Description

Technical Field

[0001] This invention relates to the field of power transmission line testing technology, and in particular to an insulator testing device and method based on unmanned aerial vehicles (UAVs). Background Technology

[0002] Currently, in order to test the safety of transmission lines, it is sometimes necessary to use insulator testing devices. These devices are used to test various performance indicators of insulators to ensure their safe and reliable operation.

[0003] The insulator testing device measures the potential difference of the insulator by means of voltage signal induction, and displays the test results digitally on an LCD screen. The device has a built-in high-voltage generator and a shielded circuit structure.

The motor is located inside the chassis, and its output end is fixedly connected to the end of the lifting threaded rod.

[0010] Preferably, the connecting rod assembly includes a push rod hinged to the side of the slider, a protrusion hinged to one end of the push rod, a rotating rod fixedly connected to one end of the protrusion, and a connecting block fixedly connected to one end of the rotating rod, wherein the free end of the rotating rod is hinged to the end of the fixed sleeve.

[0011] Preferably, the docking mechanism further includes an outer ring assembly, which includes an upper outer ring fixedly connected to the end of the chassis, a lower outer ring fixedly connected to the end of the docking plate, and an annular ramp formed on the outer surfaces of the upper and lower outer rings.

[0012] Preferably, the adsorption component includes: A docking block is fixedly connected to the end face of the chassis. An electromagnet is fixedly installed inside the docking block.

[0015] Secondly, the present invention provides a method for an insulator testing device based on a drone, which is implemented as described above. The specific steps of the method are as follows: Step 1: Take off with the drone carrying the docking mechanism and its detection device. Use a visual camera and ranging radar to identify the scene until the drone is at the docking position, and then perform the docking operation on the detection device. Step 2: The lifting assembly drives the connecting rod assembly to break open, so that the locking block is no longer locked onto the outer ring assembly, and the electromagnet no longer attracts the iron sleeve. Then the drone flies away and the detection device body is used for detection. Step 3: The drone flies to the main body of the detection device, and uses the docking block to align with the docking slot. At the same time, the electromagnet attracts the iron sleeve, and the change in magnetic force is transmitted through the Hall sensor. Then, the lifting component drives the connecting rod component to close, so that the clamping component clamps the outer ring component. The clamping information is transmitted through the visual camera. Then, the drone carries the main body of the detection device away.

[0016] Compared with the prior art, the technical effects of the present invention are as follows: 1. A drone carrying the docking mechanism and its detection device flies to the dropping position to perform dropping detection. Then, the lifting component drives the connecting rod component to rotate, which in turn moves the elastic component and the clamping component, causing the clamping component to loosen its grip on the docking plate and the adsorption component to stop adsorption. The drone then flies away, and the detection device is used for detection. When the detection device needs to be brought back later, the adsorption component is used to pre-dock and adsorb the drone to the docking plate. Then, the lifting component drives the connecting rod component to rotate, causing the clamping component and the elastic component to cooperate to perform a secondary docking and fixation of the docking plate. The drone then carries the docking mechanism and its detection device away. This design not only eliminates the need for manual climbing to drop the dropping plate, reducing the danger of detection, but also enables automatic docking and automatic separation. 2. By moving the rotating sleeve upward, the limiting block is inserted into the limiting groove, causing the rubber protrusion to engage with the inner groove. Then, the rotating sleeve is rotated, which drives the connecting sleeve to rotate, causing the connecting sleeve to separate from the connecting round block. Then, the detection device body is moved downward to complete the disassembly. During installation, the insert block is inserted into the slot, and then the rotating sleeve is rotated in the opposite direction to screw the connecting sleeve and the connecting round block together. This design makes it convenient for users to install or disassemble the detection device body. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides, for example Figures 1-7 The image shows an insulator testing device based on a drone.

