Abstract

Apparatus for utilising wind power comprises a plurality of sails supported on vertical rotary shaft 11, each sail having a grid like framework with pivoted vanes 24 over its openings 25. Rotation of the vertical shaft by action of the wind on the sails can be used to drive a hydraulic pump supplying a turbine connected to an electric generator. <IMAGE>

Description

SPECIFICATION Use of wind power This invention concerns the use of wind power, particularly in the generation of electrical power, and apparatus therefor.
Wind power has been used hitherto in driving windmillsfor milling and for pumping. These windmills have a plurality of sails rotatable about a central axis in a generallyvertical plane. A disadvantage of such an arrangement is the need for a high tower or the like on which to support the sails, which causes difficulties in construction and maintenance.
This invention seeks to provide apparatus for utilising wind powerthat does not sufferfrom the above disadvantage.
According to this invention there is provided apparatus for utilising wind power comprising a plurality of sails rotatable in a generally horizontal plane.
The sails are preferably supported on a rotatable vertical shaft. The vertical shaft may have its top supported in a bearing which itself is preferably supported bytensionwires or rods. These wires or rods may pass over, and be supported by, thrust columns before being anchored.
The lower end of the rotatable shaft may be arranged to drive a meansforutilisingthewind power that acts on the sails to cause rotation ofthe vertical shaft. That means may be directly or indirectly an electrical power generator. Thus rotation of the vertical shaft could drive a low-speed hydraulic pump that feed a high-speed water turbine coupled to an electrical power generator.
The lower end of the aerodyne shaft may be integral with or keyed to the shaft ofthe low-speed hydraulic rotary pump. The latter possess two vanes on each of which impinges, in turn, a sliding spring-loaded "land" separating the input and output ports ofthe pump. The vanes are cam-shaped to enablethem to move the land sideways into a recess in the side ofthe pump automatically as they rotate past it. The input and output ports are connected by pipe-lines to the central turbine house of the power installation. The output port pipe-line terminates in a nozzle driving the turbine wheel, and the input port pipe-line terminates beneath the surfaceofa sump, or reservoir, below the turbine wheel and fed bythe water discharged therefrom.
The complete power installation may consist of a plurality of apparatus of the invention each supplying its own individual nozzle; where the number is large, more than oneturbine wheel may be mounted on the same shaft. Each apparatus is preferably spaced sufficiently from its neighbours so as not to shadow them which would reduce output.
Each sail may befurthersupported by tension means, such as wires, attached thereto and to an upper part of the vertical shaft andlor by wheels running on the ground or preferably on a track. The sails preferably comprise a plurality of vanes supported on a grid-like framework, the vanes being slung on horizontal members of the grid to hang down one side ofthe sail only. The vanes may be sized largerthan the grid openings so that when blown against they act against the sail framework. Alternatively the vanes may be smallerthan the grid openings but be spring-loaded or counterbalanced so that if the wind velocity becomes dangerously high the vanes can be lifted by the wind to reduce the strain on the apparatus.
Asforthe operation of apparatus ofthis invention, assume a four-sail apparatus with sails A, B, C and D and a wind blowing directly on to sails A and C. Atthis moment sails B and D will be edgewise to the wind.
The vanes of sail A hang down, for example, on the windward side of the sail-grid so that the wind will blowthem againstthe grid-bars,that istheywill remain vertical and therebytransmitthe full force of the wind as a torque on the rotor. However, the vanes of sail C will be swung upwards by the wind away from the grid-bars until they are nearly horizontal so that they will exert little or no torque on the rotor. There will therefore be a large net torque (torque of sail A minustorqueofsail C)to rotate the rotor. As sails B and D come into the wind, the same operations will be repeated on them, and soon.
This invention will now be further described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 showsanapparatusforutilisingwind power; Figure 2 shows detail of the apparatus of Figure 1; and Figure 3 shows a site plan for a plurality of wind power apparatus.
Referring to Figures 1 and 2, wind power apparatus 10 has a rotatable vertical shaft 11 supporting in formation four sails 12. The sails 12 are not only attached directly to the shaft 11 but are further supported by wires 13 from the top ofthe sails to a top part ofthe shaft 11 and pairs of wheels 14 on the bottom of sails running on concentrictracks 15,16.
The shaft 11 has its upper end supported in a bearing 17that is itself supported bytension wires 18 connected thereto and to anchorage points 19 on the ground after passing over inclined thrust columns 20.
The bearing 17 takes no vertical load butservesto keeptheshaftvertical load butservesto keeptheshaft vertical. The lower end of the shaft 11 is integral with or keyed to the shaft of a low-speed hydraulic pump (not shown).
The sails 12 have a grid-like framework of horizontal 22 and vertical 23 members defining openings 25 over which are vanes 24. Each vane 24 is, in fact, slung from the upper horizontal member of its opening 23. The vanes 24 are free to swing upwards when their sail is moving against the wind but act against a spring 26 when the sail is moving with the wind so asto rotate the apparatus. The spring 26 is of such strength that under average wind conditions the vanes will be vertical when acted upon by the wind but will be lifted by stronger winds to avoid undue strain on the apparatus.
Operation ofthe apparatus of Figures 1 and 2 is as described generally hereinbefore.
In Figure 3 a suitabie arrangement of sixteen wind powerapparatus loins shown. Each apparatus 10 drives its own low-speed hydraulic pump that in turn are grouped in fours for driving via pipelines 29 water turbines such as Pelton Wheels 30. The four water turbines 30 together drive an electrical powergenerator31.
Although described in connection with the generation of electrical power, it will be appreciated that the rotary motion ofthe apparatus ofthe invention may be putto other suitable uses.
