Description

The invention relates to mobile automatic refueling devices and can be used for storage and refueling of vehicles with oil products.

The prior art container filling station (RU 40969, publ. 10.10.2004) containing a filling container and an operator’s container. In the refueling container on the platform platform, a sectional ellipsoid profile tank is installed, having a stiffening frame with a guard mounted on it, made of durable porous material in the form of a parallelepiped with rounded corners. At the top of the fence, a service platform is installed, turning into a canopy for a fuel dispenser mounted on a pallet platform. The tank is equipped with a sensor for monitoring the fuel level in it, pipes for receiving and dispensing petroleum products, and a flame arrester. The operator’s container is made with glazing from the side of the refueling container, equipped with a control panel for the refueling container and the illuminator of the fuel dispensers.

The disadvantage of the above utility model is that the tank of the refueling container is located directly in the refueling container and is charged with oil through the intake pipes, that is, the oil is poured from the tank for transportation, for example from a tanker, to the tank for storing the oil. When filling the tank of the refueling container in this way, the oil product contacts the air containing various impurities and water particles, and thereby the quality of the initial oil product deteriorates.

In addition, it takes time to replenish the fuel reserves in the tank of the filling container, therefore, the uninterrupted operation of such a gas station is not ensured.

A significant drawback is the lack of fire sensors and an automatic fire extinguishing system, which worsens the explosion and fire hazard in the area of a gas station. Since this station is mobile and can be located in places remote from the locations of the fire station, the presence of an automatic fire extinguishing system is necessary. The gas station should also be equipped with fire detectors, as the operator may not always notice and prevent a fire or explosion on time.

The closest analogue of the claimed invention and adopted as a prototype is an autonomous gas station container station (RU 91700, publ. 27.02.2010, bull. No. 6). An autonomous filling container station consists of a fuel storage container containing oil product tanks with breathing valves, inspection hatches, metering devices and sludge drain holes, filling pipelines connected to pumps, and oil distribution pipelines connected to fuel dispensers, a single partition wall between tanks and technological compartment, technological compartment doors with movable elements designed in a sparkless design, about netushiteli located on site service, is installed on the fuel storage container, the collection container emergency oil Strait, with a drain pipe, the control parameter sensors. The fuel storage container contains an additional technological compartment, reservoirs for oil products are made with double walls and stiffeners installed in the interwall space, automatic fire extinguishing modules are additionally installed in the technological compartments and fire detectors and detectors are mounted, sensors for monitoring the level of oil products are installed as parameters monitoring sensors in tanks and pressures in the inter-wall space, while fire extinguishers at the service site are set Lena extinguisher, automatic type, are installed in the pump compartment, explosion-proof autonomous control panels, and in fuel-compartment set terminal for inputting information.

The disadvantage of this utility model is that the tanks contain technological compartments for receiving and dispensing petroleum products. This design of the tanks requires the overflow and topping up of oil from transportation tanks to the tanks for storing the oil, and during the overflow or topping up of the oil, it comes into contact with the air, which negatively affects its quality.

In addition, oil storage tanks are equipped with breathing valves through which air enters. When the oil product is dispensed, its quantity in the tank decreases, and air is supplied to the tank to maintain optimal pressure. The air mixture containing dust, various impurities, water particles, settles in the form of condensate on the walls of the tank, mixes with its contents, thereby impairing the quality of the oil product.

The replenishment of fuel in tanks for storing fuel is carried out by overflowing from tanks for transportation to these tanks. This entails time costs.

The invention is aimed at improving the quality of petroleum products sold at mobile gas stations, and reducing time spent on replenishing petroleum products at such gas stations.

The technical result is achieved in that a mobile automatic refueling complex comprising a refueling container with side and end walls and technological compartments installed inside the refueling container, at least one fuel dispenser, sensors for monitoring the parameters of the oil product, a pump for supplying oil products, fire sensors and detectors , gearbox, automatic fire extinguishing system, controller, payment terminal, control room, contains at least two tank containers for i transportation and storage of oil product, hermetically connected by means of a fuel pipeline with a fuel dispenser and installed separately from the refueling container, and a gas station installed in the refueling container, made in the form of a cryogenic tank with inert gas, connected to tank containers for transportation and storage of oil product help gas pipeline.

