Description

Technical Field

[0001] This utility model relates to the field of insulator measurement technology, and in particular to a live detection mechanism for power distribution line insulators. Background Technology

[0002] Ensuring that insulators are in good condition is crucial for the stable operation of power distribution lines. The performance of insulators directly affects the insulation performance, safety, and reliability of power distribution lines. In practical applications, a live-line testing mechanism for power distribution line insulators typically requires the following technologies:

[0003] 1. Contact detection technology: Using specially designed detection probes, such as resistance probes and electric field induction probes, to directly contact or approach the surface of the insulator to measure parameters such as the resistance and surface electric field distribution of the insulator;

[0004] 2. Optical Inspection Technology: Using equipment such as high-definition cameras and infrared thermal imagers, optical imaging inspection is performed on insulators. High-definition cameras can capture images of the insulator's appearance, and image analysis can identify visible defects such as cracks, damage, and dirt.

[0005] 3. Data processing and analysis technology: Microprocessors and data analysis software are used to process and analyze the data acquired by contact detection and optical detection.

[0006] When testing existing insulators, operators need to climb to a high place and extend their bodies outwards to allow the probe to contact the insulator, which is inconvenient and dangerous. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a live-line testing mechanism for power distribution line insulators, solving the technical problem that existing insulator testing requires operators to climb to a high position and extend their bodies outwards to allow the probe head to contact the insulator, which is inconvenient and dangerous.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A live-line detection mechanism for power distribution line insulators includes a support frame, a sliding frame symmetrically slidably mounted on the support frame, rubber wheels symmetrically rotatably mounted on the sliding frame, a bidirectional threaded rod rotatably mounted on the support frame, a motor fixedly mounted on the support frame, a control box fixedly mounted on the support frame, a camera fixedly mounted on the support frame, a first transmission rod installed between the two rubber wheels, a gear set installed between the output shaft of the motor and the first transmission rod, a detection rod fixedly mounted on the sliding frame, and a detection head installed at the end of the detection rod.

[0010] Preferably, the two sliding brackets are threaded to both ends of the bidirectional threaded rod.

[0011] Preferably, a dial ring is fixedly installed on the bidirectional threaded rod.

[0012] Preferably, a second transmission rod is fixedly installed between the two rubber wheels.

[0013] Preferably, a wire spool is fixedly installed on the second transmission rod.

[0014] Preferably, a first transmission wheel is fixedly mounted on the first transmission rod.

[0015] Preferably, a second transmission wheel is fixedly installed on the second transmission rod.

[0016] Preferably, a drive belt is installed between the second drive wheel and the first drive wheel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Rotating the dial ring causes the bidirectional threaded rod to rotate. Two sliding brackets are threadedly connected to both ends of the bidirectional threaded rod. Therefore, rotating the dial ring can make the two sliding brackets slide inward or outward simultaneously. After adjusting the rubber wheels at both ends according to the line spacing, the rubber wheels at both ends are mounted on the high-voltage line. Then, a signal is sent to the dial ring via the remote control, and the dial ring starts the motor. The motor will drive the first transmission rod to rotate through the gear set. The first transmission rod will drive the rubber wheels at both ends to rotate and move along the high-voltage line. The situation of the probe head can be seen through the camera. When the probe head is seen to be in contact with the insulator, a measurement can be taken, which achieves the effect of convenient measurement and reduced danger.

[0019] Second, during the movement, the first transmission rod will drive the first transmission wheel to rotate, the first transmission wheel will drive the second transmission wheel to rotate via the transmission belt, and the second transmission wheel will drive the spool to rotate via the second transmission rod. The spool rotates to complete the winding and unwinding of the measuring wire, achieving the effect of automatically winding and unwinding the measuring wire according to the usage requirements.

[0026] This application provides a live-line testing mechanism for power distribution line insulators, effectively solving the technical problem that existing insulator testing requires operators to climb to a high position and extend their bodies outwards to allow the probe head to contact the insulator, which is inconvenient and dangerous. Rotating the dial ring causes the bidirectional threaded rod to rotate. Two sliding brackets are threadedly connected to both ends of the bidirectional threaded rod, so rotating the dial ring allows the two sliding brackets to slide inwards or outwards simultaneously. After adjusting the rubber wheels at both ends according to the line spacing, the rubber wheels are mounted on the high-voltage line. Then, a signal is sent to the dial ring via a remote control, activating the motor, which will then... The gear set drives the first transmission rod to rotate, which in turn drives the rubber wheels at both ends to rotate, moving the probe along the high-voltage line. The camera can monitor the probe's position, and measurement can be performed when the probe contacts the insulator, achieving convenient measurement and reduced danger. During movement, the first transmission rod drives the first transmission wheel to rotate, which in turn drives the second transmission wheel to rotate via a transmission belt. The second transmission wheel then drives the spool to rotate via the second transmission rod. The rotation of the spool completes the winding and unwinding of the measuring wire, achieving automatic winding and unwinding of the measuring wire according to usage requirements.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that existing insulator testing requires operators to climb to a high position and extend their bodies outwards to allow the probe head to contact the insulator, which is inconvenient and dangerous. The overall idea is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a live detection mechanism for power distribution line insulators, including a bracket 1, a sliding frame 2 symmetrically slidably mounted on the bracket 1, rubber wheels 3 symmetrically rotatably mounted on the sliding frame 2, and a bidirectional threaded rod 4 rotatably mounted on the bracket 1.

