Description

Technical Field

[0001] The present invention relates to the technical field of terminal detection, in particular to a wiring device for terminal detection. Background Art

[0002] During the construction of transmission lines, the performance of specific components in the power system needs to be regularly tested to ensure overall health. For example, the safety and reliability of the working status of equipment such as transformers, current transformers, and voltage transformers need to be tested.

[0003] Currently, insulation resistance testing is mainly done manually. The test equipment must first be powered off, and then personnel use a crane to manually clamp the wire clamps to the terminals of the device under test through insulation measures. After the test is completed, the process is repeated to remove the wires. This process has the following shortcomings: 1. Manual disassembly and assembly of the wire clamp is cumbersome, time-consuming and labor-intensive, and manual operation poses a major safety hazard to construction; 2. In some substations with complex environments, it is difficult to coordinate cranes to transport personnel to the relevant heights of designated facilities. The site adaptability is poor, and there are problems such as high labor costs, the need to select maintenance routes and inspect the site in advance, insufficient flexibility, and susceptibility to interference from unexpected factors.

[0004] In order to solve the above problems, the present application proposes a wiring device for terminal detection. Summary of the Invention

[0005] In order to solve the technical problems existing in the background technology, the present invention provides a wiring device for terminal detection.

[0006] The present invention provides a wiring device for terminal detection, comprising a first clamping portion and a second clamping portion. A first servo is installed internally at the lower end of the first clamping portion. One end of the second clamping portion is hinged to the first clamping portion, and the other end of the second clamping portion is transmission-connected to the output end of the first servo via a connecting rod assembly. The first servo drives the second clamping portion to rotate to adjust the angle between the first and second clamping portions. The lower ends of the first clamping portion and the second clamping portion are respectively provided with a first wiring hole and a second wiring hole. The upper ends of the two test wires are respectively fixed in the first wiring hole and the second wiring hole, and the lower ends of the two test wires are connected to the ground test instrument. A second servo is provided inside the upper end of the first clamping portion. The second servo is fixedly mounted on a hook, and the hook is connected to an external suspension device through a suspension assembly. The output end of the second servo is fixed to the first clamping portion. The second servo drives the first clamping portion to rotate to adjust the direction of the angle opening between the first clamping portion and the second clamping portion. In response to the problem that traditional manual wiring relies on cranes and has high safety risks, this device achieves fully automatic clamping through dual servo drive. The first servo controls the clamping angle through the connecting rod assembly, which can adapt to terminals of different sizes. The second servo controls the rotation of the clamping part to ensure that the opening is precisely aligned with the terminal. It can adapt to wiring terminals of different inclination angles and horizontal directions. After the test line is fixed to the wiring hole with screws and nuts, it can form a closed loop with the ground instrument, eliminating the need for manual high-altitude wiring, thereby shortening the single wiring time and avoiding the risks of high-altitude operations.

[0007] As a further optimized solution of the present invention, the first clamping portion has a U-shaped cross-section, the second servo and the first servo are respectively mounted at the upper and lower ends of the U-shaped inner cavity of the first clamping portion, a circular hole is formed on the side of the lower end of the first clamping portion away from the first wiring hole, the output end of the first servo extends to the outside of the first clamping portion through the circular hole and is connected to the input end of the connecting rod assembly, and the output end of the connecting rod assembly is connected to the lower end of the second clamping portion; The U-shaped structure enhances the rigidity of the first clamping part, ensuring that it does not deform during clamping. The servos are installed at both ends of the inner cavity, with a compact layout and no interference. The circular hole provides a channel for the servo output shaft, and the connecting rod assembly is connected to the servo through the channel to transmit torque and ensure stable clamping force.

[0008] As a further optimized solution of the present invention, the upper end of the second clamping portion extends above the circular hole and is hinged to the U-shaped side of the first clamping portion through a connecting plate, and the side of the lower end of the second clamping portion away from the second wiring hole is hinged to the output end of the connecting rod assembly through a connecting strip; The connecting plate is hinged to the first clamping part through a pin shaft, allowing the second clamping part to rotate flexibly. The connecting bar forms a crank slider structure with the connecting rod assembly to ensure smooth transmission. For example, when the first servo drives the connecting rod assembly to move, the connecting bar can drive the second clamping part to rotate smoothly, avoiding clamping failure due to transmission jam.

[0009] As a further optimized solution of the present invention, the second steering gear has two coaxially aligned output ends, and both output ends of the second steering gear are fixedly mounted with steering discs, which are fixedly connected to the inner wall of the U-shaped side of the first clamping portion; The dual-output servos synchronously drive both sides of the U-shape through the steering wheel, ensuring uniform force when the first clamping part rotates, improving rotation accuracy. For example, when adjusting the opening direction, the synchronous rotation of the dual steering wheels can prevent the clamping part from tilting, which is beneficial to reducing the error of parallelism between the opening plane and the terminal surface.

