Description

Technical Field

[0001] The present invention relates to the technical field of insulators, and more particularly to an insulator connection structure which is easy to clean. Background Art

[0002] An insulator is a device used to support and fix power line conductors or cables, and to provide insulation protection between the conductors and brackets or other metal structures. Insulators are usually made of insulating materials such as ceramics, glass fiber reinforced plastics, etc., to prevent current from flowing between the conductors and the supporting structure, thereby ensuring the safe and stable operation of the power transmission system. In transmission lines or distribution systems, the role of insulators is similar to an electrical insulation isolator, preventing current from flowing to the ground through the insulator bracket, thereby ensuring the normal operation of the power system.

[0003] The Chinese patent publication number CN112309654A discloses an insulator with a self-cleaning effect for an overhead transmission line. By setting a power part and a hemispherical wind cup arranged on the power part, the hemispherical wind cup is affected by airflow, and the wind pressure generated by the airflow generates a certain torque to rotate the hemispherical wind cup, and then the rotating hemispherical wind cup drives the fixed ring to rotate along the bearing, providing sufficient power for the rotation of the fixed ring. By setting a cleaning part and a cleaning brush that is tightly fitted with the upper surface of the umbrella skirt arranged on the cleaning part, the cleaning brush cleans the upper surface of the umbrella skirt as the fixed ring rotates, thereby realizing self-cleaning of the insulator during use. By setting a detachable power part and a cleaning brush, it is convenient to disassemble the power part and the cleaning brush, which facilitates the later maintenance and overhaul of the power part and the cleaning brush, and solves the problem that the cleaning brush of the traditional self-cleaning insulator is not easy to disassemble.

[0004] When insulators are used, they need to be strung together in multiples. However, due to the high height of the high-voltage line and the heavy weight of the insulators, the insulators need to be connected and assembled one by one in the air when they are installed. Traditional insulators use R-type pins for connection. When connecting, due to the large friction between the R-type pins and the steel caps of the insulators, it is necessary to use tools such as hammers to hammer the R-type pins into the steel caps. However, using this method of connection at high altitudes not only causes inconvenience in construction, but also easily causes damage to the insulators during installation.

[0005] Since insulators are made of fragile materials such as ceramics or glass, they are easily damaged during long-term use and need to be replaced. However, insulators are connected in strings. When one of them needs to be replaced, the traditional method is to use a tensioner to pull the cable before replacing it. However, high-voltage cables are not only heavy, but also high. Using a tensioner to pull the cable before replacing the insulator will still cause inconvenience in replacement.

[0006] Therefore, it is necessary to provide an insulator connection structure that is easy to clean to solve the above problems. Summary of the invention

During the connection, due to the large friction between the pin and the steel cap of the insulator, it is necessary to use a hammer or other tools to hammer the pin into the steel cap. However, using this connection method at high altitude not only causes inconvenience in construction, but also easily causes damage to the insulator during installation.

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] Based on this, the R-type pin connection used in traditional insulators in the relevant technology can be improved. When connecting, due to the large friction between the R-type pin and the steel cap of the insulator, it is necessary to use a hammer or other tools to hammer the R-type pin into the steel cap. However, using this connection method at high altitude not only causes inconvenience in construction, but also easily causes damage to the insulator during installation.

[0051] See also Figure 1-Figure 14, an insulator connection structure that is easy to clean, comprising: a plurality of insulators 1 and two tightening components 5, a steel cap 2 is fixedly connected to the top of the insulator 1, a mounting component 3 is arranged at the bottom of the insulator 1, and a cleaning component 4 is arranged at the outer end of the insulator 1, a hydrophobic coating is arranged on the outer surface of the insulator 1, a connecting component 6 is arranged at the outer end of the tightening component 5, and the two tightening components 5 are connected to each other head to tail through the connecting component 6, the mounting component 3 comprises a rotating block 310 and two symmetrically distributed pins 38, a plurality of driving blocks 1 312 equidistantly distributed in an annular shape are fixedly connected to the outer surrounding of the rotating block 310, and a plurality of driving blocks 2 313 are fixedly connected to the outer surrounding of the rotating block 310, a plurality of abutting grooves 1 314 are arranged between the plurality of driving blocks 1 312, and a plurality of abutting grooves 2 315 are arranged between the plurality of driving blocks 2 313, wherein: the pin 38 abuts against the inclined surfaces of the driving block 1 312 and the driving block 2 313 respectively by moving up and down, and drives the rotating block 310 to rotate.

