FIELD OF TECHNOLOGY
This invention relates to a Wind machine for enhanced and controllable power generation. Further, this invention relates to a new device to be used with the wind machine so as to increase the power of the wind machine and to regulate its working. More particularly this invention relates to a wind machine for enhanced and controllable power generation.
DESCRIPTION OF RELATED ART
In the existing technology Wind-Machine or Wind Mills are generally of two types:
1) Wind Machine having leaves or blades moving perpendicular to the direction of the wind; i.e. the axis is in the line of action of the force of wind; and
2) Wind Machine having leaves or blades moving in the direction of the wind; i.e. the axis is perpendicular to the line of action of the force of wind.
In the second type, when we say, the leaves moving in the direction of the wind since circular motion, it is understood that there is a half portion of the wind machines, where the leaves move against the wind so as well as the wind pushes forward the leaves in one semi-circular portion, it tries to block the rotation of the leaves in the latter portion. The face of the leaf catching the wind is concave and the other face is convex. So there is a resultant force running the leaves. Yet the blocking hit of the wind in a half portion of the machine is reducing the speed of the leaves, and thereby reducing the power generated.
In the second type of wind-machine currently is in use, no provision is made to avoid the blocking thrust of the wind on the leaves.
Another limitation in the existing wind machines of any type is that no provision is provided to regulate the rotation of the leaves and the speed of the rotation is totally dependant on the wind velocity available at that particular time. Yet another limitation of the present art is the location of the wind machine is restricted to such places where wind velocity is high.
PROPOSED SOLUTION
This invention overcomes the drawbacks in the present wind machine by its unique invention and mechanism whereby it will be able to regulate the rotation of the leaves and increases the power of wind machine.
The present invention is aimed at increasing the concentration of air/wind fallen on concave surface so that the speed of the rotation increases thereby enhancing the total efficiency of the existing wind machine. The inventor has developed a device which is capable of achieving not only the concentration of air/wind on concave surface but also minimising the wind force at convex surface of the blade which otherwise acts as blocking wind thus achieving the overall efficiency of the wind machines. The device according to the present invention has a means of controlling the quantity of wind to be focussed on the concave surface of the blades of the wind machine so as to regulate its speed, which in turn controls the wind energy thus produced.
OBJECTS OF THE INVENTION
The primary object of this invention is to design a novel device fitted with the wind- machines, which is unique.
It is another object of the invention to invent and design a new wind deflector device, which increases the power of the wind-machine.
It is another object of the invention to invent and design a new wind deflector device, which regulate the working of the wind machine; where in, a new method of utilizing wind-power is introduced.
It is another object of the invention to invent and design a new wind deflector device to correct the defects of the present wind-machines with the help of an additional fitting.
It is another object of the invention to design and construct a new wind deflector device, which is economical in construction and efficient in operation.
It is another object of the invention to design and construct a new wind deflector device, which can be used even in low wind velocity such as not less than 3 miles per hour.
Further objects, features and advantages of the present invention will be clear from the following description taken in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTION
This invention teaches the placement of a wind deflector of a suitable size against the second type of wind machine of prior art. The wind deflector as described herein comprises a mouth for collecting and deflecting the wind towards the wind machine and a rear tubular structure to focus the collected wind on the concave surfaces of the leaves or blades of the wind machine.
The size of the mouth is preferably larger than the dimension of the wind machine and the rear end i.e. focussing end (tubular end) covering the first half of the wind machine where the concave surface of the blades or leaves receive the focussed air. The mouth of the deflector blocks the other half of the wind machine and hence no substantial air/wind hits this portion thus making the rotation of the blades unhindered.
The wind deflector is optimally secured to the wind machine or otherwise placed on a stand. The proximity between the wind deflector and the wind machine is as near as possible also as allowed by the actual dimensions and other factors if any.
The area of the mouth of the wind deflector can be altered by adjusting the flaps fitted to the mouth by means of flanges. Hooks are also provided to the flaps to fix their positions for a particular opening area. This mechanism enables to control the wind flow. Because of this arrangement, the wind machine operates efficiently even at low wind velocity. The internal arrangement of the wind deflector and the proximity between the wind deflector and the wind machine is chosen in such a way that the optimum conditions are achieved for better efficiency.
Accordingly, the present invention relates to a wind machine (10) for enhanced and controllable power generation characterized in that a wind deflector (12), optimally secured to the said wind machine (10), arranged in such a manner that blocking wind is converted into helping wind thus enhancing the efficiency of the said wind machine (10); and wherein the said wind deflector (12) such as herein described comprising a means for collecting the wind of a large area including the blocking wind and a means to focus the said collected wind onto the concave surfaces (16)of the blades (16) of the said wind machine (10).

DETAILED DESCRIPITON OF THE INVENTION
The wind machine (10) for enhanced and controllable power generation consists of two integral parts, namely, the windmill (32) and the wind deflector (12). The windmill (32) is of conventional type, which has leaves or blades (14) moving in the direction of the wind; i.e. the axis is perpendicular to the line of action of the force of wind.
