Engineering surveying and mapping device based on unmanned aerial vehicle

Abstract

The invention provides an engineering surveying and mapping device based on an unmanned aerial vehicle, relates to the field of surveying and mapping device technologies and engineering, and aims to solve the problems that an existing surveying and mapping device based on an unmanned aerial vehicle cannot control movement of a surveying and mapping instrument, cannot prevent the surveying and mapping instrument from making contact with the ground and cannot protect the surveying and mapping instrument during engineering surveying and mapping. The engineering surveying and mapping device comprises a main body. The main body is an unmanned aerial vehicle body, and four supporting legs are arranged at the bottom of the main body; and the top ends of buffer pieces are fixedly connected with the bottoms of the supporting legs of the main body. The surveying instrument needs a sufficient visual field during surveying, so that the bottom of the surveying instrument needs to be located below a contact plate, when the device needs to descend, the main body can be controlled to quickly descend firstly, a stress plate can drive a bearing piece to move upwards, then a spring is compressed, meanwhile, a clamping block receives power of the spring to move outwards, the outer end of the clamping block can be inserted into a rectangular groove of a guide piece, so that the bearing piece can drive the surveying instrument to be limited and fixed, and the surveying instrument cannot be damaged due to contact with the ground.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping devices, and more specifically relates to engineering surveying and mapping devices based on unmanned aerial vehicles. Background technique [0002] Before developing a piece of land or carrying out large-scale engineering construction, it is usually necessary to use mapping drones to measure and draw topographic maps and provide other information before making decisions, planning and design, so surveying and mapping is very important. [0003] For example, the application number: CN201911158254.5 relates to a UAV-based engineering surveying and mapping device, including a UAV and a protection mechanism. An inclined surveying and mapping camera is installed, and a support plate is installed on the top surface of the inclined surveying and mapping camera, and shock absorbing frame mechanisms are installed on both sides of the top surface of the supporting plate, and the shock absorbin...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an engineering surveying and mapping device based on unmanned aerial vehicles to solve the problem that the existing surveying and mapping devices based on unmanned aerial vehicles have poor stability and cannot be used during flight. The surveying and mapping instrument is more stable, and it cannot buffer the impact force when it lands, and when the existing drone-based surveying and mapping device is in use, it cannot control the movement of the surveying and mapping instrument when it lands, and it is impossible to avoid the contact between the surveying and mapping instrument and the ground. Unable to protect surveying and mapping instruments
