Description

The invention relates to the field of gas equipment, namely to the field of refueling, storage and transportation of compressed gases and their mixtures in cassettes with high-pressure cylinders, used, in particular, on vehicles operating on gaseous fuels.

A container for transporting gas cylinders is known (see patent RU No. 160155, U1, class B65D 90/18, published March 10, 2016), which is intended for storage and loading / unloading of gas cylinders with compressed or liquefied gas and refers to special containers for placement on a vehicle designed to deliver gas, in particular methane, to gas distribution points remote from gas pipelines. Known container provides ease of operation by ensuring smooth running of the container. However, it has an increased downtime for refueling (waiting for a refueling queue, time for preparing a vehicle for refueling, and time for refueling all cylinders).

A known container of cylinders for compressed gas (see patent RU No. 42201, U1, class B60K 15/07, publ. 11/27/2004), designed for quick dismantling / installation of cylinders from a vehicle, for example, when sending cylinders for technical examination or replace empty with refueled ones. The container is made with the possibility of hermetically closing its internal cavity when cylinders are installed in it, while at least one sensor is installed in the internal cavity of the container for detecting and signaling the presence of gas in the internal cavity of the container. However, the need to dismantle / assemble each individual cylinder from the container for sending cylinders for technical examination, or to replace empty ones with refilled ones, takes a long time, as the bus is forced to stand idle all the time while removing and installing new cylinders in the container, each separately.

The objective of the invention is to create a device for servicing a cartridge with gas cylinders, devoid of the above disadvantages.

The technical result to which the invention is directed, increasing the efficiency of the container by providing refueling of gas cylinders placed in cassettes with gas cylinders intended for installation on gas-filled vehicles by eliminating idle runs, its downtime during the process of refueling or inspection of a large the number of gas cylinders; providing refueling in motor transport enterprises, at multi-fuel automobile gas stations, and in rotary-settling platforms.

The invention consists in the following. The container includes a metal housing designed to accommodate cartridges with gas cylinders. The container contains at least three sections separated by partitions, in each of which guides are provided with locking mechanisms and rollers mounted on the guides, designed to provide smooth loading and unloading of cartridges with gas cylinders. A control and measuring panel is built into the rear wall of the metal casing; high pressure pipelines and a splitter are located on the inner surface of the metal casing, which ensure that gas cartridges with gas cylinders are refilled with compressed natural gas through an external refueling device. At least one external refueling device is mounted on a control and measuring panel, which also includes inlet pressure gauges and a refueling line.

The technical result of the invention is achieved through the use of the proposed container - refueling device for servicing cartridges with gas cylinders with compressed natural gas (CNG). Cartridges with gas cylinders are installed in the container - the tanker is empty (empty), removed from the vehicle (pre-charged cartridges with CNG are installed on the gas-cylinder transport system). Through the use of the proposed container, refueling of CNG cassettes removed from the vehicles is carried out, their maintenance and transportation to the place of refueling, storage and delivery.

Cassettes with gas cylinders filled with CNG are located in the proposed mobile container. Cassettes with cylinders, in particular, used for buses, trucks and other vehicles with a large volume (quantity) of gas cylinders, must be serviced (stored, transported, refueled). For storage, transportation and refueling of cartridges with cylinders it is proposed to use a container made on the basis of a metal case, for example, a sea container used for transporting heavy loads.

The essence of the claimed invention is illustrated by drawings (Fig. 1-3), which shows the design of the proposed container. In FIG. 1 shows the appearance of a container intended for placement at a gas station in an automobile gas-filling compressor station. Cartridges with CNG cylinders can be loaded into such a container (Fig. 1), for example, in an amount from one to 36 if the container is, for example, 20 feet (6.096 meters) long, and from one to 84 for a container whose length, for example, is 40 feet (12.192 meters). In FIG. 2 shows the rear wall of the metal casing; FIG. 3 is a front view of the proposed container with open swing doors through which cassettes with gas cylinders are loaded into the container. The composition of the proposed container (Fig. 1-3) includes: at least one portable refueling device (1); metal case (2); high pressure gas pipeline (3); splitters (4), for example, type "Crab"; refueling devices (5) for cartridges with CNG cylinders; input pressure gauge (6); refueling line pressure gauge (7); control and measuring panel (8); rollers (9); locking mechanism (10).

The operation of the container is as follows.

High-pressure natural gas, previously cooled and drained through an external filling device (1), enters the high-pressure gas pipeline (3) located along the ceiling, walls and partitions of the metal case (2) of the container, through splitters (4) to the filling devices (5) ) intended for refueling cartridges with CNG cylinders installed in the container. Cassettes with CNG cylinders are placed inside the metal casing of the container, separated by internal partitions, into at least three sections. Inside the metal housing (2), on both sides of each of the sections, guides are provided, equipped with locking mechanisms and rollers (9) integrated into the guides, through which the cartridges with cylinders are loaded and unloaded into the container.

Using a gas hose, a container is connected to an external refueling device (1) located on the rear surface of the container. Natural gas is simultaneously supplied to all refueling devices (5) installed in the cartridge container with CNG cylinders.

Refueling of gas cylinders placed in cassettes is visually controlled by observing the readings of pressure gauges (6 and 7) placed on the control and measuring panel (8), which is built into the rear wall of the metal case. At the end of refueling, the high pressure gas pipeline (3) is shut off. The filling device (1) is turned off. The doors of the container body are closed, and the container can be moved to a storage platform or mounted on a platform, semi-trailer or trailer for transporting containers (container carrier).

The invention allows for the simultaneous filling, transportation and storage of cartridges with CNG cylinders for compressed (compressed) natural gas without the need for additional operations to move, connect / disconnect refueling devices within an automobile gas-filling compressor station. The invention also eliminates the need for hanging or turning cartridges with cylinders with CNG for connection to a filling device placed on the CNG container. If the stopper (10) of the cartridge with cylinders with CNG is closed and the pressure in the cartridge decreases compared to the pressure in the gas pipeline, the check valve of the cartridge with CNG opens through the filling device mounted inside the cartridge (5). Natural gas from the high pressure pipeline (3) enters the filling device (5), and then into the cartridge cassette. Indication of the current pressure at the inlet of the refueling container is displayed on the pressure gauge (7) located on the control and measuring panel (8). Refueling stops when all the cartridges of the container reach a pressure equal to the pressure at the inlet of the refueling device.
