MODULAR SYSTEM FOR LIQUID DISTRIBUTION AND STORAGE

The invention relates to a module system for arranging, for example, the distribution and storage of flammable liquids, which includes an underground liquid tank, a refueling pier above the tank with distribution equipment and a canopy.

5 A conventional fuel distribution station shall be constructed, without a store building, by excavating an installation pit in the station area for each underground tank to be located. The locations of the tanks will be drained and inspection wells will be installed. In addition, the foundation of the canopy structure will be built separately, on which the so-called pier with fuel distribution equipment and canopy structures. Tanks are lowered into the installation pits and air and filling pipes are installed in the tanks. Between the tanks and the distribution plant there will be trenches for fuel piping 15 and electrical cabling. The tanks are already tested at the factory, but the pipes going to the distribution equipment cannot be tested at the installation site.

The object of the present invention is to eliminate the above-mentioned problems and to provide a new modular system, the structures of which have taken into account in the distribution and storage of flammable or similar liquids, e.g. the prevention of fuel leaks is very important for the environmental protection of the distribution station j 94888.

Among the previously known modular systems for the distribution of fuels, the following can be mentioned: U.S. Patent 2,182,126 describes a system with a cover bracket connecting the distribution devices, which is a rectangular housing structure which is open from below and the cover has openings below the distribution devices. U.S. Patent 2,959,826 discloses a dispensing station 10 having a cover console connecting dispensers, which is a rectangular housing structure having tube openings in the lid below the dispensers. U.S. Patent 3,288,321 discloses a dispensing station having a housing console connecting dispensing devices, the lid of which has tube openings below the dispensing devices.

Such a system in which a collecting trough is formed in the console connecting the distribution devices and in which the end pool has an end basin is not previously known.

Figure 1 shows a side view of a module system according to the invention for arranging the distribution and storage of flammable or similar liquids. The module system consists of 15 pre-built components. The base body of the modular system is formed by cones 16 and a liquid container 11 to be attached to them. Footrests 13 are attached to the liquid container 11, on which the liquid container is mounted on top of the cones. The liquid container 11 is aligned with the base flange mounting grooves 16a in the cones 16 by means of the foot flanges 20. The base flanges 13 and the cones 16 of the liquid container 11 are locked to each other by locking pins 18 pushed through the holes 17 and 17 '.

The edges of the end bases 15 at both ends of the center console 14 form a box-like liquid-retaining basin with a support plate 25 attached to the base jacket * ·: 27. Inside the end basins 15, the base housings 21 of the roof columns 20, supported by a partition wall 24, are built. A station canopy 23 is mounted on the posts 20.

Fig. 2 shows the module of Fig. 1 as a side view of a flammable liquid distribution station 10 assembled by the system. Conicals 16 made of, for example, concrete or similar material are installed as the base of the flammable liquid distribution station 10. The cones 16 have been brought ready for installation from the foundry to the construction site. The concrete cones 16 are lowered for installation on the leveled bottom 9 of the installation pit or, alternatively, they can be installed as a surface installation on a flat ground.

Mounted on the concrete cones 16 is a liquid tank 11 consisting of a corrosion- and wear-resistant glass-fiber-coated steel tank. To the single or double jacketed 15, in practice multi-part, liquid container 11 provided with liquid container units 12 separated by a partition 26, the base jackets 13 are attached by welding, on which the liquid container is mounted on the cones. The liquid container 11 is aligned with the mounting notches in the concrete cones 16 by means of base flanges 13.

On both sides of the base flanges 13 · [*. if necessary, rubber seals can be installed, which insulate- ^. · Separate the cone and the fluid reservoir and prevent abrasions between the cones and the fluid reservoir surfaces and reduce the generation of static electricity. Since the concrete cones • ·: 16 act as a base for the distribution station 10, calculated in the installation pit, the load-bearing capacity of the base does not depend solely on the liquid tank, so that the weight distribution is even and controlled.

Once the fluid tank is installed and the installation pit is covered again, the roof structures are installed in place. Inside the end basins 15, partition walls 21 of the roof columns 20 supported by a partition wall are built. The columns 20 are fixed from their lower end flanges 22 by a bolt connection to the fixing flanges 22 'of the base housings 21 in the end basins of the cover console 30. A canopy 23 of the station is mounted on the posts 20. The posts of the canopy 23 are enclosed and spacious enough to accommodate 10 rubbish bins, tools, sanitation, oil and fire-fighting equipment and an electrical switchboard. Prefabricated prefabricated roof structures have been built on the columns 20 at the factory, which include the necessary lights, advertisements, etc. After the connection of the electric and telecommunication cables, the distribution station 15 can be put into operation immediately.

Figure 4 is an axonometric view of the structure of the top console 30 of the module of Figure 1 included in the system. At the factory, a fixed top bracket 30 is formed by welding to the upper part of the liquid tank 11, which consists of a center bracket 14 and an end basin 15. The solution used 15 differs substantially from the previously known structures used in flammable liquid distribution stations. The center console 14 is a substantially rectangular pool comprising sides 14a, a base 14b and a sealed lid 14c.
