Description

Technical Field

[0001] This utility model relates to a porcelain insulator for ultra-high voltage lines, belonging to the field of power equipment technology. Background Technology

[0002] Porcelain insulators are insulating devices made of electrical ceramics. They are mainly used in power systems between conductors at different potentials or between conductors and grounding components to withstand voltage and mechanical stress. Their surface is usually covered with porcelain glaze to improve mechanical strength, water resistance and smoothness. They are one of the most widely used types of insulators in power systems.

[0003] The existing patent number CN211858282U describes a porcelain insulator for ultra-high voltage lines. This device can effectively reduce the impact force generated by wind and heavy rain, preventing the insulator from falling off. The mounting base is fixed to the insulation body with screws, preventing the adhesive from losing its stickiness due to prolonged contact with rainwater, which would cause the mounting base to fall off the insulation body. However, in this device, the porcelain insulator is still inserted into the outer side of the inner central pole, just like in existing technologies. Although it can achieve horizontal limiting, the longitudinal limiting force is insufficient. Moreover, the porcelain insulator needs to be broken to be detached during disassembly, which cannot achieve quick disassembly and assembly. In addition, the bottom of this device is only fixed at a single point. Although a buffer mechanism is set, the single-point fixing support method is still not enough to ensure the installation stability of the porcelain insulator. Furthermore, the insertion and tightening of multiple bolts is slow, which is not convenient for the stable and quick installation of the mounting base at the bottom. Utility Model Content

[0004] The purpose of this invention is to provide a porcelain insulator for ultra-high voltage lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A porcelain insulator for ultra-high voltage lines includes a mounting base and an insulating body. The insulating body is located on the outer side of the upper end of the mounting base. A threaded shaft is rotatably connected to the middle position inside the mounting base. A square extrusion post is helically connected to the outer side of the threaded shaft. A triangular bearing block is slidably connected to the outer side of the square extrusion post. A limit buckle is fixedly connected to the outer side of the triangular bearing block. The limit buckle is slidably connected to both the mounting base and the insulating body. An insertion handle is rotatably connected to the middle position of the lower end of the mounting base. The insertion handle is fixedly connected to the threaded shaft. A mounting sleeve is slidably connected to the outer side of the insertion handle. A top support rod is rotatably connected to the outer side of the mounting sleeve. A pin is rotatably connected to the outer end of the top support rod. A lateral insertion post is slidably connected to the outer side of the pin. The lateral insertion post is fixedly connected to the mounting base.

[0007] Furthermore, the outer side of the square extrusion column is provided with an inclined top pressing surface, which is in contact with the inner side of the triangular bearing block.

[0008] Furthermore, a circular groove is provided on the inner sidewall of the insulating body, and the position and size of the circular groove correspond to the position and size of the limiting circular buckle.

[0009] Furthermore, a circular slot is provided at the upper end of the mounting base.

[0010] Furthermore, the front and rear side walls of the insertion handle are slidably connected with positioning buckles, and the positioning buckles are slidably connected with the mounting sleeve.

[0011] Furthermore, the lower end of the insertion handle is provided with a limiting plate, the lower end of the limiting plate is rotatably connected to a pull ring, the upper end of the limiting plate is fixedly connected to a pull rod, the pull rod is slidably connected to the insertion handle, the upper end of the pull rod is rotatably connected to a transmission rod, the transmission rod is rotatably connected to a positioning buckle, and the lower thin rod surface of the pull rod is covered with a spring.

[0012] Furthermore, rectangular slots are provided on both the front and rear sides of the inner wall of the mounting sleeve, and the position and size of the rectangular slots correspond to the position and size of the positioning buckles.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a tube on the upper side of the mounting base that can be inserted into the insulation body, achieving horizontal positioning of the insulation body. Rotating the insertion handle allows the threaded shaft to rotate, causing the square pressing column to move upwards. The inclined pressure surface then presses against the triangular bearing block, causing it to move the limiting buckle outwards and insert it into the circular slot inside the insulation body. This achieves vertical positioning of the insulation body. It allows for quick installation of the insulation body without bonding it to the internal metal rod, facilitating future replacement. The invention also utilizes an installation sleeve that covers the outside of the insertion handle, and the lateral insertion column... By passing through the holes in the mounting bracket and pushing the mounting sleeve upwards, the top support rod can drive the pin to continuously insert into the groove inside the side insertion post, thereby achieving rapid fixation of the mounting base and enabling multi-point fixation to ensure the installation stability of the mounting base. Finally, by pulling the pull ring, the limiting plate can drive the pull rod downwards, causing the transmission rod to drive the positioning buckle to move inwards. After releasing the pull ring, the spring extends, causing the pull rod to move upwards, thereby causing the transmission rod to drive the positioning buckle to move outwards, so that the positioning buckle can quickly position the mounting sleeve. At the same time, the mounting sleeve can limit the rotation angle of the insertion handle through the positioning buckle to prevent the threaded shaft from deflecting, ensuring that the overall installation is in a stable state.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A porcelain insulator for ultra-high voltage lines includes a mounting base 1 and an insulating body 2. The insulating body 2 is located on the outer side of the upper end of the mounting base 1. A threaded shaft 3 is rotatably connected to the middle position inside the mounting base 1. A square compression post 4 is spirally connected to the outer side of the threaded shaft 3. A triangular bearing block 5 is slidably connected to the outer side of the square compression post 4. A limiting buckle 6 is fixedly connected to the outer side of the triangular bearing block 5. The limiting buckle 6 is slidably connected to both the mounting base 1 and the insulating body 2. An insertion handle 7 is rotatably connected to the middle position of the lower end of the mounting base 1. The insertion handle 7 is fixedly connected to the threaded shaft 3. An inclined pressing surface 12 is formed on the outer side of the square compression post 4. The inclined pressing surface 12 fits against the inner side of the triangular bearing block 5. A circular groove is formed on the inner wall of the insulating body 2. The size of the circular slot corresponds to the size of the limiting buckle 6. The upper end of the mounting base 1 has a circular slot. The tube on the upper side of the mounting base 1 can be inserted into the interior of the insulating body 2 to achieve horizontal limiting of the insulating body 2. By rotating the insertion handle 7, the threaded shaft 3 can be rotated, thereby allowing the square extrusion column 4 to move upward. The inclined top pressure surface 12 can extrude the triangular bearing block 5, so that the triangular bearing block 5 can drive the limiting buckle 6 to move outward and insert the limiting buckle 6 into the circular slot inside the insulating body 2. This achieves upper and lower limiting of the insulating body 2. The insulating body 2 can be quickly installed without bonding it to the internal metal rod, and it is convenient for later replacement.

