TECHNICAL FIELD
[0001] The utility model relates to adjustable probe type insulator detector technical field, specifically adjustable probe type insulator detector. BACKGROUND
[0002] Insulator detector is a kind of special equipment for the nondestructive testing of insulator insulation performance of transmission line and transformer substation, and it is one of the key tools for guaranteeing the safe operation of power grid by means of electrical measurement, signal analysis and other ways to determine whether there are defects such as deterioration and insulation failure of insulator, and its detection principle is mainly divided into high-voltage pulse method, leakage current method and infrared thermal imaging method, and it is mainly applied to transmission line inspection: through unmanned aerial vehicle traction or artificial tower climbing, the deterioration of suspension insulator string is detected;Transformer substation detection: off-line or live sampling inspection is carried out on post insulator and circuit breaker insulator;Insulator production quality inspection: the insulation performance of finished product insulator is detected before leaving factory to guarantee product compliance.
[0003] However, the existing part of insulator detector cannot adjust the distance of probe, so that not only its adaptability is poor, only single specification insulator can be compatible, but also probe and steel cap can not be in poor contact, and then detection data is distorted.
[0004] Therefore, the skilled in the art provides an adjustable probe type insulator detector to solve the problems raised in the above background. UTILITY MODEL CONTENTS
[0005] The utility model aims at providing an adjustable probe type insulator detector to solve the problems raised in the above background.
[0006] To achieve the above object, the utility model provides the following technical scheme:
[0007] An adjustable probe type insulator detector, comprising a fixed frame body, the inner side wall of the fixed frame body is fixedly connected with a sensor fixing frame, the outer side of the sensor fixing frame is fixedly connected with an infrared sensor, the outer surface of the fixed frame body is grooved on the upper side with a plurality of drive assembly fixing grooves, the inside of the drive assembly fixing groove is fixedly connected with a drive assembly, and the side of the drive assembly is fixedly connected with a detection probe.
[0008] As a further scheme of the utility model, the lower side of the fixed frame body is fixedly connected with a bottom support foot, and the upper side of the fixed frame body is fixedly connected with a top lifting lug.
[0009] As a further scheme of the utility model, the outer side of the fixed frame body is fixedly connected with a side control frame, and the inside of the side control frame is fixedly connected with a control module.
[0010] As a further scheme of the utility model, one side of the control module is fixedly connected with a power module, one side of the power module is fixedly connected with a wireless communication module.
[0011] As a further scheme of the utility model, the detection probe is externally sleeved with an insulating ceramic sheath, and the withstand voltage value of the insulating ceramic sheath is not less than 10 kV.
[0012] As a further scheme of the utility model, the wireless communication module is a 5G / Wi-Fi dual-mode communication module, and the wireless communication module is used for establishing the communication connection between the control module and the unmanned aerial vehicle flight control system and the ground terminal, and realizes the real-time transmission of detection data.
[0013] Compared with the prior art, the utility model has the beneficial effects that:
[0014] 1. The detection probe spacing can be adjusted by the driving assembly and other structures, so that the device can not only adapt to multiple types and specifications of insulators, but also has stronger universality. The specifications of insulators in different scenarios differ greatly, and the adjustable spacing detection probe can be flexibly adjusted according to the actual spacing of the insulator steel cap. Without replacing the special detection probe, the device can be compatible with various insulators such as suspension, pole and rod insulators in power transmission lines and substations. Compared with the fixed probe detector, the model coverage is greatly improved, the replacement cost is reduced, and the accurate fitting of the detection probe and the insulator steel cap can also be ensured, which improves the detection accuracy. In the long-term operation of the insulator, slight deviation and steel cap wear may occur. The fixed spacing detection probe is prone to incomplete contact and suspension due to matching errors, which may cause data collection distortion. The adjustable spacing detection probe can be fine-tuned by the driving assembly to ensure that the detection probe head is fully fitted with the steel cap, avoid measurement errors of insulating resistance and leakage current caused by poor contact, ensure the accuracy of detection data, reduce the defect misjudgment rate, and avoid hard contact damage to protect the insulator and the detection probe. If the fixed spacing detection probe does not match the spacing of the insulator steel cap, hard collision may occur during contact, which may scratch the surface of the insulator or damage the head of the detection probe. The adjustable spacing detection probe can be adapted and then fitted, achieving flexible contact through gentle adjustment, reducing the risk of physical damage to the insulator, prolonging the service life of the detection probe, and adapting to complex detection scenarios to improve work efficiency. In the high-altitude detection scenario of unmanned aerial vehicle traction, the pitch of the insulator string may fluctuate due to installation errors and aging deformation. The adjustable spacing detection probe can dynamically adapt to insulators with different pitches during the detection process without manual intervention to adjust the position of the equipment, and the detection time of each insulator string is shortened. The device can also adapt to narrow space detection to avoid scratching the detection probe with surrounding equipment, and can also be compatible with different detection needs to expand the function scenario. In addition to regular insulating performance detection, the adjustable spacing detection probe can be combined with different detection modes to accurately locate local defects of the insulator. The device can also be adapted to insulator production quality inspection scenarios to detect finished insulators of different batches, and improve the functional multiplicity of the equipment.
