Description

Technical Field

[0001] This utility model relates to the field of measurement technology for power transmission line inspection, and in particular to a device for measuring the thickness of ice accretion on power transmission lines. Background Technology

[0002] Transmission lines are a crucial component of the power grid, and their stable operation directly impacts the reliability of power supply. In winter or in low-temperature, high-humidity environments, transmission lines are prone to icing. Icing significantly increases conductor weight and wind load cross-sectional area, and in severe cases, can lead to major accidents such as conductor breakage and tower collapse. Therefore, accurate and real-time monitoring and measurement of icing thickness on transmission lines is a key technical means to ensure the safe operation of the power grid.

[0003] Existing devices for measuring icing thickness on power transmission lines typically employ mechanical or optical sensors installed on the lines. However, since most power transmission lines are located at high altitudes and carry high voltage, the installation and maintenance of these monitoring devices must be carried out at height. Traditional fixing methods, such as bolt fastening or complex mechanical connections, require operators to spend considerable time on precise positioning and tightening operations. This not only significantly increases the time and manpower costs of working at heights but also substantially raises the safety risks faced by workers. Furthermore, some measuring devices use rigid, locked clamping mechanisms to secure the conductors for stable installation. This rigid fixing method can easily cause localized stress concentration and wear on the conductor at the clamping point when the conductor is subjected to wind vibrations or undergoes minor displacement due to thermal expansion and contraction. Over time, this can affect the mechanical life and safety of the conductor. Designing a structure that can ensure the rapid and safe installation of the measuring device on high-altitude lines while also providing flexible and stable clamping of the conductor is a critical problem that urgently needs to be solved in this field.

[0004] Therefore, this utility model proposes a device for measuring the ice thickness of transmission lines during inspection, in order to solve the shortcomings of existing measuring devices, such as long installation time, high operational risks, and the fact that rigid clamping structures are prone to damaging the lines. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a transmission line inspection ice thickness measuring device, which aims to improve the existing technology of transmission line inspection ice thickness measuring devices, which have problems such as complicated installation process, time-consuming, high risk of high-altitude operation, and their clamping structure is mostly rigid and fixed, which is easy to damage the line body during vibration or thermal expansion and contraction.

[0006] To achieve the above objectives, this utility model provides a power transmission line inspection ice thickness measuring device, comprising: a line, an upper shell, a lower shell, a camera, and a sensor; the device also includes a clamping assembly and an installation assembly.

[0007] The lower shell is detachably connected to the upper shell, the camera is mounted on the upper shell, and the sensor is mounted on either the upper shell or the lower shell.

[0008] The clamping assembly is housed inside the upper and lower housings and is used to elastically clamp the circuit, and the mounting assembly is used to connect the upper and lower housings.

[0009] The clamping assembly includes a support plate, a first clamping block, a second clamping block, a fixing rod, and a first spring. The first clamping block and the second clamping block are disposed on the support plate, and the fixing rod is fixedly connected to the support plate. The first clamping block and the second clamping block are both rotatably connected to the fixing rod, and the first spring is connected between the side wall of the first clamping block and the side wall of the support plate.

[0010] Preferably, the mounting assembly is used to lock the upper shell and the lower shell together. The device further includes an upper connecting plate and a lower connecting plate, the upper connecting plate being fixedly connected to the side wall of the upper shell and the lower connecting plate being fixedly connected to the upper part of the lower shell.

[0011] Preferably, both the upper connecting plate and the lower connecting plate are provided with sliding grooves. The mounting assembly includes a housing and a plug rod. The housing is fixed to the upper connecting plate, and the plug rod is slidably installed inside the housing and can slide through the sliding groove.

[0012] Preferably, the mounting assembly further includes a torsion block and a limiting rod, the torsion block being connected to the top of the insertion rod and the limiting rod being fixedly connected to the bottom of the insertion rod, and the device further includes a groove formed on the lower connecting plate and adapted to the limiting rod.

[0013] Preferably, the mounting assembly further includes a second spring connected between the inner wall of the housing and the side wall of the insertion rod.

