DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] Referring to FIGS. 1 and 2, a fuel distribution station 100 according to one embodiment of the present invention is shown. With specific reference to FIG. 1, the fuel distribution station 100 includes an upper canopy 101, a fuel distribution interface 130 suspended from the upper canopy 101, a fuel dispenser 170 in close association with the fuel distribution interface, a plurality of supporting structures 140 that support the upper canopy 101 in an elevated position above the ground so as to permit the passage of vehicles beneath the upper canopy 101, and a plurality of protective bumps/columns 150 for the protection of the supporting structures 140. The upper canopy 101 further includes a fuel tank dock 110 where one or more fuel tanks are located, and an equipment bay 120 in close association with the fuel tank dock 110 (e.g. beneath the fuel tank dock 110).

[0032] Turning to FIG. 2, the fuel tank dock 110 generally comprises an outer shell 1120, at least one fuel tank 1110 located within the outer shell 1120, and a fire shield wall 1140. The fuel tanks 1110 are in fluid communication with the fuel distribution interface 130 and the equipment bay 120 via fueling pipes 1130. The outer shell 1120 is preferably made of materials that are fireproof and ballistic-proof, such as those known in the art. The fire shield wall 1140 is disposed between the outer shell 1120 of the fuel tank dock 110 and the equipment bay 120, so as to isolate the fuel tanks 1110 and the equipment bay 12 from each other.

[0033] As will be readily appreciated, by having the fuel tanks 1110 located in the upper canopy 101 in an elevated position above the ground, the fuel distribution station of the present invention is more environmentally friendly by preventing the fuel tank 1110 and any potential leakage of fuel therefrom from contaminating the soil and underground water in the area surrounding the fuel distribution station, as compared to the conventional fuel stations whose fuel tanks are buried in the ground.

[0034] More importantly, it shall be noted that it is easier and cheaper to perform any maintenance work and/or repairs on the fuel tanks 1110 of the present invention compared to conventional fuel stations, as the fuel tanks 1110 of the present invention are located in the upper canopy 101 and are easily accessible, while the fuel tanks in the conventional fuel station are buried underground and a thick block of covering concrete has to be broken in order to gain access to the fuel tanks. In addition, the financial and labor cost for building the fuel distribution station 100 of the present invention is significantly lower than that for building a conventional fuel station, as building of the fuel distribution station 110 does not require significant excavation and underground work.

[0035] It should also be noted that electricity consumption by the mechanical pumping equipment in the present invention may be greatly reduced as compared to the conventional fuel station, as the present invention partially utilizes the weight of the fuel to distribute the fuel from the elevated fuel tanks 1110 to the fuel dispenser 170, while the conventional fuel station solely depends on the mechanical pump equipment for pumping the fuel from underground fuel tanks to the fuel dispenser. In particular, by locating the fuel tanks 1110 and the fuel dispenser 170 in the canopy, above vehicles to be refueled, fuel can be dispensed almost entirely or, indeed, entirely, using the force of gravity. This is in contrast to existing fuel stations which require pumps to pump the fuel from the underground tanks, upward to the dispenser, and to a vehicle to be refueled. Accordingly, significant reductions in the amount of electricity utilized can be realized.

[0036] As shown in FIG. 2, in one preferred embodiment of the present invention, the equipment bay 120 is located beneath the fuel tank dock 110 and is elevated to a position so as to permit the passage of vehicles beneath the equipment bay when the vehicles enter into the fuel distribution station for fueling. The equipment bay 120 comprises multiple compartments 1202, 1204, 1206, etc. to accommodate different equipment including pumps, filters, and fire suppression systems (e.g., hydraulic and mechanical equipment). This equipment located inside the equipment bay 120 is in fluid communication and electrical communication with the fuel tanks 1110 within the fuel tank dock 110, the fuel dispenser interface 130 and the fuel dispenser 170 suspended from the upper canopy 101.

[0037] It should be noted that, by locating the equipment bay 120 separately from and beneath the fuel tanks 1110, and by inserting the fire shield wall 1140 between the equipment bay 120 and the fuel tank dock 110, the present invention effectively prevents sparks from being generated accidentally by the hydraulic and mechanical equipment and inducing fire on the fuel tanks 1110, thereby enhancing the overall safety of the fuel distribution station. In addition, the fuel tank dock 110 is capable of providing shelter to the equipment bay 120 beneath it in different weather conditions.

[0038] Referring to FIG. 2, a fuel distribution interface 130 is connected to and suspended from the upper canopy 101 via at least one suspending holder 1310, so as to suspend the fuel distribution interface 130 in an elevated position and in a predetermined distance above the ground. The fuel distribution interface 130 further includes an electronic digital display 1312 to digitally display information to an operator and/user of the fuel distribution station, and an input panel 1314 for the operator and/or user to input information. A fuel dispenser 170 is also suspended from the upper canopy 101 and is disposed in close association with the fuel distribution interface 130.

