Description

Technical Field

[0002] The drone carries an electrical testing device and approaches and touches the overhead power lines. It uses the tester to identify whether the line is out of power. After the test is completed, the drone returns to the ground. Compared with traditional manual electrical testing methods, drone electrical testing greatly shortens the operation time.

[0003] Therefore, when the existing drone electrical testing equipment is actually used, the bracket used by the electrical testing equipment is large and heavy, which is not easy to carry and will increase the physical energy consumption of the staff. At the same time, there will be strong airflow at high altitudes, causing the electrical testing equipment to shake on the cable, resulting in errors in the electrical testing results of the electrical testing equipment. Moreover, since the cable is not a straight line, it is impossible to determine whether the electrical testing equipment is in stable contact with the cable, resulting in the inability to determine the accuracy of the electrical testing results of the electrical testing equipment.

[0016] Compared with the prior art, the present invention provides a transmission line power testing device based on a drone, which has the following beneficial effects:

[0017] 1. The invention can achieve lightweight equipment by setting up an electric test frame, which is convenient for workers to carry and assemble. The center of gravity of the electric test frame can be adjusted according to the size of the wind force through the balancing mechanism. When the wind force increases, the wire rope will automatically extend, and the tension of the wire rope and the wind force will reach a new balance state, so that the electric tester can remain stable under different wind conditions, increase the stability of the center of gravity of the electric tester, and prevent the electric test frame from tipping over due to wind force.

[0018] 2. The invention can detect whether there is a detection error in the electroscope by setting up a detection mechanism:

[0019] In the first case, when the tester detects that the cable is not charged, and the cable is actually not charged, the magnetic switch is started, the current inside the lithium battery is amplified by the current amplifier, and a loop is formed through the cable, and the electrical appliance generates a path signal. At this time, the current formed by the cable loop will be detected by the tester, indicating that the test data of the tester is accurate and the cable is not charged;

[0020] In the second case, when the tester detects that the cable is not energized due to shaking or position displacement during the detection process, but the cable is actually energized, the magnetic switch is started at this time, and the strong current causes the fuse tube to break. The electrical appliance does not send a path signal, which means that the cable is energized. At this time, the inspection drone returns with the test frame, and the staff pulls out the broken fuse tube from the top of the fuse box and replaces it with a new one. The inspection drone can be driven to place the test frame on the outside of the cable for detection again. Repeat the above steps until the first case occurs and the cable test is completed.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a transmission line power testing device based on a drone.

[0040] Embodiment 1, as Figure 1-Figure 7 As shown, a transmission line electricity testing device based on a drone includes an inspection drone 1 and an electric tester 4. An insulating rope 2 is suspended at the bottom of the inspection drone 1, a safety buckle 3 is suspended at the bottom of the insulating rope 2, and the electric tester 4 is suspended at the bottom of the safety buckle 3;

[0041] The test frame 5 is convenient for fixing the tester 4 on the outside of the cable. The test frame 5 includes two fixing frames 9. A fixing plate 8 is fixedly connected to the opposite side of the two fixing frames 9. The output end of the tester 4 is clamped inside the fixing plate 8. Two mounting plates 10 are fixedly connected to the opposite side of the two fixing frames 9. The two mounting plates 10 are symmetrically arranged. An inclined frame 11 is movably clamped at the bottom of the two mounting plates 10. The tops of the two mounting plates 10 are provided with a weight reduction groove 44.

[0042] A clamping plate 15 is slidably connected to one side of the fixing plate 8, and two clamping springs 16 are fixedly connected to one side of the fixing plate 8. One end of the two clamping springs 16 is fixedly connected to one side of the inner wall of the fixing plate 8. A clamping hole 17 is provided on the top of the fixing plate 8 and the clamping plate 15. A clamping slot 18 is provided on the detection end of the electroscope 4. The detection end of the electroscope 4 passes through the fixing plate 8 through the clamping hole 17, and the clamping hole 17 inside the clamping plate 15 is clamped with the clamping slot 18.

