Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicles (UAVs), and more particularly relates to a solar-powered UAV. Background Art

[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. Common civilian drones have been used to a certain extent in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief and other fields. The use and development of drones are also receiving more and more attention.

[0003] Existing drones are limited by battery capacity and can only fly for a short time. If they are required to operate for a long time, they need to replace spare batteries or use charging equipment for charging. However, spare batteries and charging equipment are inconvenient to carry. Therefore, many drones equipped with solar panels have appeared in the existing technology. They use solar energy to convert into electricity to power the battery during flight, thereby improving the endurance of the drone.

[0004] For example, patent publication number CN111071459A discloses a self-charging drone battery pack, which installs two symmetrical solar panels on the drone body. The solar panels are driven to rotate by a screw rod and an internal servo motor to achieve angle changes and improve the power generation efficiency of the solar panels.

[0005] However, the adjustment of the solar panels in the above technology is limited to the adjustment of the angle. If the drone is to be charged by solar energy, it is necessary to rotate the drone in the air to ensure that the solar panels are aligned with the sunlight. The rotation of the drone requires manual adjustment by ground operators, which is complicated to operate. In addition, the drone needs to perform other tasks and it is impossible to always maintain the optimal angle between the solar panels and the sunlight during the flight. Therefore, the solar panels cannot be used to power the drone well when the drone is flying in the air. That is, the power generation efficiency of the solar panels is low when the drone is in flight. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the utility model provides a solar-powered drone that can fully adjust the angle of the solar panel to ensure the optimal power generation efficiency of the solar panel.

[0007] To achieve the above-mentioned purpose, the present utility model provides the following technical solution: a solar-powered drone, comprising a body, a propeller provided on the body, a placement slot provided on the body, a solar panel provided in the placement slot, a tracking structure provided between the solar panel and the body, the tracking mechanism comprising a rotating table rotatably connected to the body, a lifting platform connected to the rotating table for lifting and lowering, the solar panel and the lifting platform being hinged, an angle adjustment mechanism provided between the lifting platform and the solar panel, a fixing mechanism provided between the solar panel and the placement slot, and a light tracing system provided on the body.

[0008] Furthermore, a rotating motor is provided on the machine body, and the rotating motor is connected to the rotating platform.

[0009] Furthermore, an electric telescopic cylinder is provided on the rotating platform, and a piston rod of the electric telescopic cylinder is connected to the lifting platform.

[0010] Furthermore, the angle adjustment mechanism includes an angle motor located on the lifting platform, a first connecting rod is provided on the main shaft of the angle motor, a second connecting rod is hinged to the first connecting rod, and the second connecting rod is hinged to the solar cell panel.

[0011] Furthermore, the fixing mechanism includes an electromagnetic telescopic rod, and a fixing block is provided on the frame of the solar panel, and the fixing block has only fixing holes corresponding to the electromagnetic telescopic rod.

[0012] Furthermore, the rotating platform is provided with a column, the lifting platform is provided with a connecting hole, the column is slidably connected to the connecting hole, and the column and the connecting hole are spline-matched.

[0013] Compared with the existing technology, the beneficial effect of the present invention is: when the UAV needs power supply for flight, the solar panel is first extended out of the placement slot, the sunlight angle at this time is located through the ray tracing system, and the optimal tilt angle of the solar panel is calculated, and then the solar panel is rotated and the angle is adjusted through the angle adjustment mechanism, so that the solar panel can be rotated and the angle is adjusted at any time according to the changes in the position of the sun, ensuring the optimal power generation efficiency of the solar panel.

[0023] A solar-powered drone comprises a body 1, the body 1 being provided with a propeller 2, the body 1 being provided with a placement slot 3, the placement slot 3 being provided with a solar panel 4, a tracking structure being provided between the solar panel 4 and the body 1, the tracking mechanism comprising a rotating table 5 rotatably connected to the body 1, a lifting platform 6 being lifted and lowered on the rotating table 5, the solar panel 4 being hinged to the lifting platform 6, an angle adjustment mechanism being provided between the lifting platform 6 and the solar panel 4, a fixing mechanism being provided between the solar panel 4 and the placement slot 3, and a light tracing system being provided on the body 1.

