Description

Technical Field

[0001] The utility model relates to a landing platform, in particular to an unmanned aerial vehicle (UAV) aerial survey landing platform, and belongs to the technical field of unmanned aerial vehicles. Background Art

[0002] Drone aerial survey is a technology that uses drones equipped with various sensors to conduct aerial measurements and obtain remote sensing images. Through drone aerial survey, a wide range of surface information can be obtained in a short period of time, including topography, landforms, surface coverage and other data. These data have important application value in geological exploration, environmental monitoring, urban planning, agriculture and forestry and other fields.

[0003] A drone landing platform provides space for drones to land and take off safely. It is a facility specially designed for drones, mainly temporarily set up in ground or water areas.

[0004] China Public Authorized Invention: CN217575625U discloses a drone landing platform and a drone system, wherein the drone landing platform comprises: a parking platform, wherein the parking platform is provided with at least one air guide hole; and a first air guide driving member, wherein the first air guide driving member is arranged below the parking platform, and the first air guide driving member is used to guide the airflow on the windward side of the parking platform from the air guide hole to the leeward side of the parking platform. The disturbance of the drone caused by the ground effect can be overcome, and the stability of the drone during takeoff or landing can be improved.

Therefore, a UAV aerial survey landing platform is proposed. Utility Model Content

[0036] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-5 As shown, the embodiment of the utility model provides a UAV aerial survey landing platform, including a platform component 1 and a clamping mechanism 2, wherein the platform component 1 includes a platform base 101, a wind plate 102 and a UAV body 103;

[0043] In one embodiment, the clamping mechanism 2 further includes four through slots 202 and four connecting blocks 204;

[0044] Among them, four through slots 202 are respectively opened on one side of four clamping plates 201, one end of four electric push rods 203 is respectively hinged to the inner side wall of the four through slots 202, four connecting blocks 204 are symmetrically fixedly connected to the bottom of the inner side wall of the platform base 101, piston rods of the four electric push rods 203 are respectively hinged to the inner side wall of the four connecting blocks 204, and one side of the four clamping plates 201 is fixedly connected with a rubber pad 51;

[0045] The piston rod of the electric push rod 203 pushes the connecting block 204 to drive the clamping plate 201 to move. The moving clamping plate 201 drives the rubber pad 51 to clamp and fix the legs of the drone body 103. The provided rubber pad 51 is used to increase the friction between the clamping plate 201 and the legs of the drone body 103.

[0046] In one embodiment, the connection mechanism 3 includes two connection plates 301 and four clamping blocks 302;

[0047] Among them, four clamping blocks 302 are respectively fixedly connected to the two ends of the two connecting plates 301, and the inner side walls of the clamping blocks 302 are slidably connected to the outer side walls of the legs of the drone body 103;

[0048] The clamping block 302 is used to clamp the legs of the drone body 103 and the connecting plate 301 .

[0049] In one embodiment, the positioning and guiding mechanism 4 includes a housing 401, a driving motor 402, a wire roller 403, a guide wire 404, a magnetic block 405 and a magnet block 406;

[0050] Among them, the casing 401 is fixedly connected between the two connecting plates 301, the driving motor 402 is installed on one side of the inner wall of the casing 401, the wire roller 403 is rotatably connected to the middle of the inner wall of the casing 401, the output shaft of the driving motor 402 is fixedly connected to one end of the wire roller 403, an expansion interface 52 is provided at the bottom of the unmanned aerial vehicle body 103, a control wire 53 is connected between the expansion interface 52 and the casing 401, a storage seat 54 is fixedly connected to the bottom of the casing 401, the outer wall of the magnetic block 405 is slidably connected to the inner wall of the storage seat 54, a counterweight block 56 is fixedly connected to one side of the inner wall of the casing 401, one end of the guide wire 404 is wound around the outer wall of the wire roller 403, the other end of the guide wire 404 passes through the inner wall of the casing 401 and is fixedly connected to the magnetic block 405, and a magnet block 406 is fixedly connected to the middle of the inner wall of the platform base 101;

[0051] The output shaft of the driving motor 402 drives the wire roller 403 to rotate, and the rotating wire roller 403 releases the guide wire 404, so that the magnetic block 405 drives the guide wire 404 to move under the action of gravity, and then the guide wire 404 is used to pull the magnetic block 405.

[0052] When the utility model is in operation: before the UAV performs aerial survey, the connecting plate 301 is moved to drive the connecting plate 303 to connect with the legs of the UAV body 103, so that the housing 401 is installed and fixed above the UAV body 103, and then the housing 401 and 502 are connected by the control wire 53, so that the driving motor 402 is powered, thereby completing the preparation operation before the aerial survey.

[0053] When the drone aerial survey is completed and is ready to land, the platform base 101 is placed at the designated location and kept at a safe distance. The remote control end is then used to control the drone body 103 to fly above the platform base 101. The remote control end is then used to control the drone body 103 to start the drive motor 402 using the expansion interface 52 and the control wire 53. The output shaft of the drive motor 402 drives the wire roller 403 to rotate. The rotating wire roller 403 releases the guide wire 404, so that the magnetic block 405 drives the guide wire 404 to move under the action of gravity.

The magnet block 406 is then used to adsorb the magnetic block 405 so that the platform base 101 and the drone body 103 can be connected using the guide wire 404.

[0054] When the drone is ready to land, the remote control end controls the drone body 103 to start the drive motor 402 using the expansion interface 52 and the control wire 53 to drive the wire roller 403 to rotate in the opposite direction, so that when the drone body 103 lands, the guide wire 404 is reeled in, and the guide wire 404 is used to tow and guide the drone body 103, thereby reducing the influence of backflow and turbulence on the posture of the drone body 103 and improving the stability of the drone. Then, the airflow generated when the drone lands vertically is guided by the wind plate 102 in cooperation with the platform base 101 to reduce the backflow and turbulence generated during landing.

[0055] When the drone lands vertically to a specified height, the drone body 103 is controlled by the remote control end to adjust its direction, and then the piston rod of the electric push rod 203 pushes the connecting block 204 to drive the clamping plate 201 to move. The moving clamping plate 201 drives the rubber pad 51 to clamp and fix the legs of the drone body 103, thereby preventing direct contact between the drone and the landing platform, improving the landing stability, and directly fixing the drone above the platform.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
