Description

Technical Field

[0001] This utility model relates to the field of porcelain insulator technology, specifically to a porcelain insulator that prevents detachment. Background Technology

[0002] Porcelain insulators are used in high-voltage transmission and distribution lines to insulate and support conductors. There are various types of porcelain insulators, among which the pin-type porcelain insulator is one type. It consists of insulating components and steel feet and is installed on supporting structures for use.

[0003] In traditional pin-type insulators, the upper end of the insulating component is connected and fixed to the conductor via a binding wire, while the steel foot is fixed to the supporting structure. This fixing method can easily cause the fixed ends at both ends to loosen and detach when exposed to strong winds for extended periods. This results in low overall protection and safety for the porcelain insulator. Therefore, we have proposed an anti-detachment porcelain insulator to address the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a porcelain insulator that is resistant to detachment, in order to solve the problem mentioned in the background art that the porcelain insulators currently on the market are prone to loosening at both ends when exposed to strong winds, resulting in detachment and low overall protection and safety of the porcelain insulators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a porcelain insulator that prevents detachment, comprising an insulating component, wherein the upper end of the insulating component is connected to a conductor via a binding wire, the lower end of the insulating component is connected to a steel foot, and a support component is sleeved on the outer side of the steel foot;

[0006] A mounting bracket is fitted on the outside of the wire, and the mounting bracket is locked to the wire by bolts. A support ring is installed at the lower end of the mounting bracket, and a sliding groove is opened on the lower side of the support ring. A slider is slidably connected inside the sliding groove, and a protective rod is installed at the lower end of the slider.

[0007] The inner side of the slide is provided with positioning holes;

[0008] An adjusting rod is slidably connected inside the protective rod. An extension rod is connected to the outer side of the lower section of the adjusting rod. A positioning frame is installed at the upper end of the adjusting rod. Nuts are threadedly connected to the outer sides of both the adjusting rod and the steel foot.

[0009] Preferably, the mounting bracket has a "U" shaped structure and is symmetrically arranged about the longitudinal center line of the support ring.

[0010] Preferably, the slider has a "T" shaped structure and is slidably connected to the support ring by passing through the lower wall of the support ring.

[0011] Preferably, the contact area between the protective rod and the insulating component is made of rubber, and the protective rod has three parts distributed at equal angles about the longitudinal center line of the support ring.

[0012] Preferably, the adjusting rod passes through the support member, the adjusting rod and the extension rod are distributed perpendicularly to each other, and both the adjusting rod and the extension rod slide through the protective rod.

[0013] Preferably, the positioning frame has an inverted "U" shaped structure, the positioning frame is slidably connected to the slider, and the positioning frame is engaged with the positioning hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The anti-detachment porcelain insulator can be moved by driving the protective rod to make the protective rod fit against the edge of the insulator, press the side of the insulator, and reinforce the insulator. The protective rods distributed at equal angles can evenly reinforce the insulator and prevent the insulator from being blown by strong winds and causing the connection end to loosen.

[0016] (2) The anti-detachment porcelain insulator can achieve synchronous locking of the protective rod and the slider by driving the adjustment rod to move, so that it can be adapted to different types of porcelain insulators for pressure support, improving the convenience and flexibility of its operation, and the protective performance and safety of the porcelain insulator are improved by using this structure.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a porcelain insulator that is detachable, comprising an insulating component 1, an upper end of the insulating component 1 being connected to a conductor 3 via a binding wire 2, a lower end of the insulating component 1 being connected to a steel foot 4, and a support component 5 being sleeved on the outer side of the steel foot 4;

[0026] A mounting bracket 6 is fitted on the outer side of the wire 3. The mounting bracket 6 is locked to the wire 3 by bolts. A support ring 7 is installed at the lower end of the mounting bracket 6. A sliding groove 8 is opened on the lower side of the support ring 7. A slider 9 is slidably connected inside the sliding groove 8. A protective rod 10 is installed at the lower end of the slider 9.

[0027] Furthermore, the mounting bracket 6 has a "U" shaped structure. The mounting bracket 6 is symmetrically arranged about the longitudinal center line of the support ring 7. The support ring 7 is fixed by locking the mounting bracket 6 with the wire 3, so that the protective rod 10 can be located outside the insulating component 1.

[0028] Furthermore, the slider 9 has a "T" shaped structure. The slider 9 passes through the lower wall of the support ring 7 and is slidably connected to the support ring 7. The slider 9 can be used to limit the movement of the protective rod 10, ensuring the stable movement of the protective rod 10 and preventing the slider 9 from detaching from the support ring 7.

[0029] Furthermore, the contact point between the protective rod 10 and the insulating component 1 is made of rubber. The protective rod 10 has three angles distributed at equal angles about the longitudinal center line of the support ring 7, which allows the protective rod 10 to fit tightly with the insulating component 1 and allows the protective rod 10 to press and reinforce the insulating component 1 at the triangular position.

[0030] The inner side of the slide 8 is provided with a positioning hole 13; the inside of the protective rod 10 is slidably connected with an adjusting rod 11, the outer side of the lower section of the adjusting rod 11 is connected with an extension rod 12, the upper end of the adjusting rod 11 is equipped with a positioning frame 14, and the outer sides of the adjusting rod 11 and the steel foot 4 are both threaded with nuts 15.

[0031] Furthermore, the adjusting rod 11 passes through the support member 5. The adjusting rod 11 and the extension rod 12 are perpendicular to each other. Both the adjusting rod 11 and the extension rod 12 slide through the protective rod 10. The movement of the adjusting rod 11 can be easily controlled by driving the extension rod 12 to move. The position of the protective rod 10 and the positioning frame 14 can be locked by locking the position of the adjusting rod 11.

[0032] Furthermore, the positioning frame 14 has an inverted "U" shaped structure. The positioning frame 14 is slidably connected to the slider 9, and the positioning frame 14 is engaged with the positioning hole 13. The positioning frame 14 is used to fix the position of the slider 9, so as to prevent the protective rod 10 from moving on its own when it is pressing against the insulating part 1 for protection.

[0033] Specifically, the steel foot 4 connected to the lower end of the insulating component 1 passes through the support component 5. The nut 15 on the steel foot 4 is rotated and moved on the threaded steel foot 4, so that the nut 15 fits against the support component 5, thus realizing the installation of the insulating component 1 and the support component 5. Then, the support ring 7 is put on the outside of the insulating component 1, and the wire 3 is placed in the groove at the upper end of the insulating component 1 and in the mounting bracket 6. The mounting bracket 6 and the wire 3 are locked with bolts, and the wire 3 is locked to the end of the insulating component 1 with the binding wire 2.

[0034] After the insulation component 1 is assembled, the relative positions of the support ring 7 and the insulation component 1 are determined. The protective rod 10 can then be pushed, causing the upper end of the protective rod 10 to slide within the groove 8. The position of the protective rod 10 is adjusted so that it fits tightly against the edge of the insulation component 1. At this point, the extension rod 12 can be moved to control the adjusting rod 11 to move downward. The lower end of the adjusting rod 11 passes through the pre-drilled hole in the support component 5. As the adjusting rod 11 moves downward, the positioning frame 14 installed at the upper end can be moved downward, causing the positioning frame 14 to engage in the positioning hole 13 and lock the position of the slider 9, thereby locking the position of the protective rod 10. The nut 15 is threaded onto the lower end of the adjusting rod 11. The nut 15 is rotated, causing it to move upward while rotating until it fits against the support component 5, thus stabilizing the position of the protective rod 10. The protective rods 10, distributed at equal angles, can reinforce the porcelain insulator and prevent its connection from loosening. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
