Description
Technical Field
[0001] This utility model relates to the field of high-voltage line voltage testing technology, and in particular to a drone voltage testing device for high-voltage lines in wind farms. Background Technology
[0002] With the continuous expansion of the power grid, the requirements for the surveying, acceptance, and operation and maintenance of transmission lines and equipment are becoming increasingly stringent. The integration of conventional methods and intelligent technologies is a growing trend in technological development. Pilot projects in multiple locations have implemented collaborative operation modes involving helicopters, drones, and manual labor on transmission lines. In the future, drone systems will serve as tools for transmission line operation and maintenance teams, overcoming various difficulties associated with manual methods, improving operational efficiency and quality, and enhancing the safety management of transmission lines. This will become a future trend in power line acceptance and operation and maintenance.
[0003] Chinese utility model patent CN217836046U discloses a grounding device for drone-based acoustic and optical voltage detectors. While this prior art replaces manual grasping of acoustic and optical voltage detectors for voltage testing and eliminates the risk of electric shock for workers, the voltage detector fixed to the bottom of the drone has a significant impact on drone recovery. Because the voltage detector is large, the drone's support frame cannot make priority contact with the ground, requiring the recovery position to be arranged in advance and manual recovery. This not only wastes a lot of time but also requires operators to have a high level of skill. Therefore, it is necessary to design a drone voltage detector that can automatically separate the drone from the voltage detector. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a drone-based voltage testing device for high-voltage lines in wind farms.
[0005] This utility model is achieved using the following technical solution: a wind farm high-voltage line unmanned aerial vehicle (UAV) voltage testing device, including a UAV, with support frames symmetrically installed on both sides of the bottom of the UAV, and a voltage testing component for testing the high-voltage line between the two support frames, and a separation component on the top of the voltage testing component for automatically separating the voltage testing component from the UAV when the UAV is recovered, and fixing components for fixing the voltage testing component to the support frame on both sides of the voltage testing component.
[0006] Using the above technical solution, the staff installs the voltage detection component onto the drone. After the voltage detection is completed, the drone descends, causing the voltage detection component to come into contact with the ground, thus giving the voltage detection component an upward force. This causes the voltage detection component to move upward, and with the help of the separation component, the part of the voltage detection component that exceeds the drone's support frame can be separated. The voltage detection component automatically falls to the ground, and the drone can also fall to the ground and be recovered.
[0007] As a further improvement to the above solution, the voltage detection assembly includes a support plate disposed between two support frames. A voltage detector is provided at the bottom of the support plate, a first connecting block is fixedly installed at the top of the voltage detector, a second connecting block is fixedly installed at the top of the first connecting block, the top of the second connecting block extends upward through the support plate, and a limit plate is fixedly installed at one end of the second connecting block located at the top of the support plate.
[0008] With the above technical solution, the electroscope is mounted on the carrier plate through the first connecting block, the second connecting block, and the limiting plate. The electroscope can be completely removed from the drone by removing the carrier plate.
[0009] As a further improvement to the above solution, the bearing plate is provided with a convex limiting groove, which is open, and the second connecting block is located inside the limiting groove.
[0010] With the above technical solution, the upward movement of the electroscope will cause the second connecting block to move upward, and the first connecting block will move to the opening of the limiting groove. In this way, the first connecting block can be removed from the limiting groove, making it convenient to remove the connected electroscope from the carrier plate.
[0011] As a further improvement to the above solution, the separation component includes a fixed plate fixedly installed on the top of the support plate. The fixed plate has a sliding groove on the side near the limiting plate. A sliding block is slidably installed inside the sliding groove. The side of the sliding block protruding from the sliding groove is fixedly installed with the limiting plate.
[0012] With the above technical solution, when the electroscope moves upward, the limiting plate will also move upward. The sliding block and the sliding groove can prevent the limiting plate from shifting upward.
[0013] As a further improvement to the above solution, a spring-loaded outlet is provided on one side of the top of the fixed plate, and the spring-loaded outlet is connected to the sliding groove.
[0014] With the above technical solution, once the sliding block rises to the top of the sliding groove, it can be removed from the ejector port.
[0015] As a further improvement to the above solution, a limiting opening is provided on the side of the fixed plate away from the limiting plate. The limiting opening is connected to the sliding groove. A push rod is provided inside the limiting opening. Limiting discs are fixedly sleeved on both ends of the push rod. A limiting block is slidably sleeved on the push rod. The limiting block is slidably engaged with the limiting opening. A push spring is sleeved on the push rod. The two ends of the push spring abut against the adjacent limiting disc and the limiting block, respectively. A protrusion is fixedly installed on one side of one of the limiting discs. A push groove is provided on one side of the sliding block. The protrusion is located inside the push groove.
[0016] With the above technical solution, when the sliding block is inside the sliding groove, the push spring is compressed. The upward movement of the sliding block will cause the protrusion to move upward, so the limiting plate will move upward with the push rod. When the sliding block moves to the ejector outlet, the push spring will lose its compressive force and unfold. The unfolded push spring will push the adjacent limiting plate, so that the limiting plate will push the sliding block and push the sliding block out of the ejector outlet. In this way, the first connecting block can pass through the opening of the limiting groove and separate from the carrier plate, thus completing the separation of the voltage detector from the drone.
