Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) inspection technology, and in particular to a power line patrol UAV. Background Technology

[0002] Power line patrol drones can efficiently and safely conduct comprehensive inspections of high-voltage transmission lines. They can quickly traverse complex terrain and perform missions even in adverse weather conditions, not only reducing the risks of manual inspections but also significantly improving inspection efficiency, promptly detecting and warning of line faults, and ensuring the stable operation of the power system.

[0003] Many drones used for inspection have emerged in the existing technology. For example, a protection device for drone high-voltage line inspection with patent application number 202421339795.4 is described. The device uses rubber airbag 1 set in the lower protective ring tube, rubber airbag 2 in the vertical tube, and rubber airbag 3 in the upper protective ring tube to work together. When the inspection drone loses control and falls, the rubber airbag 2 around it will provide 360-degree protection for the inspection drone, thereby preventing damage to the main body of the inspection drone and its fan blade mechanism.

[0004] However, this type of drone, like most traditional drones, has a common drawback: its limited battery life. When performing inspection tasks, drones have to frequently stop to recharge, often needing to return to base for charging. This forces the continuity of inspection operations to be interrupted, and each charging session means a halt in the workflow. This situation severely reduces the inspection efficiency of drones.

[0030] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship of "upper", "lower", "left", "right", "inner", "outer" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0032] In addition, it should be further pointed out that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] As shown in Figures 1 to 7 The embodiment provides an electric power cruise unmanned aerial vehicle, which comprises an unmanned aerial vehicle body, the unmanned aerial vehicle body is provided with an auxiliary inspection assembly, the auxiliary cruise assembly comprises a visible light camera 13 and an infrared camera 14 carried on the bottom of the unmanned aerial vehicle body; further comprising a shell 1 detachably connected to the top of the unmanned aerial vehicle body, a power supply 2 is arranged in the shell 1, and no less than one set of power taking device 3 is further arranged, the power taking device 3 is connected to the upper portion of the shell 1 in a lifting manner, the power taking device 3 comprises two mutually hinged power taking coils 31, and a control assembly for controlling the two power taking coils 31 to close to form an induced current to realize power taking, further, the power taking coils 31 are coated with insulating materials, meanwhile, the shell is made of flame-retardant and high-temperature-resistant polycarbonate material, so as to ensure the reliability of power supply; further comprising a photovoltaic panel 4, the photovoltaic panel 4 is connected to the upper portion of the shell 1, and the power taking device 3, the photovoltaic panel 4 and the power supply are electrically connected with an inspection system 5 through wires, and a rectifier filter module is arranged between the power taking device 3 and the power supply 2, the current in the line is converted into smooth and stable direct current through a rectifier bridge through the rectifier filter module, so as to meet the energy demand of the power supply 2, and ensure the charging safety and stability of the inspection unmanned aerial vehicle.

[0034] Due to the limited endurance, the unmanned aerial vehicle has to be frequently stopped for charging when performing the inspection task. At present, the unmanned aerial vehicle is highly dependent on specific charging facilities when stopping for charging, so it often needs to return to the base for charging operation. In this way, not only the coverage range of the unmanned aerial vehicle inspection operation is greatly limited, and the unmanned aerial vehicle cannot work in more areas, but also the continuity of the inspection operation is forced to be interrupted, and each charging means that the work process is stagnant. This condition seriously reduces the inspection efficiency of the unmanned aerial vehicle, and it is difficult to meet the efficient and comprehensive inspection demand.

[0035] Based on the above problems, the power taker 3 is used to cooperate with the photovoltaic panel 4 to improve the endurance of the power taker 3, so that the power taker 3 can realize the function of uninterrupted cruising in the non-fault condition. The unmanned aerial vehicle for inspection is free from the limitation of relying on specific charging facilities, and can ensure continuous and stable operation of the unmanned aerial vehicle during the inspection process, so as to ensure the coherence and integrity of data acquisition. When performing real-time state monitoring, the cruising unmanned aerial vehicle can continuously collect data during the power taking process, timely find potential problems of the line, avoid missing of data loss or abnormal conditions caused by interruption of charging, and improve the accuracy and reliability of the inspection work.

