Abstract

The invention discloses a wind driven generator stopping mechanism, mainly comprising a steel wire rope and a stopping mechanism, wherein the stopping mechanism comprises a stopping support in which an electromotive push rod is fixed; the expansion end of the electromotive push rod is connected with the steel wire rope; and the electromotive push rod drags the steel wire rope to move up and down so as to drag the brake in the wind driven generator, which plays the role of electromotive brake. The wind driven generator stopping mechanism is simple in a main body structure and safe, reliable and practical. Stopping by manpower is achieved when the electromotive function does not work or other emergent situations occur. The stopping mechanism realizes the integration of electromotive and manual stopping mechanisms of a small and medium wind driven generator stopping actuator and can be freely dismantled.

Description

Wind driven generator stopping mechanism
Technical field
The present invention relates to wind-driven generator, especially a kind of wind driven generator stopping mechanism.
Background technique
Because the wind-driven generator Environmental Conditions is more abominable, in strong wind,, need usually to shut down in order to protect the safety of wind-driven generator.And existing middle-size and small-size wind-driven generator main frame does not generally have reliable stop mechanism or the general manually stop mechanism that adopts easily, can not realize electronic parking.
Summary of the invention
The objective of the invention is provides a kind of simple and compact for structure for the deficiency that solves above-mentioned technology, can realize the incorporate wind driven generator stopping mechanism of electronic and manual parking.
In order to achieve the above object, the wind driven generator stopping mechanism that the present invention is designed, it mainly comprises wire rope and stop mechanism, and stop mechanism comprises parking bracket, and the parking bracket internal fixation has electric pushrod, and the flexible end of electric pushrod is connected with wire rope.Move up and down by the electric pushrod haulage cable, thereby the effect of electric brake is played in the brake in the drawing wind power generator.
The electric pushrod lower end connects with hanging to tie, and hangs between the inwall of bolt and parking bracket and is provided with stage clip, and the bottom of hanging bolt is passed parking bracket and reached the parking bracket outside, and is provided with knob.By manually carrying out the turn knob, electric pushrod and wire rope are moved down together, the effect of manual brake is played in the brake in the pulling electric generator.
Parking bracket is by being bolted on the mounting bracket, and mounting bracket is fixed in the tower bar, makes things convenient for the dismounting of stop mechanism.
The resulting wind driven generator stopping mechanism of the present invention, agent structure is simple, safe and reliable practicality.The electric pushrod of vertical motion has been installed, has been realized the function of electronic parking, and action delay is few, is quick on the draw, can be under various emergency situations timely stop-working protection blower fan.During malfunctioning or other urgencies, can realize artificial parking when electric functions.This stop mechanism has been realized electronic and manual stop mechanism integrated of middle-size and small-size wind driven generator stopping mechanism, and this stop mechanism can freely be dismantled.

Embodiment
The invention will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the wind driven generator stopping mechanism that present embodiment is described, it mainly comprises wire rope 1 and stop mechanism 13, the brake of wind-driven generator links to each other with an end of wire rope 1, stop mechanism 13 comprises parking bracket 4, parking bracket 4 internal fixation have electric pushrod 6 as shown in Figure 2, and the flexible end of electric pushrod 6 is connected with wire rope 1.Move down by electric pushrod 6 haulage cables 1, thereby the effect of electric brake is played in the brake in the drawing wind power generator.
Electric pushrod 6 lower ends with hang bolt 10 and be connected, hang between the inwall of bolt 10 and parking bracket 4 and be provided with stage clip 9, the bottom of hanging bolt 10 is passed parking bracket 4 and is reached parking bracket 4 outsides, and is provided with knob 11.By manually carrying out turn knob 11, electric pushrod 6 and wire rope 1 are moved down together, the effect of manual brake is played in the brake in the pulling electric generator.
Hang bolt 10 structures as shown in Figure 3, its lower end is a screw rod, the screw-thread fit of its screw thread and knob.
In the using process; when controller need be shut down by the abnormal conditions that detect blower fan; controller provides signal enabling electric pushrod 6; electric pushrod 6 shortens; haulage cable 1 moves down; the brake of wind-driven generator makes its shutdown under the traction of wire rope 1, electric pushrod 6 carries position limit switch, can quit work automatically behind the arrival stroke.When needs are started shooting, electric pushrod 6 elongations, wire rope 1 discharges, the blower fan start.During malfunctioning or other urgencies, can manually carry out turn knob 11 when electric functions, electric pushrod 6 and wire rope 1 be moved downwards together, until shutdown.
Embodiment 2:
As shown in Figure 4, the wind driven generator stopping mechanism that present embodiment is described, parking bracket is connected with mounting bracket 5 by bolt, and mounting bracket 5 is welded on tower bar 12 inboards, and parking bracket can freely be dismantled.
