The invention discloses a four-rotor-based fan blade detection device. The four-rotor-based fan blade detection device comprises a parallel crawling mechanism, a four-rotor flight system, a vacuum adsorption system, a detection device and a control system. The parallel crawling mechanism comprises a movable platform, push rods and a static platform, and the push rods are connected with the movableplatform and the static platform through universal joints. The four-rotor flight system comprises rotor motors, rotor motors supporting pillars, electronic speed adjusters, a flight control system and a power supply system. The vacuum adsorption system comprises suction cups, an air path, an electromagnetic valve and a vacuum pump and is used for providing adsorption force. The detection device comprises micro-cameras, ultrasonic flaw detection probes and a support for fixing the ultrasonic flaw detection probes and connected with a lower platform battery panel. The control system is an embedded system and is used for controlling the whole system to operate cooperatively. The four-rotor-based fan blade detection device can replace labor to perform dangerous overhead operation; and by utilizing a four-rotor aircraft and the parallel mechanism as carriers, the four-rotor-based fan blade detection device can land on and adhere to the low-curvature surfaces of fan blades and perform scanning detection and movement.
Description
technical field [0001] The invention relates to a fan blade detection device, in particular to a fan blade detection device based on four rotors. Background technique [0002] The continuous consumption of traditional energy sources and the aggravation of environmental problems make the application and development of new energy sources such as wind power generation extremely urgent. Wind turbines are the core equipment for wind energy applications. However, during the use of the wind power generating set, failure of the blades will cause a series of chained parts to be damaged, which will cause downtime or more serious losses. Research on fault-predictive detection and maintenance of wind turbine blades is ongoing. The countermeasures at this stage often use regular shutdown and disassembly inspections and online monitoring networks based on acoustic emission technology. In fact, there are certain limitations in the use value and application prospect of these two methods....
