Description

Technical Field

[0001] This utility model relates to the field of insulator technology, specifically to an insulator that provides positioning stability and prevents erosion and loss. Background Technology

[0002] An insulator is an insulating device used in power systems to support conductors and prevent current backflow. It is widely used in transmission lines, substations and other applications. Its core function is to achieve a balance between mechanical support and electrical insulation to ensure the safe and stable operation of the power system. Traditional insulators are usually composed of sheds and connecting rods. The insulation requirements for different voltage levels are achieved through the series connection of multiple sheds.

[0003] However, existing insulators suffer from the following problems during long-term use: First, the connection structure between the sheds is relatively fixed, making it difficult to adapt to angle changes and displacement adjustments in complex environments, leading to mechanical stress concentration and easy local wear or breakage; second, traditional connection methods lack effective anti-loosening and limiting mechanisms, making them prone to loosening or falling off under external dynamic loads such as wind and vibration, affecting the overall stability and service life of the insulator; in addition, the existing insulator assembly process is cumbersome, making it difficult to flexibly adjust the number of sheds according to site requirements, reducing the efficiency of construction and maintenance. Therefore, a limiting, stable, and corrosion-resistant insulator is needed to address the shortcomings of the existing ones. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to compensate for the lack of effective anti-loosening and limiting mechanisms in existing connection methods, which makes it easy for the connection to loosen or fall off under the action of external dynamic loads such as wind force and vibration, thus affecting the overall stability of the insulator.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an insulator with limited positioning, stability, and anti-corrosion and loss protection, comprising several umbrella discs, a connecting rod fixedly connected to the center of each umbrella disc, a set of symmetrical guide cylinders arranged between the umbrella discs, a connecting assembly movably connected to the opposite sides of the guide cylinders, a positioning block fixedly connected to the center of the end of each guide cylinder, positioning holes opened at both ends of each connecting rod, and the positioning block matching the positioning holes, a clamping assembly provided on the guide cylinder, several limiting holes opened on the outer sides of both ends of each connecting rod, and the clamping assembly connected to the limiting holes.

[0008] Furthermore, the connecting assembly includes a movable block, a return spring, a connecting block, and a universal joint. Both ends of the universal joint are fixedly connected to the connecting block, and the other end of the connecting block is rotatably connected to the movable block. The other end of the movable block is fixedly connected to the return spring.

[0009] Furthermore, the movable block is movably engaged inside the guide cylinder, and the end of the return spring away from the movable block is fixedly connected to the inside of the guide cylinder.

[0010] Furthermore, the clamping assembly includes a drive disk, a clamping block, a guide block, and a drive column. The drive disk has several drive slots arranged in a circular array. The inner side of each drive slot is movably connected to a drive column. The end of each drive column is fixedly connected to a guide block, and the other end of the guide block is fixedly connected to a clamping block.

[0011] Furthermore, the drive disc is rotatably connected to the inside of the guide cylinder, the end of the guide cylinder is provided with several guide grooves, and the guide blocks are slidably engaged with the inside of the guide grooves respectively, and the ends of the clamping blocks are respectively adapted to the limiting holes.

[0012] Furthermore, the clamping assembly also includes a synchronizing rod and an adjusting ring. Several synchronizing rods are fixedly connected to the outer side of the drive disk, and the synchronizing rods are distributed in a circular array. The synchronizing rods all movably penetrate the wall of the guide cylinder. The adjusting ring is movably sleeved on the outer side of the guide cylinder, and the end of the synchronizing rod away from the drive disk is fixedly connected to the inner side of the guide cylinder.

[0013] Furthermore, a toothed ring is fixedly connected to the end of the adjusting ring, a control ring is threadedly connected to the outer side of the guide cylinder, and a toothed ring is movably connected to the outer side of the guide cylinder. One end of the toothed ring is engaged with the toothed ring, and the other end of the toothed ring is rotatably connected to the control ring.

[0014] Compared with existing technologies, this limiting, stabilizing, and erosion-resistant insulator has the following advantages:

[0015] I. This utility model, through the setting of the connecting component, allows the movable block to move inside the guide cylinder, and the connecting block to be rotatably connected to the movable block. The universal joint allows the two connecting blocks to rotate at any angle, which is conducive to realizing the swing of the two guide cylinders at any angle, and thus facilitates the angle change between the two umbrella discs. Under the action of the return spring, the umbrella discs can be displaced along the axial direction of the connecting rod, thereby reducing the impact force of the external environment on the umbrella discs and improving the flexibility of the connection between the umbrella discs.

[0016] II. This utility model uses a clamping assembly to connect the connecting rod to the guide cylinder by engaging the end of the clamping block with the limiting hole. Then, the control ring is rotated to push the second toothed ring along the outside of the guide cylinder until the first toothed ring and the second toothed ring mesh. At this point, the adjusting ring remains at the current angle and cannot rotate, thus completely fixing the connecting rod to the guide cylinder. By operating in sequence, the umbrella tray can be quickly attached, which is convenient and controllable by selecting the number of umbrella trays to be connected according to the needs of the site.

