Description

Technical Field

[0001] This invention relates to the field of live-line detection technology, and in particular to a contact-type device for detecting the live-line status of equipment based on passive electromagnetic mechanical induction. Background Technology

[0002] Live-state detection devices are typically used to inspect electrical equipment to prevent issues such as leakage. These devices require prior inspection. The operation of passive electromagnetic mechanical induction differs from traditional mechanical connections; it uses electromagnetic transmission. During this process, the electrical operation of the equipment must be guaranteed, necessitating live-state detection to prevent leakage and other problems.

[0003] However, traditional detection devices are usually operated manually, with staff holding the detection mechanism and using the detection contacts to perform live detection on the equipment. This poses safety hazards and makes detection difficult at high altitudes. Furthermore, the method of detecting one location at a time is inefficient and cannot detect multiple objects simultaneously. Therefore, this invention proposes a contact-type device for detecting the live state of equipment based on passive electromagnetic mechanical induction. Summary of the Invention

[0008] As a preferred embodiment of the present invention, the detection structure further includes a reinforcement component. The reinforcement component works in conjunction with the detection structure to enhance the support force on the fixing frame. The reinforcement component includes a fixing ring, which is fixedly connected to the hollow frame. A rotating ring is rotatably provided on the inner side of the fixing ring, and two connecting plates are fixedly provided on the outer side of the rotating ring.

[0009] In a preferred embodiment of the present invention, the fixed frame is fixedly connected to the vehicle body, one end of the threaded rod passes through the fixed frame and is fixedly connected to the output shaft of the motor, and the motor acts on the threaded rod to drive the slider to move in the vertical direction.

[0010] As a preferred technical solution of the present invention, the vehicle body is provided with a support structure on its exterior. The support structure, in conjunction with the detection structure, is used to improve the working stability of the electric push rod. The support structure includes a bottom ring and two sliding plates. Two movable tubes are rotatably connected to the outside of the bottom ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a detection structure, the device can simultaneously perform live state detection on multiple detection positions. The working angles of the two sets of detection mechanisms can be adjusted as needed via the fixing frame, or the angles of the detection mechanisms can be directly adjusted to adjust the usage angles of the corresponding two detection contacts, which greatly improves the detection efficiency of the device. At the same time, the height of the slider can be adjusted by the motor and the threaded rod, so the detection height can be adjusted as needed. 2. By setting up adjustment components in conjunction with the detection structure, it is beneficial to directly adjust the included angle between the two detection contacts corresponding to the two sets of detection mechanisms. This allows the detection contacts to be adjusted according to the size of the detected position of the passive electromagnetic mechanical induction device, making it easier for the detection contacts to make better contact with the detection position for detection. Compared with traditional fixed detection contacts, it is more flexible, has a larger detection range, and can form a straight line with the bidirectional lead screw when the device is not in use, which facilitates later storage and does not occupy the space. 3. By setting up control components in conjunction with the detection structure, it is convenient to adjust the working angle of the electric push rod as needed, which facilitates the folding and storage of the entire device later. Moreover, the working angle of the electric push rod can be modified according to the detection needs, so that the detection contact can be positioned higher to detect the required position, thereby improving the adaptability of the device. 4. By setting up reinforcement components in conjunction with the detection structure, it is beneficial to make up for the lack of stability in the connection between the fixed frame and the hollow frame. The fixed ring, rotating ring, and connecting plate, together with the fixed frame, can provide stable support, thereby enhancing its stability during operation. 5. By setting up a support structure in conjunction with the detection structure, it is beneficial to compensate for the deficiency of the detection structure's own insufficient support force. When the electric push rod extends, the support force of one end of the electric push rod gradually weakens, posing a safety hazard. The support structure can solve this safety hazard, thereby enhancing the stability and safety of the device. The sliding plate, slider three, support rod, bolts, movable tube, and bottom ring support the electric push rod one. The support components, in conjunction with the support structure, are beneficial to providing support force to slider three. The electric push rod three acts on the top plate in conjunction with slider three, so that slider three is blocked by the top plate to prevent it from sliding down during support. 6. By setting up a protective structure in conjunction with the detection structure, it is beneficial to solve the problem that the detection mechanism and detection contacts are easily damaged by external factors when the device is not in use. The connecting rod one, the multi-stage electric telescopic rod, and the connecting rod two work together to ensure that the protective cover protects the detection mechanism and the four detection contacts that form a straight line when the device is not in use, ensuring that the detection mechanism and detection contacts are not exposed.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-11 As shown, the contact-type equipment energized state detection device based on passive electromagnetic mechanical induction includes a vehicle body 1, and a detection structure 2 is provided on the outside of the vehicle body 1. The detection structure 2 includes a fixed frame 5 and a fixed bracket 14. A threaded rod 6 is rotatably mounted inside the fixed frame 5. A slider 8 is threaded onto the outside of the threaded rod 6. A shelf 9 is fixedly mounted outside the slider 8, and a base 10 is rotatably mounted through the inside of the shelf 9. An electric push rod 11 is mounted outside the base 10. A hollow frame 12 is fixedly mounted at one end of the electric push rod 11. The outside of the fixed bracket 14 is fixedly connected to the output shaft of a motor 13 via a guide rod passing through the hollow frame 12. A bidirectional lead screw 15 is rotatably mounted through the inside of the fixed bracket 14. One end of the screw 15 is fixedly connected to the output shaft of the motor 16. Two sliders 17 are threaded on the outside of the double-acting screw 15. A gantry frame 18 is fixedly mounted on the outside of the sliders 17. A motor 19 is mounted on the inside of the gantry frame 18. The output shaft of the motor 19 passes through the gantry frame 18 and is fixedly connected to the detection mechanism 20. Two detection contacts 21 are rotatably mounted on the inside of the detection mechanism 20. The motor 13 acts on the fixed frame 14 to adjust the angle of the detection mechanism 20. The motor 19 acts on the detection mechanism 20 to adjust the angle of the detection contacts 21.