[0052] The device in this scheme is mainly used for hanging insulators in high-voltage transmission lines, equipment to support and fix power line conductors or cables, and a device to provide insulation protection between conductors and brackets or other metal structures. Multiple insulators 1 can be connected together through steel caps 2 and mounting components 3, and multiple insulators 1 are strung together for use. The outer surface of the insulator 1 is arranged in an umbrella-like arc shape, which is mainly to prevent rainwater from accumulating on the surface of the insulator 1 and conducting electricity. The arc-shaped arrangement can make rainwater fall in drops, and the bottom is arranged in a circle structure, which can increase the creepage distance, thereby increasing the resistance of the insulator and reducing the risk of leakage.

[0053] An installation component 3 is arranged at the bottom of the insulator 1, and a steel cap 2 is arranged at the top thereof. The installation component 3 can be inserted into the steel cap 2, so that multiple insulators 1 can be connected end to end. A cleaning component 4 is also arranged at the outer end of the insulator 1. The cleaning component 4 is mainly used to assist the staff to clean the insulator 1.

[0054] The mounting assembly 3 is fixed at the bottom of the insulator 1 near the center and is coaxially arranged with the steel cap 2. The steel cap 2 is connected to the mounting assembly 3 through the through hole 10 and the limit groove 9 opened at the top. After the limit block 34 is inserted into the limit groove 9 through the through hole 10, the latch 38 is pulled to move the latch 38 downward to the abutment groove 1 314. After releasing the hand, the latch 38 is reset by the force of the telescopic spring 37. The latch 38 will abut against the inclined surface of the driving block 2 313, and then the rotating block 310 is driven to drive the limit block 34 to rotate in the limit groove 9, so that the limit block 34 and the through hole 10 are misaligned, thereby achieving the purpose of connecting the two insulators 1. , so that it can quickly complete the installation and connection without using other auxiliary tools after high-altitude operations. Traditional insulators use R-type pins for connection. When connecting, due to the large friction between the R-type pins and the steel caps of the insulators, it is necessary to use tools such as hammers to smash the R-type pins into the steel caps. However, using this method for connection during high-altitude operations not only causes inconvenience in construction, but also easily causes damage to the insulators during installation. Compared with the traditional connection method using R-type pins, this solution only needs to pull the pin 38 downward once to complete the installation and connection, which can improve the convenience of installation, reduce the difficulty of installation, and reduce the installation burden of the staff.

[0055] The tightening assembly 5 is used to replace the damaged insulator 1 at a later stage. A slot 7 is provided on each steel cap 2. The slot 7 is mainly used to cooperate with the tightening assembly 5. After the two cross bars 51 are respectively passed through the slots 7 on the two steel caps 2, and then the two sets of ball heads 65 and the hoop shell 62 are clamped together, the two tightening assemblies 5 can be connected together at the head and tail to form a rectangle. By rotating the threaded sleeve 53, the two insulators 1 can be pulled closer. At this time, the insulator 1 in the middle will be loosened. The two insulators 1 can be temporarily connected together by the tightening assembly 5, which can be conveniently The staff replaces the middle insulator 1 to improve the convenience of replacement. Traditionally, a tensioner is used to pull the cable before replacement. However, the high-voltage line is relatively high. The tensioner needs to clamp the cable first, and then find a support point to fix the tensioner before use. This will cause the construction workers to move repeatedly at high altitudes, causing inconvenience in replacement. This solution can complete the fixation through the cooperation of the tightening component 5 and the steel cap 2. The staff does not need to move over a large range, which can improve the stability when working at heights. At the same time, the volume and weight of the tightening component 5 are smaller than the tensioner, making it more convenient to carry.

[0056] Optionally, in some embodiments, see Figure 1-Figure 7 as well as Fig. 9The mounting assembly 3 also includes a steel foot 31, which is connected to the inside of the insulator 1 through cement 11, and a fixed cylinder 32 is fixedly connected to the bottom end of the steel foot 31. A rotating block 310 is located inside the fixed cylinder 32, and two slip rings 316 are fixedly connected to the outer end of the rotating block 310. The rotating block 310 is rotatably connected to the inner wall of the fixed cylinder 32 through the slip ring 316. The driving block 1 312 and the driving block 2 313 are both arranged in an arc shape and are both fitted on the outer periphery of the rotating block 310. The cross-sections of the driving block 1 312 and the driving block 2 313 are both arranged in a right-angled triangle.

