Description

Technical Field

[0001] This utility model relates to the field of power collection lines, and in particular to a power collection line fault detection device. Background Technology

[0002] With the rapid increase in electricity consumption for production and daily life, and the expansion of cable laying areas, traditional overhead circuit cables are facing more and more safety and reliability challenges. In particular, when the timing and location of short circuit faults cannot be accurately determined, the fault point is difficult to locate quickly, which affects the normal operation of the entire circuit.

[0003] Traditional overhead power cables often experience short-circuit faults during actual use due to various unforeseen physical damage, electrical defects, or weather factors. If these faults are not detected promptly and accurately, especially in large electric fields, particularly in geographically dispersed and inaccessible areas, they may cause more serious electrical fault spread, leading to greater economic losses and equipment damage. Manual inspection is not only inefficient but also has poor applicability. In current technology, drones are commonly used to inspect overhead power cables. Existing inspection equipment mainly relies on drones to inspect the power cables. However, existing inspection drones may deviate from their inspection route due to wind, resulting in inaccurate inspection results. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where inspection drones are prone to deviating from their inspection routes, and to propose a fault detection device for power lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A control platform is located at the bottom of the drone and connected to the drone;

[0008] Four connecting rods are provided at the bottom of the control platform and at the four corners of the control platform. The four connecting rods are movably connected to the control platform.

[0010] The testing institutions include:

[0011] Upper support frame, wherein the upper support frame is a semi-circular ring structure;

[0012] A testing instrument, wherein the testing instrument is disposed at one end of the upper support frame;

[0013] A fixing module is provided on the upper support frame and is adapted to the upper support frame. When the upper support frame is in contact with the circuit cable, the fixing module clamps the circuit cable.

[0014] Furthermore, landing gear is provided on both sides of the bottom of the drone, and the overall height of the landing gear is greater than the length of the connecting rod.

[0015] Furthermore, a buffer component is also provided between the drone and the control platform.

[0016] Furthermore, the testing instrument is detachably connected to the upper support frame.

[0017] Furthermore, the upper support frame is also provided with a number of rotating balls, which are movably connected to the upper support frame.

[0018] The upper support frame is also equipped with a sliding groove.

[0019] Furthermore, the fixing module includes:

[0020] The lower support frame is a semi-circular ring structure adapted to the upper support frame, and the lower support frame is movably disposed within the sliding groove;

[0021] A rack, which is adapted to the lower support frame and is fixedly disposed on one side of the lower support frame;

[0022] A driver, which is fixedly mounted on one side of the support frame;

[0025] This application improves inspection efficiency by setting up a detection mechanism on the control platform and using a drone for power, thus replacing manual inspection. Furthermore, the fixed module in the detection mechanism secures the mechanism to the electrical cables during inspection operations, solving the technical problem of drones easily deviating from the inspection route and achieving the technical effect of improving the accuracy of inspection results.

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.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0039] Reference Figures 1 to 3 As shown, this application provides a power line fault detection device, which includes a drone 1. The drone 1 is used to provide power to the entire device so that the entire device can move. It should be noted that the drone 1 is a multi-rotor drone 1, which contains at least four sets of propellers to ensure that the device has sufficient power support and improves stability.

[0040] The power line fault detection device also includes a control platform 2 connected to the UAV 1, four connecting rods 3 connected to the control platform 2, and four detection mechanisms 4 respectively set on each of the connecting rods 3.

[0041] Specifically, the control platform 2 is located at the bottom of the drone 1 and is fixedly connected to the drone 1. For example, the control platform 2 is equipped with a signal receiver and a transmitter, allowing personnel to remotely send and receive command signals. Four connecting rods 3 are located at the bottom of the control platform 2 and at its four corners. These four connecting rods 3 are movably connected to the control platform 2 via rotating shafts, meaning that the rotation of the rotating shafts can be controlled by the control platform 2, thereby causing the four connecting rods 3 to rotate at different angles. The four detection mechanisms 4 are respectively set on the four connecting rods 3 at the ends away from the end connected to the control platform 2. The four detection mechanisms 4 are fixedly connected to the four connecting rods 3, so that the detection mechanism 4 can be moved by the movement of each connecting rod 3 to fit the circuit cable with different installation directions, thereby improving the adaptability of the equipment. That is, when it is necessary to detect the fault of the power collection line, the staff can operate the drone 1 to move the detection mechanism 4 to the circuit cable to be tested, and by rotating the connecting rod 3, the detection mechanism 4 can be adapted to the circuit cable, so that the detection mechanism 4 can be set up on the circuit cable to perform the test.