[0020] The detection structure 2 enables the device to simultaneously perform live state detection on multiple detection locations. The working angles of the two sets of detection mechanisms 20 can be adjusted as needed via the fixing frame 14, or the angles of the detection mechanisms 20 can be directly adjusted to adjust the usage angles of the corresponding two detection contacts 21, greatly improving the detection efficiency of the device. At the same time, the height of the slider 8 can be adjusted by the motor 7 in conjunction with the threaded rod 6, thereby adjusting the detection height as needed.

[0021] In this embodiment, the detection structure 2 also includes two sets of adjustment components. The adjustment components work with the detection structure 2 to adjust the included angle between the two detection contacts 21. The adjustment components include an electric push rod 22 and two gears 24. The electric push rod 22 is located outside the detection mechanism 20. One end of the electric push rod 22 is fixedly connected to a serrated plate 23, and the serrated plate 23 and the two gears 24 are meshed and connected. The gears 24 are fixedly connected to the corresponding detection contacts 21.

[0022] The adjustment component, in conjunction with the detection structure 2, can directly adjust the included angle between the two detection contacts 21 corresponding to the two sets of detection mechanisms 20. This allows the detection contacts 21 to be adjusted according to the size of the detected position of the passive electromagnetic mechanical induction device, facilitating better contact between the detection contacts 21 and the detection position for detection. Compared to the traditional fixed detection contacts 21, this method is more flexible, has a larger detection range, and allows the four detection contacts 21 to be aligned in a straight line parallel to the bidirectional lead screw 15 when the device is not in use. This facilitates later storage without taking up valuable space.

[0023] In this embodiment, the detection structure 2 also includes a control component. The control component works with the detection structure 2 to control the working angle of the electric push rod 11. The control component includes a mounting plate 25 and two gears 28. The mounting plate 25 is fixedly connected to the shelf 9. A motor 26 is provided on the outside of the mounting plate 25. The output shaft of the motor 26 passes through the mounting plate 25 and is fixedly connected to a gear transmission component 27. The gear transmission component 27 and the shelf 9 are rotatably connected through the gears 28 and the base 10. The gears 28 and the gear transmission component 27 are meshed together.

[0024] The control components, in conjunction with the detection structure 2, can adjust the operating angle of the electric push rod 11 as needed, facilitating the later folding and storage of the entire device. Furthermore, the operating angle of the electric push rod 11 can be modified according to the detection requirements, allowing the detection contact 21 to be positioned higher to perform detection work on the required location, thereby improving the device's operational adaptability.

