Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, and more specifically, to a tensile sensor device for monitoring equivalent icing of power transmission lines. Background Technology

[0002] In the field of transmission line icing monitoring, traditional tensile testing devices typically need to be directly connected in series with conductors or insulator strings. Installation requires the dismantling of existing line components (such as insulator fittings), leading to complex construction and prolonged power outages. Existing sensors are mostly fixed with bolts or welding, requiring personnel to work at heights for extended periods, posing risks of falls and potential misoperation. Furthermore, disassembly and maintenance necessitate a power outage, affecting grid stability. For multi-tower monitoring scenarios, repeated installation is inefficient, and traditional sensors are difficult to adapt to different tower structures. Utility Model Content

[0003] Therefore, this utility model provides a tension sensor device for monitoring equivalent icing on power transmission lines, making the installation and use of the tension sensor device more convenient.

[0004] To address the aforementioned problems, this utility model provides a tension sensor device for monitoring equivalent icing on transmission lines, comprising: a tension detection body, wherein a tension detector is disposed within the tension detection body; a fixing component, one end of which is connected to the tension detection body and the other end of which is connected to the transmission line tower; and a gripping component, which is disposed within the tension detection body and is capable of gripping and fixing an insulator on the transmission line; wherein, after the gripping component grips and fixes the insulator, the tension detector detects the force on the gripping component, i.e., the force on the transmission line, in real time.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: By directly locking the insulator with the gripping component (instead of connecting it in series with the line), disassembly-free installation is achieved, significantly reducing the risks of high-altitude operations and power outage time; the separate design of the tension detection body and the fixing component allows the device to be quickly attached to the line tower, while the adaptive fixing method of the gripping component avoids modification of the insulator structure, significantly improving installation convenience; real-time detection of stress changes on the transmission line provides direct data support for calculating icing thickness, solving the problems of complex installation and poor applicability of traditional sensors, and is especially suitable for multi-node distributed monitoring scenarios.

[0006] In one embodiment of this utility model, the gripping component includes: a connecting body, which is connected to a tensile detection body; multiple gripping parts, which are rotatably disposed on the connecting body; and a control unit, which is disposed on the connecting body and is used to control the gripping actions of the multiple gripping parts.

[0007] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the control unit centrally drives multiple gripping units, avoiding manual adjustment of each one, and improving gripping efficiency and consistency; the split gripping design adapts to insulators of different sizes, enhancing the versatility of the device, while the rotating structure releases the installation angle limitation, reducing the dependence on operational precision, and maintaining stable gripping even in strong wind and vibration environments.

[0008] In one embodiment of this utility model, the connecting body is a shaft with an axis. Each gripping part further includes: a first rotating member connected to the connecting body; and a second rotating member bent relative to the first rotating member, with the bend facing the axis.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the shaft axis provides a gripping reference, enabling the bent second rotating component to form a centripetal clamping force, thereby enhancing the wrapping of the insulator; the bending linkage design of the first and second rotating components transforms the linear gripping action into a radial locking force, preventing the insulator from slipping laterally.

[0010] In one embodiment of this utility model, the second rotating member is provided with a mating part, which is used to mate with the insulator so that the insulator is pressed and fixed by the second rotating member.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: the mating part actively presses against the surface of the insulator, forming a mechanical interlock rather than simply supporting it, preventing the insulator from detaching instantaneously during wind vibration or ice shedding; the pressing force is coordinated with the line tension, ensuring that the force path is directly transmitted to the sensor, improving the accuracy of the measurement; the forced fit between the mating part and the curved surface of the insulator reduces fretting wear on the contact surface and extends the service life of the device.

[0012] In one embodiment of this utility model, the mating part is an arc-shaped groove, the shape of which is adapted to the edge shape of the insulator.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: the curved groove matches the curved surface of the insulator edge, maximizing the contact area, dispersing local stress, and preventing crushing of the insulator glaze; the self-centering characteristic of the groove simplifies the installation and positioning process, and can still effectively cover even if there are installation deviations; the curved guide structure guides the insulator to slide into the predetermined position, reducing the difficulty of high-altitude precision operations and improving the success rate of installation on the first attempt.

