Abstract
The utility model discloses a kind of tower barrel of wind generating set bolt fracture monitoring assemblies, it include noise transducer and vibrating sensor, noise transducer and vibrating sensor are separately connected master control system, by the sound value monitored and vibration values real-time data imputing system master control system, and accesses Central Control Room SCADA system and judged and alarmed；Noise transducer and vibrating sensor are separately mounted near the bolt of tower bottom, vibrating sensor is horizontal or vertical to be located on tested oscillation point, accelerometer, accurate measurement conversion circuit are integrated, voice signal is converted to the output of standard electric signal by noise transducer built-in sound receiving unit and conversion circuit.The utility model can send the sound value monitored and vibration values real time data to master control system, can be analyzed to obtain whether bolt is broken according to the sound value and vibration values real time data monitored.
Description
Technical field
The utility model relates to the technical fields of tower barrel of wind generating set bolt fracture monitoring, refer in particular to a kind of wind-force
Generating set tower bolt fracture monitoring assembly.
Background technique
Tower connection bolt is the important component of wind power generating set, the tower that takes place frequently in recent years bolt fracture accident.
If bolt fracture and handling failure cannot be found in time, consequence is hardly imaginable, easily causes collapse accident.The prior art can only lead to
Artificial inspection is crossed to monitor bolt fracture situation, it is time-consuming and laborious, and be not easy to find in time.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, propose a kind of safe and reliable wind-driven generator
Group tower bolt fracture monitoring assembly, can send the sound value monitored and vibration values real time data to wind power generating set
Master control system, according to the experience of artificial inspection tower bolt early period, when tower bolt fracture, sound and vibration are all abnormal big, because
This later period can be analyzed to obtain whether bolt is broken according to the sound value and vibration values real time data monitored.
To achieve the above object, a kind of technical solution provided by the utility model are as follows: tower barrel of wind generating set bolt
It is broken monitoring assembly, includes noise transducer and vibrating sensor, the noise transducer and vibrating sensor are separately connected
The master control system of wind power generating set by the sound value monitored and vibration values real-time data imputing system master control system, and accesses
The Central Control Room SCADA system of wind power generating set is judged and is alarmed；Wherein, the noise transducer and vibrating sensor point
It is not mounted near the bolt of tower bottom, and the vibrating sensor is horizontal or vertical is located on tested oscillation point, will accelerate
Degree meter, accurate measurement conversion circuit integrate, and export as 4-20mA or 0-10V, the noise transducer built-in sound
Voice signal is converted to the output of standard electric signal, exported as 4-20mA or 0-10V by receiving unit and conversion circuit.
The utility model compared with prior art, have the following advantages that with the utility model has the advantages that
1, increasingly automated integrated, it uses manpower and material resources sparingly.
2, history run and fault data be can record, post analysis is convenient for.
3, the Central Control Room SCADA system of wind power generating set can remind O&M people according to the data Realtime Alerts monitored
The timely handling failure of member.
Detailed description of the invention
Fig. 1 is the structural principle block diagram of the utility model component.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
Shown in Figure 1, tower barrel of wind generating set bolt fracture monitoring assembly provided by the present embodiment, includes to make an uproar
Sonic transducer 1 and vibrating sensor 2, the noise transducer 1 and vibrating sensor 2 are separately connected the master control of wind power generating set
System 3 by the sound value monitored and vibration values real-time data imputing system master control system 3, and accesses in wind power generating set
Control room SCADA system 4 judged and alarmed, once the sound value and vibration values that measure are more than that sound transfinites value and vibration is transfinited
Value then judges that generation bolt fracture, Realtime Alerts prompt operation maintenance personnel that corresponding seat in the plane is gone to carry out troubleshooting；Wherein, described to make an uproar
Sonic transducer 1 and vibrating sensor 2 are separately mounted near the bolt of tower bottom, and the vibrating sensor 2 can it is vertical or
Level is located on tested oscillation point, and by accelerometer, accurate measurement conversion circuit integrates (realizes traditional sensor
The function of the Vibration-Measuring System of+transmitter mode), it exports as 4-20mA or 0-10V, sound built in the noise transducer 1
Voice signal is converted to the output of standard electric signal, exported as 4-20mA or 0-10V by sound receiving unit and conversion circuit.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore all shapes according to the utility model, change made by principle, it should all cover in the protection scope of the utility model
It is interior.
