Description

Technical Field

[0001] The utility model relates to the technical field of measuring electrical variables, in particular to a contact-type electrical testing device for unmanned aerial vehicles. Background Art

[0002] In the inspection and maintenance of overhead power transmission and distribution lines, testing the electricity is the first step of the inspection. The line inspection and maintenance work can only be started after the line is confirmed to be free of voltage. The traditional method of testing the electricity is for operators to climb up the pole tower and use a telescopic contact test pen to test the line at a safe distance. After determining that the line is free of voltage, the grounding wire can be installed. The traditional process of climbing the pole tower to test the electricity is risky and there are hidden dangers such as falling and electric shock.

[0003] With the development of technology, it is now possible to use drones to move the tester to high lines for testing electricity. The main structure of the existing drone testing device is to install the tester under the drone. In order to ensure that the tester can be smoothly connected to the line, the joint of the tester needs to be much lower than the drone. Therefore, the length of the joint is relatively long. When the drone completes the test, the joint will first connect with the ground, which is inconvenient for the drone to land. If the length of the joint is reduced, the drone is at risk of touching the line, which is inconvenient for the operation of the drone at high altitudes. Utility Model Content

[0027] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0028] like Figures 1 to 7 As shown, the utility model proposes a contact-type electrical testing device for a UAV, comprising a UAV body 1, a tilt bracket 2 is installed below the UAV body 1, the number of the tilt brackets 2 is two, a mounting plate 3 is detachably mounted on the two tilt brackets 2, ball joints 4 are installed on both sides of the mounting plate 3, a buckle 5 is installed on the movable end of the ball joint 4, the buckle 5 is buckled on the surface of the tilt bracket 2, and a tightening bolt for fixing the angle of the ball joint 4 is installed on the ball joint 4. Due to the mobility of the ball joint 4, it can be ensured that the buckle 5 can be buckled on the tilt brackets 2 with different inclinations, so as to adapt to various UAVs and facilitate installation.

[0029] A mounting groove is provided on the lower surface of the mounting plate 3, a locking block 6 is installed inside the mounting groove, and a locking head 7 is fixedly connected to the lower surface of the locking block 6. In order to ensure that the locking block 6 is fixed in the mounting groove, a through hole communicating with the inside of the mounting groove is provided on the front of the mounting plate 3, a T-shaped plug 8 is plugged into the inside of the through hole, and a locking opening is provided on the surface of the locking block 6. The locking block 6 can be fixed by inserting the T-shaped plug 8 into the locking opening. A circular groove is provided on the front of the mounting plate 3, and the circular groove and the T-shaped plug 8 are mutually connected. A tension spring 9 is fixedly connected to the opposite side, and the upper surface of the locking block 6 and the lower surface of the T-shaped plug block 8 are both arc-shaped. When the locking block 6 is inserted into the installation groove, the arc surface of the locking block 6 will overlap the arc surface of the T-shaped plug block 8. At this time, the T-shaped plug block 8 will be subjected to force to stretch the tension spring 9. When the locking mouth on the locking block 6 moves to the T-shaped plug block 8, the tension of the tension spring 9 will pull the T-shaped plug block 8 to insert into the locking mouth, thereby automatically fixing the locking block 6. The locking block 6 can be removed by actively pulling the T-shaped plug block 8 out of the locking mouth.

[0030] The lower surface of the locking head 7 is fixedly connected with a connecting rod, and a tester body 10 is installed on the lower surface of the connecting rod. The tester body 10 is installed with a non-contact test signal collection antenna. The test process is to first perform a non-contact test and then perform a contact test when there is no electricity. The double test mutual verification method is used to detect whether the high-voltage line is energized, which has high reliability. The tester body 10 is installed with a flashing light and a horn for reminder, and a communication antenna is installed to ensure that the detection data is transmitted to the receiver connected to the tester body 10. The detection end of the tester body 10 is installed with a lap rod 11, and the lap rod 11 is composed of a plurality of swing rods 12. The upper surface of the swing rod 12 is fixedly connected with a T-shaped rod 13, and the lower surface of the swing rod 12 is provided with a swinging opening. The setting of the swinging opening facilitates the swinging of the T-shaped rod 13, and the inner side wall of the swinging opening is provided with a sliding groove. The T-shaped rod 13 is located inside the sliding groove of the upper swing rod 12. The T-shaped rod 13 can slide in the sliding groove, and both ends of the T-shaped rod 13 are provided with T-shaped grooves. The inner wall of the T-shaped groove is slidably connected with a T-shaped plug rod 14. The end face of the T-shaped plug rod 14 is hemispherical. The T-shaped plug rod 14 and the opposite surface of the T-slot are fixedly connected with a connecting spring 15, and a positioning groove adapted to the T-shaped plug rod 14 is provided at the top of the sliding groove.

