The current unmanned aerial vehicle is limited by the size of the volume, the capacity of the battery installed inside is limited, the overall endurance time is short, and the charging frequency is high. For dam slope inspection, especially for dam slope inspection in high mountain and valley areas, due to the long flight route and inspection cycle of the unmanned aerial vehicle inspection task and the large inspection area, a plurality of unmanned aerial vehicles are generally required to cooperate in the inspection to simplify the inspection process. The operation mode of the unmanned aerial vehicle hangar is generally to recall the unmanned aerial vehicle with insufficient endurance and charge it to continue the inspection task.

[0003] At present, the unmanned aerial vehicle hangar for dam slope inspection task generally recalls the inspection unmanned aerial vehicle for charging when the endurance is insufficient, to supplement the endurance. However, due to the problems of long flight route and inspection cycle and large inspection area of dam slope inspection in high mountain and valley areas, if the unmanned aerial vehicle is recalled and charged multiple times with a long interval, the inspection cycle may be further prolonged, and even after multiple recalls, the data collected by the same unmanned aerial vehicle may be difficult to fuse or have large data changes, resulting in inaccurate collected data. At the same time, multiple recalls for charging will result in a high proportion of time of the unmanned aerial vehicle in the hangar and non-use state, and more unmanned aerial vehicle equipment is required to complete the inspection of the dam slope in the high mountain and valley area, which results in a high construction cost of the dam slope inspection unmanned aerial vehicle hangar.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0045] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0046] For the convenience of description, spatial relative terms can be used in the specification to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both up and down positions. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the specification are interpreted accordingly.

[0047] As shown in Figures 2 to 7 In some exemplary embodiments of the present application, a first aspect provides a UAV battery replacement mechanism for replacing the battery of a UAV 10, the UAV including a main body 11 and a battery 12 detachably connected, which mainly comprises: a battery replacement channel 20, a mechanical arm 30, a temporary storage battery library 40 and a charged battery library 50. The battery replacement channel 20 comprises a first sliding structure 21 and a second sliding structure 22 which can slide relative to each other. The first sliding structure 21 is provided with a first positioning structure 211 adapted to the main body 11. The extension direction of the first sliding structure 21 is the same as that of the second sliding structure 22. The mechanical arm 30 is fixed on the second sliding structure 22 and comprises a second positioning structure 31 adapted to the battery 12. The temporary storage battery library 40 comprises a displacement structure 41 which can transfer the battery 12 to different battery replacement channels 20. The charged battery library 50 is in communication with the temporary storage battery library 40.

[0048] In this embodiment, through the arrangement of the battery replacement channel 20 and the temporary storage battery library 40, the battery 12 can be matched according to the actual power of the UAV 10 and the inspection task, the power of the battery 12 of the UAV 10 can be fully utilized, the time occupied by the charging of the battery 12 can be reduced, and the quick replacement of the battery 12 in the UAV hangar can be effectively realized, and the number of spare batteries 12 can be reduced.

[0049] Compared with the mode relying on charging operation in the related art, the battery replacing mechanism can avoid delay of the inspection task caused by too long charging time by directly replacing the battery, reduce the waiting time of the unmanned aerial vehicle 10 in a non-task state, effectively shorten the inspection cycle, and improve continuity and efficiency of the inspection task; the battery replacing mechanism realizes quick battery replacement, reduces the frequency of recalling the unmanned aerial vehicle due to insufficient endurance, and can complete the inspection task with fewer unmanned aerial vehicles, thereby reducing the number requirement of the unmanned aerial vehicle equipment and reducing the construction cost of the unmanned aerial vehicle hangar.

[0050] In a specific scenario, for example, the capacity of the battery 12 in the first unmanned aerial vehicle 10 is 60% after completing the inspection task, and the required power for the next inspection task of the first unmanned aerial vehicle 10 exceeds 60%. To avoid the risk of missing the unmanned aerial vehicle due to the inability to return, a battery 12 with sufficient power needs to be replaced. The battery 12 with a power of 60% is insufficient to support the inspection task, but it can meet the inspection task of the second unmanned aerial vehicle 10. At this time, the battery 12 can be temporarily stored, and the corresponding battery 12 with a power of 60% is replaced after the second unmanned aerial vehicle 10 returns. In this way, the inspection task of the second unmanned aerial vehicle can be met. It can be understood that the inspection work arrangement of the first unmanned aerial vehicle and the second unmanned aerial vehicle is not limited to the battery 12, and therefore, from the priority consideration of the unmanned aerial vehicle 10, multiple battery 12 replacements can be performed to meet the inspection requirements.

[0051] In addition, in the embodiment, the mechanical arm 30 is designed to realize accurate docking of the battery 12 and the unmanned aerial vehicle body 11, guarantee the stability and reliability of the battery replacement process, and enable the unmanned aerial vehicle 10 to quickly return to the inspection route after the battery 12 is replaced, thereby avoiding too long data acquisition intervals caused by multiple recalls, further preventing problems such as data fusion failure or large data changes, and improving the timeliness and consistency of the dam slope inspection data.

