, a first vertical groove being formed at the bottom of the side wall of the second core post, the first vertical groove communicating with the first circular groove, a first locking groove being formed at the top of the first vertical groove, the first locking groove communicating with the ball groove, a rotating ball being rotatably connected inside the ball groove, a connecting rod being disposed inside the first circular groove, the connecting rod being fixedly connected to the rotating ball, the end of the connecting rod away from the rotating ball being fixedly connected to the second core post, a limit component being disposed on the first core post, and a buffer component being disposed inside the first circular groove.

[0008] Preferably, the limiting component further includes an annular groove, a rotating ring, a retaining plate, and a second retaining groove. The second retaining groove is formed on the side wall of the second vertical groove and is located at the bottom of the second vertical groove. The annular groove is formed on the outer wall of the round rod. The rotating ring is rotatably connected to the inside of the annular groove. The retaining plate is fixedly connected to the outer ring of the rotating ring and cooperates with the second retaining groove.

[0009] Preferably, a ball bearing is movably embedded in the outer wall of the round rod, and the ball bearing slides against the outer wall of the rotating ball.

[0010] Preferably, the buffer assembly is configured as three groups, and the three groups of buffer assemblies are distributed in a circular array around the connecting rod.

[0011] Preferably, the buffer assembly includes a cylinder, a second spring, and a sliding rod. The cylinder is fixedly connected to the inner wall of the first circular groove, the sliding rod is slidably connected to one end of the cylinder near the connecting rod, the second spring is located inside the cylinder, one end of the second spring is fixedly connected to the sliding rod, and the other end of the second spring is fixedly connected to the inner wall of the cylinder.

[0012] Preferably, the buffer assembly further includes an arc plate, which is fixedly connected to the end of the slide rod away from the cylinder. The side of the arc plate facing the connecting rod is a concave surface, and the concave surface of the arc plate abuts against the connecting rod.

[0015] Preferably, a second metal cap is fixedly connected to the end of the second core post away from the first core post, and a second connector is fixedly connected to the second metal cap.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. After the ball is installed inside the ball groove, release the locking plate. The return force of the first spring causes the round rod to slide down and return to its original position. Adjust the locking plate to align it with the position of the second locking groove. Rotate the locking plate towards the second locking groove. The locking plate engages with the inside of the second locking groove, thereby positioning the round rod. The round rod prevents the ball from coming out of the ball groove, improving the stability of the connection between the first core and the second core.

[0018] 2. When the first core column and the second core column deflect relative to each other, the connecting rod slides inside the cylinder by pressing the slide bar through the arc plate, and the second spring provides force relief and buffering, thereby improving the buffering performance during the swinging process of the first core column and the second core column.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides, for example Figures 1-6 The illustrated assembled porcelain insulator includes a first core post 1, a second core post 3 disposed below the first core post 1, and the second core post 3 being coaxially arranged with the first core post 1. A first shed sleeve 2 is fixedly connected to the first core post 1, and a second shed sleeve 4 is fixedly connected to the second core post 3.

[0028] The bottom of the first core post 1 has a first circular groove 7, and the inside of the first core post 1 has a ball groove 5, which communicates with the first circular groove 7. The bottom of the side wall of the second core post 3 has a first vertical groove 8, which communicates with the first circular groove 7. The top of the first vertical groove 8 has a first locking groove 6, which communicates with the ball groove 5.

[0029] The ball groove 5 is rotatably connected to a rotating ball 9. The first circular groove 7 is provided with a connecting rod 10, which is fixedly connected to the rotating ball 9. The end of the connecting rod 10 away from the rotating ball 9 is fixedly connected to the second core column 3.

[0030] During operation, the rotating ball 9 is inserted into the ball groove 5 through the first slot 6, while the connecting rod 10 is inserted into the first circular groove 7 through the first vertical groove 8.

[0031] To prevent the rotating ball 9 from coming out of the ball groove 5, a limit component is provided on the first core column 1.

[0032] In a specific configuration, the limiting assembly includes a second circular groove 11, a second vertical groove 12, a round rod 13, and a first spring 14. The second circular groove 11 is formed at the top of the first slot 6, and the second vertical groove 12 is formed on the side wall of the first core post 1, communicating with the second circular groove 11. The round rod 13 is slidably connected inside the second circular groove 11, and the first spring 14 is located inside the second circular groove 11. One end of the first spring 14 is fixedly connected to the inner wall of the second circular groove 11, and the other end of the first spring 14 is fixedly connected to the round rod 13.

