Description

Technical Field

[0001] This invention belongs to the field of insulators, specifically relating to a composite post insulator structure that can protect against lightning. Background Technology

[0002] Compared to traditional porcelain post insulators, composite structures have the advantages of superior mechanical strength and light weight. Furthermore, compared to the metal flanges of insulators, composite structures increase the arc distance, effectively preventing electrical breakdown and thus achieving lightning protection.

[0003] Patent CN206711683U relates to an insulator structure, comprising: an insulator body, which includes an insulator cover and an insulator core; the insulator core is disposed inside the insulator cover and extends outward from the centerline of the insulator cover; the insulator core has an anti-creep groove structure, forming a cavity between the anti-creep groove structure and the inner wall of the insulator cover. This patent provides a sufficiently long creepage distance for the insulator cover, prevents dust accumulation on the insulator core inside the insulator cover, and separates the insulator cover and the insulator core through the anti-creep groove structure, preventing current from being transmitted to the insulator core, effectively preventing creepage. Furthermore, this insulator structure is simple, rationally designed, low-cost, and highly effective.

[0004] In the aforementioned patent, the anti-creep groove structure separates the insulator, preventing current from being transmitted to the insulator core and effectively preventing creepage. However, during installation, the insulator is only supported by manpower and not properly secured. In this case, even slight external forces such as strong winds or collisions during operation can directly cause the insulator to tip over. At the same time, if the sealing gasket is not properly fitted, rainwater can seep into the insulator, accelerating its overall aging. Furthermore, the vibrations from strong winds during outdoor operation can be continuously transmitted to the insulator, causing the connection points to loosen. Therefore, it is necessary to design a composite support insulator structure that can protect against lightning to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a composite post insulator structure that can protect against lightning, in order to solve the problem that if the insulator is only supported by manpower during the installation process and is not properly secured, it will directly cause the insulator to tip over when it is subjected to slight external forces such as strong winds or collisions during operation.

[0006] To achieve the above objectives, the present invention provides a lightning-proof composite post insulator structure, including a base and an installation assembly. An insulator body is mounted on the top of the base, and a composite connector and a composite flange are provided on the circumferential surface of the insulator body. The installation assembly includes an installation plate, an elastic telescopic block, an anti-tilt groove, an installation hole, a shielding plate, a shielding spring, and a connecting block. The installation plate is fixedly mounted on the top of the base, and the elastic telescopic block is fixedly mounted on the top of the installation plate. The anti-tilt groove is formed on the circumferential surface of the composite flange, and the installation hole is formed on the right side of the composite flange. The shielding plate is slidably mounted on the right side of the composite flange, and the shielding spring is disposed between the composite flange and the shielding plate. The connecting block is disposed between the base and the installation plate. The elastic telescopic block is used to limit the movement of the composite flange, the shielding plate is used to shield the installation hole, and the composite flange is used to install the insulator body. When the free end of the elastic telescopic block moves rearward, it contacts the inner wall of the anti-tilt groove and limits the movement of the composite flange. The contact between the free end of the elastic telescopic block and the inner wall of the anti-tilt groove forms a limiting effect.

[0007] In one or more embodiments of the present invention, the rear side of the elastic telescopic block is set as an inclined surface. By setting the rear side of the elastic telescopic block as an inclined surface, the frictional force when the elastic telescopic block contacts the composite flange can be reduced. The free end of the elastic telescopic block contacts the inner wall of the anti-tilt groove, and the composite flange contacts the top of the base. If the placement angle of the insulator body is deviated, the insulator body can be slightly rotated. Rotating the insulator body will drive the composite flange to rotate. The rotation of the composite flange can make the anti-tilt groove and the free end of the elastic telescopic block aligned without the need to re-lift or disassemble the insulator body.

[0008] In one or more embodiments of the present invention, the shielding plate contacts the top of the base, the connecting block is used to connect the mounting plate and the base, the mounting hole is used to connect with an external mounting component, and the shielding plate moving to the right will release the obstruction of the mounting hole.

