Description

Technical Field

[0001] This invention relates to the field of power safety technology, and in particular to a gravity-sliding capacitive voltage detection device for starting voltage detection. Background Technology

[0002] The starting voltage of a capacitive voltage detector is a mandatory inspection item for electrical safety equipment. Existing testing processes and equipment suffer from several practical difficulties, as explained below: Traditional testing processes require disassembling the voltage detector, which is difficult to automate: Current testing procedures require the removal of the voltage detector's operating rod, leaving only the front contact electrode head for testing; voltage detector operating rods on the market are divided into two types: threaded connection type and telescopic type. Telescopic rods are easy to retract automatically after removal. Both types of structures can only be disassembled manually, making mechanical automation difficult to achieve, and large-scale testing requires a large amount of manual operation.

[0003] Poor stability of tooling support and unreliable electrode contact: When the head of the electroscope is fixed alone on the insulating support rod after the rod body is removed, the gap between the support rods is large and it is easy to sway left and right; the swaying will cause the contact electrode of the electroscope to be poorly connected or disconnected from the high-voltage metal ball electrode, resulting in electric field distortion during the test, distortion of the starting voltage data, and large repeated detection error.

[0004] Traditional fixed testing brackets lack versatility: existing test brackets are fixed structures, and the support spacing, support height, and tilt angle cannot be adjusted independently; the length, diameter, and weight of the capacitor detector rods vary greatly, and a single bracket cannot be adapted to all models. Changing workpieces requires manual disassembly and adjustment of parts, which is time-consuming and results in low testing efficiency.

[0005] The lack of an automatic verification mechanism for contact status poses safety and accuracy risks: manual observation of electrode contact status is impossible, and only a rough judgment can be made by visual inspection; poor electrode contact can easily cause discharge and abnormal noise during voltage boosting tests, which can damage the voltage detector and high-voltage testing equipment, and may also lead to misjudgment of the starting voltage, resulting in low standardization of testing. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a gravity-sliding capacitive voltage detection device for starting a capacitive voltage detector, enabling fully automatic starting voltage detection of the capacitive voltage detector without disassembling the entire unit.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a gravity-sliding capacitive electroscope starting voltage detection device, comprising a capacitive electroscope, which is movably mounted with a first U-shaped gravity slide and a second U-shaped gravity slide. Both the first and second U-shaped gravity slides are mounted to a servo slide via columns. A vertical lifting servo mechanism is mounted on the servo slide, which is mounted on a guide rail. A tap guide rod is mounted on the guide rail. The tap guide rod drives the column to move horizontally, and the vertical lifting servo mechanism drives the column to move vertically.

[0008] Furthermore, frame bases are installed at both ends of the guide rail, and universal casters with brakes are installed on the side of the frame base adjacent to the ground.

[0009] Furthermore, the interior of the second U-shaped gravity chute is provided with a baffle to prevent the capacitive electroscope from sliding.

[0010] Furthermore, a visual verification module is installed on the frame base on the same side as the second U-shaped gravity chute.

[0011] Furthermore, a fixed support is installed on the side of the second U-shaped gravity chute that is separate from the first U-shaped gravity chute.

[0012] Furthermore, a fixed bracket is installed on the fixed support, and the fixed bracket passes through the support rod.

[0013] Furthermore, a metal ball is installed on the side of the support rod adjacent to the second U-shaped gravity groove.

[0014] The beneficial effects of this invention are as follows: This device addresses the shortcomings of traditional equipment, such as the need to disassemble the pole, swaying support, unstable contact, poor specification compatibility, and easy collision damage. It adopts a gravity tilting and sliding operation without disassembly, combined with automatic distance and angle adjustment of the double support, and an integrated solution of visual contact verification, to achieve fully automatic start-up voltage detection of the capacitive voltage detector without disassembling the entire machine. No need to disassemble the operating lever, completely eliminating the manual disassembly process: The whole machine is placed directly on the U-shaped support mechanism for testing, without the need to separate the voltage detector and the operating lever, avoiding the problem of manual disassembly and assembly of threaded rods and telescopic rods, greatly reducing manual intervention, and adapting to automated production line loading and unloading.

[0015] The gravity-driven self-pressurizing structure ensures continuous and reliable electrode contact: the dual support mechanism adjusts to form an inclined slide, and the complete electroscope slides downward along the U-shaped support by its own gravity. The probe continuously presses against the high-voltage metal ball electrode, eliminating the problems of loose connection and disconnection caused by the swaying of the support rod. The electric field environment is stable, improving the repeatability and accuracy of the test data.