[0030] A motor 6 is fixedly mounted on the bracket 1, a control box 7 is fixedly mounted on the bracket 1, a camera 8 is fixedly mounted on the bracket 1, a first transmission rod 9 is installed between two rubber wheels 3, a gear set 11 is installed between the output shaft of the motor 6 and the first transmission rod 9, a detection rod 12 is fixedly mounted on the sliding frame 2, and a detection head 13 is installed at the end of the detection rod 12.

[0031] Two sliding frames 2 are threaded to both ends of a bidirectional threaded rod 4. A dial ring 5 is fixedly installed on the bidirectional threaded rod 4. A second transmission rod 14 is fixedly installed between two rubber wheels 3. A spool 15 is fixedly installed on the second transmission rod 14. A first transmission wheel 16 is fixedly installed on the first transmission rod 9. A second transmission wheel 17 is fixedly installed on the second transmission rod 14. A transmission belt 18 is installed between the second transmission wheel 17 and the first transmission wheel 16.

[0032] Support 1: As the main support structure of the entire testing mechanism, it provides the installation foundation for components such as sliding frame 2, bidirectional threaded rod 4, motor 6, control box 7, and camera 8, ensuring that each component maintains a stable relative position during the testing process and guaranteeing the smooth progress of the testing work;

[0033] Sliding bracket 2: Symmetrically slidably mounted on bracket 1. Through threaded connection with both ends of bidirectional threaded rod 4, it can slide inward or outward simultaneously when bidirectional threaded rod 4 rotates, thereby adjusting the distance between the two sliding brackets 2 to adapt to high-voltage lines with different line spacings, providing an adjustable installation position for rubber wheel 3, and ensuring that the testing mechanism can be mounted on high-voltage lines of different specifications.

[0034] Rubber wheel 3: Rotatably mounted on sliding frame 2, in direct contact with high voltage line, rotates under the drive of motor 6, enabling the entire detection mechanism to move on high voltage line, realizing the detection of insulators at different positions. Its rubber material can increase the friction with high voltage line, ensuring that the mechanism will not easily slip during the detection process, and at the same time has a certain insulation performance to ensure detection safety.

[0035] Bidirectional threaded rod 4: Rotatably mounted on bracket 1, it drives the two sliding frames 2 connected to it by rotation to slide inward or outward simultaneously, so as to achieve precise adjustment of the distance between the sliding frames 2. The dial ring 5 is fixed on the bidirectional threaded rod 4, so that the operator can manually rotate the bidirectional threaded rod 4, or indirectly control the motor 6 to rotate the bidirectional threaded rod 4 after receiving the remote control signal, thereby adjusting the mounting position of the detection mechanism on the high voltage line.

[0036] Ring 5: Fixed on the bidirectional threaded rod 4, serving as an operating component for manually adjusting the rotation of the bidirectional threaded rod 4. This allows operators to manually rotate the bidirectional threaded rod 4 according to the line spacing of the high-voltage line to adjust the position of the sliding bracket 2. At the same time, it can also receive remote control signals to start the motor 6, thereby realizing electric control of the rotation of the bidirectional threaded rod 4, making operation more convenient.

[0037] Motor 6: Fixedly mounted on bracket 1, serving as the power source for the detection mechanism to move on the high-voltage line. Its output shaft is connected to the first transmission rod 9 through gear set 11, converting electrical energy into mechanical energy, driving the first transmission rod 9 to rotate, which in turn drives the rubber wheel 3 to rotate, thus enabling the detection mechanism to move on the high-voltage line.

[0038] Control box 7: Fixedly mounted on bracket 1, it integrates control circuit, signal receiving and processing module, etc., and is used to control the start, stop and speed of motor 6, while processing the signals sent by remote control, coordinating the work between various components, and ensuring that the detection mechanism runs according to the set program.

[0039] Camera 8: Fixedly mounted on bracket 1, used to capture the status of probe 13 in real time. Operators can observe the images captured by camera 8 to determine whether probe 13 is in contact with insulator, thereby determining whether measurement can be performed. This provides a visual basis for the detection operation, facilitates remote monitoring of the detection process by operators, and reduces the danger of operators approaching high-voltage lines for detection.

