The invention provides a dual-rotor water-air amphibious unmanned aerial vehicle with a plume-like electric eel structure, which comprises a main body assembly, and the main body assembly comprises a triangular bracket, a fuselage main body, an electric eel driving mechanism, a rotary connecting piece, a U-shaped clamping groove, the plume-like electric eel structure and a load platform. According to the unmanned aerial vehicle, the line-like electric eel structures are arranged on the two sides of the fuselage main body, so that the unmanned aerial vehicle can enter and exit water without an underwater propeller or mode switching, and the structures are low in movement energy consumption, so that the unmanned aerial vehicle has the capability of working for a long time and can be flexibly switched between an air mode and a water mode; meanwhile, the system has excellent performances such as ultra-silence, high endurance and high efficiency; according to the invention, the attitude control is realized through a double-rotor structure consisting of the waterproof brushless motor, the output shaft and the folding propeller assembly and through the tilting mechanisms which are mounted front and back, the tilting mechanisms enable the rotors to deflect, different attitudes and motions can be realized through different tilting directions and tilting speeds, and the attitude stability and the motion control are enhanced.

The invention relates to an active lift augmentation tandem wing type ground effect aircraft, and relates to the field of ground effect aircrafts. The defects that a stable take-off environment is needed, take-off time is long, and operation is complex are overcome. An active lift-increasing tandem wing type ground effect aircraft comprises a machine body, a cockpit is formed in the middle of the top of the machine body, connecting pieces symmetrically arranged in the direction of the machine body are fixedly installed on the front side and the rear side of the machine body correspondingly, and wing structures are fixedly connected to the connecting pieces on the front side and the connecting pieces on the rear side correspondingly; the inclination angle between the wing structures fixed to the connecting pieces on the front side of the aircraft body and the ground, the inclination angle between the wing structures fixed to the connecting pieces on the rear side of the aircraft body and the ground and the inclination angle between the wing structures fixed to the connecting pieces on the rear side of the aircraft body are larger than the inclination angle of the front-side wings. By means of the tandem wing type layout, the inclination angles of the paddles, the front wing structure and the rear wing structure relative to the ground are increased, and when the aircraft runs, the aircraft can obtain the maximum lift force compensation under the influence of the ground effect.

The utility model discloses a bracket for a robotic dog to carry a drone, comprising: a base, which is installed on the back bearing surface of the robotic dog; a support block is installed on the base plate surface, a support plate is installed at the top of the support block, the support plate is used to carry the drone, side plates are vertically installed on both sides of the support plate, an electromagnetic locking module is installed on the inner plate surface of the side plates, the electromagnetic locking module is used to limit the drone, a communication interface slot is formed on the support plate surface, a communication contact block is arranged in the communication interface slot, a communication contact point adapted to the communication contact block is arranged at the bottom of the drone, and the drone is electrically connected to the robotic dog through the communication contact block. The utility model realizes ground-air cooperation by the robotic dog carrying the drone. In case of emergencies, the drone can directly detach from the back of the robotic dog and take off quickly, avoiding the time delay of manual deployment.

This utility model provides a mother-and-child rescue device, belonging to the technical field of water rescue equipment. It includes an unmanned lifeboat, an intelligent rescue raft, and a flying rescue boat. A support frame is installed in the middle of the unmanned lifeboat's hull, and a pair of cylinders are installed at the bottom of the support frame. Each cylinder has a clamping mechanism at its bottom, and each clamping mechanism includes an arc-shaped gripper connected to the cylinder. A pair of handles are installed on the top of the intelligent rescue raft. A dustproof box is installed on the tower of the unmanned lifeboat. This utility model uses cylinders to move the connector within the clamping mechanism, thereby moving the connecting groove hinged to the connector and the movable arm. This allows the arc-shaped gripper connected to the movable arm to open, close, or clamp, thus clamping and fixing the handles. This allows the intelligent rescue raft to be suspended on the unmanned rescue boat. The flying rescue boat is fixed and supported by a support rod inside the dustproof box, facilitating the rapid deployment and use of the intelligent rescue raft.