[0039] In an embodiment, the height of the fuel distribution interface 130 is selectively adjustable so as to accommodate the height of the operator and/or user of the fuel distribution station 100, as well as to accommodate the height of the vehicles entering the fuel distribution station 100 for fueling. A sensor can be arranged in association with the fuel distribution station 100 (e.g., with each dispenser) to detect the height of the vehicles entering into the fuel distribution station and to transmit the height data of the vehicles to the fuel distribution interface 130. The fuel distribution interface 130 thereby is capable of adjusting its height automatically based on the height data of the vehicles entering into the fuel distribution station 100.

[0040] As disclosed above, the fuel distribution station 100 of the present invention provides a number of distinct advantages over the conventional fueling stations. First, suspending the equipment bay 120 and the fuel distribution interface 130 from the upper canopy 101 reduces the chance of a vehicle crashing into a component or components of the fuel distribution interface 130 as compared to a conventional fuel station where the pumping and fuel distribution unit/kiosks are mounted on the ground.

[0041] Moreover, by eliminating the pumping and fuel distribution units/kiosks from ground level, the fuel distribution station 100 of the present invention requires fewer protective bumps/columns and other barriers, as compared to conventional fuel stations in which each pumping and fuel distribution unit/kiosk requires a plurality of barriers for impact protection. Thus, the fuel station of the present invention requires less infrastructure, and is therefore less costly than known counterparts. Moreover, by eliminating ground based fueling kiosks, the present invention provides a more flexible traffic pattern within the footprint of the station. Therefore, a vehicle can enter the fuel distribution station 100 from various directions, and park in various angles and directions, as long as it can be reached by the fuel dispenser 170, and can exit the fuel distribution station in a number of different directions, whereas a vehicle entering a conventional fuel station from the ingress of a lane, can park only in parallel to the pumping and distribution unit for fueling purposes and exit via the lane where it parked.

[0042] Turning to FIG. 3, the fuel tanks 1110 includes at least one fuel tank. In one preferred embodiment as shown in FIG. 3, the fuel tank 1110 includes a plurality of fuel tank compartments 1112, 1114, 1116, 1118, etc. The fuel tank compartments can be of the same or various shapes and sizes and are connected to adjacent fuel tanks via fuel tank connectors 1004. Each fuel tank compartment can store one type of hydrocarbon-based fuel, and all fuel tank compartment can store the same type of hydrocarbon fuel or various types of hydrocarbon fuels, including but not limited to gasoline, diesel, CNG (compressed natural gas), LPG (liquefied petroleum gas), hydrogen and methanol.

[0043] It should be noted that all of the fuel tank compartments 1112, 1114, 1116, 1118 and the fuel tank connectors 1004 have a double wall structure which comprises an outer wall 1001, an inner wall 1002, and fire and ballistic resistant material 1003 such as pyrolite within the space in-between the outer wall 1001 and inner wall 1002. The double wall structure therefore is capable of preventing the fuels inside the fuel tanks from catching on fire for a minimum of two hours during a fire.

[0044] Importantly, in addition to the fuel tank compartments 1112, 1114, 1116, 1118, all other wall structures within the fuel distribution station 100, such as the wall structure of the supporting structures 140, the outer shell 1120 of the fuel tank dock 110, the suspending holder 1310, the equipment bay 120, etc. may comprise the aforementioned double wall structure. For example, the wall of the supporting structures 140, as shown in FIG. 3, may comprise an outer wall 1010, an inner wall 1011, and fire and ballistic resistant material 1012 such as pyrolite in-between the outer wall 1010 and inner wall 1011. Therefore, the adoption of the double wall structure enhances the overall fire and ballistic resistance of the fuel distribution station.

[0045] With further reference to FIG. 3, the fuel tank connectors 1004 connect the fuel tank compartments 1112, 1114, 1116, 1118, etc. to one another. Although the fuel tank connectors 1004 are partially integrated into the double wall structure of the fuel tank compartments, the outer wall of the fuel tank connectors 1004 does not reach the inner wall 1002 of the fuel tank compartments. The gaps between the outer wall 1005 of the fuel tank connectors 1004 and the inner wall 1002 of the fuel tank compartments provide the fuel tanks 1110 with the ability to release the pressure generated by the thermal expansion and contraction due to the temperature changes over the seasons.

[0046] Turning now to FIG. 4, the equipment bay 120 comprises an equipment supporting frame 1201 which may further divide the equipment bay 120 into more than one compartment such as compartments 1202, 1204, 1206, etc. Each compartment can be the same or different in terms of shape and size. The compartments may contain equipment including, but not limited to, pumps, filters, and fire suppression systems. It shall be noted that the equipment bay 120 can be modified to accommodate hydrocarbon cracking equipment, so as to refine any known liquid hydrocarbon fuel into LPG.

[0047] Although this invention has been shown and described with respect to the detailed embodiments thereof, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed in the above detailed description, but that the invention will include all embodiments falling within the scope of this disclosure.
