Description

Technical Field

[0001] This application relates to the technical field of insulators, and in particular to an insulator with a warning label. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a component at ground potential. It can withstand voltage and mechanical stress. An insulator is a special insulating control that plays an important role in overhead transmission lines. It consists of two main parts: insulating components and connecting hardware. In the early days, insulators were mostly used on utility poles. Gradually, they were developed into high-voltage power line connecting towers. Many disc-shaped insulators are hung at one end to increase the creepage distance. They are usually made of glass or ceramic and are called insulators. Insulators can be divided into suspension insulators and post insulators according to different installation methods. According to the different insulating materials used, they can be divided into porcelain insulators, glass insulators, and composite insulators. According to different voltage levels, they can be divided into low-voltage insulators and high-voltage insulators.

[0003] A search revealed Chinese Patent Publication No. CN220672303U, which discloses a composite insulator with warning markings. The insulator includes a core rod, a sheath, skirts, and metal accessories. The metal accessories for connection are located at both ends of the core rod. The skirts near the metal accessories are designated as large skirts, with a diameter larger than the inner skirts. A warning marking area is provided on the surface of the large skirt facing the fixed rod. This composite insulator with warning markings integrates the warning marking area on the large skirt at the ends, avoiding the need for separate markings, improving safety performance, and reducing maintenance and installation costs.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing signboards 4 are often metal signboards, which require separate installation. Due to wind, long-term shaking can easily loosen the screws, causing them to fall and pose a safety hazard. In addition, the hanging location is not convenient for installation, and because there is no obvious marking after damage, it is not easy for inspection and maintenance personnel to find the damaged insulators, which poses a hidden danger to the safe operation of the distribution network. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides an insulator with a warning label.

[0006] This application provides an insulator with a warning label, employing the following technical solution: It includes an insulator body, an adjusting cover rotatably connected to the top outer surface of the insulator body, a power mechanism located inside the insulator body at the top center of the adjusting cover, and an adjusting mechanism at the top of the adjusting cover. The adjusting mechanism includes a limiting disc, with two electromagnets embedded inside the bottom of the limiting disc. Each electromagnet contains a power failure sensing module. A power supply battery connected to the electromagnets is embedded in the limiting disc. A positioning rod is fixedly connected to the bottom wall of the limiting disc near the electromagnets, and the electromagnets and positioning rods are connected by a wire. The power mechanism includes a pushing ring, with two pushing rings arrayed at the center of the adjusting cover. A guide ring is slidably connected between the pushing rings. A fixing block is fixedly connected to the end of the guide ring away from the pushing ring. A tension spring is sleeved on the outer surface of the guide ring between the fixing block and the pushing ring, with both ends of the tension spring fixedly connected to the side wall of the fixing block and the pushing ring, respectively.

[0007] Optionally, the outer wall array of the insulator body is provided with a number of warning reflective stickers, the color of which is red, and the side wall array of the adjustment cover is provided with the same number of light-shielding stickers as the warning reflective stickers.

[0008] Optionally, the top wall of the insulator body is provided with a rotating groove that engages with the adjusting cover. The adjusting cover is made of transparent material. An installation groove is provided at the center of the top of the insulator body. The fixed block is connected to the bottom wall of the installation groove by bolts. A docking platform is fixedly connected at the center of the installation groove.

[0009] Optionally, the top wall of the docking platform is provided with a positioning hole that engages with the positioning rod. A conductive wire is embedded in the positioning hole. The conductive wire is embedded in the insulator body in a ring shape. The top of the conductive wire contacts the positioning rod through a metal ring. The positioning rod is made of metal.

[0010] Optionally, a docking hole is provided at the center of the docking platform, and a thread is provided on the inner wall of the docking hole. An additional frame is provided on the top of the limiting plate, and the bottom of the additional frame is connected to the docking hole by a screw. A hanging rod that meshes with the top of the additional frame is fixedly connected to the center of the bottom wall of the insulator body.

[0011] Optionally, the limiting plate has a through hole inside, and the screw at the bottom of the additional frame forms a sliding connection with the through hole.

[0012] Optionally, the center of the adjusting cover has a notch that engages with the mounting groove, a limit ring is fixedly connected to the top wall of the adjusting cover near the notch, and a limit groove that engages with the limit ring is provided on the bottom wall of the limit plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by setting up an electromagnet, a positioning rod, a positioning hole, and a conductive wire, and through the cooperation between the positioning rod and the conductive wire, allows the electromagnet to receive a signal of conductive wire breakage through an internal power failure sensing module. By setting up a pushing ring and a tension spring, the contraction of the electromagnet causes the pushing ring to disengage from its limit position, and the adjusting cover rotates under the action of the tension spring, thereby achieving the effect of the light-blocking sticker detaching from the warning reflective sticker and realizing the warning function.

