This disclosure relates generally to a generator system utilizing the weight of recurrent static loads to generate power.
There is a growing need for clean and sustainable energy resources as problems associated with climate change and diminishing non-renewable resources increase. For example, such a need exists due to the current dependence on fossil fuels for power generation, which is causing their depletion and is known to negatively impact the ecosystem. Therefore, and due to the ever-changing demand for clean and sustainable energy, technologies for harvesting readily available, clean, and sustainable energy are needed. Solar power, wind turbines, and hydroelectricity now exist for energy production, but present their own individual problems, such as with the need to consume valuable real estate to build and operate (i.e., farmland or other real estate consumed for wind and solar farms, land that is consumed when a hydroelectric plant is built and the resulting flowage, and the like).
Recurrent static loads are found around us every day. Particularly surrounding industries related to shipping and storing goods, static loads may be found in locations not limited to warehouses, ports, and parking lots. Known in the art are devices which generate electricity from downward forces, however only a fraction of the load's movement is utilized for power generation. It would be beneficial to take advantage of loads that undergo recurrent loading and unloading to generate power.
Where recurrent static loads are found, known existing infrastructure may be present. For example, bridges and loading systems exist in locations where recurrent static loads such as automobiles or cargo are frequently found. It would be beneficial to take advantage of existing infrastructure and/or real estate of the existing infrastructure to build power generation systems. For instance, a bridge may be built with the generator system of the disclosure and be contained to the space where a bridge already exists, requiring no additional real estate which may be valuable and expensive. Additionally, where more expansive electricity is not available or may be limited, particularly in remote areas, local systems can be critical for providing necessary electricity.
Therefore, a need exists for an improved power generation system for generating electricity.
According to the disclosure, a generator system configured to support a load and create electrical power includes a plurality of folding supports, a gear rack assembly positioned at a midpoint of the system, and a generator assembly. The system includes an upper support movable in an upward and a downward direction and a lower support that is fixed and extends parallel to the upper support. The plurality of folding supports includes at least two corresponding pairs of scissor arms, an upper track and a lower track, and a plurality of wheels for connecting the at least two pairs of scissor arms to the upper track and the lower track. The gear rack assembly includes an upper gear rack and a lower gear rack, a gear engaging the upper gear rack and the lower gear rack, and a shaft positioned at a center of the gear for rotating in a one-directional manner with the gear. The generator assembly includes a dynamo, the shaft connected to the dynamo for converting the one-directional rotational movement of the shaft into electrical power. When the load is added to the upper support, a weight of the load lowers the upper support such that the scissor arms expand in a horizontal direction by the plurality of wheels sliding in the upper track and the lower track, and the plurality of wheels push the upper gear rack and the lower gear rack, rotating the gear and the shaft, such that the rotational movement of the shaft is transferred to the dynamo for electrical power generation.
Also according to the disclosure, a system configured to generate power from supporting a load includes a lower support that is stationary and an upper support movable in an upward and a downward direction. The generator system includes at least two folding supports, a first folding support and a second folding support positioned on opposite ends of the system between the upper support and the lower support. The generator system includes a gear rack assembly positioned at a midpoint of the system between the first folding support and the second folding support, the gear rack assembly including an upper gear rack connected to the first folding support, a lower gear rack connected to the second folding support, and a gear for engaging the upper gear rack and the lower gear rack. The generator system includes a generator assembly including a shaft rotatable with the gear, the shaft connected to a dynamo for converting rotational movement of the shaft to electrical power. When the load is added to the upper support, a weight of the load lowers the upper support such that the folding supports expand in a horizontal direction and push the upper gear rack and the lower gear rack, rotating the gear and the shaft, such that the rotational movement of the shaft is transferred to the dynamo for electrical power generation.
According to the disclosure, a method of generating power includes positioning a load on an upper support of a system, the upper support configured to move in a downward direction under weight of the load, compressing a plurality of folding supports, the plurality of folding supports positioned between the upper support and a lower support, pushing a pair of gear racks attached to the plurality of folding supports in a horizontal direction, rotating a gear engaged with the pair of gear racks, rotating a shaft engaged with the gear, the shaft connected to a dynamo, and converting rotational movement of the shaft into electrical power at the dynamo.
