Technical Field

[0001] The present invention relates to the technical field of unmanned inspection, and in particular to a long-flight unmanned aerial vehicle inspection device. Background Art

[0002] With the development of science and technology, more and more industries are beginning to choose to use drone inspections instead of traditional manual inspections. Among them, power grid personnel will use drones to efficiently and quickly inspect overhead transmission circuits, especially in some areas with uneven terrain, which has great advantages over manual inspections.

[0003] However, most existing drones are limited by factors such as single fuselage and small capacity. The small number of internal batteries leads to a short overall flight time, generally between 20 minutes and 1 hour, which is undoubtedly insufficient for line inspection tasks that require long-term flight. In addition, existing drones are not easy to store, resulting in them occupying a large space when stored. To this end, we propose a long-flight drone inspection device. Summary of the invention

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 5 The present invention provides a technical solution: a long-flight UAV inspection device, comprising two symmetrically arranged cylindrical battery racks 1, the top two sides of the cylindrical battery racks 1 are respectively connected to the driving motor 9 through folding arms, such as Figure 1 As shown, the folding arm includes a connection seat 11 symmetrically arranged on the top side of the cylindrical battery rack 1, and a cantilever 10 is rotatably installed in each connection seat 11. The connection seat 11 and the cantilever 10 are fixed by a lock, so the cantilever 10 can rotate around the connection seat 11. When in use, it is rotated to a horizontal position and then fixed to the connection seat 11 by the lock. When not in use, Figure 4As shown, the lock is opened, and the cantilever 10 can be folded to the side of the cylindrical battery rack 1;

[0026] When in use, the driving motor 9 is specifically installed on the free end of the cantilever 10, and a folding blade 8 is arranged on the rotating shaft of the driving motor 9, and the driving motor 9 is a brushless motor.

[0027] The two cylindrical battery racks 1 in the present application are connected by a folding frame, and the distance between the two cylindrical battery racks 1 changes as the folding frame is extended or retracted, that is, the two cylindrical battery racks 1 can be connected like Figure 5 It can be folded and stored, and the cantilever 10 can also be stored, so that the volume of the entire drone inspection equipment is reduced, making it more convenient to carry and store. A cylindrical battery 5 is provided in each cylindrical battery rack 1, and the cylindrical battery 5 supplies power to the drive motor 9. It should be noted that cylindrical batteries 5 are provided in both cylindrical battery racks 1. The cylindrical battery rack 1 is large in size, which makes the cylindrical batteries 5 installed therein also large in size. Therefore, after installing the cylindrical batteries 5 in the cylindrical battery rack, not only can the weight of the drone be increased, making its flight stable, but the two larger cylindrical batteries 5 can carry more battery capacity, which increases the hovering time.

[0028] At the same time, the cylindrical battery rack 1 has low flight resistance, and the cantilever and folding blades are both arranged on the top of the cylindrical battery rack 1. After the cylindrical battery is installed in the cylindrical battery rack 1, the center of gravity of the drone is below the folding blade, so the flight is stable.

[0029] Of course, the drone inspection equipment must include a camera, which can be detachably mounted below the two cylindrical battery racks 1. Figure 1 and Figure 3 As shown, a controller is provided on the side of one of the cylindrical battery racks 1, and the controller is respectively connected to the drive motor 9, the cylindrical battery 5, and the shooting device. The controller is installed in a control box 12, and the control box 12 is provided on the side of the cylindrical battery rack 1;

[0030] The control box is porous, which is convenient for heat dissipation of the controller. The controller is specifically a PCB control motherboard. The control box is also equipped with a wireless transceiver and a positioning module connected to the controller. The wireless transceiver supports 4G, 5G, 6G and other wireless signals, while the positioning module supports Beidou positioning. When in use, the operator holds the remote control, and the remote control is connected to the drone inspection equipment through a wireless signal. The operator can control the drone inspection equipment to perform hovering inspections.

