Description

Technical Field

[0001] This invention relates to the field of power insulator technology, specifically to a power insulator that is easy to calibrate. Background Technology

[0002] Electrical insulators are important insulating devices used in power systems. They are usually made of insulating materials and are mainly used to support and fix live conductors, and to maintain insulation between live conductors and ground, as well as between live conductors of different phases. They can ensure the safety and stability of power transmission in various harsh environments and prevent faults such as current leakage and electrical short circuits. Common types include porcelain insulators, glass insulators, and composite insulators. They are widely used in transmission lines, substations, electrified railways, and other fields, and are one of the key components to ensure the reliable operation of power systems.

[0003] Patent application CN222338002U discloses a power insulator calibration device, comprising an insulating shell, a fixed base fixedly connected to the inner wall of the insulating shell, an insulator body disposed on the outer wall of the top of the insulating shell, a central rotator fixedly connected to the bottom of the insulator body, a connecting rod fixedly connected to the outer wall of the central rotator, and a fixing device disposed on the inner wall of the insulating shell, the fixing device comprising a threaded rod, the threaded rod passing through the insulating shell and rotatably connected to the inner wall of the insulating shell, and a connecting seat fixedly connected to the outer wall of the threaded rod. This power insulator calibration device;

[0004] The aforementioned patent describes a process where rotating the insulating handle causes the threaded rod to engage the snap-fit ​​connector into the snap-fit ​​groove, thus securing the insulator body. However, during use, wind can cause the power insulator to sway, potentially leading to it falling off. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a conveniently calibrated power insulator to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power insulator that is easy to calibrate, comprising a power insulator, a base fixedly connected to the outer wall of the power insulator, and a calibration mechanism fixedly connected to the top of the power insulator;

[0007] The calibration facility includes:

[0008] A threaded block, which is rotatably connected to the top of an electrical insulator;

[0009] The bolt is threaded onto the inner wall of the threaded block. The descent of the power insulator causes the elasticity of the spring to reset the threaded block. This design makes the disassembly process simple and convenient.

[0010] Preferably, a bearing is rotatably connected between the threaded block and the top of the power insulator. When the power insulator is placed in the required position, if the position presses against the lever, it will drive the threaded block to rotate around the bearing, causing the two threaded blocks to move closer to the center position, thereby achieving convenient and quick calibration, greatly improving the calibration efficiency during the installation process, and reducing calibration time and labor costs.

[0011] Preferably, a lever is fixedly connected to the outer wall of the threaded block, and a bracket is fixedly connected to the outer wall of the base. After the two threaded blocks are brought close together, the bolts are rotated to bring the two bolts closer together, which can initially fix the required installation position. Then, the telescopic machine is powered on and started, which drives the telescopic rod to extend and retract. By pulling down the pressure rod to lower and squeeze the bending chamber, the connecting pipe and the air bladder are lowered. When the air bladder is squeezed to the required installation position, it can increase the fixation of the power insulator. At the same time, the pressure rod squeezes the bending chamber, which allows the gas in it to enter the air bladder through the connecting pipe, causing the air bladder to inflate and fit against the outer wall of the bolt and the required fixing position, further strengthening the fixing effect and effectively preventing the power insulator from shaking or even falling off due to wind or other factors.

[0012] Preferably, a spring is fixedly connected to the top of the bracket, and the outer wall of the spring is fixedly connected to the outer wall of the threaded block. When the threaded block is disassembled, the descent of the power insulator will cause the elasticity of the spring to drive the threaded block to reset. This design makes the disassembly process simple and convenient, reduces the difficulty of maintaining and replacing power insulators, and improves work efficiency.

[0013] Preferably, the number of the threaded block, bearing, spring, lever, and bolt are all two, and the two sets are arranged opposite each other. When the required position is pressed onto the lever, it will drive the threaded block to rotate. The threaded block rotates around the bearing as the center, thereby bringing the two threaded blocks closer to the middle position, which facilitates calibration. When the threaded block is removed, the descent of the power insulator will cause the elasticity of the spring to drive the threaded block to reset, which facilitates disassembly.

