Description

Gas station piping installation structure and fueling system

[0001] Embodiments of the present invention relate to a gas station piping installation structure and a gas dispensing system.

[0002] As is well known, most existing gas stations are constructed by burying hazardous material pipes (e.g., fuel pipes, underfloor pipes, vent pipes, vapor recovery pipes, etc.) (hereinafter referred to as “pipes”) underground.

[0003] For this reason, the pipes of gas stations are buried underground, and after construction, they are structured in a way that makes it difficult to visually observe or inspect the buried pipes.

[0004] However, if a long period of time passes after the pipe is buried underground and constructed, serious damage to the pipe, such as twisting deformation or corrosion of the pipe, may occur depending on external conditions such as various external forces and the environment.

[0005] If a pipe is damaged, oil can leak out, contaminating the soil. This has necessitated costly remediation efforts to clean up the soil.

[0006] Thus, it's crucial to inspect gas station pipes for damage beforehand, and to ensure they don't miss the right time for replacement. However, the conventional method of burying gas station pipes underground makes it difficult to inspect the condition of buried pipes, making it easy to miss the right time for pipe replacement.

[0007] Therefore, in the gas station pipe installation structure, there is a need for structural improvement to enable easy pre-inspection of the pipe even after construction and to easily perform pipe replacement work without missing the pipe replacement period.

[0008] In particular, there is a need to develop a technology that centralizes the gas station pipes within a certain structure so that the pipes can be visually inspected for damage at any time without digging the ground, and pipe replacement work can be performed in a timely manner.

[0009] In addition, there is a need to develop a technology that can prevent soil contamination in advance by using a separate collection means to collect the leaked oil from the pipe in case of an accidental oil leak from the pipe.

[0010] As a prior art related to the present invention, there is Korean Patent Application No. 10-2014-0135811 (hereinafter, “prior art”), and the prior art discloses a technology related to a gas station pipe monitoring system.

[0011] However, the prior art document disclosed herein merely suggests a method for determining the presence of abnormalities in fuel supply pipes using sensors that detect pressure and temperature within the pipes, and reporting the presence of abnormalities to a central monitoring station. In other words, the prior art document does not provide any structure for centralizing pipes within the pit to enable visual inspection.

[0012] The purpose of the present invention is to provide a gas station pipe installation structure in which the pipe can be easily replaced without missing the pipe replacement period by making it easy to visually inspect the pipe through a cover even after the pipe has been constructed.

[0013] In addition, an object of the present invention is to provide a gas station pipe installation structure that can centrally arrange the pipes of a gas station so that they are exposed on the ground by forming a pit (i.e., a box-shaped concrete structure with an open top) equipped with a predetermined pipe installation conduit under the gas station installation surface where the gas station is installed.

[0014] In addition, an object of the present invention is to provide a gas station pipe installation structure that can prevent soil contamination due to oil spills in advance by allowing oil to be collected using a collecting device even when oil spills occur from the pipes.

[0015] In addition, the purpose of the present invention is to provide a gas station pipe installation structure that can reduce customer inconvenience caused by noise / vibration during operation of the gas pump and improve gas pump maintenance by arranging a gas pump flow unit including a motor, pump, and valve that operate to supply fuel to the gas pump body inside a pit formed underground.

[0016] In addition, the purpose of the present invention is to provide a fueling system that can reduce customer inconvenience due to noise / vibration and improve fueling system maintenance by positioning fueling-related components such as a fueling unit body, a fueling hose, and a fueling nozzle on the upper side of a fueling unit installation surface, and isolating and housing the fueling unit flow rate within a pit on the lower side of the fueling unit installation surface.

[0065] [Overall structure of the gas station piping installation structure]

[0066] A gas station pipe installation structure (1) according to one embodiment includes a pit (20), a pipe (40), a cover (50), and a fuel collecting device (70).

[0067] A pit (20) can be formed below a fuel pump installation surface (11) on which at least one fuel pump (10) is installed.

[0068] Here, the number and type of fuel dispensers (10) may vary depending on the gas station. For example, referring to Fig. 1, a structure with four fuel dispensers (10) installed is shown. However, the present invention is not limited to the illustrated form, and the number and type of fuel dispensers (10) may be changed without limitation.