[0016] Dual-support automatic adjustment in both horizontal and vertical dimensions, universally applicable to all sizes, with two sets of support columns that can move horizontally and rise vertically independently. Automatic horizontal spacing adjustment: After visually recognizing the overall length of the electroscope pole, the system automatically adjusts the horizontal spacing between the two supporting columns to adapt to electroscopes of different total lengths. Automatic vertical height and angle adjustment: Based on the diameter and weight of the electroscope rod, the preset tilt angle parameters are matched. For lightweight electroscopes, the tilt angle is increased to ensure smooth sliding, while for heavy electroscopes, the tilt angle is decreased to reduce sliding impact and prevent the probe from violently hitting the high-voltage electrode, thus protecting the testing fixture and the workpiece being tested.

[0017] Visual real-time verification of electrode fit status, closed-loop automatic correction: An industrial vision camera is installed under the high-voltage electrode to collect real-time images of the contact between the electroscope probe and the high-voltage metal ball; when the system identifies abnormalities such as non-fit, offset, or gap, it automatically fine-tunes the support height to correct the tilt angle until the electrode is fully fitted before starting the voltage boost test, thus preventing data misjudgment caused by loose connection.

[0018] With no active pushing components, the equipment has a low failure rate and is easy to maintain: by eliminating active pushing structures such as cylinders and electric push rods, the feed is achieved entirely by the weight of the workpiece itself. With fewer moving parts, there are no problems with pushing impact or rebound jamming, which reduces wear and maintenance costs in the later stages.

[0019] High-voltage areas are unmanned and close-range operations are not required, improving operational safety: The entire process of automatic workpiece feeding, automatic positioning, automatic verification, and automatic voltage boosting and data acquisition is automated. Workers do not need to have close contact with the high-voltage test station, avoiding the risks of electric shock and workpiece ejection and collision, and meeting the requirements of standardized batch quality inspection.

[0020] Eliminate the impact of telescopic voltage detector length changes on automatic positioning and avoid collisions or contact failures caused by rigid mechanical contact at a fixed point: During automatic handling, posture adjustment, and movement, the telescopic rod of a telescopic capacitive voltage detector may axially elongate or retract due to inertia, vibration, and clamping effects, causing a change in the actual total length of the voltage detector from the pre-loaded identification length. If a robotic arm is used to hold the voltage detector and move it to a fixed point based on a pre-obtained length, the high-voltage contact position will deviate. When the voltage detector elongates, it is easy to cause a rigid collision between the probe and the high-voltage electrode; when it shortens, it may fail to make contact or make insufficient contact. This device adopts a gravity sliding contact method with non-fixed-point forced feeding. The voltage detector slides freely along a U-shaped groove until the probe actually contacts the high-voltage electrode. Its final contact position is adaptively determined by the actual length of the workpiece, without relying on high-precision positioning of the voltage detector's total length. This adapts to changes in the telescopic rod length, reducing the risk of collision damage and contact failure. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] Please see Figure 1 and Figure 2 A gravity-sliding capacitive electroscope starting voltage detection device includes a capacitive electroscope 1, which is movably mounted with a first U-shaped gravity slide 9 and a second U-shaped gravity slide 10. Both the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10 are mounted to a servo slide 8 via a column 2. A vertical lifting servo mechanism 7 is mounted on the servo slide 8, which is mounted on a guide rail 14. A tap guide rod 4 is mounted on the guide rail 14. The tap guide rod 4 drives the column 2 to move horizontally, and the vertical lifting servo mechanism 7 drives the column 2 to move vertically.

[0024] In one specific embodiment, the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10 are used to place the capacitive electroscope 1. That is, as the angle of the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10 is adjusted, the capacitive electroscope 1 can slide within the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10.

[0025] The first U-shaped gravity slide 9 is installed with one column, and the second U-shaped gravity slide 10 is installed with another column. A locking device 3 is installed on each column. A servo slide 8 is installed at the end of each column that is separated from the U-shaped gravity slide. Each servo slide 8 is equipped with a vertical lifting servo mechanism 7. The vertical lifting servo mechanism 7 drives the column to slide up and down vertically, while the tap guide rod 4 drives the two servo slides 8 to slide horizontally. This adjusts the angle of the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10, thereby adjusting the contact angle between the capacitive electroscope 1 and the metal ball 19.