[0009] In one or more embodiments of the present invention, a sealing assembly and a support assembly are further included. The sealing assembly is used to improve the sealing performance of the insulator body, and the support assembly is used to provide auxiliary support for the insulator body. The sealing assembly includes a waterproof ring, a waterproof groove, a sealing arc rod, a limiting frame, a limiting block, a limiting groove, and an elastic telescopic rod. When the sealing arc rod moves to the right, it contacts the waterproof ring and squeezes the waterproof ring. The waterproof ring deforms under the squeezing of the sealing arc rod. The waterproof ring is disposed on the top of the composite flange. The waterproof groove is formed on the circumferential surface of the waterproof ring. The sealing arc rod is fixedly installed on the top of the baffle plate. The limiting frame is fixedly installed on the rear side of the sealing arc rod. The limiting block is disposed between the sealing arc rod and the limiting frame. The limiting groove is formed on the rear side of the composite flange. The elastic telescopic rod is fixedly installed on the inner wall of the limiting groove.

[0010] In one or more embodiments of the present invention, the top of the free end of the elastic telescopic rod is set as an inclined surface, the limiting frame is in contact with the composite flange, and the waterproof ring is made of rubber, so that the composite flange can be sealed by the waterproof ring being made of rubber.

[0011] In one or more embodiments of the present invention, the sealing arc rod contacts the composite flange, the sealing arc rod is used to compress the waterproof ring, the elastic telescopic rod is used to limit the sealing arc rod, the free end of the elastic telescopic rod moves upward and resets under its own elastic force, and the upward movement of the free end of the elastic telescopic rod will limit the limiting frame. With the limiting effect of the elastic telescopic rod, the sealing arc rod can form a continuous and uniform pressure on the waterproof ring.

[0012] In one or more embodiments of the present invention, the support assembly includes a speed control groove, a hollow frame, an adjusting plate, an arc ring, a support plate, and a support hole. The arc ring undergoes slow deformation, causing the adjusting plate to move slowly to the right. The slow movement of the adjusting plate to the right causes the sealing arc rod to move slowly to the right. The speed control groove is located at the top of the base. The hollow frame is fixedly installed on the inner wall of the speed control groove. The adjusting plate is slidably installed on the inner wall of the hollow frame. The arc ring is fixedly installed on the inner wall of the hollow frame. The support plate is slidably installed on the inner wall of the hollow frame. The support hole is located at the bottom of the insulator body. The adjusting plate drives the sealing arc rod to move slowly and uniformly.

[0013] In one or more embodiments of the present invention, a spring is provided between the support plate and the hollow frame, which can support the support plate. The adjusting plate contacts the sealing arc rod and the adjusting plate contacts the arc ring. When the support plate moves to the left, it contacts the support hole and provides auxiliary support to the insulator body.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes the rearward movement of the free end of the elastic telescopic block to contact the inner wall of the anti-tilt groove and limit the composite flange. The contact between the free end of the elastic telescopic block and the inner wall of the anti-tilt groove forms a limit, which can directly counteract the tipping and falling of the insulator body caused by strong winds or operational collisions, thereby reducing the risk of equipment damage during installation. If there is a deviation in the placement angle of the insulator body, the insulator body can be slightly rotated. The rotation of the composite flange will align the anti-tilt groove with the free end of the elastic telescopic block. There is no need to re-lift or disassemble the insulator body. By simply rotating the insulator body, the alignment and cooperation between the anti-tilt groove and the elastic telescopic block can correct the insulator body to the correct installation angle, greatly reducing the installation difficulties caused by angle deviation. Furthermore, the composite flange is lighter than the metal flange, which not only saves effort during installation but also has the characteristics of being non-conductive and rust-free.

[0015] 2. This invention removes the obstruction of the mounting hole by moving the shield to the right, effectively shielding the mounting hole before installation and preventing it from being bumped or deformed, thereby ensuring the smooth installation of the insulator body.

[0016] 3. This invention uses the deformation of the waterproof ring to fill the gap between the insulator body and the composite flange. After the waterproof ring deforms, it forms a full-fit seal with the gap, further sealing the connection gap between the insulator body and the composite flange, preventing rainwater or dew from entering from the source, thereby ensuring the sealing and waterproof performance of the insulator body.

