Description

Technical Field

[0001] The invention belongs to the technical field of insulators, and more specifically, particularly relates to a composite large-disk diameter outer umbrella-shaped glass insulator. Background Art

[0002] Insulators are a key component used in power systems. Their main function is to support and insulate power transmission lines and equipment to prevent current leakage or short circuits. They are usually made of glass and ceramic materials, which have good electrical properties and weather resistance and can work stably under various environmental conditions. Insulator strings refer to structures formed by connecting multiple insulators in series in a certain way. They are often used in power systems. The main function of insulator strings is to support and insulate power transmission lines to prevent current from passing through insulator strings to the bracket or the ground, thereby ensuring the safe operation of the power system. Insulator strings can also be used to adjust the voltage distribution of the power system and improve the efficiency of power transmission.

[0003] At present, the existing insulators (such as patent number: CN115458250A) disclose an explosion-proof glass insulator, including: an iron cap, a cavity with a U-shaped cross section is opened at the bottom, and a QR code area is arranged on the outer wall of the iron cap; a locking pin is located at the center of the iron cap, and the axis of the locking pin coincides with the axis of the U-shaped cavity of the iron cap, the pin rod of the locking pin penetrates into the U-shaped cavity of the iron cap from the upper part of the iron cap, and the pin head of the locking pin fits the upper part of the iron cap; a steel foot, the cone head part is located inside the U-shaped cavity of the iron cap; a glass part, the top of which is arranged between the inner wall of the U-shaped cavity of the iron cap and the cone head part of the steel foot, and the surface of the glass part is covered with an anti-pollution flash coating. The explosion-proof glass insulator can effectively prevent the glass fragments from falling from a high altitude to the ground after the tempered glass insulator breaks, causing damage to people or objects on the ground, and has good anti-pollution flash performance, and can realize product traceability.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] 1. When multiple insulators need to be installed into an insulator string, they need to be connected with bolts and nuts of specific sizes or types, and a torque wrench of corresponding size needs to be used to ensure that the bolts or nuts are properly tightened to ensure the stability and reliability of the connection. However, the use of specific tools for installation requires additional steps and operations, which increases the time cost of installation. When installing and adjusting multiple insulator strings, it will be more cumbersome.

[0006] 2. Insulators are usually placed outdoors, so the connecting parts between insulators will be exposed to the outdoor environment for a long time. The outdoor environment may have severe weather conditions such as high temperature, heavy rain, strong wind, etc. At this time, the connecting parts of the insulators may be affected by physical and climatic factors such as sun, rain, wind erosion, etc., causing corrosion and rust on the surface of the parts, thereby reducing the strength and durability of the insulator connection mechanism.

[0007] 3. Insulator strings are generally connected to high power towers or poles. High insulator strings are easily affected by wind, especially in severe weather conditions such as storms. Strong winds may cause vibrations in the insulator strings, which may cause stress concentration inside the insulators. At this time, the insulator strings may transfer the vibrations to the insulators, causing the insulators to be damaged by excessive vibrations.

[0008] Therefore, in view of this, the existing structure and defects are studied and improved, and a composite large-disk diameter outer umbrella-shaped glass insulator is provided, in order to achieve the purpose of having more practical value. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, by providing a ball head, the ball head on the insulator body is aligned with the cap socket at the lower end of the other insulator body. At this time, the ball head will squeeze the two connecting rings. Since the ball head is a flat-top cone, when the ball head enters the inside of the cap socket, the two connecting rings are squeezed and move toward the direction of the two connecting frames. At this time, the springs at both ends are squeezed. When the ball head completely enters the inside of the cap socket, the ball head no longer squeezes the two connecting rings. The two springs rebound, so that the two fixing blocks push the connecting rings back to their original positions. At this time, the two connecting rings are located at the lower end position of the ball head, so that the insulator at the upper end will move the lower end The insulators are stuck, so the staff only needs to press two insulators to achieve the purpose of connecting the insulators. When the insulator string needs to be disassembled, it is only necessary to push the paddles on both sides. The paddles will drive the corresponding fixed blocks to move. At this time, the two fixed blocks will drive the corresponding connecting rings to move. At this time, the distance between the two connecting rings will gradually increase. At this time, the staff will take out the ball head from between the two connecting rings, thereby achieving the purpose of directly disassembling the insulator string, avoiding the need for staff to use additional tools for installation, which increases the time cost of installation and simplifies the installation and disassembly steps.

