Description
Technical field
The invention belongs to wind turbine damage detection technology fields more particularly to a kind of fan blade to damage sync detection device.
Background technology
Wind is a kind of energy of not public hazards, very environmentally friendly using wind-power electricity generation, and the electric energy that can be generated is very huge,
Therefore more and more countries more pay attention to wind-power electricity generation.Fan blade is converted to the front end equipment of electric energy as wind energy,
The quality of performance directly determines the height of transfer efficiency.Thus its situation of periodic detection is extremely important.
Fan blade is shell structure made of a composite material, and 90% or more of weight is made of composite material,
Every generator generally has branched blade.Blade transport and installation process in, due to blade size itself and conduct oneself with dignity it is larger and
And the generation of fan blade internal injury can be caused with certain elasticity.Even more noteworthy, due to the evil of working environment
The property complicated and changeable of pessimum and operating mode, fan blade is in sunlight, acid rain, blast, self-vibration, dust storm, under conditions of salt fog etc. is unfavorable
With the variation of time, degeneration also occurs for performance, until natural cracking is generated, trachoma, surface abrasion, broken by lightning, cross
To failures such as crackles.Moreover, also will appear different degrees of fatigue damage in the process of running;If daily can carry out blade
Periodic maintenance, so that it may to avoid the maintenance cost of great number in the future, reduce the economic loss caused by shutting down.
Detecting in such a way that monitoring is combined, it can prevent and can avoid the generation of accident.At present to wind turbine
Crop leaf measuring can be divided into production quality inspection and military service blade detects in place.It is often to be lacked to the production in production process to produce quality inspection
It falls into, material tests, this detection is realization easy to operate.However the blade of military service is detected in place most of still by people
Work detects, and artificial detection is high with danger, detection efficiency is low, labor intensity is big, data are not easy to maintain and detection time mistake
The defects of long.Therefore, military service blade on-line checking gradually obtains more and more attention.It, can with the promotion of non-destructive testing technology
Non-destructive testing to be combined with advanced mechanical device, designs different military service blades using different non-destructive testing technologies and exist
Position detection.Common fan blade non-destructive testing technology has:The detection techniques such as ultrasonic wave, sound emission, X-ray, infrared thermal imaging.
But each detection method all has the advantages that respective and uses limitation, and carrys out regulation detection method there is no perfect standard
The applicable stage.Such as authorize publication No. CN204961177U, the patent document in date of publication on January 13rd, 2016 discloses a kind of wind
Machine blade detection apparatus is a kind of fan blade real-time detection apparatus using active infra-red thermal imaging, detection dress
The feature of setting will be detected manually with each parameter setting of light illuminating unit into optimum state before being to detect;Such as application publication number
CN107063602A, the date of publication patent document on the 18th of August in 2017 disclose a kind of fan blade mechanical damage detection device,
It is a kind of high based on the degree of intelligence that Digital Image Processing can accurately identify damaged blade position is carried out to image
Detection device, which solves existing pneumatic equipment bladess, there is inconvenient, detection is inaccurate, degree of intelligence is low, real
The shortcomings of poor, complicated with property;Such as application publication number CN106501280A, the patent text in date of publication on March 15th, 2017
It offers and discloses a kind of fan blade on-line measuring device and its detection method based on laser ranging, which uses three-dimensional laser
Ranging carries out blade contactless detection technique, the case where capable of effectively monitoring blade, finds failure in time.On however,
Fan blade static detection in place can only be realized by stating fan blade military service detection in place, and static detection overlong time brings phase
When the big economic loss the problems such as.Therefore, study it is a kind of be suitable for fan blade military service have in place with the device of on-line checking
Important engineering application value and practical significance.Authorization Notice No. CN20483211U, the patent in date of publication on December 2nd, 2015
Document discloses a kind of running blade of wind-driven generator detection device of wind field, which is the original using sound phase instrument
Reason, the sound that blade is sent out when receiving the rotation of wind turbine power generation machine by sound source receiving device, detects by timely data processing
Blade damaged condition, which solves the maintenance for not having the damaged condition for detecting blade of wind-driven generator promptly and accurately
The technical issues of device, and the ground that can be placed on from one determining deviation of wind turbine is detected running wind turbine.But the device
It is largely influenced by surrounding medium environment, influences image quality, and also do not accounted for when wind direction changes
When, wind turbine can also be circumferentially rotated with wind direction, to which the precondition that detection device is placed in windward side will change
Become so that the error for detecting generation is larger.
Therefore, fan blade damage check should meet military service on-line checking, and adapt to the variation of wind direction, to
The detection that can be very good to complete blade shows very intuitive defect.