Referring now to the discussion that follows and the drawings, illustrative approaches to the disclosed systems and methods are described in detail. Although the drawings represent some possible approaches, the drawings are not necessarily to scale and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present disclosure. Further, the descriptions set forth herein are not intended to be exhaustive, otherwise limit, or restrict the claims to the precise forms and configurations shown in the drawings and disclosed in the following detailed description.
This disclosure relates generally to a power generation system that generates power utilizing the weight of recurrent static loads on a system. An exemplary generator system may include a system with an upper support and a lower support. The upper support is configured to receive a load and move in a downward direction under the weight of the load. The generator system includes a plurality of folding supports which compress with the downward movement of the upper support. The generator system includes a gear rack assembly attached to the folding supports. The gear rack assembly is configured to rotate a gear with the compression of the folding supports, such that the rotation of the gear is transmitted via a shaft to a dynamo, providing a sustainable source of power generation.
Referring to the figures,
Upper support 102 and lower support 104 are connected to each other by one or more folding supports 106 at each of a front section 200 and a rear section 300 of system 100. Folding supports 106 are configured to compress and expand upper support 102 and lower support 104. In one example, each folding support 106 includes a set of elongated scissor arms 108a, 108b, a pivotable hinge 110, and a plurality of wheels 116, however other arrangements for compressing and expanding the upper support 102 and lower support 104 may be used. Scissor arms 108a, 108b intersect at their midpoint via pivotable hinge 110. Pivotable hinge 110 facilitates scissor-like movement between scissor arms 108a, 108b as distance D between upper support 102 and lower support 104 increases or is reduced, compressing arms 108a, 108b when distance D is reduced, and expanding arms 108a, 108b when distance D is increased.
Upper support 102 and lower support 104 include an upper track 112 and a lower track 114. Upper track 112 extends along a bottom surface of upper support 102 and lower track 114 extends along a top surface of lower support 104, such that upper track 112 and lower track 114 face inwards toward each other. Scissor arms 108a, 108b are attached at their ends to upper track 112 and lower track 114 via plurality of wheels 116. For example, a first scissor arm 108a is attached to upper track 112 at a first end via a first wheel 116a. A second scissor arm 108b is attached to lower track 114 at a first end via a third wheel 116c. System 100 may include one folding support 106 in each section 200, 300 of system 100 as illustrated in
At terminal ends 120 of upper support 102 and lower support 104, scissor arms 108a, 108b are connected to upper support 102 and lower support 104 via fixed hinges 118a, 118b. For example, first scissor arm 108a is attached at a first end to upper support 102 at wheel 116a and at a second end to terminal end 120 of lower support 104 at a first fixed hinge 118a. Second scissor arm 108b is attached at a first end to lower support 104 at wheel 116b and at a second end to terminal end 120 of upper support 102 at a second fixed hinge 118b. In embodiments with more than one pair of scissor arms 108a, 108b per section 200, 300, scissors arms 108a, 108b immediately adjacent to terminal ends 120 include fixed hinge 118a, 118b, while additional scissor arms may include four wheels as illustrated in
System 100 includes the above features at opposite ends of upper support 102 and lower support 104, creating front section 200 and rear section 300.
