Embodiment
A specific embodiment of the mechanical brake equipment of the vertical axis aerogenerator group providing for the utility model as shown in Figures 1 to 5, installs this mechanical brake equipment in the bottom of vertical axis wind turbine.This braking device is made up of drum brake, bindiny mechanism, electric pushrod etc., and wherein drum brake is made up of brake drum 2, fixed underpan 18, brake shoe 15, lever shaft 16, shoe plate rotating shaft 17, rocking arm 9 etc.; Bindiny mechanism by reset tension spring support 11, additional reset tension spring 10, connection bracket 14, connecting steel wire ropes 12, steering linkage member 13, turn to rotating shaft 19, wire rope 3, keep extension spring 4 etc. to form; Draw-off mechanism is a screw mechanism, drive unit is motor, this draw-off mechanism and motor combine and also can be described as electric pushrod, push-rod electric machine, electric cylinder or linear actuators, and electric pushrod is a kind of electric driver that rotatablely moving of motor is changed into the straight reciprocating motion of push rod.
Brake drum 2 is fixedly connected with wind power generator rotor 1, makes itself and rotor 1 synchronous rotary (see figure 1).
The stator center axle 8 of fixed underpan 18 and wind-driven generator is fixedly connected with.
Two adjacent ends of two brake shoes 15 are hingedly fixed in a side of fixed underpan 18 by shoe plate rotating shaft 17, as the rotating center of two lobe brake shoes.
Lever shaft 16 is inserted in the circular hole of opposite side of fixed underpan 18, can rotate freely, and its upper end is a flat wider plate structure, is arranged between two lobe brake shoes 15.
As shown in Figure 4, Figure 5, between two lobe brake shoes, strained by two Returnning springs, and be set between shoe plate rotating shaft and lever shaft, two sides on the thickness direction of the flat wider plate structure in lever shaft 16 upper ends and brake shoe laminating.
Rocking arm 9 is fixedly connected with fixed underpan 18 lower end below that is positioned at of lever shaft 16, and rocking arm 9 outer ends apply after power, and lever shaft 16 produces running torque, makes two brake shoes 15 revolt Returnning spring and open.
The steering linkage member 13 right angle places of modification of right-angled triangle plate shape establish hole connection and turn to rotating shaft 19, by turning to rotating shaft 19 to be connected in connection bracket 14, steering linkage member 13 can be around turning to rotating shaft 19 to rotate, two other drift angle end of steering linkage member 13, near rocking arm 9 be front connecting end, away from rocking arm 9 is rear connecting end.
Reset tension spring support 11 is also fixed on the flange of stator lower end stator center axle 16.On reset tension spring support 11, connect one end of additional reset tension spring 10, the other end connecting rocker arm 9 of this additional reset tension spring 10.
The front connecting end of one end of steering linkage member 13 is connected to reset tension spring support 11 by additional reset tension spring 10; The rear connecting end of steering linkage member 13 by wire rope 3, keep upper end that extension spring 4, wire rope 3 ' be connected in series to electric pushrod 5 movably on push rod 51.Electric pushrod 5 is fixed on shaft tower 7 by anchor ear 6.
When braking, give electric pushrod 5 with electric power, the motor of electric pushrod 5 shortens electric pushrod towards a direction rotation, and tense wire rope 3 ', 3, keeps extension spring 4 to extend.In the time that electric pushrod 5 shortens to certain length, keep extension spring 4 also to extend certain distance, thereby make on wire rope 3 ', to there is certain pulling force, this pulling force is by 13 original downward pulling force of steering linkage member, become horizontal pull, and overcome the pulling force of additional reset tension spring 11, make rocking arm 9 drive lever shaft 16 to rotate in the horizontal direction; The top of lever shaft 16 is a flat cuboid, and it can strut brake shoe 15 after rotating, and the rotating center of brake shoe 15 is shoe plate rotating shaft 17; After brake shoe 15 struts, the outer rim of brake shoe 15 expands, and makes brake shoe 15 brake drum 2 fixing with wind power generator rotor with outside and synchronous rotary contact and rub; After, electric pushrod 5 continues to foreshorten to shorter length, keep extension spring to continue to extend, pulling force on wire rope 3 ', 3 progressively increases, by bindiny mechanism, the moment on rocking arm 9 and lever shaft 16 is increased, the extruding force of brake shoe 15 and brake drum 2 rises, thereby frictional force is increased, produce certain braking force; Along with electric pushrod 5 arrives default shortest length, drum brake also produces certain braking moment, makes wind-driven generator.
In the time will removing wind-driven generator, the motor of electric pushrod 5 rotates in the opposite direction, electric pushrod 5 extends, make to keep extension spring 4 lax, pulling force on wire rope 3 ', 3 reduces, the pulling force that additional reset tension spring overcomes connecting steel wire ropes makes also motion in the opposite direction of rocking arm 9, and the extruding force between brake shoe 15 and brake drum 2 reduces until be entirely zero after throwing off, braking moment also along with progressively reducing until be zero.
Above braking device and the braking method of novel the provided a kind of vertical axis aerogenerator of this use are had been described in detail.To those skilled in the art, under the prerequisite that does not deviate from connotation of the present invention, the utility model is made to multiple change, clearly, these changes all will fall in the scope of the utility model patent right.