[0027] Example 1: Includes a detection device body 11 located below the drone. A docking mechanism is provided between the detection device body 11 and the drone. The docking mechanism includes a fixed frustum 1 located at the bottom of the drone. A lifting assembly 4 is fixedly connected to the bottom of the fixed frustum 1. A connecting rod assembly 5 is hinged to the side of the lifting assembly 4, and the lifting assembly 4 is used to drive the connecting rod assembly 5 to rotate. An elastic assembly 6 is fixedly connected to the end of the connecting rod assembly 5, and a clamping assembly 7 is provided on the elastic assembly 6. A docking plate 13 is located below the lifting assembly 4. An adsorption assembly 9 is provided between the docking plate 13 and the lifting assembly 4, and the adsorption assembly 9 is used for pre-connection between the docking plate 13 and the lifting assembly 4. A connecting assembly 10 is provided between the detection device body 11 and the docking plate 13, and the connecting assembly 10 is used to connect the docking plate 13 and the detection device body 11. The drone carries the docking mechanism and its detection device body 11 to the landing position. The process involves a series of steps, including: a drop test, a lifting assembly 4 driving a connecting rod assembly 5 to rotate, which in turn causes the elastic assembly 6 and its clamping assembly 7 to move together. This causes the clamping assembly 7 to loosen its grip on the docking plate 13, and the adsorption assembly 9 to cease adsorption. The drone then flies away, and the detection device body 11 performs the final inspection. If the detection device body 11 needs to be brought back later, the adsorption assembly 9 is used to pre-dock and adsorb the drone onto the docking plate 13. Then, the lifting assembly 4 drives the connecting rod assembly 5 to rotate, causing the clamping assembly 7 and the elastic assembly 6 to engage and secure the docking plate 13 a second time. The drone then carries the docking mechanism and the detection device body 11 away. This design eliminates the need for manual climbing for drop testing, reducing the risk of accidents, and enables automatic docking and separation. The specific detection process of the detection device body 11 is existing technology and will not be elaborated here.

[0028] Furthermore, the elastic component 6 includes a fixed frame 601, which is connected to one end of the connecting rod assembly 5. The upright 602 is fixedly connected to the inside of the fixed frame 601. A through groove 603 is provided in the middle of the upright 602, and a pushing spring 604 is sleeved on the outer surface of the upright 602.

[0029] Furthermore, the clamping assembly 7 includes a U-shaped block 701, which is sleeved on the outside of the upright 602. The U-shaped block 701 has a connecting threaded groove 702 inside, and guide grooves 703 at both ends. A positioning block 704 is disposed on one side of the U-shaped block 701, and guide blocks 705 are fixedly connected to both ends of the positioning block 704. A through hole 706 is formed in the middle of the positioning block 704, and a connecting bolt 707 is inserted into the through hole 706. One end of the connecting bolt 707 passes through the through groove 603 and is threadedly connected to the inside of the connecting threaded groove 702. A rectangular block 709 is fixedly connected to the outer surface of the U-shaped block 701, and a locking block 708 is fixedly connected to one end of the rectangular block 709. The locking block 708 is inclined on the side near the lifting assembly 4; the inclined side facilitates locking. Block 708 can withstand pressure well, thus allowing the locking block 708 to move. By rotating the connecting bolt 707, the connecting bolt 707 is no longer connected to the connecting thread groove 702. Then, the positioning block 704 is moved outward, separating the positioning block 704 from the U-shaped block 701. At this point, the locking block 708 can be disassembled, making it easy to replace the locking block 708 with one of appropriate thickness. After the spring 604 pushes the locking block 708 to reset, the space between the inclined sides of the two locking blocks 708 can smoothly compress the outer ring assembly 8, avoiding motion interference. During installation, the triangular guide block 705 is quickly connected to the guide groove 703, and then the connecting bolt 707 is inserted into the through hole 706 and screwed into the connecting thread groove 702, thereby connecting the positioning block 704 and the U-shaped block 701.

