Abstract
Description
Technical Field
[0001] The present invention relates to the field of electrical testing, and in particular to an electrical testing device for an unmanned aerial vehicle. Background Art
[0002] To ensure the safe and stable operation of transmission lines, regular outages are essential. Before conducting these outages, verifying the status of each phase of the outage line to ensure it has been properly de-energized is a crucial step. Next, ground wires must be installed on each phase conductor to prevent the risk of accidentally energizing the line.
[0003] In the past, we relied on traditional electrical testing methods, requiring operators to climb towers, reach the workstations on each phase, and, while maintaining a safe distance from the transmission lines, use a tester that matches the voltage level of the line being tested. However, when working with high-voltage lines of 220kV and above, the insulated operating rods required for testing often exceed three meters in length, making them prone to bending and compromising the accuracy and safety of testing. Furthermore, traditional testing methods also present numerous issues, including poor safety, low efficiency, and excessive labor intensity. Summary of the Invention
[0004] The purpose of the present invention is to provide an unmanned aerial vehicle electrical testing device to solve the problem of manual electrical testing and achieve the effect of no need for personnel to climb the tower during the entire electrical testing process.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an unmanned aerial vehicle electrical testing device, including an electrical testing bracket and an electrical tester, the electrical testing bracket includes a bracket body and an installation space surrounded by the bracket body, the bottom end of the installation space is provided with an opening for the entry and exit of wires, the electrical tester is placed in the installation space, the electrical tester includes a connecting end and an electrical testing end, the connecting end is fixedly installed on the bracket body, and the electrical testing end is open toward the bottom end.
[0006] After adopting the above technical solution, the present invention has the following advantages: the bracket body encloses an installation space with an open bottom end, the electroscope is placed in the installation space, and the connection end of the electroscope is fixedly connected to the bracket body. The electroscope's electroscope end is arranged toward the bottom end opening of the bracket body and is used to contact the wire to test the wire's charged state. When the drone carrying the electroscope flies to the wire to be tested, the electroscope contacts the wire through the electroscope end to perform the electroscope operation. This design greatly shortens the time required for electroscope testing and improves the efficiency of electroscope testing. In addition, the electroscope is fixedly installed on the bracket body and can maintain a stable electroscope state. The problem of inaccurate electroscope testing due to improper operation is avoided. At the same time, the direct contact between the electroscope end and the wire also ensures the accuracy of the electroscope testing results. The drone electroscope testing method also avoids the high-risk operation of workers directly contacting the wire to perform electroscope testing. By remotely controlling the drone for electroscope testing, the safety risks during the operation can be significantly reduced.
[0007] Furthermore, the connecting end is fixedly mounted on the inner top wall of the bracket body.
[0008] Furthermore, the electrical test bracket also includes a fixing block, which is installed on the electrical test end of the tester. The fixing block is provided with a through hole for the electrical test end to pass through. The height of the fixing block is smaller than the height of the electrical test end. The electrical test end passes through the through hole so that the electrical test end passes through. The fixing block is fixed to the bracket body.
[0009] Using the above-mentioned technical solution, the fixed block is installed on the testing end of the electroscope and is provided with a through hole for the testing end to pass through. The height of the fixed block is smaller than the height of the testing end, so that the testing end can pass through the through hole and partially extend out of the fixed block. The fixed block is also fixed to the bracket body, ensuring that the testing end of the electroscope can be stably fixed to the bracket. This fixing method enhances the connection stability between the electroscope and the bracket, and prevents the testing end of the electroscope from shaking during the testing process.
[0010] Furthermore, both side walls of the bracket body are respectively provided with limiting holes, and fasteners are passed through the limiting holes to fix the fixing block to the bracket body.
[0011] With the above technical solution, the limiting hole provides a mounting position for the fastener, thereby ensuring that the fixing block can be firmly positioned on the bracket body. This helps prevent the fixing block from shifting during the test, ensuring the accuracy and stability of the electroscope's working state.
