Description
Technical Field
[0001] This application relates to the field of zero-value detection equipment for unmanned aerial vehicles (UAVs), and more particularly to a zero-value detection device for UAVs. Background Technology
[0002] The UAV zero-value detection device is mainly used for the maintenance and inspection of power transmission lines in the power system, especially for the zero-value detection of insulator strings on high-voltage lines. Insulators are one of the important electrical devices in power transmission lines, and their performance directly affects the safe and stable operation of the power transmission system. With the continuous development of the power system, higher requirements are placed on the detection accuracy and efficiency of insulators.
[0003] Currently, the most common method for zero-value detection of insulator strings is manual inspection. Manual inspection usually requires workers to climb to high places and use handheld testing instruments to check the condition of each insulator. Although this method is intuitive and reliable, it is labor-intensive, inefficient, and carries a high safety risk.
[0004] Therefore, providing a detection device to reduce high-altitude operations and improve operational safety is an urgent problem to be solved. Utility Model Content
[0005] To reduce high-altitude operations and improve operational safety, this application provides a zero-value detection device for unmanned aerial vehicles (UAVs).
[0006] The UAV zero-value detection device provided in this application adopts the following technical solution:
[0007] A zero-value detection device for unmanned aerial vehicles (UAVs) includes:
[0008] The drone body with a shell;
[0009] Mounting frame, which is connected to the shell of the UAV body;
[0010] Zero-value detection component, the zero-value detection component being mounted on the mounting frame; and,
[0011] In a first direction, the clamping assembly is provided at each of the two ends of the zero-value detection assembly, and the clamping assembly includes:
[0012] An insulating crossbar, said insulating crossbar being connected to the mounting frame; and,
[0013] Side rods are fixedly connected to the insulating crossbar. The insulating crossbar has side rods on both sides in the first direction. A clamping area with a feed inlet on one side is formed between the insulating crossbar and the two side rods. The feed inlet of the clamping area is set towards the side away from the insulating crossbar. The direction of entering the clamping area from the feed inlet is the depth direction of the clamping area. The depth direction of the clamping area is parallel to the second direction.
[0014] By adopting the above technical solution, efficient and accurate zero-value detection of insulator strings on transmission lines can be achieved, effectively reducing the high-altitude work of traditional manual inspections, lowering labor intensity and safety risks, and improving detection efficiency. Specifically, the device uses a drone to carry clamping components and zero-value detection components, realizing automatic detection under remote control and avoiding the dangers of personnel working at heights. At the same time, the design of the clamping components ensures that the insulator strings can be firmly clamped, ensuring the stability of the detection process. In use, the drone only needs to drive the clamping components to move so that the insulator strings enter the clamping area.
[0015] The width of the clamping area is formed in the third direction between the optional side bars on both sides, and the width of the clamping area gradually increases from the insulating crossbar to the feed inlet side.
[0016] By adopting the above technical solution, the width design of the clamping area makes it easier for the insulator string to enter the clamping area, improving the convenience and efficiency of the testing process.
[0017] Optionally, the side rod is an insulating rod.
[0018] By adopting the above technical solution, the insulating rod as a side rod can effectively prevent current from being transmitted to the UAV body or other parts through the clamping assembly, thus improving the safety of the testing process. At the same time, the use of the insulating rod can also prevent short circuits or interference caused by conductivity, ensuring the accuracy and reliability of the test results.
[0019] Optionally, a locking assembly is also included, with each of the side rods having a corresponding locking assembly, the locking assembly comprising:
[0020] An insulating rotating rod, the insulating rotating rod being rotatably connected to the side rod via a first rotating shaft, the first rotating shaft being parallel to a first direction; and...