[0069] The pit (20) is a concrete structure formed under the fuel pump installation surface (11) where at least one fuel pump (10) is installed, and the upper part (21) is open, and the remaining surfaces except for the open upper part (21), for example, the lower part and both sides, may have a box-shaped structure that is closed.

[0070] A square cross-section pipe installation conduit (30) may be formed inside the pit (20). A plurality of pipes used in a gas station may be installed so that they are exposed on the ground through the pipe installation conduit (30). In addition, the pipes installed through the pit (20) may be connected to an underground tank (3) (see FIG. 1).

[0071] A pipe (40) may be installed along the pipe installation conduit (30) within the pit (20). The pipe (40) that may be installed and used along the pipe installation conduit (30) within the pit (30) may be a hazardous material pipe of a gas station. For example, the hazardous material pipe may include a fueling pipe, a lowering pipe, a vent pipe, and a vapor recovery pipe, and may additionally include a number of other pipes as needed.

[0072] The cover (50) refers to a cover member that is openably and closably connected to the open upper portion (21) of the above-mentioned pit (20).

[0073] The cover (50) is connected to cover the open upper part (21) of the pit (20), and protects the pipe (40) installed in the pipe installation conduit (30) from the outside, but since it has a plurality of holes (52), the pipe (40) installed in the pipe installation conduit (30) can be exposed to the ground (11). Accordingly, even when the cover (50) is covered, the worker can visually inspect the pipe (40) at any time, and can easily check for damage and aging of the pipe (40). In addition, the cover (50) has a detachable structure, so that the cover (50) can be separated and the damaged or aging pipe (40) can be easily replaced.

[0074] In addition, the gas station pipe installation structure (1) according to one embodiment of the present invention further includes a fuel collecting device (70). The fuel collecting device (70) is configured to collect fuel flowing out from the pipe (40) into the interior of the pipe installation conduit (30).

[0075] Hereinafter, the detailed configuration of the pit (20), cover (50), and fuel collecting device (70) included in the gas station pipe installation structure (1) according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0076] [feet]

[0077] In a gas station pipe installation structure (1) according to one embodiment, a pit (20) is formed on the ground where the fuel dispenser (10) is installed, i.e., below the fuel dispenser installation surface (11).

[0078] As an example, the pit (20) may be a box-shaped concrete structure with an open top (21).

[0079] A cover (50) can be attached to the open upper part (21) of the pit (20).

[0080] Additionally, a square cross-section pipe installation conduit (30) may be formed inside the pit (20). Through the pipe installation conduit (30), a number of pipes used in a gas station may be installed so that they are exposed on the ground.

[0081] The number and type of fuel dispensers (10) can be varied. Referring to Fig. 1, four fuel dispensers (10) are shown installed on the ground, i.e., above the fuel dispenser installation surface (110). The present invention is not limited to the form illustrated in Fig. 1, and the number and type of fuel dispensers (10) can be varied and used without limitation.

[0082] As an example, the pit (20) includes an open upper portion (21), a base portion (22), and a side portion (23).

[0083] The upper part (21) of the pit (20) is opened so that the cover (50) can be covered and joined.

[0084] The base portion (22) is formed horizontally at a set depth in the open upper portion (21), and can form a sealed lower surface of the pipe installation conduit (30) in which the pipe (40) is installed. The base portion (22) can have a concrete material.

[0085] The side portion (23) is a side wall portion formed by extending from both sides of the base portion (22) to the fuel pump installation surface (11), i.e., ground level, and forms a sealed side wall surface of a pipe installation conduit (30) in which a pipe (40) is installed. The side portion (23) may be made of concrete.

[0086] As an example, the pit (20) further includes a pipe support (60).

[0087] The pipe support (60) is installed so as to stand upright on the inner floor of the pipe installation conduit (30) and serves to support the pipe (40) by raising it upwards from the base (22) by a certain height. Accordingly, various pipe damages and problems, such as contamination and corrosion, that may occur when the pipe (40) touches the base (22) can be prevented in advance.

