Abstract
The utility model relates to a device for monitoring vibration of cabin of wind power generator set, which comprises a single chip, a signal output module and acceleration sensors mounted horizontally and vertically on a wind power generator rack respectively; the single chip is connected with the signal output module through a cable; each acceleration sensor is connected with the single chip through the cable; the cable for connecting the acceleration sensor with the single chip is in turn provided with a high-pass filter, an amplifier, a low-pass filter, an AC/DC converter and an ADC module; the single chip is also connected with the low-pass filter through a DP bus; and the signal output module is provided with an interface connected with a wind power generator control system. The acceleration sensor transmits a vibration signal of the cabin of the wind power generator to a monitoring device, and when the vibration in the cabin is detected to be beyond the defined safety requirement, the signal output module sends a corresponding electric signal to the wind power generator control system so as to control the wind power generator to be stopped, so that the problem that the structure of the wind power generator is damaged due to large vibration is solved.
Description
Technical field
The utility model relates to a kind of cabin vibration monitoring device of the device that is used to monitor fan vibration, particularly a kind of wind power generating set.
Background technique
In the existing technology MW class wind turbine group carried out the device of vibration monitoring; Just monitor a vibration on the direction; Do not have storage and communication function, and do not possess the oscillating signal of gathering is carried out active analysis, processing and forms the ability of corresponding current signal.Like this in the actual motion of blower fan; Conduct to the self-excitation resonance that coupling that end thrust on the draught fan impeller, inertial force etc. have alternation shape and randomness power will cause some vibration shape resonance owing to act on blade; These vibrations are dispersed; Stay very big potential safety hazard for the safety of whole engine room inside large number quipments, can cause the serious consequence of wind energy conversion system structure when serious.
Summary of the invention
The utility model technical problem to be solved is the deficiency to existing technology, and the cabin vibration monitoring device of wind power generating set a kind of reasonable in design, simple in structure is provided.
The utility model technical problem to be solved is to realize through following technological scheme.The utility model is a kind of cabin vibration monitoring device of wind power generating set; Be characterized in: it comprises single-chip microcomputer, signal output module and level and be vertically mounted on the acceleration transducer on the blower fan frame respectively; Single-chip microcomputer is connected with signal output module through elastic cable paper; Each acceleration transducer all is connected with single-chip microcomputer through elastic cable paper; Be provided with high-pass filter, amplifier, low-pass filter, AC/DC transducer and ADC module successively on the elastic cable paper of connection acceleration transducer and single-chip microcomputer, single-chip microcomputer also is connected with low-pass filter through the DP bus, and signal output module is provided with the interface that is connected with blower fan control system.
The utility model technical problem to be solved can also further realize through following technological scheme; The cabin vibration monitoring device of above-described wind power generating set is characterized in: the interface that signal output module is connected with blower fan control system is the CAN EBI.
The utility model is transferred to monitoring device through acceleration transducer with the oscillating signal in blower fan cabin; When monitoring device detects the cabin internal vibration greater than the safety requirement set; Send corresponding electrical signal through the signal output module on this supervisory device to blower fan control system; The dead halt of control blower fan solves blower fan because of vibrating the excessive problems of bringing such as blower fan structure damage to reach.Compared with prior art; The utility model is reasonable in design, simple in structure, and the vibration situation of MW class wind turbine group is accurately monitored, and finds strong vibration and active analysis, calculating output corresponding electric signal early; Make the blower fan dead halt, prevent that effectively blower fan from damaging.