[0012] Furthermore, the limiting hole includes an upper limiting hole and a lower limiting hole, and the fixing block can be fixed at either the upper limiting hole or the lower limiting hole.
[0013] Using the above-mentioned technical solution, the two side walls of the bracket body are respectively provided with upper limit holes and lower limit holes to provide different fixing positions for the fixing block. The fixing block is fixed to the upper limit hole or the lower limit hole according to the length of the electroscope. This design greatly improves the flexibility and practicality of installation.
[0014] Furthermore, the bottom opening is in a trumpet shape that shrinks from the bottom to the top.
[0015] Using the aforementioned technical solution, the bottom opening of the bracket body is designed into a trumpet shape. This design increases the drone's field of view through the opening during flight, making it easier for the drone to locate the conductor under test. This allows the tester to quickly contact the conductor under test, reducing testing time and improving testing efficiency.
[0016] Furthermore, it also includes a drone and a connecting bracket, the top of the bracket body is provided with a connecting hole, one end of the connecting bracket is connected to the drone, and the other end is connected to the connecting hole.
[0017] The aforementioned technical solution allows the connecting bracket to stably connect the drone to the electrical test bracket. The connection holes and the connecting portion of the connecting bracket ensure a secure and reliable connection between the drone and the electrical test bracket during flight, preventing it from falling off or shaking, thereby improving the stability and reliability of the connection.
[0018] Furthermore, the connection hole is arranged at the center position of the top end of the bracket body, and the bracket body is arranged axially symmetrically.
[0019] The aforementioned technical solution, with the connection hole positioned at the center of the top of the bracket body, helps maintain a balanced connection between the drone and the electrical test bracket. This ensures that the drone does not generate unnecessary torque due to offset connection points during flight, thereby maintaining flight stability. The axisymmetry of the bracket body further enhances overall stability. This axisymmetric layout allows the bracket to evenly distribute stress when subjected to force, reducing stress concentration caused by irregular shapes and thus improving the bearing stability of the bracket body.
[0020] Furthermore, the distance from the limiting hole to the top of the bracket body is smaller than the distance from the midpoint of the bracket body to the top of the bracket body.
[0021] With the aforementioned technical solution, the stopper hole is located closer to the top of the bracket body, with the distance from the bracket body's midpoint to the top being less than the distance from the bracket body's midpoint to the top. This shifts the bracket body's center of gravity downward, reducing the potential for sway or tilt caused by excessively high connecting components. This downward center of gravity prevents the bracket body from becoming unstable when subjected to external forces. Furthermore, this downward center of gravity makes it easier to find the balance point during electrical testing, thereby improving testing efficiency.
[0022] Furthermore, the bracket body and the fixing block are both made of insulating materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0029] like Figure 1As shown, the present invention provides a UAV electrical testing device, including an electrical testing bracket and an electrical tester 2. The electrical testing bracket includes a bracket body 1 and an installation space 11 surrounded by the bracket body 1. The bottom end of the installation space 11 is provided with an opening for the entry and exit of wires (the direction described in the embodiment is consistent with the direction indicated in the accompanying drawings). The electrical tester 2 is placed in the installation space 11. The electrical tester 2 includes a connecting end 21 and an electrical testing end 22. The connecting end 21 is fixedly mounted on the bracket body 1, and the electrical testing end 22 is open toward the bottom end.
[0030] As can be understood, the bracket body 1 defines an installation space 11 with an open bottom end. The electroscope 2 is placed within the installation space 11, and the connection end 21 of the electroscope 2 is fixedly connected to the bracket body 1. The electroscope 2's test end 22 is positioned toward the bottom opening of the bracket body 1, and is used to contact the wire to verify its charge status. When a drone carrying the test device flies over the wire to be tested, the test end 22 contacts the wire to perform the test. This design significantly shortens the time required for testing and improves testing efficiency. Furthermore, the electroscope 2 is fixedly mounted to the bracket body 1, maintaining a stable test state. This avoids inaccurate test results caused by improper operation. Furthermore, the direct contact between the test end 22 and the wire ensures the accuracy of the test results. Using a drone for testing also avoids the high-risk operation of workers directly contacting the wire. Remotely controlling a drone for testing can significantly reduce safety risks during operation.