[0021] A drive motor is connected between the insulating rotating rod and the side rod, and is used to drive the insulating rotating rod to rotate along the side rod via the first rotating shaft, so that the insulating rotating rod can be adjusted between a locked posture and an unlocked posture;
[0022] When the insulating rotating rod is in the unlocked position, the insulating rotating rod rotates to the side where the two side rods are far apart from each other;
[0023] When the insulating rotating rod is in the locked position, the insulating rotating rod rotates to the side of the insulating crossbar that is close to the feed inlet.
[0024] By adopting the above technical solutions, the clamping stability of the insulator string can be effectively improved, preventing the insulator string from falling off due to vibration or airflow during the drone's flight, thus ensuring the safety and reliability of the testing process. At the same time, by controlling the rotation of the insulator rotating rod with a drive motor, the clamping and releasing operations are automated, improving testing efficiency.
[0025] Optionally, the mounting frame includes:
[0026] A lateral support rod, which connects the shell of the UAV body and the zero-value detection component; and,
[0027] Two second linear drive members are provided at each end of the transverse support rod in the first direction. The driving direction of the second linear drive members is parallel to the second direction, and one end of the second linear drive member is connected to the transverse support rod, and the other end is connected to the insulating crossbar.
[0028] By adopting the above technical solution, this UAV zero-value detection device can achieve precise positioning and stable clamping of insulator strings, ensuring stability during the detection process and effectively avoiding measurement errors caused by insecure clamping. Simultaneously, the second linear drive component moves the clamping assembly in the second direction, allowing the position of the clamping assembly in the second direction to flexibly adapt to insulator strings of different sizes, thus improving the device's applicability.
[0029] Optionally, the lateral support rod includes:
[0030] A fixing rod is connected between the shell of the UAV body and the zero-value detection component;
[0031] A movable rod is provided at each end of the fixed rod in a first direction; the movable rod is connected to the second linear drive member, and the movable rod is slidably connected to the fixed rod along the first direction; and...
[0032] An elastic element is provided, wherein the extension and retraction direction of the elastic element is parallel to the first direction, and the elastic element is connected between each of the movable rods and the fixed rods.
[0033] By adopting the above technical solution, the sliding connection design between the fixed rod and the movable rod allows the total length of the transverse support rod to be flexibly adjusted according to actual testing needs, thereby adapting to insulator strings of different lengths. At the same time, the design of the elastic element not only provides the necessary elastic support to ensure that the movable rod quickly resets when subjected to external disturbances, but also effectively absorbs vibration during the testing process, ensuring the accuracy of the test results.
[0034] Optionally, it also includes a length-fixing component, the length-fixing component comprising:
[0035] An iron metal rod, one end of which is fixedly connected to the fixed rod, and the other end extends to the side of the movable rod, and each side of the movable rod is provided with the iron metal rod.
[0036] An electromagnet is fixedly connected to the fixed rod, and the electromagnet is in contact with the ferrous metal rod.
[0037] By adopting the above technical solution, when the electromagnet is energized, the electromagnet and the ferrous metal rod generate a magnetic attraction, which fixes the position of the movable rod relative to the fixed rod, thereby ensuring that the total length of the transverse support rod remains unchanged, avoiding changes in the length of the support rod caused by external factors, and improving the safety and accuracy of the detection process.
[0038] Optionally, the zero-value detection component includes:
[0039] A first linear drive member, wherein the driving direction of the first linear drive member is parallel to a first direction; and,
[0040] A resistance detection probe is provided, with one end of the first linear drive component fixedly connected to the resistance detection probe and the other end connected to the mounting frame.
[0041] By adopting the above technical solution, the driving direction of the first linear drive component is parallel to the first direction, which enables the resistance detection probe to move precisely along the arrangement direction of the insulator string, thereby realizing the detection of each insulator one by one; in addition, the resistance detection probe is connected to the detection controller, which can transmit data in real time during the detection process, further improving the detection efficiency and accuracy.
