Description

Technical Field

[0001] This utility model relates to the field of insulator technology, and more specifically, to an automatic detection and transmission device for power frequency sparks in insulators. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a ground potential component, capable of withstanding voltage and mechanical stress. It is a special type of insulation control that plays a crucial role in overhead transmission lines. Insulators are primarily used to support and secure busbars to live conductors, ensuring sufficient distance and insulation between live conductors or between conductors and the ground. Insulators are typically made of glass or ceramic; those made of ceramic are called porcelain insulators. Before leaving the factory, insulators undergo high-voltage testing to verify their insulation performance.

[0003] Existing glass insulator insulation performance testing machines require placing the glass insulator on a support plate and support base, and then testing the insulation performance of the glass insulator by powering on through a power supply box. However, manual operation is required to place the glass insulator. Due to the high voltage output of the power supply box, electric shock accidents are prone to occur, making the operation unsafe. In addition, the testing efficiency is low, making it difficult to meet the testing needs of enterprises. Utility Model Content

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, an automatic detection and transmission device for power frequency sparks of insulators is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, an automatic insulator frequency spark detection and conveying device according to an embodiment of the present invention includes a frame 1 and a mechanical claw 16. A fixed platform 2 is welded to the middle of the interior of the frame 1. A drive roller and a rotating roller 15 are symmetrically rotatably connected to the surface of the fixed platform 2. A conveyor belt 4 is installed between the drive roller and the rotating roller 15. One end of the drive roller passes through one side of the fixed platform 2 and is connected to a first motor 3. A support beam 9 is welded to the middle of the top surface of the frame 1. A power supply box 8 is installed at the middle of the top of the support beam 9. Several sets of cylinders 10 are symmetrically installed on both sides of the bottom of the support beam 9. A fixing plate 11 is installed at the bottom of the cylinders 10. The width of the fixing plate 11 is greater than that of the conveyor belt 4. The conveyor belt is 4 widths. Inside the fixed plate 11, a sliding rod 7 and a lead screw 13 are installed on both sides respectively. One end of the lead screw 13 passes through one side of the fixed plate 11 and is connected to the second motor 12. Connecting arms 14 are sleeved on the outer periphery of both the lead screw 13 and the sliding rod 7. A movable plate 6 is welded to the bottom of the connecting arm 14. Several sets of mechanical claws 16 are symmetrically rotated and connected to both sides of the bottom of the movable plate 6. One end of the mechanical claw 16 passes through one side of the movable plate 6 and is connected to the third motor 19. A waste box 17 is fixedly installed in the middle of one side surface of the fixed platform 2 directly below the fixed plate 11. The waste box 17 is set up to collect and use unqualified porcelain insulators for subsequent processing.

[0028] In one embodiment, the mechanical claw 16 has an insulating layer 20 on its upper surface and a conductive layer on its lower surface. The conductive layer is made of conductive material, and the insulating layer 20 is made of insulating material. The conductive layer is also connected to the power supply box 8. The insulating layer 20 isolates the conductive layer from the output terminal of the third motor 19, preventing high voltage from damaging the motor. The power supply box 8 is also connected to the conductive layer, ensuring that the high voltage output from the power supply box 8 acts on the porcelain insulator between the conductive layers, thus improving detection accuracy. When a defective porcelain insulator is broken down, the detection equipment in the circuit (such as a leakage current detector for an insulating operating rod under high voltage or a multi-functional polarograph that requires high-precision measurement; since current detectors are diverse and their application technology is mature, they will not be described in detail, and personnel can choose for themselves) will detect an increase in output current. Therefore, the quality of the porcelain insulator can be determined by the change in current, thereby realizing automatic detection of power frequency sparks in the insulator.

[0029] In one embodiment, the power supply box 8 is electrically connected to the conductive layer on the surface of the mechanical claw 16, and high voltage is output to the porcelain insulator through the power supply box 8 to test the insulation performance of the porcelain insulator.

[0030] In one embodiment, a photoelectric counter 5 is installed on one side of the top of the fixed platform 2. The photoelectric counter 5 is set up to count the porcelain insulators. Personnel can also selectively set the photoelectric counter 5 at both ends of the conveyor belt 4 to count the number of input and output porcelain insulators respectively, thereby facilitating the judgment of the yield of porcelain insulators.

[0031] In one embodiment, an infrared detector 18 is installed at the middle position of the bottom surface of the movable plate 6. The infrared detector 18 is set up to detect the porcelain insulators on the conveyor belt 4, so as to facilitate the mechanical claw 16 to grasp and detect them.

[0032] In one embodiment, the bottom sides of the fixed plate 11 are symmetrically provided with slots for the connecting arm 14 to move. The slots are provided to facilitate the movement of the connecting arm 14, thereby ensuring that the moving plate 6 can be moved smoothly.

[0033] In one embodiment, the top of the connecting arm 14 has a T-shaped structure. The top structure of the connecting arm 14 is designed to ensure that it can move stably under the drive of the lead screw 13, thereby adjusting the moving plate 6 above the conveyor belt 4 and above the waste box 17. This facilitates the unloading of unqualified porcelain insulators, making it easier for subsequent personnel to handle them. It eliminates the need for secondary manual sorting, effectively reducing the labor intensity of personnel and improving work efficiency.

[0034] Working Principle: In actual use, the first motor 3 is started, driving the drive roller to rotate and moving the conveyor belt 4. Porcelain insulators are continuously placed at the input end of the conveyor belt 4. The conveyor belt 4 transports porcelain insulators. When the infrared detector 18 at the bottom center of the moving plate 6 detects a porcelain insulator, the first motor 3 is turned off, and the cylinder 10 is started. The cylinder 10 drives the moving plate 6 to move downward, so that the end of the porcelain insulator is between the two mechanical claws 16. The third motor 19 is started, driving the mechanical claws 16 to rotate to clamp the end of the porcelain insulator. The cylinder 10 drives the mechanical claws 16 to move upward to clamp the porcelain insulator. The power supply box 8 is turned on, and the power supply box 8 outputs high voltage to the porcelain insulator to test its insulation performance. After the test is completed, the qualified porcelain insulator can be put back on the conveyor belt 4, and the first motor 3 is turned on to transport the porcelain insulator for the next porcelain insulator. The device performs testing on the insulators, while unqualified porcelain insulators are held in place. The second motor 12 drives the lead screw 13 to rotate, which in turn moves the connecting arm 14. This causes the connecting arm 14 to move the moving plate 6 outward, allowing the moving plate 6 to move above the waste box 17. The mechanical claw 16 is then released to remove the unqualified porcelain insulators, which are then collected in the waste box 17 for subsequent processing. This effectively prevents the mixing of porcelain insulators from affecting their use and avoids the need for secondary screening. It effectively reduces the labor intensity of personnel and improves work efficiency. At the same time, the participation of the mechanical claw 16 effectively ensures the safety of personnel and avoids accidents. The device as a whole has the advantages of safe operation, high testing efficiency, and convenient operation.