[0036] When the power taker 3 is used for power taking, the power taker 3 is gradually moved close to the line by controlling the unmanned aerial vehicle for inspection. When reaching the appropriate position, the two power taking coils 31 are opened by means of the control assembly, and then are buckled on the line. After the buckling is completed, the two power taking coils 31 are closed again by means of the control assembly, and the power taking operation is started.

[0037] This inductive power taking mode utilizes the magnetic field around the power transmission line, and through the principle of electromagnetic induction, since there is an alternating current on the power transmission line, a magnetic field will be generated around the line. The power taking coil 31 will generate an induced electromotive force in the changing magnetic field, and obtain alternating current energy. Then, through the rectification and filtering module, a stable power is obtained.

[0038] The power taker 3 is small in size and convenient to install on the unmanned aerial vehicle for inspection, and does not occupy too much space. It can realize real-time and continuous power supply, so that the unmanned aerial vehicle can be charged simultaneously during the execution of the inspection task, effectively solves the problem of endurance of the unmanned aerial vehicle, and greatly improves the efficiency and continuity of the inspection work.

[0039] Reference Figure 5 and Figure 6 In some embodiments, the power taker 3 is fixedly connected with a base 6 at the bottom, the base 6 is in a "T" shape structure, and the base 6 is slidably arranged in the lifting channel 9 formed in the shell 1. A rotatable threaded rod 8 is arranged in the shell 1, a threaded hole 7 is formed in the bottom of the base 6, and the threaded rod 8 is threadedly connected with the threaded hole 7, so that when the threaded rod 8 rotates, the base 6 is driven to fit in the lifting channel 9 and can move vertically in the lifting channel 9.

[0040] In order to drive the threaded rod 8 to rotate, a rotating motor can be assembled at the bottom of the threaded rod 8 in this embodiment. When the rotating motor is started to drive the threaded rod 8 to rotate, since the base 6 is fitted to the inner wall of the lifting channel 9 around, under the guidance of the lifting channel 9, the rotation of the threaded rod 8 is converted into the linear movement of the base 6. The stable lifting of the power taker 3 can be realized.

[0041] The lifting mode is used to realize the lifting of the power collector 3. On the one hand, the power collector 3 can be hidden in the lifting channel 9 during the cruising of the unmanned aerial vehicle, so as to avoid the bumping and collision of the power collector 3 and the contact with external objects, thereby avoiding the damage caused by the bumping and collision of the power collector 3. On the other hand, when the power collector 3 is hidden in the lifting channel 9, the overall shape of the unmanned aerial vehicle is more streamlined, and the wind resistance coefficient is greatly reduced. The reduction of the wind resistance can reduce the energy loss during the flight of the unmanned aerial vehicle, so that the unmanned aerial vehicle can fly a longer distance, and the cruising range is significantly improved.

[0042] Reference Figure 6 In some embodiments, in order to improve the power collection efficiency, two groups of power collectors 3 are symmetrically arranged on the shell 1. Further, if one group of power collectors 3 fails during use, the other group can also work normally, thereby maintaining the normal operation of the unmanned aerial vehicle.

[0043] In order to realize the synchronous lifting of the two groups of power collectors 3, the bottom of the threaded rod 8 corresponding to each power collector 3 is fixed with a belt pulley 10. The two belt pulleys 10 are connected by a transmission belt 11. The lower side of one of the belt pulleys 10 is connected with a driving motor 12.

