Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) surveying and mapping technology, and in particular relates to a navigation auxiliary device for an ecological restoration UAV surveying and mapping instrument. Background Technology

[0002] In ecological restoration work, unmanned aerial vehicle (UAV) mapping instruments play a crucial role. They can quickly and efficiently acquire information such as topography and vegetation cover of large ecological areas, providing data support for the formulation of ecological restoration plans. The navigation system of UAV mapping instruments is the key to their precise flight and data collection. A Chinese patent application with publication number 202222078721.7 discloses a drone navigation system, including a drone body, a disc pressure plate, and a device body. An adjustment box is installed on the top of the drone body. A round rod is rotatably connected inside the adjustment box via a bearing. An elliptical block is installed on the outer surface of the round rod. A spring cylinder is installed on the inner wall of the adjustment box. This utility model uses a positioning block for positioning and installation. The disc pressure plate presses down to limit the position of the device body. The elastic tension of the limiting spring causes the limiting block to enter the limiting groove, limiting the position of the mating block and facilitating installation. While this patent has the advantage of easy installation, it still has the disadvantage of lacking auxiliary devices. The installation method of the aforementioned patent makes it impossible for the navigation device to be raised or lowered and its position fixed. In areas with unstable signal reception, such as mountainous areas, canyons, or dense forest areas, satellite signals are easily interfered with or weakened due to factors such as terrain obstruction and signal reflection. In these cases, the fixed-installation navigation device cannot be adjusted according to the usage requirements, resulting in a decrease in the positioning accuracy of the UAV, or even the loss of navigation signals, which in turn affects the smooth progress of the surveying and mapping mission. To address these issues, we provide a navigation aid device for an ecological restoration drone mapping system. Utility Model Content

[0003] The purpose of this invention is to provide a navigation auxiliary device for an ecological restoration drone mapping instrument. By combining the drone body and navigation components, it solves the problem that existing drone mapping instrument navigation devices lack auxiliary structures and cannot adjust altitude to improve signal reception strength in areas with unstable signal reception.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0005] This utility model relates to a navigation auxiliary device for an ecological restoration drone mapping instrument, comprising a drone body, a navigation component mounted on the top of the drone body, brackets fixedly connected to both sides of the bottom of the drone body, and wings mounted on both sides of the drone body. The navigation component includes a mounting plate, the bottom of which is fixedly connected to the top of the drone body, and a mounting shell fixedly connected to the top of the mounting plate. A motor is fixedly connected to one side of the bottom of the inner cavity of the mounting shell, and a screw is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the surface of the screw, and a drive rod is movably connected to the top of the threaded sleeve.

A connecting rod is fixedly connected to the top of the mounting cover, and a top cover is fixedly connected to the top of the connecting rod.

[0006] The present invention is further configured such that limit strips are fixedly connected to both sides of the inner cavity of the mounting shell, and both sides of the lifting plate are movably connected to the surface of the limit strips. The limit strips limit both sides of the lifting plate, making the movement of the lifting plate on the surface of the limit strips more stable.

[0007] The present invention is further configured such that the inner cavity of the mounting base is provided with an annular pad, the inner wall of the annular pad is in close contact with the surface of the navigator body, and after the navigator body is inserted into the inner cavity of the mounting base, the inner wall of the annular pad is in close contact with the surface of the navigator body, so that the navigator body will not loosen in the inner cavity of the mounting base.

[0008] The present invention is further configured such that the inner cavity of the mounting cover is provided with a compression pad, the inner wall of the compression pad is in close contact with the top of the surface of the navigator body, and after the navigator body is inserted into the mounting cover, the compression pad can compress and limit the surface of the navigator body, so that the navigator body will not easily detach from the inner cavity of the mounting cover.

[0009] The present invention is further configured such that openings are provided on both sides of the mounting base, and a dustproof mesh is provided in the inner cavity of the opening. After the mounting base is moved to the top of the mounting shell, the openings on both sides of the mounting base enable the navigation body in the inner cavity to receive signals better.

[0010] The present invention is further provided that an anti-slip ring is fixedly connected to the surface of the top cover, and the surface of the anti-slip ring is provided with anti-slip particles.

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1 Please see Figure 1-5 This utility model relates to a navigation auxiliary device for an ecological restoration drone mapping instrument, comprising a drone body 1, a navigation component 2 mounted on the top of the drone body 1, brackets 3 fixedly connected to both sides of the bottom of the drone body 1, and wings 4 mounted on both sides of the drone body 1. The navigation component 2 includes a mounting plate 201, the bottom of which is fixedly connected to the top of the drone body 1, and a mounting shell 202 fixedly connected to the top of the mounting plate 201. A motor 203 is fixedly connected to one side of the bottom of the inner cavity of the mounting shell 202, and the output end of the motor 203 is fixedly connected to... A screw 204 is connected, and a threaded sleeve 205 is threadedly connected to the surface of the screw 204. A drive rod 206 is movably connected to the top of the threaded sleeve 205. A lifting plate 207 is movably connected to the end of the drive rod 206 away from the threaded sleeve 205. A mounting base 208 is fixedly connected to the top of the lifting plate 207. A mounting cover 209 is threadedly connected to the top of the mounting base 208. A navigator body 210 is provided in the inner cavity of the mounting cover 209. A connecting rod 211 is fixedly connected to the top of the mounting cover 209. A top cover 212 is fixedly connected to the top of the connecting rod 211.