[0043] Two insertion holes 13 are provided on the top of the mounting plate 10, and the internal threads of the insertion holes 13 are screwed with fixing nuts 12. A groove 14 is provided on the top of the inclined frame 11, and the inclined frame 11 is movably inserted into the inside of the adjacent mounting plate 10, and the bottom of the fixing nut 12 abuts against the groove 14 on the top of the inclined frame 11.

[0044] The above-mentioned structure is set up to facilitate placing the electroscope 4 on the top of the cable, and at the same time improve portability. Specifically, when it is necessary to test the cable, the clamping plate 15 is pressed to one side of the inner wall of the fixing plate 8. At this time, the fixing plate 8 is aligned with the clamping hole 17 on the top of the clamping plate 15, and the detection end of the electroscope 4 can be inserted into the inside of the fixing plate 8 and passed out from the bottom of the fixing plate 8. At this time, the clamping plate 15 is released, and the two clamping springs 16 are extended to make the clamping hole 17 inside the clamping plate 15 engage with the clamping groove 18 outside the electroscope 4, and the electroscope 4 is fixed on the top of the fixing plate 8. After completion, the two inclined frames are put together. 11 is inserted into the corresponding socket 13, and the knob fixing nut 12 is turned to make the bottom of the fixing nut 12 abut against the groove 14, and the inclined frame 11 is fixed to the inside of the mounting plate 10. Then the safety buckle 3 is opened, and the tester 4 is hung at the bottom of the safety buckle 3. At this time, the tester 4 cannot be separated from the inside of the safety buckle 3, thereby improving the safety performance of the tester 4. After all is completed, the inspection drone 1 can be started to take off and the fixing frame 9 can be hung on the outside of the cable. The two inclined frames 11 are arranged in an eight-shaped shape on the outside of the tester frame 5, which can improve the positioning of the inspection drone 1.

[0045] Embodiment 2, as Figure 8-Figure 12As shown, a transmission line electricity testing device based on a drone is combined with the embodiment 1, and a balancing mechanism 6 is used to keep the center of gravity of the electricity testing frame 5 stable. The balancing mechanism 6 includes a balancing shell 19 that is clamped in the weight reduction groove 44. The top of the balancing shell 19 is rotatably connected to a cup fan 20. The bottom of the cup fan 20 is fixedly connected to a second damping ring 30. The outer damping rotatable connection of the second damping ring 30 is connected to a first damping ring 29. The bottom of the first damping ring 29 is fixedly connected to a rotating shaft 35. The outer part of the rotating shaft 35 is wound with a steel wire rope 25. The bottom of the steel wire rope 25 is fixedly connected to a counterweight 26. The outer part of the balancing shell 19 is rotatably connected to a rotating rod 22. The rotating rod 22 is used to limit the rotation of the cup fan 20.

[0046] The balancing mechanism 6 also includes a fixing ring 27 fixedly connected to the inner wall of the balancing shell 19, a volute spring 28 is fixedly connected inside the fixing ring 27, one end of the volute spring 28 is fixedly connected to the outside of the first damping ring 29, a limiting plate 36 is fixedly connected to the inner wall of the balancing shell 19, a nut slide 38 is slidably connected inside the limiting plate 36, a limiting rod 37 is fixedly connected inside the limiting plate 36, the nut slide 38 is slidably connected to the outside of the limiting rod 37, a threaded groove 39 is provided on the outside of the rotating shaft 35, one end of the nut slide 38 is slidably connected to the inside of the threaded groove 39, and the top of the nut slide 38 abuts against the outside of the wire rope 25.

[0047] By setting the above structure, the center of gravity of the electrometer frame 5 can be adjusted according to the size of the wind force, so as to avoid the electrometer 4 shaking on the top of the cable and causing detection errors. Specifically, when the second damping ring 30 rotates and drives the first damping ring 29 to rotate, part of the force driving the first damping ring 29 to rotate will be accumulated inside the volute spring 28:

[0048] When the rotation damping force of the first damping ring 29 and the second damping ring 30 is greater than the compression force of the rotated spiral spring 28, the second damping ring 30 will continue to drive the first damping ring 29 to rotate;

