Description

Technical Field

[0001] The present invention relates to an unmanned aerial vehicle (UAV), in particular to a surveying and mapping UAV which is convenient for positioning and prevents sinking after falling into water, and belongs to the technical field of UAVs. Background Art

[0002] Unmanned aerial vehicle (UAV), also known as “drone”, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device.

[0003] The aircraft has no cockpit, but is equipped with autopilot, program control devices, etc. Personnel on the ground, on ships, or at the remote control station of the mother aircraft use radar and other equipment to track, locate, remotely control, telemeter, and transmit digital data.

[0004] It can take off like a normal airplane under radio remote control or be launched into the air with a booster rocket, or it can be carried into the air by a mother aircraft and dropped for flight.

[0005] During recovery, it can land automatically in the same way as a normal aircraft, or it can be recovered by remote control using a parachute or a net.

[0006] It can be used repeatedly and is widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc.

[0007] When conducting ocean mapping with existing technology, if a drone runs out of power or is damaged, it will fall directly into the water and cannot be used again. Due to the vast ocean, this is an accidental event that happens frequently for drones. After falling, data will also be lost and the drone cannot be used again. Therefore, a mapping drone that is easy to locate and prevents sinking after falling into the water is designed to solve the above problems. Summary of the Invention

[0008] The main purpose of the present invention is to provide a surveying and mapping UAV that is easy to locate and prevent from sinking after falling into water. By starting the double-headed motor to drive the connecting rod to rotate, the connecting rod drives the fan blades to rotate at high speed to adjust the rise and movement of the industrial UAV body. By using a camera to shoot and survey, the vertical azimuth is adjusted by the end adjustment motor, and the horizontal azimuth is adjusted by starting the second inner drive motor to adjust the rotation of the lower turntable. When local fan blades are damaged, the remaining first inner drive motor is started to drive the adjustment gear to cooperate with the external tooth ring to adjust the end connection block for azimuth movement, thereby adjusting the side wings for azimuth displacement. The drone continues to fly in a balanced manner. When more than three fan blades are damaged, it will fall. The speed detection module in the drone body will automatically start the air pump to open the airbag after detecting that the drone body is falling with the acceleration of gravity. The bottom bar will float up through the airbag, and then the drone body will start floating. The remaining azimuth adjustment motors will be started to adjust the angle of the side wings and insert them into the water. Then different fan blades will be started for azimuth adjustment to run in the water. Synchronously, the retractable and discharge motors will be started to adjust the retractable and retractable drum, and the rope will be pulled to drive the inner sliding rod to be recovered into the limit cylinder, and then the camera will be recovered into the limit cylinder to avoid damage to the limit cylinder.