[0052] In combination with the communication design between the temporary battery storage 40 and the charged battery storage 50, the battery transfer function of the displacement structure 41 can realize quick transfer of the used battery 12 and automatic replenishment of the charged battery, and can realize efficient recycling of the battery without human intervention, further improve the overall operation efficiency of the unmanned aerial vehicle hangar, and reduce labor operation and management costs.

[0053] The first sliding structure 21 and the second sliding structure 22 in the battery replacing channel 20 can slide relative to each other, and in combination with the first positioning structure 211 and the second positioning structure 31, the unmanned aerial vehicle body 11 and the battery 12 are accurately matched, the unmanned aerial vehicle hangar can adapt to the environmental restrictions in complex terrains such as high mountains and gorges, effectively improve the reliability and applicability of the unmanned aerial vehicle battery replacement, and enable the unmanned aerial vehicle hangar to ensure the continuity and stability of the inspection task in a complex environment.

[0054] Through the modular design of the charging battery warehouse and the temporary battery warehouse, the battery reserve can be flexibly expanded according to the inspection task requirements, the limitation that the traditional unmanned aerial vehicle hangar cannot cope with the sudden inspection task due to the battery charging period is effectively avoided, and therefore the task flexibility of the unmanned aerial vehicle hangar is improved, and diversified inspection requirements are adapted.

[0055] In an alternative embodiment, referring to Figure 1 The main body 11 is in a strip structure, four extension arms extend to the four directions, and four paddles are attached. The end of the extension arm away from the paddle protrudes beyond the bottom of the main body 11, and the first positioning structure 211 is correspondingly provided as four insertion slots or insertion holes to adapt to the part beyond the main body 11. When the unmanned aerial vehicle hovers above the first positioning structure 211, the sensor in the battery replacement channel 20 is used for horizontal positioning, so that the unmanned aerial vehicle can accurately match the first positioning structure 211, so as to limit the circumferential degree of freedom of the unmanned aerial vehicle, thereby meeting the requirement of disassembling and assembling the battery.

[0056] The second positioning structure 31 is a clamping jaw that can adapt to the clamping position of the battery 12. Through the movement of the mechanical arm 30, the clamping of the main body 11 is released, and the battery 12 is clamped and stabilized at the same time, thereby facilitating transportation.

[0057] It should be noted that the disassembly and assembly of the battery 12 can be performed by horizontal displacement, so a complex degree of freedom mechanical arm is not required, and a simple three-degree-of-freedom mechanical arm can be used. In this way, the cost of the mechanical arm can be saved, and complex control programs can be avoided, and the structure is simple and more practical.

[0058] In some exemplary embodiments of the present application (not shown in the figure), a plurality of groups of first sliding structures 21 and second sliding structures 22 are arranged in parallel in the battery replacement channel 20. The plurality of groups of first sliding structures 21 and second sliding structures 22 are used to adapt to multiple unmanned aerial vehicles 10 for battery replacement. Such an arrangement can enable multiple unmanned aerial vehicles to be located in the same battery replacement channel 20 when they need to replace each other's batteries, and the batteries can be replaced directly by the mechanical arm 30, thereby saving battery replacement time and improving battery replacement efficiency.

[0059] It should be noted that the plurality of second sliding structures 22 can correspond to a plurality of mechanical arms 30, or the plurality of second sliding structures 22 can correspond to one mechanical arm 30, which is not limited here.

[0060] In some exemplary embodiments of the present application (not shown in the figure), a plurality of groups of first sliding structures 21 and second sliding structures 22 are arranged in a ring and array in the battery replacement channel 20, and the mechanical arm 30 is located at the center of the ring of the plurality of first sliding structures 21, or the mechanical arm 30 can be switched on adjacent second sliding structures 22.

[0061] When the unmanned aerial vehicles need to exchange power with each other, the unmanned aerial vehicles can be located in the same power exchange channel 20 and directly exchange power through the mechanical arm 30, thereby saving power exchange time and improving power exchange efficiency.

[0062] In addition, the first sliding structure 21 and the second sliding structure 22 arranged in multiple groups in a surrounding and arrayed manner can correspond to unmanned aerial vehicles 10 returning in different directions, can reduce the positioning difficulty of the unmanned aerial vehicles 10 returning, and provide a more efficient power exchange procedure.

[0063] Further, as shown in Figure 2 and Figure 3 In some exemplary embodiments of the present application, the power exchange channel 20 is multi-layered and stacked. The multi-layered and stacked power exchange channel 20 can form a complete unmanned aerial vehicle hangar, and simultaneously accommodate multiple unmanned aerial vehicles 10 for power exchange, so as to achieve the purpose of rapid battery replacement.