[0049] When the rotation damping force of the first damping ring 29 and the second damping ring 30 is equal to the compression force of the rotated spiral spring 28, the second damping ring 30 rotates and the first damping ring 29 is in a stationary state;

[0050] When the rotation damping force of the first damping ring 29 and the second damping ring 30 is less than the compression force of the spiral spring 28 after rotation, the second damping ring 30 cannot drive the first damping ring 29 to rotate, and the spiral spring 28 returns to its original position and drives the first damping ring 29 to rotate in the opposite direction, until the rotation damping force of the first damping ring 29 and the second damping ring 30 is equal to the compression force of the spiral spring 28 after rotation, or the force accumulated in the spiral spring 28 is completely released, and the spiral spring 28 stops driving the first damping ring 29 to rotate;

[0051] It is worth mentioning that the rotation speed of the second damping ring 30 is proportional to the damping force between the second damping ring 30 and the first damping ring 29. The faster the rotation speed of the second damping ring 30 is, the greater the damping force between the second damping ring 30 and the first damping ring 29 is.

[0052] More specifically, when there is wind, the cup fan 20 rotates, and the rotation of the cup fan 20 drives the second damping ring 30 to rotate, and the rotation of the second damping ring 30 drives the first damping ring 29 to damp the rotation, and the rotation of the first damping ring 29 drives the rotating shaft 35 to rotate, and the rotation of the rotating shaft 35 drives the nut slide plate 38 to slide inside the thread groove 39, and at the same time, the nut slide plate 38 slides inside the limiting plate 36, and the nut slide plate 38 slides outside the limiting rod 37, and the nut slide plate 38 moves up and down inside the balance shell 19, driving the steel wire rope 25 wound on the outside of the rotating shaft 35 to gradually separate from the rotating shaft 35 from the lower end, so that the bottom end of the steel wire rope 25 extends to the bottom of the balance shell 19, and drives the counterweight block 26 to move downward through the steel wire rope 25, thereby lowering the center of gravity of the test stand 5 and improving the wind resistance of the tester 4 and the test stand 5;

[0053] On the contrary, when the wind force is small, resulting in the rotational damping force of the first damping ring 29 and the second damping ring 30 being smaller than the compression force of the rotated spiral spring 28, the second damping ring 30 cannot drive the first damping ring 29 to rotate, and at the same time the spiral spring 28 returns and drives the first damping ring 29 to rotate in the opposite direction, winding part of the wire rope 25 extending to the bottom of the balance shell 19 around the outside of the rotating shaft 35 and driving the counterweight 26 close to the balance shell 19, thereby maintaining the wind resistance of the electroscope 4 and the electroscope frame 5 while reducing the risk of contact with other objects or birds, thereby improving safety in use.

[0054] Furthermore, in the above scheme, when the wind force increases, the wire rope 25 will automatically extend, and the tension of the wire rope 25 and the wind force reach a new equilibrium state, so that the electroscope 4 can remain stable under different wind conditions, increase the center of gravity stability of the electroscope 4, and prevent the electroscope frame 5 from tipping over due to wind force. This adaptive ability enables the electroscope 4 to work accurately even in a strong wind environment, which greatly reduces the risk of electrical accidents caused by the tipping over of the electroscope frame 5, ensures the safety of the operator, and avoids misjudgment of the cable live status due to wind. At the same time, the wire rope 25 can produce greater elastic deformation under the action of wind, which helps to disperse the energy impact brought by the wind. Furthermore, the operator does not need to manually adjust the state of the electroscope 4 according to the wind force, but only needs to focus on the detection work itself, which greatly simplifies the operation process and improves work efficiency.

