[0002] Drones are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are completely or intermittently autonomously operated by onboard computers. Drones are often more suitable for tasks that are too dirty or dangerous; drones can be divided into military and civilian applications according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian field, drones + industry applications are the real rigid demand for drones; their applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the use of drones themselves.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Example 1: Please refer to Figure 1-Figure 4 , the specific embodiments of the present invention are as follows: Its structure includes a drone 1, a remote sensing plotter 2, and a wind-resistant device 3. The drone 1 is provided with a remote sensing plotter 2 at the bottom, and the wind-resistant device 3 is installed on the top end surface of the drone 1; the drone 1 includes a wind-resistant frame 31, a fixed plug block 32, a guide groove 33, and a guide structure 34. Two fixed plug blocks 32 are provided at the bottom of the wind-resistant frame 31, and the fixed plug blocks 32 are inserted and connected to the top end surface of the drone 1. The guide groove 33 runs through the inner end surface of the wind-resistant frame 31. Two guide structures 34 are provided, and the guide structures 34 are arranged on the top of the wind-resistant frame 31. The bottom of the guide groove 33 is provided with a mounting groove 331, a cover 332, a sealing plate 333, a threaded rod 334, a servo motor 335, and a mobile power supply 336. The mounting groove 331 is located at the bottom front end of the guide groove 33. The cover 332 is mounted on the bottom end surface of the mounting groove 331. The sealing plate 333 is slidably connected to the top of the mounting groove 331. The threaded rod 334 is mounted inside the mounting groove 331, and the threaded rod 334 is movably matched with the sealing plate 333. The servo motor 335 is rotatably connected to the threaded rod 334. The sealing plate 333 includes a plate body 3331, a movable block 3332, and a sealing sleeve 3333. The bottom of the plate body 3331 is provided with a movable block 3332, the movable block 3332 is threadedly matched with the threaded rod 334, and the sealing sleeve 3333 is nested in the end surface of the plate body 3331; The tops of both sides of the wind-resistant frame 31 are sheet-shaped; The servo motor 335 drives the threaded rod 334 to rotate, so that the threaded rod 334 can be stuck in the end surface of the movable block 3332 to drive the plate 3331 to move downward, so that the guide groove 33 is in an open state, allowing the airflow to flow backward through the guide groove 33, thereby improving the wind resistance performance of the drone 1 during flight and improving the stability of the remote sensing mapping instrument 2 in surveying and mapping terrain.

[0022] Based on the above embodiment, the specific working principle is as follows: the remote sensing mapping work can be performed by using the drone 1 to drive the remote sensing mapping instrument 2 to fly in the air. When the drone 1 encounters strong winds during flight, the blades on both sides of the top of the wind-resistant frame 31 can be used to guide the airflow, thereby improving the stability of the drone 1 during flight. The servo motor 335 then drives the threaded rod 334 to rotate, so that the threaded rod 334 can be stuck in the end surface of the movable block 3332 to drive the plate body 3331 to move downward, so that the guide groove 33 is in an open state, allowing the airflow to flow backward through the guide groove 33, thereby improving the anti-wind resistance performance of the drone 1 during flight, and improving the stability of the remote sensing mapping instrument 2 in surveying and mapping terrain. At the same time, the plate body 3331 can also move upward to seal the guide groove 33, reduce the contact between the airflow and the fuselage of the drone 1, and thereby increase the flight speed of the drone.

[0023] Example 2: Please refer to Figure 5-Figure 6 , the specific embodiments of the present invention are as follows: The guide structure 34 includes a guide frame 341, an air guide groove 342, a flow groove 343, and a guide block 344. There are two guide frames 341, and the guide frames 341 are respectively arranged on both sides of the top of the wind-resistant frame 31. The air guide groove 342 is located inside the guide frame 341. There are two flow grooves 343, and the flow groove 343 is arranged at the rear end of the air guide groove 342. The guide block 344 is arranged in the middle position inside the flow groove 343. The airflow is concentrated through the air guide groove 342 and then diverted to the flow groove 343, so that the airflow impacts the end face of the guide block 344 to generate turbulence.

[0024] The guide block 344 includes a guide body 3441 and a guide plate 3342 . Both sides of the guide body 3441 are fixedly installed inside the flow groove 343 , and the guide plate 3342 is arranged on the top of the guide body 3441 .

[0025] The front end of the guide body 3441 is sharp.

[0026] There are eleven guide plates 3342 , and the guide plates 3342 are arranged on the top end surface of the guide body 3441 .

[0027] The rear end of the air guide groove 342 is provided with a slope with an angle of 30 degrees.

[0028] Based on the above embodiment, the specific working principle is as follows: the airflow is concentrated by using the air guide groove 342, and then diverted to the flow groove 343, so that the airflow impacts the end surface of the guide block 344 to generate turbulence, so that the air pressure at the rear end of the drone 1 is reduced, thereby increasing the flight speed of the drone 1, allowing the drone 1 to perform remote sensing mapping while flying at high speed, and when the drone 1 encounters a concentrated airflow, the airflow can also be guided by the aerodynamic wind-resistant frame 31, so that the drone 1 will not fall.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
