DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a shielded assembly for the delivery of fuel entirely disappearing into the ground and adapted to be used as gasoline pump in civil, in particular military, airports and heliports, bus stations, garages, gas station, said assembly comprising a gasoline pump vertically displaceable between an operative position and a concealed, shielded rest position in which it is entirely received in a casing buried in the ground and closed by a rugged manhole cover which is effraction-free, the vertical movements of the displaceable pump being controlled by a hydraulic cylinder and piston assembly coaxial with the telescopic pipes supplying the gasoline pump with the fuel of the tank.
The emerging need of providing civil and military installations, remote, inhabited and non-inhabited places with fuel delivering plants as well as the concomitant need of assuring to such plants the maximum security against any attempt of effraction, tampering and sabotage even without service personnel has brought to conceive and design the shielded, entirely disappearing assembly of the present invention.
Such assembly has the maximum versatility and ductility of employment since it is adapted to be used as a shielded plant having size and dimensions varying from that for the refuelling of great civil and military aircrafts, helicopters, watercrafts and the like to that for a gas station for civil and commercial motor vehicles of any type using gasoline, Diesel oil and the like.
In its embodiment of larger size and greater dimensions the assembly of this invention is preferably connected through pipings to one or more buried tanks from which it draws off the fuel. Furthermore it is connected to the tank through a manhole easily practicable so as to allow the tank to be reached for check, maintenance and cleaning purposes.
The basic feature of this assembly is that it has a casing or exterior body entirely received in the ground, with respect to which the whole assembly of the delivery and control means, the filters and so on can assume two different positions as it will be better apparent thereafter.
In a first non operative position the assembly is entirely received and concealed in such exterior body, while in a second operative position the assembly rises from the exterior body and the ground so that the operator is allowed to operate the assembly and to control the fuel delivery.
It should be appreciated that the top of the vertically displaceable assembly is formed of a rugged armoured plate sealing the opening of the exterior body and lying on a level with the ground in the non-operative or lowered position of the assembly.
Further important features are that the first step of the raising movement of the armoured plate causes a central "plug" of the same to be partially opened in order to promote the outlet of any gas collected within the assembly; the raising of the assembly is effected by means of a hydraulic cylinder and piston assembly, the operation of which is controlled by a magnetic key placed on the armoured plate; the operating key has a built-in flashing light signalling the movement and the opened position of the plate; the armoured plate is surrounded by an opening for the outlet of the rain water; the manhole between exterior body of the assembly and fuel tank is closed by a sealing door provided with control wheel.
It should be noted that the raising assembly of the gasoline pump is also a means of supplying fuel from the tank to the delivery reel.
In other words the operation features of the assembly, comprising as better explained thereafter all of necessary, suitable, essential means for the delivery of fuel, are as follows:
supplying the tanks connected thereto with fuel drawn off from tanks and pipes outside the assembly after pumping, cleaning and gauging thereof;
self-contained airport fuel tank assembly;
standard gas station disappearing in the ground for supplying aircrafts, watercrafts, land transport means or stationary installations (turbine test stands, industrial plants)
