Description

Technical Field

[0001] This invention relates to the field of electrical automation, specifically to a testing device for electrical automation equipment. Background Technology

[0002] When inspecting electrical automation equipment, it is often only possible to manually inspect the two sides of the equipment using testing equipment. However, the wiring and control modules of many automation devices are installed on the top, making it very inconvenient to inspect the top of the electrical automation equipment. The existing operating methods mostly use A-frame ladders for manual inspection, which not only poses safety risks but also has poor inspection flexibility, limited functionality, and certain limitations. It cannot thoroughly inspect the equipment and is inconvenient for people to operate and use.

[0003] To solve the above problems, after searching, Chinese Patent No. CN215768694U was found, which discloses a testing device for electrical automation equipment. The device includes a testing frame, a first support frame and a second support frame. Several second hydraulic cylinders are installed on both sides of the inside of the testing frame. One end of the second hydraulic cylinder is connected to a slider. The slider is movably connected to the inside of the first support frame and the second support frame. A base is installed at the bottom of both the first support frame and the second support frame.

[0004] Although the above-mentioned device can use cameras and lights to photograph and inspect automated equipment, in actual use, the camera is placed directly above the electrical equipment being inspected, and the electrical equipment being inspected is stationary, so it cannot display multiple degrees of freedom. It can only obtain images from a top-down angle, and it is easy to miss whether fault lights such as voltage and current on the side, back, bottom and corners of the equipment are lit. It is also easy to miss defects such as cracks, loose wiring, deformation, and corrosion, resulting in incomplete inspection. Summary of the Invention

[0008] Furthermore, the drive gear is meshed with a driving gear on one side, and the rotation detection mechanism also includes a drive motor fixed on the base, and the output end of the drive motor is connected to the driving gear.

[0009] Furthermore, the multi-directional tilt detection mechanism includes three sets of drive cylinders fixed inside the rotating box, and the three sets of drive cylinders are distributed in an equilateral triangle structure. Each of the three sets of drive cylinders has a connecting platform on its output end, and the connecting platform is located at the bottom of the composite clamping platform.

[0010] Furthermore, the connecting platform includes an upper U-shaped seat connected to the composite clamping platform and a lower U-shaped seat connected to the output end of the drive cylinder. A connecting shaft is provided between the lower U-shaped seat and the upper U-shaped seat, and the connecting shaft has a "+" shaped structure. The lower U-shaped seat and the upper U-shaped seat are movably connected through the connecting shaft. The composite clamping platform is driven to reciprocate and swing through multiple sets of drive cylinders and connecting platforms.

[0011] Furthermore, the composite clamping platform includes a drive disk disposed at the bottom of the platform, and an outer cover is provided on the outer side of the bottom of the platform. At the same time, a motor device is provided at the bottom of the outer cover, and a transmission gear is also installed inside the outer cover. The output shaft of the motor device is connected to the transmission gear. The drive disk has a circular structure and is movably connected inside the outer cover through a rotating shaft. At the same time, a fan-shaped rack is provided on one side of the drive disk. The size of the fan-shaped rack and the transmission gear are matched, and the fan-shaped rack and the transmission gear mesh.

[0012] Furthermore, the drive disk has multiple sets of drive channels equidistantly arranged, and the drive channels have an arc-shaped structure. Passive columns are inserted in each of the multiple sets of drive channels, and a limiting platform is fixed on the passive column. The limiting platform is fixed to the bottom of the clamping seat, and the size of the limiting platform and the limiting channel are matched. At the same time, the limiting platform is slidably connected in the limiting channel.

[0013] Furthermore, the rotating drive disk drives multiple sets of clamping seats to move synchronously in opposite directions through multiple sets of drive channels and passive columns to clamp and release the device body. The clamping seats have an "L" shaped structure and a rubber pad on the front of the clamping seats. The surface of the rubber pad has a serrated structure.