[0030] Furthermore, the docking mechanism also includes an outer ring assembly 8, which includes an upper outer ring 801 fixedly connected to the end of the chassis 401, a lower outer ring 802 fixedly connected to the end of the docking plate 13, and an annular ramp 803 formed on the outer surface of the upper outer ring 801 and the outer surface of the lower outer ring 802.

[0031] Furthermore, the lifting assembly 4 includes a chassis 401, which is located above the adsorption assembly 9. A fixed sleeve 402 is fixedly connected to the top of the chassis 401. A groove 403 is provided on the side of the fixed sleeve 402. A lifting threaded rod 404 is rotatably disposed inside the fixed sleeve 402. A lifting block 405 is threadedly connected to the outer surface of the lifting threaded rod 404. A slider 406 is fixedly connected to the side of the lifting block 405. A motor 407 is located inside the chassis 401. The output end of the motor 407 is fixedly connected to the end of the lifting threaded rod 404. The motor 407 drives the lifting threaded rod 404 to rotate. The slider 406 and the groove 403 limit the movement of the lifting block 405, thus the rotating lifting threaded rod 404 drives the lifting block 405 to move up and down.

[0032] Furthermore, the connecting rod assembly 5 includes a push rod 501 hinged to the side of the slider 406, a protrusion 503 hinged to one end of the push rod 501, a rotating rod 502 fixedly connected to one end of the protrusion 503, and a connecting block 504 fixedly connected to one end of the rotating rod 502. The free end of the rotating rod 502 is hinged to the end of the fixed sleeve 402. The lifting block 405 is raised and lowered, thereby driving the push rod 501 to deflect, thereby driving the rotating rod 502 to rotate, thereby achieving the clamping of the clamping assembly 7. The connecting block 504 can be connected to the fixed frame 601 by mounting bolts.

[0033] When the adsorption component 9 completes the pre-adhesion, the motor 407 drives the lifting threaded rod 404 to rotate, thereby causing the lifting block 405 to rise. At the same time, the slider 406 slides along the inside of the groove 403, which in turn causes the push rod 501 to deflect, thereby causing the rotating rod 502 to move closer together. This allows the locking block 708 to contact and press against the annular ramp 803, causing the locking block 708 to move along the upright rod 602 and press against the top spring 604. Using the deformation force of the top spring 604, the upper and lower locking blocks 708 stably clamp the upper outer ring 801 and the lower outer ring 802, thus forming a secondary docking fixation. When separation is required later, the adsorption component 9 no longer adsorbs, the motor 407 reverses, thereby causing the lifting block 405 to move down, which in turn causes the push rod 501 to deflect in the opposite direction, thereby causing the rotating rod 502 to open, allowing the locking block 708 to leave the outer ring component 8. At this time, the drone can fly away.

[0034] Furthermore, the adsorption component 9 includes a docking block 901, which is fixedly connected to the end face of the chassis 401. An electromagnet 902 is fixedly installed inside the docking block 901. The docking block 901 is composed of a conical block and a circular base fixedly connected to the end of the conical block. A docking groove 903 is opened on the end face of the docking plate 13. An iron sleeve 904 is fixedly installed inside the docking groove 903, and the inner contour of the iron sleeve 904 matches the outer contour of the docking block 901. By inserting the docking block 901 into the docking groove 903, the chassis 401 and the docking plate 13 can be quickly docked and pre-docked for positioning. At the same time, the electromagnet 902 is energized to generate magnetism, thereby adsorbing the iron sleeve 904, so that the docking block 901 can be stably inserted into the docking groove 903, which also facilitates the subsequent clamping of the clamping component 7.

