Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power inspection technology, specifically relating to a power fault inspection device based on visual perception. Background Technology
[0002] To maintain neatness when wiring through doors, cables at bends are usually bundled together. Therefore, when the reserved cable length is fixed, the opening of the cabinet door during maintenance or assembly makes the internal insulation layer more susceptible to damage, ultimately leading to a decrease in insulation resistance and an abnormal increase in cable temperature. When the cabinet door is open, the overall heat dissipation surface increases. As a result, the fixed placement points of traditional temperature sensors cannot accurately obtain the temperature rise threshold after the cabinet door is opened, which can easily lead to misjudgment by the temperature sensor and make the fault diagnosis less accurate. Utility Model Content
[0003] This invention provides a power fault detection device based on visual perception to solve the problems mentioned in the background art.
[0004] This utility model provides the following technical solution: a power fault inspection device based on visual perception, including an in-cabinet jumper, a temperature sensor, and a thermal imaging probe. One end of the in-cabinet jumper is fixedly connected to an in-cabinet connecting lug, and a sliding fitting assembly is slidably connected to one side of the in-cabinet jumper. The sliding fitting assembly includes a metal connecting rib, a door panel connecting lug, and a movable column. One end of the metal connecting rib is fixedly connected to the door panel connecting lug, and the other end of the metal connecting rib is fixedly connected to the movable column. The movable column is slidably connected to the in-cabinet jumper. The in-cabinet jumper has an embedded slot, and the thermal imaging probe is slidably connected to the embedded slot. A pressure sensing module is fixedly connected to the inside of the embedded slot, and the pressure sensing module is used to sense whether the movable column is in a sliding unfolded state.
[0005] The thermal imaging probe is fixedly connected to the outside of the metal connecting rib, and the thermal imaging probe is located in the middle of the metal connecting rib.
[0006] The cabinet has a signal transmission module fixedly connected to the top of the jumper, and the temperature sensor and the thermal imaging probe are both connected to an external power monitoring terminal through the signal transmission module.
[0007] The cable crossover device inside the cabinet is provided with a sliding limiting groove and an arc-shaped guide groove. The arc-shaped guide groove is located at the tail of the sliding limiting groove, and the movable column is slidably connected to the inner side of the sliding limiting groove.
[0008] The sliding limiting groove and the inner side of the arc-shaped guide groove are both provided with traction ropes. One end of the traction rope is fixedly connected to the inner wall of the arc-shaped guide groove, and the other end of the traction rope is fixedly connected to the movable column.
[0009] An extension spring is fixedly connected to one side of the inner wall of the sliding limiting groove. One end of the extension spring is fixedly connected to the pressure sensing module, and the pressure sensing module is signal-connected to the thermal imaging probe.
[0010] The beneficial effects of this utility model are as follows: The power cabinet is fixed to the cabinet body via internal connecting lugs, and the door panel is fixed to the cabinet door via door connecting lugs. When the cabinet is closed, the pressure sensing module is not subjected to pressure signals from the movable column. The temperature sensor serves as the temperature detection end for the cable crossing section. When the cabinet door is opened, the movable column slides along the inner side of the sliding limit groove under the traction of the metal connecting rib, triggering a response signal from the pressure sensing module. This pressure sensing module drives the thermal imaging probe to open, simultaneously causing the thermal imaging probe to detach along the inner side of the embedded slot and be conveyed to the outside via the metal connecting rib. This allows the thermal imaging probe to be positioned on the reference surface of the cable crossing section between the cabinet door and the cabinet body after the cabinet door is opened. Furthermore, by switching the thermal imaging image acquisition method after the power cabinet door is opened, abnormal temperature rise detection of the cable crossing section can be achieved. This reduces the error in abnormal temperature rise detection and eliminates the need for the thermal imaging probe to be used in a constantly open state, thereby improving its service life.

[0017] Please see Figures 1-4 This utility model provides the following technical solution: a power fault inspection device based on visual perception, including a cabinet jumper 1, a temperature sensor 2, and a thermal imaging probe 3. One end of the cabinet jumper 1 is fixedly connected to a cabinet connecting lug 11, and one side of the cabinet jumper 1 is slidably connected to an opening and closing fitting assembly 4. The opening and closing fitting assembly 4 includes a metal connecting rib 41, a door panel connecting lug 42, and a movable column 43. One end of the metal connecting rib 41 is fixedly connected to the door panel connecting lug 42, and the other end of the metal connecting rib 41 is fixedly connected to the movable column 43. The movable column 43 is slidably connected to the cabinet jumper 1. The cabinet jumper 1 has an embedded slot 12, and the thermal imaging probe 3 is slidably connected to the embedded slot 12. A pressure sensing module 5 is fixedly connected to the inside of the embedded slot 12. The pressure sensing module 5 is used to sense whether the movable column 43 is in a sliding unfolded state.