[0042] In summary, this application includes at least one of the following beneficial technical effects:
[0043] 1. This application enables efficient and accurate zero-value detection of insulator strings on transmission lines, effectively reducing the high-altitude work required for traditional manual inspections, lowering labor intensity and safety risks, and improving detection efficiency;
[0044] 2. The width design of the clamping area makes it easier for the insulator string to enter the clamping area, improving the convenience and efficiency of the inspection process;
[0045] 3. The sliding connection design between the fixed rod and the movable rod allows the total length of the transverse support rod to be flexibly adjusted according to actual testing needs, thus adapting to insulator strings of different lengths. Attached Figure Description

[0050] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction", can be specifically referred to in the figure, where X represents the first direction X, Y represents the second direction Y, Z represents the third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.
[0051] This application discloses a zero-value detection device for unmanned aerial vehicles (UAVs). (Refer to...) Figure 1 and Figure 2 The drone zero-value detection device includes a drone body 1 with a shell 11, a mounting frame 2, a zero-value detection component 3, and a clamping component 4;
[0052] The zero-value detection component 3 is connected to the UAV body 1 via the mounting frame 2. The zero-value detection component 3 includes a mounting base 31, a first linear drive 34, a resistance detection probe 32, and a detection controller 33. The first linear drive 34 is driven parallel to a first direction. One end of the first linear drive 34 is fixedly connected to the mounting frame 2, and the other end is fixedly connected to the resistance detection probe 32. The resistance detection probe 32 is located at the end of the mounting base 31 away from the UAV. The detection controller 33 is fixedly connected to the mounting base 31. The resistance detection probe 32 is communicatively connected to the detection controller 33 and is used to detect the insulator string 01.
[0053] The mounting frame 2 includes a transverse support rod 21 and two second linear drive components 22;
[0054] The transverse support rod 21 is arranged parallel to the first direction. The transverse support rod 21 includes a fixed rod 211, a movable rod 212, and an elastic element 213. The fixed rod 211 is fixedly connected to the shell 11 of the UAV body 1. Specifically, a connecting rod 23 is fixedly connected to the end of the fixed rod 211 near the UAV body 1. The connecting rod 23 is fixedly connected to the shell 11 of the UAV body 1 through a flange. The mounting base 31 in the zero-value detection assembly 3 is fixedly connected to the fixed rod 211.
[0055] In this disclosure, both the fixed rod 211 and the movable rod 212 are insulating rods; both the fixed rod 211 and the movable rod 212 are parallel to the first direction. In the first direction, each end of the fixed rod 211 is provided with a movable rod 212, and the movable rod 212 is slidably connected to the fixed rod 211 along the first direction. Specifically, a sliding hole 2111 is formed through the fixed rod 211 along the first direction, and the movable rod 212 passes through the sliding hole 2111 and can slide within the sliding hole 2111 along the first direction. During the sliding process of the movable rod 212 along the fixed rod 211, it... The total length of the transverse support rod 21 can be changed; the extension and retraction direction of the elastic element 213 is parallel to the first direction, and each movable rod 212 and fixed rod 211 is connected with an elastic element 213. In this disclosure, the elastic element 213 is a compression spring. In order to install the elastic element 213, a mounting block 24 is protruded on the fixed rod 211 and the movable rod 212 respectively. One end of the elastic element 213 is fixedly connected to the mounting block 24 on the fixed rod 211, and the other end is fixedly connected to the mounting block 24 on the movable rod 212, so as to realize the elastic sliding of the movable rod 212 along the fixed rod 211.
[0056] Reference Figure 1 and Figure 2In order to lock the total length of the transverse support rod 21, in some embodiments of this application, a length fixing component 5 is also included. Each movable rod 212 and fixed rod 211 is provided with a corresponding length fixing component 5. The length fixing component 5 includes an iron metal rod 51 and an electromagnet 52. The iron metal rod 51 is fixedly connected to the fixed rod 211. The iron metal rod 51 is parallel to the first direction and extends to the side of the movable rod 212. The electromagnet 52 is fixedly connected to the movable rod 212 and contacts the iron metal rod 51. When the electromagnet 52 is energized, the electromagnet 52 can be fixed to the iron metal rod 51, thereby locking the total length of the transverse support rod 21.
