1. Field of invention

[0001]

Through this invention we propose a new and efficient way of generating electricity. Specifically the project uses a construction equipped with rollers that replaces the traditional speed breakers. The field of invention in general is power generation.

2. Prior arts

[0002]

Patent no. DE102008025488 by Weininger implements rocker mechanism for producing electricity. This device allows conversion of kinetic and potential energy of the traffic flow into electrical energy. For example the energy of vehicles by a valve arranged in or on a traffic plate system is received by a closed hydraulic system based on the energy of rocking plates into rotational energy of a turbine can be converted.

[0003]

Patent no. WO2013011519 by Totaram uses a platform plate which is kept inclined on a raised base level to allow vehicles to pass over the raised surface. In this construction system there are slide ratchet bars, shafts, balance wheels & springs. That is sure that system will not work till a vehicle passes on road way. Slide bars are attached with free wheel type gears. Slide bars go down from upper to lower position with the speed of the vehicle. As slide bars are attached with free wheel type gears, they transform the axle shaft into cyclical speed. And the axle shaft activates the revolving speed of the generator and the generator in turns works for electric generation.

[0004]

Patent no. EP2045596 by Smits comprises a frame, a surface section for supporting passing traffic which is moveable in a vertical direction between an upper rest position and a lower drive position under the influence of the weight of traffic passing by, the surface section being supported by counter pressure means for moving the surface section from the lower drive position to the upper rest position, a movement transformation member for conversion of the downwardly directed movement of the surface section into a rotational action of a driving axis of an electric generator, wherein the counter pressure means comprise at least one gas spring.

3. Summary of invention

[0005]

One drawback of the previous known arrangements is that the movements of the ramps and other road surfaces which make use of the downward and upward motion caused by the passing vehicles is non-uniform. Also the forces experienced by those systems have the risk of premature wear and tear. To change the springs, the road would have to be blocked and that would disrupt the flow of traffic. Also undesired shocks may be experienced by drivers and passengers of vehicles which pass over the mechanism.

[0006]

The present invention aims to minimize or eliminate the drawbacks of the existing models.
[0007]

The system according to the invention is designed be used in roads, highways and at the entrance of parking lots and any other place having a good rate of flow of traffic throughout the day for continuous production of electricity .

[0008]
The system according to the invention consists of rollers which are connected to a generator via chains and a gear mechanism that converts the kinetic energy of the vehicle into electrical energy.

4. Drawings and tabulated data

[0009]

Figure 1 shows the top view of the invention.

[0010]

Figure 2 shows the side view of the invention.

[0011]

Figure 3 shows the simulation conditions when the invention was tested in ANSYS Workbench®. It was assumed that a vehicle of mass 200kgs (with driver) passes over the invention. Since at a time only one of the tire is on the roller thus for a given instant the roller carries a weight of lOOkgs. Also some rotation is imparted to it, so to be on safer side it is rotated at 100 rad/s.

[0012]

Figure 4 shows the results of the simulation on the invention. The maximum stress on the bearings was 0.62MPa, which is well within the yield point for SS.

[0013]
Table 1 shows the results of the experiments conducted on the prototype invention. It is observed that on moving a small vehicle over the roller, the speed varies from 10-15 km/hour, the voltage produced is in the range of 3-4 volts.

5. Descriptions with reference to drawings and tabulated data

[0014]

The following discussion refers to the construction design of the invention. The system comprises of a base and two ramps (land 14 in figure 1), made of plywood to make the model portable. Two pieces of plywood (20 and 21 in figure 2) with dimensions 82x875 mm were cut which support the ramps. Two more side supports of dimensions 446x157 mm were cut which acts as bearing supports (22 in figure 2). Figure 1 shows the complete ramp and base assembly. Three MS shafts (2,3 and 4 in figure 1) lm in length, 28.5mm OD and 3mm thickness are fitted between the two side supports with the help of six journal bearings. On each shaft one MS Roller (11, 12 and 13 in figure 1) of 78mm OD and 2mm thickness was welded using MS plates of 2mm thickness. On each sides of shaft, 15 cm CI sprockets of 24 teeth were welded. Also two SS bearings were attached 7cm from each end. Fig shows the final assembly of the invention. The three MS rollers are connected to each other via chains inside the ramps. The outer parts of the end rollers have CI sprockets (5, 6, 7, 8 and 9 in figure 1) with 40 teeth welded on them. This is turn is connected to a smaller sprocket (15 in figure 2) with 18 teeth. That in turn is connected to the shaft of the generator. The rollers are joined by chains so as to provide a uniform movement in all the rollers.

[0015]

The invention converts the kinetic energy of the moving vehicles into electrical energy. As a vehicle passes over the rollers, it rotates it in the opposite direction of the wheel. The rollers are connected via chains so as to give them uniform rotation at all times. The end roller is connected via a chain to a smaller sprocket which is joined to the shaft of the generator.

[0016]

The system according to the invention completely eliminates the use of springs which get worn down due to rapid expansion and compression
