Description

Elastic Windmill Wind Direction Adjustment Control Mechanism

technical field

The utility model relates to a windmill steering control device, which is especially suitable for a small horizontal axis windmill system.

Background technique

The existing small horizontal axis windmill wind direction adjustment mechanism can work normally within a certain wind speed range, but when the wind speed exceeds a certain limit, the wind direction adjustment mechanism will self-lock, and the windmill will stop working. , although the windmill has been protected from high wind damage, the wind energy during high winds has not been effectively utilized. In addition, after the self-locking occurs, the windmill needs to be released manually before the windmill can resume work. Therefore, this mechanism is not suitable for remote areas and unattended working environments.

Contents of the invention

In order to overcome the disadvantages of the existing windmill wind direction adjustment mechanism, the utility model provides an elastic windmill wind direction adjustment control mechanism. It can also effectively utilize the wind energy during strong winds to realize the unattended work of the windmill.

The technical solution adopted by the utility model to solve the technical problem is: the windmill tail and the wind wheel are eccentrically arranged on both sides of the vertical shaft of the gearbox rotation center, and a tapered roller bearing is installed between the vertical shaft and the gearbox to make the gearbox run on the vertical shaft flexible. The empennage, the empennage push frame and the buffer device are connected to the gearbox through the empennage pin, one end of the buffer device is fixed on the empennage, the other end is supported on the side wall of the gearbox, one end of the elastic tensioning device is connected to the empennage, and the other end is fixed On the side wall of the gearbox, the tail pusher is connected with the tail and can rotate synchronously. The brake arm is fixed on the gearbox by the brake arm pin and can rotate freely. The tail push frame and the brake arm are connected by a push rod. The brake arm pin and the tail pin are symmetrical about the vertical axis. The tail push frame is connected with the The empennage and the brake arm can rotate in the same phase. The upper ends of the two poles are respectively connected with the tail push frame and the brake arm, the lower ends are connected with the push plate, the brake pads surround the periphery of the wind wheel hub, the lower ends are fixed on the side wall of the gearbox, and the brake lever springs are connected with the brake pads. The buffer device is composed of a buffer rod, a buffer spring, a buffer sleeve and a buffer sleeve plugging cover, and the elastic tightening device is composed of a pull rod I, a tightening sleeve, a tension spring, a tightening sleeve blocking cover and a pull rod II.

The beneficial effect of the utility model is that the optimum windward angle of the windmill windmill can be automatically adjusted, and the speed of the windwheel can be effectively reduced when the wind is strong, preventing damage to the windmill by the strong wind and realizing unattended operation of the windmill.

Detailed ways

When the windmill is under the wind condition of the rated wind speed, the empennage 1, the elastic tensioning device 2, the buffer device 3, and the wind wheel 13 are in a relatively balanced state, and the windmill works stably.

When the wind is high, the wind wheel 13 and the empennage 1 are relatively deflected around the vertical axis 7, the tension spring 23 in the elastic tension device 2 connected to the empennage 1 is compressed, the elastic tension device 2 is elongated, and the empennage 1 and the empennage push frame 9 Rotate around the tail pin 4, the tail push frame 9 pushes the push rod 5, and drives the brake arm 6 to rotate around the brake arm pin 8, the brake arm 6 presses the brake lever 19, pushes the brake pad 20 to generate displacement, and hugs the wind wheel 13 hubs reduce the rotating speed of the wind wheel 13 to realize the adjustment of the speed reduction of the wind wheel and the windward angle of the wind wheel.

When the wind speed decreases rapidly, the empennage 1, the empennage push frame 9 and the brake arm 6 rotate rapidly under the action of the elastic tensioning device 2, and the buffer rod 14 in the buffer device 3 compresses the buffer spring 16, avoiding the impact of the buffer rod 14. And the direct impact of buffer sleeve blocking cover 17 and gearbox 12 has protected whole system.

When the system needs to stop running, push the push plate 11 upwards, one pole 10 pushes the empennage push frame 9, drives the empennage 1 to rotate around the empennage pin 4, and the other pole 10 pushes the brake arm 6 around the brake arm pin 8 Rotate, the brake rotating arm 6 compresses the brake lever 19, promotes the brake pad 20, and the wind wheel 13 is stopped.
