Description

Technical Field

[0001] The invention relates to the technical field of power grid detection, and in particular to an infrared detection device based on power grid digital application. Background Art

[0002] Digital applications of power grids generally refer to applications in power grid monitoring and control. They use IoT sensor technology to collect data on the operating parameters (voltage, current, temperature, vibration, etc.) of power grid equipment (such as generators, transformers, power grid cables, etc.). These data are transmitted to the power grid control center through the communication network, so that operators can intuitively see the operating status of the equipment. For example, by installing infrared detection devices on the power grid cables, when the power grid cables are damaged, resulting in increased resistance and subsequent temperature rise, early warnings can be issued in time to avoid overheating and damage to the power grid cables.

[0003] In the prior art, when inspecting power grid cables, the inspection device is usually hung on the cable. The inspection device is generally provided with a driven roller and a detection device so that it has a walking function and a cable detection function. The detection device is generally composed of an infrared module or a visual detection module and a data transmission and processing module, which is convenient for visual inspection at work. However, the inspection device of the power grid cable in the prior art lacks a cross-line transfer mechanism and can only inspect a single power grid cable. When the remaining power grid cables need to be inspected, the workers need to manually remove the inspection device from the original power grid cable and then move it to the lower power grid cable to continue the inspection work. The above operation is time-consuming and labor-intensive and will reduce the inspection efficiency of the inspection device for the power grid cable. Summary of the invention

[0044] A section is provided at the outer end of the gear transmission member 317, on which a transmission bottom rod 325 is provided, on which an electric telescopic rod 2 326 is provided, and a top block 327 is provided at the top of the electric telescopic rod 2 326, in which a worm 328 is provided, and the worm 328 is meshed with a worm wheel 329 rotatably located in the top block 327, and a drive fixed to the top block 327 is provided at the end, and a connecting member 1 330 is fixed on the rotating shaft of the worm wheel 329, and the connecting member 1 330 is connected to the cable detection mechanism 41 by being engaged with the connecting member 2 412.

[0045] The locking component includes an electric telescopic rod 320 fixed on the arc frame 318, the extending rod on the electric telescopic rod 320 is fixedly connected to one end of the limiting plate 322, the arc frame 318 is provided with an extension shaft 323 that passes through the arc frame 318 and is fixedly connected to the gear transmission member 317, the extension shaft 323 is provided with a special-shaped limiting rod 324 that is clamped with the limiting groove on the other end of the limiting plate 322, and the bottom end of the electric telescopic rod 320 is provided with a limiting tooth block 321 that passes through the arc frame 318 and is clamped with the limiting gear ring 221.

[0046] An inner gear ring 312 is provided on the inner end surface of the gear ring body 311 , and a driving motor 1 313 is provided in the support plate 219 . The driving motor 1 313 is driven and connected to a driving gear 314 located in the support plate 219 , and the driving gear 314 meshes with the inner gear ring 312 .

[0047] Working principle of the transfer transmission mechanism 31: when the transfer transmission mechanism 31 needs to drive the cable detection mechanism 41 to detect the power grid cable 4 on the same side of the electric pole 1, the electric telescopic rod 320 is started to contract so that the limit tooth block 321 is separated from the limit gear ring 221. At this time, the limit plate 322 is driven to move upward so that the limit groove is engaged with the special-shaped limit rod 324, that is, the gear transmission member 317 cannot rotate by itself, and the relative position of the driving gear 314 and the gear ring body 311 is fixed;

[0048] Start the drive motor 1 313, and the drive motor 1 313 drives the gear ring body 311 to rotate through the meshing side of the drive gear 314 and the inner gear ring 312. When the gear ring body 311 rotates, it can drive the cable detection mechanism 41 to rotate around the electric pole 1 through the transfer transmission mechanism 31. When the cable detection mechanism 41 rotates to a predetermined position near the power grid cable 4, start the electric telescopic rod 1 320 to extend. At this time, the limit groove and the special-shaped limit rod 324 are disengaged and the limit tooth block 321 can be engaged with the limit gear ring 221. At this time, the position of the gear transmission member 317 remains unchanged, and the gear ring body 311 can continue to rotate. That is, at this time, the gear transmission member 317 is self-rotating, and the gear transmission member 317 drives the electric telescopic rod 2 326 to rotate around the gear transmission member 317 through the transmission bottom rod 325. The electric telescopic rod 2 326 drives the cable detection mechanism 41 to be sleeved outside the power grid cable 4 through the top block 327, the connecting member 1 330, and the connecting member 2 412;