[0017] As a further improvement to the above solution, the fixing component includes a first half-ring fixedly installed on one side of the bearing plate, and a second half-ring rotatably installed on one side of the first half-ring.
[0018] With the above technical solution, the first half-ring and the second half-ring can be fixed on the support frame of the drone, thereby preventing the load-bearing plate from separating from the support frame.
[0019] As a further improvement to the above solution, a fixing block is fixedly installed on one side of each first half-ring, and a slot is formed on the bottom side of each fixing block. A fixing strip is fixedly installed on one side of each second half-ring, and an insert plate is fixedly installed on one side of each fixing strip. One side of each insert plate extends into the interior of the adjacent slot. A limiting plate is fixedly installed on the side of each insert plate located inside the slot. A fixing groove communicating with the slot is formed on one side of each fixing block, and each limiting plate is located inside the adjacent fixing groove.
[0020] By using the above technical solution, the insert plate is inserted into the slot, and the limiting plate is locked inside the fixing slot, thus forming a fixing effect, making it impossible for the first half ring and the second half ring to separate.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] This invention, by setting up a voltage detection component, a separation component, and a fixing component, allows workers to install the voltage detection component onto the drone. After the voltage detection is completed, the drone descends, causing the voltage detection component to come into contact with the ground, thus giving the voltage detection component an upward force. This causes the voltage detection component to move upward, and with the help of the separation component, the part of the voltage detection component that exceeds the drone's support frame can be separated. The voltage detection component automatically falls to the ground, and the drone can also land on the ground and be recovered. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0031] Please combine Figures 1-5 This embodiment of a wind farm high-voltage line unmanned aerial vehicle (UAV) voltage testing device includes a UAV 1. Support frames 2 are symmetrically installed on both sides of the bottom of the UAV 1. A voltage testing component for testing the high-voltage line is provided between the two support frames 2. A separation component is provided on the top of the voltage testing component to automatically separate the voltage testing component from the UAV 1 when the UAV 1 is recovered. Fixing components are provided on both sides of the voltage testing component to fix the voltage testing component to the support frame 2.
[0032] The staff installs the voltage testing component onto the drone 1. After the voltage testing is completed, the drone 1 descends, causing the voltage testing component to come into contact with the ground. This gives the voltage testing component an upward force, causing it to move upward. With the help of the separation component, the part of the voltage testing component that exceeds the support frame 2 of the drone 1 can be separated. The voltage testing component automatically falls to the ground, and the drone 1 can also fall to the ground and be recovered.
[0033] The voltage testing assembly includes a support plate 301 disposed between two support frames 2. A voltage detector 302 is disposed at the bottom of the support plate 301. A first connecting block 303 is fixedly installed on the top of the voltage detector 302. A second connecting block 304 is fixedly installed on the top of the first connecting block 303. The top of the second connecting block 304 extends upward through the support plate 301. A limiting plate 305 is fixedly installed at one end of the second connecting block 304 located at the top of the support plate 301. A convex limiting groove 6 is provided on the support plate 301. The limiting groove 6 is open. The second connecting block 304 is located inside the limiting groove 6.
[0034] The voltage detector 302 is mounted on the support plate 301 via the first connecting block 303, the second connecting block 304, and the limiting plate 305. The voltage detector 302 can be completely removed from the drone 1 by removing the support plate 301.
[0035] When the electroscope 302 moves upward, the second connecting block 304 will move upward, and the first connecting block 303 will move to the opening of the limiting groove 6. In this way, the first connecting block 303 can be removed from the limiting groove 6, making it convenient to remove the connected electroscope 302 from the carrier plate 301.
[0036] The separation assembly includes a fixing plate 401 fixedly installed on the top of the support plate 301. A sliding groove 7 is provided on the side of the fixing plate 401 near the limiting plate 305. A sliding block 402 is slidably installed inside the sliding groove 7. The side of the sliding block 402 protruding from the sliding groove 7 is fixedly installed with the limiting plate 305.
[0037] When the voltage detector 302 moves upward, the limiting plate 305 also moves upward. The sliding block 402, in conjunction with the sliding groove 7, ensures that the upward movement of the limiting plate 305 will not result in any deviation.
[0038] A spring outlet 8 is provided on one side of the top of the fixed plate 401, and the spring outlet 8 is connected to the sliding groove 7.
[0039] Once the sliding block 402 rises to the top of the sliding groove 7, it can be removed from the ejector outlet 8.
[0040] A limiting opening 9 is provided on the side of the fixed plate 401 away from the limiting plate 305. The limiting opening 9 is connected to the sliding groove 7. A push rod 10 is provided inside the limiting opening 9. Limiting discs 11 are fixedly sleeved on both ends of the push rod 10. A limiting block 12 is slidably sleeved on the push rod 10. The limiting block 12 is slidably engaged with the limiting opening 9. A push spring 13 is sleeved on the push rod 10. The two ends of the push spring 13 abut against the adjacent limiting discs 11 and limiting blocks 12 respectively. A protrusion 14 is fixedly installed on one side of one of the limiting discs 11. A push groove is provided on one side of the sliding block 402. The protrusion 14 is located inside the push groove.