[0088] For example, the pipe support (60) may have a support shape in which one end (i.e., the lower end) is fixed to the base part (22), and the other end (i.e., the upper end) protrudes from the base part (22) to a set height and stands up. The pipe support (60) can lift the pipe (40) from the base part (22) to a set height and support it horizontally. The other end (i.e., the upper end) of the pipe support (60) may further be equipped with a U-shaped fixing member capable of wrapping and fixing a circular pipe (40).

[0089] As an example, the pipe (40) may be any of various types of pipes that can be installed along a pipe installation conduit (30) in a pit (20) formed below the ground where the fuel dispenser (10) is installed. For example, the pipe (40) may include all hazardous material pipes of a gas station (e.g., fuel pipe, underfloor pipe, vent pipe, vapor recovery pipe, etc.), and such pipes (40) are installed in the pit (20) so that workers can easily inspect the condition of the pipes from above the ground.

[0090] Referring to Fig. 5, a structure can be confirmed in which a pit (20) is formed on the ground where the fuel pump (10) is installed, i.e., the lower portion of the fuel pump installation surface (11), and a cover (50) is installed on the open upper portion of the pit (20). The pipe (40) is supported horizontally at a certain height from the ground so as not to touch the ground by a pipe support (60) and can be connected to the underground tank (3).

[0091] [sleeve]

[0092] In a gas station pipe installation structure (1) according to one embodiment, the cover (50) refers to a cover member that is openably and closably connected to the open upper portion (21) of the pit (20).

[0093] As an example, the cover (50) can be combined to cover the open upper portion (21) of the pit (20), thereby protecting the pipe (40) installed in the pipe installation conduit (30) from the outside.

[0094] In addition, the cover (50) has a number of holes (52), thereby allowing the condition of the pipe (40) installed in the pipe installation conduit (30) to be easily inspected and confirmed with the naked eye from the ground (11).

[0095] In addition, the cover (50) is made of a detachable structure that can be covered and combined with the open upper part (21) of the pit (20) or lifted and separated, so that damaged and aged pipes (40) can be easily replaced.

[0096] As a preferred embodiment, the cover (50) includes a cover body (51) and a hole (52) (see FIG. 2).

[0097] The cover body (51) refers to a cover having a size corresponding to the open upper portion (21) of the pit (20). And a hole (52) is formed in the cover body (51).

[0098] Here, the hole (52) can be formed by penetrating the cover body (51) in the thickness direction.

[0099] The hole (52) allows the condition of the pipe (40) installed in the pipe installation conduit (30) to be checked visually at any time without separating the cover body (51) while the cover body (51) is connected to the upper portion (21) of the pit (20).

[0100] For example, the cover (50) can use a grating member.

[0101] In other words, the cover (50) has a size corresponding to the open upper portion (21) of the pit (20), and may use a grating member in which a plurality of holes (52) are formed in a slit or lattice structure. The grating member is a type of cover in which holes (52) in a slit or lattice structure are formed penetrating in the thickness direction. The grating member has a structure that physically blocks the open upper portion of the pit (20) to protect the pipe (40) from the outside, while allowing the pipe (40) installed in the pit (20) to be visually inspected through the holes (52). Accordingly, it protects the pipe (40) installed in the pit (20) with sufficient rigidity, while allowing the worker to check the condition of the pipe (40) at any time.

[0102] [Oil collection device]

[0103] In a gas station pipe installation structure (1) according to one embodiment, the oil collecting device (70) refers to a device that collects oil leaked from a pipe (40). The oil collecting device (70) is configured to collect the leaked oil in order to prevent soil contamination, etc., when oil leaks from a pipe (40) installed in a pipe installation conduit (30) in a pit (20).

[0104] As an example, the collecting device (70) includes a water collection unit (71), a water transfer line (72), and a water separation unit (73) (see FIGS. 4 and 6).

[0105] The water collection unit (71) can collect and store water that has drained through the cover (50) and collected inside the pit (20) or oil that has leaked from the pipe (40) inside the pit (20). The water transfer line (72) refers to a line that transfers the water collected in the water collection unit (71). In addition, the water separation unit (73) refers to an oil separation tank that receives the water using the water transfer line (72) and separates the water.