[0035] Example 2: Based on Example 1, Example 2 further discloses that the connecting component 10 includes a fixing post 1001, which is fixedly connected to the bottom of the lifting component 4. One end of the fixing post 1001 is fixedly connected to an insert block 1002. The insert block 1002 is composed of a conical block 10021 and a square block 10022 fixedly connected to one end of the conical block 10021. A connecting circular block 1003 is fixedly connected to the middle of the detection device body 11. A slot 1004 adapted to the insert block 1002 is provided in the middle of the connecting circular block 1003. The connecting sleeve 1010 is threaded to the outer surface of the connecting block 1003. An annular groove 1006 is formed at the end of the connecting sleeve 1010. A limiting groove 1007 is formed on one side of the annular groove 1006. An inner groove 1008 is formed on the inner wall of the limiting groove 1007. A rotating sleeve 1005 is fitted onto the outside of the connecting sleeve 1010. A limiting block 1009 is fixedly connected to the inner wall of the rotating sleeve 1005. A rubber protrusion is fixedly connected to the side of the limiting block 1009. By moving the rotating sleeve 1005 upwards, the limiting block 1009 is inserted into the limiting groove. 1007, so that the rubber protrusion engages with the inner groove 1008, wherein the outer contour of the limiting block 1009 matches the inner contour of the limiting groove 1007. Then, rotate the rotating sleeve 1005, which drives the connecting sleeve 1010 to rotate, causing the connecting sleeve 1010 to separate from the connecting round block 1003. Then, move the detection device body 11 downward to separate the insert 1002 from the slot 1004. During installation, insert the insert 1002 into the slot 1004, and then rotate the rotating sleeve 1005 in the opposite direction to separate the connecting sleeve 1002 from the slot 1004. 10 can be screwed into the connecting round block 1003. The design of the conical block 10021 facilitates quick docking of the insert block 1002 and the slot 1004. The square block 10022 facilitates the limiting of the slot 1004, thereby preventing the detection device body 11 from rotating after installation. When the rotating sleeve 1005 is lowered, the limiting block 1009 separates from the limiting groove 1007. The limiting block 1009 is located inside the annular groove 1006. At this time, even if the rotating sleeve 1010 is rotated, the connecting sleeve 1005 will not rotate, which has good anti-collision performance.

[0036] Furthermore, the docking mechanism also includes multiple visual cameras 3 and multiple ranging radars installed at the bottom of the fixed circular platform 1, a connecting plate 2 fixedly connected to the top of the fixed circular platform 1, and a Hall sensor 12 installed inside the docking plate 13. The connecting plate 2 is used to connect with the drone, such as the bracket preset on the drone. The visual cameras 3 and ranging radars can easily transmit the scene information around the detection device body 11, thereby assisting the detection device body 11 to accurately drop and connect, and also making it easier to judge the clamping status of the clamping component 7. The Hall sensor 12 can transmit the magnetic force of the electromagnet 902 approaching the iron sleeve 904. When the magnetic force is at its maximum or no longer changing, that is, when the docking block 901 and the docking groove 903 are inserted, it can help determine whether the adsorption component 9 has been adsorbed. The chassis 401 is equipped with a battery to power the motor 407 and the electromagnet 902. The Hall sensor 12 is powered by the battery inside the detection device body 11.

[0037] A method for an insulator testing device based on a drone, comprising the following specific steps: Step 1: Take off with the drone carrying the docking mechanism and its detection device body 11. Use the visual camera 3 and ranging radar to identify the scene until the drone is at the landing position, and then perform the landing operation of the detection device body 11. Step 2: The lifting component 4 drives the connecting rod component 5 to break open, so that the locking block 708 no longer locks the outer ring component 8, and the electromagnet 902 no longer attracts the iron sleeve 904. Then the drone flies away and is detected by the detection device body 11. Step 3: The drone flies to the detection device body 11 and uses the docking block 901 to mate with the docking groove 903. At the same time, the electromagnet 902 attracts the iron sleeve 904. The change in magnetic force is transmitted through the Hall sensor 12. Then, the lifting component 4 drives the connecting rod component 5 to close, so that the clamping component 7 clamps the outer ring component 8. The clamping information is transmitted by the vision camera 3. Then, the drone carries the detection device body 11 away.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
