Description

Technical Field

[0001] This utility model relates to the field of glass insulator technology, and in particular to a glass insulator that is easy to assemble and disassemble. Background Technology

[0002] A device used to support and insulate conductors is called an insulator. If the insulator is made of glass, it is called a glass insulator. Glass insulators are mainly used in high-voltage, ultra-high-voltage, and extra-high-voltage AC and DC transmission lines for insulating and suspending conductors. They are also easy to inspect, have good arc and vibration resistance, are not prone to aging, have large capacitance, and provide uniform voltage distribution in series.

[0003] When in use, the steel cap of a glass insulator is typically installed on the connecting hardware on the crossarm of a utility pole or tower, such as a U-shaped hanging ring or a right-angle hanging plate. The steel foot is generally connected to the connecting hardware (such as a U-shaped hanging ring or a right-angle hanging plate) on the conductor. In practice, to ensure that the glass insulator maintains excellent insulation and withstand voltage performance over a long period, regular maintenance is required. Glass insulators that fail to meet performance standards need to be replaced promptly.

[0004] Therefore, it is extremely important to enable easy disassembly and reassembly of the steel cap and steel foot of the glass insulator and the connecting hardware connected to them. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of glass insulator that is easy to assemble and disassemble, so as to at least achieve the purpose of conveniently detaching the glass insulator from the connecting hardware connected thereto.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An easily detachable glass insulator includes a glass insulator, a steel cap, a steel foot, a first connecting assembly disposed on the steel cap, and a second connecting assembly disposed on the steel foot; the first connecting assembly includes a sleeve plate detachably fitted on the steel cap, and two first connecting plates arranged parallel and vertically on the sleeve plate; the second connecting assembly includes a connecting block movably fitted on the steel foot, and two second connecting plates arranged parallel and vertically on the connecting block.

[0008] Preferably, the outer wall of the steel cap is surrounded by two rings of upper and lower limiting blocks, and the sleeve plate is disposed within the two limiting blocks; the sleeve plate includes two symmetrically arranged sub-plates, a semi-circular hole disposed on one side of the two sub-plates that are close to each other, and a first bolt connecting the two sub-plates; the two semi-circular holes can abut against the outer wall of the steel cap.

[0009] Preferably, the top of the connecting block is provided with a first inverted T-shaped groove that matches the steel foot.

[0010] Preferably, a second bolt is provided on the open side of the first inverted T-shaped groove.

[0011] Preferably, the steel cap is provided with a second inverted T-shaped groove that matches the steel foot.

[0012] Preferably, the glass insulator is umbrella-shaped, and multiple rings are coaxially arranged at the bottom end of the glass insulator.

[0013] Preferably, a hydrophobic layer is provided at the top of the glass insulator.

[0014] Preferably, both the first connecting plate and the second connecting plate are made of steel, and both the outer surfaces of the first connecting plate and the second connecting plate are provided with an anti-corrosion layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By installing a first connecting assembly on the steel cap, including a sleeve plate and two first connecting plates, the two first connecting plates can be directly connected to the U-shaped hanging rings on the crossarm of the utility pole or tower using screws during steel cap installation, thus connecting the steel cap to the crossarm. Similarly, by installing a second connecting assembly on the steel foot, including a connecting block and two second connecting plates, the two second connecting plates can be directly connected to the U-shaped hanging rings on the conductor using screws during steel foot installation, thus connecting the steel foot to the wire, thereby achieving the installation and fixation of the glass insulator. When disassembly is required, the first and second connecting assemblies can be simply removed from the two U-shaped hanging rings, making the operation extremely convenient.

[0017] By movably mounting the sleeve plate onto the steel cap, when multiple glass insulators are connected in series, the sleeve plate can be removed from the steel cap, preventing it from obstructing or hindering the glass insulator connected at the top. Ultimately, only the first connecting assembly needs to be installed on the topmost glass insulator. Similarly, by movably mounting the connecting block onto the steel foot, when multiple glass insulators are connected in series, the connecting block can be removed from the steel foot, preventing it from obstructing or hindering the glass insulator connected at the bottom. Ultimately, only the second connecting assembly needs to be installed on the bottommost glass insulator.

[0018] Through the synergistic effect of the above-mentioned devices, it is easy to install the glass insulator on the two U-shaped hanging rings, and it is also easy to remove it from the two U-shaped hanging rings, thus improving the convenience of disassembly and assembly.