[0022] In the present invention, a lifting plate is provided, and when the two insulators are connected, the two connecting rings are in a closed state. At this time, the two paddles are located at one end of the lifting plate facing the hat socket. At this time, the staff rotates the nut, and the nut drives the connecting column 1 and the driving sprocket to rotate. Since the driving sprocket and the driven sprocket are both engaged with the synchronous chain, the connecting column 1 and the connecting column 2 simultaneously drive the two threaded rods to rotate. Since the lifting plate does not rotate, the lifting plate will move vertically downward in parallel until the lower surface of the lifting plate is tightly against the upper surface of the corresponding connecting frame. At this time, the side of the paddle facing away from the hat socket will be tightly against the corresponding lifting plate, and the paddle will not move, thereby avoiding position displacement of the paddle when the insulators are connected, making the insulators more stable when connected.

[0023] In the present invention, by providing a cap socket, when two insulators are connected, the ball head and the connecting rod of one insulator will enter the cap socket of the other insulator. At this time, the cap socket will play a protective role, providing a function of isolating the ball head and the connecting rod from the external environment, thereby preventing the connecting parts of the insulators from being affected by physical and climatic factors such as sun, rain, wind erosion, etc., which may cause corrosion and rust on the surface of the parts, so that the strength and durability of the insulator connection mechanism are not affected.

[0024] In the present invention, by providing rubber pads, when two insulators are connected, the two rubber pads at the upper ends will wrap the connecting rod at the lower end. When the insulator string vibrates, the rubber pads will absorb part of the vibration, thereby avoiding the problem that the insulator string transmits excessive vibration to the insulator, causing the insulator to be damaged again, and improving the service life of the insulator.

[0025] In the present invention, due to the use of composite technology, the structure of the large disc diameter is more solid and can withstand a larger mechanical load, thereby improving the durability and reliability of the insulator. The umbrella-shaped design increases the surface area of ​​the insulator body, making its flashover distance longer, thereby improving the insulator's resistance to electrical breakdown and reducing the failure rate caused by electrical breakdown.

[0026] In the present invention, a limit column is provided. When the staff pulls the paddle, the paddle drives the fixed block to squeeze the spring. Since the limit column is fixedly connected to the long rod, the limit column does not move with the movement of the fixed block. When the paddle drives the fixed block to move to a certain distance, the limit column will resist the inner wall of the corresponding fixed block, so that the fixed block cannot continue to move toward the inside of the connecting frame, thereby avoiding excessive squeezing of the spring by the two fixed blocks, causing fatigue of the spring metal material and reducing its strength and toughness, thereby reducing the risk of spring breakage.