[0057] Reference Figure 1 and Figure 2 Two second linear drive members 22 are spaced apart in the first direction. Each end of the transverse support rod 21 is provided with a second linear drive member 22. Specifically, each movable rod 212 is provided with a second linear drive member 22 at the end away from the fixed rod 211. Each second linear drive member 22 is provided with a clamping assembly 4 at the end away from the movable rod 212. The driving direction of the second linear drive member 22 is parallel to the second direction to drive the clamping assembly 4 to move along the second direction. In this disclosure, the second linear drive member 22 is an electric actuator. The outer shell of the second linear drive member 22 is fixedly connected to the movable rod 212, and the push rod of the second linear drive member 22 is fixedly connected to the clamping assembly 4.
[0058] Reference Figure 1 , Figure 2 and Figure 3 The clamping assembly 4 includes an insulating crossbar 41 and two side bars 42;
[0059] The insulating crossbar 41 is parallel to the third direction and is fixedly connected to the push rod of the second linear drive member 22;
[0060] Each end of the insulating crossbar 41 is fixedly connected to a side bar 42. A clamping area 43 with a feed inlet 44 on one side is formed between the insulating crossbar 41 and the two side bars 42. The feed inlet 44 of the clamping area 43 is set to face away from the crossbar. The direction of entering the clamping area 43 from the feed inlet 44 is the depth direction of the clamping area 43, and the depth direction of the clamping area 43 is parallel to the second direction. During construction, the clamping assembly 4 is moved by the UAV body 1 until the insulator string 01 passes through the feed inlet 44 and enters the clamping area 43. In order to facilitate the entry of the insulator string 01 into the clamping area 43, in some embodiments of this application, the width of the clamping area 43 gradually increases from the insulating crossbar 41 to the feed inlet 44. Specifically, the distance between the two side bars 42 in the third direction is the width of the clamping area 43. Preferably, the side bars 42 are insulating bars.
[0061] Reference Figure 3 To prevent the clamping assembly 4 from detaching from the insulator string 01, in some embodiments of this application, a locking assembly 6 is also included. Each side rod 42 is provided with a corresponding locking assembly 6. The locking assembly 6 includes an insulating rotating rod 61 and a drive motor 62. The insulating rotating rod 61 is rotatably connected to the side rod 42 through a first rotating shaft, which is parallel to a first direction. The drive motor 62 is connected between the side rod 42 and the insulating rotating rod 61 to provide power for the rotation of the insulating rotating rod 61 along the side rod 42. In this disclosure, the housing of the drive motor 62 is fixedly connected to the side rod 42, and the output shaft of the drive motor 62 is coaxially fixedly connected to the first rotating shaft so that the drive motor 62 drives the insulating rotating rod 61 to rotate along the side rod 42 through the first rotating shaft, thereby adjusting the insulating rotating rod 61 between a locked posture and an unlocked posture.
[0062] When the insulating rotating rod 61 is in the unlocked position, the insulating rotating rod 61 rotates to the side where the side rods 42 on both sides of the first direction are far apart;
[0063] When the insulating rotating rod 61 is in the locked position, the insulating rotating rod 61 rotates to the side of the insulating crossbar 41 that is close to the feed inlet 44, so that the insulator string 01 is clamped together by the insulating crossbar 41, the two side rods 42 and the insulating rotating rods 61 on both sides.
[0064] The implementation principle of the unmanned aerial vehicle (UAV) zero-value detection device in this application embodiment is as follows: the UAV body 1 drives the mounting frame 2 and clamping assembly 4 to move until the insulator string 01 enters the clamping area 43. Then, the drive motor 62 drives the insulating rotating rod 61 to rotate to lock the insulator string 01. Finally, the first linear drive member 34 drives the resistance detection probe 32 to the required position for detection.
[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