[0106] As a preferred embodiment, the water collection unit (71) may be connected to at least one end of the pit (20) so as to be connected to the pipe installation conduit (30) (see FIG. 6).

[0107] In addition, the water collection unit (71) is provided with a water collection space having a predetermined size to collect the water or oil, and the water collection space may be formed at a position lower than the base unit (22).

[0108] As a preferred embodiment, the upper height of the water collection unit (71) may be formed to be equal to or lower than the height of the base unit (22). Accordingly, the water collected inside the pit (20) may flow along the base unit (22) to the water collection unit (71) and be collected.

[0109] Meanwhile, as an example, the collection device (70) may include a pump (711), a controller (712), and a sensor (713).

[0110] The pump (711) is connected to the water transfer line (72) and allows the water collected in the water collection unit (71) to flow through the water transfer line (72) to the water separation unit (73). The controller (712) controls the operation of the pump (711). In addition, a sensor (713) can be installed in the water collection unit (71) and can detect the water level of the water collected in the water collection unit (71).

[0111] The controller (712) can control the operation of the pump (711) based on the water level information detected by the sensor (713).

[0112] In a preferred embodiment, a plurality of sensors (713) may be provided. The plurality of sensors (713) may be positioned at different heights within the water collection unit (71).

[0115] Meanwhile, the present invention can provide a fueling system using the gas station pipe installation structure described above.

[0116] [Fuel System]

[0117] FIG. 7 is a cross-sectional conceptual diagram briefly illustrating a fueling system using a gas station piping installation structure according to one embodiment of the present invention, and FIG. 8 is a block diagram briefly illustrating a fueling system according to one embodiment of the present invention.

[0118] A fueling system according to one embodiment includes a pit (20), a pipe (40), and a cover (50), and a fueling flow unit (200) having a structure separate from a fueling body (100) may be positioned inside the pit (20) (see FIGS. 7 and 8).

[0119] A fuel pump (10) (see Fig. 1) includes a fuel pump body (100) and a fuel pump flow unit that is connected to the fuel pump body (100) and allows fuel to flow to supply fuel during fueling. Fuel flowing from an underground tank (3) (see Fig. 1) to the fuel pump is introduced into the interior of the fuel pump body (100) by the fuel pump flow unit, and can be supplied to the outside through a fuel hose (110) and a fuel nozzle (120) by a user's operation.

[0120] In the fueling system according to the present invention, the fueling flow part (200) built into the fueling machine can be separated from the outside of the fueling machine body (100).

[0121] According to one embodiment, the fuel pump flow unit (200) is separated from the exterior of the fuel pump body (100) and can be accommodated inside a pit (20) underground rather than above ground.

[0122] According to a preferred embodiment, the fuel pump flow unit (200) is separated from the exterior of the fuel pump body (100) installed on the upper portion of the fuel pump installation surface (or ground) (11), and may include at least one motor and pump (210) and a valve (220) placed inside an underground pit (20) (see FIGS. 7 and 8).

[0123] If the fuel pump flow unit (200) is isolated inside the pit (20) and spatially separated vertically from the fuel pump body (100) installed on the ground, customer inconvenience caused by the fuel pump flow unit (200) causing loud noise / vibration during fueling operation can be reduced.

[0124] Furthermore, the fuel pump body (100) and the fuel pump flow portion (200) can have separate structures, so that maintenance of the fuel pump can be improved.

[0125] The pit (20) can be formed at the bottom of the fuel pump installation surface (11) on which at least one fuel pump (10), more specifically, the fuel pump body (100), is installed.

[0126] The pit (20) may be a concrete structure formed at the bottom of the fuel pump installation surface (11) where the fuel pump body (100) is installed.

[0127] According to one embodiment, the pit (20) may be a structure with an open upper portion (21), and may have a box-shaped structure in which the remaining surfaces, excluding the open upper portion (21), for example, the lower portion, i.e., the base portion (22), and both sides, i.e., the side portions (23), are closed.

[0128] A predetermined storage space is secured inside the pit (20), and this storage space can be used as a pipe (30) for piping installation (see Fig. 3). The pipe (40) (see Fig. 3) installed in the pit (20) can be connected to an underground tank (3) (see Fig. 1) in which oil is stored.