[0026] In one specific implementation, the two sets of columns form an inclined slide by the height difference between the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10. The entire capacitive detector 1 does not need to be disassembled and can be placed directly in the slide. It slides down by its own weight, causing the front probe to press against the high-voltage electrode assembly at the end of the slide. When the slide of the capacitive detector 1 just ends with the metal ball 19, the rod of the capacitive detector 1 is stopped by the baffle 15 to prevent the capacitive detector 1 from continuing to slide down.

[0027] The position of the baffle 15 can be fixed. By manually adjusting the horizontal and vertical positions of the first U-shaped gravity slide 9 and the second U-shaped gravity slide 10 multiple times, the capacitive electroscope 1 is held in place by the baffle 15 when it just comes into contact with the metal ball 19.

[0028] In one specific implementation, the visual verification module 13 can be an industrial camera, positioned below the high-voltage electrode, used to identify the contact transition between the electroscope probe and the high-voltage electrode.

[0029] The guide rail 14 is equipped with a frame base 6 at both ends, and the frame base 6 is equipped with a braked universal wheel 5 on the side adjacent to the ground.

[0030] The second U-shaped gravity slide 10 is provided with a baffle 15 to prevent the capacitive electroscope 1 from sliding.

[0031] A visual verification module 13 is installed on the frame base 6 on the same side as the second U-shaped gravity chute 10.

[0032] A fixed support 16 is installed on the side of the second U-shaped gravity chute 10 that is separate from the first U-shaped gravity chute 9.

[0033] A fixed bracket 17 is installed on the fixed support 16, and the fixed bracket 17 is inserted through the support rod 18.

[0034] A metal ball 19 is installed on the side of the support rod 18 adjacent to the second U-shaped gravity groove 9.

[0035] In one specific implementation, the two sets of columns can slide independently horizontally along the guide rail 14 of the frame base 6, thereby adjusting the horizontal distance between the two columns according to the capacitive voltage detector 1, so as to adapt to capacitive voltage detectors 1 with different total length specifications. In one specific implementation, the vertical height of the two sets of columns can be adjusted independently, and a preset tilt angle is matched according to the weight of the capacitive electroscope 1 and the rod diameter, using geometric formulas: α = arctan [(h1−h2) / L]; The height of the column is automatically calculated and controlled. The light capacitive electroscope 1 increases the tilt angle to ensure smooth sliding, while the heavy electroscope reduces the tilt angle to buffer the sliding impact and avoid damage to the probe.

[0036] The U-shaped slide rail completely supports the entire capacitive voltage detector without disassembling the operating rod, eliminating the need for manual disassembly of the operating rod. The starting voltage test can be completed without separating the voltage detector head from the operating rod.

[0037] The visual verification module acquires electrode contact images in real time and identifies loose connections, misalignments, and gap abnormalities. When the contact is unqualified, the control system automatically fine-tunes the column height to correct the tilt angle and completes gravity sliding fit again, forming a closed-loop correction mechanism for the contact state. Only after the contact is qualified will the pressure test be started. The working principle of a gravity-sliding capacitive electroscope starting voltage detection device is as follows: The automated feeding mechanism transports the complete, unremoved capacitive voltage detector 1 to the loading positions of the first U-shaped gravity chute 9 and the second U-shaped gravity chute 10. The visual verification module 13 collects the overall length and rod diameter appearance information of the voltage detector, thereby facilitating the operator to determine the distance and height difference between the two columns, i.e., the tilt angle. The capacitive electroscope 1 slides smoothly down the slide groove under its own weight, and the front contact electrode continuously presses the high-voltage metal ball 19, maintaining a close fit by its own weight, and is not affected by the slight shaking of the column. The visual verification module 13 below the metal ball 19 captures the electrode contact image to determine whether it is fully bonded. If there are gaps, misalignments or other poor contact problems, the height of the two columns is adjusted, the tilt angle is corrected, and gravity sliding bonding is completed again until the contact state is qualified.

[0038] After the visual verification module 13 passes the inspection, the step-up transformer gradually increases the test voltage, collects the audible and visual start signal of the detector in real time, records the corresponding start voltage value when the audible and visual alarm is triggered, and stores and archives it. After the data collection for a single workpiece is completed, the servo mechanism adjusts the height of the two columns to level the slide, releases the tilt support, and the feeding robot transfers the electroscope to the unloading area, waiting for the next workpiece to be loaded for cyclic inspection.

[0039] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