The composite large-disk diameter outer umbrella-shaped glass insulator is also provided with a quick connection structure, including a connecting rod 2, a ball head 3, a cap socket 4, two connecting frames 5 and two connecting rings 13. The upper surface of the insulator body 1 is fixedly connected to the lower surface of the connecting rod 2, the upper surface of the connecting rod 2 is fixedly connected to the lower surface of the ball head 3, the upper surface of the insulator body 1 is fixedly connected to the upper surface of the cap socket 4, the two connecting frames 5 are fixedly connected to the two ends of the cap socket 4, and the two connecting frames 5 are provided with a side facing the cap socket 4. The two connection frames 5 are both movably connected with the fixing block 14 through the groove 16. The lower surface of the cap socket 4 is provided with a hole 21. The two connection rings 13 are both located in the hole 21. The two sides of the cap socket 4 are provided with rectangular grooves 15 corresponding to the positions of the fixing blocks 14. The two fixing blocks 14 are fixedly connected to the corresponding connection rings 13 through the rectangular grooves 15. The opposite sides of the two connection rings 13 are fixedly connected with rubber pads 31. The ball head 3 on the insulator body 1 is aligned with the cap socket 4 at the lower end of the other insulator body 1. At this time, the ball head 3 will squeeze the two The connecting ring 13, since the ball head 3 is a flat-topped cone, when the ball head 3 enters the inside of the hat socket 4, the two connecting rings 13 are squeezed and move toward the direction of the two connecting frames 5. At this time, the springs 20 at both ends are squeezed. When the ball head 3 completely enters the inside of the hat socket 4, the ball head 3 no longer squeezes the two connecting rings 13, and the two springs 20 rebound, so that the two fixing blocks 14 push the connecting rings 13 back to their original positions. At this time, the two connecting rings 13 are located at the lower end of the ball head 3, so that the insulator at the upper end clamps the insulator at the lower end, so the staff only needs to press the two The insulator can achieve the purpose of connecting the insulators. When the insulator string needs to be disassembled, it is only necessary to push the paddles 12 on both sides. The paddles 12 will drive the corresponding fixed blocks 14 to move. At this time, the two fixed blocks 14 will drive the corresponding connecting rings 13 to move. At this time, the distance between the two connecting rings 13 will gradually increase. At this time, the staff will take out the ball head 3 from between the two connecting rings 13, thereby achieving the purpose of directly disassembling the insulator string, avoiding the need for the staff to use additional tools for installation, which increases the time cost of installation and simplifies the installation and disassembly steps.

[0039] The two fixing blocks 14 are fixedly connected to a connecting plate 18 on one side facing away from the hat socket 4, and springs 20 are arranged inside the two connecting frames 5. The two springs 20 are located at one end of the two fixing blocks 14 facing away from the springs 20, and the two springs 20 are fixedly connected to the corresponding connecting plate 18. The ends of the two springs 20 facing away from the hat socket 4 are fixedly connected to a connecting plate 2 19, and the two connecting plates 2 19 are fixedly connected to the corresponding connecting frames 5 on one side facing away from the springs 20. When the two insulators are connected, the two connecting rings 13 are in a closed state. At this time, the two paddles 12 are located at one end of the lifting plate 7 facing the hat socket 4, and the staff rotates the nut 9 at this time. , the nut 9 drives the connecting column 1 28 and the driving sprocket 27 to rotate. Since the driving sprocket 27 and the driven sprocket 25 are both engaged with the synchronous chain 10, the connecting column 1 28 and the connecting column 2 30 simultaneously drive the two threaded rods 11 to rotate. Since the lifting plate 7 does not rotate, the lifting plate 7 will move vertically downward in parallel until the lower surface of the lifting plate 7 is tightly against the upper surface of the corresponding connecting frame 5. At this time, the side of the paddle 12 away from the cap socket 4 will be tightly against the corresponding lifting plate 7, and the paddle 12 will not move, thereby avoiding the position displacement of the paddle 12 when the insulator is connected, making the insulator more stable when connected.

[0040] The upper surfaces of the two connecting frames 5 are penetrated with long grooves 8, and the upper ends of the two connecting frames 5 are provided with paddles 12. The lower surfaces of the two paddles 12 pass through the long grooves 8 and are fixedly connected to the corresponding fixed blocks 14. Two grooves 22 are provided inside the two fixed blocks 14. The two fixed blocks 14 are movably sleeved with limit posts 23 through the grooves 22. Two holes 24 corresponding to the positions of the limit posts 23 are penetrated on the side of each fixed block 14 away from the cap socket 4. When the two insulators are connected, the ball head 3 and the connecting rod 2 of one insulator will enter the cap socket 4 of the other insulator. At this time, the cap socket 4 will play a protective role, providing the ball head 3 and the connecting rod 2 with an isolation effect from the external environment, thereby preventing the connecting parts of the insulators from being affected by physical and climatic factors such as sun, rain, and wind erosion, which may cause corrosion and rust on the surface of the parts, so that the strength and durability of the insulator connection mechanism are not affected.