[0025] In this embodiment, the detection structure 2 also includes a reinforcement component. The reinforcement component works with the detection structure 2 to strengthen the support force on the fixing frame 14. The reinforcement component includes a fixing ring 29, which is fixedly connected to the hollow frame 12. A rotating ring 30 is rotatably provided on the inner side of the fixing ring 29, and two connecting plates 31 are fixedly provided on the outer side of the rotating ring 30. The connecting plates 31 are fixedly connected to the fixing frame 14.

[0026] The reinforcement components, together with the detection structure 2, can compensate for the lack of stability in the connection between the fixed frame 14 and the hollow frame 12. The fixed ring 29, the rotating ring 30, and the connecting plate 31, together with the fixed frame 14, can provide stable support and enhance its stability during operation.

[0027] In this embodiment, the fixed frame 5 and the vehicle body 1 are fixedly connected. One end of the threaded rod 6 passes through the fixed frame 5 and is fixedly connected to the output shaft of the motor 7. The motor 7 acts on the threaded rod 6 to drive the slider 8 to move in the vertical direction.

[0028] Motor 7 controls the rotation of threaded rod 6, allowing slider 8 to adjust the overall height of detection structure 2, facilitating the detection work of detection contact 21.

[0029] In this embodiment, a support structure 3 is provided on the outside of the vehicle body 1. The support structure 3, together with the detection structure 2, is used to improve the working stability of the electric push rod 11. The support structure 3 includes a bottom ring 32 and two sliding plates 33. Two movable tubes 34 are rotatably connected to the outside of the bottom ring 32. A slider 35 is slidably provided on the inside of the sliding plate 33. A support rod 36 is rotatably connected to one side of the slider 35. The support rod 36 and the movable tubes 34 are connected by bolts 37.

[0030] The support structure 3, together with the detection structure 2, can compensate for the deficiency of the detection structure 2's own insufficient support force. When the electric push rod 11 extends, the support force of the electric push rod 11 on one end of the component gradually weakens after the extension, which poses a safety hazard. The support structure 3 can solve this safety hazard, thereby enhancing the stability and safety of the device. The slide plate 33, the slider 35, the support rod 36, the bolt 37, together with the movable tube 34 and the bottom ring 32, support the electric push rod 11.

[0031] In this embodiment, the support structure 3 further includes a support component, which works with the support structure 3 to provide support for the slider 35. The support component includes an electric push rod 38, which is fixedly connected to the vehicle body 1. One end of the electric push rod 38 is fixedly connected to a top plate 39, and the top of the top plate 39 is flush with the bottom of the slider 35.

[0032] The support component, together with the support structure 3, can provide support force for the slider 35. The electric push rod 38 acts on the top plate 39 in conjunction with the slider 35, so that the slider 35 is blocked by the top plate 39 to prevent it from sliding down when supported.

[0033] In this embodiment, the bottom ring 32 and the electric push rod 11 are fixedly connected, the slide plate 33 and the vehicle body 1 are fixedly connected, and the slider 35 slides on the inner side of the slide plate 33 under the action of the electric push rod 38.

[0034] The electric push rod 38, together with the top plate 39, acts as a blocking and supporting element for the slider 35, preventing the slider 35 from sliding down during the supporting operation.

[0035] In this embodiment, the inner side of the movable tube 34 is provided with an internal thread, and the thread of the bolt 37 and the internal thread of the movable tube 34 are compatiblely matched.

[0036] Under the action of bolt 37, the support rod 36 and the movable tube 34 are connected, so that the support rod 36 and the movable tube 34 form a complete support unit.

[0037] In this embodiment, a protective structure 4 is provided on the outside of the fixed frame 14. The protective structure 4, together with the detection structure 2, is used to protect the detection mechanism 20 and the detection contact 21. The protective structure 4 includes two mounting frames 40 and a base plate 42. The mounting frames 40 and the fixed frame 14 are fixedly connected, and the base plate 42 and the fixed frame 14 are fixedly connected. The base plate 42 is penetrated by a bidirectional lead screw 15. A protective cover 41 is rotatably provided on the outside of the mounting frame 40. Two connecting rods 43 are rotatably provided on the outside of the base plate 42. Two multi-stage electric telescopic rods 44 are fixedly provided on the outside of the connecting rods 43. A connecting rod 45 is rotatably provided on the inside of the protective cover 41. One end of the multi-stage electric telescopic rod 44 is fixedly connected to the corresponding connecting rod 45.