[0015] 2. This utility model uses a fixing block and bolts to fix the pushing ring and guide ring in the mounting groove, thus connecting the adjusting cover and the insulator body. By manually rotating the adjusting cover counterclockwise by a certain angle, the limiting plate is connected to the top of the adjusting cover. After the positioning rod is inserted into the positioning hole, the electromagnet drives the internal iron rod to extend, thereby limiting the position of the pushing ring. Through the cooperation between the added frame and the docking hole, the limiting plate is fixed to the upper end of the adjusting cover, thus achieving the effect of easy assembly.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses an insulator with a warning label. For example... Figure 1 As shown, the device includes an insulator body 1. An adjustment cover 2 is rotatably connected to the top outer surface of the insulator body 1. The adjustment cover 2 is made of transparent material. A power mechanism is located inside the insulator body 1 at the top center of the adjustment cover 2. An adjustment mechanism is located on the top of the adjustment cover 2. The adjustment mechanism includes a limit plate 3. Two electromagnets 4 are embedded inside the bottom of the limit plate 3. A power failure sensing module is installed inside the electromagnets 4. A power supply battery connected to the electromagnets 4 is embedded in the limit plate 3. A positioning rod 5 is fixedly connected to the bottom wall of the limit plate 3 near the electromagnets 4. The electromagnets 4 and the positioning rod 5 are connected by a wire. The power mechanism includes a push ring 6. Two push rings 6 are arranged in an array at the center of the adjustment cover 2. A guide ring 7 is slidably connected between the push rings 6. A fixing block 8 is fixedly connected to the end of the guide ring 7 away from the push ring 6. A tension spring 9 is sleeved on the outer surface of the guide ring 7 between the fixing block 8 and the push ring 6. The guide ring 7 limits the tension spring 9. The two ends of the tension spring 9 are fixedly connected to the side wall of the fixing block 8 and the push ring 6, respectively.

[0027] Please see Figure 3The outer wall of the insulator body 1 is arrayed with several warning reflective stickers 10, which are red in color. This arrangement facilitates ground personnel to observe the usage status of the insulator body 1. The side wall of the adjusting cover 2 is arrayed with the same number of light-shielding stickers 11 as the warning reflective stickers 10. When the insulator body 1 is in good working condition, the light-shielding stickers 11 block the warning reflective stickers 10. The top wall of the insulator body 1 has a rotating groove that engages with the adjusting cover 2. This arrangement facilitates the adjusting cover 2 to fit the insulator body 1. The top center of the insulator body 1 has a mounting groove 12. The fixing block 8 is connected to the bottom wall of the mounting groove 12 by bolts. This arrangement facilitates the connection between the adjusting cover 2 and the insulator body 1. A docking platform 13 is fixedly connected to the center of the mounting groove 12.

[0028] Please see Figure 4 The top wall of the docking platform 13 has a positioning hole 14 that engages with the positioning rod 5. A conductive wire 15 is embedded in the positioning hole 14. The conductive wire 15 is embedded in the insulator body 1 in a ring shape. The top of the conductive wire 15 contacts the positioning rod 5 through a metal ring. The positioning rod 5 is made of metal and serves to conduct electricity and limit movement. A docking hole 16 is provided at the center of the docking platform 13. The inner wall of the docking hole 16 is threaded. An extension frame 17 is provided on the top of the limiting plate 3. The bottom of the extension frame 17 is connected to the docking hole 16 through a screw. When the extension frame 17 is fully engaged with the docking hole 16, a gap is left between the top of the adjusting cover 2 and the bottom wall of the limiting plate 3. This setting facilitates the flexible rotation of the adjusting cover 2. A hanging rod 18 that engages with the top of the extension frame 17 is fixedly connected at the center of the bottom wall of the insulator body 1.

[0029] Please see Figure 5 The limiting plate 3 has a through hole inside. The screw at the bottom of the bracket 17 forms a sliding connection with the through hole. The center of the adjusting cover 2 has a notch that engages with the mounting groove 12. The top wall of the adjusting cover 2 is fixedly connected to the notch. The bottom wall of the limiting plate 3 has a limiting groove that engages with the limiting ring 19. The limiting groove plays a positioning role for the limiting ring 19.

[0030] The implementation principle of an insulator with a warning label in this application embodiment is as follows: When the insulator body 1 breaks during use, the conductive wire 15 inside it breaks. At this time, the electromagnet 4 senses the power failure information through the positioning rod 5. The electromagnet 4 drives the internal iron rod to retract, pushing the ring 6 away from the limit of the electromagnet 4. Under the action of the tension spring 9, the pushing ring 6 drives the adjustment cover 2 to rotate. The adjustment cover 2 drives the light shielding sticker 11 away from the warning reflective sticker 10. At this time, the usage status of the insulator body 1 can be identified through the warning reflective sticker 10.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