[0041] The inner walls of the two connecting frames 5 are fixedly connected with two long rods 17 corresponding to the positions of the second holes 24. The end of each long rod 17 facing the hat socket 4 passes through the second hole 24 and is fixedly connected to the corresponding limit column 23. The upper surfaces of the two connecting frames 5 are fixedly connected with U-shaped plates 6. The lower ends of the two U-shaped plates 6 are rotatably connected with threaded rods 11. The lower surfaces of the two threaded rods 11 are rotatably connected to the upper surfaces of the corresponding connecting frames 5. When the two insulators are connected, the two rubber pads 31 at the upper ends will wrap the connecting rods 2 at the lower ends. When the insulator string vibrates, the rubber pads 31 will absorb part of the vibration, thereby avoiding the problem that the insulator string will transmit too much vibration to the insulator, causing the insulator to be damaged again, thereby improving the service life of the insulator.

[0042] The lower surface of each U-shaped plate 6 is penetrated by two holes three 26 corresponding to the position of the threaded rod 11, and the two U-shaped plates 6 are rotatably connected to the connecting column one 28 through the hole three 26 at the rear end position, and the two U-shaped plates 6 are rotatably connected to the connecting column two 30 through the hole three 26 at the front end position. The two connecting columns one 28 are fixedly connected to the driving sprocket 27, and the two connecting columns two 30 are fixedly connected to the driven sprocket 25. The upper surfaces of the two connecting columns one 28 are fixedly connected to the nuts 9. The large-diameter structure is more solid and can withstand greater mechanical loads, thereby improving the durability and reliability of the insulator. The umbrella-shaped design increases the surface area of ​​the insulator body 1, making its flashover distance longer, improving the insulator's resistance to electrical breakdown, and reducing the failure rate caused by electrical breakdown.

[0043] The upper ends of the two U-shaped plates 6 are both provided with synchronous chains 10, the rear ends of the two synchronous chains 10 are meshed and connected with the corresponding driving sprockets 27, the front ends of the two synchronous chains 10 are meshed and connected with the corresponding driven sprockets 25, and the lower ends of the two U-shaped plates 6 are both provided with lifting plates 7, and the upper surface of each lifting plate 7 is penetrated with two thread grooves 29 corresponding to the positions of the threaded rods 11, and the two lifting plates 7 are threadedly sleeved with the corresponding threaded rods 11 through the thread grooves 29. When the staff member pulls the paddle 12, the paddle is The plate 12 drives the fixed block 14 to squeeze the spring 20. Since the limit column 23 is fixedly connected to the long rod 17, the limit column 23 does not move with the movement of the fixed block 14. When the paddle 12 drives the fixed block 14 to move to a certain distance, the limit column 23 will press against the inner wall of the corresponding fixed block 14, so that the fixed block 14 cannot continue to move toward the inside of the connecting frame 5, thereby avoiding excessive squeezing of the spring 20 by the two fixed blocks 14, causing fatigue of the metal material of the spring 20 and reducing its strength and toughness, thereby reducing the risk of breakage of the spring 20.