[0031] The electroscope 2 is a non-contact electroscope 2 , and the connection end 21 of the electroscope 2 is fixed to the inner top wall of the bracket body 1 by fasteners, generally detachable bolts, which makes it easy to disassemble the electroscope 2 and the bracket body 1 .
[0032] In addition, the electrical tester 2 is also provided with an audible and visual alarm LED light and a sound collection device is installed nearby and is wirelessly connected to a mobile terminal, such as a mobile phone. The staff at the bottom can transmit the electrical test information in real time through the mobile terminal, and provide the ground staff with information on whether the tested line is energized or out of power. If the tested line is energized, the alarm sound emitted by the audible and visual alarm LED light of the non-contact electrical tester 2 is transmitted to the staff's mobile terminal in real time; if the tested line is out of power, the staff's mobile terminal will not emit an alarm sound.
[0033] It should be noted that in this embodiment, the mass of the entire bracket body 1 is 1.8 kg. If the mass of the bracket body 1 is too heavy, the drone will be unstable during flight; if the mass of the bracket body 1 is too light, it will be disturbed by external conditions such as wind during flight and lose balance. However, in specific usage, the mass data obtained in this embodiment is only for reference, and the specific weight depends on the specific usage conditions and the maximum weight that the aircraft can bear.
[0034] The bracket body 1 is made of insulating bakelite. Its bottom opening is shaped like a trumpet. This larger opening increases the drone's field of view during flight, making it easier for the drone to locate the conductor under test. This allows the electroscope 2 to quickly contact the conductor under test, reducing testing time and improving efficiency.
[0035] like Figure 2 As shown, the length L1 of the bracket body 1 measured in the longitudinal direction is 460 mm, the width L2 at the top is 120 mm, and the width L3 at the bottom is 315 mm.
[0036] The width L4 of the top of the installation space 11 is 60 mm, and the width L5 of the middle end is 40 mm. It can match a wire with a maximum cross-sectional area of 1200 m2. In fact, the installation space 11 is a hollow part directly in the middle of the main body, which not only facilitates the installation of the electroscope 2, but also reduces the overall weight of the bracket body 1.
[0037] The data mentioned above are all specific values in this embodiment, but during specific use, the size of the bracket body 1 can be adjusted according to the specific environment.
[0038] The test circuit bracket also includes a fixing block 12, which is installed on the test circuit end 22 of the test circuit 2. A through hole is provided on the fixing block 12 for the test circuit end 22 to pass through. The height of the fixing block 12 is less than the height of the test circuit end 22. The test circuit end 22 passes through the through hole so that the test circuit end 22 passes through. The fixing block 12 is fixed to the bracket body 1, ensuring that the test circuit end 22 of the test circuit 2 can be stably fixed to the bracket. This fixing method enhances the connection stability between the test circuit 2 and the bracket, and prevents the test circuit end 22 of the test circuit 2 from shaking during the test process.
[0039] To better secure the fixing block 12 to the body, limiting holes 13 are provided on both side walls of the bracket body 1. Fasteners are passed through the limiting holes 13 to secure the fixing block 12 to the bracket body 1. The limiting holes 13 provide a mounting position for the fasteners, thereby ensuring that the fixing block 12 can be firmly positioned on the bracket body 1. This helps prevent the fixing block 12 from shifting during the electroscope test, ensuring the accuracy and stability of the electroscope 2's working state.
[0040] Specifically, the limit hole 13 includes an upper limit hole and a lower limit hole 132. The fixing block 12 is fixed to either the upper limit hole 131 or the lower limit hole 132. The upper limit hole 131 and the lower limit hole 132 provide different fixing positions for the fixing block 12. The fixing block 12 is fixed to the upper limit hole 131 or the lower limit hole 132 according to the length of the electroscope 2. This design greatly improves the flexibility and practicality of installation.
