Description

Technical Field

[0001] The present invention belongs to the technical field of cable temperature measurement, and particularly relates to an on-line infrared temperature measurement device and method for cable intermediate joints in pipe shafts. Background Art

[0002] In the power system, the temperature state of cable intermediate joints is a key indicator for evaluating their operation reliability. Factors such as cable dielectric loss and joint process defects are likely to cause local temperature rise, and long-term high temperature will accelerate the deterioration of insulation performance and even lead to short-circuit faults. Therefore, implementing on-line temperature monitoring for cable intermediate joints can timely detect latent defects and effectively reduce the operation and maintenance costs of the power grid.

[0003] Currently, the following technical solutions are mainly adopted for temperature measurement of cable joints in pipe shafts: Handheld infrared temperature measurement method: Regular measurement is carried out by manually holding the device, which has defects such as a long measurement period and limited coverage, and it is difficult to meet the requirements of real-time monitoring.

[0004] Embedded sensor method: Temperature sensors are implanted inside the cable joints. Although the measurement accuracy is relatively high, the construction process requirements are extremely strict. If there are air gaps in the installation position of the sensors, it is easy to cause local electric field distortion, which will instead accelerate insulation aging.

[0005] The existing patent document (application number: 202223216565.2) discloses a cable temperature measurement device in a pipe shaft, but its structure is still a handheld device, which cannot achieve full-automatic periodic monitoring and lacks the ability of multi-dimensional space adjustment, making it difficult to adapt to the three-dimensional distribution characteristics of cable joints in complex pipe shaft environments.

[0032] The rotation mechanism 2 in this embodiment includes a rotating external gear 21, a rotating slide rail 22, a rotating motor 23, a rotating gear 24, a rotating base 25 and a rotating slider 26.

[0035] The lifting cylinder 33 drives the lifting inner rod 32 to move axially along the pipe well 9, enabling the detection host 8 to adapt to cable joints at different heights, especially suitable for complex scenarios with multi-layer cable arrangements; the guiding structure of the lifting chute 35 and the slider 34 ensures the movement rigidity and avoids sagging deformation caused by gravity.

[0036] The swing mechanism 4 in this embodiment includes a swing cross bar 41, a swing cylinder 42, a swing bracket 43, and a swing rotating shaft 44.

The angle adjustment of the detection host 8 can be realized through the provided swing mechanism 4.

[0037] The swing cylinder 42 drives the swing cross bar 41 to rotate around the swing rotating shaft 44, adjusting the vertical angle of the detection host 8, such as ±90°, which can flexibly align with the cable joints at the top or bottom of the pipe well, solving the problem that traditional fixed-angle devices are difficult to cover the vertical direction.

[0038] The telescopic mechanism 5 in this embodiment includes a telescopic sleeve 51, a telescopic rod 52, a telescopic cylinder 53, a telescopic slider 54, and a telescopic chute 55.

[0041] The adjustment motor 64 drives the adjustment gear 63 to mesh with the adjustment external gear 62, realizing fine adjustment of the horizontal angle of the detection host 8, such as ±180°, ensuring that the infrared lens is accurately aligned with the target joint and eliminating the temperature measurement deviation caused by installation errors. The modular design enables the adjustment bracket 61 to be adapted to different models of detectors.

[0042] The temperature measurement method of the online infrared temperature measurement device for the intermediate joint of the cable in the pipe well in this embodiment is as follows: The rotating gear 24 is driven to rotate by the rotating motor 23. Since the rotating gear 24 is meshed with the rotating outer gear 21, the rotating slider 26 can drive the rotating base 25 to rotate along the rotating slide rail 22, thereby realizing the circumferential movement of the detection host 8 along the pipe shaft 9; the lifting slider 34 is driven to move along the lifting slide groove 35 by the lifting cylinder 33. Since the lifting slider 34 is fixed to the lifting inner rod 32, the lifting inner rod 32 can be lifted and lowered in the lifting outer sleeve 31, thereby realizing the axial movement of the detection host 8 along the pipe shaft 9; the swing cross bar 41 is driven to move along the lifting groove 35 by the swing cylinder 42. The swing shaft 44 rotates, thereby realizing the angle adjustment of the detection host 8 in the vertical direction; the telescopic slide block 54 is driven by the telescopic cylinder 53 to move along the telescopic slide groove 55. Since the telescopic slide block 54 is fixed to the telescopic sleeve rod 52, the telescopic sleeve rod 52 can be raised and lowered in the telescopic sleeve 51, thereby realizing the radial movement of the detection host 8 along the pipe shaft 9; the adjusting gear 63 is driven to rotate by the adjusting motor 64. Since the adjusting gear 63 is meshed with the adjusting outer tooth 62, the adjusting bracket 61 can be rotated, thereby realizing the angle adjustment of the detection host 8 in the horizontal direction.

[0043] When replacing the detection host 8, the locking button 73 is pressed to make the locking slide 74 slide in the locking cavity 71, and the locking spring 75 is in a compressed state. At this time, the locking block 76 moves downward in the locking groove 78, so that the locking block 76 is disengaged from the locking groove 77, and the detection host 8 can be taken out; when installing the detection host 8, the locking rod body 72 is inserted into the locking cavity 71, and under the action of the guide surface, the locking groove 77 can be locked into the locking groove 78, thereby realizing the installation of the detection host 8.

[0044] Specifically, the online infrared temperature measuring device for the intermediate joint of the cable in the pipe shaft can realize full coverage temperature measurement of the cable joint in the pipe shaft through the rotating mechanism 2, lifting mechanism 3, swing mechanism 4, telescopic mechanism 5, and adjustment mechanism 6; according to the different requirements of temperature measurement points of different cable intermediate joints, the control strategy of the staying position of the infrared temperature measuring device on the slide rail can be studied to meet the temperature measurement requirements of different points.

[0045] The above method realizes 3D spatial full coverage temperature measurement of cable joints through circumferential, axial, radial movement and multi-angle adjustment, solving the limitations of traditional single-point or fixed path monitoring. The motion trajectory is dynamically planned according to the distribution of cable joints, and the dwell position and angle are automatically adjusted to improve the temperature measurement efficiency; multiple groups of detection tasks can be preset to meet the needs of periodic inspections. The closed-loop control of each mechanism ensures that the repeated positioning accuracy of the detection host 8 is ≤0.5mm, ensuring the comparability of multiple temperature measurement data.