[0014] Preferably, the outer wall of the base is fixedly connected to a limiting mechanism. The synergistic effect of the calibration mechanism and the limiting mechanism not only realizes calibration and fixation during installation, but also enhances the stability of the power insulator in the overall structure. It effectively resists shaking caused by wind from multiple aspects, reduces the risk of the power insulator falling off, and ensures the safety and stability of power transmission.

[0015] Preferably, the limiting mechanism includes a bend chamber, the bottom of which is fixedly connected to the outer wall of the base, and the top of which is fixedly connected to a connecting pipe. An air bladder is fixedly connected to the top of the connecting pipe. When the bolt approaches, the telescopic mechanism is powered on and starts, causing the telescopic rod to extend and retract. As the telescopic mechanism pulls the lowering rod down via the telescopic rod, it compresses the bend chamber, causing the connecting pipe and air bladder to descend. The descent of the air bladder compresses the required installation position, thus increasing the fixation of the power insulator. Furthermore, when the lowering rod compresses the bend chamber, the gas in the bend chamber enters the air bladder through the connecting pipe, causing the air bladder to inflate. When inflated, the air bladder adheres to the outer wall of the bolt and the required fixing position, thus fixing them.

[0016] Preferably, a telescopic mechanism is fixedly connected to the outer wall of the base, a telescopic rod is movably connected to the top of the telescopic mechanism, a pressure rod is movably connected to the top of the telescopic rod, and the outer wall of the pressure rod is fixedly connected to the top of the bending chamber.

[0017] This invention provides a conveniently calibrated electrical insulator. It offers the following advantages:

[0018] 1. This conveniently calibrated power insulator, when placed in the desired position, if the position presses against the lever, will cause the threaded blocks to rotate around the bearing, bringing the two threaded blocks closer to the center position, thus achieving convenient and quick calibration, greatly improving calibration efficiency during installation, and reducing calibration time and labor costs.

[0019] 2. This easily calibrated power insulator allows for initial fixation at the desired installation position by rotating the bolts after bringing the two threaded blocks close together. Then, the telescopic mechanism is powered on and activated, causing the telescopic rod to extend and retract. Pulling down the pressure rod lowers and compresses the bending chamber, causing the connecting pipe and air bladder to descend. When the air bladder reaches the desired installation position, it increases the fixation of the power insulator. Simultaneously, the pressure rod compresses the bending chamber, allowing gas to enter the air bladder through the connecting pipe, causing the air bladder to inflate and adhere to the outer wall of the bolts and the desired fixing position, further strengthening the fixation and effectively preventing the power insulator from shaking or even falling due to wind or other factors.

[0020] 3. This easy-to-calibrate power insulator features a spring that resets the threaded block as it descends during disassembly. This design simplifies the disassembly process, reduces the difficulty of maintaining and replacing power insulators, and improves work efficiency.

[0021] 4. This easily calibrated power insulator, through the coordinated action of the calibration mechanism and the limiting mechanism, not only achieves calibration and fixation during installation, but also enhances the stability of the power insulator in its overall structure. It effectively resists shaking caused by wind from multiple aspects, reduces the risk of the power insulator falling off, and ensures the safety and stability of power transmission.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0033] Example 1, please refer to Figure 1-5 The present invention provides a technical solution: a power insulator that is easy to calibrate, comprising a power insulator 1, a base 2 fixedly connected to the outer wall of the power insulator 1, and a calibration mechanism 3 fixedly connected to the top of the power insulator 1;

[0034] The electrical insulator 1 is locked in the desired position via its top position.

[0035] Calibration facility 3 includes:

[0036] Threaded block 33 is rotatably connected to the top of power insulator 1;

[0037] Bolt 36 is threaded onto the inner wall of threaded block 33. When the power insulator 1 is placed in the required position, if the position presses against lever 35, it will drive threaded block 33 to rotate around bearing 34, causing the two threaded blocks 33 to move closer to the middle position, thereby achieving convenient and quick calibration, greatly improving the calibration efficiency during the installation process, and reducing calibration time and labor costs.