[0014] Preferably, the first clamp and the second clamp are rotatably clamped to the line.

[0015] Preferably, the first spring is a memory spring.

[0016] Preferably, the camera is used to capture high-definition images, and the sensor is used to collect data in real time. The ice thickness is calculated by the coordinated use of the high-definition images captured by the camera and the real-time data collected by the sensor.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting up an installation component, the insertion rod slides inside the outer shell and passes through the slide groove. The rotating torsion block drives the limiting rod at the bottom of the insertion rod to be engaged in the groove of the lower connecting plate, and the elastic force of the second spring is used to tighten it. This solves the problems of complex installation process, time-consuming operation, high operation difficulty and high risk of high-altitude operation when the measuring device is installed on high-altitude lines in the prior art. It achieves the effects of fast installation, simple operation, stable and reliable locking, greatly shortening the high-altitude operation time and improving the operation safety.

[0018] 2. This utility model, by setting up a clamping component, uses a first spring to apply continuous elastic pressure to the rotatable first and second clamping blocks, causing them to rotate and clamp the line. This solves the problems in the prior art where clamping devices are mostly rigidly fixed, which easily cause wear and damage to the line body, and are prone to loosening and affecting measurement stability when the line vibrates or expands and contracts due to thermal expansion and contraction. It achieves the effects of elastic clamping of the line, adaptive fitting, protection of the line from damage, vibration resistance, stable clamping, and ensuring long-term stable operation of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 This utility model provides a device for measuring the ice thickness of transmission lines during inspection. It aims to solve the problems in the prior art where the fixing method of the measuring device is complicated and time-consuming when installed on high-altitude lines, and the rigid clamping structure is prone to damage to the line due to vibration or thermal expansion and contraction.

[0023] Specifically, the system includes an upper shell 2 and a lower shell 3 detachably connected below the upper shell 2. The upper shell 2 and the lower shell 3 are fastened together to form a housing structure for accommodating internal components and covering the circuit 1. A camera 5 is mounted on the outer wall of the upper shell 2, with its lens facing the circuit 1 to capture high-definition images of the circuit 1 under icing conditions. Simultaneously, a sensor 9 is mounted on either the upper shell 2 or the lower shell 3, with its probe pointed at the circuit 1 to collect data such as distance in real time. The images captured by the camera 5 and the data collected by the sensor 9 are processed collaboratively in an internal processing unit to determine the precise icing thickness.

[0024] To achieve rapid docking and secure locking of the upper shell 2 and lower shell 3 in high-altitude environments, the device is equipped with an installation assembly 8. An upper connecting plate 6 is fixedly connected to the side wall of the upper shell 2, and a lower connecting plate 7 is fixedly connected to the corresponding position on the upper part of the lower shell 3. The upper connecting plate 6 and lower connecting plate 7 are aligned and fitted together when the device is closed. Both the upper connecting plate 6 and lower connecting plate 7 have corresponding sliding grooves 806. The installation assembly 8 mainly consists of a shell 803, a plug rod 802, a torsion block 801, a limiting rod 805, and a second spring 804. The shell 803 is fixed to the top surface of the upper connecting plate 6 and is located above the sliding groove 806. The plug rod 802 is slidably installed in the internal cavity of the shell 803. The diameter of the plug rod 802 is smaller than the width of the sliding groove 806, allowing the plug rod 802 to pass axially downwards through the shell 803 and enter the sliding grooves 806 of the upper connecting plate 6 and the lower connecting plate 7.

