Description

Technical Field

[0001] The present invention relates to the technical field of electric power inspection and repair, and in particular to an unmanned aerial vehicle electric power inspection device. Background Art

[0002] The electroscope is an instrument for detecting whether an object is charged and roughly estimating the amount of charge. Most of its structures are described in the Chinese patent publication number CN107843763B entitled a multifunctional electroscope, which mainly includes an insulating rod, an electroscope body connected to the insulating rod, and a probe as a detection end of the electroscope body.

[0003] Electroscopes are often used for live detection of overhead wires. Common methods include manual detection and drone detection. Manual detection is to hold an insulating rod of sufficient length and move the probe to the wire to be detected for detection. Drone detection is to fix the insulating rod on the drone and use the drone to move the probe to the wire to be detected for detection. Since the above two detection methods are remotely operated, there is a problem of insufficient control of operating accuracy; and the existing electroscope lacks protection for the probe part, resulting in the probe often getting stuck in the wire during the actual detection process. At the same time, the existing electroscope probe part cannot be flexibly adjusted and cannot better adapt to the usage scenario, so it needs to be solved urgently. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention provides a drone electrical testing device, which mainly solves the technical problems existing in the above-mentioned background technology.

A sliding sleeve is provided on the outside of the probe, and the sliding sleeve is fixed to the electroscope body. The probe can slide freely in the sliding sleeve.

[0009] As a preferred solution of the present invention, two guide rods are provided on the mounting frame, the two guide rods are cross-distributed, and an open guide area is formed between the two guide rods, the detection area is located in the guide area, and the detection area and the guide area opening are in the same direction, and the outer ends of the two conductive wires are respectively fixed on the two guide rods.

[0010] As a preferred solution of the present invention, a quick-release plug is fixed to the handheld end of the insulating rod.

[0013] As a preferred solution of the present invention, a camera is installed on the insulating rod, and the collection direction of the camera is the direction of the opening end of the detection area.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The conductive wire forms a conductive connection with the probe through the conductive sleeve.

[0028] In order to fully understand the present invention, a detailed structure will be proposed in the following description to illustrate the technical solution proposed by the present invention. The optional embodiments of the present invention are described in detail as follows, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0029] Embodiment 1: Please refer to the attached Figure 1 To Attachment Figure 4, an unmanned aerial vehicle electrical testing device, comprising an insulating rod 10, a tester body 40 is provided at the mounting end of the insulating rod 10, a micro pressure sensor 41a and a telescopic drive device 41b are integrated inside the tester body 40, a probe 41 is connected to the output end of the telescopic drive device 41b, an angle sensor 42 is provided on one side of the tester body 40, and a mounting frame 30 for assembling the tester body 40 is also provided at the mounting end of the insulating rod 10, a conductive shield 20 is fixedly provided on the mounting frame 30, the conductive shield 20 comprises a conductive sleeve 22, the conductive sleeve 22 is sleeved on the needle head of the probe 41 on the tester body 40, so that the needle head of the probe 41 is located in the sleeve cavity of the conductive sleeve 22, and the conductive sleeve 22 forms a conductive connection with the probe 41, the conductive sleeve 22 is electrically connected to the inner end of the conductive wire 21, and the outer end of the conductive wire 21 is fixedly connected to the mounting frame 30, and the conductive wire 21 forms a detection area with an opening facing outward.

[0030] Exemplarily, in the present invention, the conductive wire 21 forms a conductive connection with the probe 41 through the conductive sleeve 22, and the conductive sleeve 22 is used to wrap the probe 41, and the conductive wire 21 is used to contact the wire instead of the traditional electrical test form of the probe 41 contacting the wire, which can avoid the problem of the probe 41 getting stuck in the wire. When in use, by operating the insulating rod 10, the conductive wire 21 is formed into a detection area and sleeved on the outer periphery of the overhead wire until the conductive wire 21 and the outer periphery of the overhead wire form abutment; because the outer end of the conductive wire 21 is fixed to the mounting frame 30, in the process of sleeved on the outer periphery of the overhead wire, the wire can also avoid the outer end of the conductive wire 21.