[0064] As shown in Figures 5 to 7 In some exemplary embodiments of the present application, the first sliding structure 21 is a linear sliding rail, and the second sliding structure 22 is a linear sliding rail or a moving platform.

[0065] The linear sliding rail is arranged to determine the sliding direction of the first sliding structure 21 and is not easy to deviate, which is beneficial to the positioning of the unmanned aerial vehicle 10 and facilitates accurate disassembly and assembly of the battery 12.

[0066] In a specific embodiment, the linear sliding rail is arranged to slide by using a sliding rail and a driving member 212, and the driving member 212 is specifically a transmission belt, which drives the linear sliding rail to displace. Such a transmission mode is mature and convenient, has high precision, is easy to maintain, and is suitable for the arrangement of the unmanned aerial vehicle hangar.

[0067] In some other exemplary embodiments of the present application (not shown in the drawings), the first sliding structure 21 is a linear sliding rail, the second sliding structure 22 is two linear sliding rails, and the first sliding structure 21 is located between the two linear sliding rails of the second sliding structure 22. Such an arrangement can realize autonomous sliding of the mechanical arm 30 and provide active force in two directions when disassembling the battery, thereby facilitating better disassembly of the battery.

[0068] As shown in Figure 5 and Figure 6 In some exemplary embodiments of the present application, a temporary storage station 60 is arranged between the temporary battery storage 40 and the power exchange channel 20, and the temporary storage station 60 can store multiple batteries 12. The temporary storage station 60 is arranged to temporarily store the batteries 12, so that the second positioning structure 31 of the mechanical arm 30 is not occupied, thereby facilitating rapid disassembly and assembly of the batteries 12.

[0069] The temporary storage station 60 specifically includes a plurality of placement slots, which are adapted to the appearance of the battery 12. Such a design can protect the battery 12 from being moved around and facilitate the positioning of the battery 12 for the grabbing of the mechanical arm 30.

[0070] As shown in the drawings, Figures 5 to 8 In some exemplary embodiments of the present application, the temporary battery storage 40 includes a rack body 42, and the displacement structure 41 includes a first displacement member 411 and a second displacement member 412. The first displacement member 411 drives the second displacement member 412 to move in the horizontal direction, and the second displacement member 412 drives the rack body 42 to move in the vertical direction.

[0071] The first displacement member 411 and the second displacement member 412 are arranged for the movement of the rack body 42, i.e., the movement of the temporary battery storage 40. Such a design facilitates the temporary battery storage 40 to correspond to different positions of the battery replacement channel 20, and can meet the purpose of quickly responding to the transfer of the battery 12 when a large number of unmanned aerial vehicles 10 need to replace the battery 12.

[0072] Specifically, the first displacement member 411 and the second displacement member 412 are specifically sliding rails, which are correspondingly provided with sliding rail driving members, such as hydraulic cylinders or pneumatic cylinders, etc., which can drive the movement of the rack body 42.

[0073] Further, the first displacement member 411 and the second displacement member 412 are arranged in perpendicular directions to facilitate the adjustment of the position in the vertical plane.

[0074] In some exemplary embodiments of the present application (not shown in the drawings), the unmanned aerial vehicle battery replacement mechanism further includes a detection assembly arranged on the rack body 42 to detect the remaining capacity of the battery 12. The arrangement of the detection assembly is used to accurately detect the capacity of the battery 12 to prevent the change of the energy of the battery from affecting the inspection task or return.

[0075] The arrangement of the detection assembly can also calibrate the monitoring of the capacity of the battery 12 inside the unmanned aerial vehicle 10 to facilitate the judgment of whether the unmanned aerial vehicle 10 is damaged.

[0076] It can be understood that when the above-mentioned embodiments are applied, the battery replacement speed is fast, the inspection task is almost not interrupted, the inspection effect is better, and the continuity of the task is ensured. At the same time, it can adapt to intelligent task scheduling, arrange the task queue of multiple unmanned aerial vehicles, and ensure that the task is not interrupted when charging or replacing the battery. It also effectively improves the utilization rate of the battery, significantly prolongs the cruising time of the unmanned aerial vehicle, reduces the non-operation time caused by charging, and can reduce the demand for manual intervention, and enhances the automation degree of the unmanned aerial vehicle system.

[0077] In a second aspect, the embodiments of the present application provide a UAV hangar, which comprises the UAV battery replacing mechanism according to any of the above embodiments. By using the UAV battery replacing mechanism according to any of the above embodiments, the battery of the UAV 10 can be quickly replaced, and meanwhile, the intelligent battery management can be adapted, the battery capacity can be fully utilized for operation, the inventory occupation time is reduced, meanwhile, the number of batteries can be reduced to some extent, and the use cost of the UAV hangar is reduced.