[0129] In addition, a fuel pump flow unit (200) including a motor and pump (210) and a valve (220) capable of withdrawing and supplying fuel stored in an underground tank (3) (see FIG. 1) to a fuel pump main body (100) can be accommodated in a predetermined receiving space secured inside the pit (20) (see FIG. 7 and FIG. 8).

[0130] The cover (50) can be operably connected to the open upper portion (21) of the pit (20). The cover (50) covers and connects to the open upper portion (21) of the pit (20) to protect the pipe (40) (see FIG. 3) and the fuel flow unit (200) (see FIGS. 7 and 8) that can be accommodated inside the pit (20) from the outside. In addition, a pipe support (60) for supporting the pipe, etc. may be further provided inside the pit (20).

[0131] According to one embodiment, the fuel pump body (100) may include at least one fuel hose (110) and fuel nozzle (120) that can externally supply fuel supplied by the fuel pump flow unit (200) to a user through the fuel pump body (100).

[0132] According to one embodiment, the fuel pump flow unit (200) may include at least one motor and pump (210) housed within the pit (20). The at least one motor and pump (210) are separated from the fuel pump body (100) by a predetermined distance and may be driven to supply fuel to the fuel pump body (100).

[0133] In addition, according to one embodiment, the fuel pump flow unit (200) may include at least one valve (220) accommodated inside the pit (20). The at least one valve (220) is separated from the fuel pump body (100) at a predetermined distance from each other, and may open and close to control the flow of fuel supplied to the fuel pump body (100) by the operation of the motor and pump (210).

[0134] In this way, when the fuel pump flow unit (200) is isolated and housed inside a pit (20) located underground, inconvenience caused by noise / vibration, etc. generated from the fuel pump flow unit (200) during fueling operation in the fuel pump main body (100) can be minimized. In addition, since the locations of the fuel pump main body (100) and the fuel pump flow unit (200) are spatially separated, there is an advantage in that fuel pump maintenance is improved.

[0135] As described above, according to the configuration and operation of the present invention, a pit, which is a box-shaped concrete structure formed under the installation surface of the fuel pump and open at the top, can be used to centrally arrange the pipes so that they are exposed to the ground. Unlike the existing method of burying the pipes underground, the pipes constructed within the pit are exposed through the ground, which has the advantage of allowing for constant visual inspection of the pipes after construction. As a result, inspection of the pipes is made easier, allowing pipe replacement work to be performed without missing the replacement period.

[0136] In addition, according to the configuration and operation of the present invention, the pipes of a gas station can be centrally arranged so that they are exposed on the ground using a pit-shaped pipe installation conduit, so that the construction work of the pipes is convenient, and the convenience of inspection and replacement of the pipes after construction can be improved.

[0137] In addition, according to the configuration and operation of the present invention, even if an oil leak occurs from a pipe, it can be quickly monitored by the user through an oil vapor detection sensor, and the leaked oil can be collected into an oil-water separation unit using a separate oil collection device, thereby preventing soil contamination due to the oil leak in advance.

[0138] In addition, according to the configuration and operation of the present invention, a fuel pump flow unit including a motor and a pump that operate to supply fuel to the fuel pump body is arranged inside the pit, thereby reducing customer inconvenience caused by noise / vibration during fuel pump operation and improving fuel pump maintenance.

[0139] In addition, according to the configuration and operation of the present invention, fueling-related components such as a fueling pump body, a fueling hose, and a fueling nozzle are positioned on the upper part of the fueling pump installation surface, and a fueling pump flow unit including a motor and a pump that supply fuel between an underground tank and the fueling pump body is isolated and housed under the fueling pump installation surface, i.e., in an underground pit, thereby reducing customer inconvenience due to noise / vibration and improving fueling pump maintenance.

[0140] Although the present invention has been described with reference to the drawings exemplified above, it is to be understood that the present invention is not limited to the embodiments and drawings disclosed herein, and that various modifications may be made by those skilled in the art within the scope of the technical idea of ​​the present invention. Furthermore, even if the operational effects according to the configuration of the present invention were not explicitly described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be acknowledged.
