Description

Technical Field

[0001] The utility model relates to the technical field of power grid operation, maintenance and repair, and in particular to an electrometer assembly device based on an unmanned aerial vehicle. Background Art

[0002] According to relevant regulations, before carrying out maintenance work, an electric tester must be used to test the corresponding position of the maintenance line or equipment to ensure that the maintenance line or equipment is free of electricity; to prevent serious accidents such as hanging the ground wire with power on, closing the grounding knife switch, and maintenance personnel accidentally touching the live equipment. Existing electrical testing devices mainly include contact electrical testing and non-contact electrical testing.

[0003] At present, the traditional contact tester is generally used by power operators in on-site maintenance work. The maintenance personnel hold the contact tester installed with a long insulating rod or insulating rope, touch the metal probe to the tested equipment, and observe whether the tester alarms. For transmission lines with voltage levels of 110kV and above, as the voltage level increases, the height of the line tower, the size of the tower head, and the length of the insulator string are getting larger and larger, and the operation difficulty and intensity of the contact tester are getting greater and greater; for lines crossing rivers, valleys and other areas, operators cannot reach the towers, and the contact tester cannot be used normally. In recent years, many domestic power operation and maintenance departments have carried out non-contact test methods based on drones. This method mounts a non-contact test acquisition terminal on the drone, and judges whether the line is energized and whether there is induced electricity during a power outage by telemetry of the electric field distribution in the space near the conductor, and has achieved good application results. However, for non-contact test results of cross-span and dense channel lines, there will be false alarms, and other non-homologous test results are required for secondary confirmation. The use of a single non-contact electrical testing method is an indirect electrical testing method. According to regulations: when conducting indirect electrical testing, there should be at least two electrical testing indications that are not based on the same principles or are not from the same source. Therefore, a single non-contact electrical testing method does not meet the requirements.

[0004] In summary, the existing contact-type electrical testing and drone-type non-contact electrical testing have the following main shortcomings:

[0005] 1. Contact type electrical testing As the line voltage level increases and the line height increases, the difficulty and workload of electrical testing operations increase accordingly; contact type electrical testing cannot be used in operating environments where the line crosses a river or valley area or where operators cannot reach.

[0006] 2. The existing non-contact electric tester can meet the needs of electric testing in general scenarios, but it may not be able to reliably feedback the energized state of the line in areas with dense lines or crossovers, and other non-homogeneous electric testing methods are required for secondary confirmation. Moreover, non-contact electric testing is an indirect electric testing method with a single source, which does not meet the requirements of relevant regulations.

[0007] 3. A non-contact electrometer is mounted on a drone for non-contact electrical testing. Since the drone body is a metal shell and its rotor is made of carbon fiber material, which is also a conductor, it will form a large area after unfolding. These conductive components will have a great impact on the electric field measurement of the non-contact electrometer. Summary of the invention

[0008] In view of this, the utility model proposes an electrometer assembly device based on a drone, aiming to solve the problem that the existing electrometer adopts contact electrometer or non-contact electrometer, resulting in the limitation of a single electrometer method.

The yaw rod is arranged in the yaw hole in a yaw manner, and is used to adjust the angle between the yaw rod and the axial direction of the yaw hole, thereby adjusting the inclination angle of the metal electrometer rod.

[0012] Furthermore, in the above-mentioned electroscope assembly device based on a drone, a locking piece is also provided on the fixing seat, which is used to lock the deflection rod to the fixing seat after the deflection rod is swung into place.

[0013] Furthermore, in the above-mentioned drone-based electroscope assembly device, the locking part includes at least two fixing screws; wherein the fixing screws are threadedly connected to the fixing seat along the radial direction of the yaw hole, and at least two of the fixing screws are arranged at an angle, and the fixed end of the fixing screw is used to extend into the yaw hole and apply an extrusion force to the yaw rod to push the yaw rod to yaw and lock the yaw rod.

[0014] Furthermore, in the above-mentioned drone-based electroscope assembly device, a first rod clamp is provided on the fixed end of the insulating connecting rod, and the first rod clamp is detachably connected to the fixed end of the insulating connecting rod, and a quick release part is connected to the first rod clamp for being connected to the drone in a detachable manner; a second rod clamp is provided on the supporting end of the insulating connecting rod, and the second rod clamp is detachably connected to the supporting end of the insulating connecting rod, and a bottom support seat is provided on the second rod clamp for supporting the electroscope.

[0017] Furthermore, in the above-mentioned drone-based electroscope assembly device, the metal electroscope rod is a telescopic rod, which is used to adjust the relative position relationship between the metal swing chain and the electroscope.

[0018] Furthermore, in the above-mentioned electroscope assembly device based on a drone, the insulating connecting rod is a telescopic rod for adjusting the distance between the electroscope and the drone.

[0019] The utility model provides an electrician assembly device based on a drone. Through the arrangement of insulating connecting rods, the electrician can be located above the plane after the fuselage and rotor of the drone are unfolded; the metal electrician rod and the metal swing chain on the metal electrician rod contact the device to be tested, and then when the metal swing chain contacts the device to be tested, the electrician can perform contact electrician testing, and when the device is far away from the device to be tested and it is inconvenient to contact, the electrician can perform non-contact electrician testing, that is, the parameter measurement of two different sources, non-contact and contact, is integrated into a design, which can minimize the influence of the drone itself on the electric field measurement during non-contact electrician testing. The electrician assembly device based on the drone can simultaneously realize two electrician testing modes, non-contact electrician testing and contact electrician testing, and can meet the requirements of the electrician testing mode. The electrician testing results of the two electrician testing modes can be verified with each other to ensure that the electrician testing results are 100% accurate, solving the problem that the existing electrician testing adopts contact electrician testing or non-contact electrician testing, which leads to the limitation of single-mode electrician testing.

Among them, a plurality of vertically arranged threaded holes are provided on the upper left side of the fixing seat 11, which can be at least three, and the two fixing screws 121 are installed in pairs, and the fixing screws 121 press the deflection rod from top to bottom, so that the left bottom edge of the deflection rod contacts the inner wall of the fixing seat 11.

The electroscope assembly device based on the drone can simultaneously realize both non-contact electrometry and contact electrometry, and can meet the requirements of the electrometry mode. The electrometry results of these two electrometry modes can be verified with each other to ensure that the electrometry results are 100% accurate, solving the problem that the existing electroscope adopts contact electrometry or non-contact electrometry, which leads to the limitation of single-mode electrometry.