[0017] 4. This invention, by limiting the free end of the elastic telescopic rod through the limiting frame, makes the sealing arc rod tightly adhere to the circumferential surface of the waterproof ring. With the limiting effect of the elastic telescopic rod, the sealing arc rod can form a continuous and uniform pressure on the waterproof ring, which can counteract the loosening of the sealing gap caused by thermal expansion and contraction, thereby achieving long-term sealing and further improving the waterproof performance of the insulator body.

[0018] 5. This invention, by slowly moving the adjusting plate to the right, causes the sealing arc to move slowly to the right, and the adjusting plate drives the sealing arc rod to move slowly and uniformly. This can avoid the excessive local stress on the waterproof ring caused by rigid and rapid compression, resulting in uneven deformation or even damage, thereby ensuring that the waterproof ring is uniformly attached to the insulator body and the composite flange in the circumferential direction.

[0019] 6. In this invention, the support plate moves to the left and contacts the support hole to provide auxiliary support for the insulator body. The auxiliary support can offset the stress caused by strong outdoor wind vibration, thereby reducing the loosening of the insulator body caused by long-term uneven stress and extending the service life of the insulator body.

[0022] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] Reference Figure 1-6 One embodiment of the present invention is: a composite post insulator structure capable of lightning protection, including a base 1 and an installation assembly. An insulator body 2 is disposed on the top of the base 1, a composite connector 3 is disposed on the circumferential surface of the insulator body 2, and a composite flange 4 is disposed on the circumferential surface of the insulator body 2. The installation assembly includes an installation plate 5, an elastic telescopic block 6, an anti-tilting groove 7, an installation hole 8, a shielding plate 9, a shielding spring 10, and a connecting block 11. The installation plate 5 is fixedly installed on the top of the base 1, the elastic telescopic block 6 is fixedly installed on the top of the installation plate 5, the anti-tilting groove 7 is formed on the circumferential surface of the composite flange 4, the installation hole 8 is formed on the right side of the composite flange 4, and the shielding plate 9 is slidably installed on the right side of the composite flange 4, providing shielding. Spring 10 is positioned between composite flange 4 and shielding plate 9, connecting block 11 is positioned between base 1 and mounting plate 5, elastic telescopic block 6 is used to limit composite flange 4, shielding plate 9 is used to shield mounting hole 8, composite flange 4 is used to install insulator body 2, the free end of elastic telescopic block 6 contacts the inner wall of anti-tilt groove 7 to form a limit, which can directly offset the tilting and falling of insulator body 2 caused by strong wind or operational collision, thereby reducing the risk of equipment damage during installation. In addition, composite flange 4 is made of non-metallic non-conductive material. The biggest advantage of this composite flange 4 is its strong insulation, flame retardancy and high temperature resistance, high mechanical strength and corrosion and moisture resistance, thus making it suitable for high and low voltage electrical scenarios.

[0024] Electrical advantages: high dielectric strength, low loss, arc resistance without breakdown, and excellent adaptability to various lightning protection and insulation scenarios; Weather and corrosion resistant: waterproof and moisture-proof, resistant to acid, alkali and salt spray, and not prone to aging and deformation after long-term outdoor use; Reliable mechanical components: high rigidity, impact resistance, high machining precision, and stable flange sealing fit; Flame retardant and safe: UL94V0 flame retardant rating, does not spontaneously combust at excessive temperatures, making it safer for use in electrical equipment; Lightweight: Lighter than metal flanges, easier to install, non-conductive and rust-free; Easy to process: Drilling and milling precision is easy to control, and composite insulator flange structure can be formed in one piece; For products of the same height, the increased dry arc distance compared to metal flanges effectively prevents electrical breakdown and thus achieves lightning protection.

[0025] The rear side of the elastic expansion block 6 is set as an inclined surface. By setting the rear side of the elastic expansion block 6 as an inclined surface, the friction force when the elastic expansion block 6 contacts the composite flange 4 can be reduced. The free end of the elastic expansion block 6 contacts the inner wall of the anti-tilt groove 7, and the composite flange 4 contacts the top of the base 1. If the placement angle of the insulator body 2 is deviated, the insulator body 2 can be slightly rotated. Rotating the insulator body 2 will drive the composite flange 4 to rotate. The rotation of the composite flange 4 can align the anti-tilt groove 7 with the free end of the elastic expansion block 6. There is no need to lift or disassemble the insulator body 2 again. By simply rotating the insulator body 2 slightly, the insulator body 2 can be corrected to the correct installation angle by utilizing the alignment and cooperation of the anti-tilt groove 7 and the elastic expansion block 6.