Detailed Implementation

[0024] Example 1

[0025] An easy-to-install and disassemble glass insulator, such as Figure 1 As shown, the device includes a glass insulator 1, a steel cap 2 bonded to the top of the glass insulator 1, a steel foot 3 bonded to the bottom of the glass insulator 1, a first connecting assembly disposed on the steel cap 2, and a second connecting assembly disposed on the steel foot 3; the first connecting assembly includes a sleeve plate 4 detachably sleeved on the steel cap 2, and two first connecting plates 5 disposed parallel and vertically on the sleeve plate 4; the second connecting assembly includes a connecting block 6 movably sleeved on the steel foot 3, and two second connecting plates 7 disposed parallel and vertically on the connecting block 6.

[0026] Furthermore, such as Figure 1-3 As shown, the outer wall of the steel cap 2 is surrounded by two rings of upper and lower limiting blocks 8, and the sleeve plate 4 is disposed within the two limiting blocks 8; as Figure 3 As shown, the sleeve 4 includes two symmetrically arranged plates, semi-circular holes on one side of the two plates that are close to each other, and a first bolt 10 connecting the two plates; the two semi-circular holes can abut against the outer wall of the steel cap 2. Further, as... Figure 1 and Figure 4 As shown, the top of the connecting block 6 is provided with a first inverted T-shaped groove 11 that matches the steel foot 3. Further, as... Figure 1 and 4 As shown, a second bolt 12 is provided on the open side of the first inverted T-shaped groove 11.

[0027] Working principle: such as Figure 1 As shown, when installing the steel cap 2, the two first connecting plates 5 are connected to the U-shaped hanging rings (such as those on the crossarm of the utility pole or tower) set on the crossarm. Figure 1The component above the first connecting plate 5; it is worth noting that the first connecting component and the second connecting component in this utility model are both adapted to the U-shaped hanging ring. In actual implementation, it is necessary to limit the connecting hardware on the crossarm and connected to the wire to the U-shaped hanging ring and connect it with screws (existing technology, not shown in the figure) to connect the steel cap 2 to the crossarm.

[0028] When installing the steel foot 3, the two second connecting plates 7 are connected to the U-shaped hanging ring on the conductor (refer to the U-shaped hanging ring above the nut, which is not shown in the figure in the existing technology) by screws to connect the steel foot 3 to the wire, thereby realizing the installation and fixation of the glass insulator.

[0029] When disassembly is required, simply remove the first and second connecting components from the two U-shaped hanging rings; the operation is extremely convenient.

[0030] It is worth noting that the first connecting plate 5 is provided with screw holes that are compatible with the screws and the first bolt 10, which is existing technology and is not shown in the figure; the connecting block 6 is provided with screw holes that are compatible with the second bolt 12, which is existing technology and is not shown in the figure.

[0031] Example 2

[0032] In practice, multiple glass insulators are typically used in series. Based on this, and building upon Example 1, as follows... Figure 1 and Figure 4 As shown, the steel cap 2 is provided with a second inverted T-shaped groove 13 that matches the steel foot 3. In specific series connection, the steel foot 3 is directly inserted into the side of the second inverted T-shaped groove 13, and is completely inserted into the second inverted T-shaped groove 13, thereby achieving the purpose of connecting multiple glass insulators in series.

[0033] When multiple glass insulators are connected in series, the sleeve plate 4 needs to be removed from the steel cap 2 to avoid the sleeve plate 4 blocking or hindering the glass insulator connected at the top. In the end, only the first connecting component needs to be installed on the topmost glass insulator.

[0034] In addition, the connecting block 6 needs to be removed from the steel foot 3 to prevent the connecting block 6 from blocking and hindering the glass insulator connected in series at its bottom end. Finally, only the second connecting component needs to be installed on the bottommost glass insulator.

[0035] Example 3

[0036] Based on Example 1 or 2, such as Figure 1As shown, the glass insulator 1 is umbrella-shaped, and multiple rings 14 are coaxially arranged at the bottom end of the glass insulator 1. By defining the shape of the glass insulator 1, this utility model enables its top surface to form a structure that is high in the center and low around the edges, thus making it less prone to dust accumulation and improving the insulation performance of the glass insulator 1.

[0037] Furthermore, a hydrophobic layer (existing technology, not shown in the figure) is provided at the top of the glass insulator 1. The hydrophobic layer is made of polytetrafluoroethylene, which is not only resistant to acids and alkalis, but also has extremely strong hydrophobicity to prevent rainwater from depositing.

[0038] Furthermore, both the first connecting plate 5 and the second connecting plate 7 are made of steel, and both the outer surfaces of the first connecting plate 5 and the second connecting plate 7 are provided with an anti-corrosion layer. The anti-corrosion layer is made of polytetrafluoroethylene (PTFE), which has extremely strong corrosion resistance, effectively delaying the corrosion of the first connecting plate 5 and the second connecting plate 7, improving their performance, and thus ensuring long-term connection between the glass insulator and external components.
