Background technology
Along with the development of automobile with popularize, the petrol filling station highlights day by day in the importance of modern society.Because the petrol filling station stores and sells inflammable and explosive dangerous material, so have clear and definite requirement and standard to follow about petrol filling station's construction.But from the design of existing petrol filling station, though can both satisfy these requirements and standard greatly, exist many needs improve with can improved place.I am when a night refueling, this petrol filling station that goes has 24 nozzles of 6 fuel chargers (respectively there are two nozzles fuel charger both sides), 6 cars just altogether, not only can not refuel simultaneously (having two fuel chargers specially to add diesel oil), and chassis is arranged because first mistake stops attempting to inject correct station then and scurry here and there and waited for for a long time to the station that adds diesel oil in the station, so all do not add oil up to other car and leave away just to add and oil because other vehicle does not allow it jump the queue, the device resource of petrol filling station can not get sufficient utilization, the vehicle stand-by period increases and causes the increase of race of engine time and wastes energy.(this situation often occurs at home when petrol filling station's vehicle much occurs lining up situation, as before heightening oil price, festivals or holidays and contiguous during particularly wait during spring transportation), situations such as the phase mutual interference between the vehicle, device resource are not fully utilized are more serious, and the efficient of refueling when needs improve oiling efficient is lower on the contrary.
Cause the not high main cause of this oiling efficient to be that petrol filling station's layout is unreasonable.Owing to refuel station with sail track (same group of general track of refueling station gone in fingering) into and do not separate the track exterior domain that setting is provided in a side of among the track or also comprises close fuel charger, though can more lean on fuel charger some during actual the oiling or away from fuel charger a bit, be basic the coincidence in a word, but the vehicle that refuels refuels by joining before and after the direction of track substantially, and the position that takies like this is the longest.The one-sided fuel charger that two nozzles are arranged, can be that two chassis refuel in theory simultaneously, but because the position very long (kart is generally 4-5m) that the separate unit car takies, the petroleum pipeline length that connects nozzle is not enough, or two the fuel charger spacings in front and back fall short of, the general while can only be that a chassis refuels, and another nozzle is just left unused.Two fuel chargers in the front and back of a track homonymy, can be different group refuelings independently simultaneously in theory, but during using, reality falls short of owing to two the fuel charger spacing distances in front and back, if the foreground fuel charger has added oily vehicle and has sailed out of and soar but the backstage fuel charger refuels vehicle does not sail out of namely and also do not soar, the vehicle that oiling is waited in the back may be subjected to hindering the oiling that can't move ahead on the one hand, simultaneously may see not that also the foreground fuel charger soars and the oiling that do not move ahead, the foreground fuel charger is just left unused before these problems are eliminated like this; Also have at the vehicle that waits oiling mixed in together and when pasting very closely with the vehicle that is refueling, the obstruction of vehicle and can not sailing out of before and after the vehicle that adds oil is subject to, back vehicle also just can't in time be refueled; And in front and back when two fuel chargers refuel for different vehicle simultaneously, the vehicle that oiling is waited in the back that has is directly offside to wait oiling after refueling vehicle to the foreground, desires to sail out of then may be subjected to the obstruction of this car and can't sail out of if the backstage adds oily vehicle earlier.A kind of city, state, provincial highway (six-lane) petrol filling station layout plan have been announced in the Sinopec petrol filling station construction standard, three oiling island oblique parallels are arranged, straight-through track with respect to entrance and exit is oblique, but owing to refuel island and sail track (i.e. the alleged six-lane of this arrangement diagram title) accordingly into and overlaps, still can there be the situation of above-mentioned phase mutual interference in same track front and back oiling vehicle; And this design scheme has only one group to refuel island (three refuel islands constitute a group), at be a kind of place condition of limited, if there are two groups or more, six-lane is with regard to bad layout.
