Abstract
The invention provides a device for monitoring falling of foreign matters in a wheel hub of a wind turbine generator set, which can solve the problems that the falling of the foreign matters in the wheel hub can not be monitored and the occurrence of failure can not be prevented timely. The device comprises a tension sensor, a variable-pitch controller and an electrical control loop. The invention has the following technical key points that a falling foreign matter collector which is arranged in the wheel hub connects the tension sensor between a rivet button hole at the apex and an inner lifting lug of a connecting plate fixed in the wheel hub by virtue of a traction rope, so that the digital quantity signal output end of the tension sensor is connected with the digital quantity input end of the variable-pitch controller through a transmission line. The structure is reasonable in design and can rapidly send a monitored signal of falling of the foreign matters in the wheel hub to the pitch-variable controller so that the pitch-variable controller timely takes measures, thus the safety operation of the wind turbine generator set can be protected.
Description
Technical field
The present invention relates to a kind of wind-powered electricity generation unit operation safety monitoring assembly, 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 in worldwide, promote 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, mostly it 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 great hidden 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.
Summary of the invention
The purpose of this invention is to provide 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 existing technology existence drops; Can't in time prevent the problem that fault takes place, its reasonable in design can send to the signal that the inner foreign matter of the wheel hub that monitors drops rapidly change 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 present invention 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: be arranged between the interior hanger of riveting buttonhole and connecting plate that the foreign body collector that drops in the wheel hub is connected said pulling force sensor through traction rope the place, summit, make the digital quantity signal output terminal of said pulling force sensor utilize transmission line to be connected with the digital quantity input end of said change oar controller.
The said foreign body collector that drops selects for use polytetrafluoroethylmaterial material to process the trigone low temperature resistant, corrosion-resistant, that pull resistance is strong.
The said foreign body collector mounting plane that drops becomes 30～60 degree angles with the fan blade plane of rotation, and make said drop foreign body collector with do not interfere wheel hub after traction rope is connected in the normal operation of other equipment.
Advantage and good effect that the present invention has are: because the present invention is provided with the foreign body collector that drops in wheel hub; And through traction rope with pulling force sensor be connected the foreign body collector summit place of dropping 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 sends signal to and become the oar controller, makes 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 technological existence drops, and can't in time prevent the problem that fault takes place.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a kind of structural representation of the present invention.
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
Specify concrete structure of the present invention 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 through 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 process 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 other equipment in the wheel hub after traction rope 2 is connected.
When having foreign matter to drop in the wheel hub; Owing to receive 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 safe operation that the oar controller will in time take measures to protect the wind-powered electricity generation unit.
Claims (3)
1. the inner foreign matter of the wind generator unit wheel hub monitoring device that drops; Comprise pulling force sensor; Become oar controller and electric control loop; It is characterized in that: be arranged on the foreign body collector that drops in the wheel hub and through traction rope said pulling force sensor be connected the riveting buttonhole at place, summit and be fixed between the interior hanger of the connecting plate in the wheel hub, make the digital quantity signal output terminal of said pulling force sensor utilize transmission line to be connected with the digital quantity input end of said change oar controller.
2. the inner foreign matter of the wind generator unit wheel hub according to claim 1 monitoring device that drops, it is characterized in that: the said foreign body collector that drops selects for use polytetrafluoroethylmaterial material to process the trigone low temperature resistant, corrosion-resistant, that pull resistance is strong.