[0057] The outer end of the fixed cylinder 32 is fixedly connected to two symmetrically distributed plug rods 33, the outer end of the steel cap 2 is fixedly connected to two plug blocks 8, the plug blocks 8 are adapted to the plug rods 33, the outer end of the fixed cylinder 32 is fixedly connected to two shells 36, and telescopic springs 37 are arranged inside the two shells 36. Movable grooves 39 are opened on both sides of the fixed cylinder 32, and the shells 36 are connected with the interior of the fixed cylinder 32 through the movable grooves 39. The pin 38 passes through the movable grooves 39 and the shells 36 in sequence, and the pin 38 extends to the outside, and the outer end of the pin 38 is connected to a pull ring 35.

[0058] The outer end of the latch 38 is fixedly connected with a connecting block 311, which is located inside the shell 36, and the outer end of the connecting block 311 is fixedly connected to the top of the telescopic spring 37. The connecting block 311 drives the latch 38 to move downward through the force of the telescopic spring 37 and then resets. The bottom end of the rotating block 310 is fixedly connected to the limiting block 34. A through hole 10 adapted to the limiting block 34 is opened at the top of the steel cap 2, and a limiting groove 9 is arranged inside the steel cap 2. The limiting groove 9 and the through hole 10 are connected, and the limiting block 34 passes through the through hole 10 and extends to the inside of the limiting groove 9.

[0059] The steel foot 31 in this solution is mainly fixed to the inside of the insulator 1 by cement 11. In order to ensure the strength of the connection, the mounting assembly 3 and the steel cap 2 are both made of metal. Therefore, cement 11 is used for connection, mainly to insulate and isolate the mounting assembly 3 and the steel cap 2. A fixing cylinder 32 is fixed at the bottom of the steel foot 31. The interior of the fixing cylinder 32 is hollow. A rotating block 310 is arranged inside the fixing cylinder 32. A limit block 34 is fixedly connected to the bottom of the rotating block 310. The limit block 34 penetrates the fixed steel foot 311. The fixed cylinder 32 extends to the outside, and movable grooves 39 are provided on both sides of the fixed cylinder 32. At the same time, a shell 36 is fixed at the outer end of the movable groove 39. The shell 36 is connected to the inside of the fixed cylinder 32 through the movable groove 39. A telescopic spring 37 is fixed inside the shell 36. At the same time, a latch 38 passes through the shell 36 and the movable groove 39 in sequence and extends to the inside of the fixed cylinder 32. A connecting block 311 is fixed at the outer end of the latch 38. The connecting block 311 is fixedly connected to the top of the telescopic spring 37. The two latches 38 are connected at the same time. The two latches 38 are also connected to the two ends of the pull ring 35. By pulling the pull ring 35, the two latches 38 can be driven to move at the same time. The upper and lower ends of the rotating block 310 inside the fixed cylinder 32 are fixed with slip rings 316. The rotating block 310 is rotatably connected to the inner wall of the fixed cylinder 32 through the slip ring 316. The outer enclosure of the rotating block 310 is fixed with a driving block 1 312 and a driving block 2 313. The driving block 1 312 is located below the driving block 2 313. The driving block 1 312 and the driving block 2 313 are both set to four. The four driving blocks 1 312 are connected to each other to form a circular shape, the peak and valley formed between every two driving blocks 1 312 is abutment groove 1 314, the four driving blocks 2 313 are arranged in the same manner as the driving block 1 312, and the peak and valley formed between every two driving blocks 2 313 is abutment groove 2 315, the shape and size of driving block 1 312 and driving block 2 313 are consistent, but the peaks of driving block 1 312 and driving block 2 313 are staggered, and the cross-sections of driving block 1 312 and driving block 2 313 are arranged in right-angled triangles.

