Abstract

An axial flow turbine 8, for generating power from wind or water flow, comprises radially extending vanes 1 which are rotatable between two positions around their longitudinal extending axis by the action of fluid flow forces acting on the vanes. The turbine can operate in forward and reverse flows e.g. tidal flow.

Description

Multi-Direction Flow Power Turbine.
The present invention relates to a turbine system in which forward and reverse flowing fluids can be handled in contrast to most conventional turbines,which nearly all are designed for uni directional fluid flows. The system has a number of unique features allowing it to be used in a large number of applications in the fields of renewable wave and windpower;in steam flow
power;hydro-electric power;in industrial combined cycle power;in bigcycle systems and in small size form in various engines for the automotive and shipping industries.
Conventional turbine systems normally are designed for inward flow in the one direction.i.e.uni directional flow.Where the flow is bi-directional as in seawater tidal flow a conventional flow turbine would not be an appropriate choiceTurbines which come into this category are reaction and impulse turbines etc.Other distinguishing features which separate this invention from others will be described in the description which follows.
Itis an objective of the present invention to provide a low cost system to generate low cost power and have the design flexibility to cater for a range of applications in different energy fields.ln
addition overcome the restrictions in the prior art.
The invention provides a turbine for generating power,or for other purposes,in which the inward flow to the turbine can be a liquid,a gas and which the said turbine comprises two stationary shells,one of which is fitted on either side of the turbine wheel each of which houses the generation compnents such as the generator,its rotor and shaft said shaft supported by covered bearings on either side of the turbine wheel said bearing covers fitted with two vertical legs extending downwards to a grouted platfomm on which the said whole turbine is located said turbine wheel fitted with radial vanes around the turbine wheel hub said radial vanes connected to the wheel hub onto small radial shafts so that the radial vanes can rotate around said small radial shafts by the forces of the fluid acting on the vanes said small shafts machined with annular recesses on either side of their outside diameter said radial vanes fitted over the said small shafts with pins extending through the vane into the said annular recesses thus restricting the amount of swivel movement of the radial vanes cross sectional shape of said radial vanes are such that it limits the drag force acting on the vanes at the same time maximising the radial lift force thus optimising the energy efficiency of the turbine governor and electronic control system to control the speed of the turbine within set limits location danger light system fitted on a leg support to warn of danger to approaching craft In a first embodiment of the invention the turbine is located in the sea offshore,or in a river flow.As the tide flows in and out,or the river flows, power is generated 24 hours per day In a second embodiment this is an oscillating water system comprising the turbine wheel located horizontally within a vertical "L" shaped duct so that as a wave enters the duct it flows up through the turbine wheel causing it to rotate thus generating power.Further power is generated when the wave recedes.Thus power is generated during each wave cycle 24 hours per day.
In a third embodiment the turbine wheel is located in a "L" shaped duct supported on a frame above the sea level.As the wave oscillates up and down it forces air up and down through the turbine wheel generating power in the process.
In a fourth embodiment this is as an aero-generator which can be located offshore,or on land,or on a building such as a power station or a house. Multiple turbines can be located on a single support pole offshore or onland.
2. Aspects of the invention become apparent from the following diagrams:

Pig 2 shows the various components of the turbine.The main snare 11 is supported by bearings 3 and 4 at either end ofthe shaft 1 l.The outer stationary shells 6 and 7house the internal rotor and cer._.atv. s"vuiuiny, the Shari i Between the shells is located turbine wheel 8 located internally On the chat 1 Peon,,5,, alAd Sects I. -,l event dialer ingress mto the inner parts of the rotor and generator dunag rotation of the turbine wheel 8.The turbine wheel blades 1 are designed to swivel about their central ems located on a small shaft 2 extended from the wheel hub Sealed bearings 5 are located within the small shad to allow the turbine blades to swivel by the action of sea water or air flowing over them.It this action which causes the turbine wheel 8 to rotate thus generating power. Fig 3 shows an exploded view of the details of the working of the turbine wheel blades 3 located on the small shaRs ( item 2 Fig 2).The centre line of the wheel is at 6 and the arrow indicates the direction of rotation of the wheel.There are two types of the turbine wheel.The first is a free flow turbine without guide vanes 4 and the other is with guide vanes which would be located within a horizontal cylinder surrounding the blades (see Fig 2)with radial supports extending down to the stationary shell diameters 6 and 7.The said guide vanes and radial supports located within the cylinder to the right and left of the turbine wheel.
Reverting to Fig 3 each wheel blade 3 can swivel through an angle limited by two small stops 5.The latter are small screws located on the wheel hub diameter 2 Fig 1.In Fig 3 the cross section shape ofthe blades are of aerofoil shape with the upper surface 2 symetrical about its centre line while the lower surface area 7 is less than 2..en the fluid flows over the blade a lift force is generated which is transmitted to the turbine wheel and its shaft causing them to rotate.When the Dow is from left to right the Dow first flows through the guide vanes 4 on the left, then over the blades 3 before leaving the wheel through the right hand guide vanes 4.When reverse flow takes place such as in tidal flow,this type of flow causes the blades to swivel round between the stops 5 to take up the position shown by the blade 2 with the, ctaticr, d:" action as berore. Thus power is generated no matter the direction of the tidal flow.
En the case of a design ofthe free flow type without guide vanes,the flow enters the turbine wheel and in flovvng over the blades they take up an angular position near to the horizontal mid position between the stops 5. This is because of the balancing flow forces acting on the blades surfaces.
The designs will have a large number of applications including free flow aerogenerators,low in costs and vote high efficiency generating low cost electricity lower than the prior art.