[0031] In specific implementation, there are many implementation methods for the conductive wire 21 to form a detection area that opens outward, such as: the conductive wire 21 can adopt a V-shaped structure, the inner end node of the V-shaped conductive wire 21 is fixed to the conductive sleeve 22, and the two outer end nodes are fixed to the mounting frame 30, and the detection area is formed by the V-shaped inner cavity; similarly, the conductive wire 21 can be a W-shaped structure or a semicircular structure; or the conductive wire 21 and the conductive sleeve 22 are an integrated structure, and the conductive sleeve 22 is formed by winding the middle part of the conductive wire 21. Of course, the conductive wire 21 can also be set to be two cross-distributed wires, the inner ends of the two conductive wires 21 are fixed to the conductive sleeve 22, and the outer ends are fixed to the mounting frame 30, and the space between the two conductive wires 21 forms an open detection area. Regardless of the implementation method, it is preferred that the detection area is an open structure, so that when wires of different diameters slide into the inner cavity of the detection area, they can contact the inner wall of the conductive wire 21, ensuring adaptability to different wire detection operations.

[0032] The angle information of the electroscope body 40 is monitored in real time by the angle sensor 42, and the data is transmitted to the flight control system of the UAV. When approaching the power transmission line, the micro pressure sensor 41a detects the contact pressure with the conductive wire 21 and transmits the signal to the telescopic drive device 41b. The telescopic drive device 41b automatically adjusts the telescopic length of the contact according to the pressure value to ensure that good electrical connection can be achieved on wires of different thicknesses and materials.

[0033] As a preferred solution of the present invention, there are two conductive threads 21, and the two conductive threads 21 cross each other.

[0034] Exemplarily, the two conductive threads 21 cross each other to ensure good conductivity.

[0035] As a preferred solution of the present invention, the open end of the detection zone is the extension direction of the installation end of the insulating rod 10. For example, when in use, it is only necessary to adjust the angle of the insulating rod 10 so that the length of the insulating rod 10 points to the wire. At this time, when the insulating rod 10 is slid along its own axial direction, the detection zone can be set on the outer periphery of the cable, which improves the convenience of device operation.

[0036] As a preferred solution of the present invention, the telescopic drive device 41b includes a micro rack 411, a micro gear 412, and a micro worm gear motor 414. The probe 41 is connected to the micro rack 411, and the micro rack 411 and the micro gear 412 are meshed with each other. The output end of the micro worm gear motor 414 is rotatably connected to the micro gear 412. The probe 41 is provided with a sleeve 413 on the outside, and the sleeve 413 is fixed to the electroscope body 40. The probe 41 can slide freely in the sleeve 413. The conductive wire 21 leaves a certain telescopic distance when installed for the probe 41 to slide. Further, the surface of the probe 41 is made of a high-density tungsten alloy, which not only has good electrical conductivity, electrical corrosion resistance, and high voltage resistance, but also has high thermal conductivity and low expansion coefficient. At the same time, it also exhibits excellent corrosion resistance and oxidation resistance, and can be oxidized at 500°C without obvious oxidation.

[0037] As a preferred solution of the present invention, two guide rods 31 are provided on the mounting frame 30, and the two guide rods 31 are cross-distributed, and an open guide area is formed between the two guide rods 31, and the detection area is located in the guide area, and the opening directions of the detection area and the guide area are consistent, so as to facilitate the judgment of the relative position between the open end of the detection area and the wire, so as to facilitate the control of the open end of the detection area to be stably sleeved on the outer periphery of the conductive wire 21, and the outer ends of the two conductive wires 21 are respectively fixed on the two guide rods 31.

[0038] As a preferred solution of the present invention, a quick-release plug 12 is fixed to the handheld end of the insulating rod 10 .

[0039] As a preferred embodiment of the present invention, Figure 4 As shown, it also includes an articulated block 60, on which a buckle seat 62 is fixed, and on which a buckle seat 62 is provided a slot 621 for engaging with the quick-release plug 12, and on which a locking knob 63 is rotatably engaged, and during the rotation process, the locking knob 63 has a locking state of pressing the quick-release plug 12 into the inner cavity of the slot 621 and an unlocking state of separating from the quick-release plug 12. In actual implementation, in order to further ensure the stable connection between the insulating rod 10 and the articulated block 60, a connecting bolt can be further provided between the buckle seat 62 and the quick-release plug 12 to serve as the last insurance for the connection of the insulating rod 10.

[0040] Specifically, the unlocked state is that the locking knob 63 is separated from the quick release plug 12, so that there is a gap between the quick release plug 12 and the locking knob 63 for the quick release plug 12 to slip out of the slot 621. The quick disassembly and assembly between the insulating rod 10 and the hinge block 60 is achieved by rotating the locking knob 63, which improves the convenience of assembling the insulating rod 10 and the drone.