[0026] The shielding plate 9 contacts the top of the base 1. The connecting block 11 is used to connect the mounting plate 5 and the base 1. The mounting hole 8 is used to connect with external mounting parts. When the shielding plate 9 moves to the right, it will remove the shielding of the mounting hole 8. Before installation, the mounting hole 8 is effectively shielded to prevent it from being bumped and deformed, thereby ensuring the smooth installation of the insulator body 2.

[0027] During operation: When installing the insulator body 2, the insulator body 2 is placed on top of the base 1. During the process of placing the insulator body 2 on top of the base 1, it moves downward. The downward movement of the insulator body 2 causes the composite flange 4 to move downward. The downward movement of the composite flange 4 will contact the inclined surface of the elastic expansion block 6 and squeeze the free end of the elastic expansion block 6. The free end of the elastic expansion block 6 moves forward due to the squeezing of the composite flange 4. After the composite flange 4 moves downward to align the anti-tilt groove 7 with the free end of the elastic expansion block 6, the free end of the elastic expansion block 6 moves backward under its own elastic force. The backward movement of the free end of the elastic expansion block 6 will contact the inner wall of the anti-tilt groove 7 and limit the composite flange 4. If the placement angle of the insulator body 2 is deviated, the insulator body 2 can be slightly rotated. Rotating the insulator body 2 will drive the composite flange 4 to rotate. The rotation of the composite flange 4 will align the anti-tilt groove 7 with the free end of the elastic expansion block 6. At the same time, the insulator body 2 will be rotated to the correct installation angle. After the insulator body 2 is rotated to the correct installation angle, the baffle plate 9 will be pushed to the right. The baffle plate 9 moving to the right will pull the baffle spring 10. The baffle spring 10 will deform and store force due to the pull of the baffle plate 9. At the same time, the obstruction plate 9 will move to the right to remove the obstruction of the mounting hole 8. After the obstruction of the mounting hole 8 is removed, the composite flange 4 and the base 1 can be fixed by bolts and nuts, thereby completing the installation of the insulator body 2.

[0028] Reference Figure 1-7 Based on the above embodiments, another embodiment of the present invention further includes a sealing assembly and a support assembly. The sealing assembly is used to improve the sealing performance of the insulator body 2, and the support assembly is used to provide auxiliary support for the insulator body 2. The sealing assembly includes a waterproof ring 121, a waterproof groove 122, a sealing arc rod 123, a limiting frame 124, a limiting block 125, a limiting groove 126, and an elastic telescopic rod 127. The waterproof ring 121 is disposed on the top of the composite flange 4, the waterproof groove 122 is formed on the circumferential surface of the waterproof ring 121, the sealing arc rod 123 is fixedly installed on the top of the baffle plate 9, and the limiting frame 124 is fixedly installed on the rear side of the sealing arc rod 123. The limiting block 125 is set between the sealing arc rod 123 and the limiting frame 124. The limiting groove 126 is opened on the rear side of the composite flange 4. The elastic telescopic rod 127 is fixedly installed on the inner wall of the limiting groove 126. After the waterproof ring 121 deforms, it forms a full-fit seal with the gap, further sealing the connection gap between the insulator body 2 and the composite flange 4, preventing rainwater or dew from entering from the source, thereby ensuring the sealing and waterproof performance of the insulator body 2. The insulator body 2 and the composite flange 4 have a sealing rubber ring. The aforementioned waterproof ring 121 is used to cooperate with the sealing rubber ring, thereby further improving the sealing effect between the insulator body 2 and the composite flange 4.

[0029] The top of the free end of the elastic telescopic rod 127 is set as an inclined surface, the limit frame 124 contacts the composite flange 4, and the waterproof ring 121 is made of rubber. The rubber material of the waterproof ring 121 can seal the composite flange 4.

