This invention is about the technology of generating power continuously from the wind energy.

BACKGROUND OF THE INVENTION

The wind energy is a non-conventional source of energy. Such energy is extracted by the wind mills wherein the energy obtained from wind velocity is converted into electrical energy. The wind power generation purely depends on the location and average wind velocity of the particular region. The wind mills are normally installed at places where the wind velocity is more and consistent. Such mills are robust in construction which requires huge investments. The constraints like wind velocity, location, robust construction, huge investments restricts the establishment of wide wind farms. An attempt has been made in this invention to make the wind mill technology and its installation free from the above constraints.

OBJECT OF THE INVENTION

This invention aims to develop a wind mill in which the wind energy is obtained all throughout the year without any constraints. The said wind mill will function independent of the wind velocity and the location. The cost of production and installation of the said wind mill will be less when compared to the presently available wind mill equipments. The wind movement in any direction will be captured by this wind ^* mill and the energy is generated. The said wind mill will have easy installation capability on any building such that it can serve the domestic as well as industrial purpose. Such simpler wind mill reduce the infrastructure cost.

DESCRIPTION OF THE INVENTION

The wind energy generating apparatus comprises of a four pillar base structure with a spindle arrangement fixed in between the pillars. The said spindle arrangement carries the wind fans such that atleast one wind fan per direction is mounted on the spindle arms. The wind fans with the blades are coupled with the generator unit such that the voltage generation takes place whenever there is a movement of the blades. The wind fans are fixed in the arms with or without enclosures. The enclosure is such that they cover the periphery of the fans or fan blades. The spindle arrangement also includes a commutator like l arrangement such that the voltage generated in the wind fans is instantaneously tapped. Such tapped voltage is stored in battery bank. The said spindle arrangement carrying the wind fans is rotated by a motor coupled to it. The direction and speed of rotation of the spindle is controllable by adjusting the motor speed. Such voluntary spindle movement by the motor will lead to the rotation of the blades in the wind fans even in the absence of the natural /regular wind movements. An artificial wind movement is created by the spindle rotation on the wind fans. The natural wind movements, if present, along with the artificial wind movement created by the spindle movement will make the wind fans rotate to the rated rpm thereby generating the voltage. Differential spindle movement is achievable by controlling the spindle motor speed. In the absence of natural wind movements, the spindle can be rotated to the required speed to achieve the rated speed in the wind fans. In any case, the rated voltage generation is possible by adjusting the spindle rotation. Voltage regulator arrangement ensures proper voltage is fed to the battery storage units. The voltage output from each of the wind fans mounted in the arms of the spindle is obtained in the commutator like arrangement and is clubbed to obtain the desired voltage levels to. be stored in the battery bank. Initially, the spindle motor is operated by a battery supply. Once, the voltage generation picks up in the wind fans, thereupon, the spindle motor is fed from the generated voltage. Suitable arrangement to feed the spindle motor from the generated voltage is made such that the voltage requirement for motor operation is met from the generated voltage.

The term "wind mill system" is used synonymously to "wind energy generating apparatus" throughout this specification. In fig 1 , a spindle arrangement (B) is fixed in between the pillars Of the wind mill base structure (C). The wind fans (1 ,2,3,4) are mounted on the spindle arms (A) with atleast one wind fan per direction . The blades of the fans are coupled with the generator unit (1G,2G,3G,4G) such that the voltage generation takes place whenever there is a movement of the blades. The wind fans are fixed in the arms with blade enclosures (1 E, 2E, 3E, 4E). The enclosure is such that it covers the periphery of the blades. A commutator like arrangement (6) is fixed with the spindle such that the voltage generated in the wind generators (1G, 2G„ 3G, 4G) can be instantaneously tapped. The battery bank (BAT1 , BAT2, BAT3, and BAT4) is arranged to store the energy generated from the wind fans. The spindle carrying the wind fans is rotated by a motor (5) coupled to it through a gear arrangement (D).