[0010] As a further optimized solution of the present invention, the lower end of the first clamping portion has a first bent portion on a side away from the U-shaped opening, and the lower end of the second clamping portion has a second bent portion. When the angle between the first clamping portion and the second clamping portion is completely closed, the second bent portion is in contact with the end surface of the first bent portion. The bent portion forms a rigid stop when the clamp is closed to prevent damage to the terminal due to excessive clamping. The contacting end faces have been anti-slip treated to provide strong friction and ensure a secure clamping.

[0011] As a further optimized solution of the present invention, the connecting rod assembly includes a transmission arm and a transmission rod, one end of the transmission arm is fixed to the output end of the first steering gear by a fastener, and the two ends of the transmission rod are hinged to the lower end of the second clamping portion and the other end of the transmission arm respectively; The transmission arm and the transmission rod form a crank-connecting rod mechanism, which can convert the rotational motion of the servo into the swing of the second clamping part to achieve rapid clamping.

[0012] As a further optimized solution of the present invention, the suspension device is a drone, and the suspension assembly includes a hanging tube and an insulating rope. The insulating rope passes through the hanging tube, and the two ends of the insulating rope are respectively connected to the two side tripods of the drone. The hanging tube contacts the inner right angle of the L-shaped bend of the hook; The drone is suspended by an insulating rope, and the L-shaped structure of the lifting tube and the hook forms a stable suspension point to ensure the stable suspension of the device.

[0013] As a further optimized solution of the present invention, a power box is mounted on the first clamping portion, the power box includes a box body mounted on the first clamping portion, a battery body is mounted inside the box body, and the battery body supplies power to the first servo and the second servo through two power lines respectively; The battery body is a lithium polymer battery, and the power line adopts a shielding design to prevent electromagnetic interference with the servo control signal, ensuring stable operation in the strong electromagnetic environment of the substation.

[0014] As a further optimized solution of the present invention, a receiver for remotely receiving control commands of the drone remote controller is further installed inside the box body, and the receiver is electrically connected to the first servo and the second servo via a servo communication line; The receiver supports 2.4GHz wireless communication with a receiving distance of ≥100m and can receive remote control commands in real time. The communication line uses a waterproof connector with an IP65 protection grade, which is suitable for outdoor operations in rainy days to ensure stable command transmission.

[0015] As a further optimized solution of the present invention, a through hole is opened at the upper end of the box body for the power line and the servo communication line to pass through, and both sides of the box body are open and respectively installed with a first end plate and a second end plate, which clamp and limit the receiver; A cover plate is added to the through hole, and a sleeve hole suitable for the cable is opened on the cover plate, and the sleeve hole is sealed by a seal. The cover plate and the through hole are sealed tightly to prevent rainwater from seeping in. The end plate is fixed by a buckle, and the receiver can be quickly disassembled and assembled, which shortens the later maintenance time and can improve the installation stability of the receiver.

[0016] The wiring device for terminal detection proposed by the present invention has the following beneficial effects: The present invention drives the second clamping part to rotate by the first servo, and adjusts the opening direction of the clamping part in combination with the second servo, thereby realizing fully automatic clamping and positioning of the terminal to be tested. Compared with traditional manual wiring that requires power off and relies on a crane, the present invention completely avoids manual high-altitude operations through drone suspension and servo control, reducing labor costs while also reducing construction risks. It can adapt to terminal blocks of different sizes and continuously clamp them. After completing the relevant terminal inspection, the terminal block can be recycled for the next inspection, saving resources, saving time, and improving wiring efficiency. It is particularly suitable for intensive inspection scenarios in substations.

When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0022] In the field of terminal detection technology, traditional manual wiring methods have problems such as high risks of high-altitude operations, reliance on cranes, and low efficiency. The test wiring device proposed in this invention realizes automated and intelligent terminal detection through the innovative design of drone suspension and dual servo drive. The specific implementation method is as follows: like Figures 1-8 As shown, the device is mainly composed of a first clamping part 1 and a second clamping part 2, which are hinged with a connecting rod assembly 4 to form a clamping structure with an adjustable angle. The cross section of the first clamping part 1 is U-shaped, and the first steering gear 3 and the second steering gear 5 are respectively installed at the upper and lower ends of the inner cavity; The output end of the first servo 3 extends to the outside of the U-shape through the circular hole and is fixed to the transmission arm 41 of the connecting rod assembly 4. The transmission rod 42 drives the second clamping part 2 to rotate to adjust the clamping angle; The second steering gear 5 has two coaxial output ends, each of which is fixed with a steering wheel 12 and connected to the inner wall of the U-shaped side of the first clamping part 1, and is used to drive the clamping part to rotate as a whole and adjust the direction of the opening.