[0025] Specifically: When the motor 203 is turned on, the output end of the motor 203 drives the screw 204 to rotate. The screw 204 drives the threaded sleeve 205 on its surface to move axially along the direction of the screw 204. The threaded sleeve 205 drives one end of the drive rod 206 to move. The other end of the drive rod 206 drives the lifting plate 207 to move upward. The lifting plate 207 drives the mounting base 208 on its top and the navigator body 210 in its inner cavity to move upward above the mounting shell 202. By optimizing the receiving environment, the signal strength received by the navigator body 210 is improved.

[0026] Example 2 Please see Figure 1-5Based on Embodiment 1, limit strips are fixedly connected to both sides of the inner cavity of the mounting shell 202, and the two sides of the lifting plate 207 are movably connected to the surface of the limit strips. An annular pad is provided in the inner cavity of the mounting base 208, and the inner wall of the annular pad is in close contact with the surface of the navigator body 210. A compression pad is provided in the inner cavity of the mounting cover 209, and the inner wall of the compression pad is in close contact with the top of the surface of the navigator body 210. A through-hole 5 is provided on both sides of the mounting base 208, and a dustproof net 6 is provided in the inner cavity of the through-hole 5. An anti-slip ring is fixedly connected to the surface of the top cover 212, and anti-slip particles are provided on the surface of the anti-slip ring. A buffer strip is fixedly connected to the bottom of the bracket 3, and an arc-shaped support pad 7 is fixedly connected to the bottom of the buffer strip. Light strips are provided on both sides of the top of the drone body 1, and mounting pieces are fixedly connected to both sides of the light strips.

[0027] Specifically: the limiting strip limits both sides of the lifting plate 207, making the movement of the lifting plate 207 more stable on the surface of the limiting strip. After the navigator body 210 is inserted into the inner cavity of the mounting base 208, the inner wall of the annular pad abuts against the surface of the navigator body 210, preventing the navigator body 210 from loosening within the inner cavity of the mounting base 208. After the navigator body 210 is inserted into the mounting cover 209, the compression pad compresses and limits the surface of the navigator body 210, preventing the navigator body 210 from easily detaching from the inner cavity of the mounting cover 209. The mounting base 208... After being moved above the mounting shell 202, the openings 5 ​​on both sides of the mounting base 208 enable the navigation body 210 inside the cavity to receive signals better. The anti-slip ring can increase the friction of the top cover 212 surface, making it easier for the staff to pinch the top cover 212 and rotate it. The buffer support structure composed of the buffer strip and the arc support pad 7 can buffer the impact force generated when the bracket 3 contacts the ground, thus protecting the UAV body 1 and the navigation component 2. The two light strips emit light, making it easier for the staff to observe the movement of the surveying UAV in poor lighting conditions.

[0028] The working principle of this utility model is as follows: First, insert the navigator body 210 into the inner cavity of the mounting cover 209. Then, move the top cover 212, which drives the mounting cover 209 and the navigator body 210 to be inserted into the inner cavity of the mounting shell 202. Rotate the top cover 212, which drives the mounting cover 209 to rotate. Screw the mounting cover 209 onto the top of the mounting base 208, thereby inserting the bottom of the navigator body 210 into the inner cavity of the mounting base 208. When the signal strength received by the navigator body 210 weakens during the flight of the mapping drone, the motor 203 can be turned on. The output end of the motor 203 drives the screw 204 to rotate, and the screw 204 drives the threaded sleeve on its surface. 205 moves axially along the direction of screw 204. The threaded sleeve 205 drives one end of drive rod 206 to move, and the other end of drive rod 206 drives lifting plate 207 to move upward. Lifting plate 207 drives the mounting base 208 on its top and the navigation body 210 in its inner cavity to move upward above the mounting shell 202. By optimizing the receiving environment, the strength of the signal received by the navigation body 210 is improved. After the mapping UAV lands, the bottom of the bracket 3 contacts the ground. The buffer support structure composed of the buffer strip and arc support pad 7 at the bottom of the bracket 3 can buffer the impact force generated when the bracket 3 contacts the ground, and avoid the impact force from damaging the UAV body 1 and the navigation component 2 on its top.