[0033] The limiting assembly also includes an annular groove 16, a rotating ring 17, a locking plate 18, and a second locking slot 19. The second locking slot 19 is formed on the side wall of the second vertical groove 12 and is located at the bottom of the second vertical groove 12. The annular groove 16 is formed on the outer wall of the round rod 13. The rotating ring 17 is rotatably connected to the inside of the annular groove 16. The locking plate 18 is fixedly connected to the outer ring of the rotating ring 17 and engages with the second locking slot 19. By rotating the locking plate 18 to align it with the position of the second vertical groove 12, and then pulling the locking plate 18 upward, it slides upward inside the second vertical groove 12, causing the round rod 13 to slide upward. By adjusting the locking plate 18 to align it with the position of the second locking slot 19, and rotating the locking plate 18 towards the second locking slot 19, the locking plate 18 engages with the inside of the second locking slot 19, thereby positioning the round rod 13.

[0034] When working, when it is necessary to assemble the second core column 3 and the first core column 1, rotate the clamping plate 18 so that it corresponds to the position of the second vertical groove 12, and then pull the clamping plate 18 upward so that it slides upward inside the second vertical groove 12, driving the round rod 13 to slide upward. The round rod 13 retracts inside the second round groove 11, without affecting the ball 9 passing through the first clamping groove 6 and inserting into the ball groove 5.

[0035] After the rotating ball 9 is installed inside the ball groove 5, the locking plate 18 is released. The reset force of the first spring 14 causes the round rod 13 to slide downwards and reset. The locking plate 18 is then adjusted to align with the position of the second locking groove 19. The locking plate 18 is rotated towards the second locking groove 19, and the locking plate 18 engages inside the second locking groove 19, thereby positioning the round rod 13. The round rod 13 prevents the rotating ball 9 from coming out of the ball groove 5, improving the stability of the connection between the first core post 1 and the second core post 3.

[0036] To avoid affecting the rotation of the ball 9 inside the first slot 6, a ball bearing 15 is movably embedded in the outer wall of the round rod 13, and the ball bearing 15 slides against the outer wall of the ball 9.

[0037] To improve the buffering performance of the first core column 1 and the second core column 3 during the swinging process, a buffer assembly is provided inside the first circular groove 7. The buffer assembly is set in three groups, and the three groups of buffer assemblies are distributed in a circular array around the connecting rod 10.

[0038] In a specific configuration, the buffer assembly includes a cylinder 20, a second spring 21, and a slide rod 22. The cylinder 20 is fixedly connected to the inner wall of the first circular groove 7, and the slide rod 22 is slidably connected to one end of the cylinder 20 near the connecting rod 10. The second spring 21 is located inside the cylinder 20, with one end fixedly connected to the slide rod 22 and the other end fixedly connected to the inner wall of the cylinder 20.

[0039] The buffer assembly also includes an arc plate 23, which is fixedly connected to the end of the slide rod 22 away from the cylinder 20. The side of the arc plate 23 facing the connecting rod 10 is a concave surface, which abuts against the connecting rod 10. Arc-shaped notches are provided at both ends of the side of the arc plate 23 facing away from the connecting rod 10. The connecting rod 10 slides inside the cylinder 20 by pressing the slide rod 22 against the arc plate 23, and the second spring 21 provides force relief and buffering.

[0040] In practical use, by manually moving the arc plate 23, the sliding rod 22 is pressed and slids inside the cylinder 20, so that the connecting rod 10 passes between two adjacent arc plates 23. At the same time, the restoring force of the second spring 21 causes the arc plate 23 to reset and press against the outer wall of the connecting rod 10.

[0041] When the first core column 1 and the second core column 3 deflect relative to each other, the connecting rod 10 presses the slide rod 22 through the arc plate 23 to slide inside the cylinder 20, and the second spring 21 performs force relief and buffering, improving the buffering performance of the first core column 1 and the second core column 3 during the swinging process.

[0042] A first metal cap 24 is fixedly connected to the end of the first core post 1 away from the second core post 3, and a first connector 25 is fixedly connected to the first metal cap 24. A second metal cap 26 is fixedly connected to the end of the second core post 3 away from the first core post 1, and a second connector 27 is fixedly connected to the second metal cap 26. In actual use, the porcelain insulator is connected to the external power structure through the first connector 25 and the second connector 27.
