Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) guidance devices, in particular to an UAV airport guidance device. Background Art

[0002] A drone is an aircraft that flies by remote control. There are many types and sizes of drones. Drones of different sizes can be controlled according to different usage scenarios. For example, drones used in fire safety can be used for fire pathfinding and reconnaissance. Drones can also be used for spraying pesticides, which can save manpower and improve efficiency.

[0003] The drone components include the drone body and the guidance and landing device. After takeoff and use, the drone needs to be stored on the parking platform and put into the storage container for protection. A guidance radar is installed on the outside of the storage container to assist the drone to land more accurately on the parking platform. Since the drone is driven by high-speed rotating blades and motors when in use, a large amount of heat will be generated inside the drone when it is stored. Therefore, a cooling fan is installed inside the guidance and storage device to dissipate heat for the drone. In order to prevent dust in the air from entering the interior of the guidance device, a filter plate is installed on the outside of the cooling fan. The dust in the air can be filtered through the filter plate. However, due to the adhesion of dust, the dust will clog the filter holes on the filter plate during use, affecting the normal heat dissipation function of the drone. For this reason, we provide a drone airport guidance device to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 - Figure 6As shown, the utility model provides a technical solution: a UAV airport guidance device, including a guidance box 1, a guidance radar 2 is installed on the outside of the guidance box 1, and the guidance radar 2 is installed at the four corners of the guidance box 1. When the UAV is hovering and landing, the guidance radar 2 can guide the UAV, assist the UAV in landing, and improve the accuracy of the UAV's landing.

[0027] The inner wall of the guide box 1 is slidably connected to a support plate 3, and the lower surface of the support plate 3 is fixedly connected to a fixing frame 4. The fixing frame 4 can drive the support plate 3 to move up and down. When the drone stops on the support plate 3, it can be retracted into the inside of the guide box 1. The inner wall of the guide box 1 is fixedly connected to a limiting plate 20, and the outer surface of the limiting plate 20 is slidably connected to the outer surface of the inner part of the support plate 3. The support plate 3 can be limited by the limiting plate 20, which can improve the stability of the support plate 3 when moving and avoid shaking of the support plate 3 when moving.

[0028] The internal thread of the fixing frame 4 is connected to a threaded rod 12, and an electric motor 18 is installed inside the guide box 1. The output end of the motor 18 is fixedly connected to the outer surface of the threaded rod 12. The threaded rod 12 can be driven to rotate by the motor 18. At this time, the threaded rod 12 can drive the support plate 3 to move. The outer surface of the threaded rod 12 is fixedly connected to a baffle 19. The outer surface of the baffle 19 is slidably connected to the outer surface of the fixing frame 4. The position of the fixing frame 4 can be limited by the baffle 19 to prevent the threaded rod 12 from being out of contact with the fixing frame 4.

[0029] A covering assembly 15 is installed on the outside of the guide box 1, and the covering assembly 15 can protect the top of the guide box 1. A driving assembly 16 is installed on the outside of the support plate 3, and a positioning plate 17 is installed on the outside of the driving assembly 16. The driving assembly 16 can drive multiple groups of positioning plates 17 to move, and can drive the positioning plates 17 to move the base of the drone, and can control the drone to move to the center position of the support plate 3 and fix the drone to prevent the drone from moving due to lack of fixation.

[0030] The interior of the guide box 1 is connected to a pipe 5 , and a filter plate 6 is installed inside the pipe 5 . The air entering the pipe 5 can be filtered by the filter plate 6 to prevent dust in the air from entering the interior of the guide box 1 .

[0031] The inner wall of the guide box 1 is fixedly connected with a connecting rod 7, and the outer surface of the connecting rod 7 is slidably connected with a movable plate 8. The outer surface of the movable plate 8 is slidably connected to the inner wall of the guide box 1, and a control mechanism 9 is installed on the outside of the movable plate 8. The connecting rod 7 is located between the movable plate 8 and the inner wall of the guide box 1 and is covered with a spring 10 on the outside. One end of the spring 10 is fixedly connected to the outer surface of the movable plate 8, and the other end of the spring 10 is fixedly connected to the inner wall of the guide box 1. A brush plate 11 is installed on the outside of the movable plate 8. The control mechanism 9 can drive the brush plate 11 to move. The surface of the filter plate 6 can be cleaned by the brush plate 11 to prevent dust from being adsorbed on the filter plate 6 and clogging the mesh of the filter plate 6.

[0032] The outer surface of the fixed frame 4 is fixedly connected with a pressure plate 13, and the pressure plate 13 can drive the control mechanism 9 to work. The control mechanism 9 includes a fixed box 901, and the outer surface of the fixed box 901 is fixedly connected to the outer surface of the movable plate 8. The inner wall of the fixed box 901 is slidably connected with a wedge plate 902. The outer surface of the wedge plate 902 is slidably connected to the outer surface of the pressure plate 13. When the pressure plate 13 moves, the wedge plate 902 can be pressed to enter the interior of the fixed box 901. When the wedge plate 902 does not enter the interior of the fixed box 901, the wedge plate 902 can drive the connecting plate to move downward, which can further drive the brush plate 11 to move.

[0033] The inner wall of the fixed box 901 is fixedly connected with a spring 2 903, and one end of the spring 2 903 is fixedly connected to the outer surface of the wedge plate 902. The elastic force of the spring 2 903 is greater than the elastic force of the spring 10. In this way, when the pressure plate 13 presses the wedge plate 902, the wedge plate 902 will not move toward the inside of the fixed box 901. When the brush plate 11 moves to the bottom or the compression force of the spring 10 reaches the maximum, the wedge plate 902 will enter the inside of the fixed box 901. At this time, the brush plate 11 will be reset under the action of the spring 10 and clean the surface of the filter plate 6 again.

[0034] A fan 14 is installed inside the pipe 5, and a protective cover 21 is installed outside the guide box 1. The fan 14 can dissipate heat inside the guide box 1, and the protective cover 21 can protect the outside of the pipe 5.

[0035] Working principle: When working, the drone can be accurately guided by the guidance radar 2. At this time, the drone can land above the support plate 3. When the support plate 3 is controlled to move downward, the pressure plate 13 will follow and move. At this time, the pressure plate 13 will press the wedge plate 902. The elastic force of spring 2 903 is greater than the elastic force of spring 10. When the pressure plate 13 presses the wedge plate 902, the wedge plate 902 will not move toward the inside of the fixed box 901. At this time, the brush plate 11 will move downward to clean the filter plate 6. When the brush plate 11 moves to the bottom or the spring 10 is compressed to the maximum elastic force, the wedge plate 902 will move toward the inside of the fixed box 901. At this time, under the action of spring 10, the wedge plate 902 will move toward the inside of the fixed box 901, and the brush plate 11 will reset under the action of spring 10.
