Abstract
The utility model provides a monitoring device for falling of foreign matters in a wheel hub of a wind turbine generator system, which can solve the problems that the falling of the foreign matters in the wheel hub can not be monitored in the prior art and the occurrence of failure can not be timely prevented. The monitoring device comprises a pulling force sensor, a variable pitch controller and an electrical control loop, and the technical key points are as follows: a collector for the falling foreign matters, which is arranged in the wheel hub, is used for connecting the pulling force sensor between a rivet button hole arranged at a vertex and an inner lifting lug fixed on a connecting plate in the wheel hub through a traction cable, thereby enabling the digital quantity signal output end of the pulling force sensor to utilize a transmission line to connect with the digital quantity input end of the variable pitch controller. The structural design is reasonable, and monitored signals of falling of the foreign matters in the wheel hub can be rapidly sent to the variable pitch controller, thereby enabling the variable pitch controller to timely adopt measures to protect the safe operation of the wind turbine generator system.
Description
Technical field
The utility model relates to a kind of wind-powered electricity generation unit operation safety monitoring assembly, and the inner foreign matter of the particularly a kind of wind generator unit wheel hub monitoring device that drops belongs to technical field of wind power generation.
Background technique
Wind-powered electricity generation is as green energy resource, just promote in worldwide at present, domestic newly-built wind field and Fan Equipment MANUFACTURER all develop rapidly, and the wind power generating set single-machine capacity is also in rapid expansion, as main force's type, it mostly is the speed-changing oar-changing method of operation with the megawatt-level wind unit.Axial fan hub inside has comprised pitch-controlled system cabinet, pitch-controlled system conjunction cable, has become multiple electric, machinery such as oar motor, retarder, lighting protection device, blade fixing bolt, and equipment mostly is metal material.Axial fan hub is a rotary component, and in the fan operation process, in a single day wheel hub is inner to have object to drop, and object will bump with other equipment in wheel hub, damages the equipment in the wheel hub; If blower fan can not in time detect fault, still be in running state, will cause major accident.The foreign matter fault that drops is the huge hidden danger of blower fan safety, and existing axial fan hub design does not have safety monitoring assembly, can not monitor foreign matter and drop, and can't prevent in time that fault from taking place.
The model utility content
The purpose of this utility model provides the inner foreign matter of a kind of wind generator unit wheel hub monitoring device that drops; the inner foreign matter of wheel hub that can not monitor that has solved the prior art existence drops; can't in time prevent the problem that fault takes place; its reasonable in design; the signal that the inner foreign matter of the wheel hub that monitors can be dropped sends to rapidly and becomes the oar controller; change oar controller can in time be taken measures, thus the safe operation of protection wind-powered electricity generation unit.
The technological scheme that the utility model adopted is: the inner foreign matter of this wind generator unit wheel hub monitoring device that drops comprises pulling force sensor, become oar controller and electric control loop, its technological points is: the foreign body collector that drops that is arranged in the wheel hub is connected described pulling force sensor between the interior hanger of the riveting buttonhole at place, summit and connecting plate by traction rope, makes the digital quantity signal output terminal of described pulling force sensor utilize transmission line to be connected with the digital quantity input end of described change oar controller.
The described foreign body collector that drops selects for use polytetrafluoroethylmaterial material to make the trigone low temperature resistant, corrosion-resistant, that pull resistance is strong.
The described foreign body collector mounting plane that drops becomes 30～60 degree angles with the fan blade plane of rotation, and makes described drop foreign body collector and the normal operation of not interfering interior other equipment of wheel hub after traction rope is connected.
Advantage and the good effect that the utlity model has are: because the utility model is provided with the foreign body collector that drops in wheel hub; and by traction rope with pulling force sensor be connected the foreign body collector summit place of dropping the riveting buttonhole and interior hanger between; make the digital quantity signal output terminal of pulling force sensor utilize transmission line to be connected with the digital quantity input end that becomes the oar controller; its reasonable in design; institute thinks that wind power generating set provides the inner foreign matter of the wheel hub monitoring trouble signal that drops; and send signal to change oar controller, make to become the safe operation that the oar controller can in time take measures to protect the wind-powered electricity generation unit.The inner foreign matter of wheel hub that can not monitor that it has solved the technology existence drops, and can't in time prevent the problem that fault takes place.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a kind of structural representation of the utility model.
Sequence number explanation among the figure: hanger in 1,2 traction ropes, 3 pulling force sensors, 4 transmission lines, 5 riveting buttonholes, 6 foreign body collectors that drop, 7 become oar controllers, 8 connecting plates.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1.The inner foreign matter of this wind generator unit wheel hub monitoring device that drops comprises the connecting plate 8 that is arranged on hanger 1 in having in the wheel hub, and pulling force sensor 3 becomes oar controller 7 and electric control loop.Wherein be provided with in the wheel hub drop foreign body collector 6 by traction rope 2 with pulling force sensor 3 be connected the place, foreign body collector summit that drops riveting buttonhole 5 and interior hanger 1 between, make the digital quantity signal output terminal of pulling force sensor 3 utilize transmission line 4 to be connected with the digital quantity input end of change oar controller 7.The foreign body collector 6 that drops selects for use polytetrafluoroethylmaterial material to make the trigone low temperature resistant, corrosion-resistant, that pull resistance is strong.The mounting plane of foreign body collector 6 of dropping becomes 30～60 degree angles with the fan blade plane of rotation, and drop foreign body collector 6 and the normal operation of not interfering interior other equipment of wheel hub after traction rope 2 is connected.
When having foreign matter to drop in the wheel hub; owing to be subjected to gravity and action of centrifugal force; foreign matter is fallen on the foreign body collector that drops; cause that the foreign body collector vibration of dropping is stressed; pulling force sensor sends to change oar controller with the mechanically stressed electronic signal that converts to, becomes the oar controller and will in time take measures to protect the safe operation of wind-powered electricity generation unit.
