Description

Technical Field

[0001] This utility model relates to the field of spliced ​​suspension porcelain insulators, specifically a spliced ​​suspension porcelain insulator. Background Technology

[0002] In the construction and operation and maintenance of high-voltage transmission lines, suspension porcelain insulators are the core components for achieving insulation between conductors and towers and transmitting line loads. Their installation adaptability and splicing reliability directly affect the stability and operation and maintenance efficiency of the transmission system.

[0003] Existing traditional suspension porcelain insulators mostly have fixed-size mounting components, which can only be adapted to tower support structures of specific thicknesses. When faced with tower support components of different specifications and thicknesses, it is necessary to replace the corresponding model of mounting accessories, which reduces construction efficiency. In traditional splicing structures, the positioning between insulator units mostly relies on the gap fit between components, without a dedicated coaxial positioning mechanism. After splicing, the overall stress is easily uneven due to coaxiality deviation. When subjected to loads such as conductor tension and wind vibration for a long time, stress concentration is likely to occur at the connection points, shortening the service life of the insulator. Utility Model Content

[0004] The purpose of this invention is to provide a spliced ​​suspension porcelain insulator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spliced ​​suspension porcelain insulator, comprising an insulator body and a sub-insulator, wherein the insulator body comprises a cylinder, a large umbrella skirt is fixedly connected to the cylinder, a small umbrella skirt is fixedly connected to the cylinder, and a fixing component is fixedly connected to the top of the cylinder.

[0006] Preferably, the fixing component includes two limiting grooves, which are symmetrically arranged. A slider is slidably connected in the limiting groove. A movable plate is fixedly connected to the top of the slider. The movable plates are screwed together by bolts and nuts. A splicing structure is fixedly connected to the bottom of the cylinder.

[0007] Preferably, the splicing structure includes a round rod, on which a circular ring block is slidably connected, and a plug is fixedly connected to the top of the round rod.

[0008] Preferably, the auxiliary insulator includes a column, an upper shed skirt fixedly connected to the column, a lower shed skirt fixedly connected to the column, and a locking structure fixedly connected to the top of the column.

[0009] Preferably, the locking structure includes a disc with a cavity in the center, the cavity fitting into the plug, a locking groove inside the disc, a locking bolt slidably connected inside the locking groove, a spring on the locking bolt, and a locking block fixedly connected to one end of the locking bolt.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the sliding engagement of the symmetrical limiting groove and the slider, along with the bolt and nut connection of the moving plate, allows for flexible adjustment of the bolt tightness to adapt to different thicknesses of the tower support structure, ensuring that the insulator body is firmly installed without loosening, thus improving the versatility and stability of the installation. The locking structure achieves coaxial positioning through the engagement of the disc cavity and the plug. The locking bolt and the locking block, driven by a spring in the locking slot, are tightly engaged with the plug groove by the spring force, ensuring a stable connection between the main body and the sub-body and strong resistance to detachment. It can also be easily unlocked by the sliding ring toggle block, enabling quick disassembly. Attached Figure Description

[0018] 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.

[0019] All electronic components in this application are controlled by an external controller.

[0020] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a spliced ​​suspension porcelain insulator, including an insulator body and a sub-insulator. The insulator body includes a cylinder 1 for fixing and supporting a large umbrella skirt 2 and a small umbrella skirt 3. The large and small umbrella skirts 3 are alternately distributed, which can increase the creepage distance on the surface of the insulator. The large umbrella skirt 2 is fixedly connected to the cylinder 1, and the small umbrella skirt 3 is fixedly connected to the cylinder 1. The small umbrella skirt 3 is located below the large umbrella skirt 2. A fixing component is fixedly connected to the top of the cylinder 1.

[0021] Specifically, the fixing component includes two limiting grooves 4, which are symmetrically arranged. A slider 5 is slidably connected in the limiting groove 4. A movable plate 6 is fixedly connected to the top of the slider 5. The movable plates 6 are screwed together by bolts 7 and nuts 8. A splicing structure is fixedly connected to the bottom of the cylinder 1. By screwing the two movable plates 6 together, the clamping force is converted into a fixed friction force to ensure that the main body does not loosen on the tower. At the same time, the tightness of the bolts 7 can be adjusted to adapt to support structures of different thicknesses.

[0022] The splicing structure includes a round rod 9, on which a circular ring block 10 is slidably connected. A plug 11 is fixedly connected to the top of the round rod 9. The circular ring block 10 is located below the plug 11, and there is a certain groove between the circular ring block 10 and the plug 11. When it is necessary to separate the main body and the sub-body, sliding the circular ring block 10 can push the locking bolt 18 in the locking structure of the sub-body. The circular ring block 10 causes the locking block 20 to disengage from the locking groove of the plug 11, thereby releasing the locking state of the main body and the sub-body and realizing convenient disassembly.

[0023] Based on the above embodiments, specifically, the sub-insulator includes a column 12, an upper shed 13 fixedly connected to the column 12, and a lower shed 14 fixedly connected to the column 12, forming a continuous shed sequence with the large and small sheds 3 of the main body, thereby extending the total creepage distance of the entire spliced ​​insulator; a locking structure is fixedly connected to the top of the column 12.

[0024] Specifically, the locking structure includes a disc 15, a cavity 16 in the center of the disc 15, the cavity 16 being fitted with the plug 11, a locking slot 17 inside the disc 15, a locking bolt 18 slidably connected inside the locking slot 17, a spring 19 on the locking bolt 18, and a locking block 20 fixedly connected to one end of the locking bolt 18.

[0025] When the plug 11 of the insulator body is aligned with the locking structure of the sub-insulator, the plug 11 is first inserted into the cavity 16 in the center of the disc 15. The precise engagement of the cavity 16 and the plug 11 achieves positioning and ensures coaxial alignment. At this time, the locking bolt 18 in the locking slot 17 slides radially under the force of the spring 19, driving the locking block 20 to move towards the plug 11. Finally, the locking block 20 is embedded in the preset groove of the plug 11. The continuous pushing force of the spring 19 can make the locking block 20 engage with the groove, preventing the plug 11 from coming out of the cavity 16 and achieving a stable connection between the body and the sub-body. When it is necessary to disassemble, the circular lever 10 on the splicing structure of the insulator body is slid. The circular lever 10 pushes the locking bolt 18 to overcome the elastic force of the spring 19 and slides in the opposite direction along the locking slot 17, forcing the locking block 20 to disengage from the groove of the plug 11 and release the locking state.

[0026] Working principle: The insulator body increases the creepage distance by alternating large and small sheds 3 on the cylinder 1. The top fixing component uses the slider 5 in the limiting groove 4 to drive the moving plate 6. The clamping force generated by the bolt 7 and nut 8 fixes the body to the tower and is compatible with support structures of different thicknesses. When splicing is required, the plug 11 on the insulator body is inserted into the cavity 16 of the locking structure at the top of the auxiliary insulator column 12 to achieve coaxial positioning. The locking bolt 18 in the locking slot 17 drives the locking block 20 to be embedded into the groove of the plug 11 under the action of the spring 19, forming a stable connection. The upper and lower sheds 14 of the auxiliary insulator and the sheds of the main body form a continuous sequence, which can extend the total creepage distance. When disassembling, the circular ring block 10 on the sliding rod 9 pushes the locking bolt 18 to overcome the elastic force of the spring 19, so that the locking block 20 is disengaged from the groove of the plug 11 and the locking state is released.
