Description
Technical Field
[0001] The utility model relates to the technical field of transmission line maintenance, in particular to a safety connecting rod for an unmanned aerial vehicle used in a transmission line. Background Art
[0002] Overhead transmission lines are an important way for power transmission in the power industry, which is directly related to the economic growth of the whole country and people's normal work and life. The safe and stable operation of transmission lines directly affects the provision of highly reliable and stable electric energy in the power system. Therefore, regular and effective inspection and maintenance of transmission lines have become an important task in the power industry. The methods of manual or vehicle-borne equipment-assisted inspection are restricted due to the fact that most high-voltage transmission lines pass through complex geographical environments such as rivers, lakes or virgin forests, and they have high labor intensity, low precision, blind areas and potential safety hazards.
[0003] An unmanned aerial vehicle, abbreviated as "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self-provided program control device. UAVs have the characteristics of small size, light weight, low cost, flexible operation and high safety, and are widely used in fields such as aerial photography, detection, search and rescue, and resource exploration. It has been technically feasible to use UAVs to inspect power lines, and it has practical and realistic significance to promote the work of UAV aerial patrol of transmission lines. UAV power line patrol comprehensively checks the various equipment conditions of lines and electric towers at a relatively fast speed. At the same time, the precision instruments carried can detect deep-seated line faults and hidden faults, and the data is returned in time and the problems are processed in real time, providing an important guarantee for the safe and efficient operation of the power grid.
[0004] At present, when overhauling overhead transmission lines, UAVs need to carry some equipment to perform some operations on the overhead transmission lines in the air, such as hanging and removing grounding wires, repairing wires, etc. However, according to the safety regulations, when UAVs operate on overhead transmission lines, they need to keep a certain safety distance from the conductors, and this safety distance is determined according to the voltage level of the conductors. The higher the voltage level, the longer the required safety distance.
[0005] When the existing UAVs are used to overhaul overhead transmission lines, the equipment for overhaul is suspended under the UAV by ropes, and the UAV flies with the equipment for overhaul to the overhead transmission line to be overhauled for operation. This method has the following disadvantages:
[0006] (1) When the equipment for overhaul is fixed to the lower end of the UAV by a rope, the equipment is easy to shake, making it difficult to be in place or perform fine operations on the conductors to be overhauled.
[0007] (2) The shaking during the flight of the UAV is likely to cause the equipment for overhaul to collide with the conductors or the iron tower, resulting in damage to the equipment for overhaul.
[0008] (3) It is necessary to change the length of the rope according to different voltage levels.
[0009] (4) When the UAV lands, the rope is easily caught by the UAV propeller, which is inconvenient to handle.
[0010] In view of this, it is necessary to develop a safe connecting rod for UAVs used in transmission lines that can solve the above problems. Utility Model Content

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0044] The following further describes the present utility model in detail with reference to the drawings and embodiments:
[0045] As Figure 1 shown, a safety connecting rod for an unmanned aerial vehicle used in a transmission line includes a transverse support rod 2 installed between two legs 1-1 at the bottom of a load unmanned aerial vehicle 1, a connecting rod rotatably connected to the lower end of the transverse support rod 2, and a device 4 for inspecting a transmission line installed at the bottom end of the connecting rod; the connecting rod includes a plurality of rigid standard sections 3 connected end to end; and each two standard sections 3 are rotatably connected unidirectionally.
[0046] Specifically, the load unmanned aerial vehicle 1 can be selected from the DJI M300 and M600 series. A transverse support rod 2 is installed between two legs 1-1 at the bottom of the load unmanned aerial vehicle 1. A connecting rod formed by unidirectionally rotatably connecting a plurality of rigid standard sections 3 is connected to the lower part of the transverse support rod 2. A hook for inspecting a transmission line or an actuator for maintaining a transmission line is installed at the end of the connecting rod. The two standard sections 3 can be rotatably connected unidirectionally around a steel ball pin 5 connecting them.