[0030] The sealing arc rod 123 contacts the composite flange 4. The sealing arc rod 123 is used to compress the waterproof ring 121. The elastic telescopic rod 127 is used to limit the sealing arc rod 123. With the limiting effect of the elastic telescopic rod 127, the sealing arc rod 123 can form a continuous and uniform pressure on the waterproof ring 121, which can offset the loosening of the sealing gap caused by thermal expansion and contraction, thereby achieving long-term sealing and further improving the waterproof performance of the insulator body 2.

[0031] The support assembly includes a speed control groove 131, a hollow frame 132, an adjusting plate 133, an arc ring 134, a support plate 135, and a support hole 136. The speed control groove 131 is located on the top of the base 1. The hollow frame 132 is fixedly installed on the inner wall of the speed control groove 131. The adjusting plate 133 is slidably installed on the inner wall of the hollow frame 132. The arc ring 134 is fixedly installed on the inner wall of the hollow frame 132. The support plate 135 is slidably installed on the inner wall of the hollow frame 132. The support hole 136 is located at the bottom of the insulator body 2. The adjusting plate 133 drives the sealing arc rod 123 to move slowly and uniformly, which can avoid the rigid rapid compression that causes excessive local stress on the waterproof ring 121, resulting in uneven deformation or even damage. This ensures that the waterproof ring 121 is uniformly circumferentially fitted to the insulator body 2 and the composite flange 4.

[0032] A spring is installed between the support plate 135 and the hollow frame 132. The spring can support the support plate 135. The adjusting plate 133 contacts the sealing arc rod 123 and the arc ring 134. When the support plate 135 moves to the left, it will contact the support hole 136 and provide auxiliary support for the insulator body 2. The auxiliary support can offset the stress caused by strong outdoor wind vibration, thereby reducing the loosening of the insulator body 2 caused by long-term uneven stress and extending the service life of the insulator body 2.

[0033] When the baffle plate 9 moves to the right, it will cause the sealing arc rod 123 to move to the right. When the sealing arc rod 123 moves to the right, it will come into contact with the waterproof ring 121 and squeeze the waterproof ring 121. The waterproof ring 121 will deform under the pressure of the sealing arc rod 123, and the deformation of the waterproof ring 121 will fill the gap between the insulator body 2 and the composite flange 4. At the same time, when the sealing arc rod 123 moves to the right, it will cause the limiting frame 124 to move to the right. When the limiting frame 124 moves to the right, it will come into contact with the inclined surface of the free end of the elastic telescopic rod 127 and squeeze the free end of the elastic telescopic rod 127. The free end of the elastic telescopic rod 127 moves downward and stores force under the pressure of the limiting frame 124. As the sealing arc rod 123 continues to move to the right, it will drive the limiting frame 124 to move to the right. The limiting frame 124 will disengage from the free end of the elastic telescopic rod 127. After the free end of the elastic telescopic rod 127 disengages from the limiting frame 124, the free end of the elastic telescopic rod 127 moves upward and resets under its own elastic force. The upward movement of the free end of the elastic telescopic rod 127 will limit the limiting frame 124. The limiting frame 124 is limited by the free end of the elastic telescopic rod 127, so that the sealing arc rod 123 is tightly attached to the circumferential surface of the waterproof ring 121.

[0034] When the sealing arc rod 123 moves to the right, it will contact the adjusting plate 133 and squeeze the adjusting plate 133. The adjusting plate 133 moves to the right under the pressure of the sealing arc rod 123. The adjusting plate 133 moves to the right and contacts the arc ring 134 and squeezes the arc ring 134. The arc ring 134 undergoes slow deformation under the pressure of the adjusting plate 133. The slow deformation of the arc ring 134 causes the adjusting plate 133 to move slowly to the right. The slow movement of the adjusting plate 133 to the right causes the sealing arc rod 123 to move slowly to the right. Simultaneously, the adjustment plate 133 moving to the right will compress the gas inside the hollow frame 132. The gas inside the hollow frame 132 moves downward due to the compression of the adjustment plate 133. The downward movement of the gas inside the hollow frame 132 will compress the support plate 135. The support plate 135 moves to the left due to the compression of the gas inside the hollow frame 132. The leftward movement of the support plate 135 will pull the spring 1. The spring 1 will deform and store force due to the pull of the support plate 135. At the same time, the leftward movement of the support plate 135 will contact the support hole 136 and provide auxiliary support for the insulator body 2.