The spindle arrangement (B) has a base structure supported with pillars. The spindle with the arms carrying the wind fans and generators is mounted on the base structure. In Fig 1 , for illustration purpose, four arms are shown mounted on the spindle. The arms of the spindle extends from the body of the spindle parallely to the base structure and are mounted perpendicularly to the axis of the spindle facing four directions. The arms shall be at least two and can be mounted at any angular position to the axis of the spindle. The angular position of the arms with the axis of the spindle is arrived based on the wind velocity in a particular location. The length of the arms in the spindle is selected to be high such that the centripetal force is less. The spindle is rotated by a motor through a step down gear arrangement.

The spindle B is made to rotate by operating the motor (5). The direction and speed of rotation of the spindle can be varied by controlling the motor. This spindle/ arms rotation creates artificial wind movements giving rise to rotation of the blades in the wind fans even in the absence of the natural wind movements. Such rotation of the spindle makes the fans rotate thereby rotating the generator to the rated rpm generating the required voltage. The natural wind , if present, adds to the rotation of the blades. Differential spindle movement is achievable by controlling the spindle motor speed. Even in the absence of sufficient natural wind movements, the spindle is rotated to the required speed to achieve the rated speed in the wind fans for voltage generation. The spindle movement alongwith the minimal natural wind present aids for rotation of the wind generators to the rated rpm. In addition, A wind velocity sensor (12) for checking the velocity of the natural wind is used. If the velocity of the natural wind is not sufficient to achieve the rated speed in the wind generators, the sensor operates the motor (5) through a sensor control circuit (13) to rotate the spindle.

The voltage output from each of the wind fans mounted in the arms of the spindle is obtained in the commutator (6) like arrangement and is clubbed to obtain the desired voltage levels to be stored in the battery bank. The generated energy is stored in the batteries through a battery charger circuit (7). The wind generators may be AC or DC generators. If alternators are used as wind generators, the ac voltage generated is obtained through the commutator arrangement and made to charge a first set of condensers (10A)through a change over system (8). Then, the first set of condensers is connected to a converter (9) for converting AC into DC. When the first set is in contact with converter, a second set of condensers (10 B) is connected through a change over system to the generated output. The changeover system is employed to separate the first and second set of condensers thereby separate the generation side and load intermittently. The change- over is operated such that there is a continuous shifting between first & second sets of condensers & regular supply of voltage in the circuit. The converted DC voltage is then filtered and fed to a charger unit (7) for charging the batteries or directly connected to a load through an inverter.

To initiate rotation, the spindle motor is operated by a battery supply. Once the voltage generation picks up in the wind fans, thereupon, the spindle motor is supplied from the load voltage. When two or more wind energy generating apparatus are installed, then output voltage from one of the generating apparatus can be utilized as supply voltage to the spindle motor of the other neighboring apparatus. By this way, the generating apparatus become self -sufficient to feed the spindle motor. The spindle motor is selected such that it consumes less energy than the generated power.

In fig 3, a wind fan is shown. The wind fan has blades and enclosure. The generator unit is coupled to the wind fans. These wind fans are fitted to each arm of the spindle at the edge. Fig 5 shows the wind mill system with the input, generation and output stages.

An alternative embodiment of the invention is shown in Fig 4. In this embodiment, the arrangement of the wind energy generating apparatus is such that the spindle with arms is mounted on the base structure with the generator (G) coupled to the spindle. The generator is either directly coupled or through a gear mechanism to the spindle. The fans are mounted on the arms of the spindle. At-least two fans, each mounted on the arms are fitted in opposite directions. The arms are fitted either perpendicular to the axis of the spindle or fitted at an angle to the spindle. The fans are rotated by the motor (1 M, 2M) fitted to each one of them. Once rotation starts in oppositely fitted fans, the spindle starts rotating thereby rotate the generator. The fans rotate thereby creating a wind movement which makes the spindle rotate. Based on the required rated speed of the generators, the speed of rotation of the spindle is increased either by increasing the fan speed or by fitting additional fans on further arms of the spindle. The fans are given supply from input batteries. Once the required voltage generation is achieved, the fans can be supplied from the output voltage obtained. This wind mill arrangement can be made to suit any application, domestic or industrial purpose. This arrangement also finds its application in boats.
