With a level platform cart, this facilitates safe take-off and landing of agricultural drones on uneven planting areas.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) assisted take-off and landing technology, and in particular to an agricultural protection UAV take-off and landing assisted device. Background Technology

[0002] Agricultural drones are unmanned aircraft used for the protection of agricultural and forestry plants. They are mainly controlled by ground remote control or GPS flight control to spray pesticides, seeds, powders, etc.

[0003] However, in the existing technology, the take-off and landing sites of existing drones need to meet the basic conditions of "flat, firm and free from interference" to avoid situations where the drone tilts, bumps or lacks power during take-off or landing due to ground problems. However, the soil in agricultural and forestry plant planting areas is mostly uneven, making it difficult to find suitable take-off and landing sites. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies: the take-off and landing sites for drones need to meet the basic conditions of being "flat, firm, and free from interference" to avoid situations where drones tilt, bump, or lack power during take-off or landing due to ground issues. However, the soil in agricultural and forestry planting areas is mostly uneven, making it difficult to find suitable take-off and landing sites.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plant protection drone take-off and landing auxiliary device, including a platform cart, a tilt sensor fixedly connected to the center of the upper surface of the platform cart, a controller and a mobile power supply fixedly connected to one side of the platform cart surface, mounting blocks provided at the four corner edges of the platform cart, a rotating component fixedly connected to one end of the mounting block, and the rotating component is movably connected to the platform cart, a positioning block fixedly connected to one end surface of the rotating component, and the positioning block is interlocked with the platform cart, and connecting components are rotatably connected to both sides of the mounting block, and an electric telescopic rod is fixedly connected to one end of the connecting component.

[0006] In one preferred embodiment, a push rod is fixedly connected to one end of the platform cart.

[0007] In a preferred embodiment, a pad is fixedly connected to the lower end surface of the electric telescopic rod.

[0008] In a preferred embodiment, support plates are fixedly connected to the lower surfaces at both ends of the platform cart.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention involves moving a platform cart to the vicinity of the planting area, then changing the horizontally placed electric telescopic pole to a vertical position. A power source is then supplied to the tilt sensor and controller. The tilt sensor detects the levelness of the platform cart and transmits the data to the controller in real time. The controller receives and analyzes the data. If the controller determines that the platform cart is tilted, it will control the electric telescopic poles at the corners of the platform cart to extend and retract, adjusting the height of the four corners. When the platform cart detects that it is approaching level, the controller stops the extension and retraction of the electric telescopic poles. With a level platform cart setup, this facilitates safe take-off and landing of agricultural drones on uneven planting areas. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] like Figure 1-3As shown, this utility model provides a technical solution: a plant protection drone take-off and landing auxiliary device, including a platform trolley 1. A tilt sensor 3 is fixedly connected to the center of the upper surface of the platform trolley 1. The tilt sensor 3 is used to detect the overall levelness of the platform trolley 1. A controller 4 and a mobile power supply 5 are fixedly connected to one side of the surface of the platform trolley 1. The mobile power supply 5 provides power to the tilt sensor 3, the controller 4, and the electric telescopic rod 10. The controller 4 receives information sent by the tilt sensor 3 in real time and adjusts the extension and retraction of the electric telescopic rod 10 according to the information, thereby facilitating the leveling of the platform trolley 1. The platform trolley 1 is adjusted to a horizontal position. Mounting blocks 6 are installed at each of the four corner edges of the platform trolley 1. A rotating component 7 is fixedly connected to one end of each mounting block 6, and the rotating component 7 is movably connected within the platform trolley 1. A positioning block 8 is fixedly connected to one end of the rotating component 7, and the positioning block 8 is interlocked with the platform trolley 1. The rotating component 7 allows the mounting blocks 6 to rotate, enabling the electric telescopic rod 10 to be changed from a vertical to a horizontal position when not in use, reducing the overall space occupied by the device and facilitating its transport. When the electric telescopic rod 10 is changed to a vertical or horizontal position, the mounting block 6 is mounted at one corner. The mounting block 6 is pushed towards the edge of the platform cart 1, causing the positioning block 8 to be inserted into the platform cart 1, locking the rotation of the rotating part 7, thereby maintaining the stability of the electric telescopic rod 10 when it is changed to a vertical or horizontal position. Connecting parts 9 are rotatably connected to both sides of the mounting block 6, and the electric telescopic rod 10 is fixedly connected to one end of the connecting part 9. The platform cart 1 is moved to the vicinity of the plant planting area, and then the horizontally placed electric telescopic rod 10 is changed to a vertical position. Afterwards, the mobile power supply 5 is powered on the tilt sensor 3 and the controller 4. The tilt sensor 3 is used to detect the levelness of the platform cart 1 and transmit the data. The data is transmitted in real time to controller 4. Controller 4 receives and analyzes the data. After analysis, if controller 4 determines that the platform trolley 1 is tilted, it will control the electric telescopic rod 10 at the corner of the platform trolley 1 to extend and retract to adjust the height of the four corners of the platform trolley 1. At this time, the mounting block 6 at the corner of the platform trolley 1 rotates at the connector 9. When the platform trolley 1 detects that the platform trolley 1 is approaching a level position, controller 4 stops the extension and retraction adjustment of the electric telescopic rod 10. At this time, with the platform trolley 1 set up on a flat surface, it is convenient to assist the plant protection drone in taking off and landing safely on uneven planting sites.

[0019] Example 2

[0020] like Figure 1-3As shown, a push rod 2 is fixedly connected to one end of the platform cart 1. The push rod 2 allows workers to manually move the platform cart 1 by holding the push rod 2. A pad 11 is fixedly connected to the lower surface of the electric telescopic rod 10. The pad 11 increases the ground contact area of ​​the lower end of the electric telescopic rod 10, improving the stability of the electric telescopic rod 10 on the ground. Support plates 12 are fixedly connected to the lower surfaces of both ends of the platform cart 1. When the electric telescopic rod 10 is in a flat position, one end of the electric telescopic rod 10 is placed on the support plate 12. The support plate 12 supports one end of the electric telescopic rod 10, improving the stability of the electric telescopic rod 10 when it is flat.
