Abstract
A horizontal-axis wind turbine brake device comprises a tower rod (5), wherein a generator (3) is installed on the tower rod (5), lifting blades (1) are connected with a support (2), and the support (2) and the generator (3) are provided with brake mechanisms. The horizontal-axis wind turbine brake device has the advantages that operation and shut-down are achieved through contacting of a brake disc by means of up-down displacement of a wind wheel of a horizontal-axis wind turbine, the horizontal-axis wind turbine brake device can be applied to a plurality of horizontal-axis wind turbines, and prevents high wind and typhoon from damaging wind driven generators.
Description
Technical field
The present invention relates to technical field of wind power generation, specifically the vertical axis aerogenerator braking device.
Background technique
The vertical shaft-type structure wind-driven generator is fit to be installed in extraordinary building and multiple compensation type generating occasion owing to need not wind mechanism not had too large place restriction, and more wide application is arranged.But wind-driven generator is avoided strong wind, hurricane unavoidably owing to be installed in the more abundant area of minute resource, therefore for safety, the knock-off gear that brakes more reliably must be arranged.So under this background, developed the vertical axis aerogenerator brake system, can be applicable to numerous vertical axis aerogenerators.
Summary of the invention
The purpose of this utility model is a kind of vertical axis aerogenerator braking device that contacts brake disc realization work and shutdown by the vertical axis wind turbine upper and lower displacement of exploitation.This braking device is that the resetting of friction, spring reset mechanism by brake disc, the parts such as traction of electronic tie rod are realized.
The utility model vertical axis aerogenerator braking device comprises: tower bar 5, generator 3 are contained on the tower bar 5, and lift force blade 1 links to each other with support 2, be provided with Sha Che Ji Ju on support 2 and the generator 3.
Described Sha Che Ji Ju comprises: be fixed with brake disc 6 below the support 2, with be provided with lower brake disc 7 on the bearing support 13 on the motor casing 14, the lower end of support 2 axles is fixed with spring capping 10, be pressed on the spring 11, spring 11 is pressed on the spacing end cap 12 in the tower bar 18, and the upper brake disc 6 of support 2 and the lower brake disc 7 on the bearing support 13 have the stroke distances of L.
Fixing with revolution clamping stopper bearing 19 bottom of support shaft, the other end of revolution clamping stopper bearing 19 is fixedly connected with wire rope 20, and revolution clamping stopper bearing 19 can avoid the rotation of wind wheel to drive wire rope 20 loose disconnections, and wire rope 20 lower ends are connected with electronic tie rod 21.
The utility model vertical axis aerogenerator braking device brake is achieved in that and is fixed with brake disc 6 below the support 2 that supports wind wheel (three lift force blades 1), with the lower brake disc 7 on the bearing support 13 stroke distances of L arranged.The axle that support 2 connects oilless bearing 9 interior and in the motor casing lower end cap 17 cooperates, and 2 on wind wheel and support can and can rotate in motor 14 interior free upper and lower displacements.The lower end of support 2 axles is fixed with spring capping 10, be pressed on the spring 11, spring 11 is pressed on the spacing end cap 12 in the tower bar 18, fixing with revolution clamping stopper bearing 19 bottom of support shaft, the other end of revolution clamping stopper bearing 19 is fixedly connected with wire rope 20, the purpose of revolution clamping stopper bearing 19 is to avoid the rotation of wind wheel to drive wire rope 20 loose disconnections, and wire rope 20 lower ends are connected with electronic tie rod 21.When providing signal to electronic tie rod haulage cable and down draw, then wind wheel support 2 is forced to move down, thereby and the upper brake disc 6 of wind wheel support 2 lower ends contact friction brake with lower brake disc 7 on the bearing support 13, reached the purpose of shutting down braking.
The advantage of the utility model vertical axis aerogenerator braking device is: contact brake disc realization work and shutdown by the vertical axis wind turbine upper and lower displacement; can be applicable to numerous vertical axis aerogenerators, exempt to avoid strong wind, hurricane to the destruction of wind-driven generator.

Embodiment
As shown in Figure 1, a kind of vertical axis aerogenerator braking device comprises three lift-type blades 1 of wind wheel that support 2 supports, and support 2 is fixed with upper brake disc 6, can rotate around motor 3, and motor is installed on the tower bar 5.
Shown in Figure 2, support the support 2 of wind wheel (three lift force blades 1), the below is fixed with brake disc 6, but with motor casing 14 on bearing support 13 in linear bearing 8(upper and lower displacement rotatable again) cooperate.Stator 15 is arranged in the motor casing, rotor 16 is arranged in the support shaft, the axle that support 2 connects oilless bearing 9 interior and in the motor casing lower end cap 17 cooperates, and wind wheel then can and can rotate in motor 14 interior free upper and lower displacements so.The lower end of support 2 axles is fixed with spring capping 10, is pressed on the spring 11, and spring 11 is pressed on the spacing end cap 12 in the tower bar 18, and under the effect of spring force, the upper brake disc 6 of wind wheel support 2 and the lower brake disc 7 on the bearing support 13 have the stroke distances of L.Therefore wind wheel support 2 can freely rotate and generate electricity under 1 effect of three lift force blades having in the situation of wind.
Fixing with revolution clamping stopper bearing 19 bottom of support shaft, the other end of revolution clamping stopper bearing 19 is fixedly connected with wire rope 20, the purpose of revolution clamping stopper bearing 19 is to avoid the rotation of wind wheel to drive wire rope 20 loose disconnections, and wire rope 20 lower ends are connected with electronic tie rod 21.When providing signal to electronic tie rod haulage cable and down draw, then wind wheel support 2 is forced to move down, thereby and the upper brake disc 6 of wind wheel support 2 lower ends contact friction brake with lower brake disc 7 on the bearing support 13, reached the purpose of shutting down braking.