[0024] like Figure 5 As shown, in this embodiment, preferably, a rotating motor 7 is provided on the machine body 1 , and the rotating motor 7 is connected to the rotating platform 5 to drive the rotating platform 5 to rotate.

[0025] like Figure 5 As shown, in this embodiment, preferably, an electric telescopic cylinder 8 is provided on the rotating platform 5, and the piston rod of the electric telescopic cylinder 8 is connected to the lifting platform 6 to drive the lifting platform 6 to rise and fall.

[0026] like Figure 5 As shown, in this example, preferably, the angle adjustment mechanism includes an angle motor 9 located on the lifting platform 6, a first connecting rod 10 is provided on the main shaft of the angle motor 9, a second connecting rod 11 is hinged on the first connecting rod 10, and the second connecting rod 11 is hinged to the solar panel 4 to form a crank-connecting rod mechanism to drive the angle adjustment of the solar panel 4.

[0027] like Figure 4 As shown, in this example, preferably, the fixing mechanism includes an electromagnetic telescopic rod 12, and a fixing block 13 is provided on the frame of the solar panel 4. The fixing block 13 has only fixing holes 14 corresponding to the electromagnetic telescopic rod 12. When the end of the electromagnetic telescopic rod 12 is inserted into the fixing hole 14 on the fixing block 13, the solar panel 4 can be fixed. When the electromagnetic telescopic rod 12 is energized, its end can be extended out of the fixing hole 14, thereby realizing the lifting, rotation and angle adjustment of the solar panel 4.

[0028] like Figure 4 In the embodiment, preferably, the end of the electromagnetic telescopic rod 12 and the bottom of the fixed block 13 are provided with a wedge-shaped surface, which is advantageous in that the electromagnetic telescopic rod 12 can be extended and retracted by an external force when no power is applied. When the two wedge-shaped surfaces are in contact, after contact, the electromagnetic telescopic rod 12 can be retracted by pressing down the solar cell panel 4 until the fixing hole 14 is opposite to the end of the electromagnetic telescopic rod 12, and the end of the electromagnetic telescopic rod 12 is re-extended into the fixing hole 14.

[0029] like Figure 2As shown, in this embodiment, preferably, fixing mechanisms are provided on both sides of the solar cell panel 4.

The column 15 is slidably connected to the connecting hole 16, and a spline fit is heard between the column 15 and the connecting hole 16, that is, the cross-sections of the column 15 and the connecting hole 16 are spline-shaped, which can realize the sliding connection between the column 15 and the connecting hole 16, and when the column 15 rotates, the lifting platform 6 can be driven to rotate together through the spline fit.

[0031] like Figures 1 to 5 As shown, when the UAV needs power supply for flight, the electromagnetic telescopic rod 12 extends from the fixing hole 14 of the fixing block 13, and the electric telescopic cylinder 8 on the rotating platform 5 is started to lift the lifting platform 6, so that the solar panel 4 extends out of the placement slot 3. The sunlight angle at this time is located by the ray tracing system, and the optimal tilt angle of the solar panel 4 is calculated. Then, the rotating motor 7 drives the rotating platform 5 to rotate, thereby realizing the rotation of the solar panel 4. At the same time, the angle motor 9 drives the first connecting rod 10 to rotate, and the rotation of the first connecting rod 10 drives the second connecting rod 11. Finally, the solar panel 4 is rotated on the lifting platform 6 through the second connecting rod 11, so that the solar panel can be rotated and the angle can be adjusted at any time according to the changes in the position of the sun, thereby ensuring the optimal power generation efficiency of the solar panel 4.
