A suspension porcelain insulator with an umbrella disc

Abstract

This utility model discloses a suspension porcelain insulator with an umbrella disc, relating to the technical field of suspension porcelain insulators. It includes an installation assembly, an insulating component on the inner side of the installation assembly, a suspension component at one end of the installation assembly, and an assembly component at the other end. The installation assembly includes a sleeve, with an adjusting rod slidably connected inside the sleeve. By setting up the installation assembly, and because the protective rods are inclined in a Z-shape, with two protective rods located at the top and bottom of the sleeve respectively, when the suspension porcelain insulator is used in rainy weather, rainwater will flow downwards along the connecting rods. When it reaches the protective rods, the rainwater will drain out along the top of one side of the protective rod or the bottom of the other side, avoiding the formation of a continuous water curtain that flows directly from the suspension assembly to the assembly component, causing flashover. This improves the practicality of the suspension porcelain insulator.

Description

Technical Field

[0001] This utility model relates to the technical field of suspension porcelain insulators, and in particular to a suspension porcelain insulator with an umbrella disc. Background Technology

[0002] Suspension porcelain insulators are key components for insulating and fixing conductors in high-voltage overhead transmission and distribution lines. Their core function is to ensure the safe and stable operation of the power system through the synergistic effect of ceramic insulators and metal accessories. Insulators are designed to increase creepage distance. Suspension porcelain insulators are suspended and assembled with fuse tubes to form fuses. To avoid flashover caused by continuous water curtains in rainy or foggy weather, umbrella discs of different sizes are installed on the porcelain insulators.

[0003] The patent titled "A Suspension Porcelain Insulator" (patent application number: 202021437352.0) discloses a suspension porcelain insulator, relating to the field of insulator technology. It includes a mounting assembly, with an insulating component on its inner side, a wiring component at one end, and a hook component at the other end. The mounting assembly includes a U-shaped frame, with a front mounting seat fixedly connected to one end and a rear mounting seat fixedly connected to the other end. Positioning grooves are formed on the surfaces of both the front and rear mounting seats, and fastening screw holes are formed on their sides. By allowing the insulating posts of the insulator to be independently disassembled and installed, damaged insulating posts can be replaced and maintained individually without replacing the entire insulator, thus reducing maintenance costs. The wiring frame can be pulled along the limiting slide on the mounting rod, allowing the insulator to be fitted with fuse tubes of different lengths.

[0004] In the above case, although the insulating columns of the insulator can be disassembled and installed independently, making it convenient to replace and maintain damaged insulating columns separately without replacing the entire damaged insulator, which helps to reduce the maintenance cost of the insulator, its U-shaped frame design makes it easy for rainwater to form a continuous water curtain along the U-shaped frame from the hook assembly to the wiring assembly in rainy or foggy weather, causing flashover, thus reducing the practicality of the suspension porcelain insulator.

[0005] Therefore, it is necessary to propose a suspension porcelain insulator with a shawl disc to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a suspension porcelain insulator with an umbrella disc to solve the problem mentioned in the background art, where rainwater forms a continuous water curtain along the U-shaped frame from the hook assembly to the wiring assembly in rainy or foggy weather, causing flashover and thus reducing the practicality of the suspension porcelain insulator.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a suspension porcelain insulator with an umbrella disc, comprising an installation assembly, an insulation assembly provided on the inner side of the installation assembly, a suspension assembly provided at one end of the installation assembly, and an assembly assembly provided at the other end of the installation assembly;

[0008] The mounting assembly includes a sleeve, an adjusting rod slidably connected inside the sleeve, a protective rod fixedly connected to the top end of the adjusting rod, a connecting rod fixedly connected to the top end of the protective rod, a mounting base fixedly connected to one end of the connecting rod, a slot provided at the bottom of the inner cavity of the mounting base, and an insertion hole provided at the top of the inner cavity of the mounting base.

[0009] Preferably, the protective rod is in the shape of an inclined Z, and there are two protective rods, which are located at the top and bottom of the sleeve, respectively.

[0010] Preferably, the adjusting rod has multiple adjusting holes inside, and adjusting bolts are inserted into the adjusting holes. The outside of the adjusting bolts is connected to the inside thread of the sleeve.

[0011] Preferably, the insulating component includes an insulating column, the outside of which is provided with multiple umbrella discs, and the top and bottom of the insulating column are fixedly connected with assembly blocks, the assembly blocks having screw holes inside.

[0012] The outside of the assembly block engages with the inside of the slot.

[0013] Preferably, the suspension assembly includes a mounting block, the bottom of which is fixedly connected to a first threaded post, and the top of which is fixedly connected to a hook;

[0014] The outside of the first threaded post is inserted into the inside of the insertion hole, and the outside of the first threaded post is threadedly connected to the inside of the threaded hole.

[0015] Preferably, the assembly includes a sleeve rod, the top of which is fixedly connected to a second threaded post, and the bottom of which is fixedly connected to a terminal block;

[0016] The outside of the second threaded post is inserted into the inside of the insertion hole, and the outside of the second threaded post is threadedly connected to the inside of the threaded hole.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By setting up the installation components, since the protective rod is inclined in a Z-shape and the two protective rods are located at the top and bottom of the sleeve respectively, when the suspension porcelain insulator is used in rainy weather, rainwater will flow down along the connecting rod. When it reaches the protective rod, the rainwater will be discharged along the top of one side of the protective rod or the bottom of the other side, avoiding the formation of a continuous water curtain that flows directly from the suspension component to the assembly component and causes flashover. This improves the practicality of the suspension porcelain insulator.

