Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) monitoring technology, and in particular to a UAV monitoring device for detecting crop growth. Background Technology

[0002] With the development of agricultural modernization, the concept of precision agriculture is receiving increasing attention. Traditional methods of crop detection, such as manual field inspections, are inefficient and highly subjective. The emergence of drone technology has revolutionized crop detection. Drones can quickly cover large areas of farmland and acquire high-resolution data, which is crucial for timely understanding of crop growth, pest and disease conditions, and soil fertility.

[0003] During drone monitoring operations, the drone serves as a flight platform, providing flexible shooting positions and angles for the camera. The monitoring camera is mounted on the drone and transmits image data wirelessly. Its working principle is based on optical imaging; the lens focuses light onto the image sensor, which converts the light signal into an electrical signal. After processing and encoding, the image data is transmitted back to the ground control station.

[0004] Each drone monitoring flight requires wiping the drone's fuselage, especially the monitoring camera lens, to keep it clean and facilitate accurate image data acquisition. Regularly backing up important data and parameter settings from the monitoring camera is crucial to prevent accidental loss. Before each flight, all drone components must be inspected to rule out common malfunctions and minimize the risk of failure and accidents. However, current monitoring cameras are typically mounted on the underside of the drone fuselage. When performing tasks such as wiping, backing up data, and installation / removal for maintenance, the drone is usually inverted for convenience. However, inverted drones lack effective and stable support structures. When inverted, the rotor blades rest on the ground and bear the drone's weight, making them susceptible to damage.

[0030] The present invention will be further described in detail below with reference to the embodiments.

[0031] Specific embodiments of the UAV monitoring device for crop growth detection provided by this utility model:

[0032] Please see Figures 1-5 A drone monitoring device for detecting crop growth includes a drone body 1, a monitoring camera 3, several hinges 5, several legs 2, and several high-strength tension springs 4.

[0033] The monitoring camera 3 is installed on the lower middle part of the UAV body 1, and the UAV body 1 has several circumferentially distributed rotors on its side.

[0034] Several hinge seats 5 are installed on the side of the UAV body 1, and the hinge seats 5 are evenly distributed along the circumference of the side of the middle part of the UAV body 1.

[0035] Several legs 2 correspond one-to-one with hinges 5 and are vertically rotatably connected to the end of the UAV body 1 away from the corresponding hinges 5. The legs 2 and the rotors are alternately located on the side of the UAV body 1. The legs 2 can be vertically rotated to be located entirely on the upper side of the UAV body 1 and entirely on the lower side of the UAV body 1. When the legs 2 rotate, they pass through the gap between the rotors.

[0036] The outer end of the hinge 5 is rotatably connected to the support leg 2. The upper and lower parts of the outer end of the hinge 5 are provided with support surfaces 501 that limit the rotation angle of the support leg 2. In some embodiments, the support surfaces 501 can all be vertical surfaces. When the support leg 2 rotates to the upper or lower side of the UAV body 1 and is in a vertical state, it fits against the vertical support surface 501. The support surface 501 limits the rotation angle of the support leg 2. At this time, the total rotation angle of the support leg 2 is 180 degrees.

[0037] See Figure 4 In this embodiment, the support surfaces 501 at the upper and lower parts of the outer end of the hinge 5 are symmetrical inclined surfaces. At this time, the total rotation angle of the support leg 2 is less than 180 degrees. When the support leg 2 rotates to the uppermost or lowermost side and fits against the support surface 501, the support leg 2 is in an inclined state. The end of the support leg 2 away from the drone body 1 tilts away from the center of the drone body 1 and is in an outward expansion state, thus achieving stable support.

[0038] A high-strength tension spring 4 is connected between the side of the support leg 2 and the side of the drone body 1. The height of the connection between the high-strength tension spring 4 and the drone body 1 is the same as the height of the connection between the support leg 2 and the hinge 5. However, the high-strength tension spring 4 is closer to the side of the drone body 1, while the support leg 2 is rotatably connected to the outer end of the hinge 5, which is farther away from the side of the drone body 1 than the high-strength tension spring 4. Therefore, when the support leg 2 is manually rotated to a horizontal position, the high-strength tension spring 4 is at its maximum extension length. When the support leg 2 is rotated to the upper and lower sides of the drone body 1, the high-strength tension spring 4 uses its own strong rebound force to make the support leg 2 firmly fit against the support surface 501.

[0039] In this embodiment, two high-strength tension springs 4 are symmetrically connected to both sides of the outrigger 2. The two high-strength tension springs 4 firmly adhere the outrigger 2 to the support surface 501, maintaining the stability of the outrigger 2 and enabling it to bear the weight of the entire drone body 1. In this embodiment, the number of high-strength tension springs 4 is twice the number of outrigger 2. The high-strength tension springs 4 also provide cushioning when the drone lands.