[0031] When conducting a live circuit detection in the vertical direction, the drone body 1 drives the electroscope body 10 to move to the top of the line, and adjusts the position of the overlapping rod 11 to overlap with the line to conduct a live detection. In the specific use process, the drone body 1 drives the overlapping rod 11 to move to the side of the line, and the drone body 1 drives the overlapping rod 11 to move in the direction of the line. After the overlapping rod 11 overlaps with the line, the drone body 1 continues to drive the overlapping rod 11 to move a distance in the direction of the line. At this time, the swing rod 12 on the overlapping rod 11 will rotate due to the obstruction of the line, so that the overlapping rod 11 is bent. At this time, the swing rod 12 located above will overlap with the top of the line, so that the coverage of the overlapping rod 11 and the line is increased, thereby ensuring the detection of the line by the overlapping rod 11.

[0032] After the detection is completed, the UAV body 1 flies down and stops. In order to prevent the UAV body 1 from being too close to the line during the detection, the vertical length of the lap rod 11 is much larger than the UAV. When falling, the lap rod 11 first contacts the ground. At this time, the bottom swing rod 12 is subjected to force. Since the T-shaped rod 13 on the swing rod 12 can swing in the slide groove, the bottom swing rod 12 will be tilted by force. Similarly, the lap rod 11 will contact the ground in a bent state, thereby facilitating the landing of the UAV body 1 and avoiding damage to the detection site.

[0033] When the left and right distances of the lines are too close, it is inconvenient to overlap the overlapping rod 11 from the top. We fix the concave seat 16 at the bottom of the connecting rod, and the electroscope body 10 is rotatably installed inside the concave seat 16. Therefore, before the drone body 1 takes off, we can rotate the electroscope body 10 in advance to make the overlapping rod 11 horizontal and push the swing rod 12. The swing rod 12 drives the T-shaped rod 13 to move upward. When the T-shaped plug 14 moves to the positioning groove, the elastic force of the connecting spring 15 will push the T-shaped plug 14 to insert into the positioning groove, and the upper and lower swing rods 12 are overlapped. At this time, the swing rod 12 cannot rotate, thereby assembling multiple swing rods 12 into a whole, avoiding the swing of the swing rod 12 when the overlapping rod 11 is in a horizontal state. At the same time, in order to avoid the overlapping of the overlapping rod 11 with the ground during landing, the horizontal plane where the bottom of the uppermost swing rod 12 of the electroscope body 10 is located is higher than the horizontal plane where the bottom of the inclined bracket 2 is located.

[0034] Both sides of the electroscope body 10 are fixedly connected with a rotating shaft 17, and both sides of the concave seat 16 are provided with a rotating hole. The surface of the rotating shaft 17 is rotatably connected to the inner wall of the rotating hole. In order to ensure that the position of the electroscope body 10 is fixed after it is rotated to a horizontal state, a turntable 18 is fixed on the end face of the rotating shaft 17, and the side of the turntable 18 is fixedly connected to the mounting box 22. A T-shaped movable rod 19 that passes through the turntable 18 is slidably installed inside the mounting box 22. The end face of the T-shaped movable rod 19 is spherical, and the opposite surface of the T-shaped movable rod 19 and the mounting box 22 is fixedly connected with a reset spring 20, and the side of the mounting box 22 is threadedly connected with a positioning bolt 21. The side of the concave seat 16 is provided with two limit grooves with an angle of 90 degrees. 19 is inserted into the inner part of the limiting groove. When the positioning bolt 21 is away from the T-shaped movable rod 19, the reset spring 20 is in a normal state. When the electroscope body 10 is rotated, the rotating shaft 17 will drive the turntable 18 to rotate. At this time, the installation box 22 drives the T-shaped movable rod 19 to rotate. When the T-shaped movable rod 19 is out of the limiting groove, the T-shaped movable rod 19 will push the reset spring 20 for extrusion. When the T-shaped movable rod 19 moves to another limiting groove, the T-shaped movable rod 19 is inserted into the limiting groove under the elastic force of the reset spring 20 to complete the positioning. At this time, the angle adjustment of the electroscope body 10 is also completed. Rotating the positioning bolt 21 to block the T-shaped movable rod 19 can avoid the movement of the T-shaped movable rod 19, thereby fixing the angle of the electroscope body 10.