[0041] For example, Figure 3 As shown, the electroscope body 40 is connected to the lower part of the UAV's carrying platform through a rotating hinge block 60. The rotating hinge block 60 allows the electroscope body 40 to rotate freely in the vertical plane, and can adjust the electroscope angle by controlling the UAV's flight position after the guide rod 31 contacts the wire and is subjected to force according to the actual direction and spatial position of the transmission line. For example, when facing a curved or inclined transmission line, the electroscope body 40 can be quickly adjusted to the optimal electroscope angle to ensure that the probe 41 is in full contact with the wire, greatly improving the accuracy and reliability of the electroscope.

[0042] Embodiment 2: As a preferred solution of the present invention, it also includes a fixing seat 50 assembled and fixed to the drone, such as Figure 3 As shown, a locking pin 51 is slidably fitted on the fixing seat 50, and a pin hole 61 which is plugged and fitted with the locking pin 51 is provided on the hinge block 60. At least two pin holes 61 are arranged at intervals, and the movement paths of all the pin holes 61 as the hinge block 60 rotates intersect with the locking pin 51. After the locking pin 51 is pulled out from the pin hole 61, the hinge block 60 is rotated to adjust the insulating rod 10 to the desired angle, and then the locking pin 51 is plugged into the pin hole 61 at the corresponding position, so as to realize rapid locking of the hinge block 60 after rotation adjustment, which has the advantage of convenient and quick adjustment.

[0043] For example, due to the complexity of overhead wire lines, there are often situations where multiple strands of wire are distributed in parallel and at intervals. Specifically, there are multiple strands of wire distributed horizontally and at intervals, multiple strands of wire are distributed vertically and at intervals, or there is disordered and chaotic distribution. Under different distribution conditions of multiple strands of wire, it is obviously not possible to use a single fixed angle between the insulating rod 10 and the drone. For example, if multiple strands of wire are distributed horizontally and the insulating rod 10 is installed horizontally on the drone, the wires located on the inside cannot be detected. Similarly, if multiple strands of wire are distributed vertically and the insulating rod 10 is installed vertically on the drone, the wires located on the inside cannot be detected. In addition, even if the insulating rod 10 is installed on the drone in an inclined manner, interference with adjacent wires will occur. Therefore, in view of the drone detection method, the connection between the insulating rod 10 and the drone is innovatively improved in this application. Specifically, such as Figure 2 and Figure 3 As shown, the handheld end of the insulating rod 10 can be rotated and adjusted around a horizontal rotation axis, and the horizontal rotation axis is perpendicular to the axis of the insulating rod 10, thereby adjusting the installation angle of the insulating rod 10 on the drone.

[0044] Since the insulating rod 10 can be adjusted to a specific angle relative to the drone, the insulating rod 10 can avoid other wires when the drone is hoisted, so that the tester body 40 arranged at the installation end of the insulating rod 10 does not need to be restricted to the traditional contact tester with a probe 41. Specifically, a non-contact tester can be arranged at the installation end of the insulating rod 10 to achieve accurate live testing of the wire.

[0045] Specifically, non-contact electroscopes mainly include two types of electroscopes based on the electric field induction principle and the electromagnetic induction principle.

[0046] The principle of electric field induction is: when there is a charged body or voltage source nearby, an electric field will be generated. The non-contact electroscope is equipped with highly sensitive electric field sensors, which can sense the changes in this electric field and convert them into measurable signals.

[0047] The principle of electromagnetic induction is: when an alternating current passes through a charged body, an alternating magnetic field is generated around it. If a non-contact electroscope is equipped with an induction coil, when it is close to this alternating magnetic field, according to Faraday's law of electromagnetic induction (where is the induced electromotive force, is the number of coil turns, is the change in magnetic flux, and is the change in time), an induced electromotive force will be generated in the induction coil. Electroscopes that use the principle of electromagnetic induction are mainly used to detect the magnetic field generated by alternating current, so as to determine whether an object carries an alternating current. It is very effective for detecting whether AC high-voltage equipment is charged. The specific induction principle of the non-contact electroscope can be determined according to actual needs.

[0048] Embodiment 3: As a preferred embodiment of the present invention, Figure 5 As shown, a camera 11 is installed on the insulating rod 10, and the collection direction of the camera 11 is the direction of the opening end of the detection area; it is convenient to judge the relative position between the opening end of the detection area and the wire, so as to control the opening end of the detection area to be stably sleeved on the outer periphery of the wire.

[0049] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