[0040] The outrigger 2 can rotate to the upper and lower sides of the drone body 1, meaning it can provide support whether the drone body 1 is upright or inverted. To ensure the stability of the support at the end of the outrigger 2, an annular support foot 13 is connected to the outer end of the outrigger 2. The support foot 13 is a horizontal annular cylindrical structure, and the outer ring side of the support foot 13 is connected to the outer end of the outrigger 2.

[0041] To facilitate the installation, removal, and replacement of the high-strength tension spring 4, both the sides of the UAV body 1 and the legs 2 are equipped with hanging rings 6 that connect to the high-strength tension spring 4. Both ends of the high-strength tension spring 4 have hooks that connect to the hanging rings 6.

[0042] A sliding sleeve 7 is fitted on the outer side of the support leg 2, and the sliding sleeve 7 slides along the outer side of the support leg 2; a high-strength tension spring 4 is connected to the sliding sleeve 7, and hanging rings 6 that are connected to the high-strength tension spring 4 are provided on both sides of the sliding sleeve 7.

[0043] By adjusting the position of the sliding sleeve 7, the position of the outer end of the tension spring 4 can be adjusted, thereby adjusting the tension length of the tension spring 4 and the pulling force exerted by the tension spring 4 on the support leg 2. When the sliding sleeve 7 moves towards the outer end of the support leg 2, the tension spring 4 extends, increasing the pulling force applied to the support leg 2, which makes the support leg 2 fit more stably against the support surface 501. When the sliding sleeve 7 moves towards the inner end of the support leg 2, the extension of the tension spring 4 decreases, reducing the pulling force applied to the support leg 2, making it easier to manually rotate the support leg 2.

[0044] In order to adjust the position of the sliding sleeve 7, the outer side of the support leg 2 is provided with a lug plate 8, and the lug plate 8 and the hinge seat 5 are located on both sides of the sliding sleeve 7; the lug plate 8 is connected to a bolt 9 by a thread, and the bolt 9 passes through the lug plate 8; the outer side of the sliding sleeve 7 is connected to a pull ring 10, and the end of the bolt 9 passes through the pull ring 10 and is connected to a circular limiting plate 11.

[0045] The inner diameter of the pull ring 10 is smaller than the diameter of the limiting plate 11, and the limiting plate 11 cannot pass through the pull ring 10; the outer diameter of the bolt 9 is smaller than the inner diameter of the pull ring 10 and there is an annular gap between the bolt 9 and the inner side of the pull ring 10.

[0046] In this embodiment, two ear plates 8 are symmetrically connected to both sides of the support leg 2, and two pull rings 10 are symmetrically connected to both sides of the sliding sleeve 7; the number of bolts 9 and limiting plates 11 are both two symmetrically located on both sides of the support leg 2. By rotating the bolts 9, the length of the bolts 9 passing through the ear plates 8 can be changed, thereby causing the limiting plates 11 to pull the pull rings 10 and the sliding sleeve 7, causing the sliding sleeve 7 to overcome the tension of the strong tension spring 4, thus changing the length of the strong tension spring 4 and adjusting the tension of the strong tension spring 4.

[0047] When adjusting the position of the sliding sleeve 7, use a wrench to alternately rotate the two bolts 9, and do not continuously rotate only one side of the bolt 9.

[0048] To prevent the bolt 9 from loosening or changing position during use, a nut 12 is threadedly connected to the outside of the bolt 9 on the side of the ear plate 8 facing away from the pull ring 10. After determining the position of the sliding sleeve 7, rotate the nut 12 to make the nut 12 fit against the ear plate 8, which can ensure that the positions of the bolt 9 and the sliding sleeve 7 do not change during long-term use.

[0049] During takeoff monitoring, outrigger 2 is in position. Figure 1 The drone body 1 is positioned upright; when cleaning, installing, removing, backing up, or maintaining the monitoring camera 3, the outriggers 2 are positioned... Figure 5 In this state, the drone body 1 is inverted, with the monitoring camera 3 positioned on top. This reduces the difficulty of operation, prevents the propeller from contacting the ground for support, and protects the propeller. Changing the state of the outrigger 2 only requires manually rotating it. Overcoming the tension of the strong tension spring 4, the outrigger 2 is first rotated to a horizontal position. Then, as the outrigger 2 continues to rotate, the strong tension spring 4 automatically pulls the outrigger 2 to the other side of the drone body 1, and the inner side of the outrigger 2 is brought into contact with the support surface 501.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