The wind-deflector (12) is a funnel - type device. It is fitted in the front of the wind machine (12). The front view cross section of the funnel type device is rectangular. The narrow end of the device has the same outer dimensions as the dimension of the half-portion of the diametrical cross-section of the wind -machine (12). The narrow end is open to the concave face of the leaf (16). There is a rectangular projection of this end, to render the wind straight on the leaf.
The wind machine (10) is adjusted exactly facing the wind. The wind deflector (12) on stand (22) is fitted in front part of it, such that the tail-end is exactly facing the concave face of leaf (16) and the mouth (24) is exactly facing the wind. The hinged flaps (20) at the mouth end are opened and extended to the sides .The position of the flaps (20) are kept at an angle to catch more wind in to the system. Now the wind of a very large area enter the mouth, and is deflected by the sloped side plates (30) and get converged and is led to the concave face (16) of the leaf. Also the convex face (26) of leaf is protected from blocking wind hit. The opposing wind also is deflected and deviated to the concave face (16) converting it to a helping wind. Thus the efficiency of the machine is largely increased.
The mouth (24) of the funnel-type device is so large that it conceals the other half portion of the wind-machine (10). Thus, it protects that half portion from the opposing wind-hit. The sloped side-plates (30) lead the adverse wind to the other half, thus converting it to a helping wind.
The mouth (24) of the funnel (18) is open to a large area, so it catches the wind of a large area, and deflects and converges it on the concave face of the leaf (16), thereby immensely increasing the velocity of rotation.
There are two hinged flaps (20) or doors to the mouth (24). When extended to the sides they increase the quantity of the wind admitted into the machine. When closed, they project at a 'V' shape before the machine. By adjusting the flaps (20), the working of the machine is regulated. So we call the flaps (20) as regulators. The inclination of the flaps (20) is adjusted by two hooks (34).
The wind-deflector (12) is fitted on to a stand (22) firmly. So that it can be mounted on a platform in front of the wind-machine (10). The position of the device is adjusted such that the tail end is exactly in front of the concave face of leaf (16), and such that the whole system is exactly facing the wind.
The wind deflector (12) is firmly fitted on a platform before the wind machine,(10) such that the rear end of the wind deflector (12) is at least 10 cm away from the blades (14) of the wind machine (10).
The Wind deflector (12) is fitted onto a stand (22). The stand (22) has a base of two lengthwise bars and two cross bars connecting them. From the base, one pair of vertical bars is erected to support the mouth end face of the wind deflector (12). Another pair of taller bars is erected to support the rear end face of the wind deflector (12). The vertical bars are connected to the wind deflector (12) by spot welding. The stand (22) is fitted on platform with nuts and bolts.
When 2a and b the length and breadth respectively of the diametrical cross- section (front-view) of the Wind-Machine (10),then the face of the tail-end of the Wind-Deflector (12) has sides a and b, such that it fits correctly to the half portion of the front view of the Wind-Machine (10).
The rectangular projection of the tail-end has length of at least 30cms.
The mouth face of the device has length 3a and breadth b. i.e., the enlargement is only in the length, and the breadth is the same. Therefore the side-plates of the funnel (18) except the rectangular projection have the shape of trapezium and top and bottom plates are rectangular.
Of the side plates, the parallel sides of the trapezium plates are a and 3a.The sloped sides have length aV2, since the angle of tapering is about 45°.
The rectangular plates at the top and bottom have length aV2, and breadth b. The hinged flaps (20) or doors at the mouth (24) are rectangular plates having length 3a and breadth b, so that when closed they stand against the wind making an angle of about 60° between them.
The dimensions mentioned here in the descriptions are merely illustrative and are not to be construed as limiting the scope of the invention. The stand (22) has two lengthwise 2cmx2cm bars of length 130cms.+a they are connected by the same size bars of length b at points 50cms apart from the ends. From the joining points, one pair of vertical bars of same size and of height 50 cms is erected to support the mouth face. Another pair of bars of same size and of height 50cms+a is erected to support the tail end face.
The front view cross section of the half portion of the wind machine (10) is rectangular so the rear end face of the wind deflector (12) is inevitably rectangular. Coming to the mouth end face, we increase only the length, the breadth is kept constant so the mouth end face covers the half portion of the wind machine (10) and symmetrically the mouth extends to the sides. Thus, the mouth end face has the shape of rectangle. This shape is more congenial since the flaps are extending to the other two sides.
The wind deflector (12) is suitably attached to the wind machine (12) either at the stand (22) of the wind deflector (12) or by attaching the deflector itself to the wind machine (10) directly depending on the geographic and other factors which influence the requirement of attachment.
The wind machine (10) is installed in such a place where the wind velocity is not less than 3 miles per hour. Further, the wind machine is installed in such a place where the wind velocity is not higher than 40 miles per hour. In case the wind velocity is higher than 40 miles per hour the wind machine will have to be shut down by closing the side flaps.
Although the principles, preferred embodiment and preferred operation of the present invention have been described in detail herein, this is not to be construed as being limited to the particular illustrations forms disclosed. Various modifications of the disclosed embodiment as well as alternate embodiments of the invention will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore contemplated that such modifications can be made without departing from the spirit or scope of the present invention as defined in the appended claims.
