Abstract
The invention discloses a wind driven generator speed limiting device, and belongs to the technical field of power equipment. The device consists of a brake disc and a centrifugal brake, wherein the centrifugal brake is arranged in the brake disc and comprises a circular bottom plate and three cambered brake sheets; a connecting shaft groove is formed in the center of the circular bottom plate; the three cambered brake sheets are movably connected to the bottom plate; cambered edges of the three cambered brake sheets form a circle which is concentric with the outer circle of the circular bottom plate; each brake sheet is provided with two through holes respectively; and a tension spring is arranged between two adjacent through holes of two adjacent brake sheets. Through the device, the safety of a product is improved, the mounting, maintenance or replacement is extremely convenient, and after-sales service cost and mounting cost of a manufacturer are greatly reduced; compared with an electronic speed limiting device, the device has a more direct effect, does not depend on the functions of other components and has high stability, and the safety is completely guaranteed; and the device is arranged in a fan without affecting the appearance.
Description
Technical field
The invention belongs to electrical equipment technical field, be specifically related to a kind of speed limiting device of wind-driven generator.
Background technique
For a long time, small-sized wind power generator exists bigger potential safety hazard always, when meeting with high wind, and the small-sized wind power generator high speed rotating, produce huge centrifugal force, be easy to cause blade to fly out, along with the raising of rotating speed, the passing rate of wind by blade the time significantly reduces simultaneously, it is big that the blast that blade bore becomes, cause the bending blade distortion, even fracture, cause security incident probably.
At above situation, present a part of small-sized wind power generator is integrated electronic speed limit device in controller, utilize electronics standby current or voltage, control rotating speed indirectly, yet find that in use the rate of fault of controller is higher relatively, in case therefore circuit breaks down, electronic brake system,electronic antiskid system just lost efficacy, and caused wind-driven generator out of control.
Summary of the invention
The objective of the invention is: overcome existing small-sized wind power generator safety problem, remedy the shortcoming of electronic speed limit stability of a system difference, a kind of safe wind-driven generator speed limiting device is provided.
The object of the present invention is achieved like this: a kind of wind-driven generator speed limiting device, constitute by brake disc and centrifugal brake, and centrifugal brake is arranged in the brake disc; Described centrifugal brake comprises a circular bottom plate and three arc brake sheets, the circular bottom plate center is provided with the connecting shaft groove, described three arc brake sheets are movably connected on the base plate, and a circle concentric with the cylindrical of described circular bottom plate is formed on the arc limit of described three brake blocks, offer two through holes on the described every brake block respectively, between adjacent two through holes of adjacent two brake blocks extension spring is set.
The invention belongs to mechanical control method, form by centrifugal brake and two parts of brake disc, wherein centrifugal brake is connected with the main shaft of wind-driven generator, brake disc then is fixed on the casing, drive the brake disc rotation by main shaft, when wind speed becomes big, rotating speed improves, it is big that centrifugal force becomes, utilize centrifugal force to throw brake block away, when wind-driven generator reached the maximum safe speed of rotation of design, brake block contacted with brake disc and produces frictional force, the containment rotating speed further promotes, thereby reaches the purpose of speed limit.Comparing the electronic speed limit device controls rotating speed indirectly and compares by detecting generator charging voltage or electric current, the advantage of this device is its stability, directly be connected, fundamentally limit rotating speed, and the realization of speed limit function do not rely on other parts with rotary main shaft.
Advantage of the present invention is as follows: improved security of products, and no matter installation, maintenance or replacing, all very convenient, significantly reduced the after service cost and the installation cost of production firm; Compare the electronic speed limit device, act on more directly, and do not rely on other functions of components, good stability, safety thoroughly is guaranteed; Be installed in blower fan inside, do not influence outward appearance.