[0014] Furthermore, the detection frame includes a top frame connected to the detection camera, and an adjustment arm is provided at the bottom of the top frame. A limit track is provided on the adjustment arm. The detection frame also includes a support column fixed on the base, and a limit seat is provided on the outside of the support column. The limit seat is slidably connected in the limit track. Multiple sets of studs are provided at the end of the limit seat, and the studs pass through the limit track and are fixed by screwing with nuts.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This solution utilizes the drive motor, active gear, and drive gear of the rotary detection mechanism, along with the transmission structure of the triangular rotating box, to drive the multi-directional tilt detection mechanism and the composite clamping platform to rotate. Simultaneously, it combines three sets of drive cylinders distributed in an equilateral triangle within the multi-directional tilt detection mechanism with the connecting platform's movable structure of a cross-shaped connecting shaft, driving the clamped equipment body to achieve multi-directional rotation and multi-angle swing, achieving multi-degree-of-freedom attitude adjustment. Combined with a fixed detection camera on the detection frame, it can comprehensively capture detection images of the equipment body from various angles, including top, side, bottom, and rear views, completely solving the problem of blind spots caused by a single top-down view. It allows for clear inspection of whether voltage, current, and fault indicator lights on the sides, back, bottom, and corners of the equipment body are lit normally, comprehensively checking for defects such as cracks, loose wiring, deformation, and corrosion in various parts of the equipment, greatly improving the comprehensiveness and completeness of the inspection.

[0016] 2. This solution utilizes the arc-shaped drive channel of the drive plate in the composite clamping platform, the driven column, and the linkage transmission structure between the limiting platform and the limiting channel. Driven by the motor device, transmission gears, and sector rack, multiple sets of clamping seats move synchronously in opposite directions or in opposite directions, accurately completing the stable clamping and rapid release of the equipment body. The serrated rubber pad on the front of the clamping seat increases the clamping friction, preventing the equipment body from shifting, shaking, or even falling off during multi-degree-of-freedom rotation and swing detection. This ensures the clarity and stability of the images captured by the detection camera. At the same time, it eliminates the need for manual adjustment of the equipment posture, automating multi-directional detection operations. This not only improves detection efficiency but also ensures that various hidden defects and function indicator statuses can be effectively detected, preventing defect omissions.

Detailed Implementation

[0019] Example 1

[0020] Please see Figures 1-9 This invention provides an electrical automation equipment testing device, including a base 100, a rotating testing mechanism 200 connected to the base 100, a multi-directional tilting testing mechanism 300 inside the rotating testing mechanism 200, and a composite clamping platform 400 mounted on the multi-directional tilting testing mechanism 300. The composite clamping platform 400 includes a platform 41, and a device body 700 is mounted on the platform 41. A testing camera 600 is mounted on the upper side of the device body 700, and a testing frame 500 is mounted on the outer side of the testing camera 600. The end of the testing frame 500 is fixed to the base 100. Multiple sets of clamping seats 44 are provided on the platform 41, and the device body 700 is clamped and fixed on the platform 41 by the multiple sets of clamping seats 44.

[0021] The rotating detection mechanism 200 includes a rotating box 21 rotatably connected to the base 100, and the rotating box 21 has a triangular structure. A drive gear 22 and a fixed disk 25 are respectively provided on the outside of the rotating box 21. Both the fixed disk 25 and the drive gear 22 have a circular structure. A bearing seat 27 is provided on the outside of the fixed disk 25, and multiple sets of fixed frames 26 are provided on the outside of the bearing seat 27. The bottom of the fixed frame 26 is screwed onto the base 100.

[0022] The drive gear 22 is meshed with the drive gear 24 on one side. The rotary detection mechanism 200 also includes a drive motor 23 fixed on the base 100, and the output end of the drive motor 23 is connected to the drive gear 24. The drive motor 23 drives the multi-directional tilt detection mechanism 300 and the composite clamp 400 to rotate through the drive gear 24 and the drive gear 22.

[0023] The multi-directional tilt detection mechanism 300 includes three sets of drive cylinders 31 fixed inside the rotating box 21. The three sets of drive cylinders 31 are distributed in an equilateral triangle structure. Each of the three sets of drive cylinders 31 has a connecting platform 32 at its output end. The connecting platform 32 is located at the bottom of the composite clamping platform 400.

[0024] The connecting platform 32 includes an upper U-shaped seat 321 connected to the composite clamping platform 400 and a lower U-shaped seat 322 connected to the output end of the drive cylinder 31. A connecting shaft 323 is provided between the lower U-shaped seat 322 and the upper U-shaped seat 321. The connecting shaft 323 has a "+" shaped structure. The lower U-shaped seat 322 and the upper U-shaped seat 321 are movably connected through the connecting shaft 323. The composite clamping platform 400 is driven to reciprocate and swing through multiple sets of drive cylinders 31 and the connecting platform 32.