[0055] The outside of the balance shell 19 is fixedly connected with a rotating clamp 40, one side of the rotating clamp 40 is rotatably connected with a rotating rod 22, the inside of the rotating clamp 40 is fixedly connected with a resist spring 41, the left side of the resist spring 41 is fixedly connected with a resist block 42, the resist block 42 is slidably connected to the inside of the rotating clamp 40, the outside of the rotating rod 22 is provided with a resist groove 43, the resist groove 43 is adapted to the resist block 42, the top of the rotating rod 22 is fixedly connected with a meshing tooth 23, the outside of the cup fan 20 is fixedly sleeved with a gear ring 24, the meshing tooth 23 is adapted to the gear ring 24, and the bottom of the rotating rod 22 is arranged in an arc shape;

[0056] By setting the above structure, the test stand 5 can be balanced after being placed on the top of the cable, which is convenient for early placement. Specifically, when the test stand 5 is not hung on the top of the cable, the meshing teeth 23 and the gear ring 24 are in a meshing state, which prevents the cup fan 20 from rotating and extending the counterweight 26, which increases the difficulty of hanging the test stand 5 on the top of the cable.

[0057] More specifically, when the test stand 5 is placed on the cable, the outer portion of the cable touches the bottom of the two rotating rods 22, and the rotating rods 22 rotate inside the rotating clamp 40, separating the meshing teeth 23 from the gear ring 24, so that the cup fan 20 can rotate, and the test stand 5 is balanced;

[0058] It is worth mentioning that during the rotation of the rotating rod 22, the resist spring 41 stretches, and one end of the resist block 42 is stuck inside the resist groove 43, preventing the rotating rod 22 from rotating to mesh the meshing teeth 23 and the gear ring 24 together again, causing the test stand 5 to shake more severely due to wind.

[0059] The balance shell 19 is internally rotatably connected with a double-threaded rod 31, and the external threads of the double-threaded rod 31 are screwed with a nut slider 32. The opposite sides of the two nut sliders 32 are fixedly connected with a damping half ring 33. The cup fan 20 is externally fixedly sleeved with a sliding ring 34, and the damping half ring 33 slides on the outside of the sliding ring 34.

[0060] By setting up the above-mentioned structure, the rotation speed of the cup fan 20 can be controlled. Specifically, the double-threaded rod 31 is rotated, and the rotation of the double-threaded rod 31 drives the two nut sliders 32 to move relative to each other, thereby controlling the damping rotational force of the two damping half rings 33 on the sliding ring 34, and the rotation speed of the cup fan 20 under the same wind force conditions can be controlled.

[0061] A mounting groove 45 is formed on the top of the mounting plate 10 , and a plurality of protrusions 46 are fixedly connected to the top of the mounting plate 10 . A protrusion 47 is fixedly connected to the outside of the balancing shell 19 , and the protrusion 47 is clamped in the inside of the mounting groove 45 through the plurality of protrusions 46 .

[0062] By setting the above structure, the balancing shell 19 can be clamped on the top of the mounting plate 10. Specifically, the bottom of the balancing shell 19 is inserted into the weight reduction groove 44, and the protruding plate 47 enters the interior of the mounting groove 45 and is fixed by the protruding block 46.

[0063] Embodiment 3, as Figure 13-Figure 16 As shown, a transmission line electricity testing device based on a drone is combined with the basis of Example 1 and Example 2. A detection mechanism 7 is clamped on the top of the fixing plate 8. The detection mechanism 7 is used to detect whether the test result of the electric tester 4 is correct.

A lithium battery 54, a current amplifier 55, a magnetic switch 56, a fuse box 53 and an electrical appliance 49 are fixedly installed on the bottom of the inner wall of the detection shell 48.

[0064] Both ends of the bottom of the detection shell 48 are fixedly connected with a telescopic sleeve 51, the interior of the telescopic sleeve 51 is fixedly connected with a telescopic spring 59, the bottom of the telescopic spring 59 is fixedly connected with a telescopic contact 52, the telescopic contact 52 is slidably connected to the inside of the telescopic sleeve 51, the first wire 57 and the second wire 58 are extended to the inside of the adjacent telescopic sleeve 51, one end of the first wire 57 and the second wire 58 are electrically connected to the top of the adjacent telescopic contact 52, and the bottoms of the two telescopic contacts 52 are both in contact with the outside of the cable;

[0065] A detection groove 60 is provided on the top of the fixed plate 8, a retaining ring 62 is fixedly connected to the inside of the detection groove 60, a detection block 61 is fixedly connected to the bottom of the detection shell 48, an annular groove 21 is provided on the outside of the detection block 61, and the detection block 61 is clamped in the detection groove 60 by the retaining ring 62 and the annular groove 21.