[0047] As Figure 7 shown, the steel ball pin 5, also called a ball quick-release pin, is a connecting piece commonly used in mechanical equipment and industrial production. It has the characteristics of convenient disassembly and reliable connection. One end of the steel ball pin 5 is a circular handle, and the other end is provided with a popped steel ball, which is convenient for operation and has reliable locking.
[0048] Since the connecting rod formed by unidirectionally rotatably connecting a plurality of rigid standard sections 3 is a rigid connection, it can accurately position the device 4 installed at the end of the connecting rod.
[0049] Since the connecting rod formed by the one-way winding connection of several rigid standard sections 3 is a rigid connection, the load drone 1 can carry the device 4 through the safety connecting rod without causing excessive shaking in the air, and will not damage the device 4 or the transmission line.
[0050] Since the connecting rod is formed by the one-way winding connection of several rigid standard sections 3, the connecting rod can be freely combined and connected according to needs to meet the requirements of different voltage levels. For example, according to the safety regulations, when the voltage level is low, the load drone 1 needs to maintain a shorter safety distance from the conductor when operating on the overhead transmission line, and the number of standard sections 3 connected end to end is relatively small; when the voltage level is high, the load drone 1 needs to maintain a longer safety distance from the conductor when operating on the overhead transmission line, and the number of standard sections 3 connected end to end is relatively large.
[0051] Since the connecting rod is formed by the one-way winding connection of several rigid standard sections 3, when the load drone 1 lands with the connecting rod, the connecting rod can be folded or laid flat on the ground without affecting the load drone 1.
[0052] Furthermore, as Figure 1-2 shown, the transverse support rod 2 includes a cross beam 2-3, two hoop clamps 2-2 are respectively arranged at both ends of the cross beam 2-3, and a first standard connector A2-1 is arranged in the middle of the cross beam 2-3; the two hoop clamps 2-2 are respectively fixed on the legs 1-1 on both sides of the load drone 1.
[0053] Furthermore, as Figure 1-2 shown, the two hoop clamps 2-2 can adjust the tightness.
[0054] Furthermore, as Figure 1-2 shown, the cross beam 2-3 is long strip-shaped, which is convenient for installation.
[0055] Furthermore, as Figure 1-2 shown, the first standard connector A2-1 is fixed in the middle of the cross beam 2-3 by screws. The structure of the first standard connector A2-1 is as Figure 5 shown.
[0056] Furthermore, as Figure 1 、 3 、4 shown, the standard section 3 includes a fiberglass rod 3-2, a first standard connector B3-1 is arranged at the top of the fiberglass rod 3-2; a second standard connector A3-3 is arranged at the bottom of the fiberglass rod 3-2. The structure of the first standard connector B3-1 is as Figure 6 shown.
[0057] Furthermore, as Figure 1 、 3, as shown in Figures 4, 5, and 6, the first standard connector B3-1 at the top of the fiberglass rod 3-2 can be combined with the first standard connector A2-1 on the transverse support rod 2 through the steel ball pin 5 to form a hinge, and the connecting rod can rotate unidirectionally around the steel ball pin 5.
[0058] Further, as Figure 4 , 5 shown, the first standard connector A2-1 and the second standard connector A3-3 have the same structure and size; similarly, the second standard connector A3-3 at the bottom of the fiberglass rod 3-2 and the second standard connector B of the next standard section are combined through the steel ball pin 5 to form a hinge, and the next standard section can rotate unidirectionally around the steel ball pin 5, and so on.
[0059] Further, as Figure 1 , 3 , 4 shown, a first screw hole for installing the first standard connector B3-1 is provided at the top of the fiberglass rod 3-2; a second screw hole for installing the second standard connector A3-3 is provided at the bottom of the fiberglass rod 3-2. The first standard connector B3-1 is fastened to the top of the fiberglass rod 3-2 through a screw passing through the screw hole, and the second standard connector A3-3 is fastened to the bottom of the fiberglass rod 3-2 through a screw passing through the screw hole.
[0060] Further, the device is a hook or an actuator for maintaining a transmission line.
[0061] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