[0060] When making a connection, it is first necessary to insert the limit block 34 into the through hole 10 on the steel cap 2 so that the limit block 34 is located inside the limit groove 9. Since the shape of the through hole 10 is the same as that of the limit block 34, which is similar to an elliptical setting, when the limit block 34 rotates, the limit block 34 can be misaligned with the through hole 10, so that the limit block 34 cannot be pulled out. Pull the pull ring 35 downward, the pull ring 35 will drive the two latches 38 to move downward, and at the same time, the latches 38 will also compress the telescopic spring 37 through the connecting block 311. The latch 38 moving downward will first move downward from the abutment groove 2 315 to the inclined surface of the driving block 1 312. The latch 38 is restricted by the movable groove 39 and the shell 36 so that it can only move up and down. After abutting with the inclined surface of the driving block 1 312, it will drive the driving block 1 312 to drive the rotating block 310 to rotate. When the rotating block 310 rotates so that the latch 38 is located in the abutment groove 1 314, release the pull ring 35, and you can The latch 38 is reset by the force of the telescopic spring 37, and the latch 38 moving upward will abut against the inclined surface of the driving block 2 313, and the rotating block 310 is rotated again by the same principle. At this time, the position of the latch 38 is moved from the original abutment groove 2 315 to another adjacent abutment groove 2 315. Since the driving block 1 312 and the driving block 2 313 are set to four, the rotation angle of the rotating block 310 and the limit block 34 is ninety degrees at this time, which just causes the limit block 34 and the through hole 10 to be misaligned, and the limit block 34 is stuck in the limit groove 9 to complete the connection.

[0061] Two plug rods 33 are fixed on both sides of the outer end of the fixed tube 32, and two plug-in blocks 8 are fixed on both sides of the outer end of the steel cap 2. The two plug rods 33 are mainly used to cooperate with the plug-in blocks 8, so that after the plug rods 33 are inserted into the plug-in blocks 8, the installation component 3 and the steel cap 2 are restricted to prevent the installation component 3 and the steel cap 2 from rotating. Therefore, when inserting the limit block 34 into the through hole 10, it is necessary to first align the plug rod 33 with the plug-in block 8 and then insert it to keep the installation component 3 and the steel cap 2 relatively stable.

[0062] Optionally, in some embodiments, see Figure 2 and Figure 8 The cleaning component 4 includes an abutment strip 42 and a pressure strip 41. The abutment strip 42 is adapted to the outer end of the top of the insulator 1, and the pressure strip 41 is adapted to the outer end of the bottom of the insulator 1. The pressure strip 41 and the abutment strip 42 are fixedly connected. Cleaning strips 43 are fixedly connected to the inner sides of the pressure strip 41 and the abutment strip 42. The cleaning strip 43 abuts against the outer surface of the insulator 1, and the cleaning strip 43 is made of sponge material. The outer end of the abutment strip 42 is fixedly connected to a driving plate 44.

[0063] The cleaning component 4 in the present scheme is arranged at the outer end of the insulator 1, and the cleaning component 4 can be rotated at the outer end of the insulator 1. The pressure strip 41 and the abutment strip 42 are fixedly connected together. The pressure strip 41 is arranged in an arc shape so that it can fit on the outer surface of the insulator 1, and the pressure strip 41 is arranged in an irregular wave shape so that it can fit on the circle structure at the bottom of the insulator 1. Cleaning strips 43 are arranged on the inner sides of the pressure strip 41 and the abutment strip 42. The cleaning strip 43 is made of sponge so that it can fit tightly on the outer surface of the insulator 1. A driving plate 44 is fixed at the outer end of the abutment strip 42.

[0064] When the insulator 1 is in use, dust and dirt in the environment are easy to adhere to the surface, which will reduce the insulation of the insulator 1. Therefore, the staff needs to clean the insulator 1 frequently, and the cleaning method is usually to use a high-pressure water gun to directly spray on the surface of the insulator 1. At this time, the driving plate 44 is flushed by the high-pressure water gun, which will drive the pressure strip 41 and the abutment strip 42 to slide in a circle around the surface of the insulator 1, and the cleaning strip 43 will rub against the surface of the insulator 1, thereby achieving the purpose of auxiliary cleaning of the insulator 1. At the same time, the staff can also manually rotate the cleaning component 4 to assist the staff in cleaning the irregularities at the bottom of the insulator 1.

[0065] It is worth mentioning that a hydrophobic coating is provided on the surface of the insulator 1, and water droplets are difficult to adhere to the surface, forming water droplets that roll down, thereby reducing the accumulation of dirt. The super-hydrophobic surface makes it difficult for dirt to adhere. Even if there is a small amount of dirt, it will be automatically removed by natural forces such as wind and rain. At the same time, it has good corrosion resistance and can maintain its hydrophobic properties in harsh environments, which can effectively reduce the occurrence of pollution accidents and improve the safety and reliability of the power system.