The interior traffic guiding in station is ineffective in addition, fuel charger also is important influence factor for the limitation of remote oiling.Although at present the entrance, petrol filling station has our station can add obviously promptings such as added oil product on oil product and each fuel charger, but work as petrol filling station's fuel charger quantity more for a long time, the driver will find suitable oiling station still may make mistakes, add the situation of reason temporary variations such as fuel charger fault or maintenance, vehicle enters the situation that is not suitable for station and happens occasionally, if will correcting to enter again, this situation of appearance can add the station that is fit to oil product, when the petrol filling station is very idle, be unchallenged, but in case be not even that very empty vehicle seldom also will be wasted many times and could realize, the example of front personal experience is exactly clear proof, more at vehicle, can be described as when the petrol filling station is busier to take a lot of trouble just does and obtains, because other vehicle generally can not allow it jump the queue.Because of indicate not clear or untimely cause to fight for refuel station and also may cause the mutual interference of vehicle phase, when last fuel charger soars in a track, in general adjacent lane sees more clearly than with the track, the adjacent lane vehicle is thought with losing sight of of track and is moved ahead earlier, also moves ahead after this track vehicle is found subsequently and cause and fight for like this, so at least wherein having a car can can't be moored to station refuels, thereby cause interference, therefore traffic guiding is also influential for oiling efficient in the station.Existing fuel charger refuels apart from very limited, refuel generally can only for hithermost station, because oil tank of vehicle has also having on the right of on the left side at present, if the fuel tank of oiling vehicle is not in close fuel charger one side, this vehicle must be moored to appropriate position and could refuel so in this case, because the petroleum pipeline of fuel charger falls short of, hindered in case be moored to appropriate position, so just can't refuel and make fuel charger before hinder eliminating, have to leave unused; An one-sided fuel charger that two nozzles are arranged is also mentioned because petroleum pipeline falls short of in the front has one to go up nozzle and left unused, and one-sided three nozzles and above fuel charger are arranged also is like this.
Summary of the invention
The present invention will solve the not high problem of existing petrol filling station's oiling efficient.For addressing the above problem, the object of the present invention is to provide a kind of petrol filling station design scheme, under the prerequisite of following relevant Compulsory Feature and standard, improve petrol filling station's layout, reduce the phase mutual interference of refueling between the vehicle, the utilization rate that improves fuel charger.Simultaneously, traffic guiding improvement project and fuel charger and related facility improvement project further improve the operating efficiency of petrol filling station in also can implementing on this basis to stand.The present invention also provides such scheme also can expand application at the refueling station of all types, and provides according to fuel charger and related facility improvement project and expanded to use and create filing provisions such as fuel charger, filling machine each is a kind of.
A kind of petrol filling station of the present invention design scheme reduces the oiling vehicle by improvement petrol filling station layout and disturbs mutually, thereby improves the utilization rate of fuel charger, and concrete scheme is:
The station that will refuel marks with obvious visible form with the station inside lane, as traffic lane line and the station profile that refuels of drawing on ground with coating, and the station that refuels separates fully with the station inside lane, there is not any coincidence, refuel simultaneously the island with refuel station oblique parallel setting (oblique referring to sail the track direction into not parallel, out of plumb, referring to Fig. 1) and its direction with sail into the folded acute angle of track direction greater than 15 the degree and less than 90 the degree, perhaps refuel the island with refuel station and laterally be set up in parallel and (laterally refer to sail the track direction into vertical or close to vertical, but the station of close entrance can directly be sailed into to need not to indicate and sail the track into by entrance, referring to Fig. 2) and the acute angle vertical or folded with sailing the track direction into more than or equal to 75 degree, this like this oiling station is just as the angle-park berth or the double parking berth can interference-freely be sailed into and rolled away from the same way, thereby reduces the phase mutual interference of refueling between the vehicle.Owing to occupation of land shape, the present position of petrol filling station in the reality, provide oil product kind and ratio to have multiple different situations, therefore above layout can be refueled regional or all refuel the zone in petrol filling station's part and be used according to actual conditions.Above scheme is bigger for the adjustment of existing petrol filling station layout, improvement cost is higher, therefore being necessary to use for reference such scheme thought realizes a kind of little to existing layout adjustment, a kind of scheme that improvement cost is lower, do not change existing oiling island layout, according to place situation adjustment member or all refuel station and relevant track (mainly being to sail the track into), specific practice is: the station that will refuel marks with obvious visible form with relevant track, but the station that refuels partially overlaps with sailing the track into and not exclusively separate but allow, refuel station oblique parallel setting (oblique referring to sail the track direction into not parallel, out of plumb, referring to Fig. 3) and with sailing the track direction into folded acute angle greater than 15 degree and less than 45 degree, so just can the phase mutual interference between the adjacent vehicle when rolling away from as the angle-park berth, and when sailing into if in order from not occurring disturbing as far as sailing into closely successively to refuel station or sail any unobstructed oiling station in the place ahead into yet, but the oiling station of crossing the existing vehicle parking in the place ahead then must move ahead outside the track and pour the oiling station again into until the preceding appropriate location of oiling station, also might roll away to crossing station parked vehicle simultaneously and cause certain interference.