The claimed invention involves the use of tank containers as a reservoir for both transportation and storage of oil at mobile gas stations, and the release of fuel in turn from two tank containers connected to a gas station to supply inert gas instead of air, without overflow of oil from the tank for transportation to a storage container. Thus, the contact of the oil product with the air is excluded and the uninterrupted operation of the gas station is ensured. Gas creates an inert cushion in the fuel space of the tank container, which increases as it is emptied, and there is no need to supply air to it, as well as equip the tank container with a breathing valve. Due to the exclusion of contact of the oil product with air due to the lack of operations of the overflow of oil from the tank for transportation into the tank for storage, the quality of the original oil product is improved.

In addition, due to the inert gas entering the tank container, an inert fire and explosion-proof environment is created and constantly maintained in it.

In FIG. 1 shows a diagram of an autonomous mobile gas station.

Mobile automatic refueling complex (Fig. 1) includes a refueling container with side and end walls and technological compartments (1), installed inside the refueling container (1), at least one fuel dispenser (2), at least two tank- a container for transporting and storing oil product (3), hermetically connected by means of a fuel pipe (4) to a fuel dispenser (2) and installed separately from a refueling container (1), a gas station (5) installed inside a refueling container Era (1) and connected to tank containers (3) using a gas pipeline (6) equipped with a gearbox (7), a pump for supplying oil products (8), fire sensors and detectors (9), an automatic fire extinguishing system (10), controller (11), payment terminal (12), control room (13), oil product control sensors (14).

The filling container is made in the dimensions of a standard transport container and equipped with fittings for easy transportation.

The fuel pipeline is connected from the tank containers through the technological compartment of the refueling container to the fuel dispenser. The connection of the fuel pipeline with each tank container is sealed and quick disconnect. The technological compartments of the filling container are equipped with ventilation.

The gas pipeline is connected from the gas station through the technological compartment of the refueling container to the tank containers.

The complex is controlled by a controller connected to the control center via wireless communication, for example, via the Internet.

The mobile automatic refueling complex is equipped with a lightning protection and grounding system, the components of which are transported inside the refueling container (not shown) during transportation.

Mobile automatic fueling complex operates as follows.

A refueling container is installed at the facility. Tank containers filled with oil product are placed at a certain distance. Using the fuel pipeline, tank containers are connected through the technological compartment of the refueling container to the fuel dispenser. Using the gas pipeline, tank containers are connected through the technological compartment of the refueling container to the gas station. After that, the door of the refueling container is locked.

In the tank containers, the oil is under a pillow of inert gas, which permanently enters it from the gas station. During refueling, the amount of oil in the tank container decreases, and the inert gas cushion increases. Oil product is dispensed from tank containers in turn. When the fuel level in the tank container reaches the minimum value, the fuel parameter monitoring sensor gives a signal, the tank container is disconnected from the fuel dispenser and switched to the filled tank container. An empty tank container is replaced with a full one. This ensures the constant availability of the oil product at the refueling complex and reduces the time spent on supplying gas stations with oil products.

Thanks to the inert gas cushion, which does not react with the oil product, the fire and explosion safety situation at the gas station is improved and the quality of the oil product in the tank container is improved, because when the tank container is partially emptied to maintain optimum pressure in it, it is not air with various impurities that enters it, but gas inert with respect to the oil product and the material of the tank container.

A mobile automatic fueling complex is controlled by a controller connected to a control room via a wireless network, such as the Internet. The controller manages oil product dispensing operations and sends signals about the state of the complex to the control room, where all information about the operation of the specified complex is accumulated.

The power supply of an autonomous mobile gas station is carried out directly from transformer substations or from a diesel generator set.

Mobile automatic fueling complex is easily transported on open railway platforms, in cars with an open body, easily located in any, even remote and inaccessible terrain. This is achieved by the fact that for this complex it is not necessary to build large platforms, operator rooms, place them on the shopping center floor and make a canopy for them. The terminal, sensors and controller are configured at the installation site by maintenance personnel.