[0014] In one embodiment of this utility model, the connecting body is provided with a clearance part, which is used to avoid the transmission line, so that multiple gripping parts can grip the insulator.

[0015] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the clearance section provides passage space for the conductor, eliminating the need to move the line position during installation and preventing the risk of conductor bending and damage; the open structure allows the gripping component to be inserted laterally into the insulator, realizing "side-mounted" quick assembly and solving the limitation that traditional sensors must be connected vertically in series; the clearance design is compatible with conductor arrangements with different split spacings, expanding the application scenarios of the device.

[0016] In one embodiment of this utility model, the tension sensor device for monitoring equivalent icing of transmission lines further includes: a solar panel, which is disposed on the tension detection body and is used to store electricity to supply the tension detector and the gripping component.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the solar modules achieve energy self-sufficiency, eliminating the cost of field wiring and the risk of lightning strikes; the integrated power supply system ensures long-term uninterrupted operation of the device, especially suitable for unattended high-altitude and frigid areas; the power supply covers the driving energy consumption of the grabbing components, supports remote control of grabbing status adjustment, and avoids monitoring interruptions caused by battery depletion.

[0018] In one embodiment of this utility model, the tension sensor device for monitoring equivalent icing of transmission lines further includes: an output unit, which is located on the tension detection body and is used to supply external connections to read tension detector data.

[0019] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the output unit provides a standardized data interface, compatible with handheld terminals or drones for wireless reading, replacing manual meter reading; real-time data local direct reading function, key information can still be obtained on-site when communication is interrupted; multi-protocol interface design adapts to different monitoring platforms, avoids data silos, and improves system integration efficiency.

[0020] In one embodiment of this utility model, the fixing component includes: a connector that connects to the tensile testing body; and a fixing member that is detachably connected to the connector and is used to connect to the line tower.

[0021] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: detachable fasteners enable modular connection between the device and the tower without welding or drilling, protecting the structural integrity of the tower; the split design facilitates the individual replacement of damaged parts, reducing maintenance costs; and the quick separation function of connectors and fasteners supports flexible allocation and reuse of the device between towers.

[0022] In one embodiment of this utility model, the fastener is hook-shaped.

[0023] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the hook structure uses gravity self-locking characteristics to hang tower materials, and only one hand is needed to push it during installation, which greatly reduces the intensity of high-altitude operations; the threadless design eliminates the problem of rust and jamming, and is suitable for humid and salt spray environments; the opening direction of the hook body is adjustable, which is compatible with different tower types such as angle steel towers and steel pipe towers, and improves the flexibility of equipment deployment.

[0024] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0025] (1) By directly locking the insulator with the gripping component (instead of connecting it in series with the line), the installation can be carried out without disassembly, which greatly reduces the risk of high-altitude operation and power outage time; the separate design of the tensile detection body and the fixing component allows the device to be quickly attached to the line tower, while the adaptive fixing method of the gripping component avoids the modification of the insulator structure, which significantly improves the ease of installation; real-time detection of the stress change of the transmission line provides direct data support for the calculation of ice thickness, which solves the problems of complex installation and poor applicability of traditional sensors, and is especially suitable for multi-node distributed monitoring scenarios;

[0026] (2) The control unit centrally drives multiple gripping units, avoiding manual adjustment of each one, and improving gripping efficiency and consistency; the split gripping design adapts to insulators of different sizes, enhancing the versatility of the device, while the rotating structure releases the installation angle limitation, reducing the dependence on operating accuracy, and maintaining stable gripping even in strong wind and vibration environments;

[0027] (3) The clearance section provides passage space for the conductor, so there is no need to move the line position during installation, eliminating the risk of conductor bending and damage; the open structure allows the grabbing component to be inserted into the insulator laterally, realizing "side-mounted" quick assembly, solving the limitation that traditional sensors must be connected vertically in series; the clearance design is compatible with conductor layouts with different split spacing, expanding the application scenarios of the device.