Traffic guiding improvement project in a kind of station that can be used for above-mentioned petrol filling station design scheme, by implementing the relevant measure that improves traffic guiding in the station, disturbed condition appearance mutually between lay-by, the wrong vehicle that refuels station and cause of choosing is walked in minimizing, thereby improve oiling efficient, following measure is specifically arranged, these measures independent and integrated use as required:
A. set up and indicate our station and all refuel station orientation and can add the direction board of oil product gas kind, existing petrol filling station does not all have this direction board, only there is our station can add obviously promptings such as added oil product on oil product and each fuel charger in the entrance, petrol filling station, thereby unavoidably have some vehicles and sail unsuitable oiling station into, not only influence own oiling and also may influence other people, had this notice board just can reduce the generation of this error; Obviously can set up the direction board of subregion respectively under the situation of subregion and the subregion situation is obviously indicated all refueling stations, this situation is built the station jointly in some oiling aeratings, the irregular petrol filling station of overall shape may occur, and prompting can make vehicle avoid detours like this;
B. stand set up before inside lane sails into indicate this track enterable all refuel stations and can not refuel product kind notice board, the oil product of petrol filling station's sale generally has a variety of, and all oiling stations of a track homonymy can't provide the oil product of our station all kinds probably, remind the driver to wait in line in suitable track to refuel with regard to being necessary like this, particularly to remind the driver which oil product of track can not add, not misarrangement team; This notice board also only prompting can refuel the product kind, also have similar effect; Also can not only point out and to refuel product kind but also point out and to refuel the product kind, thereby make prompting more perfect;
C. wait the oiling zone in the entrance to refueling to set up between the station district, vehicle is not answered the right here waiting oiling and is provided obvious prompting when having the free time to refuel station, when being arranged, can sail into from the vehicle that this station refuels by the prompting of electronics board or by artificial guiding idle station, avoid refueling vehicle and refuel the mixing and the phase mutual interference of vehicle with waiting by this fueling area of waiting, refuel efficient thereby improve; If same formation waiting vehicle more than one and the preceding vehicle can not refuel from this station and then point out it to allow the back sail into or to allow other formation sail into earlier from the vehicle that this station refuels earlier from the vehicle that this station refuels; The judgement of idle station has dual mode, and a kind of is that vehicle sails out of, and hangs arms for second kind, though vehicle does not also sail out of the back vehicle and sails into and want certain hour yet when hanging arms, generally can offset with the time of departure, and efficient is higher like this;
D. limit traveling lane in the station of vehicle that the vehicle commander surpasses 7.5 meters, namely limit the lanes that vehicle that the vehicle commander surpasses 7.5 meters can only appointment in standing and provide obvious prompting; This class vehicle occupied ground generally surpasses kart 50%, so it takies, and the track is many, turning radius is bigger, refueling station also should be bigger, do not consider especially and will and then cause interference for other vehicle to self, consider then can reduce this situation generation especially by limiting the track, generally can limit the track that it can only walk outermost, can make the adverse effect of this class vehicle reduce to minimum like this, thereby improve oiling efficient; Also can also limit the oiling station simultaneously, further reduce the adverse effect of this class vehicle, influence to reduce as the zone that station is limited to as far as possible outside.