[0019] 2. When the installation component needs to install and use insulation components of different batches and lengths, the adjusting bolt can be rotated in the opposite direction to separate the adjusting bolt from the sleeve. Then, the adjusting rod can be pulled upward to select a suitable adjusting hole. Finally, the adjusting bolt can be used to fix the adjusting rod. This allows for quick adjustment of the distance between the two mounting seats, facilitating the installation and use of insulation components of different lengths and bringing convenience to the use of the device.

[0026] 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.

[0027] This utility model provides, for example Figures 1-5 The suspended porcelain insulator with a parapet disc shown includes an installation assembly 1, an insulation assembly 2 disposed inside the installation assembly 1, a suspension assembly 3 disposed at one end of the installation assembly 1, and an assembly assembly 4 disposed at the other end of the installation assembly 1. The installation assembly 1 includes a sleeve 101, an adjusting rod 102 slidably connected inside the sleeve 101, a protective rod 103 fixedly connected to the top end of the adjusting rod 102, a connecting rod 104 fixedly connected to the top end of the protective rod 103, a mounting base 105 fixedly connected to one end of the connecting rod 104, a slot 106 opened at the bottom of the inner cavity of the mounting base 105, and an insertion hole 107 opened at the top of the inner cavity of the mounting base 105. The protective rod 103 is in an inclined Z-shape, and there are two protective rods 103, which are located at the top and bottom of the sleeve 101, respectively. Because the protective rod 103 is slanted in a Z-shape, and the two protective rods 103 are located at the top and bottom of the sleeve 101 respectively, when the suspension porcelain insulator is used in rainy weather, rainwater will flow down along the connecting rod 104. When it reaches the protective rod 103, the rainwater will be discharged along the top of one side of the protective rod 103 or the bottom of the other side, avoiding the formation of a continuous water curtain that directly reaches the assembly assembly 4 from the suspension assembly 3, causing flashover. This improves the practicality of the suspension porcelain insulator.

[0028] In addition, the adjusting rod 102 has multiple adjusting holes 108 inside, and adjusting bolts 109 are inserted into the adjusting holes 108. The outside of the adjusting bolts 109 is threadedly connected to the inside of the sleeve 101. The insulating component 2 includes an insulating column 201. Multiple umbrella discs are provided on the outside of the insulating column 201. Assembly blocks 202 are fixedly connected to the top and bottom of the insulating column 201. The assembly block 202 has screw holes 203 inside, and the outside of the assembly block 202 is engaged with the inside of the slot 106. When the mounting assembly 1 needs to install and use insulation components 2 of different batches and lengths, the adjusting bolt 109 can be rotated in the opposite direction to separate the adjusting bolt 109 from the sleeve 101. Then, the adjusting rod 102 can be pulled upward to select a suitable adjusting hole 108, and the adjusting bolt 109 can be used to fix the adjusting rod 102. This allows for quick adjustment of the distance between the two mounting seats 105, facilitating the installation and use of insulation components 2 of different lengths. The assembly block 202 at the top of the insulating column 201 is inserted into the slot 106 above the mounting assembly 1, and the assembly block 202 at the bottom of the insulating column 201 is inserted into the slot 106 below the mounting assembly 1, which brings convenience to the use of the device.

[0029] Next, the suspension assembly 3 includes a mounting block 301. A first threaded post 302 is fixedly connected to the bottom of the mounting block 301, and a hook 303 is fixedly connected to the top of the mounting block 301. The exterior of the first threaded post 302 is inserted into the interior of the insertion hole 107, and the exterior of the first threaded post 302 is threadedly connected to the interior of the screw hole 203. When assembling the suspension assembly 3, firstly, the first threaded post 302 is inserted into the insertion hole 107 of the mounting base 105 above the mounting assembly 1. Then, the mounting block 301 is rotated so that the first threaded post 302 is threadedly connected to the screw hole 203, thus securing it.

[0030] Finally, assembly component 4 includes a sleeve 401, with a second threaded post 402 fixedly connected to the top of the sleeve 401 and a terminal block 403 fixedly connected to the bottom of the sleeve 401. The exterior of the second threaded post 402 is inserted into the interior of the socket 107, and the exterior of the second threaded post 402 is threadedly connected to the interior of the screw hole 203. When assembly component 4 needs to be assembled, first insert the second threaded post 402 into the socket 107 of the mounting base 105 below the mounting component 1, and then rotate the sleeve 401 so that the second threaded post 402 is threadedly connected to the screw hole 203, thus fixing it in place.

[0031] Working principle: Because the protective rod 103 is in an inclined Z-shape, and the two protective rods 103 are located at the top and bottom of the sleeve 101 respectively, when the suspension porcelain insulator is used in rainy weather, rainwater will flow down along the connecting rod 104. When it reaches the protective rod 103, the rainwater will drain out along the top of one side of the protective rod 103 or the bottom of the other side, avoiding the formation of a continuous water curtain that flows directly from the suspension assembly 3 to the assembly assembly 4, causing flashover. This improves the practicality of the suspension porcelain insulator. When the installation assembly 1 needs to install and use insulation assemblies 2 of different batches and lengths, it can... By rotating the adjusting bolt 109 in the opposite direction to separate the adjusting bolt 109 from the sleeve 101, and then pulling the adjusting rod 102 upward to select a suitable adjusting hole 108, and then fixing the adjusting rod 102 with the adjusting bolt 109, the distance between the two mounting seats 105 can be quickly adjusted, which is convenient for installing and using insulating components 2 of different lengths. The assembly block 202 at the top of the insulating column 201 is inserted into the slot 106 above the mounting component 1, and the assembly block 202 at the bottom of the insulating column 201 is inserted into the slot 106 below the mounting component 1, which brings convenience to the use of the device.
