Description

Technical Field

[0001] This utility model relates to the field of insulators, specifically to a combined rod-shaped insulator. Background Technology

[0002] Rod insulators are widely used in high-voltage transmission lines due to their light weight, compact size, high mechanical strength, and excellent resistance to breakage.

[0003] Currently, most rod insulators are manufactured to fixed sizes, but different electrical components require insulators of different heights, which causes great inconvenience to production. In addition, if one skirt of a rod insulator is damaged during use, the entire rod insulator needs to be replaced to ensure the safe operation of the line, resulting in a great waste of resources and an increase in costs. Utility Model Content

[0004] The purpose of this utility model is to provide a combined rod insulator, which solves the problem that existing rod insulators are usually of fixed size, while different electrical components require insulators of different heights, which brings great inconvenience to production. At the same time, once one of the sheds of the rod insulator is damaged, the entire rod insulator needs to be replaced to ensure the safe operation of the line, resulting in great waste of resources and increased costs.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A composite rod insulator includes several assembly parts, each assembly part including an insulating assembly post. One end of the insulating assembly post is provided with a connecting screw, and the other end is provided with a mounting screw hole for the connecting screw to be screwed in. The outer wall of the insulating assembly post is threaded with an anti-rotation bolt for fixing the connecting screw screw screwed into the mounting screw hole. The outer wall of the insulating assembly post is provided with several sets of sheds. Adjacent sets of assembly parts are axially connected through the connecting screw and the mounting screw hole. The top and bottom ends of the assembly parts opposite to each other are respectively connected with a connecting cap one and a connecting cap two.

[0007] A further improvement is that an insulating sleeve is movably sleeved on the outer side of the docking screw, and the insulating sleeve is inserted into a groove opened at one end of the insulating assembly column.

[0008] A further improvement is that the outer diameter of the mating screw is smaller than the inner diameter of the insulating assembly post.

[0009] A further improvement is that an insulating magnetic body one is embedded at one end of the insulating assembly column and outside the mounting screw hole, and an insulating magnetic body two is provided at one end of the insulating sleeve outside the groove to attract the insulating magnetic body one.

[0010] A further improvement is that the umbrella skirt is interference-fitted onto the outer wall of the insulating assembly column, and the umbrella skirt is integrally provided with several sets of protrusions, and the protrusions are provided with fasteners that are fixed to the outer wall of the insulating assembly column.

[0011] A further improvement is that the first connecting cap is connected to the mounting screw hole in the top assembly via a screw member, and the second connecting cap has a threaded hole for connecting to the mating screw in the bottom assembly.

[0012] The beneficial effects of this utility model are as follows: The rod-shaped insulator of this invention is composed of several assembly parts connected together. Adjacent assembly parts are connected by butt screws and mounting screw holes. The usage height of the rod-shaped insulator can be adjusted as needed, improving the flexibility of the rod-shaped insulator and meeting the installation needs of different heights. In addition, if the shed in one of the assembly parts is damaged, it is not necessary to replace the entire rod-shaped insulator. The damaged assembly part can be removed and replaced separately, which greatly reduces the use cost and resource waste. Attached Figure Description

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example 1

[0019] Please see the appendix Figure 1-3A composite rod-shaped insulator includes several assembly parts, each including an insulating assembly post 1. One end of the insulating assembly post 1 has a connecting screw 4, and the other end has a mounting screw hole 10 for the connecting screw 4 to be screwed into. An anti-rotation bolt 7 is threaded into the outer wall of the insulating assembly post 1 to fix the connecting screw 4 screwed into the mounting screw hole 10. A T-shaped through hole is radially formed on the outer wall of the insulating assembly post 1. This T-shaped through hole serves both as an insertion channel for the anti-rotation bolt 7 and as a means to accommodate its end. Tightening the anti-rotation bolt 7 secures the connecting screw 4 screwed into the mounting screw hole 10, preventing loosening and ensuring the connection stability of adjacent assembly parts. The outer wall of the insulating assembly post 1 has several sets of awnings 2. Adjacent assembly parts are connected by connecting... The screw 4 and the mounting screw hole 10 are axially connected. In this way, the working height of the rod insulator can be adjusted as needed. There are two ways to adjust the working height: one is by adding or removing the assembly part, and the other is by adjusting the depth of the connecting screw 4 into the mounting screw hole 10. This improves the flexibility of the rod insulator and meets the installation needs of different heights. Furthermore, if the shed 2 in one of the assemblies is damaged, it is not necessary to replace the entire rod insulator. Only the damaged assembly part needs to be removed and replaced, which greatly reduces the cost of use. The top and bottom assemblies are respectively connected to the opposite ends of the connecting cap 5 and connecting cap 6, which are used to install the rod insulator in the required position. These details will not be described further here.