A kind of fuel charger and related facility improvement project that can be used for above-mentioned petrol filling station design scheme, common fuel charger in usefulness also can't be the group refueling of one at interval or above station now, even prolonging petroleum pipeline makes and can farther distance refuel, petroleum pipeline may bring influence to other vehicle pass-through so, expand the oiling distance of fuel charger and do not produce interference by improving fuel charger and related facility transformation, improve the service ability of fuel charger, thereby improve oiling efficient, its scheme at first is to prolong the petroleum pipeline that fuel charger connects nozzle, the station of oiling farthest that petroleum pipeline length is served is on demand determined, need farthest to serve to be separated by one and prolong 2.5-3 rice when refueling second station of station (at kart, approximate the width of a kart oiling station greatly), need farthest to serve to be separated by two and prolong 5-6 rice (approximate greatly two kart refuel the width of stations) when refueling the 3rd station of station, by that analogy, petroleum pipeline hung on the skyborne basis in front prolonging about the twice of suspension height again, is the 3 meters high 5-6 of prolongation again rice as suspension height; Then petroleum pipeline and related facility have been carried out one of following transformation:
A. suspension arrangement is set up in the fuel charger top, and petroleum pipeline is suspended in the air, and the petroleum pipeline of close nozzle from top to bottom during oiling; Cross bar or other can be above fuel charger, set up and the rail set of the suspension member (following general designation suspension member) of hook or the similar petroleum pipeline that can hang can be placed, each need be used for hanging at least 2 of the suspension members of petroleum pipeline for the nozzle of non-adjacent oiling station service, one of them directly over and adjacent domain fix, other is movable suspension member, can move around at rail set; Set up some screens annexes on the rail set, can temporarily fix to prevent that when refueling petroleum pipeline from swinging significantly when suspension member is limited by the screens annex, firmly pulling can be broken away from the restriction of screens annex and realize that suspension member moves around;
B. arranging on ground can be for the groove of petroleum pipeline by also playing a protective role, dig a groove on ground, its degree of depth can be placed petroleum pipeline and is not exposed on the ground, width is slightly larger than the petroleum pipeline diameter, the 5.5cm degree of depth can be made as the petroleum pipeline recess width for diameter 4cm and 6.5cm can be made as, because the limited 8cm that generally is no more than of width, and groove itself has certain intensity, vehicle by the time can not be pressed onto petroleum pipeline, petroleum pipeline passes through from groove when refueling for non-adjacent oiling station, establish some adjustable clamps on the groove, preventing that petroleum pipeline from pulling out from groove, during oiling near the petroleum pipeline of nozzle from bottom to top;
C. petroleum pipeline outsourcing one deck can prevent from flattening damage by pressure and do not influence pipe bending the hard topping, connect short steel pipe and connect with soft material as the hard topping that becomes tubulose to make with steel band or reinforcing bar helical buckling, with soft material and be difficult for breaking and the very short hard topping of making much smaller than short steel pipes length of length etc., damaged by pressure by vehicle preventing, also be convenient to simultaneously stretch and shrink, petroleum pipeline subsides ground is passed through when refueling for non-adjacent oiling station, generally should paste ground from oiling station vehicle tail end and pass through;
D. arranging on ground can be for the groove of petroleum pipeline by also playing a protective role, identical among groove design and the b., petroleum pipeline outsourcing one deck can prevent from flattening damage by pressure and do not influence pipe bending hard topping (design with c. in similar), damaged by pressure by vehicle preventing, also be convenient to simultaneously stretch and shrink, petroleum pipeline passes through from groove when refueling for non-adjacent oiling station;
E. laying on the ground can be for the groove facility of petroleum pipeline by also playing a protective role; the groove facilities design is similar to the b. further groove; but one independently can installing/dismounting device; need not dig ground; and can bear the pressure of oiling vehicle, petroleum pipeline passes through from the groove facility when refueling for non-adjacent oiling station.
