Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulators, and in particular to an adhesive-bonded structure and a high-strength column insulator. Background Technology
[0002] Post-type insulators are crucial support and insulation devices in power systems, widely used in high-voltage transmission lines and substations. Traditional post-type insulators typically consist of a post, an insulator body, and sheds, with the post and insulator body fixed together using an adhesive bonding structure. However, the adhesive bonding structure in existing technology has the following problems:
[0003] First: Traditional glued structures have low connection strength between the column and the insulator body, which is prone to interlayer separation. Especially during long-term use, the connection strength will further decrease due to environmental factors and mechanical stress, affecting the stability and reliability of the insulator.
[0004] Second, traditional glued structures lack real-time monitoring capabilities, making it impossible to detect changes in the health status of the glued structure, such as stress, temperature, and humidity. This may lead to potential problems going undetected and unaddressed, increasing the risk of equipment failure.
[0005] Therefore, it is necessary to propose an adhesive-bonded structure and a high-strength columnar insulator to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an adhesive-bonded structure and a high-strength column insulator to solve the problems of low connection strength and easy interlayer separation in traditional adhesive-bonded structures.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a glue-bound structure, comprising:
[0008] The adhesive structure formed after the adhesive material is molded has a receiving part and a pressing part at its upper and lower ends, respectively. The receiving part is used to limit the leakage of the adhesive material, and the pressing part is used to press the adhesive material onto the receiving part. After the adhesive material is pressed, it is molded into an adhesive structure, which is a cylindrical structure.
[0009] The interlayer connection portion includes an external interlocking structure and an internal interlocking structure. The external interlocking structure includes a structure adapted to the external thread and is used to fix the adhesive structure to the cylindrical internal connector. The internal interlocking structure includes a structure adapted to the annular groove and is used to fix the adhesive structure to the cylindrical external connector.
[0010] This utility model also discloses a high-strength post-type insulator, including an adhesive-bonded structure, and further comprising:
[0011] The insulator consists of a column, an insulator body, and a shed. The column is a cylindrical structure. The insulator body is movably fitted onto the outside of the column. The shed is integrally set on the outer ring of the insulator body. An adhesive channel for filling adhesive material is formed between the inner ring of the insulator body and the outer ring of the column. The adhesive material is formed into an adhesive structure within the adhesive channel.
[0012] Preferably, the outer ring of the column is provided with external threads.
[0013] Preferably, the inner wall of the insulator body is provided with annular grooves, and there are multiple annular grooves, which are distributed at equal intervals along the height direction of the insulator body.
[0014] Preferably, the column is connected by two threaded rings made of adhesive material, which are respectively located in the vertical direction of the adhesive channel.
[0015] Preferably, a rubber sealing ring is fixedly provided at the outer ring of the threaded ring made of the adhesive material.
[0016] Preferably, a support plate is fixedly installed in the middle of the column, and a monitoring element is installed on the support plate. The monitoring element integrates a temperature sensor, a humidity sensor, and a pressure sensor. The column is provided with a reserved hole for connecting the monitoring element to an external wire.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. The adhesive material in the adhesive channel is compressed, and the structural strength is higher than that of traditional adhesive structures. After the adhesive structure is formed, it can be tightly fixed and engaged in the ring groove, which increases the interlayer connection strength between the insulator body and the adhesive structure. At the same time, since the outer ring of the column has external threads, the interlayer connection strength between the adhesive structure and the column is also improved after the adhesive structure is formed.
[0019] 2. The monitoring components can monitor parameters such as stress, temperature, and humidity of the glued structure, monitor the health status of the glued structure in real time, and provide early warning of potential problems;
[0020] 3. The rubber sealing ring has both a limiting function and a sealing function. It can be used to indicate the screw-in depth of the threaded ring made of adhesive material, and it seals both sides of the adhesive channel to prevent the adhesive material from leaking. It has a simple structure and is quite practical. Attached Figure Description

[0026] This utility model provides, for example Figures 1-4 The diagram shows a glued structure and a high-strength column insulator. The glued structure inside the high-strength column insulator has higher strength than that of traditional glued structures, and the connection strength between the column 1 and the insulator body 2 is higher, making it less prone to interlayer separation.
[0027] refer to Figure 1 and Figure 2 As shown, the high-strength column insulator includes a column 1, an insulator body 2, and sheds 3. The column 1 is a cylindrical rod structure. The insulator body 2 is sleeved on the outside of the column 1. There is a glue channel between the outer ring of the column 1 and the inner ring of the insulator body 2. Multiple sheds 3 are provided and are integrally set on the outer ring of the insulator body 2. When glue material is filled into the glue channel, a glue structure 5 is formed, which realizes the fixation between the column 1 and the insulator body 2. The outer ring of the column 1 is provided with external threads, and a threaded ring 4 made of glue material is connected to the external threads through threaded engagement.
[0028] When filling the adhesive channel with adhesive material, first install the threaded ring 4 made of adhesive material at the bottom of the column 1 and seal it at the lower end of the adhesive channel. Then fill the adhesive channel with adhesive material from the top. After the adhesive material is filled, install the threaded ring 4 made of adhesive material at the upper end of the column 1. As the threaded ring 4 made of adhesive material is tightened, the adhesive material in the adhesive channel is compressed, resulting in a structure with high strength compared to traditional adhesive structures.
[0029] refer to Figure 3 and Figure 4As shown, annular grooves 10 are also provided on the inner wall of the insulator body 2. Multiple annular grooves 10 are provided and are evenly distributed along the height direction of the insulator body 2. When the glued structure 5 is formed, it can be tightly fixed and engaged in the annular grooves 10, which increases the interlayer connection strength between the insulator body 2 and the glued structure 5. At the same time, since the outer ring of the column 1 has external threads, the interlayer connection strength between the glued structure 5 and the column 1 is also improved after the glued structure 5 is formed. Therefore, the glued structure 5 with this structure is less likely to detach from the column 1 and the insulator body 2, and the connection strength is improved.
[0030] Furthermore, a support plate 9 is fixedly installed at the outer ring of the middle part of the column 1. A monitoring element 8 is installed on the support plate 9. The monitoring element 8 can monitor parameters such as stress, temperature and humidity of the glued structure 5, monitor the health status of the glued structure in real time, and provide early warning of potential problems.
[0031] It should be noted that the monitoring element 8 integrates a temperature sensor, a humidity sensor, and a pressure sensor. A reserved hole 7 is provided on the column 1 for connecting wires to the monitoring element 8. The reserved hole 7 is connected to the interior of the column 1, and the wires are connected to the outside through the interior of the column 1.
[0032] refer to Figure 3 As shown, a rubber sealing ring 6 is also fixedly installed on the outer ring of the threaded ring 4 made of adhesive material. The rubber sealing ring 6 has both a limiting function and a sealing function. It can be used to indicate the screw-in depth of the threaded ring 4 made of adhesive material and seals both sides of the adhesive channel to prevent the adhesive material from leaking. The structure is simple and practical.
[0033] It should also be noted that the threaded ring 4 and the adhesive structure 5 are both made of the same adhesive material, such as concrete or hot melt adhesive. This ensures that the strength and thermal expansion coefficient of the adhesive structure between the column 1 and the insulator body 2 are consistent, making it less likely to cause expansion cracking or delamination.
