High-strength anti-pulling angle moving device, tethered unmanned aerial vehicle and tethered unmanned aerial vehicle system

Abstract

The invention provides a high-strength anti-pulling angle moving device, a tethered unmanned aerial vehicle and a tethered unmanned aerial vehicle system. The angle moving device comprises a bearing,a mounting seat, a rocking bar and a tethered rope, wherein the bearing is fixed in the mounting seat, the rocking bar penetrates through the bearing so as to be connected with the bearing, a threading hole is formed in the rocking bar in a penetrating mode, the threading hole penetrates through the bearing, the tethered rope penetrates through the threading hole, a limiting block is arranged at the upper end of the tethered rope, and the limiting block is in limiting fit with the upper end of the rocking bar. Because the tethered rope is arranged in the rocking bar in a penetrating mode, thetethered unmanned aerial vehicle can perceive the positional relationship by detecting the angle of the rocking bar so that even slight twisting of the tethered rope does not affect the angle of the rocking bar; and through the design of the bearing, in the self-rotation process of the tethered unmanned aerial vehicle, the rocking bar cannot easily rotate with the tethered unmanned aerial vehicle,the tethered unmanned aerial vehicle rotates relative to the rocking bar without affecting the connection position of the rocking bar, and the angle of the rocking bar cannot be changed, so that thephenomenon that the tethered rope deviates from the connection position is not easy to occur, and the follow-up of the tethered unmanned aerial vehicle can be facilitated.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a high-strength and anti-pull angle moving device, a tethered unmanned aerial vehicle and a system. Background technique [0002] Tethered drones are mainly used for long-term uninterrupted aerial monitoring and emergency communications. They can be equipped with special visible light cameras and infrared thermal imagers, and can also be equipped with special emergency communication relay equipment. Now tethered drones have been used in military, It is widely used in many professional fields such as fire protection, petroleum, surveying and mapping, transportation and scientific research. [0003] At present, tethered UAVs use wires to connect power supply, which can provide long-term battery life, but the current mooring ropes of tethered UAVs are mostly connected to the fuselage by wires, and the wires are often soldered to the fuselage. The fuselage is connected, and w...

Problems solved by technology

[0003] At present, tethered UAVs use wires to connect power supply, which can provide long-term battery life, but the current mooring ropes of tethered UAVs are mostly connected to the fuselage by wires, and the wires are often soldered to the fuselage. The fuselage is connected. When the external force is too large, it is easy to cause the wire to be disconnected. In severe cases, accidents such as power failure and crash of the aircraft may occur.