[0025] Please refer to Example 2 Figure 1 , Figure 2 and Figure 5The difference between this embodiment and Embodiment 1 is as follows: A mounting sleeve 8 is slidably connected to the outer side of the insertion handle 7; a top support rod 9 is rotatably connected to the outer side of the mounting sleeve 8; a pin 10 is rotatably connected to the outer end of the top support rod 9; a lateral insertion post 11 is slidably connected to the outer side of the pin 10; the lateral insertion post 11 is fixedly connected to the mounting base 1; positioning buckles 13 are slidably connected to the front and rear side walls of the insertion handle 7; positioning buckles 13 are slidably connected to the mounting sleeve 8; a limiting plate 14 is provided at the lower end of the insertion handle 7; a pull ring 15 is rotatably connected to the lower end of the limiting plate 14; a pull rod 16 is fixedly connected to the upper end of the limiting plate 14; the pull rod 16 is slidably connected to the insertion handle 7; a transmission rod 17 is rotatably connected to the upper end of the pull rod 16; the transmission rod 17 is rotatably connected to the positioning buckle 13; a spring 18 is covered on the surface of the thinner rod body on the lower side of the pull rod 16; rectangular slots are provided on the front and rear sides of the inner side wall of the mounting sleeve 8; the size and position of the rectangular slots are larger than the size and position of the positioning buckles 13. Correspondingly, the mounting sleeve 8 can be fitted over the outside of the insertion handle 7, and through the action of the lateral insertion post 11, it can pass through the hole opened in the mounting bracket. By pushing the mounting sleeve 8 upward, the top support rod 9 can drive the pin 10 to continuously insert into the groove inside the lateral insertion post 11, thereby achieving rapid fixation of the mounting base 1 and enabling multi-point fixation to ensure the installation stability of the mounting base 1. Finally, by pulling the pull ring 15, the limiting plate 14 can drive the pull rod 16 downward, so that the transmission rod 17 can drive the positioning buckle 13 to move inward. After the pull ring 15 is released, the spring 18 extends, so that the pull rod 16 can move upward, so that the transmission rod 17 can drive the positioning buckle 13 to move outward, so that the positioning buckle 13 can quickly position the mounting sleeve 8. At the same time, the mounting sleeve 8 can limit the rotation angle of the insertion handle 7 through the positioning buckle 13 to prevent the threaded shaft 3 from deflecting, so that the overall installation is in a stable state.

[0026] The working principle of this utility model is as follows: In use, the tube on the upper side of the mounting base 1 can be inserted into the insulating body 2, achieving horizontal positioning of the insulating body 2. Rotating the insertion handle 7 causes the threaded shaft 3 to rotate, thereby moving the square pressing column 4 upwards. The inclined top pressure surface 12 then presses against the triangular bearing block 5, causing the triangular bearing block 5 to move the limiting buckle 6 outwards, allowing it to insert into the circular slot inside the insulating body 2. This achieves vertical positioning of the insulating body 2. It allows for quick installation of the insulating body 2 without bonding it to the internal metal rod, facilitating future replacement. The mounting sleeve 8 covers the outside of the insertion handle 7, and the lateral insertion column 11 allows the insert to pass through. The mounting bracket has holes, and by pushing the mounting sleeve 8 upward, the top support rod 9 can drive the pin 10 to continuously insert into the groove inside the side insertion post 11, thereby achieving rapid fixation of the mounting base 1 and enabling multi-point fixation to ensure the installation stability of the mounting base 1. Finally, by pulling the pull ring 15, the limiting plate 14 can drive the pull rod 16 downward, so that the transmission rod 17 can drive the positioning buckle 13 to move inward. After the pull ring 15 is released, the spring 18 extends, so that the pull rod 16 can move upward, so that the transmission rod 17 can drive the positioning buckle 13 to move outward, so that the positioning buckle 13 can quickly position the mounting sleeve 8. At the same time, the mounting sleeve 8 can limit the rotation of the insertion handle 7 through the positioning buckle 13 to prevent the threaded shaft 3 from deflecting, so that the overall installation is in a stable state.
