Aerial monitoring type unmanned aerial vehicle

Abstract

The invention relates to the technical field of unmanned aerial vehicles, and discloses an aerial monitoring type unmanned aerial vehicle which comprises a fixed circular plate, a remote controller and an air sampling bag, wherein an external solar flexible charging panel is fixedly mounted on the upper surface of the fixed circular plate. The hydrogen compression tank and the folding bag are arranged, when the unmanned aerial vehicle rises to a preset height, the hydrogen compression tank is used for filling hydrogen into the folding bag through the hydrogen filling electromagnetic valve, thebuoyancy of the unmanned aerial vehicle is increased, the rotating speed of the fan blades can be reduced, low energy mode operation is entered, the power consumption in the battery is reduced, therefore, the navigation time of the unmanned aerial vehicle is prolonged, the monitoring range and the monitoring time of the unmanned aerial vehicle are expanded, collision between airflow and the fan blades is reduced, the stability of the unmanned aerial vehicle is improved, meanwhile, through arrangement of the first servo motor and the second servo motor, the rotating posture of the fan blades can be changed, balance can be formed between the fan blades and the airflow, and the stability between the unmanned aerial vehicles is further improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an aerial monitoring unmanned aerial vehicle. Background technique [0002] Environmental protection is a basic national policy of our country. With the development of environmental protection in our country and the continuous deepening of environmental management, the monitoring and investigation of the effective boundary of pollution sources has become the top priority. Most areas still use manual sampling and experiments. Atmospheric detection means based on indoor analysis, but this method cannot monitor the real-time emission of pollutants in a timely and efficient manner, so the use of drones to carry air monitoring equipment for real-time investigation and rapid monitoring came into being, but at present There are still some deficiencies in using drones for air detection, as follows: [0003] UAVs use multiple rotors to fly, and use different steering bet...

[0002]Environmental protection is a basic national policy of our country. With the development of environmental protection in our country and the continuous deepening of environmental management, the monitoring and investigation of the effective boundary of pollution sources has become a The most important thing is that most areas still use manual sampling and laboratory analysis-based atmospheric detection methods, but this method cannot monitor the real-time emission of pollutants in a timely and efficient manner, so drones are used to carry air Monitoring equipment for real-time investigation and rapid monitoring came into being, but there are still some shortcomings in the use of drones for air detection, as follows:

[0003] UAVs use multiple rotors to fly, and use different steering between multiple rotors for balance and different speeds for horizontal flight, but this kind of flight mode, It is greatly affected by the fluctuation of the external airflow, which makes the drone shake a lot, which has a great impact on the monitoring accuracy

[0004]Because the drone is equipped with batteries as energy for flight, its endurance is severely limited. On the one hand, its monitoring range is greatly reduced, and on the other hand, the air The time for monitoring equipment to detect polluted areas is short, so it is impossible to carry out multi-group sampling and detection, and the time interval for extracting samples is short, and the time for air to flow relatively is short, so it is impossible to make a comprehensive summary of the pollution detection in this area
