Field of invention This invention relates to a cycle operated water lifting device. Specifically this invention relates to a manually driven water lifting device. The device is useful for pumjDing water from rivers, ponds, wells and the like water sources, thus enabling the poor farmers for pumping water for example for irrigation purposes. Background of invention A cycle based water lifting device is known in the art. The device comprises a rope adapted to be passed over the back wheel of the cycle. A pulley is provided within the water so as to keep the rope in a tight and movable position. The rope is pulled upwardly by pedalling the cycle at a high speed and thus the water is lifted up. Another bicycle operated pump is known in the art which comprises a pulley mounted on a pedal shaft of a bicycle. The pulley is adapted to be connected with the pulley mounted on the shaft having a second pulley provided thereon. Means are provided to operate the water lifting pump through the second pulley mounted on the shaft upon pedalling by the user. A water lifting device adapted to be operated by pedalling and by motor is disclosed in the US patent number US6210125 B1. The pump comprises a fly wheel mounted on an axle and adapted to be rotated by means of a chain and sprocket assembly. The chain and sprocket assembly is operated by the user by pedalling. The piston assembly of the reciprocating pump is connected to a cam assembly mounted on the same shaft on which the flywheel is mounted. The cam assembly is provided to provide reciprocating movement to the piston assembly of the water lifting pump. An electric motor is provided to operate the device in case the user feels tired and electricity is available. There are disadvantages associated with the prior art. One of the main disadvantages is that the water out put of the pump is very low and to increase the water output the pedalling is done at a very high speed which is not advisable for the user. Another disadvantage is that in the conventional water lifting device is not so efficient and a lot of input energy is required to lift small amount of water as the device is directly connected to the water lifting means. Yet another disadvantage is that the conventional devices are useful for lifting water from the wells and bore wells only. Still another disadvantage is that the user is not able to apply maximum force during operation of the device as he has to operate the device in the sitting condition only and no means are provided to give support to the user during operation. Objects and advantages of the present invention Therefore, the main object of the present invention is to provide a water lifting device wherein minimum input energy is required to get the maximum output of the water. Another object of the present invention is to provide a water lifting device having the means to reduce the input energy so that the user does not get tired in a short time period. Yet another object of the present invention is to provide a water lifting device which is easy to operate and the pedalling means are not directly connected with the water lifting means/pump. still another object of present invention is to provide a water lifting device which can be used to lifting water from all kind of water sources like river, wells, bore wells, and ponds etc. Another object of the present invention is to provide a water lifting device which can be transported easily from one place to another place. The following description contains many specifics; these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many other variations are possible, accordingly the scope of the invention should not be limited to the embodiment illustrated, and the alterations and variations may be treated within the spirit and scope of this invention. Summary According to this invention, there is provided a cycle operated water lifting device comprising a cycle rim/flywheel mounted on the shaft being supported on the main frame of the device such that to be rotated by the rear rim of the cycle through a belt upon pedalling the bicycle, a second cycle rim being mounted on said first shaft for providing motion to a small cycle rim mounted on the second shaft being supported on said main frame through the respective belt, a third cycle rim being mounted on said second shaft such that to provide rotational movement to the pulley of a water lifting pump through the respective belt to facilitate the lifting of water. Brief description of invention In accordance of this invention water lifting device has a cycle rim/flywheel mounted on the first shaft which is supported on the main frame of the device by means of bearing assembly provided on either sides of the first shaft. The rim gets rotational motion from the rear rim of the cycle by pedalling the cycle by the user. A second cycle rim is mounted on first shaft for providing the rotational motion to a small cycle rim mounted on the second shaft supported on said main frame. A third cycle rim is mounted on the second shaft such that to provide rotational movement to the pulley secured with the main shaft of the water lifting pump. According to an option the device has pair of rims mounted on the first shaft supported on the lower side of the main frame. A flywheel along with big and small rims is mounted on the second shaft which is supported on the top of the main frame. A big and small rim is mounted on the third shaft supported on the lower side of the main frame of the device and towards the water lifting pump. Detailed description of invention A cycle operated water lifting device according to the preferred embodiment of this invention is herein described and illustrated in the accompanying drawings wherein; Fig 1 shows the perspective view of the device Fig 2 shows the perspective views of the device according to another embodiment Fig 3 shows the right side view of the device of fig. 1 Fig 4 shows the left side view of the device of fig. 1 Fig 5 shows the right side view of the device of fig. 2 Fig 6 shows the left side view of the device of fig. 2 Referring to the drawings particularly figure 1, the cycle based device has a flywheel 1 mounted on a first shaft 2 and is adapted to receive the rotational drive from the rear rim 3 of a bicycle 4 through a belt 5 upon pedalling of the bicycle 4. The flywheel 1 is provided to create momentum during the operation of the device. The first shaft 2 is supported on the main frame 6 of the device by means of bearing assemblies 7 secured on either sides 8 of the of the frame 6. A big cycle rim 9 is mounted on the shaft 2 for transmitting the rotational movement to a small cycle rim 10 mounted on a second shaft 11 through a belt 12. The second shaft 11 is supported on the frame 6 by means of bearing assemblies 13 secured with the main frame 6. A big rim 14 is also mounted of the second shaft 11 for transmitting the rotational movement to the pulley 15 of the pump 16 through a belt 17 so as to lift the water. According to an option and as shown in figure 2 a pair of the big rims 18 is mounted on the first shaft 2 of the device such that to receive and transmit the rotational movement from the rear rim 3 of the cycle and to a small cycle rim 19 mounted on a third shaft 20 through the respective belts 21 and 22. The third shaft 20 is mounted on the top surface of the main frame 6. Flywheel 1 in this case is mounted on the third shaft 20. A big rim 23 is also mounted on the third shaft 20 at the end opposite to the flywheel end. The small rim 19 is mounted on the third shaft 20 between the flywheel 1 and the big rim 23. The second shaft 11 having a big rim 14 and a small rim 10 is mounted on the middle portion of the frame 6 such that to receive the rotational movement from the big rim 23 through its small rim 10 and transmit the same through its big rim 14, to the pulley 15 of the pump 16 provided to lift the water through a belt 24 & 25 respectively. By increasing the number of shafts and big and small rims the rpm of the device has been increased so as to lift the sufficient amount of water at the minimum input energy applied to operate the device. The main frame 6 of the device is preferably made of wood and comprises a pair of top horizontal plank 8 secured to another pair of middle and bottom horizontal planks 8 by means of connecting planks 8A provided in a vertical position and/or diagonal positions. In order to operate the device the respective belts from rear rim of the bicycle to the rim mounted on the first shaft and from the rim of the shaft to the second/third shaft are placed properly and the user starts pedalling the bicycle. Thus the rotational movement to the water lifting pump is transmitted through the rims mounted on the respective shafts, at the required rpm so as to lift the water and the liftina of the water takes olace.