[0025] like Figure 1-4 As shown: A multi-directional tilt detection mechanism 300 is formed by three sets of drive cylinders 31 arranged in an equilateral triangle structure inside the rotating box 21, together with a connecting platform 32. The connecting platform 32 forms a multi-dimensional movable connection structure with the cross-shaped connecting shaft 323 through the upper U-shaped seat 321, the lower U-shaped seat 322, and the upper U-shaped connecting shaft 323. This allows the drive cylinders 31 to drive the composite clamping platform 400 to swing freely in multiple directions, including forward, backward, left, right, and compound angles, during the telescopic movement. The equilateral triangle distribution of the drive cylinders 31 results in uniform force distribution and stable support, ensuring that the composite clamping platform 400 does not tilt or shift during attitude adjustment. The cross-shaped connecting shaft 323 can adapt to multi-angle rotation requirements and avoid motion interference, thereby realizing the multi-degree-of-freedom attitude display of the tested equipment. Combined with the detection camera 600, it fully covers the sides, back, bottom, and corners of the equipment, effectively eliminating blind spots and improving the comprehensiveness and accuracy of the detection.

[0026] The composite clamping platform 400 includes a drive disk 42 disposed at the bottom of a platform 41, and an outer cover 43 is provided on the outer side of the bottom of the platform 41. A motor device is provided at the bottom of the outer cover 43, and a transmission gear 423 is also installed inside the outer cover 43. The output shaft of the motor device is connected to the transmission gear 423. The drive disk 42 has a circular structure and is movably connected to the outer cover 43 through a rotating shaft. A sector rack 424 is provided on one side of the drive disk 42. The size of the sector rack 424 and the transmission gear 423 are matched, and the sector rack 424 and the transmission gear 423 mesh.

[0027] like Figures 1-8 As shown: The drive motor 23, drive gear 24, and drive gear 22 of the rotary detection mechanism 200, in conjunction with the transmission structure of the triangular rotating box 21, drive the multi-directional tilt detection mechanism 300 and the composite clamping platform 400 to rotate. Simultaneously, combined with the three sets of drive cylinders 31 distributed in an equilateral triangle in the multi-directional tilt detection mechanism 300 and the movable structure of the connecting platform 32 of the cross-shaped connecting shaft 323, the clamped equipment body 700 is driven to achieve multi-directional rotation and multi-angle swing multi-degree-of-freedom attitude adjustment. With the detection camera 600 fixed on the detection frame 500, the detection images of the equipment body 700 from various angles such as top, side, bottom, and back can be collected from all directions. This completely solves the problem of blind spots caused by a single top view. It can clearly check whether the voltage, current, fault lights and other function indicator lights on the side, back, bottom and corners of the equipment body 700 are lit normally. It can comprehensively check for defects such as cracks, loose wiring, deformation, and corrosion in various parts of the equipment, greatly improving the comprehensiveness and completeness of the detection.

[0028] Multiple sets of drive channels 421 are equally spaced on the drive disk 42, and the drive channels 421 have an arc-shaped structure. Passive columns 422 are inserted in each set of drive channels 421, and a limiting platform 4221 is fixed on the passive column 422. The limiting platform 4221 is fixed to the bottom of the clamping seat 44, and the size of the limiting platform 4221 and the limiting channel 411 are compatible. At the same time, the limiting platform 4221 is slidably connected in the limiting channel 411.

[0029] The rotary drive disk 42 drives multiple sets of clamping seats 44 to move synchronously in opposite directions through multiple sets of drive channels 421 and passive columns 422 to clamp and release the equipment body 700. The clamping seat 44 has an "L" shaped structure and a rubber pad 441 is provided on the front of the clamping seat 44. At the same time, the surface of the rubber pad 441 has a serrated structure.

[0030] like Figures 2-7As shown: Through the linkage transmission structure of the arc-shaped drive channel 421, passive column 422, limit stage 4221 and limit channel 411 of the drive plate 42 in the composite clamping platform 400, multiple sets of clamping seats 44 move synchronously towards or away from each other under the drive of the motor device, transmission gear 423 and sector rack 424, to accurately and stably clamp and quickly release the equipment body 700. The rubber pad 441 with the sawtooth structure on the front of the clamping seat 44 increases the clamping friction, preventing the equipment body 700 from shifting, shaking or even falling off during multi-degree-of-freedom rotation and swing detection, ensuring the clear and stable image captured by the detection camera 600. At the same time, there is no need for manual adjustment of the equipment posture, and the multi-directional detection operation is completed automatically, which not only improves the detection efficiency, but also ensures that all kinds of hidden defects and function indicator status can be effectively detected, eliminating the problem of defect omission.

