Hanging type multifunctional unmanned aerial vehicle system for building exterior wall operation

Abstract

The invention discloses a hanging type multifunctional unmanned aerial vehicle system for the building exterior wall operation. The hanging type multifunctional unmanned aerial vehicle system comprises an electric capstan device, a ground remote control device and a cleaning device of a hanging type multifunctional unmanned aerial vehicle for the building exterior wall operation; the cleaning device of the hanging type multifunctional unmanned aerial vehicle for the building exterior wall operation is connected with the electric capstan device and the ground remote control device correspondingly; the electric capstan device is used for transmitting high-voltage direct current and water or other working mediums into the cleaning device of the hanging type multifunctional unmanned aerial vehicle for the building exterior wall operation; the ground remote control device is used for realizing the control over the operation posture of an unmanned aerial vehicle by operators; and the cleaning device of the hanging type multifunctional unmanned aerial vehicle for the building exterior wall operation is used for indirectly adjusting the contact force between a cleaning roller and a wall surface through adjusting the posture of the unmanned aerial vehicle, and cleaning of different stains is realized. According to the hanging type multifunctional unmanned aerial vehicle system for the building exterior wall operation, the flying height of the unmanned aerial vehicle is not limited by a mooring rope, and the hanging type multifunctional unmanned aerial vehicle system for the building exterior wall operation can be used for high-risk work such as cleaning, spraying and maintenance of exterior walls of tall buildings.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a multifunctional unmanned aerial vehicle system for hanging the external walls of buildings. Background technique [0002] The tethered rotor UAV is a kind of buoyancy generated by the rotation of the UAV rotor, which overcomes its own and load gravity to achieve suspension, ascent, descent and other actions in the air. At the same time, it is tied to the ground position or On the traction tethered vehicle, relying on multi-functional cables to achieve long-term fixed-point stay in the air, and can control the floating height of its suspension in the atmosphere, the tethered UAV has a long time to stay in the air, low cost of use, and easy maintenance. However, the tethered UAV has the following problems: First, during the ascent of the UAV, as the altitude increases, the load of the UAV (the weight of the tethered rope) is getting larger and larger. Most of th...

Problems solved by technology

[0004] The main problem of the tethered UAV system is: as the height of the UAV increases, the load brought by the tethered cable of the UAV becomes more and more The larger the UAV rotor is, the more lift generated by the UAV rotor is used to overcome the gravity of the tethered cable, and the energy utilization rate of the system decreases significantly as the height of the UAV increases. As the height of the drone increases, the input power required is increasing. In order to prevent damage to the drone, it is necessary to ensure that the flying height of the drone cannot be too high, so the flying height of the drone is severely limited; in addition, because The aircraft relies on its own power to control the attitude to maintain a stable flight. If there is a problem with the flight system, it will lead to accidents such as crashes.