[0049] When the cable detection mechanism 41 and the grid cable 4 are in a non-parallel state, the drive on the worm 328 is started to drive the worm 328 to rotate, the worm 328 drives the connecting piece 1 330 to rotate through the worm wheel 329, and the connecting piece 1 330 drives the cable detection mechanism 41 to rotate through the connecting piece 2 412, so that the cable detection mechanism 41 is completely covered outside the grid cable 4, and then the cable detection mechanism 41 can detect the grid cable 4;

[0050] When it is necessary to detect the grid cable 4 on different sides of the electric pole 1, the relative position of the gear transmission part 317 and the ring gear body 311 can be fixed, and then the electric telescopic rod 326 is started to retract, so that the height of the cable detection mechanism 41 is lower than the grid cable 4, and the ring gear body 311 is rotated to drive the cable detection mechanism 41 to pass through the grid cable 4 on one side to the grid cable 4 on the other side, and then the electric telescopic rod 326 is started to extend to the initial state, and finally the cable detection mechanism 41 is driven to move to the grid cable 4 on the other side through the transfer transmission mechanism 31. When detecting the grid cables 4 on both sides, the ring gear body 311 is driven to rotate reciprocatingly so that the transfer transmission mechanism 31 drives the cable detection mechanism 41 to reciprocate.

[0053] The detection drive mechanism 417 includes a side frame 418 fixed on the connecting frame 411, a through slot 419 is provided at the side end of the side frame 418, a sealing plate 420 is provided in the through slot 419 and is slidably arranged inside the side frame 418, an electric telescopic rod 421 is provided at the bottom of the side frame 418 on one side of the through slot 419, the top of the electric telescopic rod 421 is connected to the top of the sealing plate 420, a driving roller 422 is rotatably provided at the top of the side frame 418, and the rotating shaft of the driving roller 422 passes through the side frame 418 and the end thereof is connected to a driving motor 422 located on the side frame 418. 23. Guide blocks 424 located below the driving roller 422 are provided at both end surfaces of the side frame 418. An electric telescopic rod 425 is provided at the bottom of the side frame 418.

The power grid cable 4 is located between the driving roller 422 and the driven roller 428 and is rollingly connected to the driving roller 422 and the driven roller 428.

[0054] The working principle of the connector 1 330 and the connector 2 412: when the cable detection mechanism 41 needs to be separated from the transfer transmission mechanism 31, the cable detection mechanism 41 is started to move on the power grid cable 4. During the movement, the magnetic block 1 336 on the connector 1 330 is separated from the magnetic block 2 414 on the connector 2 412, and the power supply terminal 415 is separated from the power supply terminal 335. The connector 1 330 and the connector 2 412 slide relative to each other until they are separated. At this time, the cable detection mechanism 41 is separated from the transfer transmission mechanism 31, and the detection work can be started. Whether the cable detection mechanism 41 can maintain balance on the power grid cable 4 depends on the production, assembly and actual use debugging of each component of the cable detection mechanism 41. During debugging, a balancing block can be placed in the connecting frame 411 to keep the cable detection mechanism 41 balanced. The balancing block is a counterweight block in the prior art. The addition of the counterweight block is a routine operation of the staff in this field and is not described in detail in the present invention.

[0055] When the cable detection mechanism 41 needs to be transferred to another grid cable 4 or the cable detection mechanism 41 needs to be charged, the cable detection mechanism 41 is moved to the position of the connector 1 330 until the connector 1 330 and the connector 2 412 are connected, the cable detection mechanism 41 can be transferred and charged.

[0056] Working principle of the cable detection mechanism 41: after the side frame 418 and the side frame 418 are completely covered on the power grid cable 4, the electric telescopic rod three 421 is started to extend, and the electric telescopic rod three 421 drives the sealing plate 420 to move upward to close the through groove 419, and the electric telescopic rod four 425 is started to extend, and the electric telescopic rod four 425 slides in the slide groove 426 through the wheel frame 427 to drive the driven roller 428 to move upward. At this time, the driving roller 422 and the driven roller 428 can clamp the power grid cable 4, and the driving motor two 423 is started, and the driving motor two 423 drives the driving roller 422 to roll on the power grid cable 4. At this time, the cable detection mechanism 41 can move on the power grid cable 4, and during the process, the infrared thermal imaging detection module 430 in the top frame 429 can perform infrared thermal imaging detection on the power grid cable 4.

[0057] Specific implementation method: The present invention provides an infrared detection device based on power grid digital application. The working principle of the present invention when detecting the power grid cable 4 is as follows:

[0058] Start the transfer transmission mechanism 31 to drive the cable detection mechanism 41 to reciprocate and rotate around the utility pole 1.