[0040] First transmission rod 9: Installed between two rubber wheels 3, one end is connected to the output shaft of motor 6 through gear set 11. Under the drive of motor 6, it rotates, driving the rubber wheels 3 at both ends to rotate synchronously, realizing the movement of the detection mechanism on the high-voltage line. At the same time, a first transmission wheel 16 is fixedly installed on the first transmission rod 9, which is connected to the second transmission wheel 17 through transmission belt 18, transmitting power to the second transmission rod 14 and the spool 15 to realize the winding and unwinding of the measuring wire.

[0041] Gear set 11: Installed between the output shaft of motor 6 and the first transmission rod 9, it plays the role of transmitting power and changing speed. It adjusts the speed and torque output by motor 6 appropriately to meet the speed and torque requirements required for rubber wheel 3 to drive the detection mechanism to move smoothly on the high-voltage line, thus ensuring the stability and reliability of the detection mechanism.

[0042] Detection rod 12: It is fixedly installed on the sliding frame 2, and the detection head 13 is installed at its end. It serves to support and position the detection head 13, so that the detection head 13 can accurately approach and contact the insulator to measure relevant parameters.

[0043] Detector head 13: Installed at the end of the detector rod 12, it is connected to the detector via a wire and is used to contact the insulator and measure the relevant electrical parameters of the insulator. It is a key component for obtaining detection data.

[0044] The second transmission rod 14 is fixedly installed between two rubber wheels 3, with both ends connected to the rubber wheels 3 respectively, serving as a support and transmission mechanism. At the same time, a spool 15 and a second transmission wheel 17 are fixedly installed on the second transmission rod 14. When the first transmission wheel 16 drives the second transmission wheel 17 to rotate through the transmission belt 18, the second transmission rod 14 drives the spool 15 to rotate, thereby realizing the winding and unwinding of the measuring wire.

[0045] Wire spool 15: Fixedly installed on the second transmission rod 14, used for winding the measuring wire. During the movement of the detection mechanism, as the second transmission rod 14 rotates, the wire spool 15 rotates synchronously, automatically winding and unwinding the measuring wire according to the detection requirements, avoiding problems such as tangling or dragging of the measuring wire during the detection process that affect the detection operation.

[0046] First transmission wheel 16: Fixedly installed on the first transmission rod 9, and connected to the second transmission wheel 17 through the transmission belt 18. When the first transmission rod 9 rotates, the first transmission wheel 16 rotates accordingly, and transmits power to the second transmission wheel 17 through the transmission belt 18, thereby driving the second transmission rod 14 and the spool 15 to rotate, realizing the automatic winding and unwinding function of the measuring wire.

[0047] Second transmission wheel 17: Fixedly installed on the second transmission rod 14, connected to the first transmission wheel 16 through the transmission belt 18, receiving the power transmitted by the first transmission wheel 16, driving the second transmission rod 14 and the spool 15 to rotate, completing the winding and unwinding of the measuring wire.

[0048] Transmission belt 18: Connects the first transmission wheel 16 and the second transmission wheel 17. When the first transmission wheel 16 rotates, the second transmission wheel 17 rotates synchronously through the transmission action of the transmission belt 18, thereby transmitting the power of the first transmission rod 9 to the second transmission rod 14 and the spool 15, realizing the power transmission required for the winding and unwinding function of the measuring wire.

[0049] Working principle:

[0050] The first step is to connect the probe 13 to the detector via a wire. Before connection, the wire is wound around the spool 15. Rotating the dial ring 5 will rotate the bidirectional threaded rod 4. The two sliding brackets 2 are threadedly connected to both ends of the bidirectional threaded rod 4, so rotating the dial ring 5 can make the two sliding brackets 2 slide inward or outward simultaneously. After adjusting the rubber wheels 3 at both ends according to the line spacing, the rubber wheels 3 at both ends are mounted on the high-voltage line. Then, a signal is sent to the dial ring 5 via the remote control, and the dial ring 5 starts the motor 6. The motor 6 will drive the first transmission rod 9 to rotate through the gear set 11. The first transmission rod 9 will drive the rubber wheels 3 at both ends to rotate and move on the high-voltage line. The situation of the probe 13 can be seen through the camera 8. When the probe 13 is seen to be in contact with the insulator, a measurement can be performed, achieving the effect of convenient measurement and reduced danger.

[0051] In the second step, during the movement, the first transmission rod 9 will drive the first transmission wheel 16 to rotate. The first transmission wheel 16 will drive the second transmission wheel 17 to rotate through the transmission belt 18. The second transmission wheel 17 will drive the spool 15 to rotate through the second transmission rod 14. The spool 15 rotates to complete the winding and unwinding of the measuring wire, achieving the effect of automatically winding and unwinding the measuring wire according to the usage requirements.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