[0044] Working principle:

[0045] The first step is to align the ball head 3 on the insulator body 1 with the cap socket 4 at the lower end of the other insulator body 1. At this time, the ball head 3 will squeeze the two connecting rings 13. Since the ball head 3 is a flat-topped cone, when the ball head 3 enters the cap socket 4, the two connecting rings 13 are squeezed and move toward the direction of the two connecting frames 5. At this time, the springs 20 at both ends are squeezed. When the ball head 3 completely enters the cap socket 4, the ball head 3 no longer squeezes the two connecting rings 13. The two springs 20 rebound, so that the two fixing blocks 14 push the connecting rings 13 back to their original positions. At this time, the two connecting rings 13 are located at the lower end position of the ball head 3, so that the insulator at the upper end clamps the insulator at the lower end. Therefore, the staff only needs to press the two insulators to achieve the purpose of connecting the insulators. When the insulator string needs to be disassembled, it is only necessary to pull the paddles 12 on both sides. The paddles 12 will drive the corresponding fixing blocks 14 to move. At this time, the two fixing blocks 14 will drive the corresponding connecting rings 13 to move. At this time, the spacing between the two connecting rings 13 will gradually increase. At this time, the staff The staff takes out the ball head 3 from between the two connecting rings 13, so as to achieve the purpose of directly disassembling the insulator string, avoid the staff needing to use additional tools for installation, thereby increasing the time cost of installation, and simplifying the steps of installation and disassembly. When the two insulators are connected, the two connecting rings 13 are in a closed state. At this time, the two paddles 12 are located at the end of the lifting plate 7 facing the hat socket 4. At this time, the staff rotates the nut 9, and the nut 9 drives the connecting column 1 28 and the driving sprocket 27 to rotate. Since the driving sprocket 27 and the driven sprocket 25 are both engaged with the synchronous chain 10, at this time, the connecting column 1 28 and the connecting column 2 30 simultaneously drive the two threaded rods 11 to rotate. Since the lifting plate 7 does not rotate, the lifting plate 7 will move vertically downward in parallel until the lower surface of the lifting plate 7 is tightly against the upper surface of the corresponding connecting frame 5. At this time, the side of the paddle 12 facing away from the hat socket 4 will be tightly against the corresponding lifting plate 7, and the paddle 12 will not move, so as to avoid the position displacement of the paddle 12 when the insulator is connected, so that the insulator becomes more stable when connected.

[0046] In the second step, when the two insulators are connected, the ball head 3 and the connecting rod 2 of one insulator will enter the cap socket 4 of the other insulator. At this time, the cap socket 4 will play a protective role, providing a function of isolating the ball head 3 and the connecting rod 2 from the external environment, thereby preventing the connecting parts of the insulators from being affected by physical and climatic factors such as sun, rain, wind erosion, etc., which may cause corrosion and rust on the surface of the parts, so that the strength and durability of the insulator connection mechanism are not affected. When the two insulators are connected, the two rubber pads 31 at the upper end will wrap the connecting rod 2 at the lower end. When the insulator string vibrates, the rubber pads 31 will absorb part of the vibration, thereby avoiding the problem that the insulator string will transmit too much vibration to the insulator, causing the insulator to be damaged again, thereby improving the service life of the insulator.

[0047] The third step is that the structure with a large disc diameter is more solid and can withstand greater mechanical loads, which improves the durability and reliability of the insulator. The umbrella-shaped design increases the surface area of ​​the insulator body 1, making its flashover distance longer, improving the insulator's resistance to electrical breakdown, and reducing the failure rate caused by electrical breakdown. When the staff turns the paddle 12, the paddle 12 drives the fixed block 14 to squeeze the spring 20. Since the limit column 23 is fixedly connected to the long rod 17, the limit column 23 does not move with the movement of the fixed block 14. When the paddle 12 drives the fixed block 14 to move to a certain distance, the limit column 23 will resist the inner wall of the corresponding fixed block 14, so that the fixed block 14 cannot continue to move toward the inside of the connecting frame 5, avoiding the two fixed blocks 14 from excessively squeezing the spring 20, causing fatigue of the metal material of the spring 20, reducing its strength and toughness, and reducing the risk of the spring 20 breaking.
