Abstract

The top section of the deflector B is cut away to 180 DEG thus exposing the rotor to the wind. Changes in the wind direction reposition the defector by means of a fin "D", the deflector pivoting around the base by means of needle roller bearings. The machine is stopped and started by a sliding skirt which is incorporated within the deflector. This skirt can be operated manually or by a centrifugal trip device in the event of the machine overspeeding. A flange mounted base "C" incorporates the electrical generator F, and the bearing housing for the drive shaft, which is free to rotate in two sets of bearings. Attached to the drive shaft is the multi bladed rotor "A". A locking pin H secures the machine via a hole in the deflector and a location hole in the base of the machine. <IMAGE>

Description

SPECIFICATION Vertically Mounted Wind Generator This invention relates to a wind driven generator.

The wind driven generators that are commercially available at the present time are off a propeller driven type. Because of this, a large area of floor space is required, not only for the rotation of the propelier blades, but to facilitate any change in wind direction.

According to the present invention, the design is to be more compacked and streamline when in operation and during it's shut down.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing's in which: Figure 1 shows a cross section of the base of the machine Cand a side elevation of the rotorA and wind deflector B and positioning fin D.

Figure 2 shows a plan view of the rotor. Blade's A and the sliding skert Ealso the area of rotor covered by the wind deflector.

Referring to the drawing, the machinary consists of a vertically mounted multi bladed rotor A driving a generator Fvia a drive shaft G off which can rotate within two sets of bearings. The wind deflector B which pivots around the base of the machine Cvia two sets Qf needle roller bearings is equipped with a fin D so that it is always positioned by the wind direction as shown in Figure 2.

The purpose of this deflector is to shield the on coming rotor blades from the force of the wind, when in it's running position 1800, therefore the only blades exposed to the wind are rotating in the same direction as the wind. As the wind direction changes so the fin D repositions the deflector.

If the machine is to be shut down the deflector is complete to a cylindrical shape 360" by a sliding skert Ewhich slides around the inside of the deflector, both of which are covered in at the top to stop the ingress of any foreign bodies. This skert shields the rotorfrom the force of the wind, and in this position a pin H locks the deflector to the base of the machine.

CLAIMS 1. A wind driven generator comprising of a vertically mounted, multi bladed rotor. Around which a deflector covering 1800 of the blading, pivots around the base of the machine.

2. Awind driven generator as claim 1 wherein the deflector is provided with a fin to position the deflector according to the wind direction.

3. A wind driven generator as claim 1 and 2 wherein the deflector is provided with a sliding skirt which in it's running position is incorporated within the deflector. If the machine is shut down, the above mentioned skirt slides around the rotor blades, thus shielding the blades from the force ofthetwind.

4. A wind driven generator as claim 1 to 3 wherein the sliding skirt can be operated manually, or in the event of the machine overspeeding can be operated by a centrifugal trip device.

5. A wind driven generator as claim 1 to 4 wherein a looking pin will secure the deflector to the base off the machine, thus preventing any movement, should the wind direction change while in it's shut down position.

6. A wind driven generator as claim 1 to 5 wherein the above mentioned deflector and skirt are covered in at the top, to prevent the ingress of foreign bodies while the machine is shut down.