A kind of fuel charger by above-mentioned fuel charger and the manufacturing of related facility improvement project, concrete scheme: the petroleum pipeline that has prolonged fuel charger connection nozzle, the station of oiling farthest that petroleum pipeline length is served is on demand determined, prolong 2.5-3 rice (at kart if serving is separated by one farthest when refueling second station of station, approximate the width of a kart oiling station greatly), need farthest to serve to be separated by two and prolong 5-6 rice (approximate greatly two kart refuel the width of stations) when refueling the 3rd station of station, by that analogy, petroleum pipeline hung on the skyborne basis in front prolonging about the twice of suspension height again, is the 3 meters high 5-6 of prolongation again rice as suspension height; But while petroleum pipeline also outsourcing one deck can prevent from flattening the hard topping that damages by pressure and do not influence pipe bending; connect short steel pipe and connect with soft material as the hard topping that becomes tubulose to make with steel band or reinforcing bar helical buckling, with soft material and be difficult for breaking and the very short hard topping of making much smaller than short steel pipes length of length etc., damaged by pressure by vehicle to prevent petroleum pipeline.
The traffic guiding improvement project also can be used for lpg service station in above-mentioned petrol filling station design scheme and the available station, the refueling station of other types such as station is built in compressed natural gas gas station or the aerating of refueling jointly, the similar processing of oiling is pressed in aerating, unify to consider to get final product, lpg service station, the compressed natural gas gas station, the aerating of refueling is built the station jointly and is waited other refueling station and petrol filling station to be referred to as refueling station, all types refueling station requirements on Construction is consistent with standard substantially, though aerating and oiling have very big difference aspect key facility, but the vehicle for the oiling aerating, its oiling aerating form is similar substantially, therefore can unify to consider.Like this, the traffic guiding improvement project just can be used for petrol filling station, lpg service station, compressed natural gas gas station or the aerating of refueling and builds the reconstruction of all types refueling stations such as station and/or petrol filling station, lpg service station, compressed natural gas gas station or the aerating of refueling jointly and build the newly-built of all types refueling station such as station jointly in above-mentioned petrol filling station's design scheme and the available station.
Above-mentioned petrol filling station design scheme can with fuel charger and related facility improvement project can be used under the normal temperature that stores under low temperature such as other liquid, colloidal substance, Powdered solid matter or liquefied petroleum gas, compressed natural gas or the condition of high voltage or the atmospheric pressure state being the filing provision of the material of gaseous state and the improvement of related facility, press the similar processing of petroleum pipeline connecting filling head device delivery pipe, related facility is also by the similar processing of corresponding facility, thereby the distance of expansion filling promotes the service ability of filing provision.With lpg service station, filling machine and related facility that the station is built in compressed natural gas gas station or the aerating of refueling jointly are example, can at first prolong filling machine connects carrier pipe as the air filling gun of filling head device (the filling machine equipment that has has two similar filling head devices, handle by same way as, the back illustrates no longer separately), the station of aerating farthest that delivery tube is served is on demand determined, need farthest to serve to be separated by one and prolong 2.5-3 rice when refueling second station of station (at kart, approximate the width of a kart oiling station greatly), need farthest to serve to be separated by two and prolong 5-6 rice (approximate greatly two kart refuel the width of stations) when refueling the 3rd station of station, by that analogy, petroleum pipeline hung on the skyborne basis in front prolonging about the twice of suspension height again, is the 3 meters high 5-6 of prolongation again rice as suspension height; Then carrier pipe and related facility have been carried out one of following transformation:
A. suspension arrangement is set up in the filling machine top, and carrier pipe is suspended in the air, and the carrier pipe of close air filling gun from top to bottom during aerating; Cross bar or other can be above filling machine, set up and the rail set of the suspension member (following general designation suspension member) of hook or the similar carrier pipe that can hang can be placed, each need be used for hanging at least 2 of the suspension members of carrier pipe for the air filling gun of non-adjacent aerating station service, one of them directly over and adjacent domain fix, other is movable suspension member, can move around at rail set; Set up some screens annexes on the rail set, can temporarily fix to prevent that when refueling carrier pipe from swinging significantly when suspension member is limited by the screens annex, firmly pulling can be broken away from the restriction of screens annex and realize that suspension member moves around;