[0038] A bearing 34 is rotatably connected between the threaded block 33 and the top of the power insulator 1.

[0039] A lever 35 is fixedly connected to the outer wall of the threaded block 33, and a bracket 31 is fixedly connected to the outer wall of the base 2. When the threaded block 33 is disassembled, the descent of the power insulator 1 will cause the elasticity of the spring 32 to drive the threaded block 33 to reset. This design makes the disassembly process simple and convenient, reduces the difficulty of maintaining and replacing the power insulator 1, and improves work efficiency.

[0040] A spring 32 is fixedly connected to the top of the bracket 31, and the outer wall of the spring 32 is fixedly connected to the outer wall of the threaded block 33.

[0041] The number of threaded blocks 33, bearings 34, springs 32, levers 35 and bolts 36 are all two, and the two sets are arranged opposite to each other. The coordinated action of calibration mechanism 3 and limiting mechanism 4 not only realizes calibration and fixation during installation, but also enhances the stability of the power insulator 1 in the overall structure. It effectively resists the shaking caused by wind from multiple aspects, reduces the risk of the power insulator 1 falling off, and ensures the safety and stability of power transmission.

[0042] When the required position is pressed onto the lever 35, it will cause the threaded block 33 to rotate. The threaded block 33 rotates around the bearing 34, causing the two threaded blocks 33 to move closer to the middle position, which facilitates calibration. When the threaded block 33 is removed, the descent of the power insulator 1 will cause the elasticity of the spring 32 to reset the threaded block 33, which facilitates disassembly.

[0043] When the two threaded blocks 33 are close together, the bolt 36 is rotated to bring the two bolts 36 closer together, thereby fixing the desired installation position.

[0044] Example 2, please refer to Figure 1-8 Based on Embodiment 1, the present invention provides a technical solution:

[0045] The outer wall of the base 2 is fixedly connected to the limiting mechanism 4. After the two threaded blocks 33 are close together, the bolts 36 are rotated to bring the two bolts 36 closer together, which can initially fix the required installation position. Then, the telescopic machine 45 is powered on and started, which drives the telescopic rod 46 to extend and retract. By pulling down the pressure rod 44, the bending chamber 41 is compressed, causing the connecting pipe 42 and the air bladder 43 to descend. When the air bladder 43 is compressed to the required installation position, it can increase the fixation of the power insulator 1. At the same time, the pressure rod 44 compresses the bending chamber 41, causing the gas in it to enter the air bladder 43 through the connecting pipe 42, causing the air bladder 43 to inflate and fit against the bolts 36 and the outer wall of the required fixing position, further strengthening the fixing effect and effectively preventing the power insulator 1 from shaking or even falling off due to wind or other factors.

[0046] The limiting mechanism 4 includes a zigzag chamber 41, the bottom of which is fixedly connected to the outer wall of the base 2, and a connecting pipe 42 is fixedly connected to the top of the zigzag chamber 41. An airbag 43 is fixedly connected to the top of the connecting pipe 42.

[0047] A telescopic mechanism 45 is fixedly connected to the outer wall of the base 2. A telescopic rod 46 is movably connected to the top of the telescopic mechanism 45. A pressing rod 44 is movably connected to the top of the telescopic rod 46. The outer wall of the pressing rod 44 is fixedly connected to the top of the bending chamber 41.

[0048] After the bolt 36 approaches, the telescopic machine 45 is powered on and starts to drive the telescopic rod 46 to extend and retract. After the telescopic machine 45 pulls the pressure rod 44 down through the telescopic rod 46, it will squeeze the bending chamber 41, which will cause the connecting pipe 42 and the air bladder 43 to descend. When the air bladder 43 descends and squeezes to the required installation position, it will increase the fixation of the power insulator. Moreover, when the pressure rod 44 squeezes the bending chamber 41, the gas in the bending chamber 41 will enter the air bladder 43 through the connecting pipe 42, which will cause the air bladder 43 to inflate. When the air bladder 43 inflates, it will adhere to the outer wall of the bolt 36 and the required fixing position, thereby fixing them.