[0023] 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.

[0024] Example 1:

[0025] like Figure 1-4As shown, this utility model provides a technical solution: an insulator with limited positioning, stability, and anti-corrosion and loss protection, including several umbrella discs 1, a connecting rod 2 fixedly connected to the center of each umbrella disc 1, a set of symmetrical guide cylinders 3 arranged between the umbrella discs 1, a connecting component 4 movably connected to the opposite side of the guide cylinders 3, a positioning block 5 fixedly connected to the center of the end of the guide cylinder 3, positioning holes 6 opened at both ends of the connecting rod 2, and the positioning block 5 is adapted to the positioning hole 6, a clamping component 7 is provided on the guide cylinder 3, several limiting holes 8 are opened on the outer sides of both ends of the connecting rod 2, and the clamping component 7 is connected to the limiting holes 8.

[0026] By using the limiting component, the end of the connecting rod 2 is fixedly connected to the guide cylinder 3, thereby enabling the connection between the two insulators under the action of the connecting component 4.

[0027] Example 2:

[0028] like Figure 1 and Figure 3 As shown, the connecting assembly 4 includes a movable block 401, a return spring 402, a connecting block 403, and a universal joint 404. Both ends of the universal joint 404 are fixedly connected to the connecting block 403, and the other end of the connecting block 403 is rotatably connected to the movable block 401. The other end of the movable block 401 is fixedly connected to the return spring 402. The movable block 401 is movably engaged inside the guide cylinder 3, and the end of the return spring 402 away from the movable block 401 is fixedly connected to the inside of the guide cylinder 3.

[0029] The movable block 401 moves inside the guide cylinder 3, and the connecting block 403 is rotatably connected to the movable block 401. The universal joint 404 allows the two connecting blocks 403 to rotate at any angle, which is conducive to realizing the swing of the two guide cylinders 3 at any angle, and thus facilitates the angle change between the two umbrella discs 1. Under the action of the return spring 402, the umbrella discs 1 can be displaced along the axial direction of the connecting rod 2, thereby reducing the impact force of the external environment on the umbrella discs 1 and improving the flexibility of the connection between the umbrella discs 1.

[0030] Example 3:

[0031] like Figure 1 and Figure 4As shown, the clamping assembly 7 includes a drive disk 701, a clamping block 702, a guide block 703, and a drive post 704. The drive disk 701 has several drive grooves 9 arranged in a circular array. Each drive groove 9 has a drive post 704 movably connected to its inner side. A guide block 703 is fixedly connected to the end of each drive post 704, and a clamping block 702 is fixedly connected to the other end of each guide block 703. The drive disk 701 is rotatably connected to the interior of a guide cylinder 3. Several guide grooves 10 are formed at the end of the guide cylinder 3, and the guide blocks 703 slide within each guide groove 10. The ends of the clamping blocks 702 are respectively adapted to the limiting holes 8. The clamping assembly 7 also includes a synchronous... A rod 705 and an adjusting ring 706 are fixedly connected to the outer side of the drive disc 701. Several synchronizing rods 705 are arranged in a circular array. All synchronizing rods 705 movably penetrate the cylinder wall of the guide cylinder 3. The adjusting ring 706 is movably sleeved on the outer side of the guide cylinder 3. The end of the synchronizing rod 705 away from the drive disc 701 is fixedly connected to the inner side of the guide cylinder 3. A toothed ring 11 is fixedly connected to the end of the adjusting ring 706. A control ring 13 is threadedly connected to the outer side of the guide cylinder 3. A toothed ring 12 is movably connected to the outer side of the guide cylinder 3. One end of the toothed ring 12 meshes with the toothed ring 11, and the other end of the toothed ring 12 is rotatably connected to the control ring 13.

[0032] First, insert the positioning block 5 at the end of the guide cylinder 3 into the positioning hole 6 at the end of the connecting rod 2. Then, rotate the adjusting ring 706. Under the action of the synchronizing rod 705, the driving disc 701 rotates inside the guide cylinder 3. Since the driving column 704 is in movable cooperation with the driving groove 9, and the guide block 703 is in sliding cooperation with the guide groove 10, the guide block 703 moves along the guide groove 10 closer to the connecting rod 2 until the end of the clamping block 702 is locked inside the limiting hole 8, thereby connecting the connecting rod 2 and the guide cylinder 3. Then, rotate the control ring 13 to push the toothed ring 12 to move along the outside of the guide cylinder 3 until the toothed ring 11 and the toothed ring 12 mesh. At this time, the adjusting ring 706 remains at the current angle and cannot rotate, thereby completely fixing the connecting rod 2 to the guide cylinder 3. By operating in sequence, the umbrella tray 1 can be quickly attached, which is convenient and controllable for selecting the number of umbrella trays 1 to be connected according to the needs of the site.
