Description

Technical Field

[0001] This utility model 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 component at ground potential, capable of withstanding voltage and mechanical stress.

[0003] An insulator typically consists of an insulator body and two connecting flanges positioned at the top and bottom. The connecting flanges between each group are secured by a mandrel. During assembly, the mandrel needs to be manually engaged and secured multiple times by hanging the flanges and striking them. This process is quite lengthy and consumes a lot of manpower, making the assembly of insulators cumbersome and inefficient. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that during assembly, the insulator core rod needs to be fixed by manual means multiple times by attaching and hammering the flange, which is a lengthy process that consumes a lot of manpower, making the assembly of the insulator cumbersome and inefficient.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an assembled porcelain insulator, comprising multiple sets of mutually cooperating ceramic insulators and connecting rods, wherein the connecting rods are disposed at the lower end of the ceramic insulators, and a chuck is fixedly connected to the bottom end of the connecting rods; an installation cavity is provided inside the top end of the ceramic insulators, and a retaining cavity is provided in the middle of the installation cavity; three evenly distributed sliding grooves are provided on the outer periphery of the installation cavity, and sliding retaining plates are slidably connected in each sliding groove; a sliding pin is fixedly connected to the rear end of each sliding retaining plate; a rotating disk is rotatably connected to the top end of the installation cavity, and the rotating disk is positioned corresponding to the sliding pins. The device features an arc-shaped guide groove, with the sliding pin slidably connected inside the corresponding arc-shaped guide groove. By rotating the rotating disk, multiple sliding pins can be moved synchronously in conjunction with the arc-shaped guide groove, causing multiple sliding plates to move closer or further apart. During installation and connection, the rotating disk can be rotated after the chuck is inserted into the chuck cavity, causing multiple sliding plates to form a barrier and preventing the chuck from detaching from the chuck cavity. During disassembly, the rotating disk can be rotated in the opposite direction to move the sliding plates further apart, thus removing any obstructions on the chuck and facilitating disassembly. This device is simple and quick to operate during connection, installation, and disassembly, reducing installation time and labor costs.

[0006] In a preferred embodiment, a pressing block is fixedly connected to the top of the rotating disk. The pressing block makes it easier for the operator to drive the rotation of the rotating disk, and it can be driven directly by actions such as the top hammer.

[0007] In a preferred embodiment, the outer surface of the ceramic insulator is covered with a magnesium fluoride nanocrystalline coating, which can reduce the surface energy of the ceramic insulator, improve the hydrophobicity of the outer surface of the ceramic insulator, and enhance its anti-fouling ability.

[0008] In a preferred embodiment, the magnesium fluoride nanocrystalline coating contains uniformly dispersed titanium dioxide particles with a particle size of <100nm. These titanium dioxide particles can be excited by ultraviolet light to decompose contaminants remaining on the ceramic insulator, thereby reducing the probability of flashover and maintenance costs.

[0009] In a preferred embodiment, the connecting rod is inserted into the lower end of the ceramic insulator and sintered with the ceramic insulator. The connecting rod and the ceramic insulator are co-fired at high temperature, which can form stable chemical bonds and improve the strength between the ceramic insulator and the connecting rod.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model can drive multiple sliding pins to move synchronously by rotating a rotating disk and cooperating with an arc-shaped guide groove, so that multiple sliding plates move closer or further apart. During installation and connection, the rotating disk can be rotated after the chuck is inserted into the chuck cavity, so that multiple sliding plates form a block and prevent the chuck from falling out of the chuck cavity. During disassembly, the rotating disk can be rotated in the opposite direction to move the sliding plates away from each other, so that there is no obstruction on the chuck and it is easy to disassemble. This device is simple and quick to operate during connection, installation and disassembly, reducing installation time and labor costs.

