Description
Technical field
The present invention relates to the aid system of a kind of vertical hydrogenerator.
Background technology
Hydrodynamic bearing in the hydraulic generator of power station, commonly used split sleeve bearing also uses steam turbine oil to lubricate, when axis of rotation is to certain speed, plane of rotation produces one layer of oil film and reduces rotating shaft coefficient of friction between bearing shell, thus reduce abrasion and lower caloric value.During generator driven water turbine is by the shutdown that generates electricity; owing to hydraulic turbine flywheel inertia is bigger; add and often have the phenomenon that current can not shut completely; so flywheel the long period can keep low-speed running when shutting down; during low-speed running, the oil film on bearing shell can not be formed, if overlong time, can damage bearing shell, so during generating is shut down; when Speed of Reaction Wheels drops to a certain degree, it is necessary to take brake measure to make flywheel stop operating as early as possible.The brake of small hydropower station in the past, is all that the workman of generating is put on flywheel limit with wood, prizes the outer rim of flywheel inward, utilize flywheel outer rim to be stopped by flywheel with the frictional force of wood, often could be checked completely by flywheel sled a few minutes by a people or many individuals.On the one hand so brake requires height to labor strength with number, on the other hand power station automation is run transformation and brings a difficult problem.
Summary of the invention
It is an object of the invention to provide a kind of vertical hydrogenerator brake gear, it utilizes electronic, and circuit controls and mechanical mechanism realizes, and power station hydraulic turbine generator brakes.
The technical scheme that the present invention implements is a kind of vertical hydrogenerator brake gear, including power part, driving section, brake portion, power part includes reducing motor, driving-chain, sprocket wheel, it is characterized in that: driving section includes screw rod, chain pulley seat, transmission stock, mobile plunger, buffer spring, promote post, screw rod outer end passes sprocket wheel, sprocket wheel has internal thread supporting with screw rod, sprocket wheel drives screw rod to rotate, screw rod inner end is connected with mobile plunger, sprocket wheel is rack-mount by chain pulley seat, sprocket wheel can rotate relative to chain pulley seat, when sprocket wheel rotates, screw rod enters, or exit transmission stock；Transmission stock one end is connected with chain pulley seat, and in transmission stock mounting bracket, mobile plunger connects buffer spring, buffer spring connects promotion post, promotes post to be connected brake portion brake linkage by adapter；Equipped with bolt on mobile plunger, transmission stock having locating slot, mobile plunger motion drives bolt to move along locating slot；Bolt is provided with and touches sheet, and on carrier base, left and right is respectively provided with an impact switch, and impact switch connects control centre；Brake portion includes lever, brake horse, brake block, brake horse is connected with lever by connecting bolt, brake horse can rotate around connecting bolt, brake horse both sides set limit pull rod, the pull bar other end by spiro cap on lever, make brake horse swing to be in safe spacing, do not cause stuck or scratch flywheel because brake frame rotation amplitude is excessive；Brake block is arranged on brake frame, and adapter is also equipped with two back-moving springs, makes lever lever when promoting post thrust to disappear reset, and brake block and hydraulic turbine divided flywheel dissociation are except brake.
During use, reducing motor rotarily drives sprocket wheel rotation, screw translation is made to promote mobile plunger, mobile plunger promotes spring-compressed, spring forces catch bar, catch bar promotes lever to rotate around fixing end, drives brake block to move compressing hydrogenerator flywheel, realize brake, now on mobile plunger, the sheet that touches on bolt moves until colliding impact switch, and impact switch communicates information to control centre, and notice stops reducing motor and rotates.During releasing of brake, reducing motor reversion band movable sprocket rotates, and makes screw rod unclamp mobile plunger, and buffer spring unclamps, and brake linkage, under action of reset spring, is retracted by catch bar, and brake block unclamps hydraulic turbine flywheel；Moving to when colliding impact switch when touching sheet on mobile plunger drive bolt, impact switch communicates information to control centre, and notice stops reducing motor and rotates.
The beneficial effects of the present invention is: simple and practical, material easily obtains, with low cost；Well instead of Manual braking, it is to avoid artificial brake brings security incident, overcomes existing brake system brake block stuck, scratch flywheel, and can realize remotely controlling.This brake is mainly used in vertical hydrogenerator brake.
Hereinafter with specific embodiment and accompanying drawing, the invention will be further described.