[0031] In actual use, the number of cylindrical batteries 5 can be carried according to the task requirements. If the cylindrical battery 5 of the first inspection is almost exhausted, the cylindrical battery 5 can be replaced by controlling the drone to return. Therefore, the cylindrical battery 5 here needs to be detachable. Figure 2As shown, the top of the cylindrical battery rack 1 is connected to the outside, and the cylindrical battery 5 is detachably installed in the cylindrical battery rack 1. The top of the cylindrical battery rack 1 and the cylindrical battery 5 are connected by a lock, so that the cylindrical battery 5 is fixed in the cylindrical battery rack 1. A handle 7 is also provided on the top of the cylindrical battery 5 for convenient lifting. When replacing the cylindrical battery 5, only the handle 7 is needed;

[0032] like Figure 2 As shown, there is a connector 19 at the bottom of the inner cavity of the cylindrical battery rack 1, and the connector 19 is connected to the controller through a wire. An interface corresponding to the connector 19 is provided at the bottom of the cylindrical battery 5. When the cylindrical battery 5 is placed in the cylindrical battery rack 1, the connector 19 is docked in the interface. When a new cylindrical battery 5 is replaced, since the size of the cylindrical battery 5 matches the size of the inner cavity of the cylindrical battery rack 1, the cylindrical battery 5 can be automatically positioned when placed in, and automatic docking of the connector and the structure can be achieved.

[0033] like Figure 1 and Figure 2 As shown, the folding frame is an important supporting structure of the two cylindrical battery racks 1, and there are two of them, which are symmetrically distributed on both sides of the top of the cylindrical battery rack 1. Each folding frame includes a first support arm 4 and a second support arm 16, which are cross-arranged and rotatably connected in the middle;

[0034] The tops of the first support arm 4 and the second support arm 16 are respectively rotatably connected to the top side of the cylindrical battery rack 1, and the other ends of the first support arm 4 and the second support arm 16 are connected to the side of the cylindrical battery rack 1 through a guide mechanism. Figure 1 As shown, in order to enhance the stability of the folding frames on both sides, a connecting rod 6 is provided in the middle of the two folding frames, so that the two ends of the connecting rod 6 are rotatably connected to the middle of the first support arm 4 and the second support arm 16;

[0035] like Figure 1 and Figure 5 As shown, the guide mechanism includes a guide rail 3 arranged on the side of the cylindrical battery rack 1, and the guide rail 3 is parallel to the axis of the cylindrical battery rack 1; the bottoms of the first support arm 4 and the second support arm 16 are respectively rotatably connected to the slider 17, and the slider 17 is respectively slidably installed on the guide rail 3, and the slider 17 is provided with a locking member for positioning it, and the locking member includes a connecting buckle or a locking bolt;

[0036] Specifically, the first support arm 4 and the second support arm 16 form an "X"-shaped frame. When the angle between the first support arm 4 and the second support arm 16 increases, the "X"-shaped frame drives the two cylindrical battery racks 1 to move closer to each other for storage. When the angle between the first support arm 4 and the second support arm 16 decreases, the "X"-shaped frame drives the two cylindrical battery racks 1 to move away from each other for extension. When the two cylindrical battery racks 1 are fully opened, the slider can be fixed by a locking piece, and then the cantilever 10 can be folded to release the drone.

[0037] Furthermore, the present application also proposes a specific structure of the shooting device, which includes a U-shaped bracket 15, the U-shaped bracket 15 is opened downward, and a telescopic mechanism 13 connected to the controller is installed on the top of the U-shaped bracket 15, and the telescopic mechanism 13 is an electric telescopic rod. Figure 1 and Figure 2 As shown, the U-shaped bracket 15 is placed between two cylindrical battery racks 1, and the two ends of the U-shaped bracket 15 are detachably connected to the cylindrical battery racks 1, and the two ends of the U-shaped bracket 15 extend horizontally. When in use, the end of the U-shaped bracket 15 can be connected to the cylindrical battery rack 1 by a locking knob.

[0038] After opening the two cylindrical battery racks 1, the U-shaped bracket 15 is installed. The installed U-shaped bracket 15 can strengthen the strength between the bottoms of the two cylindrical battery racks 1. The telescopic end of the telescopic mechanism 13 faces downward, and is detachably connected to the shooting stabilization frame 14 at the bottom of the telescopic end. A camera 20 is provided on the free end of the shooting stabilization frame 14. When shooting, the camera 20 is connected to the controller and can be lowered to the bottom of the cylindrical battery rack 1 under the drive of the telescopic mechanism 13 so as to obtain a better field of view. When not in use, the telescopic mechanism 13 drives the camera 20 to retract and place it in the U-shaped bracket 15. Two supporting legs 2 are symmetrically installed at the bottom of each cylindrical battery rack 1. The U-shaped bracket 15 is located above the supporting legs 2. Retracting the camera 20 can prevent it from contacting the ground when landing.

[0039] Finally, at least two openings 18 are symmetrically provided on the surface of the cylindrical battery rack 1 . The provided openings can not only reduce the weight of the cylindrical battery rack 1 , but also dissipate heat and cool the cylindrical batteries 5 .

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