[0031] Working principle: When the electrical automation equipment testing device is working, the equipment body 700 is first placed on the platform 41 of the composite clamping platform 400. The motor device inside the outer cover 43 is started. The output shaft of the motor device drives the transmission gear 423 to rotate. The transmission gear 423 meshes with the fan-shaped rack 424 on one side of the drive disk 42, thereby driving the drive disk 42 to rotate inside the outer cover 43. When the drive disk 42 rotates, the multiple sets of drive channels 421 with arc-shaped structure on its surface move synchronously. The drive channels 421 drive the internally inserted passive columns 422 to move. The passive columns 422 slide in the limiting channel 411 of the platform 41 through the limiting platform 4221, thereby driving the multiple sets of L-shaped clamping seats 44 to move synchronously in opposite directions. Together with the serrated rubber pad 441 on the front of the clamping seat 44, the equipment body 700 is stably clamped and fixed.

[0032] Subsequently, the detection camera 600 on the detection frame 500 starts to perform detection on the equipment body 700. The drive motor 23 in the rotating detection mechanism 200 drives the drive gear 24 to rotate. The drive gear 24 meshes with the drive gear 22, which in turn drives the triangular rotating box 21 rotatably connected to the base 100 to rotate. When the rotating box 21 rotates, it drives the internal multi-directional tilt detection mechanism 300 and the composite clamping platform 400 to rotate synchronously. At the same time, the three sets of drive cylinders 31 distributed in an equilateral triangle in the multi-directional tilt detection mechanism 300 move synchronously or independently. The output end of the drive cylinder 31 is connected to the upper U-shaped seat 321 through the movable connection structure of the lower U-shaped seat 322 and the cross-shaped connecting shaft 323, which drives the composite clamping platform 400 and the clamped equipment body 700 to swing in multiple directions, realizing the attitude adjustment of the equipment body 700 with multiple degrees of freedom. With the cooperation of the detection camera 600, the equipment body 700 is detected from all directions. After the detection is completed, the motor device reverses to drive the clamping seat 44 to move synchronously in opposite directions to release the equipment body 700.

[0033] This solution utilizes a drive motor 23 within the rotary detection mechanism 200 to drive the active gear 24 and drive gear 22, which in turn causes the rotating box 21 to rotate the multi-directional tilt detection mechanism 300, the composite clamping platform 400, and the equipment body 700. Combined with the three sets of equilateral triangularly distributed drive cylinders 31 within the multi-directional tilt detection mechanism 300, and the connecting platform 32 structure with the cross-shaped connecting shaft 323, the equipment body 700 achieves multi-degree-of-freedom reciprocating oscillation adjustment. Furthermore, the detection camera 600 fixed on the detection frame 500 overcomes the limitation of only being able to capture images from above, allowing for comprehensive acquisition of the side views of the equipment body 700. Images of the back, bottom, and corners clearly show the illumination status of voltage, current, fault lights, and other function indicator lights on all sides of the device body 700, effectively avoiding blind spots in the detection. At the same time, the composite clamping platform 400, through the transmission structure of the drive plate 42, arc-shaped drive channel 421, passive column 422, and limit platform 4221, drives multiple sets of clamping seats 44 to move synchronously in opposite directions to clamp and fix the device body 700. The serrated rubber pad 441 enhances the clamping stability, ensuring that the device body 700 will not shift or loosen during multi-degree-of-freedom rotation and swing, thus guaranteeing the stability and reliability of the detection process. Example 2

[0034] Based on Example 1, such as Figures 10-11 As shown, The testing frame 500 includes a top frame 51 connected to the testing camera 600, and an adjusting arm 52 is provided at the bottom of the top frame 51. A limiting rail 54 is provided on the adjusting arm 52. The testing frame 500 also includes a support column 53 fixed on the base 100, and a limiting seat 55 is provided on the outside of the support column 53. The limiting seat 55 is slidably connected in the limiting rail 54. Multiple sets of studs 56 are provided at the end of the limiting seat 55, and the studs 56 pass through the limiting rail 54 and are fixed by screwing nuts.

[0035] The testing frame 500, through the combination structure of the top frame 51, adjusting arm 52 and support column 53, and with the limiting rail 54 on the adjusting arm 52, the limiting seat 55 on the outside of the support column 53, and the locking and fixing method of studs 56 and nuts, can realize flexible adjustment of the installation height and horizontal extension position of the testing camera 600. It can accurately adjust the detection height and shooting range of the testing camera 600 according to the different sizes and specifications of the equipment body 700. At the same time, the structure of the limiting seat 55 sliding in the limiting rail 54 and locking with the stud 56 is reliable in positioning and convenient in adjustment. It not only ensures the structural stability of the testing camera 600 in the multi-degree-of-freedom detection process, but also adapts to the detection needs of different models of electrical automation equipment, further expanding the applicability of the device and improving the accuracy of detection position adjustment and operation convenience.
