Description

The field of technology

The invention relates to a relocatable station for pumping liquids with a base cabinet formed by a supporting frame with an outer casing, where a storage compartment with hydraulic distributions and a technological compartment with wiring and a control system are arranged in the inner space of the base cabinet, while at least the storage compartment is equipped with an inner casing.

Current state of the art

Classic stationary gas stations for pumping liquids, especially fuels, are characterized by the expensive construction of a service building and underground tanks, including the necessary security against possible fuel leakage, contamination of the surrounding soil and environmental pollution. Attendance is essential at these stations, at least at the checkout. Gas stations are often open 24 hours a day. After that, additional workers are needed who take turns in operating the station. In the event that a station is taken out of service, either due to the repair of the station itself or the repair of the road, which can also be unexpectedly long, and the next station is far away, the fuel supply in the given place is significantly impaired. In these cases, as well as when it is necessary to establish a new station quickly and the time necessary for the construction of a classic station would greatly delay its commissioning, the establishment of a fully above-ground station, which can only be in operation for a limited time, or permanently, is a suitable solution , as needed. Such stations are advantageously built as unmanned, where the customer not only draws the desired amount himself, but then pays cashless using cards of various types, depending on which the device system is set to. Temporary or relocatable gas stations are already known and there are a number of different solutions to the above problem situations. For example from the document WO200220393, the principle arrangement of an unattended gas station equipped with a dispensing stand with a dispensing gun, a control unit and a service unit with a device for handling a payment card and a device for transferring data to the control panel is known. It is thus possible not only to execute payment orders, but also to monitor the stock status in this station and ensure timely replenishment, react to the status of the station, e.g. in the event of an unauthorized intervention, etc. Some mechanical problems, especially increasing the rigidity of the frame for transport and the placement of individual devices, are solved in the implementation of a filling station built into a container, described e.g. in PCT file WO2003000584 and WO2006066515. The problems of possible mechanical failures in the structure, especially in the part of the storage compartment, are solved by the design described in EP 2969909. However, in addition to mechanical failures, accidental but nevertheless dangerous situations can arise, such as the impact of a moving vehicle into the station or the ignition of fuel, whether caused by any the cause. The subsequent explosion would scatter the station in all directions and cause considerable material damage, undoubtedly accompanied by loss of human life. Existing constructions do not solve such a situation.

The aim of this invention is to limit the possible damage caused by fuel ignition and the subsequent explosion of the station.

The essence of the invention

The stated purpose is achieved with a movable station for pumping liquids with a base cabinet formed by a supporting frame with an outer casing, where a storage compartment with hydraulic distributions and a technological compartment with electrical installation and a control system are arranged in the inner space of the base cabinet, while at least the storage space is equipped with a casing, in the embodiment according to the present invention, the essence of which is that the inner shell is equipped in its upper part with at least one weakening over-molded along the supporting frame. Furthermore, according to this invention, the weakening press is made both on the upper part of the inner shell and on the upper part of the outer shell. Likewise, according to this invention, the weakening press is made both above the storage section and above the technological section of the station. In the case that the station is equipped with a built-in tank, the weakening press is also made on the upper surface of this built-in tank. In an advantageous embodiment, the weakening press is guided in at least one continuous line, alternatively, the weakening press can be, at least partially, guided in an interrupted line. The advantage of this version of the container system of the gas station is that the force of a potential explosion is directed upwards, so that it does not act sideways. This significantly limits the damage that could occur in the immediate vicinity of the pump station of the given type as a result of the explosion of the stored liquid.

Overview of images on drawings

The invention is explained in more detail on the example of its practical implementation shown in the attached drawing, which shows the basic design solution of the mobile pumping station in question, designed as a container cabinet, with a partially exposed casing.

Examples of implementation of the invention

As can be seen from the drawing, the movable fluid pumping station in question includes a base cabinet, which contains a storage compartment 3 equipped with hydraulic distribution, in which the dispensed liquid is stored, and a technological compartment 4 equipped with electrical installation and a control system. The technological compartment 4 of the base cabinet also contains the filling section with the filling neck and the corresponding hydraulic distributions and the dispensing section with means for dispensing liquids, especially certified dispensers.

As is further clear from the drawing, the station cabinet structurally consists of a supporting frame and an outer shell 10. The frame is formed by columns 11 interconnected by longitudinal beams 12 and transverse beams 13. The longitudinal beams 12 are strengthened by vertical braces 14, the cross-section of which has the shape of the letter T The outer shell 10, covering each wall defined by the supporting frame, is hermetically welded to this frame. The braces 14 may or may not be made of solid material. They can be equipped with through holes, these holes are not shown in the drawings. The internal space of the cabinet is divided into a technological compartment 4 and a storage compartment 3 by a partition wall 16. The dividing partition wall 16 is equipped with technological openings for the hydraulic and electrical connection of both compartments 3, 4. The technical equipment of both compartments 3, 4 is commonly known, therefore it is not shown here not even described in more detail.

The entire storage compartment 3 is equipped with an inner shell, not shown here, which defines closed perimeter spaces against the outer shell 10 and the intermediate wall 16. The distance between the two shells is ensured by vertical braces 14. In the peripheral spaces, the pressure is artificially reduced to a value lower than the atmospheric pressure. The state of pressure in the perimeter spaces is guarded by sensors. Sensors may or may not be located in each of these spaces. The outputs of all sensors are output to the control electronics. The types of used sensors of a given type and their connection are generally known, therefore it is not part of this technical solution and, for simplicity, these sensors are not drawn on the drawing.

Although the use of the inner shell is described for storage compartment 3, it can be similarly used for technological compartment 4. There it can be part of the protection against forced entry into this compartment. The inner shell in both sections 3, 4 allows the intermediate wall 16 to be omitted.

The double shell allows the internal space of storage compartment 3 to be used directly as a tank. However, it is also possible to imagine the use of a built-in tank, but then the intermediate wall 16 is not necessary. Alternatively, the storage compartment 3 can be divided into two or more partial tanks by means of a dividing wall 15, which can thus contain different liquids. In this case, technological section 4 is executed and equipped accordingly.

According to the illustrated subject technical solution, both the inner shell (not shown) and the outer shell 10 are on their roof, i.e. j. upper part equipped with a weakening of the material in the form of an overprint 17, guided in a continuous line along the supporting frame. As can be seen from the drawing, the press-fit 17 is made only above the storage section 3, but similarly, this weakening press-fit 17 can also be made above the service section 4.

Alternatively, the pressing 17 can be done in a broken line. It is also possible to design in several parallel arranged lines. Overprints 17 represent a weakening of the material, which does not affect the overall rigidity of the station cabinet, but in the case of a significant increase in pressure inside the relevant space, e.g. in case of the explosion of the contents of the tank already mentioned, the weakened material of the upper wall shell first gives way. The force of the explosion will thus be directed upwards, the pressure on the side walls will be significantly lower, and the side walls will thus prevent the destructive force from spreading to the sides and endangering the immediate surroundings of the station.

The desired effect, directing the force of a possible explosion of the contents of the tank, is largely achieved by making overprints 17 only on the inner shell, but it is obvious that the design of overprints 17 on the upper surface of both the inner shell and the outer shell 10 is more effective.

If the pumping station in question is equipped with one or more built-in tanks, the weakening moldings 17 are made on the upper surface of all built-in tanks.

Industrial applicability

The transferable station in question is designed for refueling at permanent and temporarily established stations. However, it can be used to pump and dispense any type of liquid.