[0038] The protective structure 4, in conjunction with the detection structure 2, can solve the problem that the detection mechanism 20 and the detection contact 21 are exposed to the outside when the device is not in use and are easily damaged by external factors. The connecting rod 1 43, the multi-stage electric telescopic rod 44, and the connecting rod 2 45 work together to ensure that the protective cover 41 protects the detection mechanism 20 and the four detection contacts 21 that form a straight line when the device is not in use, ensuring that the detection mechanism 20 and the detection contacts 21 are not exposed.

[0039] It should be noted that this invention is a contact-type equipment live state detection device based on passive electromagnetic mechanical induction. Before use, the device can be placed in the required location to enable it to meet the operating conditions. In the initial state, the electric push rod 11 and the top of the vehicle body 1 are perpendicular, the slider 8 is located at the top of the inner side of the fixed frame 5, and the two protective covers 41 are closed. The four detection contacts 21 are parallel to the bidirectional lead screw 15. The detection mechanism 20 and the detection contacts 21 are protected inside the two protective covers 41. The bolt 37 is not connected to the movable tube 34. At this time, the whole device is in a folded storage state. When the device is to perform testing on a passive electromagnetic mechanical induction device, the vehicle body 1 is pushed to the required location. In the initial state of the device, motor 26 is started, causing gear transmission component 27 and gear 28 to mesh and move until electric push rod 11 rotates 90 degrees and stops. At this time, electric push rod 11 is parallel to the top of the vehicle body 1. Electric push rod 38 is started, and top plate 39 pushes slider 35 upward until slider 35 moves to the predetermined position and stops. Support rod 36 is rotated by a predetermined angle until one end of support rod 36 matches the position of movable tube 34 and stops. Bolt 37 is installed in the predetermined position, so that support rod 36 and movable tube 34 are connected. At this time, electric push rod 11 is driven by electric push rod 38. The top plate 39, slide plate 33, slider 35, and support rod 36 provide support and relieve the pressure on motor 5 26. The multi-stage electric telescopic rod 44 is activated until the two protective covers 41 are rotated open to the predetermined angle and then stops. At this time, the detection mechanism 20 and the detection contact 21 are exposed. Then, the electric push rod 22 is activated to make the serrated plate 23 and gear 1 24 mesh until the corresponding two detection contacts 21 are in a parallel state and then stops. According to the position that the passive electromagnetic mechanical induction device needs to be detected, the motor 3 16 is activated to make the two sets of detection mechanisms 20 move to the predetermined position under the action of slider 2 17 and then stop so that the detection contact 21 contacts the position to be detected. The detection mechanism 20 can be activated to perform the detection work through the cooperation of the detection contact 21. In addition, the angle between the two detection contacts 21 can be adjusted as needed by the cooperation of the electric push rod 22, the sawtooth plate 23, and the gear 24, so that it can be better adjusted according to the shape and size of the detection position. The motor 13 can be started as needed to adjust the angle position of the fixing frame 14. The fixing frame 14, along with the connecting plate 31 and the rotating ring 30, moves inside the fixing ring 29, which can improve the working stability of the fixing frame 14 and thus adjust the angle position of the two sets of detection mechanisms 20. Alternatively, the motor 19 can be started to directly act on the detection mechanism 20 to rotate the detection contacts 21 and adjust the use angle of the detection contacts 21. The position of the slider 8 on the threaded rod 6 can be adjusted by motor 7 as needed, and the working angle of the electric push rod 11 can be adjusted by motor 26, so that the detection mechanism 20 can perform detection work at a higher position. Furthermore, the aforementioned testing mechanism 20 and testing contact 21 can be referenced to "tester 304 and testing head 306" in the prior art document CN119575095A. Therefore, the aforementioned testing mechanism 20 and testing contact 21 are existing technical means and will not be elaborated further.