[0025] The top of the insertion rod 802 extends out of the outer shell 803 and is fixedly connected to a torsion block 801. The torsion block 801 serves as a force-applying component for manual operation, facilitating rotation by the operator. A limit rod 805 is fixedly connected to the bottom of the insertion rod 802, and the limit rod 805 is horizontally positioned. The bottom of the lower connecting plate 7 has a groove 807 at the end of the slide groove 806, which matches the shape of the limit rod 805. A second spring 804 connects the inner wall of the outer shell 803 and the side wall of the insertion rod 802. During installation, the upper connecting plate 6 of the upper shell 2 is aligned with the lower connecting plate 7 of the lower shell 3. The insertion rod 802 inside the outer shell 803 is forced downward through the slide groove 806. At this time, the second spring 804 connected to the insertion rod 802 is stretched and accumulates elastic force. Then, the torsion block 801 is rotated ninety degrees, causing the insertion rod 802 and the bottom limit rod 805 to rotate synchronously. When the limiting rod 805 rotates to the angle corresponding to the groove 807 at the bottom of the lower connecting plate 7, under the rebound force of the second spring 804, the limiting rod 805 is pulled upward and tightly locked into the groove 807, thereby locking the upper connecting plate 6 and the lower connecting plate 7 tightly, ensuring the stability of the installation and greatly reducing the time spent working at height.

[0026] To achieve flexible protection and reliable clamping of line 1, clamping assembly 4 is housed inside the upper shell 2 and lower shell 3. Clamping assembly 4 includes a support plate 401, which is fixedly installed inside the shell. A vertical fixing rod 404 is fixedly connected to the support plate 401. First clamping block 402 and second clamping block 403 are both rotatably connected to the fixing rod 404 via a revolute joint, and are arranged opposite each other with the fixing rod 404 as the axis, forming an openable clamping space. A first spring 405 connects the side wall of the first clamping block 402 to the side wall of the support plate 401. The first spring 405 is preferably a memory alloy material, possessing excellent fatigue resistance and a stable elastic modulus.

[0027] When line 1 is inserted into the upper shell 2 and lower shell 3, line 1 presses against the inner surfaces of the first clamping block 402 and the second clamping block 403. Under the action of force, the first clamping block 402 and the second clamping block 403 deflect around the fixing rod 404, opening to accommodate the diameter of line 1. At the same time, the deflection action of the first clamping block 402 compresses or stretches the first spring 405. The reaction force generated by the first spring 405 continues to act on the first clamping block 402, thereby driving the second clamping block 403 to tightly adhere to the surface of line 1, achieving elastic clamping of line 1. This elastic clamping method can not only adapt to lines 1 of different thicknesses, but also provide buffering when line 1 experiences wind-induced vibration or thermal expansion and contraction, avoiding wear or cutting damage to line 1 caused by rigid contact. The entire device achieves efficient, safe, and accurate monitoring of transmission line icing through the quick locking of the mounting component 8 and the elastic fixation of the clamping component 4.

[0028] Working principle: When using this device, firstly, the upper shell 2 and lower shell 3 with camera 5 are installed and locked by the mounting component 8. Then, the wire 1 is elastically clamped by the clamping component 4 inside. Subsequently, with the real-time data collection of sensor 9 and the high-definition image captured by camera 5, the ice thickness is calculated by combining the wire parameters. During installation, align the upper connecting plate 6 fixed to the side wall of the upper shell 2 with the lower connecting plate 7 fixed to the upper shell 3, so that the insert rod 802 fixed inside the outer shell 803 on the side wall of the upper connecting plate 6 slides into the sliding groove 806 opened by the two connecting plates. At this time, the second spring 804, which is fixed inside the outer shell 803 at one end and fixed to the side wall of the insert rod 802 at the other end, is stretched by force. Then rotate the torsion block 801 at the top of the insert rod 802 ninety degrees so that the limiting rod 805 at the bottom of the insert rod 802 is inserted into the groove 807 at the bottom of the lower connecting plate 7, ensuring a stable installation and reducing the time spent working at height. When clamping line 1, line 1 is inserted into the upper shell 2 and lower shell 3. Under the action of force, the first clamping block 402 and the second clamping block 403, which are fixed on the side wall of the fixing rod 404 fixed on the support plate 401, are deflected. At the same time, the memory spring 405, which is fixed at one end to the side wall of the first clamping block 402 and at the other end to the side wall of the support plate 401, is compressed by force, and line 1 is elastically clamped.