[0042] The drone 1 is provided with landing gear 11 on both sides of its bottom end. The landing gear 11 is hinged to the drone 1. When the drone 1 lands, the overall height of the landing gear 11 is greater than the length of the connecting rod 3 to prevent the detection mechanism 4 from being damaged by collision with the ground when the drone 1 takes off and lands.

[0043] In some preferred embodiments, a buffer assembly 5 is also provided between the UAV 1 and the control platform 2 to reduce the impact of the vibration of the UAV 1 on the detection mechanism 4. For example, the buffer assembly 5 may be several springs or other structures with shock absorption function.

[0044] In this embodiment, for ease of explanation, the detection mechanism 4 is described as a single detection mechanism 4. The detection mechanism 4 includes an upper support frame 41, a detection instrument 42 disposed within the upper support frame 41, and a fixing module 43 disposed on the upper support frame 41. The upper support frame 41 is a semi-circular ring structure adapted to the circuit cable, so that the upper support frame 41 is in contact with the circuit cable during detection. The detection instrument 42 is disposed at one end of the upper support frame 41 near the circuit cable and is detachably connected to the upper support frame 41 to accommodate different detection instruments 42 that can be mounted on the upper support frame 41. When the upper support frame 41 is in contact with the circuit cable, faults in the circuit cable can be detected by the detection instrument 42. Specifically, the detection instrument 42 can be a detector for detecting surface defects in circuits, or a detector for measuring the conductor resistance of circuit cables, etc. The fixing module 43 is movably mounted on the upper support frame 41 and is adapted to the upper support frame 41. When the upper support frame 41 is in contact with the circuit cable, the fixing module 43 can clamp the circuit cable to prevent the detection mechanism 4 from detaching during the detection of the circuit cable due to the influence of factors such as wind force on the UAV 1, thereby affecting the detection results and accuracy.

[0045] In some preferred embodiments, the upper support frame 41 is further provided with a plurality of rotating balls 411. Specifically, the upper support frame 41 has a plurality of arc-shaped grooves at one end near the circuit cable, and the plurality of rotating balls 411 are movably engaged with the arc-shaped grooves, so that they are movably disposed within the upper support frame 41. For example, the diameter of the opening of the arc-shaped groove is smaller than the maximum diameter of the rotating balls 411, so that the balls can rotate within the arc-shaped grooves and will not fall out of the groove openings, thereby reducing the frictional resistance between the upper support frame 41 and the circuit cable when the upper support frame 41 moves.

[0046] In this embodiment, the fixing module 43 includes a lower support frame 431, a rack 432 disposed on the lower support frame 431, a driver (not shown) disposed on the upper support frame 41, and a gear 433 connected to the driver. Specifically, the lower support frame 431 is a semi-circular ring structure adapted to the upper support frame 41. The upper support frame 41 has a semi-circular groove 412 for accommodating the lower support frame 431, allowing the lower support frame 431 to be movably disposed within the groove 412. The rack 432 is adapted to the lower support frame 431 and is fixedly disposed on one side of the lower support frame 431; that is, the rack 432 is an arc-shaped structure adapted to the lower support frame 431 to fit against it. The driver is fixedly disposed on one side of the support frame. For example, the driver is a DC motor, which consists of a stator, rotor, output shaft, and other components. Starting the motor causes the output shaft to rotate. The gear 433 is fixedly connected to the output shaft of the driver, and the gear 433 meshes with the rack 432. In this embodiment, when the upper support frame 41 is in contact with the circuit cable, the driver is activated to drive the gear 433 to rotate. With the cooperation of the gear 433 and the rack 432, the lower support frame 431 can slide out from the arc-shaped slide groove 412 and cooperate with the upper support frame 41 to form a ring, thereby enclosing the circuit cable. This allows the detection mechanism 4 to be completely fitted onto the circuit cable, thus preventing the detection mechanism 4 from detaching from the circuit cable during detection.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