As illustrated in
Upper gear rack 402 includes an upper pulley 420 positioned on a top surface of upper gear rack 402. Lower gear rack 404 includes a lower pulley 422 positioned on a bottom surface of lower gear rack 404. Upper pulley 420 and lower pulley 422 are connected to gear 406 via a belt 426. Belt 426 ensures upper gear rack 402 and lower gear rack 404 remain positioned relative to gear 406. A shaft 414 is illustrated whose operation is further described in

At 710, load L is positioned on upper support 102 of system 100. At 720, its weight causes upper support 102 to begin to move in a downward direction. At 730, downward movement of upper support 102 causes folding supports 106 to compress. Compression of folding supports 106 includes scissor arms 108a, 108b pivoting about pivotable hinge 110 to compress to distance D2 between upper support 102 and lower support 104. Wheels 116 slide in upper track 112 and lower track 114 to extend to horizontal distance H2 between adjacent wheels 116. At 740, as wheels 116 slide along tracks 112, 114, wheels 116C attached to gear rack assembly 400 cause upper gear 402 and lower gear rack 404 to move. Wheels 116C slide in a direction towards the midpoint of system 100. Wheel 116C of front section 200 pushes upper gear rack 402 toward rear end 300. Wheel 116C of rear section 300 pushes lower gear 404 toward front section 200. Upper gear rack 402 and lower gear rack 404 substantially overlap, reducing the distance between folding supports 106 of front section 200 and folding supports 106 of rear section. At 750, as upper gear rack 402 and lower gear rack 404 move horizontally, gear 406 is rotated in a clockwise direction due to engagement of gear teeth 412 with upper rack teeth 408 and lower rack teeth 410. At 760, rotation of gear 406 in clockwise direction causes shaft 414 to rotate in a clockwise direction. At 770, shaft 414 extends into dynamo 418 as a receiving axle for dynamo 418, inputting rotational movement into dynamo 418 and converting mechanical rotation into a pulsing direct electrical current that can be utilized for power generation. Shaft 414 may include an automatic transmission box 416 which may aid in transferring rotational movement of shaft 414 into electrical power.
At 810, load L is removed from upper support 102 of system 100. At 820, upper support 102 moves in an upward direction to default position 600. Lifting of upper support 102 may be accomplished by means of springs, a motor that uses a portion of the energy generated by the shaft or mechanically using the weight of load L as it is removed from system 100. At 830, upward movement of upper support 102 causes folding supports 106 to expand. Expansion of folding supports 106 includes scissor arms 108a, 108b pivoting about pivotable hinge 110 to expand to distance D1 between upper support 102 and lower support 104. Wheels 116 slide in upper track 112 and lower track 114 to reduce horizontal distance H2 between adjacent wheels 116. At 840, as wheels 116 slide along tracks 112, 114, wheels 116C attached to gear rack assembly 400 cause upper gear rack 402 and lower gear rack 404 to move. Wheels 116C slide in a direction toward the respective terminal ends 120 of front section 200 and rear section 300. Wheel 116C of front section 200 pulls upper gear rack 402 toward terminal end 120 of front section 200. Wheel 116C of rear section 300 pulls lower gear rack 404 toward terminal end 120 of rear section 300. At 850, as upper gear rack 402 and lower gear rack 404 move, gear 406 is rotated in a counterclockwise direction due to engagement of gear teeth 412 with upper rack teeth 408 and lower rack teeth 410. As gear 406 rotates in counterclockwise direction, shaft 414 does not rotate with gear 406.
The present disclosure relates to a generator system 100 utilizing the weight of loads L that are present in a certain area for a certain period of time on a recurrent basis. That is, loads that undergo recurrent loading and unloading. Examples of such loads include, but are not limited to, vehicles in parking, ports, airports, etc., cargo/merchandise on top of ships, trucks, trains, etc., luggage/cargo/merchandise in stores, airports, ports, etc., people seated in theatres, polyvalent rooms, stadiums, waiting areas etc. or in vehicles, bicycles, chairs etc. and water in rivers or accumulated rainwater. The term load in this context includes, but is not limited to, vehicular and non-vehicular loads, where vehicular loads include land, air and water vehicles such as bicycles, automobiles, trucks, trains, ships, helicopters and airplanes. Non-vehicular loads include but are not limited to cargo, merchandise, luggage, animals, people and water.
The present disclosure relates to a generator system 100 which may be used in spaces with existing infrastructure, limiting the need for additional and expensive real estate for power generation. For example, where a bridge may exist and receives recurrent static loads of vehicles, the disclosed power generation system may be built into existing bridge with the same footprint of existing bridge such that additional real estate is not needed. Below description refers to examples of system 100 in existing locations and infrastructure for power generation.

Therefore, according to the disclosure, when load L is added to upper support 102, weight of L lowers upper support 102 such that scissor arms 108 expand in horizontal direction by wheels 116 sliding in tracks 112, 114. As wheels 116 slide in tracks 112, 114, upper gear rack 402 and lower gear rack 404 are pushed towards a midpoint of system 100, rotating gear 412 and shaft 414 such that rotational movement from shaft is transferred to dynamo 418 for power generation.