[0018] In this embodiment, the internal connecting lug 11 is fixed to the power cabinet body with screws, and the door panel connecting lug 42 is fixed to the cabinet door. After fixing, when the cabinet body and the internal part of the cabinet are in a closed state, the pressure sensing module 5 is not subjected to the pressure signal of the movable column 43. The temperature sensor 2 is used as the temperature detection end of the cable crossing part. That is, after the temperature sensor 2 senses that the ambient temperature exceeds the set threshold, it sends the signal to the external power monitoring end through the signal transmission module 21.
[0019] In this embodiment, a signal transmission module 21 is fixedly connected to the top of the jumper 1 inside the cabinet. The temperature sensor 2 and the thermal imaging probe 3 are both connected to the external power monitoring terminal through the signal transmission module 21.
[0020] In this embodiment, the thermal imaging probe 3 is fixedly connected to the outside of the metal connecting rib 41, and the thermal imaging probe 3 is located in the middle of the metal connecting rib 41.
[0021] To ensure that the thermal imaging probe 3 can be switched to the detection end when the cabinet door is opened, this utility model, when the cabinet door is opened, the door panel connecting lug 42 on one side of the cabinet door moves with the cabinet door, the movable column 43 is pulled by the metal connecting rib 41 and slides along the inner side of the sliding limit groove 121, triggering the response signal of the pressure sensing module 5. The pressure sensing module 5 drives the thermal imaging probe 3 to open, and at the same time, the thermal imaging probe 3 is disengaged along the inner side of the embedded slot 12 and is carried to the outside by the metal connecting rib 41, so that after the cabinet door is opened, the thermal imaging probe 3 is placed on the reference surface of the cross-cable section between the cabinet door and the cabinet body. Thus, after the power cabinet door is opened, the thermal imaging image acquisition method is switched to realize the detection of abnormal temperature rise of the cross-cable section.
[0022] The cable crossover 1 inside the cabinet has a sliding limit groove 121 and an arc-shaped guide groove 122. The arc-shaped guide groove 122 is located at the tail of the sliding limit groove 121, and the movable column 43 is slidably connected to the inner side of the sliding limit groove 121.
[0023] Both the sliding limit groove 121 and the arc-shaped guide groove 122 are equipped with traction ropes 13. One end of the traction rope 13 is fixedly connected to the inner wall of the arc-shaped guide groove 122, and the other end of the traction rope 13 is fixedly connected to the movable column 43.
[0024] In this embodiment, when the cabinet door is closed again, the movable column 43 moves along the embedded slot 12 towards the arc-shaped guide groove 122. At this time, the traction rope 13 retracts until the thermal imaging probe 3 enters the inner side of the embedded slot 12. Then, the movable column 43 moves away from the contact end of the pressure sensing module 5, thereby causing the pressure sensing module 5 to release the start control of the thermal imaging probe 3. That is, in the closed state of the cabinet door, temperature detection is achieved only through the temperature sensor 2. The thermal imaging probe 3 sends the thermal imaging image to the power monitoring terminal for analysis, which is a well-known technical principle in the field. Therefore, this utility model will not elaborate on this part of the working principle.
[0025] An extension spring 51 is fixedly connected to one side of the inner wall of the sliding limit groove 121. One end of the extension spring 51 is fixedly connected to the pressure sensing module 5, and the pressure sensing module 5 is connected to the thermal imaging probe 3.
[0026] In this embodiment, to prevent the pressure sensing module 5 from failing to receive the contact pressure after the movable column 43 slides when the cabinet door is in a half-open state, an extension spring 51 is set so that the pressure sensing module 5 is initially located in the middle position of the embedded slot 12. That is, after the cabinet door opens and the movable column 43 slides, it can directly contact the pressure sensing module 5 and trigger the sensing signal of the pressure sensing module 5. Furthermore, when the cabinet door is fully opened, the extension spring 51 can be compressed by the movable column 43 and can directly retract along the inner side of the embedded slot 12 without affecting the normal opening of the cabinet door.
[0027] The working principle and usage process of this utility model are as follows: The cabinet is fixed to the power cabinet body by the internal connecting lug 11, and the door panel connecting lug 42 is fixed to the cabinet door. When the cabinet body is closed, the pressure sensing module 5 is not subjected to the pressure signal of the movable column 43. The temperature sensor 2 is used as the temperature detection end of the cross-wound cable. When the cabinet door is opened, the movable column 43 slides along the inner side of the sliding limit groove 121 by the traction of the metal connecting rib 41, and triggers the response signal of the pressure sensing module 5. The pressure sensing module 5 drives the thermal imaging probe 3 to open, and at the same time, the thermal imaging probe 3 is disengaged along the inner side of the embedded slot 12 and is carried to the outside by the metal connecting rib 41. After the cabinet door is opened, the thermal imaging probe 3 is placed on the reference surface of the cross-wound cable part between the cabinet door and the cabinet body. Then, after the power cabinet door is opened, the thermal imaging probe 3 is switched to realize the abnormal temperature rise detection of the cross-wound cable part by thermal imaging image acquisition.
