Description

Technical Field

[0001] The utility model relates to the technical field of pillar porcelain insulators, in particular to a rigid pillar porcelain insulator. Background Art

[0002] Post insulators are a special type of insulating control that can play an important role in overhead transmission lines. They are usually made of ceramic, rubber or glass and have the advantages of high temperature resistance, wear resistance, corrosion resistance and oxidation resistance. Insulators play two basic roles in overhead transmission lines, namely supporting the conductors and preventing the current from returning to the ground. Currently, there are many types of rigid post porcelain insulators available on the market, but there are still some disadvantages.

[0003] The existing rigid pillar porcelain insulator increases the service life of the insulator by setting a wear-resistant layer. Generally, the insulator can only connect one type of cable, but the cables are of different thicknesses, so the insulator design has limitations. At the same time, since the insulator is installed at high altitude, birds often perch on it. The frequent perching and movement of birds will bring safety hazards to the insulator. Secondly, once the insulator is damaged, it will be troublesome to disassemble and replace it, and it will also be troublesome to install and fix it. For example, the Chinese utility model patent with authorization announcement number CN220400326U discloses a pillar porcelain insulator including an equal-diameter umbrella, the upper end of the equal-diameter umbrella is fixedly connected to an upper accessory wire clamp, the upper end of the upper accessory wire clamp is fixedly connected to a return line pressure plate, a fixing groove is fixedly connected between the upper accessory wire clamp and the return line pressure plate, the lower end of the equal-diameter umbrella is fixedly connected to a lower accessory connecting channel steel, and the lower end of the lower accessory connecting channel steel is slidably connected to a fixing rod. In the utility model, the high-speed railway contact network return line adopts equal-diameter umbrellas, which belong to type A non-breakdown type support insulators. Type A non-breakdown type support insulators can avoid the equal-diameter umbrellas being easily broken down and bursting under overvoltage conditions, effectively solving the problem of short circuit caused by the breakdown and bursting of porcelain insulators of the high-speed railway contact network return line. At the same time, the service life of the equal-diameter umbrellas is also improved, and the wires can be prevented from falling off and being unusable due to the bursting of the equal-diameter umbrellas. The wear-resistant layer can enhance the service life of the equal-diameter umbrellas. However, this device is provided with a wear-resistant layer to increase the service life of the insulator. Generally, insulators can only connect one type of cable, but the cables are of different thicknesses, so the insulator design has limitations. At the same time, since the insulators are installed at high altitudes, birds often inhabit them. The frequent inhabitation and movement of birds will bring safety hazards to the insulators. Secondly, once the insulators are damaged, it will be troublesome to disassemble and replace, and it will be troublesome to install and fix. Therefore, we propose rigid support porcelain insulators to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:

[0032] Embodiment 1: To solve the problems existing in the prior art, the present embodiment adopts the following technical solutions. A rigid support porcelain insulator is provided with an insulator support 1; a cable clamping mechanism capable of clamping cables of different thicknesses is arranged above the insulator support 1, which can clamp and fixedly connect cables of different thicknesses, greatly improving the practicality of the insulator design; a bird repelling mechanism is arranged on the left and right sides inside the mounting plate 9, which has rotatable blades and can effectively repel birds, avoiding potential safety hazards to the insulator; a convenient installation mechanism is arranged on the left and right sides of the mounting plate 9, which can adjust the installation and fixing position of the insulator support 1 and is also convenient for disassembly and replacement of the insulator support 1.First, the insulator post 1 is snap-fitted and installed between the fixed bottom plate 2 and the fixed top plate 5. Since the movable plates 13 are provided on the left and right sides of the mounting plate 9, the position of the insulator post 1 can be fixed. At the same time, the second threaded rod 20 can be rotated. Since the handle 19 and the mounting plate 9 are fixedly installed by the second threaded rod 20, first loosen the handle 19 and remove the handle 19, then the second threaded rod 20 can be rotated. The second threaded rod 20 is fixedly installed at the inner end of the first threaded rod 16, that is, the first threaded rod 16 will rotate. The outer end of the first threaded rod 16 is connected to the movable plate 13. In addition, a movable block 17 is provided on the outer side of the first threaded rod 16. The front side of the movable block 17 is located inside the fixed groove 18, and the fixed groove 18 is fixedly connected to the mounting plate 9. That is, when the first threaded rod 16 rotates, the movable plate 13 can be pushed to move outward. At this time, the movable block 17 will slide outward inside the fixed groove 18. The movable plate 13 can be adjusted according to the position of the fixedly installed insulator. At the same time, sliding blocks 14 are symmetrically installed on the left and right sides of the front side of the mounting plate 9. A fixed frame 15 is slidably arranged inside the sliding block 14, and the outer side of the fixed frame 15 is fixedly connected to the movable plate 13. That is, when the movable plate 13 moves, the fixed frame 15 will slide inside the sliding block 14, which can play a role in stabilizing the movement of the movable plate 13. Secondly, bird repellers 10 are snap-fitted at the left and right ends inside the mounting plate 9. The outer side below the bird repeller 10 is connected to an elastic cord 11. The elastic cord 11 has elasticity and can play a limiting role for the bird repeller 10. And a cylindrical pin 12 is arranged inside the elastic cord 11 for support. Secondly, a fixed bottom plate 2 is installed above the insulator post 1. A support column 3 is arranged diagonally above the fixed bottom plate 2. The outer side of the support column 3 is slidably connected to a fixed top plate 5. The fixed top plate 5 is located above the fixed bottom plate 2. At the same time, a spring 4 is arranged on the outer side of the support column 3. The spring 4 is fixedly connected to the upper part of the support column 3 and the upper part of the fixed top plate 5. That is, when the fixed top plate 5 is pulled by hand, the spring 4 will contract. The cable can be inserted into the fixed teeth 7 arranged inside the fixed bottom plate 2 and the fixed top plate 5, and then the fixed top plate 5 is released. Immediately, the spring 4 will rebound, and the fixed top plate 5 and the fixed bottom plate 2 will clamp and fix cables of different thicknesses. In addition, a connecting rod 8 is installed on the outer side of the fixed bottom plate 2. The fixed bottom plate 2, the fixed top plate 5, the fixed teeth 7, etc. are installed on both sides of the outer side of the connecting rod 8, which can further strengthen the connection and fixation of the cable. After the cable is clamped, the bolt 6 is inserted into the inner sides of the fixed bottom plate 2 and the fixed top plate 5 to further stabilize it.