[0041] In fact, the upper limit hole 131 and the lower limit hole 132 are distributed above and below the side wall of the direct body, and the two side walls are symmetrically arranged. The mentioned bracket body 1 can match two types of electroscopes 2. One type of electroscope 2 matches 35kV and 110kV and is fixedly installed in the upper limit hole 131; the other type of electroscope 2 matches 220kV and 500kV and is fixedly installed in the lower limit hole 132.
[0042] The material of the fixing block 12 is also selected to be an insulating bakelite material, and the fixing block 12 and the limiting hole 13 can be fastened together by bolts.
[0043] The electrical test device also includes an insulated connecting bracket 14. A connecting hole 15 is provided at the top of the bracket body 1. One end of the connecting bracket is connected to the drone, and the other end is connected to the connecting hole 15. This connecting bracket allows the drone to be stably connected to the electrical test bracket. The connection between the connecting hole 15 and the connecting bracket ensures a secure and reliable connection between the drone and the electrical test bracket during flight, preventing it from falling off or shaking, thereby improving the stability and reliability of the connection.
[0044] In addition, the length of the insulating connection bracket 14 should be reasonably selected according to the specific level of the measured voltage to ensure a safe distance between the drone and the wire.
[0045] The insulating connecting bracket 14 can be made of hard plastic with a certain hardness, such as PC.
[0046] To better ensure the stability of the drone during flight, the connection hole 15 is located at the center of the top of the bracket body 1, and the bracket body 1 is arranged axially symmetrically. This helps maintain a balanced connection between the drone and the electrical test bracket. This ensures that the drone does not generate unnecessary torque due to offset connection points during flight, thereby maintaining flight stability. The axial symmetry of the bracket body 1 further enhances the overall stability. The axially symmetrical layout allows the bracket to evenly distribute stress when subjected to force, reducing stress concentration caused by irregular shapes, thereby improving the bearing stability of the bracket body 1.
[0047] Furthermore, the distance between the retaining hole 13 and the top of the bracket body 1 is shorter than the distance between the midpoint of the bracket body 1 and the top of the bracket body 1, shifting the center of gravity downward. This reduces the risk of sway or tilt caused by excessively high connecting components. This downward center of gravity prevents the bracket body 1 from becoming unstable when subjected to external forces. Furthermore, this downward center of gravity makes it easier to find a balance point during electrical testing, thereby improving testing efficiency.
[0048] In summary, when the test device is in operation, a worker controls the drone to take off from the ground. Once it reaches a certain altitude, the drone's attached bracket is positioned vertically. The worker then flies the drone directly above the conductor to be tested. Because the test device's bottom opening is shaped like a trumpet, narrowing from bottom to top and with a larger opening, the drone can accurately locate the conductor. Once located, the drone slowly descends toward the conductor until the test terminal 22 of the tester 2 makes contact. Because the test terminal 22 is secured with a fixing block 12, which is fixedly connected to the bracket body 1, the fixed block 12 maintains stability, ensuring good contact between the tester and the tester 2, revealing the conductor's true condition. If the test line is live, an alarm signal from the tester 2's audible and visual alarm LED is transmitted in real time to the operator's mobile device. If the test line is de-energized, the operator's mobile device does not emit an alarm. After the test is complete, the worker controls the drone to ascend, and after the test device is completely free of the conductor, it flies horizontally away, allowing the operator to proceed to the next test location. When testing the power of multi-layer transmission lines installed on the same tower, the power should be tested phase by phase in the order of testing the lower layers first and then the higher layers.
[0049] This power testing device has been proven to be suitable for testing 35kV-500kV transmission lines. Multiple field trials have shown that testing a three-phase power outage takes approximately two minutes, significantly improving operational efficiency and reducing safety risks. The test process eliminates the need for personnel to climb a tower and hold a joystick, enabling the use of a machine instead of a human. Furthermore, the drone's operation is stable and reliable.
[0050] In addition to the above-mentioned preferred embodiments, the present invention has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