[0041] When the sliding block 402 is inside the sliding groove 7, the push spring 13 is compressed. The upward movement of the sliding block 402 will cause the protrusion 14 to move upward, so the limiting plate 11 will move upward along with the push rod 10. When the sliding block 402 moves to the ejection outlet 8, the push spring 13 will lose its compressive force and unfold. The unfolded push spring 13 will push the adjacent limiting plate 11, so that the limiting plate 11 will push the sliding block 402 and push the sliding block 402 out of the ejection outlet 8. In this way, the first connecting block 303 can pass through the opening of the limiting groove 6 and separate from the bearing plate 301, thus completing the separation of the electroscope 302 from the drone 1.
[0042] The fixing assembly includes a first half-ring 501 fixedly installed on one side of the bearing plate 301, a second half-ring 502 rotatably installed on one side of the first half-ring 501, a fixing block 503 fixedly installed on one side of each first half-ring 501, a slotting groove opened on the bottom side of each fixing block 503, a fixing strip 504 fixedly installed on one side of each second half-ring 502, an insert plate 505 fixedly installed on one side of each fixing strip 504, one side of each insert plate 505 extending into the interior of the adjacent slotting groove, a limiting plate 506 fixedly installed on the side of each insert plate 505 located inside the slotting groove, a fixing groove communicating with the slotting groove opened on one side of each fixing block 503, and each limiting plate 506 located inside the adjacent fixing groove.
[0043] The first half-ring 501, together with the second half-ring 502, can be fixed on the support frame 2 of the drone 1, thereby preventing the bearing plate 301 from separating from the support frame 2. The insert plate 505 is inserted into the slot, so that the limiting plate 506 is stuck inside the fixing slot, thus forming a fixing effect, so that the first half-ring 501 and the second half-ring 502 cannot be separated.
[0044] The implementation principle of the unmanned aerial vehicle (UAV) voltage testing device for high-voltage lines in a wind farm in this embodiment is as follows: The operator first places the bearing plate 301 on two support frames 2, rotates the second half ring 502, and inserts the insert plate 505 on the second half ring 502 into the slot of the fixing block 503 on the first half ring 501. In this way, the limiting plate 506 will be locked with the fixing slot of the fixing block 503, and the bearing plate 301 will be fixed on the support frame 2.
[0045] Insert the sliding block 402 onto the limiting plate 305 and raise it to one side of the ejector outlet 8. Then slide the push rod 10 upward so that the push rod 10 and the sliding block 402 are at the same level. Next, insert the first connecting block 303 into the limiting groove 6 of the bearing plate 301. In this way, the sliding block 402 will be inserted into the interior of the ejector outlet 8, and the protrusion 14 will be inserted into the push groove. Due to the push of the sliding block 402, the limiting plate 11 that fixes the protrusion 14 will be pushed by the sliding block 402 to compress the push spring 13. At this time, the push spring 13 will be in a compressed state due to the position restriction of the limiting plate 11 and the limiting block 12.
[0046] Next, pull down the first connecting block 303 so that the second connecting block 304 is inside the limiting groove 6, and the limiting plate 305 is attached to the top of the bearing plate 301. In this way, the position of the electroscope 302 located at the bottom of the first connecting block 303 will be fixed, because the second connecting block 304 is larger than the opening of the limiting groove 6 and cannot slide out from the opening.
[0047] The sliding block 402 will also move down into the sliding groove 7 along with the limiting plate 305. The protrusion 14 will carry the limiting plate 11 down, and finally the limiting plate 11, the push rod 10, the limiting block 12, and the push spring 13 will all move to the bottom of the limiting port 9, thus completing the installation of the voltage detector 302.
[0048] After the voltage detector 302 completes its voltage testing, the drone 1 simply descends normally, allowing the voltage detector 302 to first contact the ground. As the drone 1 continues to descend, the voltage detector 302 will push the first connecting block 303 in the reverse direction. The first connecting block 303 pushes the second connecting block 304 upward, and the second connecting block 304 pushes the limiting plate 305 upward. Finally, the sliding block 402 moves upward. Thus, when the first connecting block 303 moves to the opening of the limiting groove 6, the sliding block 402 will also move into the interior of the ejector outlet 8. At this point, the voltage detector 302 will be pushed upward. Spring 13 will unfold and push sliding block 402 out of outlet 8. Because sliding block 402 loses the manual pushing force of the operator during installation and the restriction of sliding groove 7, it can no longer stop the unfolding of spring 13. When sliding block 402 is pushed out of outlet 8, it will rotate around the point where the electroscope 302 contacts the ground. Because the electroscope 302 is still in contact with the ground at this time, the first connecting block 303 will also slide out from the opening of the limiting groove 6. This completes the separation of electroscope 302 from carrier plate 301.
[0049] Then, the drone 1 only needs to fly upwards to completely separate from the voltage detector 302, and it can land on the ground to wait for recovery.
[0050] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