[0012] 2. This utility model is provided with a magnesium fluoride nanocrystalline coating, and titanium dioxide particles with a particle size of <100nm are uniformly dispersed in the magnesium fluoride nanocrystalline coating, which can improve the hydrophobicity of the outer surface of the ceramic insulator. Furthermore, the titanium dioxide particles are excited by ultraviolet light to decompose the pollutants remaining on the ceramic insulator, thereby reducing the probability of flashover and reducing maintenance costs.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an assembled porcelain insulator, comprising multiple sets of mutually cooperating ceramic insulators 1 and connecting rods 2. The connecting rods 2 are disposed at the lower end of the ceramic insulators 1, and a chuck 3 is fixedly connected to the bottom end of the connecting rods 2. An installation cavity 8 is provided inside the top of the ceramic insulator 1, and a locking cavity 10 is provided in the middle of the installation cavity 8. Three evenly distributed sliding grooves 9 are provided on the outer periphery of the installation cavity 8, and sliding locking plates 7 are slidably connected in each of the sliding grooves 9. Sliding pins 11 are fixedly connected to the rear ends of each sliding locking plate 7. A rotating disk 4 is rotatably connected to the top of the installation cavity 8, and an arc-shaped guide groove 6 is provided on the rotating disk 4 corresponding to the sliding pin 11. The sliding pins 11 are slidably connected inside the arc-shaped guide groove 6 at the corresponding location. By rotating the rotating disk 4, the multiple sliding pins 11 can be moved synchronously with the arc-shaped guide groove 6, so that the multiple sliding plates 7 move closer or further apart. During installation and connection, the rotating disk 4 can be rotated after the chuck 3 is inserted into the chuck cavity 10, so that the multiple sliding plates 7 form a block, which can prevent the chuck 3 from falling out of the chuck cavity 10. During disassembly, the rotating disk 4 can be rotated in the opposite direction to make the sliding plates 7 move further apart, so that there is no obstruction on the chuck 3, which is convenient for disassembly. This device is simple and quick to operate during connection, installation and disassembly, reducing installation time and labor costs.

[0021] like Figure 1-4 As shown, a pressing block 5 is fixedly connected to the top of the rotating disk 4. The pressing block 5 makes it easier for the operator to drive the rotation of the rotating disk 4, and it can be driven directly by actions such as the top hammer.

[0022] like Figure 1-4 As shown, the outer surface of the ceramic insulator 1 is covered with a magnesium fluoride nanocrystalline coating, which can reduce the surface energy of the ceramic insulator 1, making the surface molecules of the ceramic insulator 1 repel other substances, making it difficult for water and pollutants to adhere, thereby improving the anti-fouling ability of the ceramic insulator 1.

[0023] like Figure 1-4 As shown, titanium dioxide particles with a particle size of <100nm are uniformly dispersed in the magnesium fluoride nanocrystalline coating. The titanium dioxide particles can generate active oxygen under ultraviolet light, thereby decomposing pollutants remaining on the ceramic insulator 1, reducing the probability of flashover and reducing maintenance costs.

[0024] like Figure 1-4 As shown, the connecting rod 2 is inserted into the lower end of the ceramic insulator 1 and sintered with the ceramic insulator 1. The connecting rod 2 and the ceramic insulator 1 are co-fired at high temperature, which can form stable chemical bonds and improve the strength between the ceramic insulator 1 and the connecting rod 2.

[0025] Working principle: During installation and connection, after the chuck 3 is inserted into the cavity 10, the pressing block 5 is pushed to rotate the rotating disk 4. In conjunction with the arc-shaped guide groove 6, multiple sliding pins 11 are driven to move, so that multiple sliding plates 7 form a block to prevent the chuck 3 from disengaging from the cavity 10, thereby achieving mutual connection. During disassembly, the pressing block 5 is pushed in the opposite direction to rotate the rotating disk 4 in the opposite direction, so that the sliding plates 7 are separated from each other, so that there is no obstruction on the chuck 3, and the chuck 3 can be directly removed for disassembly. This device is simple and quick to operate during connection, installation and disassembly, reducing installation time and labor costs.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