[0066] By setting up the above-mentioned structure, it is possible to detect whether there is a detection error in the tester 4. Specifically, the detection block 61 is inserted into the detection groove 60, and the detection shell 48 is fixedly clamped on the top of the fixed plate 8 by the cooperation of the clamping ring 62 and the ring groove 21. When the tester frame 5 is placed on the top of the cable, the bottoms of the two telescopic contacts 52 are both in contact with the outside of the cable.

[0067] When the tester 4 detects that the cable is not energized, there are two situations:

[0068] In the first case, when the tester 4 detects that the cable is not energized and the cable is actually not energized, the magnetically controlled switch 56 is started, the current inside the lithium battery 54 is amplified by the current amplifier 55, and a loop is formed through the cable, and the electrical appliance 49 is used to generate a path signal. At this time, the current in the loop formed by the cable will be detected by the tester 4, indicating that the inspection data of the tester 4 is accurate and the cable is not energized.

[0069] In the second case, when the tester 4 detects that the cable is not energized due to shaking or position displacement during the detection process, but the cable is actually energized, the magnetic switch 56 is started at this time, and the strong current causes the fuse tube 50 to break. The electrical appliance 49 does not send a path signal, which means that the cable is energized. At this time, the inspection drone 1 returns with the tester rack 5, and the staff pulls out the broken fuse tube 50 from the top of the fuse box 53 and replaces it with a new fuse tube 50. The inspection drone 1 can be driven to place the tester rack 5 on the outside of the cable for detection again. The above steps are repeated until the first case occurs, and the cable test is completed.

[0070] More specifically, since the direction of wind blowing is uncontrollable and the wind does not necessarily blow in only one direction when blowing, when the wind blows the test frame 5, the test frame 5 will shake in the direction of its own width, causing one side of the test frame 5 to lift up. Since the tester 4 is clamped on the top of the fixing plate 8, the lifting of one side of the test frame 5 indirectly drives the detection end of the tester 4 to separate from the outside of the cable, thereby affecting the detection of the tester 4. However, since the bottoms of the two telescopic contacts 52 are much lower than the detection end of the tester 4, and the telescopic contacts 52 are both slidably connected to the inside of the telescopic sleeve 51, when the detection end of the tester 4 abuts against the outside of the cable, the top of the telescopic contact 52 slides inside the telescopic sleeve 51, and when one side of the test frame 5 is lifted, the telescopic contact 52 slides out from the inside of the telescopic sleeve 51 and can still maintain abutment with the outside of the cable, so that when the wind force causes the detection result of the tester 4 to be inaccurate, the detection mechanism 7 cooperates with the tester 4 to obtain an accurate result.

[0071] Working principle of the present invention: when it is necessary to test the electricity of the cable, press the clamping plate 15 to one side of the inner wall of the fixing plate 8, at this time, the fixing plate 8 is aligned with the clamping hole 17 on the top of the clamping plate 15, and the detection end of the electroscope 4 can be inserted into the inside of the fixing plate 8 and pass through the bottom of the fixing plate 8. At this time, release the clamping plate 15, and the two clamping springs 16 extend, so that the clamping hole 17 inside the clamping plate 15 is clamped with the clamping groove 18 outside the electroscope 4, and the electroscope 4 is fixed on the top of the fixing plate 8. After completion, the two inclined frames 11 are inserted into the corresponding jacks 13. At this time, the knob fixes the nut 12 so that the bottom of the fixing nut 12 abuts against the groove 14, and the inclined frame 11 is fixed inside the mounting plate 10, and then the safety buckle 3 is opened, and the electroscope 4 is hung at the bottom of the safety buckle 3. At this time, the electroscope 4 cannot be separated from the inside of the safety buckle 3, thereby improving the safety performance of the electroscope 4 in testing electricity. After all is completed, the inspection drone 1 can be started to take off and the fixing frame 9 can be hung on the outside of the cable. The two inclined frames 11 are arranged in an eight-shaped shape on the outside of the electroscope frame 5, which can improve the positioning of the inspection drone 1;