[0044] When the driving motor 12 is started, one of the belt pulleys 10 is rotated. Due to the connection of the transmission belt 11, the rotary motion can be transmitted to the other belt pulley 10. The synchronous rotation of the two belt pulleys 10 drives the threaded rods 8 above them to rotate, thereby realizing the synchronous lifting of the two power collectors 3 in the lifting channel 9. The synchronous lifting design makes the relative position and attitude of the two power collectors 3 and the line consistent, optimizes the power collection effect, and avoids the instability of power collection caused by different lifting.

[0045] In some embodiments, the control mechanism includes an electric push rod 32 hinged to the base 6. A protruding ear 33 is fixed outside the power collection coil 31 above. The other end of the electric push rod 32 is hinged to the protruding ear 33. The protruding ear 33 provides a fulcrum for the electric push rod 32. When the electric push rod 32 receives a control signal and is started to retract, the power collection coil 31 above rotates around the hinge point, thereby realizing the opening of the power collection coil 31. When the electric push rod 32 is elongated, the power collection coil 31 above rotates around the hinge point, thereby realizing the closing of the power collection coil 31.

[0046] In some embodiments, the inspection system 5 comprises a processor 51, which is peripherally equipped with the power supply 2 and an image acquisition module 52, a storage module, and a communication module 54. The visible light camera 13 and the infrared camera 14 are both electrically connected to the image acquisition module 52. The power supply 2 provides energy for other modules, ensuring that the entire inspection system 5 can continuously operate. During the inspection, the visible light camera 13 captures the images of the inspection area and transmits them to the image acquisition module 52; the infrared camera 14 detects temperature abnormalities of equipment and other conditions by using the infrared radiation characteristics of objects; the collected information is saved by the storage module 53; the communication module 54 serves as a bridge for communication with the outside world and is responsible for transmitting the collected information to the remote control center or other equipment. These modules are all coordinated and controlled by the processor 51.

[0047] In some embodiments, a top cover 15 is fixed above the shell 1, the top cover 15 is in a trapezoidal structure, and the photovoltaic panels 4 are arranged on both sides and the top of the top cover 15. These photovoltaic panels 4 are designed as available auxiliary energy sources to provide additional power support for the power supply 2, improving its continuous operation ability in different environments.

[0048] In some embodiments, a support 16 is fixed at the bottom of the shell 1, and the support 16 is fixedly connected with a carrier 17 fixed at the top of the unmanned aerial vehicle body through a bolt 18. This design facilitates the quick disassembly of the unmanned aerial vehicle body and the shell 1 in actual application scenarios. When the power extractor 3 and the components inside the shell 1 need to be maintained and repaired, the operator only needs to use a tool to unscrew the connecting bolt 18 to quickly separate the unmanned aerial vehicle body and the shell 1, improving the efficiency of maintenance work and reducing the downtime of the equipment.

[0049] In some embodiments, a light supplement lamp 19 is arranged inside the shell 1, and the light supplement lamp 19 is electrically connected with the processor 51 and the power supply 2. The light supplement lamp 19 automatically starts to effectively illuminate the inspection area at night. Especially in the environment of power plants with complex lines, the light supplement lamp 19 can clearly present the details, helping the inspection personnel to accurately judge whether the line has abnormalities such as wire wear, component loosening, and heating hazards.

[0050] In some embodiments, an ultrasonic alarm 20 is also arranged in the shell 1, and the ultrasonic alarm 20 is electrically connected with the processor 51. In some environments, bird groups often choose to perch on high-voltage transmission lines, and the jumping or moving of the birds on the lines can also cause problems such as line wear, poor contact, etc., which poses a certain threat to the safety of the lines. At the same time, the bird groups can also hinder the unmanned aerial vehicle through the power receiver 3. In view of this problem, the image acquisition module 52 and the processor 51 cooperate with each other to monitor the surrounding environment in real time, and when it is detected that the bird groups affect the lines, the ultrasonic alarm 20 sends instructions to drive the birds away without harming the birds.

[0051] Although the specific embodiments of the utility model have been described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
