Sag and crossing measuring device based on aerial photography of unmanned aerial vehicle

Abstract

The invention relates to a sag and crossing measuring device based on aerial photography of unmanned aerial vehicle, which comprises a shell, an air cooling mechanism and a ventilation opening are arranged at the bottom of the inner surface of the shell, a rubber plug is plugged in the ventilation opening, four L-shaped rods are arranged in the shell, and the four L-shaped rods are symmetrically and fixedly connected to the air cooling mechanism; a locking assembly is arranged between the shell and the air cooling mechanism, an unmanned aerial vehicle body is arranged above the air cooling mechanism, the four corners of the bottom face of the unmanned aerial vehicle body are each fixedly connected with a set of ejector rods, and the windward arc plates in the four sets of windward arc plates in different directions can constantly extrude the air bag back and forth all the time. Therefore, in the flight process of the unmanned aerial vehicle, a motor, a circuit board, electrical elements and the like in the unmanned aerial vehicle main body are not prone to aging and damage due to heating, and the circuit board is not prone to softening. Therefore, the service life of the motor, the circuit board, electrical elements and the like in the unmanned aerial vehicle body is not easily shortened due to heating.

Description

technical field [0001] The invention relates to the technical field of aerial photography unmanned aerial vehicles, in particular to a sag and crossover measurement device based on aerial photography of unmanned aerial vehicles. Background technique [0002] Aerial photography UAV is a remote control aircraft integrated with high-definition photography and camera devices. The system mainly includes: carrier aircraft, flight control, gyro head, video transmission, ground station and communication system, etc. The flying height of aerial photography UAV is generally above 500 meters. , suitable for film and television commercials and bird's-eye view shooting, etc. This aircraft is flexible and convenient, and can quickly complete the shooting of shots; [0003] Sag refers to the vertical distance between the lowest point of the wire and the connection between the two suspension points when the wire suspension height is the same on the two adjacent base poles on the flat ground...

AI Technical Summary

Problems solved by technology

[0004] When measuring the sag of the span between two adjacent base towers in the transmission line through the aerial photography of the UAV, especially when the UAV is flying at a high speed, the violent rotation of the motor in the UAV will generate a large number of The heat, and the electrical components in the main body of the drone will also generate heat. Failure to dissipate heat in time will affect the operation of the main body of the drone, causing aging and damage to the motor and electrical components, and even the circuit board in the main body of the drone. Aging and softening will affect the service life of the UAV. In the existing technology, especially when the UAV is flying at a high speed, the heat dissipation device inside the UAV is usually equipped with a cooling net, a cooling port or a fan facing the The way of blowing air in the drone, but in this way, it is difficult to perform better heat dissipation on the motor, electrical components and the bottom of the circuit board in the main body of the drone. The internal motors, electrical components and the bottom of the circuit board accumulate a large amount of heat for a short time, which will cause damage to the main body of the drone and even reduce the service life of the drone