B. arranging on ground can be for the groove of carrier pipe by also playing a protective role, dig a groove on ground, its degree of depth can be placed carrier pipe and is not exposed on the ground, width is slightly larger than internal diameter of delivery hose, can be the 5.5cm degree of depth as the carrier pipe width for diameter 4cm and can be 6.5cm, because the limited 8cm that generally is no more than of width, and groove itself has certain intensity, vehicle by the time can not be pressed onto carrier pipe, carrier pipe passes through from groove when refueling for non-adjacent aerating station, establish some adjustable clamps on the groove, preventing that carrier pipe from pulling out from groove, during oiling near the carrier pipe of air filling gun from bottom to top;
C. carrier pipe outsourcing one deck can prevent from flattening and damage by pressure and do not influence crooked hard topping, connect short steel pipe and connect with soft material as the hard topping that becomes tubulose to make with steel band or reinforcing bar helical buckling, with soft material and be difficult for breaking and the very short hard topping of making much smaller than short steel pipes length of length etc., damaged by pressure by vehicle preventing, also be convenient to simultaneously stretch and shrink, carrier pipe subsides ground is passed through when refueling for non-adjacent aerating station, generally should paste ground from aerating station vehicle tail end and pass through;
D. arranging on ground can be for the groove of carrier pipe by also playing a protective role, identical among groove design and the b., carrier pipe outsourcing one deck can prevent from flattening damage by pressure and do not influence pipe bending hard topping (design with c. in similar), damaged by pressure by vehicle preventing, also be convenient to simultaneously stretch and shrink, carrier pipe passes through from groove when refueling for non-adjacent aerating station;
E. laying on the ground can be for the groove facility of carrier pipe by also playing a protective role; the groove facilities design is similar to the b. further groove; but one independently can installing/dismounting device, need not dig ground, carrier pipe passes through from the groove facility when refueling for non-adjacent aerating station.
Press above-mentioned fuel charger and related facility improvement project at lpg service station, a kind of filling machine of the expansion application scheme manufacturing at station is built in compressed natural gas gas station or the aerating of refueling jointly, concrete scheme is: prolonged the carrier pipe of filling machine connection as the air filling gun of filling head device, the station of aerating farthest that delivery tube is served is on demand determined, prolong 2.5-3 rice (at kart) if will serve second station of the aerating station of being separated by, prolong 5-6 rice if will serve the 3rd station of two the aerating stations of being separated by, by that analogy, carrier pipe hung on the skyborne basis in front prolonging about the twice of suspension height again, is the 3 meters high 5-6 of prolongation again rice as suspension height; Or simultaneously carrier pipe also outsourcing one deck can prevent from flattening the hard topping that damages by pressure and do not influence pipe bending; as bending to hard topping that tubulose makes with ribbon spiral, connecting short steel pipe and connect with soft material with soft material and be difficult for breaking and the very short hard topping of making much smaller than short steel pipes length of length etc., damaged by pressure by vehicle to prevent carrier pipe.
With respect to existing petrol filling station, through petrol filling station provided by the invention design scheme, can reduce the phase mutual interference of refueling between the vehicle, improve oiling efficient, after the efficient of refueling improves, the oiling vehicle stand-by period reduces, and the also corresponding minimizing of waste gas that the race of engine causes energy waste also to reduce, discharge is so also have the effect of environmental protection and energy saving simultaneously.In the such scheme in the available station traffic guiding improvement project and and fuel charger and related facility improvement project also in corresponding envelop of function, can improve in the station traffic or improve the fuel charger service ability, for improve oiling efficient also tool have certain effect.These schemes of while can be expanded application in this area, further promote oiling aerating efficient.Fuel charger, filling machine by fuel charger and related facility improvement project and the making of expansion application scheme thereof are compared existing same category of device, have expanded the filling distance, and can avoid unnecessary interference, have improved service ability.