[0023] A first wiring hole 8 and a second wiring hole 9 are respectively provided at the lower end of the clamping part for fixing the test line. A first bending part 13 is provided at the lower end of the first clamping part 1, and a second bending part 14 is provided at the lower end of the second clamping part 2. When closed, the end faces of the two are in contact with each other to form a rigid stop and anti-slip structure.

[0024] like Figure 8 As shown, the suspension assembly includes a hanging tube 10 and an insulating rope 11. The insulating rope 11 passes through the hanging tube 10 and is connected to the UAV tripod. The hanging tube 10 contacts the inner right angle of the L-shaped bend of the hook 6 to form a stable hanging point. like Figure 7 and Figure 8As shown, the power box 7 is installed on the outside of the first clamping part 1, and the battery body 72 is placed in the box body 71 to power the dual servos. At the same time, the integrated receiver 73 receives the instructions of the drone remote control and controls the servo movement through the servo communication line. The first end plate 75 and the second end plate 76 clamp the limit receiver 73 on both sides of the box body 71, and a seal is provided at the through hole 74 to prevent rainwater from seeping in.

[0025] When it is necessary to test the resistance of the equipment terminal, fix the two test wires in the first wiring hole 8 and the second wiring hole 9 respectively, and lift the lifting tube 10 through the insulating rope 11 on the drone tripod so that the lifting tube 10 contacts the inner right angle of the L-shaped bend of the hook 6, and then use the drone to drive the device to rise as a whole; By controlling the drone to fly, the device is raised to just above the terminal to be tested. Then, the drone remote control controls the receiver 73 to issue a command to the first servo 3. The output end of the first servo 3 drives the transmission arm 41 to rotate 90° counterclockwise. The transmission arm 41 and the transmission rod 42 form a crank-connecting rod structure, so that the rotation of the transmission arm 41 drives the transmission rod 42 to move. The transmission rod 42 drives the second clamping part 2 to rotate counterclockwise. At this time, the second bent portion 14 at the lower end of the second clamping part 2 is separated from the first bent portion 13 at the lower end of the first clamping part 1, and the angle between the first clamping part 1 and the second clamping part 2 reaches its maximum. The drone remote control receiver 73 then issues a command to the first servo 3. The first servo 3 drives the first clamping part 1 to rotate clockwise by rotating the two steering wheels 12. When the first clamping part 1 is adjusted to the appropriate position, the drone slowly descends, so that the first clamping part 1 and the second clamping part 2 approach the two sides of the terminal to be tested. The drone remote control receiver 73 issues a command to the first servo 3, driving the transmission arm 41 to rotate clockwise, so that the transmission rod 42 drives the second clamping part 2 to rotate clockwise. The angle between the second clamping part 2 and the first clamping part 1 gradually decreases until the first clamping part 1 and the second clamping part 2 clamp the surface of the terminal to be tested, and the entire device can be fixed on the upper part of the terminal. Then the drone descends, driving the lifting tube 10 to vertically detach from the L-shaped bend of the hook 6, and then moves horizontally after detachment, returning to the take-off point, and then the lower ends of the two test lines are connected to the bottom test instrument for testing. When the test is completed, the drone takes off, lifts the lifting tube 10, and the lifting tube 10 contacts the right angle inside the L-shaped bend of the hook 6 again. At this time, the drone remote control controls the receiver 73 to issue a command to the first servo 3, driving the transmission arm 41 to rotate counterclockwise, and the transmission rod 42 drives the second clamping part 2 to rotate counterclockwise, so that the angle between the second clamping part 2 and the first clamping part 1 is enlarged, and the drone drives the device to rise vertically as a whole and return to the take-off point, and the test process is completed.

[0026] In one embodiment, during the annual inspection of a 500kV substation, the device was used to perform insulation resistance tests on 120 terminals; Traditional solution: Requires four people and a crane, single-terminal testing takes 15 minutes, and there is a risk of tools falling due to three overhead operations. This device solution: 2 people operate the drone, and a single terminal test takes 3 minutes without any safety incidents. The test efficiency is increased by 5 times, and the labor cost is reduced by 50%; By integrating mechanical structure with intelligent control, the device provides a safe and efficient solution for terminal detection. It is particularly suitable for complex scenarios such as urban substations and transmission lines in mountainous areas, and promotes the development of power detection towards intelligence.

[0027] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