[0072] When testing the electricity of the cable in a place with strong wind or rapid wind change, the bottom of the balance shell 19 is inserted into the inside of the weight reduction groove 44, and the convex plate 47 enters the inside of the installation groove 45, and the convex plate 47 is fixed by the convex block 46 to complete the installation of the balance shell 19. At this time, the inspection drone 1 is used to place the electricity test frame 5 on the top of the cable. In the process of placing the electricity test frame 5 on the cable, the outside of the cable touches the bottom of the two rotating rods 22. At this time, the rotating rod 22 rotates inside the rotating clamp 40, separating the meshing teeth 23 from the gear ring 24, so that the cup fan 20 can rotate, and the electricity test frame 5 is balanced and controlled;

[0073] When the wind is strong, the cup fan 20 rotates, and the rotation of the cup fan 20 drives the second damping ring 30 to rotate, and the rotation of the second damping ring 30 drives the first damping ring 29 to rotate, and the rotation of the first damping ring 29 drives the rotating shaft 35 to rotate, and the rotation of the rotating shaft 35 drives the nut slide plate 38 to slide inside the thread groove 39, and at the same time, the nut slide plate 38 slides inside the limit plate 36, and the nut slide plate 38 slides outside the limit rod 37, and the nut slide plate 38 moves up and down inside the balance shell 19, driving the steel wire rope 25 wound on the outside of the rotating shaft 35 to gradually separate from the rotating shaft 35 from the bottom end, so that the bottom end of the steel wire rope 25 extends to the bottom of the balance shell 19, and drives the counterweight block 26 to move downward through the steel wire rope 25, thereby lowering the center of gravity of the test stand 5 and improving the wind resistance of the tester 4 and the test stand 5;

[0074] On the contrary, when the wind force is small, resulting in the rotation damping force of the first damping ring 29 and the second damping ring 30 being smaller than the compression force of the rotated volute spring 28, the second damping ring 30 cannot drive the first damping ring 29 to rotate, and at the same time the volute spring 28 returns and drives the first damping ring 29 to rotate in the opposite direction, winding the portion of the steel wire rope 25 extending to the bottom of the balancing shell 19 around the outside of the rotating shaft 35 and driving the counterweight 26 close to the balancing shell 19, while maintaining the wind resistance of the electroscope 4 and the electroscope frame 5, the risk of contact with other objects or birds can be reduced, thereby improving the safety of use;

[0075] When the detection result of the electroscope 4 needs to be further confirmed, the detection block 61 is inserted into the detection groove 60, and the detection shell 48 is fixedly clamped on the top of the fixing plate 8 by the cooperation of the clamp ring 62 and the ring groove 21, and the installation of the detection mechanism 7 is completed. At this time, the inspection drone 1 is used to place the test frame 5 on the top of the cable, and the bottoms of the two telescopic contacts 52 are both in contact with the outside of the cable. When the electroscope 4 detects that the cable is not charged, there are two situations:

[0076] In the first case, when the tester 4 detects that the cable is not charged, and the cable is actually not charged, the magnetic switch 56 is started, the current inside the lithium battery 54 is amplified by the current amplifier 55, and forms a loop through the cable, and the electrical appliance 49 generates a path signal. At this time, the current formed by the cable loop will be detected by the tester 4, indicating that the test data of the tester 4 is accurate and the cable is not charged;

[0077] In the second case, when the tester 4 detects that the cable is not energized due to shaking or position displacement during the detection process, but the cable is actually energized, the magnetic switch 56 is started at this time, and the strong current causes the fuse tube 50 to break. The electrical appliance 49 does not send a path signal, which means that the cable is energized. At this time, the inspection drone 1 returns with the tester rack 5, and the staff pulls out the broken fuse tube 50 from the top of the fuse box 53 and replaces it with a new fuse tube 50. The inspection drone 1 can be driven to place the tester rack 5 on the outside of the cable for detection again. The above steps are repeated until the first case occurs, and the cable test is completed.