[0020] Preferably, in this embodiment, the outer diameter of the connecting screw 4 is smaller than the inner diameter of the insulating assembly column 1; an insulating sleeve 9 is movably sleeved on the outer side of the connecting screw 4, the inner diameter of the insulating sleeve 9 is larger than the outer diameter of the connecting screw 4, the vertical cross section of the insulating sleeve 9 is T-shaped, the insulating sleeve 9 is inserted into the groove opened at one end of the insulating assembly column 1, and the height of the insulating sleeve 9 is greater than the depth of the mounting screw hole 10.

[0021] After several assembly parts are connected by the mating screws 4 and the mounting screw holes 10, the insulating sleeve 9 is pulled to move so that it covers the connection between two adjacent assembly parts. The insulating sleeve 9 protects the mating screws 4 exposed at the connection, reduces the damage to the mating screws 4 exposed to the outside, extends the service life of the mating screws 4, and improves the connection stability between adjacent assembly parts.

[0022] Preferably, in this embodiment, an insulating magnetic body 8 is embedded at one end of the insulating assembly column 1 and outside the mounting screw hole 10. An insulating magnetic body 11 is provided at one end of the insulating sleeve 9 outside the groove to attract the insulating magnetic body 8. The insulating magnetic bodies 8 and 11 have opposite magnetic properties. For example, the insulating magnetic bodies 8 and 11 can be widely used in the art as insulating magnets. The insulating sleeve 9 can be positioned by the cooperation of the insulating magnetic bodies 8 and 11, so that the insulating sleeve 9 is not easy to move after it is sleeved on the outside of the docking screw 4.

[0023] Preferably, in this embodiment, the first connecting cap 5 is connected to the mounting screw hole 10 in the top assembly via a screw member, and the second connecting cap 6 is provided with a threaded hole for connecting to the mating screw 4 in the bottom assembly, so as to realize the quick assembly and disassembly of the first connecting cap 5 and the second connecting cap 6.

[0024] Example 2

[0025] Please see the appendix Figure 1 Based on embodiment 1, in this embodiment, the umbrella skirt 2 is interference-fitted onto the outer wall of the insulating assembly column 1. The bottom of the umbrella skirt 2 is integrally provided with several sets of protrusions, and the protrusions are provided with fasteners 3 that are fixed to the outer wall of the insulating assembly column 1. The fasteners 3 are, for example, bolts, and the outer wall of the insulating assembly column 1 is provided with screw holes for the bolts to enter.

[0026] With the above-described configuration, the several sets of umbrella skirts 2 on the outer wall of the insulating assembly column 1 are independent of each other. When one set of umbrella skirts 2 is damaged, after removing the assembly part it belongs to, the fastener 3 on the damaged umbrella skirt 2 can be unscrewed, and the umbrella skirt 2 can be removed from one end of the insulating assembly column 1. Then, a new umbrella skirt 2 can be replaced and fixed to the insulating assembly column 1 by the new umbrella skirt 2 and the fastener 3. There is no need to replace the entire assembly part, which further reduces the cost of use.

[0027] It should be noted that the above-mentioned insulating assembly column 1, umbrella skirt 2, fastener 3, connecting screw 4, anti-rotation bolt 7, insulating sleeve 9, etc. are all made of insulating materials, such as ceramics and plastics, and will not be described in detail here.

[0028] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