[0033] For the existing rigid post porcelain insulators, generally only one type of cable can be connected through an insulator. However, due to different cable thicknesses, there are limitations in the insulator design, which is rather troublesome. Therefore, in this embodiment, the following technical solutions are adopted, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, the cable clamping mechanism capable of clamping cables with different thicknesses includes a fixed bottom plate 2 arranged above the insulator post 1. Support columns 3 are fixedly installed diagonally above the fixed bottom plate 2. At the same time, springs 4 are arranged outside the support columns 3. In addition, the upper part of the spring 4 is fixedly connected to the support column 3, and the spring 4 is connected to the fixed top plate 5. Secondly, fixed teeth 7 are equidistantly installed inside the middle parts of the fixed bottom plate 2 and the fixed top plate 5. That is, the cable to be connected is placed inside the middle parts of the fixed bottom plate 2 and the fixed top plate 5. At this time, the fixed top plate 5 will move upward, and the spring 4 will contract. After the cable is placed in, the fixed top plate 5 can be released. At this time, the spring 4 will rebound and can push the fixed top plate 5 to move downward to fit with the fixed bottom plate 2. Secondly, the fixed bottom plate 2, the fixed top plate 5, and the fixed teeth 7 are symmetrically installed before and after on the outside of the fixed bottom plate 2 and the fixed top plate 5, etc., which can increase the area of clamping and fixing the cable, thereby improving the stability of cable connection.

[0034] Embodiment 2: For the existing rigid post porcelain insulators, since the insulators are installed at high altitudes, birds often perch on them. The frequent perching and walking of birds will cause potential safety hazards to the insulators. Therefore, in this embodiment, through the following technical solutions, as Figure 1 , Figure 4 and Figure 6 shown, the bird repelling mechanism includes bird repellers 10 arranged on the left and right sides of the mounting plate 9. The outer side below the bird repeller 10 is connected to an elastic cord 11. The middle part of the elastic cord 11 is fixedly connected to a cylindrical pin 12 installed below the middle part of the mounting plate 9, that is, the elastic cord 11 has elasticity and can fix the position of the mounted mounting plate 9. When the bird repeller 10 is started, it can disperse the birds.

[0035] Embodiment 3: For the existing rigid post porcelain insulators, they cannot be applied to different installation positions. Therefore, in this embodiment, through the following technical solutions, as Figure 2 , Figure 5 and Figure 6 shown, the installation facilitating mechanism includes moving plates 13 arranged on the left and right sides of the mounting plate 9. First threaded rods 16 are symmetrically arranged on the left and right sides at the rear of the moving plates 13. The outer ends of the first threaded rods 16 are fixedly connected to the moving plates 13. That is, hold the handle 19 connected to the inner end of the first threaded rod 16 and rotate it. When the first threaded rod 16 rotates, a moving block 17 arranged on the outside of the first threaded rod 16 will slide on the outside of the first threaded rod 16, and the front side of the moving block 17 is located inside a fixed groove 18. The fixed groove 18 is fixedly connected to the mounting plate 9. That is, the fixed groove 18 will limit the movement of the moving block 17, enabling the moving block 17 to slide normally. The moving block 17 is fixedly connected to the moving plate 13. That is, when the moving block 17 moves outward, it can push the moving plate 13 to also move outward, expanding the installation area of the moving plate 13.
